MARTHA A. BROWN, OF PITTSBURGH, PENNSYLVANIA.

SASH-FASTENER.

Specification of Letters Patent.

Patented June 28, 1921.

Application filed October 16, 1919. Serial No. 331,228.

consists of a device to be applied to windows to prevent rattling of same and to lock same to prevent their being opened by intruders.

Other objects of my invention are to secure a window fastening having no free play in its parts, minus springs or small parts likely to rust and breakage, and which, when used as a positive lock will be inoperative from the window exterior by the usual devices of burglars. I also wish to provide a lock in which any force used in opening the window improperly will not be resisted by attaching screws but by the resistance to shear of the lock members.

While my device may be applied to swinging windows and to various parts of windows, I have illustrated it as applied to the meeting rails of two window sashes of the ordinary type and in the drawings Figure 1 is an elevation of such a window with my device seen in the center of the top rail of the lower sash; Fig. 2 is an enlarged vertical section on line 2-=-2 of Fig. 1; Figs. 3, 4 and 5 are perspective details of the parts of my device and Fig. 6 is a modification of my invention as applied to a metal sash.

My lock in it preferred form comprises an elongated tubular socket 1, a barrel 2 and a locking pin 3. The open end of socket 1 has a flange 4 provided with holes for attaching screws. Barrel 2 extends entirely through one sash-frame, is open at its inner end, threaded throughout most of its length, and at its outer end has a flange 5 also provided with holes for attaching screws. Lockingpin'3 has a relatively small diameter shank 6, a socket engaging end 7 and an intermediate threaded portion 8 which fits in barrel 2 to form a locking-head. After locking pin 3 is assembled with barrel 2, a knurled knob 9 is pinned to the end of shank 6 and by this knob the lockingpin is screwed. back and forth so as to engage or disengage socket 1. I have shown socket 1 and pin end 7 slightly tapered to facilitate insertion of the latter.

Barrel 2 is choked at its flanged end to prevent pin 3 from being screwed out of the barrel or from being screwed in so far as ,to force the sash rails apart an undue amdunt.

To apply the device to a window, it is only necessary to bore and counterbore the holes in adjacent rails, insert socket 1 and barrel 2, with the locking pin assembled therewith, and drive in the holding screws.

It will be apparent that the insertion of a thin tool between the window rails from the outside will not enable an intruder to unlock the device because the only way to operate same is to turn the locking pin which may only be done by firmly grasping knob 9 and twisting it. If any attempt is made to force the sashes apart without unlocking the device all of the strain comes on the locking-head of pin 3 .and not on the light screws used for attaching the device. As the elongated locking-head extends across the .joint between the sash-frames and in close contact with the socket and barrel for a considerable distance on each side of the joint, it forms a lock which cannot be sprung out of locking position or made inoperative by being bent through the application of force applied to the sash-frame.

In the modification shown in Fig. 6 the socket and barrel are integral with the steel sash and both are threaded and pin 10 is threaded along the socket engaging portion which is not reduced as in the preferred design. A plug 11 is inserted in the threaded passage in the barrel rail and serves the purpose of the choked lend of barrel 3..

lug 11 may be adjusted to regulate the inward and outward movement of the locking Besides the advantages previously pointed out, it will be noted that the ledge formed by the sash rail to which the lock is applied, is free from the projection which is present in the usual type of Window fastener and which is not only unsightly but interferes with cleaning the ledge as an inspection of the top of any window so equipped will demonstrate.

I claim l j 1. A sash-fastener comprising a lockingpin constructed to extend through one of the sash-frames and provided with an elongated locking-head and exterior screwthreads and adapted to lie across and extend a considerable distance on each side of the joint between two sash-frames when in locking position, and a metallic inclosing member for said pin located in each of the sash-frames, both of said inclosing-members closely contacting with said locking-head at the joint-line between the sasheswhen in its locking position, one of said inclosing-members extending entirely through its respective sash-frame and screw-threaded interiorly substantially its whole length to engage the screw-threads on the locking-pin whether in its locked or unlocked position.

2. A sash-fastener comprising a, lockingpin constructed to extend through one of the sash-frames and provided with an elongated head formed smooth and slightly tapered at its free end and screw-threaded for the balance of its length, said lockinghead adapted to lie across and extend a considerable distance on each side of the joint between two sash-frames, a socket-member embedded in one of the sash-frames and adapted to receive the smooth slightly-tapered end of the locking-head and a barrel embedded in the other sash-frame and internally screw-threaded substantially its whole length to engage the threads on the locking-head, said socket-member and barrel each closely contacting with said locking-head at the joint-line between the sashes when in looking position.

In testimony whereof, I have hereunto subscribed my hand this 1 1 day of October, 1919.
