DANIEL G. BOLTON, OF CAMDEN, NEW JERSEY.

SASH-LOCK- SPECIFICATION forming part of Letters Patent No. 783,013, dated. February 21, 1905. Application filed January 5, 1904. Serial No. 187,797.

1'0 all whom it may concern:

Be it known that I, DANIEL G. BoLToN, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented a certain new and useful Improvement in Sash-Locks, of which the following is a specification.

The invention while capable of use in other connections and for other-purposes is particularly designed for utilization as a windowlock, the object being to provide a device of this character which shall be simple and durable in construction and reliable in operation.

A further object is to provide a lock which shall securely maintain the parts engaged in their proper relation, resisting all ordinary effort of an unauthorized individual to tamper with the mechanism and release such engaged parts.

In carrying out the invention in an approved form, as embodied in a window-lock, I secure the same to the top of the lower sash of a window, providing the lower portion of the upper sash, as well as the adjacent jamb in which both sashes operate, with suitable recesses, with which or with certain of which coact bolts forming part of the lock and one or more being preferably spring-pressed to engaging positions. Said bolts are interdependent, and coacting with one or both thereof is a series of retracting-plungers arranged in such relation to said bolts or one of them as that their operation will withdraw said bolt or bolts from engaging position in order to release the sash and permit the window to be opened. The construction is such that one or both sashes may be locked at any desired position in the jamb, thereby making it possible to leave the window open, as for the purpose of ventilation, while at the same time guarding against unauthorized intrusion.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation illustrating the invention, one of the sections of the inclosing casing being removed. Fig. 2 is a horizontal section onthe line 2 2, Fig. 1. Fig. 3 is a cross-section on the line 3 3, Fig. 1; and Fig. 4 1s a bottom view. Referring to the drawings, 1n whleh similar letters denote corresponding parts, A designates the window-jamb, B the lower sash, and C the upper sash. Said ja'mb A and sash O are provided with a series of recesses a c, and, if desired, each of these may be provided with a bushing a 0, secured in position by means of screws a 0 As clearly shown in Fig. 1, the lock mechanism is mounted on the top of the lower sash B within a two-part casing D, the members whereof may be secured together by screws (Z. The under side of said casing is provided with keyhole-slots D in order that after the screws D have been placed in position the enlarged portions of said slots may be placed over the heads and the casing forced forward, so as to lock the bottom member thereof firmly under the heads of said screws. Any other preferred method of attachment may be usedas, for instance, integral ears formed on the casing and perforated for the reception of screws.

E designates the main bolt, here shown as provided at its forward end with the tubular member 6, operating through orifice in the casing and having inside of said casing the shoulder 6 The other end of said bolt is provided with two rearwardly-projecting extensions e 6*, operating 'in orifices 0" e in the rearward portion of said casing D. Said extension 6 is preferably provided with a coilspring 6 exerting a tendency to press the bolt E forwardly to engaging position. The primary function of extension 6* is to prevent the bolt E from turning. The under side of said bolt E is provided with ears a e", the function whereof will be presently described. The under side of said bolt E is also provided with two cut-away or recessed portions 6 a in such proximity as to form between them a tooth 6 As shown in Figs. 1 and 2, the forward end of said bolt E is adapted to coact with the recesses in the jamb A.

F designates a bolt arranged at right angles to the bolt E, theinner endf operating through an orifice f in the lock-casing and coaoting with one of the recesses 0 formed in the upper window-sash O. The front end of said bolt F is of less diameter and operates through orifice f in the forward member of said casing D. Said bolt is provided with an integral ear f carrying a pin f", operating through an orifice in the rear member of the casing and provided between said casing and said ear with a coil-spring f" the tendency whereof is to withdraw said bolt from engaging position, in which it is shown in Figs. 1, 2, and 3. Tlhe primary function of said pin f" is to prevent said bolt from turning. The bolt F is provided with a recessf and next to this a deeper recess The belt F directly underlies the recess a of the main bolt E when both bolts are in engaging position, the purpose whereof will be presently explained.

G G designate bolt-operating plungers, each having a beveled forward end 7 adapted to coact with the similarly-beveled forward faces of the ears 0 a" on the under side of the main bolt E. Each of said plungers operating through orilices in the casing D, as clearly shown in Fig. 2, is provided inside of said casing with arms g ,carrying pins 9 y, operating through orifices in the rearward member of the casing, said pins carryingcoil-springs g, the tendency whereof is to force said plungers G G outwardly t0 non-engaging position.

The purpose of the bolt-operating plungers Gr G is to withdraw the main bolt E from engaging position by the coaction of the beveled surfaces 1 of said plungers with the correspondingly-beveled surfaces of the ears a 0". This, however, may not be done until the bolt F has been pressed even farther than normally into its coacting recess 0, as will now be explained.

The looking or engaging position of the mechanism is illustrated in Figs. 1, 2, and 3. In this position the forward ends of the bolts E and F are located within one of the recesses a, and one of the recesses c. To unlock the mechanism that is, to throw the bolts to nonengaging or inoperative position it is necessary first to press inwardly the bolt F even farther than it normally extends to coact with the recess 0, for in its normal position rearward movement of the bolt E is precluded by the tooth 0 which coacts with the recess f. After boltFhas been pressed inwardly, however, the deeper recess f is brought into the path of said tooth 0 and bolt I therefore offers no obstruction to the rearward movement of said bolt E against the tension of its actuating-spring 0 Therefore upon pressing inwardly the bolt-operating plunger G the bolt E is so pressed rearwardly through the coaction of the cam-surface g of said plunger and that of the ear 0, thereby bringing the recess 0 in line with the main body of the bolt F and removing any obstacle to the passage of said bolt E. Under the influence of the spring f, therefore, said bolt F will quickly move to non-engaging position as soon as the recess 0 comes into alinement with it. By this means both the main bolt E and the bolt F may be withdrawn from engaging position and the sashes moved relatively to each other.

If the rearward movement of the main bolt E under the influence of the plunger G be insuflicient to free said bolt from its recess, the plunger Gr may be operated to move it still farther rearwardly through the coaction of its eam end with the camface of the ear (1". In fact, there may be any number of these plungers, and, if desired, some of them may be blind or inoperative, so that pressure only upon certain plungers will result in the rearward movement of the bolt E essential to throw both said bolt E and the bolt F to inoperative or non-engaging position. A lock so constructed offers an efficient safeguard against unauthorized operation.

To reloclz, it is necessary only to push inwardly the cross-bolt F. This will bring the deep recess into alinement with the tooth c of the main bolt E, whereupon said bolt E will snap to engaging position under the influence of the spring 6 IVhat I claim, and desire to secure by Letters Patent, is

1. In a lock, the combination withacasing, a bolt spring-pressed toward engaging position and another bolt arranged at an angle thereto, both said bolts coacting with sockets or re cesses outside said casing, of a retractingplunger arranged at an angle to the bolt first named and in a plane parallel with said angularlyarranged bolt and adapted to be manually operated, substantially as set forth.
