/m Y o h a C., saluted W ew WILLIAM" PHELPS' Jn., or
SALEM,A MASSACHUSETTS.
Letters Patent No. 83,7 89, dated November 3, 1868.
IMPR'OVEME NT IN BLIND-FASTENERS.
To all whmn tt'may concern Be it knownthat I, WILLIAM PnELPs, Jr., of Salem, in the county of Essex, and State of Massachusetts, have invented an Improved Blind-Fastener; and I do hereby declare the following to be a full and correct description of the saine, reference being had to the accompanying drawings, in which- Figure l is a perspective view ofthe lower part of'a window-frame and blind having my improved fastener attached;
Figure 2 is a view of the fastener in position, the wood-work being partially removed to show the'rela- `tions of all the parts;
Figure 3 is a to'p view ofthe latch-plate;
Figure 4 is a top view of the confningplate, which holds the latch-plate in position; and Figure 5 is a bottoni view of the saine.
The same letter marks the same part wherever it occurs.
The nature ofthe invention consists in the peculiar construction of the latch-plate, and in theidevices for confining and operating the Sallie, the whole forming a new and improved blind-fastener, as hereinafter more fully set forth.
In the accompanying drawings, A marks Aa windowsill, forming part ofthe flame of an ordinary window; B, the lower bar of the frame of the blind, to the under .side of which the fastener is attached.
C marks the window-fiam'e,and D the blind-hinges.
E is the latch-plate, shown in perspective in g. 2, .and in plan in tig. '3.
In this plate are four notches, b b and c c, of which the two, b b, alternately catch upon a pin driven into the window-sill when the blind is closed, and upon a staple in the outer wall when the blind is opened.
The notches o c receive the points afa of the contining-plate F, which alternately serve as fulora for the latch-plate E.
A hole, d, receives the free end of spring s, the reaction of which tends to hold the plate E in contact with the plate F, in the position shown in iig. 2.
A stud, e, serves as a handle to operate the latchplate.
F is the confining-plate or socket, by which the plate AE is held in place. It is shown intop view in g. 4, and in bottom view in fig. 5, and in perspective, as -attached to the'blind, in figs. l and 2. It is fastened to the bottom of the lower bai` of the blind-frame by screws passing through holes t' '13.
The peculiar feature oi' this plate consists in the points a a, which enter the notches c c of plate E, and serve alternatelyr as fulcia for that plate.
A semicircular recess, in one end of the slot in pla-te F, reeeivesa corresponding projection of plate E, and the two are'held in Contact by the spring s.
The form and position of this spring, and the recess in which it lies, are clearly shown in iig. 2. Its free end enters a hole, d, in plate E.
' The operation is as follows:
When the blind isV closed, the inner hook of the latch-plate catches upon the pin f, in the window-sill,
-in the usual way. It is released by drawing back the end of the plate by means of the stud e, when the point a, farthest from 0, becomes the fulerum upon which the latch-plate turns. The other point, a', be-
comes thefiller-uni when the outer hook of plate E engages with the staple in the wall, arranged to receive it. rI he spring s gives the required impulse to the :itch-plate, by whichever end it may be operated.
The advantage of Ythis invention lies in its simplicity. The fastener consists of but three simple parts, inexpensive, easily made, readily applied, and little liable to get out of order.
Hating thus fully described my invention,
What I claim, and desire to seciue by Letters Patent, is-V The combination and arrangement of the plates E and F with the spring s, all constructed and applied substantially in the manner and for the purpose specified. y
The above specification of my said invention signed and witnessed, at Salem, this 3d day of J une, A. D; 1868. W'M. PHELPS, J R.
Witnesses:
GEORGE HoLMAN, CHARLES PrneLrs.
