- WITNESSES INVENTOR m1 TED STATES PATENT oFF C JOHN T. RYAN, or PITTSBURGH, "PENNsYLvANIA, AssIGNoB To MINE SAFETY- APPLIANCE COMPANY, or PITTSBURGH, PENNSYLVANIA, A CORPORATION or PBNNsYLvANIA.
To all whom it may concern: Be itlknown that I, JOHN T. RYAN, resldent of Pittsburgh, in the county of Alleperson surrounded. by noxious ghenyand State of Pennsylvania, have invented a' new and useful Improvement in Regenerators for Breathing Apparatus, of which the following is a specification.
This invention relates to regenerators for so-called breathing apparatus,that is, apparatus for supplying breathable air to a gases or fumes. V e
Apparatus of thekind' described is pro 'vided with a so-called regenerator contain- "any of theair from short circuiting between the inlet and outlet of'the device.
In the accompanying drawing Figure 1 1s in part aside elevation and in part a central longitudinal vertical section throughthe device; Fig. 2 is in part a plan view and .in part a' horizontal section of the device on the line 22, Fig. 1; and Fig. ,3 is a vertical transverse section on the line 33,-Fig. 1.
The improved regenerator comprises a can or canister, preferably formed of suitable non-rusting sheet metal, comprising side walls 1, end walls 2, a top 3 and a bottom 4:-
- This body can be constructed in any suitable side of the chamber in the casing and is suitway, with the parts united in any of the ways well known in the manufacture of sheet metal cans or vessels, and in a manner so that all of the joints are hermetically sealed.
' Located a short. distance above the bottom 4, so as to leave at said bottom. an unobstructed chamber 5- extending from end to.
end of the device, is a suitable screen 6, preferably formed of ,wire gauze of copper or other non-corrosive Wire and which screen extends fromend to'end and from side to Specification of Letters Patent.

ably secured at its edges to the side and end walls thereof, such as being soldered or similarly secured to angle members 7, which are soldered or similarly secured to the walls of the bod-y.v Thespace above this screen 6 is divided .into 2 chambers by means of a vertical transverse partition 8 extending entirelv widthwise of the casing and secured to the side and top walls thereof 1 and having the screen 6 secured to its lower edge, as at 9. The chambers formed by the partition 8 are divided by horizontal screens 10, likewise preferably formed of wire gauze, and located a considerable distance above the screen v6, thus providing spaces 11 for containing the chemical regenerating agent. This chemical may be of openings in the screens 10. These openings are-connected by means of perforated cylinders 16 also preferably formed of wire gauze, and securely fastened to the threaded rings 14 at the top and the plain rings 15 at the bottom.
Engaging in each of the threaded rings 14s is a threaded plug 17, to which is secured a perforated cylinder 18 provided with a bottom 19, and which preferably also is formed of wire gauze. These cylinders are secured such as solder. v
Each of these plugs is provided with a transverse bridge 21 with openings. 22 at each side thereof, and which bridge is provided with a threaded hole 23 for attaching to, the plugs the inhalation and exhalation pipes respectively. I
In the use of the apparatus the granular chemical material is filled into the spaces 11 the cylinder 16, as shown'in Fig. 1. The inhalation pipe is then connected to one of the. plugs 12, and the exhalation. .pipe to the between the bottom screenfi and toppscreen '10, through the cylinders 16, unt1l 'said chambers 11 are substantially full. The plugs 17 are then screwed into the rings 14:
until tight joints are made, a suitable gasket 24 preferably being applied around the plugs. The cylinders 18 pro1ect'down into other of said plugs,'so that in the use of the apparatus air exhaled by the user passes down through one of the cylinders 16, say' the left hand cylinder, escaping through the side walls of that cylinder-in all directions, into the chamber above the screen 10 on that side, whence it will 'passthrough the screen 10, as well as through the bottom 19' of cylinder18, and permeates the material in the left hand chamber 11. passes through the-bottom screen 6 into the passage 5, across to the right hand side, and
up through the screen 6 and the material in p the chamber 11, and up through the screen 10 above said material and into the chamber 25?. and thence through the rlght hand cylinder 16 and out through the inhalation Plpel The construction descrlbed provides for large bodies of regeneratmg chemlcal of substantially uniform thickness, these two partition w1th a bodies being separatedby an imperforate continuous passage underneath the same. Both of these bodies have their entire top and bottom surfaces exposed through the perforated screens or partitions, and the incoming air is distributed over theentire top of the first body of chemical and passes uniformly through said body throughout lts entlre area, and likewlse the upwardly passing current on the rlght hand side passes through the other body of chemical throughout its entire area and collects in the outlet chamber 25 whence it can pass out through the screen cylinder of the inhalation pipe.
. By this construction a very uniform distribution of the air throughout the mass of chemical material is insured, and none of the air can short circuit from the exhalation to the inhalation outlet, but all of it is compelled to pass through two bodies of material and therefore will be thoroughly rcgenerated. None of the fine material of the chemical can pass into the inhalation pipe,
the cylinders screening out any fine material which" would have a tendency to lift in the current of an. Furthermore on account of .the uniform distribution of the air over the Thence it The entire deviceis simple, and can be readily fabricated to provide. air tight joints.
