oscILLATING MECHANISM FOR ELECTRIC FANS.
Specification of Letters Patent. I Patented uly 1920,
Application filed May 7, 1919. Seria1 No.295,341.
To' all whom it may concern:
Beit known that we, WILLIAM G. WVINTER and HERBERT I. FINCH, citizens of the United States, residing at the city of St. Louis, State of Missouri, haveinvented a certain new and useful Improvement in Oscillating Mechanism. for Electric'Fans, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. Y 1
This invention relates to a certain new and useful improvement in oscillating mechanism for electric fans, and particularly to the means for adjusting said oscillating mechanism, being designed particularly as an improvement upon. United States Letters Patent No. 1,256,121, granted to Herbert I. Finch and Thomas M. Meston under date of February 12, 1918. v y In this invention the oscillatory movement of the fan may be varied or eliminated, as desired, and said adjustment can bemade while the fan is in operation or stationary. The principal object of this invention is to provide a simple and easily adjustable oscil- 'lating mechanism having few parts and which can be economically manufactured. Various other objects of our invention will be obvious, or pointed out hereinafter, refer: ence being made to the accompanying drawings," in which: g
Figure 1 is a rear elevation of the fan motor and .a vertical cross-section through the oscillating mechanism for said fan. Fig. 2 is a side elevation of the motor and a vertical cross-section ofthe oscillating mechanism taken'at right angles to Fig. 1.
Fig. 3 is a horizontal cross section taken approximately on. line o,3 of Fig. 1.
' ig..4,is a top plan view of the adjusting device. 3
Fig. 5 is a detail perspective view of the rotary member.
Fig. 6 isa detail perspective view of the adjustable block.
Fig. 7 isa perspective of the casing or cap piece. Y f
Fig. 8 is a detail view ofa pivotal member carried by the adjustable block.
Fig. 9 isla vertical cross-section through the adjusting'device and showing means for retaining the casing inzits adjusted position on the rotary member.
,8 through which the shank of screw 7 passes.
Referring to the drawings, M indicates a motor mounted forrotary movement. on a stationary'base Band provided with a .fan 1n the usual manner.v Carried by said motor is a suitable housingl in which is located a I reduction gearing 2 operatively' connected with the rotor shaft of motor M'and having a shaft 4 to which is fixed rotary member 5.
Thelower face of'the rotary member is provided with a'transverse groove 5 designed to accommodate an adjustableblock 6 whose shape, is such as to permit of its sliding movementlongitudinally in groove 5 across 7 the axls of the rotary, member 5. Formed in the adjustable block 6 is a slot 6, and fixed to said block is a pin or screw'7. Block 6 is retained in groove 5 by easing or cap piece'8 havlng an upwardly extending flange 8 wh ch 1s knurled or roughened and surrounds and engages the annular flange 5* on;
Screw 7 acts as a pivotal mounting for one end of link 9, the other end of which is pivotally connected to the stationary support on base B. The cap piece 8 is looselycar'ried by member 5 and is adapted to be manually rotated around said member 5, the annular flange 5 providing a bearing surface for the inwardly turned edge of the upwardly extending flange 8 of cap piece 8.
The} arrangement of p1n 8 on; the: cap
piece, and slot 6*, in block 6, is suchJthat the 7 rotation of the cap piece in one direction will move block 6 and screw 7 toward theaxis of the rotary member androtation of the cap piece in; the opposite direction will cause, the
- helps to maintain it in its adjusted position. In the operation of our device, the rotary. -motionof the1roton shaftis transmitted by the reduction gearing to shaft 14 and rotary member 5. The rotary motion of the rotary member will exert pull and thrust moments on-the link and willcause the link, piyotally connected to the station- ;fan will cease. V r a r I In assembling our device, the adjustable block is positioned in the longitudinal groove of the'rotary member, and the cap ary base to move inan'arc concentric with the stationary pivotof said link thereby causing the rotary member itself and the 'moto'r rotatably mounted in the stationary base and supporting the housing of the rotary member, to oscillate.
from the axis of the rotary member. WVhen the screw 7 on block 6 is brought in coaxial alinementwith the axis of the rotary member, the rotary member no longer exerts any pullland thrust moments on the link and the oscillatory movement of; the
piece is placed in position with the pin carried by said cap piece arranged in theslot "in theadjustableblock; The edge of the upwardly extending flange is inwardly and downwardly CllSPOSGClSO as to'engage the annular flange-of theirotary member and thereby hold the cap-"piece rotatably on the rotary memberand retain the adjustable block in the longitudinal groove. v
The device when assembled forms, a pen manent articulated mechanism wh'ich'is not 'susceptible of being tampered with and placed out ofcommission; The block 6 is 'adjustablegin a straight radial' movement lengthwise of the slot 5 and the pitman "pin carried thereby may be adjusted toward and from the center of the'axis of rota-" tion of the block 5; The knurled "edge of the rebent housing '8' is preferably formed operate with'the folded edge of the knurled housing, thus avoiding the necessity of any teeth 'or'notches forthespring.
- We donot wish to limit o'urselvesto the device described and illustrated as various modifications may, be 'made and substituted withoutfdeparting "from thespii'it of the invention" f- 'l Vhat'we claim is:
51. In "an oscillating mechanism for fans, a rotary member, means for driving the same,' anad ustable member carried in-the lower end of said rotary member, means pivotally connecting saidi'adjustable membeer with a stationary support, ahousing in'closing the lower end'ofjsaid rotary member 'and foldedthereover', and adapted'to r a 'rotarymember-havinga transverse slot move said adjustable "member'towar'd' or away fromthe'axisof saidrotary member.
