HIRAM L. MACE, OF EAST DURHAM, NEW YORK.

LOCK.

SPECIFICATION forming part of Letters Patent No. 666,765. dated January 29, 1901.

Application filed November 9. 1900- Serial No. 35.903. (No model.)

1'0 aZZ whmn it may concern.-

Be it known that l, HIRAM L. MACE, of East Durham, in the county of Greene, in the State of New York, have invented new and useful Improvements in Locks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in looks, and is particularly applicable for use in connection with mail or express pouches, trunks, grips, &c., but may evidently be applied to doors and other closures, if desired.

The objects of this invention are, first, to produce a simple and practical lock in which the locking bar or member is yieldingly held in its locking position and may be movediby hand to its inoperative position when desired; second, to so construct the lock-bar that a hasp or other member may automatically interlock therewith, and, third, to provide a keyactuated tumbler which is movable into and out of the pat-h of the lock-bar and is held in its adjusted position by the same spring which yieldingly holds the lock-bar in operative position.

To this end the invention consists in the combi nation,construction, and arrangements of the parts of a lock, as hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Figure 1 is an isometric view of a lock embodying my invention. Figs. 2 and 3 are plan views of the interior mechanism of the lock seen in Fig. 1, the tumbler being shown in its operative position in Fig. 2 and in its inoperative position in Fig. 3 and the lock-bar being indicated by dotted lines in its inoperative position at Fig. 3. Figs. 4 and 5 are sectional views taken, respectively, on lines 4 4 and 5 5, Fig. 2.

Similar reference characters indicate corresponding parts in all the views.

This invention consists, essentially, of a frame 1, a lock-bar 2, spring 4.

The frame 1 may be of any desired form, size, or construction and when used in connection with a pouch, traveling-case, or similar device preferably consists, as seen in the drawings, of a base-plate 5, side and

end walls

6 and 7, projecting from the base-plate, and an outer wall 8, uniting the outer edges of the a tumbler 3, and a

walls

6 and 7. The plate 5 is suitably secured to any desired form of device requiring a lock and is usually provided with an opening 9 for receiving a locking member, as a hasp a, which is adapted to interlock with the lock-bar 2. Although I have shown the outer wall 8 as provided with asimilar opening 11, alined with the opening 9 and adapted to receive the projecting end of the hasp a, 'it is evident that this opening 11 may be dispensed with and the hasp or other interlocking member made to conform to such a condition.

Journaled in the

plates

5 and 8 is a keybarel12, having a keyway 13, adapted to register with a keyway or recess 14, formed in the tumbler 3. One of the end walls 7 of the frame 1 is formed with an opening 15, whichis arranged to receive an extension of the lock-bar 2for a purpose presently described. The lock-bar 2 may also be of any desired form or size, and preferably consists of a rock-lever pivoted at 16 to the frame 1 between the

plates

5 and 8 and having one end provided with a shoulder 17 movable across the opening 9 and its other end extended through the opening 15 and provided with a suitable hand piece 18. The face of the shoulder 17 adjacent to the plate 5 and opening9 is generally inclined or cam-shaped for permitting the hasp a to be readily inserted into the opening 9 and automatically interlocked with the shoulder 17. The other end of the lockingbar 2 is preferably formed with a laterally-projecting arm 20, which serves to normally close the opening 15 and prevents the insertion of any instrument whereby the tumbler or other members might be tainpered with.

The tumbler 3 is interposed between the walls of the frame 1., is reciprocally movable into and out of the path of the lock-bar 2 for locking said bar in its operative position when desired, and generally consists of a substantially flat bar having one of its longitudinal edges bearing against the inner face of one of the walls 6 and its opposite edge provided with

recesses

14, 21, and 22, arranged one in advance of the other, and with a stop-shoulder 23, adapted to engage a stop-pin 2% for limiting the movement of said tumbler to its operative position. The end of the tumbler adjacent to the lock-bar 2 extends beyond the st-op-shoulder23, is formed of substantially the same width as the distance between the stop-pin 24 and the adjacent wall 6, and is movable between said wall 6 and the adjacent face of the lock-bar 2 for holding the lock-barin its locked position, with the shoulder 17 across the opening 9, it being understood that the distance between the adjacent faces of the inner end of the lock-bar and wall 6 is substantially equivalent to the width of the adjacent end of the tumbler, and that said inner end of the lockbar is prevented from further separation from the adjacent wall 6 by the engagement of the outer end of the lock-bar with the end wall of the opening 15, said opening being of sufficient length to permit the shoulder 17 to be drawn or forced out of alinement with the opening 9 when the tumbler is moved to its inoperative position for releasing the hasp a.

In order to hold the tumbler 3 in either of its adjusted positions, I provide the frame 1 with a suitable guide 25, which generally consists of a slot formed in a pin 26, projecting inwardly from the base-plate 5, and in which is reciprocally movable a yielding shoulder or plunger 27 for successively entering the

recesses

21 and 22. The adjacent walls of these

recesses

21 and 22 are preferably inclined toward each other to permit the tumbler to be readily moved into and out of operative position by a suitable key operat ing upon the walls of the recess 14, as previously stated.

The spring 4 serves to automatically force and hold the lock-bar in its locked position and also to force the plunger 27 into the

recesses

21 and 22 for holding the tumbler in either of its adjusted positions, said spring being tensioned between the lock-bar and plunger and the adjacent wall 6 of the frame. This spring is preferably arranged with its intermediate portion bearing against one of the walls 6, one end being engaged with the adjacent edge of the outer arm of the locklever and the other end being secured to the plunger 27, and it is therefore apparent that a single spring serves to retain the tumbler in either of its adj Listed positions and to automatically hold the lock-lever in its locking position, capable of being moved to its other position by the handpiece 18 when desired.

The advantages of the lock above described are obvious. For example, when it is necessary to frequently open a pouch, case, or

other structure equipped with my'improved lock and to have the same closed. and locked during the intervals it is simply necessary to withdraw the tumbler from operative position, whereupon the lock-lever may be readily rocked toits inoperative position, which looklever automatically returns to its normal position when released, and the hasp automatically interlocks with the shoulder 17 when the hasp and lock are brought together.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that considerable change may be made in the detail construction and arrangement of the parts of this invention without departing from the spirit thereof. Therefore I do not limit myself to the precise construction and arrangement shown and described.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A lock comprising a frame, a lock-lever,

a reciprocally-movable tumbler having shoulders arranged one in advance of the other, a guide, a plunger movable in the guide for successively engaging the shoulders, and a spring having its intermediate portion hearing against-a portion of the frame and its opposite ends engaged respectively with the lockbar and plunger for the purpose described.

2. A look comprising a frame having a keyway and openings, a lock-lever having one end formed with a cam-faced shoulder movable across one of the openings and its other end extended through the other opening and provided with an arm normally closing the latter opening, a tumbler reciprocally movable between one of the Walls of the frame and the lock-lever for holding the shoulder in its locking position, said tumbler being formed with recesses disposed one in advance of the other, a key for engaging the walls of one of the recesses for moving the tumbler, a guide, a plunger movable in the guide for successively entering the other recesses, and a spring tensioned toward the lock-lever and tumbler and havingits opposite ends engaged respectively with the lock-lever and plunger for the purpose described.

In witness whereof I have hereunto set my hand this 29th day of October, 1900.

HIRAM L. MACE.
