To all whom it may concern.-

Be it known that I, ALONZO GRAFFAM, a citizen of the United States, residing at Dekalb, in the county of Dekalb and State of Illinois, have invented a certain new and useful Improvement in Pegging-Machinespvhioh' in vertical section and partly in elevation, of

the horn-post, horn, and anvil. Fig. 4 is a plan view of the anvil. Fig. 5 is a vertical section on the line 5 5 of Fig. 4. Fig. 6 is a detail view of the cam and bell-crank lever, which actuate the horn-post. Fig. 7 is a detail elevation of the pedal and spring device attached to the lower portion of the horn-post. Fig. Sis a vertical section of a shoe which has just been pegged.

It has heretofore been common during the operation of pegging shoes, to secure the outsole to the upper and the insole in pegged shoes, to leave the last in the shoe. The shoe was held on a'peggin'g-jack, which pressed the sole up firmly against the pegging mechan As wooden pegs cannot be inserted without the aid of a puncturing instrument, which makes a hole through the entire material resting upon the last, and as the thickness of the material varies at different parts of the sole, it is obvious that the awl, which must be longer than the thickest part of the sole, will pass into the last more or less where the sole is thinner, as in the shank particularly. Inasmuch as itis also impracticable to use more than one width of the wooden strip from which the pegs are out just before being driven and inasmuch as the pegs must be sufficiently long to bring their points at least flush with the inner surface of the sole at all points, it is apparent that over the thinner portions of the sole the points of the pegs will project beyond the inner surface thereof, and will thus be driven more or less into the last. This constant pricking of the last by the awl and the driving of pegs thereinto soon deteriorates it and in a short time renders it useless, causing great expense to the manufacturer in renewing his supply of lasts. Moreover, the use of the last is the source of frequent breakage of awls and other parts, and the cost of the labor employed in drawing the last from the shoe after it has been fastened to the inner solo by perhaps a hundred pegs projecting into the su rface thereof is very considerable. To avoid these sources of loss and diminish the cost of pegging and the labor requisite thereto, I have devised a machine in which a slotted anvil is constantly presented to the inner surface of the insole just beneath that point Where the puncturing and hammering mechanism of the machine is at work upon the outsole.

'While I find that the broad idea of a slotted anvil into which the awl passes in puncturing the sole and which it traverses in feeding the sole is not novel, yet certain details and features of the construction whereby such an pegs, thus bringing the part of the material that was to receive the peg at a distance radially from the axis of the horn equal to the length of the feed. Thus the work was to be pierced by the awl at a point coaxial with the horn, and the peg was to be driven ata point non-coincident with the axis of the horn, requiring that the tip or substantially circular anvil in the end of the horn should be of a radius substantially greater than the length of the feed, thereby precluding the/entrance of the horn far enough into the toe portion of the shoe to drive the pegs properly.

In the work-support forming the subject of this invention the work {supporting anvil, which is supported in the end of the horn, but restrained from rotation therewith with relation to the peg-drivin g mechanism,isprovided with an awl-passage extending vertically into the same, but having its operative portionit. e. ,the part through which theawl passes d n ring its feeding movementwith its ends noncoincident with the axis, being'set to one side of the axis a distance about equal to one-half the normal feed or'space between the consecutive pegs to be driven in the material. The" awl-hole isthus formed in the material at apoint non-coincident with the axis of the horn, and the feed takes place, carrying said material so that the awl-hole' formedtherei n passes across the center'of the horn and at the end ofthe feed movement is non-coinci-- dent therewith on the other side of the axis from the pointat which the awl-hole was made, so that the diameter instead of the radius of the button, as heretofore, need be only large enough to accommodate the feed of the material and afford a support therefor adjacent to the point in the material at which the awl penetrates and at which the peg is driven. Thus, other things being equal, the button having an awl-passage with its operative portion beginning and ending non-coincidently with theaxis of the horn in accordance with be made sntiiciently small to peg properlyin any required portion of a boot or shoe.

In a machine having an awl-feed, in which my present invention is shown as embodied, I make the slot in the anvil of a sufficient depth to accommodate the awl and pegs, and while the non-coincident location of the ends of the operative portion of my slot would be embodied in a slot which began at one side of the center of the axis of the horn and terminated at the other side of said axis, yet I preferably continue said slot in both directions from the center, so that it forms a channel completely through the anvil, thus permitting the pegs to pass freely out of one end of the slot after being pegged, and if'it is desired to retrace any portion the slot being open at both ends readily permits this.

Referring to the drawings by letter, A represents the main frame of my pegging-machine. B B are the loose and driving pulleys, and G the balance-wheel, mounted upon and adapted to revolve the shaft D. E is a spring device adapted to actuate the peggin g mechanism. F is the guide or gage against which the edge of the sole bears while being pegged. G represents the awl, and H the hammering mechanism. These parts are all of any preferred construction, and being well known in the art require no further description here.

