Submarine Appliances And Their Uses
Deep Sea Diving, &c., &c.

In case the diver urinates in the dress, it should be turned inside out and washed with clean fresh water, and then allowed to dry. Care of Air Pipes.—The indiarubber pipes should also be cleaned and thoroughly dried before being packed away. Repairing Diving Dresses.—Prepared twill and indiarubber solution are pro- vided for repairing leaky dresses. If the leak is due to a tear, first wash the place in fresh water and thoroughly dry it. Cut two patches of twill of the size and shape required—one for the outside, and another for the inside of the dress. Three coats of solution are applied round the tear, each being allowed to dry before the next is put on. Applying one coat of solution to the indiarubber side of the prepared patch, put the latter in place. The patch may be smoothed down with a flat iron, or a smooth piece of wood; a flat weight should be placed on the patch to keep it down while drying. As soon as one side is dry the other can be repaired in exactly the same way. Superfluous solution can be removed with a piece of indiarubber, but it is better to lay it on the proper width, so as to avoid the necessity of cleaning off. If the leak is due to an imperfect seam in the dress, a quick repair can often be effected by rubbing solution into the channel of the seam ; if this does not answer, a long strip of twill must be applied in the form of a patch to the outside of the seam. Always wash all salt away from the neighbourhood of the leak before ATTEMPTING A REPAIR. SEE THAT GREASE, TAR, ETC., ARE CAREFULLY EXCLUDED. The IN- DIARUBBER solution should be kept covered air-tightly when out of use. If the solution is too thick, dissolve with pure naphtha. Inserting New Collars and Cuffs in Diving Dresses.—Having removed the old rubber collar and inner collar—which should be done after the careful application of naphtha, to avoid damaging the dress—solution out neck of dress, inside, about 2^in. in width all round, allow two hours for drying, solution out again, and allow to dry two or three hours, according to temperature of atmosphere. Solution out rubber collar inside and put on the canvas strip (if same is not already on the collar), then solution the outside of collar i|in. wide from outer edge; allow two hours for drying. Solution the inner collar about 2^in. wide on the inside, allow usual drying, then insert solid collar in dress and roll down. Insert the inner collar now, and roll down. Inserting Cuffs in Sleeves.—Solution out the cuffs 2|in. wide twice, allowing usual drying; solution out sleeves of dress twice, place cuff on cuff block, and insert in position and roll down. 35
