UNITED STATES ATENT Tirreno FRED H. MOORE, OF HOLBROOK, MASSACHUSETTS.
SHUTTER- WORKER.
SPECIFICATION forming part of Letters :Patent No. 246,186, dated August 23, 1881.
Application filed March 14, 1881.
To all whom it may concern Be it known that I, FRED H. MOORE, ot' Holbrook, county of Norfolk, and State of Massachusetts, have invented a new and useful Improvement in Blind-Hinge, of which the following description, in connection with the accompanying drawings, is a speciiication.
This invention has for its object a novel construction ofblind-hinge, whereby the saine may be operated from the interior of the building, and be locked or held in any desired position, either closed or partially or fully opened. y
In a device embodying my invention that part ot' the hinge which is secured to the blind has a plate provided with a series of tapering pins arranged in a circle, and which are engaged by a worm at the end of a shaft having' its bearings in that part ofthe hinge which is secured to the window-casing. The shaft carrying the said worm is extended through the side ot' the building or casing into the interior ot the building, where it is provided with a handle, by which the said shat't and worm may be rotated in one or the other direction to cause it to open or close the blind. All this is common and old in shutter-workers ofearlier date.
My invention consists in the improved construction and arrangement of parts, whereby the device is rendered more durable and eii'ective than the earlier ones.
Figure l represents, in side elevation, a sufficient portion of a blind-hinge and blind and casing to illustrate my invention, and Fig. 2 is a front view thereof'.
In the drawings, a represents a portion of a window blind or shutter, and b a portion of the window-casing. The hinge represented is that which is adapted to be applied to the lower end ofthe blind. That part, c, ofthe blind-hinge which is to be applied to the blind by screws d has a pintle, e, to enter a socket, f, project- (No model.)
ing from that part, g, ofthe hinge which is attached by screws h to the window casing or frame b. cular plate or cap, ,-provided at its underside with an annular series ot'tapering pins or teeth, j, which are engaged hy the tooth of the worm la, secured to the end of the shaft l, havingits bearin gs in an ear, m, of the part g ofthe hin ge, and also in a projection, n, extended backward from the hinge party into the casing b, as shown in Fig. 1, the inner end ot' the shaft l wit-hin the building having attached to it the handle or crank 19, by which the shaft land worin may be turned in one or the other direction, causing the'tooth of the worm to engage the conical pins or teeth j of the plate t' of the hingepart c, and positively open or close the blind a, the blind being held or locked by the said worm in any position in which it may be left by the shaft l. The plate i prevents snow from being deposited upon the worm lr. The weight of the blind to which the hinge part cis connected keeps the pinsj pressed down into engagement with the tooth ot the worm.
I claim- The improved blind-operating hinge herein described, consisting ofthe part c, having the pintle c and toothed cap t', combined with the part g, having the rearward projection n and ear lm, the worin 7c and its shat't Z, supported in and by such projection and ear, and in operative connection with the cap i, and the socket f to receive the pintle c, all constructed and arranged as shown.
In testimony whereofI have signed niy name to this specification in the presence ot two subvscribin g witnesses.
FRED H. MOORE.

The part c of the hinge has a cir.
