SPlNDLE-BEARING.

SPECIFICATION forming part of Letters Patent No. 669,655, dated March 12, 1901.

Application filed. November 15, 1900.

To aZZ whom, it may concern:

Be it known that I, JACOB M. OLINGER, a citizen of the United States, residing at Vienna Crossroads, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Spindle-Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to spindle-bearings for disks employed as furrow-openers for grain-drills and for other purposes and for wheel-bearings in general, and has for its object to provide means for efficiently lubricating the bearing with the consumption of a relativelysmall amount of lubricating material.

To this end the invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a disk having my improved bearing applied thereto. Fig. 2 is an edge View of the same. Fig. 3 is a view of one end of the bearing. Fig. 4 is a view of the other end thereof. Fig. 5 is side elevation of the bearing. Fig. 6 is a sectional View taken on the line 6 6 of Fig. 4. Fig. 7 is a sectional view taken on the line 7 7 of Fig. 6. Fig. 8 is a detail plan view of the spindle detached. Fig. 9 is a sectional view taken on the line 9 9 of Fig. 8. Fig. 10 is a View illustrating one way of mounting the device. Fig. 11 is a view illustrating the device as applied to the bearing of a vehicle-wheel. Fig. 12 is a sectional view similar to Fig. 7, illustrating amodification. Fig. 13 is a sectional view taken on the line 13 13 of Fig. 12. Fig. 14 is a plan view of the modified form-of spindle detached. Fig. 15 is an inverted plan view of the same; and Fig. 16 is a sectionalview of the same, taken on the line 16 16 of Fig. 14.

In the said drawings Ihave shown in Figs. 1 to 9, inclusive, a construction embodying my invention in its preferred form. In this construction 1 indicates the disk, which is preferably of the usualconcavo-convex form, and 2 the hub thereoflprovided with the usual Serial No. 36,556. (No model.)

radial flange 3, by means of which the disk proper and the hub are secured together by riveting or otherwise. The body portion 4 of the hub is hollow and cylindrical in form and is adapted to receive and fit upon a bearing sleeve or spindle 5 on which it rests. The spindle 5 is provided at one end with a head 6, preferably of about the same diameter as the body 4 of the hub, and in the same end of said spindle is formed a square or polygonal aperture 7. The other end of the spindle is provided with an aperture 8. The interior of the spindle 5 is hollow, forming a chamber or recess 9. A. slot or opening 10 extends from said chamber or recess to the top of the spindle, and a second slot or opening 11 extends from said recess or chamber to the bottom of said spindle. The outer surface of the spindle is cut away for some little distance back of the rear edge of the mouth of the slot 10, as indicated at 12, while the opposite or front edge 13 extends to a contact with the inner surface of the hub and acts to some extent as ascraper. There is provided in the body of the hub an oil-inlet aperture 14, closed by a screw 15 or other suitable closure. The interior chamber 9 of the spindle is provided with a lining or body of felt 16 or other suitable fibrous material, having a downwardly-extending portion 17, which fits within the slot 11 and extends to the bearing-surfaces of the spindle and hub. The body of felt has a central aperture for the passage of the retaining-bolt hereinafter described, and its upper edges abut against shoulders 18, formed in the upper part of the chamber and serving to hold the felt in position and prevent slipping.

A washer 19 fits within the outer end of the hub 2 and has an annular extension or collar 20 extending into the aperture 8 of the spindle and is further provided with an aperture 21 for the passage of the retaining-bolt. A packing 22, of leather or other suitable material, is interposed between the meeting faces of the spindle and Washer to prevent escape of the oil or other lubricant. The washer projects slightly beyond the hub to prevent binding of this latter when the parts are assembled.

The bearing may be supported in any suitable manneras, forinstance, in the manner shown in Fig. 10, in which the bearing-spindle and its washer are clamped between the drag-bars 23 by means of a bolt 24, passing through the bars and bearing, having a squared or polygonal portion 25 to fit the aperture 7 and prevent the spindle from turning, and provided with a nut 26.

The bearing thus constructed operates in the following manner: The lubricant is introduced by removing the screw 15 and turning the disk so as to cause the aperture 14 to register with the groove 10, the screw being replaced after the proper amount of oil has been poured in. The oil passes down into the chamber 9 and through the felt l6 and its extension 17 to the bearing-surfaces by way of the slot 11. The felt retards the flow and prevents the delivery of the oil in excessive quantities. The oil is carried up by the rotation of the disk and again delivered to the chamber of the spindle by way of the slot 10, so that the oil is used over and over again. This gathering in of the oil is facilitated by reason of the cutting away of the spindle at one side of the mouth of the inlet-slot, since the disk when at work revolves in the direction of the arrow in Fig. '7, so that the oil carried up by the rotating hub is to a considerable extent deposited in this cut-away portion and flows thence into the slot. The scraping edge 13 also aids in directing the oil into the slot in an obvious manner. I have found by practical experience that a bearing constructed in accordance with my invention will remain properly lubricated when supplied with a given amount of oil for a much longer period than the bearings now in common use.

The details of the invention may obviously be varied without departing from the principle of my invention, and as an illustration of this I have shown in Figs. 12 to 16, inclusive, a modified construction in which instead of the slot 10 I employ a groove 27, communicating with the inner chamber of the spindle by apertures 28. In this construction the cut-away portion 12 is dispensed with, as are also the shoulders 18. The structure is also adapted for use as a bearing for general use in connection with vehicle and other wheels, and in Fig. 11 I have shown such a construction, which Will be readily understood in connection with the preceding description without further detailed explanation.

Other modifications will readily suggest themselves, and I therefore do not Wish to be understood as limiting myself to the precise details hereinbefore described, and shown in the drawings.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is
