FAN FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 402,948, dated May 7, 1889.

Application filed Sept mber 24, 1888. Serial No. 286,228. lModel.)

To all whom it may concern:

Be it known that we, GEORGE R. LEIBER- SPERGER and GEORGE W. BAILEY, of Saegerstown, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Fans for Rocking- Ohairs; and We do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in fans for rocking-chairs; and it consists in, first, the combination, with a rocking-chair, of a rod which supports a platform or table, ashaft which has a weight secured to one side thereof at or near its lower end, and a revolving disk secured to its upper end, an adjustable support, a shaft having a fan attached to its outer end, and a friction-wheel attached to its inner one; second, the arrangement and combination of parts, all of which will be more fully described hereinafter.

The object of our invention is to provide a fan which can be attached to a rocking-chair and adjusted into any desired relation thereto, and which is made to operate as the chair is rocked byaswinging movement of aweight which is attached to one side of the shaft.

Figure 1 is a perspective of a fan which embodies our invention complete. Fig. 2 is a detail view of the same.

A represents an ordinary rocking-chair, and B an inclosing box, frame, or chamber, which is secured to one side of the chair by means of the supporting-pieces O, which are clamped or secured to two of the legs of the chair by means of any suitable devices. The ends of these two pieces C pass each other and are secured together by means of a set screw, D, thus adapting the pieces 0 to be made extensive, so that they can be applied to difierent chairs. The box B is secured to the pieces G by suitable fastenings, G, as shown in Fig. 2, so that its bottom does not come in contact with the floor. Rising from the top of this box, which is provided with a lid, H, so as to give access to its interior, is a telescopic supporting-rod, I, having the table or platform J secured to its upper end. This rod I is made telescopic, so that the plat form J can be adjusted in relation to the chair at the will of'the operator. The upper end of the rod is secured to one side of the platform, and its opposite side is braced in position by means of the rods or braces L. From the top of the box B also extends asuitable brace, N, which has one end to bear against the side of the rod 1, as shown, so as to support and brace the parts together.

The bottom of the box B forms a support for the lower end of the shaft O,Which is also made telescopic near its upper end, and which also has secured to its upper end the horizontal revolving disk P, which is supported just above the table or platform J. Secured to one side of the rod 0, near its lower end, is a weight, Q, which, as the chair is rocked back and forth, swings around in a circle and causes the shaft 0 to revolve. After the weight has once been caused by the motion of the chair to swing entirely around, the centrifugal force will keep the rod in constant motion as the chair is rocked, and the rapidity of this motion can be increased or decreased, according to the rapidity with which the chair is rocked.

Pivoted upon the upper end of the shaft 0, and supported in a horizontal position by the table or platform J, is the adjustable support R, upon which are placed the adjustable bearings S T for the fan-shaft U. This support B, being pivoted upon the end of the shaft 0, can be freely moved around through a portion of a circle, and is held in any desired position by means of the notched flange V, which is formed upon the table or platform, and with which the support R engages. By thus giving the support a horizontal adjustment the fan W can be adjusted back and forth in relation to the chair at the will of the operator. The shaft 0 being made telescopic, the disk can also be raised at the same time that the table or platform J is adjusted, and thus adjust the fan vertically in relation to the person sitting in the chair.

Through the support T is made a slot, X,

and through this slot X the inner end of the fan-shaft U passes, and to the inner end of this fan-shaft is secured the friction-wheel Y. In order to keep this frictional wheel Y always in contact with the disk P, a spiral spring, Z, is attached both to the shaft and to the lower part of the support, and this spring exerts its tension in drawing the inner end of the fan-shaft U downward in the slot X, so that the wheel Y will always bear with suflicient force against the revolving disk to cause the shaft U to revolve with the disk P.

The support R has its edges turned over so as to form guides, and the two supports S T are formed by turning up the two ends of the plate E, which has its edges to project slightly beyond the edges of the supports S I T and thus catch in the guides formed upon the support R.

Aperson sitting in the chair has only to rock back and forth, and as the shaft 0 is inclined first in one direction and then in the other the weight Q follows the motion of the shaft 0 from its own gravity, and that movement of the chair is sufficiently great to give the weight sufficient momentum to at once swing entirely around. Then the continued rocking of the chair will cause the weight to continue swinging around in a circle and thus operate the shaft.

Having thus described our invention, we claim 1. The combination, with a rocking-chair, of a supporting-rod having a table or plat-- form secured to its upper end, a shaft having a weight secured to one side and having a friction-disk secured to its upper end, suit able supports, a shaft journaled in the supports, a fan secured to the outer end of the shaft, and a wheel secured to the inner end of the shaft and operating in connection with the disk, substantially as shown.

2. The combination, with a rocking-chair, of a vertical shaft connected thereto,aweight secured to one side of the rod, a fan, and an intermediate mechanism, substantially as described, between the shaft and the fan,whereby as the chair is rocked the shaft is automatically made to revolve for the purpose of operating the fan, substantially as set forth.

In testimony whereof we aflix. our signatures in presence of two witnesses.
