ROCKING-CHAIR ATTACHMENT.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed January 11, 1913. Serial No. 741,416.

To all whom it may concern:

Be it known that I, GEORGE F. GIAssoN, a citizen of the United States, residing at lVyandotte, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Rocking-Chair Attachments, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to rocking chair attachments and has for its object a foot-rest that works back and forth upon a pair of wheels as the chair rocks. This foot rest may be used to support a baby chair upon which the baby may be rocked by the use of the foot to slightly lift and drop the rear of the chair. Or, the foot rest may be used in connection with a babys cab to work the baby cab back and forth as the foot rest travels back and forth upon its wheels.

In the drawings: Figure 1, is a vertical section of the chair and attachment. Fig. 2, is a front elevation of the chair with the attachment removed. Fig. 3, is a section of the attachment with a baby chair located thereon. Fig. 4, is a section of the attachment showing the use of a baby carriage in connection therewith. Fig. 5, is a detail of the telescopic rods. Fig. 6, is a detail of the eccentric catch by which the telescopic rods may be located in any desired position with respect to the chair.

A. represents an ordinary rocking chair that has on its bottom, attached by screws or otherwise, a pair of Z-bars l, the adjacent ends of which are slightly spaced so that the Z-bars, as shown in Fig. 2, form a track in which another member may travel. In the drawings, 1 have shown two of these tracks, although one track would accomplish the purpose for which the same is intended, namely to support the telescope rods 2 which support the foot board 3. This foot board is supported by a bracket 4 upon a pair of wheels 5 that have rubber tires 6, so that they will run noiselessly across the floor.

The telescope rod 2 is shown in detail in Fig. 5 and comprises a tubular portion 2 and a solid portion 2 that fits into the tubular portion and it may be adjusted at any given position by the winged set-screw 7. The free end of the solid rod 2 is flattened out and engages with a flattened lug 8 which is fastened to the foot board 3. The lug 8 has a screw 9 upon which runs a winged nut 10 so that by tightening the winged nut 10 against the flattened portion of the solid rod 2 the two members 2" and 8 may be held from relative movement and hence the inclination of the foot board 3 may be adjusted. The top of the tubular portion 2 is forked as at 2 and between these forked portions the runner 11 engages and is held in pivotal relation with respect to the forked portions 2 by the pin 12. The pin 12 also carries an eccentric forked member 13 which I am going to call an eccentric catch.

It will be seen from Fig. 6 that this is merely a lever pivoted on the pin 12 and that the enlarged portion is set eccentrically with respect to the pin 12 and is circular in contour, hence by turning the arm from the position shown in the dotted lines in Fig. (3 to the position shown in the full lines, the runner 11 is changed from a condition of freedom with respect to the track 1 to one of bondage by reason of the clamping arm engaging with the track. l/Vhen the telescoping rod 2 is slid along the chair so that the desired position of the foot rest 3 with respect to the chair is obtained, the clamp may be turned down and this position thereby maintained.

Referring to Fig. 1, the full lines show the attachment in distended position, the dotted lines show the attachment in position of non-usage. A pair of cross bars 14 that connect the rockers of the chair are separated by a distance so that the wheel may be set upon the two cross bars in the way shown in this figure; of course other forms of rests for the wheel might be provided at the forward part of the chair without departing from the general design of my invention and I do not wish to be understood as limiting myself to cross bars alone as the only possible representative of the element in my combination that performs the function of supporting the wheels when the foot rest is stowed away. Before this position is attained, however, the telescoping rods 2 are slid along the track members and the runner 11 is at the extreme back of the chair where it may be secured from movement by turning the clamping arm 13 downward. In this position the attachment is entirely out of the way and the rocker may be used in the normal way. As already stated, the length of the rods 2 may be adjusted by the means of the winged setscrew 7 and the inclination of the foot rest by the winged nut 10. In this connection a childs chair may be used. I have adapted a. childs chair for being supported by the foot rest and to this end I employ a chair which has a supporting bar 15 which is fastened to the bottom of the chair seat and which fits over the end of the foot rest by a U-bend of the bar. These bars, only one of which appears in the drawing, are fastened to the front of the seat. At the rear of the seat are fastened spring bars 16 which rest upon the posts 17 that project upward from the rear of the foot rest. This spring bar 16 has a considerable capacity of yield ing so that the foot of him who is resting in the chair may be inserted under the childs chair l8 and the chair may be slightly tilted by the movement of the foot up and down so that the child may be given the requisite motion to appease it. And, further in this connect-ion, a baby carriage may be used if desired. Such a vehicle is shown in Fig. at and is of the'conventional type with four wheels, indicated in the drawings (Fig. 4) as 19. A forked draw-bar 20 may be dropped over the shafts of the foot rest and the baby carriage and it is, of course, obvious that as the foot rest attachment moves back and forth that the rocking of the main chair will pull and push the baby carriage and give the-necessary movement to the carriage to lull the baby.

What I claim is The combination with a rocking chair provided with a track on the under side of its bottom, extending from front toback and provided with a pair of cross bars eX- tending from rocker to rocker at the front of the chair, of a foot rest comprising a runner slidable in said track member, means for holding it in any, position along the track, a pair of straight telescopingrods, one pivoted to the said runner, a foot board pivoted to the other telescoping rod at the opposite end, a wheel for supporting said foot board, and means for adjustably fixing the telescoping rods with respect to each other, whereby in stowing the foot rest away, the runner may be loosened from its locked engagement with the track and slid to the extreme back of the chair, the rods may be telescoped together. and the foot Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
