UNITED STATES LLOYD A. BOLTON, OF CHICAGO, ILLINOIS,
A SS-IGNOR TO WELLER MANUFACTURING COMPANY, on onroaeo, ILLINOIS, a CORBORATION on ILLINOIS.
METHOD OF AND APPARATUS FOR BACK-FILLING.
Application filed April 18,
To all whom it may concern;
Be it known that I, LLoiro A. DoL roN, a citizen of the United States, and a. resident of Chicago n the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of and Apparatus for Back-Filling, of-which the following is a full, clear, and eXact-descrip. tion. 1 The invention relates to apparatus and a method for use in connection with laying or building sewers. Heretofore, it has been the common practice to excavate a trench and deposit the soil at one side of the cut or trench, and leave it there until the sewer has been laid or built. Then it is shoveled back into the trench.
T he present invention is designed to avoid the necessity of depositing, the excavated material alongside of the trench and to hack-fill the trench with material removed therefrom without depositing the soil.
This object is attained by providing an apparatus which is adapted to convey and I take care of the excavated material from the time that it is removed from the cut until atter the. sewer has been laid or. built and then backfill it.
In providing apparatus to attain this re-, sult. the necessity of depositing the, eXcae vated material on the road or ground at the. side of the cut avoided and back-filling is greatly expedited.
The invention consists in the several novel features hereinafter set forth and more par: ticularly defined by claims at the conclu sion hereof.
In the draw ngs: Fiourel is; side eleva-. tion of an ap aratus embodying the inven-i. tion; Fig 2 is a vert cal tra-nsverse-, section taken on line2- 2 of Fig. 1. Fig. 3-is a plan of that portion of theapnaratuswhichreceives dirt "Tom-the cut. Fig. 4lis a side, elevation ot the same Fig, 5- is asection talren on line 5-5 of Fig. 7-. Fig. Gisan end elevation ot the receiving apparatus. 7 is a vertical longitudinal section of the receiving apparatus. Fig. 8 is an endelevation. and Fig. 9 is a plan of the apparatus tor delivering dirt back into the cut.
The apparatuscomprises e sentially a re.- ceiv nor apparatus A into which the dirt isv deposited usually by a steam shovel, a dirt carrier B supported upon a series of trucks T C, and adelivery. apparatus-D;the convey Specification of Letters Patent.

being of sufficient length to retain and handle the material from the point where it is point where the cut is to be closed or where back-filling is tooccur. alter the sewer has been laid or built. 'The receiving apparatus A is sustained by a wheeled truck a and the delivery apparatus is suitably sustained by a wheeled truck (Z, so that the entire apparatus can be advanced on rails 10 to keep apace with the digging and back-filling of the cut. The receiving apparatus comprises a hop per 11 having inclined sides 11 and vertical ends 11, supported by a framework 12 which is built upon thetruck a. The hop per 11" is open at the bottom so that the material in the hopper will fall therethrough onto an endless pan conveyer 13 which travels. around sprockets 141 on a shaft 15 and sprockets 16 on a shaft 17, which'are mounted on thestrame-worlt 12'. The upper reach of this pan conveyer is suitably guided between said shaft-s on tracks 18 which are supported by cross beams 19. The lower reach of said conveyer is supported on tracks 20. This 'conveyer is adapted to gradually conveythe material deposited in the hopper 11 to an endless conveyer belt 21 which is of suilficient length and capacity to retain the material to the point where bachiilling is to be done. The pans or buckets of conveyer 18 serve to regularly feed the dirt away from the hopper, the end 11* being extended to prevent excessive loading. Cutter blades 22 on a shaft 23 are operated to break up the material as it falls from the pan conveyer 13 onto the belt 21 of carrierB. I
Theirereiving endof the endless belt 21 passes around a pullev 24: on a shaft 25 which is sustained bytheiframework 1-2 on and below the pan convever. The cutter shaft 23 is mounted on frame-work 12. A
Between the receiving and delivery apparatus, the upper reach of the conveyerbelt 21 is supported on pulleys 36 and troughing rollers 37 which raise the margins of the belt to retain the dirt. The shafts of these pulleys and rollers are mounted in bearings fixed to the sills 38 which are adapted to rest on the wheeled trucks 0. These sills are not fixed to the truclrsto permit some flexibility when the apparatus is being moved around a curve. A suflicient number of these trucks are provided to sup port the conveyor belt B between the receiving apparatus and the delivery apparatus, which are spaced apart a sutlicient distance to retain the material from the point where 1t 15 received from the cut to the point where the sewer has been laid or built and the trench is to be filled.
Atthe delivery end of the apparatus, the
a pulley 51 supported by the frame-work 52 on the truck (Z or" the receiving apparatus,
and a" pulley 53 mounted adjacent the outer end of a conveyer-Irame 5 1 whlch is pivotally connected to the frame 52 so it can be swung. vertically to vary the point at which the material will be discharged from the belt A suitable hoist 55 is mounted on the framework 52 to adgustthe cable .56 which supports the conveyer frame 54. The
In operation, the material eircavated from the cut or trench is deposited into the hopper ll at the receiving endof the back-filling the material in regulated quantity from the.
hopper and deposits iton the endless troughconveyer 21, the cutter 22 serving to disintegrate and break up the material so that it will be in condition to be used for back-tilling. The conveyer 21 retains and conducts the material and ultimately discharges it into the hopper 57 which deposits the material into the cross conveyer 50 which conducts it sidewise to a point where it will bacl fill the trench after the sewer has been laid. All of the apparatus is driven in synchronisin so that it will operate to dispose of the material in regulated quantities and as the excavation and filling occur, the entire apparatus will be moved "forwardly on the traclg to constantly maintain thereceiving apparatus, in position to receive the filling and to advance the delivery appara tus as the trench is filled. The entire apparatus may be continuously driven.
The invention thus exemplifies apparatus which. isadapted to receive the excavated material as the trench is formed and to retain it and convey it continuously to the point where the trench is to be-filled' after the sewer has been laid or built. The apparatus avoids depositing the material onto the roadway ttnd the necessity of picking it up to subsequently fill the trench, and also exemplifies a method-for back-filling which avoids depositing the soil onto the roadway or at the side of the cut.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
Having thus described theinvention, what l'claim as new and desire to secure by Letters Patent, is: p
