SASH-FASTEN ER.

SPECIFICATION forming part Of Letters Patent NO. 426,303, dated April 22, 1890.

Application led December 4:, 1889. Serial No. 332,549. (No model.)

T0 all whom. it may concern:

Be it known that I, FRANCIS P. MeGovERN, a citizen of the United States, residing at Conshohocken, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Improvement in Sash-Fasteners, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in a sash-fastener adapted to lock upper and lower sashes to each other and to the windowframe, as will be hereinafter fully set forth and definitely claimed.

Figure l represents a perspective view of a sash-fastener embodying my invention. Figs. 2 and 3 represent longitudinal sect-ions of portions thereof. Figs. 4t and 5 represent sections on lines, respectively, 'y y and o; o3, Fig. 2, on an enlarged scale.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A and B represent two boxes, which are connected by a plate C, so that they extend at a right angle to cach other, the box A being located on the top of the meeting-rail of the lower sash, and the box B the front thereof, said boxes being iirmly secured to the meeting-rail and each containing a bolt, the bolt D of the upper box being adapted to engage with a perforated or recessed plate E, secured to the side rail of the upper sash, and the bolt F of the lower box being adapted to engage with a perforated or recessed plate G, secured to the side stile or rail of the window-frame, it being noticed that the bolt D locks the two sashes to each other, and the bolt F locks said sashesto the window-frame, thus doubly fastening the sash.

In Fig. 1 the bolt D is shown with a knob, and in Fig. 2 with a hook, either adapted to withdraw the bolt, when so required, without, however, effecting the operation of the device.

The upper bolt is held in engagement with the plate E by means of a spring H, which bears against one end of the box A, and a shoulder J at the back of the head of the bolt.

A portion of the bolt F is screw-threaded, as at K, and the corresponding portion of the interior of the box B, through which said bolt passes, is also threaded, whereby the bolt may be advanced and returned by rotating the same, and said bolt cannot be shot back by an implement inserted between the box B and plate G.

The box A has portions of its upper part and ends separated from the remaining parts, forming a cap L and tongues M, the latter being at the ends of the cap and of dovetailed form to fit or engage dovetail grooves N in the end walls of the box, said cap and tongues being readily removable from the contiguous parts of the box by motions in the longitudinal direction thereof. It will be seen that primarily the cap may be slid out at the nose end of the box, thus uncovering the top of said box, and likewise the ends thereof, owing to the connection of the tongues M with said cap. The spring ll and bolt D may now be inserted in position in the box, after which the cap and tongues are restored, thus clos# ing the top and ends of the box and retaining the bolt and spring in position, it being noticed that the under portion of the tongues and front end of the upper portion of the contiguous wall are recessed to receive the adjacent portion of the bolt and permit the movements of the latter, it being also noticed that the spring occupies a recessed or reduced portion of the bolt D, thus decreasing the thickness of the box A.

The dovetailed tongues M are held tightly in the dovetailed grooves N, whereby displacement of the cap is prevented; but they may be forcibly driven from their position,where by access may be had to the bolt and spring when so required. l

It is evident that the 'screw-bolt F may be held disengaged from the plate G by properly rotating the same, the spring-pressed bolt D then being employed for ordinarily fastening the two sashes; but at night, or when the room is unoccupied, the bolt F is properly 10- tated, so that the two sashes as fastened by the bolt D may be said to be screwed to the window-frame, thus rendering the fastening doubly reliable in its action.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A sash-fastener consisting of two bolts and boxes therefor, saidboxes being connected at an angle, whereby one box occupies the top of a meeting-rail and the other box occupies the front thereof, substantially as described.

2. A sash-fastener consisting` of two boxes at an angle to each other and at different ele- 5 vations, one box containing a spring-pressed bolt and the other box containing @screwbolt, said bolts engaging with plates, respectively, on the sash and frame, substantially as described. Y

3. In L Windmwfatstener, t bolt, a; box con- Io taining the sinne having a dovetail groove therein, and a' removable cap having inclined sides to t said groove, substantially as described.
