ISAAC DAVIS, OF GROTON, NEW YORK.

HINGE FOR SHUTTERS.

Specification of Letters Patent No. 14,349, dated March 4, 1856.

To all whom it may concern:

Be it known that I, IsAAo DAvIs, of Groton, in the county of Tompkins and State of New York, have invented certain new and useful .Improvements in Hinges for Shutters, Blinds, &c.; and I do hereby declare that the same are described and represented in the following specification and drawings.

To enable o-thers skilled in the art to make and use my improvements I will proceed to describe their construction and operation referring to the drawings in which the same letters indicate like parts in each of the ligures.

Figure 1 is atop view of the hinge with a section of the window frame and a portion of a blind. Fig. 2 is an elevation of the hinge upon the frame and blind.

The nature of my invention consists vin making a score longitudinally in the hole in the hinge in which the pin is inserted that connects the movable part, to the stationary part of the hinge; the score in the movable part being made so as to correspond with the score in the stationary part, when the blind which is hung with the hinge is half way open; so that a pin with a rib or feather on that part of it which corresponds with the middle or lower section o-f the hinge fitted to the score, can be inserted to fasten the hinge together, or removed so that it can be separated, but if the movable part of the hinge is changed or turned either way, after the pin is inserted, it prevents the pin from being removed until it, the movable part, is brought into the same position again. in which the pin was inserted. Also in a segment on the movable part of the hinge provided with teeth of a peculiar construction, adapted to a. conical screw arranged in rear of a radial line from the center of the pin of the hinge.

In the accompanying drawings A is the stationary part of the hinge fastened to the window frame B. This part of the hinge is made in two pieces as shown by the line c, each part being provided with a semicircular score for the journal of the conical screw shaft D, and with a projection E, for the pin F, on which the movable part of the hinge G, turns as the blind H, to which it is fastened, is opened and shut. The holes for the pin F in the projections E, E, and the hole in the movable part of the hinge G, are provided with angular scores a, in

the stationary part and in the movable part represented by dotted lines so arranged that when the blind is half way open the scores in the several parts will correspond, so that the pin F, Fig. 3, which is provided with a rib or feather c, on that part which comes in the parts E, E, fitted to the score a., can be inserted' so that the movable part G, will turn on the middle portion d, of the pin F where there is no feather. This mode of construction prevents the removal 'of the pin F, when the blind is closed, so

as to remove the blind, so that the hinge is proof or secure against burglars and at the same time permits the pin F, to be removed with facility when the shutter is half way open. the portion d, of the pin and omitted on the other portions, it would answer the same purpose; when two projections E, E, are used; but if only one is used the feather should be on that part of the pin which is in the lower portion of the hinge.

The moving part G, of the hinge is made circular and provided with two flanges J, J, by which it is fastened to the blind or shutter, and the circular part is provided with teeth on a large portion of its edge made in the peculiar form shown in the drawing, so as to correspond with the thread of the conical screw 7c, which works into them, so as to open and close the blind by turning the screw which is provided with a shaft D, which has a square end fitted into the socket L, of the crank M, on the inside of the window frame, so that any person on the inside of the house can open and If the rib or feather was made onl close the blinds or place them in the posiv tion desired, without leaving the room or opening the window, and the conical screw will hold them in the position in which they are placed without further fastening.

The socket L, is provided with a flange N and is fitted to turn in the plate P, which is fastened to the window frame on the inside, so as to hold the socket and crank in a proper position to be turned, to operate the blind H. By making the screw 7c, conical and the teeth on G, in the form shown I am enabled to place the screw within the plane of the outside surface 'of the window frame, or behind the radial line e drawn from the center of the pin at a right angle to the shaft D, of the screw, so that the screw is entirely inclosed and protected from the weather.

Screws and gears as commonly constructed Will not Work Well together if at all, unless the screw shaft is placed so that a radial line from the center of the gear at a right angle to the screw shaft bisects the screw; and when constructed in that manner the screw has to be placed outside of the Window frame where it is exposed, and is liable to be covered with ice so that if an attempt Was made to operate it, it Would break or derange the parts. However when so constructed they are covered by au eX- pensive and unsightly case; and to avoid both of the abovementioned defects I have been induced to make the screvv conical as described and the teeth of the Wheel in the peculiar form shown so that they Will oper- ISAAC DAVIS.
