Letters` Patent Y 100,486, dated March 1', -1870.

IMPRQVEMENT IN Sasa-HOLDERS.

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

First, theinvention consists ill constructing applate with openings to receive a send-elastic roller, oi'a less length than the diameter of the roller. Through this opening the roller is wpressed, the space illcreasing in length inward, so tllat, when the roller reaches its working position, roolll occurs for it movements, as and for the purposes hereinafter set forth, the object being to hold the roller trom falling out, &c.

Secondly, ill colllbillillg witll this plate the curved end corresponding with the curve of'the roller, the object being to enable Athe elastic surface of the roller to touch this surface throughout at the same time, alld receive from it the amount offrictioll required to hohl the sasll. Tile limited angle of this tiiction-surtilce with the line of pressure prevents the entire clamping ot the roller, 86e.

Thirdly, ill the construetionaud use of a roller'whose surface is composed of a combination of metal and rubb'er, or porcelain and rubber, &c. The rubber l'cceives the friction from the plate, alld, ill combination with the. metal surface ofthe roller, furllislles the frict-ion on thccasing, the object beillg to prevent the Vsliding of the rubber on the casing, and consequent destructioll of'its ronndlless alld eftieiem-y.

General Description.

A, roller-plate, with openings for rollers, of less length than` the dia'lneter'of said rollers. Through these openings the rollers are pressed alld held. By duplicating these openings any required nllnlber of rollers may be used ill one plate.

B and B', journal-rests for holding the roller ill its position. A substitute for tllese may be obtained by using instead the surface at the feud, marked G, so

surface of the roller.

that it will tollcll the rolle-r, and then slope rapidly away from it, Ste., down 'ard and outward. While this would afford some resistance in raising the sash, the angle of resistance would be so small that this would hardly be perceptible. By carrying the projections B and B' up to the top line 'of the plate, alld placingthe journals of the rollers against them, and pressing the rubber susface past the curved elld in thc opening at D, a result similar to compressing through a short opening ill the plate would be obtained, but still by compression, 85e. y

I), curved surface-end otlopening of plate Av, against wllicll thc roller acts during the downward movement ofthe sash, audowllile the saule is held supported, tc. The curve of this surface corresponds with the 4curr-ed Tllis surface may extend above the plate or not.

E, section ofthe window holding the sash-holder.

F, semi-elastic covering of roller used ill combina.- tioll with a metal surface, 85o. This covering is vnl- 'callized suiieiently hard to prevent being pressed out of round by theaction of the springs, and also made white, to avoid discolol'ing thecasing, when desired. lt is lllade ill'the form of tubing, and lcut to the lengths required, Ste. Leather could be used for this purpose also.

. G, metal or porcelain surface ofthe roller in combination with the rubber. This, when Vonly one is used, as ou the en d or ill the center, may be cast tight on tothe body of the roller, as illustrated ill tig. 6.

When more than-one, they may be ill the form of eollars or washers, 86e.

The surface of this surface is roughelled ill imitation ot' a nlilledsuriilcc, to enable it. to hohl on to the. casing, and, ill combination with the rubber surface, support the sash. The rubber surface of the roller receives its sumlol'ting-power flllu the curved surface of t-lle plate, the llletal portion nlovillg through the plate freely by means of the `groove or grooves on reither side, 85e., and the rubber `and milled surface hold the sash ill any position desired. The llletal surface prevents the roller fronl sliding, compelling it to turn when it is desired to press the sash down.

. G', body of the roller, over whicll the elastic covering is drawn. 1t may be grooved or roughened to prevent the rubber from turning, Ste.

H alld H', double-acting sprillgs, constructed so as ,to elongate and spring botll ways or in opposite directiolls. This form of spring reduces the leverage witllont reducing the springing surface, and requires much less space ill theglnortise to work ill, and also possesses elciellcy tor-the purposes intended.` One of tllese is used between the lastening-screws and end of nlortise, under each end of plate A, and remain in position without fnstenings, 8m., keeping the roller in contact 2. The combined met-ai and elastic-surfaced roller with the casing, and overcoming eiectually the veffects herein described, the metai extending so as to catch ofshrinknge, Sto. upon the casing, and combined with groove for the J :uid J, common wood-screws, used for securing metal to run in, amd a. friction-surface in pluto A. plate A iu its proper pince in the mortise. 3.
