TO ALL JVHOM IT MAY CONCERN: v v I Be it known that I FRANK O. OLAFLIN, of Brooklyn, in the countyo f Kings, and State of New York;

have invented, made, and applied to use, a certainnew. and nseful Implement for Lasting Boots and Shoes,

and stretchingand tacking other articles; and I do hereby declare the following: to be a full, clear, and exact description of the said invention,reference being bad to the annexed drawing, making part of this specifica- -t ion, wherein- Figure 1 is a side view, showing the jaws of the stretching-pincers, and part of the conduetor for' the tacks. Figure 2 is a vertical section, of-the tack-driving mechanism, at the line we, Figure 3 is a plan of the tack-holder, and j Figure 4 is a section of the plunger and separator, detaehed. 5

Figure 5 isa side View of this apparatus in a form adapted to drivingwooden orother pegs": Figure dis a sectional view, the two parts of the stock being separated, to show heawlsand punches- Figure is aseetiqn of the knife that cuts off the pegs from the strip of wood or other material. I Figure 8 is a side view of the rod, awls, and punches; and l p i Figure 9 is a view of the rear side of the plate, carrying the pawl that operates the feeding-roller. Similar marks of reference denote the same parts. 7

In'lasting boots and shoes, it has heretofore been usual to introduce the last into the upper, then lay upon "the sam'e'the insole, and stretch the uppers around the last, drawing'the edge of. the leather over the. insole,

and Securing the same in that position by means of tacks or pegs; then the outer sole is applied, and the whole secured together by pegs or nails, or by machine-sewing. In this manner of lasting there is diificulty in keeping the leather under proper tension, because the workman-first draws the leather with-his pincers, then holds 'a tack or pegivith'theother hand, and releases the hold of'the leatheiyin ordertomake use of the'hammel head of-the pincers in driving the nail.

' The same remarks apply generally to stretching and tack ingthe c'overing or. upholsterygof difieren't articles.. The hold on the same-is often necessarily released before the tack is'inserted, becausethe tack has to be inserted and driven by an instrument, or operation separate from that employed in'stretching.

The ob'ect of-m invention is to combine inone' mechanism the two 0 erations of stretching and tackin J Y P p or pegging, so that the leather or other material can be properlystretched and held until secure.

My said invention is primarily intended for lasting boots and shoes, butmay be'applied to stretching il 4 tacking other articles. v

And my said invention consists in the combination of pineers for stretching, with mechanism for driving the tacks or pegs for securing. Y v

In the accompanying drawings I have represented my said invention as applied to lasting boots or shoes, and from the said drawings and descriptionany skilful machinist will be able to'vary the form and proportions -to suit other purposes. v r v a r In the drawing, a represents a pair of pineers, such as required when the same are to be employed for lasting boots and shoes. The projection b may be provided to act as a fulcrum or point of resistance in stretching the leather. r g Upon the upper jaw of the -pincers,'the tack-driving mechanism is applied, and the same may be made permanen with thejaw, as in fig. 1, or removable therefrom by a dove-tail groove and tapering block, as seen in fig. 5, or otherwise.

The driver consists of a slide-rod, c, with a head, a, to be struck by the hand or otherwise, a spr g,

to return the driver to the normal position, and the mechanismv within the stock 01, for presenting the tack,

peg, rivet, or other varticle to be driven, to the action of' the punch or driver, that receives its motion from .said rod 0. 1

The tack-driving mechanism, figs. 1,2, 3, and 4, consists of a punch, e, extending from the rod 0, and the devices for presenting and holding the tacks.

ff are jaws, hinged at their upper sides, 2, and kept towards each other by the springs 3 3, and in the surfaces of these jaws are tapering grooves, forming, when together, a tapering hole, as seen in fig. 2, for receiving and guiding the tack 4. I

g is a conductor, slotted, for the tacks to hang in by their heads, and slide down towards the jaws ff, and at the upper end of this conductor is the receptacle h, for tacks, and the inclined recess 5.

The tacks may be shaken out of the receptacle h,'through the opening 6, and falling into the recess 5, will pass into the conductor g, and from that be talen, one at a time, to the jawsf. A cover may be provided for the receptacle it and recess 5.

The faces of the jawsf are bevelled, as at 16, and a separator, z', is placed between them and the conductor g.

The lever 2", of the separator i, is mounted on a fulcrum, 7, and the head of the lever is operated by the rod c. i i

The rod c is grooved, as at S, to withdraw the separator, as the punch or driver descends to drive in a tack, and the inclination of the lower end of the groove 8 acts on the head of the lever i to force the separator between the conductor and the jaws.

The punch e, in driving the tack out of .the tapering hole between the jaws, opens those jaws, and as the punch and its rod, 0, rise, the separator i forces the lowest tack in the conductor, that had hung between the inclined faces, into the tapering hole in said jaws, ready for the next movement of the driver, so that the operative, after having stretched the leather or other material by the pincers a, secures the same instantly by a tack, .which is driven by a blow upon the head 0' of the rod 0.

Themeehanism, as above described, is designed for ordinary metal tacks, but if it should be desired to use wire, either twisted or plain, to form a rivet, this may be effected, either by supplying the wires one at a time, or by substituting a cutter, operated in place of the separator i, to cut off one piece of wire each time from a coil or length.

The mechanism for driving pegs corresponds to that before described, only that I-provide a means for perforating the material by an awl, and then introducing the peg.

The perforation is done with one blow on the rod 0, and the peg is fed upon the upward movement, and driven by a second blow upon the head a of the rod 0.

Two awls, It, are mounted-on opposite sides of a revolving head, I, that carries the two punches e'c at right angles to the awls k. This head Z is square, and has a steady-spring, 9, on one side, and it is turned a quarter revolution every time the rod 0 rises to change from an awl to a punch,.by the notches at the angles of the head striking against the end of the spring 10. Any other equivalent means may be substituted.

A roller, 11, is used to feed in the strip of wood or other material from which the pegs are to be out; this is operated by a ratchet-wheel, 0, and pawl 12, (see detached fig. 9,) and this pawl 12 is moved, at every other reciprocation of the rod 0, by a pin, Z that projects on two sides of the square, Z, of the revolving head Z.

The material to form the peg is cut by a knife, 13, that is drawn back, out of the way, by a spring, 14, but as the head I is pressed down, the slide 18 is moved by the pin 15, on the head Z, and acts upon the inclined back of the knife to press it against the wood or other material, and separate the peg, which is then moved to the position for being driven, the movement of the material by the feed-roller a effecting this object.

It will be evident that any clamping-mechanism that will hold the material while being stretched, may take the place of the pinccrs that are herein represented.

That I claim, and desire to secure by Letters Patent, is-

The combinationof the mechanism for stretching and holding the material to be secured, or the equivalent thereof, with driving-mechanism, substantially as and for the purposes described.

In witness whereof, I have hereunto set my signature, this 16th day of July, 1868.

F. O. GLAFLIN.
