MASSACHUSETTS. 1

MACHINE FOR CRIMPING LEATHER.

Specification of Letters Patent No.

To all 'whom it may concern Be it known that we, GEORGE ALGAR, of Grcenport, in the county of Columbia and State of New York, and MAJOR ALGAR, of Hartsville, in the county of Berkshire and State of Massachusetts, have invented a new and useful Improved Instrument for Crimping Leather; and we do hereby declare that the following is a full, and eX-` act description thereof, reference being had to the drawings accompanying and making part of this specification. A

Our improvement consists in an instrument such as will be hereafter described to be attached to the leather while on the crimp to give it a perfect finish without breaking or injuring it as is the case with those machines which perform the operations instanter.

Figure 1 is a perspective view.. Fig. 2 a section showing the interior, a, a. Figs. 1 and 2 represent a circular metallic plate of the required size of the instrument the two extremities of which form in part the front` end of it with such a space between them as is necessary for admitting the thickness of the back of the boot form, and constitute inner jaws the outer of which will be now described.

Z; Figs. 1 and 2 represents them passing through an aperture o Figs. 1 and 2 in the circular plate, and turning on a .suitable fulcrum el Fig. 2, their inner ends and sides extending to and resting againstV a screw which will be hereafter described. Grooves represented by the dotted lines, e, Fig. 2 are made in these sides in which the screw 1,016, dated November 25, 1838.

revolves, or turns. These cross jaws so formed are acted upon and closed by `a wedge f Figs. 1 and 2 with a female screw cut longitudinally through its center. The screw g Figs. 1 and 2 then passes 'through an aperture in the center of the circular plate and works into the female screw in` the wedge so that by screwing out, (the outer end of the screw, which is surrounded by a circular plate h, Figs. 1 and 2 resting firmly against the back of the boot form) the wedge is made to act upon the cross jaws gradually closing them, and while in the act of crimping the degree of the power of compression in the jaws, is made to correspond with the resistance against them.

, Fig. 2, represents springs attached to the inside of the circular plate `which pass against the outside of the inner part of the outer jaws for the purpose of opening them scribed.
