HARVEY LANE, or TOLEDO, OHIO.

AUTOMATIC sAsH-LocK To all whom it may concern: Be it known that I, HARvEY LANE, a citizen of the United States, residing at To-.

of the kind that is adapted to automatically.

lock both the upper and lower sashes 0f a window in any open, as well as 1n their normal closed positions, and that is readily and conveniently unlocked to admit of the movement of either sash, and that is readily accessible from the inside of the buildln C and 1s non-accessible from the outside for unlocking, whether the sash be locked open or shut. 7 .I accomplish these objectsby the construction and combination of parts as hereon line y-y of F ig.- 1, attached to a broken drawings, in which inafter described and illustrated in the Figure l is a side elevation of a lock structed in accordance with my invention, detached from a window frame.

window.

The base plate '1 hasintegral with and" Specification of Letters Patent.

1 perpendicular to its inner side the cylindrical lugs 3 and 4, each having integral therewith a pair of parallel walls 5 and 5, ex-

socket bores 6, extending through the outer face 7 of the plate 1, and, opposite the spaces 8 between the walls Sand 5, with the Patented Apr. 4,1916. 7 Application filed January 29, 1916. Serial No. 74,992.

rectangular transverse openings 9 alined with the spaces 8. The lug 3, andthe wall 5 of the lug 4:, each have integral therewith.

and with the base plate 1 anclat right angles thereto, a bearing wall 10. The bearing walls 10 are of equal length with the lugs 3 and l and, opposite the free end portions of the lugs, are provided with alined guide openings 11 for a purpose hereinafter describech In the inner end portions of the bores6'of the lugs 3 and 4 are inserted the helical 13, having the transverse openings 14 alined with the openings 9 ofthe lugs. Fig. 2' 1s a' longitudinal section of the same on line Between the wa'lls 5 and 5,0f each lug is pivotally mounted by'a' pin lo, a bell crank 16, each bell-crank having an arm'l7 extending into the opening 1 1' ofthe locking springs 12 and in the outer portions, bear- A ing'agalnst thespr1ngs,'are the locking bolts con- 7 bolt 13 of the next adjacent lug, and an arm.

18 extending at a right angleto the arm 17 between and beyond the walls5 and'5.

Through the guide .openingsll of thebearingwalls 10 is extended and movably mounted the push bar 19, which is provided with the push pins 20, which extendrespecf' tively at right angles from the bar trans-f versely over the walls 5 and 5" of each lug,

in engagement with the innerangle faces of the arms 18 of the bell cranks 16., The end portions 19 of, the push bar'19,

nearest the lug 3, is bent at right angles to themain bodyoof the bar, and is perforated and screw tapped to have threaded therein thefcylindrical extension 21-,having at its free end a flattened handle portion 2l,'and near the handle portion is provided "with a locking pin 22.".The extension 21 of the push bar extendstlirough a' plate 23, which is adapted to be secured to the inner face of a window frame 24, preferably inset therein ina suitable recess (not shown) to receive the plate. r 4. g h The base plate 1 is located (preferably at I the right side) of a window frame 25, (relative to ins'de of the room in which the frame is located), opposite the lapping portions of the upper and lower sashes of the window,

and in a recess 26 adapted=to-recei e the plate with its outer face 7 flush with the outer face f the side of the window frame,"

and transverse the slide ways of both the upper and lower sashes and their dividing strip 27. The recess 26 is provided opposite each sash with an extension recess 28 adapted to freely receive theilugs 3 and 4:,

the walls 5 and 5, andthe bearing walls 10,. with the bell cranks 16 and the push bar 19' freely movable therein, it being understood that the distance of projection of the lugs and working parts described, from the inner face of'the plate 1, is-not sufficient in any instance to extend them into the-travel :ways' of the sashweights, (not shown); Itisalso to be understood that the recess 28 is so located that the lug 3 is located opposite the" top portion of the lower sash 29, and the lug 4: opposite the lower portion of the upper sash 30.

In line with the'perforation of theangled end portion of the push bar 19 the inner portion of the window frame 25 is-provided with an orifice, (not shown), to receive the. extens on rod. 21 which has its inner end.

portion reduced and'threaded torun into the tapped end portion of the push bar 19.

The slide faces of the upper and lower sashes abutting the base plate 1 have recessed therein, flush therewith, the: lock. strips 31, which are provided with perforations 32 at regular short intervals of their lengths adapted to receive the reduced end portions 13 of the bolts 13, which-are normally projected by the springs 12'beyond the face 7 of the base plate 1, as shown in" Fig.2. The strips 31 may ext-end'any suitable distance along the slide faces of the sashes, but they need not extend beyond a distance which will admit locking the sashes V in open position at the top and bottom of the window for purposes of ventilation,

normally registers with the lock pin 22,

when the threaded end portions of the ex tension 21is run into and shouldered againstthe angled end portion of the push bar 19,

and in such pcsiton the extension 21 is free to be pushed inward until thepin-22 passes through the incut 23. However, if the extension 21 be turned a quarter turn to the left before pushing thereon, the pin 22 looks it against being pushed inward, or if the quarter turn ism-ade after the pin 22 of the extension is pushed through the incut of the plate 23, the extension 21 is locked against outward movement. Thus constructed it is manifest that when the exten-' sion 21 is in its normal unlocked position,

a push inward thereon will move the push bar 19 to move the bell cranks from their positions shown in Fig. 2 into the positions shown in Fig. 3, and thereby withdraw the bolts 13 within the lugs 3 and 4:, and that upon releasing the pressure on the extension Y 21 the springs12 automatically returns the bolts to their normal locking position, as shownin Fig. 2, as also the extens'on 21 to its normal position. It is also manifest that so long as the push bar is held pushed inward both sashes will be unlocked and either may be freely moved to open, and that in whatever position they are left when thepressure is removed they will be either locked, or will be automatically lockedwhen,

moved in either direction less than a full interval between the perforations 32 of the" Y strips 31, it being readily seen that the lock bolts 3 will be held pushed inward by the sash between the perforations if the push bar is relcasedwhile in such intermediate position, and that when thefsash is moved in either direction from such intermediate POSl- 7 tion, as soon as the nearest perforation is lnregister with either of the bolts 13,%the' springs 12 of the bolt will automatically move the bolt into locking engagement with the strip 31 of the sash.

Either of the sashes of a window,

equipped with a lock constructed as de: scribed, may be readily and independently moved from and to a normally closed 1105i": tion by hold ng the extension 21 pressed inward while the sash is being moved. Upon releasingthe extension both sashes will be locked in vwhatever relative position they When it is desired to lockthe bolts 13 in V unlocked position, so that the sash may be moved freely up and down for convenience of washingor cleaning, by first pushing the extension 21 inward to withdraw the bolts 13 1 7 from looking POSltlOIL and then giving the;

extension a quarter turn until the pin 22. is"

out of alinement with theslot '23, the bolts 13 are lockedin open position and the sash may then be moved freely'up' and down without either becoming locked; I

Equipped with my lock, the upper sash."

of a window may be lowered and the lower raised, each a distance insuflicientto permit a person from entering through the openings, and in suchposition the sash willbe as securely locked against further movement as in a closed position, and if the further precaution is taken to lock the extension 21 as described, the lock is secured against being unlocked from the outside, notwithstandand I therefore do not limit myself in its construction excepting as expressed in the claims.

What I claim to be new 1s- 1. In'an automatic sash lock, the combination with a window frame and upper and lower sash slidably mounted in the frame,

of a lock comprising a. base plate, recessed in the window frame transverse the slide ways of the upper and lower sashes, opposite the lapping portions of the upper and lower portions when in closed position, said base platehaving bolt housings and bearing supports projecting at right angles thereto from its inner face, one opposite each shde way, spring pressed bolts movable in the housings and held normally projected partly through the outer face of the base plate -into the slide ways, a bell crank for each bolt, said bell crank pivotally mounted in a support of the base plate and having one arm engaging and adapted to reciprocate the bolt in its housing, a push bar movable in guide ways of the base supports and adapted to engage the free arm of each bell crank when pushed in one direction, and move the bolts against the resistance of their springs,

and when released from pressure to be mowed in the opposite direction by the pressure of the springs on the bolts and the bell cranks, a push rod connected to the push bar and extending through the inner wall face of the window frame, and adapted to operate the push bar to unlock the bolts, and'lock plates secured to slide faces of the sashes, transverse the outer face of the base plate, said lcck plates having perforations at short intervals adapted tobe brought into register with and receive the lock bolts,
