GEORGE D. FRAUNFELDER, OF EASTON, PENNSYLVANIA, ASSIGNOR TO EAS'ION CAR & CONSTRUCTION COMPANY, OF EASTON,- PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

oAn UNIT.

My invention relates to dump cars in general, and particularly to that class of cars used in connection with quarry Operations. All quarry cars when used for steam shovel "service are subjected to tremendous shocks and strains. The load from the shovel dipper consists of large size stone and is usually discharged while the dipper is suspended high above the car body. Further, this load is very frequently dropped on the side and top edges of the body instead of on the bottom, and in quarry car construction. the car must be sufficiently rigid to prevent its being accidentally dumped or derailed from the force of such blows, either while being loaded or during transportation.

The object of my invention may be briefly summarized as consisting of the construction and combination of parts which will effectually overcome the above-mentioned difliculties common to car construction.

It is to be understood that I do not limit I myself merely to the details of construction as shown, but that the scope of my invention extends to whatever construction may be defined by or included within the terms of the appended claims.

In the drawings: Figure 1 is an end elevation of a dump 10 car embodying my invention;

Figure 2 is a top plan view illustrating one corner thereof;

Figure 3 is a detail sectional view on the line 33 of Figure 2; Figure 4 is a side elevation of my improved dump car, partly broken away; and Figure 5 is a detail view in perspective of one of the hinged members.

My invention, in the. form or embodiment shown in the drawings and briefly described,

comprises a main frame, 10. a car body, 11,

and aligning hinges, 12. The-novel form of'main frame, 10, is constructedin a substantially rectangularform and comprises the side I-beams, 13, and the centrally located channel members, 14, they extending lengthwise of the main frame. The I-beams, and channels, 13 and 14, are connected at 'theireXtreme ends bymeans of the transversely extending channels, 15. To render the main frame very rigidin construction, I securely rivet to the upper edge of the I- beams, 13, a plurality of super-imposed and transversely extending I-beams, 16, as is clearly shown in Figures 2 and 4 of the accom anying drawings.

y improved car'body is provided with a flat bottom portion, 17, and upwardly and outwardly diverging bottom portions, 18, terminating at theirouter edges in right angular bent portions, 19, as is clearly shown in Figure 3. To further reinforce these outer edges or bent portions, 19, I provide angled members, 20, each having one of its sides adjacent to the bent portion, 19, and the other adjacent to one flange of the I- beam 22 and securely riveted to both.

In order to retain the bottoms, 17 and 18, ofthe car body in position, regardless of the heavy shocks to which they are sub-.

jected, I employ a plurality of I-beams, 22, they being extended entirely across and conforming to the contour of the bottom of the body, 11. The I-beams, 22, are suitably riveted to the bottoms, 17 and 18, bymeans of rivets, 23. The angle members, 20, are sufficiently spaced from the bottoms, 18, to permit the side, 21, of the angle, 20, to bear against the lower leg of the I- beam, 22, to which it is securely fastened by means of the rivets, 24.

The ends, 25, of the car body aretsecured inposition by means of rivets and are reenforced at their upper edges by means of the angled strips, 26,- which are also riveted thereto. Corner strips or members, 27, are extended between the angled strips, 26, and

the angled bent portions, 19, and securely riveted thereto.

It will be readily understood with particular reference to Figures 1 and 4 that the I-beams, 16 and 22, are of the same height.

.By means of this novel arrangement, the lower edges of the central portions of the I- beams, 22, rest upon the longitudinally extending members, '13 and 14, whereas the bottom, 17, is firmly seated on the upper faces of the transversely extending I-beams. 16. This construction, it will .be readily seen, affords a very rigid and substantial support for the body and will effectually prevent any twisting, buckling or' straining of the body with respect to the main frame support.

For the purpose of effectually absorbing all unnecessary jars or shocks from the bottom, 17, of the car body, I'provide a plurality of longitudinally extending strips of wood,.29, and a steel plate or super-imposed bottom, 30. as is clearly indicated in Figures 1 and 2. These strips or planks, 29, together with the supplemental bottom, 30, may, of

- ners of the main frame, 10, and relatively movable members, 33, which are riveted to the lower sides of the body, 11.

The brackets, 32, of the hinge, 12, are each preferably cast and consist of a pair of ver tically extending right angular flange members? 35 and 36, and a horizontally disposed flange, 37. Extending upwardly from the flange, 37, area pair of integrally cast end walls or ears, 38, which are connected by means of the side walls, 39, and 40, for the purpose of forming a substantially semicircular recess, 41. Openings, 42, are concentrically disposed through the end walls or ears, 38, for a purpose to e later described. The fian es, 35, 36 and 3, are provided with suitable openings for the pur-' pose of being riveted to the I-beams, 13, and

the channel members, 15. These right angular flanges, 35 and 36', it will be readily seen, serve as corner locking means by reason of their being secured to the adjacent corners of the main frame, 10.

Snugly fitting within each of the semicircular recesses or depressions, 41, is a substantially cylindrical member, 43, which is cast or otherwise formed integrally with a pair of angularly disposed flanges or plates, 44 and 45', and reenforced by a suitable rib, 46. i The included angle between the flanges or plates. 44 and 45, is, of course, identical with the angle of the bottoms, 17 and 18, of the car body, to which the flanges are "suitablggriveted.

y reason of the cylindrical hinge members, 43, fitting into their respective recesses or depressions, 41, the car body is firmly held into,its seated position regardless of the factv that the dump car is fully loaded or empty. All end and side thrusts of the body are, of course, taken up by the cylindrical members 43 of bracket 33 moving against the end wall 38 of bracket 32. Should it be further desired to lock the car body to its supporting frame, I have rovided a pivot pin, 47, for each pair of liinge members, 12, with a slightly tapered nose on its inner end and an eye on its enlarged outer end, for the purpose of connection by means of a chain or the like to the car, the said pin being introduced through the apertures, 42, and a concentric aperture in the member, 43.

There are instances where I have found it desirable to invert or rather reverse the powill not be retained within the semi-circular depression and revent the entering and seating of the cyhndrical portion, 43, within its mating recess, 41.

Rigidly secured upon the outer edge of each side of the car body and in the approximate center thereof, is a lifting device, 50, as is clearly indicated in Figures and 4. Each of the lifting devices consist of a pair of similarly formed castings or the like, each provided witha pair of right angular flangcs, 51, which are provided with openings for the purpose of riveting to the outer edge of the box girder construction and to the angular members, 21, to carry beams, 22, and in this manner, all pull is on the I-beams, 22, instead of late 18. These castings are further provi ed with a pair of aligning hub portions, which are provided with central openings for the purpose of receiving a liftmg arm or rod, 52. The angularly formed flanges, 51, of the lifting devices being riveted to the outer and under sides of the box girder construction provide a very rigid means for tilting the body of the car.

It is to be understood, of course, that although it has been found from actual tests under the most severe working conditions that an all-steel car built in accordance with my invention, is highly efficient, economical and practical, yet beams of wood may be substituted in lace of the I-beam floor supports, 16, if I so esire.

When it is desired to dump my improved car, one of the sets of aligning pivot pins, 47, are removed from the apertures, 42,which had been inserted through the concentric opening in each of members, 43, for locking the car body to the supporting frame.

A' hoist is then attached to the rod 52 of the lifting device 50, located on that side of the car to be raised, that is, adjacent the disconnected hinge 12. I claim:
