Description
NITED STATES JOHN M. BEVERLEY, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN MOSQUITO-'FANS.
Specification forming part of Letters Patent No. 117,969, dated August 15, 1871; antedated July 31, 1871.
To all whom it may concern:
Be it kl1()\Vll that I, JOHN M. BEVERLEY, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improve ment in Mosquito-Fans; and I do hereby declare the followin g to be a full, clear, and exact description thereof, which willenable others skilled in the art to which my invention appertains to make and use the same, reference being had to the ac cmnpanying drawing forming part of this specification, in which Figure 1 is aside elevation of my invention, and Fig. 2 is a detached section of the pendulum employed in operating the fan.
Similar letters of reference indicate correspondin g parts in the several figures of the drawing.
My invention relates to that class of mosquitofans which has an oscillating movement; and the improvement consists in the mechanical arrangement of the pendulum, by which the same may be adjusted to any graduated length of stroke. It consists, further, in the combination of the several parts, whereby the fan may be ad justed to any desired point, a description of which will be hereinafter more fully given.
In the accompanying drawing, A represents the frame, within which is secured a combination of geared wheels that imparts an automatic tilting movement to the pallet B through the medium of a coiled spring in the usual manner; but as the same forms no part of the present invention a description thereof in detail is not necessary to be herein particularly given. Said pallet is attached to a horizontal shaft, C, which is pro vided with asupplemental lever, D, to which is pivoted pitman E. Said pitman is also pivoted at its opposite end to the upper end of a vertical arm, F, the lower end of which is firmly affixed to a horizontal rock-shaft, G. Affixed to the lower side of said shaft is the pendulum-rod H, to which are rigidly secured arms (I d. The outer ends of said arms are slightly enlarged, and provided with apertures, within which' is secured the shaft J, which supports the fan. Said shaft is so fitted within the arms as to admit of a freeand-easy sliding movement, and is rigidly secured at any desired point by means of set-screw e passing into the end of arm (I and against the same, by which means the graduated stroke of the fan is obtained. The fan K may be con structed in any known form and of any suitable material, which is secured to the lower end of shaft J in the usual manner. I provide the pendulum-ball L with a stud, f, which is loosely fitted upon the pendulum-rod H in a manner admitting of a vertical sliding movement, and is so arranged as to be secured firmly at any desired adjusted height by a set-screw, g, affixed in the end of said stud, by which the momentum of the pendulum is increased or decreased as the ball is moved upward or downward upon the rod. Firmly affixed to the upper end of frame A is a supporting-arm, M, one end of which is loosely fitted within the upper end of a vertical standard, N. The arrangement of said arm is such as to slide through the end of said standard, an d is capable of a rocking movement therein, by which frame A may be adjusted laterally to any given point and turned to the desired angle by the rocking movement of the arm, thus bringing the fan to the required position, which is firmly secured by a set-screw, h, in the upper end of said standard that comes in contact with and against the arm. The lower end of said standard is screw-threaded, by which the same is secured to and within the base 0, upon which the entire device is supported. Should it be found necessary to suspend the fan from the ceiling above, the standard is removed from the base, inverted, and secured to the ceiling, the arrangement of arm M being such as to admit of the same.
In operating my invention the several parts are adjusted to bring the fan into the required position, an oscillating movement being given thereto, through the medium of-pitman E and supplemental lever D, by the automatic tilting movement of pallet B imparted thereto by the rotating movement of the gearing in the usual manner.
Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of pallet B, shaft C, supplemental lever l), pitman E, arm F, rockshaft Gr, pendulum-rod H, fan-shaft J, frame A, arm M, and standard N, the whole arranged to operate together, substantially in the manner and for the purpose described.
The above specification of my invention signed by me this 7th day of December, 1870.
