A Tra @NEX CHARLES B. MCKOWN' OF INDIANAPOLIS, INDIANA.
'Specivcaton of Letters Patent.
Patented July 31,1906.
Application filed August 30,1904. Serial No. 222.744.
To all whom it may concern:
Be it known that I, CHARLES B. 'McKowN, a citizen of the United States,'residing at Indiana olis, in the county of Marion and State of In iana, have invented certain new and useful Improvements in Self-Lubricating Pulleys, of which the following is a specification.
The object of this invention is to provide a supply of oil suitable for several days run of the pulley Without renewal and to rovide an automatlc means for distributing t e oil from said place of sup ly to the rubbing parts', so as to reduce the fiiction at said places.
I accomplish the objects-by the mechanism illustrated in the accompanying drawin s, in which'- i A igure 1 is a vertical section of my invention through the axis of rotation of the pulley, and Fig. 2 is a like view of a modlfied' construction of same.
Like characters of reference indicate like parts throughout both views of the drawmgsp 3 is the shaft, on which the pulley ismounted, and 4 is a spool, which is mounted on the shaft and fixed thereto by any suitable means, the means here shown being the set-screws 5 5,' which enter socketsl in the shaft. The s ool 4 will preferably have the integral ange 6 at one end and the removable flange 7 at the other, the latter flange being secured by screwsl 8, as shown.
9 is the pulley, which has a web of ,suchv thickness as to make a close fit between the flanges 6 and 7 on the spool 4, on which s ool said pulle is mounted, the bore of the pu ley being suc as to make a close-running fit on said spool.I As is obvious from the construction, the spoolsl will first be fastened, by means of its set-screws, in the desired osition on the shaft. Then the pulley wil be placedin position on the spoo the flange 7 eing removed for that purpose, and then the pulley is retained in position by means of the fiange` 7, which is fastened by its screws 8 to the spool. The web ofthe pulley will be cored out to form the receptacle 10, which extends in a continuous circuit around the pulley and communicates, through the inside slot 11, with the bore of the pulley. The lubricating-oil is deposited in this receptacle 10, being introduced through the hole 12, and
l the receptacle filled until it reaches the bearing line or joint between the bore of the pulle and the lower face of the spool. To fill 1t above that line would cause the oil to leak out through the joint. After the receptacle 10 has received lts uota of oil the hole is closed by means of t e screw-threaded plug, as shown.
Y The rotation of the pulley causes-the oil to be distributed by centrifugal action over the entire outer wall of the receptacle 10, whence it runs when the pulley stops, as at noon, night, or at other tlmes in the course of busi.- ness, down upon the spool and is carried thence into the bearing-surfaces between the sipool and pulley.- In order to facilitate the lstribution" of thelubricant to -the remote corners or friction-surfaces of the bearings, the oil-glands 13 are provided. These will preferably be drilled in from the corners of the web of the ulley.
In the modiiicationshown in Fi 2 lthe spool 14 is devoid of flanges; but t e spool itself is secured by set-screws (shown by dotted lines 15) in the manner described for spool 4. The pulley 16 is split on the line 17 17, which enab es the two parts to be molded and cast without coring and also enables the pulley and spool to be assembled before the two parts of the pulley are fastened together. This latter is accomplished by means of the screws 18. Radiating from the splool 14 are the tubes 19, which are open at t eir outer ends and are referably expanded there to gather the oil co lecting at the inside rim by centrifu al action and directs the oil inwardly towar the spool, u lon the face of which it is discharged throug suitable erforations 20 at the base of the tubes. T ese erforations preferably have the channels 21, eading off laterally to carry the oil intothe joints or bearing-surfaces.
Other means may be employed to insure a deposit of oil upon the spool-such, for exam le, as a disk of wicking which would absor the oil at the outer wall of the annular receptacle and conduct it by capillary attractionto the spool.
Havin thus fully described my invention, what I c aim as new, and wish to secure by Letters Patent of theUnited States, is
1. A shaft, a spool fixed thereon, a pulle mounted loosely on the spool, means for holcf ing it in position on said spool, said pulley having an annular oil-receptacle around its hub and an annular slot from the receptacle into the hub-bore intermediate of the hub ends and auxiliary conduits from the receptacle to the outer ends of the said hub-bore.
IOO
2, A shaft, a spool fixed thereon, a pulley mounted loosely on the spool said pulley having an annular oil-receptacle around its hub and an annular slot from the receptacle into the hub-bore and tubes seated in said spool and extending radially therefrom into the oil-receptacle through the said annular slot said tubes having perforations through their Walls at their bases.
3. A shaft7 a spool fixed thereon, a pulley mounted loosely on the spool said pulley having an annular oil-receptacle around its hub and an annular slot from the receptacle into the hub-bore and tubes seated in the spool and extending radially therefrom into the 15 oil-receptacle through said annular slot said tubes having perforations at their bases and said spools having channels extending from said perforations.
In Witness whereof I have hereunto set my 2o hand and seal, at Indianapolis, Indiana, this 11th day of August, A. D. 1904.
CHARLES B. MCKOWN.
