LAWRENCE P. LEONARD, OF ST. CLOUD, MINNESOTA.

FRESH-AIR-TREATMENT APPARATUS.

Specification of Letters Patent.

Application filed May 26, 1908.

Patented March 80, 1909.

Serial No. l85,0'71.

To all whom it may concern:

Be it known that I, Lawrence P. LEON- ARI), a citizen of the United States, residing at St. Cloud, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Fresh-Air- Treatment Apparatus, of which the following is a specification.

My invention relates to devices for treating patients suffering from tuberculosis, pneumonia, anemia, etc., with fresh air.

On Feb. 18, 1908, there was granted to me United States Letters Patent No. 879,391, for day treatment of patients with fresh air in which only the patients nose was covered by the end of the inhaler but he was required to lie in one position to keep the device in lace.

The invention hereinafter described and claimed is particularly designed for use in treating patients at night and is constructed to inclose the patients head so that the patient can turn in his sleep and still receive the benefits of the treatment.

The construction and operation of my improved apparatus for fresh air treatment is described hereinafter and illustrated in the accompanying drawings in which a room and the patient lying in bed with my improved apparatus in position, Fig. 2, a cross-section of the joint by which the induction tube is secured to the window, Fig. 3, a front view, on an enlarged scale, of the diffusing chamber, Fig. i, a side view, Fig. 5, a'longitudinal sectional view thereof, and Fig. 6, a view showing an attachment for sliding windows.

In thedrawings similar reference characters indicate corresponding parts in all the views.

In the form shown in Fig. 1 my device is shown in connection with a window A having a sliding sash B and a swinging storm sash B controlled by means of a latch C. The device may be attached to the sliding sash or if desired a separate sash D may be used as shown in Fig. 6 and inserted under the lower sliding sash B or above the upper sash as desired, the position of sash D being fixed by the height of the window here the window is not conveniently placed for attachment of my device it will be apparent-that a hole may be made in the outer wall of thebuild inp; to accommodate the end of the induction tube and filter, hereinafter described, it not being considered to be necessary to illustrate this construction.

Secured to sash B or D is a plate 1 having' a hole 2 therein opening to the outer air and with a socket surroundingthe hole to receive the spherical enlargement t on the end of induction tube 6 indicates another plate having a hole 7 therein to receive tube 5 and upset around said hole as shown at S to form a socket to fit the spherical enlargement t.

9 indicates bolts secured to plate 1 having eye-loops 9. and 10 hooked rods mounted on plate 6 to engage said eye-loops 9, the ends of said rods 10 beingthreaded to receive wine nuts 11. This construction forms a ball and socket joint for the receiving end of induction tube 5 so that the tube may be adjusted within certain limits to suit the position of the patient.

12 indicates a hook secured to the casing of the window A or other convenient place and 13 a spring: secured to the hook and to tube 5 to support it and still permit movement of the tube to accommodate itself to the movements of the patient.

The dili'using chamber consists of a cylindrical shaped casing 14fv made of a heavy air-proof fabric such as canvas and is secured to the inner end of tube 5 by means of a strap 15 run through guides 16 on the upper end of easing l t. The casing 1% is made preferably larger in diameter intermediate of its ends as shown at 17 andhas a hoop 18 secured at the large portion 17 and other hoops 19 between the upper end of casing 1 and the enlarged portion 17 so as to hold the upper portion of the casing distended.

20 indicates bands of elastic material secured longitudinally of the casing between its upper end and enlarged portion 17 and adapted to normally pucker the upper end of the casing so as to prevent it from sagging when not fully extended by the position of the patient. A hoop 21 is also secured to the lower edge of easing id to hold it distended.

2 indicates a hood secured to the lower edge of casing 14: by means of lacing strings, buttons or other detachable fastenings said hood being made of a softer fabric than that of said casing, is opened at the front as shown at 23 to receive the head of the patient, and has flaps 24: with any temporary fastening means such as button holes and buttons to fasten them across the patients throat. To protect the top of the patients head from the air the hood 22 is continued inside of the casing as shown at 25 to engage the forehead of the patient.

26 indicates pockets on the inside of the casing 14: to hold resinous material or other medicinal substance with which it may be desired to impregnate the air.

27 indicates a window of sheet celluloid or other transparent material to permit the patient to see what is going on around him and 28 an opening containing a gusset 29 and closed by a craw-string 3O engaging button 31 or other fastening means to permit the patient to insert his hand and a handkerchief to reach his mouth and nose.

32 indicates a damper in tube 5 controlled by rods or other means 33 to regulate the ingress of air, said rods 32 being arranged conveniently to the patient as shown in Fig. 1.

The induction tube 5 may be made of any suitable material but I prefer to use wood fiber, which is a nonconductor of heat, so as to prevent chilling the room.

In order that the air may be cleared of insects, dust, and other small particles floating therein before entering the induction tube 5 I secure a filter over the mouth of the tube consisting of a strip of wire mesh screen 34 covered by a layer of filtering cloth 35 such as mull or silk. In the drawings I have shown the filter secured by means of bolts 9 to the outside of plate 1 but any other method of securing it in position may be substituted if desired.

Having thus described my invention what I claim is 1. In a fresh air treatment apparatus, in combination with the window, a perforated plate secured thereto having a socket, the induction tube made of rigid material and having a spherical enlargement on its end to engage said socket, and means to secure said enlargement in the socket.

2. In a fresh air treatment apparatus, in combination with the window, a perforated plate secured thereto having a socket, the induction tube made of rigid material and having a sphericalenlargement on its end to engage said socket, and another perforated plate formed with a socket to engage said enlargement and adjustably secured to the first-mentioned plate.

8. In a fresh air treatment apparatus, in combination with the window, a plate secured thereto having a socket, the induction tube having a spherical enlargement on its end to engage said socket, another plate formed with a socket to engage said enlargement, hooked rods secured to one plate, and rods having eye-loops to engage said hooked rods secured to the other plate.
