On the accompanying drawings, Figure 1 represents an exaggerated section through a strip of roofing material embodying the in,-

wit a waterproofing compound-such as asvention. form instrunientalities by which the roofing maqy be produced.

, he roofin comprises a body a, which is preferably a sheet or strip of wool felt or an- This body is saturated phaltum, pitch, residuum oils, or the like and its faces are comparatively rough and dry. Both faces of the body are coated with a layer 1) of heavier as haltum or pitch, which is preferably. applied 0t, and against one of the heated and sticky layers is pressed a sheet 0 of textile materia of comparatively close weave, such as duck, canvas, or other cloth. The textile covering completely covers and conceals the layer 6 and firmly adheres there to, so that the whole forms, as it were, a homogeneous mass bound together by the waterproofing compound. The canvas covering or outer layer is then covered with a coat of paint, as at d. The coat of paint need not be applied until the roofing has been put in place on the roof or against the walls or floor of a building, or it may be applied immediately after the canvas layer has been in- OOILOIfliZ-Bd in the finished material.

conventionally illustrating a process of 1 manufacturing the roofin thus described I have shownin Fig.2 the Ody a of wool felt as being drawn from a roll othrough a. tank or receptacle 7 which contains a waterproof ing compoun This compound may be heated in an suitablewa and it saturates the body. erleavingt jank? the saturated bod may be dried lay an apparatus illustrate conventionally at 8, after which the coatings or layers '6 are applied to the faces, thereof by passing it through a heated Fig. 2 represents in conventional tank or rece tacle 9. The canvas or other cloth a, whic is on a roll, as at 10, is drawn, together with the body a, between pressing devices 11 11, which press the canvas. firmly against the layer 5 tocauseit to adhere thereto. The aint may be ap lied by a roller e in a tanl f. The roofing t us formed may be dried, if desired, and is wound upon a roll 12.

A waterproofing roofing substantially as herein described possesses numerous advantages over those as hitherto manufactured. It may be rolled for shipment and unrolled with facility and without any of the convolutions adhering. The outer layer of canvas or cloth gives add ed strength to the material and causes the felt body to lie fiatfwithout buckling. The canvas may be coated with aint of any color, so as to harmonize" the canvas. ere the layer of asphaltum or pitch is exposed, as in ordinary prepared roofings, it is most unsatisfacto to pamt it, as the heat of the sun will (llr the black pitch or asghaltum throuph the paint, discoloring it. y m metho this is entirel obviated. Thea dition of the canvas ayer with its coatin of paint greatly increases the life of the rec g material, since the paint and the canvas mustboth be worn away before the asphaltum or layer of waterproofing corlripound is exposed.

aving thus explained the nature of the invention and described a way of constructing and using the same althou h without attempting to set forth all of the rms in which it may be made or all of the modes of its use, I declare that what I claim is-' 1. A roofing material com risin a body of suitable substance saturate wit a waterproofin compound, an exposed layer of wat roo g compound of sticky consistency an an outer coating of textile fabric united to the body by a layer of waterproofing compound.
