To nr/Z wir/071e t may concern.

Be it known that we, ARTHUR G. LEONARD, residing at Chicago, in the county of Cook, and ALONZO GRAFFAM and BYRON R. WOL- GOTT, residing at De Kalb, in the county of De Kalb, State of Illinois, have invented a certain new and useful Improvement in Shoe- Pegging Machines, which is fully set forth in the following specification, reference being Io had to the accompanyingdrawings,in which- Figure lis a side elevation ofa machine with our improvements attached. Fig. 2 is a vertical section on the line 2 2 of Fig. l. Fig. 3 is a front elevation'of the upper portion of the machine. Eig. 4E is a section on the line 4 -l of Fig. l. Eig. 5 is a section on the line 5 5 of Fig. l. Fig. 6 is a plan view of the horn-tip with the horn-cap removed, and Fig. 7 is a detail plan View of the horn-cap. zo Our invention relatesto shoe-pegging machines, and more particularly to mechanism adapted to cut off the projecting points of the pegs as fast as the said pegs are driven through the sole. z5 Referring to the drawings by letter, A represents the general framework of the machine, consisting particularly of a standard mounted upon the legs A and provided with the projecting brackets A2 and A3, one above the go other. lnsuitable bearings in the upper part of the frame is journaled the main drivingshaft B. Upon the rear end of the said shaft are loosely mounted the pulleys B and B2, the one being a driving-pulley and the other ;5 free to revolve on the shaft at all times. The said shaft further carries a fly-wheel B3 and a clutch mechanism B4, adapted to throw the shaft in clutch with the driving-pulley B'. The clutch B4 is operated by the lever B5, to

1.o the lower end of which is attached the connecting-rod BG, connecting the said lever with the treadle B7. A spring B3, connected with the clutch-lever B5, normally holds the clutch out of operation. By depressing the treadle .5 B7 the clutch is actuated and the shaft B revolves.

Upon the shaft B, preferably between the driving mechanism in the rear and the pegging mechanism in the front of the machine,

there is keyed a cam-wheel C, provided upon 5o one of its side surfaces with a cam-groove C, which is circular throughout except at one point of offset C2. Below the said cam-wheel there is pivoted to the framework of the m'achine at one end a short lever D. Near its free end the saidlever carries an upwardlyextending arm D/, provided with a horizontal pin d, which projects within the cam-groove C'. The said lever D is further provided near its free end with aseries of perfor-ations 6o d. A connecting-rod D2, which is preferably adjustable in length, as at d2, is at one end pivoted to the leverD by one of the said perforations d. At its lower end the said connecting-rod is pivoted to one arm of a bellcrank lever D3. To the other arm of the said lever, which is pivotally mounted in the framework of the machine, is pivoted one end of a connecting-rod D4. The remaining end of the said rod is pivoted to one arm of a sec- 7o ond bell-crank lever D5, which is mounted as hereinafter described.

In suitable bearings formed in the brackets A2 and As is mounted a vertical horn-post E, which is hollow throughout its length, as at e, and is free both. to reciprocate vertically and to rotate in its said bearings. The bracket Azupon each side carries a hook or projection e', to which is attached the upper end of a coiled contracting-spring E. The 8o lower end of each spring is attached to a Second hook e2, carried by a sleeve e3, whichsurrounds the lower end of the horn-post and bears against the collar e4, rigidly secured to the horn-post. The actions ofthe springs E are thus normally to hold the horn-post up, with the collar e4 abutting against the bracket A3. The horn is at the same time free to rotate in its bearings. A yoke E2 is pivotally' attached at its upper bifurcated end to the 9o sleeve es. The lower end of the said yoke is pivoted to the treadle E3. A perforated cap e5 is secured to the lower end of the horn-post. The sleeve e3 bears against the said cap when the sleeve is depressed. The operation of ythe springs E is to hold the horn-post, and

through it the work, against the presser-foot of the machine. By actuation of the treadle E3 the horn-post is depressed. To the sleeve l e3 finally there is secured or formed integral therewith the bracket E, in which is pivotally mounted the bell-crank lever D5, hereinv above referred to.

Upon the Lipper end of the horn-post is mounted the horn F. This horn comprises a collar F, adapted to be secured to the upper end of the post, an upright portion F2, and a diagonally-disposed portion F3, curved and terminating in an approximately horizontal tip F4, the three parts F2, F3, and F4 being hollow. The upper surface of the horn is provided with a longitudinal aperture f to permit access to the interior of the horn. This aperture is closed by the horn-cap F3, which is curved to fit the tip of the horn and is provided with a small circularaperture f' at its extreme upper end. In the under surface of the tip of the horn F4 there is provided a second apertnrefz, directly underlying f. On the inner wall of the horn and near the attachment thereof to the horn-post a lever G, comprising the two arms G and G2, is pivotally mounted upon the pin g. The arm G of the lever projects over the central aperture e of the horn-post and is provided with two perforated ears g', which inclose and are pivotally connected to the ends of a cylindrical crosspin g3. The said cross-pin is mounted so as to revolve in a horizontal plane upon the upper end of the vertical connecting-rod G3, but is prevented from vertical movement upon the said connecting-rod by the nuts g3 above and gl below, by which the position of the cross-pin can be adjusted up and down on the said rod. The connecting-rod G3 extends down through the longitudinal aperture e of the horn-post and is pivotally connected at its lower end to the remaining arm of the bell-crank lever D3.

