-tipplieation filed August 15, 191B. Serial No. 577,168. l 'l To all 'whom t may concern:

Beit known that I, Grenen F. Dimas, a citizen of the United States, residing at Baltimore, in the .Stateof Maryland. have 5 invented certa-in new and useful Improvements in Mold Ap aratns, of which the-following` is a speci ication.

This invention relates te an improyed mold apparatus for use during the fortnition or building of tunnels, sewers or similar structures in a continuons hollow form of concrete, cement, brick or other material.

Onel object of the invention is' to provide.

- an improved construction of mold sections which may readily beexpanded, contracted. and' "transferred as the building of the structure pro resses, I

Another obgect is to provide an improved construction of mold section and carrier 20,'whereloy one section may readily be collapsed and' moved forward through other lexpanded sections so that the respective sec- -ti-ons may be used repeatedly.

A further object is to provide an im- .A-provedV construction-of mold conveyer and .4Q in a collapsed condition. p Fig. 3, is a. similar view through a tunnel structure and slfows the improved lower mold members or sections susta-ined in a collapsed condition by the conveyer or carriage. Fig. 4 a side elevation of, the carriage and the devices thereon for expanding or collapsing the mold ysections and also shows by broken.

lines, the manner of sustaining and carrying the contracte-d upper and lower sections;

- Figs. 5, 6, 7 and 8 are diagrammatic side views of aqportion .of a tunnel or sewer showingt-he several mold sections in placey and the manipulation or several positions of thec'arriage in taking down and set-ting i yand Fig. 9 menores-sec-` tional viewthrough amoldstructure having a slightly modified form,,o'f'expandingllaiid contracting devices but embodying the features of my invention.` y

Referring to the drawings,.1,fdesignatesi a carrier of any preferred',construption but in the presentinstance it consistslofaframe of side bars, 2; and cross-bars 3,."which 4 are mounted on wheels, it, thatftravel, on y.track rails, 5, which latter aresustaine'd 1. e J"er-""155 ably in a manner hereinaiterlto cdeJ scribed. Suitable bars, 6, are sustained on the frame andy extend upwardly'tlicrefrom and in .theprcsent instance. these` bars'far'e arranged in pairs,-two at eaclrendfof the earrierand incline more or less-toward each other so that their upper ends may sust-ainy horizontal 'b eams, 7 inI .a'cen'tral' position over the frame as clearly seen in'll The bars, G, may be bracedin `any desirable manner with respect to each otherjandalso I with respect to the carrier framey soas to make them sufficiently rigid andfstrong' to serve the purpose of supports, as shown in', Fig. 4. "80

A rod, S, has a vertical position withf'respect to the carrier, 1, and inthe forms shown in Figs. 1 to 4t inclusive is sustained at its lower end in a bearing,9, on thc" carf v rier and its upper endenters suitablesofckcts" or plates, 10, that are attached tothe horizontal beams, 7. This. rod, 8, .-isprovided with,.screw threads, 11, vso that a suitable hand wheel, 12, or equivalent device maybe made to travel vertically thereon :by engag 90 infr said threads. A head..13, loosely-,engages the rod, 8, and rests upon the.upperside of the hand wheel orother dev ce,12, that travels on the rod and said head (pivot-l /j y sustains the inner'ends of spreaderbars, 95 14, which extend outwardly froml said. head and which,end may be raised.i or lowered with the vhead asthe handwheel o r other device is moved vertically onl` the rod;

are provided with a plurality oflbiackets, 15, which are secured -t-heretointermedia'te its ends, as clearlyseen in.Fig.;4,anldfs,a1d brackets pivotally sustain the vinner ends of described. L

The mold sections -mayfvary inffnumber arms, 16, the outerends of'whichlatterare 105- beams, 7 also for a purpose presently to be 110 according to the character of the work nnder construction, but in forming a complete circular tunnel or sewer as illustrated 4in Figs. 1,2 and 3, I prefer to employ tour sections denoted by the numerals, 19, 20, 2i and, 22, respectively, The sections comprisea structural frame work, 23, havinga curved outer chord, 24, which carries laggingy plates, 25, thatcompletely cover the frame. ln a horizontally longitudinal di-V rection the plates that cover the frame may vary in breadth and width but they are -usually as broad as they can be made withl out interfering with their ready handling.

