GEORGE VAN WAGENEN, OF NEW YORK, N. Y.

COMBINED SHEARING AND PUNGHING MACHiNE.

SPECIFICATION forming part of Letters Patent No. 484,832, dated October 25, 1892. Application filed July 14, 1890- Serial No. 368,741. (No model.)

To all whom it may concern:

Be it known that I, GEORGE V AN WAGENEN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invent-ed certain new and useful Improvements in a Combined Shearing and Punching Machine, of which the following is a specification.

The invention relates to improvements in combined shearing and punching machines for sheet metal; and it consists in the organization and combination of elements hereinafter described, and particularly pointed out in the claims.

The machine which has been made the subject of this application was designed and built by me for use particularly in the manufacture of'the sheet-metal sngar-wagonsdescribed and claimed in Letters Patent of the United States granted to the Geo. Van \Vagenen Company on the 27th day of May, 1890, being numbered 428,790, and for such manufacture it has been especially efficacious. The bodyof said sugarwagon is composed of five pieces (the ends, sides, and bottom) sheared from long sheets of steel, the edges of the sides and ends being cut at an angle to the length of the sheet and .of apertures in proper alignment to permit riveting-machine.

the' riveting being rapidly completed by a v It has been my purpose in the construction of the present machine to secu re great durability and effectiveness with simplicity of construction and the minimum withdrawn and others substituted for them.

The special'featurcs of construction, with their mode of operation, will appear more fully in the detailed description hereinafter presented.

Referring to the accompanying drawings, Figure 1 is a front elevation of a machine constructed in accordance with the invention; Fig. 2, a transverse section of the same on the dotted line 2 2 of Fig. 1; Fig. 3,2. vertical section of the same on the dotted line 3 3 of Fig.

I; Fig. 4, a detached vertical section similar to Fig. 3, but illustrating the application of the series of punches to the carrier. Fig. 5 is an enlarged sectional view of the same;

Fig. (i, a detached front elevation, partly in section, of the punch-bar with the punches in position; Fig. 7, a vertical section Of Sftld punch-bar on the dotted line 7 7 of Fig. 6;

Fig. 8, a top view, partly broken away, of the tions E over theirsurfaces to receive the bolts F, by which the gages G may be secured in place in any desired position and at any requisite angle. The platforms 0 I) are pro-.

'vidcd with,a number of perforations E, in order that gages G may be shifted and arranged with respect to each other at will, in accordanccwith the character of the sheets to be cut and the angle at which it is desiredto punch their edges.

Upon opposite sides of the bed ll are provided the standards II, which are secured to the bed-plate B by bolts I, as shown in Fig; 3, and are connected at their upper ends by the bar J. (Illustrated more clearly in Fig. 1.) The standards II are substantially vertical on their front edges and at their rear sides are formed with the rcarwardlyextending brackets K, through which the bolts I pass into the bed I Beneath the standards II are formed the recesses L, opening frontward, as illustrated in Figs. 3, 4, and 5, and the purpose of which will be hereinafter explained.

My reason of the employmentof the brackets K and bolts 1 in themannerillust-rated in Fig. 3 I am enabled to form the recess Ii in the lower face of the standards Hwi'thout detriment to the durability and 'efiectivenes's' of the machine. In the upper ends of the standards His journaled the shaft M, upon which by means of the links N is suspended the carrienba'r O, to which the knife and punches are secured. The middle portions of theshaft M are journaled in and sustained" by the bearings P, suspended from the tie-bar J. The ends of the carrier-bar enter and are guided by vertical slots formed in the standards H, (shown by dotted lines in Figs.

1 and 2,) thepurpose being to insure a direct vertical reciprocating movement in said carrier-bar under the action of the crank-shaft M and linksN.

' pockets to receive the dies X. Upon the rear side of the carrierbar 0 is secured by boltsa the knife-bar b, which carries at its lower inner edge the knife (1, as illustrated in Figs. 3 and 5, whichco-operates with the lower knife or cutting-edge e, secured to the upper rear.

edge of the rib R. Upon the front lower portion of the carrier-bar is provided the recess f to receive the punch-bar g, thelatter being secured in place by bolts h. ,The punchbar 9 has above it the steel plate '5 to prevent the upper ends of the punches (letteredj) from bruising the metal du ring the operation of the machine. The punch-bar g is an elongated bar extending transversely across the machine, being secured, as illustrated in Fig. 5, to the carrier-bar O, and contains a series of apertures k to receive the metal cylindrical pockets on, having the shoulders 11. at their upper ends to rest upon a correspondingshoulder formed in the punch-bar. The pockets m are adapted to be inserted into and withdrawn from the punch-bar g at willand are adapted to receive the punchesj, which extend downward a proper distance below the pockets m, the latter also extending below the punch-bar g a snfiicient distance to properly sustain the punches. The upper ends of the punches j may be headed,asillustrated in Fig. 7, for the purpose of preventing their withdrawaldownward from the pockets, or a like efiect may be secured by means of screws 7, extending through the punch-bar and pockets and engaging the punches, as illustrated in Fig. 9, the only object in either construction being to prevent the metal from drawing the punches from the pockets. The steel platet' above the;

punch-bar 9 receives the pressure at th e u p per ends of the punches j, and thereby prevents the carrier 0 from being bruised or roughened during the operation of punching.

. As will be observed in Fig. 6, the punches j vary in length, and hence when in use all of the punches will not simultaneously engage the metal to be punched, but will gradually one after another enter the same, and thus insure the proper punching of the holes without splitting the metal or jarring the machine. It will be readily understood that the punch-bars and die-bars will correspond in respect to' the vertical plane of the apertures formed in them to receive the punches and dies, respectively,

and that these bars will be removed and others substituted for them, according as it may be desired to punch holes varying in distance from each other. The punches j are independent of each other, and hence should any one become broken or bent it alone may be withdrawn from the punch-bar g and another quickly substituted in its place. The punches j consist simply of sections of drawn -steel rod tempered at the point or entering end, and henceit will be understood that they may be very inexpensively and quickly made and that no particular expense will be incurredin keeping a supply on hand. The pocketsm effectually sustain the punches j and enable them to be quickly inserted in position or transferred from one punch-bar to another.

As above described, the die-bar W is allrectly below the punch-bar g and is provided with dies X, adapted to receive the points of the punches 7' after the latter have passed through the sheet of metal to be punched, said sheet being illustrated in Figs. 3, 4, and 5 and lettered t. The die-bar W may also be readily withdrawn from the machine at will, since it simply rests .in the pocket V, being there held 'by bolts m, which pass through a section of the bed-B and engage the front side of said bar. In the upper face of the bed B are formed the recesses as, through which the bolts 20 are passed and which permit the introduction of said bolts without leaving any elevations upon the surface of the bed B to interfere with the proper handling of the sheets of metal to be sheared and punched. I

Upon the bearings P are secured the upper ends of the plates A, which extend downward and are connected by bolts with the upper ends of the plates B, which extend downward to within a short distance of the upper face of the bed B and pass through loops C, secured to the front edger the carrier 0, as illustrated in Figs. 1 and 3. v

The plates A B are connected by the bolts, as illustrated in Figs. 1 and 3, for the purpose of making them adjustable asto their length; but it is evident that, if desired, these two IOC plates may be made from a single piece of material instead of two 'it a vertical adj ust- .ment is not preferred. Upon thejface of the plates B" are secured the bearings D, in' which the rock-shaft E is journaled. The rock-shaft E carries the knuckles F, to which are piv-. o ted the links G, carryiu g at their lower ends the presser-bar H, which extends transversely across the machine and has its e'nds guided Fig. 5.

in the plates 1, as illustrated more clearlyin Fig. 1. Upon the rock-shaft E is also secured the arm J', carrying the counterbalance-weight K.

