DRAFTRIGGING FOR RAILWAY-CARS- i SPECIFICATION forming part of Letters Patent No. 779,088, datedJ'anuary 3, 1905.

Application filed December 11, 1903. Serial No. 184,799.

To all whom it may concern:

Be it known that I, JAMEs E. GUINN, a citizen of the United States, residing at Lebanon, in the county of Laclede and State of Missouri, have invented a new and useful Draft-Rigging for Railway-Oars, of which the following is a specification.

My present invention relates to draft-rigging for railway-cars, and is designed with special reference to the improvement of the rigging disclosed in my Patent No. 7 03,956, dated July 1, 1902. In the patented construction the rigging is so arranged that the strain is applied to the car-body both in front and in rear of the body-bolster and is resisted in large measure by the bolster and the cartruck connected to the bolster by the usual Such an arrangement precludes the possibility ofthe rigging being pulled out, which frequently happens when the rigging is attached to the sills of the car in advance of the bolster. In this construction the draft-timbers of the rigging are passed through a bolster comprising separated upper and lower members and extend both in front and in rear thereof. The timbers are spaced by a filling-block secured thereto by keys and apertured for the reception of the kingbolt. Beyond the opposite ends of the fillingblock are located draft and buffer springs opposed to cross-heads connected by draw-rods, and to one of these heads the draw-bar of the coupler is attached.

It has been found by continued experiment that while the patented construction is entirely efficient in connection with cars of ordinary capacity it is necessary to utilize either a solid bolster or one having a central support in cars of great capacity.v In such cars, therefore, it is impossible to extend the draft-timbers and filling-block through the bolster, and if the rigging is confined to that portion of the car lying in advance of the bolster the very object of the patented construction is defeated and the rigging is liable to be pulled out in a manner and for reasons well understood by those skilled in the art.

The object of my present invention is to provide novel draft-rigging possessing all the advantages of the patented construction, but capable of employment in connection with cars equipped with solid or filled bolsters.

A further object of the invention is to obviate the necessity for the employment of numerous keys connecting the draft-timbers and the filling-block and to bring the strain of the draft directly upon the bolster, which being connected to all of the ordinary carwheels distributes the strain in a manner to minimize the possibility of derangement.

A still further object of the invention is to improve the construction and mounting of the draft-spring and to dispose the latter in a metal pocket mounted in rear of the bolster and connected to the body of the car independently of the draft-beams.

To the accomplishment of the recited objects and others subordinate thereto the invention resides in that construction and arrangement of parts to be hereinafter described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In the said drawings, Figure 1 is a perspective view of the draft-rigging detached from the car structure and associated with the bodybolster. Fig. 2 is a bottom plan view of the draft-rigging and bolster attached to the carsills. Fig. 3 is a horizontal longitudinal section on the line 3 3 of Fig. 4. Fig. tis a vertical section on the'line {L 4 of Fig. 2. Fig. 5 is a transverse section on the line 5 5 of Fig. 3, and Fig. 6 is a transverse section on the line 6 6 of Fig. 3.

Like numerals of reference are employed to designate corresponding parts in the several views.

1, 2, 3, and 4 indicate the longitudinal sills of the car structure, and 5 the transverse end sill. To this structure, at a point removed from the sill 5, is bolted the body-bolster 6, which may be of solid form, but preferably comprises a flat upper member 7 and a lower member 8, having its ends bolted to the mem her 7 and having its middle portion spaced from the upper member by asteel filling 9, the width of which is preferably slightly less than that of the bolster. The elements of the bolster may be assembled in any desired 'for the plates.

manneras, for instance, by bolts passed through the sill 1 and 4 and the members 7 and 8 and secured by nuts, as shown, some-.

what longer bolts 11 being passed through the sills 2 and 3 and through the upper and lower bolster members and the filling-block 9. The filling-block 9 of the bolster is preferably of inverted-U shape, as shown in Fig. 4, its top wall being rigidly secured to the upper member 7 and the lower edges of its side walls being flanged for attachment to the lower member 8 of the bolster, it being noted, further, that this intermediate or filling block of the bolster is considerably narrower than the members 7 and 8.

