E. W'. HABERMAAS. S-ASH LOCK.
Ndl 604,982. Patented May 31,1898.
- UNITED STATES `PATE-iwi OFFICE.
EDWARD HABERMAAS, OF ST. LOUIS, MISSOURI.
SASH-LOCK.
SPECIFICATION forming part of Letters Patent No. 604,982, dated May 31, 1898.
Application filed March 9 18 9 7.
To all whom zit-may concern:
Be it known that I, Ebw'ARD W. HABER- MAAS, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Sash- Locks, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings,forming a part hereof.
My invention has relation to improvements in sash-locks; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.
In the drawings, Figure l Eis a vertical longitudinal section of awindow-frame, showing my invention applied to the lower sash. Fig. 2 is a similar section showing the invention' applied to the upper sash. Fig. 3 is a sectional detail of the rotatable spindle to which the cords controlling the lOCking devices for the'sashes are securedwl Fig. tis a detail of the key used for operating said spindle. Fig. 5 is a` front elevatiog 'of the casing within which the spindle isr mounted, and Figs. 6 and 7 are respectively detached views of thelocking-latches operating in connection with the lower and upper sashes,
The object of my invention is to construct a sash-lock which uponproper manipulation on the part of the operator will permit the lower sash to automatically move upward to any predetermined height or permit the upper sash to drop any desirable distance, the locks being so constructed that when either sash has been moved to the proper position the latch of the lock will intercept any further movement of such sash and permanently hold and lock the same in position against any attempt to shift or move the same by unauthorized persons.
Serial No. 626,641. (No model.)
weight 6 more than balances the weight of the sash, whereby the tendency of such weight is to always pull the sash up. The upper sash is likewise provided with a cord 4', passing over a pulley 5 and having a weight 6 at its free end, the sash in this case more than balancing the weight 6', whereby the tendency is always for the upper sash to drop and draw the weight after it. Mounted between the frontand rear walls of the casing 7, near the lower end of the frame, is a rotatable or oscillating spindle 8. The periphery of the spindle is provided with two eyes 9 9', located diagonally opposite one another, the eye 9 having secured thereto one end of a cord or wire 10, whose opposite end is connected to the short arm of a pivotedbell-crank or tripping leverll, mounted in a lateral chamber 12, communicating with the casing 7 and located in the line o f the upper rail of the lower sash when'closed, the long arm of the said bell-crank being normally verticah The free end of the long arm of the tripping lever is scarfed and provided with' a pin 13, to which is pivotally secured a latch 11, the pivotal or basal portion of the latch being similarly scarfed, so that the latch and long arm of the tripping lever shall be of the same thickness at their pivotal connection as at'any other portion of their length.l The free end ofthe latch 14 is -provided with a downwardly-inclined locking end 15, adapted to engage the bases of the upwardly-tending series of triangular teeth 16, carried by the side vertical member of the sash. The latch is kept normally in engagement with the teeth by the resilient action of a flexed spring 17, mounted in the chamber 12 and having one end secured to the inner surface of the outer wall of said chamber, the free end of said spring bearing normally against a finger 18, depending from the pivotalpoint of the tripping lever. The spindle 8 is provided with a collar 18, bearing normally against the base of the reduced tubular inner extension 19 of a sectional casin g 20, set into and secured to the window-frame by means oi' screws 21, the said tubular extension serving as a direct bearing or support for the spindle and embracing the latter between the collar 18 and the outer terminal flange 22 of the spindle. The forward portion of the spindle, or that directly supported by the tu- IOO bular portion lf), is provided with a socket 23 for the reception of the shank or stem 24 of a key, the processes 25 of which are adapted to enter the depressions 2G, radiating from the outer end ofthe socket 23 along the fiange. It is apparent that upon inserting the key into the socket of the spindle until the processes thereof are received by the depressions 2G and then turning the key so as to rotate or oscillate the spindle-for example, in the direction as shown by dotted lines in Fig. l so as to draw upon the cord l0, the bell-crank lever will be tripped, so as to draw the locking end l5 of the latch It out of engagement with the teeth 16, and the weight G will automatically pull the lower sash up to any predetermined height, when the operator upon releasing the spindle will cause the spring I7 to restore the latch to its normal position, the latter engaging the teeth 16 of the sash and preventing the same from being raised farther by the weight G. The lower sash can of course be drawn down at any time, the upwardly-in cli ned faces ofthe teeth 1G readily riding over the bevel locking end l5 of the latch. The other eye 9 carried by the spindle has secured thereto one end of a similar cord l0, whose opposite end is secured to the bell-crank or tripping lever ll, pivoted in the lateral chamber 2, also communicating with the casing 7, and located in the line of the lower rail of the upper sash when closed.
From the arrangement of the eyes 9 9 it is apparent that when the key is turned to rock the spindle in a direction to pull on one cord the other cord will remain slack, and vice versa, so that either one lever ll or the other ll can be tripped according to the pleasure of the operator, and one or the other sash is thus controlled. The upper sash 3 of course works similarly to the lower one, but reversely thereto-that is to say, it is provided with teeth 1G tending downwardly, the locking-latch It therefor having a locking bevel end l5,inclined upwardly, so that when the latch is disengaged from the teeth bythe tripping of the lever ll' the said sash, being heavier than the weight 6,will drop until interccpted by a release of the locking-latch. The
upper sash can of course be readily elosed,as 5o the teeth IG freely ride over the upwardly-inclined locking end l5 of the latch Lt. In each case the teeth l0 1G' form a part of a suitable plate carried by the vertical lateral member of the sash.
It is apparent that minor changes might be made in the construction without departing from the spirit of my invention.
Having described my invention, what I claim isl. In a sash-lock, a lower sash a weight in connection with the same, and heavier than said sash, an upper sash a weight in connection with same and lighter than said sash, a series of teeth carried by each of said sashes a bell-crank tripping lever for each of said sashes and located in proximity to the latter, a latch pivoted to one arm of each ofthe trippinglevers and having respectively upwardly and downwardly inclined locking ends coperating with said teeth springs cooperating with the bell-erank levers, a rocking or rotatable spindle, means for rotating the spindle, and cords connecting the periphery of the spindle with the bell-crank tripping levers, whereby the rocking of the spindle in either direction will release either one of the latches from its locked position allowing the upper sash to fall automatically, or the lower sash to automatically move upward.
2. In a sash-lock, a suitable spindle, a socket for the same, radiating depressions at the outer end of the socket, a collar carried by the periphery of the spindle, a terminal flange surrounding the outer end of the socket, a casing carried by the frame and having a tubular reduced extension embracing the spindle between the collar and the terminal flange, said socket and depressions being adapted to receive the shank and processes of a key, respectively, for rotating the spindle, substantially a-s set forth.
In testimony whereof I affix my signature in presence of two witnesses.
