- 7 Claims.

This invention. relates. to wood working hand power. tools.

The wood working hand. power tools of my invention. are. adapted. to. be used with either an electrichanddrill.or.a power driven, shaft. The toolsgmay. also beused asan. accessory for drill Dresses, and/or. lathes-by using. the cutter tools only asdescri'bed. more fully hereinafter.

Thewood working hand power tools are ideally adapted as. a. small.v and inexpensive shaper for thehome workshop or amanual training school workshop bnt,.of '-course, the tools may-be usedas a complement. to commercial wood. working plants...

Inperforming woodworking operations which involve the use. of. a power driven cutter, or the likeheretoforea. number of such individual tools werev provided for, edging straight-edged boards and outside, curves; for puttinga bead around a One-half inch hole; for shaping anedge on wood from one-eighthv inch thick totwo and one-half inches. thick, both. soft and, hard woods; for cutting. beads, flutes and other designs. of various widths up to one. inch, and forming tongue and grooves as well as to out screen. molding. Furthermore, in these individual. hand power tools, known prior tomy invention, itwas quite impossible, by. the use of any one tool; to cuta relatively wide pattern in the Wood or to combine a combinationof cuts in the. wood. Moreover, in these prior tools, there is provided one or more of. such: tools for making shallow mortise joints by useof tongue and groove cutters.

With. my wood working hand power tool, which includes readily interchangeable. arbors having cutting surfaces thereon, by providing I 7 ably associated with wood Working hand.

power tool. The arbor. on shaft speed of 2000- be increased or decreased over the speedmenshaft. is anti-frictionally mounted inthat. hand different interchangeable arborsf to be power I driven, I can. perform all of theaforesaid wood workingoperations, and other wood working operations by the use of the single tool.

One of the features of my wood working hand power. tool is that it is indeed very simple and provides for a wide range and flexibility of wood working operations. The tool consists of only four; major parts or component elements; name- 13; a relatively small diameter cutting arbor which is a shaft approximately four inches long with. the cutter substantially intermediate the ends thereof andpreferably integral therewith, two adjustable guidesmounted on the said shaft in spaced relationship at either side of the cutter and; a ba1l' bearing hand grip piecewhich enables the user to. gripthe same inthe operation of the. tool and in, performing; the various wood working operations. aforesaid.

My difierent cutter designs are interchangerality. of individual arbors. or shafts carrying tioned and produce satisfactory results.

My wood working hand power toolis of the two-handed type; namely, that aknob or. hand grip piece is grippedin one hand andv thearbor grip piece at one end thereof andv the other end of. the arbor shaft has. attachedthereto an electric handdrill or the endofia power driven.fiex.- ible shaft, there. being a. driving. connection, or

cou ling between. either. the. hand. drill. and the.

end ofthe arbor or. adrivin co nection, betw i. the end of. the power. drivenfiexible. shaft and the arbor.

With the. foregoing inmind, i.t is, therefore, an object of. myinvention, to provide a relative y simple and inexpensive wood working hand power. tool for performing. a. series. of. different wood working cutting or. similar. operations.

Another-object of my inventionjsto providea "relatively simple and inexpensivewood working hand power tool consisting of a minimum number of parts andyet'being durableandcapable of long use. in. performing various. wood working cutting and similar operations.

Another object of. my invention is to providea woodworking hand power. tool whereby a plurality of individualarbors or shafts. carrying out.- ters, thereon intermediate, the. ends thereof are readily connected with and disconnected from a- 'hand grip pieceor similar, elementatv one endv of the arbor and a power driving means at the-other end thereof.

Another object of my invention-is to provide a wood workin hand power toolv whereby a pl cutters thereon intermediate the endsthereof. are readily connected with and. disconnected from a hand grip piece or similar element, at oneend of the arbor and a. power driving means atthe other end thereof,.and'withsuitableguide means intermediate the; ends of the arbor and ateither side of the cutter or other wood working means and which guide meansserveto enable the tool as a whole, including the cutter on the arbor, to be drawn over the worker to-be held. stationary and move theworkrelative to the. rotating cutter.

Another object, of my inventionis; to provide.

a readily and quickly. disoonnectible; arbor; cutter from-asuitablehand-piece.

Another object of my invention is to provide a readily disconnectible connection between an arbor carrying a cutter thereon and a hand grip piece that is at one end of the arbor and a readily disconnectible power driving and operating means at the other end. of the arbor.

Another object of my invention is to provide a wood working hand power tool including an elongated shaft or arbor with a cutter intermediate its ends and a hand gripping means for one hand of the operator at one end of the arbor and a disconnectible power driven means at the other end of the arbor which is gripped and held in the other hand of the operator.

Another object of my invention is to provide a wood working hand power tool including an elongated shaft or arbor with a cutter intermediate its ends and a hand gripping meansfor one hand of the operator at one end of the arbor and a disconnectible power driven means at the other end of the arbor which is gripped and held in the other hand of the operator, and with a cutter on the arbor substantially intermediate its ends and with suitable guide means fixed to the arbor in spaced relation to each other and to engage on opposite sides of the work so as to guide the tool relative to the work or the work relative to the tool when the work is being operated'on by the said cutter.

