IIENRYII. VAINVRIGHT, OF PHILADELPHIA, PENNSYLVANIA.
CONCRETE CURB AND GUTTER WORK.
SPECIFICATION forming part of Letters Patent No. 614,587, dated November 22, 1898.
v Application led January 26, 1898. Serial No. 668,016. (No model.)
ent case is merely a superficial contact on To all whom t may concern.-
Be itknown that LHENRY H. WAINW RIGHT, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in the Construction of Concrete Curb and Gutter Vork, of which the following is a specification.
This invention relates to improvements in the constructin of curbing, guttering, and similar concrete Work.
Vhen curbs, gutters, steps, copings, and similar work are constructed of concrete, it is indispensable that the corners of the curbs, glitters, steps, or copings shall be protected from breakages due to the collisions of vehicles and other objects therewith, and I have devised a system of protecting such corners by practically continuous bars of iron or steel. This system is not broadly herein claimed, since it is the 4subject of my earlier patent; but I do claim the improvements thereon hereinafter particularly described.
Said improvements, in general terms, comprise the following principles and mechanical elements: The protection of the corners of the work consists of a bar of galvanized iron or steel of peculiar shape, hereinafter termed a T-bar, the sections of which are laid with closely-abutting ends, so that the sections together form a continuous bar. Now I have discovered that when a surface of iron or steel is backed with concrete such an adhesion or union takes place that the iron or steel is held to the concrete with great tenacity even when the iron or steel is not embedded in but merely laid .firmly against the concrete backing. I
have made a highly useful application ofvthis discovery in my present invention, wherein I first set up brackets containing guideways. These brackets support the protecting-bars while the cement or concrete backing which forms the curb is being laid, shaped, and set. IVhen set, the union between the cement or concrete and the bars has taken place and said bars are held most firmly in position practically as a'partof the structure itself. It is to be particularly noticed here that the structure mentioned presents a very differentcondition from that existing when a bar of iron or steel, as a staybolt or tie-rod, is embedded in a mass of concrete. The presgutter.
only the back and tongue of the protectingbar, and embedding the whole bar in the concrete is impossible, since that would defeat the purpose of the structure, which is that the bar should project or show at the front of the work. I believe such a structure is new in the art and is of great practical utility, for it very greatly reduces the cost and increases the facility of constructing the protected work. To permit of any general use of such protecting-bars, it is also indispensable that the color of the bars should be closely similar to that of the general body of the work and that the bars should not discolor under influences of the weather, for otherwise the disagreeable appearance of the bars will prevent their general use. I obtain the desired result by galvanizing the bars, thereby approximating their color closely to that of the concrete and preserving the color of the bars unchanged for long periods of time.
Particularly when asphalt or concrete paving is used in a roadway it is desirable to protect the joint between the gutter and the paving, and I effect this by laying at this place iron or steel bars end to end, forming a continuous protection. These bars can be laid on the foundation prepared for the gutter, and when the pavement is finished the bars remain firmly in place, protecting the edges both of the gutter and the paving.
Referring to the drawings which accompany the specification to aid the description, Figure l, Sheet 1, is an isometrical perspective of the invention applied to a curb and The brackets which support the T- bars are shown bolted to stakes which are driven into the ground. Fig. 2, Sheet l, is a rear elevation of the T-bar and supports. Fig. 3, Sheet 1, is an isometrical perspective of a T-bar on a larger scale than that of Fig. 1. Fig. 4, Sheet l, is an isometrical perspective of one form of bar for protecting the front `edge of the gutter. Fig. 5, Sheet 2, is an isometrical perspective of a curb and gutter with a modified form of upright for supporting the brackets of the T-bars. Fig; 6, Sheet 2, is a broken sectional elevation `on a large scale, illustrating the manner of securing the bracket to the upright. The upright in this iigure and in Fig. 5 is shown provided with a base to IOO 2 eimer' support it. Fig. 7, Sheet 2, is a broken rear elevation of a T-bar, bracket, and support, and indicating a clip (shown in perspective in Fig. S) forsupporting the contiguous ends of two sections of the T-bar. Fig. 9, Sheet l, is a sectional elevation of a curb constructed with a horizontal leg or support for the brackets which guide the T-bars.
