Application filed June 30, 1913.

'1 b all whom it may concern:

Be it known that I, JOSEPH E. RANDA, a citizen of the United States, residing at Highland Park, in the county of Wayne and State of Michigan, have invented a new and useful Sash-Fastener, of which the following is a specification.

My invention relates to sash fasteners; and the object is to provide a device which when applied to a window sash may hold the window sufiiciently open for ventilation but will not permit unwarranted further opening of the window from the outside by burglars or other intruders. The device may also be used as a substitute for sash weights, and will hold the window closed when so desired; so it really serves the purposes of three devices, namely to hold the sash raised, hold it raised and locked, and hold it locked when closed.

In the accompanying drawing, Figure 1 is an inner side elevation of a portion of a window sash and the adjacent frame, the latter in section as on the line aa Fig. a, with my invention applied thereto. Fig. 2 is a portion of a window frame with the sash removed, showing the perforated metal strip secured on the frame for the locking device to engage. Fig. 3 is an edge view of the sash provided with the locking means of the device and adapted to slide against the strip in Fig. 2. Fig. 4; is a horizontal section of a window frame and a pair of sash hung therein, the sash having the lock ing device being intersected substantially on the line Z)-Z) Fig. 8. Fig. 5 is a bottom view of the device proper removed from the sash and having its operating button removed. Fig. 6 is a section on the line c-c Fig. 5. Fig. 7 is a detail side view of the screw stud 19 in Figs. 5 and 6, but it also shows the shape of the screw 22 in Fig. 1.

Referring to the drawing by reference numerals, 1 designates the frame, 2 and 2 the parting strips, and 3 the inside stop of a window opening. Slidably fitted between said strips 2 and 2 is the upper window sash 4, having the glass 5, while between the stop 3 and the parting strip 2 is slidably fitted the sash 4*, having the glass 5 and constituting the lower and inner sash of the window. As both sashes are or may be equipped with the same kind of fasteners, only one fastener need to be described, and the same is as follows: As a necessary part of the device when it is properly made, a

met-a1 strip or plate 7 is secured by screws 6 upon the frame. Said plate may have teeth or any suitable kind of indentures, but in the drawing I have shown plain holes 8, for the locking bolt 9 to engage. Said bolt is slidable in a hole in a cylindrical body or casing 10, which is adapted to gointo a cylindrical hole in the edge of the sash and is provided with flanges 11 having holes 12 for screws 13, which hold the device in place. Said cylinder may have one side slightly flattened as at 14, but otherwise the cylinder is solid except for the holes bored in it. Said holes are, one for the bolt 9 and a spring 15 partly compressed between the end of the bolt and the bottom of the hole; another hole is for the rack bar 16, which slides across the locking bolt and is geared to it by a cog-wheel or pinion 17 the latter is loosely fitted in a hole 18 and rotates on a screw 19 (see Figs. 6 and 7), which screw has a shoulder 20 to limit its forward progress and to hold the screw steady as a stud on which the pinion rotates guarded by the head 21 so it can not escape from the stud. Another screw, 22, similar to the screw 19 in Fig. 7, is threaded at 23 into one end of the rack 16, and is provided with a head 24L which serves as a press-button, and is slidable in a thimble 25, which is inserted in a cylindrical hole in the inner side of the sash and is provided with ears 26 secured by screws 27 to the sash.

On ordinary windows the locking device is inserted in the sash about twenty-two inches from the bottom of the lower sash, and a similar distance from the top of the upper sash to the fastener used on the upper sash, so as to bring the locking devices out of reach by a persons hand standing outside the window when the sashes are partly opened for ventilation above and below them.

If the sashes are hung by the cords and weights, such hanging does not interfere with this fastener, and if there are no sash weights, my device will effectively hold the sashes at any desired elevation, and will also look them in closed position.

Whenever the sash is to be moved up or down, the operator, being inside the room having the window, simply presses on the button 24 and the rack 16 will rotate the pinion 17 and thereby retract the bolt 9 from the strip 7 on the frame.

In one side of the thimble is a hole 28 for the insertion of a wire peg or key 29 (see Figs. 1 and t). Said key serves to hold the press button depressed and thereby the locking device idle or unlocked While the windows are being washed, or when it is otherwise desired to have the windows for a time moving freely. Said key 29 is suspended by a cord or chain 30 near the lock, so as not to get lost, but to be handy whenever wanted.

The screw heads 21 and 2% are each provided with a notch 31 for a screw-driver to take hold in when the screws are to be removed, or when they are to be inserted and screwed tight, in assembling the parts of the mechanism.

hat I claim as new, and wish to secure by Letters Patent, is:

1. The combination with a window frame, of a serrated or perforated plate secured thereon, a sash arranged to move close to said plate, a metal casing carried by the sash, a cog-pinion mounted in the casing, two racks meshing with the pinion, one of said racks having one end arranged to en ter into the plate, a spring acting on the rack to push it toward the plate, the other rack having at one end a push-button op erable from the inner side of the sash and located out of sight from outside the window and so far from the end of the sash, that is to be opened, that it can not be reached and operated from without the window when the window is partly opened for ventilation.

2. The combination with a window frame, of a serrated or perforated plate secured thereon, a sash arranged to slide along said plate, a metal casing carried by the sash, a cog-pinion mounted in the casing, two racks meshing with the pinion, one of said racks arranged to enter into the plate, a spring pushing said rack toward the plate; the other rack having at one end a push-button operable from the inner side of the sash and concealed in a cavity therein and located so far from the opening end of the sash that it can not be reached and op erated from without the window when the latter is partly opened for ventilation; and

means for locking said push-button in depressed position when so desired.

3. The combination with a window frame and a vertically disposed serrated or perforated strip secured tiereon, of a sash guided to slide with one edge along said strip and having in said edge a cylindrical cavity, and communicating therewith a second cylindrical cavity in the inner side of the sash; a metallic cylindrical casing inserted in the first mentioned cavity and secured to the sash, a spring-pressed bolt slidable in the casing and arranged to enter into the strip, said bolt having at one side cogs, a stud in the casing, a cog pinion mounted on the stud and meshing with said cogs, a short rack slidable in the casing in crossing position to the bolt and engaging the pinion, a guiding metal thimble in the cavity of the inner side of the sash, a push-button slidable wholly within said thimble, and having a stem threaded into the adjacent end of the short rack.

4. The combination with a indow frame and a vertically disposed perforated strip secured thereon, of a sash guided to slide with one edge along said strip and having in said edge a cylindrical cavity, and communicating at right angles therewith a second cylindrical cavity in the inner side of the sash; a metallic cylindrical casing inserted in the first-mentioned cavity and secured to the sash, a spring-pressed lbolt slidable in the casing and arranged to en ter into the perforations of the strip, said bolt having at one side cogs, a stud in the casing, a cog-wheel mounted on the stud and meshing with the cogs of the belt, a short rack sliding in the casing in closing position to the spring-pressed bolt and meshing with the cog-wheel, a push-button movable wholly within the second cavity of the sash and operatively connected with the short rack.

In testimony whereof I atlix my signature, in presence of two witnesses.
