SHUTTER PASTENER- Patented Feb. 23, 1892.
UNITED STATES PATENT OFFICE.
JOHN IIANDWERKER, OF MARLBOROUGH, MASSACHUSETTS.
SHUTTER-FASTENER.
SPECIFICATION forming'part of Letters Iatent No. 469,446, dated February 23, 1892. Application filed October 2'7, 1891. Serial No. 409,956- (No model.)
T at whom it may concern.-
Be it known that I, JOHN HANDWERKEE, of Marlborough, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in BlindFasteners, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of a portion of a window-casing, showing the blind as open, provided with my improved fastener. Fig. 2 is an elevation, enlarged, showing the fastener in position; Fig. 3, a transverse section of the lower frame-bar of the blind, showing the fastener in side elevation; and Fig. at, a like view showing the fastener elevated.
Like letters and numerals of reference indicate corresponding parts in the different figures of the drawings.
My invention relates especially to a springtensioned blind or shutter fastener; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the blind, and B the window-casing, to which the blind is hinged in the ordinary manner. Centrally on the lower frame-bar cl a right angle iron bar f is fittedto slidevertically in'an eye or loop g. The foot h of said bar projects horizontally under the frame-bar (Z, in position to engage the catch ion the wall of the building by the ordinary loop on the sill. The bar f is provided with a pin ,7 to prevent it falling through the loop 9, and above said pin, in the outer face of the bar, there is formed a semicircular groove 70. A plate on is secured to the frame-bar cl by screws 19, and from the face of said plate lugs q project. A lever C is pivoted in said lugs. Said lever is provided on the outer end of its long arm with a fingerpiece t, its short end 0' working in the groove 7c of the bar f. The foot h has its lower edge curved vertically at e, and two vertical slots 2) t" are formed in its edge, said slots being respectively adapted to receive the loop on the sill in the catch t' on the wall. The foot h is provided with a project-ion 15 on its upper face. A coiled spring 16 is disposed around said projection and in a chamber 17 in the sash-bar d, said spring acting expansively to force the foot downward into engagement with the catches.
In the use of my improvement, the blind being opened and secured against the wall, as shown in Fig. 1, the fastener-slot o holds against the catch 6. To release the blind, the long arm of the lever G is depressed, as shown in Fig. 4, its short arm drawing the barf upward against the pressure of the spring 16. until freed from the catch. As soon as the lever is released, the spring forces the fastenerbar downward, so that the curved portion .2 of its foot is in position either to engage the catch t' or the loop on the sill, said curved portion riding thereover until said catch or loop enters the respective slot o '0 in a manner which will be readily understood without a more explicit description.
Having thus explained my invention, what I claim is-- The fraine bar d, in combination with the loop g and lugs q secured thereto, the anglebarf, fitted to slide in said loop and provided with the groove 7c, the curved foot .2 on said bar, provided. with the slots 1), the spring 16, interposed between said foot and the framebar, the pin j for engaging said loop, and the lever. C, pivoted in said lugs and having its short arm working in the groove in said bar, substantially as described.
JOHN HANDWERKER.
