FASTENING FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 234,387, dated November 16, 1880.

Application filed September 16, 1880.

To all whom "it may concern:

Beit knownthat we, CHARLES M. BURGESS, of New Britain, and ROLLIN SANFORD, of Newington, both in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fasteners for Meeting-Rails of Sashes, of which the following is a specification.

Our invention relates to improvements in fasteners for the meeting-rails of sashes in which the sweep bears a flanged post and eccentric bearingzat its inner end and is pivoted in place in a box or case by means of two springs and a sliding bolt; and the objects of I 5 our improvements are to lessen the cost of construction and to afford greater security. We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figures 1 and 2 are plan views; Fig. 3, a vertical section on line a; :r of Fig. 2. Fig. 4 is an under-side view of one part. Fig. 5 is a plan view of one plate. Fig. 6 is a plan view of the sliding bolt, and Fig. 7 is a side eleva- 2 tion of the sweep.

A designates an elevated plate or box designed to be secured to the lower rail of the upper sash. Said box is open or hollow on the under side, and is of sufficient depth to re- 0 ceive springs for bearing upon and holding the sweep in the box, substantially like sashfasteners now in common use. This box differs from prior ones in the fact that it is provided upon its upper side with a transverse 5 recess, a, for the reception of a flat and thin sliding bolt, I). This recess a is of such depth as to extend into the hollow inside of the box and leave an opening through the top of the box, the bolt 1) resting at each end upon the edges or sides of the box, the rear edge being left of such thickness that the rear end of the' bolt 1) will not be carried beyond it when thrown to its extreme forward position. The sliding bolt b is fitted to the recess in the box 4 5 A, and is provided with a circular opening or hole, 0, which fits and receives an eccentric bearing upon the sweep B. The cam-shaped keeper C is the same as those in common use, except that it is recessed upon its upper side (No model.)

for a short distance inward from the straight side, which confronts the box A, for the purpose of receiving the end of the belt I).

The sweep B is cast in any desired design, with the ordinary downwardly-projecting lug d, for engaging the cam-edge of the keeper C. The opposite end of the sweep has the bearing 6 for the bolt, the squared post m, against which the springs n n act, and the flange 0, for taking over the under edges of the spring. The several parts of the sweep may be, and preferably are, cast in one and the same piece, and the bearing 6 is eccentric to the axis of the squared post m.

In order to assemble the parts the flange 0 and post on are passed through the hole 0 in the belt I), and the bearing 6 of the sweep is received in the bolt. The bolt, with the sweep in it, is then placed in the recess a, and the springs 02 n are inserted to hold the whole in place. The bearing on the sweep, which fits the hole in the bolt b, governs the sweep axially, so as to prevent its axis from moving either to the right or left, while its axial position, from front to rear, is governed entirely by the squared post m and springs n a. Small lugs s are cast upon the under side of the bolt 1) to limit the extent of its forward movement.

In Fig. 1 the parts are represented with the sweep thrown to the right and the sash unlocked, while in Figs. 2 and 3 they are represented with the sweep brought to the front and the sash locked. Moving the sweep from either side to the front to draw the sash-rails together also operates to throw the bolt outward, with its front end over the keeper, as shown in Figs. Zand 3, when the bolt performs the double function of firmly locking the sash and of cutting off all access to the sweep by means of a knife-blade or other thin instrument inserted between the sash-rails from the outside. I i y We are aware that sweeps in prior sashfasteners have been provided with a flanged post, and were held in place by a spring or springs within a box or case which bore upon the square of the flanged post; also, that a prior patent shows a sash-fastener having a sweep pivoted within a box upon a fixed axis and with a slotted and sliding bolt under the and flanged post m at its inner end, the springs 10 sweep at the base of the box, which bolt was it n, bolt 1), box A, and keeper 0, substantially thrown forward over the keeper by means of as described, and for the purpose specified.
