LUMBER-TRUCK.

SPECIFICATION forming'part of Letters Estant N o. 740,613, dated October 6, 1903. Application filed December l1, 1902. Serial No. 134,821. (No model.)

T a/ZZ whom, t may concern-.-

Be it known that I, JOSEPH BAKKER, a citi- Y specification.

My invention relates to mechanism for conveying lumber to and fro -between a lumber pile and car for loading or unloading the latter; and it has for its objects to produce a portable mechanism of this character which will be simple in construction and operation and which may be readily transferred from point to point as circumstances may require, the mechanism as a whole embracing an improved car for conveying the lumber and an improved track therefor of such construction that while being strong and durable it will be of sufficient lightness to insure its ready removal from place to place.

To these ends the invention comprises 'in a lumber-truck the combination, with a plurality of axles, of a horizontal brace-rod connecting the same and a roller mounted on said brac e-rod. v

The invention further comprises the details of construction and combination of parts more fully hereinafter described.

In the accompanying'drawings, Figure 1 is a side sectional elevation 4of my improved mechanism. Fig. 2 is a sectional end elevation of the same. Fig. 3 is a perspective view of the pivotal connection for the rail-sections Fig. 4; is a diagrammatic view illustrating the devicein Operation.

Referring to the drawings, 1 indicates my improved truck, comprising axles 2 2, having their ends bent downward and outward,for1ning spindles on which the supporting-wheels 3 are mounted. This manner of bending the axle produces arches a for the purpose hereinafter explained. 5 is a connecting-rod having reduced ends G, which are mounted inl bearings 7 formed at the center of the arched axles and receiving suitable nuts for securing the parts together. It is to be noted that the reduced ends 6, which receive the nuts, are shouldered, as at 8, to prevent the nuts binding against the axle. Mounted upon the rod 5 are a series of short rollers 9. These rollers are each preferablyT constructed of a suitable length of metal tubing having blocks Y '10 inserted and suitably secured in its ends,

the blocks being provided with a central hole by means of which they are journaled on the rod 5. of these rollers 9 as being mounted on the rod, it is to be understood that they may be substituted by a single roller, if so desired.

iVhile the above -described truck issusceptible of being employed-in connection with any suitable track, I prefer to use the one herein shown. This track comprises a plurality of rail-sections ll, of suitablelengths, arranged end to end and having their meeting ends pivot-ed. These sections may be pivoted in any suitable manner 5 but I prefer to form on the end of one section a round lug or pivotal axis 12, adapted to be seated within a socket 13, formed on the meeting end of the next section. I also bevel the vertical ends of the sections downward and away from the pivotal point, as' at 14, thus permitting one section to be moved vertically up or downward with relation to the other. I provide chairs formed for supporting the rails l1 by bending the lower end of a steel plate l5 outward to forma horizontal lateral ange 16, which lies beneath the rail. The plate 15 extends vertically upward along the side of the rail at a point near its top and is then bent inward and upward, as shown.

17 indicates brace rods having vertical downwardly-extending ends 18, which lie against the inner vertical faces of the plate 15. These braces extend obliquely upward to a point near the top of the plate 15, where they are provided with ears through which are passed rivets to secure them and the plate 15 together.

' 19 indicates rails,plates,and braces are securely connected together at the point where the rail-sections are pivoted together. The ends of the plates bolts or rivets by .which the` While I have illustrated a plurality I l5 are beveled, as at 20,vertically upward and TOO height at the pivotal point prevent the axles coming in contact with the tops of the plates when one rail-section is turned downward with relation to the other.

In operation the rail sections, which may be disengaged for transportation, are laid in two lines, as illustrated in Fig. 4, from the lumber-pile to the point to which the lumber is to be conveyed, and a truck is placed upon each of these lines, the lumber to be moved being loaded upon the two trucks with its ends resting upon the rollers f),carried by the respective trucks, and the trucks are moved forward by hand. Then the point at which the lumber is to be unloaded is reached, the rollers permit the lumber being shoved freely from the trucks, the lumber, of course, moving across the rollers transversely of the trucks,thus preventing any cramping' or binding of the parts. From this it will be seen that if the lumber is to be loaded onto a car or a dray the trucks may be brought to a suitable position at the end thereof and the lumber shoved freely from the same into the car or dray.

It will be seen that by the above construction I produce a very light and simple sectional track which may be readily disengaged for transportation and a truck which is admirably adapted for use in connection with this track, and it is to be understood that I connecting the same, and aroller mounted on the brace-rod.

2. In a lumber-truck, the combination with a plurality of axles, of a central horizontal,

rod connecting the same and a plurality of rollers mounted end to end upon said rod.

3. In a lumber-truck, the combination with a plurality of arched axles, of a horizontal brace-rod connecting the same, and a roller mounted on the brace-rod.

4. In a lumber-truck, the combination with a plurality of arched axles, of bearings carried thereby, a horizontal brace-rod mounted in said bearings, and a roller mounted on the brace-rod.

In testimony that I claim 'the foregoing as my own I have hereto atlixed my signature in the presence of two witnesses.
