FAN SUPPORT Filed Feb. 2, 1940 2 Sheets-Sheet 2 awe/whom we alihey Patented Mar. 17, 1942 FAN SUPPORT Wealthey E. Fey, Rahway, N. J., assignor to The Singer Manufacturing Company, Elizabeth, N. J a corporation of New Jersey Application February 2, 1940, Serial No. 316,876

2 Claims.

This invention relates to electric fans and more particularly to fans for outdoor use and has for its objective the provision of an improved support for the fan, and improved means for clamping the fan to the support.

The invention will be readily understood from the following detailed description in connection with the accompanying drawings, in which:

Figure 1 is a perspective View of the fan and its support.

Figure 2 is a fragmentary view of the support and the means for clamping the fan to the support, the clamping means and part of the support being shown in section.

Figure 3 is a rear elevation of the clamping means and the horizontal tube to which the motor is clamped.

In the selected embodiment Ill represents a square shaped base having one end of each of the inclined bars II and I2 welded thereto at its corners. The upper ends of the bars I2 are welded to the bars H and a horizontal rod in the form of a tube I3 is supported by the upper ends of the bars I I.

The fan motor I4 which drives the blade I5 is carried by the plate IE, to which it is secured by the bolts H. The plate I6 is formed with two downwardly extending ears I8 which are apertured to receive the horizontal tube I3. To frictionally hold the fan in its adjusted position relative to its base I have provided two blocks 20 and 2| which are located on opposite sides of the rod or tube l3 and each is formed with a chamfered surface 23 which engages the rod l3, and a flat face 24 which engages the under side of the plate IS.

The blocks 20 and 2| are apertured to receive a bolt 25 which extends through the blocks. The blocks are adapted to be drawn together by the nut 26 threaded on the bolt 25. A lock-nut 21 is provided to lock the nut 26 in position. From the above it will be observed that the nuts 26 and 2'! may be loosened to permit the blocks to separate slightly and the fan and its base adjusted to different angular positions about the tube I 3. The nuts may then be tightened to lock the fan in its adjusted position.

To limit the swinging movement of the fan and its base about the tube I3 a lug 28 is welded to the tube I3 and the ends of the lugs are arranged to be engaged by either the block 20 or 2|. Lugs 29 are also provided to prevent the cars from shifting laterally on the tube I3.

The fan is particularly adapted for cooling transformers and is used out of doors. Its angular position is usually adjusted so that the fan is directed upwardly, its normal position being substantially as indicated in dotted lines in Figure 2. It will be seen from Figure 2 that the ears I8 are attached to one end of the plate I6 so that when the fan is in its normal position its center of gravity is in a vertical plane intersecting the tube I3. This construction reduces the tendency of the fan to turn about the tube I3 as a pivot. Holders 30, are fixed to the bars I2 about which the electrical conductor cord may be wound when the fan is being transported from place to place.

Having thus set forth the nature of the invention, what I claim herein is:

1. A support for an electric fan comprising a base, a horizontally disposed rod supported by said base, a supporting plate having depending members which embrace said rod, blocks interposed between said rod and said plate and having faces in contact with the rod and plate, means for adjusting said blocks to cause them to grip the rod and prevent the plate from turning on said rod, and a stop lug carried by said rod and in position to be engaged by either of said blocks for limiting the movement of said plate relative to said rod.

2. A support for an electric fan comprising a base, a horizontal rod supported by said base, a supporting plate formed with depending ears which are apertured to receive said rod, a pair of blocks interposed between said rod and said plate, each of said blocks having a chamfered.

surface which engages the rod, adjusting means extending through said blocks for the purpose of drawing said blocks together to cause the chamfered surface on the blocks to frictionally engage said rod, a stop fixed to said rod for limiting the movement of said plate about the longitudinal axis of the rod and stop lugs fixed to said rod and cooperating with the depending ears formed on the plate for preventing lateral shifting movement of said plate relative to said rod.
