DEVICE FOR CON Filed Oct. 27,
Patented June 4, 1940 UNITED STATES PATENT OFFICE nEvIcE` Foa ooNrrRoLrlNG VERTIGALLY p, SLIDING WINDOWS William Young, Wishaw, Scotland Application October 27, 1938, fSe'rialNo. 237,352
` i In Great Britain November 2, 1937 s claims. (cl. 26S- 132) m great to operate the handle comfortably without a considerable reduction in gearing.
The object of the invention is to provide simpliiied means which need not be rotated so many times as heretobefore and further to produce a l device which will require a small amount of force or pressure toroperate it.
Another object of the invention is to provide an improved window which cannot be lowered without operating the winding handle, but which can be closed without touching the operating handle. i A still further object of the invention is to provide means which permit non-rectangular windows to be operated without the employment of skew cut pinions and gearing. l i
` tion of the frame removed.
Figure 5 is a detail. Figure 6 is a plan of Figure 5 with the bracket omitted. i
Figure 'l is an alternative formof construction 40 to` Figure 5.
Figure 8 illustrates alternative means for operatively connecting the sliding window to theioperating mechanism. l
In carrying the invention into effect according to the form illustratedin Figures 1, 2, 3 and 4 as applied,.for instance,l` to half-drop `windows'the top or sliding pane I is `provided with` two racks `2,.one at each side,l which are adapted to be enkgaged by pinions 3.
`On one side of the nut lll is provided a number 15` of teeth I`I and on the casing is provided a housing l 2 in which is mounted a pinion l3which engages with the said teeth. A suitable shaft lll with a handle I5 thereon is secured to the pinion i3 so thatrotation of the handle will move the 20 saidnut I ll longitudinally along the casing. Suitable bearings are provided for the pinion spindle and the handle in `the housing l2 which is mounted upon the casing. n. 1 Situated between acollar I (i near one end of .25 thecasingand the nut `Il) islocated a compression springhl'l such `that as the nut is moved towards the end of the casing,` the spring Il is `compressed and will tend to push the nut ll)` in the opposite direction. Thespringis so arranged 30 will rotate `theshait 8 which in turn will rotate the pinions 3 engaging the racks 2` on either side yof the sliding pane of :the window which `will be moved up or down according to the direction of `rotation of thehandlel By balancing the sliding 40 pane with the spring, Veryylittle force is neces- ;sary to rotate the shaft and therefore a few turns `thread on the shaft and the size of the `pinion engaging with the rack.
The pitch ofthe thread onithe shaft 8 is pref- Merably made so that it is non-reversible and is so 450` arrangedthat the window islocked in any posi- `tion and'cannotbe opened orpusheddown without rotating the handle, but, on the other hand :can be pushed `upgand'shut withouttouching the handle; Thislis agreatY advantage'in buses, be- `55 cause should any windows be leftlopen they can be closed from the outside with a broom or the like when washing the bus instead of having to enter the bus and close all the windows by rotating the handles.
In order to give a constant b-alance to the sliding pane of the window for all positions, the thread or the scroll upon the shaft may be. of varying pitch and in this manner canbe made to give al constant pressure to the shaft so as to balance the Weight of the Window in all positions;
If desired, the casing for housing the threaded shaft or scroll may be mounted directly upon the usual guard rail provided upon the upper ledger of the lower or fixed pane ofglass of a halfof the guard rail as hereinbeforedescribed, ac;
cording to circumstances.
Instead of cutting a thread or scroll upon `the shaft by machine means, the shaft may be formed of any suitable section, and then twisted to form a thread or scroll thereon. Similarly, the nut may be provided with an internal twisted section corresponding to the 'shaft by breaching a spiral hole therethrough by means of a drift. When a lvarying pitch is employed the nut may be provided'withV a lball I8, as` shown in Figures 2 or 3, or witha very small portion of its length having either the internal thread thereon or a cross section corresponding to the cross section of the twisted shaft.
Although the form of the device given above ifor operating the windows has beeny described with reference to half-drop windows, it may equally Well be applied to whole-drop or fulldrop windows. Further, as shown in Figure 8, instead of' the sliding pane of the window being actuated by pinionsengaging with racks, drums 2l, located one on each side of the window frame which Wind up tapes, cables or the like 2B may be employed, or lany other means 'may be applied to the ends of the threaded shaft or rod.
According to a further form of the invention mechanism is providedat each end withl a flexible connection 20 as shown in Figures 5I 4and 6,
Which is also preferably made torsionally resilient. These'flexible connections are connect- `ed toy two pinions V3, for example, which are mounted in independent housings I9, shown in section inHFigure 5, provided upon the sides of the frameV or uponthe brackets which may be femployed to support the winding mechanism.
Since the housings vare independent the pinions can be mounted at any angle to suit the angle of the racks o n windows which vare not rectangular, thus saving the cutting of the teeth of the 'racks or the pinions on the skew.
Instead yof `making theexible lconnection of Ya strip 2U, it maybe formed by. a portion of a fpendently of any guard rail which may be provided on the vtop edge ofthe lower fixed pane or fit may be mounted upon `the said guard rail or` 70 uponthe upperedge of the sliding pane, or upon the top of the fixed frame or pane and the sliding pane suspended from the shaft or scroll by n cables, tapes or the like. When the mechanism is mounted'upon the sliding pane, the drums or pinions aresecured rigidly "to the ends of the shaft or scroll 8 and the racks, if such be einployed, are fixed. In the case of full-drop Windows, the mechanism may be mounted at the bottom of the frame'in the usual manner or on the top of the sliding pane or upon the top of the Window frame or pan. In all cases, except where the pinions, drums, or the like are independently mounted inY separate housings, they are rigidly securedto the ends of the shaft or scroll 8.
These flexible and torsionally resilient connections will prevent overwinding and will absorb shocks and Vibrations so that injury to the operating `mechanism vis minimised. Further, should the sliding pane be moved up and distortionhave occurred so that one corner thereof touches the top rubber of the window before the other corner thereof, the flexible and torsionally resilient connections permit the pinions to rotate relatively to one another and thus sufcient pressure can be exerted on the lower edge of the sliding pane to ensure that the upper edge of the said pane engages with the top rubber of the Window frame throughout its length.
