SPECIFICATION forming part of Letters Patent N o. 791,068, dated May 30, 1905.
Application filed August l0, 1904. Serial No. 220,282.
T0 (ir/ZZ whom, it may concern:
Beit known that I, LoUIs C. BAKER, a citizen of the United States, residing at 808 Sixteenth street, Parkersburg, in the county of Wood and State of West Virginia, have invented certain new and useful Improvements in Molded Roof Collars and Flashings and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
For roof-pipes, such as soil or Ventilating or steam pipes, I have designed an improved adjustable collar and flashing and a ring for calking said collar for forming water-tight connections with the roof and with the pipe passing therethrough; and my improvement resides in lead molded blank members each having an identical collar and flashing part, so that in assembling them with the pipe each collar part can be cut and shaped so as to change its original blank form from a horizontal roof to roofs of any angle or pitch and to form when assembled a collar of double walls around and in contact with the walls of the pipe, whereby each member is interlocked with the other in being fitted to the pipe. A lead calking-ring supplements the collar members and forms a clamp and a calk for securing and sealing the collar members at their joining with the pipe and at the meeting ends of the outer collar part.
In the accompanying drawings, Figure 1 shows in perspective the molded collar members as they are produced in separate blank parts each with a flashing for a horizontal The dotted lines show the cuts made to adaptthe collar to pitched roofs. Fig. 2 is a vertical section showing the molded collar members and their flashings when the collar parts are cut and assembled on the pipe in a vertical position on a pitched roof and before the collar is calked by the ring to seal the pipe-joint. Fig. 3 is a side view of the separate molded members and their flashings, showing thc manner of cutting the collars to adapt them to assume a vertical position for a pitched roof. Fig. 4 shows the same in perspective. Fig. 5 shows in perspective the se arate collar parts and their flashings when fitted and locked one with the other when assembled on the pipe on a pitched roof. Fig. 6 shows in vertical section the collar parts and their fastening and calking-ring assembled on the pipe and the collar-joints calked by the ring. Figs. 7 and 8 show the calking and inclosing ring for the collars.
Looking at Fig. l is seen two identical collar-forming parts l, each having an integral flashing 2, the collar parts being formed like the letter U and rising from the flashing constitute each a molded member of the collar and its flashing, the top edges of the collar parts being parallel with the flashing. The blank members thus molded are adapted for horizontal roofs, but they can be changed for pitched roofs by removing awedge-sh aped part 3 (shown by dotted lines) from each side of one of the collar parts. This is done by a cut 4, extending from the edge of the flashing along the joining of this collar part with the flashing, and a out 5, exten ing from the edge of the collar obliquely to the termination of the base-eut 4, as seen in said figure, such cuts termination being at about the joining of the straight collar part with the curve'd part. This allows the undercut ends to be forced down to close the cut-out and to be bent around to complete the circle of the collar, as at 5 in Fig. 4, thereby making the collar vertical and the edge of the collar horizontal to the oblique flashing to suit the pitch of the roof. The edge of the collar of the companion member is cut down obliquely at 6, Fig. 4, around. its curved portion to conform to the horizontal edge 5 of the other member, so that when assembled the collar part of one member will be coiled within the coiled part of the other member, thereby forming double walls to the collar and locking the two members together, with the edge of each collar part meeting even and in horizontal relation to the oblique flashing.
Referring to Fig. 4, it will be understood that the ends'of the collars of both members are undercut at 4, as described, so that the free ends of each collar part can be bent in ring form, as shown in Figs. 4 and 5. In this interlocking relation of the collar parts the flashing of one member will lap with thc flashing of the other member, so that the cut of the flashing of one member will be within the collar and covered by the flashing of the other member when the two are closed and sealed around the pipe, the lead being beaten to effectually close the cut 6 at both sides of the overlap. In this way the collar and the flashing parts each being molded as a single piece the collars can be undercut, as indicated by full and by dotted lines, to allow them to be bent on their connection with the flashing from the straight form shown in Fig. 1 to the circular form shown in Fig. 5 to fit them around the walls of the pipe and to be adjusted to fit different sizes of pipes. In assemj bling the collars one of them is first secured to the roof by its ashing and the undercut ends of the collars are closely bent around the pipe The other collar member is then slid over t e collar and flashing of the fixed collar member and bent around it and secured to the roof. While a water-tight joint is thus made by the flashing with the roof, the joint between the collars and the pipe is eX osed for leakage, because the packing of the ead collar against the walls of the pipe will not make a watertight oint, as in Fig. 2. To seal this joint, I provide a calking-ring 8, of lead, which when fitted over the ends of the collar parts stands above their edges, as at 9 in Fig. 2, and while the ring is driven tight upon the collar parts with a clamping function upon the pipe the projecting edge 9 of the ring is caused to form a calking element when beat over, as at 10, upon the edges of the collar members and within thejoint between the latter and the walls of the pipe, as in Fig. 6, thus sealing the collar-pipe joint. Referring to Fig. 1, it will be understood that while the parts molded in blank, including the flashing of each collar part, are in the form adapted for horizontal roofs, each collar part at its open end is undercut at each side to separate its ends from the flashing to allow them to be bent around y the pipe, as indicated by dotted lines in Fig. 1, while maintaining the horizontal relation of the edges of the collar with the roof.
In Fig. 3 at 1 1 is seen the cut and in dotted lines 12 is shown how the collar is beat down on the ashing and closing the'cut to bring its top edge horizontal and its collar wall 13 vertical to fit the Vertical pipe. This advantage is due to molding the collar and the flashing parts in one piece, and it saves time, solder, and skilled labor in the work of applying the collar and its flashing. Different calkingrings are molded for dierent sizes of collars and can be applied to any kind and form of roof.
I prefer to mold the ring with a depending skirt 14 of thin walls, so that its lower edge can be trimmed off to suit the pitch of the roof and to form a tight joint with the flashing by beating thereon the edge of the skirt and serves to inclose and seal the joint at the meeting ends of the outside collar part, which would stand open more or less, as in Fig. 5. The collars may be of any suitable projection or height from the flashing and the skirt part can be adapted for horizontal roofs and forms itself the calk for the top joint of the collars, a vertical closure for the collars, and a seal around the collars at the flashing.
