FAN WITH COLLAPSIBLE SUPPORT Filed April 21, 1957 Patented Nov. 30, 1937 UNITED STATES PATENT orr cr FAN WITH COLLAPSIBLE SUPPORT Application April 21,
7 Claims.
This invention relates to fans with collapsible supports.
It is the general object of the invention to provide a novel and improved electric fan of cheap and simple construction which can be used either as a pusher or puller fan, can be supported on a flat support with the fan directed at various angles,-can be hung or supported invarious other manners and the support of which can be collapsed sothat the fan with its support may be stowed away in very small compass.
The objects and advantages of the invention will more fully appear in the following description, made in connection with the accompanying drawing, in which like reference characters refer to the same or similar parts throughout the various views, and, in which,
Fig. 1 is a perspective View of the fan as it will appear when the fan blade is substantially vertical and the support is extended to hold the fan in position on a horizontal surface;
Fig. 2 is a view in front elevation of the fan in the condition shown in Fig. 1;
Fig. 3 is a view in side elevation of the fan, the fan being shown in full lines in the same condition as shown in Figs. 1 and 2, and being shown in dotted lines in a different position relative to its support;
Fig. 4 is a view in side elevation showing the fan with its support collapsed; and
Fig 5 is a horizontal section taken on the line 55 of Fig. 2, as indicated by the arrows.
In accordance with the invention there is provided an electric motor 6 of substantially cylindrical shape from the forward end of which the motor shaft I projects. Attached to the forward part of the shaft 1 is a fan blade 8. This blade in the illustrated embodiment has two arms and in order that the fan may have a good suction action as well as a good propulsion action the arms of the blade 8 are made of uniform width from adjacent the tips of the arms to a central non-pitched portion of the blade. The two screws or studs 9 holding the parts of the stator of the motor 6 in assembled relation project forwardly somewhat from the front of the motor and are equipped with the usual nuts II] bearing against the front of the motor and they are also equipped with washers II and nuts I2 outwardly from the nuts ID. A guard cage I3 made up chiefly of wire surrounds the fan blade 8 and the rear central part of this guard cage is equipped with two circular wires I3a and I3b respectively arranged in concentric relation in the same plane. The spacing between the two circular wires I3a 1937, Serial No. 138,172
and I31) is less than the width of the nuts I6 and washers II' and the forward ends of the screws 9 are reoeivedbetween the wires I3a and I31) and the nuts I2 and washers II are used for securely clamping these wires against the nuts It. This affords an extremely simple and inexpensive construction for attaching thecage I3 to the motor 6 and at the same time it permits of rotative adjustment of the cage I3 relative to the motor 6 during assembly to'permit the parts of the cage to be symmetrically arranged.
A clamping band I4 fits about the circular wall of the motor 6 and is'provided with normally downwardly extending apertured ears through which a wing 'nut equipped'bolt 'I 5 extends. A fiher sleeve 'lii bestshown in-Fig. 5, fits about the bolt I5 between the ears of the clamping collar I4 for the purpose of producing a frictional pivot joint as-will presently appear.
--The support for-the fan is designated as an entirety by the letter S and it consists of a single This peculiar construction of pivot joint includ- T ing' the fiber sleeve It produces a simple type of frictional pivotal joint, permitting the support to be readily swung 'on the bolt I5 as its axis to various positions relative to. the motor 6, blade 8 and cage l 3 but at the same time exerting sufficient frictional resistance to the swinging movement to cause thesupport S and the motor 5, blade-8 and cage '1 to retain their relative positions when the desired positioning has been obtained.
' From the eyes I? the wire forming the support Sis extended'--'down wardly 'fona. short distance to form short downwardly extending portions I8 whereupon'the .wire'is bent outwardly from the portions It to form stop shoulders I 9 and out- As viewed in v,
side elevation as shown in Figs. 3 and 4, a space 23 is afforded between the downwardly and rearwardly extending portions 2! and the foot 22 for reception of portions of the cage l3. Mounted on the foot 22 is a forward and two lateral grooved sleeves 24 composed of rubber or other resilient and frictional material, these sleeves being provided for the triple purpose of preventing the fan, due to its vibrations, from creeping when it is being supported upon a surface such as a table or the like, preventing the fan from transmitting vibrations to its supporting surface and protecting the surface from marring or scratching by reason of the supporting foot 22 resting thereon. The grooves of these sleeves are designated by the numeral 24a.
It will be seen that when the support S is extended from the cage l3 of the fan, the fan may be supported stably upon a suitable supporting surface and that the fan blade 8 can be set at almost any desired inclination relative to the horizontal to direct air in almost any desired direction or to cause air to be sucked into the fan from almost any desired direction. In Figs. 1, 2 and 3 in full lines the fan blade 8 is shown located in a vertical plane while in dotted lines Fig. 3, the motor 6, cage l3 and blade 8 have been swung rearwardly and downwardly to an inclined position relative to the support S. In this latter dotted position the shoulders l9 act as stops against the motor 6 to prevent further downward swinging movement. While in the drawing the fan is shown as being supported upon a supporting surface, such as a table or the like, it will be readily seen that the fan can be readily hung as from a nail, hook, bracket or the like mounted on a vertical or other wall so as to be suspended from what is the forwardmost portion of the foot 24 as viewed in Fig. 3 with the foot bearing against the wall.
To collapse the support S, it is merely necessary to swing the parts to the position shown in Fig. 4 whereupon a portion of the cage l3 will be received within the space 23 and the foot 22 will lie closely against the normally forward side of the cage. In this position the fan with its support takes up but small space and it can be stowed away readily as in a suit case or the like. Of course when the stand is in a collapsed position, it can be hung as from a nail or other sup port attached to a wall, window or the like in such relation that the fan may be used either as a suction fan or a propeller type fan. For example, the fan may be supported as from a nail in an open window by hooking either the foot 22 or the cage l3 onto the nail and if it is desired to draw fresh air into the room the fan may be faced inwardly, while if it is desired to suck air out of the room the fan may be faced outwardly.
Attention should be called to the fact that the downwardly and rearwardly extending portions 2| form a convenient handle which can be grasped for moving the fan from one position to another. The portions 2| and the foot 24 form a hook which permits the support S to be hooked as over a chair back or the like for proper support of the fan. 7
The motor 6 is preferably equipped with an electric switch 25 and an electrical conduit 26 and a socket plug 21 for connection with a source of electrical supply.
It will be seen that an extremely simple and efficient fan has been provided which is capable of being effectively used to direct air in praccage attached to said motor and surrounding said blade and on oppositely reversely curved bail-like support swingably connected to said motor, said support having a foot and an arm extending therefrom to said motor, said arm and foot as viewed in side elevation cooperating to form a space within which the lower portion of the cage may be closely received with the foot lying adjacent the forward side of the cage when the support is swung to one position and said foot acting to stably support said motor, blade and cage on a supporting surface at various inclinations when the support has been swung to other positions.
