UNITED STATES PATENT OFFICE.
I ALFRED SETTEBSTROI-AND GUNNAB. ERICKSON, F PORT RICHMOND, NEW YORK.
A means all of a conventional type.
l WINDOW SAFETY LOCK.
To all whom z't ma/y cof/wem:
Be it known that we, ALFRED SETTER- sTRoM and GUNNAR' ERICKSON, citizens of' Sweden, residing at Port Richmond, in the county of Richmond and State. of New York, have invented certain new and useful Improvements in lVindow Safety Locks, of
which the following is a specification.
VOur said invention relates to a windowr safety lock and it is .an object of thesame to provide a lock for a window sash which can readily be put intol and out of locking position, which when 'in locking positionl will lock the window securely and which cannot readily ybe, tampered with to put it out of action. l
Referring to the accompanying drawings, which are made a part hereof and on which similar reference charactersindicate similar parts,
Figure -1 tion Figure 2 a similar view taken at an angle to that of Figure 1 and showing the locking device in a different position, and
Figure 3 a horizontal section of the( device.
In the drawings reference character 10 .indicates the lower sash of a window having an upper sash 11 and ides and operating The device of our invention comprises. an upright bar 12 which is preferably square in section and is bent at the upper end and flattened to form a. securing bracket 13 attached to the upper sash by' the screws 14. At its lower 'end the bar is rounded as shown at 15. and beneath this rounded part the bar carries a twisted flat bracket member 16, one part of which is located at right angles to the bar and1 is secured as by a screw 17 to the lower member of the uppersash. The other part lies in a plane parallel to the bar and is secured as by screw 18 to a side member of the sash. A latch 19 is slidably mounted on the bar 12 and is normally held away from the rounded part of the bar by a short coiled sprin 20. The latch has a button 21 at the top or convenience in forcing it down against the tension of the spring and in. its lowermost position it may be rotated into either of the positions shown in the figures. In the position of Figure 1 the lower sash can he moved up 'and down freel in the dotted line positlon of Figure 3 (a so shown in full lines in Figure 2) the latch extends is a perspective of my invenover the upper member of the lowersash. Should the sash now be raised it will strike thelatci and move it into the dotted line positionl of Fi re 2. The bar and the latch" are" both ardened so that the latch will not slide on the bar (or at any rate only to a slight extent) but will bind and f thus prevent further raising of the sash. If lthe vsash is loweredl the latch will fallk to its lowermost position and will thus effectively'prevent raising of the sash. When in lookin position the latch of course also prevents owering of the upper sash.
It will be evident to those skilled in the art that numerous modifications -can be y made in our device without departing from the spirit of the invention and therefore we do not limit ourselves to the specific embodiment of the invention shown in the draw-4 in and described in the specification but on y as indicated vinthe appended claims.
Having thus fully described our .said in'- vention, what we claim as new and desire to secure by Letters Patent, is:`
l1. Ir a window latch, a bannen-circular..
in cross section, means for attaching the same to a window sash, a latch slidably mounted on and having an opening snugly receiving said bar, a rounded formation' at thelower end of the bar whereby the latch may be pivotally Imoved about the bar, and a coiled spring surrounding` said rounded portion to hold the latch normally on the squared portion, substantially as set forth.
2. In a latch for windows having upper and lower movable sashes a bar secured to the upper sash and extending vertically for a length correspondin to the desired* latch: ing range of the winv ows, and a latch carried by the bar and adjustable. lo'n itudinally thereof throughout its length w ereby relative movement of the sashes may be prevented within the limits of the said latching range said latch being movable into and out of position to contact the lower sash when in a predetermined position on the bar, substantially as Set forth. Y
3. A latch for windows having movable sashes, comprising a bar to be secured to one of the sashes and extending in the direction of the longitudinal movement 'of the sashes for a length corresponding to the desired latchin range of the windows, and a latch adjusta le longitudinally of said bar fon limiting the relative "movement of the sashes at any point within the limits of the' latching range, said latch being movable into and out of position to contact :L sash when in a predetermined position, substantially as set forth.
4. In a, latch for windows having upper and lower movable sashes, a bar secured to the upper sash and extending vertically for a length corresponding to thc desired latching range of the windows, alatch slidably and non-rotatably mounted on said bar and pivotably movable when in a. predetermined position on the bar at substantially right angles into and out of the path of movement of the lower sash, said latch member being manually sldable alon said bar to permit various adjustments o the sashes but resisting sliding movement when engaged by the lower sash, Substantially as set forth.
In witness whereof, we have hereunto set l our hands and seals at Port Richmond, New
York, this twenty seventh day of January,
A. D. nineteen hundred and twenty-three. ALFRED SETT'ERSTROM. [Ls] GUNN AR ERICKSON. [L. 5.]
