Application filed July 2:,

This invention relates to a concrete. con-.

veying and distributing cart, and especially to a cart ofthis character which is particularly adapted for delivering, distributing and'spreading wet concrete in a series of successively arranged molds.

The object of the present invention is to generally improve and simplify the construction and operation of carts of the char-.

. acter described; to provide a cart which is It Is also provided with supporting legs 14,

adapted to straddle a series of molds placed end for end in line formation and to be moved longitudinally thereof; a cart from which the concrete begradually' discharged as it is being moved with relation to the molds, so thatthe successive molds may be filled; and further, to provide adjustable means whereby the flow of the discharging concrete may be regulated and the final height of the termined.

One form which my invention may assume is exemplified in thefollowing description and illustrated in the accompanying" drawings, in which Fig. 1 is a perspective View of the con crete conveying and distributing cart;

Fig. 2 is an end view of the same, showing it in position with relation to a mold.

Fig. 3 is a cross-section of the. vertical end of the concrete cart, showing the position of the gate and the guide flanges supporting the same.

Referring to the drawings in detail, and

particularly to Figs. 1 and 2, A indicates in general a V-ahaped hopper supported by; wheels B. The hopper consists-of avertical 'end section 2, an inclined end section 3, and

a pair of vertical side sections 4. The lower portion of the vertical end section 2 is cut away to form a discharge opening 5, and a gate 6 is vertically movable with relation thereto to close the opening or to partially or fully uncover the same when concrete is being dischaged. The'gate 6 engages the forward face of the end section 2 and is held in sliding contact therewith, the gate being tion to the end section 2. A pair of crank arms 9 is secured to the shaft and these crank arms are connected through links 10 with the gate. Shaft 8 is also provided with a crank concrete in the molds de- 192s. Seria1No.'727,667. I

handle 11 i which is manually controlled. This crank handle when pulled in one directionturns shafts 8' so to raise thecrank arms 9, the links lO-and the gate 6. llfovement of the crank handle 11 in the opposite direction reverses the movement. The discharge opening may thus be, closed or partially, opened-as desired by the operator.

The cart is otherwise provided with a. push bar 12 secured to handle extensions 13.

spreading device consists of .a plate 15 disposed in front of the gate 6- and on an-angle with relation thereto.- The plate 15 is secured to the end sections 4 of the hopper by means of side plates 16. These side ,plates are 'inturn provided with supporting legs or shoes 17 which are adjustable with relation to the plates 16-; that is, the upper ends of the shoes are slotted as shown at.18 and bolts .19 extending through theslots and secured in the plates 16 permit vertical adjustment of the legs. H y

The cart is particularly adapted for use inconnection with a new method of molding concrete blocks andglike devices,. such as illustrated and described. in my issued patent v entitled Method and apparatus for manufacturing hollow concrete building blocks.- issued July 28 1925, Patent No. 1,547,530. Briefly the method consists in placing a series of molds endfor-end in line formation on'a suitable support, such as indicated at 20. Runways 21 are formed on each side of the support and V-shaped grooves or tracks are formed in the runways for the reception and guidance ofthe wheels B.

The concrete wet-mix is formed in a suitable concrete mixer and the like and is dumped into the hopper of the cart. The cart is then advanced over the runways illustrated and is guided by the V-shaped grooves or tracks.

The cart will thus straddle the molds indicated at 24 and each mold will be. successively filled by opening the gate 6 as the cart is advanced. The amount of concrete discharged is regulated by'the position of the gate and the levelling or spread ing plate 15; that is,.the concrete might have a tendency to'bunch in places, but it is even 1y s read out and a uniform height in the mol s is obtained by the plate 15 as it serves a levelling and spreading device; the

I position of the plate 15 with relation to claims.

.. I claim and desire to secure by Letters operated lever movement to the gate, a combination spreadthe molds being determined by the shoes 17, which are held in frictional contact withthe runways as the cart is being advanced. If it is desired to spread the concrete, so that it will project one-fourth of an inch above the molds, it is only necessary to adjust the legs 17 so that when the card straddles the molds and is advanced with relation to the same, a clearance of onefourth of an inch will be obtained when the legs 17 contact with the runways. A greater or less clearance may, of course, be obtained by changing the adjustment.

It has heretofore been common practice accomplished in one operation when the cart here shown is employed, and a saving in both time and labor is thus obtained.

While certain features of the present invention are more or less specifically illustrated, I wish it understood that various changes in form and proportion may be resorted to within the scope of the appended I similarly wish it understood that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer maydictate or various uses may demand.

Having thus described my invention, what Patent is- 1. A cart of the character described, comprising a concrete receiving hopper having a discharge opening formed in its lower end and extending substantially from side to side of the hopper, a sliding gate vertically movable with relation to the opening for closing said opening and for regulating the flow of concrete therethrough, a manually for transmitting sliding ing and leveling plate carried by the hopper, and'wheels supporting and permitting longitudinal movement-of the hopper.

2. A cart of the character described, comprising a concrete receiving hopper having a discharge opening formed in its lower end,

a gate movable with relation thereto, manually-actuated means for opening and closing the gate and for regulating the flow of concrete through the discharge opening, andin said late bein dis osed on av vertical.

inclination with its upper edge closest to the hopper, an end plate on each endof the spreader plate and. a connection between each end plate and the hopper.

' 4. In a device of the character described, a hopper which. is V-shaped in cross section, a substantially vertically disposed end plate in the hopper and having an elongated dis charge opening formed in its lower end, a

gate vertically slidable on the end plate for opening or closing the discharge opening and for regulating the discharge of concrete, and an inclined spreading and levelling plate carried by the hopper andv disposed rearwardly of the discharge opening.

5. A wheel supported cart of the. character WOLCOTT P. STANTON.
