8 Claims.
This invention relates to roof drains, and particularly. to the means for attaching the same to a Waste pipe or other drainage member.
In the ordinary construction, roof drains are generally attached to the roof structure by suitable fastening means, or the drain body may be permanently embedded in a layer of concrete, as the building specifications may require. Under the present conditions of construction, difliculty 10 is experienced in making a'joint between the outlet of the drain bodyand the waste pipe. The Waste pipe frequently is not in alignment with the opening in the drain body and the ordinary n methods of coupling are not satisfactory.
` A further difficulty is experienced if any contraction or expansion should occur in the waste pipe line, or if there is any appreciable movement of the piping during the assemblage of the same. In both cases the utilization of the ordinary couf pling means would tend to unseat the drain body when the expansion or distortion occurred, and as a consequence rupturing of connections would result.
Having in mind the difficulties experienced in f roof drain constructions, it is therefore an object of my present invention to provide a roof drain construction having means for attaching the roof drain to-a waste pipe which allows for the necessary expansion or contraction or misalignment of the latter.
It is a further object of my invention to provide a roof drain having means for sealing and securing the waste pipe to the drain body, incorporated in the drain structure in such manner as to be accessible through the top of the drain body from the roof of the building.
Further and more specific objects of my invention will appear from the following description given in connection with the accompanying drawings, where Fig. 1 is a vertical cross-section through'the center of a roof drain, illustrating my invention; Fig. 2 is a fragmentary horizontal cross-section taken along the line 2-2 in Fig. 1; Fig. 3 is a vertical cross-section of a roof drain,
illustrating another form of my invention and Fig. 4 is a fragmentary horizontal cross-section .taken along the line 4 4 in Fig. 3.
Referring now to Fig. 1, I have shown a drain body l, embedded in a layer of concrete supported f5.0 bythe ordinary roof structure. Roong material 2 is secured to the drain body by means of an annular clamping ring `3. Clamping posts 4 are carried by lugs 5 arranged at intervals around the circumference of the drain body and afford fas- 5 tening.I means for the annular clamping ring 3.
. will be required than in another.
A removable vertical domeeshaped strainer l5, and annular sediment cup l, are seated within the recess 8 of the drain body upon a series of lugs 9. A cylindrical housing l@ is cast integrally with the drain body i and forms an outlet for the 5 recess il. The housing lll is flanged inwardly as shown at Il, and forms a packing boX adjacent the bottom opening l2, which will be hereinafter more fully described.
When the drain body is set in concrete, as `1`0 illustrated in Fig. 1, it becomes necessary to attach the waste pipe 29 either from the under portion of the roof or from the internal body of the drain at the surface of the roof. Experience has shown that a rigid joint between the drain vl5 body and the waste pipe is impractical. When installing the plumbing in a building, the waste pipes 20 will vary in their lengths considerably, and thus, in one instance, a longer coupling between the waste pipe and the outlet to the drain 20 Misalignment of the pipe line or any undue expansion or contraction will necessarily prohibit the use of a rigid connection between the bottom portion of the drain and the waste pipe. 25
To obviate these diculties and to facilitate the connection of waste pipes to drain bodies under various conditions of construction, I have provided an expansible and contractible connector which is capable of being inserted from the 30 under portion of the roof and which may be sealed and connected to the drain body from the internal recess therein on the upper surface of the roof. f
The Waste pipe 2i! may be cut off to any conven- 35 ient length below the outlet of the drain body.
A thin Walled cylindrical sleeve 2l is then secured to the waste pipe @il by means of a threaded connector 22. The length of this tubing will be dependent upon the variable distance between 40 the top of the waste pipe and the lower opening in the drain body to be connected.
Having cut the sleeve 2l to the proper length, it may either be inserted in the opening l2 and then secured by the connector 22, or the sleeve 45 may be first attached to the waste pipe fil and the entire arrangement inserted into the opening I2. The drain body opening l2 may be considerably larger than the outer diameter of the sleeve 2| to allow for any misalignment of the 50 drain and plumbing assembly. It may thus be seen that no accurate alignment of the waste pipe 20 is necessary, so long as a suflicient length of the sleeve 2l is inserted in the opening l2. It is further apparent that the distance between the waste pipe 2|] and the opening i2 does not require the accurate positioning which would be necessary if a coupling or other screw-type joint were to be employed.
Having extended a sufncient portion of the sleeve 2i in the bottom of the drain body, the operation of tightening the same may be done entirely from the surface of the roof. In building constructions this element is important, as the workers below may slip the sleeves 2l into the drain while an assistant on the roof may, at the same time, or any period later, apply the clamping means. Where the time element is important, this construction facilitates present building methods.
