O'HAJTEEN F Jcorr- INVENTOR ATTORNEY Patented Sept. 12, 1933 CONCRETE convent: FORM 'Chasteen Fr-Scott, OkIah Q ty 10m V v V Applicat ay 28', 1930; Serial N e This invention relates to, improvements 'in forms for molding concrete culverts. In moldingculverts ofysmall sizes,it-has been heretofore customary to construct the moldingv forms of 5 wood but this method of molding has been found tobe entirely unsatisfactory for several reasons. In the first place, the cost of labor expended in the construction of such forms is higlnand because ofthe nature of thematerial employed, namely wood, the forms after molding of thecul vert constitute practically a totalwaste. Furthermore, due to the wet nature of theconcrete, when introduced into a wooden form, the form is liable to become distorted and there, is liable to be a leakage of the concrete so that the com pleted culvert is not of the proper or uniform shape and is defective in one or more respects,

Therefore, the present invention has as its primary object to provide a form which may be readily set up for use and by the use of which a culvert of definite form and dimensionsmay be readily produced, the form, embodyingthe inven'-.

tion, being adapted to-be employed a great nume berfof times Without requiring any replacement or repair of its parts. 7 e r V Another 'obj ectxof the invention is; to provide a form for molding concrete culverts so constructed that its component partslmay be adjusted so j that a culvert-shaving any desired height, length 30, andwidth, to meet difierentrequirements, may

be molded'by the use, of the form, it beingpos sible, by the use of the fornnto mold culvertsof from twoto twelve feet in width. 7 1

Another objector thejinvention islto provide a molding form for molding culverts, which form may be, as stated above, employed, by aisimple.

' adjustment ofits parts,to mold culverts of diifere entdimensions and without the necessityof using any additional parts orany surplus braces or the 0 like.

l This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts tolbe hereinafter fully described, illustratedin' the accom- 4 panyingdrawings and. specifically pointed out in the appended claims;

and 6, sothat the length of the, side walls may be increased by the connection to these sections of other corresponding sections comprising an sired, a pair of the wing wall units 3 maybe connected with this end structure,'as well as at the left hand end-as shown in Figureg2.

The core unit 2 comprises side walls which are indicated in general by the numeral 12 and each'of these side walls comprises a lower s ec-,-

tion 13 in the formoi a sheet ironplate,-and

an 'upper section 14 likewisein the form or" a sheet iron plate, the sections being assembled "edge to edgeand channel irons 15 being bolted,

asindicated by'the numeral 16, to the inner sides of the sections 13 and 14 to relatively brace and connect the same The upper edges of the the upperedges ofthe flanges 17 upon the wall sections 14, and preferably this topv plate will be formed in two sections, so aslto effect economy in the manufacture of the combined parts ofvthe side walls, and thesaid top plate '20, the sections of the top plate 20 at their outer, edges are securedby bolts 21 to the angle 'bars'19, and

kat their meeting edgesbyrbolts 21 which are likewisesecured through the said'bars 19.

A plate 22 .is boltedatone vertical edge to each .side' wall 1 {as indicatedby the numeral 23 and bolted to. the, other edgeof the plate, 22 is N vthe flanged edge 2&1 of a vertically disposed plate 25 which constitutes a part of 'a respective one of theflwing wall extensions of 'the'form.;-.- The side walls of each'iwing jform are indicated by lthe numeral 26'ahd' byfreferience to Figures 2, .4 and 5 of the drawings, it will beseenthat each side wall comprises, in addition ,to'theplate 25, ' otherplates 27, 28 a'nd 29, ,the plate 27 being .of oblong rectangular form and. the plates 28 andf.29.having inclined edges indicated by the numerals 30 and-3'1 respectively, which are brought intoralinement when the plates are asspective plate 25; Both oftheside walls of each wing unit are of thehsame constructionjand in the instance of the inner side wall of eachwing a plate 3,2,fcorresponding to the plate 2 5, is sej curedat one vertical margin to the side walls of the respective wing unit,