Referring to Figs. l to 4, A is the concrete, laid on suitable foundation material B in the usual manner. The iirst step is to set up uprights j in the excavation bydrivin g the pointed ends thereof into the earth, Figs. l and 2. Then brackets 7.1, slotted, as shown, to render them adjustable, are secured by bolts d to the uprightsj at the desired inclination and position. Said brackets 7o are recessed at their front ends, forming guideways to receive the tongues or ribs f of the T-bars E, which bars are preferably shaped as shown in Fig. 6. Said T-bars E are of iron or steel and galvanized to approximate their color to that of the concrete and to protect them from the weather and are of any suitable length. rlhe uprights j are set at distances apart-,about equal to the length of said T-bars. Said T-bars are set with their ends abutting, so as to form a practically continuous bar, and to support their contiguous ends I may employ Sheetmnetal clips F, Fig. S. These clips are set in the aforesaid recesses of the brackets 7V and the contiguous ends of the ribsf of two adjacent T-bars and laid in the clips, as seen in Fig. 7. I can plainly also secure a bracket on each side of the uprights j and then place the end of one T-bar on the one and the end of the adjacent T-bar in the other bracket.
When the uprights, brackets, and T-bars are in position, the concrete is laid backing up against the T-bars, as plainly seen in Figs. l, 5, and G, the T-bars forming the corner of the curb. When the concrete sets, a union is eifected between it and the surface of the T-bars, which fixes the latter firmly in place and practically as a part of the concrete struc ture.
The front edge of the gutter is protected by bars of iron or steel Gr, laid between the gutter and the street pavement, as shown. Then the concrete of the gutter sets, the union referred to fixes said bars lrnily in position.
In some cases it may be preferable to construct the uprights j', which carry said brackets 7c, with bases to support them, as shown in Figs. 5 and G; but the other details of the structure will be the same as those hereinbefore described. It may also be desirable in some cases to construct the bars G', which protect the front edge of the gutters, in L shape, as seen in Fig. 5. Their application and use are otherwise the same as hereinbefore described. I may also, whenever it is desirable, place the supports jz of the brackets 7.; horizontally, as seen in Fig. 9, and I prefer to twist said supports lf2, as shown. The other details of the Work are the same as hereinbefore described. The aforesaid brackets 7c receive the ribs f of bars E loosely for the purpose of holding said bars in place until the concrete sets. After that the union between the concrete and the bars holds the latter iirmly in position. The bars are not fastened to the brackets, and While said brackets of course remain in place after the work is iinished, because they cannot be removed without destroying the concrete, they do not fix the bars in place, this fixing being Vdue to the aforesaid union between the concrete and the surface of the bars. Finally, I may use brackets in one piece with their supports to guide the T-bars during construction of the work; but I prefer that the brackets shall be separate from the supports and adjustable thereon.
Now, having described myimprovem en ts, I claim as my invention- 1. The combination in curb and gutter work, of a continuous galvanized-metal T- bar at the exposed corner of the work, brackets adapted to support said bar during the progress of the work, and concrete backing laid against the said bar and embedding said brackets, substantially as and for the purpose described.
2. The combination in curb and gutter work, of a continuous metal T-bar at the exposed corner of the work, brackets recessed to receive the rib of said bar and support the bar during the progress of the work, and concrete laid against said bar and embedding said brackets, whereby the union between the set concrete and the bar holds said bar in place, substantially as described.
The combination in curb and gutter work, of adjustable recessed brackets, a continuous metal T bar provided with a rib adapted to fit said brackets, and concrete laid against said bar and embedding said brack ets substantially as described.
Signed at Philadelphia, in the county of Philadelphia and State of Pennsylvania, this 20th day of January, A. D. 1898.
