UNITED STATES PATENT OFFICE.
@ALVIN DETRICK, OF KEW; YORK, N. Y.
sPEoIFzcATxoN forming part of Letters Patent No. 288,034, dated November 6, 1883.
Application tiled October 1, 18%3. (No model.)
.To @ZZ whom, it 11mg/ concern.:
Be it known that I, CALYIN DETRICK, a citizen of the United States, and a resident of New York city, New York, have invented a .Machine for Making Lined Conduits of Plastic or Senii-Plastie lllaterial, of which the following is a specification.
My invention consists ot' mechanism, fully described hereinafter, for facilitating the formation ot' conduits composed of cement, and lining` tubes round which the said cement is packed, my present invention being an improvement Yin the mechanism described in former patents hereinafter referred to.
In the acconipanying drawings, Figurcl is a sectional View ofthe machine for making the tube-lined cement conduit; Fig. f3. a sectional plan of Fig. l; Fig. il, a detached View ofthe mechanismwhcrewith to operate. the ram or plunger of the machine, and Fig. -t a perspective ricw of the tinished conduit.
The machine is in many respects similar to.
that described in Letters latent No. 220,757, July H, 15TH, and also in 'lateutsXos td,52.l, 272,410, and 272,411; but thel machine described in these patents was" constructed. Vfor the torlnatiou ot' conduits by packing` cement round a former or formel-s, which were retracted, leaving'an opening oropeniugs inthe cement, whercasthc present machine is foi-the, formation ot' conduits of which a tubular lining forms a permanent part.`
A casing, A, which is in the present instance 0f the form shown in Fie'. 1, contains an annular plunger or ram, l which can be rcci'procatcd in the casing bythe operating-lorca' i) through-the medium ofthe mechanism shown in Figs, i! aud 23, and referred to hereinafter.
'G is the tube, which is to constitute the lining ofthe conduit, and which may be made of thin sheet-iron, or eren ot'stiffpapcr; but the sheet-metal tubes made of thin spiral' strips secured atthe edges are preferred, '.lhe tubo tl passes through a ghidingtubc, il?, the end a of which passes `Litrinigh and is secured in any suitable mania-,ij` to the rear cud ofthe casing, as shown in ljig, l.
Any of the devices `shown in the abovementioucd. patents, through thewnudium of which the plunger is recipriu'atcd by vibrating the operating-lever, may be used, but I prefer the mechanism which I will proceed to describe.
A rock-shaft, l, to which the operatinglever D is secured, has its bearings on standards J, secured to the casing Aw-one on each side of the same-and to this shaft are attached two. arms, b, each of which is connected by a link, c, to one armof a lever, K, and to the outer end of a link, 17, which is hinged at e to the rear end ot the easing, the other arm of the said lever K being` connected to the ram B by a link, f. both sides of the guiding-tube (t, cach lever K having its rfulerum-liin la in an elongated slot in one of the standards J.
l'n the. aforesaid patent No. 272,410 the ram 'as operated .by alevcr through the medium of a toggle-joint,so that great power might be exerted on the ram, especially at thc couche sionof its for Yard movement; butin the pres entI instance there is on each side ofthe guiding-tube a duplex toggle-joint for imparting greater power to the ram, the fulcrum-piii 11.
sliding in the, elongated slotsin the standards .T as the operating-lever l) is vib'rated.
When an underground conduit has to be laid, a trench ot' suitable depth is dug in the ground, and the above-described machine is placed at thebottom of `this trench after which a section oflining-tube G is passed through the guiding-,tube 1I. The material iu which the lining-pipe is enveloped may consist of ordinary cement, which is originallyin a semiplastic condition, but which subsequently becomes hard, diilcrentmaterials and compositions being availablefor the purpose. Hence in using the word cement I wish it tobe understood that it includes any available material which, after being packed whilcgin a plastic or st mi-plastic state, will .eventually become hard. .l.` he material selected is placed in 'a hopper, M, which comnumicatesI withthe interior ot' the casing-- an attendant Ibeing at hand to feed this hopper, while another attendant vibratesthe operat ing-lever and there- There are thesev links and lever onv by rla'iprocates the ram, which slides iu the l casing and on the guidiug-tube It. sequence ot" this reciprocation-ofthe ram will bethe packing ofcemcnt round the lining` The cn-V y `pipe Gr.` As the operation is continued, the entire machiney will .slowly and intermittently recede, -1 owing to the resistance which A the y lpacked cement presents to; the ranfnand the receding machine will leave behind `it-,a con'- duit consisting. ofthe packed cement containing the lining-tube, which forms a permanent part of the conduit, the external `-shape and 'thickness of the packedccnient being determined by the shape of the casing A, which need not be of the precise form shown in the drawings. From time to time asthe machine recedes a section of lining-tube is fitted to the end Aof that Whichis being' clothed with cemr 5.
cnt,vso that a continuous conduit of any desired length may be made. I prefer in all cases to coat the sections of lining-tubing, no
mattei; of what material they may be coinp'osed, with pitch o1' suitable pigment.
,If the lining-tubing be `of metal, it maybe 'very thi'nand cheap, as it is re-'enforced in the inost substantial manner-bythe packed cem- E)entLand protected thereby `frein vall liability fte I )einjured externally.
l The conduit may be made for drainage purposes, or for water or gas distribution, for containing electric conductors, and for other. purposes.
vof which the ram is reciprocated by the said `operatingJever, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
