IMPROVED BooT-cmurme mounts.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, R. H. DORN, of Port Henry, in the county of Essex, and State of New York, have invented a ne w and improved Boot-Crimping Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in'the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The nature of my invention relates to improvements in apparatus for crimping boot-stock, whereby the same may be performed in an expeditious and uniform manner, and it consists in the arrangement, upon a suitable bench, of a slide made to move back and forth by opinion gearing into a rack on the under side of the same, on which rack a series of ri-ght=angled formers is carried on its upper side.

These formers are caused to pass between two clamping or pressing-jaws, which are moved in an opposite direction by gearing in a similar manner, and are provided withsinoothing-rollers which bear against that part of the leather which is cri-mped in the angle of the formers, and turn in a direction so that the surfaces of the said rollers that come in contact with the leather movc opposite to that in which the leather is being carried by the formers, so as to produce a smoothing or rubbing action.

The said clamping-jaws are provided, ,on the inner sidesof the samc,with iron plates having right-angular grooves or ridgcs'formed within them, and arranged, with reference to the formers, in a direction opposite to the inclination. of the formers, so that their action on the leather will be to smooth it from the angle outward in' either direction, as willbe more fully described on reference to the accompanying drawings, wherein- Figure 1 represents a side elevation of 'my improved apparatus.

Figure 2 is a cross-section of the same on the line a: :i: of fig. 1; and,

Figure 3 represents an inside view of one of. the singularly-grooved plates aflixed to the'clamping-jaws.

Similar letters of referencc indicate corresponding parts.

it represents a bench, on which the slide B is caused to move back and forth by means of the pinions a,

shaft (1.

b 5 represent right-angled crimping-formers fixed in a vertical position'on the top of said slide B. y

c 0 represent two clamping-plates, which are also caused to slide back and forth on the table by means of the pinions b b on the crank-shaft'C, but in an opposite direction to that in which the slide B moves, one on each side of the former-slide B.

The said plates care provided on their inner sides with iron plates, D, having right-angled grooves and ridges, but which are set, with reference to the formersb", in a direction opposite to the same.

E E represent vertical rollers fixed in openings in the side-plates 0,150 which rotary motion iS-COmlIIHDiOS-tGli by means of pinions on the lower ends of the axles of the some, which gear into stationary racks d d, arranged on the top of the bench, as'the plates cc slide back and forth. The said plates are prevented from separating at the top by the tie-pieces cc. i v I Thc'operation is as follows: The leather to be erimped is placed on the formers, in the proper position, and held in place temporarily-by tacks, or it may be placed on. by an attendant as each former is about to pass between the plates.- Motion beingapplicd to the driving-shaft in the proper direction, the slide B and formers b will be passed between the olamping-plates c, by-which the parts ofthe leather lapping around the sides of the formers will be pressed and smoothed hard against them by the ridges onv the inner iron platesD, which, being arranged so that their angles of inclination are opposed to those of the crimping-formers, will press the leather from the points or 'apexes of the angles of the formers in each direction upward and downward from the said points, thereby producing the best effects on the leather to smooth and set the same. As the farmers continhe in their passage through the saidclamping-plates c, the leather is brought into'contact with the rollers. E E on each side, which are intended to act more directly upon that part of the leatherwhich is bent around the angles of the formers. i w

reuse 2 The surfaces of these rollers which act on the leather are caused to move in the direction opposite to that in which the slide-B moves, thereby giving a greater amount of smoothing effect to the same.

Having thus fully described my invention, what I china, and desire to secure by Letters Patent, is--- The slideB, provided with thecrimpingiormers b, in combination with the clamping sliding jaws c c, substantially as and for thepurpose described;

The slide B, provided with the crimping-forms b, in combination with the clamping sliding jaws a c, prorided with the ridged plates D, substantially as and for the purpose described.

The combination, with the plates c c, slide B, and .crimping-forms, of the smoothing-rollers, substantially as and for the purpose described.

The above specification of my invention signed by me,-this 14th day of February, 1868.
