Specification of Letters Patent.
Patented July 5, 1910.
Original application led February 15, 1908, Serial N o. 416,089. Divided and this application iled August To all whom it may concern:
Be it known that L'ANDREW S. GUSTAF- son, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Car-W'heel, of which the following is a specification.
This invention relates to car wheels and is more particularly a division of an applicat-ion filed by me on February 15, 1908, said application having issued as Patent No. 898,463, dated September 15, 1908.
The object of the invention is to improve and simplify the construction of the wheel and to render the same more eiiicient in operation by the provision of diverging oil ducts which communicate with the oil receiving reservoir and through which lubricant is automatically fed to the axle.
A further object is to make provision for the perfect lubrication of the parts subjected to friction and wear when the lubricant in the reservoir falls below the line of the journal bore, provision also being made for using the remaining lubricant over and over again.
A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efciency.
Further objects and advantages will apear in the following description, it being understood that various changes in form, proportions and minor details of construe tion may be resorted to within the scope of the appended claims.
In the accompanying drawings forming a part of this specification: Figure 1 is an elevation of a car wheel constructed in accordance with my invention. Fig. 2 is a vertical sectional view taken on the line a-a of Fig. 1. Fig. 3 is a vertical sectional view taken on the line b-ZJ of Fig. 2. Fig. 4 is a sectional view taken on the line c-c of Fig. 1. Fig. 5 is a detail sectional View taken on the line cZ-(Z of Fig. 2.
Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.
The improved car wheel formingthe subject matter of the present invention comprises a hub 5 having a plurality of spokes 6 radiating therefrom and preferably formed Serial No. 447,844.
integral with the Vrim 7 of the wheel, as shown. The hub 5 is provided with a circumferential row of transverse cores or ribs 8 defining intermediate oil passages 9 which surround the journal bore 10 and communicate with an oil receiving reservoir 11, the latter beingv disposed at the front end of the wheel and in communication with the bore of the axle box, as shown. The front wall of the reservoir 11 is bowed outwardly and provided with oppositely disposed extensions 12 in which are threaded tubular valve casings 13, the exterior walls of which are preferably tapered and threaded, as shown, for engagement with correspondingly threaded openings in the extensions 12, thereby to assist in preventing the escape of oil or other lubricant. The casings 13 extend transversely across the adjacent oil receiving compartments 14 and are provided with openings or orifices 15 through which oil or other lubricant may be introduced into the compartments 14 when it is desired to refill or replenish the chamber 11.
Slidably mounted in each tubular member 13 is a valve 16 which forms a closure for the adjacent opening 15 and is normally held in closed position by a coiled spring 17 interposed between the valve and the adjacent wall of the chamber 14.
Communicating with the chambers 14 is a circumferential groove 18 which also communicates with the oil passages 9 and through which oil is fed from the chamber 14 to the reservoir 11.
Journaled in the bore 10 is an axle 19 having its free end provided with an annular groove 2O which registers with correspending seating grooves or recesses 21 formed in the hub of the wheel for the reception of locking devices 22, the latter being loosely mounted in the seating grooves and preferably in the form of hardened steel pins. The seating grooves or recesses 21 intersect the adjacent ribs 8 and are of greater length than the pins 22 so as to permit free sliding movement of the pins within the grooves thereby to reduce friction between the parts. vOne end of each seating groove opens through the adjacent side wall of the reservoir 11 and is provided with interior threads 23 which engage correspond ing threads on suitable plugs 24, which latter form closures for the seatino` grooves 21 and also receive the impact of the pins 22 -as the latter move back and forth in said grooves. rlhe threaded walls of the seating grooves are preferably inclined or tapered, as are likewise the-wallsof--the'plugs 24E-in order to insure atight fit between the parts and thus prevent the escape of the lubricant.
Attention is here called to the fact that the pins22 byengagement with thewalls 20.1and 21 serve to lock the axle19 in position onthehubof the wheel, while at the same time4 permitting free rotation of one of--said members with relation to the other. It will alsobenoted that the impact of one endofeach pin is lreceived by the plug whi-lethe impact of the opposite end` of the pin is received by the adjacent interior wall ofthehub 5.
The rear end ofthe hub 5 is formedwith an. extension 25 having an annular recesss26 formed therein which communicates with thebore of the hubv and in which is .seated a flexible washer 27 preferably formed of felt and whichserves to preventleakage of oil when the wheel is at rest.
AThe interior walls of thefjournal bore 10 are formed with diverging oil ducts 28 which communicate with the adjacent seating grooves A21 and. extend in the direction ofthe packing v27" so that asthe wheel rotates the oil fromthereservoir will be fed through one of the ducts 28 longitudinally of the wheel and thence back throughthe adjacent duct 28 and seatinggroove 21 to the reservoir thus thoroughly'lubricatingthe axle and its associated parts.
In order to properlydistribute the lubricant on the ournal bearing, when the oil in the reservoir 11 and passage 9 becomes low, a series of oblique oil ducts or slots 28 are formed in the walls of the journal box 10 and arrangedin spiral form, as shown, said slots or ducts forming a source of communication between the passages 9'and the journal bore so that the oil from the reservoir 11 will be fed to the journal and then How back into the reservoir to be used over again. It will thus be seen that when the Wheel rotates, the lubricant is forced against the outer walls of the oil passages 9 Vfrom whence it drops yby gravity through the slots or ducts 28 onto the journal, the ducts 28 being `so .arranged as to direct the oil back along the journal yinto the reservoir, as before stated.
By making the plugs removable the'latter may be readily detached from the hub so as to permit the removal of thepins 22 when the samebecome worn or otherwise injured from constant use, or when it is desired to remove the wheelfor any cause.
AWhen the oil in the reservoir '11 needsreplenishing a lateral pressure is exerted on the `valve 16` which yexposes the Vorifice 15 so that by introducing the spout of an oil can within the tubular member 13, the oil will enter the chamber 14 and thence flow 'througlrthe annular groove 18 and the several passages 9 to the lreservoir 11, a-:portion of the oil in the reservoir being fed through .the seating grooves 21 and ducts 28 to the 1.
