The. present invention relates to concrete forms, and aims to provide improvements in forms used for molding. curbs, curbs and gutters, walls, sidewalks, and the like,
Another object is the provision of novel means for connecting spaced form rails or side members to hold them in spaced relation in an efficient, simple, and-convenient manner.
A further object is the provision of novel means for maintaining theside rails or membersinalinemcnt endtoend, and for. joining them together in aconveni'ent, practical and eilicient manner.
A still further object is the --provision of means'for simultaneously, or with a sing-1e device, spacing theform rails or. side meim bers apart and joining the adjacent ends thereof; and a further object, inthisconnection, is the provision ofsuch a device adapt-- ed to accommodatea division plate.
Still another object is theprovision o fanadjustable division plate or. member which will accommodate the-form, 'rails'or side members when disposed at d-iiierent angles relatively to one another.
The invention alsohas; for anobject the provision or" :such improvements in; concreteforms which will .not only be practical, convenient and efficient, but whioh will also provide for economy-in manufacture. Y
\Yith, the/foregoing and other vobjectsin view, which will beapparent-as the description proceeds. the invention resides in the. construction and arrangement of parts, as hereinafter described. and claimed, it being understood that changes can be made within, the scope of what is hereina fter claimedwithout departing from v the spirit of theinvention.

similar forms may be 'used for molding walls,'side.wal ks, and similar structures, it being. understood thatthe side-rails vor members 1A of the form may be of different heights and nay be'spaced apart different distances according to thework to be done. The rails. or side members 1,4 arecomposed of sheet metal and. have .thewebs 15, form ing,the side walls-of themolpl, and said rails have the .outturn ed" tread and base flanges 16 andl'T, respectively-,at the upper and lower edgesiof the webs. The tread flanges 16 have the secondary downturned flanges 18, and the base flanges 17 havethe secondif rn d fla e 9-- In-orderto connect v mb r l l'r pa e. emeiea the iesired' distance, as..wellasto jointhe alining rails. end to, end connectinggand joint the opposite rails or yokes or arches 20 are provided. Each yoke comprises the upright bars or limbs 21 and a cross bar 22 overlapping and welded or otherwise secured to the upper end portions of the bars 21. When producing a straight V curb, that is, a curb whose sides are vertical,
. receive the dowels 23, in order that the yoke the bars 21 are vertical. extend through the bars 21 and are welded or otherwise made rigid with said bars, with the terminals of said pins or dowels projecting from the opposite sides of the yoke and arranged to be located between the base and tread flanges of the rails.
The 'yokes 20 are disposed between the adjacent ends of therails, and the rails are provided with means at their ends to the yokes so as to space the rails apart and aline them. Thus, the rails haveoutturned end flanges 24. These flanges 24 extend upwardly anddownwardly between the base and tread flanges and are preferably flush with the ends of the rails. Said flanges 24 are conveniently provided by welding or otherwise securing angle irons 25 to the webs 15 at the outer sides of the rails. The flanges 24 are provided with apertures 26 to and rails may be moved together into engagementlongitudinally of the form. It will be apparent that the yoke may be readily moved longitudinally of the i'orm into engagement with the flanges 24 of a pair of rails, after whiohthe next adjoining rails may be moved longitudinally into engagement with the yoke. The dowels or pins 23 will aline the rails at the opposite sides, and maintain themin accurate alinement,
and the yoke will also space the opposite rails apart the desired distance, according to the length of the cross bar 22. The yoke 20 thus serves as a spacer or cross connection,
between the side rails or forms, as well as providing a joint member to connect the rails end to end. 7
Each yoke 20 is also adapted to accommodate a division plate 27 which may be in serted downwardly between the bars or limbs. 21 of the yoke across the cross bar 22 which is offset to one side of the bars 21. The division plate 27 is of a width to move between the bars 21 with the edges of the division plate contacting with the inner or adjacent edgesof the bars 21. The bars 2 space the ends of the rails apart slightly so as to receive'and accommodate the" edges of the division plate 27 between the rails, as
seen in Fig. 2, This division plate may be used to divide the curb or other concrete structure, and may alsobe used as an end wall for the mold. The division plate pret erably projects above the yoke and has an aperture28 therein or other means above the yoke for convenience in withdrawin'gthe division plate from the mold or form.
