JOEL S. WHITEHURST, OF SAN JOSE, CALIFORNIA.

SASH-FASTENER.

Application filed April 14, 1913.

To all whom it may concern:

Be it known that I, J OEL S. VVHITEHURsT, a citizen of the United States, residing at 303 Minnesota avenue, San Jose, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification.

My invention relates to improvements in sash fasteners, and the objects of my invention are to construct a more economical sash fastener, and to construct a sash fastener by which the window may be more securely locked than is now the case with most of the fasteners now on the market.

I obtain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a window frame and sashes with my device in position, parts being broken away. Fig. 2 is a side elevation of a window frame with my device in position, parts being broken away. Fig. 3 is a sectional view on line A-A, Fig. 2.

The upper sash is marked 1, the lower sash 2 and the casing 3. My sash fastener is operated at the point of meeting of the two sashes, at one side of the casing, by turning key 4. This key passes into casing 3 and has a bearing 5 in the rear of said casing. Key 4 passes through escutcheon 6, countersunk in the face of easing 3. The end of key 4, next to bearing 5, is square, and passes through a square hole in tumbler 7. The rounded part of tumbler 7 is shown facing sashes 1 and 2 at their point of meeting. This tumbler turns in channel 7 cut in casing 3. The ends of the bolt levers, 8 and 8 rest on and bear against the opposite or flat side of tumbler 7. Bolt lever 8, with its lower end resting on, and bearing against, the uper portion of said fiat side, passes upward therefrom, as shown at Fig. 3. At the lower end of lever 8, passing through an oblong slot 9, Fig. 2, is a bolt 10. This bolt is flattened at this end to give it suflicient play in slot 9, with shoulders bearing against the inner side of lever 8, and a pin passing through its end on the outer side of said lever to hold it in place in slot 9. This pin is marked 11 in Fig. 2. Lever 8 has bearings 12 at its upper end secured in casing 3. The looped end of spring 13 bears against the outer face of lever 8 a distance from the upper end thereof. The ends of spring 13 are coiled around the bearing pin Specification of Letters Patent.

14, and bear against the side of casing 3, as shown at Fig. 2. I place a perforated strip of metal 15 on the edge of the window sashes, with holes therein at predetermined distances from each other, and bolt 10 passes in and out of these holes as the sash is locked or unlocked. The lower sash and sash lock are provided with like parts, and bear the same numerals, except that the letter a is applied thereto in addition to said numerals. Bolt lever 8 extends downward from tumbler 7, and the spring 13 is located at the lower end thereof, and the bolt 10 at the upper end. The sashes fit sufficiently snug in the casing to prevent the sash from lowering of its own weight when the bolts are removed. The sashes are raised and lowered by hand. My sash fastener is operated by turning the button 16 on key 4. When both of the bolts are entered in the holes of the metallic strips in the upper and lower sashes the tumbler 7 stands perpendicular in position, and by turning button 16 to the right the tumbler 7 pushes the lower end of lever 8 outward and bolt 10 is removed from a hole in strip 15. The upper sash is then lowered to the desired point and the button 16 is turned to its proper position, thus fastening the upper sash at the desired point. The lower sash is raised by turning button 16 to the left.

Having thus described my invention, what I claim is 1. In a sash fastener, the combination of a casing, a sash, a perforated strip secured in the edge of said sash, a semi-circular tumbler located in a channel in said casing, a bolt lever, equal in length, parallel with said sash, one end thereof bearing against the flat side of said tumbler and having bearings at its opposite end, a spring looped over and bearing against said lever at the bearing end thereof, a bolt loosely secured in a slot in said lever adjacent to said tumbler, passing inwardly and adapted to engage the perforations in said strip, and a key for turning said tumbler.

2. In a sash fastener, the combination of a casing, an upper and a lower sash, a perforated strip secured in the edge of each sash, a semi-circular tumbler, located in a channel in said casing at the point of meeting of said sashes, extending in part upward and downward from said point of meeting, bolt levers, parallel with said sashes, extending in opposite direction the full length cent to said tumbler, and a key passing of said sashes, one end of each lever extendthrough said tumbler. for operating the ing over and bearing against the flat side of said tumbler a distance, hearings in the same.

opposite end of each lever, a spring looped JOEL S. WHITEHURST. over and bearing against the outer side of Witnesses:

each lever at the bearing end thereof, a bolt JOHN A. NAISMITH,

loosely secured in a slot in each lever adja- F. C. BATES.
