Specification of Letters Patent.

Patented May 17, 1921.

Application filed January 2, 1920. Serial No. 349,031.

To all whom it may concern:

Be it known that I, CLARENCE J. WESTON, a citizen of the United States, residing at Fort Dodge, in the county of Webster and State of Iowa, have invented a certain new and useful Conveying-Receptacle, of which the following is a specification.

My invention relates to conveying receptacles of the class in which the body is made in two transverse sections hinged together at their tops, and wherein the dumping of the contents of the car is effected by unlatching the hinged sections and allowing them to drop downwardly and apart.

It is my object to provide in connection with a conveying receptacle of this type, means whereby the hinged sections may be automatically unlatched by engagement with a trip lever permanently stationed at a desired point on the track.

A further object is to provide means whereby the hinged sections can be automatically righted after the contents have been dumped.

With these and other objects in, view, my invention consists incertain details, in the construction, arrangement and combination of the various partsof the device, whereby the objects contemplated are attained, as

hereinafter more fully set f0rtl1,pointed out in 'my claims, and illustratedin the accompanying drawings, in which:

Figure 1 shows a side elevation of my 1mproved conveying receptacle in position for dumping. I

Fig. 2 shows a similar view of the receptacle in closed position.

Fig.3 shows an inverted plan v1ew of my improved conveying receptacle.

Fig. 4 shows a rear elevation of the same; and

Fig. 5 shows adetail View of the adjustable means for raising the sections.

Referring in detail to the accompanying drawings, I have used the reference numeral 10 to indicate the wheels ofthe' receptacle; -11 the hinged sections comprising the body, and 12 the track upon whi operated.

Arranged transversely of the receptacle at-the-outer end of'one of the sections is a crank shaft 13 mounted in bearings 14and provided'with crank arms 15 extending upwardly or downwardly at either side of the receptacle. A. red l6 is extended through tion where it is normally in engagement oh 'the car is;

the crank arms. Pivoted to either end of the rod 16 is a link 17 arranged longitudinally at the sides of the receptacle and extending forwardly to a point near the inner end of the adjacent section, where it is pivoted to an upwardly extending arm 18 formed on a hook shaped lever 19. One end of the rod 16 is projected outwardly beyond the side of the lower portion of the receptacle, as shown at 20, anda bracket 21 fixed to the link 17 is employed for bracing the projected end ofsaid red.

A contractible coil spring 22, fixed at one end to the side of the body and at the other end to one of the links 17 is employed for yieldingly holding the links 17 in their forward position. The lever 19 is pivoted to the side of the bodysection as at 23 and. extends forwardly to the abutting body seowit-ha roller 24 carried on a stud 25 fixed to the adjacent body section. In this man ner the lower adjacent ends of the hinged body sections are held together in position for receiving their load.

Secured to the upper parts of the sides of the sections near their inner ends on each side of the car, are bars 25 and 25, extending upwardly and toward each other when the car is in normal position. The arms on the two sections on the respective sides of the car are pivoted together at their ends.

For automatically releasing. the hook shaped levers to thereby dump the car, the following means is provided: located at the desired point on the track is a standard 26 preferably secured to a tie and extending provided with a weight 28.- On the arm 27 is a stop 27 arranged to coact with the arm 27 to limit pivotal movement of the arms 27 and27 relative to each other.

a p All of these parts arearranged at theside of the track in position to clear all parts of a passing oar save the projecting end 20 of th(e1 rodl'ole. Thisi (ilf'the rod is desi e to' e engage t e upwardly iex tei ding end ofthe l'eviir 27 as the "car is moved along the track; A chain 28 and strongspring 28 are connected with the arm 27 and'a fixed member, and together with 4 the lever '27 are sulficientto hold said lever 110 when the rod 16 engages its upper end and thereby the rod will be moved rearwardly on the crank arms, carrying with it the links 17 thereby raising the hook shaped levers upwardly and out of engagement with the roller sleeved lugs. If the car moves farther the weight is lifted before any parts are broken to permit the car to clear the arm 27. When the car moves in the opposite direction, the lever arm 27 swings on the arm 27 without lifting the Weight in such a way as to do harm.

Obviously the body sections will part at their lower ends when the hooks have been released, and will thereupon drop to the position shown in Fig. 1 of the drawings.

For returning the body sections to their closed position, the following means are provided. Positioned near the center of the track at a point in advance of the dumping position of the car is a roller 29 mounted in a standard 30, which standard is permanently fixed to one of the ties on the track. Beneath one of the body sections near its inner end and in line with the roller 29 is secured an erecting cam 31. As the car is moved forwardly along the track the roller 29 is engaged by the erecting cam 31, see Fig. 1, and the body section is thereby moved upwardly, carrying the adjacent section with it. As the sections are moved upwardly and toward each other, thebeveled end 33 of the hook shaped lever 19 will move over the roller 24 on the stud 25 until the roller enters the hook portion of the lever. The rod 16 and the spring 22 operate to hold the hook shaped lever 19 always in position to effect a contact of the beveled end of the lever and the roller 24:, so that in returning the body sections to their closed positions an engagement of the hook shaped lever and the roller is always assured.

Mounted. upside down in the lower part of the cam 31 is a round headed screw-threaded bolt 32 capable of adjustment by means of washers, so as to engage the roller 29 and insure the final raising movement of the car sections in spite of any variations in the positions of the cam and the roller 29, due to wear and so forth.

On each car section is a stop device 100 adapted to engage the track and limit the dumping movement of the sections.

In practical operation, it will be seen that when the car is filled and moved along the track to the point where it is desired to dump the contents thereof, the trip lever 27 will unlatch the sections and permit them to drop to their dumping positions. In the act of dumping the projecting end of the rod 16 will be raised enough to pass over the lever 27, and the cam 31 will, after the car has traveled a short distance, engage the roller 29 and thereby the parted sections will be moved to their closed positions.

The car then may be continued in the same direction for another load, or, if desired, it may be returned over the same track and in this latter case, the erecting track will slide over the roller 29 without interference, while the trip lever 27 will be easily swung a sufficient distance to permit the projecting end of the rod 16 to pass over it.

The advantages offered by my improved car are obvious, for it is seen that the operations of dumping and righting the car are entirely automatic requiring no attention whatever from the operator. The simplicity and arrangement of the several parts of my device render possible a durable and inexpensive construction, which are also advantages in a device of this class.

My improved dumping and erecting means are particularly adapted for use-in connection with a string of cars, and as the string of cars is moved in one direction along the track the cars will successively dump and right themselves in the manner described.

It is to be understood that many changes in the details of the construction of mydevice may be made without departing from the spirit of my invention.
