Fig. 17

In Fig. 17 is shown a fitting with four outlets all of the same size. This type of fitting will be found very convenient in many installations, and, although the design might be vastly improved, still, as it is, the fitting is perfectly sanitary.

Besides the special cast-iron soil fittings the estimator should bear in mind the special lengths of lead traps and bends.

Long 1/2-S traps, similar to Fig. 18, may be purchased at the additional price of what the extra pipe would cost, and thus save the labor and solder required to make a joint to piece the trap out so it will reach to the wall. These traps are made in 1 1/4, 1 1/2 and 2-inch sizes, and are

15 inches long over all. Long, full-S traps, as shown in Fig. 19, may be had in 1 1/4, 1 1/2 and 2-inch sizes, measuring 24 inches over all. As sinks and lavatories are set 2 feet 6 inches above the level of the floor, a trap 24 inches long will easily reach from the fixtures outlet to the floor.

Of the different types of lead bends that are made, each has advantages when used in certain positions. There is no economy in ordering an ordinary short lead bend, such as is shown in Fig. 20, and then piecing it out with a short length of lead pipe. The better practice is to purchase either long bends Fig. 21 or extension bends Fig. 22; extension bends are made in the sizes indicated in Table XXI.

In addition to the special fittings pointed out, there are a number of patented special fittings made which can sometimes economically be worked into a stack, although they are not desirable fittings to carry in

stock, as the stacks must be designed for their use, they not lending themselves to the building up of an ordinary stack. The enterprising estimator and contractor will keep himself posted in the designs of such fittings, and be familiar with their dimensions so as to use them when conditions warrant.

Table XXI. Dimensions Of Extension Lead Bends

It might be well to state in this place that bends are now made with one end spun tight, ready for testing. At the prices charged at present for spinning these ends shut - that is, thirty cents each - it is doubtful if there would be any economy in their purchase; when, however, these are sold at the regular price of lead bends, plus the cost of the extra lead required for closing the head, there will be economy in the use of such bends.

Another matter, which may at some time prove profitable to know, is that where special fittings, which are not carried in stock, are required they can be had upon paying the additional cost of a pattern, with, perhaps, a little extra for the trouble. The possibility of having special fittings made should not be forgotten, as occasions might arise in large installations where economy would be effected by having special fittings cast.
