CURB AND GUTTER FORM.

Application filed. January 31, 1927. Serial Ito 164,820.

The present invention relates to concrete forms or molds, and more particularly curb and gutter forms, it being the primary object of the invention to provide a novel and .improved curb and gutter form for conveniently producing a curb integral with a gutter or a road slab.

Another object is the provision of a curb and gutter form comprising a novel assemblage of the component elements, and having novel features of construction. v

With the foregoing and other objects in View, which will be apparent as the description proceeds, the invention residesin the construction and arrangement of parts. as hereinafter described and claimed, it being understood that changes can be made with in the scope of what is claimed. without departing from the spirit of the invention.

'The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a fragmentary perspective view of a curb and gutter form embodying the improvements. r i Fig. 2 is a cross section adjacent to the template or division plate showing the improved holding device in elevation.

Fig. 11 is a cross section of thetread portions of the type or back rail shown in Figs. 6 and 8. with a wheel of a carriage, bridge or finishing machine thereon.

Fig. 12 is a cross section of superposed back rails.

i The form shown in Figs. 1, 2 and 3 comprises the back rail 7, the front rail 8 and face rail 9 of sheet metal. The

rails

7 and 8 are of C-shaped cross section. The rail 7 comprises the vertical web 10, upper'flange 11 having a depending secondary flange or lip 12, and lower or base flange 13 having the upturned secondary flange or lip 14. The front rail 8. which is of less height than the back rail, comprises the vertical web 15, upper flange 16 having the secondary downturned flange or lip 17, and lower or base flange 18 having the secondary upturned flange or lip 19. The face rail 9 has the web 20 and the upper flange 21 provided with the depending secondary flange or li 22. The lower edge portion of the rail 9 is bent. as at 23, to conform to the contour between the face of the curb and the surface of the gutter.

The rails are of suitable length and are laid end to end. as wellknown in the art, and at suitable intervals longitudinally of the form, templates or division plates 24 are used, only one of such plates being shown.

The plate 24 is disposed transversely of the rails in a vertical plane and has the curb portion 25 disposed between the

rails

7 and 9, and the gutter portion 26 extending from below the rail 9 to the rail 8. The portion 25 has an edge 27 conforming to the face of the curb, and the upper edge 28 of the portion 26 conforms to the surface of the gutter. and the corner between the

edges

27 and 28 is rounded similarly to the lower edge portion 23 of the rail 9, the web 20 of said rail 9 bearing against the edge 27. The plate 24 is formed with a depending arm 29 beyond the portion 25 and a downwardly opening slot 30 between the arm 29 and portion 25, and the plate 24 is provided at its opposite end witha depending arm 31 and a downwardly opening slot 32 between said arm 31 and portion26. The

flanges

11 and 16 have openings 33 for the downward passage of the arms 29 and 31', and the

rails

7 and 8 have slots 34 extending downwardly from the openings 33 into the

webs

10 and 15. respectively, to receive the portions of the plate 2/1 uniting the

arms

29 and 31 with the body of said plate. The

arms

29 and 31 thus extend downwardly at those sides of the webs of the

rails

7 and 8 at the exterior of the form, with the rail webs in the

slots

30 and 32, thereby holding the

rails

7 and 8 in place. The plate '24 spaces the rails 7 and'8 apart the desired distance, and also maintains said rails in vertical position. The plate 24c has apertures 25 at the upper ends of the arms 29 stud or pin 46" secured to the member 36 to pass through an aperture 47 in the upper flange of the rail 7, with a sleeve or enlargement 44" on the stud to form a chair spacmg and supporting the member 36 from the rail 7, as well as holding said member in position relatively to said rail.

F ig, 6 illustrates a template or division plate 24 extending from the back rail 7 under the face rail 9 to the ed 'e of a vreviously completed road slab 52, without using a front rail, such as previously suggested herein. The outer endof the plate 24 has a depending arm 29 'to engage the rail 7, and the plate 24 has an upstanding portion at its inner end provided with the hook slot 51?. The member or bar 36* located above theplate 24 and. extending across the rails has a depending plate or' hanger 41 between its ends notched to engage over the

upstanding flanges

21 and 23 of the rail 9, and bolts 53 or other means a cam is pivoted between and to the ter- 2 plate 24 andback rail.

minals of the stirrup to bear on the inner end portion of the member 36, in order to drawsaid member and plate 24 toward one another at the inner end thereof, for clamping the rails and plate 24 together. The cam 55 has an arm or handle 56 for 'convenience in swinging the cam, and said arm bears against the inner end of the member 36, as seen in Fig. 6, to lock the parts together. By swinging the arm upwardly to release the cam 55, thestirrup 54 is readily removed from the plate 24. and the member 36" with its plate 41 and the hook bolt 87 may bereadily removed from the It is then possible to finish off the surface of the curb and gutter and the upper edge of the plate 24 will serve as a template to guide a screed board or member used or finishing the surface of the curb and gutter.

