COUPLING-POLE FOR LUMBER-WAGONS.

SPECIFICATION forming part of Letters Patent N0. 403,621, dated May 21, 1889.

Application filed March 8, 1889. Serial No. 302,512. (No model.)

To all whom it may concern:

Be it known that we, BENJAMIN R. STOGS- DILL and WILLIAM ANDREW WORLEY, citizens of the United States,residingat Carl J unction, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in the Coupling-Poles of Lumber or other WVagons; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to ll11- prove the means described in Patent No. 219,457, for supporting the friction-roller at tached to the coupling-pole of alumber-wagon, or any other to which it may be applicable.

Figure l of the drawingsis a perspective of the roller plate or support; Fig, 2, a similar view of the axiallyperforated friction -roll and its pivot, and Fig. 3 a similar view of said parts attached to the coupling-pole. Fig. 4 is a vertical section.

In the drawings,A represents the couplingpole with the shallow recess a to receive the plate, the ends being flush with the top of the pole and fastened by the bolts 0 and nuts D, or other suitable means. The plate B has an upwardly-convexed and transversely-curved projection, 19, with the longitudinal slot b for the frictional roll E, and the holes 6' b to receive the roller-pivot F. The latter is squarenecked, so that it cannot turn in its correfriction-roll turning upon a fixed spondingly-shaped hole, and threaded at one end to receive the nut G, while it is provided with a head at the other end. The body of this fixed pivot passes through the axial hole 6 of the roll E, so that the latter can freely revolve upon it. By this construction and combination of the parts we avoid all unnecessary weakening of the pole where the roller is seated. The-roller-plate being in one piece avoids the separation of parts, so that the j ournals will cramp, and the axially-perforated roll, with fixed pivot, renders it unnecessary to remove the whole plate when the pivot-bolt becomes worn or out of kelter, as is the case when the journals are a part of the roll. The l'ollensupport will thus last much longer, be much stronger, be more easily put in place, and be less liable to get out of order.

Having thus described all that is necessary to a full understanding of our invention, what we claim as new, and desire to protect by Letters Patent, is

The metallic plate B, formed with fiat ends to fasten to the coupling-pole, and an intermediate raised or convexed part, b, with the longitudinal slot 6 and journal or pivot holes U W, in combination with an axially-perforated pivot, as shown and described.

In testimony whereof we affix our signatures
