BENNETT DOOR HANGER FOR BOX CARS OR THE LIKE Filed June 1, 1932 gww/Mm Patented Oct. 10, 1933 UNITED STATES PATENT oFFiCE DOOR HANGER FOR ox'cARs on THE LIKE Deeny Morris Bennett, llva ycross, Ga. I h ApplicationJune 1, 1932. Serial No. 614,784 H 4 cam. (cue-9'7) This invention relates to improvements in hangers for doors, particularly the doors of box cars and relates especially to Wheeled hangers.

The primary object of the present invention is to provide a hanger having a novel means of mounting a supporting wheel which facilitates the rapid replacement thereof when necessary. Another object of the invention is to provide a door hanger having a supporting roller mounted upon a pivot pin which pin is of a character to be turned to present a new wear sur-, face after one side thereof has become worn to such an extent that the ready operation of the door supported by the hanger is affected.

A still further object of the invention is to provide a door hanger having a plate portion which is attached to the door and a roller carrying portion which is detachably connected with the plate and which can be readily removed from the platewhen repair or. replace.- ment of the rollers or their; supporting trunnions is necessary, without removing the entire hanger from the door.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modificationsmark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:-

Figure 1 is a view in elevation of the inner side of the hanger embodying the present invention; I v

Figure 2 is a vertical sectional view through the hanger and associate door parts to which the same is shown'attached;

Figure 3 is a sectional view taken on'the line 3-3 of Figure 1; I

' Figure 4 is a view in edge elevation of a form of the hanger designed for. use upon the bottom of a door. Referring now more particularly to the drawing wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 findicatesa portion of a door structure to which the present hanger is shown attached, a trackw'ay in the form of ahaving a flange uponwhich the wheels of the M hanger may run.

The hanger embodying the present invention is indicated as a whole by the numeral 3 and as shown compriseslthe plate portion 4 having a re duced top extension 5 which is oiT-set from the plane of the plate and is of slightly increased thickness, as illustrated. This off-set top portion has a dove-tail groove 6 formed in and transversely of this inner face and the top portionof the plate 4 has a recessed portion 7 transversely of its upper face in which is mounted one side of an angle guard which is indicated generally by the numeral, 8. This guard 8 hasthe two spaced parallel side portions 9 and 10 and the right angularly disposed intermediateportion '11 connecting them} which intermediate portion is horizontally positioned when the hanger is attached to the door body 1. Theportion 11 of the angle guard positions upon the topedge of the door, as illustrated.

Disposed against the innerface of the head portion 5 of thehanger is the elongated flat head block 12, the ends of which extend beyond the side edges of the portion 5. The face 01' the head block 12 which abuts the portion 5' of the hanger carries a cleat 13, the longitudinal edges of which are beveled or under-cut so that the cleat may be inserted into the dove-tail slot 6.to efiect the securing connectionof the head block with the upper part .of the plate.

Each end of the head bl'o'ck12 is bifurcated to form the longitudinally extending slot 14 and the portions at each side of the slot are cut away from the bottom edges thereof to form the downwardly opening notches .15.

These notches are'of polygonal outline, being preferably, rectangular.

Positioned in each slot 14 is a wheel 16 which isiprovided with a central aperture 17 through which extends the round axle 18. A portion of each end of the ame 18 is of the same polygonal outline as the notches 15, as indicated at 19fand in the present case these ends or trunnion por} tions of the axles are square and designed to snuglyfit in the notches 15 when the wheelsld are in place. The head block 12 has a transverse threaded passage 20 therethrough and this passage at'the inner face of the block is counter-bored as at 21, and through thispassage is passed a bolt 22," the head of the bolt positioning against the outer side of the ,block, while .the shank engages the threads in the bore, thus securing the block against displacement. o

From the foregoing description it will be readily. apparent that in the assembly of the present hanger the block isalttached to the upper portion of the plate after the axles 18 have been placed in the wheels and the wheels inserted into their Since the notches 15 have theiriopen sides di-,

rected downwardly it will be readily apparent that the weight of the door will hold the axles firmly in place and it willalso be readily apparent that after the hangers have been in use and means for securing the block to a door body and the axles become worn upon the under side, the head block maybe removed and the axles taken 'out and given a quarter turn so as to bring Y a new or unworn surface into position'for use. This operation'may be continued until the axle has been turned three times after its initial installation. 'It will thus be apparent that witha hanger of this character the wheel supporting axles may be used {or a"considerably longer period than'in hangers of'other types and it will also be readily apparent thatthe changing of the'axles or replacement of theiwheels maybe accomplished easily and quickly and without the thereof.

i The channel portion 26 01 the bracket 24 has the inner face of its vertical side 28'provided with'a dove-tailgroove 29 in which is slidably engaged the cleat 30 which iscarried by'a roller block 31.

This roller block, 31' isslottedj at its ends like the block 12 of thevtophanger as indicated at 32 and in each of these slots is mounted a roller 33 .upon an axle 34. The ends of this axle 34 are of polygonal cross sectionahdesign like the axles 18, and these engage in suitable notches formed in the bottom edges ofthe portions of the block31'which border the slots 32; As will, of course, be readily apparent the axles '34 ca'n only be detached from the roller block 31by being moved downwardly and since the brackets are placed in such a manner that the rollers rest upon an underlying track 35, theweight of the 'door maintains the rollers and the axles in place;

The block 31Wis further secured tdtIiebracket portion 26 of the hanger bya bolt 36 which passes therethrough andthrough the vertical part 28 of the hanger, in substantially the same carriers therefor may be easilyandquickly removed from place for.repla;cement or repair without having to. detach the entire bracket from the door and as has been previously explained The holding claimed is ,tudinal edge in. shoulder;

the axles may be readily shifted or turned after becoming worn at one point, to arrange a new portion in position to take up the wear and in thisrnanner the life of the entire hanger will be greatly prolonged.
