Application led March 16, 1910. Serial No; 549,669.

The object of my invention is to provide` an eflicient, durable, and sanitary structure,

comprising either a gutter alone, or combiningboth curb and gutter, easily made and I laid, and which will permit ready removal and replacement in part or in whole to meet any contingency which may arise.

To this end my invention consists in the novel metallic structure which I shall now fully describe by reference to the accompanying drawings in which A Figure 1 is a plan of myzcurb and gutter. Fig. 2 is a section on .fr-m of Fig. 1, show- 4 ingthe concrete and paving. Fig. 3 is a section on y-y'of Fig. 1. Fig. 4 is a section showing the application of a cover plate to the gutter at points where needed. The structure is composed of sheet metal plates of proper thickness, and is made up 80 of sections of desired length. The gutter portion is formed of a plate bent to present in cross section a top flange 1, a vertical inner wall 2, a gutter floor 3, an outer vertical abutment wall 4, and a retaining flange 35 5. The curb is formed of theinner vertical wall 2 of the gutter plateg, a second plate bent to present in cross section a top flange 6, a vertical wall 7 and a base retaining flange 8; and a top-plate`9. The several lengths or sections of these plates are secured in alinement by having riveted to one end of each a flange strip 10 which projects beyond said end and overlaps the ends of the adjacent plates (as shown in dotted lines in Fig. 1) to which they are to be secured by suitable bolts. To the under side of the gutter floor 3 1 deem it best to secure a cleat strip 12 on one section to receive the overlapping flange stri 10 of the adjacent section, which construction afl'ords good support and stiffens the structure.

The top plate 9 of the curb has its upper surface scored orl roughened, as seen in Fig.'

1, to'prevent slipping, and to present a good gutterk appearance, and said plate is secured 'to the'v upper flanges 1 and'6 of the plates on which it rests, by A suitable bolts 13.' 14 is a stiening supporting strip secured to the base flange 8 of the inner curb plate 60 and tothe vertical -wall 2 of the gutter plate. This strip 14 also serves to support the structure on thewI-beams 15 of the sidewalk. Y 'j In setting the structure the outer side-" walk wall 16 is carried up to receive the 1- beams 15, and the concrete is filled in around them. Then the inner curb plate is set in place, and the gutter plate also, and concrete is rammed in under them and filled in between them; then the'top plate 9 is put on. The side-walk concrete 17 is filled in upon the base retaining vflange 8l of the innerk curb .plate 'and-carried up'tothef top of the curb. The lstreet paving 18 rests 75 on the outer retaining flange 5 of the gutter platev and-is laid up against the abutment wall of said plate. The street pavement is thus well supported at its line of junction with the gutter and by its weight holds the gutter plate in place, so that with this mutual support a .close bond of union is made 'along a line at which it is important to have a good joint. Likewise at the inner side of the structure, the base retaining flange 8 of 35 the inner curbpplate aords both a support for the concrete 17 of the sidewalk, and lis itself held down in place by said concrete. The sections of the structure can be 'made' lin thel shop, and when assembled at Vthe work, a fewbolts will quickly and eifec` tually secure them together. It isbestto leave a clearance between the sections, as seen in Fig. 1, to provide for expansion andz contraction. 95

By havingV the top plate 9 of the curb a separate piece, opportunity is afforded for filling in the concrete and said plates can be readily removed for any purpose, as, for example, to substitute others, or to permit the laying in the curb of pipes or conduits. In places wherethe gutter has to be covered, as or drive-ways into private property, or at the corners to provide crossings, a curved metallic plate, such as is shown by 19 in Fig. 105H 4, ma be laid across the tter with its convex s1de up, and secured t erein in any suitable manner, as, for example, by end lugs 20 fitting in sockets in the walls of the gutter plate. This cover plate will furnish the necessary support as well as provide for the water channel under it.

At the curves of corners, the several sections of the structure will, of coursef'be beveled or chamfered to it together properly.

`With a curb and gutter structure as here shown, the best sanitary conditions will prevail. `There will be no depressions or holes, such as. are made by standing horses, and in which filth accumulates and remains. The surface will be unbroken and continuous thus providing for good sweeping and flushing.

In cases where the curb is to` 'be omitted, the inner vertical wall 2 of the gutter plate will be fastened directly to the outer facing of the side-walk.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is v 1. In curb' and .gutter structures, a metallic plate fashioned to present in cross section a vertical inner wall having an offset top flange, a gutter floor, an,v outer abutment wall and an outer retaining flange for the adjacent edge of the pavement to rest u on;4

in combination with a second plate .ashioned to present in cross section a laterally extending base-retaining part, a vertical wall and atop flange; and a to restinor upon and removably secured to said top anges of the vertical walls of the respective plates,

. and constituting with the first and second mentioned lates a curb.

2. In cur and gutter structures, a metallic plate fashioned to present in cross section a vertical inner wall having an offset top flange, a gutter floor, an outer abutment wall and an outer retaining flangelfor the adjacent edge of the pavement to rest upon, in combination .with a second plate fashioned to present in cross section a base retaining flange, a vertical wall and a top iiange; a top resting upon and removably secured to the top flanges of the vertical walls of the respective plates, and a supporting structure extending between said vertical walls secured to the base-retaining fiange of the second plate. y

3. In curb and gutter structures, a metallic plate fashioned to present in cross section a vertical inner wall having an offset top flange, a gutter floor, an outer abutment Wall and an outer retaining flange for the adjacent edge of the pavement to rest upon, in combination with a second platel fashioned to present in cross section a base-retaining lange, a vertical wall and atop flange, a top resting upon and removably secured to said top flanges of said vertical Walls, a supporting structure extending between said vertical walls secured to the baseretaining flange of the second plate, and a metallic cover plate overlying and separated from the gutter floor and secured to the adjacent walls of the structure.

4. In curb and gutter structures, a metallic plate of integral construction throughout and comprising a vertical wall having at its lower end a transversely curved portion constituting a gutter floor which latter has at its outer end an abutment wall projecting downwardly and terminating in a transversely extending retaining flange, in oombination with an auxiliary plate having a wall extending vertically iand to the rear of the vertical wall of the first ment-ioned late,

the last mentioned plate having at the ower- `end of its vertical wall an integral offset retaining flange, a supporting strip upon which said last mentioned retaining ange rests secured. to the vertical wall of the first mentioned plate, and a removable top plate projecting between and secured to the upper ends of the vertical walls of the first and second mentioned plates. v

In testimony whereof I have signed my name vto this specification in the presence of two subscribing witnesses.
