ROLLING SPECIFICATION forming part ofIetters Patent No. 255,081, dated March 14, 1882 'COLTER.

Application filed December 9, 1881. (No model.)

To all whom it may concern Be it known that I, FRANKLIN B. HUNT, of

Richmond,in the county of Wayne and State of Indiana, have invented certain Improvements in Rolling Oolters, of which the following is a specification.

My invention relates to improvements in journalin g circular colters to the yokes by which they are secured to plows to adapt them to withstand the increased strains to which they are subjected by use upon wheel'plows, and also to provide ajourna-l and bearings which will operate without the use of oil, allas hereinafter fully described and set forth in the specification and claims.

Figure 1 is a longitudinal vertical section through the axis of the colter and adjacent mechanism. Fig. 2 is a perspective of the colter-shank and a portion of the upper end of the yoke by which the colter is suspended. Fig. 3 is a perspective of the colter-shank by which the col ter is suspended from the plowbeam. Fig. 4 is a plan ot'one-half of the colteryoke. Figs. 5 and 6 are longitudinal sections of modifications of the invention.

A is the rolling colter. B is the shank by which the colter is suspended from the plowbeam by means of the arms 0, forming a colteryoke. These arms 0 are cast in pairs, one of which is seen at Fig. 4., and provided with the hollow part P, which hollow parts P are provided with cups or recesses H for the cushions I, as seen in Figs. 1, 5 and 6. The upper ends of these arms 0 are provided with an elongated head, T, as seen in Figs. 2 and 4. These elongated ends are provided with holes F for the bolts G. The center of this head is provided with a half-circle hearing or recess, E, which, when the arms are put together and in place, forms'acircle and fits on the neck F ofthe shank B to form a colter-yoke. The neck F is pro, vided with an elongated head, D, which rests between the arms 0, as seen at Fig 2, and, being slightly tapering toward the ends, allows the arms 0, forming the colter-yoke and carrying the colter, to vibrate sufficiently for the colter to adjust itself at all times to the line of draft, and also holds the yoke upon the neck F of the shank B. The arms O are cast, preferably of steel,to stand great strain, and formed ready for use without fitting, and provided with the holes F F, recesses E for the neck F, and recesses H for the cushions I. Figs.5 and 6 are modifications of Fig. 1. In Fig. 1, J arcjournals with flanges to rest against the colter, and attached thereto in any suitable manner. The bearings K K for the journals J are made of hard wood, and boiled in tallow and plumbago to form a bearing for the journals which does not require oil, this being a great desideratum, as the carelessness or neglect of operatives to properly oil the journals of a rolling colter causes it to cutout rapidly, as it is continually exposed to dirt and grit from the soil. The cushions 1 rest against the flanges of thejournals J. The cups or recesses H extend over the cushions and embrace the edges of the flanges. The shoulders or hottoms M of the cups H press against the outer portion of the cushions, and the wooden bearings K press against the inner portion of the cushions by means of the hollow screw-plugs L L pressing against thebearings. The bolt N has its bearing in the hollow screw-plugs L L alone to prevent all contact or frictionwith the bearing J J and KK,'and it will be readily seen that the office of this bolt is to clamp the outer edge of the cushions through the means of the screw-plugs L and bottom M of the cups or recesses. The socketed parts P P, attached to the lower ends of the arms'O, are threaded at their outer ends. to receive the hollow screw-plugs L L. The inner edges of the recesses H lap over the edges of the flanges of the bearing J, and keep out the greater portion of the dirt, and the cushions fitting snugly in their places, as plainly seen at Fig. 1, makea journal-bearing absolutely dust-proof.

The cushions I may be made of leather, rubber, or any suitable material.

The wooden bearings K may be replaced with metal bearingsfand oil used, if desired, as the journals arefree from dust; butI greatly prefer the wood, as it suffers no harm from neglect.

The inner surfaces of the'socketed parts P P for the bearings Kma y be made square, octagonal, or any other desired shape.

Fig. 6 represents another construction of wooden bearings for the colter-journal, with I00 cups or recesses, as above, attached to the arms O for the cushions I, and provided with wooden hearings K and screw-plugs L.

Fig. 5 represents threaded metal bearings "R R, held in place, when adjusted, by means of B, provided with the neck F, and elongated head D, and bolts G, substantially as set forth.

2. In combination with the journal of the rolling" colter A, the cups H, cushions I, bearings K. andscrew plugs L, substantially as set forth.

3. In combination with the rolling colter and the'socketcd part P, the cushions I, wooden bearings K, and screw-plugs L, substantially as set forth.

4. In combination with the rolling colter and socketed part I, the wooden bearings K K, hollow screw-plugs L L, and bolt N, substantially as shown and described.

5. In combination with the socketed part P and the bearings J of the rolling colter, the wooken bearings K, cushions I, and screwplugs L, substantially as set forth.

6. The cups H, arranged to pass beyond the cushions I and embrace the flanges of the bearings J, in combination with said cushions, bearings K, and screw-plugs L, substantially as shown and described.

7. The cups H, arranged to pass beyond the cushions I and embrace the flanges of the bearings J, in combination with said cushions, bearings K, screw-plugs L, and bolt N, substantially as set forth.

8. In combination with the arms 0 O and socketed portionsIP, provided with the screwplugs L L, the boltN, substantially as shown and described.

9. In combination with the arms 0 O and socketed portions P P, provided with thescrewplugs L L and cups or recesses H H, the bearings J K, cushions I I, and bolt N, substantially asset forth.

10. In combination with the socketed portions P I, provided with the recesses H and cushions I, the screw-plugs L L, and bolt N, substantially as shown and described.
