1 Claim. (Cl. 25--118) This invention relates to an adjustable curb hood for mold forms, and particularly to an adjustable hood to be mounted on a mold form for constructing a curb in relation to an inlet or other aperture adjacent to the edge of a street or a roadway.
In road constructions, it is customary to provide a plurality of inlets in the road, with the inlets being partially on the traveled road and partially under the curb or edge liner of the road. It has heretofore been practiced, as shown in my prior patent, No. 2,650,410, to provide inlet mold forms having hoods rigidly attached thereto so that the inlet mold and the curb adjacent thereto may be cast as a single concrete piece. Diificulty has been encountered in utilizing such mold forms on sloping terrain, as the fixed curb hood has not properly conformed to the slope of the curb to be applied. Also, it has been proposed to cast the inlet box first, and then, to provide an attachable mold and cast the curb at a later period. This, however, is undesirable in that the curb is then not a unitary portion of the mold that has been cast.
in the construction according to the present invention, an adjustable curb hood is provided for attachment on the usual mold form so that the curb hood may be adjusted to any desired inclination and properly attached to and mounted on the mold form so that the curb and the mold may be cast as a single unitary block.
in a construction according to the invention, a plate is constructed by bending along transverse lines to provide a back panel which will overlie a portion of the mold form and a sloping top form to provide the undercut of the curb and an attaching ledge to secure to the front curb mold of the usual construction. End members are provided under the angulated top piece and adjustably connected to the back panel so that the panel ends may be vertically disposed regardless of the inclination of the back panel and laterally extending end members are secured on the end pieces so that the curb may be continuous past the inlet opening.
It is accordingly an object of the invention to provide an improved curb hood form.
It is a further object of the invention to provide a curb hood form which may be adjustably mounted on a mold form.
It is a further object of the invention to provide a hood form which may be adjusted to various angles of inclination and rigidly connected together.
Other objects and many of the attendant advantages of the present invention will be apparent from the following detailed description taken in conjunction with the accompanying drawing in which:
Figure l is a vertical sectional elevation through a mold form showing the improved curb hood in position thereon;
Figure 2 is a perspective view of the curb hood form;
Figure 3 is a top plan view, with a portion broken away and in section of the curb hood form and showing the construction thereof;
a 2,817,137 lee Patented Dec. 24, 1957 Figure 4 is a perspective view of the main plate forming the back and top panel and attaching legs;
Figure 5 is a perspective view of an end member for closing the ends of the panels;
Figure 6 is a perspective view of a channel form member for spanning the space between inner and outer portions of the mold form;
Figure 7 is a top plan view of the finished mold, as made in the mold form with parts broken away; and
Figure 8 is a vertical sectional elevation through the finished mold with the mold form removed.
In the exemplary embodiment according to the invention, a conventional mold form according to my prior patent is provided with an outer form 10 and an inner form 12, with the outer form 10 being constructed of a plurality of channel-shaped members 14 connected together to provide a back wall and front wall of any desired height. The inner mold member 12 is suspended within the outer mold member 10 by means of crossmembers 16 and 18 seated in suitable bearing slots 20 and 22. of the outer mold form 10. As is shown in my prior patent, the transverse member 18 further serves the function of being a mold form for the construction of a curb and preferably a chamfer strip 24 is placed in the space between the back wall of the mold form 10 and the transverse piece 18 so that the curb will be provided with a suitable chamfer to prevent readily breaking away the corners thereof.
A hood form according to the present invention comprises a back panel 30 and a sloping top panel 32 together with an attaching ledge 34. Preferably, the panels 30, 32 and 34 are constructed from a single plate member by providing the angle bends 36 and 38. Although, obviously, if desired, the panel members could be separate and welded or otherwise secured together.
The attaching ledge 34 will be provided with a plurality of apertures 40 so that the hood form may be readily attached to the transverse supporting member 18 by any suitable means, such as the bolts 42.
The back panel 30 is provided with a plurality of vertically disposed apertures 46 for adjustably connecting the back panel 30 to the inner mold form 12 by any suitable fasteners, such as the bolts 48. The ends 50 and 52 of the back panel 30 have been cut away to provide a constantly decreasing length of the panel from the junction 36 to the bottom of the panel.
