HWUWTIW WITNESSES IN V'EJVTOR fV/AMW FRANK CHASE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE CHASE LASTING MACHINE COMPANY, OF SAME PLACE.
ILASTING=TACK STRIP.
SPECIFICATION forming part of Letters Patent No. 391,688, dated October 28, 1888.
Application filed July 27, 1888.
To all whom it may concern.-
Be it known that I, FRANK CHASE, of the city of Boston and State of Massachusetts, have invented a new and useful Improvement 5 in Lasting-Tack Strips, of which the following is a specification.
In Letters Patent No. 337,662, dated March 9, 1886, I have described and claimed a lasting-tack strip consisting of wire bent at intervals into loops pressed into tack form and pointed.
My. present invention is an improvement on the said patented invention; and it consists in twisting together the legs of the loop at or near the head of the tack.
The accompanying drawings illustrate the improvement.
Figure 1 represents the straight wire from which the tack-strip is made. Fig. 2 represents the wire after the loops have been formed. Fig. 3 represents the same after the legs of the loops have been twisted. Fig. 4 represents the same after the twisted loops have been pressed into tack form and pointed.
While showing the wire at these separate stages, it will be understood that the opera tions of looping and twisting the loops may take place practically simultaneously. My
present invention, however, is directed not to 30 the method of manufacture, but to the article itself.
In the practical use of my patented inven tion it has been found that the tack will pass for its whole length through the sole or insole.
5 The same insole will vary in thickness in different parts, and differentinsoles vary in thickness from one another. It is desirable to have Serial No. 281,163. (No model.)
tacks of such construction that while they are of the same length they will pass no farther through beyond a sole of one thickness than [one of another thicknessthat is to say, it is desirable that whenever the point of the tack meets the iron bottom of the last it shall there stop. My patented tack, however, will not do this at all times. The stem or shank advances without material change in shape until the head is driven home, while the point or inner end bends over and clinches and spreads upon the inner face of the insole. This of course is an undesirable thing.
My present invention is intended to and, in fact, does remedy the defect. The twisted formation of the part of the shank near the loop permits the tack to cripple or close up in the direction of its length at this point as soon as the point of the tack brings up against the sole of the last, and this crippling takes place throughout a greater or less portion of the length of the outer portion of the tack, according as that length may be in excess of the thickness of the insole.
What I claim herein as new andof my own invention is A lastingtack strip consisting of wire bent at intervals into loops, the legs of which are twisted together, )ressed into tack form, and pointed, substantially as hereinbefore set forth.
In testimony whereof I have hereunto set my hand this 19th day of July, 1888.
FRANK CHASE.
