Application filed September 20. 18171- Serial No. 193.211.

To u/Z UllO/H it may; con/11m lle it. known that l. IlENRY li. Porrnn, a citizen of the United States of America. and a resident of Sonora-ville. in the county of Middlesex and Coininomvealth of Iii-assachusetts, har ini'entecl certain new and use fol Improvements in Drunp-tarts. of which the following is a speciiitation.

This invention relates to dump carts and particularly that class of carts used for the delivery of coal. sand. and similar materials and it has for its object the production of a vehicle of this character in which the delivery of the. material may he controlled from the seat: of the operator.

The invention consist primarily in a swinging tailhoard provided with means for regulating the opening: between the lower edge thereof and the honour of the receptacle to which said tail board is pivoted. combined with a coacting delivery ctmtrollingmember hinged to said bottom and adapted to be moved into various angles with said bottom.

The invention further consist in certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claim to be hereiinit'ter given.

For the purpose of illustrating the invention one preferred form thereof illustrated in the drawin this form having been found to give sat i factor and reliahle results. although it i to he understood that; the variou instrumentalities oi which tho invention consists can he variously arranged and organized and that the invention is not limited to the precise arrangement and or ganization of these instrumentalities as herein shown and described.

Figure 1 represents an elevation of a vehicle emhod vin the principles of the present invention.

Fig. 2 represents a rertical section of a portion of the rear end oi the same.

Fig. 3 represents a similar view showing the receptacle tilted about its pivotal connection with the truck.

Fiimilar characters designate like parts throughout the. several figures of the drawings.

in the drawings,

10 is the frame of a motor vehicle which may he of any usual construction.

The frame 10 is mounted on wheels ill-11 and near its forward end is provided with a seat 12 for the operator. At the rear end of the frame 10 are two brackets 13 having a rod l-l extending: therethrough. this rod L also extending through the l tudinal I-heams 15 forming a part sit the support for the bottom 16 of the receptacle 1? having the side walls 1S-lS.-and the end Wall 19.

A rod 20 extends through both side. walls 25* and suspended from this rod 20 is a swinging tail hoard 21 normally retained in the closed position indicated in 'lii 2 h the rod 22 disposed in the alined he c5 in the side walls 18.

\i'he-n traveling over the road the t il hoard Q is in closed positioiu unless it i; L sired to deliver a limited amount of sand. -'e or similar material up n the surhice the road.

In order to accomplish this deliver}; of erial the rod is another set of alined openings i "d in Fig. 3 thus permitting the to wing farther to the rear and lea e an o ning 24.- heta een its lower edge and the bottom 16 ot the receptacle 1?.

i'i hen the receptacle 1? is tilted nit angle to the truck 10 by n'ieans of an lifting device. 23. the material may the bottom it; through the open ()lYVlOllS that when the receptacle l position SllOWll in Fig. 3. an even clerery of the material therein will he accomi hed.

his evident. however, that in dep sand. gravel and similar materials up surface of a road it is desire. at ti deposit a greater qnantit of mate. one place than at other places and some it is desirable to cut oil the deliver ent it is apparent that it would he very oi tionaole to be obliged to stop the l'OZlFQiG tail boa:

- pi votally and adjust the various instrumcntalities when it is desired to accomplish these results. v

To meet this diliicultv and make it possible for the operator to control the delivery of material from his seat 12 is the main object of the present invention,

This control is accomplished by the delivery controlling-member 26 hinged at 27 to the rear end of the bottom 16 of the receptacle 17.

Each end wall 30 has pivoted thereto at 31. a link pivotallv connected to the slidable bar mounted in guides 34 evtendin laterally from the truck frame 10. v

The bar $3 on the left of the vehicle is connected to the short lever as shown in F ig. 6, the upper end of said lever 35 being, indicated in dotted lines in Fig. 7.

The lever 35 is secured to the rocker shaft 36 which has also secured to its opposite end the controlling lever 37 pivotally connected to the bar 33 on the right side of the vehicle.

The 11 )per end of the controlling lever 37 is provided with the usual locking device adapted to coact with the notches 39 in the quadrant 40 to retain the delivery-controlling-member 26 in adjusted position.

The rear ends of the. bars 33 are provided with recesses 41 in which the outer ends of rod 14. are positioned. these ends servingas guides for the rear ends of the bars 33' in their reciprocating movement.

Vi hen the delivery-controlling-member '26 is in the position indicated in dotted linesin Fig. 3 and the receptacle 1? is inclined as shown the material in said receptacle will have as free a delivery as is'possible through the limited opening liithout changing the size of the owning. the deliver of material may be retardedbv simply moving the (leliveiw-controllingmeinber intp position shown in full lines in Fig.

If the delivery-controlling-memher 26 is moved into the position shown in Fig. 2 the deiivery will be cut oil altogether.

t will be obvious therefore that by means of the movement of the delivery-control!in member 26 about its pivot 27 any amount of material may be delivered or the delivery entirely discontinued and this movement of the delivery-controlling-member 26 is under the control of the operator Without leaving his seat 12 or stopping the vehicle.

The amount of deliver of the material may be further varied by changing the position of the tail board 21, but with the tail board 2] in any adjust-ed position and varying the size of the delivery opening 24, the regulation of'the delivery through the opening'Ql will continue to be under the control of the operator,

32, the opposite end of which is the swinging movement of said This device is of great advantage in vehicles used in connection with the construction and repair of roads.

It is believed that the operation of the invention-and its many advantages will be fully understoodwithout further description.
