ToaZZ whom it may concern. p
Be it known that 1,:JOHN A. -EDMAN, a citizen of the United States, residing at New Haven, in th'ecounty of New Haven and State of Connecticut, havei.-invented a new andnseful Improvement in Bases for Electric Fans; andI do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, toabe. a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in,
Figure 1 a top or plan view'of a base for electric fans constructed in accordance with my invention.
Fig. 2 a transverse sectional view of the same.
Fig. 3 a top or plan view indicating an electric fan as mounted upon the fan plate and showing the fan plate eccentrically connected with the base plate.
This invention relates to an improvement in bases for electricians. In the more general arrangement of supports for electric fans, they are adapted to turn in one direction to a certain distance, and then in the opposite direction. 3
The object of this invention is to provide a base upon which an electric fan may be mounted and which may make a complete revolution caused by the motion of the fan; and the invention consists in certain details of construction as will be hereinafter described and particularly recited in the claims.
In carrying out my invention I employ a base 5 of any suitable design, preferably round, so as to, provide an annular wall 6,
and the base is also formed with a centrally arranged tubular bearing? formed in its upper end with a runway 8 for anti-friction balls 9. In connection with this base I employ a base plate 10 preferably round, and corresponding in diameter to the wall 6 and formed with a centrallyarranged post 11 the lower end 12 of which enters an opening or recess 13 formed for it in thebottom of the base 5, and near its upper end with a runway 14 for the balls-9, and so that the base plate is adapted to freely revolve in the base. Arou'ndthe ost and insulated therefrom are two ban s 15 and 16 with which brushes 17 and18 contact, these brushes being connected by wires 19 and 20 for elec- Specificationv of Letters Patent.
Application filed July 2, 1919. Serial No. 308,290.
Patented Nev. 25, 1919.
trical engagement with a plug 21'mou-nted in one sideof the base and through which a connection with electric power wires22 and 23 may be made.v The rings15 andl6 are also connected to wires 24 and 25 by which electrical connection may be made with 'a screw plug 26 carrying wires 27 and; 28 which lead to the motor 29 of an electric fan. Superimposed-upon the base plate 10 is a fanp'late 30 which is provided with clamps 31 by which the base 32 of a fan may be connected with the fan plate. This fan plate is connected with the base plate 10 through the plug 26 so that the fan plate is eccentrically pivoted to the base plate.
The fan plate is formed with a tangential slot 33 through which a bolt 34 extends, the bolt being mounted in the base plate and provided with a thumb nut 35 by which the fan plate may be clamped to the base plate in various positions, the slot 33 being concentric with the pivotal point of the fan plate.
The fan being applied to the fan plate and electrically connected so as to be driven, will, by the impingement of the blades against the air, force the fan plate, and hence the base plate, to revolve, and the rapidity of revolution may be regulated by adjusting the fan plate on the base plate, as it is obvious that if the fan plate is concentric with the base plate, the fan will not revolve, but when the fan plate is moved so that the center of the fan is moved away from the center of the base plate, the base plate will be caused to revolve.
I claim 1. A base for electric fans comprising a base provided with a central bearing, a base plate formed with a central post seated in said bearing, said post provided with insulated bands, brushes in contact with said bands, said brushes connected with the source of electrical supply, wires connected with said bands and leading to a plug mounted in the base plate, a fan plate eccentrically pivoted to the base plate and adapted to be adjustably secured thereto.
. 2 A base for electric fans comprising a base formed with a central bearing, a base plate formed with a centrally arranged post seated in said bearing, said post provided with metal bands insulated from the base,
brushes in the path of said bands and in en-' gagement therewith, a screw plug mounted in said base and in electrical connection with said brushes, a screw plug mounted in said base j plate and electrically, connected I a upon said base plate and conneoted'thereto by the with said bands, a fan plate resting plug in the base plate, means for a an electric fan to said fan plate, and means for adjusting the fan plate vwith relation to the base plate. V a
'3. A base for electric fans comprising a base formed with a central bearing having a runway, a base plate formed with a central .post'having a runway and supported at its lower end in said base,anti-friction balls in saidrunways, metal bands surrounding said v post and insulated therefrom, brushes mounted in a central bearing and contacting a :with said bands, a plug connected-with the power wires and mounted in one side of the base. and electrically connected with said brushes, a screw plug mounted in the base plate and electrically connected with said bands,afan plate resting on said base plate bolt mounted in the base plate and extending through said slot, and a nut onsaid'Tplate for clamping the fan plate to the base plate. In testimony whereof, I have signed this specification in theipresence of two su'bscribingtwitnesses.
