VENTILATOR-SASH MECHANIISM.

To all whom t may concern:

i Be it known that I, FRANK D. MOON, a citizen of the United States, residing at Edgewater, in the county of Bergen and State of New Jersey, have invented a new and useful Ventilator-Sash Mechanism, of which the following is a specification.

My invention relates to improvements in mechanism for opening and closing a con tinuous line or continuous lines of Ventilating or other windows or sashes, and the objects thereof are to provide means by which said lines of windows may be operated from a single shaft, and from a convenient point on the floor of the building; to provide means for operating a part or all of said windows simultaneously, to provide for thev tight closing of said windows and further to provide automatic tensioning means which will insure the operation of the mechanism from the shaft.

Other objects and advantages of my invention will appear from a description of the par ticular embodiments thereof1 illustrated ih the accompanying drawings in which- Figure l is a transverse sectional view of a monitor roof provided with the mechanism; and Fig. 2 is a similar view showing a different form of the invention.

In the drawings, Fig. 1, my device is shown as applied to a so called monitor roof l such as is commonly employed for the ventilation and lighting of a factory building and which extends along the main roof 2 of the building. Upon the central truss members 3 of the monitor` roof is mounted a central operating shaft 4 journaled in suitable bearings 5 on said truss members. At intervals along the shaft, and in line with each pair of opposite ventilating windows 6, cords or wire ropes 7 and 8 extend between the sashes and around the shaft 4, preferably in several turns, which by means of metal rods 9, 9, and 10, 10 are connected respectively to the upper and lower rails of the sashes as shown, although it is to be understood that the rods may, if desired, be omitted and the ropes eX- tend to and be fastened directly to the sashes.

To provide for the simultaneous opening and closing of the sashes on opposite sides of the roof, the cord 7 passes from the rod 9 at tached to the u per end of the sash over and around the shafit) and to the rod 9 attached to the lower end thereof, whereas cord 8 passes from the rod 10 attached to the u per end of its sash, beneath and around the s aft and to Specification of Letters Patent.

Application filed January 18, 1907.

Patented Oct. 20, 1908.

Serial No. 352,957.

' the rod 10attached to the lower end of the sash, the free parts of the cord 8 crossing at 1l whereby revolution of shaft 4 in one `direction will cause the simultaneous opening of the opposite sashes, while opposite rotation of the shaft will close the sashes,

To maintain the proper tension on the operating cords to hold the sashes steady, the lower parts of the cords are provided, preferably at the junction with the rods 9 and 10, with Weights 13, attached thereto in any suitable manner, by means of which the slack is taken up and the cords maintained at an equal and uniform tension. These weights moreover cause the lower ends of the sashes t0 be drawn tightly into their frames when the sashes are closed. A further function performed by the weights 13 is to maintainL the coils of the cords tight upon the drum 4 in order to insure positive operation of the sashes under normal conditions.

The tension of the cords around the shaft is such, however, that should one or more of the sashes be prevented from moving by the clogging of snow or otherwise, the cords thereof may slip upon the shaft thus permitting the shaft 4 to rotate at all times to open and close the remaining sashes.

To operate the mechanism from any convenient point, such as the floor of the building, the shaft 4is provided at either end, and

if desired at intermediate points, with pulleys 14 around which pass hand operating ropes or chains 15 which may extend to the floor or other convenient point of operation.

In the form of my invention illustrated in Fig. 2 of the drawings, the arrangement of the shaft 16, pulley 17, and hand rope 18 may be the same as that shown in Fig. l. In this form of the invention however the sashes are operated by means of chains 19 and 20 respectively which pass around sprocket wheels 21, arranged upon the shaft `16 opposite each pair of sashes 22 to be operated The arrangement of the chains is similar to that of the cords in the former constructions to insure simultaneous opening and closing of the opposite sashes. To avoid interference of the free parts of the chains 20 at the point of crossing, the ends thereof may be attached to the upper and lower ends of thel sashes at points slightly out of vertical alinement. In this construction also the weights 23 are provided to insure the tight closing and uniform movement of the sashes in opening and closing.

lIO

Various Changes may be made in the arrangement of the parts without departing from the spirit and scope of the invention.

Claims.

1. In ventilator sash operating mechanism, the combination of a rotatable shaft and means to operate the same, flexible connections between said shaft and sash and auto matie tensioning means on said flexible oonnections to maintain uniform tension on said connections and to insure uniform opening and closing movement, and the tight closing of said sash.

2'. ln ventilator sash operating mechanism, the combination of a rotatable shaft and means to operate the same, 'flexible oonneotions between said shaft and sash and weight attached to said flexible connections to 1naintain uniform tension on said connections and toinsure uniform opening and closing movement, and the tight Closing of said sash.

3. In ventilator .sash operating mechanism, the combination of a plurality of sashes and an operating shaft common thereto of iiexible connections between said sashes and shaft7 automatic tensioning means on said connections to maintain uniform tension on said connections, said connections also adapted and arranged to permit one or more of said sashes to remain stationary while the others are moved to open or closed positions.

n testimony whereof' I afIiX my signature in the presence of two witnesses.

FRANK D. Moon.

Vitnesses M. D. HART, RALPH C. POWELL.

It is hereby certified that in Letters Patentl No. 901,544, granted October 20, 1908,

upon the application of Flank D. Moon, of Edgewater, New Jersey, for an improvement Ventilator-Sash Mechanism, errors appear requiring the following corrections: In the drawings forming a part of said patent Fig. 1 should read Fig. 2, and Fig. 2 should read Fig. 1; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Ofhce.

Signed and sealed this 24th day of November, A. D., 1908.
