IMPRCVEMENT'IN CHAIR FAN ATTACHMEANATVS.

Specification forming part of Letters Patent No. 140,047, dated June 17, 1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that I, BENJAMIN L. JORDAN, of Mcrcersburg, in the county of Franklin and State of Pennsylvania, have invented a new and useful improvement in Operating Fans or Fly-Brushes; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a prospective view of a chair having my improvement attached. Fig. 2 is a sectional side elevation of the same.

This invention relates to an arrangement of devices for operating a fan or fly-brush over a table, or in the vicinity of the head of the person using; and its objectis to operate said fan or brush by the foot of the user instead of actuating it by means of costly clock-work machinery, and also by locating the main shaft of the device behind the chair of the user, and extending the fan-shaft above his head to secure for the same a longer sweep and more extended influence than is convenient or feasible with'mechanism located upon the table or secured to the front of the users chair. It therefore consists in a treadle attachment adapted and arranged to be readily attached to or detached from any ordinary chair, said treadle being connected by suitable cranks and rods to a rock-shaft located upon the treadle attachment at the rear of the chair, and a shaft extending upon and from said rock-shaft behind the chair, and bearing at its top an arm which projects forward from said shaft above the head of a person sitting upon the said chair to any proper distance. When said treadle is actuated by the foot of a person sitting upon the chair the said arm is caused to vibrate and a bunch of paper strips or any other suitable material will be caused to flutter back and forth in front of said person and effectually keep the flies at a distance. If desired a fan may be substituted for the described fly-brush.

That others may fully understand my improvement I will particularly describe it.

A base-board, A, is prepared, of sufficient length to rest upon the front and back rungs of the chair, and extend alittle distance back of the latter. Upon each side and to the edge of the board A I secure obliquely an arm, B,

which projects downward and forward, and forms a seat for the front rung 0 in the angle between said board and arms. At the rear part of said board I make a longitudinal slot, a, and pass through said slot a screw-hook, D, which clasps the rear rung E, and holds the boa-rd A firmly attached to the chair. The slot a enables the hook D to be adjusted forward or backward as may be necessary to adapt it to chairs of various dimensions. A treadle, E, is pivoted to the lower ends of the arms B, and is located conveniently for operation by the foot of a person sitting upon the .chair. The rear end of said treadle, or an arm extending rearward therefrom, operates a bell-crank lever, F, by means of a connectingrod, Gr,and said bell-crank operates a rockshaft, H, by means of a connecting-rod, I. Said rock-shaft moves upon a vertical axis fixed to the rear end of the board A. A socket is made in the rock-shaft, and coincident with the axis thereof, to receive the end of the shaft J, and a removable clip, K, attached to the upper bar of the chair-back holds a ring, L, which serves for an upper. bearing for the support of said shaft J. I think it advisable to make the socketin rockshaft H octagonal, as the shaftJ can then be set so as to present either face to the front; but the same result may be attained by other means. A mortise is made through the upper end of the shaft J for the insertion of the end of a vibrating-arm, M, to the front end of which the brush or fan N is attached. This arm may be retained in place by a small key, so that it will be readily removable from the shaft J.

The arm M may be attached to the shaft J by any other convenient method.

The arm M may be set so as to extend in any direction from the chair of the operator, so as to operate over a sick person in bed, either at the side or even behind the chair, and the Whole may be' readily removed and packed away.

Having described my llllPlOVQlllGlllE, what I claim as new is- 1. In combination with an ordinary chair, theremovable base-board A, bearing a treadle, E, and operative mechanism to convey mo= tion from said treadle to a vibrating-arm, M,

which bears a brush or fan, substantially as set forth.

2. The combination and arrangement of the base-board A, arms B B, slot a, and screwhook D, as set forth, for convenient attachment of said board to the front and back rungs of a chair.

3. The treadle E, bell-crank F, and rockshaft H, with their connecting-rods, combined with shaft J and arm M, as and for the purpose set forth.
