LUMBER-TRUCK.
SPECIFICATION forming part of Letters Patent No. 569,962, dated October 20, 1896.
Application filed March 6,1896. Serial No. 582,122. (No model.)
To all whom, it maz concern:
Be it known that I, VIoToR'L. EMERSON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have in vented certain new and useful Improvements in Lumber-Trucks, of which the following is a specification.
This invention relates to a lumber-truck for use in dry-kilns. In kilns for drying lumber track-rails are usually laid, and special trucks are placed on these rails and the lumber is piled on the trucks. By this means the handling of the lumber incident to the drying operation is facilitated.
The present invention relates to an improved truck of the bicycle class in which two flanged wheels are placed in alinement and secured in a strong frame.
The invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the truck. Fig. 2 is a top view of the truck. Fig. 3 is a perspective view of the union stay-piece. Fig. 4 is a vertical cross-section of the truck through the union stay-piece. Fig. 5 shows two trucks and a lumber-supporting beam extending from one to the other. Fig. 6 is a view of a stack of lumber piled endwise on four of the trucks.
The truck comprises two longitudinal channel-beams A, each provided with a central hole I), and near each end ahole 0. The inner vertical face d of each beam is flat and the outer face has two flanges e. A union stay-piece F has position between those two beams at their center and is the only piece which separates the two beams. This union stay-piece has two sides g, which fit close against the inner vertical faces d of the beams, and each of the two sides have four lateral projecting lugs h h, which are located, as it were, one at each corner. (See Fig. 3.) The two upper lugs h at one side take over the top of one beam and the other two, h,take under the bottom of the-beam, (see Fig. 1,) and thus the beam A at one side fits snugly between the said two upper and the two lower lugs. Both beams A fit in the same manner. The union stay-piece also has a central transverse hole I), and a bolt 12 passes through said hole and its ends enter and fit in the central holes I) in the two beams. On the staypieee are four cross-ribs j, each extending from one of the projecting lugs at one side to the corresponding lug at the opposite side. The upper cross-ribsj project above the top of the two beams A, and in like manner the lower cross-ribs project down below the bottom of said two beams. By having these cross-ribs to project higher than the top surface of the longitudinal beams they serve as a stop-shoulder for the lumber-supporting beam K and prevent said beam from slipping against either of the wheels L. The two wheels are in alinelnent between the two channel-beams A and revolve in a plane which is parallel with the said beams. Each wheel turns on an axle-bolt 0, whose ends project through the holes 0 in the two beams, and is secured by riveting the end. Thus the two axle-bolts serve to bind the longitudinal beams A together against the central stay piece F. The wheels are double-flanged to keep their position on the track-rails m.
The construction of the union stay-piece with a fiat side g and four lugs h h enables the two side beams A to be very firmly attached. The four lugs at each side take onto the beams and thereby prevent any displacement, torsional or otherwise. The central bolt 19 takes into theholes I) prepared in the beams and insures that all the parts have the.
proper relation or proper position, and by having the ends of this bolt riveted it assists to bind the parts. These small trucks may be used either side up and each separate from the lumber-supporting beam. By this ar rangement the small trucks when unloaded can be located at any desired point under a lumber pile, and can be more conveniently returned to the receiving end of the dry-kiln. Ordinarilyfourof these separate trucks will suffice for a stack of lumber that is to be dried.
The wheels are preferable provided in their hubs with rollers which constitute an antifriction-bearing on the axle-bolts. These rollers are not shown in the drawings because their construction is old and well known.
Fig. 5 shows an end view of two trucks connected by a lumber-supporting beam K, and Fig. 6 illustrates a stack of lumber piled lengthwise on two of such lumber-supporting beams and four trucks.
Having thus described my irwention, I claim- 1. A lumber-truck for dry-kilns having two longitudinal beams; two wheels in alinement between the said beams and revolving in a plane which is parallel with said beams; a union stay-piece between the two beams and also between the wheels, said stay-piece having lateral projecting lugs at opposite sides which take both above and below the said beams; and an axle-bolt at each end through each wheel and also through the two beams.
2. A lu mber-truck for dry-kilns having two longitudinal beams; two wheels in alinement between the said beams and revolving in a plane which is parallel with said beams; a union stay-piece between the two beams and also between the wheels and provided with stop-shoulders to prevent a lumber-supporting beam from slipping; and bolts confining the two beams together.
3. A lumber-truck for dry-kilns having two longitudinal beams; two wheels in alinement between the said beams and revolving in a plane which is parallel with said beams; a union stay-piece between thetwo beams and also between the wheels, said stay-piece having lateral projecting lugs at opposite sides which take both above and below the said beams and also having stop-shoulders to prevent a lumbei supporting beam from slippm g.
scenes 4. A lumbertruck for dry-kilns having in combination two longitudinal bars; two wheels in alinement with each other between the said bars and projecting above the top thereof and revoluble in a plane parallel with said bars; means connecting the two bars to hold them in their proper relative position, and stop-shoulders to prevent a lumber-supporting beam that may rest upon the truck from slipping against the wheels, as set forth.
5. Alumber-truck for dry-kilns having two parallel beams; two wheels in alinement between said two beams; and one stay-piece centrally placed between the beams and also between the wheels and provided above and below with stop-shoulders to prevent a lumber-supporting beam from slipping, whereby the truck may be reversed and used either side uppermost.
0. Alumber-truck for dry-kilns having two parallel beams; a distance-piece separating said beams and having lateral lugs which project and engage with the edge of said beams; and two wheels in alinement between said beams and revolving in a plane parallel therewith.
In testimony whereof I aliix my signature in the presence of two witnesses.
