JOHN WEIKERT, or INDIANAPOLIS, INDIANA.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 243,094, dated June 21, 1881.

Application filed December 6, 1880. (ModeL) To all whom it may concern Be it known that I,JOHN WEIKERT, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvementin Sash-Locks, of which the follow' ing is a specification.

My invention relates to improvements in sash locks; and the objects of my invention are, first, to provide a device for securing a window-sash at any required place of adjustment, and prevent the sash from being raised or lowered from the outside; and, second, to prevent the sash from rattling. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a front elevation of the entire device as secured to the window-jamb. Fig. 2 is a side view of the same. Fig. 3 is a rear elevation of the same, showing parts which extend through the window-jamb. Fig. 4 is a sectional view of the lock-case and sashloeking devices. Fig. 5 is a front view of the lock-face. Fig. 6 is a sectional view of the locking-bolt, showing the serrated pawls for holding the sash pivoted in the head of the bolt. Fig. 7- is an end view of the bolt with the pawls removed. Fig. 8 represents a side and edge view of the key. Fig. 9 represents one side of the lock-case. Fig. 10 represents an end and side view of the cog-wheel for operating the bolt. Fig. 1L is an edge-view of the segmental ratchet and crank-arm for operating the bolt. Figs. 12 and 13 are side and top views ,of the segmental ratchet. Fig. 14 is a side view of the crank-arm and square rod for operating the bolt. Fig. 15 is a side view of the segmental ratchet, with the crank-arm partially in section, showing the manner in which the key operates the pawl-and-ratchet spring, and Fig. 16 is a view of the reverse side of the crank-arm and key from that shown in Fig. 15.

Similar letters refer to like parts throughout the several views.

A represents one of the side jambs of a window-frame, and B is the inside sash-strip. The jamb A has holes G and G cut through it to receive the lock and lock-operating devices.

The lock is composed of the face D, with boltopening D 5 the two sides,M M, with flanges d 01 and the bolt U, with opening 9 in its head to receive the pawls. E E, ratchet d on the inside of its upper prong, d, in which operates the cogs o of the wheel 0, the body of the wheel 0 operating in the space d between the prongs d d of the bolt, and the ends of the wheel 0, operating in holes 0 in the sides M M, all of which is shown in Figs. 4, 5, 6, 7, 9, and 10 in detail. Thelock is secured to the jamb A, as shown in Fig. 1.

The lock operating devices consist of the segmental ratchet F, having a downward projection, F, with hole It and slot S to receive the head L of the rod L and a side bracket, 6, by means of which the segmental ratchet is secured in the slot G of the jamb A, the window-strip B covering the bracket 0, so as to conceal it from view. On the rod L the lower end, P, of the arm I is made fast. The upper end of the arm I is provided with the spring H, one end of which is made fast to the arm, as aty, Fig. 1, and the other end of the spring operates on the ratchet-teeth of the segmental ratchet F. The arm I P is also provided with a groove, P, on one side, extending from the top to the head L of the rod L, to receive the key K, and is further-provided with a side recess, in which is pivoted the pawl J. The upper side of the outer end of this pawl J comes in contact with the loose end of the spring H, and the inner end of said pawl J is operated by the notch 'v of the'key K. Thus 'when the key K is inserted in the groove P of the arm I P, the notch 27 comes in contact with the inner end of the pawl J, depressing it and raising the outer end, which, in turn, causes the loose end of the spring H to raise out of the ratchet-teeth on the segmental ratchet F, and permitting the arm 1 P to be turned on its pivot L either up or down. At the same time the rod L, operatin g in the square hole formed in the cog-wheel 0, causes the bolt U to move either toward or from the sash, as required.

The operation is as follows: When it is desired to raise the sash, the key K is inserted in the groove P of the arm I P. The inner end of the pawl J ispressed down. The outer end lifts the spring H. The key is then moved down, causing the rod L and cog-wheel O to move the bolt U toward the sash. The pawls E E are thus forced against the edge of the sash with sufficient force to hold it in place. At the same time the key is drawn out, thus releasing the pawl J, and the spring H springs against one of the ratchet-teeth ot' the segmental ratchet F, and the sash is held firm. Any attempt to raise or lower the sash Without releasing the spring H from the ratchet will cause one or the other of the pawls E E to partially turn on the pivot m and bind the sash more firmly.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a sash-lock the lock consisting of the face D, with bolt-hole D, the sides M M, with flanges d d and holes 0, the bolt U, with space d between the prongs d cl, and the prong 01- provided with cogs (Z and the head of the bolt provided with a chamber, g, the serrated pawls E E, pivoted in the chamber at 122,

and the wheel 0, with cogs 0, all constructed and arranged to operate substantially as shown and described.

2. In asash-lock,the lock-operating devices consisting of the segmental ratchet F F, with hole R and bracket 6, the arm I P, with groove P in one side for the key K to operate in, and further provided with the spring H, the pawl J, and square rod L, with round head L, combined with the key K, having a narrow part, 8, and notch 11, and the lock device, as shown and described.

In testimony whereofl have signed my name
