Application flied June 23, 191.3. serial No. 775,370.

Tol all whomfit may concern Be it known thatl, MAGNUS E. STANGE, a citizen ofthesUnited States, residing at St. Paul, in the county of Ramsey and lState of Minnesota, have invented certain new and useful Improvements in Dumping-Cars; and I do ,hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe saine. My invention relates to dumping cars of that `type which are usually arranged to travel on rails andare used inv making ex-v cavations and grading and which are provided withbodies or boxes mounted for late eral, pivotal dumping movements and have side gates arranged to be moved away from the sideslof the car on the discharge side of the tilted body. l

#Generally stated, the invention consists cate like parts throughoutthe several views.

p Referring to the drawings, Figures 1 and 2 are views in end elevation, showing the carl embodying my invention and illustrat.- ing, respectively, the normal and dumping which are arranged to run onl rails 2. The couplers 3, at the ends of the car are secured to or formed as partof end pedestals 4. The c ar body or box at the transversely central lower portions of its ends, is provided with heavy hingebrackets 6 having dependnigA lugs T that are pivotally connected to extreme upper 'portions of the pedestals 3. This car body 5 is formed with open sides that are adapted to be closed by heavy side gates 8. Upright metal posts 9, preferably in the form of angle irons, vare rigidly secured to the edges of thefront and rear ends of the body 5, and to the under frame structure 5a of said body.L i The side gates 8 are pivotally connected to the outer ends of upper and lower supporting bars 10 and 11, respectively. The

upper bars 10 are longer than the lower bars 11 and their inner ends are downwardly curved and pivotally attached to the end brackets 6 yat 12. The pivots 12, by means ofthe brackets 6, are indirectly secured to the ends .of the car, near the bottom thereof and at `points in the immediate vicinity of its transversely central portions. Infact, the said pivots 12 might be coincident and located .at the exacttransverse center of the car. -The inner ends of the relatively short lower bars 11 are connected by supporting links 13- to the inner end portions of the upper bars `10. Thrust vlinks 14, pivotally connect the innerends of the said lower bars 11 to the central portions of the ends of the car body 5 at 15. The said pivots 15 are located above the pivots 12 and are preferably directlypivoted to the metallic straps or eX- tensions 16 of the end brackets 6.

f Gate lifting bars 17 are pivotally connected at their upper ends to intermediate portions of the upper gate supporting bars 10, and their lower ends are adapted to engage portions of the frame of the truck 1. It

Ymaybe here stated that the car above described, inay involve one or more trucks 1, depending .on the length of the car. Guide links 1.9.:'are pivotally connected at their outerfends to the intermediate portionsof the posts 17, and at their inner ends, are pivotally connected .to depending lugs 20 of the end brackets 6.

The car body or box 5, when in its horizontal or normal position shown in Fig 1, and both when loaded and when empty, will be approximately balancedor in a neutral position. It is .normally held against pivotal dumping movements by chains 21, shown as ,attached at theirl upper ends to the sides of the under frame 5a and attached at their lower ends to the sides of the frame of the truck 1. These chains 21 are made 1in sections, tlie upperY sections, as shown, having hooks 22 that are detachably engageable with links of the lower sections.- YVhen it is desired to dump the car body, the sections ofy the chains on .the opposite side from which it is desired to dump, must be un-V with stop plates 18 secured on the side end of the car body from the position shown in Fig. 1 into the position shown in Fig. 2, the gate S on the rising side of the body remains in a closed position, but the gate on the lower side is opened with an accelerated movement produced when the gate tripping bars 17 on the lowered side, engage with the stop plates 18 of the truck. When this engagement between the bars 17 and plates 1S takes place, downward movement of the gate 8 on the lowered side of the car body ceases, and as the pivot 12 on that side continues to lower, the bars 10 operate as levers having a fulcrum on their upper ends of the bars 17, and .thereby produce an upward movement of the said gate. More than this, the pivot 15 moves rapidly toward the right, in respect to Fig. 2, and thereby gives to the lower edge portion of the open gate a rapid Outward swinging movement, so that the said gate is thrown into an oblique position shown in Fig. 2. This movement very greatly increases the rapidity with which the open gate recedes from the open side of the body, and hence, gives a quick and very free dumping action. Furthermore, with Y the arrangement described, all strains due to the weight of the gates and to the pressure of the dirt thereon is transmitted directly to the end brackets 6, and from thence to the subframe structure 5a of the car body. Thus I eliminate an objectionable action which takes place in various other dumping cars of this general character, to-wit, tendency to rack the ends and corner post of the car body, due to pivotal connections directly between the upper portions of the end boards or members, and the gate supporting connections. Obviously, also, a freer and much greater dumping action is produced by my improved gate supporting connections, which move the gates both with an upward and angular outward swinging movement on the dumping side of the car, and thus obtain a very quick and complete opening movement.

IVhat I claim is:

1. In a dumping car, the combination with a supporting truck, and a car body intermediately pivoted thereto for lateral dumping movements, of gates coperating with the sides of said car body, upper and lower bars pivotally connected to said side gates at their outer ends, said upper bars having inner ends pivotally connected to the lower central portions of the ends of said car body, supporting links pivotally connecting the inner ends of said lower bars to the said upper bars, thrust links pivotally connecting the inner ends of said lower bars to the central portion of the car body, and gate lifting bars pivotally connected to one of the said gate supporting bars and engageable with the truck frame, and operative to impart an upper and outer angular swinging movement to the side gate on the lowered side of the car body.

In a dump car, the combination with a car truck and a body intermediately pivoted thereto for lateral dumping movements, said car body having end brackets centrally secured to the lower portions of the ends thereof, side gates for normally closing the sides of said car body, upper bars pivotally connected at their outer ends to the upper portions of the ends of said side gates and having their inner ends downturned and pivotally connected to the end brackets of said car body, lower links pivotally connected at their outer ends to the lower end portions of said side gates, links connecting the inner ends of said lower bars to the intermediate portions of said upper bars, thrust links pivotally connected to the inner ends of said lower bars and to the central portions of the ends of said car body.