With the strainer 6 and sediment cup 'l removed, the workman may then proceed to apply the seal between the sleeve 2l and the housing I0. An asbestos packing gland 23 or other suitable material is wound around the sleeve 2i within the recess formed by the flange il. An annular gland ring 24 is then inserted between the opening formed by the sleeve 2i and the housing lil. It may thus be seen that by a downward 25 pressure of the gland ring 24, the .gland material 23 will be compressed against the outer wall of the sleeve 2l so that a seal is formed between the waste pipe 2li and the lower housing of the drain body Il).
A series of slots i are disposed at spaced intervals around the circumference of the opening 28 in the bottom of the recess 8. Each slot has an opening 3i in its upper wall and at its one end thereof, so that a lug may be inserted there- An annular pressure ring 2E, carrying threaded bolts 25, is then inserted within the opening 23 at the bottom of the drain body. On the outer periphery of the ring 25 are disposed a series of lugs corresponding in number and position to the openings 3l in the slots 3&3. The ring 25, being thus inserted in the opening 2? and turned in a clockwise direction, will be locked against any upward movement by reason of the upper shoulder of the slot Sil. In this position the bolts 2G will rest upon the upper surface of the gland ring 24. The tightening of the bolts 2B will then apply pressure to the gland ring 24 and compress the gland 23 so that a seal is formed between the outer surface of the sleeve 2l and the inner surface of the flange I l.
The construction heretofore described has merit in present building methods in that it allows for the insertion of the waste pipe from the underside of the roof, while all of the connections and replacements may be made from the surface of the roof. The necessity of accurate alignment between the waste pipe 2li and the bottom opening of the drain l2 is thereby obviated, while in addition any expansion or contraction within the pipe line will be compensated when that condition prevails. Inspection of the drains and expansion joint parts may be made as conveniently after the completion of the building as before.
In Fig. 3 I have shown another form of my invention embodying the construction illustrated in Fig. 1. It has been found that the packing material around the waste pipe connection may become worn and that seepage may result between the drain body and the sleeve 2|. To eliminate this, I have provided an arrangement whereby the seal is made internally of the sleeve 2|, rather than externally, as illustrated in Fig. 1 of my drawings.
Referring now to Fig. 3, I have shown a drain body construction similar to that illustrated in Fig. 1. The cylindrical housing il), disposed at the bottom of the drain body, now acts as a skirt for the sleeve 2l. As in the construction shown in Fig. l, the drain body opening is made preferably larger than the outer diameter of the sleeve 2| for the purpose hereinbefore stated. A stationary annular gland ring 4i] is cast integrally with the drain body and forms an annular recess between the cylindrical housing lll and the gland ring 4S. A stationary pressure ring 4l, provided with threaded bolts 152, is disposed at the bottom opening 28 of the recess 8 in the drain body. The movable gland ring 43 is supported by its threaded engagement with the bolts 42, so that the tightening of the same will impart to the gland an upward pressure.
The assembly of parts is made in the same manner as that described in Fig. 1. The movable gland ring 43 is loosely carried by the bolts 42. The sleeve 2l connected to the waste pipe 20, may then be inserted between the cylindrical housing lll and the stationary gland ring 4l), the later sleeve having just been cut to the proper length, so that the necessary expansion may be accommodated.
With the dome-shaped strainer E and the sediment cup 'i removed, the operation of applying the seal can be accomplished from the roof of the building. By loosening the bolts 42 the movable gland ring 4S will drop into the sleeve 2l, until the connector 22 is reached. nector 22 should be of suflicient length to allow ample space for the insertion of the gland material 23. This is accomplished by merely winding the same around the removable gland ring 43, and between the inner surface of the sleeve 2l.
Upon the completion of this operation the hand may then be inserted within the ring 43 to position the same and reengage the bolts' 42. The tightening of the bolts will thereby compress the packing material 23 between the stationary and movable glands and against the inner wall of the sleeve 2l. In the event that any water should become lodged between the movable .gland ring 43 and the stationary ring 4U, I have provided small seepage holes 45 so that the recess between the rings may be properly drained.
It may therefore be seen that I have invented a new and useful joint for connecting waste pipes to roof drains, so that the waste pipe may be inserted from the interior of the building, and that all connections and repairs may be made from the roof of the building. I have further provided a joint which will compensate for any expansion, contraction or misalignment of the draining members, and one that may be inspected when in operation, from the roof level.
