T0l all whom t may, concern Be it known that I, CoLLiNs H. JAQUITH, of Keene, in the county et" Cheshire and State of New' Hampshire, have invented a new and Improved Machine for Crimping Boots, of which Il declare the ollowi'ngto -be a full and exactl description.

The principal parts of' this machinethat are made of wood are two frames called'the outside frame andthe sliding frame. :The outside frame stands on two feet', being timbers three inches square, andaboutj two anda half feet long, .connectedby two cross timbers or tiesV frame into the other tinibers near the ends, the foot'v timbers being one foot ten inches apart from inside toV inside.

feet high, two inches thick` and eleven inches wide at the bottom; which'width continues upward but six inches and-is then narrowed' an inch oneachside. These posts are two feet apart from-inside to inside.A Oiiefoot above the foot timbers, two Vgirts, three by' two inches are framed intothe posts, the i irt being flush or evenp with the front sidesof" the posts. Andthe interva lbetween the girts being three and a half' front inches; Seventeen and a half' inches above these girts, another of the saine width as the posts at thatv place, and about three inchesthick is framed'into the posts by-v two tenons at each-end, the frame beingmad'ei strongv andl rni'byv thejoint? screws at all the principal joints; Through themiddle of'this girt at each end `close to the posts are holes for the side pieces of the sliding..

frame hereafter mentioned to move in. This sliding frame moves upV and downfwithin the other.

size. These two cross timbers are connectl ed by an upright post, two and a halfl'by two inches, on the righthand'side o fwhich is acastiron rack, andwhich side lis twelvev Into the middle of these timbers, two upright post's,y which may be'inade of plank, are trained about three and? a half' The side piecesv are foi-1r feet' eight inches long'or hi h, two inches widev and one and ahalf` thick. They are con-- nected at the bottom by a cross timber, two by three inches, and one/foot four inchesabove, by another cross timber of the same on a side adaptedy and use d toftake hold of g the corners andsides of the leather and sti'etChjit', are attachedto, er connected with, this plank in this way. ATwo square grooves about' aninch wide and three fourthspof anl finch deep are cutl on each side,opposite each gother,` starting.l from the angle and vrunning to the top. rI h'ese grooves-are covered with thin plates of'. iron fastenedon-the .out- 'sideof the plank`v with screws.` At about half` anl inch from thel top an; iron. arbor nearly aninch in `diameter passesthrough ythese plates andthrough the :wood-between `ithergrooves Aat rthe center of" the gi"ooves. In front thisaijbor has uponita bur Wheel 'two and a half inches inA diameter andaf zsmall crank, and? at the left' haiidis fined'v .a dogfor the bur wheel;4 The. pincersfpass up and down these grooves. They arejm'ade O' two-pieces ofy iron kept a'short distanceapart'by a piece of meta-llbetweenthem near .the upper end; there-isa rivet through the upper end of thev pieces of iron, andv ag' thumb screw at'thelower end. One end of astrip of leather is fastened. around the rivets and.-V the other to `the arbor by passing through a inortisefinwit By turning the crank the' strips of leather are wound around'the arbor and the pincers are-raised,

and'by turning the crank the other way they are let' down. About three andahalfinches j from thesegrooves attheA lefthand `aretwo more, with pincers &c., ysimilar to the others in all respects exceptthat'the grooves de-r` cline froinajperpendicular toward the lei:`t

and are wider at the lower thanxat theupper end.' Into a gi'oov'e half an inch deep vmadeliiito the-,under sidef of' the aforesaid plankis inserteda plate made ofmetahbut Zinc isf preferable, calleda forii'nthree sixteenthsof an inch thick, and'of ther shape represented in the drawing the ends of the ferm being .also insertedinto the side l. timbers of' the slidingirame andthe lower edge beingnished round.' The widthofA the form varies'. Gn the left` itis from-four. and'a halfto six inches5at the top about Zeight inches,.on the right form'livefandfa Y half' to sinV and a half! inches. The slidingv iframe justiills fthe intervalbetween theuprightposts above mentioned, is placed between the lowerggirts andclose to the b ack Vvone,andtheside pieees move-in the afore-` saidy holes through the upper girt, and.v .square gains are cut' in the Vfeet to permitl the side pieces to descend tothe floor. Tovkeep it steady cleats may 'be'nailedto the upright posts. To the outside of the left side piece of the sliding frame is attached an iron plate an eighth of an` inch thick (the'wood being cut away-t0 that depth) instead of these small plates, a single iron plate of the same size as the other, Vmay be bedded into the post. l

