Application fi1ed 0ctober 22, 1910. Serial No. 588,569.
Patented Jan. 16,1912.
To all whom it may concern:
Be it known that I, JonANNns E. VON
vide a simple, strong andeflicient structure of operating mechanism for use in conjunction with the louver sashes to lessen the strain upon the pivotal supports of the I sashes when openmg and'closing the same,
and to provide-an operating mechanismof relatively few parts which are so peculiarly assembled with the sashes that the force exerted through the mechanism is applied at right angles to the sashs, whereby prae tically the full force of the mechanism. is utilized in turning the sashes only, and not" in overcoming friction of the movable parts, such friction occurring in present structures of this nature where the force is applied at oblique angles-to the sashes.
With these and other objects in View the invention consists in the novel combination and arrangement of parts hereinafter described and pointed out in the appended claim, and illustrated in the accompanying drawings, in Which,--
Figure 1 is a vertical sectional view of the preferred form of the invention, the louver boards or sashes being open; Fig. 2 is a similar view of a modified construction; and Fig. 3 is a like sectional view of the construction illustrated in Fig. 2, with the louver boards or sashes closed.
In the drawings, 1 indicates a portion of the ventilating structure on the roof of a building, in the ,sides of which structure are window frames 2, oneonly being shown. Pivotally mounted on studs 3 projecting from the sides of-the window frame 2 are a plurality of narrow. window sashes, window louvers or louver boards 4, the bottom of each sash or louver board overlapping on the outside the top of the next sash or louver board below when in closed position to prevent the'entrance of rain or snow, and also to close the opening in the window frame to the passage of air. The axes of the studs or pivot pins 3 lie in a vertical plane with the result that the sashes or louver boards centrally pivoted thereon will, when closed,-
have aslight inclination inwardly. The sashes when opened swing inwardly at the top, and when closedthey are prevented from forcibly striking each other by means of angularly disposedstop strips 5 projecting slightly fromthe sides of the window frame on opposite sides of the studs, and against which the upper outer and lower inner sides of the sashes bear.
Mounted to turn in bearings 6 which are preferably fastened near the top of the window frame 2 on its inner side, is a horizontal shaft 7 on which one or more sheaves or sprocket wheels 8 will be fastened to carry begrasped and the shaft rotated in either direction. .The shaft 7 also carries a worm 10 engaging a worm wheel 11 mounted to turn in a bearing 12 bolted, to the top of the window frame 2 or the wall-pf the ventilating structure 1. Through the axis of the worm wheel 11 is a threaded opening to re ceive the screw 13 formed on or attached to one end of an operating rod 14-, from'one side of which project a number of spaced pins 15 slidably fitted in slots 16 formed in the free ends of arms 17, each arm being rigidly fastened'on the inner side of asash or louver board near its top. The end of theoperating rod 14 opposite the screw 13 is slidably mounted in a guide 18 Which-latter also limits the extent, of movement of the operating rod by means'of stop plates 19 and 20 fastened thereon on opposite sides of the guide 18 and suitably spaced. When the ro or chain 9 is pulled to revolve'the shaft in the'direction indicated by the arrow, the worm 10 on said shaft will turn the worm wheel 11 in such a direction as will cause the screw 13 and operating rod 14 tovrise until the stop 20 abuts against the under side of the guide 18. The upward travel of the operating rod will, through.
the medium of the pins 15, raise the arms 17 ating mechanism comprises a worm, a worm wheel and a screw, the louversashes may be opened to any position within the limit of the stops 19 and 20 and be securely held in such position.
A simpler mechanism for opening and closing the sashes is illustrated in Figs. 2 and 3. In this construction a crank arm 21 is aflixed on the shaft 7 and pivotally con- I I neeted to a bracket arm 22 projecting at an extending angle from the vertical operating rod 14 on which are ivoted the ends of the arms 17 om the louvers 4. The lower end 14: ofthe operating rod 14 is bent toward the window frame a suitable distance to strike the sill or bottom 23of said window framewhen the sashes are opened and thus limit the extent of their opening.
Fixedonthe shaft 7 and preferably formed integral with the crank-arm 21 is a cam 111g 24 for locking the sashes in closed position.
In this form ofthe mechanism when the rope or chain is pulled to ock the shaft 7 and raise the crank arm 21 into the position represented in Fig. 3, the bracket arm 22. and its attached operating rod- 14: will be carried to the position shown in' said figure, thus closing the pivoted sashes. This movement of the crank arm, it will be observed, both elevates the top .of the 'rod 14 above .1 the plane of the shaft, and brings it near the window frame into position to'be engaged by the cam 24 which, by preventing the rod moving laterally holds the sashes in closed osition. As soon as the shaft *7 is rocked. y the rope or chain in the opposite direction, the cam lug will be withdrawn and the operating rod lowered until its end '14"- strikes-on the-window sill. The downward movement of the operating rod will, of
course, open the sashes.
J It is sometimes desirable'or necessary to remove the louver sashes-from the window frame for repairing and other purposes, and to do this the pivotal connection between the sash and its frame i'smade a separable 5 one. The pivot pins 3, as hereinbefore described, project a short distance from the window frame into the opening filled by the sashes. In the outer ed e of each stile ofeach sash is made an .L-s' aped recess 25 extending from the inner faceof each stile/- toward-the centers thereof, and then upwardly for a short distance, terminating in the present instance midway between the top and bottom of the sash to form seats for the pivot pins. To remove the sash the arm 17 -is detached either from said sash or the operating rod and the sash then turned,
when closed, straight arms rigidly carried upon the upper'rails of the sashes, the" arms having longitudinal slots in their free ends, registering brackets extending inwardly the brackets having *an angular opening,
-- and the opposite bracket having a circular opening therethrough, a rod mounted in the being formed angular in cross section atone end for slidable engagement 1n the angular is held from turning, the rod" further having a threaded rounded oppositeend engaging through the circular opening of theopposite bracket, fixed pins projecting laterally from of the arms, an operating gear threaded on the "rounded'end of the rod and bemg supported from longitudinal movement in the :bra cket' 'havingfthe -circularopemng, and
whereby the rod is moved, longitudinally of the-frame to swing the arms and operate the sashes. j I
