SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 432,639, dated July 22, 1890.

Application filed May 15, 1890. Serial No. 351,882. (No model.)

To aZZ whom it may concern.-

Be it known that I, THEODORE NEWTON, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to the class of devices that are secured to a window-sash for the purpose of fastening the same; and the objcct of my invention is to provide a simple but efficient device, by means of which the two sashes may be fastened together, so that a space may be left either at the top or bottom of the window for ventilation an d yet hold the two parts of the sash firmly together in such manner that they cannot be opened to any greater or less extent without releasing the fastening.

My invention consists in details of the several parts making up the fastening device as a whole,'and in their combination, as more particularlyhereinafter described, and pointed out in the claims.

Referring to the drawings, Figure 1 is a view in front elevation of awind'ow, showing two sashes fastened open by my improved device. Fig. 2 is a detail front View, on an enlarged scale,of the siderails of two sashes. Fig. 3 is a detail top View, on an enlarged scale, in cross-section through one sash and through the bolt-case of'the fastener.

In the accompanying drawings, the letter a denotes a Window-frame; l), the upper sash; c, the lower sash having the meeting-rails I) 0, respectively.

The fastener D consists of a bolt-case (Z, within which a sliding and rotary bolt e is supported. This bolt-case is adapted to be fastened on the top of the ineetingrail 0', so that the locking end e of the bolt 6 projects into a recess formed in the side rail b of the upper sash. In a socket in the upper sash a catch-plate fipreferably formed of metal and having a lengthwise slot f, is secured. On one or both sides of the slot, preferably on both, and within the socket are locking-recesses into which the T-shaped fastening end of the bolt e is adapted to fit. The slot is of such width with relation to this fastening end that the latter may be readily pushed through the slot when it is in an upright position; but when the bolt is rotated .a quarter-turn the locking end of the bolt will, when slid forward, engage the recessesin the catchplate. A spring g is located within the boltcase (Z with one end thrust against a shoulder on such case and the other thrusting against a pin or shoulder on the bolt in such manner as to cause the bolt to be normally held against forward sliding movementin the case, the tension of the spring operating to draw the two sashes together when the looking end of the bolt is engaged with the catchplate on the opposite sash. The bolteis provided with a handle 6 located conveniently of access outside the case, and by means of it the bolt may be engaged with or disengaged from the locking-recesses in the catchplate. By grasping the handle 6 and pushing toward the sash the bolt is slid forward until its end enters the recess in the opposite sash, passing through the slot f, and the bolt is guided in this movement by a pin 2, that projects from the bolt and travels in a lengthwise slot in the case.' A branch slot from the first allows the bolt to be turned a quarter-turn, so as to throw the locking end transversely across the slot and adapt the projecting ends to engage the sockets in the back part of the catch-plate as soon as .the pressure upon the bolt is removed, so as to allow the spring to thrust the bolt backward, as it will do as soon as the pressure upon the bolt is removed.

I do not limit myself to the particular construction of the bolt-case and engaging parts of the bolt end and socket-plate; 1101' to the specific location of the handle, as these parts may be evidently modified without avoiding the main feature of my invention.

I claim as my invention- 1. In combination with the sliding sash, the lock-case adapted'to be secured to one of the sashes, a sliding bolt borne in the lock-case and having a limited rotary movement, a spring operatingto hold the bolt in its retracted position, the handle appurtenant to the bolt, and the catch-plate bearing the inward-facing locking-sockets, all substantially the bolt, and the guide-socket in the bolt as described.

case, all substantially as described. 2. In combination with a slotted catchv plate having inward-facing locking-sockets 5 arranged adjacent to the slot, a bolt-case supporting a spring-seated sliding bolt with a T- shaped fastening end, the guide-pin borne on THEODORE NEWTON. Witnesses:
