COMBINED CHANDELIER AND ROTATING FAN.

SPECIFICATION forming part of Letters Patent No. 332,821, dated December 22, 1885.

Application filed September, 18, 1885. Serial No. 177,4l6A (No model.)

To @ZZ whom t may concern,.-

Be it known that I, PETER MURRAY, Jr., of Newark, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in a Combined Chandelier and Rotating Fan, of which the following is a specication.

This invention relates to a combined chandelier and rotating fan, in which the frame [o and gas-tubes of the chandelier are used as a hanger-frame for the shafts by which rotary motion is imparted to the fan; and the invention consists, first, of a novel construction of the chandelier; secondly, ofthe arrangement of the fan-.shaft at the center of the same; and,l

thirdly, of a friction-disk transmission, by

which rotary motion is transmitted from the driving-shaft to the anshaft, as will be more v fully described hereinafter, and nally pointed 2o out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved chandelier and rotating fan. Fig. 2 is a vertical central section of the same, drawn on a larger scale, and Figs. 3 and 4 are details, showing the means by which the speed of the rotating fan-shaft is varied and thrown in or out of motion.

Similar letters of reference indicate correspending parts.

In my combined chandelier and rotating fan lthe frame and gas-tubes of the chandelier are so constructed that they Aserve as ahangerframe for supporting the horizontal driving- 3 5 shaft and the vertical fan-shaft, which latter is located centrally to said hanger-frame. The lower part of the hanger-frame has to be so arranged that it can be turned axially on the stationary top part of the same, so that the 4o gas-tubes can be adjusted to any position of the driving-shaft without interfering with the same.

The hanger-frame consists of a ring-shaped top part, A, and an axiallyadjustable lower part, G. The top part, A, is attached by a center bolt, or in any other suitable manner, to the ceiling. It is provided at its lower part with a ring shaped section, A', having circumferential flanges b b, to which the upper 5o ring-shaped section, B, of the lower part, C,

its upper end with a journal-bearing for the driving-shaft D, that passes belowthe upper section, B, through the lower part, C, of the hanger-frame. The middle section, B', serves also as a support for the vertical fau-shaft E,

which rests by a xed collar, e, on a central v depression, e', of the middle section, B'. The vertical fan-shaft E turns in a bearing, e2, at the center of the middle section, B', and on a central bearing, e3, of the lower section, B2, of the hangerframe, as shown clearly in Fig. 2. The sections B B B2 are rigidly attached to the gas-tubes C C, so as to form a strong frame for supporting the driving-shaft D and fan-shaft E.

To the lower ends of the gas-tubes are applied the gas-burners and globes, as customary in gasoliers. The arms of the chandelier may also be provided with incandescent electric lamps and suitable conductingwires, in-

case the same is to be used as an electrolier.

To the lower end of the shaft E is keyed the hub of a Ventilating-fan, F, the blades of which are inclined in such a manner that the airis forced in downward direction away from the lights, so that they are not affected by the air set in motion by the fan.

To the driving-shaft D is splined a frictiondisk, f, while a second friction-disk, f', is applied loosely to the upper end of the fan-shaft E, at right angles to the disk f, which is provided with a central depression, f2. The disk f is adapted to be clutched to or unclutched from the fan-shaft E by means of an adjustable handle-rod, E', that passes longitudinally through the tubular fan-shaft E to the upper end of the same. The upper end of the handle-rod E is connected by a pin, g, with the hub of the friction-disk f', said pin passing ICC through a vertical slot, g', of the tubular fanshaft E, which slot is provided at one side with rack-shaped recesses gz for the pin g, as shown in detail in Figs. 3 and 4. By taking hold of the lower end of the handle-rod E the connecting-pin g is moved out of its recess by the motion of the tubular fanshaft E, so that the handle-rod E', and with it the friction-disk f',

can be set higher or lower, and thereby the friction-disk f adjusted nearer to or farther away from the center of the friction-disk f. By releasing the handle-rod E the connecting-pin g engages one of the recesses of the slot and couples thereby the disk f to the fan-shaft E. By raising the handle-rod F Sufciently, so that the disk j" is in line with the depression f2 of the diskf, the fan F is stopped. By set-ting the friction-disk f to the outer part of the friction-diskf the fanshaft E is rotated slower or quicker, according to the distance of the friction-disk f from the center of the frictiondisk j'. The collar e of the fan-shaft turns on the center bearing of the middle section, B', with but slight friction, owing to the buoying action of the fan, which balances to some extent the weight of the ian-shaft and handle-rod.

In place of the mechanism by which the friction'disk f is set-that is to say, in place of the center rod and the clutch device by which it is connected with the hub of the friction-disk f-any other clutching mechanism may be used, as I do not confine myself to the special construction shown.

By the employment of friction-disks the transmitting belts and pulleys are dispensed with, which would interfere with the gas-tubes of the chandelier, and would be objectionable, owing to their unsightly appearance.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a hanger-franie'composed of a stationary top section attached to the ceiling, and a lower axially-adjustable section with a drivingfshaft, a fan-shaft carrying a fan at the lower end, and friction-disks by which rotary motion is transmitted from the driving-shaft to the fan-shaft, substantially as set forth.

2. The combination of a hanger-frame having center bearings for the fan-shaft, a drivingshaft supported on a standard of said hangerframe, a vertical fan-shaft having a fan at the lower end, and friction-disks by which rotary motion is imparted by the transmitting-shaft to the fan-shaft, substantially as set forth.

3. The combination of a hanger-frame, consisting of a stationary top section, gas-tubes, and ring-shaped sections, a driving-shaft, a Vertical fan-shaft, and friction-disks on said driving-shaft and fan-shaft, substantially as set forth.

4. The combination of a stationary hangersection attached to the ceiling, said hangersection having an annular groove or channel, an axially-adjustable hanger-section formed of ring-shaped sections, and gas-tubes communicating with said channel, the lower section being connected by a center bolt and disk to the top section, and provided with centerbearings for the vertical fan-shaft, substantially as set forth.

5. The combination of a hanger-frame, a A

driving-shaft supported by said hanger-frame, a tubular fan-shaft supported by center bearings of said hangenframe, transmit-ting friction-disks on the driving-shaft and fan-shaft, a handle-rod passing through the fan-shaft, and a clutch mechanism whereby the frictiondisk on the fan-shaft can be set higher or lower, so as to vary the speed of the fan, substantially as set forth.

6. The combination of a haugerlrame, a drivingshaft supported by said frame, a friction-disk applied to the driving-shaft and having a central depression, a tubular fanshaft supported by said hanger-frame, a fan keyed to the lower end of the fan-shaft, a friction-disk arranged loosely on the upper end of the fan-shaft, a center rod, and means for connecting the center rod with the frictiondisk of the fanshaft, so that it can be raised or lowered or placed in line with the central depression of the friction-disk of the driving# shaft, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my naine in presence of two subscribing witnesses.
