Application sied August 8, 1910. Serial No. 576,044.

To all whom it may conce/n:

Be it known that l. Maarn* CARROLL. a citizen ot' the United States. residing at Kansas City. in the county of Jackson and State of Missouri7 have invented certain new and useful Improvements in Molds, of which the following is a speciticatioln My invention relates to niolds.

It relates particularly to a clamping mechanism by which the members of a mold may De releasably held together, and ist particularly adapted for use in connection with molds for making concrete columns.

The novel ieatures of my invention are hereinafter more fully described and claimed.

In the accompanying drawings illustrative of the preferred form of my invention, Figure 1 is an elevation, showing the clamping mechanism mounted on a column mold. Fig. 2 is a plan View, the mold members being shown in dotted lines. 'Fig'. 3 is a vertical section on the dotted line a-hot Fig. Q. Fig. 4 is a vertical section on the dotted line c-cZ of Fig. 2. Fig. 5 is a perspective view of one of the corner blocks.

Similar reference characters denote 'similar parts.

1 denotes the mold members comprising vertical planks disposed edge to edge to form -a mold rectangular in cross section. Two right angled clamping blocks 2 are provided. The two blocks are alike so that a description of one. will suiiice for each. Each block 2 is provided on its upper side with a projection 3, preferably of rectangular form and having preferably in its two outer sides recesses ldisposed horizontally atright angles to each other. The block 2 may also have two projections 5 and 6 which are separated from the projection 3 by two grooves 7 and '8 disposed at right angles to each other and adapted to have lie therein horizontal clamping bars 9 which are pivoted respectively to two similar clamping bars 9 which afreadapted to lie in the grooves 7 and `8 of the other block Each bar 9 is provided with a longitudinal rows of holes 10 adapted to receive there in vertical bolts 11 'which serve as abutments against which may bear respectively four wedges 12, each comprising a fiat horizontal plate, preferably provided with `an obliquely disposed slot- 14 through which extends the serves to hold the wedge against the adjaadjacentboltl 11 the head of whiolr cntbar 9. The other ends of the bolts 11 may have mounted on them nuts 15 which bear against the under sides ot the bars 9.' The inner straightedges ot the wedges 12 arc adapted for insertion in the recesses 4C of the projections 3, thereby holding the wedges and the bars 9 against vertical movement relative to the blocks 2. Each block 2 may have one or more downwardly extending projectionsl having horizontal holes 17 therethrough for the insertion of nails 18, or similar-devices, adapted to be driven into the mold members 1 for detachably temporarily supporting the blocks 2 until the wedges 12 have projections 5 and 'serve to support the inner edges of thewedges 12 in the same manner in which the projections 3 support said wedges. 4

in operating my invention, the mold members 1 having been assembled in the proper vertical positions, the blocks 2 are mounted thereon at diagonally yopposite corners of the mold vto which they are secured by nails 18 extending through the projections 16 into the members 1. The clamping bars 9 are then made to respectively embracethe four sides of the mold, and are mounted in` the grooves 7 and 8 between the projections 3 andthe mold members 1, the two bars ot one pair crossing. the two members' of the other pair at right angles. The wedges 1.2 are then mounted on the tops of the bars and disposed with their edges in the recesses t. The bolts 11 are then passed through the slots 14 .of the wedges and also through theadjacent holes 10. The nuts lare then mounted on the bolts'll below the bars; 9, after which the wedges are driven to tighten them aga-inst the bolts 11 and projections 3, Sand 6, thus tightly clamping the mold members 1 together. To remove the clampmg bars from the mold, the operation just4 described is reversed.

been tightened. The

My invention may be subjected to many modifications, within the scope of the appended claims, without departing from 1ts spirit.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

l. In a` mold, a device for clamping one si e of a mold, a block posite side of the mold7 and having a projection having a recess in its outer side, a clamping bar secured to said device and for clamping the topi.'

adopted 'to extend eci'osf, lie conch between the projection eiid the mold, sii abutment adjustable length Wise of seid clamping her,

:oid e 1Wedge insertihle in seid recess and adopted to heer against seid block end seid ohutment.

2. iii si mold, e` devi for clamping one side of e mold, e black for demping the opposite side of the mold and having o piojectioo provided with a recess in its coter side, s. clamping bei* secured to the device and adopted to extend across said boolr hetween the projection and the mold and heving e longitudinal roe:y of holes, a Wedglfe im itihie in seid recess and having e slot posed ohliqoely to the portion disposed in seid recess, and e bolt ioscrtible through seid slot and through any of seid holes.

3. In a meid, s pair oit devices for clamping adjacent sides respectively of a recteugiiler mold, :i corner block for clamping; the other two sides and having a projection having two recesses disposed et right ongles to each other iii its tivo outei17 sides, two clamping hers secured respectively 'to seid devices and adapted to extend et right :to gies across each other between the mold and seid projection, two wedges for insertion res\ectively iii seid reces. eiid tivo shoe ments for respectively securing the Wedges to seid hers' and respectively adjustable lengthwise of said hars.

et. In e mold, e pair et devices to? elempiiig adjacent sides respectively of a rectas-- guiar mold, i corner block for clamping the other two sides end having :i projection heviisg tivo recesses iii tivo octetY sides7 two clamping hers secured to said two devices respectively und adopted to extend et right :Regles across each other between 'the projection mid the mold and having each e longi tudiiiel row of holes, two Wedges adopted to he disposed respectively iii seid recesses end to bear against said projection, and two bolts respectively insertible in the holes of seid two rows and adopted to here the Wedges heer against them.

In a mold, e pair of devices 'tor clamp ing adjacentsides respectively oi a reetanguiar mold, e comer 'block :for clamping the other 'two sides end having o.' pi'ojectioio having two recesses in its outer adjacent sides, two ciampinghors secu-red respectively to said devices :mtl adopted to extend at right angles across each other between the yprojection and the mold, the here having each e longitudinal row of holes, two Wedges inseitihie respectively in seid recesses and having each e slot .disposed obliquely to the port disposed iii-seid recess, and two bolts iiiseitibierespectively, through seid slots and through the holes in seid 'two hars forv securing the 'Wedges to said hers :md for supporting said Wedges.
