FASTE NER FOR MEETING-RAILS OF S ASHES.

SPECIFICATION forming part of Letters Patent No. 280,935, dated July 10, I883.-

(Modem To all whom, it 12 2.614, 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 had to the accompanying drawings, in which 7 Figure l is a plan of the device applied to the meeting-rails of the two sashes. Fig. 2 is a vertical section of the same in line at w of Fig. 1. Fig. 3 isv a front elevation of the case.

Fig. 4. is a plan of the forked catch removed from place. Fig. 5 is a diagram showing a cross-section of the fixed pin and a plan of the cam fitting the squared side thereof.

My improvement relates to looks for the meeting-rails of sashes, and is of that kind where a swinging lever is attached to a pin, on which it turns and engages by a hook with a notch in the front edge of the plate or case.

The invention consists, essentially, in the combimtion of a fixed pin or stud having squared sides, and a locking-catch and cam operating as hereinafter more fully set forth.

In the drawings, A A show the meetingrails of two sashes.

B B are the two segmental plates which form the case, being attached respectively to the two rails, as usual. On the inner edges of the halves of the case are vertical flanges a. rawhich are screwed to the faces of the rails to give additional strength to the parts; but, if desired,

. these flanges may be dispensed with. In the 'eting it, or otherwise attachingit.

front edge of the outer plate is an open notch, 2), into which the hook of the locking-catch strikes, and above this is a concentric horn or arm, a,'under which the catch passes, as will be presently described. This, however, may be dispensed with.

C is a vertical pin or stud rising from the rear plate of the case, and made fast thereto, either by casting it solid with the plate, riv- On top of the stud isa fiat cap or head, (I, which holds the lockingcatch in place. In cross-section the stud has two squared sides, f f, Fig. 5, at right angles to each other; but the balance of the stud is circular, and the squares are also a little shorter than the full length of the stud,

leaving a small circular bearing both above and below. One of the squares stands parallel with the length-of the rails and the other at right angles thereto. a i.

D is the locking lever or catch, the same consisting of an arm, g, with a hook, h, in front and two branches or forks, ii, inthe rear, which embrace the stud and rest below the flat head thereof.

E is the cam, consisting of ale'ver pivoted at rear of the stud. Thiscani is substantially of the form shown, and it has a square front end,

The squares are made concentric with the pivot of the cam, so that the cam will retain a hold on the stud at all times, except when turned up vertically, as shown by dotted lines, Fig. 2, in which case the cam releases its hold and allows the locking-catch to slide forward on the stud sufficiently for the hook h to disengage from the notch b, in which case the lock= ing-catch can be swung around out of engagement. When the cam is thrown down, as shown in full lines, the point of the cam stands perfect lock. The cap or head of the stud is of such size as to cover the opening or slot of the locking-catch at all times whether thrown forward or back.

The operation is as follows: The lockingcatch is turned under the horn c'till the hook h comes in line with. the notch Z). The lever of the cam is then pressed down, the cam riding=upon the square f, which draws the lock ing-catch back and draws the hook into the notch, as shown in Fig. 2. A double lock is thus produced, first, by the engagement of the hook with the notch, which will not allow the catch to be either thrown forward or back, or be raised vertically, and, second, by the bearing of the square end of the cam against the square side of thest-ud, which will also prevent turning. In addition to this, the horn 0, when used, prevents the catch from being turned. To unlock the catch, the lever of the cam is raised, as shown by dotted lines, which allows the catch to slide forward till the hook is dis engaged, and the cam and catch are then swung around at right angles, as shown in the dotted k to the forked ends of the locking-catch in the,

which rests'against the square f of the stud;

above the level of the pivot and produces a lines, Fig. 1, and the cam is then looked in a similar manner to the other square of the stud, which holds it fast and out of engagement, so that the lower sash can be raised or the upper one lowered. r

7 One advantage of my invention is that the cam can be operated to disengage the catch,

and the catch can then be swung around at one operation and requiring but one hand of the operator, leaving the other hand free to operate the sash, whereas in ordinary sashfasteners of this kind it takes both hands to operate the fastening, one being required to.

. insertion of any instrument through the joint for the purpose of turning the catch.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. In a sash-lock, the combination of the stud having one or more squared sides and a coveringcap or head atits top, the lockingcatch provided with a book which engages with a notch in the case, and with forks which embrace the stud, and a cam pivoted to the catch and engaging with the square side, of the stud to lock the catch in place, as set forth.

2. Ina sash-lockfthe fixed stud 0, provided with two squared sides at right. angles to each other,and concentric with the pivot of the cam, which fits said squared sides, as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

HIRAM IT. KING.
