Specification of Letters Patent.
Patentedduly 7, 1914.
Application filed February 5, 1913. Serial No. 746,333. 6
To all whom it may concern:
Be it known that we, ROBERT S. FRARY and WALTER W. MACFARREN, citizens of the United States, residin at Pittsburgh, in the county of Allegheny, btate of Pennsylvania, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification.
Our invention relates to sash holders for Referring to the drawings ;Figure 1 is a vertical section through a portion of a window frame and its associated sash showing side elevation of our improved sash holder in operative position. elevation of the spring. Fig. 3 is an end elevation of the fluted roller. Fig. 4 is a side elevation of the same. Fig. 5 is aside elevation of the pawl. Fig. 6 is an end elevation of the same. Fig. 7 is a side elevation of a portion of the spring showing a modified form of lug attached thereto. And Fig. 8 is a cross section through the spring and its lugs showing the method of inserting the roller.
The window frame 1 is provided with a thin working strip 2, preferably made of vulcanized fiber or similar non-metallic material which is not affected by the weather.
The sash 3 is provided with a recess 4, this recess being somewhat less than the thickness of the sash as will be readily understood, and within this recess we mount our improved sash holder, which consists of three main elements, a bowed spring 5, a fluted roller 6, and a pivoted pawl 7. The
7 spring 5 may be stamped from sheet steel of proper quality, and may be of uniform thickness throughout, or it may be of tapering section, being thicker in the middle.
The spring 5 is provided with a flange 8 at its upper end which abuts against the upper surface 9 of the recess 4. At the upper end of the spring just below the flange 8 a hole 10 is formed, and at the lower end of the spring there is an elongated hole or slot 11. Screws 12 and 13 fasten the spring to the sash. A pair of lugs 14 are formed on the middle portion of the spring and are preferably integral therewith. Each 111g 14.
Fig. 2 is ans is provided with an upper hole 15 and a lower hole 16, these holes being opposite each other in the adjacent lugs.
The roller 6 is provided with integral journals 17 for which the holes 16 form bearings. The pawl 7 is provided with similar journals 18, for which the holes 15 form bearings.
In the manufacture of, the spring 5 one of the lugs 1 15* is bent to a right angle with the body of the spring, and the opposite lug 14 is bent to such a position that the journal 17 of the roller 6 can be inserted in the hole 16 before the finishing bend is given to the lug 14 The journals 18 of the pawl 7 are engaged bythe holes 15 at the same time.
The roller 6 is provided with fluted or grooved surface as shown at 19. These grooves are formed with a radial side 20 and a curved portion 21 which connects with the cylindrical surface 22 of the roller. As flutes 22 are comparatively small and few in number the smooth actionof the roller is not interfered with. It will be noted by reference to Fig. 1 that the parts are so assembled that one of the portions 22 of the cylindrical surface of the roller bears against the working strip 2 when the pawl 7 engages one of the flutes 19 so that the sash can be moved downwardly without any scraping action being produced by the roller 6 on the working strip 2.
In Fig. 7 we have shown a portion of the spring 5 and a modified form of lug 23, there being two of these held together by a connecting piece 2 1, the same being connected to the spring 5 by rivets 25. lVhile this construction serves the same purpose as the one shown in Fig. 1, it is more expensive to make and only of advantage when very heavy springs are to be employed. In Fig. 2 we have shown in dotted lines the outline of the lugs 14: as they are punched from the sheet before being bent. It will be observed that by forming the lugs 14: integrally with the springs 5, and by forming integral journals on the roller 6 and the pawl 7 that the entire device with. the exception of the fastening screws is composed of only three parts, and is so assembled that the parts cannot under ordinary circumstances become detachedor alter their relation with each other.
The use of a fiber working strip insures a uniform smooth track, having a surface well adapted for the frictional engagement of the roller in that it has a high co-eflioient 7 spring adapted to be secured to the sash in a recessed portion thereof, lugs carried by said spring, two sets of holes insaid lugs,
a fluted roller provided with integral journals engaging one set of holes, and a pawl also provided with integral journals engaging the other set of holes. I
2. A sash holder comprising a bowed spring adapted to be secured to thesash in a recessed portion thereof, lugs formed integral with said spring and projecting therefrom, a fluted roller carried by said lugs, and a pivoted pawl also carried by said lugs and engaging said roller.
3. A sash holder comprising a bowed springadapted to be secured-to the sash in a recessed portion thereof, a roller carried by said spring for engaging the. window frame, a pawl carried by said spring to prevent rotation of the roller in one direction, anda flange formed on the upper end of said spring to abut against the upper surface of the recess in the sash. I
4. A sash holder comprising v a bowed spring adapted to be secured to the sash in a recessed portion thereof, outwardly and upwardly extending lugs carried by said spring, and a roller and a pawl carried by said lugs. I
5. A sash holder comprisingithree members, viz., a roller, a pawland a spring, said roller and saidpawl being mounted on said spring, and means for securingthe device to a wlndow sjash.
In testimony whereof we hereunto affix our signatures in the presence, of two wit-j nesses.
