SASH LOOK FOR RAILWAY CAR WINDOWS.

- Application filed October 2 '0 a]? whom it may concern e it known that I, EDWARD F. Cnarrnn, a citizen of the United States, and a resident of Syracuse,

in the county of Onon- York, have invented a certain new and useful Sash Lock for ltailway-Car Windows,

of which the following is a specification.

This invention holders for dows, of the relates to sash looks or windows, as railway car wintype shown in my Patent N 0.

1,349,046, dated Aug 10, 1920.

he invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In had like characters describing this invention reference is to the accompanying drawings in which designate corresponding parts in all the views.

Figure 1 1s a transverse sectional view of one form of my tions of the sash also shown.

shown in my patent 1,349,046, the operating member interlocks with the casing and mounted in position is not possible for become displaced,

when the sash lock is on the window sash it the operating member to but when the lock is not mounted on the window sash, but is being held in the hand and the operating member manipulated more or less violently, the op 9, 1923. Serial No. 667,496.

crating member sometimes shifts outwardly when the bolt is in its retracted position. and comes out of interlocking relation with the case and becomes detached from the bolt, and the bolt due to the spring is shot out of the case. This result is not possible in the practical use of the holder, but happens at times before the sash lock is mounted in position and is being manipulated aimlessly.

The object of the invention is therefore,

a sash lock, in which the operating member is so interlocked with the bolt that said member cannot be displaced and release the bolt except by manipulation of the bolt and the lever with the intent to displace the operating member.

1 designates the casing which may be of any suitable form, size and construction, it being here shown as in the form of a box having an internal recess 2 opening through its rear face and having a passage 3 opening laterally from the recess'through a lateral or edge wall of the casing. The casing is also formed with flanges 4 at its upper and lower ends which lie on the sash and through which the fastening screws are passed into the sash.

The casing is also formed with a handle or grip 5.

6 is the locking member in the form of a bolt, it being here shown as slidably mounted in the casing and movable through the passage The bolt having teeth 7 at its outer end for coacting with a complemental rack on the window stop 9, as will be understood by those skilled in the art, it being understood that a sash lock is usually arranged on one or each lower corner of the sash. The bolt 6 is also guided in the opposite lateral wall of the casing to that in which the passage 3 is formed, and it is here shown as formed with a stem 10 extending parallel to the direction of the movement of the bolt and slidable in a suitable guide 11.

compression spring 12 encircles the stem and tends to press the bolt outwardly into its operative or locking position.

13 is the operating member which is here shown as in the form of a lever, having a handle 14 near the handle 5 in the side wall of the casing, the handle 14; being usually located above the grip or punch handle 5, in order that both handles 14 and 5 may be engaged at the same time.

The lever 13 is detachably mounted in therecess and is movable into and out of the recess, preferably by an axial movement and is normally held from displacement by means interlocking with the bolt 6. lhe bearing for the lever 1.3 is usually a stud 16 provided in the recess 2 and projecting "from the front or bottom wall thereof towards the open side of the recess, the lever being formed with a hub or bearing 17 mounted on said stud. The lever l3'is also formed with an angular arm 18 which is connected to the bolt 6 by a pin-and-slot connection, in such manner as to actuate the bolt when the lever is operated. It being here shown as having a lateral projection or pin workingin a vertical slot 19 in the and lower edges of the bolt.

The means for interlocking with the bolt and holding the lever from axial displacement, comprises a projection or arm 20 extending rearwardly from the pin of the pinand-slot connection and hooking behind the bolt 6.

This projection, arm or hook 20 extends rearwardly with respect to the movement of the bolt by its spring 12 so that the spring in addition to thrusting the bolt into operative position, also tends to hold the lever in the slot and in interlocking engagement with the bolt, and thus parts can be disconnected only by intentionally retracting the bolt 6 inwardly against the force of the spring 12 and holding the lever 13 from movement or bolt between the upper retracting so that the bolt when being so moved is shifted out of interlocking engagement with the projection 20, and thus while the bolt is held retracted to the lever, can be removed or placed in position.

Furthermore, the lever cannot be removed. or displaced upon manipulation of the lever 3 when the casing is not mounted upon a window sash.

What I claim is:

A sash lock, comprising a casing former with a recess opening through its rear face,

a bolt movable transversely of the recessthrough a lateral wall of the recess, a spring acting on the bolt, and normally tending to press it outwardly into locking position, an operating lever mounted in the recess and removable and replaceable by an axial movement of the lever, the lever having an arm detachably engaged with the bolt by a pin and slot connection, said arm having projection interlocking with the bolt one end of the slot, to normally revent axial dis placement of the lever, said arm benigarranged so that upon niovement of the bolt against action of the spring relative to the operating lever, the bolt moves out of looking engagement with said arm to permit anial displacement of the lever.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 5th day of @ctober, 1923.

EDWARD F. CHAF-FEE.
