IMPROVED CURTAIN-FIXTURE.

dip Salaris nicht tu in tipst ttttas atcnt nur mating peut nt tigt anna ',IO ALL WI-IOM IT MAY 'CONCERNV De it known that I, JAMES CHASE, of Rochester, in the county of Monroe, and State of New York, have invented a certain new and useful Improvement in Curtain-Fixtures; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part ci' this specification. Y l

Figure l is an elevation of thc'arrangement as applied to' the sash.

Figure 2, a view in the same position, with the bearing of the right-hand h xturc in` section.

Figure, a side elevation of the right-hand fixture. i

Figure 4, a similarelevation of the left-hand fixture.

Like letters of referencclindicate corresponding parts in all the figures.

The object of my invention is to so construct and arrange the parts composing the fixture that no fitting ner manipulation is required after casting or cleaning, but the parts fit easily and accurately together; the righthand fixture being so arranged that the simple drawing out of the curtain-roller, bythe operating-cord, will allow the curtain to fall, and the left-hand fixture being so arrangcdas to retain thejournal of the curtain-rod in place under all circumstances. V

In the drawings, A represents the curtain-rollei,'and .B B the bearings or castings in which the journals rest. lThese bearings are cach provided with an open bevelled slot, ct, for the attachment to the sash, by means of screw Z1 tting therein, and also with a sere\v-hole, a', at right angles te a, for the purpose of attaching to the casing when desired. The right-hand bearing B has an extension, c, with an open slot, d, and a concentric shoulder, f, as clearly shown in gs. 2 and It also has a concentric slot, g. In the slot d rests the bearing 71. of a lever, C, the same being reta-ined in place by abit, z', which projects through and turns past the slot. This l'everis also provided with a bearing, 7c, in which rests thc journal of the curtain-roller, which said journal may project through so as to strike into concentric slot g to gauge the outward throw of the curtain-roller.

' The bearing 7c also fits under the shouldcrf, which keeps ithfrorn rising when in action. The lower end of lever C has a loop, Z, through which runs the operating-cord D that winds on the curtain-roller. To the right-hand end of the curtain-rod is rigidly attached a wheel, E, provided with ratchet-teeth m, which engages with a projecting detent, n, of the casting B, as clearly shown in iig. 3.

By this arrangement, it will be perceived that the curtain is held elevated at any position by the catching of the ratchet-wheel on the detcnt, and it is released at any time by simply drawing the cord out, thereby disengaging the ratchet-wheel, as indicated by the red lines, fig. 3. i i

This method isfar superior to that where theratchet-wheel is xed in position, and a pawl is thrown out of gear to release the curtain, inasmuch as -in my case the whole weight of the curtain and its roller acts by grfnvity to throwback again into engagement the moment the cord is released, while in the other case the swinging pawl is sol light in weight as to make it very uncertain in its action, and it is found almost impossible to stop the curtain at the desired position. If the pawl is weighted to' produce thedesired effect, the cost is increased, and the device becomes awkwardA and cumbersome. By thus taking advantage of the Weight of the vroller and curtain to produce the desired quickness of movement, I make the cost very small, and do not encumber the apparatus at all. This is a very' great advantage. v

-In'addition to this special feature ofthe throwing out of the curtaimroller to discngagc it, the construction of the bearing Band lever C, and their connection, present seme features ot' advantage, viz, the two slots a a' enable the bearing to be attached to either the front sash or the side casing. The extension c furnishes both the eye or slot d for the connection of the lever, and theconcentric shoulder f to hold said lever down in. action; and the lever C, formed with the bit c' and bearing 7c, is specially adapted to the above construction of the casting. These parts thus formed, fit accurately together after casting and ruttling, withouttitting or manip`- ulation-an effect, so far as I am aware, entirely new. By this means, the parts are connected, and the end of the curtain-rod applied in a moments time, and without any trouble. Y i

The only feature of peculiar-ity in the left-hand bearing B (except the slots a a', as before dcscribed,) is the employment of a projecting` flange on the inside, consisting of a roof-er covering, p, and socket p', with passage q between for the entrance of the journal r. When this journal is in place, it is retained against displacement by reason of the scroll-like form of the flauge,. which will not allowv its escape. At the same time, the application and removal, when desired, are perfectly free and easy. This arrangement has a special connection with the right-hand bearing, inasmuch as it allowsv that end to be first connected, when the leftfhaml end may also be connected at once. A

I am aware that a. pivoted pawl has been so"eonneeted witha fixed ratchet-wheel as to he thro'wn out of' engagement by means of a cord, and thus release the curtain-roller, but such I do not claim. l What I claim as my invention, and desire to secure by Letters Patent, is-

Connecting the end of the curtain-roller with a swinging lever, C, so ns to he thrown out bodily, and combining therewith the ratchet-wheel E and lletent n, in such a manner that the weight of theroller and curtain themselves serves to re-engagc the parts when thus thrown out, substantially as herein set forthr I also claim adapting the bearing B and lever C, without fitting, by means of the extension c, with sloti and shoulderf ofthe former, and the bit z' and bearing l: ei' the latter; the whole arranged and operating in the manner and for the purpose herein set forth.

I also claim the scroll-flange 27 p of bearing B', arranged as described, and operating in the manner and for the purpose set forth. l

In witness whereof, I have hereunto signed my naine inthe presence of'two subscribing witnesses.
