SASH LATCH Filed Aug. 51, 1927 Mmc MMM

Patented Aug. 13,1929.

UNITED STATES ROY H. BERGSTROM, 0F LOS ANGELES, CALIFORNIA.

SASH LATCH.

Application filed August 31, 1927. Serial No.` 216,577.

This invention relates to improvements in sash latches.

An object of the invention is to provide an improved sash latch which is adapted to be mounted upon one of two sash movable relatively to each other, which will serve to rlimit the relative movement between the sash so that they can not be opened from the outside.

Another object of the invention is to provide a sash latch for the above mentioned purpose which will take care of itself so that it is normally in that position which will limit the relative movementbetween the sash so thatv it; is not necessary to manipulate any part in order to hold the sash against relative movement. The improved sash latch however, can be moved into such position from the inside as to perm'itthe relative movement of the sash.

A further object ofthe. invention isy to provide an improved sash latch which is self-actuated on moving the sash from open position to closed position. f

Another object of the invention is to pro`- vide a sash latch of novel, simple and durable construction.

With the foregoing and other objects in view, which` will be made manifest in the following detailed description vand specilically pointed'- out in the appended claims,A

reference is had to 'the accompanying draw.- ings for an: illustrative embodiment of the invention, wherein: i

Figure 1 is a partial view in perspective of two sash, illustrating the improved sash latch as having been mounted thereon. Fig. 2 is a vertical section.v taken substantially upon; the line 2-2 upon Figure l, illustrating the sash in ful-ly closed position before the sash latch has become operative.

Fig.v 3 is a view similar toFigure2, illustrating the manner` in which the latch limits the relative movement between'the sash.'

Referring to the accompanying drawing `wherein similar reference characters designate similar parts throughout, the frame of the window is indicated at F, in which there are two sash, S and S. Tlhese window sash are vertically slid-able in the window frame and the;y sash S is shown as havin-g a stile 10 and a bottom rail 11,'while the lower sash S has a top rail- 12 and a stile 13. The sash latch consists of an open sided housing 1&1 which is adapted to be recessed in the stile 10 of the upper sash. This housing is somewhat deeper at the bottom than at the top and has an apertured flange 15 about its open side to receive screws 16 by which it may be attached to the stile 10. A pin 17 extends transversely across the housing and serves to pivotally mount a latch member 18 which has a s-lot 19 through whichl the pin extends. The latch member, whenv in the position .shown in Figure 2, presents an outwardly and downwardly inclinedA outer surface 20, a rounded bottom surface 21 and a shoulder 22 on its inner surface which, when the vlatchV member ismoved into the position shown in Figure 3, forms a horizons tal abutment. vThe formation of the latch member is such that it normally pro-jects a short distance throughv the open side of the housing due to gravity. To insure the latch member assuming suchnormal position, a

. small leaf spring 23 is fastened tothe back of the housing `and is engageablewith the latch member to keep it in this position.

' The back and top walls of the housing are so positioned that when `the latch member is swung into the upper position, the edge 24e will bear against the back and top walls of the housing so as to limit the movement ofthe latch member int-wo directions when the latchY member is in its upper or locking. position. Such bearing engagement between the 'edge 24' and the back and top walls is permitted by the pin and slot connection at 17 and'19;

Y rEhe operation of the improved sash lock is as follows:

` The'latch member being in the position shown in Figures 1 and 2, if either ofi the sash. should be started from the closed position to the open position, the latch. inem .ber will have its bottom surfaces 21 engage the top surface-ofthe rail 12 onthe lower sash S. A further movement causes theA latch member 18 to swing upwardly from the position shown in Figure 2y to the dotted line position shown on this figure or the full line position shown in .Figurel In suchpositionthe shoulder 22 forms' theA hor'izontal abutment which is adapted to be engaged by the topY surface of the rai-1l 12,

limiting the relative movement betweenthe sash. In such position any force imparted to either of the sash to force the sashf open will` be transmitted by the latch member to the back and top walls of` the housing, 14

so that all-strain on the pin 17 is eliminated.

If it is desired to open the sash, this can be accomplished by forcing the latch member inwardly againsty the action of the spring 23 so that the latch member will be entirely contained within the housing. Vhile in such position the lower sash S can be started upwardly or the upper sash S can be started downwardly, and after the edge l24. has passed beneath the top surface of the rail 12, the latch member will be kept within the housing by its engagement with the outer side of the stile 13. When the sash are subsequently moved into closed position, the latch member y18 is caused to swing outwardly into the position shown in Figure 2. If desired, a protecting plate 25 may befastened over the top surface of the rai1'12 and down over the outer surface of the stile 18 to prevent the latch member `from marring or scratching the lower sash. From the above described construction it willbe appreciated that it is not necessary to manipulate the latch in order to have it hold the sash against material relative movement.` Whenever the sash are moved into their closed positions, the latch acts automatically to move into locking posit-ion.

' The improved sash latch is not limited in of the invention use to the exact position shown. If the window has merely the lower sash slidable, the sash latch can be mounted either upon the upper stile 10 or on the window frame F so as to engage the top rail 12 of the lower sash S in a manner similar to that as above described. It will thusbe seen that a novel, simple, durable and advantageous sash latch is provided which can be easily and quickly installed, and which may have an attractive appearance. Y l

This sash latch is, especially intended for permitting the lower or upper sash to be raised or lowered respectively for ventilation and yet preventing t-he unauthorized furtherV opening of the sash from-the outside,thusv being in a sense a burglar proof device. y Y It will be understood that various changes inthe details of construction may be made Vwithout departing from the spirit or scope as defined by the appended claims. I

I claim: Y Y
