culvert form may be collapsed for the purfor-a circular culvert. tron ofa mold for a semi-circular culvert.
pose of being removed from the culvert after the same is set and hard.
i A further object of the invention is to provide im roved means for making the facings or shou ders at the ends of the culverts or plpe. 1
Various forms of the invention are hereinafter described and are illustrated in the accompanying drawings, in which 4 Figure 1 is an end elevation of the mold,
Fig. 2 is an end eleva- Fig. 3 is a section on the line 3? of Fig. 1'. Fig. 4 is a top plan view of one end of the mold. Figs. 5 and 6 are details in side and end elevation of a modification.
The mold or pipe form proper is made of a series of staves or sections indicated at 2'eX- tending lengthwise. These are supported at their ends, or at the ends of the culvert,-
upon walls consisting" of lower and upper planks 1 and 1 fastened together by cleats 1 a sufiicient number of contractible ribs or to-form upper and lower sections which, with a circular culvert, meet at the middle line, and are fastened together by means of rods 4 which hook into plates 5 at the bottom and which extend through plates7 at the top, and drawn tight by nuts 6 on the threaded ends of the rods. The walls so formed support the staves or sections 2 at the ends thereof, and also form the outer part of the mold for the flashings or shoulders at the ends of the culvert. The inner or inside walls for molding said flashings are formed by boards 8 which are spaced from the walls 1 and 1 and are held at proper distance by bolts 9 and vertical ieces 1O therebetween.
culvert the interior frame consists of a seg' In the circular mental part 3 to theends of which are hinge at a, the segmental sections 3f, which are ar .rangedto swing inwardly, as shown in dotted hnes m Fig. 1, their meeting ends, however, being halved and lapped and provided with below the center of the circle, so that when the frame is contracted it may readily be lifted and removed. 1
' In constructing a semi-circular culvert, as indicated inFig. 2,. the two curved sections 3 are used, hinged at their lower ends to the outer ends of rods 3, the inner ends of which are connected'by a turn-buckle 3, and the opening in the end walls 1 andl is shaped to correspond. This form may becollapsed by removinggfhe -pin 3 and then taking up the turn-buc e, thereby drawing the side ieces together and allowing the frame to e removed and the staves to collapse or fall inwardly and to be conveniently removed." Two of the staves, at the crown of the culvert, are preferably rovided with projecting plates 2 which will ap any crack incident to shrinlia e of the wood forming the staves. These p ates la the beveled crown stave 2 In the mod' ed form shown in Figs. 5 and 6 the segments 3 are hinged to the ends of the lapped radius bars 3 and 3 connected by a pin 3, and which telescope or slide one upon the other to lengthen or shorten the a pin 3? which may be inserted through holes made to receive it, to support said parts in expanded position. Phe hinge points a are same, and consequently, when the in is removed, may be drawn together to re ease theparts from the staves forming the mold. A
In use, to construct a culvert, the lower end walls 1 at each end are set or attached at proper distance apart, and the staves 2 of the lower half of the circumference are laid across. The collapsible frames 3 are then set within the form, after which the remainder of the cleats are laid across-to complete the circle. The upper end walls 1 are then put in place and the rods 4 connected and tightened, thereby holding the walls together and also clamping the staves in place. The inside boards 8 are then added. The concrete is then placed around the formin proper shape to form-the tube and the shoulder at the ends thereof, after which the gravel and earth maybe filled in and the concrete allowed to. set. The whole form maythen be readily collapsed by loosening the frames 3 and 3, permitting the staves to i fall in. The end wall sections can then be' mg evioe at their ends,,adapted to permit @9 62 sugl reamers co y 2, A supporting frame for collapsiblemolds, comprising segmental pieces having a joint at their ends permitting extension or 15 contraction, and a contractible bar conneot= in the opposite ends of said pieces.
