i To ali whom it may concern;
Beitrknown that I, HENRY Milford, in the county of New Haven and State'of a Connecticut, have invented and made a newand userind ,ffilit HENRY e1; THOMPSON, or;
MILFQRD, ooNNEoTIoUn Letters Patent No. 112,511, dated March 7, 1871.
i I'MPROVEMENTJN-(tQOLlNG JOURNALS or CAR-AXLES.
The Schedule referred to in these Letters-Patent and making part of the same.
G. THOMPSON, of
ful: Improvement in Cooling Journals-of Oar-wheel Axles, and the following is hereby declared to be a 9 correct description of the sanie. I i
3 Before my invention,the journals of paddle-wheel shafts had been made with a n openingthrough them,
in which water was caused to circulate, but'this device could only be used where a supply of water was easily accessible. i a 3 r Railroad, car axles have been made hollow, to contain lubricating material, and they have, been connect- "ed toa vessel to holdwater, sovthat water could run into theaxle; hutthese devices do not operate prace 3 tioally to attain the object sought by me. p i
I make use of the centrifugal aetion of the oar-wheel and axle to produce a current of air through the hollow axle to keep it coolpand I also inject through the hollow axle acurrentbf airfderived from the: move ment'of the car,'a nozzle-t'ubebeing provided that passes across the, journal-box and enters the holein the axle, and a movable funnel outside thebox causesthe air to be driven through said tubular nozzle and hollow axle and escape by the lateral passages; By
this means the dust cannot :get into the journal-box, j becausefche tnbularvn ozzle acts as an injector-to blow through theihollow axle, thereby avoiding risk of dust and particles of sand getting into the oihand the cur-.
rent of air keeps the journal cool.
a In the drawing- 3 1 t Figure 1, is a vertical sectionof a ournal and box of an axle, as made w h my-in1provemc nt,and Figure 2 isa plan ot'the same. The cal-wheel axle is provided with journals, as mun. The axle a is represented as beneath the bearing-block b; and the box 0, for the lubricating material, and the cap 11, are of ordinary construction.
The journal of the axle has a hole, '5, running. centrally through it, with the lateral openingsc e, for
the discharge of air by centrifugal force, producing a current through the hole t to keep the axle cool.
The tube j; passing through the box'c or its cap it, is provided to supp]; air to the hole i and prevent dust enteriug the box '0, and the'funuel-shaped injector g may-also beemployed, the same being connected by a bend, l, and coupling with the tube f, so that it may be reversed, according to the direction in which the caris moving. I A screen of wireisto be applied at the mouth of the funnel at a, to prevent sand or foreign substances passing into thetube The tube -f must be smaller than theopening '8, so-
as to act as a nozzle in blowing, through the hollow axle, and prevent dust or grit returning into the oil receptacle.
I claim. as my invention 1. The tubular nozzle f, passingthrough the journal-box and entering the hole '6, and acting as an injector to force a current of air through the hollow journal and outat the lateral openings, to keep the journal cool and prevent dust passing into the journalbox, as set forth.
' 2. A perforated screen, introduced in the air-pas.- sage, to exclude foreign substances, in combination with the tubular injector-nozzle f and hollow journal, as and for the purposes set forth.
, Signed by me this 28th day of September, 1870.
