FRONT BOLSTER AND BODY-SUPPORT FOR CHILDRENS WAGONS.

Specification of Letters Patent.

Application filed y 8, 1905. Serial No. 259,286.

'its object to provide a simple and inexpensive bolster and body-support for the purpose that is light, strong, and durable and that is composed of a reduced number of parts which are readily constructed and assembled.

A further object is to provide a front-axle bolster in which the tongue-straps, tonguehounds, axle-bearings, bridge-supports, and bearing-bridge are integral and adapted to be constructed of a single piece of strap-steel.

A further object is to provide a bolster of the kind with a simple and inexpensive trusssupport for the body of the wagon having increased strength and that is braced to withstand the torsional strain of the bolster on the bearing of the support. 1

I accomplish these objects by constructing a bolster and support as hereinafter described, and illustrated in the drawings, in which Figure 1 isarear elevation of mybolster and support mounted on an axle. Fig. 2 is a bottom view ofthe same with the axle in part broken away. Fig. 3 is an end elevation of the same with an end arm of the bolster broken away; and Fig. 4 is a front elevation of the central portion of the bolster, showing portions of the arms of the bolster and of the body-support.

In the drawings, 1 is the bolster, which is constructed of a single piece of strap-steel of the required length bent to form in their order at opposite ends of the central portion 2 the forwardly projecting tongue-straps 3, the hound-braces 4, the axle-bearings 5, the bridge-supports 6, the bridges 7, and the oppositely-projecting and downwardly and outwardly curved arms 8, having end portions 9 angled parallel, each being provided with an orifice 10 to receive an axle 11. The tonguehounds 3 are also provided with orifices 12in alinement with the orifices 10 to receive the The bolster is completed by bending the edges of a bearing-plate 13 around the outer edges of the bridges 7, which is effected by a single operation of a die-press, and providing a central orifice 14 through the bearing-plate 13 and the bridges 7, one-half of the orifice being in each bridge.

The hound-braces 4 and the bridge-supports 6 are each quarter-twisted on opposite sides of the bearings 5, whereby the upper portions of the bridge-supportathe bridges, and the arms are as respects their sides in planes at right angles to the planes of the sides of the central portion 2.

The body-support 15 comprises the bearing-disk 16, having a central orifice adapted to register with the orifice 14 of bearing-plate 13 of the bolster, and a pair of complementary truss-supports l7 and 17, each formed of a single piece of strap-steel bent to form at opposite ends of a central bearing portion 18, the front arm 19 and the rear arm 20, diverging therefrom. The central bearing portions 18 of the truss-supports are riveted to the top face of the bearing-disk 16 in parallel positlon at equal distances from a line diametric of the disk and with their outer edges tangential to the disk. The front arms 19 are quarter-twisted, one to the right and the other to the left adjacent to the central bearing, to bring their inner edges outermost and the arms diverging from each other at equal angles from their respective bases. The arms 20 are angled obtusely from the bearings 18 and relative to each other are also angled edgewise to converge and cross each other at about half their lengths, and at their crossing they are secured together by a clipband 2 1. The free end portions 22 of the arms are angled to coincide with a common plane and are provided with screw-holes 23 for attachment to the bottom of a wagon-body.

The bolster 1 is secured to the body-support 5 thus formed by the pivot-bolt 24 extending through the registered orifices of the bearingdisk of the support and bridge-plate of the bolster. Thus constructed the support is adapted to be secured to the, front portion of the bottom of the body of a wagon, (not shown,) with the end portions of the front arms 19 in line at right angles to the sides of the body and with the arms 20 extending rearward of the front arms. In this position thecrossed rear arms form a strong brace for resisting any torsional strain caused by friction of the bearing in turning the bolster in either direction. The twists of the front arms also give increased strength to them in 1 10 resisting lateral strains, and by reason of these novel features of construction the support may be formed of lighter material, thereby reducing both the cost of material and construction.

By constructing the bolster of a single piece of strap-steel, as shown and described, the bending of which is readily accomplished, the assembling and riveting together of numerous parts are avoided, and the twists of the tongue-hounds and bridge-supports and the absence of rivets add greatly to the strength of the bolster, which also by reason of its novel construction may be formed of lighter material and at reduced cost.

What I claim to be new is 1. In a bolster and body-support for a childs wagon, the combination with abodysupport comprising a centrally-perforated bearing-plate and diverging arms secured to the bearing-plate, of a bolster comprising a single metal strap bent to form the parallel tongue-straps 3 at opposite ends of the central portion 2, the tonguehounds 4, the axlebearings 5, the bridge-supports 6 ,the parallel bridges 7, and the oppositely-extending trussarms 8 having the angled end portions 9, the end portions 9 and the tongue-straps 3 having perforations alined with the bearings 5, a

vbearing-plate 13 conjoining the bridges 7, and

means to pivot the bearling of the bolster to the bearing of the support.

2. In a bolster and body-support for a childs wagon, the combination with afrontaxle truss-bolster having a central bearing, of a body-support mounted on the bearing, comprising a bearing-disk and a pair of complementary truss-supports secured to the disk, said truss-supports each being formed of a single piece of metal strap bent to form an arm at each end of a central portion, said central portion being secured in parallel relation to the top of the disk-bearing, and the arms at one end of the base thus formed being reversely quartentwisted and relatively diverging laterally from the base, and the arms at the opposite end being bent at obtuse angles to the base, and relatively converging and crossing, all of the arms having their free end portions perforated and angled outward in a common plane, and a pin-bolt centrally pivoting the bearing of the bolster to the bearing of the support.

In witness whereof I have hereunto signed my name, in the presence of two subscribing witnesses, this 27th day of April, 1905.

OREL P. ERARD.
