CHAIR ATTACHMENT.

Specification of Letters Patent. I Patented Sept, 30, 1919.

Application filed February 6, 1919. ,Serial 1 \To. 275,355.

To all whom it may concern Be it. known that I, CHARLES E. KANODE, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Chair Attachments; and I 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 appertains to make and use the same.

This invention relates to chair attachments and the primary object of the invention is to ,provide an improved .means for changing an ordinary chair into a rocking chair.

Another object of the invention is the provision of a pair of detachable rockers, which are adapted to be secured to the terminals of the legs of an ordinary chair, so as to readily convert the same into a rocking chair.

Another object of the invention is to provide an improved means for detachably connecting the rockers to the legs of a chair, so as to hold the rockers against movement with relation to the chair legs, when the rockers are in operative position and to provide means whereby the rockers may be readily attached or detached when so desired.

A further object of the ivention is to provide an improved means carried by the rockers for forcing the chair forward, when the same has been swung backward, so as to facilitate the rocking motion of the chair.

A still further object of the invention is to provide an improved device of the above character, which is durable and eflicient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a reasonable cost.

lVith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings forming a part thereof, in which:

Figure 1 is a side elevation of the rocker showing the same applied to a chair.

Fig. 2 is a longitudinal vertical section through the same.

Fig. 3 is a transverse section on the line 33 of Fig. 2.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved rocker adapted ,to be applied to the legs 2 .of an ordinary .or any preferred type of chair 3. The rockers 1 of course are constructed in pairs and each include an arcuate body a having studs 5 andb formed on their upper surface adjacent to the ends thereof. Each of the studs 5 and 6 include spaced plates 7 and 8 for receiving the lower ends of the legs of the chair and each of the plates 7 has a threaded aperture 9 in which is fitted a thumb screw 10, the inner end of which is swivelly connected to a plate 11. l/VhBI .the ends of the chair legs 2 arepositioned in the sockets in the plates 7 and 8, the screws 10 are adjusted, so that the plates 11 may be brought into tight engagement with the chair legs, so as to firmly clamp the same between the plates and the wall 8 so as to prevent displacement and relative movement between the rockers and the chair legs.

Thus it can be seen that an improved attachment is provided for ordinary chairs, whereby the same can be readily converted into a rocking chair and thus derive further benefits therefrom.

To facilitate rocking movement of the chair, and to ush the same forward after it has been roc ed rearwardly, a plate 12 is hingedly connected at its inner end to the lower surface of the rockers adjacent to the rear ends thereof. The inner ends of the plates are positioned directly below the ends of the rear legs of the chair. The lower surfaces of the rockers are provided with a longitudinal groove 13 adjacent to the rear ends thereof,'whioh is adapted to receive the plate 12 when the chair is rocked rearwardly. The forward upper edge of the plate is provided with transverse apertured studs 15 which receive the pivot pins 16 which have the terminals thereof extended through the side walls of the groove 13 to pivotally hold the plates in position. The plate is normally held in its lowered position in engagement with the floor by means of an expansion coil spring 17 which has its lower end secured to the upper edge of the plate by means of rivets or the-like and its upper edge secured in the groove 13 by means of suitable fastening elements. This spring is of sufiicient strength, so that when the chair is given a rearward push by the legs of the user, the spring 17 when compressed will push the chair forward and thereby In practice, I have found that the form of my invention illustrated in the accom panying drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize, that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention as set forth.

v lVhat I claim as new is: I

1, In a device of the class described, a rocking chair including a pair of rockers, a hinged plate carried by the lower surface of each rocker adjacent to the rear ends thereof, and expansion coil springs arranged between the rocker-sand the free rear ends 7 of the plates, as and for the purpose specified.

2. In a device of the class described, a rocking chair including a pair of rockers having the lower surface thereof adjacent to the rear end provided with a groove, a plate, means pivotally' connecting the forward edge of the plate to the rocker adjacent to the forward end of the groove, and an expansion coil spring arranged between the rear free end of the: plate and the rocker,

as and for the purpose specified.

In testimony whereof 1, CHARLES Envnv KANODE, afliX my signature in presence of two witnesses.

CHARLES ERVIN KANODE.
