LOCK-HINGE.
SPECIFICATION forming. part of Letters Patent No. 249,304, dated November 8, 1881.
4 Application tiled August17, 1881. (Model.)
To all whom it may concern:
Be it known that I, CHARLES B. CLARK, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Hinges for Window-Blinds, of which the following is a specilcation.
My invention relates to that general class ot' hinges which, when the blind is thrown open, lock it in that position, theLblind being closed by forcibly causing it to rise on the pintle of the hinges and swing past the locking shoulders or inclines.
The object ot' my invention is to improve the construction and operation of hinges of this general character.
Ihe construction ot' the hinge will be fully hereinafter described in detail, and the improvements specifically pointed out in the claim.
In the accompanying drawings, illustrating my invention, Figure 1 is a front viewot' the improved blind-hinges, shown as being connected with the stile of a shutter and jamb of a window, the shutter being closed. Fig. 2in a perspective view of the leaf carrying `the fenlalevportion ot thehinge. 1 Fig. Sis a perspective of the leaf which carries the pintle or m ale portion of the hinge. Fig. 4 is a rear view of the hinge applied as in Fig. `,showingthe shutter open and hinge locked.
The letter A indicates the male portion of the hinge which is to be secured to the jamb or side of the window. The upper end, b, of the pintle B is cylindrical and the remainder is rectangular in cross-section, the portion marked b being conical. That portion c ofthe knuckle or bracket C between the. pintle and the leaf D is elevated or formed higher than the remaining part, o', and there is an incline, d, leading from the lower part, c, tothe higher part, c. The eye E of the female part F is of a conical shape corresponding to the conical part of the pintle, and the knuckle or bracket Ghas a flange, g. the end g of which is inclined. Thebracket C is notched at ll, to permit the lug t on the other portion of the hinge Vto pass in putting the hinge together, as is usual. i
When the blind is thrown back, as shown in Fig. 4, the eye lits down over the conical part of the pintle, the square faces of the eye and pintle being in contact. Thislocks the blind, and it can only be lmoved by forcibly pulling it, when,the faces in the eye being thrown against the angles or corners of the conical part of the pintle,ithe blind will rise until the eye reaches a point on the pintle of a sufficiently small diameter to allow it to move past the angular corners, when it will again sink onto the pintle and lock the blind in the half-closed position shown in Fi g.2. When the blind is drawn from this position to close it the eye will again rise, as just described, until the ange g rides upon the raised portion c of the bracket C, atter which the movement of the blind will be perfectly horizontal, the ange g and elevation c giving it a perfectly level support. This last movement ofthe hinge is facilitated by the inelines c and g', which aid in raising the ange onto the higher part, c, of the bracket C.
It will -be observed that the only motions that the eye has on the pintle are rotary and vertical, and that there is no lateral movement of any of the parts.
I do not broadly claim ablind-hingeconstructed with an angular base to its pin or axis, and withan angular socket part way through its sleeve, adapted to lit down over the angular base of the pin or axis, as such is not new with me 5 but Y i What I claim is- In a blind-hinge,the combination of the male portion of a hinge, having the raised part c and aconical polygonal pint-le, with the female portion having a conical polygonal eye and ange g.
'In testimony whereof I have hereunto set my hand in the presence of two subscribing wit. nesses.