A pair of end members 56 and 58 are provided, having a width substantially equal to the vertical distance from the front edge of the attaching member 34 to the panel 30. The top ends of the panels 56 and 58 are cut away to provide a sloping portion 60 which will conform substantially to the slope of the panel 32 so that the ends of the end members 56 and 58 will abut against the sloping panel when the back of the end members is in contact with the panels 30. The top is also provided with a portion 62 adapted to abut against the bottom of the attaching member 34 so that the end members completely fill the space under the top panel 32 and the attaching member 34. The end member 56 is provided with an inturned flange member 64 and the end member 58 is provided with an inturned flange member 66. The members 64 and 66 extend inwardly from the end members and overlie or overlap a portion of the back panel 30, and are in preferably direct contact therewith. The flange members 64 and 66 are provided with suitable apertures 68 for receiving a bolt 70 which will be received in a longitudinally extending aperture 72 or 74 in the panel 30 so that the end members 56 and 58 may be angularly adjustable with respect to the panel 30. The sloping portion 60 of the top of the end members is provided with an inturned member, herein shown as a channel member 74 rigidly attached to the end members and having an inturned flange portion 76. Obviously, instead of using a channel member, a portion of the metal of the plate forming the end members could be turned in to provide the inturned member 76.
The inturned member 76 is provided with an aperture 78 for receiving a bolt 80 which is received in a longitudinally extending slot 82 or 84 of the sloping panels 32.
In order to span the space between the inner mold form 12 and the outer mold form 10, suitable wings 86 and 88 will be provided. The wings 86 and 88 are herein shown as channel members having a bight portion 90 comprised of a substantially flat plate and side members 92 and 94 substantially in the form of angle members welded to the bight portion 90. The side members 92 will be provided with apertures 96 for receiving bolts 98 for fastening the device to the end member or to the outer mold form 10, as may be desired.
' In the operation of the device according to the invention, the outer mold form 10 will be placed in position, after which the inner mold form 12 will be supported therein by means of the cross-members 16 and 18 and the hood member will be applied thereto with the panel 30 overlapping the back of the inner mold form 12 and extending thereabout and the panel 30 will be adjusted so that the panel 32 will be at the desired inclination to provide the underlip 100 of a curb 102. The end members will then be adjusted so that they are in vertical position so that the wing members 86 and 88 will be rigidly attached to the outer mold form 10 to provide a suitable curb construction. It is to be noted that the supporting ledge 34 is rigidly attached to the transverse supporting member 18 and that the panels or wings 86 and 88 form a continuation downwardly of the mold surface of the member 18.
Because of the decreasing length of the panel 30 from the junction downwardly, it is possible to adjust the panel at any reasonable angle without any portion of the plate 30 extending beyond the flange of the inner mold 12 and the angulated connection to the end members fills the angular aperture at the end of the panel 30 so that the entire construction may be readily applied at any desired angle and in substantially fluid-tight relation so that cementitious material will not be lost through any undesirable cracks.
It will thus be possible to use the mold forms 10 and 12 to provide a cast structure 110 integral with the curb lip 100 and the curb 102 and preferably with a chamfer 112 adjacent the top edges thereof so that there will be no crumbling of the cast form.
For purpose of exemplification, a particular embodiment of the invention has been shown and described according to the best present understanding thereof. However, it will be apparent to those skilled in the art that various changes and modifications in the construction and arrangement of the parts thereof may be readily resorted to without departing from the true spirit and scope of the invention.
What is claimed as new is as follows:
A curb mold comprising a plate having a back panel, a sloping top panel, and an attaching ledge, said back panel and said ledge being substantially normal with respect to each other, said back panel tapering downwardly so as to be of decreasing length from the junction of the top panel to the bottom of said back panel, said back panel having a plurality of vertically disposed slots therein, a pair of end members, said end members each having a sloping portion abutting said sloping top panel, said end members each having a portion abutting said ledge, an inturned flange on each of said end members, said flanges extending along said back panel, an inwardly projecting member on said sloping portions of the end members, said inturned flanges extending along said sloping top panel, means operable to secure said end members in angularly adjusted position with respect to said plate, and a channel-shaped wing secured in laterally extending relation on each of said end members.
