  1. Hoist line to roof from outside of building. Make line fast under the cornice and around the chimney with approved knots.

Couple six lengths of 2 1/2-inch hose together and stretch to front of building, then the officer and all the men, except three who are left in the yard to attend to the hose and hydrant, go to the roof, taking with them the following appliances; roof rope, hose roller, ax, Perfection pipe holder and two nozzles, one open and one controlling, 1 1/4 inches each. On reaching the roof place hose roller on the cornice and make it fast with rope which is attached to hose roller for that purpose. Lower down roof rope. The man left in the yard fastens the rope around the hose, two feet from the butt, two half hitches and a binding knot, then the line is hoisted to the roof. Be sure to have two lengths on the roof for working. Fasten the line below the cornice with a rolling hitch (four turns around the hose with a half hitch over all and a binding knot) and pull the roof rope back on the roof and make it fast around the chimney with chimney hitch (one turn of the rope around the chimney with two half hitches and binding knot on the rope), Put on 1 1/4-inch open nozzle, Perfection pipe holder and order the water started.

  1. Remove burst lengths of hose from line between fourth floor and the roof and between fourth floor and the yard and replace with good lengths.

To remove a burst length of hose from line between fourth floor and roof, the first thing to do is to order the water shut off. Disconnect the line on the street, the next coupling to the building, and put in a good length of hose. Remove the roof rope from the hose and from around the chimney, and hoist the line to the roof. Take out the burst length on the roof, recouple up again and let the hose come back over hose roller and make it fast again with roof rope, as it was before.

To remove burst length of hose from line between fourth floor and the yard, shut off the water in the usual way, remove the roof rope from around the chimney and lower the line down to the men in the yard, who will remove the burst length from the line and replace it with a good length. Then ho_____ the line up again and make it fast around the chimney as before.

  1. Stretch two 3-inch lines from high pressure hydrant and connect to stand pipe. Fire on sixth floor

Remove caps from high pressure hydrant and put on a high-pressure gauge. Connect up two 3-inch lines, stretch to building and connect to two-way 3-inch Siamese connection on standpipe As soon as the lines are connected to the hydrant the engineer will open the main valve of the hydrant by turning the wrench twenty-one turns to the right hand, then place the wrench on the independent valve and wait for orders. When the order is given to start the water, open the independent valves by turning the wrench sixteen full turns to the right hand. The company takes with them one length of 2 1/2-inch hose (rolled up) 1 1/4-inch controlling nozzle and hose spanner. Proceed by stairway to fifth floor, remove house line from standpipe outlet, connect up company line, stretch up stairway to sixth floor, put nozzle through window and order the water started.

Fig. 42.

Stretch 3-inch line from high-pressure hydrant, connect to standpipe floor valve inside of building. Outside connection out of order.

Remove cap from high-pressure hydrant and put on a high-pressure gauge; connect up 3-inch line and stretch inside of building; remove house line from standpipe outlet on stairway and put on an increaser from 2 1/2 to 3 inches. A double female 3-inch swivel connection goes on the he-butt of the line and connects to the 3-inch increaser on the standpipe outlet. Fasten with a rope, two half hitches and binding knot around standpipe and two half hitches and binding knot around swivel connection and he-butt of hose, and order water started.

  1. Stretch two 3-inch lines and one 2 1/2-inch and make connection to turret pipe on hose wagon. Start water and operate the pipe.

See Fig. 41. First remove the caps from gravity hydrant. Get a two-way high pressure gate valve, 4 1/2×3 inches. This fitting goes on the 4 1/2-inch outlet on the hydrant. Connect two 3-inch lines to it; o_____e 2 1/2-inch line goes on the regular 2 1/2-inch outlet on the hydrant. Stretch the three lines from the hydrant to the hose wagon (Fig. 42). An increaser from 1 1/2 to 3-inch goes on the he-butt of 2 1/2-inch line, which is the first line connected with the middle inlet on the three-way connection on the the hose wagon. The two 3-inch lines are connected up on the outside. Two men go on the deck of the hose wagon to operate the pipe when the water is started.

  1. Stretch one 3 1/2-inch line and one 2 1/2-inch from gravity hydrant, connect to rail pipes on hose wagon and operate same with proper size nozzle.

Remove the cap from the 4 1/2-inch _____et on the gravity hydrant and put on a reducing cap, 4 1/2×3 1/2 inches. Connect a 3 1/2-inch line to this fitting. The 2 1/2-inch line goes on the regular 2 1/2-inch outlet. Stretch the two lines from the hydrant and connect to rail pipes on the hose wagon with 1 1/4 and 1 3/4-inch open nozzle, and start the water.

Fig. 44.

Stretch 3 1/2-inch line from the fireboat, connect to high-pressure hydrant and operate high-pressure hydrant.

Remove cap from gravity hydrant and Connect up 3 1/2-inch line and stretch to high-pressure hydrant. A double female reducing swivel connection, 3 1/2x 3 inches, goes on the he-butt of the 3 1/2-inch line. Remove cap of high-pressure hydrant and put on a high-pressure gauge and connect up 3 1/2-inch line. In operating the high-pressure hydrant open the main valve first and independent last. In shutting down, shut down the independent valve first and the main valve last.

  1. Stretch 3 1/2-inch line from high-pressure hydrant and connect to water tower.

Stretch out 3 1/2-inch line. Remove cap from high-pressure hydrant and put on a high-pressure gauge. An increaser from 3 to 3 1/2 inches goes on the gauge,

Fig. 43.

and a reducer from 3 1/2 to 3 inches goes on the he-butt of the 3 1/2-inch line, then stretch out from the hydrant and connect up to water tower. Two men on deck of tower to operate the pipe.

  1. Siamese two 2 1/2-inch lines into one 3-inch line, put on a Perfection pipe holder with proper size nozzle.

Stretch out two lengths of 2 1/2-inch hose and one length of 3-inch for lead line and connect to Siamese connection (which is 2 1/2×3 inches, then put on a Perfection pipe holder and one 1 1/2-inch open nozzle.

Stretch out four 2 1/2-inch lines with one 3 1/2-inch lead line, use an Eureka pipe holder and a proper size nozzle.

Four lengths of 2 1/2-inch hose and one length of 3 1/2-inch hose are stretched out in the yard and connected to a four-way connection (which is 2 1/2X3 ½ inches), then put on Eureka pipe holder with 1 3/4-inch open nozzle. The nozzle is 18 inches outside the collar of the pipe holder when made up. Two men place their foot on the step of the pipe holder, take hold of the nozzle and operate same. Fig. 43.

  1. Stretch out one 3 1/2-inch line with three 2 1/2-inch leading lines which can be controlled independently, with proper size nozzles.

One length of 3 1/2-inch hose and three lengths of 2 1/2-inch hose are stretched out in the yard and connected up to a three-way gate valve (which is 3 1/2×2 1/2 inches). The lines are lead out straight with 1 1/4-inch controlling nozzle on each leading line. Fig. 44.
