' WIT/lesse.; C/w/ UNITED STATES PATENT OFFICE.
THOMAS J.Y SUTTON, OE NEw YORK, N. Y.
SASH-LOCK.
SPECIFICATION forming' part of Letters Patent No. 568,992, dated October 6, 1896.
Application filed January 22, 1896. Serial No. 576,374. (No model.)
To @ZZ whom it may concern,.-
Be it known that I, THOMAS J. SUTTON, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sash-Locks for Windows, of which the following is a speciication, reference being had to the accompan ying drawings, forming a part thereof, in which similarletters of reference indicate corresponding parts.
This invention relates to sash-locks for windows; and the object thereof is to provide an improved sash-lock which is sim ple in construction and operation and comparatively inexpensive; a further object being to provide a sash-lock which will admit of the sashes being adjusted within certain limits, so as to provide means for ventilation; and with these and other objects in view the invention consists of the construction, combination, and arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the'accompanying drawings form a part, in which` Figure l is a front view of a portion of a window-frame, showing also a portion of the upper sash mounted therein and myimproved lock in position; Fig. 2, a transverse section on the line 2 2 of Fig. l; and Fig. 3, a vertical section of the adjacent sides of the upper and the lower window-sashes, showing a modified form of lock connected therewith, said lock being also shown in section.
In the drawings forming part of this specification, A represents a portion of a windowframe, and B and C a portion of the upper and the lower sashes mounted therein, and in Fig. l the lower sash is raised slightly, so as to show the operation of my improved lock when it is desired to raise the lower sash or lower the upper one for the purpose of ventilation.
In the practice of my invention I secure to one side of the upper sash a plate D, which is provided with a vertical slot d, at the lower end of which is formed a transverse slot d2, which is shown in dotted lines in Fig. l, and I also provide a plate G, which is secured to the lower sash and transversely thereof and on which is mounted a sliding plate or bar H,
which is provided'near its inner end with a longitudinal slot 71., which is adapted to receive a pin g, which is secured to the plate G.
The inner end of the sliding plate or bar H is provided with a transverse head h2, which is formed by notches Or recesses h3, cut in the sides thereof, and hinged to said sliding plate or bar adjacent to the outer end of the longitudinal slot 7i is a hingedplate K, which is provided at its outer end with an upwardlydirected extension 7c, and the outer end of the plate K is passed beneath a band L, which is secured to the plate Gr, and said plate K is also provided with a shoulder or projection k2, which is adapted to abut against said band L, as shown in Fig. 3, and formed in the upper surface of the plate H is a cavity or recess in which is placed a spring M, which Operates to force the hinged or locking plate upwardly and in contact with the band L, as is also shown in said figure.
The only difference between the construction shown in Figs. 1 and 2 and that shown in Fig. 3 consists in the construction of the plate D, and in Fig. 3 this plate is much shorter than in Figs. l and 2, and the longitudinal slot d therein is omitted, and the locking-plate I-I in the operation hereinbefore described is simply forced into a hole or opening formed in the lower end thereof.
The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.
It will be understood that both forms of construction shown and described may be employed in connection with Said sashes, and in this event one of said forms will be placed upon one side of the sash and the other upon the other side, and if this is done the construction shown in Fig. 3 will serve as an absolute lock and prevent the movement of the sashes when in Operation, while those shown in Figs. l and 2 may be employed for locking the sashes together and preventing the movement thereof within certain limits, thus providing for the ventilation of a compartment, as will be readily understood.
In order to operate the construction shown in Figs. l and 2, the upper sash is raised to the highest point and the lower one lowered to the lowest point, and the sliding plate H IOO is then shoved forward, so that the head 7L? thereof will enter the transverse slot d2 at the bottom of the ordinary slot d, and in this position of the part-s the hinged plate K will be forced upwardly by the spring M, and the shoulder 7a2 thereon will abut against the band L, and the plate II cannot withdraw from its connection with the plate D without depressing said hinged plate K, and in this position of the sliding or locking plate II the lower sash may be raised to a slight extent or the upper one lowered.
If both forms of locks are employed, as hereinbefore described, it will be understood that the lockshown in Fig. 3 is not in operation and cannot be operated except when the sashes are closed, and at this time the form of construction shown in Figs. 1 and 2 will not be necessary, and instead of applying both forms of my improved lock either one thereof may be employed separately, if desired.
Having fully described my invention, I claim as new and desire to secure by Letters 3 Patent* plate fixed on the upper sash and provided with a vertical slot opening into a transverse slot at the lower end of a plate fixed on the lower sash at right angles to the first-mentioned plate, a longitudinally-slotted sliding plate or bar, provided with a transverse head, mounted on said lower sash-plate, a pin in said plate adapted to engage in the slot of i said bar, a plate hinged to said bar adjacent to the outer end of the slot thereof, said hinged plate being provided with an upward projection, a band secured to the lower sashplate, a shoulder on the hinged plate adapted to abut against the said band, a spring fitted in a recess in the sliding bar designed to operate to force said hinged plate in contact with said band, all constructed and arranged