The shaft D carries a cam-surface I, upon which travels a roller J, carried upon one arm of the bell-crank lever J, to the other arm of which is pivoted the upper end of the connecting-rod K. The lower end of the rod K is pivotally connected to one end of the pedallever L, pivoted as at l. The other end of the "posed'horizontal' brackets A andA pedal-lever. L is provided with a pedal L. Mid'waybetween the'pedal L'andthe pivotal mounting of thelever at 1 there is pivotally attached to the said lever, as at 1 the lower end of the horn-post, later described.

The frame A is provided with two superim- The VGltiCfilhOlIl-POST) Mis loosely mounted int-he said brackets, so as to be free to move vertically therein,the said brackets forming guides for such movement. The lower portion of the .horn-post is reduced in section to form a shank M, and the upper end of this shank M is screw-threaded, as at m. Upon this screwthreadedpart is mounted a collar on, which can thus be vertically adjusted upon the shank.' Th61OW6D'Of the two brackets A. is provided with 'the stayerods N, depending therefrom, which support at 'theirlower ends a collar N, surrounding the horn-post, which is free to inovevertically.therein. Between the collar in and the collar Nand surrounding the shank of the horn-post is mounted a compression-spring O. The lower end of the shank M is pivotally connected to the pedallever at P, as herein-above described.

Upon the upper'portionjM of; the horn-post M is mounted thelslee've P, resting .upon the flange m and Iadaptedto rotate loosely upon the horn-post. The sleeve P is'provided with the bracket projection P, in which. is rigidly the extremity of the said branchQismount- 1 ed the vertical pivot R, which carries at its upper end the slotted anvil S, which is.preferably formed of the base portion Sand the two vertical walls or flanges S forming an intermediate space or slot S To the .lower end of the pivot R issecured the small bevelpinion T, meshing withthe pinion T, carried upon the shaft T which is mounted in bearingsupon. the branch Q. The lower end of the shaft T is connected with a vertical shaft U, mounted in brackets attached to the horn Q through the universal joint U. The lower end of the shaftU is provided with a small bevel-pinion it, which through the intermediate bevel-pinions 1L2 and u meshes with the bevel-gearV, which is rigidly secured upon the extreme upper end of the horn-post M.

For the purpose of throwing themachine into and out of operation Iemploy any suitable form of clutch mechanism Y, operated by a pedallever Y, with which it is connected in any suitable manner. The operation of these parts in connection withthe pegging of a shoe is as follows: The shoe is first lasted, the outer sole temporarily tacked in place, then the last is withdrawn. The shoe is then placed upon the horn in such wise that the slotted anvil bears against the inner surface of the sole at the point where it is desired to drive the-first'peg. The-machine is then started into operation by the pedal-and-clutch mechanism described. The awl descends,-

punctures the sole, and as it rises feeds the shoe'forward, so that the hole thus made is brought under the peg and peg-driving mechanism. As seen in Fig. 1, the awl as it descends is non-coincident with the axis of rotation of the horn, and as it feeds it crosses said axis, so that when it risesit is non-coincident on the other side. pegs X X thus come through the inner surface of the sole they form a row of projections which pass rearwardly through the slot in the anvil as the shoe is fed forward. The anvil is kept inrthe same position relative to the machine as a whole and to the pegging mechanism by means of the gearing T T, &c., hereinabove described. WVhen the horn is rotated to change the direction of the pegging with reference to the sole of the shoe, the anvil, although it rotates 011 the horn, retains the same position with regard to the rest of the machine, so that the pegs still may pass' rearwardly out of the slot.

It is not necessary to have the slot extend completely through the anvil. If it extends from the point at which the awl and peg enter the slot to the point at which the peg ends pass out of the slot rearwardly, the device is operative for most purposes. It is preferable, however, to have the slot extend completely through the anvil, as it is frequently desirable to -retrace the anvils path along the inside of the sole in order to repeg portions where there has been some defect in the first pegging. This could not be done if only one end of the slot were closed.

The cam I, through its connections with the horn-post, intermittently releases the upward pressure upon the said post each time that the shoe is fed forward and materially facilitates the feeding process. The spring device used in connection therewith holds the anvil and shoe firmly up to their work and yet at the same time yieldingly, so as to take ofi much of the jar from the driving of the pegs.

When the pedal L is depressed bythe foot, the horn is thrown still farther down and the shoe may be removed, the spring again restoring the anvil and horn to their normal positions.

I do not limit myself to the specific devices shown and described, which may be modified in many details without departing from the principles of my invention; nor do I restrict my invention to a combination of all the features'thereof; but
