IMPROVEMENT IN WAGON-AXLES.

The Schedule referred to in these Letters Patent and making part 'of the same.

To all whomit may concern v Be it known that we, GEORGE H. GLAD and JOHN CLBECKER, of Boston, in the county of Suolk and in the State of Massachusetts, have invented certainnew and useful Improvements in Wagon-Axles and l do hereby declare that the following is a full, clear, and

exact description thereof', reference being had to the accompanying drawing making a part of this speclcation, in which'- Figure 1 is a plan view Of the upper side of an axle with the skein in place;

Figure 2 is a vertical longitudinal section of the saine, on the line a* :c of iig. l; and

Figure 3 is a top View of the axle-arlnwith the skein removed. A

Letters of like name and kind refer to like parts in each of the figures. f

Our invention has for its object the lubrication of the journal of a wagonfaxle in a thorough and easy manner; and

It consists, principally, in the construction of the, plug used for closing the, upper end of the oil-c up, and

' in its combination with said cup, substantially as hereinafter shown.

It also consists in the construction of the oil-cup,

and in its combination with the grooved axle-arm, substantially as is hereinafter` shown, anclfor the purpose specified.

4 In the annexed drawing- A represents a inet-al axle, `having upon each end an arm, B, and a nut, G, of usual construction.

.Resting upon and secured to the upper side of the axle A, between its arms, is a bar Oi' wOOd,'D, upon each end of which is placed auoil-cup, E, havingthe general form shown in fig. 2, its upper half or cover, E', being detachable andsecured to said cup by means of the screws e passing through the former into the latter. v

Projecting downward and Outward from thelower side ofthe cup E is a lug, E", which terniinates'at the inner end of the axle-arm B, within the' face of the collar F, secured to and forming a part of the latter, and .serves to contain .an Opening, z, for the passage of oil from said cup to said arm.

From the outer end of said Opening z a half-round groove, G, extends along the arm B for a short dis tance, and then dividing the branches G, pass forward and downward in either direction until about Onehalf of an inch apart, and from thence extend Outward in slightly-diverging lines to apoint near the Outer end of said arm; e

By this arrangement Of the grooves the oil naturally flows outward and thoroughly oils the entire length of the bearing.

4Passimg; vertically downward through the'center of the cover E' of the oil-cnp is an opening, H, for the admission of Oil, which opening is provided with a female-screw thread, and has fitted thereto a plug, I, having upon its periphery a corresponding male-screw thread, said plug being so closely fitted to said Opeliing as to make between them a nearly air-tight joint. A small opening, ,'passing downward and inward, through the plug I, from a point alittle belowthe upper end of the screw;thread, completes the Oiling devicesz the Operation of which is as follows:

The cup being partly or entirely filled with oil, the plug is inserted and screwed downward, during which operation the air within .the cup escapes through' the openingA t while the upper end of said opening is above the Cover, after which, there being no vent for said air, it becomes compressed by the entrance within said cup of the lower end ofl said plug, and forces outward the oil contained therein.

When it is desired to again lubricatethc axle-arm, the plug is withdrawn' from the oil-cup until the u'pper end of the opening t' is above the latter, when, by rcturnin g said plug to its place, a supply of Oil is forced outward upon said axle-arrn`as before, the cup being capable Ot' a like operation until the Oil contained therein is entirely exhausted.

In Order that dust or other abrading substances may be prevented from entering upon the inner end ofthe axle-arm, a circular disk or. plate,'K, having a size corresponding to that of the inner end of the hub, is provided upon its inner fa'ceiwithv a recess which corresponds 'in size and shape with thecollar F, so that, when said disk is placed against the outer faceof` said collar, the latter shall be wholly contained within said said-recess, as shown inlig. 2.

As thus constructed, the disk K, heilig attached to the inner end of the h'ub by means of screws, serves' not only to exclude from the bearing all dust and dirt, hut also to firmly lock in place within-the hub the skein L.

Having thus fully set forth the nature and merits of our invention,

` I. In combination with the Oil-cup EA and E', the

plug I, provided with the opening t', substantially as shown and for the purpose set forth.

2. The Oilcup E and E', provided with the plug I and with the pertbrated lug E", in combination with the axle-arinB, provided with. the Oil-grooves G, substantially as and for the purpose shown.

In testimony that we claim the foregoing, we'have hereunto set our hands this 17thl day of J'une,w1870.
