l TO ALL WHGM IT MAY CONCERN:

Beit known that I, CHARLES M. GUsTIN, of Saccarappa, in thc county of Cumberland, and State of Maine, have invented a new and improvedY Jack for the Manufacture of Boots and Shoes; and I hereby declare the following to be a full,-clear, and exact descriptionthereof, which will enable others to construct and use my invention, making reference to the accompanying drawings` forming a part of this specification, in which- Figure 1 shows a side elevation of my invention.

Figure 2 is another view, illustrating the method of operation.

Same letters indicate like parts.

My invention has for its object the production of a convenient device for holding boots and shoes when being pegged, sewed, and finished. A shows a yoke resting on the chair B. C is a segment attached to thc chair, and sliding in aslot in the bed D. The chair swings on a pivot a set in' two blocks b on the bed D; the yoke A can be turned around on the chair B, being fastened thereto'by the bolt c l is a crank-stop, sliding through' holes in two blocks e, and fitting into holes in the segment C. The bed D is made to he screwed or secured to a bench, post, .or other support. TheI yoke A has the two upright arms .f and la; upon the arm fis the holder z'for the top of the 4toe of the boot or shoe; in the arm It isa slot for thereception of the spring c. This spring operates the arm l, swung on a pivot at m. By the spring the lower end of the arm is pushed outwardly, as illustrated inthe drawing. The upper end has a point to penetrate the hole in the top of theheel of a last; this is seen at n. The yoke A, by means of a friction washer o on the boltl c, `andthe nut, is bound or held somewhat tightly on the circular top, p, of the chair B, as it is desirable that the yoke should not move too easily on the chair. 'The swinging 'of the yokeenables the workman to turn the boot or shoe, and present either side thereof, as his convenience requires. When the soles of boots or shoes are sewed, the threads are passed through the ,sole ,from both sides, both top and bottom. By means of the segment and crank-stopthe shoe or boot can be placed at any convenient inclination for this purpose. The holder for the toe of the boot or shoe is adjustable, so as to slide backward or forward to suit different lengths, and is secured by ascrew. A shoe on the last is placed on the two arms of the yoke, the heelpn the point of the spring arm, the point penetratingthe hole in the top of the heel part of the last. The inclination outward, of the arm, by the pressure of the spring, confines and holds the shoe firmly on the yoke. The leg of a boot slips down over the arm z, of the yoke, thus avoiding folding the leg. v

I am aware of Letters Patent granted to Thomas D. Bailey, December 28th,'1858, and numbered 22,340, but the operation and'mechanical means in his invention are different from those in mine. do not claimmjack ing the last by turning the plate to which the lastis fastened, neither do I claim the combination of a lever, screw, and turn-table for Swinging the last, so as to p resent any side to the operator. I am' also aware of the Patent numbered 15,462, and dated July 29th, 1856, granted to"Alfred Swingle; but this invention is clearly distinct from mine, and I do not claim the devices therein described` The Patent numbered 15,406, anddated July 29th, 1856, issued to Alfred Swingle, is different from mine in the mannerin which the last is confined to the jack, and in the means used to present the -diiferent sides tothe workman. I do not claim thc spiral spring to hold the last, or the method there employed to swing the last sideways, or in verticalplan'e.' Patent No. 29,434, issued to Ephraim Harlow, July 31st, 1860, is for a spring to hold the heel lever; butIdisclaim a spring applied and operating in the manner therein shown, for such purpose. Letters Patent granted to Levi II. Proctor, May 22d, 1866, di'ers from my invention in several particulars, viz, in the ma'nner in which the heel and toerests are rendered adjustable to different sizes of lasts, the means by whichthe vertical movement of the lastholder is effected and regulated, and in being more complicated and expensive than mine. Also in the arrangement and construction ofthe heel spring in the heel rest'. I do not claim the several `combinations of devices, or any of them, as set forth in the claims of said patent..

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

1. The combination of the bolt c, and friction washer o, to prevent a too casyand ready revolution of the yoke A upon the bolt, in a horizontal plane. v

A2. The combination of the crank-stop ci, sliding in thc blocks e withA the holes in the segment C, as and for the purpose specified.

-' 3. The sliding toe-rest ou the top of the armf, when secured at any point in the manner descr1oed, and for f rtl. the PHPOsc Se 0 1 CHARLES M. GUs'rIN.
