SPECIFIGATION 'formingpart -fLtters Patent No. 2es,o33,dated november 6, 1.883.

' Application med october i, ieee. '(N model.)

Be it known that I, CALVIN- DETR'ICK, a citizen of the United States, and a resident of ANew cess of Making l[he Same, of which` the follow- My invention consists of a conduit composed of a tubular lining of thin metal clothedwith end-pressed cement of a define d;shap e, as described hereinafter, my invention also con sisting of the process described hereinafter of making the conduit. y

In the accompanying drawings, Figure 1 is a transverse section of a conduit made according to my invention; Fig.` 2, a diagram il-lusand Fig. 3 a sectional view of the Vmachine into effect.

. Referring to Fig. 2, and supposing A to be a tubular casing of a form corresponding withl G a lining-tube which is to forma permanent part of the said conduit7 and whichis preferably made of thin sheet-iron, if the'space be-4 tween the tube and thel casingA be packed cement, for instance, which will bccomelhard and sections of tubing added from time to time,

ing-tube, or, rather, succession -of sections of tubes, cloth ed with a thick solid mass of cement,

the cement being insured by end ramming the no such solid cover of cement c an be made by' rammng it round a' tube contained in a trough open at thetop to permit vertical rammingas by`horizontally packing the material roundl a tube contained in a tubular casing.

As the application of the cement to the tube by hand would be a tedious operation, I use the of a separate application for-a patent bearing even date herewith.` i

The casing A, which may be of the form shown in Fig. 1, containsa ram, B, which can be reciprocated in the casing by an operatinglever, D, through the medium of 4any desired mechanism, that described in my said applical tion for aipatent being preferred.

A guiding-tube, H, is secured to the rear end of the casing A, and passes through the ram B, aiming tube, (3f, passing through the sai d guiding-tube.

When an underground conduit has to be laid, a trench of suitable depth is dug in the ground, and the above-described machine is 4placed on the bottom of this trench', after Whicha section of the lining-tube G is passed throughthe guiding-tube H. Semi -plasticv 'cement is placed in the hopper M, which com-` munic'ates with the interior of the casing A,

an attendant being at hand to feed the hopper,

`While another attendant Vibrates the operat-l ing-lever D. The consequence of this will be the end packing of cement round the liningpipe G. As the operation is continued the entire machine will slowlyand intermittently packed cement presents to the ram, and Ythe recede', owing 4to the resistance which'the receding machine leaves a conduit consisting Itl-isfziiot necessaryto adhere to the-'form '.of.

casing' shown in Fig.. 1, but in carryingout my invention it is necessary that the casing,

Whatever may be its form, shall betublular, y

and-that the cement should be packedendwise in the casingfaround the lining-tube-,so i.that

'the cement solidly and uniformly com-A pacted.

My invention is not restricted toany specific i material for 'the liningtubes. '-Thcymay in some `conduits be of substantial paper or` cardf board; but generally they will be of sheet-iron,

Iori

stance, than stove-pipe iron-fer the lining- 'tubes are sbstantiallyre-enforced by thetubular packing of cement7 and are protected thereby from all injury. l.

I prefer in all cases to coat the lining-tubes with pitch or suitable varnish or pigment before they become part ofthe conduit.

I claim as my inventionl. The mode herein described of forming condui'tsfthe said modo consisting in clothing a lining-pipe with cement compacted within a tbular casing by'rmnming-it into the end thereof, s slet Aforth, and advancigthecasing' from time to time, I1,11 substantially as specified. 1 5

continiions coa-ting of i l.cement compacted to a l y deinedlexternal form, as set forth.

In testimony whereof .Ihave signed my name4 2o 'to this specification in'the'pres'ence of two subscribing witnesses.