When the arm J and weight K are in the position illustrated in Fig. 3, they cause a pressure through the links G and bar H upon the sheet of metal if, resting upon the table B;

but when the arm. J and rod' K are turned,

upward to the position illustrated in Fig. l the rock-shaft E is caused to rotate in its bearings D and through the knuckles F elevate the links G and bar H, thus releasing the sheet of metal tand permitting its removal or adjustment at will. It will not be necessary at all times to make use of the presser-bar H, with its connecting mechanism; but I recommend its use, particularly during the operation of shearing, since the eifect of the bar is to firmly hold the sheet of metal uponthe table Band facilitate the successful operation of the machine. When, however, the punching alone is being carried on or the shearing and punching carried on together, the bar llhvill be withdrawn from the machineand astripper-plate L applied over the die-bar W,as'illustrated in Figs.5 and 8,said

bar being bolted to the transverse carrier-bar M, which at its ends is bolted to the standards H H adjacent to the bed B. The stripper L contains a series of apertures N, arranged directly over apertures inthe dies X andcentrally below the punchesj. The stripper L in the form of an angle-plate and is secured at a proper elevation above the bedplate B to permit the introduction of the sheet of metal t beneath it, as illustrated in During the operation of punching the stripper L prevents the end of the sheet of metal I; from being carried upward by the punchesj. When the opdr-ation-of punching is being carried on alone, I prefer to apply the gage O to the upper surface of the bed B, beneath the carrier 0, as illustrated in section -in Fig.5, for the purpose of engaging the edge of the sheet of metal tand insuring the apertures being formed at the proper position in said sheet :5. The gage consists of a strip ofrnetal held down by screws, and it may be adjusted in accordance with the distance the apertures are to be punched from the extreme edge of the sheet of metal. Dur ing the operation of shearing and punching at one time the gage 0' will not be made use oi", since under these conditions it will'be necessary for the sheet of metal 6 to project beyond the cutters (Z 6 in order that its edge may be sheared. It Will be noted upon reference to Fig.5 that the location of the cutters d c with relation to the punchesj is such that both operations may be carried on together without ditliculty, and also that'when;

it is desired simply to shear the metal the punch-bar 9 may be withdrawn from, the machine, or when it is simply desired to punch the metal the knife'bar b may bewithdrawn. It, will not be necessary, howe er, to withdraw the knife-bar b from the carrier 0 during the operation of punching unless the cation of the apertures to be formed in the sheet if is such that its extreme edge should be extended beyond the vertical plane of the cutters d e. If it should be desired to shear and punch or either shear or punch a sheet of metal Wider than the space between the inner ver! tical faces of the standards II, said sheet will have its outer portions passed into the-recesses L beneath the said standards, these recesses permitting the adjustment of the sheet transversely across the machine at will, in order that the operations of punching and shearing may be conveniently carried on to meet the requirements of any special size or form of sheet. During the operation of simultaneously shearing and punching I prefer to remove the rock-shaft E, arm J, weight K, links- G, presser-bar H, and guide-plates I and substitute for them the stripper L,it s

carrienplate M being at such time bolted to the lower front face of'the standards H. The stripper L, although not exerting the positive downward force of the presser-bar H, is but a slight distance above the bed B and will eifectually prevent the sheet of metal 6 from being carried upward by the punches or tilting downward under the action of the cutters.

, As will be understood, the gages G will be shifted in accordance with the angle on which the sheet of metalis to be out. It will not be necessary that the sheet of metal when placed on the machine shall engage all five of the gages G shown in Fig. 2; but it is desirable that it shall firmly rest against one of the longitudinal or side gages, and also under some conditions against one of the transverse or end gages. After the desired angle on which it is desired to shear or punch has been determined the gage may be set accordingly, so no that each successiveshect placed against them will be sheared and punched, as desired, without the heretofore necessary preliminary of measuring and marking oil the angles on the sheet. I I 5 The punches and pockets m are adapted for use either singly or in series, whether combined with the special punch-bar shown, or with some other form of holder for the pooh ets. The pocket m serves as a. socket to re- :20

ceive the plain straight punch and to sustain it throughout the greater portion of its length, the entering end of the punch enlybeing exposed. lftis immaterial when. only a. single punch, for instance, is used whether the pocket I 25 m is held by the punch-bar shown or by any of the other well-known appliances for holding punches; since the pocket will edectually sustain the punch and admit ot the latter being formed from a plain rod of a diameter cor- 13o responding with that of the holes to be formed. Should under-any circumstances the punchrod become bent or brdken, the pocket on will remain unaffected and be ready to receive theentirepunch, in-

In accordance with m, which dispenses the old punches, is e point of. the punch apable as ever of havin punch-rod slipped ed, also, that the cars front and rear edges nd knife bars, respectrength to the structure, eessed to receive the dieer cutter, thereby firmly sustaincluding its thick stock.
