PORTABLE MIXING PLANT.
Application filed March 7, 1918 Serial No. 220,897.
To all whom it may concern: I Be it known that 1, JAMES C. FRENCH, a citizen of the United States of America, and resident of Chicago, county of Cook and State of Illinois, have invented a certain new and useful Improvement in Portable Mixing Plants, of which the following is a specification.
This invention relates to machines for mixing concrete or other materials to be used in paving streets, and more particularly to portable mixing plants of that kind in which means are provided for carrying the mixture from the mixing machine to the desired place on the street. I
.Generally stated, the object of the invention is to provide novel and improved means for delivering the materials to the mixing machine, in combination with suitable means for receiving the mixture'from the mixing machine and carrying the same to the desired place on the street, whereby the necessary materials can be liftedfrom' the ground at either side of the mixing plant, or from the rear thereof, converted into the required mixture, and then delivered to the street at either side of the paving plant, or at a point directly in front thereof, thus enabling the body of the mixing plant which carries the mixture to occupy practically any position while in operation. and whereby the general operation of delivering the materials to the mixer and conveying the mixture from the mixing machine to the street is greatly facilitated.
It is also an object to provide certain details and features of construction and combinations tending to increase the general efficiency and desirability of a portable mixing plant, of this particular construction.
To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of aportable mixing plant for street-paving purposes,
embodying the principles of the invention, showing a portion of the apparatus broken away for convenience of illustration.
Figure 2 is a diagram of the h'bisting apparatus by which the materials are lifted I up and delivered to the hopper of the mixer.
Figure 3 is a diagrammatic plan View of the entire portable paving plant, illustrating the operation and range of movement of the Specification of Letterslatent.
Patented May so, 1922;
apparatus for hoisting thematerials from Y the street, and of theoperationand range I of movement of the means by which the mixtureis delivered to the street. I I
As thus illustrated, the invention com prises a body 1 mounted on wheels 2 which I may travel on a track which'is advanced from time to time in the direction in; which the paving operation is progressing, or.
which may be adapted to travel directly on the ground, depending upon the circumstances and requirements of the work. On this body a rotary mixer 3 is mounted, of
any suitable character, and operated by the engine 4 which is also of suitable character and supplied with steam from the boiler 5, the pow-eretransmitting connections between the mixer and theengine being controlled in I any suitable manner, ,It will also be udere stood vthat one or'more of the wheels 2 can be connected with said engine, so that power I may be employed formovingthe machine along the tracker along the streetr vThe apparatus for conveying the mixture from the mixer is as follows :,-A horizontally disposed boom or runway '6 is pivoted at 7 to swing up and down, on the lower end of a swivel 8, which latter. is suitably supported on the body frame" of the machine. With this arrangem 'e'nt, the boom can swing laterally about the vertical axis provided by the swivel 8, having its outer end supported by a brace 9 suitably con nected tothe body frame at 10, whereby this boom or runway can extend laterally or forward in any direction. A wheeled carriage 11 travelsonsaidboom or runway-andsupports the bucket-12, which latter can be of any suitable character, being operated by the pulling-out cable 13, when it is desired to pull the load to the outer end of theboom, and being returnedby the pulling-in cable desired manner. I As shown, the bucket is of the clam-shell type, the two sections bel hwhich latter also controls the dumping operation. of the buoket'in any-suitable or ing pivoted together at 15, I and suitable, I Y mechanism (not shown)'being provided for releasing the bucket and allowing the twof ij.
sections thereof to separate when the initial pull is exerted onthe pulling-inrope 14-, after the bucket has traveled outward and".
reachedthe desired placeofdischarge @The a two ropes or cables aresuitably arranged to extend upward through the swivel 8 and.
