PATENT OFFICE.
ADOLPHUS JAMES PARK, or AUCKLAND, NEW ZEALAND! SPECIFICATION forming part of Letters Patent No. 791,645, dated June 6, 1905.
Application filed $eptember 10, 1904:. erial No- 223,980.
To all whom it may concern.-
Be it known that I, ADoLPHUs JAMES PARK, a subject of the King of Great Britain, residing at Auckland, New Zealand, have invented certain new and useful Improvements in Means for Suspending and Operating Window-Sashes, of which the following is a specification,
This invention relates to improvements in the means whereby window-sashes may be suspended in their frames without the use of the ordinary sash-cords and weights and may be easily operated to open or closethe sashes; and it consists in novel clamping devices for the cord.
The invention is illustrated in the accom-- same. Fig. 3 is a detail view of one of the pulleys B. Fig. 4 is a detail view of the ower stop,
In carrying out the invention a pair of inverted pulleys are mounted in the top of the window-frame A, one near each side thereof. A pulley a is also loosely mounted on the inside face of the top bar a of the top sash A, at each end thereof. A flexible wire cord B of any a proved strength is passed across the top of the top sash A, each of its two ends being then passed upward around the pulley B at the respective side of the sash and then downward around the pulley secured within the window-frame on that side. The end or ends of the cord B are continued downward and pass through clip B or clips secured one on each side of the top of the bottom sash A The clipper B or clips are so constructed as to allow of the cord B passing freely through them when the end or ends are given a downward pull, but which will bind upon the cord B and hold it when the upward pull caused by the weight of the top sash A is exerted upon it.
A suitable form of clip consists of a metal plate 0, adapted to be secured upon the face of the lower sash A and to which a lever-arm D is pivoted at one" of its ends, while its other 5c end isvfree and is formed with an opening at in it, through which the cord B may be passed. A stop a is located below the arm or lever D, against which the arm will tend to drop and rest by gravity in a horizontal position,
at which time the wall of the passage (1 is vertical, allowing the cord B to be drawn freely through the same. When, however, the cord is released and allowed to move upwardly, the friction of the cord in the opening will raise the lever against the action of gravity. Above the lever is located a stop or member I), so that as the lever swings upwardly the cord is bent or kinked, and thereby held against movement by frictional contact between said parts. The top sash A will thus be held by the weight of the lower sash A and the lower sash A may be raised and closed and the upper sash 'A lowered and raised simultaneously by operating the end or ends of the cord B. The clips will hold the cord at any points, so that the top sash A may be suspended at any height. The lower sash A may be raised independently of the top one by pulling on the ends of the cord B and lifting the sash A at the same time. When the ull is released, the sash will be'caught and eld at the desired height.
What I claim as my invention, and desire tocsecure by Letters Patent, is
The combination with the window-casing and upper and lower sash of a pair of pulleys secured at the top of the casing and a pair of pulleys carried bythe upper rail of the upper sash, a cord having one end secured to one side of the top rail of the lower sash and passmg thence over said pulleys and having its free end depending in proximity to the other side of the lower sash and clamping means for said free end comprising an arm pivotally connected to the lower sash and having an In witness whereof I have hereunto set opening through which said depending end my hand in presence of two witnesses. passes, said arm being adapted to be held by gravity in a horizontal position and to swing ADOLPHUS JAMES PARK upward against a stop to clamp said depend- Witnesses: ing end automatically when it is released, BRAYBROOKE FEATHERSTONE GRIFFIN,
substantially as described. WILLIAM JAMES DALTON.
