RUPERTv STRASSER, OF FORT VAYNE, INDIANA.
MOTOR FOR FANS.
SPECIFICATION forming part of Letters Patent No. 473,029, dated April 19, 1892.
Application tiled January 25, 1892. Serial No. 419,241. (No model.)
To all whom t may concern:
Be it known that I, RUPERT STRASSER, a citizen of the United States, residing at Fort \Vayne,in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Motors for Fans; and I do hereby declare that the following is a full', clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to improvements in motors for fans, particularly that class of motors carrying a fan-shaft and operated by a clock-train.
, The objects of my improvement are, first, to provide a motor for fans so constructed as to be conveniently operated upon a diningtable, at the bedside, or in any other desired situation; second, to provide a portable motor for Ventilating-fans which will operate continuously for several hours automatically. These objects are attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of my improved motor for fans, showing the clocktrain by which it is operated. Fig. 2 is an elevation of the front plate, showing a detailed view 0f my escape-wheel and oscillating levers. Fig. 3 is a side elevation of the same. Fig. 4. is a plan view of my invention, showing the plates A and A, the pinion F., and the stems C and D for winding the clock-train.
Similarletters refer to similar parts throughout the several views.
In Fig. l the clock-train, consisting of the driving-springs S and S', the cog-wheels B and B', working in the pinion E, which is secured to the shaft W, and the escape-wheel F, is secured between the parallel plates A and A, Fig. 4, in the usual and well-known manner.
In Fig. 2, to the front plate A is secured the brace M, sustaining the sleeve w, (seen in Fig. 3,) which incloses the revolving fan-shaft m. The oscillating lever G is hinged on the pivot g, secured to plate A. Lever G is provided with a parallel plate G', united thereto by the fixed pins a a, having revoluble rollers a.' a' thereon for the engagement of the escape-wheel F, and said lever G is joined to crank N of the fan-shaft m by the connecting-link I. The oscillating lever H is hinged on the pivot h and has a parallel plate H', Fig. 3, united thereto by the iiXed pins a a, having revoluble rollers a/'a thereon for engagement with the escape-wheel F, and is joined to the crank N by the connecting-link L. The escapewheel F is so constructed as to produce the least possible friction, the faces of each cog or tooth being straight instead of rounded, as usually made. The revoluble rollers d' a' with which the oscillating levers G and H are provided very materially diminish the friction caused by their engagement with the escape-wheel F. The oscillating lever H assists the lever G over the dead-center and produces a revolution of the fan-crank N instead of an oscillation. Every revolution of the escape-wheel F causes as many revolutions of the fan-shaft and the crank N as there are cogs or teeth in the wheel F.
In Fig. 3 is shown in section the frontplate A, the oscillating lever G, having part G' and revoluble roller a', and connected tothe crank N by link I, also oscillating lever H, having..
part II and revoluble roller a' for engagement with wheel F, which turns on shaft W. Lever H is also joined by the link L to crank N, which regulates the revolution of the fanshaft m, to which liolders may be attached in any suitable manner. To the brace M may be united or secured any suitable sleeve w, inclosing the shaft fm.
When my device is in practical operation, the amount of friction is greatly reduced land its working efficiency greatly increased by by vmy improved escape-wheel F and revoluble rollers a' a', above described. The practical efiiciency of my motors for fans is also increased by the use of the two oscillating levers G and H, which by their arrangement and construction above described at all times carry the crank N over the. dead-center and cause the fan-shaft m to revolve instead of oscillate. Y
Vhile I prefer to use my device for ventilatiiig-fans, it may be used to supply motive power to sewing-machines and pumps or for IOO the rocking of cradles and many other purposes.
I 'am aware that prior to my invention motors for Ventilating-fans operated by a clocktrain have been in use; but no portable moior for fans has ever been used, of which I am aware, in Whiehthe friction has been reduced by revoluble rollers and straight-faced escape-Wheel eogs and in which the fan-shaft' was made to revolve instead ot' oseillate by two oscillating levers connected to the fanshaft, as heretofore described. I do not, therefore, broadly claim a motor for fans; but
WhatV I do claim, and desire to secure by Letters Patent, isv RUPERT STRASSER.
