SASH-BALANCE.
SPECIFICATION forming part of Letters Patent No. 301,723, dated July 8, 1884.
Application filed March 20, 1884; (No model.)
T 0 all whom it may concern:
Be it known that I, ALBERT KARUTZ, a citi zen of the United States, residing at Brooklyn, in the countyof Kings and State of New York, have invented new and useful Improvements in Window-Sash Operators, of which the following is a specification.
My invention relates to apparatus for operating windowsashes; and it consists in the novel construction and arrangement of parts hereinafter described, whereby I obtain an apive in operation.
In the accompanyingdrawings, Figure 1 is a rear view of my apparatus, showing also a portion of the edges of two sashes. Fig. -2 is a cross-sectionon the line mm, Fig. 1. Fig. 3 is asimilar section on the line 31 3 Fig. 1. Fig. 4 is a detail view.
Similar letters indicate corresponding parts.
The letters A A" designate a portion of each relation to each other in the window-frame B, and each of which is provided with a rack, O or O, on one of the vertical edges. These racks G G extend the entire length of the sashes, and they engage with rotary spurwheels D D, which are arranged in the plane of the sashes on horizontal arbors E E, having their bearings in a frame, F, of the window-casing.
On the wheel-arbors 'E E are arranged helical springs'G G -one in a reverse direction to the other-these springs being attached to the arbors at one end and to a fixed bar, 3?, of the supporting-frame at the other end, and. the direction thereof being such in relation to the sashes A A thatthe raising of the lower sash and the lowering of the upper sash has the effect of winding the springs, respectively, on the arbors, due to the turning of the spurwheels D D by the racks of the sashes; and consequently the springs act on the sashes with atendency to balance them. In'order to adapt the spur-wheels D D to the position of the sashes when closed, the wheel-arbors E E are arranged in diiiercnt planes or positions but it is evident that the sashes may be adapted to the position of the wheels.
To the inner side of the supporting-frame F are pivoted two lever-pawls, I 1, arranged, respectively, below and above the spur-wheels D D, and capable of swinging in a vertical plane, each lever-pawl having its free end constructed with a recess, a, to receive one of the lever-pawl is at a short distance from one end thereof, to provide a tail-piece, c, to each pawl, and the pawls are acted upon, respectively, by
springs J J, which act to throw the recessed ends of the pawls in engagement with the spurwheels. A bent bar, K, extends across the supportingirame, under and over the tailpieces 0 of the pawls I and I, respectively, and is providedwith two inclined planes, K, so that by sliding the bar longitudinally its inclined planes come in contact with the tailpieces 0 simultaneously and swing the. leverpawls on their axes, thereby disengaging their recessed ends from the spur-wheels, whereby the latter are free to rotate. The bent bar K is slid longitudinally by means of a lever, O, pivoted at (Z, and loosely engaging the bar by having a lug, a, resting in a recess, f, in the bar, the lever 0 having a projecting handle or finger-piece, O, by which to swing it on its pivot d to slide the bar. This combination provides novel, simple, and efficient means for balancing the sashes and holding them in any adjusted position,- and, further, by the construction claimed a single operating-lever opcrates both locking-pawls simultaneously, to permit movement of both sashes at the same time, if such be desirable, while the necessary spur-wheels, springs, pawls, and locking devices are combined in a single casing for con venient application to the desired position.
I am aware that a sash-balance has been composed of a case containing a spur-wheel to engage a rack on the sash, the shaft of the wheel being connected with a helical spring, and a spring-impelled pin being arranged to engage any one of an annular row of perforations in the wheels for locking the sash in its adjusted position.
I am also aware that a sash-balance has been composed of a casing containing two spurwheels to engage racks v on two sashes, the shaft of each wheel being connected with a helical spring, and each wheel being locked in position by an independent sliding bar having an attached stud to engage the spurs of the wheel, such bar being throwninto engagement with'the spurs by a spring. Such features, therefore, are not broadly claimed by WVhat I claim as new, and desire to secure by Letters Patent, is
1. The oonibination,with the rotating spurwheel arranged in the plane of the sash on a horizontal arbor, the helical spring on the arbor, and the sash having the rack, of the lever-pawl pivoted between its ends to form the tail-piece c, and having its other end constructed to engage the teeth of the spur-wheel,
and the longitudinally-sliding bar K, having an inclined plane, K, for acting on the tailpiece of the lever-pawl, to swing the latter on its pivot out of engagement with the spurwheel, substantially as described.
2. The combination, with the two rotating spur-wheels arranged 011 horizontal arbors, the helical springs on. the arbors in reverse directions, and the sashes having racks, of the two leverpawls, pivoted intermediate their ends to form the tail-pieces 0 c, and the longitudinally-sliding bar K, having the inclined planes K K, for acting on the tail-pieces of the lever-pawls to swing them on their pivots from engagement with the spur-wheels, substantially as described.
Intestimony whereof Ihave hereunto set my 0 hand and seal in the presence of two subscribing witnesses.
