SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 234,071, dated November 2, 1880.

Application filed August 25, 1880. (No model.)

To all whom it may concern Be it known that I, ADDIsoN V. SANFORD, of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification.

My invention relates to sash-holders especially adapted for the windows of railway-cars, but also adapted to other windows; and the IO object is to obtain a sash-holder of simple construction which will serve to hold the window open, and also to lock it when closed.

To this end the invention consists in the combination, in a sash-holder, ofa case adapted 1' 5 to be secured to the face of a window-sash, and

constructed with openings in its opposite sides and a thumb or finger piece, a pivot in said case, a bolt-arm having both a swinging and a longitudinal movement on said pivot, and havin g projecting from opposite sides of its swinging end a bolt-nose and a thumb or finger piece, which protrude through the openings in said case, and also having a notch to engage with one edge of that opening in the case through 2 5 which the said thumb or finger piece protrudes,

to hold the bolt-arm against accidentally swin ging. The bolt-nose is adapted to engage with the window casing or frame, while the thumb or finger piece affords convenient provision for 0 moving the bolt-arm longitudinally to free the notch from the case, and for swinging it upon its pivot to draw in the bolt-nose. I also preferably combine with the above a spring for moving the bolt-arm to cause the bolt-nose 3 5 to engage with the casing or frame to lock the window.

In the accompanying drawings, Figure 1 represents an inside face view of my improved sash-holder, showing the parts in their locked position. Fig. 2 represents a view similar to Fig. 1, except that the bolt-arm has been moved longitudinally to disengage its notch from the case, and it also represents, in dotted outline, the position of the bolt-arm and 5 appurtenances when swung into position to unlock the sash; and Fig. 3 represents an edge view of the sash-holder.

Similar letters of reference designate corresponding parts in all the figures.

Adesignates a case, which is provided with screw-holes a, for the reception of screws to attach it to a window-sash, and the open side of which is closed by securing it upon such sash. The case is constructed with a thumb or finger piece, A, and with openings 1) c in its opposite sides, the object of which will be presently explained. Projecting from the inner side of the case is a pin or pivot, 01.

B designates a bolt-arm secured at one end to the pivot 01, and adapted to be swung back and forth within the case. From one side of the swinging end of said bolt-arm projects a bolt-nose, B, which protrudes through'the opening I) in the case, and from the opposite side of said swinging end projects a thumb or finger piece, B which protrudes through the opening 0 in the case.

When the case is secured to the face of a sash the bolt-nose B is adapted to engage with stops upon or in the window-casing or frame and hold the sash when raised, and by applying the thumb and finger to the thumb or finger pieces A B the bolt-nose may be withdrawn and the sash lowered.

To cause the bolt-nose to engage automatically with the stops upon the casing or frame, I employ a spring, 0, coiled around the pivot d, and one end of which engages with the boltarm, while the other end is held against the case.

It is obvious that if the sash-holder were secured to a sash'and employed to prevent the raising of the sash any force exerted upon the sash to raise it would act upon the bolt-arm B in the direction of the arrow e, and that such a force would be very apt to swing the bolt-arm and unlock the sash unless means are taken to prevent this.

In order to prevent the bolt-arm from being so swung, I make the hole 8, which fits upon the pivot d, slightly elongated, so that the bolt-arm may be afforded a longitudinal movement, and in the lower portion of the thumb or finger piece B is a notch, f, which is adapted to engage with the edge of the opening 0 in the case, and thus locks the bolt-arm securely against swinging unless it is first moved longitudinally. The first pressure exerted upon the thumb or finger piece Wraises side of the same. Such, broadly, I do not the bolt-arm sufficiently to disengage the notch f from the case, and a continued pressure swings the bolt-arm and draws the bolt-nose 5 B within the ease to unlock the sash.

By my invention 1 provide a sash-holder which may be very conveniently applied to a Window-sash, and which may be made to hold the sash against being raised as well as to hold it against falling when raised. i

Heretofore night-latches have been made, in which the locking-bolt has been slotted to permit it to swing and at the same time move longitudinally, and such I disclaim; and a sash-fastener has been constructed of a casing having in its opposite sides apertures, a swinging bolt being pivoted in the casing, and having a nose projecting; through the opening in one side of the casing and a thumb-piece pro- 20 jecting through the opening in the opposite claim; but

What I claim as my invention, and desire to secure by Letters Patent, is-

In combination with the casing A, provided with the openings 1) and e and having the pivot d fixed within it, the locking-bolt consisting of the horizontal bolt-nose B, the horizontal thumb-piece 13*, having the lockingnotch f, and the vertical arm B, formed at its upper end with the elongated slot .9, through which the fixed pivot passes, and on which the locking-bolt is capable of a combined swinging and longitudinal movement, all as herein shown and described.
