WILLIAM F. INNES, OFSTOUGHTON, MASSACHUSETTS.

Boo-r coNNnc'rIoN.

Application filed September 30, 1921. Serial No. 504,515.

To all whom it may concern: 7. Be it known that;v I, WILLIAM FQIN ES, a citizen of the United States, residing at Stoughton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Roof iConnections, of which the following is a specification. j

This invention relates to roof connections, and more particularly to a roof connection or fitting adapted to form a water tight'and gas tight joint between a roof and a vent pipe, outlet stack, or similar device.

An object of the present invention is to i provide a fitting which may be used as a rigid caulked joint or as a fitting whereby settlement of the roof or movement of the pipe line due to-expansion and contraction may take place without effecting the water tight joint.

A further object is the provision of su1table locking means adjustable to any type of roof deck whereby the fitting is made integral with the roof deck and strains between the waterproofing and flashing are eliminated. v p

The connection forming the subject matter of the present invention may be employed with roofs made of wood, concrete, tile or other material. It is adaptableto flat or nearly flat roofs and is also adaptable to roofs arranged at a considerable angle when used as a caulked joint.

In the accompanying drawings, I have P shown one embodiment of the invention. In

this showing: A

V Figure 1 is a vertical central sectional view showing the fitting applied, Figure 2 is a similar View of a portion of a roof showing the fitting applied,

Figure 3 is a detail view'of a portion of the locking mechanism, 7

Figuret is a central vertical sectional view of a portion of a concrete roof showing the invention applied,

Figure 5 is a bottom plan view of one section of theconnection,

Figure 6 is a side elevation of the member shown in Figure 5, and,

Figure 7 is a detail view showing-the fitting applied to caulked joint. 7

Referring to Figures 1 and 2 of the drawings, the reference numeral 1 designates a wooden deck forming the roof. The deck is provided with an opening for the reception of the fitting and for the 3 and are adapted passage of a vent pipe, stack or other lead line. The main'portion of the fitting consists of a ring 2 having an upper annular flange 3, adapted to be seated in a recess formed in the deck.

The lower end of the ring is provided with 7,

an inturned flange t. A pipe 5 which may be a vent pipe, stack, or other pipe is arranged witliin the ring, and a graphite mineral gasket 6 may bearranged on this flange. A hollowlead gasket 7 is supported on the m neral gasket when desired. A gland ring 8 is arranged over the lead gasket and this rlng is provided with a flange 9, adapted to overlie the upper flange 3 of the ring 2. Copper flashing 10 may be arranged over the deck adjacent the fitting and extend between the two flanges. In Figure 1 of the drawings, the gland .ring is shown in the position when first applied before being compressed and a flange 9 is spaced from the flange 3. As shown, a plurality of bolts 11 are arranged in openings in the flange to pass through alined openings 1n the flange 9.-.Nuts 12 may be arranged on these bolts. A strainer 13 is shown arranged over the roof.) As shown, the lower flange 14 of the strainer may be provided with openings adapted to aline with the openings'in the flanges 2 and 9 whereby the strainer is retained inposition by the fasteningmeans of the gland ring. In Figure 2 of the drawingsflhe gland ring is shown compressed with the nut 12tightened on the bolt. r

Referring in detail to'Figures 5'and 6 of. the drawings, the flange 3 is provided with downwardly projecting members 17, slightly spaced from the ring and connected thereto by means of a roan wall 18. The members 17 are provided with curved cutaway edges 19. A pin 20 projects from the ring into this cut-away portion and this pin is adapted toreceive a locking member 21, j which isprovid'ed with an opening adjacent oneedge to permit it to be inserted into the space between the ring and the member 17 'when arranged in the horizontalposition shown in dotted lines in Figure 6. After the locking member has been inserted, it may belowered to the full line vertical position with the upper edge 22 arranged between the member 17 and the ring.

When the locking member is to be employed with a wooden deck, as shown in Figures 1 and 2 of the drawings, a block 23 is arranged on the lower end of the locking member and in engagement with the under side of the deck. As shown, the block is provided with a sleeve 24 adapted to receive the lower end of the locking member and a set screw 25 is provided, adapted to engage the locking member and retain the upper face 26 of the block in engagement with the under side of the roof deck.

In Figure at of the drawings, 1 have shown a deck 27 formed of concrete. \Vhen the connection is used with a concrete deck, the lower end 28 of the locking member is extended at an angle and embedded in the concrete.

lV hen the connection is used as a rigid or caulked joint, a ring 29 is used in place of the gland ring, this ring being secured to the ring 2 by means of bolt 11 and nut 1 as in the other forms. A filling 30 of oakum or similar material is arranged above the inturned flange 4- of the ring 2, and molten lead is poured between the pipe and the fitting, as at 31. is shown, the fitting may be provided with a circun'iferential recess 32 in which the lead is adapted to flow to make a more permanent joint.

It will be noted that the fitting may be adjusted by means of the locking member in numerous instances, the under surface of the roof deck is irregular and not in. a plane parallel to the upper surface of the roof. The individual locking members may be adjusted according to the distance between the under surface and the upper surface of the roof at the point where the locking member engages. A particular advantage of the present invention is that it may be employed where a pipe is arranged close to the under side of the roof. An elbow or T joint may be inserted in place of the pipe 5 and extend below the roof deck and slightly spaced therefrom. g

It will be apparent that by means of the construction disclosed, a deck fitting is pro vided which permits expansion and contraction of me pipe, vent, or stack, passing through it and at the same time forms a water-tight and gas-tight fitting. When the fitting is employed with a roof arranged at a considerable angle, it is best employed as a caulkedjoint and the space between the rings filled with lead, as shown in Figure 7 of the drawings. By substituting the ring 29 for the gland ring 8 and filling the space between the connection and the pipe with lead or similar material, the connection can be changed from. an expansion joint to a rigid joint when desired. The graphite mineral gasket and hollow lead gasket are particularly useful where there is danger of settlement of the roof or pipe line.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example thereof, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, 1 claim:

1. A roof connection comprising a ring having an upper flange adapted to engage the roof deck. a gland ring having a flange overlying said upper flange, fastening means passing through said flanges, locking rods secured to said ring and projecting downwardly, and means carried by said rod adapted to engage the roof deck.

2. A. roof connection comprising a ring having an upper flange adapted to engage the roof deck, a gland ring having a flange overlying said upper flange, fastening means passing through said flanges, locking rods secured to said ring and projecting downwardly, and blocks adjustably 1nounted on said rods, and adapted to engage the roof deck.

3. A. roof connection comprising a ring having an upper, outer flange adapted to rest upon the roof deck, said ring being provided with an inner lower flange, a gland ring arranged within said first ring, said gland ring being provided with a flange overlying said upper flange, fastening devices passing through said flanges, and a packing resting on said lower flange and contacting with the lower edge of the gland rin i. A roof connection comprising a ring having an upper, outer flange adapted to rest upon the roof deck. said ring being pro vided with an inner lower flange, a gland ring arranged within said first ring and provided with a flange, overlying said upper flange, fastening means passing through said flanges, said first ring being provided with a circumferential recess on its inner face for the reception of a metal packing, and a packing disposed on said lower flange and engaging the lower edge of the gland ring.

In testimony whereof I affix my signature in presence of two witnesses.