Other division plates are provided to be Pins or dowels .23
disposed between the opposite rails or form members at different longitudinalpoints, and an adjustable division plate 29 is shown to be used for either, straight or battered curbs, with-the rails either vertical, as shown in Fig. 4, or with one rail vertical and the other inclined, as seen in Fig. 5, or both v division plate are formed adjacent to their outer oropposite side edges with sl ts extending upwardly from the lower ends of said sections, and formingdownwardly extending prongs that are adapted to extend downwardly at the outer sides of the webs 15 of the rails. I
In order to accomodate the division plate 29, the rails have apertures 34 in the tread flanges 16, which may be spaced longitudinally at desired intervals, such as every foot apart,'in order that the division plates may be spaced apart any number of feet desired.
The rails have slots 35 extending from the apertures 34 through the upper corners of the rails and down intothe webs 15. When applying a division plate to the rails the prongs 33are inserted downwardly through the corresponding apertures 34 so as topass down across the outer sides 0]": the rails and sections 30 move down and seat'in the slots 35, thereby supporting the division plate, and the prongs 33 assist in preventing the rails from spreading apart. The pivot 13 will permit the sections 30 of the division plate to tilt relatively to one another so that the division plate will accommodate the rails when vertical. as seen in Fig. .4, or when converging upwardly, as seen in Fig, The sections 30 have apertures 36 at theirupper ends for the engagement of means to conveniently withdraw the division plate of the? rails and concrete. lVhen using the slots 35, it is preferable to weld or otherwise secure reenforcing pieces 37 to the outer sides of the rail webs 15 below the slots 35 to and the other bar or limb 21 is inclined and 1 ill they have their upper ends secured to the cross bar 22 The bars 21 and 21 have the dowels 23 and the division plate 27 is insert-' able downwardly between the bar 21 and 21 the inner edge 21 of the bar QIL being preferably parallel with the bar 21" from the upper end of the bar 21 to a point intermediate the ends of said bar 21 It will be apparent that the yoke serves the same purpose as the yoke 20 hereinb'efore de scribed, excepting that the rails at one side are vertical while at the opposite side they are inclined for producing a battered curb.
Fig. 7 shows an adjustable yoke compris- 1 ing the bars or limbs 21 pivotally connected at their upper ends to the end portions of the cross bar 22 by means of pivot bolts 38 on which are disposed nut-s 39 whereby after the bars 21 have been adjusted to either vertical or inclined positions they may be clamped to the bar 22 by tightening the nuts 39. This type of yoke may be used for either straight or battered curbs, inasmuch as either bar or'limb 21 may be positioned vertically or inclined at different angles.
Fig. 8 illustrates the yoke of a curb and gutter form. Such form includes the outer rails or side members 14 to define the outer side of the curb, and the inner rails or side members 14 to define the inner or gutter side of the curb, the rails 14 being of greater height than the rails 14 with the upper edges of the rails in substantially the same horizontal plane. Accordingly, the yoke 20 has a long bar or limb 21 to be disposed between the rails 14 and a short bar or limb 21 to be disposed between the rails 14 The yoke has the cross bar 22 to which the bars 21 and 21 are secured, and-the division plate 27 is insertable downwardly in the yoke to be disposed between the adjacent ends of the rails. V
Fig. 9 shows an adjustable division plate 29 for use in the curb and gutter form, said division plate having overlapping sections 3O pivotally connected as at 31", so that said plate can be adjusted for both straight and battered curbs with either rail vertical or inclined. The prongs 33 and 33 of the two sections are of difi'erent lengths according to the heights of the lnner and outer rails, although the prong 33 may be of the same length as the short prong 33 if desired.
With the yokes or arches shown in Figs. 1. 6, 7 and 8, it will be'noted that the cross bar of each yoke is disposed above the rails or side members of the form, in order to be spaced above the surface of the concrete which is levelled off flush with'the upper tread flanges of the rails. This also permits the finishing tool to be moved under the cross bar of the yoke, sothat the yoke does not interfere with the finishing off of the concrete where the yoke is'located.
