FRANCIS HUPPERTZ, OF ST. FRANCIS, WISCONSIN.

SHUTTER-RELEASER FOR CAMERAS.

Application filed December 18, 1913.

To all whom it may concern Be it known that I, FRANCIS Horrnn'rz, a citizen of Germany, residing at St. Francis, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Shutter-Releasers for Cameras, of which the following is a description.

This invention relates to improvements in shutter releasers for cameras and more particularly to a device especially applicable to shutters of the class that gives instantaneous exposures.

The purpose of the device is to afford a means whereby the operator may obtain a picture of himself.

Another object is the taking of photographs at positions from which it would be dangerous for an operator to remain for a period of time.

lVith the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawing which forms a part of said specification and in which Figure 1 is a front elevation of a camera provided with my improved shutter releaser. Fig. 2 is a detail of a portion of the device. Fig. 3 is a plan of the fuse employed.

Like reference characters indicate cor responding parts throughout the several views.

In the drawing the reference numeral 1 indicates the camera which is provided with the customary shutter lever 2 which is formed with an aperture 3 in its end. In the apertured portion of the lever one end of a Wire link 4: is secured which link at its Specification of Letters Patent.

Serial No. 807,551.

opposite end is secured to a spiral spring 5 which is terminally secured in a suitable block 6 secured upon the base of the camera. Another wire link 7 also secured at one end in the apertured portion 3 of the shutter lever is terminally secured in the apertured portion of a slow burning fuse 8 which is formed with another link 9 which connects the fuse with a small flat spring 10 terminally embedded in a post or upright 11 also secured to the block 6; the post 11 is, moreover, provided with a support 12 for a bell or alarm 13 disposed adjacent one end of the spring 10.

After the camera has been set up and focused, the shutter is set and the lever thereof connected to my device as described. The operator now lights one end of the fuse, which is preferably made of a material that will smolder and burn slowly, and when the fuse is consumed the spring 5 is released from connection with the spring 10 when the latter will strike the bell 13 and the spring 5 will through the medium of the shutter lever operate the camera shutter.

hat is claimed is The combination with the shutter lever of a camera, of an actuating spring for said lever, a time fuse connected to said lever for normally retaining said spring inoperative and alarm mechanism normally supporting said time fuse and adapted to be operated by the destruction of said fuse.

In testimony that I claim the foregoing as my own I have hereto aflixed my signa ture in the presence of two subscribing witnesses.

FRANCIS HUPPERTZ. Vitnesses:

CARL LEI-IWALD, PETER J. FLAMMANG.
