To ALL To wHoM 41r MAY coNcnRN: i

Be it known that I, GEORGE ALLIX, of St. I-Icliers, Jersey, one of the islands in the British Channel, shipfl wright, have invented or discovered certain Improvements in Apparatus for Raising and Lowering Window- Blinds, Windows, Maps, and other Articles, andv retaining them' in any required positiong and. I do hereby declare that the following is a true and exact description thereof, referencebeing hadto the accompanying drawings and Vto the figures and letters marked thereon; that is to say,

My invention relates to theuse of chain in raising and loweringwindow-blinds mounted on rollers, and consists mainly-in the construction and employment, as hereafter described, in combination with a chainA of ya I slitor cut, into which the chain enters when left to itself, so that the chain is held in the slitA and the blind- -roller prevented rotating; also in the combination, with the slit or cut, of other parts, as hereafter described.

In carrying out this invention, I secure to the lower part of the side of the window-frame a-bracket-or cleat, the upper portion of which carries a pulley, while in the lower portion a slit -or cut is made to catch or nip the chain. A

vFigures 1 and 2 represent such a bracket in front and side views.

a is the bracket, I; thepulley, and e the slit or cut-l Fig. 1 shows a. window-blind with thel bracket applied to the window-frame. The upper end of the chain d is secured to a pin, e, en the end oi' the blind-rollerj', and is led down through an eye, g, and through the pulley b of the bracket or cleat. The circumference of the pulley b is, say, halt` an inch nearer the-'windowframetban the slit c. .-To raise the blind, take hold of a ring or handle, it, on the lower end ofthe chain, keep it out from the window-frame, andhaul on it, keepingthe chain always taut, and when desired to stop the blind, let go the chain suddenly or close it towards the frame, and one oi' the links will be caught in the slit c. To lower the blind, pullout the handle It, asbeforc, let the chain run, but keeping itwalways taut, and when required to stop the bind let the chain catch in the slit as before. Sometimes I fit to the bracket a a lever, t',

pivoted to the bracket behind the pulley b, as seen in Figure 3, by lifting which on its pivot intothe position shown in dotted lines, the chain d is moved out of the slit c, and the blind runs down of its own weight until the lever is released.

Another arrangement consists of a plate, a, as seen in Figure 4, secured to the window-frame, having a double lug, k, at the upper part, and a double lug, Z, at the lower part.. Each lug has a pulley, e, fitted init, but the lower lug l is, say, halt` an inch longer than the upper, and has a slit or cut, c, to catch the chain,'as before explained. i

Another arrangement consists of a plate, a, Figure 5, secured to the window-frame, and having two eyes,

lmet, one above the other-at its upper part. The upper eye m is plain, and takes the place of the pulley before described, and it-is as close as possible `to the frame. The lower eye n is, say, half an inch from the frame, and is formed with a slit or cut, c, to catch the chain.

Another arrangement4 consists of a screw eye-boltyshown at a in plan view in Figure 6, screwed into the window-frame, and having a shoulder, o, as short as possible. The eye is formed with u cut or slit, c, which is in this case at the part of the eye'farthest from the frame, and therefore thei chain d must be held towards the I frame instead of from it in raising or lowering the window-blind or, if theeye-bolt be of sulicient length, as

shown in Figure 7, the slit or cut Vc may be at the part Vof the eye nearest the frame. The pin e on the end of the blind-rollerf may be made to turn in a bracket, p, as seen infg'. 1, carried out from a plate, screwed to the window-frameor in an ordinary side bracket, and the bracket in either casehas an eye, as at g, iig. 1, car; ried out therefrom, to lead the chain from the roller-pin e, as before explained. Sometimes I tit a whelped bo`ss on the pin e for the chain d to pass round. v

The arrangements before described are equally applicable to maps and other articles mounted upon rollers.- In applying them to Venetian blinds, I employ above the blind a roller round the pin, on the en d of which the chain passes, as in tig. 1. The ordinary cords which pass through apertures in the laths arc connected' to this roller, so that when the chain is pulled, and the roller thereby caused to revolve, the-cords wind round the roller, thus raisingthe blind. When the chain is allowed to run, the weight of the blind causes the cords te unwind fromvthe roller while the blindiis lowered.

The arrangements can also be applied to carriage-windows and other frames and outside blinds, by'securing the upper end of the chain to the top of the window or other part to be raised or lowered, carrying itover a pulley above and over a second pulley at the sidc, about parallel Ywith the first pulley, and finally carrying it down to the apparatus before explained. This arrangement is represented in'Figure 8, Where the chain d is shown attached at one end to the top of a carriage-Window, then carried over two pulleys 'r s, and finally carried down to one of the catches or holding apparatus. p

the modications described the same features exist, namely, a slit to catch the links of tho chain, and a guide or pulley so situated in relation to the chain and slit that it causes the chain to fall by its own gravity into the slit when the chain is let go suddenly.

What I-claim as my invention, and desire to secure by Letters Patent, isf- 1. The combination of the slit, guide, and chain, arranged with reference to each other and a Windowblind, curtain, &c., so as to operate substantially in the manner set forth, the combination being substantially,1 such as described.

2. I claim the combination of the slit, guide, and chain with the lever, which, when lifted, moves the chain out of the slit, the combination being 4substantially such as herein set forth.

GEORGE AILIX.
