WAGON BOLSTER Filed July 2, 1950 2 Sheets-Sheet 2 Patented li/iay l, 1934 1 Claim.

This invention relates to channel iron wagon bolsters and particularly to the manner of attaching the wagon stakes thereto.

One of the objects of the invention lies in the provision of channel iron wagon bolsters so arranged as to receive the depending lower ends of wagon stakes therein in a fixed and immovable manner.

Another object lies in the provision of channel iron wagon bolsters formed with the said portions channeled out, the channeled-out formation, however, permitting the attachment thereto in an immovable manner of the depending lower end of tubular wagon stakes.

Still another object lies in the provision of channel iron wagon bolsters, the channeled portions being channeled-in as well as arranged to receive in a and immovable manner the depending lower ends of tubular wagon stakes.

A further object lies in the method of attachment of tubular wagon stakes to channeled bolster portions.

Other objects will appear in the following specification taken in connection with the annexed drawings, in which Fig. 1 is an elevational view of one manner of attachment of tubular wagon stakes to the channeled bolster portions;

Fig. 2 is a plan view thereof;

Fig. 3 is an elevational view showing a second manner or" attachment of tubular wagon bolster stakes to a channeled-out bolster frame;

Fig. 4 is a plan view thereof;

Fig. 5 is another elevational view showing the manner of attaching the lower ends of tubular wagon stakes to a channeled out bolster;

Fig. 6 is a plan view thereof;

Fig. 7 is a cross-sectional view taken on the line 77 of Fig. 1;

Fig. 8 is a cross-sectional view on the line 88 of Fig. 3;

Fig. 9 is a cross-sectional view taken on the line 9--9 of Fig. 5.

Before referring specifically to the drawings,

' it might be stated that the present applicant has been extremely active in experimental work as well as production of steel wagon trucks, wherein channel members are used substantially throughout. The use of channeled members in the construction of steel trucks has permitted the manufacture of such trucks at a lower cost and with greatly increased production. The use of such members in applicants novel manner has greatly assisted in the assembly of the truck,

" which in turn has been strengthened materially and at the same time been produced with a greatly decreased weight.

The present application is directed particularly to the manner of attachment of tubular stake members to the wagon frame or bolster. Con- 6,0 ventional stake construction comprises either a cast or channeled stake usually bolted to the bolster. Applicant in the present instance has constructed the bolster of channeled members, in some instances channeled-in and in other in stances channeled-out.

The tubular wagon stakes have been secured to the bolster in such novel manner that they not only assist in the formation and strengthening of the bolster, but also are disposed in their conventional position and for the usual purpose of receiving the wagon box, which is placed upon the bolster in a removable manner.

Referring specifically to the drawings, in Fig. 1 is shown a bolster formed of two opposed channeled in portions, namely 10 and 11. These channels are secured at an intermediate point by means of the bracket 12 and plural bolt members 13. However, at their outer ends they are secured as well as strengthened by the particular 86 manner in which the wagon stakes 14 are secured at their lower ends between the opposed open ends of the channel portions. In this instance the channeled-in portions of the bolster are cut away interiorly as at 15 in an arcuate manner to 5 receive the lower ends of the tubular stakes. In this manner displacement of the stakes with respect to the bolster is prevented laterally and the further tying up of the stake with the bolster is accomplished by means or" transversely disposed on bolts 16.

In Figs. 3 and 4, the bolster is shown formed of opposed channeled-out members 17 and 18. The channels in this instance are forged at their outer ends to form somewhat similar arcuately shaped portions 19, which also receive the depending lower ends of the tubular wagon stakes 20, the forging of the ends of the channels in the manner escribed also preventing lateral displacement of the stakes, and the final tying up of the stake mg with the bolster is accomplished likewise by transversely disposed bolts 21.

In Fig. 5 a somewhat dilierent manner of attachment oi the stakes is disclosed. In this instance the bolster is formed of opposed channeled-out members 22 and 23. Between the open outer ends of the channels are disposed the lower and flattened depending lower ends of the wagon stakes 24, the final connection between the stakes and the channeled-out bolster member being 8.0- 5 1 complished by the plural bolt members 25, per haps most clearly shown in Fig. 9. Usually, under such circumstances; the final assembly may be accomplished without the insertion of the lugs or ferrules 26 disposed inwardly of the flattened ends of the wagon stakes. However, the disposition of these lugs or ferrules within the flattened ends of the wagon stakes and in a manner to receive the plural bolt members therein accomplishes an assembly of increased strength and of a somewhat sturdier construction.

In Figs. '7 and 8, which are cross sections of the bolster and stake assemblies shown in Figs. 1 and 3, the manner of securing the lower ends of the wagon stakes to the bolsters is thought very clearly shown.

In view of the above description and the degree of detail disclosed in the drawings, the operations necessary in the assembly of the wagon stakes with the channeled-in or channeled-out members, are thought obvious and it has not been considered necessary to describe same.

What I claim is:

A wagon bolster-tubular stake assembly comprising dual substantially parallel channel members and tubular stakes, the channel members having, adjacent their ends, axially parallel arcuate depressions in the faces of the web portion thereof, the depressions-being so formed and disposed as to receivea'nd partly surround the lower ends of the tubular stakes when same are disposed between the channel members with the flange portion of the channel members turned outwardly, and means for clamping the said channel members upon the stake members to securely hold the same therebetween- DANIEL W.
