To all whom 'it may concern:

j Be4 it known that I, HARRY M. LEESE, a citizen of the United States, and a resident of Vashington, in the District of Columbia,

certain new and useful Improvements in Locks, of which the following is a specification.

This invention is an improvement in locks and is la division of a former application No. 529,287, filed by me November 22, 1909 for improvements in desks; and the invention consists in certain novel constructions and combinations of parts whereby the rocker may be locked from movement and whereby the key mechanism for unlocking the rocker may be utilized in turning the rocker in securing the operation of the parts as desired.

In the drawing Figure 1 is a sectional front elevation of a portion of a desk provided with my improved lock. Fig. 2 is a detail section through the rocker and its locking means, the key being shown in side elevation. Fig. 3 is a detail perspective view showing parts of the lock detached. Fig. 4 is a cross section on about line 4-4 of Fig. 2. Fig. 5 is a detail perspective view showing a rocker having one arm instead of two.

I have shown my lock in connection with a desk, which desk may, in general respects, be of ordinary construction and in the construction shown in Fig. 1 is a roll top desk having a slatted cover A and drawers B in vertical tiers on opposite sides of the center of the desk. My improved lock is shown as supported on the slatted cover midway between its ends and as described in my said application 529,287, the lock has its rocker formed with a barrel C having arms C to which are connected the rods C2 which extend thence in opposite directions and connect with levers C3 which are pivoted at their upper ends and connect with the rods C2 between their ends, with the lower ends of the levers C3 operating upon bearings D provided at the upper end of slide rods D so that the adjustment of the rocker to the position shown in Fig. 1 will depress the slide rods into position to lock the drawers and the said rods will be lifted by their springs D3, which bear below them when the levers C3 are moved out of engagement with the slide rods by the turning of the rocker. The levers C3 are provided with spurs or projections C* which move when the parts are in the position shown in Fig. 1 into engagement with spring actuated bolts E in such manner as to lock the cover A in closed osition so long as the rocker is in the position shown in Fig. 1. Manifestly other applications of the rocker may be availed of without departing from some of the principles of my present invention which relates particularly to the locking mechanism comprising the rocker which may have one arm as shown in Fig. 5 or two arms as shown in Fig. 3 and is formed with a barrel C having a slot C10 to receive the key F and at its rear end the barrel C has an angular socket C11 to receive an angular bolt G when the latter' is projected by its spring G as shown in Fig. 2 of the drawing. The bolt G is tted in the casing G2 secured to the cover A or other support by meansof the arms G1"v deflected at G11 so the ears G12 may be secured directly against the support and the body of the casing G2 will be spaced away from said support, sufticiently to permit the o eration of the rocker as will be understoo from said Fig. 2. In the operation of this construction, it will be noticed that when the bolt G is projected as shown in Fig. 2 into the angular opening C11 of the operating device or rocker, it will lock the said rocker from turning whether the same be in the position shown in Fig. 1 wherein the slide rods are locked or whether said rocker be in unlocked position. The key F is arranged at its inner end F to engage with the outer end of the bolt so that in inserting the key it will first push back the bolt G and release the rocker so the latter can be turned by the action of the key.

In the special construction shown, it will be noticed that the barrel C has an inwardly projecting portion C15 which is concentric with and telescopes with the meeting end G15 of the lock casing G2. In the construction shown, the extension C15 of the barrel fits within the end G16 of the lock case G2 and is supported and guided thereby.

A suitable escutcheon C5 may, in practice, be provided as shown in Fig. 3 and be supplied with the key hole slot Cc as shown in said figure.

It will be noticed that the bolt G is movable in the direction of the axis of the rocker into and out of engagement with said rocker filed May 'shank F2 to lock the same and that the. casing of said bolt forms a bearing for the barrel of the rocker.

It Will be noticed especially from Figs. 2 and 3 that the escutcheon C5 is chambered yfrom its rear side at C7 and the barrel C -ts at its outer end in said chamber C7 and `at its inner end Within the adjacent end of the casing G2 so that the rocker is securely supported and braced i-n position, both front and rear of the rocker arms. v The key F it will be noticed has a reduced and is provided with Wings or. blades F3 corresponding to the .slots C16 eX- tending from the central opening CG in the escutcheon and also With the Wings in the head of the barrel portion of the rocker so that the key can only operate to release the bolt G when formed tocoincide With the slotted formation of the escutcheon and barrel head as before described. i

I claim:

l. The herein described locking device comprising a rocker having its barrel provided with a key hole slot and with an eXtension, said barrel being also provided with a non-circular opening for the reception of a locking bolt, a spring actuated locking bolt moving into and out of said opening, a casl lng for said bolt having surrounding, the Y bolt, a bearing for the barrel of the rocker, said casing being also provided With lateral arms having offset portions adapted for connection with a support, all substantially as and for the purposes set forth.

2. A locking device comprising a rocker having' a rock-er arm and a barrel provided in front and rear thereof with cylindrical portions, an escutcheon having a chamber receiving one of said cylindrical portions, af

t. A locking device comprising. a rocker, l

a bolt for locking the rocker and movable longitudinally in the axial line of the rocker, a casing for said bolt having means forming a bearing for the rocker, and lateralv arms on said casing having offset portions adapted for connection with a support, substantially as and for the purposes set forth.
