Description
l UNITED STATES PATENT trice.N
DAVID RAMLER, OF UNION DEPOSIT, PENNSYLVANIA.
IMPROVED AUTOMATIC FAN.
Specification forming part of Letters Patent No. 104,768, dated June '2 J, 1870.
To all whom it r11/ay concern:
Be it known thatI, DAVID RAMLER, of Union Deposit, in the county of Dauphinv and State of Pennsylvania, have invented an Improved- Automatic Fan and Fly-Driver; and I do hereby declare that the following is' a full and eX-` act description thereof, reference being had to the accompanying drawings, making part of this specification.-
Figure 1 being a side view of the machine', Fig. 2,-a horizontal section in a plane indicated by the line x so, Fig. l.
Like letters designate corresponding parts in both figures. v
The nat-ure of my invention consists in the improved construction and arrangement for adjusting the height and angle of the arms to which the fans are attached.
Let A represent the case in which the fan` driving movement is mounted, and B the movement for giving motion to the fan, by means of spring or other power. From this Aclock-work, having a continuous motion, a
rotary reciprocating motion is communicated to an upright fan-shaft, C, by the following device: A crank-wheel or crank, a, caused to revolve at the proper speed by the clock-work movement below, is connected, by means of a rod, b, with a rack, c, which gears into a pinion, d, on the fan-shaft C, as shown in Fig. 2.
The rack c is mounted in bearings ff, so that `it can slide endwise' therein, and the revolving motion of the crank-wheel a communicates to thisrack a reciprocating motion `for- Ward and backward, and consequently it imparts a rotary reciprocating motion to the fanshaft. A balance-spring, g, secured at its outer end to a Xed bar, h, and at its inner end to the `fan-shaft,` gives elasticity, uniformity, and
gentleness to the motion of the shaft. A movable stop, p, serves for starting and stopping the fan. The fans D D are secured to projecting arms E E, which are pivoted at i t' to a sleeve, G, secured on the shaft C at the desired height. A sleeve, H, also is secured upon the shaft C, above the sleeve G, being vadjustable at different heights on the shaft, -and fastened in any desired position by Va setscrew, Z, or its equivalent. To this latter sleeve a set of connectingrods or braces, I I, is pivoted, and also to the fan-arms E E at m m. By this arrangement and construction of parts, when. the sleeve H israised, the fanarms E E are raised and drawn inward nearer to the shaft O, and vice versa, so that the `height and angular position of the fan-arms are adjusted at pleasure.
WhatI claim as my invention is- The combination and arrangement of the fan-arms E E, sleeve G, adjustable sleeve H, connecting-rods I I, and shaft C, with devices for giving motion t0 .the same, substantially as herein described, and for the purpose specilied.
Specification signed this 16th day of April, 1870. l
