FIRENIANS HELIVIET SPECIFICATION forming part of Letters Patent N 0. 752,266, dated February 1K6, 1904,

Application filed December 6, 1902. Serial No. 134,096. (No model.)

To a/ZZ whom, t may concern,.-

Be vit known thatI, Cnozrnn T. THOMPSON, a citizen of the United States of America, residing at Cripplecreek, in the county or' Teller and State of Colorado, have invented certain new and useful Improvements in Helmets and Smoke-Excluders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reierence being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specication. Y

My invention relates to a helmet and smokeexcluder for the use of tiremen and others who may have occasion to enter burning buildings or otherplaces where the smoke or noxious gases, or both, must be kept from the mouth and nostrils in order to make it possible for the person to remain and perform any eiiicient service.

The invention is provided with receptacles for chemicals, the said receptacles being in communication with the space inclosed by thel device, whereby the impurities of the air resulting from breathing are neutralized or in some way changed, thus enabling the user to work for a considerable time or indeinitelyy when cut od froml a supply of pure or atmospheric air. The nature of thechemicals employed, except as above explained, will not be set forth in this specification, as nothing isk claimed thereon in this application.

Briefly stated, my improved device consists of a garment attached to an ordinary hat or' helmet, the latter being of the type worn by firemen. Instead of this specific construction of hat or helmet, however, any other suitable or desirable construction for covering the head may be employed. The garment or jacket is attached to the hat or helmet so as to exclude the smoke, and it extends downwardly around the body of the wearer to the waist, or thereabout, where it is secured by means of a belt, tightly buckled to exclude the smoke from below. Springs are interposed in front of the belt, being located in a pocket to permit a 4limited degree of elasticity,lwhile holding the garment or jacket tightly against the body of the wearer. Above the belt andinside of the garment or between the latter and the body oi' the wearer are located a number of receptacles adapted to hold some of the chemicals employed, suiicient space being left to allow a free communication between the receptacles and the mouth and nostrils of the wearer. Another receptacle is exteriorly located and connected in front with the space inclosed by the garment by a suitable tube or conduit, its object being to permit the passage of a gas from the outer receptacle to the space within the garment.

IHaving brieiiy outlined my improved device, as well as the function it is intended to perform, I will proceed to describe the same in detaiLreference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is an elevation showing my improved device in use. Fig. 2 is a section taken through the garment. Fig. 3 is an enlarged detail view of the window located in front of the garment, through which section taken' through the garment where the Vsprings are located. Fig. 7 is a detail view,

partly in section, illustrating an electricillu- `minating device, shown on a larger scale than in Figs. 1 and 2.

The same reference characters indicate the same parts in all the views.

Let the numeral designate the hat or helmet, to the rim of which on the under side is attached the upper edge of the garment 6, as shown at 7, by means of suitable fastening devices whereby a perfectly tight joint is made. This garment may be made of canvas rubberlined or any other suitable or desirable material which is impervious to Water and smoke and not readily ignitible. It should also be of sutlicient stiifness to stand out well from the face and head of the wearer below the rim ofthe helmet, and therefore not readily collapsible. Below the rim of the helmet and directly in front of the eyes of the wearer is located a sort of window or transparent device 8, which covers an opening in the garment and is secured thereto in any suitable manner. This device is shown in detail in Fig. 3. It may be composed of isinglass or mica or other suitable transparent material. It is preferred that this material should have sufficient toughness so that it will not break easily. It must of course possess the property of transparency to a suiiicient degree for the purpose. As shown in the drawings, this window is provided'with wires 8, which protect the transparent material. The wires `are. attached to metal end pieces 8, which are attached to the garment and form a sort of sash to hold the window 8 in place. y

The lower part of the garment or jacket is provided with loops 10, through which a belt 12 may be passed. To the inside of the garment in front is attached a piece of material 13, forming an inside chamberlor pocket, in which are located a number of coil-springs 14, causing this portion of the garment to yield to pressure from within or without. This yielding portion of the garment is located in the Zone of the belt and engages the body `of the user in front where the belt buckles.

Between the belt and the window and located inside of the garment in front is a number of receptacles 15, open at the top and of the construction best shown in Fig. 5. Each of these receptacles is a box-like device having an upwardly-projecting flange 15, which is riveted or otherwise suitably secured to the garment in front. Projecting rearwardly from the body of the receptacle is a sort of wire or rod forming a brace 15, which is shaped to conform to the curvature of the body of the wearer. This brace engages the body, as shown in Fig. 2. Between the body portion of the device and the brace is an open space to permit the free circulation of air or gases within the inclosed chamber. To the upper back portion of the garment is attached a receptacle 16, from which leads a tube 17, whose extremity remote from the receptacle communicates with-the interior of the garment in front, as shown at 18. v This receptacle 16 is preferably made of heavy cotton'web rubber-lined and air-tight, the material being of suicient strength to withstand one hundred pounds pressure, or thereabout.

All of the joints of the device or the points of attachment of exterior parts are so formed as to exclude the smoke and surrounding gases,

^ thus making the garment or the combined helmet and jacket perfectly air-tight.

The receptacle 16 is detachable, having straps 16, provided with holes to permit the entrance of buttons 6, attached to the gar-l ment exteriorly. This receptacle is provided with a valved inlet 16c at the top for the introduction of its contents. This inlet should be tightly closed after filling to prevent the escape of gasexcept by way of the conduit 17.

Attached exteriorly to the garment or jacket in front is an electric lamp 19, mounted on a storage battery 20, which supplies the current. This battery is attached to the garment by means of a buttoned strap 21. The lamp is surrounded by a reflecting-hood 22, open in front to permit the escape of rays of light in front of the wearer.

The arms of the garment are tight at the wrist, being composed of some suitable elastic material 6". (See Fig. 1.)

From the foregoing description the use and operation of my improved device will be readily understood. The jacket is slipped over the head of the wearer and drawn down until the helmet is in place on the head. The belt is then buckled around the waist sufficiently tight to exclude smoke and gases. Itis assumed that before the jacket is put on the chemicals to be employed in purifying the air have been placed in the various receptacles. The head and body/of the wearer as far as the waist are then enveloped and entirely protected by the air-tight jacket and helmet, enabling the user to work with impunity in places where it would otherwise be impossible for him to remain on account of smoke and gases, or both.

Having thus described my invention, what -I claim is- 1. In an apparatus of the class described, the combination with a helmet, of a smokeexcluding jacket attached to the helmet and arranged to be fastened around the body of the wearer and provided with a receptacle on the inside, substantially as described.

2. The combination with a helmet, of a jacket whose upper extremity is attached to the helmet and whose lower extremity is provided with a fastening-belt, and receptacles attached to the jacket between the helmet and the belt and located on the inside of the garment for the purpose set forth.
