Description

April 28, 1959 A. H. BAPTIST 2,884,276
/ SASH LOCK Filed March 14, 1957 States., Batent @nice aaatgzv sAsH Loox H. Baptist, Glenview, Ill.l z,1ssignor,tol Fred GranberrgA` Application Mal-c1114, 19,57., Serial No. 645,944
ZCl'alms. (Cl2`292`-336)' This invention relates to a sash lock and in particular to an improved, automatically operable window sash lock.
The instant invention comprehends improved means for effecting rotation of the latch plate of an automatically operable sash lock such as disclosed in the copending application of Fred Granberg, Serial No. 592,860, tiled J une 21, 1956, now Patent No. 2,846,258, issued August 5, 1958. The invention further comprehends the provision of new and improved means for mounting the latch pin mechanism of such a sash lock.
The principal feature of the invention is the provision of a sash lock having a new and improved spring biasing means for operation of the latch plate.
Another feature is that the spring biasing means comprises a support secured to the post on which the latch plate is carried having a radially outwardly opening annular groove and a coil spring at least partially received in the groove having one end secured to the support and its 'other end secured to a retaining means tixedly associated with the latch base.
Still another feature of the invention is the provision of a plate secured to the latch base by means of the post and having a bearing upset therefrom for journaling the latch pin.
A further feature is that the plate is further provided with an upset tab for retaining the other end of the coil spring.
Other features and advantages of this invention will be apparent from the following description taken in connection with the accompanying drawings wherein:
Fig. 1 is a top plan view of a sash lock embodying the invention;
Fig. 2 is a vertical section taken approximately along the line 2-2 of Fig. 1; and
Fig. 3 is a bottom plan view thereof.
In the exemplary embodiment of the invention as disclosed in the drawings a sash lock is shown to comprise a catch mounted on a window member 11 and a latch 12 mounted on a window member 13. Rotatably mounted on a latch base member 14 of the latch 12 is a latch plate 15. For a complete description of the structure of the latch base 14 and latch plate 15 and the functioning thereof relative to catch 10, reference may be had to the Granberg patent. The present invention relates to the means for controlling the latch plate, and the structure and functioning thereof is set forth here following.
Reference now being had more particularly to Figs. 2 and 3, the means for biasing latch plate 15 is seen to comprise a post 16 extending rotatably through a transverse portion 17 of the latch base. An outer end 18 of the post is xedly secured to the latch plate, and an inner end 19 is received within a space 20 defined by base portion 17, a peripheral ange 21 depending from portion 17, and window member 13.
Ends 18 and 19 may be radially enlarged to effect retention of the post on the latch base. Secured to inner end 19 is a cup member 22 having a mid-portion 23 of Ia ysubstantial the spring...l
One ,endl 26 ,of spring 25,l is, secured toAv the1 cupvmeruller.A
22 by means of a lug 27 struck from the cup member to extend adjacent its periphery thereby providing irnproved leverage of the action of spring 25 on post 16. The other end 28 of the spring is secured by retaining means, to be described in greater detail here following, to arrange that end of the spring substantially tangentially to wall 24 and cause the spring to urge latch plate 15 in one direction of rotation. To retain the spring properly around wall 24, the wall may be formed to provide an outwardly opening, annular groove 24a. The groove is preferably of sufficient depth to receive a substantial portion of the coil spring 25 therein, as best seen in Fig. 2 and thus cup member 22 comprises an improved support for spring 25, precluding undesired lateral movement thereof.
Associated with latch plate 15 is a trip pin 29 such as that disclosed in the Granberg patent. The instant invention comprehends the provision of new and improved means for journaling the pin 29. For this purpose, a plate 30 is disposed in facial juxtaposition to the lower surface of latch plate portion 17 so as to lie within space 20. A bearing 31 is struck from plate 30 in alignment with an opening 32 in the latch base 14, and pin 29 extends through the bearing for cooperation with a leading edge 15a of latch plate 15, which edge is moved across opening 32 during pivotal movement of the latch plate.
Also struck from the plate 30 are a tab 33 for holding one end of a biasing spring 34 associated with the latch pin and a tab 35 comprising the retaining means for spring end 28.
Plate 30 is secured in position under portion 17 of the latch base by means of post 16 which extends through an opening 36 in plate 30. The peripheral conliguration of plate 30 is made complementary to that of ange 21 of the latch base. Thus plate 30 may be held against movement away from portion 17 by means of post end 19 and against movement in its own plane by means of its abutment with tiange 21.
It may thus be seen that plate 30 may be simply and economically formed to comprise the means for retaining the free end of spring 25, the means for retaining the free end of spring 34, and the means for journaling pin 29. Further, the plate 30 may be readily and economically installed.
While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as defined in the appended claims.
I claim:
1. In a sash lock of the character described having a latch base, a latch plate, and a post through said base secured to said latch plate to secure pivotally said latch plate to said latch base, means for effecting approximately rotation of the latch plate, comprising: an annular support secured to said post; retaining means associated with said base and spaced substantially radially of said support; and a coil spring having an end secured to said support and another end secured to said retaining means to extend substantially straight between said retaining PitentedAprt A28,? .1 959;.ji
means and support aft one extreme of movement of the latch plate and at least partially around said support at the opposite extreme of movement of the latch plate, said spring acting to urge rotatably the latch plate toward said one extreme of movement.
2. In a sash lock of the character described having a latch base, a latch plate, and means pivotally securing said latch plate to said latch base, means effecting approximately 180 rotation of the latch plate, comprising:
a support xedly associated with said latch plate having a radially outwardly opening annular groove; a retaining means thereon associated with said base and spaced from said support a distance approximately equal to one-half the circumference `of the groove; and a coil spring having an end secured to said support and the other end secured to said retaining means to extend substantially straight" between said retaining means and support at one extreme of movement of the latch plate and to have approximately one-half of its length received in said groove at the opposite extreme of movement of the latch plate, said spring acting to urge the latch plate toward said one extreme of movement.
