T all whom t may concern: movable thereon for the purpose of length- Be it known that I, SILAs HART, of New ening and shortening the screw.
Haven, in the county of Oswego and State L is a screw for holding the tube at any of New York, have invented a new and usedesired position on the shaft. 55 ful Improvement in Machines for Lasting The slide is a piece of metal containing Boots and Shoes, which is described as fola round opening in the center thereof correlows, reference being had to the annexed sponding with the cylindrical portion of the drawings of the same, making part of this male screw made to turn therein. It also Y speciication. contains two openings to admit the arms 60 Figure l is a plan of the machine. Fig. 2 which are `inserted therein, each opening is a plan of the slide detached from the containing an antitriction roller. The slide arms and screw.

Fig. 4, section of the screw-shaft by collars and pins and remains extension tube. stationary during the operat-ionof drawing 65 The nature of this invention and improvethe arms through the openings therein.
ment consists in Contracting and expanding Operation: Turn the screw to the left the arms containing thejaws for gripping the until the nut to which the arms are jointed edges of the upper of the boot or shoe, by is near the slide, which at the same time ex means of a slide that embraces or encircles pand the arms; then bring the leather over 70 the arms, said arms being` moved toward or the last and insert the edges in the jaws and 'from the last simultaneously with the opsecure them by the screws ot the jaws. Turn eration of turning the male screw in a the screw to the right. This operation will female screw in the center of the nutl to cause the nutrand arms to recede from the which they are connected by which the angle last and bring the arms against the rollers 75 of the arms with the screw is diminished in the slide causing the arms to close toward in lasting the upper and increased in .unthe screw; at the same time drawing the lasting it by reversing the operation of the leather around the last, the power increasing screw, thus removing the objections existing as the angle decreases of the arms with the in the use Aof the machine where the arms screw until they are nearly parallel with 80 are expanded and contracted by a separate the screw.
