SASI-IJ-IOLDER.

Patented Feb. '7, 1911.

Application filed August 27, 1910'. SerialNo. 579,261. v

To all whom it mag "concern:

Be it known that I, JOHAN F. BJ RLUND, a citizen of the United States, and a resident of New York, borough of Queens, county of Queens, and State of New York, have invented certain new and useful Improvements in SashHolders, of which the follow ing is a full, clear, and exact specification.

This invention relates more particularly to a holder or spring adapted for use in conjunction with a window sash for preventing the window from rattling, and is an improvement on my sash holder for which I did obtain a Patent, No. 516,173, dated March 6, 1891. In said former sash holder I employed an elliptic spring formed from a single sheet of metal which is centrally slitted to provide two members having integral opposed ends and are laterally offsetted on different relative planes. When in use one of said'members is seated upon a surface of the frame of the window and the other member is adapted to engage a surface of the stop of the stile of the sash frame. By this formation the strain is directed upon the member bearing against the stop of the window frame in a manner serving to force the other member from its connections with the stile of the sash or the integral ends soon became so weakened as to cause the members to break apart and destroying the usefulness of said spring.

My present invention iscome these objections and has for'its object to provide a sash holder or spring adapted to retain the sash firmly in its frame to prevent rattling when raised or lowered and to accomplish this I provide a form of sash holder comprising mainly three members two members of which are arranged in parallel relation on the same plane. The third member is formed midway 'therebetween, and disposed on a different plane relatively to the first two members so as to receive the bearing direct when the spring is in use and by which the force of pressure is evenly distributed upon the two first members, thus greatly adding to the durability and efliciency of said spring. v i

A further object of the invention is to provide simple and efficient means adapted (01o fasten said members to the sash of a win- A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in designed to ov'erthe said invention being more fully described hereinafter and then pointed out in the appended claim.

In the drawing, Figure 1 is a front view of part of a window frame stilewith my improved-sash holder applied thereto, part of the sash'stop being broken away. Fig.

stop with my sash holder in position when in use, and Fig. 3 is a perspective view of the sash holder. 1 In practice my sash holder 10 is preferably made of a single piece of plate spring metal, or other suitable material, soas to consist ofintegrally formed parts, but it is to be "understood that one or more of .said parts may be separately provided and connected in any suitable manner to the other parts in order to meet required occasions.

When the sash holder '10 is formed of integral parts, as illustrated inthe drawing, two longitudinal incisions or slits 11 and 12 are formedin the material of which said holder is made, and said slits are disposed in parallel relation whereby a middle strip and .two marginal strips or members l3, l4 and 15 are provided. The member 15 is set upward on a different relative plane from the two members 13 and 11in the form of an ellipsis or substantially a diamond shape, as shown inv Figs. 2 and 3 thereby leaving'the ends 16'and '17 intact. As a means whereby said members may be rigidly held to the sash a holding plate 18 having one or more apertures therein for reception of screws or pins, as 19 and'20, Figs. 1 and 2. The members 13 and 15 are formed so that the combined widths thereof will be of approximately the same "width as the stop of the frame of a window.

\Vhen the sash holder 10 is applied to a screws 19 and 20, or the like, to the stile 21 of the window sash, and the members 13 and 14 are directed so as to be seated upon the same surface of said stile. The member 15 will thereby be-posit'ioned so that the central-point ofthe curvature thereof will en gage the opposed surface of the stop 22 of "the window frame 23 so that when the spring is compressed, as shown in Fig. 2, for holding the window in a raised position the member 15 will receive the bearing centrally ATENT oi Fron.

which similar characters of reference indi-' cate correspondmg parts 1n all the views,

2 is a side elevation of the sash stile and t of awindow I provide uponthe member 14;,

window the holding plate 18 is fastened by thereof and from which the force of pres" sure will be distributed through the'integral ends 16 and 17 evenly upon the members or marginal strips 13 and 14. -By this arrangement it is evident that instead of'the forceof of seating said members upon the same surface of'the stileserves to retain the holding plate 18 against displacement, thereby greatly prolonging the durability of my device;

made in the forms and proportion's of the parts of my sash holder, and that the same may be made of any preferred material without departing from the scope and spirit of thein'vention, therefore I do not wish to be limited tothe particular form of sash holder-hereindescribed and shown. 4

1 Having thus 4 described my invention, I

It is to be understoodthat changes may be claim as new am desire to secure by Letters .latent: I 4' n A sash'holder of the character described, comprising a holding plateadapted'to be fastened upon the stile of a window sash, a v member havlng its central part provided upon one part of the holding plate, a second member spaced apart in parallel relation from the first member, and a third member disposed intermediate thereof and having its opposed ends held to the respective opposed ends of the'first and second members, the first and second members being curved and disposed upon the same plane and the third 'member being oppositely curved -so as to form-with the first two members the shape of substantially a diamond. 3

This specification signed and witnessed this twenty sixth day of August AtD. 1910.