over the sheaves 16 and 17 and then down ward to the drums 18 and 19, the latter being operated by the engine through the medium of any suitable pou er-transmitting connection, as by being gear-connected to the rotary mixer, and controlled inany suitable manner to operate the two ropesor operation of the mixing plant in variousways, apparatus is employed for hoisting the materials from the ground and delivering them to the hopper 20, as follows :The rearwardly and horizontally extending boom or runway 21 swings on a vertical pivot or swivel 22 at the top of the body frame of the machine, and extends rearward directly over said hopper. A wheeled carriage 23 travels on said boom or runway 21 and has a bucket 24 suspended therefrom. This bucket can be of any suitable character, such as an ordinary clam-shell bucket, composed of two sections which are pivotally connected at 25, so that the two sections will separate to receive a load, will then close together to take up the load, and will thereafter separate to dump the load. The bucket is suspended by the links 26 pivoted to the bucket at 27, in the usual and wellknown manner, and provided at their upper ends with a pivot 28 having the sheave 29 for the suspending line or cable 30, which latter is fastened at one end to the outer end of the boom at 31 and supported by the sheaves 32 and 33 on the carriage 23 which travels on the boom or runway. This hoisting or lifting cable 30 then extends to the sheave. 34: on the body frame of the machine, and then downward to the drum 35 on the lower portion of said body frame, which drum may be operated and controlled in any suit able or desired manner. The bucket dumping line 36 extends downward around the sheave 37 on'the axis of the pivot joint 25, then upward and around the sheave 38 on the axis of the pivot joint 28, and then downward to the point 39, where its end is fastened to the structure of the bucket. This line 36then extends over the sheave 40 on thecarriage 23, and then forward and over the sheave 11 on the body frame, (the sheaves31 and 41 being arranged side by side") and then downward to the'drum 42 below,-which latter can be operated or controlled inanylsuitable or desired manner. With this arrangement,it will be seen that operation of the drums and 42 will lift the bucket, and that the cable 36 will, by reason of its arrangement around the sheaves 37 and 38, close the two sections of the bucket together to pick up the load. On the other hand, after the bucket is raised, a backward rotation of thedrum 4L2 and the -resulting slack conditions of the line .or vcable 36 will allow the weight'of thepivot joint 25 and the central portion of the bucket to move the sheave 37 downward, while the pivot joint 28 remains stationary,thus causing the two sections of the bucket to tilt away from each other and to dump the load into the hopper 20 previously described. Any
suitable arrangement can be used for swinging the boom 21 from one side to the other, and with this arrangement-the bucket 2 f can descend at either side of. the mixing plant, pick up a load, and then travel upwardly and forwardly on the boom until it is over the hopper 20, thus making it un necessary to supply the materials for the mixture at any particular place on the grounchinasmuch as the bucket candescend anywhere within reach of the apparatus and pick up its load.
Any suitable means can be employed for causingthe carriage 23 to travel back and forth on the boom or runway 21, and the latter can be of any suitable or desired length; As shown in the drawings, an operating chain 43 is fastened to the carriage 23 at 44: and then extends around a sheave 45 and then forward tothe sheave t6 near the swiveled end of the boom, and then rearward again to the point 47 on the carriage 23, whereby the latter forms a connecting link between the two ends of this cable. The shaft 18 for the sheaveor pulley 46 is also provided with a sprocketwheel 49 and the latter is provided with a loose sprocketchain which hangs down within reachof the operator on the platform 51, which latter, it will be seen, extends over the mixer and around the hopper, whereby the operator or attendant can control thedifferent instrumentalities. Another operator will stand onthe platform 52, for the purpose of controlling the discharge of the materials for the mixer, and to control the bucket 12 and the boom 6, whereby one operator will control the delivery of the materials to the mixer, and the other operator will control the delivery of the mixture from the mixer tothe street. I
lVit-h the foregoing arrangement, it will be seen thatthe materials can be dumped in one pile, or in different piles, around the rear end of the machine, or at either side thereof, or at any distance within limits at the rear of the machine, andthat the bucket 24 can then be employed for raisingv the materials in the desired manner and for dumping; them. into the hopper 20- of themixer. This is illustrated in Figure 3, from which it will be seen that the boom 21 can swing to either side of the mixing plant to enable the bucket 24 to receive its load. After the mixing operation has been completed, the materials are then discharged from the spout 53 into the bucket 12 at the delivery side of the mixing plant. The boom or runway 6 can be swung around in any direction, and in this way the mixture can be discharged onto the street at either side of the mixing plant or in front thereof, as the work of paving progresses, in a manner that will be readily understood. The body 1, however, of the machine or mixing plant can stand in any position, practically, for the materials for the mixture do not have to be moved up to or dumped in any certain position at the rear of the machine or mixing plant, and after being transmitted through the mixer the materials forming the mixture can then be discharged onto the street at any point within the range of movement of the boom 6 Y 7 upon which the delivery bucket is mounted to travel back and forth over the area of the street which is being paved.
As the carriage 23 forms a link in the belt 43, the latter is, therefore, practically endless. for through the carriage it forms an endless operating connection which is supported by wheels 45 and 46 and which can be controlled by rotation of one of said wheels, as explained, by means of the depending or dangling sprocket chain 5, or by any suitable means.
