BURT J. SINK, AOF BUFFALO, NEW YORK, ASSIGNOR TO THE BARBER ASPHALT PAVING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF WEST VIRGINIA.
APPARATUS FOR REPAIRIN'G ASPHALT PAVEMENTS.
SPECIFICATION forming part of Letters Patent No. 734,141, dated J' uly 21, 1903.
Original application filed July 29, 1896, Serial No. 600,92. Divided and this application iiled April 30, 1900. Serial No. 14,885. (No model.)
To @ZZ whom it may concern:
Be it known that I, BURT J. SINK, a citizen` of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain newr and useful Improvements in Apparatus for Repairing Asphalt Pavements, of which the following is a specification.
In repairing asphaltum pavements it has become the practice to make useof a heater whereby a body of dame or other highly-heated body is brought upon or adjacent to the surface of the asphaltum top coating, so as to soften the latter and permit the removal of a portion thereof before the application of additional asphaltum mixture. In practicing this mode of repairs injury has often resulted from the fact that portions of the pavement become heated beyond the point where the pavement is to be repaired by the addition of new material, and as a result the said outlying portions become disintegrated from the action of the heat. In other words, those portions of the pavement which have not been heated and not covered by the repairs are burned, so that they are no longer in perfect condition. Y
The object of my invention, which is a division of my application, Serial No. 600,920, filed July 29,1896, is to make use of the ordinary heating appliances, with all of the facilities which they afford, andfat the same time to avoid unduly heating any portion of the pavement except thatA area which is to be covered or removed in the process of repairs. To this end I make use of the means hereinafter set forth, and illustrated in the accompanying drawings, in which- Figure l is an elevation illustrating a Lasterheater combined with my improved means for preventing the heating of the pavement beyond the repair-section. Fig. 2 is a view illustrating one arrangement ofv the protecting-guards. Fig. 3 is an enlarged view of part of one of the guards, illustrating they construction thereof.
Different apparatuses are commonly employed for heating the surface of the top layers of asphaltum pavements-for instance, crates with incandescent coals supported just above the pavement by rollers or casings with blast-tubes, or, as illustrated in Fig. l. with a hood A, supported uponwheels B B, the said hood beingA supplied with vapor, which is ignited, forming a flame which fills the en- 4.tire hood and heats the pavement beneath,
the area ofthe crate or hood constituting the uniform area of the heater.
In connect-ion with the heater, whatever its form, I make use of guards C in the form of sheets of refractory material, which may be laid upon the pavement so as to leave a space p x between them ofgthe size and outline demanded by the repairs and yetcover the outlying portions of the pavement. By this means when the heater is brought above the guards so arranged the heat will act with reducing eiect only upon the part of the pavement exposed Withinv the area a: between the guards, which latter willvprevent the undue heating of any of the surrounding portions of the pavement. I have found by this means I am enabled to reduce the exposed portion of the pavement (ofanydesired shapeand dimensions less lhan those of the heater) to almost a melted state vwithout in any way overheatin'g any of the surrounding portions, and
therefore when the heated portion is removed or the new material is applied thereto the surrounding portion will maintain it-s integrity as well as if no Vrepairs had ever been made.
The guards C may be made of any suitable refractory materia-l; but I prefer to make them of asbestos board or paper of about one inc h in'thickness, and as said paper has very. little `tenacity or tensile strength the surface fis very apt to be worn away and the guards .are very apt to be broken, and I therefore embed in each surface of each guardia suitable binding material. Preferably this'is Vin the form ofV open wire-netting E, such as is used for fencing purposes, which is embedded in the paper in the course of its'manufacture at the surface thereof.
Without limiting myself to guards of any In testimony whereof I have signed my special form or construction or material, I naine to this specification in the presence of 1o claim as my inventiontwo subscribing witnesses.
The combination in an apparatus for re- 5 pairingasphaltum pavements, ofa heater and l BURT J' SINK a series of guards of refractory material ad- Witnesses: justable below and in respect to the heater, A. E. T. HANSMANN,
substantially as set forth. J. J. MCCARTHY.