The form shown in Figs. 10 andll com- ,at opposite sides.
prises the relatively high back or outer rails 14 and the relatively low front or inner rails 14 on which are disposed the face rails 14 so that the back or outer side of the curb is vertical, and the lower portion of the front. or inner side ofthe curb also vertical.
The rails 14 are inclined toward the back rail so as to batter or bevel the face of the therein near the ends of the rails, and the ears 40 are also apertured, so that pins 42 may be inserted downwardly through the rails 14 in place against the pressure ex erted against said rails by the concrete when poured into the form. .The stop 43 is U- shaped so as to fit astride the edge of the The rails 14 and 14 are vertical The tread and base flanges of the rails 14 have apertures 41 yoke above the rails 14, and said stop carries a set screw 43 or other means to secure it on the yoke. I
\Vith such structure, the face rails l4 may be removed in order to finish the face of the curb before the concrete has completely hardened. This is readily accom plished by removing the pins 42 and stops 43 of the several yokes, and the rails 14 are then readily moved laterally away from thecurb. This exposes the face of the curb so that it may be readily finished. The back rails 14 and front rails 14 may remain in place until the concrete becomes solid. V
If desired, the stop 43 maybe welded or otherwise fastened rigidly to the yoke, and
the cars 40 are spaced sufficiently above the rails 14 so that said rails may be lifted and then moved transversely over the stop 43 when removing said rails.
Figs. 10 and 11 also showmeans for brac ing the form. A stake 44 is driven into the ground beyond the back rails, and a brace bar 45 is pivoted to said stake and is adapted' to overlap the upper outer corner portion of the yoke 20 Said bar 45 has a longitudinal slot 46 receiving a bolt 47 that is engaged through the yoke, and a't-ail nut 48 is threaded on said bolt for clamping the Jlo has been driven into brace bar and yoke together after the stake place. and adjustments made. i
F ig. 12 illustrates a form for producing a curb and gutter, with the face of the' curb battered or bevelled. The back rails 14c andufront rails 14 are connected with the yoke 20 in the same manner as hereinbefore described; The yoke 2O has a depending plate 21 betweenthe limbs thereof, and said plate is disposed between the adjacent ends of the face .rails 14*. The plate 21 has outstanding apertured ears 40 at opposite sides, and the tread flanges of the railsl4l have apertures 41. The webs of the rails 14* have outstanding apertured ears 49 be tween the upper and lower flanges, and the pins or rods 42 are inserted through the ears 40 apertures 41" and ears 49 to hold the face rails in place.
A stop or lug 48 is secured detachably on the plate 21* and has terminal portions 50 hearing against the rails 14: to hold said rails in place. The terminal portions 50 also extend under the ears 49 so as to sup port the rails l t Said stop or lug 43 is detached, after the rods or pins 42 are removed, so that the rails lt may be removed laterally without interference.
Fig. 18 shows a further modification for producing a curb integral with a street or road and having a face of compound curvature as shown. The yoke 20 has its outer limb inter-engaged with the ends of the back rails 14- the same as hereinbefore described. The face rails i l have their webs inclined and of compound curvature, so that the face of the curb is inclined and convexly curved at the top and concavely curved at the surface of the road or street. The rails 14* have the upstanding flanges 16 and 17 at their upper and lower edges, and said rails have the upstanding end flanges 2% that abut the broad inner limb of the yoke- Arms or angle irons 4:9 are secured to the end flanges 24 of the face rails/and are apertured to receive the pins or rods 42 that are inserted through the outstanding ears 4:0 of the yoke. A stop or lug -13 is secured to the yoke for the contact of the flanges 17*. The face rails 14, like the face rails 14F and 14*, may be readily removed laterally when the holding rods or pins between the yokes and face rails are removed. As shown, the lower armor angle iron 49 of eachrail'l lprojects beyond the flange 17 to seat on the stop or lug 43 so that the rail lt is supported from said stop or lug. Said stop or lug is detachably secured to the yoke by a set screw, so that the stop or lug may be removed when it'is desired to remove the rails or form members 14".
