TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. W. SOULE, of Boston, in the county ofSuolk, and State of Massachusetts, have' invented certain new and useful Improvements in Pegging-Machincs; and Ido hereby declare that the follow' ing, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suiiicient to enable thoseskilled in the art to practise it.

My invention relates particularly lto that 'class of lboot'and shoe-pegging machinery in which the work is yintermittently fed by a wheel (and not by the awl) to the'action of the awl and peg-driving mechanism, and my improvements have direct reference to the manner of cutting thepeg from the strip of peg-wood, to the arrangef ment of mechanism for feeding the peg-wood, to the manner of pressing the peg-wood up against the feed-wheel,

and to the arrangement of the gauge-mechanism for determining the distance from the edge of the sole at which each line of the pegs Ashall be inserted.

The drawings represent the main parts of a pegging-machine, of that class above referred to, embodying, e my improvements. The jack or boot-sustaining mechanism is not shown, and the shoe-feeding wheel is not shown, as their construction and arrangement are well known.

A shows agplan of tbe machine.

B is a sideelevation.

C is a front end view, the front cap-plate being removed.

D is a reversed plan of the head of the machine.

a denotes the frame of the machine,at the front end of which is the head b, upon and in which are arranged the peg-cutting and feeding mechanism, and the awl and peg-driving mechanism.

c denotes a vertical shaft, having. at or near its lower end. a serrated or tobthed surface, d, projecting slightly in front of a wall, e, which, with an opposite surface,forms a peggroove,f, through which thepeg-wood is fed to the action ofthe peg-cutter and peg-driveiythe peg-driver g working vertically infront of and in direct line with this slot.

The pcg-wood is held up to the surface ofthe feed-wheel d by a leaf-spring, t, which is secured at one end to a shoulder, z', by a screw, j, as seena't B. i

By means of an adjusting-screw, k, the stress of the spring upon the peg-wood to press it against the feedwheel maybe adjusted, as may be desirable, to suit the conditions of the various qualities ofpeg-wood which may,be used,v such as thick' or thin, wet or dry, soft or hard peg-wood, either kind being fed perfectly by the feed-whecl, by simply adjusting the pressure of the wood against the feed-teeth by means of the spring and its 4 adjusting-screw.

The feed-shaft has nt its top a ratchet-wheel, Z, which has an intermittent rotative movement vimparted to it by means of a spring-pawl, m,'and to give this pawl a direct forward-and-backwar-d movement, I joint it to thev end of a l1orizontnlly-reciprocating slide-bar, n, which works between ways or guides 0, and receives motion from a cam, p, on the driving-shaft q, through a lever, r, and connecting-rod, s.

The lever r has a slot, t, through which the screw-pin u of the connecting-rod S'passes, and by moving the pin up or down in the slot, the amount of throw of the slide may be regulated, as will be readily understood, so that the feed of the peg-wood may be adjusted, as circumstances may require, a detaining-pawl, s', preventing back movement of the ratchet, when't-he slide-bar o and its pawl m move back.

Herctofore, in this class of machines, the practice hasbeen to place the pcg-cuttng knife at some distance back of the peg-driver, or at such distance as to have-a number of cut pegs between the driver and the cutter at all times. 'lhis is objectionable, because, if the peg-wood does not happen to eiactly fit the throat or channel through which the wood passes, the pegs are liable to slip from position and to clog in the channel, thereby machine, 'so as to render it necessary to remove the cap to clear causing had pegghig, and often obstructingthe away the broken or jammedup pegs. v

To obviate this, I place the cutter v in a plane, one peg behind the rear side ofthe peg-driver, so that only one severed peg shall be in the machine at once, and this one in position to be fed beneath the driver, or into the vertical peg-groove ofthe cap e', at the next forward feed-movement of thepeg-wood.

The cutter is shown as'xed to a cutter-plate or stock, w, which is hung upon a crank-pin, 2:, of a shaft, y, y

downward movement of'an arm, z, carrying the cutter down and forward against and through the peg-wood, and upward movement ofthe arm carrying'the'knife .up and back out of the path of the peg-Wood.

After the peg has been driven, and the peg-driver has risen, the peg-wood is fed forward, bringing the peg, cut off of its front end, into the vertical peg-hole in the cap v directly beneath the peg-driver. The arm, z,

being then thrown down, and the peg-driver descending at the same time, the peg will be driven, and the cutter will move forward and cut oif the front end of the peg-wood, thus forming the next peg, the position of the relative parts being as shown in horizontal section at E. 4

Thus it will be seen that the wood, being leftuneut until by its next forward movement the peg is te be fed beneath the driver, cannot, of course, clog, as when several cut pegs lie together in line.

a2 denotes the gauge-wheel, the edge of thesole being presented against the front .edge of this wheel as the shoe is fed along.

The wheel turns on a pin projecting from a slide, b2, which plays between guides c2.

The wheel is held normally in position by a spring, d2, and topi-ess the boot out to peg nearer to the edge, as the boot is fed forward, lever e2 is used, this lever having an incline, f2, which, being pressed up by depressing the handle y2, throws out the wheel, and thus brings the edge of the sole nearer to the path of the peg-driver.

To permanently adjust the normal position of the gauge-wheel, relatively to the path of the peg-driver, I mount the slide b2 upon a plate, h2, which is provided with slots z?, through which the fastening-screws k2 extend. By loosening these screws, the plate may be slid forward or back, and then fastened by tightening the screws, so as to x the distance of the normal peg-driving line from the edge of the shoe-sole, from which line the necessary or desirable variation is made while pegging, by moving the wheel forward by the lever e2.

All these details of improvements tend to make these machines more eicient in their operation, and enable the work to he performed with more'ease to the operator, and with greater expedition.

I claim the arrangement of the peg-cutting mechanism, so that but one peg is cut at the `end of the pegwood, which peg, after being cut, is fed forward under the driver, substantially as described.

I also claim the combination ofthe ratchet-driving pawl m with a reciprocating slide, n, to which the pawl is jointed, and by means ofwhich it is actuated, substantially as described.

I also'claim, in combination with thepcg-feed wheel rl, feed-ratchet l and ratchet-driving pawl m, the ratchet-detaining pawl s', substantially as shown and described.

I also claim, in combination with the peg-.wood-feed wheel cl, the spring 7L, pressure of which is adjusted by the screw 7i, substantially as set forth.

I also claim, in combination with the slide b2, spring d?, and lever e3, the adjusting-plate h2, substantially as and for the purpose set forth. i

I also claim, in combination with the ratchet-driving pawl m and the reciprocating slide 1t, to which the pawl is jointed, the cam p, for driving the slide'n, through the lever r and connecting-rod s, substantially as shown and described.