The'sections are arranged in pairs,-the sec# tions, 19, and, 20, comprising one pair and Vthe sections, 21, and, 22, comprising the v they mayswing'with respectto each other 4from a central `vertical line through the other pair. In the formation of a complete circular tunnel or sewer both pairs of mold sect-ions will lbe employed as shownin Fig.

. 1, wherein it will be noted that the sections,

19, and, 20, have position at the upper side of the4 arch andthe sections, 21, and,.22, at

the lower side thereof. The -sections of each pair are. pivotally connected at, 26, so that tunnel,` By this connection the free ends, 27,`of the sections may be swung inwardly toward the vertical rod to collapse or convtact Athe sectionsv or moved outwardly from saidrod to expand the same( Inl order to Veo pivot, 26, to expand or contract said sec-l tio s.

t will he noted, by' referencel toFig. 2

l t at when collapsing the mold sections from kt e position shown in Fig. 1 to that shown inFig. 2 the adjacent pivotally-connected ends of the section will drop away or move downwardly from the highest point of the arch a suficient distaneeto enable them to clear and 'be passed or moved through other expanded 'sect-ions.

(In practice, after a lower mold section or' pairof sections has been properly placed or positioned,the upper pair of sections will be moved into position and expanded. While held in they expanded condition, suitable connecting bars, 30, are bolted to plates,

the respective 31, which are provided on The spreader frames for that purpose.

.bars, 14, andv pivoted arms, 16, -may then be disconnectedfrom' the mold sectionsland Loana-ee l the carrier moved to the rear of vthe tunnel' or' sewer' to he engaged with other mold sectionsand carry the latter forward to hef. set up; Splice bars, 32, 'are' proizidedA adjacent the circumference of the meld' sec m. tions to secure the ends ofthau per and Y lower sections together, as, seenin ,"igil.

The rails, 5, .on which the'earrier trayets f p are sustained on renio'vahley cressgbeains, 3%: 'which rest upon' the 'lowergumold sectional 75' 21, and,`22, whichbe'anis'a'iie removed before the said sections are col-lapsed.'

In the form shown inFig. gfthernlilld i sections, 34, and, 35, are pivotally connected l at, 36, and a rod, 37is sustained at oneencl Nj at the j'oinder ofj'thetwo sections and ex tends betweenl the two sections` and at ri ht: angles to the pivot. This rod has .thescr wthreaded exterior, 38, and carries a head,39 and handwheel, 40. The spreader hars 41, each have onev end pivo-tally eo'nnecte `with the head on` the rod andntheir etherends pivot-ally engage the frames'pf",the" mold sections. It is therefore ohviousif/that the movement of the.head on the will cause the spreader. bars to lexpand or. collapse the sections. In this instance the mold sections are sustained on a carriage, 42,.that` y is movable on rails laid for that purpose.

The operation of collapsing, ltransferringand again setting up the forms or 'sections is diagrammatically illustrated in Figs. 5

to.8 inclusive. By reference to Fig., 5 it will be noted ,that the carriage is sustainedl on a light rail-supporting structure, 43, so my that the carriage will be vin position i'n the Aupper and lower mold sections that are to be collapsed and moved forward. While in 'this position the spreader bars, 14, will be connected to the sections, 19, and, 20, and l the. arms, 16, from the beams, 7 also connected to said sections. The connectin bars,

