ROOFING FOR BUILDINGS AND OTHER STRUCTURES.

SPECIFICATION forming part of Letters Patent No. 315,977, dated April 14, 1885.

Application filed September 16, 1884.

T @ZZ whom if may concern:

Be it known that I, SETE G. TUFTs, a resident of Maineville, in the county of Warren and State of Ohio, have invented certain new and useful Improvementsin Roofing for Buildings and other Structures, of which the following is a specification.

My invention relates to an improvement in roofing of buildings or other structures.

The object of my invention is, first, to avoid the use of rafters, and to use in lieu thereof joists running horizontally, or nearly so. there by saving a large amount of material hitherto necessarily employed in a saddle or pitched roof; second, to obviate the liability of roofs being blown or? by making the joists flat, and much lower than the ordinary pitched roofs required.

Another object of my invention is to save a large amount of material, as level joists are used in place of rafters pitched or inclined so as to ,obtain the water-shedding facilities, hence decreasing the superficial area of surface of the roof with a correspondingly less amount of material required in covering the roof.

Another object of my invention is to provide a protected eave-trough which will carry ott the water shed by the roof without being opened or exposed.

These objects are accomplished by using graded troughs secured to the top edge of level joists, all of which will be fully set forth in Ithe description ci' the accompanying drawings, forming a part of this specification, in which*- Figure l is a perspective View of my improvement; Fig. 2, a cross-section on line .r x, Fig. l; Fig. 3, a similar cross-section showing a modification ofthe graded troughs; Fig. fi, a cross-section on line :r Fig. l, with a Slatted floor resting upon the roof. l Fig. 5 is a crosssection on line g/ y, Fig. 1.

A represents the frame of a building or structure upon the top of which my improved roof rests.

B represents the finishing-boards of the cornice.

C represents graded troughs, which are attached to the top edge of joists I). Between each of these joists D the roofing material is made concave, so as to form between each a reg- (No model.)

l ular graded trough, the pitch for the fall ofthe water being formed by a gradual increase in the concave depth of the bent roofing material, which may be of sheet metal, tar-paper, or other similar composition usually employed for roofs. Figs. l and 2 represent the shallow portion of the trough, commencing at one side ofthe building. as atc, Fig. 2, and gradually increasing in depth to the opposite portion, b. Where the buildings are large I employ a double graded trough, as shown in Fig. 3, the troughs'being inclined from the center of the building outward.

I represents a door resting upon the top of thejoists D. It is shown in Fig. las slatted, so that the water may pass down through openings iu the floor into the troughs C. Any mode, however, of allowing the water to pass through the door I into the ,trough may be employed instead of a slatted tloor.

obtain au outdoor platform ci an area equal to that of the building, on which articles may be placed, which in case of porches would be a convenient place for sitting; or it may be employed on the roofs of houses for hanging clothes, or other platform conveniences.

I do not wish to limit myself exclusively' to the use of level joists D, as a slight inclination of the joists would not materially increase the expense or prevent the pitch or shedding capacityof the roof from being substantially obtained by gradually increasing the pitched or graded concave troughs secured to the upper edges of the joists forming the frame of the roof and occupying the space between the joists.

I believe I am the tlrst to construct a roof which employs joists the upper surfaces of which are level, or nearlyso, and still a sufticient shedding capacity is obtained by graded troughs secured to the top surface of the joists and lying between them, and only occupying the space between the joists. I have found by experience that the pitch of the troughs alone will furnish sufficient fall to carry off the water.

Another important advantage is derived from the use of my graded troughs O to form the roof or shedding-surface of the top of the building. Great difficulty has been occasioned by the use of eavespouts, because of By the use of this slatted oor I, or its equivalent, I

d represents an opening formed at the ends of trough C, between the ends of the trough and the facing-board D. Fig. 5 represents the cave-trough F inclined to carry off the Water through spout G.

Strainers or Wire-gauzev may be attached to the top of the joists for covering the troughs, which will allow the water to pass through'intothe tiough B, and yet prevent leaves or Jtrash from being carried into the troughs or spouts. y

It will be obvious that -my improved eavetroughs can be used with any form o' troughed roofs, Whether pitched rafters or level joists are employed.

I desire to claim the construction and arrangement of the eave-trough, broadly, Without regard to the form of joists or rafters employed.

' I claim- 1. A roof composed, substantially, of joists D, the upper edges of Which are substantially level, and the shedding surface -forrned of gradually-graded troughs C, attached to the upper edge of the ]oists, which troughs incline to one or more sides ofthe building in a gradually-increasing pitch sufcient to shed the Water, substantially as specified.

2. A roof composed, substantially, of the substantiallylevel joists D, facing-board B, and gradually-inclined troughs G, substantially as specied.

3. In combination withv substantially-level joist, D, double graded troughs C, pitching from the center outward, and forming a double .Water-shed for a roof, substantially as specifled.

4. In a roof, in combination with thejoists D, the graded troughs C, attached to the upper surface of said joists and lying betweenv them, and formed with a water-opening, d, at the end of the troughs and inside the facingboard B, substantially as specified.

5. In combination with a graded troughed In-testimony whereof I have hereunto set my hand. SETH G. TUIFTS. Witnesses:
