IMPROVED SASH-BALANCE.
The Schedule referred to in these Letters Patent and making part of the lame.
To all Whom it may concern:
Be it known that I, WILLIAM H. PILGRIM, of the city and county of Allegheny, and State o f Pennsylvania, have. invented a new and useful Improvement in Suspending Window-Sash; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consists in suspending the sash of windows, through the media ot' cords, pulleys, and cams inserted in the frame, all constructed, arranged, and operating so that the cords are hidden in the frame, substantially as hereinaiterdescribed.
To enable others skilledin the art to make and use my invention, I will proceed to describe its construction and operation.
In the accompanying drawings, which form part of 'my specication- Figure 1 isa front elevation of a window-frame andl its sash provided with my improvement for suspending the sash.
Figure 2 is a transverse section of the same, when cut through at line g/ of Iig. 1.
Figure 3 is a front elevation of the window-frarne and its sash, vrepresenting the upper part of thesash lowered, and the lower part ot' the sash raised.V
Figure 4 is avert-ical section of the cam and its frame, used for holding the sash-cord in the desired `positionfor holdingthe sash, when either part is raised or lowered.
In the accompanying drawings- A represents the window-frame.
B represents the upper part, and C, the lower part of the window-sash,
The frame and its sash are constructed in the ordinary manner.v g
In the upper part ofthe frame A, and on a line with the outer edges of the sash, arc pivoted grooved pulleys e, and in the lower part, C, of the sash are fittedy frames f, in which are pivoted cams g, as shown in iig. 4.
The frames f are tted in openings, which run in an oblique line from the edge to the front or face cf the sash, as shown in figs. l and 2.
The cords D are secured to the upper part B ofthe sash, and pass up andl overfthe pulleys e, and down and through the cam-frames f, as shown in lig. 4.
On the outer end of the cords D are loops :zg-which are looped over knobs t, secured on the face of sash C.
As the construction and arrangement of the severalparts, and the relation they bear to each other, will he readily understood from the'foregoing description, and by reference to the accompanying drawings, I will therefore proceed to describe the operation of my improvement, which is as follows: Y
By drawing on` the outer ends of the cords D, the part C of the sash will be raised, and the cam g will hold the cords when the sash is raised to the desired height. By raising the lower sash C without drawing on the cords D, the upper sash B will be lowered equal to the rise of sash C.
I wish it clearly understood that I am aware that window-sashes have been suspended by 1n eans of cords, pulleys, and cams,therefore I do not claim, broadly, their use flor suspending sashes. The novelty of my improvement consists is so arranging the cords, pulleys,
and cams as that they are hidden in the frame of the window and its sash.
Having thus described thev nature, construction, and operation of my improvement,-
VVl-lat I claim as of my invention, issuspending window-sash, through the media of cords Dpulleys e, and cams g, inserted in the frame, all
constructed, arranged, and operating so that the cords are hidden in the frame, substantially as herein described, and for the purpose set forth.
