Application April 5,

2V Claims.

The invention relates to window stops and locks adapted to use withsliding sash with or without counter-balances, and especially adapted to hold such windows locked at various positions. It. is an important object to present a device which is adapted to lock the window either in closed position or in partly raised position, and also adapted to support the sash in fully raised Y position. It is an important aim of the invention to present such a device the parts of which are adapted to be stamped from sheet metal and put in place properly by untrained persons, requiring only the use of a screw driver.

r Another important object is to present such adevice which, while enabling secure locking of a window so thatingress by a person outside the window cannot be readily gained, yet permits rapid and certain manipulation by any ordinary person or child to enable raising or lowering of the window when desired.

An important aim of the invention also is to insure safety against accidental dropping of a window without counter-balances when partly raised.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts involved in the embodiment of the invention, as will appear from the following description and accompany- `ing drawing, wherein:

Figure l is a fragmentary perspective view of the invention applied to an ordinary sliding sash and window frame, as it would be with the sash in closed position, an alternative use of the device l being indicated in dotted lines.

Figure 2 isa detail elevation of the stop and lock lever.

Figure 3 is a top view thereof.

Figure 4 is an elevation `of the keeper and safety belt.

Figure 5 is a perspectve'of one side of the window frame and lower sash in full raised position after onemanner of use of the invention.

There is illustrated a portion of a window frame lll of conventional construction including the sill I I, in which there is slidably mounted the lower glazed sash I2, guided by the inner stop I3. and parting bead or strip I4, the latter two parts forming the vertical guide channel I5 in which the sash slides. The sash includes the usual bottom and top rails I6 and l1, and side Stiles I3, only one side of which is shown. Secured by screws lil on the inner face of the left hand stile I 8, there is a keeper and latch bolt device 20, consisting of a planiiorm body plate 1939, serial No.' 266,168

2|, of suitable sheet metal having two integral right angle anges 22 and 23, at the left hand side, formed on the left hand extreme'vertical edge portion of the plate 20 and being planiform and alinedwith each other in the same plane, and both spaced from the face of the stop I3 with clearance for a lever, and to be described. The mutually adjacent end edges of these flanges stop short of each other, the intervening material being removed, so as to form a lock slot 24 extending horizontally ,beneath the two flanges from adjacent the plate 2l. The mutually adjacent edges of the anges 22 and 23 are divergent at their outer parts, forming an enarged entrance to the slot 24. On the inner face of the stop I3 at a suitable height, there is swingingly mounted a stop and lock plate or lever 25, which is in the form of a iiat plate having an apertured upper end, in which there is engaged a shouldered pintle screw 26 engaged loosely in the aperture so that the lever may move loosely on its pivot, so that gravity tends to keep the lever in pendant position. The lower end of the lever is formed with a right angle inturned arm or flange 2l, adapted to enter the slot 24 by swinging movement of the lever 25 when the keeper 20 is at the proper level, the lever being pivoted close enough to the channel I5 to permit. the lever to swing readily to p-Csition with the flange 2'Ifully engaged in the slot 24. The

ange 21 is formed with a large aperture 28 therethrough to receive therein the lower end of the bolt element 29 slidably mounted on the inner side of the upper flange 23.

, The bolt 29 is a flat elongated plate having a finger piece 3|] at the upper end consisting of the end portion of the plate inturned at right angles, and below this in the vertical paniform body of the plate there is formed a short longitudinal slot 3 I through which a headed pin 32 is extended and set in the 'flange 23 so as to hold the bolt flat against the flange 23 and freely slidable to the limits determined by the length of the slot 3l. One longitudinal edge of the body of the bolt is positioned close to the plate 2l, so that the bolt is held in close parallel and slidable -engaged relation thereto. The lower end of the bolt is form-ed with a bill or latch extension 33, the edge of which, away from the sash is cut on such an incline that when the ange 2l is pressed thereagainst, the bo't will be caused to yield and slide longitudinally upward. The pin is so positioned that when the bolt is at its lower limit of movement on the pin the bill 33 projects across the slot 24. The bill is relieved not obstruct movement of the bill downward in the opening 28, and also to aord a vertical keeper edge which will prevent outward movement of the flange 21 from the slot 24 when the bill is engaged therewith.

In use, the keeper and bolt device is secured to the inner face of the sash a distance below the upper rail ll', and spaced from the stop I3 a suieient distance to afford a Clearance for the lever 25 and its pivot screw 26. The sash is then lowered to its full movement, and the lever 25 positioned against the stop la with its fiange 21 a short distance above the top edge of the flange 23, the flange being in the relative positions as dotted at A, in Figure l, or with the flange 21 engaged in the slot 24, as shown in full lines in Figure l. The position of the lever 25 is then marked and the sash moved so that the screw 2,6 may be put in place to hold the lever at vthe position marked.. With the lever 25 mounted as shown in solid lines in Figure l, and the'sash inv iull lowered position, it will 'be seen if that the sash not be raised until the bolt 29 is raised and the lever 25 swung away from the slot' 2t. While the bolt isengaged, it will be apparent that it will be practically impossible to release the sash from outside the window so that it may be raised for burglarious purposes.

The sash may be raised and similarly locked in partly raised position with an opening the vertical dimension of which will be equal totwice the radius of the lever 25, by releasing and disengaging the lever 25, then raising the window the approximate distance necessary and swinging the lever to its upper limit bringing the slot 24 into'alinement with the flange 21 at this position of the lever, and pressing the flange 2l into the slot. This will lift the bolt as indicated, and they latter will drop or may be pressed downward to engage the bill 33 in the opening 278 by pushing on top of the linger piece 3l). Should it be desired to support the sash in full raised` position by means of the lever 25, the lever 25 is disengaged from the slot 2li and the sash raised slightly above the position of the lever 25 when inverted, and then, while the lever is positioned as shown in Figure 5, the sash is lowered until it rests upon the outer face of the flange 2'?, as shown inA Figure 5.

If the placement of the parts on the window is effected with the keeper device 2o entirely below the lever 25 as indicated at A in Figure l, two partially raised positionslof the sash with the sash securely locked at either position, are possible. Thus, with the flange 21 over the flange 23, raising of the window will be prevented by the engagement of the upper edge of the flange 23 against the flange (although the bolt 2S will not then be effective to hold the lever 25, in position). The sash may then be raised slightly and secured by moving the lever 25 to disengaged position and raisingrthe sash just sufficiently for the flange 2 to enter the slot 24, then pressing the fiange 21 into locked relation with the bolt 25. The opening thus secured will be slightly wider than the radius of the lever 25.

The sash may be adjusted further from the last named position and locked by disengaging the lever 25, swinging it to inverted position and raising the sash the slight further distance necessary to permit the flange 21 to again enter the slot 24 with the lever in its raised position, then again pressing the flange 21 into locked engagement with the bolt 29.

If desired, two or more levers or stops 25 may be secured on the frame at different levels, which may be utilized alternately in engagement with the keeper assembly.

It will be noted that the lower edge of the lower flange 22 is inclined, and this insures that when the sash is vto be lowered the lever can not impede the passage of the keeper device, but the inclined edge will fend or deflect the lever 25 inward away from the sash and cause it to swing out of'the path of the keeper assembly as the latter moves,"by wiping engagement of the inclined edge off thel flange 22 against the inner edge of the flange 21. The inclined outer part of the lower edge of the ange 23, forming the enlargement of the slot 24 will also serve a similar function, preventing the ange 21 from' being accidentally engaged in the slot 24 when the sash is being lowered.

I do not regard the invention as limited to the specific construction of the invention shown, and various changes in such structure may be made without departing from the spirit of the invention as set forth more particularly in the appended claims, wherein I claim:

i. A sash stop and lock consisting of a keeper part formed of sheet metal having a planiform base body adapted to be secured against the face of a sash, and having ilange portionsat one edge adapted to lie beside a window frame and having an intermediate horizontal slot therein, a plate slidingly secured to said keeper and having a boit portion arranged to project across said slot at one limit of movement and being retractable therefrom, and, a lever part constructed to be pivoted on av frame element and having a transverse ilange having opposite edge portions adapted to enter said slot respectively at pendant and inverted positions of the lever, and said flange being apertured to receive said bolt portion therethrough when the ange is engaged in the slot.

2. The structure of lclaim 1 including a frame member and a shank' member, the keeper being secured to one and the lever on the other, the frame having a sill, said parts being secured to the respective members in one window locking position with the sash at its lower limit of movement, said lever being in position to be released, inverted and reengaged with said keeper slot at an open position of the sash.
