This telescopic chute we ropose to mount in such a way that it can e adjusted to any required elevation within limits and we also propose to provide an elevating bucket by means of which the concrete may be lifted from the level of the mixer and delivered to the said chute when the latter is working in its higher positions. The rear end is fastened to the ends of cords 0. The bucket 0 for taking the discharge from the mixer la and delivering it to the chute p is balanced in a frame at raised and lowered in guides y by means of a cord 2 wound on a drum 4. In the trench the usual appliances will be used for guiding the concrete to any part desired see Fig.
The engine also supplies the power for driving the belts Z Z of the conveyer h by means of chains or their equivalent indicated by dotted lines at m m, power for elevating the mixer feeding buckets n n, the chute feeding bucket 0 and the chute 79 itself. The present invention has reference to apparatus for the use of contractors and others employed in work where a large amount of concreting is to be done, as for instance, in making dock walls and the like and the object of the invention is to provide means whereby the work can be carried out more expeditiously than heretofore. If preferred however the measuring hoppers may be dispensed with and the men in the trucks can throw or guide their contents direct on to the belts in which the sand would come from one direction and the rubble from another and join each other in the bucket n where the proportions would be measured by a vertical division while the cement is added by the attendant in the required proportions. Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. Beneath the measuring hoppers are traveling belts working toward a central point where the vertical system of buckets above mentioned is situated. These buckets are manipulated by cords passing over pulleys to winches q g. The trip mechanism 5 comprises a notched disk 8 fixed to the side of the bucket 0, as shown in Fig. The chute p which is telescopic see Fig. In testimony whereof we have signed our names to this specification in the presence of the subscribing witnesses. These frames carry endless belts Z Z which are arranged in any suitable manner and are worked from the engine on the machine 6. The rear end is fastened to the ends of cords 0. To save time the concreting appliances are made to followup the excavators and building appliances as closely as possible but there is much delay owing to stoppages in one department to make way for the other to proceed. In carrying our invention into effect we lay alongside the place to be concreted a line of rail uponwhich move the excavators or the cranes for handling the, soil or building Parallel with this line and behind the same is another for the trucks which are to-receive the soil du out of the trench or to feed building materlals. Straddling this second line of rail is a track for the concreting machine which is supported on a carriage designed to pass over loaded trucks and locomotives without touching them. Upon the carriage are a number of measuring hoppers which can be filled with the ingredients of the concrete from the supply trucks alongside. The bucket 0 for taking the discharge from the mixer la and delivering it to the chute p is balanced in a frame at raised and lowered in guides y by means of a cord 2 wound on a drum 4. In the work of this description it is usual to employ appliances for the excavation and removal of the soil, for the supply of building material, brick, stone, and the like and for the de livery of concrete to the trench. In the accompanying drawings a form of the apparatus is illustrated in which Figure 1 shows diagrammatically in'end elevation an apparatus suitable for building l a'dock wall of concrete according to the system of the present invention. A is an end View of the apparatus drawn on a larger scale and in greater detail. The pawl drops into the notch of the disk and serves to hold the bucket, while being raised, in a vertical posi-. At the back of the track of the concreting machine is a track for the trucks which bring supplies for the same and be tween this track last named and the concreting machine track is a parallel track for the specially designed feeding appliance of the concreting machine which appliance moves to and fro with the latter as it works up and down the track during the progress of the work. Next the track b is a wide track Z on which runs the carriage of the concreting machine, which will be described hereafter in greater detail. When the bucket is raised to the position to be tipped, a tail piece extension 10 of the pawl 9 comes into contact with the underside of a cross bar of the frame t, as shown in Fig. Instead of arranging the track for the feeding appliance or conveyer between the concreting machine track and the track of the supply trucks, the former may be arranged if preferred between the lines of the supply truck track, and contents of the trucks may be discharged on to the feed ing appliance through trap doors or their equivalent in the said trucks. To all whom it may concern:
