TIE BEAUTE' FOR CONCRETE FGRMS,

ltpplicaton filed January e, i921. Serial No. 434,983.

To all ici/0m t may caf/acera.'

it known that ller ri.

the llnited States, and a resident in the county of @nondaga and .Biete ot w Yori:`u have invented 'a certain new and useful Tie for Concrete .renza of which. the lollf'ivcing is a speciiicz tion.

This invention has Ator its object a tie brace -lor holflingl the opposing Walls of concrete :tornis in position or in parallelism to each other1 lwhich tie nrace is particuy simple economical in conetinoJion` remlily placed in position and in which. the parte thereof, not left inthe co* e l are read y removed, and nrtl oif wail. which is highly ei'iicient and durable in use. r.l-he invention consists the novel features and in the combinations and constructions hereinafter set Jorth and claimed.

ln describingthis invention, reference had to the accompanying drawingsin which lilre characters designater cerrespondingi parts in all the views.

fure l is a vertical sectional view et t "s brace, the contiguous part or Walls oif the forni being shown.

l'ligure 2 is a plan view or parte seen in lTi ligures 3 and 4 are respectively an end View and an enlarged sectional view of one the blocks or sleeves of this brace 're 5 is a perspective view of the tightening' Wedge. i

lhis tie brace comprises generally, opposieg` blocl-s or sleeves designed to lie against the inner opposing faces ofthe walls oi the forms, the bloclrsbeing formed with internal cavities having; lizey slots in their opposing ends, a tie rod having angular or laterally turned ends which are kmovable through the lrey slots and int-o interlockinigv engagement with the end walls of the cavities of the bloclcby relative endivise and turning movements of the tie rod andthe blocks, and means extending through the walls of the forni for pulling the blocks outwardly against the inner i'aces of the forni. Preferably, this means includes pnll rods Which interlock With the blocks in a manner similar to that in which the `tie rods interlock with the blocks. V

l designates the Vblocks which are here shown as conical in forni `with their larger ends or bases disposed outwardly in order *i lie against the inner opposing faces 2 oi? the forms each block being provided with an internal cavity 4 having end Walls which are formed with openings for the tie rod and the tension rods 8 As here shown, preferably, the openings in :h if the walls 5, G is in the' form of, j 'for cinivenience is called a keyhole t 9 or l0, that is. a slot extending subally radially oi the end `Wall of the liiocr; and in order permit a hook to hi fA zerted therethrough and turned to interlock with the end Wall, the tie rod 7 is prfgirided with angular or laterally turned hook v'g "l for enteriifig `the slots 9 upon relatfc cnf the blocks l and to interlock With the opposing end Walls of the blocks upon a relative turning n'iovenient of the rod to the blocks. The rods@ are provided with similar hoolrs l A interlock vii th the end Walls olf the cavity on the or sides 'of the block by siinilar inoreinents. Each block l is preferably provided with a partition as an internal an` nnlar flange l intermediate the ends thereof i'or spacing the ends oli the rods i', 8.

The rods 8 are drawn endvvise by a `particnlarly simple and cheaply constructed Wedge i3 which seen in Fig. il: is U- shaped in cross section, the Wedge being,r arranged astride the bill lll of the hook at the outer end of eachfrod 8, the bill le or the hook being substantially parallel to the major part of the rod 8.

ililhen rthe wedge is arranged astride the bill lll, the intermediate orback 1.5 thereoiif ir aojalnst the .'frainino' of the iorin l i l5 members. i i

@Wing `to the arrangement by Which the interioclinp,1 of the tie rods and `tension or pull on rods With 'the blocks or inserts 4 is se movement of the rod 7 and 2 at their inner ends arranged to sov iio

eifected, this brace is-readily placed in position when the concrete is set the Wedges, pull rodsand blocks are readily removed. Furthermore. owing to this construction7 and to the Wedge construction the Whole device consists of but few parts which are particularly economical in constriiction.

