SPECIFICATION forming part of Letters Patent No. 414,501, dated November 5, 1889.

Application filed February 18 1889. Serial llo. 300,330 (No model.)

To all whom it may concern.-

Be it known that 1, JOHN F. DAVEY, of Marlborough, in the count-y of Middlesex, State of lvlassachusetts, have invented a certain new and useful Improvement in Peg ging-Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art'or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of my improved pegging-machine; Fig. 2, an enlarged front elevation of the body proper; Fig. 3, a side elevation of the same; Fig. at, a front elevation of the awl-bar, the actuating-plate being removed; Fig. 5, a horizontal section.

taken on line :0 at: Fig. 6, a front elevation showing the cam, the awl-plate and hammer being removed; Fig. 7, an enlarged view illustrating certain details of construction; Fig. 8, a perspective View of a portion of the peg-strip; Fig. 9, an'enlarged elevation of the guide-plates removed, and Fig. a top plan view of the same,

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to that class of pegging-machines in which wooden pegs are employed; and it consists in certain novelfeat-u res, as hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body or standard of the machine, and B the body proper. The body A consists of a standard supported on legs b, (see Fig.1) and between 5 said legs is pivoted a treadle d, having a footpiece e and counterbalance-weight f. A vertical rod g is pivoted by its lower end to the treadle cl, said rod having upon its upper end a pegging-jack G, provided with spindle h 50 and toe-piece t'. The egging-jack may be of the ordinary form and construction common to machines of this class.

To the top of the body A is secured a forwardly-projecting arm in, at the outer end of which the body B, hereinafter described, is secured. A horizontally-arrangcd shaft m is journaled in said arm, and bears a clutch mechanism of any suitable construction connected with a treadle mechanism.

Upon the forward end of the shaft m is secured a disk i, (see Figs. 4 and 5,) which rotates in a corresponding opening in the head '0 of the arm 7r. The head 1) is dovetailed horizontally at to, (see Fig. 3,) and fitted to slide laterally on said head is a block 2, provided on its rear side with a dovetailed groove adapted to receive said dovetailed head. A horizontal]y-arranged gib 15 is disposed in the upper dovetail to between said head and block.

On the face of the disk 15 is secured a cam 16,which projects into a rectangular opening 17 in the block .2 (see Figs. 5 and 6,) and engages a stud 18 on an edge of said opening when the shaft revolves, thereby moving said block from right to left on said head when the shaft is in motion. An arm 19 projects laterally and rearwardly from one side of the block a, and a bolt 20 (see Fig. 5) passes through the end of said arm, and is secured in the inner end of a chamber 21 in the head 1). A coiled spring 22, disposed around the bolt 20, acts expansively against the arm 19 to return the block .2 after it has been moved by the cam 16, as described. The forward face of the block 2 is provided with a vertical dovetail groove 23, (see Fig. 5,) a plate 24L be ing fitted to slide vertically in said groove. (See Fig. 2.) A gib 135 is inserted in the groove 23 at one edge of said plate. A horizontally-arranged rectangular slot 25 (see Fig. 2) is formed in the plate 24, and fitted to slide in said slot there is a rectangular block 26, in which a stud 27, projecting from the face of the cam 16, revolves, the purpose of 5 said block being to move the plate "2% vertically as the cam-disk is rotated. A plate 28 (see Figs. 2 and 8) is secured by bolts 29 to the lower end of the plate 2%, said bolts passing through horizontal slots 30, whereby said we plate 28 may be laterally adjusted.

. there is an upwardly-proj ecting hollow standard D, and fitted to slide vertically in said standard there is a plunger-bar H, (see Figs. 2 and 4,) the lower portion of said bar being preferably rectangular in cross-section and moving in a vertical guide-slot in rear face of the vertical sliding plate 24. A stud projects laterally from the plunger-bar 11 into the path of the block 26, which engages said stud from below at each revolution of the cam and elevates the plunger. A vertically-arranged rod or hammer-bar 36 is secured by its upper end in clamping-plates 37 on the lower end of the plunger H. Two vertically-arranged guide- plates 40 and 41, Figs. 9 and 10, are bolted to a downwardlyprojecting arm 42, Fig. 6, on the block 2, said plates being provided with a vertical groove 43, in which the hammer-bar 36 works. An arm 44 projects vertically from the top of the standard D, Fig. 1, and is provided with a laterallyarranged head 45. spring 46, preferably constructed of two wooden bars 47 and 48, Fig. 1, has its free ends disposed between the head and top of the plunger H,'the purpose of said spring being to force the plunger downward after having been elevated by the block 26 engaging the stud 35, as described. A downwardlyprojeeting arm 70, Figs. 2 and 6, is bolted to one edge of the head i), and a vertically-an ranged cutting-blade 71 is secured to the lower end of said arm, said blade being adjustable longitudinally by means of a setscrew 72 and slot 73. The inner end of the blade works in a groove 74, Fig. 6, in the arm 42 of the sliding block 2. A cuttingblock 75, Fig. 6, is adj ustably secured to a block 76 on the lower end of the sliding block 2, said cutter-block'being provided with a vertical groove 7 7 ,which receives the edge of the blade 71 when the block 2 is moved by the cam 16.

