tintin( ttiea niet can Letters PatentvNo. 109,744, dated November 29, 1870.
IMPROVEMENT l-N FAN.. ATTACHMENTS FORiROCKlNG-CHAIRS.
The Schedule referred to in these Letters Patent and making part of the same.
We, RUDOLPH KNAFFL, M. D., of Nashville, Davidson county, und THEoDoRE M. SoHLEIEn, of Knoxville, KnoX county/Tennessee, have invented an Improved Fan Attachment for Rocking-Chairs, of which the following is a specification.
Nature a-mlObjects of the Invention.
Our invention consists of a mode of attaching to a rocking-chair and operating a fan so that the motion of the formertransmits a reciprocating rotary movement to the latter, which may be placed a little above and in front of' the person in the chair.
-Dcscrfipt-ion of the Accompanying Drawing.-
The drawing represents a perspective View.
General Description.
. A, the rocking-chair, may bc of the usual Akind.
Our invention does not demand any peculiar construction of the chair proper.
In the illust-ration the fanattachinent is shownas connected to the chair at three points, namely, the middle, the back B, and the ends of' the rockers C C.
IVe consider this a convenient mode of 'attaching the device, but donot limit ourselves to this or any other peculiar mode.
D is a post, which, in the illustration, is shown as bifnrcated at its lower portion and tubular at the lremainder of its length. y
The feet d d ot the post are secu-red, by screws,
clamps, sockets, or otherwise, to the rear ends of the rockers C G, and the stem of the post D is secured, by the described or any sufticieut'ineans', to the back B ot' the chair.
At the upper end of the post D is a tubular branch or arm, E, which may be articulated with the post orbe permanent at a given angle.
0n the end ofthe arm E is the axis f ofthe fan F. Ihc rotary I'ecipmcation of the fau is produced by two springs, which may be of India rubber or wire coils, or they maybe formed of single leaves or bars of wood or met-al.
On the axis f ot' the fan l is a roller or drum, H, over which passes a cord, l.
One end of the cord connects with theupper spring K, which is fastened to the arm E at k ,f and the other cnd of the cord I, after traversing the tubular arm E and a portion of the tubular stem D, is united to the upperend ot' the vertical rod L, whose lower end is kept constant upon the fioor by means ofthe spring M.
I stem may be employed.
This is' a matter of detail, land we do not confine ourselves to any specific detail in this respect.
Operation.
Then the, person in the rocking-chair tilts it backward, the rod L is thrust upward in the stem D, slacking the cord I, and permitting the contraction of the upper spring K. v
The action of the latter is to draw upon the slackened cord, whose motion over the roller H rotates the i'an in one direction.v
As the chair is tilted forward the dominant spring M comes into piay and draws down the rod L, pulling on the cord I, elongating the spring K, and rotating the fan in a direction the reverse ot' the former motion, by the transit of the cord over the roller H.V
IVhen the rod L is thrust upward the spring K is allowed to act and draws the cord in one. direction. When the rod L is allowed to descend the strong spring M becomes dominant and draws the cord in the other direction, eiongating the spring K.
The elbow at the junction of the stem D and arm E may be jointedso as to adjust the height of the fan to snit the convenience ofthe person in the chair.-
We claim as our invention- The combination of the fan-operating parts, consisting of rod L, spring M, cord I, and spring K, communicating between a relatively-fixed point on the stem D Evand the door, with which the foot ot' the, rod is held in constant contact by the dominant spring M, snbstantiaily as shown and described.
