UNITED STATES PATENT OFFICE.

CHAIR ATTACHMET.

Application med une 11,

This invention contemplates the provision of a chair attachment, constructed for association with the legs of the chair for the purpose of varying the height of the chair las the occasion may require, as well asto strengthen the chair and add to the rigidity of the. legs thereof.

In carrying out the inventlon, 1t 1s my purpose to provide an attachment for the above mentioned purposes, which can be manufactured and sold at a nominal cost, and one capable of being uickly and easily assoclated with or removed rom the chair as deslred.y

The nature and advantages of the mvention will be better understood when the following detailed descriptlon is read 1n con nection with the accompanying drawings, the invention residing in the constructlontcombination and'arrangement of parts as clalmed.

In the drawings forming part'of this appllcation, like numerals of reference indicate similar parts in the several vlews, and where- Fi ure 1 is a view of the chair showing the attachment applied thereto.

Figure 2 is a fragmentary detail v1ew of the attachment art y in section.

Fi ure 3 is a agmehtary plan view of the attac ent.

Figure 4 is a sectional view of the tie rod. Referring to the drawing in detail, 10 1ndicates a chair of ordina construction and wherein 11 represents the eg with which the attachment is adapted be associated.

The attachment comprises a pa1r of crossed tie rods 12 adapted to be arranged diagonally between the legs of the chair as clearly illus-` trated in Fi re 1,.and while any suitable meansy may employed for varying the o length of the rods, I preferabl ma e use of turnbuckles indicated at 13. fheouter extremity of each rod 12 is formed to provide a relatively broad Hattened surface :14 upon4 which the .adjacent leg 1I of the chair reposes, and this portion 14y is provided with an opening 15 thru which a suitable fastening element is adapted to pass for the purpose of securing the rod -to the leg of the chair. Each of these extremities 14 1s joined to an adjustable leg extension each lincluding a v1927. serial No. 198,164.

hollow tubular member 16 provided with a foot of rubber or an .other suitable material indicated at 17. Adyjustably associated with the tubular member 16 of each extension `is a threaded portion 18 of the adjustable section 55 of the extension, this threaded portion 18 depending from the tie rod 12. This adjustable extension `also includes a portion 19 rising above the tie rod, which portion is substantially V-shaped in plan and arranged to engage the outer side of the adjacent leg as clearly illustrated in Figure 1. When the attachment is associated with a chair, the tie rod can be adjusted through the instrumentality of the turnbuckles 13, thereby draw'- 65 ing theangular shaped extension 19 into engagement with the legs of the chair to alford the latter maximum strength and rigidity. This is particularly true when the attachment is used with chairs, the legs of which I0 are lnot ri idly connected therewith, or inA other wor s, have become slightl loosened by wear or use. In addition to atl'hrding the chair this desired rigidity, making the chair perfectly safe for use, an ordinary chair may beadjusted to vary its height through the instrumentality of the adjustable leg sec tion, thereby converting an ordinary chair into a high chair for children. If desired, the tie rods 12 may be jointed to ther at `80 their point of intersection by a suitalee clamp 20. The invention in its entiret is very simple in construction and can be both maufactured and sold at a nominal cost, and quickly attached to or removed from the chair as the 35 occasion may require.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resort- .ed to when desired, as fall within the scope of what is claimed.

What I claim is:

A chair attachment of the character de- -scribed comprising a pair of tie rods adapted to be arranged diagonally between the legs 'of the chair, a turnbuckle included in the length of each rod, each rod terminating t0 100 to engage the outer surface of the adjacent leg, a threaded portion depending from the extremity to one side of said opening and in align with said extension, and an adjustable foot associated with said threaded portion.

In testimony whereof I aix my signature.

GEORGE WILLIAM LOVERIDGE.
