Be it known that I, GEORGE-W. WEIss, af.
of New York, in the county of Kings and State of New York, have invented certain Fans, tion. .V .j
This invention relates to. powerfans and more particularly to'thatelass of vpower fans -of which the ollowing is aspecicafor the benefit of the operators thereof the provide a fan of the class referred to that wil be cheap in pable of being readily adjusted to direct the With such object in View, my invention y detail and pointed out inthe Referring now tothe accompanying drawings forming part of this sv eciication; Figure 1 is a rear Vside view o a fan embodyative engagement with the fly-Wheel of a is an end view of the parts shown inFig. 1, looking from the left. Figs. 3 and 4 are front and side views, respectively, of a modifiedv form of the invention. 1
A- fan embodying my invention may be located upon any suitable support and be` actuated from any suitable motive power, but the same is herein shown as being located upon a sewing machine table, indicated at 2, and as bein adapted .to be actuated from the ily-wheel of a sewing machine, indicated at 3.
The fan preferably comprises a supporting parts of the an are supported and which is adaptedto'be fixedl secured at its base to the table 2 by suitab e fastening means,- such as the screws 5. At its u perend the standard 4 is provided with aL aterally projecting arm 6 having a vertical perforation in which issu ported a verticallyand rotatably ad-' Specicationiof Letters Patent. v.pplnmtimn mea my s, 190e. semi No. 315,383.
justa e stem 7 having at its 'upper end a Patented June 2, 190s.
substantially U-shaped bracket 8 in which is journaled a shaft 9 having iixedly attached thereto a fan 10. With such described adj ustable 'connection between the stem l7 of the fan-carrying bracket andthe standard 4the 'fan 10 may be adjusted vertically, and also angularly 1n a horlz'ontal plane, to direct the current of air created thereby` in a desired direction with respect tothe operator of the machine or other erson using the same, and after the fan has een adjusted to a desired position, it will then'be held stationary in Such position by suitable `fastening means, such as the set-screw 12 in the standard '4 engagng the stem 7. A
The adjustment of the fan as described is sufficient under all ordinary conditions, but in some instances it may be desirable to have an angular adjustment of the same in a verl ticalplane, and in order to provide for this I form the'stem, as shown inr Figs. 3 and 4,
with an extension 14 having aliorizontally arran ed end 15 upon lwhich a fan-shaft-car oscillating movement in a vertical plane, the
lsaid bracket being adapted `to be held instationary'adjusted position relative to its'su porting stem by means of a set-screw 17 j! As a means for driving the fan, I have joug.'- naled a shaft 20 in a bracket 21 Amounted on the standard, below its upper end, which shaft isprovided with a friction-disk'or pulley 22 for en agement with a suitable motor,
such as the y-wheel 3 of a scanne-machine,-
ryingracket 16 is mounted to be capable of and is belted' to the fan-carrying shaft 9lby a belt 23 passing over grooved belt-pulleys -24 located on the respective shafts as shown.Jv y The said belt 23 may be made of elastic material if desired so as to be self-adjustin to any change in the vertical position of the a ,carr mg shaft 9, butordlnarily I prefer to a non-elastic belt, which event I emp o rovi e a means forautomatically controling' the slack in the belt u on' any changem positionvof the f an being e ected, such meansy as herein shown comprls'ing a s ring arm 26 attached at one end to the brac ,et.21, as at 27 andat its opposite end carrying a pulley 'ibo 28 for engagement with the belt'at a `point intermediate of thebelt-pulleys 24 as shown. It will -De seen that'by this structure, the
vbelt is always maintained taut as the pulleys i,
28 and 22are in substantiallyfixed relation lto each other, lso that movement'of the'pul-fk atiye `have pivoted the bracket 21 to the standard lley 22, when. adjusted, in no way tends to slacken the belt, as would be the case were the pulley 28 secured to the standard or in some other position permitting substantial relative movement between the pulleys.
' In order that the friction-disk or pulley 22 may be readily moved to and from an o erosition of contact with the fly-w reel 3 .of't emachine whereby the fan will be" caused to either operate or be stationary, I
at and located an adjusting-screw 31 in v the standard in a position to have the bracket stated.
yieldingly, held against one end thereof by means of a spring, as indicated at 32. With this arrangement and combination of parts, a mere turning of the screw 81 in the proper direction will cause the friction-disk 22 to be moved either to or from a position of engagement with the fly-wheel 3 for the purpose 'What I claim is: 1. A power fan comprising a supporting standard, a bracket rotatably mounted thereon for adjustment in a horizontal plane, a fan operating shaft journaled on said bracket, a second, bracket pivotally supported on the .-standard, a driving shaft journaled on said bracket and geared to the fan operating shaft, means on said driving shaft to receive rot/atory movement, a spring to move said pivoted bracket in one direction, and means to move itin another direction against the force j o f the spring.
, spring, and a spring actuated pulley mounted Aon said second bracket and engaging said belt to maintain automatically the same taut irrespective of the adjustment of said bracket.
3. A power fan comprising a rsupporting standard, a fan carrying shaft journaled at the upper portion thereof and means whereby it is adjustable with relation thereto into different angular positions, a bracket movably mounted on the standard at a point belwsaid shaft'themovement of said bracket being independent of the adjustment of the fan carrying shaft, a driving shaft journaled on said bracket and geared to drive the fan carrying shaft, a spring to move the bracket in one direction, and means to move it in another direction against the force of the spring.
4. In a power fan, a standard, a bracket rotatably mounted thereon for adjustment in a horizontal plane, a horizontal extension to said bracket, a sleeve mounted on said eX- tension, a fan vshaft journaled on the sleeve, said sleeve being rotatable about said extension to permit adjustment of the fan shaft in a vertical plane, and means for securing said sleeve in adjusted position.
5. A power fan, comprising a supporting standard, a rotary shaft having a fan attached thereto, abracket carrying said shaft and having an adjustable connection with the standard said connection permitting adjustment independent of the fan carrying shaft, a bracket pivotally connected to the standard, a driving shaft carried by said bracket and having a pulley for engagement with an actuating part, a belt operatively connecting said driving shaft with the fancarrying shaft, and means comprising a spring and an adjustable screw for moving the said bracket to shift the pulley of the supported driving shaft to and from an operative position for engagement with its actuating part.