The. wing units, .as will be evidentbyreference .to Figure 1, extend in diverging relation to each other, at any desired angle, and the side walls thereof; are braced at their outer ends by spacing means which comprise a plate 33 of a width equal to the spacing of the adjacent side of the walls of the wing, and angle bars 34 which are secured to the said plate 33 and to the outer ends 'of the lower sidewall section 2'7 by means of bolts 35. Angle irons "36 are secured to the upper edges 38 and 31 of each of the sections 28 and 29 andserve'torelativelybrace these sections, and channel bars 37 are bolted as at38 to the outer sides of the sections 2! and 28 of the side walls of each wing unit, and relatively brace the said sections, and atthat end of each side section of the mold form with which the respective wing unit is connected, there is provided 'asection 39 which is in the form of a sheet iron plate. or substantially oblong rectangular, form and one vertical edge-,oi which is-provided with bolt openings 40 whereby the "said edge portion may be secured to the angular flange 24 of the section 25, and this section 39 occupies the same-plane as thecorresponding side wall of the mold frame and the section is securedat its oppositevertical'marg'in by bolts 41 which are passed through the openings 40' and the correspondingopenings in the flange 24, and this section 391s provided at' its upper and inner corner with an outstanding flange l2 provided with boltopenings- 43'. The mold form 1 and the core 2 are connected, with the core 2 preferably centered with respect to the form, by means of bolts44 which are secured through the side wallsof the form 1 and through the side walls 13 of the core 2, these bolts being passed through the channel iron bars at every intersection'of the said bars and plates, and

between thebolts 8 that'hold' the plates of the "channel irons.

1n order-that thewalls ofthe mold form 1 may be braced and preferably spaced with respect to each other at the end thereof. from which the wing sections 3 extend, bracing units, indicated in general by the numeral 45 are provided and each of these units comprises a pair of oblong rectangular plates 46 which aremounted'at their ends upon polygonal plates 47 which arefshown in detail'in Figure '7 of the drawings, and'oneof the plates46 is provided along its lower'edge with an angularly extending-flange 48'which is of less length than the plate and which is provided with a-downwardly, right angularly turned extension 49 formed withb'olt openings 50. is likewise formed near its-upper edge with a series of bolt openings 51 and the other plate 46, which, instead'of the flange 48'and its extension 49 is provided' with a depending portion-52 oc-. cupying at common, plane therewith, is provided Witha series of boltopenings 53 near its upper edgeand the-series of bolt 'openingsf54 near the lower-edge of its extension 52, the extension 52 being 'of less length than the plate of which it, sembled and secured at their inner vertical marcompnses part a gins to the forward vertical margins of the re- Plates 55 are arranged in upright position be- The plate 46 tween the projecting ends of the plates 46 and l angle plates 56 are disposed-against the outer sideof each plate'55 and secured at their wings ,which' contact the plate 55 by rivets 57 to' the said plate, their other wings being formed with bolt openings 58 throughwhich'the bolts 59 are secured to anchor'the angle plates 56 to'the ends 'of the plates 46. Near the, edges of the riveted wings of each member 56 there is arranged a bracket member 60 having an outstanding lower end 61 through which a bolt 62 is s'ecured,-the

bolt fitting" also through an opening 63 formed in the respective'onejof the polygonal plates 47.

Each Plate 47 is e i c redioy a bolt sentroofing nails,.so that when the form is to be-disted'through an opening 65 therein and through .a horizontalflange of a bracket memberfifi which is riveted to the plate 46 which is providedwith the portion 52. An angle iron bar 67 is secured by bolts 68 which fit therethrough and through From the foregoing description of the invention it will be evident that the side walls of the mold frame may bespaced apart any desired distance by the employment of the connecting and bracing units 460i different lengths, as previously stated and the side walls of the mold form may be made of different lengths by suitably proportioning the plate sections 4, '5 and 6 thereof as.

regards their length or, adding to these sections, shortersections whichrnay be secured in place by bolts passing through the openings 9.

It will be understood of course that instead of channel irons such as those indicated by the numerals 7, 15 and 37, Woodpieces, substantially four inches square in cross section, may be employed, and this willpermit of 'the use either of the bolts 44 or tie wires, wherever desired, and in such a construction, the plates which are braced and connected by the channel iron may be secured in place to the wood pieces by-the mantled, the plates will constitute means for pulling the nails by the use of a wrecking bar behind the wood pieces. i a .What I claim isy 1.
