FASTENER FOR THE MEETING-RAILS` OF SASHES.

Y SPECIFICATION formingl part of Letters Patent No. 453,339, dated J' une 2, 1891. Application filed October 25, 1890- Serial No. 369,357. (No model.)

'To au whom, t may concern:

This invention relatesto certain new andv useful improvements in fasteners for the meeting-rails of sashes, but ismore particularly designed as an improvement in the class of locks shown and described in Letters Patent of the United States No. 403,102, granted to `me the 14th day of May, 1839.

The object of my present improvement is to furnish a fastener operating upon the same general principle -as that exhibited in the Letters Patent aforesaid, and which While of great strength and utility shall be simple and cheap in its construction; and with these ends in view my invention consists in the combination of elements and co-operating parts, hereinafter fully described, and then recited in the claims.

In order that those skilled in the art to which my. invention appertains may fully understand the construction and operation of my improved fastener, I will describe the same in detail, reference being had to the accompanying drawings, which form a part of this specication, and in which- Figure 1 is a vertical longitudinal section taken centrally through the fastener at the line y of Fig. 4, the sashes being shown as locked; Fig. 2, a similar view, but showing the sashes as unlocked and the post partially Withdrawn Fig. 3, a plan view with the housand lower sash-rails. Upon the upper surface of the sash-rail A is the post, which forms one element of the complete fastening device. This consists of the base 1, bearing the vertically-.projecting portion 2, these parts being preferably made of strong sheet metal drawn and bent into the proper shape. outside, near the base, the post 2 is provided with a flange 3, whose purpose will be presently explained.

4 is a housing, whose general shape in section appearsat Figs. 1 and 4. This housing or shell maybe either castor drawn from sheet metal, as may be found convenient.

5 is a base-plate, which is adapted to fit within the bottom of the housing, asseen at Figs. 1 and 4. At its ends it is provided with perforations 6,'Whioh fit over a pair of downwardly-projecting hubs 7, which depend from the ends of the housing, and through which screws 8 are adapted to be driven for the purpose of securing the housing in position upon the sash-rail. The housing and plate are securedtogether by placing the latter over the hubs, as just recited, and then swaging the ends' of said hubs outward after the manner of an eyelet, as appears at Figs. 4 and 8. This, as will be readily seen, does away with the use of any rivets or screws in the construction and assembly of the several parts. At the center of the base-plate is formed integral therewith an upwardproj ection 9, (see Figs. 1, 3, and 4,) whose outer face is inclined, as seen at 10, said incline being provided with raised flanges 11 at either side thereof, as appears from the drawings. In front of the base of this projection is an outwardly-projecting lip 12,extending along the edge of the base-plate, and which is adapted -to co-operate with the flange or lip 3 upon the locking-post, for a purpose which will presently appear.

At either side of the projection 9 is formed a small wedge-shaped fulcrum 13, which is preferably cast integral with the base-plate. They are shown in front elevation at Fig. 4.

14 is the operating-lever which has a central opening 15, adapted to slip easily over the part 9, and at either side of said opening said lever is bent, as at 16, to form seats adapted to rest and turn upon the fulcrums just described. The front end of this lever is pro- Upon the vided with a pair of lingers 17, turned upward substantially at right angles.

18 is a eylindric roll, which, when in position, serves as the movable locking element of the fastener.

19 is a spring arranged within the housing and engaging the roll with a downward pressure.

2O is a button, which projects upward through the rear end of the housing and whose lower end engages and is adapted to operate the rear end of the lever 14.

In assembling my improved sash-fastenin g device the lever is first placed in its position over the central projection, (see Fig. 3,) so that it is balanced upon the fulcrum-point heretofore referred to. The roll 18 is then set in position upon the forward end of the lever between the fingers 17, the periphery of said roll resting against the inclined surface 10 of the projection. Then in this position, it is held as against lateral displacement by the ngerson the lever and the flanges 11 at the sides of the inclined surface. When these parts are in this position, the housing, into which spring 10 has been inserted and likewise the button 20, is placed over the baseplate, and the whole secured by expanding the ends of the hubs upon t-he housing, as shown at Figs. 4 and 8.

In the operation of my invention the two members which form the complete fastener are disposed upon the meeting-rails of the sashes, so that when the latter are in their closed position the post 2 may enter between the front wall of the housing and the periphery of the roll 18. In closing the sashes the post as it enters will in its passage between the housing and the roll lift the latter against the downward pressure of the spring, at the same time pressing it a little upward and backward along its inclined seat. Upon attempting to withdraw the post, however, it

will be readily understood that the roll will wedge said post fast against the outside of the housing, in the same manner as the construction shown and described in the Letters Patent heretofore referred to. lVhen the parts are locked and it is desired to release them,pressure upon the button at the rear of the housing, will tilt the lever on its fulcrum, and thereby raise the` roll 18 upward and slightly backward against the thrust of its spring, thereby removing it out of contact with the surface of the post, which may then be withdrawn. The two overlapping flanges or lips 3 and 12, heretofore referred to, are designed to prevent the introduction between the sashes of any thin instrument by means of which the roll might be lifted so as to cease to bind the post.

I claim 1. In asash-fastener, the combination,with the base plate having perforations therethrough, ot' the housing provided with depending hubs adapted to extend through said perforations in the base-plate, said plate and housing adapted to be secured together in assembled position by the expansion of the hubs within said perforations, substantially as described.

2. In a sash-fastener, the combination, with the locking-post, of the complementary portion of the fastener, the same consisting of the base-plate bearing the inclined faced projection, the lever arranged astride said projeetion and fulcrumed at its center, the roll seated upon the lever and adapted to be actuated thereby, and the inclosing housing secured to the base-plate and provided'with means for the operation of the lever, substantially as described.

3. In a sash-fastener, the combination, with the post, of the base-plate provided with a projection, the lever astride said projection and having a seat for the roll, the inclosing housing secured to the base-plate, and a button projecting through the housing and adapted to operate the rear end of the lever, substantially as described.

In testimony whereof Iaiiix mysignature in presence of two witnesses.

GEORGE M. GRISWOLD.
