SPECIFICATION forming part of Letters Patent No. 456,996, dated August 4, 1891.

Application tiled July 9, 1890. Serial No. 358,166. (No model.)

To all whom, it may concern:

Be it known that I, GODFREY I-I. LASAR, of the city of St. Louis,in the State of Missouri, have invented a certain new and useful Improvement in VVindow-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specilication.

My invention relates to an improved device for holding both the upper and lower sash of a window at any desired elevation, either individually or relatively to each other; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is ahorizontal section taken through the upper sash of a Window on line I I, Fig. III, the lower sash and my improved lock being shown in top view. Fig. II is an elevation. Fig. III is a vertical section taken on line III III, Fig. I. Fig. IV is a section taken on line IV IV, Fig. II, and looking` in the direction of the arrow. Fig. IVe is a perspective view ot' my improved lock, made on a smaller scale than as shown in Figs. I to III, inclusive.

Referring to the drawings, l represents part of the frame of a window, 2 the upper sash, and 3 the lower sash. The frame l is provided with a number of holes or perfor-ations 4 to receive one of the bolts of the lock, and one of the side rails ot the upper sash is provided with a number of pertoraiions or holes 5 to :receive the other bolt of the lock. In the holes may be inserted a bushing 6, such as is shown in Figs. II, III, and IV. l

ll represents a bracket having flanges eX- tending at right angles to each other and which are adapted to tit on the top or meeting rail of the lower sash and to be secured thereto by screws 12 or other suitable means. Formed integral with this bracket are sleeves 13 and 14 and which receive locking-bolts 15 and 1G. The bolt l5 is adapted to fit in the openings 4 to lock the lower sash in any desired position. It is moved in or out to engage or disengage the holes 4 by means of a projecting stem 17, which fits and works in a slot 18 in the sleeve 13. The bolt 16 is adapted to tit in the holes 5, and it is provided with a stem 20, by which it is moved in or out to engage it and disengage it from the holes. It is limited in its movement by a projection 2l, fitting in a slot 22 in the sleeve 14.

My preferred means for holding the bolts in their respecti ve positions is a plate 23, pivoted at 24 to the bracket Il, and which is provided with two recesses 25, one of which is adapted to receive the stem I7 when the bolt 15 is in its outer position and the other of which is adapted to receive the stem 17 when the bolt is in its inner position, the bolt thus being locked in either of its positions. The plate is further provided with a notch 26, adapted to iit over the stem 2O of the bolt 16 and hold the bolt in its inner position, and also adapted to fit over the reduced portion 27 of the bolt 16 to hold the bolt in its outer position. It will thus be seen that the bolt l5 can be held eitherin its closed position or in its open position by the plate 23 regardless of the position of the bolt 16, and vice versa, so that either bolt may be held in its linner or using position whether the other bolt is in using or in non-using position,and thus I am enabled by the use of one lock or bolt and one bracket to hold either of the bolts in either of their respective positions, and consequently am able to lock either sash in any of its positions or to leave either sash unlocked while the other is locked, or to leave them both locked or both unlocked. By a lock thus formed it may be cheaply produced and is strong and durable, being made, so far as the bracket and the sleeves are concerned, of one piece of metal, and so far as all the parts are concerned being so permanently connected together that neither is allowed to be disconnected from the other and the liability ot' loss of any one of the parts is thus avoided.

I claim as my inventionl. In a window-lock, the combination of a bracket, housings formed integral with the bracket, bolts tting in the housings, and a movable plate adapted to engage the bolts to hold them in either position, both in or both out or one in and the other out, substantially as set forth.

2. In a window-lock, the combination of a bracket, housings on the bracket, bolts fitting in the housings, and a pivoted plate having notches adapted to engage the bolts to hold IOO them in either position, both in or both out sash provided for that purpose to more seor one in and the' other out, substantially as cnreiy hold the bracket to the sash, substanset forth. tially as shown.

3. In a. Window-look, the combination of a GODFREY H.' LASAR. 5 bracket having sleeves or housings formed in- In presence oftegral therewith, bolts working in the sleeves, A. M. EBERSOLE,

and one of said sleeves ttingin a hole in the BENJN. A. KNIGHT.