The jaws shown in the drawings (I) are of cast iron. Their width at the bottom is about twelve and a half inches; their height from the bottom tothe point is about one foot six inches; the length of the left hand slope (the jaws being `placed together)is about seventeen and a half inches, and of the right hand slope about ten inches. A perpendicular line being dropped from the point one foot, the distance thence horizontally vto the left edge is'about nine inches. The slope on the other` side is not quite so steep. should be smooth are an inch and an eighth thick and diminish gradually in thickness tothe bottom of the slopes, the thickness at the bottom of the longest slope being half an inch. The jaws may be cast with a rim along the slopes on the outside from an inch to halfv an inch wide, widest at top, and with a perpendicular strip three inches wide and an inch and aV half thick extending from the pointv downward to the Y ledge hereafter mentioned, and the remainder three eighths and an inchandia half thick extending from the bottom a ledge projecting outward three fourths of an inch and square at the bottom crosses 4the jaws horizontally. Two grooves or mortises are sunk into the, top of the upper` girt, in Ywhich the bottoms of the jaws are inserted up to the ledge. These grooves .are a littlewider than the jaws are thick, and are separated by a partitionhalf an inch thick, which must be exactly under the edge of the form. The inside of the jaws j are polished as far down as the leatherV comes in contact with them, and to facilitate the polishing so much of them is a little raised when cast. The two `jaws must be cast in dierent molds. As the smooth sides are placed together, one jaw is Vthe reverse or counterpart of the other. j

. Through the thick perpendicular strip in the jaws about eight and a quarter inches below the point passes a bolt Von the back Y end of which is a head and on the front end is a hand nut, the use of which is to open and shut the jaws, and to set them at any desired distance from each other. 4Through the thick part of the back or front jaw, near the bottom passes a thumbscrew, bywhich At the point the edges which the` distance apart of the bottomof the jaws may be regulated.

The angle Aformed by the lower edge of `the form, and the upperedge of the jaws,

should not be thesame.` When the form is brought down, so that its edge but just enters between the points of the jaws, the lower end of thel form on the left is .about hand'a'tra'nsierse` groove is made in both lower girts, to receive the arborY or axle of a cast ironwheel shown in the .drawing (Q). Small blocks of wood are fastened by screws overl this axle to keep it in place. This wheel is twenty inches in diameter and` is placed. betweenthe two (girts, and in front `Back of this. .wheel connected with itand turning o n the of the sliding frame same axle is a pinion the cogs of which .mesh with those cfa cast iron rack (P) attached to the` upright post in the sliding frame. .b

To the underside of the nupper girt (B) is firmly fastened by screws, a wooden block (M) seven inches long, and three and afhalf wide, by three anda half thick. Through the middle of this, about seven inches from the inside of the. right hand post, a `square `bolt passes, from each. end of which hangs an iro-n plate about sixinches long, an inch.

and a half wide, and half an inch thickl Through the lower ends of these plates passes an axle or arbor upon which is fastened a cast iron pinion about three inches `in dialneter, the cogs of which mesh with Athose of the large wheel below.. On the front end of the axle is placed an eleven inch crank, by turning .which the sliding frame is raised or lowered according to the way it is turned. The sliding frame being raised, the jaws being set at a proper distance from each other by means of the thumb screw and hand nut, and the leather being properly placedl on the jaws the form, by turning the cra-nk is brought down, press ing the leather between the jaws, as far as Vmay be necessary to` complete the crimping.

' I claim `as my invention- The use of the thumb screw, at the bottom to regulate the jaws for the introduction of thick or thin leather and the mode of using 'the pincers by means of the strap running,

over the arbor all as above described.
