ROCKING-CHAIR ATTACHMENT;

Specification of Letters Patent.

Patented Dec. 27, 1921.

Original application filed March 9, 1921, Serial No. 451,001. Divided and this application filed August 16,

1921. Serial No. 492,832.

T 0 all whom it may concern:

Be it known that I, ANTON ZUBRYD, a citizen of Ukraine, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Rocking-Chair Attachments, of which the following is a specification.

This invention relates to certain new and useful improvements in rocking chair attachments and has particular reference to a device carried by a rocking chair and associated with a music box on the rocking chair to operate the music box during the rocking motion of the chair.

This invention further includes improve ments in the art over my copending applica tion Serial No. 451,001., filed March 9, 1921, for musical rocking chairs and embodies a floor engaging lever carried by a chair rocker and having a tensioned pitman rod connected thereto for normally holding the lever in engagement with the floor with the pitman operating a crank shaft for transmitting rotary motion to a music box carried by the chair bottom.

With the above general objects in vlew and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a rocking chair and attachment therefor constructed in accordance with the present invention showing the floor lever pivoted to the chair rocker and operating the music box carried by the chair seat,

Fig. 2 is a front elevational view of the rocking chair and attachment and illustrating the connection between the crank shaft and the music box.

Fig. 3 is a horizontal sectional view taken on line III- III of Fig. 1 showing the coil s rings connecting the pitman rod to thecliair rocker, I i

Fig. 4 is a horizontal sectional view taken on line IV--IV of Fig. 1 showing the crank shaft journaled in the side brace bars of the chair body, and

Fig. 5 is a detail sectional view taken on lino V V of Fig. 1 showing the pivotal connection between the floor lever and the chair rocker.

Referring. more in detail to the accompanying drawing there is illustrated a rocking chair carrying a music box with mechanism carried by the chair and adapted to be operated during the rocking motion of the chair to operate the music box, the chair embodying back and front bars 1 connected by a seat 2, side brace bars 3 and rockers 1, the structure elements of the rocking chair being of any well known type.

A. floor lever 5 is pivotally mounted at one of its ends upon the laterally projecting pin 6 carried by the inner face of one of the rockers 4 and carries a roller 7 at the free end thereof. A transverse shaft 8 provided with a crank portion 9 is j'ournaled in collar bearings 10 supported in the brace bars 8, while a pitman rod 11 having one end journaled to the crank 9 has the other end pivoted to the free floor engaging end of the floor lever 5.

As shown more clearly in Figs. 1 and 2 a music box 12 is secured to the bottom side of the chair seat 2 and has an operating shaft 13 projecting from one end thereof and provided with a pulley 14. The large pulley 15 is fixed to the crank shaft 8 in line with the pulley 14: and has a plate connection 16 therewith.

In order to maintain permanent engagement of the floor lever 5 as shown in Fig. 1 a pair of coil springs. 17 and 18 connected to the front and rear sides of the pitman rod 11 as at 17 and 18 respectively have the lower ends thereof attached as at 19 and 20 to the upper face of the adjacent rocker 4.

In the operation of the device rocking motion of the chair in a forward direction will cause an elevation of the crank portion 9 of the crank shaft 8 against the tension of the springs 17' and 18, the crank portion being elevated a sufiicient distance to pass over the dead center of rotation and then be influenced by the spring 17 to be pulled downwardly when the chair is rocked rearwardly while the spring 18 tends to move the crank portion forwardly to pass the dead center at the lower side of the pulley 15, rotary motion of the crank shaft 8 being communicated to the music box 12 by the pulley connection 16 as clearly illustrated in Figs. 1 and 2. The springs 17 and 18 understood that minor changes may bemade therein witheut departing from the spirit and scope thereof as claimed.

What is claimed as new is: i

In a rocking chair of the type described, a music box carried by the underneath portion of the chair seat, a shaft projecting outwardly of the music box and transversely of the chair body, a pulley upon the end of the shaft, a floor engaging lever pivoted to an inwardly projecting pin upon one of the chair rockers, a crank shaft journaled transversely of the chair, a pitman rod extending between the free end of the floor engaging lever and the crank portion of the shaft, a pulley Wheel upon the crank shaft and immediately below the pulley Wheel of the music box shaft, driving means between the tWo pulleys and springs connected to the pitnian rod and chair rocker at opposite sides of the pitman rod for maintaining engagement between the lever and the floor.

In testimony whereof I affix my signature.

ANTONZUBRYD.
