To fr/Z fr/mm il 11H15/ wnww'n:

Be it knmvn that L ALM .n M. Lima, a Citizen nt' the United States, and a res-ident il the city of St.y Lmiii and State if Mii-r Sinni, have invented a new nnel useful inn prmfniint in Tv'inilow-Adjusters, 01" which the 't'nlhiwing' is a ipeuiiiativn l`li-1 iziwntirin relates puri' -larlv in seif-ailinetiiigf rolls nr propr tm' holding wringing: iviiitlnw in pm or partly wpen pfeitiwn.

in thix iiim'liiill forme; nf uimrftriwtimi shown in Figs. l anti the inner member 23 i a inlw. and at its inner enel it has two uppnsitllv Jispuswl iivlus 2i thi'fiifli .its ivaii in ivhii'h the friftiwn Show 11; are arraiigmlA ln the torni shown in Fig. 4, the friction frhies are presser] apart against: Athe: will# ni" the unter tubular member 12 by a pair nf flat springs QG which have their inner @nih firinlv held, in :i slut in a block if, The hiirrk .27 is held in the tubular memlwr il 'by means of a pm whifh aim holds the eprings 26 in the sinn In the onstruc tion shown in Fig. 5, a single U-shlpe spring 29 is arranged in the inner tube 23, with its ends between the friction shoes 25, and pressing the friction shoes 25 against the walls of the outer tubular member 12. The spring 29 is secured in place by a transverse pin 30 passing through the closed end of the U and fixed in the walls of' the tube 23.

The modified form of the invention shown in Fig. (i is similar to that shown in Fig. 2, but instead of the plug 31 having one transverse hole and a single pair of friction shoes, there are two transverse holes arranged at right angles to each other, and two pairs of friction slices 32 positioned therein. The friction shoes have inclined back faces against which the tapered end of an axially disposed plunger 33 bears to force them apart. The plunger 33 has a stem which is guided in the inner collar or bushing 34 in the tubular inner member 13, and a spring 35 which surrounds the stem of the plunger 33 bears against this bushing 34 and against the head end of the plunger 33 and presses the latter againstthe inclined faces of the friction shoes.

When the window is swung open (as shown by dotted lines in Fig. 1) the two portions of the adjuster rod are pulled apart, the frictional contact of the shoes against the inner surface of the tubular casing not being sufficient to prevent such movement. The spring is made of such strength as to cause sufficient friction between the friction shoes and inner surface of the tubular casing to hold the window in adjusted position against ordinary wind pressure or similar forces tending to open or close the window.

It is noted that all of the moving parts of the device are housed in the outer tubular member and are complete] protected from Y dust, water, and accidenta displacement or injury. Moreover, the location of the adjuster wholly within the groove in the top rail of the window sash com letely protects it when the window is closed? and it cannot interfere with screens, awnings, or other fixtures either in closed or in open position of the Window.

It is evident that modifications in the shape of the tubular casing and shape of the frictional face of the shoes may be made without departing from the invention; and

the invention is not restricted to the particular forms and arrangements shown and described.

I claim ther following as my invention:

1. A retainer for swinging windows and the like. said retainer comprising a tube and a rod slidable within the tube, said rod having Aa transverse hole through its inner end, a pair of friction shoes held in the ends of said hole, and spring means in said rod between said shoes for pressing said shoes ontward against the inner walls of said tube.

2. A retainer for swinging windows and the like comprising two telescoping tubes, the outer tube having a bushing fixed in one end slidably fitting around the inner tube and the inner tube having an extension at its inner end loosely fitting within the outer tube whereby said tubes are maintained in alinement, said extension having a transverse hole in the ends of which friction shoes are arranged to bear against the inner walls of said outer tube, and means within said inner tube for pressing said shoes apart.

, 3. A retainer for swinging windows and the like, said retainer comprising two telescoping members, the inner member having a transverse hole through its inner end, a. friction shoe arranged in said hole to bear against the inner wall of the outer telescoping member, and spring means in said inner member bearing against said shoe for maintaining it in frictional contact with said outer member.

4. A swinging window having a groove in its inner edge at its top, said groove extending from the hinge edge of the window toward the free edge thereof, an extensible adjusting rod' pivoted at one end to the bottom of said groove at its end away from the hinge edge of the `window and pivoted at the other end to the Window frame near they hinge end of the groove, said last named pivot being spaced from the hinge edge of the window a distance somewhat greater than the thickness of the window, whereby said adjusting rod will be substantially protected in said groove in both closed and open positions of said window.

Signed at St. Louis, Missouri, this 15th day of November, 1915.
