APPARATUS FOR MIXING AND DELIVERING CONCRETE AND THE LIKE MATERIALS.
Specification of Letters Patent. v Patented J 13, 1911 Application filed December 24, 1910. Serial No. 599,231.
To all whom it may concern:
I Be it known that we, ST. JOHN CLARKE, a citizen of the United Statesof America, and RUDOLPH Wnncxnn, a subject of the Queen of the Netherlands, residing, said ST. JOHN CLARKE at Bogota, county of Bergen, State of New Jersey, and said RUDOLPH WELCKER at Bronx Manor, city of Yonkers, county of Westchester, State of New York, have invented a new and useful Apparatus for Mixing and Delivering Concrete and the point of use (for instance, in the lining of tunnels or subways, or in the building of walls) at any plans with relation to the new apparatus.
While our improvements may, obviously, be embodied in many forms of apparatus, we have preferred to use (and have illustrated in the accompanying drawings) a Ransome concrete-mixer, of usual form, having added thereto a supply door, an improved discharge chute and a pipe for leading compressed air, or other pressure medium, into the discharge chute in the direction of discharge of thematerial from the mixer.
Referring to the accompanying drawings, Figure 1 shows, in vertical section, our new apparatus when used for delivering semisolids-such as mortar or concreteto a point of use, as between the wall of a tunnel and a frame. Fig. 2 is a like view of the machine when in use for receiving concrete materials and mixing the same.
A indicates the body of a casing-a Ran; some concrete mixer, in this instance-having also the receiving end B and the discharging end C. The mixer has the usual blades D, for stirring the concrete materials and for lifting and dropping quantities of the same.
In order to rotate the casingabout its axis, it has the usual external circular gear ring E, which meshes with and is driven by the pinion e. The mixer-casing also has the two usual track rings, F, F ,'running upon rollers when the casing is rotated.
The supply end of the casing has a fillin opening or port, G, and this port is opened or closed, as desired, by the sliding'of a door H, provided with an edge gasket, 1, for assuring an air-tight joint when the door is in fully closed position (that shown in Fig. 1). At its discharge end, the illustrated mixer 1s providedwith a plate, X, bolted in place and permanently closing the usual opening. A tubular continuation, O, hereinafter spoken of, passes through said plate, at the rotation axis of the apparatus, and said plate is free to rotate around the pipe while the pipe may be rocked in either direction and freely of the plate.
' A chute J, having a front wall K which thus completes a hopper from which the chute continues, is supported by an angle bar L in posit-ion to deliver concrete into the mixer when the door H has been pushed (as shown in Fig. 2) inwardly and the supply opening G is unobstructed all around.
For sliding the door H to either open or ,close port G, any suitable means ma be used. We preferably employ a pipe to which the door is secured. Said pipe is used also for supplying fluid under pressure (as compressed air) to draw mixed material from the casing and force said material to any desired point of use in manner hereinafter described. In order to supply fluid under pressure to pipe N, the latter is connected with a flexible or. other pipe, n, in turn connected with a source of compressed air. Near one end, pipe N is arranged to slide in a bearing formed in a part- M suspended from the hopper.
The apparatus has a discharge chute preferably, as before stated, disposed to rock about the axis of rotation of the mixer casing. In the form shown, the chute has a receiving hopper Q to the exit end of which a tube or tubular continuation O is secured. At its discharge end, the part 0 leads into a pipe, P, of a length and flexibility sufficient to deliver the concrete to any desired point of use.
The hopper Q is shown as provided with a flaring extension R, in order to increase its receiving capacity. At its rear end-that is to say, at a point in line with the tubular continuation O,the hopper has a projection S with an opening therethrough and adapted to constitl'itev a bearing for an end of the pipe N which, as before stated, is slidable. In its,. retracted position (causing door H to close the port G) the discharge end n of plpe N lies as shown in Fig. 1, so as not-to interfere with the passage of concrete from hopper Q to pipe 0, when the discharge chute is turned into receiving position. In its advanced position (causing the door H to open the port G),,said discharge end 11 of pipe N lies as shown in Fig.- 2, that is thrust forward into the tubular continuation O of the chute.
As will be understood, the chute is free to rock about pipeN, in order that the chute may be swung to either receiving or rejecting osition. To rock said chute, a handle, 0 1s connected to the part 0 of said chute.
In operation, and when filling the mixercasin the parts are as in Fig. 2-with the pipe I? advanced so as to have the door H in open position, while the handle 0 has been swung to give the chute Q, a half-turn. Concrete materials are then poured into hopper J and discharge into the mixer. When sufiicient material has been supplied to the mixer, the pipe N is pulled (to the right, in the-drawings) and door H closes port G. Upon rotation' of the mixer casing, the blades D agitate the materials and lift quantities of the same and then drop these toward the mass. The chute Q, being then turned so as not to receive material, assists in distributing falling concrete over the mass. While the mixing is going on, fluid undeii I pressure is not supplied through 1 e p is soon as the concrete materials are sufiiciently mixed, air is supplied through pipe N and'rushes through the part 0 of the discharge chute (the passage of the air thus giving the chute the property of an injector) and outwardly through pipe P. The handle 0 is now given another half-turn, and, as a result, the chute Q, is turned to a receiving position, that shown in Fig. 1; The door H being, as aforesaid, closed, in order to make the mixer quite air-tight, the continued rotation of the latter lifts quantities of the mixed concrete, and these portions are dropped into the hopper R of the chute and fall into the tubular continuation 0. At that moment, the concrete is moving in the direction of its discharge (toward pipe P) and is readily carried, by the compressed air, in that same direction, through that pipe, to the desired point of use. The
tendency, if any, of the concrete to clog the hopper Q, or to form a bridge therein, is overcome by the backing-up, at intervals, of quantities of air from the tubular continuation 0. Should such clogging or bridging take place, it is merely necessary to turn the chute to the position shown in Fig. 2, whereupon the material will fall from it. Upon return to the position of Fig. 2, the chute is a ain ready for action. ,7
While we .have, in practice, found the illustrated device to. be very efiicient and economical, we do not desire to be understood as limiting ourselves thereto.
We claim:
1. In an apparatus for handling concrete and the like materials, the combination of a closed mixer casing having a discharge port, with a hopper within and inclosed by the mixer casing, and having its discharge end communicating with said port, and meaps for injecting a stream of air directly into the outlet of said hopper and directing said air toward the discharge port, said casing having means for feeding concrete toward the hopper.
