CHARLES A. TAYLOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO JOHN H. SESSIONS, OF BRISTOL, CONNECTICUT.

BOX-FASTENER.

SPECIFICATION forming part of Letters Patent No. 236,733, dated January 18, 1881.

Application filed August 31, 1880. (ModeL) To all whom it may concern:

Be it known that 1, CHARLES A. TAYLOR, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in TrunkBolts, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a front view of a trunk-bolt embodying my invention Fig. 2, a rear view of the same when the back plate of the lower part of the bolt is removed, and Fig. 3 a section in the plane of the line 00 m of Fig. 2.

Like letters of reference indicate like parts.

My invention relates to that class of trunkbolts employed in aid of the locks and arranged at the sides thereof, and usually upon the front of the trunk.

My object is to simplify and improve the construction and operation of bolts or fastenings of the class referred to and my invention consists in the means, substantially as hereinafter specified, which I employ for that purpose.

A represents a plate adapted to be applied to the lid of the trunk.

B is a hook or catch extending downward from the lower edge of the plate A, and .C is a guide, arm, or projection extending from the same edge and in the same direction, but somewhat removed laterally from the hook or catch B.

Dis a plate adapted to be applied to the body of the trunk. The plate I) is upset or raised, as shown at a a, to form a chamber or recess, a, between a portion of it and the trunk, as shown. Openings 1) and I) exist in the side walls, respectively, of the recess a.

E and E are studs or small posts extending inward from the face-wall of the recess a, and F is a back plate resting detachably on the said studs, and closing the recess a.

G is a bolt turning pivotally at one end on the stud E, and c is a hook-shaped projection on the upper or opposite end of the bolt G.

c is a projection extending from the bolt G toward the opening I), and d is a small pin or stud on the said bolt.

H is a rectangular bolt turning on the Stud (1, and having a hook-shaped end adapted to enter the opening I).

I is a spring bearing at one end against the lower end of the bolt H and at the other against the plate D, as shown.

The two parts or bolts G and H act together in the manner hereinafter explained.

In practice the plate A is to be attached to the lid of the trunk, and such a plate is arranged on each side of the lock proper, and two plates, D D, are correspondingly arranged on the body of the trunk, all in such a manner that the catches B B and guides C C will enter the upper ends of the recesses a a on closing the lid. The guides C C are not essential, but preferable. As the hook B, which is beveled, as shown, on its lower end, moves down into the chamber a it strikes the upper end of the bolt G, which is correspondingly beveled, and which, as before stated, is also hookshaped. The contact of these beveled surfaces during the closing of the lid causes the upper or hook-shaped part of the bolt G to move or yield as the hook B descends; but by the time the lid is closed the hooked end of the bolt springs to engagement with the hook B, owing to the action of the spring I, which is such as to cause that result, and to the fact that its action is not then resisted. The trunk will thus be automatically locked. The result now described will follow when the bolts G and H stand in the position indicated in Fig. 2, the hooked end of the bolt H being in the opening 1), but not engaging the plate D during the movement required to cause the engagement of the bolt G with the hook B. To unlock or disengage the bolt Cr and hook B, it will only be necessary to press lightly upon that part of the bolt G which projects into the opening I), and into which itprojects sufficiently to admit of such pressure being made with facility. This pressure, which is exerted laterally toward the plate D, carries the hooked end of the bolt G from its engagement with the hook B, and by the time the disengagement occurs the hooked end of the bolt H will move into engagement with the plate or case D, owing to the fact that the hooked end of the bolt H was carried laterally by the lateral movement of the bolt Gr and downward by the action of the spring I. During the engagement ot' the bolt H with the plate D the bolt G will be held from its engagement with the hook B, and consequently the lid will be free or unlocked, and may be raised and will not be locked automatically when closed or lowered.

In order to set the bolts either for automatically locking down the lid as the latter is closed or for looking it in its closed position after it has been lowered, it will only be necessary to raise the hooked end of the bolt H from its engagement with the plate or case D, whereupon the spring I will carry the hooked end of the bolt G to engagement with the hook B.

It will be perceived from the foregoing description and from reference to the drawings that I employ only one spring in connection with the bolts, and that the lid may be either locked automatically as it is closed, or afterward, by raising the exposed end of the bolt H. The bolts may be rendered inoperative upon the hook B by simplyleaving the exposed end of the bolt H in engagement with the plate or case D. It will also be perceived that these desirable results are accomplished by means of parts which are simple in their construction and operation. The back plate, though preferable, is not absolutely essential.

Having thus described myinvention, What I claim as new, and desire to secure by Letters Patent, is

The combination, in a trunk bolt or fastening, of the plate A, having thereon the hook or catch B, the plate D, having therein the recess a,open at its top and sides, the pivoted bolt G, adapted to engage the catch 13 and to extend into one of the said side openings, the bolt or catch H, pivoted to the bolt G and adapted to engage the plate D through the other of the said side openings, and the spring I, substantially as and for the purposes specified.
