5 Claims.

YOur invention relates to improvements in chairs or .seats...for. use in passenger Ybusses or coaches and other places wherein-a tubular seat support is provided withv upwardly extending back supports which. operate. in conjunction with a connecting or top rail andwith securingmeans, for detachably holding, a seateback effectively locked in position with 'a minimum number of bolts, screws or other securing devices. I

The primary object of our invention is to provide .a new and improved article of manufacture comprising a seat or chair, the parts of which may be easily and quickly assembled or separated for replacement, :repair on other purposes.

Another object is to provide anew and improve-d chair construction in which a minimum number of .bolts and screws are required for securing the several partstogether.

A further object is to provide a new and improved chair construction in which no bolts or other securing devices project beyond the confines or contour of the seat or chair.

A still further object is to provide a new and improved construction of the character set forth in which the several parts may be easily and quickly interchanged or replaced.

We accomplish these and other objects by means of the improved construction and combination of parts disclosed in the drawings forming a part of the present application, and in which- Fig. 1 is a broken front elevation, partly in section, disclosing our improved construction;

Fig. 2 is an end elevation thereof; and

Fig. 3 is a broken detailed view, partly in section, disclosing several of the connecting parts separated from each other.

Referring to the drawings:

The numeral I is used to designate a seat support, from which the seat has been removed, having upwardly extending back supports 2 at each end of the back thereof, said supports 2 being preferably of tubular construction. Suitable apertured lugs 3 are provided near the base or lower portions of said back supports 2.

A tubular connecting rail 4 is provided with downwardly turned ends 5 each arranged to match with the upper ends of the back supports 2, as disclosed in Fig. l of the drawings. Each end 5 is provided with a suitable Centrally apertured plug or closure 6 which may be welded,

pinned or otherwise secured permanently within .Y

the end 5 to close the same, while a suitable bolt 'I is also secured Within each apertured plug E so as to extend axially from each end 5 of said connecting rail 4.

. A suitable sleeve 8 on each end 5 is provided With a central partition 9 in turn centrally apertured as at I0 to receive the bolt "I in a manner and for a purpose hereinafter more fully set forth. Each sleeve 8 is also provided with'an inwardly extending pintle I I from which is suspende-d from its upper portion a back I2, as disclosed in Fig'. 1 of the drawings.

In operation, the several parts are easily and rigidly connected by rst moving the pintles I I of 10 the sleeves 8 into the thimbled holes I4 in the upperportionsof the ends of the' backl 2. The downwardly turned ends 5 of the connecting rail, 4, are next inserted into the upper ends of the sleeves 8 with the bolts 'I engaging the central apertures 15 I in the partitions 9 of said sleeves 8. A thimble I6 is provided for each bolt l and rigidly held against the partition 9 by means of a suitable nut I l' which also holds said partition 9 and sleeve 8 tightly against the end 5 of the connecting rail 20 4. The outer diameter of the thimble I6 is less than the inner diameter of the sleeve S so that an annular socket is provided by said thimble I6 and sleeve 8 to effectively engage the upper end of the tubular back support 2 of the seat support I. 25

With the connecting rail, 4, sleeves 8, pintles I and back I2 thus rigidly connected, the assembly is placed with the back i2 between the back supports 2 and the lower ends of the sleeves 8 are placed upon the upper ends of the back supports 30 2 and moved downwardly until the upper ends of said back supports 2 are rmly seated within the annular socket or channel between the thimble i6 and the sleeve 8. As the back portion l2 Y is now between the back supports 2 and is sus- 35 pended from the pintles II, the lower portion of said back I2 may easily be moved into proper alignment or relative position with the lower portions of said back supports 2 and may then be effectively and rigidly connected and secured in position by means of any suitable securing devices, such, for instance, as the lag screws I8 passing through the apertured lugs 3 which may be welded or otherwise permanently secured to the lower portions of said back' supports 2. 45

As the back I2 is thus secured against movement relatively to the back supports 2, which are integral with the seat support I, it is obvious that the sleeves 8 and the connecting rail 5 are also elfectively held rigidly in place as said sleeves 8 50 and rail 4 are secured to the back I2 which, in turn, is rigidly secured to the back supports 2.

By means of this improved construction it is possible to easily connect various and different nishes or types of parts, such as enameled or io Y l of saidV rail; a back pivotally suspended from said painted hack supports 2 andV chromium or plated f; top or conncting'rails 4, and to assemble or separate, for replacement, repairs or other purposes,

the several parts of the construction.V
