BLIND FASTENING Patented July 30; 1895.
UNITED STATES MAW, has.
PATENT O FICE. 7
LOUIS W. JORDAN, OF BOSTON, MASSAOHUSETTSQ BLIND-FASTENING.
SPECIFICATION forming part of Letters Patent No. 543,808, dated July so, 1895.
Application filed June 13, 1895.
To on whom it may concern:
Be it known that I, LOUIS W. JORDAN, a
citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Blind-Fastenings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,making part of this specification,in which- Figure 1 is a perspective view of my improved fastening applied to a window-blind. Fig. 2 is an enlarged transverse vertical section of the same. Fig. 3v is a perspective view of the fastening removed from the blind.
My invention has for its object to provide a strong, simple, and inexpensive blind-fastening which can always be relied upon to engage with its catch or keeper when opened or closed, and which will be free from liability to become accidentally disengaged therefrom, and will support the blind when open or shut and prevent it from sagging by its own weight; and to this end my invention consists in a blind-fastening constructed in the manner hereinafter described and claimed. I
In the said drawings, A represents a window-blind, and B the sill of the window to which it is applied. To the under side of the bottom rail of the blind A is secured, by means of screws a, my improved fastening, which consists of a metal plate 0, having two oppositely disposed depending side flanges or members b h, each of which is provided with a slot d, open at one end for the reception of the straight bar eof the staple or eye D which forms a keeper for the fastening O, the slot of the flange b engaging the eye or keeper projecting from the side of the building, and the slot of the flange b engaging the staple or keeper projecting from the window-sill. These slots are arranged reversely with respect to each other, so that the open end of each one will be brought opposite to the bar 6 of its respective keeper when the blind is opened or closed.
At the inner end of each of the slots 01 is formed an upwardly-extending notch or offset f, into which the bar 6 of the staple or eye D fits as soon as it reaches the end of the slot,
whereby the fastening is locked in place and held securely by the weight of the blind until the latter is raised sufficiently to disengage the bar e from the notch f, when it will be Serial No. 552,709. (No model.)
free to pass out of the slot (1 as the blind is swung on its hinges. It will be seen that the lower portion 10 of each of the flanges b b, which extends some distance beyond the notch f, forms a guard to prevent the blind from being lifted off its hinges while being raised to disengage the notch f from the bar e of the eye or staple D, as said bar will then contact with the portion 10, and thus only permit the blind to be raised sufficiently to allow the bar e to pass out of the slot as the blind is 65 opened or closed. The space between the side flanges b b is sufficient to permit considerable play or loose motion of the blind on its hinges and yet insure the engagement of each flange with its receptive eye or staple.
The above-described fastening may be applied to any blind already in use, and will always be found reliable and free from liability to break or get out of order.
What I claim as my invention, and desire to secure byLetters Patent, is-
1. The herein described blind-fastening consisting of a plate adapted to be secured to the bottom of the blind, said plate having depending side-flanges or members each provided with a slot open at one end and having an upwardly extending notch or offset at its inner end, said slots being arranged reversely with respect to each other and adapted to engage respectively the keeper on the window sill, and that on the side of the building,substantially as described.
2. In a blind-fastening, the plate O, having oppositely disposed depending side flanges b, b, each provided with a slot d, open at one end and having an upwardly extending notch or ofisetfi at its inner end, said slots being arranged reversely with respect to each other, and each flange having a portion 10, extending beyond the notchf, and forming a guard to limit the upward movement of the blind in releasing the fastening, in combination with keepers each provided with a bar 6, adapted to enter one of said slots and engage the notch or offset f, of the same, substan- Ico tially as described.
Witness my hand this 8th day of June, A.
