PATENT HIRAM T. KING, OF ROCHESTER, NEW YORK.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 276,050, dated April 17, 1883.

Application filed March 27, 1882. i

To all whom it may concern:

Be it known that I, HIRAM T. KING, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Sash-Locks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, in which- Figure l is a plan of the device attached to the meeting-rails of two sashes and locking them together. Fig. 2 is a vertical cross-section in line was of Fig. 1. Fig. 3 is afront edge view of the case, showing the locking socket or slot.

My improvement relates to looks for securing the meeting-rails of sashes, and is of that class where one half of the lock-case is on one rail and the other half on the other rail, and a lever is used pivoted to one half, which lever swings over the other'halt', thus preventing the upper sash from falling and the lower sash from rising.

My invention consists in the combination of the rear part of the lock-case provided with an eccentric pivot, reversible in position, a swinging lever, having a hook on its outer end, turned downward and backward, and the front part of the lock-case, formed with a hole or slot, and with a guide-rib, all constructed, arranged, and operating as hereinafter specified.

In the drawings, A A show the meetingrails of two sashes, one being the upper and the other the lower sash.

B B are the two halves of the lock-case, one half being secured to one rail and the other to the other rail by screws, as shown. The case may be circular, or of any other form desired, but is made hollow on the under side. In the front edge of the outer half is made an open notch, a, which opens through the shell to the interior, and on one side of the notch is a horizontal guiding-lip, c, which projects over, forming a rib, and extends along some distance, finally vanishing in the circle of the case.

0 is the swinging lever, pivoted to the inner half of the case and swinging across the joint, and having at its outer end a book, 1), which No model.)

engages with the slot a. Thelower end of the hook is turned inward and backward horizontally, and when the lever is turned forward this hook passes under the lip c and is guided by it to the notch.

D is the eccentric and pivot upon which the lever turns, the lever having an eye or hearing, d, which fits upon the eccentric, as shown in Fig. 2. The eccentric consists of the eccentric portion f, upon which the eye of the lever fits, a thumb-piece, g, or other device at the top, by which the eccentric is turned, and a pin, h, at the bottom, fitting in a socket of the case, and forming the center on which the pivot turns, said pin having a washer, '5, below, or being otherwise attached to retain its place.

So far as the mere use of a divided case attached to the rails of the opposite sashes and a pivoted lever which swings across the joint and prevents the sashes from being moved is concerned, they are similar to other sash-locks now in use; but in addition to these features the eccentric to which the lever is pivoted gives an end or drawing movement to the lever when operated, and causes the hook I) to strike into the slot a, thereby locking the le ver in place and preventing it from being either pushed up or turned around. The eccentric acts the double purpose of an eccentric to operate the lever and a pivot toturn it around upon. A half-turn of the eccentric in either direction is sufficient to lock or unlock the lever, and when free it can be swung freely around the same, as any lever in this class of locks. In this invention the lever is positively locked in place and is immovable till unlocked again; hence it cannot be moved by inserting a knife or other thin instrument in the crack between the rails, as in many locks of this class. The lever is held open by turning over an inclined lug and stop, 1", on the case, or by any other suitable means.

I do not claim, broadly, in a sash-lock, a swinging lever, an eccentric,,or a hollow case; but

1 claim- In a sash-lock, the combination of the rear lock-case provided with an eccentric pivot, D,

reversible in position, the swinging lever G, In witness whereof I have hereunto signed having a hook, I), on its outer end, turned my name in the presence of two subscribing downward and backward, and. the front lockwitnesses.
