UNITEDQSTATES PATENT OFFICE.
JOHN E. MARSDEN, or PHILADELPHIA, PENNSYLVANIA.
ELECTRIC HEATER FAN.
Original application filed March-15, 1926, Serial No. 94,654. Divided and thi s application filed October 10,
Serial No. 225,189.
This invention relates to electrical apparatus and especially to ventilating fansor the like of the general nature as set forth in my copending application for combination electric heaters and fans, Serial No. 94,654, filed March 15th, 1926, now Patent No. 1,674,017 and of which this specification is a division.
Among the objects of this improvement is to provide novel mechanism for controlling automatically the lateral vibrations or oscillations of the motor driven mechanism.
lVith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details. of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation of an embodiment of the invention applied to a ventilating fan.
Fig. 2 is a horizontal sectional detail of the oscillating mechanism on the line 22 of Fig. 1.
Fig. 3 is a vertical sectional detail of the cam and clutch mechanism for the oscillating means.
Referring now more specifically to. the drawings, I show my improvement as comprisin a suitable base 10 having a pedestal 11, the base and pedestal constituting suit able housing means for the wiring connections and switches. 12 is a jack for the disconnectible attachment of a lighting circuit 13 or an equivalent source of power.
At 17 is a head connected to the upper end of the pedestal and adj ustable around a horizontal axis 18 and secured by a clamp 19, said head constituting the lower member of a turn table whose upper member 20 supports a casing 21 within which is housed a motor M having a horizontally disposed shaft 22. To one end of this shaft is secured a fan 23 The means shown herein for the lateral oscillation of the mechanism includes a pcculiar construction of clutch mechanism 35 shown in detail in Fig. 3 as comprising an upper disk 36 fixed to a vertical shaft 37, a lower washer or disk 38, an intermediate disk 39 adjacent to the disk 36 and having a series of pits 40 into which pins or studs 41 borne by the disk 36 project under normal conditions, an eccentric 42, and a, pair of disk-like Washers 43 interposed between the eccentric 42 and the respective washers or disks 38 and 39. A
series of pins 44 serve to tie the disks 39 and 43 to the eccentric, compelling all these parts to be locked together as a unit. The shaft 37 is connected to the shaft 22 by a well known type of speed reduction gear train (not shown). This gear mechanism 1s -mounted in a suitable housing 47 extending rearwardtending to stop its oscillation, the spring will permit a slip to take place between the disks 36 and 39, the studs 41 at such time riding over the smooth upper surface of the disk. 39. The eccentric 42 is circular, and surrounding it between the disks 43 is a strap 51 made as a part of aconnecting rod 52 whose forward end is pivotally attached at 53 to an arm 54 extending laterally from the head 17. The head is normally stationary and so constitutes an abutment against which the rotational effect of the eccentric serves to cause lateral oscillation of the casing and parts associated therewith around the upright axis of the turn table. In order to stop the oscillatory movement of the de vice it is only necessary to loosen the thumb nut 48, allowing the studs to rotate with the disk 36 without rotating the clutch members and eccentric. The operation of the motor is controlled by a switch 55 placed in convenient'position on the pedestal 11'.
While the casing 21 is adapted for an interchange of combination heater coil and small fan and for the substitution of them for a large fan because of the slip or bayonet joints shown, in this specification reference is made particularly to the large fan construction located within a cage 28*.
I claim:
1. In a device of the class setforth, the combination with a pedestal, a turn table mounted thereon for oscillation around a vertical axis, and a casing supported upon the turn table, of means to oscillate the casing with respect to the pedestal comprising a shaft, a disk fixed to the shaft, a stud eXtending from the face of the disk, a pair of disks mounted upon the shaft, one in contact with the first mentioned disk and having one or more pits into which the stud is adapted to project, the disks of the pair being spaced from each other, an eccentric surrounding the shaft between said disks, means to hold the eccentric to one of the disks to prevent relative rotation thereof, an eccentric strap surrounding the eccentric, a connecting rod lead ing from the strap to the upper portion of the pedestal as an abutment, and means from the casing to rotate the shaft and the first mentioned. disk.
. 2. A device as set forth in claim 1 including spring means to hold the first mentioned disk in operative contact with and for the rotation of one of the disks of the pair and providing for the'slippage of the driving connection between these parts in an emergency,
3. In, an oscillatory fan mechanism, the combination of a pedestal, a turn table sup ported thereon for rotation around a vertical axis, a portion of the turn table being stationary and constituting an abutment, a casing supported upon the turn table, a: shaft extending downward from the casing, a plurality of disks surrounding the shaft, one of which is fixed thereto, stud and pit connections between the fixed disk and the-next disk of the series, an eccentric surrounding the shaft, a pair of washers on opposite sides of the eccentric, pin means extending through said washers, said eccentric, and one of the disks for locking these four parts together for rotational purposes, a connecting rod pivotedto said abutment, and an eccentric strap surrounding the eccentric and connected to said rod whereby the rotation of the shaft and disk devices causes rotation of the eccentric and oscillation of the casing mechanism.
4. In a device of the class set forth, the combination of a fixed abutment, a turn table mounted thereon for oscillation around an axis, a shaft extending from the casing, means to rotate the shaft, a pair of disks surrounding the shaft, one of which is fixed thereto, stud and pit slip connections between the two disks whereby one is driven from the other, adjustable tension means carried by the shaft and serving to hold the two disks in driving contact with each other to permit slippage under over-strain, an eccentric surrounding the shaft adjacent to the slip disk, means to connect the eccentric to the last mentioned disk, a strap surrounding the eccentric, and a connecting rod leading from the strap to said abutment, substantially as set forth.
In testimony whereof I afiix my signature.
