J. THOMI. I AXLE LUBRIGATOR. APPLICATION FILED FEB. 18,1907.

UNITED STATES PATENT OFFICE.

' i'oHN THOMI, 0F BURNS, KANSAS.

AxLE-LUBmcA'roR.

,of Switzerland, residing at .Burns, in the county of Marion, State of Kansas, have invented certain new and useful Improve ments in AXle-Lubricators;' and Ido hereby declare the following to be a full, clear, and exact'desc'ription of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

he present invention relates to improvements in axle lubricators, and it aims to provide a simple, inexpensive, and eflicient device of that class by means of which, when in place, a lubricant may be freel su plied to the skeins on which the vehicle wiee'ls are mounted, without necessitating the removal ofthe latter, the device being particularly adapted-for use in connection with hard oil or grease.

A further object resides in the provision of a lubricating device in which the tube,

through which the grease is forced by the usual com ression cap, serves not only as a duct for th for preventing rotation of the spindle on the axle, acting, in this latter manner, as a key or s line.'

T1 e invention further consists in the construction, combination, and arrangements of parts, all as hereinafter more fully described, specifically claimed, and illustrated -in the I accompanying drawings, in which like parts are" designated by corresponding reference numerals in the several views.

of the said drawings-Figure 1 is a longitudinal section through the improved skein. Fig, 2 is a perspective view of the oil tube.

. Fig. 3 is a perspective view of the axle, showing 13, through which the lubricant is forced,-

'ing the groove formed therein. I

Referring more particularly to the drawings, the reference numeral 7 designates the skein in the boreof which is fitted the reduced end 8 of theaxle 9, the skeinbeing provided with an opening through which ex tends the stem 10 of an oil-cup 11, carrying the usual compression-cap 12; The stem of the oil-cup is provided with a central openand it\is provided in addition with a second opening 14, in which the upturned end 15 of an oil-tube 16 is fitted, the opposite end 17 of the oil-tube extending through an opening 18 formed through the skein. The oil-tube may be formed entirely independent of the skein, its end 17 being retained in the skein e lubricant but also as a means Patentedepril 21, 190s.

opening by any preferred means, or, if desired, the skein and oil-tube maybe formed from a single casting.

As shown in Fig. 2, both ends of the oil tube are completely-closed, while the upper surface thereof between the ends 15 and 17 is provided with a longitudinal groove 19, forming a duct, through which the lubricant is forced when the coin ression-cap is tightened in the oil-cup. e innermost end of the duct, so formed, is disposed directly beneath and in close proximity to the lower end of the opening 13 in the oil-cup, so that said duct and opening form a practically continuous channel. The skein is provided with a series of openings 20 formedtherethrough directly above the oil-tube, thus serving as outlet'ports for the lubricant.

From the foregoing, it will be ap arent that when the corn ression -cap is tig tened or moved downwar y in the oil-cu t'he lubrican-t contained in the latter will be forced through the opening 13 and duct be understood, however, as above stated, that the present invention is adapted espe, cially for use in connection with hart oil or gfiease, so that there will be no tendency of t e lubricant to be expressed through. the outlet ports unless the'com ression-eap is positively tightened in the oi -cup. The in vention, therefore, differs from lubricating devices in which a liquid lubricant is used, since, in the latter instance, there would be a tendency of the lubricant to flow continuously from the oil-cup and out through the ports, thus rendering the device useless and. defeating its purpose. I

As shown in Fig. 3, the tapered end of the axle is provided with a longitudinal roove 16, and finally through the outlet ports 20. it is to ter, in this way, acts similarly to a feather or s line, and thus serves to prevent any rotation of the skein upon the axle, it being un- ,derstood that the metal from which the oiltube is constructed has suflicient strength to serve such purpose.

What is claimed, is

1. The combination of a bored skein provided with an outlet port and with an opening located adjacent said ort; an oil-cup having its stein fitted i-nsaid o ening, said stern being provided with an out et ort and with an opening located adjace t t 1e same; an axle fitted within the skein re and provided witlra longitudinal groove; and an oiland oil-cup,

.rectly beneath the outlet ports in the skein turned, one of said ends being secured in the opening in the. oil-cup stem and the opposite end in the other opening in the skein to retain the tube in place and prevent rotating of the skein with respect to the axle, said tube having a longitudinal channel formed in its ulpper face directly beneath the ports in the s groove and provided 1n its upper face ditubefitted within said with a channel formed said tube having its opposite ends upturned, one of said ends being fitted in the'opening in,,t'he oil-cup stem and the other end being positively secured to the skein, to retain the tube in place and prevent rotation of the skein with respect to the axle.

2. The combination of a bored skein provided with aseri'es of outlet orts and with a pair of openings located a jacent the end ports of said series; an oil-cup having its stem fitted in one of said 0 enings, said stern being provided with an out et port and with a I ture, in presence of two witnesses. separate opening adjacent the same; a lon- JOHN THOMI. gitudinally-grooved axle fitted within the I skein bore; an oil-tube fitte'd' Within saidl groove and having its opposite ends upfl beneath the port in the oil-cup stem; and a compression cap calried by forcing the lubricant therein through said cup portand channel and out through said skein ports.

Witnesses:
