This inventiony relates'to a'window sash lock and is' designed primarily for use in connection with the sashes of casement windows, but it is to be understood that a sashv lock, in accordance with this invention, is to be employed in any connection for which it may be found applicable, and the invention` has for its object to' provide,in a` manner as hereinafter set forth, a lock of the class ref erred'to for locking the upper end of a easement sash tor provide a safeguard against storms and theft".
AffurtherV object of the invention is to provide, ina manner as hereinafter 4set forth, a lock of theclass referred to capable vof being installed relativeto a `easement window sash independent of and without interfering in any manner with the meansY generally employed at the'bottom of a casementlwindow foropening, closing` andlocking the latter;
Further objects`r of the invention are to provide, in'al manner as hereinafter set forth, a window sash lock which is simple in its construction and arrangement, strong, durable, compact, readily installed relative to aV window,'tl'oroughly eicient in its use, conveniently operated to lock or releasethe sash, andinexpensive to manufacture'.

herrero-the element II; YThe niemeer 2n""1ssiid f plate 29 provided with openings 3|] for the pas' sage of holdast devices 3| for anchoring member 28 to the side I5 of the frame a substantial distance below the keeper 3. The plate 29 carries a shaft 32 for a segmental gear 33 and is formed with an offset part 33a against which the gear rides. The plate 23, in proximity to its lower end, is formed with a pair of apertured spaced parallel ears 34 for rotatable shaft 35 having a worm 36 and a reduced squared end portion 31 upon which is secured, in laterally extended relation, a socket forming member 3'1a for detachably receiving a crank handle 38 employed for rotating the shaft 35 whereby the worm 35 meshing with gear 33 will shift the latter. The plate 29, near its lower end, is formed with a slot 3Ba to provide a clearance for the worm 35 to extend in whereby the gear 33 will seat against the offset part 331. The lower end of the shank 2i is pivotally connected, as at 3Q, to the gear 33. The arrangement is such that when shaft 35 is rotated in one direction, the bolt member 2U will be elevated and when shaft 35 is rotated in the opposite direction, the bolt member will be lowered.
The bolt member 29 is adapted to extend into the slot I3 of the keeper 3 to prevent the opening of the sash 2 and also to engage the keeper 3 for the purpose of providing a snug closing t for the sash 2 relative to the frame. The element Il coacts with the pin 25 for guiding the bolt member 20 during its upward and downward movement and also for swinging the bill 24 clear of the keeper 3, as well as for moving the bill 24 against an end wall of the slot I0 for the purpose of drawing the sash 2 in to make a snug ilt relative to the fra-me. The sash 2 is hinged to the frame as at 40.
With reference to Figure 4, which shows a modified form of lock, a Casement window is illustra-ted which includes a frame 4| and a pair of sashes 42, 43 which are suitably hinged to frame 4| and when in closed position, overlap. The
I front of the sash 43 overlaps the front of the sash 42 as indicated in dotted lines, Figure 4. Secured to the lower face of the top member 43 of the frame 4I is a combined guide and coupling element 44 of the same construction as the element I I. Secured to the top stile 45 of the sash 43 is a keeper element 46 of the same construction as the element 3. Slidably connected to the element 44 by the pin 41 is a bolt member 48 of the same construction as the element 20, with this exception, that that end of the member 48 which is not provided with a hook is torsionally twisted, as at 49. Secured to the inner face of the side 50 of the frame 4I is an operating mechanism 5I which is of the same construction as the operating mechanism 28. gear 52 of the mechanism 5l, as at 53, is an actuating bar 54 having its upper end torsionally twisted, as at 55.
Secured to the inner face of the side 5G of the 'frame 4I is a bracket 55 to which is pivotally connected, as at 55, a bell crank 51 having its arm 5B pivotally connected, as at 59, to the end 49 of member 48 and which has its other arm 60 pivoti ally connected, as at 6I, to the end portion 55 of -"actuating bar 54.
The member 48 operates relatively to 'the element 4S in the same manner as the member 28 operates with respect to the element 3.
The bolt member moves lengthwise with respect to the frame member I 5 or'frame member 42 and also transverselyin opposite directions with respect to the member I5 or 42 and this movement Pivotally connected to the segmental is accomplished by the operating mechanism in connection with the slot I9 in the element I I. When the bolt member interengages with the keeper element and with the bill of a bolt member arranged at the rear end wall of the slot in the keeper element, the sash or pair of sashes are locked from movement and with the locking arranged at the upper portion of such sash or sashes.
What I claim is:
i. In a window sash lock of that type including a keeper carried by a sash, the combination of a stationary combined guide and coupling element formed with an angle shaped slot, a shiftable bolt member having a part at one end adapted to extend into the keeper for locking the sash, means for slidably connecting that end of the bolt member provided with said part to said guide and coupling element to provide for the said end of the bolt member shifting in opposite directions relative to the keeper, and an operable means adapted to be secured to the window frame and pivotally 'connected with the other end of said bolt member for shifting said part into and out of the keeper.
2. In a window sash lock of that type including a keeper adapted to be carried by the sash, the combination of a manually operated shaft provided with a worm, a segmental gear meshing with and operated from said worm, supporting means adapted to be secured to a window frame for the said shaft and gear, a hook shaped bolt member adapted to engage in the keeper for latching the sash, a combined guide and coupling element adapted `to be secured to the window frame and having one end of the bolt member slidably connected thereto, said combined guide and coupling element having means for moving said bolt member in opposite directions relative to the keeper, and means for pivotally connecting the other end of said bolt member with said gear.
3. In a window sash lock a bolt member including a hook-part, a stem-part merging at one end into the inner end of the hook-part and an elongated shank-part merging at one end into the other end of and disposed obliquely to the said stem-part, a stationary inclined member formed with an angle-shaped slot and having one of its terminal portions opposing one face of said hookpart, means extended through said slot for slidably connecting said hook-part to said member, and a bolt member shifting means connected to the other end of the shank-part and coacting with the latter said slot and the said slidably connecting means for shifting the hook-part to and from locking position.
ll. In a window sash lock, a locking bolt including a hook-part, a stem-part having one end thereof terminating in the inner end of the hookpart and an elongated shank-part merging at one end into the other end of the stem-part, a stationary member formed with an angle-shaped slot and having an end terminal portion thereof opposing one face of the hook-part, means extending through said slot for slidably connecting said hook-part to said member, a manually operated shaft provided with a worm, a segmental gear meshing with and operated from said worm, supporting means for said shaft and gear, and means for pivotally connecting the other end of said shank to said gear.
