IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. H70', [31, dated November 16, 1875; application filed october 30,1875.

To all whom it may concern Be it known that we, HIRAM ToEREY, of 'the city and county of Philadelphia and State of Pennsylvania, and DARIUs LYMAN, of

Y Washington city, District of Columbia, have invented a new and Improved Sash-Holder5 and we do hereby declare that the following is a f'ull, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which the figure is represented in elevation of our invention, the side ot' the case being removed.

The invention relates toa device designed for application to a window-sash, for the purpose of arresting and supporting the same by t'rictiona-l contact with the jamb.

The chiefl elements of `the device are a movable or adjustable -rubber wedge and an elastic roll mounted on a flXed pivot, the former being connected with a pivoted spring-lever, and so arranged as to adapt it for insertion between the roll and jamb, to lock the sash, as hereinalter fully set forth. 1

Referring to the drawing, A denotes a metal case, which is secured to the stile B, and incloses the working parts. The elastic roll C, mounted on the lixed pivot c, is composed of caoutchouc, or other elastic substance. A bent lever, D, is'` pivoted at b beneath the roll U, and projects through the side of the case A, as shown. The elastic wedge E is composed ofthe same material as the roll, andsuitably attached to a metal bar, c, which is pivoted to the inner end of the lever D. A spiral or other form of spring, F, is Varranged on the other side of the fulcrum b, to act on the lever, and thus cause the wed ge to tend to thrust itself` into the narrow space between the roll and jamb or window-frame.

Since the roll turns freely on pivot a. with each movement of the wedge, and the latter slides in contact with the jamb, there is slight friction on one side of the wedge, but excessive friction on theother. The effect is to cause the wedge to insert itself iirmly between the roll `and jamb whenever the sash moves, or tendsto move, downward, thus arresting and holding the sash by its binding action.

It is further apparent that in proportion to the weight, and consequent downward pressure, of the sash, the farther will the wedge thrust itself upward, by reason of `the increased friction between it and jamb. Hence,

and held out of close contact with the jamb,

when it is desired, to lower the sash.

It is unnecessary to operate the lever when the sash is to be raised, since the Wedge is then depressed by friction with the jamb.

yAs shown in the drawing, the wedge is in-` serted firmly between 'the roll and jamb, and

the sash is, consequently, locked in an elevated position.

The dotted lines represent the position of wedge and lever when the lock is broken, and the sash left free to be lowered.

In some cases we proposeto place the lever and wedge above the roll, so that the latter may operate to prevent the sash being raised. Y What we claim is Y 1. vThe combination, within a suitableshell or case, A, of a pivoted elastic roll, (l, and movable or adjustable rubber wedge, E, for working in contact with, and between, the jamb or window-frame and roll, substantially as set forth.

2. rlhe pivoted lever D, the spring F, the pivoted` bar c, and elastic wedge E, in combination with a rubber or other elastic roll, C, as shown and described, to operate as specified.
