ROBERT C. SCHENCK, JR., OF DAYTON, OHIO.

CARI-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 335,778, dated February 9, 1886` Application filed September 12, 1885. Serial No. 176,864.

To all whom t may concern):

Be it known that I, ROBERT C. SoHENoK, .I r., a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Car-Door Locks, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My improvement relates to car-door locks composed of a staple and a corresponding hasp fitting thereon, and provided with a gravita-ting latch, whereby when the hasp is fitted over the staple the gravitating latch piece falls to such a position that the hasp becomes at once self-locked upon the staple.

The novelty of ny invention will be herein set forth, and specically pointed ont in the claims.

In the accompanying drawings, Figure l represents a front elevation of my improved lock as applied to a car, showing the door locked entirely shut and sealed. Fig. 2 is a central sectional view of my improved lock through the staple-plate and latch-piece.

The same letters of reference are used to indicate identical parts in both the figures.

A represents a staple-plate attached to the side of the car B, and provided with a projecting and preferably integral staple, C, over which. lits the hasp D, which is attached to the corresponding door, E, in the usual or any suitable manner.

Upon the staple C is loosely pivoted a gravitating latch-piece, F, which is made heavier at one end, so that it always hangs in a substantially perpendicular position.

The position of the staple and hasp above described may of course be reversed-that is, the hasp may be hinged to the car and the staple be attached to the door. When it is The (No model.)

or may be locked ajar for the purpose of ventilation.

YVhile I prefer the form illustrated,wherein the upper portion of the latch-piece is hollowed out, as shown, yet I do not limit myself to the details of form, but consider as the es-' sence of iny invention the combination, with a preferably solid staple-piece, of a gravitating latch pivoted thereto and adapted to swing across the hasp to hold the same locked against outward strain.

It will be observed that the ordinary and normal strain is borne directly by the staple O, and not by the gravitating latch.

I-Iaving thus fully described my invention, I claiml. The combinatiomwith a hasp, of a staple over which the hasp fits and with which it engages, and a gravitating latch pivoted to the staple and arranged to automatically swing across the hasp to hold the same locked, substantially as described.

2. The herein-described car-door fastening, consisting of the perforated hasp D, staple plate A, having a staple, O, secured thereto, a gravitating latch, F, pivoted to the staple C, and a bracket, G, projecting from the plate A, said latch and bracket being coincidently perforated to enable a locking-wire or padlock to be passed therethrough, the whole constructed in the manner and for the purpose specified.
