SASH-LOCK.
Specification of Letters Patent.
Patented Dec. 17', 1907.
Application filed May 24. 1907. Serial No. 375.490.
[0 all whom it may concern:
Be it known that I, FAYETTE SALTER, a citizen of the United States, residing at Atlanta, in the county of Fulton and-State of Georgia, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, reference being had therein to the accompanying drawm My invention relates to improvements in looking devices for window sashes, window shutters, doors and the like.
The object of the invention is to provide a simple, practical and inexpensive sash look by means of which both the upper and lower window sashes may be effectively secured in either their closed or partially open position.
A further object of the invention is to provide 'a locking device of this character which will be entirely burglar proof and which can only be unlocked by the use of a key.
TVith the above and other objects in view the invention consists in the novel construction and the combination of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which Figure 1 is an elevation of one side of a window frame with parts broken away and in section to illustrate my improved sash lock; Fig. 2 is an enlarged horizontal section taken on the plane indicated by the line 22 in Fig. 1 Fig. 3 is a vertical section on the plane indicated by the line 33 in Fig. 2; Figs. 4 and 5 are perspective views of the two sections of the bolt. casing; Fig. 6 is a similar view of the sliding bolt; Fig. 7 is a perspective of the bolt operating shaft and the lock for the same; Fig. 8 is a longitudinal section through the lock casing; Fig. 9 is a perspective of the bolt operating and locking shaft; Fig. 10 is a horizontal longitudinal section through the parts shown in Fig. 7 Fig. 11. is a perspective view of the key; and Fig. 12 is a detail section through the key.
Referring to the drawings, 1 denotes one side of a window frame, 2 and 3 the upper and lower window sashes, 5 the parting strip between the sashes and 6, 7 the usual outer and inner guide strips.
My improved sash lock comprises a sliding bolt 8 arranged in the frame 1 at its center and provided at its outer end with two integral projections 9, 10 adapted to enter recesses 11, 12 formed respectively in the sashes 2, 3. TVhile any number of the keeper bent from single pieces of heavy sheet metal and they each have abutting side flanges 15 and at their outer end an apertured attaching flange 16 adapted to receive a screw or other fastening which retains such section in the recess in the window frame. The bottom section 14 has a flange 17 at its rear end which also closes the rear end of the top section 13 and serves as a stop for one end of a coil spring 18 which is provided for the purpose of projecting the bolt. Said spring, as clearly shown in Fig. 2, has its opposite end arranged in a seat or recess 19 formed in the rear end of the bolt. In the bottom of the casing section 14 is formed an opening 20 to expose a rack 21 formed upon the bottom of the bolt and the side flanges 15 of the section 14 are formed with apertured bearing ears 22 arranged at points opposite the opening 20.
The bearings 22 are provided for the reception of a gear 23 formed integral with and upon the inner end of a combined bolt operating and locking shaft 24. This shaft extends at right angles to the bolt and its toothed portion or gear 23 is adapted to mesh with the rack 21, as shown in Fig. 1. The forward or outer portion of the shaft is mounted for both rotary and sliding movement in a tubular guiding and-locking casing 26 which is set in a suitable recess formed in the front or outer portion of the frame 1, as clearly shown in Figs. 2"and 3.
The casing 26 is formed adjacent to its outer end, which projects beyond the window frame, with an integral attaching flange 27 apertured to receive screws or other fastenings by means of which the casing will be retained in the frame. The bore or opening in the casing 26 has a rear portion 28 corresponding in diameter to that of the shaft 24 which is uniform throughout, as seen in Fig. 9, and it has a front portion 29 of greater diameter so as to form an annular stop shoulder 30.
.sliding movement thereon.
Adjacent to the rear end of the casing 26 is a transverse slot 31 extending approximately half way around the same and having at its ends keeper seats or notches 32, 33. In the front or enlarged portion 29 of the bore of the casing 26 is formed an annular groove or seat 34 with which communicates the rear ends of two longitudinally extending grooves 35 arranged at diametrically opposite points and having their forward ends opening at the front of the casing. The shaft 24 has its front end cut away upon opposite sides to provide a rectangular tongue 36 and formed in it between its front end and its gear or pinion 23 are a transverse aperture 37 and a longitudinal slot 38. The aperture 37 is adapted to receive aremovable pin 39, one end of which projects into the slot 31 in the casing 26 and is adapted to be forced into engagement with either of the seats or notches 32, 33 by a coil spring 40 which surrounds the shaft 24 and is confined between the stop shoulder 30 and the inner end of a locking sleeve 4]. which surrounds the outer end of the shaft and has a limited This limited sliding movement of the sleeve is permitted by a cross pin 42 which projects through and slides in the slot 38 in the shaft and has its ends projecting through apertures in the sleeve and into the grooves 35.
Upon reference to Fig. 10 it will be seen that the engagement of the ends of the pin 42 with the grooves 35 will prevent said pin from being turned in the casing 26 until it is moved rearwardly so that its ends enter the annular groove 34, and since said pin cannot rotate or turn, the shaft will also be prevented from turning. It is therefore necessary to move the sleeve rearwardly before the shaft can be turned to cause its gear or pinion to actuate the bolt. It will also be noted that owing to the engagement of the pin 39 with one of the seats 32, 33, the shaft cannot be rotated until it is moved inwardly to bring the pin 39 into the slot 31. For the purpose of successively unlocking the sleeve and shaft and then rotating the latter to operate the bolt, I employ the key shown in Figs. 11 and 12. This key has an enlarged end or head provided with a transverse notch 43 to receive the projection or tongue 36 on the end of the shaft and the walls of said notch or recess are recessed. to provide two substantially semi-circular tongues or projections 44 which receive the end of the shaft between them and are adapted to engage the outer end of the sleeve 41 for the purpose of actuating the same.
To unlock the device it is necessary to insertthe key in the outer end of the lock casing 26 and first move it inwardly against the tension of the spring to successively move the locking sleeve and the shaft inwardly so that their locking pins 42, 39 may be rotated, and second, turn the key to rotate the shaft so that its gear or pinion will actuate the bolt.
From the foregoing description taken in connection with the accompanying drawings it is thought that the construction, use and advantages of the invention will be readily understood without a more extended explanation.
While I have shown and described my invention as a lock for window sashes, it will be understood that it may be attached. to any stationary frame or support and used for locking any movable part or element such, for instance, as a window shutter, a door or the like.
Having thus described my invention what I claim and desire to secure by Letters Patent is V 1. The combination with a frame and a movable element having keeper seats, of a bolt arranged in the frame and adapted to be engaged with the keeper seats in said elemerit, a shaft operatively connected to said bolt, and a locking member for said shaft spring actuated to an operative position and adapted tobe retracted to an inoperative position by a key, substantially as described.
