Specification of Letters Patent.
Patented Feb. 2, 1909.
Application filed April 10, 1908. Serial No. 426,190.
To all whom it may concern: A I
Be it known that I, WILLIAM EDWARD GARFORTH, a subject of the King of Great.
Britain, residing at Normanton, Yorkshire, England, have invented a certain new and useful Improved Respiration Apparatus for Use in Coal-Mines and other Places,'and of which the following is a specification.
This invention relates to respiration apparatus for use in coal mines and other places, the apparatus dealt with being of that known type in which the wearer has a tlghtly fittlng face-piece covering the mouth and nose; from the interior of this face piece the expired or usedair is conducted to a regenerator case which contains caustic alkali, and from thence the purified nitrogen is conducted to a storage bag, and from this storage bag it is admitted to the facepiece for re-use bythe wearer. There is also in this known respiration apparatus, a supply of oxygen, stored in a cylinder or of this oxygen. is also conducted to the said face-piece.
Now the object of the present invention is to provide improved means by which those parts of the apparatus which the wearer has to carry upon his body-and some of which are of considerable weight shall be so arranged as to cause the least possible fatigue and inconvenience, as well as to impede as little as possible the wearers movements, and at the same time to so provide that the wearer will always, each time the apparatus is applied, have all the' parts that he carries on his body exactly inrthose positions in. which he has been accustomed or practiced to carry them.
According therefore to the present invention, I employ a flexible jacket of any suitable material such as leather, which besides serving the ordinary purposes of such a garment, acts as a foundation upon which the various parts of the apparatusare and remain arranged and fixed, and with which the storage bag for the purified nitrogen is constructed. The jacket is provided with means by which the regenerator case is fixed to the back, and two oxygen storage cylin ders are employed which are connected by a pipe, and these storage cylinders each being of some considerable weight, are arranged one upon each side aboutthe hips, while the storage bag for nitrogen is composed, as usual, of a flexible indiarubber case but is permanently fixed in'the rear of the jacket,
and the various pipes which proceed from the face-piece to the parts of the apparatus carried upon the jacket are capable of being detached from those latter parts, so that with very great rapidity the wearer can put on the jacket with all the parts conveniently arranged, and then the pipes to the facepiece can be connected up.
The invention is described in detail with reference to the example of construction shown on the accompanying drawings, whereon is illustrated a respiration apparatus of the type first stated in this specification, but constructed with certain improvements which are described in the specifications of patent aplications by myself of even date herewith. It is to be understood, however, that the present invention does not deal with any particular and specific construction of the before-stated type of respiration apparatus, but it does deal with the particular arrangement, disposition and mode of fixture of certain parts of such apparatus, viz., to the formation of the oxygen cylinders so that they can be carried upon each side'of the person about the hips, and to the guard wings on-the regenerator case, to the location of the storage bag, and to the fixture of all these parts upon a jacket, so that when a person has applied this jacket, he has then all these parts arranged in their proper positions. Hence, it is clear that any known form of respiration apparatus of this type can be equally well arranged to be applied and be constructed according to the present invention.
. In the accompanying drawings, Figure 1 is a left-hand side elevation showing the parts of the apparatus assembled in position. Fig. 2 is a front view of the apparatus shown inFig. 1, and Fig. 3 is a rear View of the apparatus shown inFigs. 1 and 2.
Referring to the drawings, the headgear is similar to that described in the specifications of my patent applications of even date, and consists of a face-piece l which communicates with two passages in a double tube 2 passing over the head-cap 3, the tube 2 being forked at its rear end and one of its branches connected by a detachable joint 39 with a flexible pipe 4; the pipe 4 communicates with the regenerating case 6 to take the used air to said case, while two flexible pipes 7, connected to said case by detachable joints, convey the purified nitrogen to a storage bag 8, and from thence a flexible in the 1'0111' portion of 1'19'01161'111'05 case to contain ige s1de of 511111 in posh two pipes proece. means "for 110- 1110 -3 and nitrog;
