SPECIFICATION forming part of Letters ratent No. 622,676, dated April 11, 1899.

Application filed November 22, 1898. Serial No. 697,209. (No model.)

.To all whom t may concern."

Be it known that I, JOHN M. FORNEY, a citizen of the United States, residing at Nisbet, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Combined Bolt and Lock, of which the following is a specification.

My invention relates to bolts for securing doors, and more especially to an improved arrangement of a bolt of this class and means for locking it in its forward or closed position.

The object of the invention is to "provide means whereby the ordinary bolt may be used for its usual purpose and operated by hand to either lock or unlock it and by which when desired the bolt may be locked with a key.

1 My invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward speciiicall y pointed out in the appended claims.

In order to enable others skilled in the art 'to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings,formin g part of this speciiicatiomin which Figure 1 is a perspective view illustrating a combined bolt and lock constructed in accordance with my invention in practical use. Fig. 2 is an interior view of thelock-case, looking from the front, with the front plate removed. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4e is a similar section on the line l 4t of Fig. 2. Fig. 5 is a detail perspective view of the locking tumbler or latch detached.

Like letters of reference mark the same parts wherever they occur in the various iigures of the drawings.

Referring to the drawings by letters, A indicates a round bolt of ordinary construction, mounted in a barrel B, the 4barrel being pro-= vided with the usual longitudinal slot O,with end branches D and E at right angles thereto, extending partially around the barrel, through which slot the laterallyprojecting handlebar F of the bolt extends and by which the bolt may be operated by hand, as is usual.

The laterallyextending arm or handle F in this instanceis provided with an angular arm F at its outer end, formed into a catch F2, adapted when the handle-bar is turned into the branch slot D to retain the bolt in its 'locked position in the keeper G to enter an is held normally upon the bottom plate of the lock-casing by means of a spring M, consist-4 ing of twoarms joined by acentral coil, which coil is mounted upon a stern N, projecting inwardly from the back plate of the lock-casing, and held in position thereon by a screw O, the upper arm of the spring resting against the under side of the top plate of the lockcasing and the lower arm resting upon the upper edge K' of the latch, which is widened to provide a proper seat therefor, as shown most clearly in Fig. 5.

The hub L of the latch K is hollow at. its front end and is provided with an angularshaped pintle or lug P to receive a key, by which it may be turned, and the outer lower edge of the latch is out away to permit of the entrance of the catch F2 into the lock-case. A flat spring Q, secured to the rear plate of the lock-case, projects downward inline with the cut-away portion of the latch K, and when the catch F2 is within the lock-case the normal tendency of this spring pressing against the inner face of the latch is to throw the latch out of the case.

With a bolt and lock constructed as hereinbefore described the bolt may be operated in the usual manner by using the bar F as a handle to press the bolt forward and backward, the handle moving in the slot C and its branches D and E; but when it is desired to lock the bolt so that it cannot be removed The latch when in opera-` l tive position to receive the catch F2 rests and from the keeper G without the key the bar F is pressed inward in the branch slot D until the catch F2 enters the opening I-I in the lock-case and wedges its way under the latch K, which by Virtue of the tendency of the spring N will immediately drop behind the point of the latch F2 and securely hold the latch and handle-bar against being withdrawn from the casing. To unlock the bolt, a key provided with a bore corresponding in contour with the pintle P is inserted in the hub of the latch over said pintle and turned, raising the latch K out of engagement with the point oi' the catch F2, which, being then free, will be pushed out of the casing by means of the spring Q.

The advantages attending the use of my invention will be obvious from the foregoing description, and while I have illustrated and described the best means nowr known to me for carrying out my invention I do not wish to be understood as restricting myself to the exact details of construction shown, but hold that any slight changes,such as might suggest themselves to the ordinary mechanic, would properly fall within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to'secure by Letters Patent of the United States, is-

l. The combination with a bolt mounted to rotate and slide in a barrel or casing and provided with a lateral handle-bar projecting through a slot therein, said handle-bar being bent inward toward the back plate and formed at its end into a latch, of a spring-actuated latch or tumbler, a casing in which said latch is pivoted, provided with an opening to permit the catch to enter and engage under the spring-latch, and a spring, secured within thev casing and bearing against the inner end of the catch to push it out of the casing when released from engagement with the latch, substantially as described.

2. The combination with the back plate, J, of the lock-casing and bolt-barrel mounted thereon, the latter being provided with the longitudinal and branch slots, the bolt,mount ed in the casing, the laterally-projecting handle-bar, F, of the bolt, adapted to move in said slots .and having its outer end bent to form the catch, F2, the latch, K, pivotally mounted in the lock-casing and adapted to be turned with a key, its lower, outer corner being cut away to admit of the entrance of the catch into the casing, the spring, M, coiled around the stem, N,- inside the casing, having one of its arms bearing upward against the top of the casing and the other downward against the top ofthe latch,and the fiat spring, Q, secured to the back plate, J, and bearing outward against the inner end of the catch, substantially as described.
