To (all who/1t may concern:

Be it known that 1, Homer; L. IIEATON, a citizen of the United States, and a resident of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improven'lents in Looks for the Meeting-Rails ot' Sashes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, rel'erence being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of two nieeting-rails of two windowsashes provided with my improved lock. Fig. 2 is a similar view showing the lock without the overlapping-base )lates. Fig. 3 is avertical section of the lock and rails. Fig. 4 is a view of a slight modification of the casing for the portion of thelock secured upon the meeting-rail of the lower sash; and Figs. 5, o, 7, 8, and f) are perspective detail views of the overlapping base-plates and of the several parts of the lock.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of locks for the meeting-rails of window-sashes in which a weighted bolt is pivoted at its upper end in a casingnpon the rail of thenpper sash, adapted to bear with its lower outwardlyswinging end against a shoulder upon the rail of the lower-sash, upon the upper side of which sash is pivoted a lever bearing with its end against the swinging bolt, adapted to push it back when tilted; and it consists in. the iniproved construction and combination of parts of such a lock and of parts of its baseplates, as hereinafter more fully described and claimed.

In the accompanying drawings, the letlerA indicates the meetingrail of the lower sash, and B the rail of the upper sash. A plate, 0, is secured upon the upper side of the rail of the upper sash, projecting slightly over the inner edge of the same, and is provided upon its upper side with two projections, I), having their outer sides, E, beveled and provided upon its middle with a long projection or ridge,

F, between the projections at a short distance from the edge. A easing, G, open upon its inner side, is secured upon the plate between the beveled projections, and a gravitatin g bolt, H, is pivoted at the upper corner of its inner open side, which bolt has aweighted portion, I, within the casing, which weighted portion forces the lighter portion J outward out of the casing, and the exposed side K of the bolt is beveled or inclined,while the boltformsastep or lip, M, at its lowermost end, which bears against the long projection F upon the baseplate. The upper side of the rail of the lower sash is provided with a plate, N, having at its edge which reaches over the edge of the rail 6 of the upper sash two hooked projections, O, which hook over and rest upon the beveled projections upon the plate of the upper sash, and upon its middle the plateis provided with two upwardly projecting lips, I, between which a lever, Q, is pivoted, the inner arm, 1%, of which is curved to form a handle, while its outer arm, which is curved slightly upward, projects within the lips when the inner arm of the lever rests upon the upper side of the 7- rail, while when the inner arm of the lever is raised its outer arm will project out be yond the edges of the lips and bear against the inclined side of the pivoted bolt, pressing it into its ease, allowing the lower sash c to be raised. The lower corner of the pivoted bolt forms a hooked projection, T, which engages the upwardly-projecting end of alever or catch, U, pivoted under the boltoperating lever and having its inner end pro- 85 jecting under the inner end of the latter, projecting with its upwardly bent outer end through a perforation in an inclined plate, S, between the lower ends of the lips P; and it will. be seen that the bolt-operating lever can- 0 not force the bolt back until the catch has been released by raising itsinner end, disengaging it from the hooked projection upon the bolt. It will be seen that this catch will prevent the sash from being raised by simply raising the lever, and the catch being partly covered by the lever it will not be easily observed by children or persons unacquainted with its construction, rendering it useful in nurseries or places where 1t is desirable to prevent tamper- I Q Somme ing with the sashes. It will also be seen that the overlapping base-plates will prevent the bolt from being pried open by a flat instrumentsuch as a knife-being inserted from below and from outside between the sashes, and that the beveled proj ections and thehooked lips will serve to hold the meeting-rails together,preventing them from rattling and from separating so far as to allow draft to pass between them.

' In Fig. 4 of the drawings a modification of the shape of the lips between which the lever is pivoted is shown, the inner edges of the said lips being extended beyond the outer edge of the base-plate, so as to rest upon the base-plate upon the upper sash, as shown at V, the said projections bearing upon both sides of the eas ing in which the lock is pivoted, guiding the sashes to remain truein their relativ 0 positions.

I am aware, as before stated, that locks for meeting-rails have been made having a gravitating bolt pivoted in a casing upon the rail of one sash and bearing against the upper side of the other sash, and having a lever pivoted upon that sash which bears with its on d against the inclined side of the bolt, serving to push the latter in, and I do not wish to claim such construction, broadly; but

I claim 1. In a lock for the meeting-rails of sashes, the combination of a plate secured upon the upper side of the rail of the upper sash, pro- 'ectin be end its inner ed e and rovided- J c y a: P

with wedge-shaped projections upon its upper side, with a plate secured upon the upper side of the rail of the lower sash, projecting beyond the outer edge of the same, and provided with hookshaped lips adaptedto ride upon the wedgeshaped projections of the other plate, as and for the purpose shown and set forth,

2. The combination of the gravitating bolt pivoted in a casing upon the rail of the upper sash and formed with a hook-shaped projection at its lower projecting corner, the b0ltoperating lever pivoted upon the rail of the lower sash, and a catch or lever pivoted below the bolt-operating lever and formed with an upwardly-projeeting hook upon its outer end, adapted to engage the hookshaped projection of the gravitating bolt, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
