Application August 13, 1934, Serial No. 739,602

4 Claims.

, My invention relates to improvements in ore cars, such as are employed in connection with mines, quarries and the like and relates particularly to dumping means in relation with said cars.

The I principal object of the invention is the production of a car capable of being dumped in such manner as to permit the load being discharged smoothly and evenly and without bulging or distending the sides of the car, the load being free to move without any binding effect while be ing readily timed in its discharge, and this invention is primarily an improvement over my former Patent No. 745,113 issued in the United States Patent Oflice November 24, 1903, and the principal object of the present invention is to provide a greater clearance at the upper front portion of the car body when dumping the ore so that even if the body is bulged'intermediate its ends the front portion will spread sufiiciently to give clear ance for the ore after such bulged condition.

Another object of the invention is to provide greater flexibility to the upper front portion of the car body and means in the door for permitting such flexibility and spreading movement.

Another object of the invention is to provide a structure of this class which provides substantial support intermediate the ends of the body to prevent too much spreading but provides great clearance at the extreme front end particularly at the upper side thereof.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as'willbe hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application, in which:

Figure 1 is a top or plan View or my ore car body complete; Fig. 2 is a side elevational View of the ore car complete showing the car body and door in operative dumping position by dash lines; Fig. 3 is a transverse sectional View shown through 33 of Fig; 1; Fig. 4 is an enlarged detail side elevational View of the front upper corner of the ore car in its dumping position showing the door and its relation thereto, and Fig. 5 is a sectional view along one side through li5 of Fig. 4.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

In the ore mining art it is common to use cars having their bodies pivotally mounted upon the truck and hinged in such manner as to be capable of being dumped in almost any direction from the truck, but inthe use of such cars serious difliculty has arisen through the fact that in discharging the load-the ore binds against the sides of the car body and causes the same to expand. Of course the degree of expansion at each dis charge maybe comparatively small but in the course of a few months the car sides become bulged-quite perceptibly sometimes even to a number of inches making the dumping more difficult and slow besides shortening the life of the car. To overcome this difficulty and to facilitate the discharge of ore from an ore car applicant provides a car employing as seen in the f,

accompanyin drawing a common form of truck 9 upon which is mounted a turntable 2. A car body 3 is secured to said turntable by means of suitable hinges d, whereby said body is capable of being pivoted in a horizontal plane and pivoted vertically in. any desired direction. Aswill be observed from a careful examination or Fig-, l oi the drawing, the body 3 is wider at its discharge or front end than at its rear end and the same is wider at the base of the rear end than at the top thereof, whereby said body flares gradually 7 from the rear end forwardly and downwardly thus facilitating the discharge of ore. The contained ore while being discharged constantly moves into portions or" the car body of greater area than that previously occupied.

As disclosed particularly in Figs. 1 and 2, the forward end of the car body is open and a door 5 is arranged for normally closing the same, said doc-r being formed with side webs 6 extendingalong the sides of the body 3 enclosing the same and being pivoted thereto at l. Fixed to the table 2 and extending laterally therefrom are suitable arms or brackets 8 provided with eyes 9 to which are pivotally connected links ll]. Said links extend upwardly and pivotally engage the webs t at the pivot point M. It will be noted that the pivot point it is spaced somewhat forwardly of the pivot l whereby the door 5 will be retained in a vertical plane regardless of the position of the body 3. Any suitable latch device 5?. may be employed for normally locking the body 3 in its horizontal position. It will be here noted that in addition to the particular wedge shape of the body as will permit the ready discharge of contained material even though the walls of said body be slightly bulged or distended, applicant has provided a reinforcing member 3a which extends across the front of the body 3 at the upper edge and backwardly considerably past the pivot point i for reinforcing the upper edge of said body. However, this reinforcing does not extend to the front end of the body 3 on the opposite sides, thus providing greater clearance between the upper front corners of the body member and the door webs 6, thus permitting these upper front sides 30 to flex outwardly to the Web members 6 of the door 5 when dumping.

Applicant has also provided outwardly bulged portions Ed in the web portions 5 which are provided with inclined or wedge portions 61) which merge into the main portions 6, thus providing for further expansion of the upper front corners do when in dumping position, as shown best in Fig. 4 of the drawing, to provide further clearance and ready exit of the ore from the car body.

The operation of the car is as follows: It is dumped by first tripping the latch l2 and then tilting the body 3 upon its hinges 4. By this movement of the body the door 5 is caused to swing upon its pivot i, the links iii moving with the longitudinal movement of the body 3 but limiting the door 5 against vertical movement, whereby said door is caused to assume a position above the discharge end of the car body. The tilting of the car body 3 may be done gradually and the door 5 will open in timed relation to the movement of the car body whereby the load may be discharged at any desired speed and owing to the particular shape of the car body and the freedom for flexing of the front upper corners of said body the ore will have free movement from said body and binding will be reduced to a minimum although the body may be considerably bulged and there will be little danger of binding and injuring the walls of the car body.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a mechanism of the class described, the combination with a support of a receptacle pivotally mounted thereon and formed with a discharge opening, the walls of said receptacle flaring from all points to the point of discharge, the front end of said receptacle being open, a door arranged to close said discharge opening provided with side webs adapted to extend over the sides of the front portion of said receptacle and pivotally connected intermediate the ends of said body at the upper edge, reinforcing along the upper edge of said receptacle extending forwardly of the pivotal support of said door a short distance only and around the back portion of the receptacle, and bulged portions in the webs of said door arranged to permit outward movement of the front upper corners of said receptacle when in dumping position.

2. In a mechanism of the class described, the combination with a support of a receptacle pivotally mounted thereon and formed with a discharge opening, the walls of said receptacle flaring from all points to the point of discharge, the front end of said receptacle being open, a door arranged to close said discharge opening provided with side webs adapted to extend over the sides of the front portion of said receptacle and pivotally connected intermediate the ends of said body at the upper edge, reinforcing along the upper edge of said receptacle extending forwardly of the pivotal support of said door a short distance only and around the back portion of the receptacle, and bulged portions in the webs of said door arranged to permit outward movement of the front upper corners of said receptacle when in dumping position, said bulged portions in said webs provided with inclined portions merging into the main portions of said webs.

3. In a mechanism of the class described, the combination with a tilting body portion formed with a discharge opening, of a pivot d door closing said opening, webs carried by said door enclosing a portion of said body, means engaging said webs for lifting said door from its closed position, said webs provided with bulged portions adjacent the upper front corners of said body portion when in dumping position for relieving the upper front corners of said body and permitting spreading thereof.

4. In a mechanism of the class described, the combination with a tilting body portion formed with a discharge opening, of a pivoted door closing said opening, webs carried by said door en-- closing a portion of said body, said webs pro vided with bulged portions adjacent the upper front corners of said body portion when in dumping position for relieving the upper front corners of said body and permitting spreading thereof, and means for swinging said webs and door upon their pivots relative to the movement of said body.
