SAFETY WINDOW LOCK.
APPLICATION FILED JAN-7.1920.
Patented Sept. 14,1920.
3 mm nt oz sur s M time nanny EOILCEE'I, on NEW YORK, n.
SAFETY wmnow-Locm T 0 all whom it may concern Be it knownthat I, HENRY PoLoEK, a citizen of the United States, andresident of New York city,"in the county of New York and State of New York, have invented certain new and useful Improvements in'Safety lVindow-Loeks, of which the following isa specification; a 1 p i T This invention relates to new and useful improvements inwindow locks and more particularly to a lock which may not be tampered with from the outside of the window.
Another object of my invention resides in providing a device which willpositively look a wlndow.
A. further ob}- ect of my invention is to.pro-
vide a device which may not only be unlocked from thatside of the sash on which I the handle or knob is provided, but which will resist its unlocking operation unless the knob is turned in a desired direction.
With these and other obiects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be more fully apparent in the following description and from the accompanying drawings, forming part of this specification, in which:
Figure l is a sectional view of my device Fig. 8 represents my device in a totally locking position.
Fig. 9 represents my device in disengagedv position. 7 I
Fig; 10 is an elevation showing a window- With my device attached.
Referring to the drawings, 10 designates one window sash through which passes the operative part of my device, 11 is another window sash or cross member in which lodges the inoperative portion of my lock.
' The housing, shown in various views in Figs. 2, 3, 4, and 5, comprises a fastening plate 12 provided with countersunk holes 13 for receiving screws or. other fastening means 14:, by means of which the plate is s m te m n- 1 I Patented Sept. it, rose.

attached' to cross member 10. Extendin outward from plate 12 is a conically shaped neck or extension 15, having an aperture 16. Opposite the neck and adgacent to the attaching facev of platelfZ is a tubular member 17 adapted to pass through sash 1O prefs er'ably at its center, as may be seen'in Fig.
Y 10. The tubularmember possesses'a pair of opposite "disposed" longitudinal slots 18,. terminating at the free end of the cvlinder into peripheral recesses 19, as may be clearly seen in Figs. ,5 and 6.- i
Opposite the open end of thetubular mem: her 1? and attached to the other sash 11 of the window,is a socket comprising a fastening plate 20 provided with countersunk holes 2l'for receiving'screws or other attaching 1 .means' 22. Extending from the plate 20 into and to about half the width of the sash.
is thiinble 23 with a chamferededge 2 l'at its uuided in thecylindrical opening 16 of' the neck piece 15 is a lock-bolt 25'equ1pped' at one end with a substantially conically shaped knob or handle 26, and provided at its other end with a cone-shaped point 27. 'The reduced portion of the knob possesses a avliich hears a coil-spring 30 at one end, the
other end of which rests ina recess 31 provided atthe broader portion of neck 15. I 1 When the windowis 'to be locked, the
meeting sashes l0 and 11. are brought -.in po- I sition shown in;Figs. 9 and 10, while the bolt is turned and pulled out by way'of the ,knob' in such a way as to cause the pin 20 to enter the guide-slots 18.- By pullingthe H i knob, the spring 30 is compressed. lVhen now the sashesarein positionand the thim his opening faces the bolt,rthe knobis re leased, and thebolt is permitted to enter of thesash on which-the knob is provided b will prove useless. f
I am aware of theexistence of a number of patents on similar devices and I herewith disclaim sameflrestrict ng my invention to the general construction and combination of parts as shown in the drawings and described and claimed in this specification.
I reserve however for myself the. right to make improvements or changes Within the scope of my invention to'meet various conditions.
What I claim is:
In a sash fastener, the combination With meeting cross members of'an outer and an inner window frame, a housing comprising a tubular receiver, adapted to pass through one or said cross members, having a pair of opposite disposed longitudinal guide-slots terminating into a pair of peripheral stop-- recesses openat the extreme end of said tubular receiver, a fastening plate forming an integral part of said receiver, a conical neck extending opposite said receiver from said plate; a socket, having a similar fasday of January A. D.
tening plate, adapted to be attached to said other cross member, a lock-bolt having a large hand knob at one end, adapted for turning and pulling said belt, a conically shaped point provided at the other end of the bolt normally extending into said socket, a pin passing through said bolt and extending into said slots, a spring bearing against said pin and a seat provided in said neck, said spring causing said bolt to normally protrude With its pointed end into said socket, said bolt being prevented from leaving said socket when its knob is turned and said pin engages said peripheral recesses of said tubular receiver.
