Description
March 25, 1930. G. A. WILBUR 1,752,218
WINDOW STOP I Filed July 23. 1928 Patented Mar. 25, 1930 UNITED STATES GEORGE A. WILBUR, OF LANSING, MICHIGAN WINDOW strorv Application filed July 23, 1928. Serial No. 294,622.
This invention relates to window stops or sash fasteners, and belongs to that type of such sash holding devices which include a cam or eccentric portion movable into clamping contact with the inside of the window frame, and having means for securing such clamping contact whereby the sash may be raised and held at any height desired. A spring member is also included the function of which is to hold the cam in a yielding manner out of binding contact with the window frame in order that the sash may be moved freely up and down without interference from the fastening devices.
It is an object of this invention to produce a window stop having parts of special construction and arrangement, believed to be very cheap to manufacture and to assemble as required, as well as being applied to the window sash in a very simple manner. It is thought that window stops made in accordance with this invention are very durable, and that they cannot get out of order.-
The special construction and arrangement of the parts of this invention are illustrated in the accompanying drawings, of which Fig. 1 represents an inside view from within a room, showing a portion of a window frame and sash therein with this invention applied 3 thereto.
Fig. 2 is a View of this invention detached from the window frame, showing the curving edge of the cam, with the spring within the casing, and the projecting thumb screw out side of the casing, all the parts being assem bled ready to be placed in the upright of a window sash.
Fig. 8 is a side view of the parts illustrated in Fig. 2, a portion of the casing being broken away to disclose the parts within it.
Throughout the description and drawings the same number is used to refer to the same art.
p Considering the drawings, any desired form of window frame 1, has a sash 2 of any selected size or character movable up and down in the frame 1 in the customary manner. 1
Externally attached upon the upright of the window sash is a plate 3 having a curving slot 4, and through this slot passes a thumb screw 6 having a head 5 by which it may be turned. The head 5 may have a knurled encircling portion 7. i
e The thumbor fastening screw 6 projects as best illustrated in Fig. 2 from the leg portion 8 of alever which comprises also the cam head or end 9. A pivot pin 10 serves as a support for the V-shaped spring 11, and pivotally connects the lever with the casing 12. It will be under'stood'th'atthis casing is to be let into the edge ofthe upright of the window sash, a suitable mortise being cut in the wood to receive the casing.
It will be noted from the foregoing that 6 the parts'are'very few andsimple and that they may be made very strong. It will'also, be observed that the spring 11. engages the pivot on both sides of the cam head of the lever, that it also engages the leg of the lever on both sides, and that it engages the casing on both sides of the lever. This construction and arrangement prevents any dis placement of the cam end or head 9. The operation of this invention is believed to be readily discernible from the drawings and from the description. The spring 11 maintains only a slight rubbing contact between the cam head and window frame when the sash is being raised, but if the sash tends to fall the cam moves into binding contact with the frame. By suitablymoving the leg 8 of the lever, the sash maybe easily raised or lowered, and if it is desired to hold the sash raised at any point, the thumb screw 85 is turned into a clamping contact with the plate 3. The portion of the screw near the head 5 follows the curved slot 4: in the plate, and the leg of the lever is thus moved into any position sought..
Having now described this invention and explained the mode ofv its operation, I claim i 1. In a window stop, the combination with p a window frame, of a window sash movable 95 up and down in the frame, a casing let into the upright of the window sash, a lever pivoted in the casing and comprising a cam portion and a leg portion, the said cam portion adapted to move into binding contact with the said frame, a spring attached to the pivot of the lever and having one portion engaging the leg of thesaid lever and another portion engaging the said casing, the said leg portion of the lever having a fastening thumb screw projecting from the end of said leg portion, and a plate attached to the said upright of the window sash and having a curved slot, the said thumb screw passing through the said slot and being rotatable into clamping contact with the said plate to secure the position of the said cam head against the 'frame.
2. In a window stop, the combination with a window frame, of a window sash movable up and down in the frame, a casing let into the upright of the window sash, a lever pive oted in the casing and comprising a cam portion and a leg portion, the said cam portion adapted to move into binding contact with the said frame, a spring attached to the pivot of the leveron both sides of the lever and having a portion engaging the leg of the-lever on both sides thereof, and portions engaging the said casing on both sides of the said lever,
the said leg portion of the lever having a fastening thumb screw projecting from the end of the-said leg portion, and a plate attached to the said upright of the window sash and having a curved slot, thesaid thumb screw passing through'the said slot and being rotatable into clampingcontact with the said plate to secure theposition of the said cam head against the frame. 7 f In testimony whereof I EtffiX my signature.
GEORG A. WILBUR.
