W'ILLIAM E. SPARKS, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO SAR GENT & COMPANY, OF SAME PLACE.

IMPROVEMENT IN FASTENERS FOR MEETING-RAILS OFSASHES.

Specification forming part of Letters Patent No. 126,754, dated May 14, 1872.

To all whom it may concern:

Be it known that I, WILLIAM E.-SPARKS, of New Haven, in the county of New Haven and State of Connnecticut, 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, an end view Fig. 2, a top view of the same; Fig. 3, an underside view of the same looking up; and in Figs. 4, 5, and 6, de-

tached parts to illustrate the construction.

This invention relates to an improvement in that class of sash-fasteners which are arranged upon the meeting-rails of window-sashes to secure the upper and lower sash in their closed position, the object being a construction which will require little more labor than the process of casting,.thereby producing a very cheap but good fastener; and the invention consists in a chambered base having an opening directly through top for the insertion and bearing of the lever, combined with the lever, constructed with a downward-proj ectin g stud with one ormorelateral projections therefronnwhich, when set into the said base or plate -the opening formed with notches for the admission of the said projections--the said stud taking its bearing in the said opening and turned to its working position-the said projections pass beneath the said plate and thus secure the lever to the plate; and coinbi nedwith a spring, which, bearing against the flat side of the said stud, retains it in the position indicated by such flat side, either as locking or loosening the sash.

A is the plate or base, which is chambered (see Figs. 4 and 6,) the diameter of the stud at the base corresponding to the opening B in the plate, forms a bearing upon which the lever may be turned. On this stud, and below the base a distance equal to the thickness of the plate, I form two projections, a b, in position corresponding to the two notches a I) in the plate, when the said lever is at some point out of its natural path-that is, substantially as seen in Figs. 4: and 5-the lever turned back for insertion. The projections pass freely through the notches, and the leversets into its bearing in the plate, and is then turned to the position seen in Fig. 3, the projections passing beneath the plate prevent the removal of the lever. In that position the spring F is inserted, two sides of the lever being flattened, as seen in Figs 3 and 4, for the bearing of the spring. The spring is supported at either end and the lever is held in either position by the said spring yielding for the turning of the lever to the right, which, when so turned, is held in that position by the spring, as denoted in broken lines, Fig. 3. The projections to I) serve also to prevent the turning of the lever too far-that is to say, the projection a prevents the turning of the lever to the left and the projection b prevents turning too far to the right, whereby the accidental removal of the lever is avoided. To more perfectly provide against such accidental removal Iform a stop, n, upon the inside of the case, back of the spring, to prevent the depression of the spring by the said projections should they be turned into contact. I also form another projection, t,'on the opposite side of the case, against which the projection a strikes when thrown out, as seen in Fig. 3.

While two projections and corresponding notches are preferable, one notch and projection may alone accomplish the object, but not so perfectly as two or more. The keeper may be any of the known constructions.

I claim as my invention- 1. A sashfastener, consisting of the plate A and lever C, when the said plate A is constructed with anopenin g, B, and one or more notches,

a b, in the said opening, and the said lever, with a stud, D, provided with projections corre sponding to the said opening and notches in 3. In combination with the subject-matter of the said plate, the said projection or projecthe second clause of claim, I claim the stops at tions to pass beneath the said plate when the t, one or both, beneath the plate, substantially lever is set into position substantially as deas and for the purpose specified.

2. In combination with the subj ect-mattei' of the first clause of claim, I claim the spring I, Witnesses:

the stud D being constructed to take a bearing G. W. BURDETT, on the said spring, in the manner described. CHAS. L. BALDWIN.
