MACHINE FOR GRIMPING LEATHER FOR BOOTS,` &o.

Specification of Letters Patent No. 656, dated March 26, 1838; Antedated September 26, 1837. i

To all whom it may concern:

Be it known that I, JOSEPH ADAMs, of Fairhaven, in the4 county of Rutland and State of Vermont, have invented a new and useful Machine for Crimp-ing Boot-Fronts; and I do hereby declare the following is a full and exact description.

The nature of my invention consists in the construction and combinationV of jaws and carriage for a boot crimp to rest on with a double vise castiron wheel and pinions and cranks, and rack so attached as to work the whole of the machine so as to produce the intended effect, of crimping boot fronts.

To enable others to make and use my invention I will p-roceed to describe its construction and operation.

I construct the frame of my machine in the following manner: Two posts four feet seven inches long and two inches and a half square (as shown by letter B in the drawing) and worked into two'sills, eighteen inches long of the same dimensions of the posts (shown by letter K) and connected by a girth twenty one Ainches long of the same dimension, about three inches from the top of the posts and (shown by letter A) and by another girth of the same dimenf sions (also shown by letter A) about eighteen inches from the bottom of said posts, two wooden jaws ten inches wide and twelve long (as shown by letter C) and framed into the upper girth near the center and pointed at the lower end to fit the crimp, the point of said jaws to hang directly over the angle or curve of the crimp hereafter mentioned. VThese jaws are supported by two braces of convenient size.` To prevent them from splitting an iron bolt about three quarters of an inch is passed through the jaws and braces about seven inches from the points of said jaws with a square flat head on the back side and sunk in to the brace to keep it from turning and a screw on the other end, with a crank about six inches long,'and nut on the end, to shut the jaws, which are set in the girth so as to make them slightly movable, so as they may open and shut, a straight spring of sufficient strength is inserted between the jaws Vso as not to infringe with the bolt and action of the machine, for the purpose of opening them, with cresases in the inside of the jaws, to force the leather on to the crimp, a carriage constructed of bed work (as shown by the letters M and N) and ,framed into a ced piece of the' same size of the posts l is made of vplank of the same thickness of the bed piece and tted to the crimp with genes 1s, thebed work at each end ofthe crimp and center, to receive the said crimp and keep it in its place. Two pairs of reversed jaws indentedint-o the heelwworkjat right angles from the crimp (as shown bythe letters E) oflsimilarshape of the others with hooking crimps on` the instep ,to eri--` tend the leather and shui; in the same manner of the upper jaws, as shown by the `letters F on the-head of the bolts, and `small spiral springs inserted between the jaws just below the bolt Vto throw them open, with a small girth of wood at` the bottom of the jaws working at each end like a hinge to keep the lower end of the jaws from spreading so as to extend the top or mouth of the jaws to receive the crimp and leather, i i

with a piece cut out of the bedwork for the `girth and bolt to work in, a cast ironrack is attached to the bed piece (as shown by letter Q) about an inch and a quarter Wide of sufficient thickness, with half inch cogs,

Vand passes4 down through the lower girth.

This rack is moved by a pinion wheel (as shown by letter P) of 3 inches and a half spangler sunk into the lower girth so as to connect with the rails, a shaft passes through the pinion and a wheel of about fifteen inches diameter (as shown by O) and one end of the Shaft resting on the girth and the other on a standard (as shown by letter I) and mortised into a cross piece resting on the sills as shown by letter J and turned by a crank twelve or fourteen inches long attached to the shaft that passes through a pinion two inches and a half di-V open. lAn iron slide six inches long, halt .aneinch wide, anda quarter vthick passes through a bolt Yand staple that fastens it to the lower girth as shown by'letter L) and slides into a notch in the right of the shank of the Yvise about one inch from the bot-tom of the'shank to hold it fast. Two pairs of Vclamps (shown by U) attached to the upper sections of the bedwork and shut in the same manner as ythe jaws to fasten the top and toe of the boot front to prevent its sinking at'the instep and ankle in thin tight leather a small slide and spring` attached to the lower side of the bed piece, A(or spring) to snap into the notches on the right side of the vise to hold it when the Vcorners of the boot is brought to their proper place.

f All of the machine must be made of some good durable hard wood, except the castings, and all of the jaws may be faced with sheet brass or copper to make them more durable but is not necessary except for durability.

T0 make an operation with the above described machine, the leather must be thoroughly wet and doubled in the center and placed in the crimp. Then close the upper jaws with the crank attached for that purpose to a suitable distance to Areceive the leather and crimp. Then move the carriage up with the crank attached to the pinion T so as to force the leather and crimp between the upper jaws. Then open the jaws and let the carriage fall down and fasten the vise with the slide, attached for that purpose. Then lower the carriage so as to project the rim ahovethe bedwork on each side of the crimp. Then place the corners Vclose them with cranks on the end of the bolts marked f, and close the upper jaws as before, and force the leather and crimp up inbetween the upper jaws, which will force the reverse jaws back to their place and the leather is ready to tackV 0n to the crimp and take out of the machine.V In case of hard stubborn leather the corners of the boot front had better be brought down bv degrees7 by drawing the corners of the/boot front one or two lnotches'atv a time. Then let the viseloose and drive the leather and crimp up into the upper jaws to prevent wrinkles risingin the curve of the crimp,A

so continue the operation until the corners are brought to their proper plane. Then proceed with the reversed jaws as above.

I claim "as my invention, and desire to Y secure by Letters Patent- The reversed jaws E, E, constituted and operating substantially as` herein described and I claim them also, in vtheir combination with the jaws C, C, as herein described.