With the above and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportions, and minor details of construction, within the scope of the claims, may be resorted to without departing from the'spirit or sacrificing any of the advantages of the invention.

main elements; namely, the hand grip piece or knob l3; the slide locking means M carried by the hand grip piece; the arbor l5, the cutter l6 mounted intermediate the ends thereof and the similarly shaped guides or guide means I! and I8 fixed to the arbor shaft at opposite sides of the cutter l6.

More specifically, the hand grip piece I3 of the wood working hand power tool consists of a preferably circular and rounded hand gripping portion I9 laterally projecting from which there is a concave medial portion 20 of less diameter than the gripping portion of the hand grip piece, and the end of this hand grip piece 2| is substantially circular in outline and is cut out as at 22 to provide a recess wherein there is disposed a suitable anti-friction bearing unit 23 consisting of inner and- outer races 24 and 25 respectively between which the balls 26 are disposed and held in proper relationship to the said races.

A cover or closure plate 21, which is more or less flat and of the same size as the end of the hand piece wherein the ball race is positioned, serves to maintain the ball race in the recess in the end of the hand grip piece and is attached thereto by several screws 28. This closure, which is preferably of sheet metal or, of course, may be cast, is provided with an embossed or struck out guide forming portion 29 which provides a recess 30 between an inner face portion of the closure and the outer diametrically oppositely disposed portions of the end of the hand piece and the anti-friction bearing mounted therein.

The slide locking means M, which is in the form of an elongated and substantially rectangularly shaped flat metal strip and provided intermediate its ends with a keyhole slot 32, is flanged over at its respective ends 33 and 34, the flanges extending substantially at a right angle thereto. This slide locking means is disposed in the recess or chamber 30 provided between the closure 2? and the end of the hand grip piece and is adapted to slide within predetermined limits within that chamber or passageway and is maintained therein due to the turned over ends 33'and 34.

The arbor l5 with the cutter it between its ends, is in the form of an elongated shaft. Adjacent one end thereof, there is provided a circumferential groove 35, which groove is in a plane so as to be disposed in the key hole slot 32 in the slide lock [4 and, when the small upper portion 36 of the key hole slot is disposed in the circumferential groove 35 adjacent the end of the arbor, the latter is securely rotatably locked in its association with the hand grip piece l3, and release of the arbor from the hand grip piece is effected by simply pressing on the flanged portion 34, as seen in Fig. l, to move the enlarged portion 3'! of the key hole slot in axial relationship with the arbor and which arbor can then be withdrawn totally from the hand grip piece and, of course, is thereby disassociated therefrom. I a

The guide means I! and I8, which are identical in formation, each is in the form of a collar consisting of a hub portion 38 which is p erably circular in outline, and a disc-like flange 39 integral with the hub having opposed face portions F which may be plane surfaced or slight 1y crowned. The hub portions of the guide means are fixed to the arbor by means of headless and socketed screws 40 and, of course, are adjustable axially along the length of the arbor and capable of being aflixed thereto by means of the said screws so that work of different widths may be ascends disposed between these guides, and intermediate such guides; there is positioned the cutter: I6 that is" carried by and preferably integral with the arbor: or shaft;

The other-end of the arbor or shaft 41 has drivingly attachedor connected therewith a suita-bleelectric hand dril1'42 and which hand drill is of the conventional type including the chuckinghead thereof and, of course, the hand drill is electrically motor driven or otherwise motivated. In lieu'of the electric handdrill 42-, I'may use, ,and do, in some instances; theend'of a power driven flexible shaft that grips the end portion 4 lofthe'arbor.

Indicated in pale lines, as at B, there is a small wrench having a right-angular'polygonal portion 44 that extends into the polygonal openings in the headless set-screws 40 and allows for quick adjustment or movement of the guides I! and I 8"on' the arbor or cutter shaft.

In Fig. 11, I have shown thearbo'r l having.

' is of the two-handed type; namely, that theoperatorgrips the hand grip piece I3 in onehand, elther;the right or left, andholds the electrically driven hand'drill in the other hand, or the end of a power driven flexible shaft is to be held in that hand, and the cut of the wood W is started on the far end of the work and gradually drawn forward toward the operator. Thus, it will be seen that, by providing for the ready interchangeability of the arbor or shaft with the different cutters intermediate the ends thereof, and the adjustable guides, the wood working hand power tool is indeed very flexible in its operations and functions with regard to woodwork or similar material to be operated on.

In examining the drawings Figs. 1 and 5 it will be noted that the integral cutter and arbor serve to limit the depth of the cut into the wood. By utilizing the integral arbor and cutter no definite stop means or any other means for limiting the depth of cut into the wood is required. In other words, due to the particular formation of the arbor and cutter in each instance either the arbor in part or some other point in the cutter itself limits the depth of cut into the wood, and the depth of cut into the wood is determined by the particular design and construction of each individual cutter, note the cutters in Figs. 10 and 11 of the drawings.
