C. B. CLASEN Nov. 21, 1950 SASH LOCK Filed Dec. 26, 1947 Patented Nov. 21, 1950 UNITED "STATES PATENT, OFFICE 2,531,256
SASH LOCK Charles B. Clasen, Reno, Nev.
Application December 26, 1947, Serial No. 793,867
1 Claim.
This invention relates to window sash locks.
An object of this invention is to provide a sash lock for mounting on a pair of sash members which includes a pivoted bolt adapted to be secured to one of the sash members, and a keeper adapted to be secured to the other of the sash members, the keeper being formed with a horizontal slot having a flared mouth, so that engagement of the bolt in the slot will effect endwise movement of the sash members to tightly closed position.
A further object of this invention is to provide a sash lock which can be made out of metal, plastic or a combination of these elements.
A further object of this invention is to provide a sash lock which is of simple construction so that it can be formed out of cast or molded material.
To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawing:
Figure 1 is a plan view partly broken away of a sash lock constructed according to an embodiment of this invention.
Figure? is a sectional View taken on the line 2-2 of Figure 1.
Figure 3 is a sectional view taken on the line 3--3 of Figure 1.
Figure 4 is a sectional view taken on the line 4-4 of Figure 2.
Figure 5 is a detailed end elevation of the sash lock removed from the sash.
Referring to the drawing, the numeral l9 designates generally a block or base which is adapted to be secured by fastening means I l to the upper side of the lower rail l3 of an upper sash [2. The body or block is formed with a slot l4 extending horizontally through the inner edge of the block it] and also through one end thereof. The block it! on the lower side thereof has projecting therefrom a pair of tangs or points I which with the fastening means I l are adapted to hold the block In against movement on the rail IS.
A swingable bolt or bar IE is loosely disposed in the slot [4 being pivoted on the fastening member H. An inner block or keeper I1 is disposed on the upper side of the upper rail l8 of a lower sash 19. The inner block or keeper I1 is secured to the rail [8 by means of a screw 20 which has the head thereof countersunk in an opening 2| formed in the keeper H. The keeper i1 is formed with a horizontally disposed keeper slot 22 which extends entirely through the block I! and through one edge thereof. The slot 22 is flared upwardly as at 23 on one end of the block I1 and isalso flared downwardly as indicated at 24. The block ll is formed with an arcuate or cam shaped inner edge 25 so that when the bolt I6 is swung into the slot 22 the knob 26 which is fixed to the free end of the bolt l6 will bear against the curved inner edge 25 of the keeper block I1 so as to apply increased pressure between the two blocks l6 and I! as the bolt I6 is swung to substantially a right-angular and completely looking position.
The keeper block or body I! is also formed with a pair of downwardly projecting tangs 21 which are adapted to pierce the upper side of the rail I8 so that when the single screw 20 is in applied position the keeper block I! will be firmly held against turning movement with respect to the rail l8.
In the use of this sash lock the two members In and I! are secured by the fastening means H and 20 to the respective rails I3 and I8. When it is desired to raise or lower one of the sashes, the bolt I6 is swung to a position overlying the lower rail [3 of the upper sash I2. In locking the two sashes together these sashes are moved to their extreme upper and lower positions so that the upper sides of the rails l3 and i8 will be substantially coplanar. In the event there is a slight variation in the initial positioning of the windows including the rails l3 and [8 when the bolt 16 is swung to locking position this bolt will engage one of the flared surfaces 23 or 24 of the keeper block I! and further inward movement of the bolt It will effect vertical movement of the sashes one relative to the other and at the same time the rails 53 and I8 will by reason of the engagement of the knob 26 with the cam surface 25 be drawn tightly together.
I claim:
Ina sash lock a keeper block adapted to engage on the upper side of the upper rail of a lower sash, said keeper block having a horizontal keeper slot opening through the inner and outer edges and one end thereof, the walls of said slot being flared at said one end of said block for receiving and guiding a locking bolt slidably therein, a vertical bore extending through said block in the center thereof and intersecting said slot,
an upwardly opening counterbore of increased diameter formed in said block concentric with said first bore and extending below said slot, and a plurality of spaced apart tangs depending from the bottom of said block for engagement in the upper rail whereby a single headed fastening means may be disposed in said bore and counterhore for securing said block to the upper rail and said tangs will prevent turning of said block about the fastening means.
CHARLES B. CLASEN.