1n use, after the concrete Wall is hardened the tension rods 8 can be readily removed upon knocking outot the Wedges 18 and removing the rods 8 by a partial turning and endvise movement thereof. rllherea'iter, the walls of the 'form are removed, the bloclrs or inserts l() displaced and the holes lett therein filled up with cement.

l/Vhat l claim is:

l. ln a. tie brace for concrete forms, the

combination of a pair of blocks each 'formed with a cavity having a slotted opening at its -end wally a tiered having laterally turned hoolij shaped ends for interlocking in the cavitiesot the blocks by relative endvvise and turning movements ot' the blocks and the `tie rods to pass the hooks through the slotted openings and to engage the hook-shaped encs with the inner faces ot the end Walls ot the cavities7 and ineans for tightening the blocks in position, substantially as and -tor the "purpose described.

2. 1n a tie brace ior concretel forms, the

lcombination of a pair of blocks, each formed with a cavity having a key slot in one end i iv'allwa tierod having laterally turned hook shaped ends arranged to enter the slot-s `in` the opposing Wallsot the blocks and interlock theieif-vith in the recess by a relative endwise and turning movement of the blocks and the tie rods, tension rods and having hooks at their inner ends arranged to interlock in vthe cavities ot' the blocks through the outer end Walls thereof, and means for drawing the last mentioned rods outwardly, substantially as and for the purpose set forth. i

8. 1n a tie brace for concrete forms, the combination of a pair of blocks each formed with a cavity having key slots at their ends, a tie rod having laterally turned hook shaped ends arranged to enter the slots in the opposing` ends of the blocks and inter-y loclr in the cavities thereof by a relative rotation of the blocks and the tie rod,y rods i having hooks at their inner ends arranged to interlock in the cavities of the blocks through the key slots in the outer ends oi` the block, and means vfor drawing the las-t mentioned rods outwardly7 substantially as and for the purpose specified.'

et. In a tie brace for concrete forms? the combination ot a pair of blocks, each formed with a cavity having openings at its end Walls, a tie rod arranged to interlock at its ends in the cavities of the block by a relative endvvise and turning movement of the Lerares Y rod and the blocks, additional rods arranged end to end With the tie rod and having means at their inneil ends arranged to interlock in the cavities oi the blocks respectively by relative endvvise and rotary movement of such rods and the blocks, and means for .tighteningthe last mentioned rods, substantially as and tor theV purpose set forth.

' 5. In a tie brace tor concrete forms, the combination ot a pair of blocks, each formed with a cavity and with, a key slot at the outer end of the cavity` a tie rod connecting the blocks, and rods'arranged in alinemnt with the ends ot the tie rod and having hooks t their inner ends arranged to interlock in the cavityroi the block through the key slots by relative endwisc andr rotary movei'nent of the rods and the blocks, substantially as a nd for the purpose described.v

i'. ln a tie brace tor concrete forms, the

combination ot a form, a pair lot 4blocks bearingv against inner opposing faces of the form and each having an internal cavity formed with vkey slots' in the end Walls thereoy a tie iod'having*laterally turned hook shaped ends arranged to enter the key slots and interloclred with the ivalls of the cavities ot the blocks by relative endivise and rotary movements of the tie rod and the ibloclrs. pull rods extending through Lthe Walls of the form and having laterally turned hoolrs at its inner ends arranged to interlock in thev cavities of the blocks through the hey slots in the outer end ivalls ot the cavities ot the block by relative end-4 ivise and rotary movements of the blocks in the pull rods, the pull` rods being formed Y ith yhooks at their outer ends having their bills arranged substantially parallel to such rods` and lul-shaped Wedges arranged astride the bills ot the` last mentioned hooks rvwith` one inclined surface ot each Wedge bearing against the bend ot the contiguous and the intermediate or bach of the U-shaped forniation against the'iorm, substaiitially as and icor the purpose described.

ln testimony whereof, 1 have hereunto signed my naine, at Syracuse, in the ,county oi? Onondaga and State of NeuT Yorln this 30th day otNovember, .1920. i
