WVILLIAM F. EVANS, OF EVERGREEN, NEW YORK, ASSIGNOR OF ON E-HALF TO JOSEPH H. DEBRAGGA, OF EVERGREEN, NEW YORK.

WlNDOW-SASH HOLDER.

Specification of Letters Patent.

Patented June 12, 1906.

To all whom it may concern:

Be it known that I, WILLIAM F. EVANS, a citizen of the United States, residing at Evergreen, in the county of Queens and State of New York, have invented certain new and useful Improvements in WVindow-Sash Holders, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to windows; and the object thereof is to provide an improved device which will operate to hold a windowsash at any desired point of ad'ustment and which maybe applied either to t e sash or the window-frame; and with this and other objects in view the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable referencecharacters in each of the views, and in which Figure 1 is a sectional side view of a part of a window-frame and a part of a window-sash and showing my improvement applied to the sash and operating in connection with the window-frame; Fig. 2, a similar view showing the improvement applied to the windowframe and operating in connection with the sash, and Fig. 3 a section through the improvement detached and taken on the line 3 3 of Fig. 1.

In the drawings forming part of this specification I have shown at a one side of an ordinary window-frame and at b a part of a window-sash mounted therein, and in the practice of my invention as shown in Fig. 1 I secure in the side of the window-sash a metal casing c, the opposite sides of which are provided with inclined slots or openings 0 and mounted in the casing c and movable transversely thereof or toward and from the window-frame is a yoke-sha ed wheel-holder d, in which is mounted a wheel (P, which is preferably composed of rubber, rubber and canvas, or other similar material, but which may be composed of wood, paperpulp, or any other suitable material, and the shaft d of the wheel d passes through the slots or openings a m the opposite side of the casing c.

The cross-head portion (1 of the yokeshaped holder (1 is preferably extended and made longer than the width of the sides of thewheel-holder d, and placed between the wheel-holder d and the back of the casing c is a curved plate-spring e, which bears on the wheel-holder and one end of which is extended outwardly in the direction of the windowframe to form an arm 6 the end of which is curved inwardly toward the wheel (1 to form a spring awl or finger 6 which bears on said whee and placed in the loop or bend e of the spring-arm e of the spring 6 in the form of construction shown is a transverse pin f.

In the construction shown in Fig. 1' if the sash b be raised the wheel d will turn freely and will not materially interfere with the movement of the sash; but if the sash is moved or moves in the downward direction the spring pawl or finger b will be forced backwardly into the osition shown in dotted lines and the wfieel d will be forced against the frame a and the sash will be held in any position to which it may be adjusted, it being understood that by applying sufficient force to the sash it will continue its downward movement, notwithstanding the back ward position of the spring pawl or finger e In Fig. 2 I have shown my improvement applied to the window-frame, and in this form of construction the casing c is in an inverted position, the spring pawl or finger a being in the bottom portion thereof. With this form of construction the wheel (1 bears on the sash; but the operation and result will be the same as with the location of the parts shown in Fig. 1.

It will be understood that this device may be applied to either the upper or lower portion of the frame, and my invention is not limited to the exact construction or form of the spring e and the parts 6 and e thereof by which the wheel d is forced outwardly, and any suitable spring finger, pawl, or similar device may be substituted for the spring finger or pawl 6 but it being understood that the spring e or one similar thereto must be employed.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A window frame and sash, one of said parts being rovided with a metal casing which is set t ereinto, a yoke-shaped wheelholder mounted in said casing and movable toward and from the other part, a wheel mounted in said yoke-shaped wheel-holder and adapted to bear on said other part, and a curved plate-spring placed vertically in the back of said casing and adapted to force the wheel-holder outwardly, one end of said spring being extended outwardly and formed into an inwardly-directed pawl or finger adapted to bear on the perimeter of said wheel, substantially as shown and described.

2. In a device of the class described, a casing adapted to be set into a window sash or frame, a yoke-shaped wheel-holder mounted in said casing and movable outwardly, a wheel mounted in said yoke-shaped wheelholder, and a curved plate-spring placed vertically in the back of said casing and adapted to force the Wheel-holder outwardly, one end of said spring being directed outwardly and formed into an inwardly-directed spring-pawl adapted to bear on said wheel, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing Witnesses, this 27th day of January, 1905.

WILLIAM F. EVANS.
