Description
UNITED STATES PATENT OFFICE.
W'ILLIAM E. VILOOX, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HIMSELF ANI) BERNARD F. MYERS.
IMPROVEMENT lN FAN-POWERS.
Specification forming part of Letters Patent No. 45,447, dated December 13, 1864.
To all whom it may concerny Be it known that I, WILLIAM E. WILcoX, of St Louis, county of St. Louis, and State of Missouri, have invented a new and useful Fan-Power g and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making' a part of this specification, in which- Figure l is a perspective view of my invention arranged for operation. Fig. 2 is a sectional view of Fig. l, showing the mechanism for giving motion to the fan.
Similar letters of reference indicate corresponding parts in both figures.
The object of this invention is to provide for regulating the speed of fans which are actuated by springs or weights acting upon a train of wheel-work, so that the main spindle can be made to run fast or slow at pleasure, as will be hereinafter described.
'lo enable others skilled in the art to make and use my invention, I will describe itsconstruction and operation.
In the accompanying drawings I have represented my invention applied to a fan shaft which isl rotated by a spring, A, acting upon a train of wheel work, t b c (l e, which parts are all inclosed within a box, B, in such manner that they can be readily got at when it is necessery to clean or to oil them. This train of wheels may be operated by a spring or by a weight in the manner of an ordinary clock; but I prefer to use springs, as above stated, when the machine is portable, but when the machine is fixed in some established place the weights and cords may be used as a motive power. The box B is intended to have some convenient contrivance applied to it by which the machine can be readily secured to a bed- Astead or other article of furniture and removed therefrom at pleasure. In hospitals the box B may be screwed to the partition over or alongside of the bed, so that the patient lying in bed will receive the benet of the fan.
The main spindle C carries on its upper end a fan, D, which may be made of a stili' sheet of metal, of thin wooden boards, or of bows covered with light paper or muslin and ornamented to suit the taste. This spindle C has affixed to italarge balance. or liy wheel,E, to
which I apply a spring-brake, that is con structed and operated as follows: F represents a spring which is arranged in a tangential position to the circumference of the iiy-wheel E, and secured at one end to the top of the fanbox, so that the opposite end, or that which is nearest to the circumference of said wheel, shall be allowed to have a free play. This latter end of the spring F receives a friction-wheel, g, which is allowed to rotate freely in a plane parallel to the top of the box B, and this wheel Inay have its periphery covered with indiavrubber or some other soft substance. 7L is a fixed standard, which projects up from the fan-box top, and has a horizontal thumb-screw, p, tapped through it, the end of which touches the spring F. By setting this screw up, the spring F, withits wheel g, will be moved toward the circumference of the Iiy-wheel E, and the friction-wheel can thus be made to act upon the fly-wheel with greater or less pressure, according to circumstances. When the screw p is set back, the spring F will recede from the wheel E and allow this wheel to receive the full force of the motive power; but if it is desired to stop the motion of the fan-shaft the screw is set up so as to force the friction-wheel p very tight against its surface.
By my improved brake the motion of the fan can be regulated at pleasure or stopped, and a patient can without any difficulty oper ate the machine when arranged within his reach.
The advantage of the use of a brake, besides that just stated, is, that the motion of the fan can be regula-ted according to the varying force of the spring A, so that a gentle breeze can be obtained when the spring is fully wound up, and also when it has nearly expended itsforce. Vith such a brake the fan can be made to work a much longer time with a comparatively short spring, and hence a small machine can be made to run uniformly for many hours at one winding up.
My improvement can be used in motive power which is adapted for operating light machinerysuch as churns and washing-Inachines--by removing the fan and applying a crank or a belt wheel in its stead.
Having thus described my invention, what I claim es new, and desire to secure by Letters baleneewheel, E, and fan D, substantially as Patent, isdescribed.
l. The application of a fretiolrbrnke to a Witness my hand in the matter of my apbalimeewheel, which is keyed to a spindle replication for a patent for a fan-power.
ceiving its motion from a train of Wheel-Work, VVM. E. WILGOX. substantially as and for the purposes described. Witnesses 2. The combination of a spring, F, frietiou- R. T. CAMPBELL,
wheel g, and an adjusting-screw, p, with a E. SGHAFER.
