FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 24:8,359, dated October 18, 1881.

(ModeL) T0 atlwhom it may concern Be it known that I, GARY B. SMITH, a citizen of the United States of America, residing at Cleveland, in the county of (luyahoga and State of Ohio, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refere nce being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of sash fasteners or locks for preventing a sash from being opened from the outside.

My invention consists in the novel construction and combination of parts, as will be hereinafter more fully set forth and specifically claimed.

In the annexed drawings, Figure 1 is a perspective view of the sash-fastener applied to the meeting-rails of the sashes. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a side elevation. Fig. 4 is a perspective view of the slotted rail-piece of the upper sash. Fig. 5 is a perspective view of the overlookingpiece of the rail of the lower sash and Fig. 6 is a perspective view of the gravity locking means.

The letter A represents the section of the lock to be attached to the upper surface of the upper or meeting rail of the lower sash. Itis cast inone piece, and is formed with the base portion, a, to rest on the rail, and the upright portion 1), provided with perforated lugs c and c, from the under parts of which extend downward the interlocking arms 01 and d, which form a plane on the outer face, and are inclined from the points to the base on the inner face, forming a half-wedge. The inner face of this section iseut away at the base, and is formed with a vertical recess, 0, extending from the base part way to the top. The arms 0 and 0 have a pivot-hole through them for the purpose ofreceiving the bolt of the locking means, and the base-plate is provided with countersunk screw-holes, so that it may be screwed fast to the rail.

The base-plate may be formed or provided with a finger-lift, substantially as indicated by the dotted lines in the drawings.

The letter B represents the section of the lock to be attached to the lower rail of the upper sash. It is cast in one piece and formed with the horizontal base-plate], to rest on the sash-rail, and the upright g, having the central mortise, h, and the upright exactly fits into the space in section A, between the inner surfaces of the upright and the interlocking arms.

The letter 0 represents the automatic looking plate and hook, formed to fit about the sections A and B when they are .in contact, and is provided on its inner side with a lug, i, and also has a thumb-piece, 7c, substantially as seen inthe drawings. This locking device is secured in place between the arms 0 c of section A by a pivotal bar or rod run through the hole in the base of the thumb-piece. It is also provided with side flanges, l, lapping the wedgeshaped arms and standard portion of the sections.

The object of the downward extending wedge-shaped piece in section A is to fit over the wedge of section B, and thus present them in contact for the action of the automaticlocking hook and clasp, substantially as seen in Fig. l of the drawings.

The device is applied to the sash by screwing section A, with the locking means attached, to the upper rail of the lower sash and section B to the lower rail of the upper sash, so that the standard of the latter will fit and register in the space behind the extending arms of the former, and the lug of the locking means register in the central slot and recess of the sections, falling therein by gravitation when the rails meet with the sashes closed, and thus securely lockin g them together.

To release the sashes from the operation of the lock pressure is applied to the thumbpiece, which draws the lug from the slot and recess, and then the sash may be raised, as in ordinary cases.

It is obvious that slight changes may be made in the construction without departing from the spirit of the invention.

It will be observed that when the rails of the sashes are brought together and the fastener is clasped the rails are so secured that the sashes cannot rattle by the force of the wind,

thus obviating an annoyance not overcome by fasteners usually applied.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In a sash-fastener, the section A, formed with the base a, upright or vertical wall I), with perforated lugs c 0 and interlocking arms (I d. extending from the under side of the lugs, substantially as described.

2. In a sashfastener, the section A, formed with the base a, upright or vertical wall I), with perforated lugs c c, the interlocking arms (1 d, and the vertical recess 0, substantially as described.

3. In a sash-fastener, the gravity lockinghook constructed with the lug i, thumb-piece k, and side flanges, l, substantially as described.

GARY B. SMITH.
