THE HAYES EXTENSION LADDER TRUCK.

THE HAYES EXTENSION LADDER TRUCK.

READY FOR SERVICE.

We present herewith several cuts showing the Hayes Extension Ladder Truck in various positions. This Truck has achieved a wide celebrity in the past few years for being most serviceable, practical and easily handled apparatus of its kind every introduced in the Fire Service. It is in use in quite a number of cities, and wherever used has given universal satisfaction.

The ladder is telescopic, giving a total length of from sixty to eightyfive feet from the ground, made in two slides, and worked by an endless chain and winch attached to the lower portion. The lower portion is hung on trunnions supported on an A frame, which stands on a turn-table which is attached to the main frame of the Truck. From the under side of the ladder is hung a pair of arms which carry a nut which is hung on trunnions, and through which passes a screw, one end of which is held in a swivel which is fastened to the revolving portion of the turn-table on the front end. The back end extends under the ladder, and the front end is squared for a crank, so that by turning the screw the ladder is raised to the required elevation ; then the turn-table is swung around, and, if necessary the extension of the ladder is run out, and the ladder is lowered over against the building, as may be desired.

As the ladders are being raised to a vertical position, they can, by means of the turn-table, be turned in any direction required, and by simply manipulating the turn-table, screw and extension cranks, the top of the ladder can be readily directed to any desired point within reach. The Truck can also be moved from point to point without letting down the ladders, thus enabling the Firemen to reach every point of a burning building. With a little practice this can be done with precision and great rapidity. In less than one minute the ladders can be fully extended and placed against a building, ready for service. In raising the ladders electrical wires can often be avoided, but if encountered a man can ascend the ladder at any angle and cut them. The ladders being raised by means of a powerful screw, the action is certain, and perfectly safe. Only eight or ten feet width of roadway is required for the Truck, and it can be operated as well in a narrow alleyas in a wide street. But five or six men are required to work it.

RAISING THE LADDER.

A rope is provided for handling the hose. To one end is attached a hook. The rope is passed over the ladders through a sheave attached to the top end of the extension ladder, thence it passes down under the ladders and through a snatch block provided on the frame. The end of this rope is left slack when the ladders are being raised. When they are in position the hose is hooked on and readily raised to the top, where it can be securely strapped to the ladders. The rope can also be made useful in saving lives and property.

AS AN ÆRIAL LADDER.LADDER EXTENDED.

As an Airial Ladder this Truck can be used with perfect safety to the height of the main ladder, which is about fifty feet in the First-class, and forty feet in the Second-class, from the ground. The ladder is placed in a nearly vertical position, and two lines of hose carried to the top may be directed by the Pipemen in any direction, carrying a full fire-pressure stream. The Truck is much used in this way, and gives the Firemen a decided advantage over fires in the upper floors of high buildings.

The Truck has been in service over ten years in San Francisco, Cal., and is now in service in many other cities, but never yet has any accident occurred caused by its failure to withstand any strain put upon it. The Truck c; rries the usual number of hand ladders, three of which are carried on rollers and can be removed without disturbing the others. The balance are “ nested ” together in the ordinary way ; it also carries the full complement of tools and equipments usually carried on a first-class Truck. The frame is made extra strong and supported by truss rods, is mounted on platform spring over front axle, and two full elliptic springs over hind axle. The hind gear is controlled by a cog gear operated with a wheel in the hands of a Tillerman, by means of which the Truck can be guided around short corners and through narrow alleys.

The timber of which the ladders and frames are built is procured at great expense from Puget Sound, and is known on the Pacific coast as “ Oregon pine.” This timber is peculiarly well adapted for this purpose ; it is comparatively light, very strong, and elastic as whalebone ; contains no pitch, is perfectly straight grained and free from knots. Such as is used for ladders is sawed “slash grained,” so as to give the greatest possible strength. The extension ladder is built strong enough to support two lines of hose and eight or ten men, and is supplied with appliances for quickly elevating ‘the hose. All forgings are made of best quality Norway and Ulster iron, and none but Nomoay bolts are used. The Truck is mounted on substantial “Archibald ” or “ Sarven ” Fire Department wheels. None but the best material is used in the construction ; much of the metal work is finished and heavily nickel-plated, and the balance and wood work is handsomely painted and ornamented with gold striping and scroll-work. We employ none but the best skilled workmen.

The Truck is built in two sizes, designated as first and second-class. The following comprises the regular equipment of the different classes :

First-Class—Weight, Complete, About 6800 Pounds—One Hayes Patent Extension Ladder, 80 feet long. One each of the following length hand ladders, made of “Oregon pine”: 30, 28, 25, 22, t8, 16 and 12 (roof ladder) feet. The 30, 28 and 25 feet ladders are carried on rollers. The 30 and 22 feet ladders are arranged to splice, making a ladder 48 feet long. Two short-handled hooks ; two long-handled hooks ; one chain hook ; two crotch poles ; two steel crow-bars ; four fire axes, with pike heads; four pitchforks; four leather fire buckets; 175 feet of manilla rope, with tackle and snatch block for hoisting hose ; one oil can ; seven brass hand lanterns, nickel-plated ; two reflector signal lamps, nickelplated , one bell or gong, nickel-plated ; all necessary wrenches, spanners and tools for working the Truck.

Second-Class—Weight, Complete, About 5800 Pounds—One Hayes Patent Extension Ladder, 60 feet long. One each of the following length hand ladders made of “Oregon pine”: 28, 26, 24, 2r, 18, 16and 12 (roof ladder) feet. The 28, 26 and 24 feet ladders are carried on rollers. The 28 and 21 feet ladders are arranged to splice, making a ladder 45 feet long. Two short-handled hooks; two long-handled hooks; one chain hook ; two crotch poles ;’ two steel crow-bars ; four fire axes, with pike heads ; four pitchforks ; four leather fire buckets ; 150 feet of manilla rope, with tackle and snatch block for hoisting hose ; one oil can ; seven brass hand lanterns, nickel-plated ; two reflector signal lamps, nickel-plated ; one bell or gong, nickel-plated ; all necessary wrenches, spanners and tools for working the Truck.
