SASH HOLDER.
No. 448,339. Patented Mar. 17,1891" Fig.1.
UNITED STATES PATENT Urricn.
\VILLIAM M. HAZEL, OF GEORGETOWN, DELA'WARE.
SASH-HOLDER.
SPECIFICATION forming part of Letters Patent No. 448,339, dated March 17, 1891.
Application filed May 2, 1890. Serial No. 360,364. (No model.)
To aZZ whom it nmy concern:
Be it known that 1, WILLIAM M. HAZEL, a citizen of theUnited States,residin g at Georgetown, in the county of Sussex and State of Delaware, have invented a new and useful Sash-Holder, of which the following is a specification.
The object of my invention is to provide a simple and effective sash-holder-one that will adjust itself and be held in place without the necessity of grooved notched slots, adjustable tables, springs, or other movable devices in order to get proper bearing.
The invention consists in the peculiar for- 5 mation of the box, and also in the novel construction of the wheel or ball which plays freely in the same, all of which will be more fully set forth in the specification, and shown in the drawings, wherein- Figure 1 represents a section of box and its inner walls on line 1 1 of Fig. 3, with the wheel or ball in position. Fig. 2 represents a similar section 011 line 2 2, with the wheel or ball in a bearing position in said box. Fig. 3 repsents a front view of the sash-holder complete.
Fig. 4. represents a side view of box and wheel or ball in bearing position. Figs. 5 and 6 show modified forms of wheel or ball shown in Figs. 1 and 2.
Similar letters of reference indicate like parts in the several drawings.
My invention is made of metal, and the box B is constructed with vertical outside walls and grooved inside walls, with its rear wall flattened fora portion of its width and somewhat inclined, as shown in Fig. 4 of the drawings. This box is preferably cast in two pieces and fitted together at the point shown by the lines I) in Fig. 3, or it may be cast in one piece,
4 as desired,the result being the same in either case. \Vheu so cast in two pieces, the front edge of one member is provided at its upper end with an inwardly-extending tongue 6, havin g a hole 72, through which is passed the screw that holds the box in the sash, and the other member has a similar tongue at its lower end. The wheel or ball A may be made of metal or molded from a composition of hard material, it being only necessary that it shall have 5 no elastic properties. In shape it is spherical at the parts lettered a, which fit in the grooved I placed.
inner sides or walls of the box B, as shown in dotted lines in Fig.3 and in full lines in Flgs. 1 and 2, and it is provided at the points lettered a a with a raised, rounded, flattened, or angular'faced ring, which rests against the rear wall of the box 13 and against the edge of the window-frame if the box be seated in the sash, or against the sash if conversely This ring is comparatively narrow- 6., narrower than the edge of the sash or the groove in the frame in which the sash moves as will be seen from the drawings, and hence when a considerable strain is brought to bear upon the ball it will sink into or 111- dent the sash or frame.
In operation, the parts being properly placed in a window, the wheel or ball A rolls freely up and down in the box B when moving the window up or down, and when pressure is taken off the sash the wheel or ball A drops readily into a bearing position against edge of sash. The wheel or ball A being made slightly raised at the points a Ct, it w1ll be observed, is a great improvement, because 1n use, being narrower than the edge of the sash, it will gradually embed itself in said sash or frame, and thus increase its holding qualities, as Well as positively prevent the rattling of the window.
I show'iu Figs. 5 and (3 modified formsof my invention. which may be employed with the box without departing from the spirit of this'invention, as the results are identical.
It will be observed that my invention by reason of the grooved inner side walls of box and novel construction of wheel or ball gives such a stubborn resistance all around the grooved walls and the ball as to compel the sash to remain in position desire-d when the wheel or ball is at rest against the indented edge of sash, thus forming a very strong attachment and one that cannot get out of order or become detached. At the same time it adjusts itself from time to time as the window may shrink or swell. These features are decided improvements, which will be readily appreciated by builders, because when once set the job is complete, as no future ad ustment becomes necessary.
Heretofore much difficulty has been experienced in devices of this character, owing to the crushing or breaking of the boX if the sash were forced strongly downward when held by the ball. This was owing to the fact that where spherical balls were used theybore at but one point against the box and where the balls were cylindrical they bore only across a single line. The box being generally of light casting was easily crushed if too great pressure were brought to bear thereon; but where the spherical faces a a travel in grooves in the side walls and the raised faces a bear squarely against the rear wall of the box a double, or rather triple, bearing or resistance is provided in the box, the spherical faces wedging the sides of the box outwardly and the flat face driving its rear wall backward. The strain resulting is therefore distributed over a considerable part of the box and exerted in three directions, and the result is that the box is much less likely to be broken or crushed.
against said rear wall and extending beyond the front of the box when in its operative position, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
\VILLIAM M. HAZEL.
