W-QE. SPARKS} Improvement in Fasteners fer the Meeting Rails of Sashes.
Patented March 12, 1872.
Bylaw a4 55% 4 WILLIAM E. SPARKS, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO SARGENT & CO., OF SAME PLACE.
IMPROVEMENT IN FASTENERS FOR THE MEETING-RAILS OF SASHES.
Specification forming part of Letters Patent No. 194,515, dated March 12, 1872.
To all whom it may concern:
Be it known that 1, WILLIAM E. SPARKS, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents, in-
Figure 1, a front View; Fig. 2, a side view; Fig. 3, a top view; and in Fig. 4, an underside view of the lever-plate.
This invention relates to an improvement in the construction of the class of sash-fasteners known as levers or turn-buttons, such as are applied to the meeting-rails of the sash; and the invention consists in the arrangement of the lever upon the upper side of a chambered plate, having an arm within the said chamber, to which a spiral or similar spring is applied, the tendency of which is to hold the lever when turned to fasten the sash, or to throw it completely back when it is desirable to open the sash.
A is the lever-plate, which is chambered beneath, as seen in Fig. 4. Upon this the lever B is pivoted and to the pivot of the said lever, within the chamber, an arm, C, is attached so as to turn with the lever, the pivot being at a. Upon the arm C a projection, d, or other means of securing a spiral or similar spring, F, is formed; and the other end of this spring is fixed at a point, f, in the rear of a central line drawn from the point at through the pivot, as denoted in broken lines, Fig. 4. Hence, when the lever is turned forward to lock the sash, as in .Fig. 4., the tendency of the spring is to hold the lever in that position; but when the lever is turned toward the pdsition denoted in broken lines, Fig. 4, to the extent to bring the point d forward of the pivot, the spring will then tend to throw the lever to the other extreme, as denoted in broken lines, Figs. 3 and 4; hence, as the greatest power of the spring is at the extreme throw of the lever, it insures the lever being turned to the proper position to avoid contact with the lower sash when moved to open the window. This is an advantage over the common arrangement of springs, in which the action is weakest at the extreme of the throw. The keeper D is formed corresponding to the plate A, to receive the end or nose of the lever to secure the sash together.