The arm G2 of the lever G extends within the hollow of the horn. Within this hollow is mounted an upright rodH, bent diagonally at H to follow the direction of the horn, but terminating short of the horn-tip. To the upper end of the rod H is pivoted the end of a shank H3, to the upper end of which is secured a knife-blade H3. This blade is upon its upper surface curved to correspond with the lower surface of the horn-cap and is provided with the cuttingr edge h, terminating just short of the aperture f of the horn-cap.

The construction just described, in which a removable horn-cap is employed in connection with a knife shaped to coperate therewith and mounted on a shank pivotally connected to the reciprocating operating-rod H, is one of much importance in the practical operation of these peg-cutting devices, inasmuch as thereby the knife can be readily gotten out for sharpening by simply removing the horn cap and swinging the knife and shank outward, with the aperture normally covered by the horn'cap. This feature of construction can of course be applied to any shape of horn and is not limited to the particular form shown and described.

I represents a portion of a bootsole in the I process of being pegged, t' the pegs already driven, and t" the projecting point which it is desired to cut from the inside of the sole.

As the cam-wheel C revolves in the operation of the machine at determined intervals, a short reciprocating movement iscommunicated to the connecting-rod D2, and through the said rod the bell-crank levers D3 and D3 and the connecting-rod D4 to the rod G3. r1he lever G is thus actuated, and through the rod H the knife-blade H3 isat the said determined intervals thrust forward across the under side of the aperturefl of the horn-cap, severing oif the downwardly-projecting peg-point i',

the said point dropping out through the aperturefz. As the bracket E4 is mounted upon and moves up and down with the horn-post when the same is depressed and released, the knife and its connections are little, if at all, affected by the vertical movements of the horn-post and the horn. By pivoting the connecting-rod D2 at a diferent perforation d by altering the length of the said connectingrod, as at d3, or by adjusting the cross-pin g3 through the nuts g3 and g4 the extent and the limits of the movement of the knife may be adjusted with great nicety. Finally, from the connection of the lever G with the rod G3 it is obvious that the operation of the knifeactuating mechanism will not be affected by the rotation of the horn and the horn-post.

In the operation of this mechanism the head K slides from right to left, as shown in Figs. 3 and 8 of the drawings, the plate K2 then rises, the head K slides from left to right, and the plate K2 again descends, this customary cycle of movements being effected by the mechanism shown, which is of the ordinary construction. As the awl S, which is rigidly adjusted in the head K, descends it penetrates the outsole, upper, and insole immediately adjacent the edge of the aperture f', thc particular portion of the edge being determined by the angle at which the horn stands. The head then moves in the feeding direction from right to left, and the awl S, moving diametrically across the aperture f carries with it the work until the awl is adjacent to the opposite portion of the edge of the aperture, which is of a width equal to the length of the feed desired plus the diameter of the awl or peg. The head K now rising carries with it the awl S, leaving the work with the puncture adjacent to the edge of the aperture f. The head now moving from left to right carries the awl S back to the starting position and brings the hammer R and the perforation p' of the peg-box cap directly over the puncture. As the head K now starts to descend the hammer R, which has been putting the drivingspring under tension as the head ascended, is released, and it descends quickly in advance of the head K and the awl S and drives the peg through the hole punched in the work. Immediately after the peg has been driven and before the awl S has completed its descent the knife H3 is shot across the under side of the aperture f', severing the projecting end of the peg, after which the cycle of operations is repeated.

It will be apparent that by punching the hole for the peg adjacent the edge of the aperture f and then feeding it across to the opposite edge of the aperture and driving the peg in that position the work is quite thoroughly supported, on one side at least, during both the punching and driving operations, which if they occurred in the center of the aperture or at any distance from the edge thereof would tend to depress the insole and upper, especially if the aperture were large enough to permit of the awl moving therein to feed the work, as is the case with our construction and which is the most satisfactory feed. By our construction permitting the punching of the hole and the driving of the peg adjacent to the edge of the aperture f and feeding the work by moving the awl diametrically across the aperture we are enabled to not only reduce the size of the aperture as compared with a similar one in which the awl-feed is radial-t'. e., from edge to center-but we are enabled to secure the support of the edge of the aperture not only for the punching of the hole, but for the driving of the peg, which was not possible with the radial feed. Moreover, the same advantage can be secured with the same sized aperture when shorter feeds are used, inasmuch as when such feeds are employed all that is necessary is to adjust the mechanism so that the feed instead of being strictly across the diameter of the circular aperture will be on a secant which of course will be equal to the length of the feed plus the diameter of the peg, by this adjustment securing the same support as for the strictly diametrical feed. By the use of this construction we are enabled to employ the best form of an awl-feed without increasing the size of the horn tip or aperture therein so as to render the device impractical.

While we have shown our invention as embodied in the form which we at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modifications and that we do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the art.
