RAIN WATER PIPE Application filed September 21, 1928 Serial No. 307,495, and in British IndiaApril 30, 1928.

This invention relates to rainwater pipes andhas for its object to provide a rain water 1 pipe .Whichcan be secured in position more cheaply and in a better manner mechanically than rain water pipes-are n'ow fixed Another object is to provide a rain water pipe which needs no separate brackets, collars or fixing bands requiringnails on either side, and a still further object is to avoid the use of pairs of cast perforated lugs or ears on a rain water pipe through which spikes is a brittle projection and there is a great;

danger that in driving'a spike through the hole therein and into a wall the hammer may i hit and'break off the lug. Further owing to two lugs at least being needed, one on either 'side of the rain Water pipe, and owing to the difficulty of driving spikes in theexact' position desired in a'masonry wall it often" occursthat thespikes go out of position in driving or become crooked with the result that aside strainand'eccentric pull is thrown on the cast iron lugs which they are quite "unfitte'd to resist, being of thin cast iron.

' Sometimes rain waterpipes 'are fixed by t usingsecuringbandswhich are placed around the pipe and secured by driving a spike there-through on either side of the pipe.

Such bands hold the pipe in place but usual- 1y do not support the different length which accordingly nest'into-each other, with the result that the lowest pipe carries 'the weight of all the other pipes thereon, which weight may be transferred thereto unevenly owing to point contact.

1 In either of these caseseach length of. the

pipe nee'dsat least two spikes to hold it, and these spikes may or may not be efiicient in helping to carry the weightiof the pipe.

f r Y r of the pipe or spout length is a part which is V length.

I Now according tothe present invention a single spike or the like may be used for supporting each length of pipe. This method accordingly reduces the number of spikes or the like to half, thus reducing cost andlabour. a

The spike is moreover driven on the centre lines of the rain water pipe and hence tends to carry the pipe suspended therefrom in the most efficient manner. There can thus projections are not so likely to be damaged or broken off as the large ears or lugs on ordinary castiron pipes.

Further objects and features will be apparent from the following description.

The invention consists of an improved rainwater pipe ofthe spigot and socket type adapted to be suspended from or supported by a single simple nail, spike hold-fast or the like supporting means, characterized by this that the socket which is'intended, when 1 in use,to be at the upper end of the'pipe length is provided with an aperture or slot in the walls thereof for the introduction therein of or attachment therefrom to the supporting means, and these walls give sufficient clearance between them and the spigot end of the next length'of pipe which is to be introduced into the said socket end to allow of the pipe being thusjsupported and thereafter the next length of piping'thereabove bef from said socket end, characterized by this that the perforated, slotted or apertured part kinked out or off-set from the socket part by such amount that the head of the nail, spike or other supporting means intended to be driven into the wall to support the pipe shall not prevent the end of the next section of the pipe above from being fitted into the section already erected and fixed.

The pipe may be one in which the hole, slot or aperture is made adjacent to the top of the pipe and an intermediate attaching means, for example a flexible piece of wire, or a metal loop or hook,,or a chain, is en gaged in said hole, slot or aperture and is adapted to be hooked over or to engage the supporting nail, spike or the like supporting means to support the pipe or spout length. Alternativelythe hole, slot or aperture made in the socket of the pipe may be adapted to support therpipe directly from a supporting means with a flattened head.

The pipe according to this invention may have an apertured and slotted socket and in addition afoot or staying surface, for examplea block, projection or projections, with a flat portion thereon adapted to engage the wall towhich the pipe or spout is to be fixed for the purposeof steadying the pipe against the wall, enabling it to hang vertically from its nail or the like and to prevent, by frictional contact with the, wall, any tendency to-sidc movement.

T he; pipe is one which alternatively is adapted to be supported by having an aperture therein enabling it to be wired to a sup porting nail, or-the like.

