SPECIFICATIQN farming part of Letters Patent No. 321,628, dated July .7, 1885.

Application filed September 15, 1884.

To aZZ whom it may concern:

Be it known that 1, CHARLES R. NnLsoN, of the city, county, and State of New York, haveinvented a new and Improved Box-Fast ener, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for fasten ng and securing covers on boxes, which device permits of fastening or unfastcning the covers very rapidly.

The invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of the boy fastener. Fig. 2 is a vertical cross-sectional view of the same. n

On each end of the cover A a saddle, B, is secured on the upper surface, which saddle is provided on its upper surface with two transverse ridgcs, between which the upper bent end, G, of a clamp-plate, O, can be passed, the said clamp-plate being provided in its lower end with an aperture, F, for receiving a tubularinternally-screw-threaded projection, I), on a plate, E, secured transversely on the outer surface of the corresponding end of a box.

The clamp-plate C is widened at the lower end or provided with laterally-projecting lugs G, which are adapted to catch on lugs I, pro

5 jecting from the outer face of the plate E.

These lugs I, in connection with the transverse ridges on saddle B, prevent any lateral movement whatever of the clamp-plate when said plate is in its locked position.

The clampplate O is provided with ribs H on the inner surface along the side edges, which ridges are to rest against the outer surface of that end of the box to which the plate E is secured. The plate E is not mortised, but is placed against the outer surface of the end of the box and held on it by screws. The tubular screw-threaded projection D on the plate E takes all strain from the screw L, and the vertical strain on the said projection D is relieved by the lugs I, which receive through the lugs G of the clamp a portion of the strain. Bibs m are formed on the outer surface of the (X0 model.)

plate C. These ribs m are for the purpose of imparting additional strength to the clampbar 6 atits perforated end, where, of course, it is weakest:

The ribs H are provided with offsets h at the lower ends, which offsets rest against the upper edge of the plate E.

When the plate G is not provided with ribs H, the said plate must be provided with the offset h. The purpose of providing the'offset is to have the upper part of the inner surface of the plate 0 or of the ribs H flush with the inner surface of the plate E.

The aperture E is flared toward the inner end to permit swinging down the clamp-plate 0 parallel with the end of the box when the cover is to be removed. A screw, I), having a head, L, is screwed into the tubular projection D.

To fasten the box the plate (J is swung up and moved toward the end of the cover until the part 0 rests upon the saddle B, and then the screw L is drawn up tightly.

I am aware that a saddle having transverse ribs has been placed on the upper surface of the end of a box-top, and that a clampingplate was secured to a mortised attachingplate on the end of the body of the bOX by a long peculiarly-formed screw. The upper end of the clampingplatc was bent so as to rest between the transverse ridges of the saddle when in alocked position. I do not claim any such construction as of my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a box-fastener, the combination, with a clampplate having an aperture in one end, of a plate adapted to be secured on the box, and provided with an internallythreaded tubular projection, which is passed through the aperture in the clamp-plate, and a screw for holding the clamp-plate on the tubular projection, substantially as herein set forth.

2. The combination, with a clamp-plate having an offset, it, and an aperture at its lower end, of the plate E, having lugs I, on which lugs on the clamp-plate can catch, and a screw passing through the aperture in the clamp into the plate E, substantially as herein shown and described.

3. The combination, with the saddle B, hav- ICO ing transverse ridges, of the plate E, having an internally-threaded projection, D, and lugs I, the angular clamp-plate 0, formed with the aperture F, and lugs G on opposite sides thereof, and the screw L, for clamping the parts in place, whereby when said parts are in place on a box all lateral movement will be prevented by the lugs I and ridges on the saddle, and the strain be equally distributed between them, substantially as set forth.

4. In a box-fastener of the character described, the clamp-plate 0, having an aperture, F, and the ridges m on opposite sides of the aperture for imparting additional strength to said perforated part, substantially as set forth.

CHARLES R. NELSON.
