SPRING CATCH OR FASTENING.

SPECIFICATION forming part of Letters Patent No. 326,331, dated September 15, 1885 Application filed June 6, 1885. (No model.) Patented in Canada June 16, 1885, No. 21,9ll.

To aZZ whom it may concern:

Be it known that we, JOHN DANFoRD' RIP- soN, mechanic, and ROBERT WATSON, manufacturer, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have jointly invented an Improved Spring Catch or Fastening, of which the following is a specification.

The object of the invention is to devise a simply constructed, cheap, and effective spring-catch, more especially adapted for coffins and caskets; and it consists in the peculiar combinations andthe construction and arrangement of parts hereinafter more fully described and claimed.

Figure 1 is a perspective detail, partiallyin section, of our improved spring-catch. Fig. 2 isa perspective detail of the button designed to fit between the lips of the spring-plate. Fig. 3 is a perspective detail of an equivalent for the button. Fig. 4 is a detail of the springplate before it is riveted to the stationary plate. Fig. 5 is a detail of the stationary plate. Fig. 6 is a detail of the pivoted separator. Fig. 7 is an illustration of our springfastener spread open.

Although our spring-fastener is specially designed for use in cofiins and caskets, it is quite evident that it will be serviceable in many other applications. We shall, therefore, direct attention specially to the construction of the fastener without special regard to its specific application.

A is a sheet-metal plate, made substantially in the form shown, so that it may be readily attached in position on the article to which the catch is to be applied. Of course the form of this plate will be altered to suit its specific application; but it should be flanged so as to form a support, a, for the pivoted separator B, its shank passing through holes in the plate A and support a, as indicated.

0 is a sheet-metal spring-plate having two projections, b, extending from its edges,which are designed to fit into holes in the plate A for the purpose of securing the spring 0, as indicated. Inwardly-projecting lips d are formed on the ends of the spring 0, which is bent U shaped, as indicated, and set in,so that the inclination of its spring shall be toward bringing its ends together.

D is a button attached to a plate designed to be fastened to the lid or other part to be connected to the article on which the plateA is fastened. This button D is shaped so that when brought into contact with the lips (I it will push the ends of the spring O apart, so as to permit the button to pass when the ac tion of the spring causes the lips to spring behind the said button and form the desired connection.

In order to release the button, the shank E of the separator B is turned so as to bring the wings of the separator against the sides of the spring 0, thereby pushing them apart and re- 6 5 lieving the button. WVe show the shank E with a crank end having a knob on it. It is intended that the shank should be sufficiently long to extend outside of the panel on which the fastener is attached.

It will of course be understood that instead of having a permanently-attached shank eX- tending outside of the panel, as indicated, the shank E proper need not extend entirely through the panel, and instead of a crank formed on its end in this case its end would simply be squared,so that the key may be easily fitted over it. In such an engagement it would merely be necessary to leave a hole for the instructions shown therein as forming part of 0 the separator 13, all arranged and operating plate A and support a, all arranged and opsubstantially as and for the purposes specierating substantially as herein shown and defied. scribed, and for the purpose specified.

The fastener described, consisting of the 1 Toronto, May 22, 1885. 5 plate A, flanged to form a support for the separator, the U-shaped spring-plate 0, having I projections b and secured to said plate thereby, and inwardly-projecting lips on its free In presence of ends, the button D, and the pivoted separa- CHARLES C.
