Application filed May`27,

This invention relatesl to improvements; in latches, and refers more particularly to spring actuated latches adapted to hold the outer ends of a pivotally mounted member, such as a swinging window in line with fa fixed member such as a window frame.

It is an object vof the invention to provide a latch of cheap and simple construction that may be secured to the side of a swinging window sash, and which has an outwardly projecting catch that will cooperate with a slot in a window slide normally provided in the window frame on which the sash swings.

Anotherobject of the invention is to provide a latch which may be utilized on the outer end of a pivotally mounted window sash so that a handle may be employed simultaneously both for releasing the latch and also for swinging the window pivotally into open position.

With these and other objects in View, the invention, which consistsA in certain novel construction and combination of parts, is hereinafter more fully described with the aid of the accompanying drawings, in which* Figure 1 illustrates a perspective viewrof a window frame which slides therein, a window sash pivotally mounted between the slides, and the latch parts on the sash and slides. v f

Figure 2 is a perspective View of part of a sash and portions of the latch prior to assembly, and j v Figure 3 is a plan View of a sash, a slide and a frame, and a latch in engaging position. f

Referring to the drawings, 1 designates an ordinary window frame having usual vertically movable slides 2 therein by which latter an ordinary sash 3 is pivotally supported in a conventional manner.

Pockets 4 are cut in the upper sides of the sash 3 to receive blocks 4 which have forwardly extending vertical flanges 6 adjacent to the inner sides of the said pockets, and the outersides of the blocks also have outward projections 7 along their lower margins. These blocks are held in position as by the inner sides of the holding plates 8 secured to the sides of the sash, and the front margins of these plates are outwardly LATCH.

1927. serial No. 194,568.

upper surfaces of the latter are downwardly and forwardly inclined'and terminatebelow the said pins.

Catches 12bear against the outer surface CORPORATION of the blocks 5, normally rest on the projecs `tions 7, and are pivotally mounted on the pins 11. The engaging members 13 on the rear ends of these catches are outwardlyand when desired also forwardly, flexed, and the outwardly flexedportions which pass through openings 8L1 in the plates '8 are adapted to take into slots 14 cut in the upper surfacesof the slides 2. The operating ends 15 of the catches are inwardly bent toward one another', and have forwardly inclined lower portions 15a. Around the pins 11 springs 16 are arranged one end of which bears against the front surface of its block, and the opposite end of each spring tends to force thelower portion 15a of the operating end of itscatch forward so as to hold the lower margin of the catch 12 down on the projection 7, and its engaging end 13 in engagement with its slot 14.

On the front upper sides of the sash 3 operating handles 17 may be pivotally mounted in bracketsl 18, so that their outer ends rest against the undersides 15a of the operating portions 15 of the catches 12.

t Though when desired these handles may be dispensed with. j v

From the foregoing it will be clearly seen that when the inner ends of the handles 17 are pulled forward'the engaging ends 13 of thev catches are. raised out of engagement from the slots 14. Or again, as the sash is moved into vertical position the undersides and flexed subStantially at right angles thereto to engage said slot, an operating end on said catch also flexed substantially at right angles to said catch and having its lower portion forwardly inclined,A and a spring around said pin having one end in Contact With said block and its opposite end in contact with the lower portion of said operating end, said Ilower portion being normally pressed' `forward by said Spring thereby tending to hold said engaging end in said slot.
