` Application llled` 11.11104,

`This invention relates to vehicles, and particularly to the connection between the traction members and the body part. Al though applicable to various types of'vehicles, the invention is of especial value in` connection with small vehiclesfor children, where a light, yetL strong and durable construction is desirable.

An objectof the invention is to provide an improved construction of bolster and bracing for vehicles, which `will require little material; which will be light in weight, rigid, durable, and strong; which may be made attractive in appearance; and which is relatively inexpensive. Various other objects and advantages will appear as the description of the invention proceeds, and the novel features will be particularly pointed out hereinafter in appended claim.

In the accompanying drawing:

Figure 1 is a longitudinal sectional elevation of the rear end of a childs vehicle, constructed in accordance with the invention, the elevation representing a section taken approximately along the line 1 1- of Fig. 2.

2 is a transverse sectional elevation of the same, the lineof section being approximately along the line 2-2 of Fig. 1.

Fig. 3 is a sectional elevation, on a slightly larger scale, of a portion of the construction, and

Fig. 4 is a front elevation of the shown in Fig.`3.

In the illustrated embodiment of the invention, the seat, platform or body part 1 of thevehicle ,may be of any shape or material, and is usually although not necessarily of wood. A strip 2 of fiat sheet metal is bent upon itself into a somewhat U-shaped form of belsterpiece, the upper or free ends of the arms thereof being bent toward one another to form angular terminals 3, which are secured against the under face of the seat 1 in any suitable manner such as by screws 4. A metallic tube 5 passes through apertures 6 in the opposite arms of the strip, near the bottom or cross portion 7, and, is slightly longer than the distance between the outer faces of the arms where` itpasses through them. The ends of the tubes are upset or expanded, so that the tube cannot be displaced or removed.

Bearing pins or axles 8 extend into the ends of the tube so as to project therefrom, and suitable means such as cotter pins 9 pass part 1924. serial N o. 71,616,776.

-throughaligned apertures in the tube, axle pins and cross part 7 of the U-shaped bolster piece, so as to secure them alltogether and the pins within the tube. Suitable traction members, such as wheels l0, arerotatably `mounted upon the projecting ends of the bearing pins. The faces of the depending arms 11 and the cross portion 7 of the bolster piece, are preferably provided with one or more corrugations l2 running lengthwise thereof. so as to increase their rigidity, strength, and resistance to lexure. The depending arms 11 may also be bowed toward one another to improve their appearance.

\ The cross portion 7 of the bolster piece, at opposite sides of its center, preferably near its ends, is provided with apertures 13. A. pair of brace strips 14 have .reduced tongues 15 which pass through and are anchored in the apertures, such as by clinching, and at their free ends are preferably, separately of one another, secured by suitable means such as screws 16 to the under face of the seat 1, forwardly of the bolster piece. The brace strips 1li are also preferably provided in their faces `with one or more longitudinal corrugations 17 which increase their rigidity and resistance to fiexure.

The brace strips are preferably attached after the bolster piece has been attached to the seat, the tongues 15 being yinserted through the apertures 13 and then secured to the seat 1. over before the other ends are secured to the seat, but I have found that if the clinching is done afterward, the braces may be drawn tight by the mere act of clinching, which increases the rigidity of the resulting structure. The upper ends of the braces may be securedto the seat by a single screw. but I have found thatby using separate securing means the screws will not loosen as quickly as if used to secure several braces. This is apparently due to the fact that a screw will not loosen or pull out as quickly when the pull is in one direction only, as when it is in a plurality of directions.

The tubular member 5 adds considerable `strength to the structure, and permits the The tongues 15 may be clinched` tirely through the tube may be used if desired. The entire construction can be made from stock material such as rolled strips of metal and standard tubing, and the strips of metal may be stamped and bent by dies to their proper shape and size. The structure is therefore relatively inexpensive, and has lightness, strength and rigidity. The side arms of the bolster piece may be given graceful curves so as to make the structure attractive jin appearance.

It Will be understood that various changes in the details which have been herein described and illustrated for the purpose of explaining the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the claim hereto a pended and forming a part of this speci cation.

I claim: l

In a juvenile vehicle, aflat metal strip bent upon itself to form a bolster piece, a tube passing throu h and connecting the opposite sides of the lower portion, bearing shafts disposed in the ends of the tube and projecting from the ends of the latter, traction members carried by the pro'ecting ends of the shafts, and a locking e ement passing through the tube, shafts and strip for securing them all together.

n testimony whereof I have hereunto set my hand.

CLARENCE WATSON WHITE.
