Specication of Letters Patent.4
Application filed March 28.1906. Serial No. 308.592.` I
Toull 'it-may concern:
^ Be itknown that I, Amori I; SPRAGUE, a citizen 'of the United States, residing at Rutherford, in the county of BcrgemiState of New Jersey, have invented certain new and useful Improvements in Hollow-Concrete-Wall full', clear, and exact description of the invention, such as will enablelothers skilled in the art to which it appertains tornake and use thesanie. f
`This inventionI relates to molds for forming concrete walls and has for its object to provide amold of this Vertical continuous air shafts which may be used for a portksimple in A further object ofthe invention is to provide able mold of this charac-.ter which will be construction and eicient in action. A l
In the accompanying drawings: yFigure 1 is an elevation'of a portion of a wall showing my invention in use. Fig. 2 is a top plan view showing the constructionof the is a vertical transverse sectionalview on the line 3- 3 ofFig. 1., Referring tothe drawings, the numeral denotes the wall formed by the mold and provided with vertical continuous air shafts 6. y
A pair of frame members 7` include each a connecting are boards 1 1 which serve asthe sides of the mold, the
readily understood.'
i`ntn'rn'ed-' ends of thefarms 8 of `the frame as will vbe Extending transversely of the frames 'land engaged through openings in thearms thereof are boltrods'lZ which are providcd'at one of theirl ends wit-h nuts and at the other of their ends with leyes 14 through each of which latteris engaged a bolt l5.4 Pivotally mounted upon the: bolt 15 is a cam clamping member including a bifurcated cam head 16 and an operating handle or lever 17. Asshown, the eye of the bolt rodis received in thevbifurcation in. the cam head and disposed between the said head 'and the adjacent armof the frame isawearplate 18,. l
vIn order to form the air spaces ,or shafts, I provide expansible cores each vcomprising a pair of members 19 which are hinged at their upper meetingedges; the ysaid `edges being correspondingly recessed for the 'passage o'a rod 20. yThe rod 20 is eniarged atits lower end to form a wedge' 2l, the lower end of which is enlarged asiat 22 to prevent its. entire withdrawal through registering recesses 23 in the lowermeeting edges ofthe secs 'tions Voi the core. At its upper end, the rod 20 is provided with a handle 24 by means of which `the rod may .be moved 'up or down toe'xpand. the core orto'allow "the saine to contract;
What is claimed is:A f V Y. A device'` of 'the class `described comprising mold ineinbers arranged 'in Ispaced relation',l means for ccunpressingf` the mold members, cores -arranged intermediatel the mold members and ineludingeach a pair of sections closed at each end, the Ysaid sections being provided at'. the edges of ltheir lowery clo's'ed .ends with registering notches,v and a Awedge core expandingjmenlber located in 'the coresl and 70 .p rovidedupcny itssaid wedgefportion andv helow the lower' with 'al'head yfor preventng'its disengageextending-witlr'its wedge portion through the notchesnnd endof said core ment from..the core. i
