TO- ALL WHOM IT MAY CONCERN: y

Y Beit known that I, WILLIAM R. LANDFEAR, of the ci-ty of Hartford, in the State of Connecticut, have invented certain new and useful. Improvements in Machines for. Pegging Boots and Slices; Iandido hereby-declaro the following to be a full and correct description of the same, reference beingphad to the accompanying draw-l ings, in whichi i Figure 1 is a perspective view of the hcadof thc machine complete, and Figures 2, 3, 4, 5, 6, 7, and 8,' are detailed viewsof various parts of, the machine. The same letter marks the same part wherever it occurs.

These improvements relate to the machine patentedby me September 13, 1864, which belongs ltothat 'class' of peggng machines in which .the boot or shoe is helduponia jack and pressed up. against a feeding device, whichl moves it under theawl and driver at-therproper speed forth@ sole to be perforated'and pegged in the well-known mode. They consist ir a more direct, secure, and convenient mode of feeding the peg-wood to the drivera'n improved device for holding the peg-wood during its passage through the machine to the driver, the application of an adjustable brake to control the movement of the feeding-sleeve, andia new device for guiding theiawl and driver, all as hereinafter more fully set forth.

v To enable others skilled in tire arttomnkc' and' use myimproredpeggingmachine, I will proceed to describe, its construction and operation,referringto the accompanying drawings by the letters of reference marked thereon, i

A2 marks the bed or frame to which the working parts are attached. This must b e placed on a pedestal of suitable height, and power applied either by means of a treadle worked by the operator, or from any suitable prime mover. Ay marks a pitnuan which connects therdrving powgr with the Agear-wheels B O,.the`latter of which is on the roerend of the main shaft 1)to which the fly-wheel E is attached. To the forward end of shaft i D is attached the crank-wheel F, (scc figs'. 2 and 5,) which is connected by the crank-pin G withr the sliding V descent of the bar.

block H, which reciprocates horizontally in slot I in the sliding cross-head J. The cross-head J has a vertical reciprocating motion in guides J1 J2, in obedience to the action of the block H driven by crank-pin Gr. To the cross-'head is attached thc owl-stock K, which carries the awl L, and rises and falls'with the head d. The driverstock M 'works throng-h a groove in the cross-head, and is independent in its movements of the head. It has a toe, N, projecting from it, whichis engaged oy block H as the crank revolves, and by which 'thelistock M is lifted. When, by the further revolution of the crank, the block H slips out from under the toe N, thcdriverstock M is impelled forcibly downwards by the action of Ythe spring S. The-driver O is attachedA to the lowerV end of stock M. P marks a hollow tube, called a chimney, in which the driver-stock M moves. The upper end of stock M has a screw-thread on it, and is receiued by the nut Q.y Washers/R intervenebetween the top of the chimney and the lower surface of thc nut Q. The object of this arrangement is to .adjust the stroke ofthe driver O, so that it shalll drive the pegs either even with the surface ofthe solo, orabove or below that surface, as may be required or preferred. The spiral spring S gives thc-downward impulse to the driver-bar when it is released from its engagement with block H. y

Attached to the rear side' of the cross-head J is a bent arm,- T, which performs several functions as the cross-head rises and falls. By means of two projections b b it operates lever y, (see figs. 1 and 3,) attached to i' which is pawl ,which impels the ratchet-wheel m on top of-feedroll d, by which the peg-woodf is fed into the machine. By meansV of pin c, (see iig. 1,) it operates the slotted lever V, which drives thefeed-sleevc or roll. To the bar Tis also attached the knife g, which severs the p egs from the pcg-wood, one peg'being out at cach 'The lever V has a-collar,'(see figs. 3 and 8,) which Vembraces the rear portion of the feeding-sleeve and moves loosely on it. The slot U in the arm of this lever is ofthe form. represented in fig. 1, so that at thelat-I I ter part of' the downward movement of vthe head J and bar T, and at the beginning of their upward movement, the lever V will be stationary, but will be raised at the last part of the upward movement of'bar T, and depressed I' at the beginning of its downward movement. A pawl, a, attached to the face of lever V, engages the ratchet W on the surface of the feed-sleeve, and drives that sleeve the distance between two teeth at every oscillation of the lever, the movementl taking place after the peg-hole has been'made, and just before the peg isdriven, the effect of the moiiement'being to bring the peg-hole under the driver to receive the peg.

