SPECIFICATION forming part of LettersPatent No. 447,664, dated March 3, 1891.

Application filed November 6, 1890. Serial No. 370,467- (No model.)

T0 to whom it may concern:

Be it known that I, ANTHONY CLARK, a citizen of the United States, residing at Parkersburg, in the county of \Vood and State of West Virginia, have invented newand useful Improvements in Seal IIasp-Locks, of which the following is a specification.

This invention has for its object to provide a novel, simple, eiiicient, and economical seal hasp-lock of such construction that the parts are preserved in correct locking position and even though the door and door-frame expand or contract. To accomplish this object my invention involves the features of construction, the combination or arrangement of devices, and the principles of operation hereinafter described and claimed.

To enable others skilled in the art to understand and practice my said invention, I will proceed to describe the same in detail, reference being had to the accompanying drawings, in which Figure 1 is a face view or elevation of a car and car-door equipped with my invention. Fig. 2 is a detail perspective showing the metallic portions of the lock, the same being shown in their normal relations to each other.

In the said drawings, the reference-numeral 1 denotes the door-post or part' of the doorframe of a car or other similar structure,

Set within a suitable recess in the door-post or frame 1 is a metallic plate 3, preferably formed of steel and having any preferred shape, the form shown being rectangular. This plate is secured within its recess by bolts 4, and through the same pass the arms of a staple 5, which may penetrate the plate and be riveted upon the rear face thereof, or, if preferred, may pass entirely through the doorpost and be secured in any preferred manner.

Upon the door 2 is mounted the hasp-plate 6, consisting of a metal plate of suitable thickness having an eye 7 at one end which engages an eye 8 in a bolt 9, passing through one of the beams or braces of said door. At its other end this plate 6 is provided with a slot 10, which is adapted to engage the staple 5, the length of said slot being in excess of the width of the staple.

Upon the hasp-plate 6 is mounted a pivot 12, having a flat head 13, and upon said pivot is mounted a locking-plate 14, having an elongated slot 15, which receives the pivotpin, whereby a longitudinal movement or adjustment of the locking-plate upon said pin is permitted. Upon its end which lies adjacent to the locking end of the hasp-plate is formed a depending bolt 16, which may be engaged with or disengaged from the staple 5 by entering or withdrawing it from the same, the slot 15 permitting a sufficient 1ongitudinal movement to permit this engagement and removal. Immediately above the point of union between the said bolt and the locking-plate is formed an outwardly-proj ecting lug 17, having -an opening 18, said lug resting upon the staple in such position that the wire or wires of the seal may be passed through its opening and through the staple 5. The wire is then passed through the lead or other seal 19, with which they are connected permanently in any manner preferred. It will be observed that by this construction I not only provide a strong and simple lock which cannot be tampered with without destroying the seal, but I also make ample provision for a perfect fit of the hasp-plate over the staple and the engagement of the lockingplate with the latter under any shrinkage or expansion of the car-door or of the doorframe. Moreover, the slot in the lockingplate permits the longitudinal movement of the latter upon the pivot-pin on the haspplate, whereby the straight or substantially straight bolt 16 may readily be withdrawn from and re-engaged with the staple 5.

What I claim is A seal hasp-lock consisting of a staple, a hasp-plate having at one end a slot for the passage of the staple, and alocking-plate having a pin and elongated slot connection with the hasp-plate and provided with a pendent bolt, and alateral lug arranged in juxtaposition to the bolt and having an orifice therethrough for the passage of a seal-wire through the lug and the staple, whereby the bolt cannot be lifted from the staple without breaking the seal, substantially as described.

In testimony whereof I have hereunto set my hand and affixed my seal in presence of two subscribing witnesses.

ANTHONY CLARK. [L. s]
