SEAT-BACK.

To all whom it may concern:

Be it known that I, HOWARD G. Bnor'r.

-a citizenv of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Seat-Back, of which the following is a specification.

This invention relates to backs for board seats such as used in circuses, baseball parks and other places of assembly, one of the objects of the invention being to provide a back which can be readily applied to or removed from the seat without requiring the use of any separate fastening means, the entire back being formed in a single length of spring material whereby a yielding support for the back of the user is obtained.

ith the foregoing and other objects view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a perspective view of the back, the seat to which it is applied being indicated by dotted lines. Fig. 2 is an enlarged section on line A-B Fig. 1.

Referring to the figures by characters of reference 1 designates a side strip of the back, said strip being provided, at its lower end, with a forwardly extending U-shaped clip 2 occupying substantially the same plane as the strip 1. The upper end of this strip 1 merges into a cross rod 3 having a downwardly extending terminal arm t provided at its free end with a forwardly extending eye5, there being a coil (3 upon the arm 1 and above and close to the eye 5, this coil being formed by the end of the wire of which the arm 1 and the eye 5 are made. Another side strip 7 is provided and is similar to the strip 1, said side strip having, at

its lower end, a forwardly extending U- shaped clip 8 similar to the clip 2, the lower terminals of the two clips 2 and 8 being constrip 9. At its upper end the side strip 7 merges into a cross rod 10, this rod extending between the Specification of Letters Patent.

eye 5 and the coil 6 and the upper portion of the side strip 7 being seated within the eye. Thus it will be seen that the angle formed by the rod 10 and strip 7 is'held against movement relative to the arm 4 as will be apparent by referring especially to Fig. 2. That end portion of the rod 10 farthest removed from strip 7 is coiled around the upper portion of the side strip 1 and the portion of the top rod 3. This adjacent coil, which has been indicated at 11, thus serves to secure the rod 10 to the side strip 1 and, by engaging the top rod 3, serves to prevent the rod 10 from sliding upwardly or downwardly along the side strip 1.

From the foregoing it will be seen that the entire back is formed in a singlelength of material, this material being preferably in the form of a stiff spring wire of sufficient strength to properly support the back of an ordinary person.

In using the back, the clips 2 and 8 are placed in engagement with the front edge portion of the board seat C and are then pushed rearwardly onto the board until the side strips 1 and 7 are brought close to the rear edge of the board. The person using the back can then be seated on board C between the clips 2 and 8 and the upper and lower cross rods 3 and 10 will extend across the back and constitute eflicient supports.-

It will be apparent that a seat back such as herein described can be cheaply manufactured and as it is formed in but a single length of stiff Wire, there are no parts which can get out of order.

The device is moved from position on the board seat C without the use of screws, clamps or any other similar devices such as have heretofore been necessary in applying backs to seats of this type.

If desired a cushion may be combined with the seat. This cushion, which has been indicated at 12 may be of any preferred construction and is preferably formed with eyes- 13 at the back corners thereof and which slidably engage the side strips 1 and 7.

As the side strips land 7 diverge upwardly it will be seen that, should it be desired to clean the board on which the cushion l2 r'ests, it is merely necessary to swing the cushion upwardly and back- 5 wardly so as to cause it to pass between the 1 side strips 1 and 7 whereupon it Wlll hang particularly advantageous because it can be quickly placed in or reprotected from rain.

down back of the seat and thus leave the board C exposed between the clips 2 and 8. By sliding the eyes or rings 13 downwardly along the strips 1 and 7 and thence forwardly along the clips and finally downwardly onto those portions of the clips under the board C, the cushion can be held suspended under the What is claimed is 4 v A seat back including oppositely disposed U-shaped clips, a cross strip integral with the lower portion with said portions for engaging the lower surface of the structure to which the back is applied, connected side strips extending board where it will be thereof and cooperating ion and slidable along the diverging side I strips and along the upper and lower portions of the clips, said cushion being adapted to swing rearwardly between the side strips. lln testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
