Application filed August 25, 1916. Serial No. 116,881.

To all whom it may concern:

Be it known that I, JAMES H. BAKER, a citizen of the United States, residing at Fairfield, in the county of Wayne and State of Illinois, have invented new and useful Improvements in Automatic Car-Dumping Appliances, of which the following is a specificatio I his invention comprehends the provision of an automatic car dumping appliance which is applicable to new and old cars Without any alteration of either, the invention providing means whereby the hinged bottom of the car can beautomatically released to assume a discharge position, and subsequently returned a-utomaticallyto its normal or closed the car.

The nature and tion will be better understood when the following description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification like numerals of reference indicate similar parts in the several views and wherein Figure l is a longitudinal sectional view throug' a car showing the hinged bottom sections in their normal or closed position.

ig. 2 is a. similar view showingrthe bottom sections in discharge position. Fig. 3 is a vertical transverse sectional view taken on line 33 of Fig. 1. Fig. 4 is a plan view of the track showing the trip and return members.

Referring to the drawings in detail A indicates the tracks over which the car indi cated' generally at B is adapted to travel, the latter being provided with a sectional bottom, wherein the sections C are hingedly mounted. Each section has its free edge resting on a transverse bar 10, and Which bar is supported by the lower extremities of the links 11 which are arranged at opposite sides of the car. As shown the hinged sections of the bottom of the car have their free edges arranged adjacent each other, thus isposing the links 11 in pairs at each side of the. car. Each pair of links 11 converge toward their upper extremities and are connected together by means of a transverse bar 13 whose length is'greater than the width of the car so that the opposite extremities of the bar 13 project an appreciable'distance positlon during transit of a advantages of the invenbeyond the sides cally disposed elongated'slots 14.

or each on the si pair of links 11 there is bar 13 with a view, of holding the bottom sections 0 normally in their closed position. I In thls position of parts the. transverse bar l3 is at the uppermost end of clearly illustrated in Fig. 1.

ridging the ties along the track, and disposed at opposite sides of the tracks A' are substantially archshaped trip members 17 whichare disposed in the path of the lower extremities of the arms 15 so that when each arm 15 is brought into engagement with one of the trip members 17 during the transit of the car, the arm 18 rocked upon its pivot removing the upper extremity thereof from beneath the transverse rod 13 w (1 previously tremity thereof. nected to the transverse bars 13, it is manifest that these links also move downwardly thus allowing the transverse rods to gravltate to a position which permits two of the hinged bottom sections C to assume an or discharge position. Each arm is successively tripped permitting the material in the car to be discharged through the space of the car through vertithe slot 14- .as v

D at spaced intervals between'the adjacent pairs of hinged bottom sections C, which operation is automatic as will be readily understood.

Bridging the ties D-between the tracks A is a substantially arch-shaped member 18 whose function is to return the bottom sectionsC and their associated parts to normal position. tom sections C is brought into engagement with the arched member 18 the two sections y reason of their connection with thelinks 11 are simultaneously elevated to their normal or closed position. During this movement of the parts the transverse bar 13 connecting said links is also moved to the upper extremity of the slots 14. As above stated the arms 15 are pivoted above center for the purpose of unbalancing the arms, so that when the bars 13 are moved upwardly As one of each pair of the botwithin the slots 14, the arms 15 gravitate to their normal position wherein the upper extremities of the arms support the bar 13 thus holding the bottom sections C efiectively closed. An inspection of the drawings will disclose the fact that my invention is applicable to new and old cars without necessitating alteration of the latter, and while the invention is extremely simple in its nature it is very eflicient for the purposes intended.

While it is believed that from the foregoing description the nature and advantages of the invention will "be readily apparent I desire to have it understood that the same is merely illustrative of the preferred form of the inventionto which I do not limit myself, and that such changes may be resorted to as desired as fall within the scope of the appended claims.

What is claimed is 2- 1. An automatic car dumping appliance comprising in combination with a car adapted to travel over a track and having hinged bottom sections and vertic'allydisposed slots, of a pair of spaced parallel transverse bars, links connecting the opposite extremities of said bars, one of said bars supporting the free end of each bottom section, the other of said bars being movable posed slots, means for supporting the last mentioned bar elevated to hold the bottom section normally closed, trip members at the opposite sides of the track for automatically releasing said means to permit said section to assume a discharge position, and an obstructing member disposed between the tracks for engagement with said section to automatically return the latter and its associated parts to normal position.

2. An automatic car dumping appliance comprising in combination with a car adapted to travel over tracks and having a hinged bottom section and vertically disposed slots,

in vertically disof a pair of spaced parallel transverse bars, links connecting said barsat the extremities thereof, one of said bars supporting the free end of each bottom section, the other of said bars being movable within vertically disposed slots in said car, arms pivoted upon the car and adapted to support the latter mentioned bar elevated to hold the bottom section normally closed, trip members at the opposite sides of the track in the path of movement of said arms to rock the latter from beneath the permit said bottom section to assume a discharge position, and an obstructing member arranged between the tracks for engagement with said section to return the latter and its associated parts to normal position.

last mentioned her to 3. An automatic car dumping appliance.

comprising in combination with a car adapted to travel over tracks and having a hinged bottom section and vvertically disposed slots, of a pair of spaced parallel transverse bars, links connecting said bars at the extremities thereof, one of said bars supporting the free end of each bottom section, the other of said bars being movable within vertically disposed slots in said car, arms pivoted upon the car and adapted to support the latter mentioned bar elevated to hold the bottom SEOtIOII normally closed, trip members at the opposite sides of the track in the path of movement of said arms to rock the latter from beneath the last mentioned bar to permit a discharge position, an obstructing member arranged between the tracks for engagement with said section to return the latter and its associated parts to normal position, and said arms being pivoted above the center to gravitate to'its normal position beneath the latter mentioned bar.

In testimony whereof I aflix my signature.

JAMES H. BAKER."
