Specification of Letters Patent.
Patented June 30, 1908.
riginal application filed June 2, 1905, Serial No. 263,398. Divided and this application filed July '7, 1906. Serial To all whom it may concern:
Be it known that I, ROBERT KIESERLING, a subject of the King of Prussia, and a resident of Altona, (Elbe,) Germany, have in vented an Improvement in Cement Paving, of which the following is a full, clear, and exact description.
My invention relates to improvements in cement aving, this application being a division of t e application ed by me on the 2nd day of June, .1905, Serial N 0. 263398, for improvements in cement paving, and for which a patentwas granted to me Dec. 25, 1906, No. 839,600.
According to my present invention I embed in a layer of concrete or cement, which may be upon a second such layer, gutters of U or V section; and I fill these gutters with some elastic substance, such as tar, masticcement, or the like. From the walls of the gutter project lugs, which are surrounded by the concrete, whereby the gutters are firmly held in place in the material.
The purpose 'of my invention is to simplify and cheapen the construction shown in the patent above referred to. 7
My invention is illustrated in the accompanying drawings, in which Figure 1 is a plan, showing a portion of a street paved according to this invention. Fig. 2 1s a cross section of a portion of the construction shown in Fig. 1 drawn to a larger scale. Fig. 3 is a side elevation of a gutter section as shown in Fig. 2. e
The pavement consists of two superposed concrete layers a b. In the upper layer a there is embedded a metal gutter c, which may either rest with'its base upon the surface of the lower concrete layer 6, or may terminate at some distance above this layer 72, so as to leave a layer of concrete between it and the latter, as shown in Fig. 2. d are lugs, stamped out of the walls of the gutter c and bent over outwardly. These lugs are naturally firml embedded in the concrete a and thus aflor the gutter c a thorough hold. After the pavement has been laid and the concrete has set, the tter c is filled with an elastic material e, suc as tar, mastic-cement,
caoutchouc, so that water can not collect in crete.
it. If desired, the gutter may be filled in this manner rior to being embedded in the conthe drawings a gutter of U-section is shown, but as already remarked, a V or any other suitable section may be adopted.
The gutter as a rule will naturally not be in one continuous piece, but will consist of a number of se arate lengths; and these are preferably laid directly adjacent or in close proximity to the curb j} and the two outer gutters 9 thus formed are connected at intervals by cross gutters h.
The gutters k can consist of two lengths which meet together at the middle of the street in an obtuse angle, so that when heavy carts pass over the same the stress will be met by two walls of the gutters and also by a part of the aving.
Having thus descri ed my invention, what I claim as new and desire to secure by Letters Patent is 1. Cement paving for streets comprising in combination two layers of concrete, two nar row gutters provided in the upper layer near to the longitudinal edges, a number of gutters dis osed transverse to said first gutters, and a filling of plastic material in all of said gutters, the gutters being ofa substantially U-shaped cross-section and provided with means for anchoring the same, substantially as and for the purpose set forth.
2. Cement paving for streets comprising in combination two layers of concrete, two narrow gutters provided in the top layer near to the longitudinal edges, transverse gutters meeting together in an obtuse angle, and a filling of lastic material in all of said gutters, whic gutters consist of resilient metal bent to a substantially U-shaped cross-section and provided with anchoring lugs, substantially as and for the purpose set forth.
3. Cement paving for streets comprising in combination two layers of concrete, gutters of resilient metal bent to a substantially U- shaped cross-section provided in the upper layer and having a number of integral lugs 1n the side walls thereof, and a filling of plastic material provided in each of said gutters, substantially as and for the purpose set forth.