30, and splice bars, 32, will then be isconnected to free the two pairs of sections whereupon the l1and-wheel, 12, may be op- 110 erated to allow the free ends of the sections to swing toward each other or collapse as seen 'in-F ig. 2. The carriage will then be moved to one side with the collapsed section sustained thereby as seen in Fig. 6, so that the forward end of the beam, 7, may have a position substantially centrally l over .'the` lower sections, 21, and, 22, so that the blockv and'fall, 17, may be engaged with the plates, 31. The tracks, 5, and supporting beam, 33, 12o are then removed fromy the lower section whereupon said sections may be raised by the block and fall and at the saine time collapsed as shown in Fig. 3. A short rail is then temporarily placed between the structure, 43, and the rails in the expanded form ahead so that the carriage supporting the two collapsed sections may be'rolled for-` wardly through the expanded forms to the opposite end where the formsare to be set up again as seen in Fig. 7. When the collapsed forms have beencarried through ister with .the lower sections, after which the connecting bars, '30,'and curved plates, 32, will be attached to the upper and lower sections tp rigidly secure them in place. The spreaderbar's, 14, and arms, 16, may then be disconnected from the sections and the' carriage returned to repeat the operation on the succeeding sections as' soon as the concrete has set sutliciently` to permit their removal.v

By means' of this invention the mold sections maybe readily set up, expanded and j secured together and as readily collapsed displaced and moved forward and the constructionworkat'on'e end `of 4the tunnel or sewerthus be carried on. without interruption.

-Having f thus' described my invention what I claim and desire to secure byv` Letters Patent isf 1.` In a portable and expansiblel mold apt paratus the combination wlthfa 'movable carends and above the riage aplurality of structural 4metal frames pivotally cxnected at their upper rriageand each frame carryingl curved plates; a screw-threaded rod extending vertically between the carriage'and the pivotI joint at' the upper ends of the structural'l me'tal frames and said rod l extending centrally' between the lower free ends of the opposed structural frames; a

head on,v the exterior of the said threaded rod; a ,o tatabl head engaging the threads of the rod'andhavingposition atl oney side oi theI head whereby to move the head longitudinally on the rod; an arm at one side of .the head and having its inner end pivotally connected tothe head and its outerY end piv- 'otally engaging the'structural frame at one side of the rod; another arm at the dia- "metrically-oppo'site `side-x01? the said head and having its inner end pivotally-connected .to the .head and its outer end pivotally engaging the structural 'frame at the other side ofthe rod whereby the movement ofthe ro- 'tatable`head Aon the threaded rod will cause the inner'pivoted en'ds`of the arms to move vertically at opposite sides of the rod and simultaneously swing the free ends of the opposed structural `iframes equal distances with, respect to the said threaded rod.

Q, In a portable mold apparatus the combinationwith a movable carriage of a frame sustained and extending labove the' ear' mage; a rigid' rod extending vertically fromI the carriage and havingits upper end held by the frame; a head on the rod; means for moving the head longitudinally on said rod;

mold sections extending over the frame, rod and carriage and having their 'ends pivotally connectedabove the upper endiofgthe rod;

an arm at one side of the rodfand having one end pivotally lengaging thehead on the rod and its other end pivotally engaging one of the. pivotally-connected mold-sections; another arm at the opposite side of the rod and having one of its ends also engaging the said heady and its other end pivotally connected with another oit/the sai pivotallyconnected mold-sections, and vmeans traveling on the rod at one side of the head for moving the latter longitudinally on said rod to simultaneously swing the free ends of Ithe pivotally-connectedmold sections toward or from the rod. 4'

43. In a portablel mold the combination with a carriage, of a rod extendingfrom the carriage and' having screw threads; a beam sustained from the carriage and extending bo'th to the front and'at the rear of the said rod; spreader arms radiating from about the rod; arms extending laterally from the beams andmold sections carried by the arms yand spreader bars.

bination with 4tw'o 'pivoted lower mold' sections and two pivotally-connectd upper mold-sections and each mold section having a structural frame work; 'of means for connecting the adjacent ends of the upper and lower mold-sections whereby to forni a complete circular mold; trackers and supporting means carried by the' two lower'mold sections; a carriage movable on said tracks; means carried by the Carriage for engaging, collapsing and carrying the lower' mold sections, and means carried by the carrlagc for collapsing and conveying the upper inold sections to move said lower and upper mold-sections while collapsed through other expanded mold sections.

In testimony whereof I affix my slgnature in presence of two witnesses. l
