I sea known that 1, WILLIAM rgn eiimi, a citizen of theUnited States of Amer-ic'a, re-Z .I 'sidin at Brooklyn, in the county of Kings ,-and-' tate ofNewzYork, have invented cer tain new and useful 1m rovements inCon- .cr'ete Construction, of W 'eh-the following is J ther object beingto provide such a device" a: s ecificaticn, such asfz'will enable thosev skil edin the art to which it appertains to make; and. use the same;

This. nventlon relates to concrete; con-j struction, and has for its object to provide a;

device to accurately age the distance'f-beeq .tweenthe sides of the' orm''as, for'instance,

in the'fformation' of awali of concretea fur-1 I whichwill" become a component part ofthe j wall when finished without the possibility of une ual shrinkage due to climat c conditlons or o defacing the said wall from rustor simi lar decomposition,- and a still further object" being toproVidesuch a de'vice which'issim ple in construction and very inexpensive and whichpermits of' readily placing and disformations! lowing specificationfof which the 'accom placing the form necessary for such concrete My-invention is fully described in the fbl panyin drawings-form a part, in which suitthe several parts in each of the views, and

the formation thereof.

Heretofore the'removal the form from a completed section of wall hasbeena difficult and tr ,ing operationbecause of the 'factthat the b0 ts" or other devicesernployed to retam the members 'of the form position have necessitated great foi'ce-inthe removal thereof and generallyresulting in apartial de struction of the wall and it is to overcome this defect that my invention was conceived,

and beingfcornposedof substantially the' same material not alon'e amal amates and is invisible, but alsoipreven'ts t e running of rust streaks, which would result from the use of. metal tubes, and is also much more ecobe made of-any desiredshape'flor sizeand any number of the 'samemay be employed," and various other changes in and modifications ofthe form shown and described may be m'ade without departing from the spirit thereof or sacrificing its advantages.