Figs. 8, 9 and 1.0 illustrate a template'or division bar'24 which, as shown, is in the form of a compound curve, but which may be of any other suitable shape according to the contour of the curb to be formed, and said bar 24 does not extend to the sub-base as do the

plates

24, 24, 24 and 24 here- 7 inbefore described, but only extends a slightdistancebelow the surface of the curb. The rail 7 and its flange 11 member 36' and its plate 41*, hook bolt 37 and face rail 9 are. substantially the same as shown in Fig.

i 6, and the outer end portion of the bar24 has a short depending arm or portion 29" to engage down through the aperture .53 in the flange .11 of the back rail, with an aperture to facilitate lifting the outer end of the bar from the back rail. The inner end of the bar 24 is welded or otherwise secured to a stake 31* which is driven into the sub-base to support the inner end of said bar. Said stake projects above the inner end of the bar and has an aperture 51 for the engagement of the hook at the lower end of a bolt or rod 39" that engages through the inner end portion of the member 36.

With the form construction shown 8, 9 and 10, the road slab 52 may be completed up to the back rail 7 and the stakes 31 are then driven down through the slab while the same is still plastic, the outer ends of the bars 24 being engaged in the openin Figs.

ings o1" apertures 33* of the back rail 7".

The face rail 9 is then applied, being of a shape to fit and seat on the bars 24', as

seen in Fig. 8, and the member 36 is then attached to the back rail. and stakes, to clamp the parts together. Additional materialmay then be poured between the back and face rails so as to form the curb, which amalgamates with the slab, to form an integral curb and road slab. After the material has set sutliciently, the face rail 9 ma me ren'ioved by detaching the hook bolts 37" and 39" from the back rail and stakes, respectively. The surface of the curb may then be finished off conveniently by sliding a longitudinal screed board or member 58 on the bars 24, as seen in 10, said bars serving as templates. Then, by lifting the out r ends of the bars 24 from the back rail and pulling the stakes 31", the bars and stakes are removed, after which the slots left in the concrete may be finished. off or filled in.

The upper flange 11 of the back rail as seen in Fig. 6 and the upper flange 11 of theback rail as shown in Figs. 8, 9, 10 and 11, are arrangedon a bevel or slope away from the webof the rail, so as to provide a single line of contact'for a wheel 59 travelling on the rail. This provides a clean contact between the back rails at opposite sides of a road under construction and the "Wheels of carriages travelling on said rails,

it being the practice to run bridges, finishing machines, and the like, on the rails during the building and completlon of the road. It

. will be noted that sand, gravel and other materials which may fall on the upper flange of the back rail will be shed outwardly of the rail, so as not to accumulate thereon, and the wheels of the carriages will thus have a perfect contact with the-rails along lines directly above the webs of the rails, as seen in Fig, 11. The carriage will therefore be guided along a true line, which is especially Ill! ' other :particles ito accumulate or lay on the tread flanges, so that wheels of finishing machines or other carriages travelling on the rails, in passing over the particles thereon, will vibrate the machine. However, with the sloping tread flanges .as seen in Figs.

(5 to 11, inclusive, the particles will roll or slide-oft" the tread flanges. It will. be noted that the wheels contacting with the rails along lines immediately :above the webs of the irailswill transmit the weight. and pressure directlydownward inthe planes of the rail webs, in order to prevent-anytendency for the weight'and pressure of the machine 'or carriage .to bend the tread flanges of strains, although they stiti'en and reinforce the :rails.

When using the forms shown in Figs. 6, 8, 9 and '10, th'e'back rail 7, as seen in Fig. 12, may be of the height'ot the curb, and maybe seated on and secured to a rail 7 that is employed for .theconstruction oi the ."oa dslab. Thus, the rail 7 is of the height or thickness-of the road slab, and after the road slabis completed the back rail 7 may be seated and secured on. the rail 7 for completing the curb. If this construction is used in the form shown in Fig. 6, the rail 7 lisdirst used to define-the edge 01 the slab 52 and is then set outwardly to required distance away from the slab into the line of the rail 7 as seen in Fig. 6, but the

rails

7 and 7 are especially intended for the form shown in Figs, 8. Sand 10.

As shownin Fig.6, the stirrup or'member 54- is connected directly with the portion ot-the plate 24, and said stirrup may also 1e usedwith the'construction shown in Fi gs. 1 to 5, inclusive, and in Figs. :1-5 the hook boltor member 39 is connected with the template-or division plate through the medium of the front rail, although said hook bolts may be connected directly with the portions 50 ot the templates or division plates. As seen in Fig.Sthehookboltor member 39" is connected with the template or bar 24: through .the medium of the upper portion 'rt the stake. and'ezch. l orin the inner end portion of the template has an upstanding portion with an aperture or slot for the engagemento'tthehook bolt orother member oi? the device which clamps the back and face l'tllSiUltl template together.
