JOSEPH ROBERT VHEM, OF DENVER, COLORADO.

SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 403,810, dated May 21, 1889.

Application led February 2G, 1889. Serial No. 301,230. (No model.)

locking or holding the sashes of a window at any desired point.

The invention is alike applicable to windows with or without weights, and comprises means -whereby the upper sash of a window where weights are not employed can be held locked while the lower sash is unlocked.

The invention also comprises the details of construction, combination, and arrangement of parts, substantially as hereinafterfully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a view of a section 01": a window with my improved sash-fastener secured thereto. Fig. 2 is a rear view thereof. Fig. 3 is a detailview of one of the catches and its operating-dog. Fig. 4 is aview of a modited form of said dog.

Referring to the drawings, A designates a plate which is set in the j amb of awindow at the point where the two sashes overlap, as indicated in Fig. 1.

B is a rod loosely secured to the rear side of this plate, the same being held or supported by apertured ears or lugs a a', attached To this rod B is secured, fast therewith, the upper end of a catch, C, for locking the lower sash, C', ihe lower angular end of said catch being extended through an aperture, b, in plate A, and is designed to engage a rack-bar, b', secured to the side of the window-sash C. A spring, D, is secured at one end to plate A, its lower end bearing against a tongue, d, of catch C. The office of this spring is to hold the catch O in engagement with the rack-bar bA E is a second catch for holding or locking the upper sash, E. This catch E is loosely secured or pivoted on a cross-rod, e, of two of the apertured ears a a', the upper angular end of said catch being projected through a second aperture, e', of plate A, and engagesa rack-bar, e2, of the window-sash E. This upper catch, E, is operated by a dog, F, rigidly secured to rod B, the upper end of said dog being provided with end shoulders, f f, which come in contact with a tongue, f', projecting from the lower end of catch E between said shoulders.

For windows where weights are not employed, I use the form of dog above described, and shown in Fig. 3, while in windows where weights are attached to the sashes the form of dog shown in Fig. et is adopted. The former construction permits the upper sash to be held locked, while the lower is unlocked; but where weights are used such is not necessary. The latter construction provides for the simultaneous operation of the catches, both shoulders ff being always in contact with the tongues f. A ringer-bar, G, is rigidly secured to rod B, and is extended through an aperture of plate A, so that the parts can be operated.

It will be seen that by pressing down to a limited extent on the linger-bar G rod B will be caused to make a partial revolution, withdrawing the protruding end of catch C from engagement with the rack-bar of the lower sash, and by further pressure on bar G the dog F will 'be made to act on the lower end of the catch, withdrawing the upper end thereof, and permit the moving of the upper sash. Immediately upon releasing the pressure from bar G the spring D will instantly return the parts to their former position.

ABy means of my invention the respective sashes of a window can be irmly locked at any desired point.

The principal advantage of my invention lies in the simplicity and durability of the part-s, which are not liable to easily get out of order or to become suddenly deranged.

I claim as my inventionl. As an improvement in sash-fasteners, the combination of the pivoted rod and the upper and lower catches, the latter being secured to said rod and operated in advance ot' the former, which is pivoted independent of said rod, substantially as set forth.
