WEIGHTLESS WINDOW SASH Filed Aug. 28, 1952 fomuno W Ska/"k2 INVENTOR.
United States Patent WEIGHTLESS WINDOW SASH Edmund W. Skarke, Tulsa, Okla.
Application August 28, 1952, Serial No. 306,770
1 Claim. (Cl. -52.6)
The invention relates to weightless window sashes, and has for its object to provide a device of this kind wherein the sash is held in various open positions by means of cooperating strips carried by one side, or both sides of the sash, and having engaging cam surfaces adapted to bind against the inner sides of the various stops and the parting stop for holding the sash in adjusted position.
A further object is to provide a sash holder comprising a stationary strip carried by one side of the sash and engaging one side of the parting strip, and a longitudinally movable strip having a floating connection to the side of the sash, said strips having cooperating bevelled cammhig surfaces forming means whereby the sash may be easily adjusted when the floating strip is moved in one direction and rigidly held against movement when the floating strip is released so that both strips frictionally engage the adjacent surfaces of the parting strip or stop, and the inside stop or outside stop.
A further object is to provide spring means for longitudinally moving the floating strip to holding position when released.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawing:
Figure 1 is a side elevation of a pair of sash showing the window frame in vertical transverse sectional view, and the various stops in elevation.
Figure 2 is a detail perspective view, partly in section and broken away, taken on line 2-2 of Figure 3.
Figure 3 is a horizontal sectional view taken on line 33 of Figure 1.
Referring to the drawing, the numeral 1 designates a conventional form of window frame, 2 the still. The window frame is provided with conventional inside stops 3, parting stops 4, and outside stops 5. The sash holding means hereinafter set forth is designed to hold the sash in various adjusted positions, and to obviate the use of weights.
The sash holding means is duplicated on the sides of the upper and lower sash, however they are alike, consequently one will be described, and the numerals will apply to all the parts.
Secured by means of screws 6 to the sides of the sash 7 is a stationary wedge strip 8. The strip 8 is provided with a plurality of wedges 9, which, in the case of the lower sash, inclines downwardly and inwardly, clearly shown in Figure 2.
Secured to the side of the sash at its upper end is a back-up block 10. A floating or movable wedge strip 11 is disposed in side engagement with the side of the sash 7, and provided with a plurality of wedges 12 cooperating with the wedges 9 on the strip 8. It will be 2,715,248 Patented Aug. 16, 1955 ice noted that when the operator forces the finger engaging member 13, carried by the movable strip 11, upwardly towards the stationary finger engaging member 14 carried by the sash 7, the floating strip 11 will move vertically and laterally inwardly, therefore it will move out of binding engagement with the inner side of the inner stop 3, thereby allowing the sash to move easily upwardly or downwardly, as desired. Interposed between the end of the movable wedge strip 11 and the block 10 is an expansion spring 15. Expansion spring 15 moves the strip 11 downwardly when the finger engaging member 13 is released, and the wedges 12 and 9 will cause the strip 11 to move laterally into binding engagement with the inner stop and the stationary strip 8 into binding engagement with the parting stop. It will be seen that the sash will be rigidly held in any adjusted position. It will also be seen that the sash can not be elevated until the movable wedge strip 11 is moved to inoperative position.
The upper sash 7a is controlled in the same manner as the lower sash 7, the parts being, preferably, reversed as shown, so that the finger engaging members 13 and 14 will be at the top of the sash. It will also be seen that with the wedge holding any attempt to jimmy the window the wedging action will be increased with the amount of force applied.
From the above it will be seen that a sash holding device is provided which is simple in construction, may be easily and quickly applied to sash now in use, and one wherein a wedging action is used for holding the sash in various adjusted positions without the use of weights, and the use of a sash lock is obviated.
The invention having been set forth what is claimed as new and useful is:
The combination with the side of a window frame having spaced apart inner and outer stops and with the side of a sash slidably mounted between the stops, of means for holding the sash in adjusted positions between the stops, said means including a block mounted transversely on the side of the sash, coplanar side by side complementary strips carried by the side of the sash and each having one of their ends disposed adjacent the block, one of the strips being fixed to the side of the sash and the other being movable axially and laterally on the side, said strips w having confronting faces provided with engaging wedge portions which, in one axial direction of movement of the movable strip, bind the strips against the stops and, in the opposite axial direction of movement of the movable strip, permit the movable strip to move laterally toward the fixed strip, said movable strip having an axial bore in the end adjacent the block, an expansion spring seated in said bore and engaging the block to bias the movable strip away from the block in the axial direction of engagement of the wedge portions to force the movable strip laterally from the fixed strip', a finger engaging member extending outwardly from the sash at right angles to the side of the sash and a second finger engaging member carried by the movable strip and projecting from the face of the strip opposite to the face provided with the wedge portions, said finger engaging members being in opposed relation so that when the finger engaging members are gripped and the second member moved relative to the first member, the movable strip is moved axially in opposition to the spring and is permitted by the wedge portions to move laterally toward the fixed strip and out of binding engagement with one of the stops.