A longitudinally-opening or peg box 78, Fig. 6,is formed in the arm 42, and is adapted to receive the wooden peg-strip P, Fig. 8, which is of the ordinary form employed in machines of this class. A guide-bar 79, Fig. 3, is disposed longitudinally above the pegs-lot 78, and is adjustable vertically on the arm 42 by means of a set-screw 80 and slot 81.

The hub 87 of the roll 83, Fig. 3, is extended vertically, and is journaled in a plate 88. On the upper end of said hubis secured a ratchet-wheel 89.

A gage to regulate the distance of the pegline from the edge of the shoe-sole is shown in detail in Fig. 7.

An arm 96, Fig. 3,projeots downward from the body of the machine-arm 7o at the rear of the feed mechanism. A key 97 is fitted to r0- tatein the arm 96, said key having a squared portion 98, Fig. 7, against which a spring 99 A V-shaped' in the arm 96 bears to prevent said key from being accidentally moved. 3, is fitted to slide on the lower end of the arm 96, said plate being provided with a vertical slot 101, through which the bit 102 of the key passes. A bar 103 is secured by its rear end to the plate 100, and projects under the arm 42, said bar sliding in a guide-loop 104 on the under side of said arm, and provided on its forward end with a guide-roll 105, disposed adjacent to the awl 32. The roll 105 is designed to engage the edge of the shoe-sole, and above said roll on the arm 42 there is secured a circular corrugated guide-plate 106, Figs. 3 and 6, which engages the bottom of the shoe-sole.

In the use of my improvement the shoe .is adjusted on the jack 0 in the usual manner, the bottom of the sole being held against the guide-plate 106 and its edge against the roll 105, which has been suitably adjusted by means of the key 97. Motion being imparted to the shaft m, the disk t, as viewed in Fig. 4, is .rotated from left to right, forcing the cam 16 into engagement with the block 18 and driving the sliding block 2' in the same direction. The peg-strip P, having been disposed in the opening 78 of the peg-box so that its outer end rests against the cutting-block 75, Fig. 6, is driven against the edge of the knife 71 by the movement of the block ,2, and a peg is thereby out vfrom said strip. As the cam 16 leaves the block 18 the spring 22 in the chamber 21, Fig. 5, of the headv acts expansively and returns the sliding block 2' to its original position. On the return motion of the'block z the feed mechanism is actuated and the peg-strip moved forward a COITQ: sponding distance or in position to have an: other peg cut therefrom. This forces the peg which has previously been formed from the strip into a slot (see Fig. 9) in the'guideplate 40, thus disposing it in the hammergroove 43 in position to be driven by said hammer. As the cam 16 continues to revolvein moving the block 2 laterally its pivoted block 26 engages the upper end of the awl-plate 24 and begins to elevate said plate, and nearly simultaneously therewith said block engages the stud 35 on the plunger H, elevating said plunger with the awl-plate. WVhen the block 26 leaves the stud 35, the spring 46, which has been compressedby the upward movement of the plunger, at once forces said plunger downward and causes the hammer-bar 36 to drive the peg in the groove 43 of the guide- plates 40 and 41 into the peg-hole previously made by the awl 32 in the shoe-sole. The continued rotation of the cam-disk now causes the block 26 to force the awl-plate 24 downward, following directly after the fall of the plunger and perforating the shoe-sole to receive another peg. The cam 16 again engages the block 18 and moves the sliding block .2 to the left, as before. It will be seen that this movement feeds the shoe in the same direction, it occurring while the awl is embedded therein. The

A plate 100, Fig.

shape oi. the cam 16 is so regulated that it releases or leaves the block 18 immediately the cam-block 26 has raised the aWl-plate sufliciently to withdraw the awl from the shoe, thereby permitting the spring 22 to return the sliding block 2, and thus dispose the plunger directly over the peg-hole in position to drive the peg which has been forced into the plate-groove 43by the feed mechanism at a prior movement of the sliding block 2, as described.

Instead of having the spring 46 act directly on the plunger, I provide said plunger with a percussion-sleeve 126 on its top, as shown in Fig. 4; but it may be omitted, if desired.

Having thus explained my invention, What I claim is 1. In a peg ing-machine', the gage-bar 103, provided with the horizontal roll 105, in combination with the slotted plate 100 and key 97, fitted to rotate in the machine-body and having the bit 102 working in the slot of said plate, substantially as described.

2. In a pegging-machineof the character described, the guide- plates 40 and 41, secured to the cutter-block and provided with the hammer-bar groove 43 and peg-slot 125, substantially as described.

3. In a pegging-machine, the plunger H,

adapted to be elevated bya crank on the driving-shaft and provided with the hammerbar 36, in combination with the guide-plates 10 and 41, provided with the groove 43 and peg-slot 125, and the spring 46, for depressing said plunger when released from. said crank, substantially as described.

4. In a e in machine the head a ro-.

vided with a peg-box, in combination with the block :4, fitted to slide on said head and provided with the cutter-block 77, the adj ustable knife 71, secured to said head, a cam on the driving-shaft for actuating said block, and a spring for returning the same, all being arranged to operate substantially as described.

5. In a pegging-machine, a head provided with a peg-box, a cam-actuated block sliding laterally on said head and provided with a vertical cutter-block, a longitudinally-adjustable knife on said head adapted to be engaged by said cutter-block, and a spring for returning the cam-block, substantially as described.
