Specification of Letters Patent.
Patented Apr. 29, 1913.
Application filed March 6, 1913. Serial No. 752,270.
To all whom it may concern:
Be it known that I, THOMAS L. MORTI- MER, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window-Sash Locks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to window sash locks, and the object thereof is to provide an improved device of this class which is simple in construction and comparatively inexpensive, and which may be easily applied and by means of which the sashes may be locked in a closed position or in any desired position of adjustment for ventilation or other purposes.
The inventionis fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is an inside view of one side of a window frame and showing the bottom part of the top sash and the top part of the bottom sash in transverse section and showing my improved sash lock in position for use; Fig. 2 a section on the line 2-2 of Fig. 1; and Fig. 3 a section on the line 33 of Fig. 1.
In the accompanying drawing I have shown at a one side of a window frame, at b the bottom rail of the top sash and at c the top rail of the bottom sash, and my improved sash lock d is, in practice, as shown in the drawing, placed between one side 5 of the top sash and the front bead strip 6 which holds the bottom sash in position.
My improved sash lock comprises a pair of lazy-tongs composed of top members (Z and bottom members 0F, and the opposite end portions of which are pivoted together at d, and the separate parts of said members are pivoted together at of". The sash lock is provided at its opposite sides with shoes f and f adapted to bear respectively on the side 6 of the top sash and on the bead strip e, and these shoes are held in place by the pivot pins at d as clearly shown in Figs. 1 and 8. I also provide a vertically arranged plate 9 having a longitudinal slot 9 and provided, in the form of construction shown, with a foot piece 9 adapted to rest on the top bar 0 of the bottom sash and the bottom pivot pin d of the lazy-tongs is passed through the bottom part of the plate 9, and the top pivot pin d is passed through the slot 9 as clearly shown in Figs. 1 and 2, and provided with a thumb nut b.
In the use of this device it is preferably secured to the top bar 0 of the bottom sash at one side thereof and between the side 6 of the top sash and the front bead strip e as shown, and this connection may be made by a screw '5 passed through the foot piece 9 if desired, or in any other way, and whenever it is desired to lock the sashes the thumb nut h is loosened and the top pivot pin (Z forced downwardly in the slot 9 so as to press the shoes f and f firmly into operative position, after which the thumb nut 2 is tightened. This will result in locking the sashes in position and if desired the shoes f and f may be provided with serrated bearing surfaces to facilitate this operation. It will also be understood that the sashes may be opened, or the top sash lowered and the bottom sash raised for ventilation purposes, and the sash lock operated, as above described, for securing the sashes against'movement. It will also be understood that one of my improved sash locks may be used at each side of the window, if desired, and changes in and modications of the construction herein described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A window sash lock, comprising a slotted plate and apair of lazy-tongs comprising top and bottom members, said lazvtongs being provided at their opposite sides with bearing shoes and the bottom portion thereof being pivoted to said plate and the top portion thereof being provided with a pivot pin which is passed through the slot in said plate and provided with a clamp nut.
2. A window sash lock involving a pair of lazy-tongs composed of top and bottom members, said sash lock being adapted to as my invention I have signed my name in be placed in a side of the Window frame and presence of the subscribing Witnesses this to bear on the bottom sash, a side of the top 4th day of March 1913.
sash and the front bead strip, and means THOMAS L. MORTIMER. 5 for opening and closing said lazy-tongs and Witnesses:
locking them in any desired position. G. MULREANY, In testimony that I claim the foregoing S. ANDREWS.
