specieatioriof Letters Patent Patented Mar.,25, 1913.
Application led July'l, 1912.v Serial No. 707,076;
Toull wit-,0m it may concern! Be it known that I, SAMUEL H. LACK- LAND, a citizen of the United States, and resident of St. Louis, Missouri, have invented certaimnew and useful Improvements in lVindow-Sash Locks, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.`
My invention relates toy improvements in window sash locks, and the object of my invention is 'to construct an`improved lock which will automatically lock the two sashes together, and to arrange the lock in such manner that the upper sash may be locked in a partially open condition in order to al'low for ventilation at the top ofthe window.
. Vith the above purposes in view my invention consists in certain novel features of construction and arrangement of -parts as will be hereinafter described, lpointed out in the claims and illustrated ingdrawings, in which- Figure 1 shows'in elevation a sashr lockconstructed according to my invention; and" Fig. 2 is a sectional elevation of a window equipped w-ithone of my improved locks. l Referring by numerals to the accompanying drawings: 3 designatesv the window frame, 4 the lower sash and 5 the upper sash, the frame and sash all being of common construction and forming' no part of my invention.
The numeral indicatesabracketwhich is secured to the top rail of the lower 'sash adjacent one of the jambs of the window frame. Formed integral with the bracket and projecting upwardly from the upper .face of the rail is a pair of vperforated ears 7, forming a support for a pivoted dog 8 arranged for engagement with a rack 9 secured to the stile of thel upper sash Projecting laterally and formed integral with the bracket 6 there is a bearing 10 for the upper end of a rod 11, the lowermost end of the rod 11 heilig held in va bearing 12. Formed integral with the rod 11 beneath the sheet metal, and integral therewith is a leaf spring 14 which bears againstjlhe arm for' purposes hereinafter more fully explained.
lAt'theupper endk of. the rod 11 there is a of the" dog.
by the accompanysash y metallic block 15 liaving'on one of its -faces is secured t'o the face of the jamb of the window frame adjacent its lower end.` Secured'to the bracket 6 between the ears 7 and the rack 9 is an elastic block 21.such as rub- Iber, which normally bears upwardly against tHe-dog 8 to' prevent t-he engagement of the dog with the rack 9.' In order toprovide forditfere/nt thicknesses of window sash there is formed in the dog 8 a number of holes 22, to permit of a shifting of the pivotal point As shown inthe drawings, the lock| is in a position holding both sa'shes fully closed. 4In this position the arm 13 is held in the slot 19; so that theY block 15 is raised to bear againstthe dog 8 and hold itin engagement wlth therack- Qagainstthe press-nre ofthe velastic block 21. The leaf spring 14, hold- 'lng' ythe' arm 13 within the slot 19, prevents the block 15 from being rotatedv so that the locking tooth- 17 will engage in the'te'ethl` of the block. It is to be observed that there is a number of the teeth 16 and the function of these teeth is'to provide an automatic adjustment which will take care of any vertical play of the sashesafter the lock has been-placed in position. If itwere not for such an adjustment, the ent-ire strap 18 wouldhaveto be moved vertically at times to take up this play.
The operation of'unlocking the device in order that either of the sashes may be moved is as follows. The arm 13 is turned laterally against the tension of the leaf spring 1l so that said arm will be freed from the slot 1f). This turning of the arm and theentire rod 11 turns the ratchet face of the block 15 out of engagement with the.
locking tooth. 17, whereupon the yblockr ,Y will be disengaged from the brackett and will drop a slight distance, thel block of 'elastic material 21 freeing the dog 8 from the rack 9. In this manner either sash may be freelyvmoved.
On account. of the length of therack 9 the upper sash 5 may be locked when the lower sash 4 is fully closed in a position leaving some considerable space between the tcp rail of the upperl sash and the upper part of the windoT frame in order to provide l ventilation at the top of the Window.
I claim:
l. In a window sash lock, a racksecured-to the stile ot the upper sash, a dog, a 'vertical rod rotatably carried Yby the lower sash, a toothed block carried by said rod in engagei nient with said dog, a right angled arm cari ried by the rod, a spring acting on said rod for rotating it in one direction, and means secured to the Window frame arranged to turn said rod in one direction against the tension of said spring and arranged t0 hold said rod against vertical movements.
2. The .improved Window sash lock, comprising a rack secured to the upper sash, adog secured to the lower sash and arranged to engage said rack, an elastic element normally acting on said dog to hold it out of engagement Wit-h the rack, a rod rotatably mounted upon the lower sash, a t-oothed block carried by the said rod in engagement l with said dog, a locking tooth carried by .the lower sash and arranged for engagementi with said toothed block, an arm carried by i said rod, a leaf spring acting on said arm for rotating it in one direction, and a strap il secured t-o the Window frame, arranged to l rotate the rod against thevtension of said leaf spring and also arranged to engage the arm and hold the rod against vertical 1novement.
3. In a window sash lock, a rack fixed to the stile of the upper sash, a dog pivotally secured to the rail of the lower sash and arranged for engagement with said rack, means for normally holding said dog out `of engagement with said rack, bearings carried by said lower sash, a rod rotatably mounted in said bearings and capable of movements vertically relative said bearings, a toot-hed block secured to rotate with said rod,` a locking tooth for engagement with said toothed block, a right angled arm carried by the end of the rod oppo-site said block, a spring for engagement with said armfor the rotation of said rod in one direction. and means secured to the Window frame for engagement with said arm for turning said rod in a direction, against the tension of said spring and for holding said arm against vertical movements.
In-testimony whereof, I have signed my to this specification, in presence of two subscribing Witnesses.
