SASH-LOCK.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed March 22, 1905. Serial No. 251A.

To all whmn it may concern:

Be it known that 1, CHARLES M. EVANS, a citizen of the United States, residing at Oarmichaels, in the county of Greene and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification.

This invention relates to sash-fasteners, and more particularly to that class of fasteners which perform the double function of locking the upper and lower sash against relative movement and also of locking the sash to which it is attached to the window-frame.

The object of this invention is to provide a sash-fastener of the kind mentioned which shall be simple in construction, effective in operation, and cheap to manufacture.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar numerals of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of my invention, showing it attached to the top of the lower sash. Fig. 2 is a vertical longitudinal sectional View. Fig. 3 is a vertical transverse sectional view on the line 00 w of Fig. 2, showing the invention as applied in looking the two sashes together.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 indicates the casing or framework within which the bolts operate. This casing is secured, preferably, as shown in the drawings, to the left-hand side of the top of the lower sash by means of screws 2 through the top and also by screws passing through the flanges 3 and 4, which extend, respectively, along the side and top of the sash. The groove 5 is provided in the end of the casing, so that it will not interfere with the operation of the sash-cord. The bolt 6 slides longitudinally through the casing in holes for that purpose and is operated by means of the knob 7, which is attached to the bolt, and slides through a slot 8 in the top of the casing. The bolt 9 slides transversely and directly under the bolt 6 in holes for that purpose and is operated by a handle 10 at one end thereof. A pin 11 is extended from the bolt 9 at a point between its ends, so that when it is turned up back of the bolt 6, as shown in Fig. 3, the bolt 9 is locked against movement and can only be withdrawn by first turning it through a quarter-revolution.

The numeral 12 designates any suitable socket, which is adapted to be driven into holes bored at suitable intervals in the window-frame and also in the side stile of the upper sash, said sockets to be so placed that they will be in operative connection with the respective bolts in the sash-fastener.

The operation of the device is as follows: By pushing the knob 7 to one side of the slot 8 the bolt 6 is withdrawn and the lower sash may be raised to any desired height and then locked by pushing back the knob 7 and throwing thebolt 6 into engagement with the selected socket. It will thus be seen that the lower sash can be securely fastened at any desired By turning the handle 10 throu h ing, the two bolts 6 and 9 mounted in said cas- 7 ing and slidable at right angles to each other, the finger-piece 7 projecting upwardly from the bolt 6 through the top of the casing, the casing having a slot therein in which the finger-plece 7 is adapted to slide, the fingerpiece 10 at one side of the casing and carried by the outer end of the bolt 9, and the pin 11 projecting upwardly from the bolt 9 between the ends of the latter and arranged within the casing aforesaid, the bolt 6 being
