ROOF-LIGHT.
Specification of Letters fatent.
Patented @et. 21, 1913.
Application filed July 13, 1912. Serial No. 709,237.
To all "whom it may concern Be it known that I, ALBIN KLEIN, a subject of the Emperor of Germany, residing at Erfurt, Germany, have invented certain Improvements in Roof-Lights, of which the following is a specification.
The present invention relates to rooflights of the kind composed of a plurality of superposed louvered frames which are adjusted by means of two sets of lazy-tongs levers.
The invention consists in the combination with a roof-light of this kind of interconnected double-armed actuating levers which are pivoted to the base frame and provided with a long and a short arm set at a wide angle to each other, the short arms of the levers being connected by means of links to the center pivot of the lower pair of lazytongs. The arrangement is such that the links occupy an upright position and move longitudinally when the actuating levers are rocked. By means of this arrangement the adjustment of the roof-light becomes a very easy operation.
In the accompanying drawings the invention is illustrated by way of example, Figure 1 representing a sectional View of the roof-light showing one set of lazy-tongs levers, Fig. 2, a section of the roof-light on the line A-B of Fig. 1, Fig. 3, the same view as Fig. 1, showing the frames in closed position, Fig. 4, views on an enlarged scale showing different posit-ions of the linkages employed for connecting the levers to the frames, Fig. 5, similar views showing a modification of such linkages, 6, a sectional view of a roof-light showing a modified arrangement of the actuating levers, Fig. 7, a view of a roof-light opening angularly to the base frame, and Fig. 8, a view showing a still further modification of the arrangement.
The frames 5 and 6 are supported on a base frame 4 by means of two sets of lazytongs levers arranged at two opposite sides thereof. The ends 1, 2 and 3 of the levers are pivoted directly to the frames 4, 5, 6. The opposite ends 7 8, 9 are, so as to allow for the horizontal adjustment of the lever system, connected to the frames by means of intermediate links 10. These links and the arrangement of the same are shown more clearly in Fig. t. One end of the link is pivoted at 12 to the frame and the other end at 11 to one of the levers, the pivot 11 being secured to a laterally projecting lug formed on said lever. If a very wide adjustment should be required, the arrangement shown in Fig. 5 is resorted to, two interconnected links 21 and 22 being here employed for connecting the pivots 11 and 12.
For adjusting the levers and the frames two double-armed bent actuating levers are provided which are pivoted to the frame 1 at 15 and connected to the two sets of levers, one to each. The ends of the long arms of the actuating levers are interconnected by a transverse rod 13 so as to allow of being p irned jointly by means of a chain 16 or the In Figs. 1 to 3 the short arm of the actuating lever is connected to the end 9 of the lower arm of the lazy-tongs. When the window is closed, the elements have the position shown in Fig. 3, and a pull on the chain 16 causes a horizontal displacement of the pivot 9 and a consequent opening out of the frames as shown in Fig. 1. With the lovers arranged in this manner only a very slight exertion is required for opening the window, and the frames are adjusted in a positive and therefore uniform manner. In the case of large frames and long leverarms only a very slight horizontal displacement of the pivots takes place. Such levers are preferably actuated as shown in Figs. 6 and 7, the short arm of the lever 14; being adapted to act in an upward direction, through the medium of links 17 on the pivot 18 which connects the lower lazytongs levers at the point of intersection. Also in this instance an easy adjustment of the frames is insured.
If the roof-light is employed on a very steep roof, it is essential that the frames should open out more at the lower than at the upper edges and moreover move slightly backward so as to prevent the admission of rain. This is effected by making the leverarms of unequal length as shown in Fig. 7, the same system as shown in Fig. 6 being otherwise employed.
By the arrangement shown in Fig. 8 a very extensive movement of the frames can be effected by a comparatively short movement of the actuating lever. For this purpose the short arm of the lever 14 is pivoted to a bar m which is rigidly secured to one of the arms of the lazy-tongs levers just above the pivot 18, the lower arm of the same lever being discarded. The upper frames will thus be supported on the frame l at 1 and 15. By this arrangement the opening of the window will require more force which, however, may be compensated for by increasing the length of the long arm of said lever; Otherwise this construction will be more simple and therefore cheaper.
I claim:
In a roof-light of the character described, the combination with a plurality of superposed louvered frames and two sets of lazytongs levers arranged at opposite sides of said frames for the support and ad ustment of the same, of interconnected double-armed actuating levers pivoted to the base frame and provided with one long and one short arm set at a wide angle relative to each other, and llnks connectmg the short arms links occupy an upright position and move in a longitudinal direction, substantially as set forth.
