CONCRETE CONVEYING AN'Iy MIXINGCART.

Specieation of Letters Patent. Application filed December 21, 1908. Serial No. 468,560.

To all whom it may concernf Y Be it known that I, Fnnnmcx H. vLA- United States, and a and State of Illinols, have invented certain new and useful Improvements in Concrete Conveying and Mixing Carts, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, suliicient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to devices used in paving cement roads, side walks and cellars.

The object of the invention is -to obtain a device by means of which sand, broken stone and cement may be conveyed from the several piles thereof, adjacent to rthe place where the same are to be used, to such place and there deposited.

A further object of the invention is to obtain a device of the character described which can be easily loaded and quickly unloaded. i

A further object of the invention is to obtain a device of the character described which may be operated by the driver` or perl,

son in charge thereof in a manner to properly mix the several ingredients contained therein in what is termed a dry mix, and also to add water t`o such mixture and remix `the several ingredients, and thereby under the varying conditions which arise' 1n practical work to obtain .a mixture properly wetted or moistened. Y

A furtherxobject of the invention is to obtain a device of the character described which will 4be simplein construction, durable and not liable to get out of order.

The ens A, A, F, F, and K, K, with pipes D, and Lform the frame of the device and the pipe B which is a part of the frame also forms the axle of the device, such frame being reinforced or strengthened, when desired, by the couplings e, e, Z, Z, and the brace pipesY (or rods) E, E, and Z', Z'.

M, M, are the supporting, carrying and actuating wheels of the device and are provided with a hub which turns freely on the axle B, and with spokes m, m. l N is the carrying and mixing receptacle of the device. Receptacle N is loosely mounted on the axle B.

O is a recess or socket in pipe L of the frame of the device. L

P is a bolt longitudinally movable in bearings p, p. Bearings p, p, are rigidly attached to one end of the receptacle N as by rivets or bolts p',.p'.

P' is the handle by` means of which bolt.

P is moved.

P is a dog arranged to alternately enga e with recesses P'", P'", on bolt P.

is a spring arrange/d to yieldingly Q is a plate rigidly secured to spokes m, m, of wheel M as by straps g, g, and g', g', are recesses in plate Q arranged to form sockets for the 'bolt P. f

The receptacle N is locked so as to rotate when the bolt is in socket O in the lframe of the device; and is locked to wheel -M to rotate therewith when such bolt P is in any one of the sockets g', g on disk Q.

The receptacle N is provi with an aperture through which 1t may be loaded and unloaded and R, R', are doors arranged to form the cover to such apertures. To hold the doors R, R', closed, the ends t, t, of levers T, T, are arranged to engage with abutments 7', r', on such door. Such abutments have rollers thereon shown in the drawings. Lever T is loosely. mounted on Eile B, such axle passing through the hole t' S, S, are stops secured to one end' of the receptacle N, arranged to limit the movement "of the handle t.

The lever T`which is located at one end of the receptacle N is attached to the like lever T at the other end of the receptacle by the beam or rod T so that the abutments r, r', at both ends of the doors R, R', are latched bythe said levers T, T, andimlatched when force is applied to the lever' at one end of the receptacle.

The operation of the device is ;-When a suitable quantity of cement, sand and broken stone has been put into receptacle N and the doors R, R', locked in a closed position, with the bolt P moved to engage with one of the recesses g' on disk Q, as the device is hauled along the ground the receptacle N is rotated simultaneously with the wheels M. By driving the vehicle along the ground at such time, (with valves 1, I, closed), the contents of the receptacle become well mixed while in a dry condition. Assuming the tank G to contain the proper quantity of water to wet or moisten the contents of receptacle N, after the desired dry mixture of the contents of such receptacle has been obtained, the valves I, I, are opened and the vehicleis driven a farther distance'along the ground and until a wet or moistened mixture is obtained.' When a thoroughly mixed and moistened mixture o f the contents of the receptacle N is obtained the device is driven to the placewhere the contents are to be used and the receptacle placed in the position Y thereof illustrated in Fig. 3 of the drawings. When the rece tacle is in this position the contents thereof rest on the doors R, R', and the handle t" of lever T is in position so that a person standing at the rear of the vehicle may force such handle down thereby turning said levers T, T, and drawing the end t of the levers out of engagement with the abutments r, frl The contents of the tank will then force the doors open and such contents will fall out of the receptacle to'rest on the ground'. The vehicle is then driven or drawn forward and the rear door, being prevented by stop U from opening beyond a given distance will scrape over the unloaded contents of the receptacle so that the edge u of such door will tend to level the load.

The board V is attached tothe inner .side

of the wall of the receptacle N by bolts a',

e', and the ballie plate W is secured to the receptacle is accelerated by such contents being carried up by board V and discharged ,on the baffle plate W as the vhicle is belr driven forward and the receptacle is`lock to the wheels M to turn therewith.

vThe ends 0I' the pipes C, C, which ,are in f' l the ells A, A, and the ends of pipes E, E, inl l couplin e; are or may be closed.

A su cient quantity `ofwateris putjinto tank G to properly meisten or wet the mix- Y ture obtained in ythe receptacle so that a.

properly moistened mixture. is easily ob# tained. Y v

1 do not confine myself to the use of. pipes or tubes in building)the frame" of the device, other than pipes ,"D, and-pi Ae B with nipples H,'H,`which are re uire to conve the water from tank G to t e rece tacle while the device is lbeing hauled ong the ground and the contents of the receptacle are being thoroughly mixed, as described.
