HAROLD E. WILKINSON, OF CHELSEA, IOWA.
AUTOMATIC SASIL-LOCK.
Specication of Letters Patent.
Patented Apr. 1, 1916.
Application filed April 14, 1915. Serial No. 21,336.
To all 'whom t may concern Be it known that I, HAROLD E. WILKIN- soN, a citizen of the United States, residing at Chelsea, in the county of Tama and State of Iowa, have invented a new and useful Automatic Sash-Lock, of which the following is a specification. f
The device forming the subject matter of this application is adapted to be employed for locking together automatically, the cross rails of a pair of sashes, and it is the object of the invention to improve the construction of the latch whereby the sashes are locked, to improve the construction of the trigger whereby the latch is held in a retracted position and to improve the means whereby a proper working relation between the latch and the trigger is brought about.
I t is within the province ofthe disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.
With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying shows the invention in top plan, the latch being in set condition; Fig. 2 is a front elevation; Fig. 3 is a vertical section.
In the drawings the numeral 1 indicates the top rail of a lower sash and the numeral 2 indicates the bottom rail of an upper sash. Mounted upon the upper face of the top rail of the lower sash is a support 3 having depending ears 4 secured to one vertical face of the top rail 1 by means of attaching elements 5. Adjacent one end, the support 3 is provided with an upstanding boss 6 carrying a stud 7 holding a washer 8. Threaded onto the stud 7 is a wing nut 9 or the like. The opposite end of the support 3 terminates in an angularly disposed arm 10 eX- tending above the upper edge of the top rail 1 of the lower sash and terminated in a forwardly presented, overhanging finger 11. In the support 3 is fashioned a transverse opening 12 across which extends a pivot element 14.
The invention contemplates the use of a drawing: Figure 1i latch in the form of a bar or rod mounted support 3. In one edge of the latch 15 adjacent one end thereof there is formed a notch 1 6, the other end of the latch terminatlng in an angularly disposed arm 21 carrymg a lug 17. At the angle deiined by the arm 21 and the body portion of the latch there is formed a notch or seat 22. Intermediate its ends, the body portion of the latch is provided with an upstanding piece18 whereby the latchmay be manipulated. A helical compression spring 19 is engaged at one end by the finger 11 of the support 3 and at its other end is the lug 17 on the latch 15.
The invention comprises a trigger 23 eX- tended through the opening 12 in the support 3j The trigger 23 is provided with an opening 24 through which the pivot element lt passes, the opening being large enough so as to give the trigger a `free vertical movement on the Vpivot element 14 within limits dened by the size of the opening 12 in the support 3. At one end, the trigger 23 terminates in an upstanding finger 25 adapted Enger 'to swing horizontally on the stud 7 of the engaged by v to coperate with the notch or seat 22 in the y latch l5, in a manner to be pointed out hereinafter. That end of the trigger 23 which is disposed above the botto rail 2 of the upper sash is provided with a depending weight 26 preferably formed integrally with the trigger. i
The Lipper surface of the bottom rail 2 of the upper sash carries a keeper 27 comprising a base 28 and a standard 29 having a notch 30 adapted to coperate with the notch 16 in the latch 15, the base 28 of the keeper being attached to the bottom rail 2 of the upper sash by means of securing elements 3l.
When the sashes are closed, the notch 16 in the latch l5 is engaged with the notch 30 of the keeper 27 and thus the sashes are locked together. At the same time, the weight 26 on the trigger 23 is engaged by the bottom rail 2 of the upper sash, the trigger being tilted so that the finger 25 on the trigger is out of engagement with the notch 22 in the latch 15, as will be understood from the dotted line showing of Fig. 3.
To dispose the mechanism in set condition, the latch 15 is swung by means of the linger piece 18 from the dotted line position of Fig. V1 to the solid line position thereof. This operation disengages the latch 15 from the trigger will swing vertically, the nger 25 on the trigger engaging inthe notch 22 of the latch 15 and being held in that 4position by the action of the spring 19. lf the upper sash is moved upwardly, or if the lower sash is moved downwardly untilthe rails l and 2 are in horizontal alinement, the rail 2'of ythe upper sash will engage the weight 260i the trigger 23 and tilt the latter vertically disengaging the linger 25 from the-notch 22 in the latch l5. Thereuponlthe` latch 15 undervthe action `of the spring 19 will swingl from the Vsolid line position. of
Fig. l to the `dotted line position thereof and will interlock with the keeper 27'.
Havingthus described the invention, what is claimed lis:-
Inra sash lock, the combination with iupper and lower sash rails, of a keeper secured l to thecross rail of the upper sash; a latchVV v pivoted intermediate its ends to the cross rail of `the lowerssash to swing horizontally and: to engage at one end with the keeper,` the latch being provided adjacent its otherend with a notch; a rigid one-piece trigger ulcrumed intermediate its ends on the cross rail of the lower sash for tilting movement as an entity in a vertical plane, the inner end of the trigger terminating ina rigid upstanding finger adapted to engage in ther notch to hold the latch kretracted with respect to the keeper, the outer end ont the trig-V ger being adapted to be engaged. by :the cross rail of the upper sashto tilt the trigger and to withdraw the finger from the notch; Aand spring means coacting with'the latch to cause the same to coact with the keepen Inf testimony that l `claim the foregoing as my own, I have hereto laiixed mysignaturein the presence of two witnesses.`
