Description

2,723,144 Patented Nov.v 8, `1955 ited States Patent ilice 2,723,144 CAM LEVER WINDOW. SASH TIGHTENER Joseph E. Haynes, Baltimore, Md.
Application January 22, 1951, Serial No. 207,179 3 Claims. (ci. 292-75) This invention relates to the windows of the vertical reciprocating type where the sashes are replaceable, at the option of the user.
The invention has amongst its objects to provide a new and improved window sash that can be readily installed and removed without detaching any portions ot the window frame to do so.
Another object of the invention is to provide a new and improved sash holding device that can be installed in the sash and operate in the window frame to hold them operably together.
A further object of this invention is to provide a new and improved sash holding device that will be simple in construction, easy to manipulate and eifective in operation.
A further object of this invention is to provide a new and improved sash tensioning device that may be locked in either extended or retracted positions.
Other objects of the invention will be apparent as the invention is more fully set forth.
For a better understanding of the invention, and its principles and operation, reference is made to the accompanying drawings, which disclose a particular form of the invention by way of example and not of limitation. These drawings are explained in the following description while the claims indicate the scope of the invention.
Referring to the drawings:
Figure l is a front elevation of a window and sash structure employing a sash holding device embodying this invention;
Figure 2 is an enlarged plan View of the device;
Figure 3 is a sectional elevation of the device taken along line 3 3 of Figure 2, and shown in extended position;
Figure 4 is a view similar to that shown in Figure 3 with the device in retracted position;
Figure 5 is a sectional plan view on line 5 5 of Figure l;
Figure 6 is a sectional plan view on line 6 6 of Figure 1;
Figure 7 is a detail of a tool used for operating the device;
Figure 8 is an end View of Figure 7 showing its socket key, and
Figure 9 is a sectional view on line 9 9 of Figure 4, indicating the cam mechanism.
Similar reference numerals refer to similar parts in all of the drawings.
In the construction shown in the drawings, a sash holding device comprises a rectangular block or housing 10 including a rectangular chamber 11 throughout the greatest part of its length. The block or housing is preferably provided with a side cover 12 secured to its side by screws driven into the holes 13. The purpose of this cover 12 iS to enable access to be made to the interior as well as to hold the parts in appropriate alignment. The components of the block or housing include a triangular sliding element 14, with its head 15 having its upper surface 16 relatively flat and straight while its under surfaces- 17 taper from the middle towards' the ends ofthe element 14. The stem 18 of the element 14 is made short and is provided witha pin 19 extending transversely through it.- This pin 19 supports the long arm 22 of a lever 20 that actuates the sliding element 14. The levers fulcrumed onl another pin 21 installed in the block 10 and passing through the chamber 11. The shortl arm 23 extends towards the end wall of the chamber 11 as indicated.
The short arm 23 vof the lever 20 has a circular slot 24 in which: a cam member 25 revolves to tilt the lever 20 and raise or lower the sliding element 14 through a shortarcuatepath and to holdl it inrthat position. The hat bent spring 26 facilitates this actionby reason of its form andthe fac-t that it is looped at the front end at 2-7 on a pin `28v transversely disposed in the block or`housing 10. The opposite-end portion of the spring 26 is left free s'o that it can slide 'under the cam member 2'5 as it is straightened out under the action of the element,.14. See Figures 3 and 4. The element 14 is providedvwith a roller 29 at one side thereof that serves to make its head 15 slide easily in a channel 31 of the window frame 30, in which it rides. The roller 29 also presses on the spring 26 to make use of its resiliency, in conjunction with the pressure exerted by the stem 18. When the sliding element is collapsed it brings its head 15 flush with the upper face 39 of the block or housing 10.
The cam member 25 consists of a pin 32 mounted on the inner face of the block by a screw 46 and it supports a cam shell 33. The middle portion of the face of the cam shell rides against the short arm of the lever 20 tilting it about pin 21 and raising the element 14 and lowering it intermittently as the shell is revolved to a point where the undercut 43 contacts the arm 23. The shell is contoured and diametrically slotted at 34 to enable a tool head 35 to be used therein, to turn it. The details of the tool arey indicated in Figures 7 and 8 and include a bent shank 36 to facilitate operation.
The vertical sides 41 of a sash 40 are recessed at suitable loci 42 for the device so it can fit neatly therein and set ilush. The head 15 is arranged to enter the channel 31 on the frame 30 and slide along it when in extended position, as shown in Figure 3, and set flush when in collapsed position, as in Figure 4. If preferred the sash may have rollers 37 installed on the side thereof opposite that carrying the fastening device to reduce frictional resistance.
A wing 38 of resilient material is also used adjacent the roller 37 to make the sash non-chattering where it enters in the channel 31 of the frame.
The device is readily collapsed when the sash 40 with its glass 47, is to be inserted or removed from the frame. After it is aligned with the channel in the frame,
the sliding elements 14 are released by turning the cams so that their heads 15 will press against the frame resiliently and hold the sash against lateral removal from the frame. lowered freely. The collapsing of the device enables the sash to be removed from the channel of the frame. The insertion and removal, require a slight tilting of the sash to facilitate these purposes. The cam and lever mechanisms are so arranged that they will hold the componentsk securely until the tool 35 or a coin is employed to release them from the one position to the other. This is a protection against unauthorized tampering with the sash or its removal from its framework.
While but one general form of the invention has been illustrated herein, it s not desired to limit this application for patent to such particular form as it is appreciated that other forms could be designed and made that would employ the same principles and come within the scope of the appended claims.
The device allows the sash to be raised and Having thus described the invention, what is claimed is:
1. A fastening device for locking a window frame and a window sash comprising a hollow block adapted to be secured to the sash, 'a sliding element movable in and out of the block, said element having a at face and a roller at one end protruding slightly beyond said face, said roller and rnost of said face contacting the frame when the element is in extended position, means for moving said element in and out of -the block, said means comprising a lever pivoted between its ends to the block, pivotal means between one end of said lever and the sliding element, a cam Within the block cooperating with the portion of the lever comprised between its free end and its pivot to the block to tilt the lever in a direction to retract the sliding element and house it within the hollow block, and `a flat spring secured at one end to the block and urging the sliding element in its extended position, `the opposite end of the spring being wedged between the cam and the hollow block.
2. A fastening device as set forth in claim 1 wherein the flat spring is` in constant contact with the lever at the point where the said lever is pivoted to the sliding element.
3. A fastening device as set forth in claim l, wherein the cam is provided with diametrical slots along one of its faces whereby it may be engaged and actuated by a suitable tool.
