GIMHR, a citizen of the UnitedStates, residing. at

Be it knowrithat I, RICHARD La Fayette, in the county of'Tippecanoe and' State ofl Indiana, have'invented certain new and,useful Im rovements `in Cement Col= uznns, of which t 1e following isa specification.

...ln thernanufacture of columns from. artilicial stone difficulties have beenexperie'nced in producing them of the proper length and strength. v

Y Itis the object of. my present invention-to' provide a means whereby such columns-may e produced, 1n one p1ece,. of-there uired length and size, and inay-also'be abun antly strong for the duty required: .e

Said invention consists in .the construction of a suitableniold and in :fthe .combination thcrewitlnof anv ap ropriate core; the novel features: whereofwi l 'belhereinafter fully de- Referring to the accompanying. drawings, upon .which similar. reference characters 1ndicate similar parts, Figure ..1- is a perspectiveview ofsuch a mold and core assembled, the: sides of the 4mold being swung aparfghow-l ever, to show. thecore'in place .within it;q Fig. 2 a detail verticalsectionahview of the'apparatus withth'emold sides'.broughttogetherE closing the mold,- the middle portion, how-.

The mold is composed of a base 2l and an I' inclosing structure ol the shape desired (usually substantially cylindrical, but somewhat tapering) which structure is preferably composed of three parts 22, each of zwhich, for convenience, is composed of two pieces a and a. These three pieces stand on the base 21 surrounding an end piece 23 to the mold, and are secured together by heavy strap hinges 24 at a suitable number of points. l have found (in molds for columns of the usual length) that three sets of these hin es serve the purpose. The arts a a of eac section are usually secured by heav straps 25. The end piece 23 is secured to t e'base 21, and is the up er en of' the shape and. .size'foffrtha ltvterll endroftdw column to be made. *.Whrr-:tirelanoldisnasa sembled the sides lit clcselylsaonndathls and piece, and vare held tightly@teviether-r.#byl suite ingedl fte-imanable locking .devices .etniche DoWel-pins- 26 hold the adjialcent-ddgesnlll parts 22-'inflush relationiwhen :iaa`11fse. a'.

In arranging this mold for-use, the mold is first erected to an u )right position, substantially as shown in ig. .1, and the sides 'of the structures 22 brought together and fastened. The core is united to the end piece by means of a pin 36 projecting from the center of said core and entering a corre spending hole in the center of' the end piece 23. A corres onding pin 37 extends up from fof the core, and a cross bar 3S secure to the sides of the mold (as by pin 39) engages with said pin, thus. holding said core strongly and accurately to the desired central position while the mold is being lled. After the main body of the column is formed, a neck may be added surrounding the up er pin 37 around which neck an ornamentalpcap may be placed. As the neck cxtends through'the cap, tl1e cap will not be required to carry any of the `load when the columnisin position. After the column is completely formed', the locking devices are unfastened' and the molds swung apart, and the column removed. i As will be readily understood,a core is used with every column which is formed; but the outer mold parts are capable of indefini'terepeatcd use.

Having thusI fully d e''crbed mv said invention, what I cla-1m as new and desire to secure by Letters Pn Lent` is 1. The combination, in a mold for articial stonecolumns, of a base, an end piece carried by said base forming'a head to the mold-chamber when the mold, is in` condition for use, an outer mold structure composed of sections hinged together, a tubular core having angular projections with 'a Wire wound around said core and resting on said projections but standing free from the body of the core, a at each end of the core for holding the same centrally Within the mold, 'one of said pins engaging with said end iece and the other pin engaging with a cross y ar at the opposite end of the mold2 and said cross bar.

2. The combination, m' a mold for artificial stone columns, of a suitable surrounding structure forming the walls of the moldchamber, and a core extending longitudinally through said chamber and secured centrally within said structure, said cores having longitudinally -arranged projecting ribs thereon and a wire' wund around said core and bearing upon suchribs, but held thereby a'way rom the adjacent portions of the core sur.-

3. The combination, in' a mold for artii Iicial stone columns, 'of a surrounding structure forming the outer walls of the moldchamber, and a core extending longitudinally through said chamber, said core being tubular in form and provided with longitudinally arranged projecting ribs upon its outer suresmas face, and a wire Wound around said core in contact with saidribs.

"4.y The combination, in a mold for artiicial stone columns, of an outer structure constituting .the walls of the mold-chamber, andI a core secured centrally within said chamber, said core being composed of a cen' tral wooden ieee, a sheet metal tube surrounding an secured to said wooden piece arid rojections in the form of Z-bars secure td t e external surface of said sheet metal tube. i
