CAR.

Application filed December 13, 1921. SerialNo. 522,080.

T0 all whom i may concern.'

Be it known that I, GLENN E. EDMUNDS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Cars, of which the following is a specification, ,reference being had therein to the accompanying drawing.

This invention relates to improvements in cars, particularly'cars of the class used in and around industrial plants, and in coal mines for transporting the coal. rlihe object is to provide a car which will embody all of the advantageousfeatures of the cars of the better class now in use, and will have the partsso `constructed and arrangedas to provide a maximum of cubical capacity without increasing the overall height and width of the present cars now in use. As is well known, these cars, especially in coal mines, must travel in rooms or entries where the roof of the mine is comparatively low; and this condition prohibits increasing the height of the cars above a certain Xed limit. n p

Another object of the invention'is to provide a novel mounting for the wheels whereby through axles can be dispensed with, and the wheels of each pair, transversely, will be independent of each other in respect to their revolutions and slippages.

Fig. 1 is a side elevation of a car embodying my improvements.

Fig. 2A is an end view of the same.

Fig. 3 is a bottom view of the same.

Fig. 4 is an end elevation showing the end opposite that shown in Fig. 2.

Figs. 5 and 6 are side elevations of the inner and outer frame parts, respectively, in which the wheels are mounted.

' Figs. 7 and 8 show one of the wheels and its details of construction.

Fig. 9 shows one of the short axles` upon Fi and F.

The bottom of the body 2 has the two metallic side sills 1, 1, preferably channel. beams, and the cud bumper castings 2, 2

each having the side portions 3, 3, each of the latter overlapping one end of a side sill and being rigidly riveted or bolted thereto at 4, 4. The Hoor of the car is formed of wooden planks 5, 5 of suitable thickness, riveted or bolted to the bumper castings 2, 2 at 6, 6 and to the side sills at 7, 7-and 8, 8. l

The sides of the body portion of the car comprise the uprights 9, 9, there being one of` these on each side ai; each end of the car and one on each side of the middle portion thereof. As shown these uprights are each formed to have the lower vertical portion 9a,- the outwardly and upwardly-extending portion 9", and the upper vertical portion 9c. The lower portion 9 of each upright; is riveted or bolted to onel of the side sills; and the side boards 10, 10 of the body are secured to the upper portions 9, 9c of the uprights by means of rivets or bolts 11, 11, the uprights being provided with apertured ears 12, 12 through which the rivets or bolts pass.

The end E of the car is constructed to serve as a door swingable outward around the upper hinge bar 13 which is mounted in vertical extensions of the u rights 9 at one end` ofthe car.` The eind comprises the planks 14, 14 securely fastened together by the metal straps 15, the latter terminating in eyes 16, through which the hinge bar 18 passes that permits the vertical swinging movement of the door. At 17, 17 the wooden portions ofthe door are cut to conforln to the sides of the car to insure a snug fitI when the door is in closed position. To retain theI door in such position a latch, hereinafter described, is provided.

The wheeled truck B of the car comprises .the cross girts 18 and 19, the short sill- like elements 20 and 21, the axles 22 and the wheels 23.

As shown in Figs. 5, 6 and 1() thesills 20 and 21 are similar in design, one, however, being longer than the other for a purpose to Ibe described. Rach is formed, preferably, of castI metal and has the web portion 24 with the strengthening edge flanges 25. Each of the castings is formed with a recess 22EL near each end thereof to receive the end of an axle, and the strengthening web 25 is drilled at each side of each of the recesses 22. as at 2G. to ref-cire the pins or bolts that. hohl the axles in position.

lill) metallic fastening devices.

An axle is shown detached in Fig. 9, it preferably being a hollow tube with plugs or closures 27 fitted in the ends, the interior of the axle being thus made a lubricant reservoir. Diametrically opposite apertures 27a are drilled in the axle tube at each end to receive the bolt-s passing through the apertures 526 in the flanges Q5 of the truck castings 20. 21, which hold the axle rigidly in place when the parts are assembled. A small aperture 28 is formed in each axle tube to furnish lubricant to its exterior surface. 23, 23 are wheels which may be. of any preferred construction. As shown. each com prises a hub 30, spokes 31, tread 32 and rail flange 3?). To reduce rolling friction, as much as possible, roller bearings 34, suitably retained in place, are provided, they being interposed between the interior wall of the hub and the axle 2Q.

The parts which carry the wheels at one side of the car are connected to the parts that carry the. wheels on the other side by the frame girts 18 and 19. These are of channel metal and have their flanges turned downward. The longer girt 19 extends through apertures 35 in the inner sill bars 21, each of the latter being formed with a lug or boss 35 to firmly ',t between the flanges of the girt, the latter being secured by bolts at 37. It is also fitted at its ends in the outer sills 20, which have apertures 36, lugs 36 and bolts 37a to hold it to thesills.

.The cross girt-s 18 are shorter than that at 19; they, at their ends, being fitted in cavities 22h-in the ends ofthe longer sill castings 21, the metal. here being formed with lugs 22 that lit between the flanges of the cross girts 18 to which they are rigidly secured. The girts 18 and .19 are provided with apertures at suitable points along their central parts to receive the bolts which fasten the body and truck frame together.

It will be seen from the above that the car, as an entirety, comprises two separable elements. each complete within itself; 'one being the truck comprising the metallic cross girts and sills 20, 21 rigidly joined together with the axles and wheels; and the other being the body comprising the parts at the sides and ends. together with their It will also be observed that the metallic truck element may be regarded as composed of a central part, and the wheel carrying frames at the extremities, rigid with the central part.

coupler 40 is secured to the central part of the car at each end and is bolted to the bumper casting at points within the body portion of the car, but has its pin receiving portion extending through the end walls. as shown. Each of these coup-1ers comprises the strap which is secured atits inner end tothe floor of the. car and to the in wardly projecting tongue 46 of the bumper casting by means of a bolt 47. This strap extends outward and upward for a short distance, and has a horizontal portion 48 projecting to a point near the outer edge of they bumper casting. It is apertured at 49 Y to receive and holdl the lower end of the coupling pin 50 when it is inserted.

The central portion of the bottom of the end gate` E is cut away to permit it to swing past the coupling strap 45. There is a latch 52 pivoted at one end 53 to the door, having its free end held in a loop` in a strap 54. This latch, in its lowermost position is limited by the strap 54, slides along the upper surface lof the coupler element 45 until it reaches a boss 55 formed thereon and having a sloping outer surface. and a vertical inner surface. iVhen the latch reaches the boss it is lifted by the sloping surface, passes over the top of the-boss andthen drops to its locked position behind the vertical surface. To release the door the latch 52 is 'lifted around the pivot 53 and the door may then be swung outward to dump the contents of the car. At 56 the latch is bent outward'to provide a handlefor convenient manipulation.

To further strengthen the sides of the car a U-shaped bracket 60 is bolted to the outerwheel-supporting elements Q0 and to the middle uprights 9 at points near the outer end of the inclined portion 9b. These brackets strengthen, to a great extent, the side walls of the car and relieve the uprights of a great deal of strain which would be placed upon them without suchreinforcement.. It will be noted that the middle uprights 9, together with the straps 60, form arch members which transmit the expanding strains set up by the material in the body to both the outer and inner sill bars 20, 21, thus properly balancing the truck and enabling the sides of the body which are extended out over the wheels to be properly supported by the outer sill bars.

The advantages incident to a car such as I have described will be readily seen. By securing the cross girts 18 and 19 to the castings 20 and 21 at points below the upper edges of the latter I am enabled to materially deepen the body portion of the car without increasing its ever-all height. In all other cars with which I am acquainted the horizontal positions of the cross girts have governed the height of the bottom of the car above the road bed. In some cases the bottom of the car has been relatively lowered by bending the cross girts downward at the sides of the car to permit such lowering, the truck portions remaining unchanged. But this greatly weakened the running gear. I accomplish the same result and at the same time produce a car with greatly increased strength and durability.

I dispense with the parts for separate lll) iaaofra draw-bar construction which have heretofore been necessary, and sustain the draft strain practically entirely by the metallic framework at the base of the car.
