LUBRICATING CARRIAGE-AXLES.

Specification of Letters Patent No. 27,785, dated April 10, 1860.

"To all whom it may concern:

Be it known that 1, JAMES EMERSON, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvement in Lubricating the Axles of Vehicles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, forming a part of this specification, in. which Figure 1 represents a central section taken through the hub of a wheel for a carriage, showing the axle in the same, and the device for supplying oil to the axle. Fig. 2 is an enlarged View of the tube and valve arrangement detached from the hub, showing the valve and stem in two positions, one when the oil is allowed to flow from the tube, and the other position when the flow of oil is stopped.

Similar letters of reference indicate corresponding parts in both figures.

The object of. this invention is to provide a cheap, compact, and efficient self oiling device which is to be arranged in such a relation to the axle of the wheel as to supply oil to the same without removing the wheel as is at present done, before the axle can be perfectly oiled. My invention provides for supplying the axle whenever necessary either on the road or in the carriage house; and by simply moving a thumb screw, a free supply of fresh and pure oil may be supplied to the axle, at the same time the impure oil on the axle cannot enter the feeding box. I

For this purpose my invention consists in the employment of a suitable oil receptacle, with a peculiar valve stem, and valve with a screw cap, arranged in such a way, and introduced through the hub and axle box as to be free from injury, and so as not to be affected by the wear of the axle box as will be hereinafter described and represented.

In the drawings A represents an ordinary hub of a carriage, B, the axle, and C, the axle box. These parts are in common with those of any ordinary vehicle, and are represented in the drawings merely to illustrate more clearly my self oiling device. This device consists of a metal tube E, which is bored nearly through, leaving a portion F, with a small hole a, punched through it, communicating with the oil receptacle, this end of the tube has a screw thread cut on it, which is tapped through the axle box C, as shown by Fig. 1. In the top of tube E is screwed a cap G, with a long screw neck to which is secured the stem J. This stem passes down through the center of the tube, and at c, is an enlargement forming a valve, having its seat in the portion F, the stem continues down through the perforation a, in tube E, and terminates at the bottom of the tube.

The hub A is bored out to receive the tube A, which is fitted into this hole, and secured by screwing it through the axle box C, as shown and described, the thumb screw, or cap G, being the only portion of the device which is in sight.

It will be seen from this description of my selfoiling device for carriage hubs, or for oiling axles, or shafts of any description, that by loosening the cap Gr, sufficiently to raise the valve 0, from its seat, the oil may be supplied to the axle rapidly, or as slow as may be desired, the tube or oil receptacle may be made sufliciently large to contain a good supply of oil, which will be kept closed, and free from dirt, so that pure oil only will be supplied to the axle, the short stem between the valve and axle, will prevent the used up oil or tar in the axle box, from entering the tube E, and this portion of the valve stem serves as a guide for the valve, and this, with the portion F, of the tube E, allows for any wear in the axle box, without injury to the perfect operation of the parts. The cap can be removed, and the tube may be filled with oil at any time, and the axle may 'be oiled when the vehicle is in motion, whenever it requires it.

These devices can be manufactured and sold very cheap, and when once applied to a set of wheels, will last as long, or longer than the wheels, saving much time and trouble of axle by means of a screw cap, valve stem and valve, arranged and operating essenl0 tially as set forth, and for the purposes described.
