$0 LZZ' whom, it may coiwern:

Be itknown that-I ,"VILLIAM E. DE LHoRBE,

a citizen: of the Unit-ed States, residing at Chicago,- n'the'county' oi' (cola and State of uois, have invent-ed a certain new and a useful Improvem'ent in Forms for Plastic Building lvalls, of-"which" the following isa specification.

Myinvention relates to forms'for use in the construction of buildingwalls torn'ied of cement, concrete,-

or other plastic material. a I It'is-c-ommon practice in building walls' of plasticmateri'al'to'employ forms of lumber or are built upin place and then removed, with the consequentloss material which constitiite s such -forms. 7 l I The object of my invention ist'o provide a form which may be used over and over again, shall be, practi callyspeaking, ndestructible.

and may be adapted to walls of various thick nesses and dimensions.

It is also an object to provide a torni which -may be-n'sed continuous ythat is, a form by means of whichthe wall maybe built up cont nuously. without actually removing the form, but merely elevating it' from time to time 3p the wall rises during the process ofconstruction. 0

I obtain my objects by-the apparatus illustrated in the accompanying clrawings, in

which.

Figure l is aside view of two interlocked forms.v Fig. 2 is a sectional view taken transversely through the wall, sh owing theforms Fig. 3 is an enlarged View of the spreading mechanism shown at the upper Fig; 4 is a sectional view taken on line 4 a, Fig. 3. Fig. 5 is a plan view of the part shown in Fig. fragmentary view showing a modification in modification int-he form of spreader. F igS 1s a detail view of a locking-block for securing adjacent forms together. i Fig. 9 is a detail view Illustrating the manner tached-thereto are tlie uprights l), which pro-' Fig. 6 is a rights I) and receive the tail-nuts h in such Fig. 7 shows another a j ect above the upper edge of plate at. These uprights consist of still beams of any suitable material and near their upper extremities carry a spreading device, which. may be constructed in variety. of ways. In the pre-' ierr'ed form (shown in Figs. 1 to 5, inclusive) said uprights are apertured at b to receive anotched, corrugated, or otherwise roughened spreading-bar c, which I prefer to arrange'up on edge in the manner shown. Said apertures I) are large enough to permit the free passage of bar c without engaging it, and in order to maintain the upper extremities of uprights b at a sui'licient distance apart clamps (Z are located just inside of said uprights and are-adapted tobe bolted or otherwise rigidly adjustably secured to said spreading-bar. I The spreading device, however, may assume other forms-for example, the one shown in Fig. 6;

In the form of spreader shown in Fig. 6 the spreading-bar e'is perforated at'regular distances, and the uprights b are correspondingly perforated to receive a pin which when passed through both the upright and the spreading-bar holds the upper ends of two opposite uprights at a fixed distance apart. A second modification in the form of spreading-bar is shown'in F igifi, in whichbarf has right and leftthreads thereon adapted to screw into the nuts f, contacting the inner edges of two opposite uprights. 1

Preferably at or near the upper edges of plates a are-located tension devices for 'coop' crating with the spreadingbars to draw the lower portions of the plates together. In the preferred form this drawing means consists of-screw-threaded rods '9, adapted to pass throughthe suitab'ly-apertured upposition that said nuts contact the outer sur- 'faces of said uprights. In order to protect rods 9 from the cement or other material which-is thrown between the plates for the formation of the wall, said rods are protected 100 which consists in the illus- I of telescoping or interfitting Thegreason for employing of pipe is to render it posby suitable armor, tration, Fig. 2,

pieces of pipe 11. telescopic sections sible to protect the full length of the screw :05

when the plates "are at different distances apart. The ends of the plates are matched, for example, in the manner shown in Fig. 9, inwhich the uprights at the ends of the plates are set in slightly from the end of one plate 11b from the surface of t and set out sli htly over the edge of the other plate. In orfer to fasten the ends together, any suitable device inay be employed, the preferred form-being shown in Figs 1 and 8. In this form studs j reject perpendicularly he uprights, and a yoke or double clip is is provided, whioh is so constructed as to it over said studs, and thus hold the plates together at the ends.

In operation the plates are brought to a proper distance apart by adjusting the uprights 1) upon the spreading-bar c and drawrod g. The cement or other plastic material of which. the wall is to be composed. is then introduced between the form-plates a, over the upper edge thereof, until the top of the .wall has reached up to, or nearly up to, the upper edge of said plates. The wall is then permitted to harden suflieiently to maintain itself, when the nuts h are backed d,. thus loosening the plates from the wall, at which time the entire apparatus may be lifted until the lower edges of the platesengage the upper extremityof the wall as far as finished.

The nuts h are then tightened again until the plates are again brought. to a proper distance apart, when the operation of introducing more of the plastic material .is repeated. Thus the operation is continuous, for the form-plates may be raised up from time to tiihe as the wall grows higher and the same apparatus, although comparatively small.

in height, will serve to build the wall from bottom to top. After the wall is completed the 'apparatus may be entirely removed and employed for other walls in a similar manner,

seams What I claim, and desire to secure by L etv V tions of the adjusting mechanism for protecte ing the same.

2. Apparatus for forming plastic buildingwalls consisting of plates adapted to forin the surfaces of the walls mechanism for adjusting position of one plate with reference to an opposite one and telescoping cover membersbetween the plates covering one or more por tions of the adwstmg'meehamsm for protectmg the same.

3. Apparatus for forming plastic buildingwalls consisting of plates adapted to form the surfaces of the wall; uprights rigidly fastened to said plates and extending above theupper edge thereof adjustable spreading-bars at the upper ends of said uprights; a threaded rod located below said spreading-bars; tele-" scoping cylinders on the outside of said rod for protecting the same; and nutssorewing on said rod and contacting the outsides of the apparatus for governing the distance between the lower portion of said plates.

In witness whereof I have-hereunto subscribed my name in the presence of two witnesses. g
