UNITED STATES NAPOLEON LAMBERT, OF ROLLA, NORTH DAKOTA.

RE SPIRATOR.

Specification of Letters Patent.

Patentedj-Tan. 5, 1909.

Application filed June 3, 1908. Serial No. 436,478.

To all whom it may concern:

Be it known that I, NAPOLEON LAMBERT, a citizen of the United States of America, residing at Rolla, county of Rolette, in the State of North Dakota, one of the United States of America, have invented certain new and useful Improvements in Res irators and I do hereby declare that the fol owing is 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.

The present invention relates to respirators, and more articularly to means for purifying and coo ing the air drawn or forced through the several parts of the device.

Broadly speaking, it comprises a screen box, a bell divided into compartments and located within the screen box, respiration tubes separatel connected to the compartments of the be means for purifying the air passing through the several respiration tubes, and means for cooling the air passing through the respirator.

In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several views of the drawings, like reference characters designate the same parts. I

In the drawings: Fi ure 1 is a side elevation of the device, part yin section; and, Fig. 2 is a detail sectional view on line 22 of Fig. 1.

The invention is particularly adapted for use in hospitals and sanitariums where pure dry air is required in the treatment of certain kinds of diseases. The device comprises a box 1, of considerable size, which is adapted to be secured to the wall of a building in any suitable manner. The interior of this box is thoroughly lined with screen 2 of a very fine mesh, gauze, or similar material, adapted to exclude all dust and other injurious matter from the interior of the box. Doors 3 are provided in the several faces of the box, which may be opened, when desired, to allow admission of air to the interior through the screen material 2. In order to allow respira tion of the air in the box 1, a bell is provided. This bell is placed within the box and divided into two separate compartments 4 and 5 b a partition extending the length of the belll In the ends of these two compartments are fitted inhalation and exhalation tubes 6 and 7 respectively. To the outer end of the inhalatlon tube is coupled a short flexible rub- 1 ber Y tube 8, the branches of which are provided with nipples 9 for insertion into the nostrils of the atient. The exhalation tube is provided wlth a broad, flat silver mouth piece 10, having a flange 11 and a rubber guard 12. piece from slipping from the mouth of the patient, and the rubber guard acts to limit the insertion of it.

In order to thoroughly purify the air drawn through the tube 6, a small cup-like receptacle 13 is provided, adapted to contain a purifying medicament which may pass freely from the cup to the air in the tube 6 by way of the short connecting tube 14.

The air exhaled b the patient should also be thoroughly puri ed, and, to this end, a connection, by means of the pipe 15, is made between the medicament receptacle and the exhalation tube 7. Thus, it will be noticed, that both the air inhaled and that exhaled, is thoroughly purified by the same device.

Of course, it is clear that inhalation through the tube 7 should be prevented. To this end, a small one-way flap valve 16 is provided in the short flexible connection between the mouth iece 10 and the tube 7. This allows air to e exhaled through the tube, but does not allow inhalation through the same.

In order to facilitate recharging of the receptacle 13, a particular construction has been resorted to. This comprises a conical cap 17 threaded onto the lower end of the pipe 15, and provided with exterior threads around its base adapted to engage the interior threads around the upper rim of the receptacle 13. Thus, the cap and receptacle may be readily se arated when desired.

In very warm 0 imates, or during the hot months of the year, it is often desirable to cool the air passing through the tubes 6 and 7. To this end, a cooling chamber 18 has been provided. This chamber surrounds the tubes, and is adapted to contain ice or other refrigerants for lowering the temperature in the tube.

It is clear that many changes may be made in the construction of the several parts of the device, many rearrangements of these parts, many other combinations of them and many substitutions for them, without in any way departing from the field and scope of The flange'prevents the mouth the present invention, include all such Within this application, wherein only a preferred form has been shown and described.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A res irator comprising, a box, a bell mounted tierein and divided into compartments, inhalation and exhalation tubes connected to the compartments of the bell, means for cooling the air drawn through said tubes, and means for purifying the air passing through said tubes.

2. A respirator of the character described comprising, a box, a bell comprising a plurality of compartments and mounted in said box, exhalation and inhalation tubes connected to separate compartments of said through the said tubes, and means for purifying the air passing through said tubes.

3. In a respirator of the character described, a box, a bell mounted therein, a partition in said bell dividing the same into compartments, inhalation and exhalation tubes connected to the compartments of said bell, means for cooling the air passing through said tubes, and a single means for purifying the air passing through each of the aforesaid tubes separately.

In Witness whereof I have hereunto set my hand in the presence of tWo Witnesses.

NAPOLEON LAMBERT.
