UNITED STATES JAMES EDWIN GIBBS, OF CLIFTON FORGE, VIRGINIA.

SASH-FASTENER.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed December 20, 1906. Serial No. 348,761.

To all whom it may concern:

Be it known that I, JAMES EDWIN GIBBS, a citizen of the United States, residing at Clifton Forge, in the county of Alleghany and State of Virginia, have invented a new and useful Sash-Fastener, of which the following is a specification.

The invention relates to improvements in sash fastenors.

The object of the present invention is to improve the construction of sash fasteners, and to provide a simple, strong and durable sash fastener, adapted to be cheaply manufactured, and capable of being readily applied to a window and of securely locking the upper and lower sashes thereof, either closed or open to a greater or less extent.

A further object of the invention is to provide a such fastener, which, while capable of use on windows having counter-balancing weights, will be especially adapted for locking the sashes of a window not provided with such weights, and which will enable either of the sashes of a window to be either raised or lowered without unlocking or affecting the adjustment of the other sash.

Another object of the invention is to provide a sash fastener, which cannot be left unlocked and which will effectually prevent one of pair of sashes from accidentally falling while the other is being adjusted.

The invention also has for its object to provide a sash lock having independently operable spring-actuated dogs, normally engaging the sashes and adapted to be disengaged from the same by a key, and to provide means for enabling the dogs to be positively moved into engagement with the sashes by the key, should the spring become broken, or otherwise inoperative.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawingz-Figure 1 is a vertical sectional view of a window provided with a sash fastener, constructed in accordance with this invention. Fig. 2 is a vertical. sectional view, taken substantially on the line 2-2 of Fig. 1. Fig. 3 is a horizontal sectional view, taken substantially on the line 33 of Fig. I. Fig. 4 is a detail view of a portion of the window frame, the sash fastener being shown in elevation. Fig. 5 is a detail perspective view of the supporting plate. Fig. 6 is an enlarged detail sectional view, illustrating the arrangement of the arcuate recesses and the rib or feather of the key. Fig. 7 is a detail perspective view of one of the dogs. Fig. 8 is an enlarged detail view, illustrating the construction of the intermediate connecting portion of the spring and the manner of mounting the same on the supporting plate.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

].1 designate similar interchangeable substantially L-shaped dogs, extending upwardly and downwardly and adapted to engage the upper and

lower sashes

2 and 3 of a window 4;, the upwardly extending dog being arranged to lock the upper sash and the downwardly extending dog the lower sash. The dogs arepivoted at their inner or proximate ends at the transverse center of a supporting plate 5, and they have bills or engaging portions 6 at their outer ends for engaging the sashes.

The sash fastener is mounted on the window at one side'thereof, and the adjacent edges of the upper and lower sashes are provided with suitable openings'or sockets, which may be formed by boring openings 7, or by cutting recesses 8. Any number of such openings may be provided to afford the desired adjustment of the sashes.

The supporting plate is mounted on the window frame or casing at the adjacent ends of the upper and lower sashes in position to be concealed by the same, when the same are closed, and the said supporting plate is provided with upper and lower end openings 9, through which the engaging portions of the dogs project. The plate 5 is provided at the center with a substantially rectangular bearing 10, provided at opposite sides with hearing openings 11 and having a threaded opening 12 at the transverse connecting portion or back. The openings 11 receive a key 13, which is provided at its outer end with a suitable head and which is mounted adjacent to the head in a thimble 14. The thimble 14 frictionally engages the walls of a horizontal opening of the window frame, and is thereby securely held in place without the use of screws, or other fastening devices. longitudinal rib or feather 15, and the end of the thimble is retained on the shank or spindle portion of the key between the head and the adjacent end of the feather or rib. The feather or rib is normally arranged in rear arcuate recesses 16 of the proximate ends of the dogs, which are provided with openings to receive the shank or spindle portion of the key. The key forms a pivot for the dogs, and the shoulders or end walls 16 of the arcuate recesses 16 are arranged in pairs and extend outwardly beyond the bearing faces of the bearing openings of the dogs. The rib is adapted to engage the lower shoulder or end wall of the recess of the up per dog to swing the latter out of engagement with the upper sash, and the key is adapted to be turned in the opposite direction to cause the rib or feather to engage the upper end wall or shoulder of the arcuate recess 16 The key is provided with a of the lower dog to disengage the same from the lower sash. By this construction, the dogs are operated independently to disengage them from the sashes, and one of the sashes may be adjusted without affecting the adjustment of the other sash.

The dogs are normally held in engagement with the sashes by a spring 17, but in order to enable the dogs to be positively moved into engagement with the sashes by the key, should the spring become broken, or otherwise defective, the dogs are also provided with front arcuate slots 18, having walls or shoulders 18 and the key is adapted to be pulled out of the openings of the dogs and the rectangular bearing and reversed to arrange its rib or feather in the recess 18.

The spring consists of upwardly and downwardly extending arms, spaced apart to engage the rear faces oi the dogs near the outer ends thereof, and connected by a horizontal transverse portion 19, which is provided at its center with a curved bend or loop 20, extending around one side of the threaded portion of a screw 21, as clearly illustrated in Fig. 8 of the drawing, and engaged by the head of the screw, whereby the spring is securely clamped on the connecting portion of the rectangular bearing. The screw engages the threaded opening.

The supporting plate is provided at opposite sides of its inner or rear face with longitudinal enlargements 22, tapered from the center to the ends of the supporting plate and forming inclined seats for the dogs, whereby the openings are maintained in alinement, when the key is not in engagement with the same. The dogs will be held on the seats by the arms of the spring, and this construction will be found advantageous in assembling the parts and when removing and replacing the key. The dogs are held from lateral movement on the seats by longitudinal flanges 23 and the intermediate rectangular bearing.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent,

isz
