SPECIFIGATION forming part of Letters Patent No. 731,317, dated June 16, 1903. Application filed September 16 1902. Serial No. 123,646. (No model.)

To allwhoml it may concern:

Be it known that 1, JOHN D. MILLER, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Sash- Lock, of which the following is a specification.

This invention is an improvement in sashlocks or fasteners. Its object is the production of a simple device easily applied and operated whereby two sashes in a windowframe may be controlled by a single means; and it consists in certain new and useful features of construction and in the combination of the parts, as hereinafter shown, described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a transverse horizontal section through a window frame and sashes at the meeting-rails. Fig. 2 is a view showinga portion of the sashes in elevation and a portion of the frame, sash, and lock in vertical section. Fig. 3 is a plan view of the device, the top plate or retaining-cover having been removed. Fig. 4 is a perspective view of the underside of said retaining-cover; and Fig. 5 is an elevation of the device along the plane indicated by the line V V in Fig. 2, the casing being shown in section and the interior mechanism in transverse elevation.

This sash-lock may be applied wherever two sliding sashes serve to close a window-frame. It is adapted for location opposite the sash meeting-rails, and by its use both the sashes may be locked or supported by one device and only oneof them released at a time.

In the drawings, indicates a portion of one side of a window-frame; 11, the upper sash; 12, the lower sash; 13, the outside bead; 14, the parting-bead; 15, the inside bead, and 16 a portion of the casing of an ordinary window.

Inserted in a suitable cavity in the frame 10, opposite the..meeting-rails of the sashes, is a rectangular metal casing 17, having a detachable cover 18, which is secured in place in any suitable manner, as by a screw 19 engaging a'socket 20 in the bottom of the casing.

Yieldably supported in the casing 17 and passing through the cover 18 are bolts 21 22, adapted to respectively engage spaced cavities in the adjacent edges of the sash 11 12.

These bolts 21 22 are provided, respectively, with springs 23 24., by which they are maintained normally in engagement with the sash and adapted to be withdrawn into the casing 17 when the sash is to be released. The sashes 11 and 12 are provided with spaced recesses 25 26, adapted for engagement with the bolts 21 22, said recesses being plainly seen in Fig. 2 of the drawings. Longitudinally disposed centrally through the casing is an operatingrod 27, extending outward at one end through the frame 10 and casing 16 and provided with a knob 28 upon its outer end, by which means the rod may be operated from inside the room.

The casing 17 is provided with a transverse partition composed of webs or fins 29 and 30, rising from the bottom and depending from the cover of said casing. One end of the easing is likewise formed by a flange 29, rising from the bottom of the casing, and a web 30, depending from the cover. This end and the transverse partition are provided with bearings for the rod 27, which has a longitudinally-slidable and also a rotary movement in said bearings. A spring 32 is coiled. upon the rod 27 between the partition 29 30 and an arm 36, extending laterally from said rod,

which is thereby forced in an outward direction, and the arm 36 by engaging the bolt 22 limits the outward movement of said rod. The bolt 22 is provided with a laterally-extending arm 34, upon which the pin 36 of the rod normally rests. The rod 27is provided at its inner end with a laterally-extending pin 37, adapted to engage an arm 33, extending laterally from the bolt 21.

It will be seen that when the rod 27 is in its normal position it may be partly rotated,with the effect of depressing or withdrawing from engagement with the recesses 26 in the lower sash the bolt 22, thus permitting said sash to be manipulated. Similarly, by pressing the rod 27 inward against the tension of the spring 32 a partial rotation will cause the pin 37 to engage the arm 33 of the bolt 21, with the effect of withdrawing thelatter from engagement with the upper sash, which may thus be manipulated at will. A cam 35 is formed in the bottom of the casing, which by engaging the pin 36 guides the latter to its normal position in engagement with the arm 34 when released from the pressure pushing it against the tension of the spring 32.

The device may be readily adapted to the different sizes of sash and may be modified in minor particulars without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described myinvention, what I claim is- A sash-fastener comprising a casing, a pair of independent spring-actuated bolts, a slidable and rotatable shaft carrying independent means for independently operating said bolts, spring means for forcing said operat- I5 ing-shaft in an outward direction, and means for guiding the operating means for the outer bolt automatically into normal engagement with the latter.

In testimony that I claim the foregoing as 20 my own I have hereto afiixed my signature in the presence of two Witnesses.

JOHN D. MILLER.
