ARTHUR C. FRINGE, OF CHICAGO, ILLINOIS.
LOCK.
Application filed February 21, 1921. Serial No. 446,689.
ToaZZ whom it may concern Be it known that l, ARTHUR C. PRINCE, a citizen of the United States, residing at Chicago, in the county of look and State of Illinois, have invented a certain new and useful Improvement in Locks, of which the following is a specification.
My invention relates to an improvement in looks, and has for its object to provide looking or securing means whereby a door, or the closure of an aperture may be locked to the door frame or the aperture in which it lies, at a plurality of opposed points, and by the same locking operation.
I illustrate my invention as applied to a closure for a small bank, but it is obvious that it mightbe used in the doors of safes, pay telephones, slot machines, and any other such closures, of various sizes, which are subjected to the likelihood of frequent tainpering.
l illustrate my invention more or less diagrammatically in the following drawings, wherein:
Figure 1 is an elevation of a bank, to which my invention is applied;
Fig. 2 is a vertical section on an enlarged scale, on the lines 2-2 of Fig. 1;
Fig. 3 is a view of the lid, with parts cut away showing the locking mechanism.
Fig. at is the side elevation of Like letters and numbers represent like parts throughout the drawings.
A is a bank body illustrated and shaped like a small barrel, the bottom of the barrel being slotted, as at B, for admission of the coins to be kept therein. The sides of the slot are upturned within the bank, as at C, C, to provide inwardly projecting flanges on either side of the slot.
Fittingly closely within the opposite end of the body is the cap D which has an inwardly projecting rind E adapted to engage the edge of the bank body F, and inclose the locking mechanism. The cap is perforated at diametrically opposed points, as at G and H, the perforation G being substantially circular and the perforation H being oval or otherwise elongated. Lying within the cap is the hollow cylinder 1., centrally screw threaded to receive the screw J and having a plurality of projections L L, adapted to penetrate the aperture H, leaving a space "between them suflicient for the penetration of the key M. l The screw N is composed of the bank lid.
a screw threaded body Qadapted to penetrate the screw threaded interior of the cylinder l, which is shaped to receive the key or socket wrench M. The opposite end of the screw comprises head P preferably rough ened or knurled, which is adapted to penetrate the aperture G, when the screw is rotated in the proper direction. Compressed between the rim of the cap and the cylinder H, is the spring Q adapted normally to force it in the direction of the aperture G. The body of the bank, adjacent the cap is surrounded by a projection or corrugation R which serves a lock or socket to receive the locking members L L, and P, when the screw is rotated in the proper direction to force their extension. The bankbody is perfor ated as at S to permit the insertion of the parts, without departing from the spirit of my invention.
The leaf spring might be replaced by a spiral spring, surrounding the interior locking cylinder. The locking end of the screw might be modified in form and might engage a small cup shaped aperture rather than the corrugation shown, and a multitude of minor mechanical changes might be made, to adapt the invention to doors or lids of other sizes and shapes.
The use and operation of my invention are as follows 1 illustrate a locking means which is particularly adapted for small banks. When the lid is inserted into the bank and the key is passed through the aperture in the bank body into the center of the locking cylinder and is rotated in the proper direction, the result is the extension of the screwthreaded locking pin, which presses against the opposed side of the bank. As the extension continues, and since the sides of the bank are rigid, the locking cylinder into which the pinis screw-threaded, is forced, against the resistance of the spring, in the opposite direction, its locking members are forced through the opposed aperture and into locking relation with the corrugation about the bank.
-lWhen the screw-threaded locking pin is in normal position, withdrawn into the cylinder, the spring keeps the opposed locking members out of contact with the bank body, leaving the closure unlocked. When the combined length of the cylinder and screw is increased by their relative movement,-
caused by the rotation of the screw, the spring yields to permit the projection of the locking members'or the cylinder. But since it does not yield until the endoi the screw begins to press against the side of the bank, it insures that at least one locking member will be in place, even though the locking rotation is not completed.
The pressure or" the spring and the nurling of the screw endinsure strong, frictional contact with the side of the banlnwhich will not be affected by rattling or picking at the bank. I I
When the locking rotation is completed, the cap is firmly clamped within the bank, and only the actual destruction of the upper part of thebank will permit the locking members to release their hold, since their combined length is actually greater than the diameter of the opening at the top oi the bank.
The slot at the bottom of the bank, which could of course, be made in the side of the bank, if desired, is surrounded by an upturned edge whlch makes removal of the coins by shaking the bank practically impossible. .To be shaken out the coin must hit the slot, or rather the acket formed by V the inward projection about the slot, at eX- 'actly the right angle, and there is relatively small chance of any coin so escaping.
