WILLIAM D. FOSS, OF BELL, CALIFORNIA.

SASH HOLDER.

Application filed October 9, 1924. Serial No. 742,693.

To all 'whom t may camera:

Be it known that I, WILLIAM D. Foss, a citizen of the United States, residing at Bell, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sash Holders, of

i which the following is a specification, reference being had to the accompanying drawinvs.

E3This invention relates to window constructions, particularly to sashes, and has for its object the provision of means associated with a sash and co-operating with the` window frame'or casing whereby to avoid theuse of the well known weights. i

An important and more specific object is the provision of friction devices held under spring tension and permanently carried4 by the sash and' Gol-Operating with the window stile for the purpose of positively holding the sash atany desired adjusted position.

Another object is the'provision of holding -means of this character in which the springr tension is adjustable so as'fto enable the device to be used satisfactorily and successfully in connection with window sashes of diiferent weights7 it being obvious that a large sash will require greater tension than a smaller one. w f

A further object is' the provision of sash 'holding means of this VCharacter which Will be simple and inexpensive in manufacture, easy to install, positive in action, convenient 'in use, efficient and durable in service, Aand a general improvement in the art.

' With the above and other objects and advantages in view, the invention consists in the details of construction toV be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which: f i

Figure 1 is an elevation of awindow showing a pair of sashes therein, parts of the sash rails being broken away to disolose thelocation of the holding means; i i

Figure 2 is a fragmentary edgevelevation of one sash showing one of the holding mem- Figure 3 is an enlarged longitudinal sec- -tionthrough a fragment of'the sashrail and .the Cleviel o Referring more'v particularly to the drawings, the letter A designates the side of a window frame or casing, and B represents a pair of sashes slidably mounted therein vin the usual manner. Ordinarily a window is provided with weights having cords or chains attached thereto,,trained over suitable guide pulleys or rollers and connected with the'sashes for counterbalancing the' sash so that it may be easily moved from one position to another and so that it will remain' in any desired position. that the sashcords or Chains break whereupon the weights dropl down within the windoW oasing and become useless so thatthere is then nothing to hold the sash. Another disadvantage in the ordinary construction is that the sashes may rattle especially during wind storms and may vibrate and make an objectionable lnoise especiallyV -in cities or other places where there is considerable traffic which naturally produces a j arring effect.

To overcome the above well recognized disadvantages, I have designed the present invention which' entirely eliminates the use of the well; known weights. In carrying out the invention I equip each sash with a vdesired number' of'friction devices whichcooperate with the sides of the window frame or 'casing for holding the sashes in any .flesired position. Each .friction device is formed as an elongated angular strip 10 of resilient metal,` preferably spring steel, which strip is mountedwithin an elongated recess 11 in the' edge of thesash rail. One end of the recess is deepened at 12 for accommodation of the voffset or angular end 13`of thev strip and this deepened portion leads into a socket 14 containing a met-allic bushing 15 vwithin 'which is located a coil spring 16 bearing against the offset or angu- Alar end of the strip 10;

` Secured upon the angular end'l of the strip 'sa suitable bracket or. yoke 17, here disclosed as `of' U-shape, riveted, brazed, or otherwise mounted `and having journaledV therein on a -pintle or pin 18 a roller 19of metal, fiber, or any other desired or suitable material,which roller is designedf'to bear against the adjacent side 'of the' window frame -orcasing It o frequently occurs The strip is held in place within this groove or recess 11 by means of screws and 21, the former of which is intended to be left permanently in place and the latter 5 of which is capable of being scrcwed in to a greater or less extent whereby to vary the spring tension on the device. It will be observed that the recess 11 is slightly tapered so that by turning the screw 21 in, the strip 10 will be drawn into the recess 11 to a greater extent, thereby moving the roller 19 slightly into the socket 14. In other words this second named screw 21 may be considered as a stop for limiting the outward mover ment of the strip and consequently the roller under the influence of the spring 16 and also under the influence of the natural resiliencc of the strip itself. This feature is of great importance as such adj ustment may be necessary to take care of variat-ions in the fits of sashes as it is obvious that in case of a loose fitting sash the roller would need to project outwardly beyond the sash to a greater eX- tent than in the case of a more closely fitting sash. Furthermore, this feature enables the device to be used successfully with sashes of different weights, it being obvious that the spring tension need not be as great for a light sash as for a heavy or large one.

In the use of the device it is evident that when the sash is raised and lowered in the customary manner and that whenever it is left at a desired point, the spring tcnsion applied to the strip 10 and consequently the 35- roller will insure suiiicient frictional resistance to maintain the sash in the desired position so that it cannot casually slip down. Furthermore, the deviceiwill act to take up any looseness between the sash and the window frame or casing so that rattling or vi- 'bration from wind or any other cause will be positively eliminated.

i From the foregoing description, and a Study of the drawings, it will be apparent that I have thus provide-d a simply constructech inexpensive and easily applied means for the purpose specified which Will etiiciently perform all of the functions for which it is intended. Owing to the simplicity and fewness of part-s, together with the rnggedness of the' construction it is obvious that there is practically nothing to get out of order so that the device should have a long and satisfactory life.

Vhile I have shown and described a preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as Will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described the inv'ention, I claim.:

L The combination with a window casing .and a sash mounted therein, the side face of Lat/'0,885

the sash being longitudinally recessed and the sash at one end of said recess being formed with a socket, of a resilient strip disposed in the recess and extending longitudinally thercalong, one end of the strip being inwardly off-set with respect to the sash and carrying a roller adapted to engage the window casing, av spring disposed in said socket and engaging the inwardly off-set end of the strip and urging this end of the strip and the roller outward, the end of the strip opposite said off-set portion resting flat against the bottom of said recess and being attached to the sash frame, the recess between said point of attachment of the strip and the off-set portion thereof having its bottom re-entrantly inclined, and a screw passing through the strip opposite the deepest portion of this last named part of the recess and engaging the window sash whereby the strip may be shifted inward against the action of said spring or may be permittcd to shift outward under the action of the spring.

2. The combination with a window casing andV a sash mounted therein, the sash being provided with a socket extending inward from the edge face of the window casing and with a recess extending longitudinally toward said socket, that portion of the recess adjacent the socket being inclined inward and intersecting the socket midway of its depth, a longitudinally cxtending strip mounted within the recess and extending into the socket and carrying a casing engaging roller, that portion of the strip disposed within the'oif-set portion of the recess being angularly bent inward and the recess for the greater p'ortion of its length being deeper than the thickness of the strip, a coiled compression spring disposed within the socket and bearing against the end of the resilient strip and urging said end-outward, fastening means at the other end of the strip, and a'n adjusting screw engaging thetrip and window sash between the fastening means and the socket whereby the strip may be adjusted inwa-rd against the action of said coiled spring or Vperm'itted to move outward under the actionof lthe sprind,

3, The combination with a window casing and a'sash mounted therein, the edge of the sash facing the'window casing having an in- Wardly extending socket and the edge of the `sash'being formed'with a' longitudinally extached to the window sash at'one end and'at the other end extending threugh the slot in the sleeve and carrying a ,rofiller coiled compression spring disposed Within said sleeve and bearlng agalnst the free end of the strip, the strip being bent inward into the inwardly extended portion of the recess and the recess between said inwardly extended portion and the point of attaehment of the strip being greater in depth than the strip, and a screw passing through this portion of the strip and into the sash Whereby the strip may be shifted inward against the 10 force of said spring or permitted to move outward under the action of the spring.

In testimony Whereof I hereunto affix my signature.
