THEATER-CHAIR CONSTRUCTION.

Application fi-la J'u1y.13, 1916. Serial N fioasve;

To all whom it may concern: 7

. Be it known that I, RAY TRAVERS, a citizen of the United States, and resident of New London, in the county of Waupaca and State of Wisconsin, have invented new and useful Improvements in Theater-Chair Con-V structions, of which the following is adescription, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in their thinness and at their angular points of connection with the heavier standards are very liable to havefractures or other flaws due to the unequal contraction of the, parts while the molten metal .usedin casting the standards is cooling and settling in the sand. It has. been found that a large percentage of the standards are defective, many break during shipment and while attaching the backs and seats thereto and others break in use.- This breakage materially increases the cost of the unbroken standards and-provision is usually made therefor.

Many attempts have been made to overcome this breakage by forming-the standards of stamped steel but were not found com mercially practical due to the lack of rigidityof the standards and also due to the fact that the give of the steel standard would soon loosen and work the screws which fasten the standards to the floor out of the floor.

It is one of the objects of the present invention to. overcome the beforementioned objectionable features'and provide a theater chair construction which will be light in weight, strong and durable andwhich is not liable to break in shipment or in use.

A further object of the invention is to provide a theater chair construction in which the standards proper are formed of cast metal and all projectingparts are formed of Specification of Letters Patent Patented Aug. 31, 1920." j

stamped steel and fastened to the standards in a rigid manner to connect the seat and back thereto. 1 I

A furtherobject of thefinvention is to provide a theater chair construction which is of simple construction andis well adapted for the purpose-described.

the invention consists of the improved theater chair construction and its parts and combinations as set forth in the claims, and all equivalents thereof. V

In the accompanying drawing inwhich the same reference characters indicate the same parts in all of the views:

V Figure 1 is a central vertical sectional view of the Fig. 21s a horizontal sectional view there of taken approximately on line 2-2 of:

Fig. 1.

Referring to the drawingthe numeral 5 indicates a standard which is formed of cast iron and is providedwith the usual legs 6,

medial or seat portion 7, upper or arm portion 8 and rear or back portion 9. The legs 6 are provided with the lower flanges or base portions 6 for attaching the standard With the above and other objectsin View improved chair construction and to the floor by means-of screws 10, and the usual arm 11 mounted thereon.

with an angular seat bracket 12.which. has

its opposite endportions 12 secured to the standard by rivets 13 The'bracket 12 is upper-arm portion Sis adapted to have thee-5 formed of commercial band, plate or sheet 1 steel stampedto the desired form and is provided with a medial inwardly projecting seat attaching portion 14c: having a ball socket 15 provided thereinwhichforms part of the hinge connection 16 betweenfthe bracket forming part of the seat 18' The back portion 9 of the standard has attached thereto'by bolts 19 a back bracket 20 which is formed with afiat connecting portion 21, bearing against the rear edge of the standard and through which the bolts 19 pass, a rearwardly extending portion 22 and angularly extending perforated ears 23 .to which the The back bracket 20 is also formed of commercial sheet or plate metal stamped to the member 12 and the brace arm 17 j back 24 is attached-by bolts 25,. H

mar-I desired form to lit the standard and the back, and to incline the back portion to the desired angle.

The standard positioned at the end of a row of seats is provided with a single back bracket and a seat bracket on its inner side Whereas the inner standards have double back brackets'and seat brackets on opposite sides of the standards which are connected thereto in pairs by the same rivets 13.

By providing the standards with the stamped steel brackets the backs may be easily fit thereto, in the event of the standards not being in parallel alined positions, by springing the brackets or the ears thereof to accommodate and line up with the back. It isalso of'great advantage to provide standards with removable brackets whereby brackets of other forms may be used to hold backs and seats of different kinds.

While the standard has been described as formed of cast iron and stamped steel metals it is to be understood that the invention contemplates the use of any kind of cast metal and any kind of bendable commercial metal.

From the foregoing description it will be seen that the weight of the complete standard is considerably less than if entirely formed of cast metal and that the projecting protions are not liable to break in shipping nor in use, and that all of the features of advantage of the ordinary all cast metal standards are retained with the added features of the non breakability, less weight and cost and less work in fitting the parts together.

What I claim as my invention is: 1. A standard for a theater chair, comprising a cast metal standard member having leg )ortions a medial )ortion and a back oor 7 I tion, a bracket iormed of stamped sneet metal connected at its opposite end portions to the medial portion of the standard member and projecting medially outwardly therefrom, and a back bracket formed of stamped sheet metal connected to the rear edge of the back portion and projecting rearwardly therefrom and having back attaching portions which extend at an angle from said rearward portion and away from each other.

2. A standard for a theater chair, comprising a cast metal standard member having leg portions, a medial seat portion and a back portion, a seat bracket formed of stamped sheet metal connected at its opposite end portions to the medial side portion of the standwhich extend at an angle from said rear-- ward portion and away from each other.

3. A standard for a theater chair, com-'5 prising a cast metal standard member having leg portions, a medial seat portion and a back portion, a seat bracket formed of stamped sheet metal connected at its opposite end portions to the medial side portion of the standard member and having a medially outwardly projecting portion provided with a )art spherically shaped recess and a U- shaped back member formed of stamped sheet metal connected to the rear edge portion of the back portion and projecting rearwardly therefrom and having back attaching perforated ears which extend at an angle from said rearward portions and away from each other.

4. A standard for a theater chair, comprising a cast metal standard member having leg portions, a medial seat portion and a back portion, sheet metal seat brackets positioned on opposite sides of the medial portion of the standard member and connected to said member by the same securing means, said seat bracket formed of stamped metal and having medially outwardly projecting portions provided with part spherically shaped recesses, and a U-shaped back member formed of stamped sheet metal connected medially to the rear edge of the back portion of the standard member and projecting rear- Wardly therefrom and having back attaching portions which extend at angles from said rear-ward portions and away from each other forconnection with seat backs posi
