INTER HENRY c. Donn, or MILWAUKEE, WISCONSIN.
SASI-I-LOCK.
Specification of Letters Patent.
Patented Dec. 31, 1918.
Application filed March 8, 1918. Serial No. 221,291.
Be it known that I, HENRY 0. Dean, a citizen of the United Statea'and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Sash- Locks; and I do hereby declare that the following is a full, clear, andexact description thereof.
The principal objectof this invention is to provide a very simply constructed sash lock which, when thrown to an active position will positively prevent movement of either of the sashes of the window in either direction. A secondary object is to provide a lock comprising a swinging arm to be moved into engagement with a sash of a window and having means for preventing the movement of the arm in one direction after it has been adjusted.
With these several objects in view the invention resides more particularly in the novel combination and arrangement of parts which will be hereinafter more particularly described and claimed.
In the accompanying drawing Figure 1 represents a vertical sectional view through inner end portions of a pair of sliding sashes, the improved lock being carried by one of said sashes and engaging the other, and Fig. 2 a transverse horizontal section taken substantially on the plane of the line 2-2 of Fig. 1.
Referring more particularly to the figures of the drawing, wherein similar reference characters denote like parts, the numerals 1 and 2 designate respectively the upper and lower sliding sashes of a window, the invention being mounted upon the upper rail 3 of the lower s ash 2 and engaging the side of the upper sash. The invention comprises broadly an attaching plate, a swinging arm pivoted thereto to be moved into engagement with one of the sashes, and a keeper for holding the arm in an adjusted position.
The attaching plate designated by the numeral 4: is secured to the top face of the rail 3 by means of the fastening screws 5 and 6, the last mentioned screw being extended through an opening formed in a depending portion 7 of the plate. This plate is preferably formed of sheet metal and has a pair of spaced apart ears 8 formed by bending the opposite sides of the plate upwardly.
These ears are provided with alined openings to receive a pivot pin 9 upon which a swinging arm 10 is pivoted. This arm is adapted to move toward the upper sashes 1 and is mounted as shown in the drawing, although it is obvious that the attaching plate might be screwed to any suitable support adjacent the sliding sash, depending upon the type of window with which it is to be used. The active end of the arm 10 carries a head 11 in which is formed a recess to receive a gripping plate 12 of rubber or similar material, the walls of said opening being under-cut to effectively hold plate 12 in position.
When the swinging arm 10 is inactive it is disposed as shown in dotted lines in Fig. 1, its active position being indicated in full lines. It is held in either of these positions by means of a substantially V-shaped leaf spring 13 of a width substantially equal to the distance between the ears 8 and disposed therebetween. One end of the spring is bent laterally and extended into a slit 14 formed in the attaching plate 4 between the ears thereof. The apex of the spring 13 extends toward the sash 1, and the free end of the upper arm 15 thereof engages either of the right-angularly disposed faces 16 and 16 formed on the arm 10 at the pivot end thereof. When said arm is in its inactive position the face 16 is engaged by the spring, the tension of said spring being sufficient to readily hold the arm in this position until it is manually moved to an active position.
Experience has indicated that in some instances the spring is not sufliciently strong to hold the arm in its active position, therefore, I have devised and formed a keeper for aiding the spring in holding said arm into engagement with the sliding sash. This keeper is in effect a lock for reventing movement of the arm in one direction, and it consists of a substantially U-shaped yoke 17 the arms of which straddle the swinging arm 10 and the ears 8. The free ends of the arms of this keeper are bent laterally inward to form pintles 18 by which it may be pivoted to the ears 8, said ears having openings 19 to receive said pintles. The cross bar of the keeper is adapted to engage any one of a number of ratchet teeth 20 formed on the upper edge of the arm 10 when said arm. isin its active position. V The position of the openings 19 and the shape of the spring 13 is such that the upper portion of the spring adjacent its apex will continuously engage the pintles 18 andtend to force the cross-bar of the keeper into engagement with the ratchet teeth. Thus after the swinging arm has been moved into engagement with the liding sash, the: keeper will move in the same direction and contact with one of the ratchet teeth. 7 It can be readily seen from Fig. 1 that when the-arm 10 andthe keeper are so engaged it will be impossible to return said arm to its dotted line: position. As the keeper is moved out of: engagement with the ratchet teeth: the arm 10 may be swung into an inactive position and held in this position bythe spring 13. Theprovision of a number of ratchet teeth permit the device to be used on sashes having rails of various widths, and this arrangement will also allow the sliding sash to be clamped more or less tightly.
' From the foregoing description taken in connection with the accompanying drawing it will be readily evident that I have invented a very simply constructed, and extremely efii'cient' sash lock which maybe used in connection with practically any sliding window sashto positively; holdasame in various adjusted positions. Because of the simple nature of the several parts of the device the same may-be very" inexpensively manufactured.
