To all whom it may concern: In working with right lasts the bar will Be it known that I, EDGAR S. COMBs, a citinot be used on thejaw A, (shown in the drawzen of the United States, residing at Rochesings,) but will be applied to the jaw A on ter, in the county of Monroe and State of the opposite side of the machine; but when New York, have invented certain new and working with left lasts the bar will be rcuseful Improvementsin Lasting-Machines, of moved from the companion jaw A and apwhich the following is a specification. plied to the jaw A in the manner above stated.

My invention relates to the jaws employed In order to hold the bar or former C in in lasting-machines to'fold the edges of the place, one end is inserted into an opening E3 upper over upon the last or insole; and it formed in a plate 0, secured to the lower consists of a former, arranged to bear upon end of the jaw, while the opposite end is held the ends of the fingers or blades of the jaw to in place by means of a latch d, hinged or pivbring them into conformity with the curvaoted to the upper end of the jaw.
