* NITED STATES PATENT OFFICE GEORGE D. PAUL, OF NEWARK, NEW JERSEY, ASSIGNOR OF ONE-HALF TO EGBERT ALSDORF, OF SAME PLACE.

FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 379,124, dated March 6, 1888.

Application filed May 28, 1887.

To all whom, it may concern.-

Be it known that I, GEORGE D. PAUL, of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in SashFasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in window-sash fasteners, the object of which is to produce a device of that type which will be reliable in operation, neat in appearance, and of a low initial cost.

l/Vith these objects in view my invention consists in certain features of construction and combinations of parts, that will be hereinafter described, and pointed out in the claims.

Referring to the drawings making apart of this specification, Figure 1 is a plan view of the device complete. Fig. 2 is a plan view of the shell that is placed on the lower sash-rail with thelockinglever removed. Fig. 3 isaside elevation in section of the sash-fastener, taken on the line :0 m, Fig. 1. Figs. 4, 5, and 6 are views of detached parts. Fig. 7 represents a plan view, partly in section, of the sash-fastener in unlocked position. Fig. 8 represents the device in locked adjustment.

A is the shell of the fastener, and A a cor-' responding shell that is placed on the meetingrail of the upper sash, the latter piece having an integrally-formed locking-flange, 0, made to project upward from its top surface. The shell A will be more fully described in connection with other parts of the sash-fastener.

The shell A is of suitable width to be seated and secured on the meeting-rail of the lower sash by screws inserted in the holes a provided for them, similar provision being made for the attachment of the lockingshell A. Both pieces A and A are designed to afford a neat and shapely device that is lightin weight and readily produced by snapflask molding, such as is used in the manufacture of light hardware.

Near the center of the shell A a tapering half-circular wall, I), is made to project from the top surface of the shell. This wall is pro- 5o vided with an integral cap-plate, c, that ex- Serial No. 239,689. (No model.)

tends to produce a complete circular disk. The peripheral edge of the wall b is projected above the top surface of the cap-plate c, and is cut to form two flanged inclines, b b, that start to rise from the surface of the plate 0 at a point, 0', and gradually increase in height to the diametrically-opposite points, I) b", where they abruptly terminate in square shoulders that produce abutments, for a purpose that will be explained.

The lever B, that operates the locking mechanism of the sash-fastener, is provided with an enlarged end rounded to produce a hub, d, which is perforated to receive a vertical shaft, 0. The lower surface of the hub dis cut away 55 to form a transverse rib or hearing at right angles to the extended shank or body of the lever B, and from its shape and location permits a limited rocking vertical movement of this lever upon it'as a fulcrum point or base.

The shank of the lever Bis so shaped that a comparatively thin edge will be produced near the point of contact of the lever with the sloping flanged inclines b b formed on capplate 0, so that the edge of the lever may rest 7 against either of the shoulders I) b when said lever is in aline with the sash-rail upon which the shell of the fastener is secured.

The shaft Cis made cylindrical and of proper diameter to fit looselya hole made in the locking-bar D, which is mounted upon it, this bar having a seat upon the loose base-plate E, which latter is made to conform in contour and height to the exterior surface of the shell A, and is fitted into a notched portion of this shell to form a continuation of the same, this construction of a separate section of the shell A being simply a provision to allow the parts to be readily manufactured, as the design facilitates molding operations.

The shaft C is furnished with an enlarged head, that may be of an acorn shape or any other ornamental form,as may be desired. The body of the shaft has an integral lug, 6, formed on its side, that engages a notch in the per- 5 forated hub of the lever B, to hold the shaft and lever locked together. At a point on the body of the shaft 0 about in line with the shank of the lever B when this shaft and lever are connected, a lug, f, is rc-o made to project, and this lug is so located in regard to the cap-plate c that it will lie immediately below it when the parts of the fastener are connected.

The locking-bar D occupies the space between the top of the loose base-plate E and the lower surface of the cap-plate c. The inner rounded end of the bar D, that is perforated to receive the'shaft G, is excavated on its upper surface, and forms an annular recess, 9, of sufficient depth to admit the lugf and allow it to move between the capplate and the locking-bar. At points ninety degrees distant from each other in the annular recess 9 of the locking-bar D two projecting wings, h i, are formed, that are integral with the peripheral flange Z, beingin effect radial extensions ofthis flange, that from their position engage the lug f of shaft G. The Lugf is placed between the wings, having a bearing contact with the same, when the lever B is made to swing from one position in line with the sash-rail to an opposite location, or through a half-circle.

The shaft 0 is secured in place by a pin, m, which is inserted through a transverse hole made for its reception in the lower end of this shaft, and as the shaft 0 penetrates through a hole made in the base-plate E, which is properly located to receive the same when the parts are assembled and secured as just described, they will be retained intact as an operative device, the lockingshell alone being separable from the other portions of the fastener.

The engagement of the lug f with the wings h z is adapted to move the locking-bar D and cause its upwardly-projecting lug D to have a locking engagement with the flange 0 of the shell A. This lug, hooking under the flange, bears upon its curved rear surface in a manner to draw the rails of the upper and lower sash together when this sash-fastener is in locked adjustment, and it will be seen that such an engagement of parts will take place when the lever is in the position shown in Fig. 8, the unlocked position of parts being displayed in Fig. 7 of the drawings.

The several parts of this sash-fastener are light, and from their peculiar form are capable of being produced by quick processes, so that the device can be manufactured at a low cost; and, further, this novel construction and combination of parts will afford a durable and reliable fastener that cannot be disengaged without a lifting as well as rotative motion applied to its actuating-lever; consequentlyit is as secure in its locking engagement as more costly devices of this character.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. In a sash-fastener, the combination, with a shell having a cap-plate supported integral with it, and inclines that end in square shoulders formed on this cap-plate, of alever located and adapted to rock on the top of the capplate to engage the shoulders of the inclines,

and a lockingbar located below the cap-plate operated by the lever, substantially as set forth.

2. In a sash-fastener, the combination, with a shell having a cap-plate, and a shaft passing vertically through the shell, of a lever connected to said shaft and adapted to rock in a vertical plane thcreon,and a locking-bar seated in the shell and loosely connected to the shaft, the connection between the shaft and lockingbar being such as to permit of a limited rotary motion of the shaft independently of the locking-bar, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE D. PAUL.
