LU-DWIG HERMAN,- OF- DETROIT, MICHIGAN.

Letters Patent No. 105,203, dated July 12, 1870.

IMPROVEMZNT IN FIRE-BxTING-UISHERS.

The Schdd'ule referred to in these Letters Patent and making part of the name.

To whom it may concern Be it known thatI, LUDWIG HERMAN, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in an Appar'atus for Extinguishing Fires in Buildings and I do hereby declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and, the letters of reference marked thereon, and being a part of this specification, in which- Y T Figure 1 is an elevationof a store-room fitted with my improvement, showing it ready for work;

Figure 2 is a side elevation of one of the cornice-' brackets, being cross-section of the cornice;

Figure 3 is a cross-section of the fire-proof cornice;

Figure 4 is an elevation of the device as when at wor lligure 5 shows the device closed in the end wall; and

Figure 6 is a plan of l the nozzle.

Like letters indicate like parts in each figure.

The nature of this invention relates to a mcchanism to be applied to stores. and other buildings, to he used-in connection with the hose of a fire-engine, in such a manner that, should a fire take place therein, a sprayof water will be thrown into the room in which it is placed, and that the spraying-nozzle may be caused to travel the entire length of the room, and thereby extinguish the flames without the necessity of any person entering the building.

It consists in the peculiar construction and arrange; ment in the end wall of the building, near one of .the upper corners of the room, of a traveler attached to an endless wire rope, carrying a spraying-nozzle, said rope extending along the top of a fire-proof cornice,

returning through a pipe laid in its lower part to the front. In the big'ht of the rope, at the front, is a pulley-block, provided with a crank or pawl, by means of which the pulley may be rotated, the block to be secured to a stake or ring in the pavement when the device is to be brought into use. When not in use, it is inclosed in a recess in the wall, closed by a suitable door; also, in the construction of a fireproof cornice, as more fully hereinafter set forth.

In the drawing- A represents the end or li ont wall of a building, and

a the transverse joists on which the second floor is laid.

B is a fire-proof cornice, constructed of sheet-iron, in lengths of the proper curvature, inserted in the cast-iron brackets B, secured to the walls of the room.

A pipe, 7), is laid in the lower part of the comice,'for the purpose hereinafter set forth. The interior of the cornice is then filled with any suitable non-conducting material.

- At various intervals in the length of the cornice, a bracket is provided with a carrying-roller, c, journaled in it, as-shown in fig. 2.

O is an opening in the wall A, in front of the cornice, closed by the metallic doorD, which is in two sections, the lower hinged to the wall, and the upper to the lower section. 4

\Vheu closed, the dooris held shut by a spring latch,

11, which may be operated. by a wire extending down the front wall in any convenient manner, so that the door will fall outward when released from the latch.

On the inner side of the lower section of the door is secured a guide-frame, E, in which are journaled two sets of guide-rollers, c c, a curved guide, f; leading to the former.

F is a continuous or endless wire rope, extending along the cornice, and returning to the front through the tube 11, where the under section, passes over the ronersd, and the upper section over the" rollers e in the guide-frame E. The rope should be of such length that it may reach nearly. to the ground toward the middle of the street in front of the building, being rove around a pulley in the block G, which, when brought into use, is connected with a stake or ring, 9, permanently fixed in the pavement by a rope, 71, provided with any suitable means of taking up the slack of the wire rope.

This tightening device and connecting-rope may be carried on the fire-engines, if desired, as the whole device is to be operated by the firemen.

.H is a hollow traveler, secured .to the wire rope, an provided, at the rear end, with a suitable coupling,.by

means .of which the engine-hose .may be connected therewitln. The front part of the traveler is turned to a rightangle with the body thereof, and terminates in aspray-nozzle, H, which rests on and projects be yond the ledge of the cornice.

.W'hen not in use, the block G is stowed in theupper part of the recessO, lyingin a pair of arms hinged therein, in such a manner that, when the door D is opened, their outer ends will drop from the position shown in fig.5 to that shown in fig. 4, when the block will drop to the ground ready to be attached to the stake or ring; when, if a. fire is discovered under way in the store, the wire rope is stretched taut, as

hereinbefore mentioned; the hose of the engine is thencoupled to the traveler, and the pulley rotated in the block G by a crank provided for that purpose; when the traveler will enter the store, passing along the guide-rollers c on the cornice. At this time the en-' gine should force water through the hose, which is discharged through the spray-nozzle toward the opposite side of the room, and, as the traveler'is caused to advance to the rear end of the room, the flames will be extinguished as it progresses.

story, and all or either may be As an ordinary woodencornice would, in many instances, be destroyed before the firemen could reach the building, I construct the cornice as described to resist destruction until water can be thrown on the fire.

If desired, a small perforated water-pipe, I, shown in secti'eninfi s. 2 and 3 connected with the service;

pipeof the building, may be arranged to keep the core nice wet from the time the fire is discovered by opening a cock placed in the front wall of the building.

As shown in figs. 1 and 4, the lower section of the door forms a prop to the upper by resting on ledge in the front wall, and it may, by providing it with suitable springs, be made to take the position shown in these figures as soon as opened.

An apparatus of the construction described should be fitted to one or more of the floors above the lower operated from the rear end of the building, if there be suificient space for the purposeor, if preferred, the device may be so arranged as o be operated from either end.-

It will be seen that the return tube may be dispensed with by having the wire rope extend through purposeset forth.

the rear wall, and the hose drawn through the building from the-end opposite that which it enters.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The endless wire rope F, block G, hollow traveler H, provided with nozzle H,

the guide-frame E, and door D, in connection with the recess 0 and cornice-B, arranged and operatin% substantially as and for the purposes herein set fort 2. A fire-proof cornice, B, constructed in sections of sheet or cast metal; supported in brackets B, and filled with non-conducting material, said cornice being provided with carrying-rollers c and return-tube b, as and for the purpose herein is citied.

3. In connection with af'cornice constructed substantially as described, the water-pipe I, as and for the LUDwIG HERM'AN.