The draft-timbers 12 and 13 are secured to the sills 2 and 3 by bolts 14 and have their rear ends reduced and extended between the members 7 and 8 to abut against the fillingblock 9 of the bolster. The front ends of the timbers are connected by a transverse bar 15, opposed to the front face of the end sill 5, and also by a stirrup 16, secured to the under sides of the timbers by bolts 17, certain of which serve as securing means for the bar 15. Between the rear ends of the draft-timbers 12 and 13 is interposed a filling-block 18, having its rear end abutted against the bolsterfilling and retained by bolts 19, passed transversely through the block and draft-timbers. One of the bolts 19 also passes through the folded rear extremities 20 of a pair of liningplates 21 and 22, seated against the opposed faces of the timbers 12 and 13 in advance of the block and provided with inturned top and bottom flanges 24 and 25, constituting guides for the follower-plate 26.

The opposed side faces of the block 18 and the timbers 12 and 13 are recessed, as shown, to accommodate the folded ends 20 of the lining-plates, so that said ends constitute guides which facilitate the insertion and removal of the block 18 and also serve as retaining means The follower-plate 26 is opposed to the rear end of the draw-bar 27 of the coupling-head 28, and between the plate 26 and a rail-plate 29, opposed to the front face of the block 18, are interposed a pair of concentrically-arranged buffer- springs 30 and 31, encircling a guide-bar 32, extending from the rear end of the draft-bar 27 and received within a socket 33, formed in the filling-block. It will now be obvious that the strain imposed upon the draw-bar by the impact of the coupling-heads of two cars will be sustained by the buffer- springs 30 and 31, backed by the filling-block 18, which is inturn backed by the body-bolster, so that while the strain is resisted in part by the draft-rigging and its connections to the sills the major portion of the strain is sustained by the bolster and is distributed, by reason of the connection of said bolster, with all of the longitudinal sills of the car structure.

To the sills 2 and 3 immediately in rear of the bolster is bolted the base-plate-34 of a metal, preferably steel, spring-pocket 35, the side walls 36 of which abut at theirfront ends against the tiller 9 of the bolster, and the lower edges of said walls 36 are turned inward to form flanges 37, which support and guide a follower-plate 38, opposed to the rear ends of the draft- springs 39, 40, 41, and 42, these springs being arranged in two sets, each comprising a pair of concentrically-arranged springs retaineolin place by guide- studs 43 and 44, extending from the follower-plate 38 and from the rail-plate 45, respectively. The rail-plate 45 is opposed to the front ends of the draft-springs and is backed by a block 46, interposed between the plate 45 and the filler 9 of the bolster. The side Walls 36 of the spring-pocket 35 are formed with longitudinal slots 47, which accommodate the rear cross-head 48, having its extremities passed through the slotted rear ends of a pair of longitudinally-disposed draft-bars 49, the slotted front ends of which similarly engage the opposite ends of the front cross-head 50,

bar 27 and accommodated by longitudinal slots 52 in the lining-plates 21 and 22 and by slots 53 in the draft-timbers. The opening for the king-bolt is indicated at 54.

When two cars are brought together for coupling, the draw-bar 27 will yield longitudinally against the resistance of the buflersprings 30 and 31, the strain being sustained, as has already been stated, by the bolster. When the cars have been coupled and the draft is applied to the coupling, the draw-bar will move out, carrying with it the crosshead 50, which through the medium of the draft-bars 49 advances the cross-head 48, the movement of which is opposed by the two sets of draft-springs located in the springpocket. When the draft is thus applied, the strain will come directly upon the bolster and its connection with the several sills, and danger of pulling out the rigging is thus avoided. It may also be noted in this connection that by opposing the cross-head 48 to a plurality of sets of concentric springs of great power the locomotive is enabled to start smoothly and without jar a car of greater tonnage than can ordinarily be handled in this manner.

If desired, the side walls 36 of the rear spring-pocket may be braced by a bolt 55, connecting a pair of lugs 56, pendent from the flanges 37, (see Fig. 6,) a spacing-sleeve 57 preferably surrounding the bolt between the lugs to prevent contraction of the pocket.

it is thought that from the foregoing the construction, operation, and many advantages of the improved draft-rigging for railwaycars will be clearly apparent to those skilled in the art without further description; but while the present embodiment of the invention is thought at this time to be preferable I I desire to reserve the right to effect such passed through an opening '51 in the drawchanges, modifications, and variations of the illustrated structure as may fall fairly within the scope of the protection prayed.
