IMPROVEMENT IN SASH-HOLDERS.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, RoBnRTB. HUGUNIN, of the city, county, and State of New York, have invented a new Window-Sash Supporter, of which the following' is a specification.

Nature and 'Objects of the Invention.

This, invention consists in the combined use of two rollers, a lever, and two springs attached to-and working from a front fasteningplatethe two rollers .suspended in bearings in the lever, so as to move furnishing friction when the sash is stationary, and

llessening the wear of' the rollers'. n

General Description.

A, fastening plate, to which' the lever, springs, rollers, 85e., are attached before the `same is secured in the casing ofthe window.

B, movable leverfor conning the rollers, by means of the springs adjustingVv them to each other and the spacebetween the sashrand casing.

C, horizontal spring,\one end resting in a springsocket projection, extending `back from the front side of -plate A, and the other end supporting and controlling the lI'novable end of the lever B, and' furnishing the necessary pressure to the rollers.

D, vertical spring attached to the end of the lever B, and by means of it controlling the vertical movements of one of the rollers.

This spring is confined between .projections on the end of the lever and from rear-,side oi' plate A.

E, lever securing pin, passing through the projections from plate A over the lever, so as to cornh'ne it and at the same time allow i-t. to move under the influence ot thev springs, as required.

F, upper semi-elastic roller, with bearings in lever, .allowing it to rise up and down.

G, lower semi-elastic roller, with bearings confining itto a fixed position in the lever, and moving only with it by the elasticity of the vertical spring.

H and H', projections on the rear side of the plate A tor support the roller F and the weight of the sash.

These projections hold this roller and, allow the other one to be drawn from it by the yielding of the spring D in pressing the sashdown, &c.

I and I', fixed bearings in lever B for confining roller G.

J and VJ' open bearings for confining in a movable position the roller F.

The space between the bearings I and J is greater than the diameter of the roller, allowing them, by

the lifting of F, to roll clear of each other in raisingr the sash.

K, projection from plate A, for confining securely one end ofthe vertical spring D.

' Y L, spring-seat projection extending back from front -side of'plate A to a depth requiredto take in the spring'.

M, projection from one end of lever-B, which is passed through the opening in plate A from the rear to the front, and over the spring C, on which it rests,

Ifollowing the rollers back and .i'orth with the lever,

according to the space ing, &c.

' When the sash is at rest the two rollers are in contact with 'each other, and in turning the motion of the rollers is opposite at point of contact, and in this way the friction is furnished to support the sash in position lei't; aproper and eficient spring pressure being, of course, preserved to prevent the sliding 'of the rollers, &c`. l

.In pulling down the-sash the upper roller catches on the projections H and H', and is held there, while the lower' one, suspended by the vertical spring D, is drawn down sufficiently by the additional pressure and friction, from the upper roller to enable them both to turn, 82o.

between 'the 'sash and cas- Claims.

1. rIhe sliding lever B, in combination with the vertical spring l(L and horizontal spring D, substantially as setforth.

2.,'lhe 'plate A, having the confining-projections K and L and pin E, with the springs C and D, in combination with the lever B and rollers F and Gr, substan tially as described.
