ELEAZER KEMPSHALL, OF NEWV BRITAIN, ASSIGNOR TO THE KEMPSHALL PATENT BUTTON FASTENER COMPANY, OF DERBY, CONNECTICUT.

BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 310,524, dated January 6, 1885.

Application filed April 14, 1884.

To all whom, it may concern:

Be it known that l', ELEAZER KEMPsHALL, of New Britain, in the county of Hartford and State of Connecticut, have invented a new and 5 useful Improvement in Button-Fasteners, of which the following description and claim constitute the specification, and which is illustrated by the accompanying sheet of drawings. Figure 1 is a section of a piece of leather or IO cloth with a button attached thereto by means of the present fastener. Fig. 2 is a View of the flat blank of sheet metal from which the button-fastener is formed. Fig. 3 is a view of the left-hand side of the button-fastener com- 1 5 pleted, the front view of the same being shown in Fig. 4.

A is the leather or cloth to which the button is fastened. P) is the button. 0 is the button-fastener. The button-fastener is com- 20 posed of the base D and the hook E. That hook is formed by bending the shank F of the blank into the form shown in Figs. 3 and 4. The end of the hook is substantially even with the bottom edge of the base.

25 The mode of attachment is as follows: A

hole of suitable size is punctured through the leather or cloth. The eye of the button is then forced through that hole from the upper side, and then the fastener is hooked into that eye 0 on the under side of the leather or cloth.

(No model.)

Then the button is pulled outwardly till the fastener occupies the position shown in Fig. 1. The mode of operation is as follows: WVhen strain is exerted upon the button,the pull upon the fastener is somewhat diagonal, because the 3 base offers more resistance than the end of the hook. The result is that the end of the hook is drawn upward, so as to be about flush with the under surface of the leather; but it is not drawn upward far enough to pull it out of the hole entirely. Were the hook much shorter than it is, it would be thus pulled out in use, and were it much longer than it is, it would protrude from the undersurface of the leather, and thus be apt to irritate the wearer. 4

I claim as my invention A sheet-metal button-fastener consisting of the base D and the hook E,integral therewith, the said hook projecting from one out edge of said base, and having one substantially semicircular bend, and a straight end below said bend substantially parallel with the post of the hook, and its extremity substantially even with the lower cut edge of the base, all substantially as described, and for the purpose 5 explained.