The feeding-sleeve, (see figs. 1, 3, 7, and 8) ,is a hllow cylinder, which moves on aeylindrical axis, Z, projecting from the frame. The rear belt of this cylinder or sleeve is 'smooth to engage the brake D, and to receive the collar of lever Vhwhich moves freely on it, as before observed. The middle belt of its surface has the ratchet W cut upon it, which engages with pawl a on lever V, to drive the feed-sleeve by the movement of the latter. The front belt X of the surface of the sleeve is roughened, so that it will take hold of the sole of the boot or shoe, and'feed it along by friction as the sleevennoves on its axis.- To control the movement of the feed-sleeve, and prevent its turning backwards, when released' from contact with the awl and driver, I employ a brake, D', (see figs. 3, 7, and l8,) which is made to press with greater or less force, as may be required, against the rear belt of the surface of the feed-sleeve, which it` partly embraces. The pressure of the brake against the sleeve is regulated by the set-screw E', which can be tightened or loosened asroquired.

The peg-wood fis inserted in a long strip at the point indicated in figs. 1 and 8. A.' spi-ing, 7:, presses it forcibly against the roughenedroller d, operated by pawls c and l, andby the rotation of this roller it is driven through a passage in the body of the axis Z of the sleeve, (see .jgs; 6 and 7,) till it emerges in the square hole 7c, in which the driver O works(see figs. 5 and 8.) The peg-wood is held down by a bar, Al, placed on top ofit. This bar is itself held down by bolt B', which has a-'collar upon it, resting on the top of bar A1. A set-screw., C', fixes the bolt B at any desired point, (see iig. 6.)

On the frontend of axis Z are attached the plates G E', by means of screws passing through the holes z'vz', (see figs. 3, 5, and 8.) The two plates are grooved, as'shown, so that when brought. together and attached to the axis they form passagesj lc, for the awlLand driver O. The inner plate G has an oblong opening in it to allow of the Vexit of the peg from the passage 'in the axis Z to the driver-groove lc.

The operation is as follows: The boot or shoe to be pegged is placed on ajaclc' and brought up into contact with the roughened face of the feed-sleeve. `The awl and driver being both attheirhighest position, motion is imparted'to the machine, and the awl L descends, perforatcs the sole,l and is immetlately.\vithtlrawn. The feedslceve is then rotated by pawl a, and advances the shoe a distance equal to that between the awl and driver.

` This brings the aWl-liole directly under the driver. The space between the knife g and driver-hole c'is illed with pegs which have been severed from the strip of pcg-wood. By the, rotation of rollend, these pegs are successively presented under the driver in hole 7c. As soon as` the peghole comes directly under the driver, the toe N of the driver-stock slips from the top of block H, and the driver O descends and drives the peg into the hole prepared for it by the awl. The further rotation of the4 crank-wheel again drives the awl, and withdraws both awl and driver for a repetition o'f the operation.

It will be observed that by'the arrangement adopted in this machine, I avoidthe'inconvenient and curnbersome apparatus for the introduction of vthe pegs under the driver, which was adopted in my original machine, and which with slight modification is used in 'all the power machines with which I am acquaintedan apparatus on the exterior of the machine, exposed to injury, andin` which the distance which,intervenesbetween the knife andthe driver necessitates the moving alongof a large number of severed pegs. The greater their number, especially where, from imperfect cutting, there is the slightest variation in their s ize, the greater will be the tendency to uncertainty and want of precision in their presentation under the driver. By enlarging its axis,

` I not only givegreater power and certainty to the operation, but I secure a direct, convenient, protected, and

short passage for the severed pegs from the knife to the driver, rendering the machine more compact in structure, and less liable to get outof order.

In the foregoing descriptioml Vhave included some features common to this machine and the one formerly patented by me. Iihave also described and represented some 'features which have been added to the machine by David'Whittemore, and are of his invention. It was necessary to describe the machine as it at present exsts,rin order to'illustrate properly its construction and operation, and the relations ofmy improvements to the perfected machine. I do not, however, claimany other features as of my invention than those hereafter enumerated;

What I do claim, and desire to secure by Letters Patent, is

l. Passing the pegs severed from the peg-wood from the severing-knife to the'driving-bar, through a slot in l the axle of the feeding-sleeve, substantially in the manner and for the purpose described. V

2. The combination of the bar Al, bolt B', and set-screw C', arranged substantially as specified, for securely holding down the peg-Wood during its passage througl-themachne, as set forth.

3. The application of an adjustable brake to control the movement of the feeding-sleeve, in the manner described. l

4. .The face-plates F and 0^, arrangedas described, and forming grooves for the passage of the awl `and driver-in front of tl1e'feed-sleeve, as specified. I

The above specification of my said invention signed and witnessed at London, this second day of March,

W. R. LANDFEAR.
