GEORGE cgBOvnYl, or CINCINNATI, oIIIo.
`Letters Patent No. 113,620, dated April 11, 1871.
IMPRovrgMEl-ur IN A'uToMATic FANS.
The Schedule referred to in these Letters Patent and maldng part of the same.
I, GEORGE O. Bo'vnY, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Automatic Fan, of which the following is a specification.
.Ndtew'c mul Objects of the Invention. This invention relates to an improved form of selfacting fan, for attachment to a bedstead or to the'v ceiling of an apartment, or other convenient object.
General. Descrtpt'ion with Reffnencetok the Drawing.
Figure 1 is a side elevation of a bedstead to whose head-board afan embodying my invention' is attached. i
Figure 2 is atop view of the head-board and fan, showing the lateral adj ustability of the latter.
Figure 3 is a vertical section, showing the adjnsta-V I ble-bracket and the propelling mechanism lin position on the head-board.
Figure 4 is a representation of my brake for arresting or retarding at will the rotation of the fan.
Figure 5 represents my invention applied to the b edf Y other andsmallerweight acts to keep Vthe cord at the proper stretch and causes it to hug the d'rum.
The gearing F is so'proportioned as to rotate the uppermost spindle or s'haft G at a much greater velocity than that 4of the drum C.
The shaft G protrdes through the head-board ,and is connected 'by a gimbal or other universal joint, H,
with a shaft, I, that is journaled within the hollow` trough-like beam J of a crane or L-formed bracket, Whose vertical portion, consisting of a tube, K, is journaled in eyes L, that project from the front of the head-board.'
The outer end of the shaft I has a bevel-wheel, M, that gears with. another bevel-wheel N upon a shaft, O, that journals in the end of thebeam J, whence it depends vertically in the manner represented.
Two arms p p', projecting from the shaft O, may be provided with rollers I P,which, revolving upon a suitable plane or track, j, on thetop of the beam J, may serve to support the shaft O and its appendauts, and to reduce thefriction to a minimum.
Attached by thumb-screw Q to the shaft O, at any desired height thereon is the frame R,.which supports two or more arms S S' of my fan proper. My preferred-form for'these arms' is as represented, viz: a horizon -al portion, s, which rests in the frame R, and having a perpendicular portion, s', that terminates in another horizontal portion, s", to which are attached pendants T T, of mnslin, silk, feathers, or other suitable material.
The lperpi-zndicular portions may be tubular, as shown in'fig. 6, so as to permit of the horizontal part s of the arm turning therein so as to be set at diiierent angles, as indicated by the dotted lines.
The object of this adjustment is to cause the-pendants T to offer a greater or lesser obstruction to the air and thereby servelto regulate the speed of the fan.
The fan may be entirely stopped or its speed checked by means of la brake, U, which is operated by a cord, u, which passes down through the tubular portion K of the supporting-frame or crane.
' The crane may be swung from side, so as to permit of the bed being made, by the cords V V', as shown in iig; 2. f A
. i Claims.
I claim as my invention- 1. The combination of the rotary-fan R S T, shaft O, adj ustable-braclret J, gearing F, cord D, and weights E E', as 4and for the purposes specied.
' 2. The combination vof the adjustable-bracket J, shafts I O, and rotary-fanIt S T, substantially as set forth.
3. The combination of the brake U u with the rotary-fan It S T and its shafts I` 0, substantially as described. y
In testimony of which invention I hereunto set my hand.
GEORGE O. BOVEY.
