PATENT OFFICE.
CHARLES HEARNSHAW, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 77 5,602, dated November 22, 1904.
l Application filed March 14, 1904. Serial No. 197,917. (No model.)
To all whom, it may con/007%:
Be it known that I, CHARLES HEARNSHAW, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, h-ave invented certainV .of the sash-lock, all as will hereinafter more fully appear, and be more particularly pointed out in the claims.
In the accompanying drawings, illustrative of the present invention, Figure 1 is a plan view of the present sash-lock, showing the parts in a locked position in full lines and in an unlocked position in dotted lines. Fig. 2 is an elevation of the same with the meetingrails of the sash in transverse section. Fig. 3 is a transverse sectional elevation of the same at line Fig. 1. Fig. 4 is a bottom plan of the spring-catch member of the sashlock. Fig. 5 is a detail perspective view of the keeper member. Fig. 6 is a like view of the spring-catch member.
Similar numerals of reference indicate like parts in the several views. y
Referring to the drawings, 1 represents the base-plate of the spring-catch member of the sash-lock, adapted for attachment to one of the meeting-railsof the sash and recessed out on its under side to form a chamber in which is arranged the actuating-spring of the spring dog or lever hereinafter described.
2 is a horizontally-swinging catch arm or lever pivoted to the base 1 by a pivot screw or stud 3, and 4 is a spring arranged in the pivot-hub of said lever and around the pivotscrew 3, with its free end adapted to yieldingly force the catch-arm into its engaging position.
5 is a stop-lug on the base 1 for limiting the retraction of the catch-lever 2.
6 is a thumb lug or projection on the catchlever 2 for the convenient manipulation of the same by hand.
7 is an upturned finger on the free end of the catch-lever 2 for engagement withthe curved back of the hereinafter-described horn of the keeper member of the sash-lock.
8 is a latch dog or lever pivoted to a longitudinal edge of the base-plate 1 and formed at one end with a detent 9 for engagement with the catch-lever 2 to hold the same in a retracted or unlocked position and at the other end with a projecting toe 10, that is adapted for operation by the keeper or the meetingrail carrying the same to release the detent 9 from engagement with the latch-lever 2 and permit its operating-spring to automatically swing said latch-lever into locking engage /vided with avertical post 13, carrying a horizontal horn 14 in separated relation, to the base-plate.12,as shown. Such projects wholly to one side of the post 18 and has a curved ba'ck 115,7the curve ofy which is eccentric to the pivot-axis of the catch-leverQ, so that with the movementof the linger 6 of said catch-lever against such curved surface the tendency will be to draw the meeting-rails of the sash together to exclude wind and prevent a rattling of the sash. The under surface of the horn 14 is curved upward near its free end, so that the end of the catch-lever 2 will freely pass under the same and in the movement of the catch-lever to a fully-engaged position. The said lever pressing against said upwardly-curved surface will tend to draw the sash into a fully closed condition.
IOO
16 is aprojectingledge on a horizontal edge of the base-plate 12, adapted to form an abutment forthe heretofore-described toe 10 of the latch lever or dog 8.
In the operation of the present sash-lock the operator will retract the catch-lever 2 by hand and maintain such lever in such retracted position While the sashes are moved apart a suficient distance to release the latch-dog 8 and permit the detent 9 thereof to rise in the path of and engage with said catch-lever to hold the same in its retracted position during the period that the: sashes remain separated. In closing the sash the operation will be automatic, in that as soon as the toe 1()` strikes the abutment-ledge 16 the detent 9 Will be drawn out of the path of the catch-lever to allovvthesame to move into engagement With the horn 14 of the keeper under the stress of the spring 4.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is
1. A sash-lock, comprising a base-plate, a spring-impelled catch-lever pivoted to said base and having movement in a horizontal plane, a latch-lever pivoted to a longitudinal spring-impelled catch-lever pivoted to said base and having movement in a horizontal plane, a latch-lever pivoted to a longitudinal edge of said base-plate and having an operating-toe at one end and a detent at the other end adapted to engage the catch-lever and hold it in a retracted position, a keeper-plate having a horizontal horn adapted for engagement with the catch-lever, and a ledge on the keeper-plate in line with the toe aforesaid and adapted to operate the same to release the catch-lever, vfor the purpose set forth.
Signed at Chicago, Illinois, this 9th day ofV March, 1904.
