TO ALL WHOM IT MAY CONGERN:

Be it known that I, THOMAS Kenn, ot' York, in the county of York, State of-Pennsylvania, have invented a new Fanning Rocking Arm-Chair; and I do herebyr declare that thefollowing is a full and exact description thereof, reference being had to the accompanying drawings, end to the letters of referencemarkd thereon.

` The nature of my invention ,consists in attaching a revolving fan, with a transverse rotary motion, to ordinary rocking-chairs, by which a current of air is produced without any other power than that used by the occupant of the chair while rocking himself.

-To enable othersl skilled in the art tomake and use my invention,` I will proceed to describe its construction and operation.

Figure 1, in the accompanying drawings, represents the chair with the entire machinery attached, except the fan, which is represented in iig. 3.

Figure 2 represents a side view of the chair with my invention attached, except the fan as represented in iig. 3.

Figure 3 represents the fan and pulley, to which the band or strap is attached, to communicate motion to the fan. A v Y i I I I I, in g. 1, represent the rockers of the chair, resting on a platformconsisting of four piecesframed together, about one inch in thickness, and from three to four inches broad, and represented in fig.`1 by A A AA.

n n n n, in iig. 1, represent short pins, inserted in the sides of platform A A A A, projecting above said platform from a quarter to half an inch, which pins, when the chair is in motion, are received into correspouding 'holes in the rockers ofthe chair, and thus kept firmly en the platform.

O O,- in iig. 1, represent an upright board or plank, firmly attached to platform A Al A A, L L representing a stripattached to the platform, in order to throw O O further from the side of the chair.

B B, in fig. 1, represent a lever, with a cross-piece marked C G, and attached to the upright, O O, by a pivot, M. n

4H H, in fig. 1, represent two straps, attached to the Vright-hand rocker at I I, and fastened to the lever B B at C.

F'F, in iig. 1, represent a strap, fastened to the extreme ends ofthe cross-piece C C, and wrapped around the pulley E E, in g. I, represent the posts on which the fan and pulley rest.

P P P P, in fig. I, represent the back, arms, and seat of the chair.

Fig. 3 represents the fan, and a front view of the pulley.

C C, the shaft to which the several fans are attached.

l) D, the posts ou which .the fan rests.

The occupant ofthe chair, by rocking himself, imparts the motion to 'the fan. It requires very little additional power to that necessary to enjoy that luxury when this invention is not attached. i

The straps H H are alternately drawn forward and back by the rocker, to the ends of which they are attached, which imparts a corresponding motion to the lever .B B at Ci. This lever, having M as a centre or fulcrurn,'which 1s stationary, being attached to a platform by the upright, O O, has a corresponding forward and backward motion at the top, and the strapF F, being fastened to either end of the crosspiece C C, and wrapped several times around the pulley D, attached tothe shaft of the fan, imparts a transverse rotary motion to the fan.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the platform A A A A, the projecting pins n n n, the upright, O O, with lever'B B. straps II H, strap F F, pulley B, shaft C C, and fan A A, as described.
