Application filed November 7, 1912. Serial No. 729,961.
the fan automatically travels as it operates and automatically reverses ,the direction of its travel, whereby one fan can ventilata a large room by traveling from one end to.
the other thereof, to and fr0, or around the room wherever the track of the fan may be arranged. Such an arrangement causes one fan to do the work of many stationary fans and will keep the air in the room pure and it can be arranged to suit a room of any size or to pass to any part of the room. Furthermore, the fan can be stopped at any point, when desired, and arranged to operate like a stationary fan.
The chief feature of the invention coni sists in the idea of suspending the fan on a track so that it can travel, and setting the fan at a slight angle from a horizontal position so that the fan will not only blow air downward, but, by reason of the angular; position, will blow itself backward and caueeitself to travel. The speed of travel,
Aas well as the degree of tanning downward,
may be varied by changing slightly the angle of the fan.
The nature of the invention will be un dex-stood from the accompanying drawings and the gfollowing description and claims: linthe drawings, .Figure 1 'is a side elevation of such fa device with the track broken away at two points Fig. 2 isla section on the line i2'2 of' -Fig. 1, sho'wlng parts in plan also. Fig. '3 is an enlarged section on the line-3-3 of Fig. 2. Flg. 4 is a side elevation of a modified form, the hanger being shown .in section. Fig. 5 is aside elevation of another modified form, the lower part of the motor and the `an being broken away. v Y
1n the form shown herein in Figs. lto 3, lthere is 'a track 10 consistin of a wire ta'etched between walls 1-1. T track 1s shown ibroken away `between its ends and it may be of term desired, and electric Patented Nov. 1s, 1913.
current is brought to it over a wire 12. A.
companion wire 13 is located above the track 10 and parallel therewith and current goes out through it over a wire 14.' It is immaterial as to which vof the wiresv 12 or 14 the current enters through. The fan mounted on'a n electric motor 16 and sai motor 1s carried in a U-shaped hanger 17 1n whlch 1t isclamped by clamps 18 .so that tionv from a horizontal position, as shown. The hanger 17 is rotatably mounted in a. frame 20 suspended from a pair of wheels 21.
The current from the track 10 passes 415 is of usual type of electrlc fans, being the fan can be set at any desired inclinathrough the wheels 21 and frame 20 and Y hanger 17 to the motor and leaves the motor through a wire 22 which is secured to the frame 20 and insulated therefrom and there is an upward extension 23 on one end of the frame 20 which projects rather close to the wine 13 and it carries a brush 24 adapted to engage .the wire 13 and it is connected with the wire 22.
When the current is turned on and the `fan operated, it `will automatically travel by reason of its inclined position, as it will push itself in the direction indicated by the arrow in Fig. 1. At the same time V1t willoperate asa fan. By increasing the inclination, the fan will travel faster, or by decreasing it, it will travel more slowly. This is accomplished b the clamp 18 for the hanger 17 is hel vertically by the frame 20.
The fan is automatically reversed by the stop blocks 30 which are secured to the ends of the track 10 or -at any .place on the track desired. The fan travels until one of the stop blocks 30 engages a sliding Ybar 31 which is slidably mounted u on the frame 20, as seen in Fig. 2, and w ch has upon one side a rack 32 which en' ages .a pinion 33 secured upon the up er en of the hanger 17. The upper end o the hanger 17 projects through a longitudinal slot 34 in the plate 31 and in that way the rack and pinion are held together in mesh, and they are made of such dimensions that onemove'- ment of the rack 31 will give the Yfan and motor a substantially hal revolution and then the fan will automatically travel in the other direction until the other end of the plate 31 carlying the rack engages the other stop 30 an thus causes a return half revolution of the fan and motor so that'the fan will again travel in the other direction.
' Stops 132 limit the action of the rack.
If it be desired to stop the fan in any position, this is done by a cam lever 35 which is pivoted at 36 to a projection 37 from the frame 20, see Fig. 3, and when operated to the full line position, it clamps the frame 20 to the track 10 and when operated to the dotted line position, it disengages from said parts so that the fan will travel. In th1s way thc fan can be locked in any position and serve, for the time being, as a stationary fan.
In the m'odiied form shown in Fig. 4, the device is simplified, the fan and motor being merely suspended by two wires 40 and 41 which permit the fan and motor to turn at each end of the travel. There is only one wheel 21 in this form and it is carried in a frame 42 which is much smaller and simpler than the frame 20, having a lower portion in which the wire 40 is held and suspended so t-hat the current coming in through the track 10 goes to the motor through this wire 40 and current goes out from the motor throu h wire 41 and the Wire 13, the upper end o the wire 41 being held by a plate 43 on the upper end of the frame 40 so that said wire 41 will brush the wire 13. The clamp 35 is mounted on the frame 46 so that it engages the track the same as has been eX- plained.
In the m'odiied form shown in Fig. 4, no reversing mechanism is employed, but the fan is merely set at an angle by the clamps 18 so that its inclination from the horizontal position will cause it to travel in one direction until the frame 42 strikes a stop 30 and then the device will stop traveling for a moment, but the fan Will keep operating and in a moment will turn about half way until the frame 42 starts to travel in the other direction so as to relieve the fan and then it will keep traveling that way and in that position until the frame 42 strikes the other stop 30, whereupon the fan will automatically turn again until the frame starts to travel again in the opposite direction and relieve the fan. This form is much simpler than the one shown in Figs. 1 to 3, and will operate, but not with the positiveness of the preceding form.-
In the modified form shown in Fig. 5 there is a frame 20 substantially like that shown in Fig. 1, but it has two brace bars 50 eX- tending down from it carrying a bearing 5l in which a shaft 52 is mounted which carries the motor 16. This shaft extends through the bearing 51 and also through the frame 20 and has a washer or plate 53 on top for supporting it. In this form the wire 22 is mounted substantially as in Fig. 1 and brushes against the Wire 13, but the lower end of that wire brushes against a disk 54 insulated from the other parts of the motor and connected with the motor so that the current to the motor will come through rod 52 and the current from the motor will pass out through disk 54 and wire 22. Insulation is shown at ,55. The reversing mechanism is omitted from the drawings in Fig. 5, but it is substantially-the same as that in Fig. 1.
The invention is not limited to any particular details of construction, such. as are shown herein, the chief feature being the mounting of an electric fan sothat it can be set at an inclination from the horizontal position and thus be caused to automatically travel, and in the second place, the provision of stops or other means to cause it to reverse its direction of travel.
