ROCKER ATTACHMENT.

Application filed December 3, 1915.-

' To all whom it may concern:

, Be it known that 1, James C. CURTIS, a

citizen of the United States, residing at Cisco, in the county of Placer and State of Californimrhave invented certain new anduseful Improvements. in Rocker Attachments, of which the following is a specification. v

My invention relates to chairs'and more particularly to a rocker attachment for chairs. I

The primary object of my inventionresides in the. provision of animproved rocker attachment for association with the legs of a'stationary chair, said attachmentibeing movable to convert astationary chair into a rocking chair, novel retaining means being removably associated with the legs of the chair and the attachment for maintaining the attachment in a substantially rigid Another object of my invention resides Y in the provision of a novel securing means associated with the rocker forpivotally connecting the rocker andthe legs of a chair, said rocker being movable into engagement with the under surfaces of the legs of the chair and held in this position when the retaining means is placed into engagement with the securing means. 1

A further object of my invention resides in the provision of a rocker attachment, each rocker of which is formed in two sections, novel means being associated with one of the sections for holding the rockers in-an inoperative position to permit of the use of the stationary chair in its usual manner.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction eilicient in operation and one that can be manufactured'and placed upon the marliet at a minimum cost.

Other objectsas Wellasthe nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed outin the claims forming a part of Y this specification.

In the drawings, Figure 1 is a side elevational view of my invention associated with the legs of a stationary chair to provide a rocking chair. Fig. 2 is an enlarged fragmentary side elevational view of my invention in a folded or inoperative position on have been swung into this position, l

the legs of a stationary chair. Fig. 3 is an enlarged transverse sectional view 'taken'on line 3-3 of Fig. 1 illustrating to advantage the construction'of one of the securingelements.

Referring more particularly to the drawings in which similar reference numerals designate like and corresponding parts throughout'the different views, I providea stationary chair including a seat 1 having the back 2 connected thereto through the medium of braces 3, the sides of the back eX- tending downwardly to provide rear legs l which are connected to the forward legs 5 through the medium of suitable cross bars 6Q The construction of thischair forms no es 'sential part of my invention, it being only necessary to show the same to illustrate the advantages of .my invention which, inci- 'd'entally, can be readily associated with practically any typeof stationary chair now in use. Associated with the legs i and 5 of the chair is my improved rocker attachment. .1

The attachment in this instance consists essentially of two rockers including two

sections

7 and 8 pivotally connected to each other through the medium of a hinge 9; In order to pivotally connect the sections 7 of rockers to the front and rear legs of chair, I have provided my improved connecting elements. In this instance, each of these elements is formed preferably from a single piece of flexible rod metal which is bent in termediate its ends to provide a coil 10, the arms 11 which extend therefrom being arranged in divergent relation with each other, while the outer ends of the arms are bent into parallel relation with each other and terminate in loops 12. The arms of the elements arranged on the inner sides of the legs are slightly longer than the arms of the elements on the outer sides of the legs. Two of these elements are ar anged upon the inner and outer sides of each of the legs and pivotally connected thereto through the medium of a bolt 13 which'entends through a transverse opening in the chair leg, the bolt being engaged by a nut 14, Loops 12 on-the ends of the arms are connected upon opposite sides of the sections 7 of the rockers through the medium of suitable fastening devices 15. In order to hold the rockers 7 in substantially rigid engagement with the under surfaces of the legs after the rockers have 7 provided a plurality of retainingrings 16, said rings being slidably mounted with the elements and thereby maintain the parts in a substantially rigid position.

As is'set forth, the rockers are formed of two sections 7 and 8.7 Now, in order to hold these sections in substantially rigid position when the rocking chair is in operation,

I have connected eyes 17, to each of the vsections 8 adjacent the hinges 9 which are en- 'gaged at times by hooks 18 pivotally mount- .ed on the sections 7. In order to hold the sections 8 against the rear chair legs when it is not desired to use the rocker attachment "and so prevent the sections 8 from interfering with a person walking close to the chair,

I have connected other eyes 19 adjacent the free ends of the sections 8, which eyes are engaged by the pivotally mounted hooks 20 on the rear legs 4L.

Although I have shown and described the preferred embodiment of my invention,flI desireit to be understood that I am not to be limited to the exact details shown, however, I desire that great stress be laid upon the arrangement of the improved rocker attachment movably associated with the legs of astationary chair as well as the novel retaining means associated with the securingmeans for the rockers for reinovably maintaining the rockers in substantially rigid, relation with a chair.

From'the above description taken in connection with the accompanying drawings, it can be easily seen that I have provided a'device that is simple in construction, con- -tain'ing but a few simple partsthat can be cheaply manufactured 'and assembled and When assembled can be placed upon the market and sold at a minimum cost. 7 It will be understood that the abo've de-' scription and accompanying drawings .com prehend only the general embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of'the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thusdescribed my invention,

what I claim as new and Letters Patent, is: c

1. A rocker attachment including, in' combination with the legs of a stationary chair, a pair of rockers, means connected to the legs of the chair and to the rockers whereby the rockers may be swung into either an operative or an inoperative posidesire to secure by tion with respect to the legs, and retaining the legs and about the pivotal connecting 1 means to prevent movement thereof and consequently maintain the rockers in an operative position.

2. A rocker attachment including, in combination with the legs of a stationary chair,

a pair of rockers,- means for pivotally connecting the rockers, to the legs of the chair to permit of the rockers being removably arranged in'engagement with the lower surfaces of the legs of the chair, and rings slidably mounted on the chair legs for engagement with the securing meansfor'removably holding the rockers in an operative position. 7 g a 8.
