BLIND-HINGE.

Specification of Letters Patent. Patented June 22, 1915,

Application filed July 8, 1914. Serial No. 849,789.

To all whom it may concern Be it known that I, JAMES W. TATUM, a citizen of the United States, residing at Coats, in the county of Harnett and State of North Carolina, have invented new useful Improvements in Blind-Hinges, of which the following is a specification.

This invention relates to hinges and particularly to a novel form of hinge upon which outside windowblinds are hung, and has for its object to provide hinges that will permit blinds when thrown open to bring their outer edges close against the building and to automatically lock the blinds in this position and prevent the same from being closed by violent winds. The locking device on each hinge while maintaining the blind in its open position may be disengaged when desired with little trouble and the blind closed.

In the accompanying drawing, Figure 1 is an elevation of a pair of hinges applied to a blind and its window casing with the blind closed. Fig. 2 is a sectional view on the line 22 of Fig. 1. Figs. 3 and 4 are similar views with the blind in different positions, the former being partly open and the latter entirely open and locked. Figs. 5 and 6 are perspective views of the two hinge members.

In the drawings, A indicates a portion of a window casing and B a portion of a blind, on the former of which is fastened by screws a hinge member 10, and on the latter a cooperating hinge member 11, the two members lapping and pivotally connected by a pintle 12. The hinge members are each made entirely of sheet metal stamped or otherwise cut into shape and bent at right angles as shown to form a vertical plate 13 through which several holes are made to receive the fastening screws. The horizontal plate or portion 14 of the member 10 is formed with a notch 15 in its outer edge. and a tongue out from the body of the part 14: and bent upwardly to form the pintle 12. The edge 19 of the portion 14 from the notch 15 around the pintle for quite a distance is substantially concentric to said pintle for a purpose to be described later. The horizontal plate or portion 16 of the member 11 has an elongated slot 17 therein that fits over-and turns around the pintle 12 and permits the hinge member 11 to move horizontally at the proper time with relation to the member 10. The portion 16 is 15 looks the blind when the'latter and 2 the tongue 18 will stand a short distance away from the edge 19 of the plate 14, but as soon as the blind is pushed open the weight thereof will cause the plate 16 of the hinge member 11 to move over the plate 1-1 of the member 10 until the tongue 18 bears upon the edge 19 of the plate 14, the slot 17 in the plate 16 permitting this movement. lVhen the blind has been swung open until substantially parallel with the side of the building as in Fig. 3 the lug 18 will pass from the edge 19 of the plate 14 and be arrested by the rear edge of the notch 15. The weight of the blind when in this position will cause the hinge member 11 to slide over the member 10, the slot 17 being sufficiently long to permit this, and guided by the tongue 18 bearing upon the rear edge of the slot 15 the blind will swing into the position shown in Fig. 4 standing at an angle to the building with its free outer edge bearing close against the wall. The tongue 18 is carried into the notch 15 by this movement of the blind and hinge member 11 and its weight is sufficient to hold the tongue therein under normal conditions. said tongue being held between the front and rear edges of the notch 15 preventing the blind closing unaided, the tongue in fact being locked in the notch 15 by the weight of the blind.

The blind may be readily closed by pushing outwardly against the stile thereof until the tongue 18 is disengaged from the notch. and holding the same in this position until the blind is swung sufliciently far to cause the tongue to bear upon the edge 19 of the plate 141, after which the blind mav be closed without effort.

What I claim is 2- A hinge comprising two parts adapted to be stamped from sheet metal each of said parts having an outwardly projecting horizontal bearing plate of substantial area. one of said plates being attached to a fixed member and the other to a swinging member, the plate on said swinging member being adapted to overlap and frictionally slide upon the plate on said fixed member whereby the weight of the swinging member is supported by the latter plate, a vertical pinthe moving member is fully open, said tongue being aclapted :to be retained in said notch by the weight of said swinging memberl'toflock the parts open.

In testimony whereof I have hereunto set any hand in presence of two subscribing witnesses. H

JAMES WILLIAM TATUM.
