THOMAS DONAHUE AND GEORGE N. WATERBURY, OFTERRYVILLE, CONN ASSIGNORS TO THE EAGLE LOOK COMPANY, OF SAME PLACE.

TRUNK-LOCK.

- SPECIFICATION forming part of Letters Patent No. 256,300, dated April 11, 1882.

I Application filed January 6,1882. (ModeL) I To all whom it may concern Be it known that we, THOMAS DONAHUE and GEORGE N. WATERBURY, both of Terryville, in the county of Litohfield a'nd State of.

Connecticut, have invented a new and useful Improvement in Truuk-Locks, of which the following is a full, clear, and exact description.

The object of our invention is to construct a hasp and look not liable to be broken or distorted, and especially adapted for use on large and heavy trunks.

The invention consists in a screw-acting lock and a hasp fitted to move without projection outward, and also in certain features of construction, as hereinafter described and claimed.

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

Figure 1 is a face view of the lock with the haspin its unlocked position. Fig. 2 is aface view with the hasp locked. Fig. 3 is a longitudinal section on line as m of Fig. 2. Fig. 4is a section on line y y of Fig. 2, showing the lock-bolt projected; and Fig. 5 is a perspective view of the lock-cylinder and filling-piece.

A represents the front portion of the trunkcover, to which the lock proper is attached, and B the bodyof the trunk, on which the hasp is fitted. The cover A is formed with a circular aperture, in which is a flanged screwcollar, a, inserted from the back. I) is the cylindrical lock-case engaging the collar a, and

formed with a flange, b, that takes against the face of cover A. A key, a,- inserted from the back between the collar a and case b, (see Fig. 3,) prevents the separation of thoseparts, h

and in order to retain the lock properly in place the flange b is formed with spurs that enter the cover, as shown in Fig. 4.

O is the locking-bolt, contained in an inner cylinder, 0, that is a portion of case b, and formed with a screw-thread on its inner end engaging a similar thread on the inner surface of cylinder 0, so that the bolt is moved in and out by turning it. In the case b are pins for entering holes in the bolt, which contains corresponding pins, the construction being that rection.

for engaging a similarly-formed recess in the hasp, next described.

E is the hasp, consisting ofa plate attached to the trunk B by a screw-bolt, g, having a flaring head that engages an undercut groove, it, formed in the under side of the hasp, whereby the hasp is free to slide on the bolt. Near the upper end of the hasp a pin, 2', projects from its under side for entering a slot in the plate 76, fixed on trunk B. This pin takes the slot as soon as the hasp is free from the locking-bolt, thereby preventing any side movement of the hasp on the bolt g,- but in the raised or locked position, the pin t being free from the slot, the hasp is not rigidly held and may move sidewise with the cover. The object of this is to prevent strain on the hasp from any racking movement of the cover on the trunk-body.-

In the upper end of hasp E is a slot,'l, which allows projection of the hasp upon the bolt 0 recessed to receive the flange snugly. On the bolt is a filling-piece, m, held by a ring, a, so that it may turn freely. This piece fills out the end of slot 1, that extends above the flange and, being loose, accommodates itself to the asp..

The operation is evident. With the'hasp raised and the-bolt U screwed in, the hasp is securely locked. To unlock it the key is inserted and the bolt given nearly a complete turn, which carries the flange f out free from the recess in the hasp, and the hasp drops or may be drawn down far enough to clear the cover whenthat is raised. The outward movement of the bolt is limited by stop-pin d engaging with the notches in the said bolt, and

the inward movement being limited by the 'with a screw and an outer flange, f, cylindrical case 0, provided with an internal screw and locking-pins and sliding hasp E, having a slot l, and recessed face, substantially as shown and described, for operation as speci- 2. In trunk-locks, the cylindrical lock-case I), provided with flange b, screw-collar (t, and key a, combined for connection to the trunkcover, substantially as shown and described.

3. In a trunk-lock, the combination, with the locking-bolt G and the sliding hasp E, provided with the slot 1 in its upper end, of the ringIn, provided jvith the filling-piece m, and fitted loosely upon the bolt, substantially as herein shown and described, whereby it is adapted to accommodate itself to the hasp and to fill out said hasp above the bolt, as set forth.

4. In a trunk-lock, the combination, with the looking-bolt 0, provided with the recesses e 0, cut away at one side, of the spring-pressed stop-pin d, engaging with the notches of the said bolt, substantially as and for the purpose set forth.

5. In a trunk-lock, the combination of hasp E, having slot h and pin 1', with bolt 9 and 0 slotted plate 70, substantially as shown and described.
