GEORGE W. ZEIGLER, OF TIFFIN, OHIO.

AUTOMATIC FAN.

Specification of Letters Patent No. 23,739', dated April 19, 1859*.

To all whom it may concern:

Be it known that I, G. W. ZEIGLER, of Tiflin, in the county of Seneca and State of Ohio, have invented a new and useful Improvement in Automatic Fans for Bedsteads; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure l is an end view of bedstead showing my improvement and its mechanism. Fig. 2 is a side view of the same. Fig. 3 is a view of the escapement wheel.

The nature of my invention consists in the arrangement of certain levers on which the bedposts rest in combination with an escapement wheel, with which they are connected by a cord wound around the shaft of the wheel, the said wheel having an arm connected by a rod, with a pendulum rod, and ball, attached to the head of the bed, and to which is suspended the swinging frame or brush, the weight of the occupant of bed acting on the levers causes the cord to unwind, and turns the wheel, the flanges of which coming in contact with the arm, causes vthe pendulum rod, with which it is connected by a rod, to vibrate, and thus the brush swings over the bed, it also has a weight attached to each end, which assists its motion.

In the drawing a represents the bedstead, B the levers on which the bedposts rest at the sockets 9 and connected at letter n with the lever B which rests on the socket 9 at Fig. 2, and to which is attached at 8 the cord wound around the shaft of escapemeiit wheel F, having an arm E connected by rod D with the pendulum rod c having its bearing on the bedstead at g, the frame of the brush lo being connected with the pendulum rod c at I-I.

g-g are the weights attached to each end of the brush, and I is the connection of the wheel with the bed, and 4 is ball on the end of pendulum rod.

rlhe weight of the occupant of the bed acting on the levers B causes the cord 8 to unwind from the shaft of the wheell F and turns the wheel thus bringing the flanges of the wheel in contact with the roller of the arm E as shown at 7 in Fig. 3 and causing it to move to and fro and from its connection by rod D with pendulum rod c also causes it to vibrate thus putting in motion the swinging brush lc, the weights g g to the end which also assisting in keeping it in motion.

The mode of operation is as follows: The cord m being wound around the shaft of wheel F, by a small key, it is not put in motion until the bed is occupied, when the weight of the occupant causes the levers to descend, and'acting on the -lever B by its connection at fn, presses it down, and drawing upon the cord m unwinds it, and turns the wheel F, and the roller of lever E passing between the flanges of the escapement wheel, puts it in mot-ion, and vibrates the pendulum by means of its connection by rod D, thus swinging the fan or brush over the bed as it is attached to pendulum at H, the weights g-g assist in keeping it in motion.

Having thus described the construction and operation of my improvement I claim- The combination of the levers B B supporting the bedstead, with the escapement wheel F lever E, pendulum and fan, together with the parts connecting the same, for operating the fan from the weight of the occupant of the bed as described.

GEORGE WV. ZEIGLER.
