BENJAMIN D. WA SHBURN, OF BOSTON. MASSACHUSETTS.
Letters Patent No. 84,032, dated November 10, 1868.
IMPROVEMENT IN SHUTTER-FASTENER The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, BENJAMIN D. WASHBURN, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Improvement in Blind-Fasteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this spoofication, in which- Figure 1 represents a side view of a fastener embodying my improvement.
Figure 2 is a front view of the same.
Figures 3, 4, and 5 are views of a modification of my invention.
The object of my invention is to produce a fastening for blinds or shutters, which will insure the same being caught and held in position as it passes into the catch when the blind or shutter is opened or closed;
' and the invention. consists of an elongated tooth or projection, formed centrally between the jaws of a fastening in common use, so that when one of the jaws passes over or into the catch, the said elongated tooth or projection will prevent the fastening from slipping entirely over the catch, and thus fail of being properly secured.
Referring to the drawings, A represents a fastening, designed to be-secured to a spring, which is attached to the button of a blind or shutter, as shown in fig. 1.
It is formed with two jaws, c a, between which is a projection, 11, extending below the jaws to a, so that, as the said blind or shutter is closed or opened, the portion a of the fastening will enter the catch, and be prevented from passing beyond or over the same by the projection b striking against the end of the catch.
It frequently happens that the fastening, as usually made with a single opening or recess, when the blind is thrown open or closed, will pass entirely across the catch, without taking into the-same, and it then becomes necessary to adjust the fastening properly by moving or manipulating the spring which holds the catch.
By my improvement, this difficulty is entirely obviated, as the jaw that enters the catch will be stopped at the point when it will, of necessity, be forced in by the spring, the elongated projection 11 preventing it from passing over or beyond the opening.
Fig. 3 represents a modification of my invention, the fastening A consisting of an arm supported in a frame, B, which is secured to the blind, and provided with the elongation 1), between the jaws a a. The said catch operates by its own weight, instead of a spring, in passing into the catch.
I am well aware that a device similar to mine has been patented by Albert Bingham, June 25, 1867. I claim my invention only as an improvement on his.
What I claim as my invention, and desire to secure by Letters Patent, is-
The construction and arrangement of the piece A with the projections c a and b, the latter extending below the former, when formed in one piece, as and for the purposes herein set forth.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
B. D. WASHBURN.
