JOHN JACKSON, OF CLINTON, IO\VA.
SASH- LOCK.
SPECIFICATION forming part of Letters Patent No. 385,935, dated July 10, 1858,
Application filed April 9, 1888.
To aZZ whom it may concern:
Be it known that 1, JOHN JACKSON, a citizen of the United States, residing at Clinton, in the county of Clinton, State of Iowa, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, reference being had therein to the ac companying drawings.
This invention relates to sash-locks, and among the objects in View are to provide an automatic lock which shall consist of as few parts as possible, thatis simple in construction, cheap,and readily applied to the meetingrails of a sash.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.
Referring to the drawings, Figure 1 is a perspective of two meeting-rails of a sash having a lock constructed in accordance with my invention applied thereto. Fig. 2 is a vertical section showing the lock in aclosed or locked position. Fig. 3 is a similar view, the lock being shown in a reverse or unlocked position, as in the act of raising the window.
Like-numerals indicate like parts in all the figures of the drawings.
1 and 2 represent, respectively, the meetingrails of the upper and lower sashes of a window, the latter rail having the usual beveled rear face. which is centrally and transversely recessed, as at 3, and provided with a tripplate, 3*, extending across the top thereof.
4 represents the loclrcase or housing, from the side walls of which there extendlaterally securing-plate 4*, and there may also be provided a transverse depending plate, 5, at the front of the case,which is designed to be seated in a recess formed in the front face of the upper meeting-rail, 1. The plates 4* and 5 are perforated, and adapted to be held securely in position upon the meeting-rail 1 by screws, as 6, passing therethrough.
Mounted upon a transverse shaft, 7, journaled in the sides of the casing 4., is thelock S, which is formed with the locking end 9, terminating in the angular shoulder or lug 10, and with the curved face 11 back of its locking end, terminating in a shoulder, 12.
Serial No. 270,100. (No model.)
In rear of thepivoted swinginglatch or lock 8 is pivoted a locking-pawl, 13, the same being mounted upon atransverse shaft,14, journaled in the opposite side walls of the casing and formed with the rear lug, 15, and shoulder 16.
Taking the lock as shown in Fig. 2, in order to raise the lower sash or lower the upper sash, the pawl 13 is first raised to a vertical position, thereby throwing out of contact its shoulder 16 with lug 12 of the lock. Then upon raising the lower sash or lowering the upper sash the parts arrive at the position shown by dotted lines in Fig. 2, lug 12 of the lock striking lug 15 of the pawl 13. By a further movement of either sash the lug 13 falls to a horizontal position by reason of thelug 12 comingagainst lug 15, and the pawl 1.3 rides over the curved surface 11 of the lock and rests against the shoulder 17, formed on the rear face of the locking end 9 thereof, and in this position the parts remain until the window is closed, the shoulder or lug 1O projecting out into the path of the tripping-plate on top of thelower meeting-rail. As the window closes, the trip-plate comes in contact with the shoulder 10 of the lock 8 and throws the same to the front, so as to rest upon the upper surface of the trip-plate. In this forward swinging or throwing of the lock 8 the pawl 13 rides over the curved surface of the same and takes in rear of the shoulder 12 thereof, thus preventing the moving of either sash until the pawl is lifted by the hand of the operator from position,when the operation described is repeated, and the operator is free to employ both hands, if required, to raise or lower the sashes.
Having described my invention and its operation, what I claim is- 1. The combi nat-ion,with the upperand lower meeting-rails of a sash, of asash-lock mounted on the former, the same consisting of a lockeasc having a pivoted swinging lock adapted to take over the lower meeting-rail and aprojecting lug arranged to be struck thereby and formed with a shoulder at its opposite end, and a pawl adapted to take against the shoulder when the sash is closed and to be operated thereby when opened, substantially as specificd.
2. The combination,with the meeting-rail 1,
the casing 4:,provided with the securing-flanges In testimony whereof I affix my signature in 4* and 5, the lock 8, mounted on the shaft 7 presence of two witnesses, in said casing and formed with the lockingface 9, and shoulders 10, 12, and 16, and the JOHN JACKSON. 5 pawl 13, mounted in rear of the lock and formed with the opposite shoulders, 15 and Witnesses: 17, of the recessed rail 2, having the trip 3, all 0. W. CHASE, combiped and arranged to operate as specified. J. H. WALLIKER.