The invention includes a pipe having in combination a socket part at its upper end to engage the spigot or lower end of the pipe or spout length above an aperture in the socket part in a portion thereof offset to give cleanancebetween the inner side of said offset portion and the spigot or pipe part which is toenter the socket, said clearance being sufficient to enable the head of the nail or supporting means, or attachment hereto, to

lie between the said part and the said spigot or end.

Theinvcntion will now be described with reference to the accompanying drawings, in which Figure 1 is a vertical cross section through a pipe.

Figure 2 is a horizontal cross section on line A-A of Figure 1, and

Figure 3 isa modification indicating a different manner of supporting the pipe or spout using a flexible member for holding the same to the-spike or the like.

In these drawings the pipe or spout 1 is provided-with a socket 2 into which the spigot end of the pipe orspout length above is intended to be an easy fit.

In this socket end a slot 3 or other suitable aperture 4 may be made so that the pipe or spout may be hung directly from a spike,

nail or hold-fast 5 driven into the wall on the center-line of the pipe. The socket part 2 will be made sufficiently large or have sufficient clearance to allow for the head of the said spike or the like to remain in the space between the inner side of the socket and the outer side of the spigot end.

The socket part of the pipe or spout need not necessarily be made circular in plan but might on the contrary be provided with a projection or bulge in that part of the socket in which the hole 4 or slot 3 is made. This bulge or projection might be flattened on its outer side at the part which rests against the wall so that the said'bulge or projection serves thetwo-fold purpose of allowing ample clearance for the spike head or the like and also at the same time serves to steady the pipe or spout length against the wall.

To steady'the pipe or spout against the:

wall and also to support it away from the wall at a distance which will cause the pipe or spout to hang vertically from its spike or nail the projections 6, 6, are provided which engage the wall surface 7. These projections steady the pipe owing to the frictional contact with the wall surface. It will be observed that the size and projection of these parts 6, 6, is considerably less than that of the part 8 (shown in dotted lines on Fig- 2) which parts indicate a known form of bracket which has sometimes-been cast onto a length of cast iron rain water piping so that the pipe may be secured to the wall by an extra spike 9. These known brackets 8 have usually been used in pairs in spite of the fact that it isvery difiicult to drive two spikes evenly'and at desiredpositions into a masonry wall. In using these known types of brackets 8 difliculty has been often experienced owing to the danger of the brackets being broken off whilst the spikes are being driven through them. Figure 3 shows an, alternative method of supporting the spout according to which the spout is supported by a flexible means such as a stiff iron wire which is passed around the pin 11, threaded through the hole 4 in the socket part and attached in any convenient way to the spike 501.. It will be noticed that in this manner of support the clearance needed between the spigot end and the socket is less than that needed when the spout is hung directly to a spike-or the like unless the head of the spike is made very flat indeed.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. An improved rain-water pipe of the spigot and socket type having an aperture in the socket end, headed supporting means engaged through said aperture for supporting said part, and said apertured part being offset from the main part an amount sufficient to allow the headed portion of the supporting means to be positioned further from the axis of the pipe than the inner surface of the main portionof the pipe whereby to per- I smooth while the upper end is enlarged to form a socket, the walls of the socket being provided with an aperture of a size to enable the pipe to be engaged over and hung upon the supporting means, said walls being also arranged to give suflioient clearance between them and the smooth end of the next length of pipe so that the latter can be introduced into the socket and supported and also posi tioned in spaced relation to the outer end of the supporting means.

3. A rain-water pipe according to claim 2, in which the aperture made in the socket of the same is adapted to support the pipe directly from a supporting means having a flattened head.

4;. A cast iron rain-water pipe accordin to claim 2 having in addition a staying sur ace in the form of a projection provided with a flat portion thereon adapted to engage the Wall to which the pipe is to be fixed for the purpose of steadying the pipe against the wall, enabling it to hang vertically from its supporting means to prevent, by frictional contact with the wall any tendency to side movement. 7

In testimony whereof I hereto aflix my signature this 10th day of August, 1928.
