\VILLIAM OHISHOLM, OF ALLEGHENY, PENNSYLVANIA.
SASH-LOCK.
SPECIFICATION forming part of Letters Patent No. 391,119, dated October J 6, 1888.
Application filed February 27, 1858. Serial No. 265,453. (No model.)
To all whom it may concern:
Be it known that 1, W ILLIAM CHISHOLM, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Sash-Locks; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification, in Which Figure 1 is a perspective view of one of my improved sash-locks, showing it as it is when locking the window'sashes together. Fig. 2 is a front view of the lock when closed. Fig. 3 is a plan view of the lock, the stile of the upper window-sash being shown in horizontal crosssection.
Like symbols of reference indicate like parts in each.
In the drawings, 2 is the rail of the lower sash. 3 is the rail of the upper sash, and 4 is the stile of the upper sash. The sash-lock is arranged at the end of the meeting-rails and consists of a plate, 5,which is hinged on a vertical pivot to the face of the stile 4 and is arranged so that it may be swung on its pivot outwardly over the top of the rail 2 for the purpose of holding the sashes together, as shown in Figs. 1 and 3. This plate 5 is preferably hinged to the stile4 by means of a plate, 6, which is screwed into a recess in the face of the stile i, and has a projecting curved tongue, '7, which fits around a pintle on the hinged plate 5. On the surface of the rail 2 of the lower sash is a plate, 8, whose outer edge is curved in form and is somewhat eccentric to the pivot of the plate 5. At the bottom of the outer edge of this plate 5is a tongue or rib, 9, which,when the plate 5 is thrown open,travels in contact with the curved face ofthe plate 8, and by reason of the eccentricity of the latter draws the meeting rails of the two sashes together, as shown in Fig. 1. For neatness of finish and for the purpose of giving greaterstrength to the locking plate I prefer to make the flange 9 along the entire vertical outer edge of the plate 5 and to constructthe plate 6 with a concave outer face within which the plate 5 may fit when it is swung back toward the stile 4 and closed, as shown in Fig. 2. Vhen it is thus closed, it is entirely removed out of the path of the lower sash. It takes up but little room and does not disfigure the appearance of the window. The concavity of the plate above referred to is constituted by horizontal flanges at the top and bottom. Of these the top flange is the important one, because it fits against the top of the recess in which the baseplate 6 is set, and thus causes any strain put on the lock to be distributed and transferred to the upper sash. When the sashes are closed, the locking-plate 5 is easily opened tolock them, and when they are locked the sashes are held together with such security that it is practically impossible to force them open by means of a jimmy or other like instrument without breaking the sash itself to pieces. I prefer to have one of these locks at each end of the meeting-rails. If desired, there may be onlyasingle lock, arranged either on the stile or on the middle vertical rail of the windowsash frame.
The advantages of my improvement will be appreciated by those who are familiar With the insecurity and the uncouth appearance of the sash-locks now in common use.
My lock is simple, cheap, ornamental, and affords the greatest possible security against the entrance of burglars. If it be attempted to force up the lowersash by means ofajimmy, the strain comes upon the plate 5 at a point very close to its hinge-connection with the plate 6, and this plate 6 being set in a recess in the face of the stile 4 the -force is transferred directly onto the frame of the sash itself. The lock therefore cannot be separated or broken merely by a force sufficient to start the screws which hold its parts to the sash.
The lock may be modified in form and arrangement without departing from the principlesof my invention.
I am aware that in a prior patent, No. 184,036, there is shown and described a sashlock consisting of a vertical plate hinged on a vertical pivot to the side of an upright of the upper sash, on which pivot it is movable over the meeting-rail of the lower sash. I therefore do not claim this. My invention differs therefrom in that the base-plate of my hinged locking-plate and its pintle are set in a recess in the face of the stile, so that any upward force applied to the lower sash is applied directly to the frame of the upper sash and not solely to the screws of the base-plate.
I therefore claim as my invention-" 1. An improvement in sash-locks,which consists in the combination of a locking-plate, and abase-plate to which it is hinged, the said base-plate and the joint of the said hinge being set in a recess in the face of an upright of the upper sash, and said locking-plate being movable on its hinge over the meeting-rail of the lower sash, substantially as and for the purposes described.
2. Animprovement in sash-locks, which consists ofa locking-plate hinged to a base-plate,
the said base-plate being set in a recess in the [3 'face of an upright of the upper sash and hav- WILLIAM GHISHOLM.
