DEVICE FOR BALANCING SASHES. APPLICATION FILED JULY 24.1906
ALFRED MOLE, or FORDSBURG, TRANSVAAL.
DEVICE FOR BALANCING SASHES.
Specification of Letters Patent.
Patented Feb. 11, 1908.
Application filed July 24' 1906- Serial No. 327.474.
To all whom it may concern:
Be it known that I, ALFRED MOLE, a subject of the King of Great Britain, and resident of Fordsburg, Transvaal, have invented certain new'and useful Improvements in Devices for Balancing Sashes, of which the following is a specification.
This invention relates to the hanging of window sashes and more particularly to.
sashes hung so that they balance each other. The primary object of the. present invention'is to provide for the hanging of the sashes without the employment of weights,
weight boxes and the usual fittings while at the same time permitting the top sash to be opened without openin the bottom sash and. so that the top sash Wlll travel at twice the speed of the bottom sash.
According to the present invention the sashes are connected with each other at each side by means of a rope chain or cord. One end of each of the cords is fixed in a conven .ient manner to the pulley stile at or aboutthe level of the top rail of the bottom sash. The cord, rope or chain, from its point of attachment to the pulley stile passes down a recess or groove therein, under a pulley which is fixed to the side rail of the bottom sash and is movable with it, then up and round a pulley arranged above the'heador in the top of the window frame, then in a downward di rection and down a groove in the side rail of the to sash to which it is preferably adjustably xed.
The invention will now be described in detail by aid of the accompanying drawings, wherein Fi ure 1 represents an elevation of a window rame, from the inside, showing the top side rails.
and bottom sashes open, and Fig. 2 is a section of Fig. 1' on line a:-z.
A re resents the top sashcomprising the top ra' a, the bottom rail a and t e two side rails a. a. B is the bottom sash of which];
is the top rail, 6 the bottom rail and b b the The bottom rail 0 of the top sash and the top rail 1) of the bottom sash constitute the meeting rails when the window'is closed; In the drawing the bottom sash B is shown twice the height or length of the top sash Aso that the eight. of the bottom sash is a proximate y twice that of the to sash. Tl ie window frame comprises the sill the outside and inside liningsc c, the pulley stiles c c,
the rope to the pulley stile c a frame is fixed a bracket or casing D in which is revolubly mounted a grooved pulley d. These pulleys d are set so that their axes are over the center of the the diameter of the pu leys is equal or approximately e ual to the distance between the centers of t ie sashes A B. In the case of thick sashes instead of increasing the diameter of the pulley d, two pulleys at each side of the frame might be employed. These pulleys d are preferably first fixed to a piece of wood E which may be fixed tothe head 0' by screws screwed in from the underside. To provide for access to the pulleys d a pocket may be provided at the center of the head so that by unscrewing the screws either pulley d may be removed and replaced. The pocket may be provided either in the process of manufacture or may be cut therein after the window has been fixed, should it be necessary at any time to obtain access to the pulleys.
Two chains, ropes or cords e are employed, one for each side of the window. I refer to employ wire ropes e of a suitable't iickness as they are not so liable to stretch after being fixed and adjusted. One end of each of the ropes e is fixed to the pulley stile c c at or about the level of the top rail 6 of the bottom sash when the latter is in its closed position. This end of the wire 6 may be fixed either by nails or screws, or, but preferably, by turning it round a small pin and splicing it into itself.
e represents the fixing attaching the end of The pulley stile is constructed with a vertical'groove or recess (3 down which the IQ ee asses from its point of attachment to t e st1 e. To the side rail 6 b of the bottom sash is fixed a arting beads c and pulle F which runs in grooves f formed in the slde rail of the bottom sash-B and the recess or groove e in the pulley stile. The rope e asses under this pulley F, then up a vertica groove f formed in the side rail of the bottom sash B on the inside and over the pulley'dfixed to the head a The cord c then passes in a downward direction downa groove I f in the inner edge of the side rail of the top sash A, being attached at its lower extremity to a loo or U shaped piece of wire H fixed to a nut located in a recess f 2 in the side rail of the top sash A. A holef is formed in the the recess f bottom sash B being twice the Weight of the bottom rail a of the top sash In the hole f 3 and projecting up'into the recess f 2 and engaging the nut h is a screw or bolt h the head k of which is located in a recess f in the bottom edge of the bottom rail a. The arrange'ment'is' the same at each side of the window.
The construction and operation of the means for adjusting the ropes are the same as those described in my prior application previously referred to. By turning the screw or bolt k in one direction the cord 4; may be lengthened and by screwing it in the reverse direction the nut h and loop H are drawn down, drawing down the rope c to take up any slack.
It will be understood that the weight of the top sash A, and half the weight of the bottom sash-being carried by the ends of the'cords e fixed to the pulley stile 0 0 the other half which is carried by the endsof the cords e fixed to the top sash A, serves to balance the latter. Instead of making the bottom sash twice the size of the top sash, it will be evident that the same result may beattained should the sashes be made of the same dimensions, to make the bottom sash twice or a proximately twice the weight of the top sash y constructing it of heavier wood and glazing it with heavier glass.
To enable the top sash A to be opened without opening the bottom sash B or without leaving any through passage under the lower v edge of the bottom sash; the window frame should be constructed with a deep sill as indicated at C. If this sill C be made say three inches deep then the bottom sash B may be raised three inches without opening it to' the outside, while the top sash A will be lowered 'six inches or thereabouts. Assuming the passing up into I bottom sash B to have been raised so that an opening of say four inches is left between the bottom rail b and the to of the sill G, then the bottom sash B will have been raised a total distance of seven inches and the opening between the top rail a of the top sash A and the head 0 of the Window frame will be fourteen inches or thereabout.
A small pocket indicated at J is out in the ulley stile c c at one side of theiwindow rame up to the groove or recess 6 in which one half of the pulley F runs, to permit the pulley to pass in and out of said groove or recess in the operation of removing the sash B from the window frame.
in the inside lining 0 so as to allow of access to the pocket J in the pulley stile without disturbing the lining after the window has been fixed. The inside lining may have two sawcuts made in it to locate the position of the pocket J. in the pulley stile so that the piece could be cut out'should it at any time be required to remove the sash.
What I claim as my invention and desire to protect by Letters Patent is p A corresponding pocket indicated at J may also be provided In combination, upper-and lower sashes,
pulleys fixed to the ower sashes, pulheys fixed to the window frame, cords each fixed at one end to the window frame, passing around said pulleys, and each fixed to the upper sash, and means carried by the upper sash for adjusting each of said cords.
In witness whereof I have hereunto set my 'hand in the presence of two subscribing witnesses.
ALFRED MOLE. Witnesses:
