CONTROL DEVICE FOR SLIDING MEMBERS Filed Jan. 2, 1955 30\\ HH sa'o 38/ 5 a4 IN V EN TOR.
United States Patent CONTROL DEVICE FOR SLIDING MEMBERS James S. Coppola, Lynn, Mass.
Application January 2, 1953, Serial No. 329,352
2 Claims. (Cl. 292-78) This invention relates to a device to control the movement of sliding members such as window sashes.
One object of this invention is to control the sliding of a window sash in the window jamb without the use of weights or other complicated control apparatus.
Another object is to provide such a control device that is compact, is carried by the window sash as it moves, and is adapted for use with old or new windows.
A further object is to provide stop means, conveniently located, whereby the friction between the window sash and jamb or riding rail can be varied as desired.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore I am not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims.
In the drawings:
Figure 1 is a fragmentary, front elevational view of window apparatus showing my device mounted in the window sash.
Figure 2 is a sectional view taken on the line 22 of Figure 1.
Figure 3 is a sectional view taken on the line 33 of Figure 1.
Figure 4 is a perspective view of the pressure member used in my device.
Figure 5 is a perspective View of the spring member used in my device.
Figure 6 is a side elevational view of said pressure member.
As illustrated, my device has a frame or supporting member 10 having two sides 12 and 14, a top 16, a bottom 18 and a front 20, the latter having a threaded hole 22 therein. Each said side has a hole 24 therein. A pressure member 26 has a hole 28, preferably eccentrically located, extending laterally therethrough, and a shaft 30 extends through it and is set in said side holes 24, the pressure member 26 being rotatably movable on said shaft 30. There is a washer 31 on said shaft 30 at one side. A spring member 32 bears against said supporting member front 20 at one end, as at 34, encircles said shaft 30, preferably twice, at the side opposite said washer 31, and bears against said pressure member 26, terminating in an angle portion 36 that extends over and bears against a side of said pressure member 26. Its use is desirable to yieldingly maintain said pressure member 26 in any predetermined position chosen.
The pressure member 26 has a contact surface 38, a portion of which is arcuate and eccentric to the hole 28 with the longest radius from the hole to the contact surface, as shown, at the lower end. At the opposite side thereof, it has a shoulder 40, against which an adjustable stop member 42 normally bears or is adjacent thereto.
This stop member 42 is shown in the form of a screw that extends into a countersunk hole 44 commencing at the front of a window sash S, and screw-threadedly counects with said screw-threaded hole 22 in said front 20.
In use, I preferably provide a riding rail, made of metal or other durable material that lies fiat against the window jamb J, and may be held in place there by a nail or screw. This rail has a flange portion 46 that is set against the parting bead B or slightly projects thereinto, while extending at a right angle therefrom is a rail contact portion 48 that extends away from said jamb J. The window sash S, at the inner side thereof, is shown with a kerf K cut therein from top to bottom intermediate the front and rear surfaces, and said rail contact portion 48 extends into it with said pressure member contact surface 38 normally contacting and sliding on said portion 48. This riding rail also serves as a weather strip.
Said pressure member 26 is so positioned that when the window sash S is raised, the relatively higher or projecting point of its said contact surface 38 is moved away from or into lighter contact with said rail contact portion 48, or the window jamb I if said portion 48 is not used. Also said contact portion is then spaced from said stop member 42. When the sash S is moved lower, a relatively high point of said contact surface 38 is moved into contact with said portion 48 thus increasing the friction between said pressure member 26 and said rail contact portion 48 which offsets the inclination of the sash S to slide downwardly faster than desirable. This downward movement causes said pressure member shoulder 40 to move into contact with said stop member 42, hence the pressure member 26 remains in a predetermined position, that it moved to, during this downward movement.
Ordinarily two of my devices are used in each window sash S. Each is installed by making an opening 50 in the side of a window sash, cutting from the outer edge inwardly to provide sufficient space to receive said supporting member 10. Said stop member 42 is inserted in said window sash hole 44, and screw-threadedly connected with said supporting member hole 22, and moved into contact with said pressure member shoulder 40. The farther said stop member 42 extends into said window sash S, the less friction there is between the sash S and said rail contact portion 48 because movement of said pressure member 26 keeps a lower or shallower portion of said contact surface 38 against said rail contact portion 48. When said stop member 42 is loosened by screwing it outwardly, said pressure member 26 can rotate towards a position where a higher point of its contact surface 38 contacts said rail portion 48, hence the friction there is increased, and said stop member 42 keeps said pressure member 26 from passing beyond this point.
Another use for my device 10 calls for only one to a window sash S, in which event the device would be set in a position in said sash opening 50 at a right angle to that shown in the drawing. In this arrangement said pressure member contact surface 38 will bear directly against the window jamb I, and said stop member 42 would extend from the inner side of said sash S against said shoulder 40, instead of extending inwardly from the front as shown.
What I claim is:
1. A control device for a sliding window comprising a supporting member having two sides and a front for insertion into an opening in a window sash, said front having a hole therethrough, a shaft mounted on and supported by said supporting member sides, a pressure member rotatably mounted on said shaft having an exterior contacting surface and having a shoulder portion commencing at an end extremity of said contacting surface and extending therefrom in a general direction towards, and reaching a point adjacent said shaft, said hole being appreci ably lower than the upper extremity of said shoulder portion, and a stop member adapted to extend into an opening in said window sash and passing horizontally through said hole, movablysupported by said supporting member front and adapted to contact said shoulder portion. r V g 2. A Control device fora sliding window comprising a supporting member having two sides and a front; for insertion into an opening in a window sash, said front having a hole therethrough, a shaft mounted on and supported by said supporting member sides, a pressure mem ber rotatably mounted on said shaft having an exterior eont aeting surface andhaving a shoulder portion commencing at an end extremity of said contacting surface and extending therefrom in a general direction towards shaft, and a stop member adapted to extend into an opening in said window sash and passing horizontally through said hole, movably supported by said supporting member front and adapted to eontact said shoulder portion, said stop member extending normal to the vertical axis of said supporting member front in position of use.
