.. CONCRETE FORM. e

` y lApplication filed December The-present invention relates'to concrete forms, "and more' especially curb forms or` molds, it being the object of the yinvention to provide' a novel and improved concrete formv for buildinfr a concrete road or slab I V C: withan integral curb.

lAnother Objectis the provision of novel means for mountingor supporting one rail! orjform member on another rail or lform membemsuchV Yas when Vplacing, a curb delining rail Orfform member fon railA or form member usedvto definej'theside `of the ioad or slab. f p Y -A further objectisithe provision ofnovel means for adjustablyisupporting and bracing the face rail or form member that is Vused to define the face of the curb', in order that such rail or form member may be adjusted to produce curbs of different. Widths and with faces 'either vertical or inclined. f

1Witlithe foregoing and other objects in view, which vwillbe apparent as thedescription proceeds, the invention-resides in -the construction and arrangement of parts, -as hereinafter described and cla1med`,"1t being understood that changes eanbe madewithin thescope of'wha't is claimed without departing from the spirit of the invention.

vThe invention is illustrated'in thel accompanyingdrawing;whereini y Y F'gure 1 is a cross section of theffrails or form` members showing the improved 4devices applied thereto. V f f Fig. 2 is an Outsideview of the'form. I In accordance with the usual practice when building a concrete road or similar surfacing structure, the concrete is poured, struck-ofi", tamped and finished between side :form members or rails which define the sides of the slab. The. rails at one side vare indi:

cated at 11 which define the side of the Each rail has the vertical web 11, and the outturned `tread and base flanges 13 yand-14 provided with the sec-v are 8,*1925. Seria1 No. 74,018:

membersv17 are seated on the' rails 1,1,an'd

the upper and lower ouitturned flanges 18 and 19 pijovided with the downturnedand upturned secrinclary anges r20'- and 21, respectively. Inner or face curb rails or form 'members complement the rails 17 and, like,V the, rails 17, are of `C.shaped cross section,

each'rail 22 'having the web'23andthe upper and lowerilanges 24 and 25 :provided l'with the secondary llanges 26 and 27 respectively. `The rails are disposed end to'end asfusual,

being rolled or Otherwise formed' Yfrom heavy sheetfmetal.` Y v w Inorder to support and hold the upperrails 17 in place on the lowerrails 11 sup. porting devices are used at suitable inter-y /each Vrail 17 has the vertical web 17rand vals along the foi-m, one of lwhich is shown inFigs. 1 and 2. f Thissupporting device comprises a plate or other suitable memberI VQSveXtending vertically across the. flanges. l 15 and 21 of the rails 11 and 17, and formed atits upper endwith a head 29 Ato bear upt. i

wardly against the flange `18 betweenqthe flange-*2O and web,17 of the rail .17, the

vupper terminal of the plate 28 being bent Vinwardly and downwardly as seen in Fig.

A secondary plate 30 isV securedtothe plate 28 near the lower 'endthereofand at theinner lside of saidfplate 28, with a spacer 31-between the'plates`28. andr30, and the plate 30 has an inwardly and downwardly lbent portion 32, similar tothe portion 29,.to engage under the' flangev 13 Vbetween the The yspacer 31 spaces the plate 30 inwardly from 'the plate 28s@ yas to accommodate thellange 15. The lower end portion of the plate 28 flange 15 and webY 11 of therail 11.

is bent outwardly at an obtuse angle, as.y at

'33, and a cam plate 34 is pivoted, as at 35,

on theVV portion 33 and its-lower or free end is ormedwith afcurved or cam edgeA 36 .to seat lin the corner between the base flange 14 Y l and/secondary flange 16 of the rail 11.r z Y In applying the supporting device,fthe

plate or -member 30 is readily insertedV underkk the tread flange 13 of therail 11, when the," plate 34 isswung upwardly, and said cam.

plate 34 is then readilyl swung downwardly so as to seat on the base ilange 14 by .cam action, andV said plate 34 may be driven tightly into -place, thereby clamping thie plate or member 30 tightly up against the tread flange 13, and securely holding. the

plate 28 in upstanding position. The. rail -17 not only seats on the rail 11 but is parlll the flanges of a lower form rail and havingay portion for holding in place an upper form rail. Y Y r 2.
