PATET OFFI E GEORGE D. SHINN, OF RUSSELLVILLE,IABKANSAS AUTOMATIC wmnow LOCK Application filed July 10,
' vention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Fig. 1, is a perspective view of a window sash and frame with my invention attached thereto,
Fig. 2, is a perspective view of the latch member,
Fig. 3, is a perspective view of one form of catch, and,
Fig. 4, is a perspective View of another form of catch.
In the drawings, wherein for the purpose of illustration, I have shown a preferred embodimentof my invention, the numeral 5, de-
notes a conventional type of window frame, having upper and lower sashes 6 and 7 slidably mounted therein.
My improved lock consists of latch members 8 carried by the sashes and adapted to engage catches 9 and 10 attached to the window frame, whereby the sashes are locked or maintained in various positions. The latch members are formed from a single piece of wire or other suitable material having a loop 11 formed intermediate its ends for reception of a screw 12 by means of which the latch member is pivotally attached to the face of the sash adjacent the inner face 13 of the window frame. Both ends of the latch member are bent at right angles as at 14, and the upper arm 15 is slightly longer than the lower 192s. Serial No. 291,592.
The catches 9 and 10 consist of a plate 17 provided with openings 18 to receive screws 19. for fastening the catches tothe inner face of'the window frame in the path of travel of the latch members. The plate 17 is provided with a side flange 20 extending at right angles thereto, the flange of the catch 9 having its outer edge inclined downwardly and inwardly, as at 21, towards the inner face of the window frame.
Theflange of the catch 10 has its outer edge inclined downwardly and outwardly from the inner face of the window frame, as at 99 and ad acent its lower end is provided with a notch 23, fora purpose to be set forth more fully hereinafter. V
In use, a catch 9 is secured to the window frame adjacent the top and in closing the upper sash, the upper arm of the latch member will run up the inclined edge of the flange .20 and automatically engage over the top edge of the flange, thereby locking the window sash. To open theupper sash the lower arm of the latch member is swung inwardly,
moving the upper arm from engagement with the catch. To control the operation of the lower sash, a catch 9 is attached to the window frame adjacent the upper sill of the lower sash and the catch 10 is attached to frame between the catch 9 and the window sill. WVhen the lower sash is closed the upperarm of the latch member is engaged with the bottom edge ofthe flange '20 of the catch 10, locking the window against opening. To raise the sash the latch member is moved from engagement with the catch 10 and when the sash is fully opened it engages the catch 9, locking the window sash in its open position. When it is'desired to only partiallyraise the lower sash, the lower arm of the latch memberis manually moved into engagement with the notch. 23 in the flange of the catch 10, the weight of the sash holding it t in the notch until removed.
It is to be understood that the form of my invention herewith shown and described is i to be taken as a preferred example of the size and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim 1. A window sashlock comprising catches attached to the window frame each consisting of a plate having a vertical flange extending at right angles thereto, the outermost edge of said flange being inclined towards the window frame, and a pivoted latch member attached to the sash having angularly bent ends adapted to automatically engage over the flanges of the catches.
2. A window sash lock comprising catches attached to the window frame each consisting of a plate having a vertical flange ex-v tending at right angles thereto, the outermost edge of said flange being inclined towards the window frame, and a pivoted latch member attached to the sash having one end over-balanced and provided with an angular extension adapted to normally contact with the window frame, whereby it automatically engagesover the flanges of said catches.
3. A window sash lock comprising catches attached to the side of the window frame consisting of a plate having a vertical flange extending at right angles thereto, the outermost edge of said flange being inclined towards V the window frame, and a latch member consisting of a wire rod pivotally mounted intermediate its ends to the sash, the ends of said rod being'bent at right angles, one end being over-balanced whereby 'it normally contacts with the window frame, automatically engaging over the flange of said catches upon raising and lowering of the sash- 4. A window sash lock comprising upper and lower catches attached to the window frame, each consisting of a plate having a vertical flange extending at right angles thereto, the outermost edge of said flange being inclined towards the window frame, said lower catch having a notch'formed in its inclined edge, and a latch member pivoted intermediate its ends to the sash having angularly bent ends, one end being over-bah anced whereby it normally contacts with the window frame, automatically engaging over the flanges of saidcatches upon raising and lowering of the sash, the opposite end of the latch being movable to engage the notch formed in the inclined edge of the lower catch to support the sash in a partially raised position. 7 7
In testimony whereof I aflix my signature.
GEORGE D. SHINN.
