UNITED STATES PATENT OFFICEo FBIEDRIK BECKER, OF SURANTON, BENNSYLVANIA.

IMPROVEMENT IN SECURING SVHUT'VI'ERS AND SHOW-WINDOWS.

Specification forming part of Letters Patent No. 37,849, dated March l0, 1963.

To @ZZ whom it may concern:

Be it known that I, FEED. BECKER, of Scranton, in the county of Luzerne, State of Pennsylvania, have invented a new and Improved Mode ot' Securing Shutters on Show- Windows, &c.; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, with letters of reference marked thereon.

The nature of my invention consists of securing shutters, &c., by means of catches C, which are governed by asimple apparatus located inside ofthe show-case.

The drawing represents the apparatus iu a state to remove the shutters, as will be perceived by the closure of the catches C.

rlha way how to secure the shutters by the apparatus D would be as follows: In turning the handle A one-quarter of its circle in the diiection X, the spiing B, which is in the f0r mer-mentioned position, (it is expanded) iinmediately after the motion, will retire and cause by this move a united opening of all catches U attached to the apparatus or pool D. These catches G are so constructed that the part m. ot' each catch C is connected by means of a screw, o, to the pool D, which is the communication between the handleA and spring B. The pool l), governed either by handle A or spring B, will cause the part d of each catch to act upon the part e of each catch, on account of their eccentrical axles creating such a closure. catches opened by way as above mentioned, they are now ready to receive the shutters. The shutters have on the top an extension, which will be put irst into a little hole corresponding, pressing the lower part. In doing so the shutters will be pressed against the catches. The catches will slip into an opening, E, be pressed together, and expand again by means of the spring B. The. shutters are now unremovable from the outside. By turning the handle'A again to the right, about a quarter otl a circle, the catches C will close together, and the shutters will be able to be removed.

'lhe shutters are provided on the lower part with a little india rubber block, to prevent sliding.

What I claim as my invention, and desire to secure by Letters Patent, is-

The mode of securing the shutters by means of the peculiar constructed catches C, governed by the apparatus, as above described, and shown in the drawings.
