:TPEGIFIGATION forming part of Letters Patent No. 655,163, dated. J 31, 19b0.

' Application fileelbecemter- 13,1899. Serial No. 746,731. on moaia To aZZ whom it may concern.-

Be it known that I, PHILLIP F. POORBAUGH, a citizen of the United States of America, re= siding at Allegheny, in the' county of Allegheny and State of Pennsylvania hav'e in vented certain new and useful Improvements in Steel-Oar Construction, of which the following is a specification,- reference beinghad therein to the accompanying drawings.

My invention relates to certainnew and useful improvements in steel-car construction, and more particularly to that class known as pit-cars.

One of the objects of my invention is to lessen the weight of material used in the construction of cars of this kind, as Well as in,- crease the durability of the same, lessening the length of the car without decreasing its carrying capacity, and thereby overcoming such objectionable features heretofore in the wooden and heavy steel pit-cars now in use.

A further object of my invention lies in my improved hollow axle used in the construction of the car and adapted to receive a stub upon which the wheel is mounted, the stub being shrunk into the end of. the axle, securely holding the same in position. By this arrangement the following advantages are obtained: The axle will wear better. It will be lighter and stronger, andits use in the mannerset forth materially lessens the weight of the car, and also by the use of the stub the same when worn can be easily replaced within the axle without entirely or partly destroying the same.

A further object of my'invention lies in my improved end-gate or door used in the construction of the car and which is so arranged as to be lifted from the end of the'car when the same is tilted and when so lifted being entirely out of the way of the moving coal. This prevents the pounding or breaking of the end-gate to'pieces, as is usually the case in pit-cars now in use. Furthermore, I provide the car with means for securely locking the end-gate or door thereto when the car is not tilted, the importance of which can be very readily seen, particularly in the use of such cars for shaft-mines.

A further object of my invention lies in constructing a car with a draw-bar on the underneath face of the bottom, the movement thereof not being hampered by the coal re'stf ing upon the same, obtaining by such construction a decreased draft when a train of cars are rounding'a curve.

Afurther object of myinvention lies in constructinga car in such a manner as to bring thebody thereof closer to the rails and at the same time provide a car with supportingwheels of larger diameter and a heavier flange. This is obtained by a bearing-sleeve for the axle arranged in the manner herein described.

My invention consists in the novel construc tion, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings,- forming a part of this specificatiomand Where' in like numerals of reference indicate corresponding parts throughout thesev'eral views, in which- Figure .l is a perspective viewof my improved car when set up. i Fig. 2 is a crosssectional view thereof, partly broken away,

through one of the axles. Fig. 3 is an end view, partlybroken away, the wheel being in section, showing the hub of the same of a greater diameter to receive roller-bearings when mounted on the stub. Fig. 4 is a vertical sectional View, the wheel partly broken away, showing the arrangement of the rollerbearings and a self-oiling means. Fig.6 is a side view of the bearing-sleeve. Fig'. 6 is a' perspective view of the drawbar partly broken away.

. Referring to the drawings by referencenum'erals, 1 indicates the bottom of the car, which is substantially rectangular and upon which is mounted a vertical section 2, forming the lower part of the sides. Mounted upon the sections 2 is the intermediate section 3 of the sides, these intermediate sections flaring outwardly or arranged at an inclination, as shown, and are adapted to support the top vertical section 4.

Y 5 indicates the front end of the car and is arranged between the sides, as shown, and supported on the bottom. This front end is constructed of a shape formed by the lower two and intermediate flaring or inclined section 3, so that the end 5 will fit neatly between the sides formed by the sections. The

and top are formed of suitable also secured togetherby the T brace-irons 7 8, the brace 7 arranged centrally of the outer face of the car and the brace ,8 at the rear end of the sides. These brace-irons, as well asthe brace-iron 6, are securedto the car by any desirablefastening means. 9 indicates my improved end-gate or door for the car and is of such shape as formed 1 by the rear edges of the sections forming the sides and rests at its lower end upon the bottom 1, which projects for that purpose. The end-gate or door 9 is provided with a pair of strengthening studs or braces 10 11, suitably secured to the outer face thereof and having ismounted the wheel 29 and or end-gate 9.

arranged between the same a hook-rod '12, the upperend thereof being formed in a curvilinear mannerand projecting above the door The lower portion of the outer face of the end-gate or door 9 has suitably secured thereto a transversely-extending fasten-ing-bar13, projecting outwardly on each side thereof, and which is adapted to engage the -Lshapedirons 14, one of which is secured-to the lower rear corner of the sections 2 and projects slightly therefrom, so thatthe upwardly-extending end of the iron 14 will form a means for retaining the end-gate or door in a closed position-that is, against the rear end of the car. The end-gate or door 9 is pivotallyconnected to the sides of the car by means of the hanger-rods 15 16, one edge of which is bent at an angle and secured to the end-gate or door, as at 17, and the oppositev end pivotally connected, as at'18, to the keeper 19, secured to each side of the section 3 of- .the sides. V indicates an angle-iron secured to the bottom 1, as shown, and supports a draw-bar 21,:which is suitably secured therein, as well as; supporting the projecting irons 22 for buffers 23- 24. The draw-bar 21 is formedin three sections, the central section being secured to the bottom of the car and the end sections swivel] y connected to the central secfi OD My improved axles 25 for the car are con structed in a hollow manner, as shown, and arranged inclose relation to the underneath face of the bottom 1. Each end of the axles 25 is supported in a bearing-sleeve 26, secured to each side of the underneath face of the bottom, as at 27.

28 indicates a solid-metal stub upon which retained in position: thereon by means of a washer 30 and cotter-pin -31. The stub 28 is of a slightlygreater diameter th an the opening in the axle- 25 and is shrunk within the samefor the pur pose of securely holding the stub in position. Toprevent a lateral movement of the stub and axle in either direction, I provide the openingin the bearing-sleeve of two different diameters, formingan offset or shoulder 32, against which the ends of the hollow axle abut, so that when the same is in position it is fixed. In case it is desirable to use'rollerthe wheel is made of a greater diameter than the stub 28, so that the bearings can be placed between the stub and hub, as will be seen in Fig. 4. These bearings are retained in position by means of the washer 31 on one side and the outer face of the bearing-sleeve 26 on the opposite side.

age-chambers for the lubricant. v p

34 indicates a brake-rodcarrying a brakeshoe 35, which operates between the wheels 29 and against the tread of the same, The rod 34 is pivotally secured at one end'to the vided with a suitable handle 3 v 38 denotes a supporting-rack for the rod and permitsof the adjusting of the'brake-shoe in relation to the tread of the whee-l It is thought that the advantagesfroin the use of the'hollow axle and stub, together with means for preventing the lateral movement of the axle, can be readily understood from the foregoing description. E

In operating the end-gate o-r door'ofthe car theend of the hook 12 is engaged by a suitable bar or rod. The car is then tilted. As the car is tilting, the end-gate or door will be lifted free from the same in a vertical manner until the coal is discharged therefrom and the car righted'. I r

By forming thesidesof the carin: themanner shown the length of the car can be lessened without decreasing its carrying capacity.

It is thought that the 'manyadvanta'g'es of my improved construction relativeto' cheap ness, durability, and strength can lie-readily understood from the foregoingdescription, i taken in connection with the accompanying drawings, and it will be notedthat various changes may be made in the detailsof 'construction without departing from the general spirit of my invention. I

Having thus fully describe'd myinvention, what I claim as new, and d 'esire to secure by Letters Patent, is
