muovi-:D BooT-cRIMPER To all whom 'it may concern Be it known that I, WILLIAMB. GLEAsoN, of the borough of Conneautville, in the county of Crawford,

and State of Pennsylvania, have' invented'a new and useful Machine for Crimping Boots; and I do hereby l declare the following to be a full and exact description ofthe cousin-action and operation of the same, refer'- ence bemg had to the accompanying drawings, and the letters of reference marked thereon, the same being a vpart of this specification, in whichlows:

A wooden or iron frame-work, consisting of two uprights, F F, and a cross-piece, J, is first constructed.

On the inside of the uprights is cut a groove, T T, with the guides G G G G.

In these grooves iit the cogged rack-slides G and D, which are propelled by the gears B B on the shaft A, with the lever E.

These are hung on the uprights, F F, by the brackets H H.

This portion of my invention, together with the crimping-board L, I denominate the brake.

- Tenoned into the cross-piece J, are the two jaws, I I. These iit loosely in the mortises, so they can be spreadapart at the top.

Fig. 3 shows this part of my invention more perfectly, being a top view of the jaws, in which I I are the jaws, through which passes a bolt, K, on the end of which is a thumb-screw, U, which is used in giving more or less tension to the spring V.

By means of this contrivance the jaws are made adjustable, so that when the machine is being operated they will adjust themselves to the thickness of the leather.

The adj ustability can be varied by the thumb-screw U.

These jaws may be made of wood or metal, as may be desired.

Fig. 2 shows an inside view of one of the uprights, F, together with that portion of the brake which is thereto attached, i. e., the half gear B, the rack D, and the guides G G. j

Fig. 7 is a top view of this portion of my invention.

On the lower end of the rack D, in fig. 2, will beseen a mortise, Y, and a similar mortise will alsobenoticed at the upper end of the rack C, in iig. l. y

In these mortises fit the ends of the crimping-board L, seen in iig. l, which, as has been before mentioned,

forms a part of the brake.

Figs. 4, 5, and 6 are sectional views of this portion of my invention.

VThe crimping-board L is made of any absorbingmaterial of suicient strength.

Projecting from the crimping-board L are the arms Z, Z2, Z3, Z, and Z5, (the latter, Z, is not seen, but its place is indicated by the position of the letter in iig. 1,) which act as guides to the grab-bars S S and M.

These bars are triangular in shape, as will be seen in the sectional views, figs. 4, 5, and 6, and they are also ribbed o r notched.

Fitting over these are the spring-grabs O O O O and Q, which are v-shaped, and are notched or ribbed so as to correspond with the grab-bars, thereby being4 capable of griping the leather firmly.

a. a. a a a are strips of leather, which are designedy to show the action of the grabs.

Passing through the grab-bars yS S, at the points marked X X, are thumb-screws P l?, which have their bearings on the crimping-board L.

By means of these screws the grab-bars S S can b'e raised, and the leather be stretched, to suit the oper-' ator.

The grabs marked() can be increased in number, to suit the operator.

The grab Q and grab-bar or block M are held between the arms Z2 and Z3 by the bevel-guides on the arms and grooves in the ends of the grab-blockv M.

This grab is operated by a crank-screw, It, whichis fastened to the grab-block M.

This screw has its bearing on the top of the crosspiece b, which is fastened to the top of the arms Z2 and Z3 by a mort-'isc and tenon. A

This grab is used in stretching that part of the boot known as the shank, and, as the wrinkles caused by braking and crimping come in this part of the boot-top or upper, more care is needed than at any other point; and on account of the thinness of the grab-block M,

the leather is drawn closeto the crimping-board L,

. of. my invention, it will be seen that the crimpingboard L is wedge-shaped. This, in connection with the adjustable jaws I I, insures, I claim, a more perfeet brake than has heretofore been in use.

The manner in which my machine is operated is as follows: l

The boot-upper or front which the operator desires to crimp is rst moistened, as usual, and is then placed in position on the face of the jaws.

`The lever E is then brought down, and thus, by means `of the cogged gears B B and the rack-slides G and D,

the crimping-board L is vforced down between the jaws,- drawing the boot-iront with it. This brakes the boot. The grab Qis then attached to the corners of the Y shank, and is then screwed up as tight as may be deemed necessary.

The lever is then raised, and the thumb-screw U may be tightened a little: then the lever is again forced down.

The grabs O O O O are then attached, and the thumbscrews P P are applied. This draws the foot and leg of the boot-front to position.

The lever may be then worked up and down a few times, and all the grabs tightened.4

' The boot is then crimped, when the crimping-board L audits immediate attachments are removed, and th leather allowed to diy on -the board.

A new crimping-board is attached to the racks C and D, and the work goes on the same as described. l

Herein will be noticed one of the objects of my invention, viz, obviating the necessity of first braking the boot-ont, and then removing it from the brake, and drawing and tacking it on to the crimping-board by hand, as has heretofore been done.

Each machine is supplied with as many crimpingboards (thereby meaning the board L, bals S S, block M, and grabs O O O 0 and Q) as the purchaser may Witnesses:
