A. L. BOUR BEAU AUTOMATIC WINDOW LATCH Fil ed March 23. 1921 Hex.

INVENTOR Patented 7, i923.

AUTOM'ATIG WINDOW IATGH.

Application filed March 23, 1921. Serial No. 45 L837.

To all whom it may concern:

Be it known that l, ALrnno L. Bonnanau, a citizen of the United States, residing at Lawrence, in the county of a: and in the State of Massacluisetts, have invented. a new and useful device in the form of an Autoinatic Window Latch, of which the following is a specification.

lvly invention relates to an automatic window latch that can be used in either tactory, house, or store vindows, enabling the user to ventilate the rooms where it is being used by opening the window 3 inches from the top and also 3 inches from the bottom and. still have the windows locked, the window may also be lei't opened from i to 6 inches from either top or bottom and still be locked in such a way that it cannot be tampered with, it requires no turning or Fastening as it automatically locks at every inch that it is lowered or raised, these are made in two sizes, namely, inch size is the most adaptable for stores and factories, and inch size in houses.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which: v

Fig. 1 is a detail view of that part of the invention called the rack.

Fig. 2 shows the device as applied to a pair of sliding sashes.

Fig. 3 is a detail. view of the latch mounting member, and

Fig. 4; is a detail View of the latch pawl.

As shown by Fig. 2 of the drawing 1 rep resents the lower and 2 the upper sash of a pair of sliding sashes mounted on the top rail of the lower sash is the latch supporting member 3, which consists of a base 4: and two parallel upstanding ears 5 and 6. Located in the top portion of the ears are two holes 7 and 8 to form a bearing for the latch pintle 9. Ihis supporting member or chair may be fastened to the top rail in any convenient manner, such as by screws. The latch 10 is tor-med substantially l.-sl1aped, having a long arm 11 and a short arm 12. Located at the junction of the two arms is the pintle receiving hole 18. The latch is mounted. between the ears of the support 3 by means of thepintle 9 and the registering apertures in the ears and the latch. Mount ed on the side rail of the upper sash is the rack bar 14, so arranged that the end 15 of the latch will engage under theedge of teeth l6 thereof. The latch will normally engage such teeth, due to gravity at the end of each of the steps 17.

It will be seen that as the lower window is raised and the top window lowered, the latch engaging the teeth at the predetermined distances, will prevent the windows from being moved further in the direction of open ing. The latch may be placed in inoperative position by pressing downwardly upon the short arm 12. Having described my invention, I claim.

A sash fastener, comprising a substantial ly L-shaped latch, the long arm of which has a pointed end, tl e short arm of which has a rounded end, means for receiving the pintle bearing located at the junction of the said short and long arms, a latch supporting member, including a base, two upstanding equally spaced parallel ears, between which said latch is adapted to be pivoted, a pintle extending through registering apertures in said ears and through the said pintle receiving means of the latch, a rack bar comprising spaced steps for engagement with the end of said latch.
