HENRY CLAYTON, OF PHILADELPHIA, PENNSYLVANIA.

AN ESTH ETlO-IVIASK.

SPECIFICATION forming part of Letters Patent No. 787,828, dated April 18, 1905.

Application filed October 11 1904. Serial No. 228,002.

To fI/Z Z who/It fl may concern:

Be it known that l, TIENRY CLAYTON, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Anesthetic-Masks, of which the following is a specification.

M y invention relates to certain new and useful improvements in anesthetic-n1asks, and more particularly seeks to provide a mask of this character of a very simple, du-

rable, easily-operable, and cheap construc tion which will readily and effectively serve its intended purposes.

In its generic nature my invention includes a wire cage or frame adapted to re eeive a cloth or other absorbent material and means for securely holding said cloth or other absorbent material to said cage, which means can be easily and quickly attached to or detached from the frame to allow for the removal of the cloth, as well as to permit the thorough cleaning and sterilizing of the mask. 7

\Vith other objects in view, which will be hereinafter apparent, the invention also includes certain novel construction and arrangement of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure I shows my invention as applied for use. Fig. 2 is a perspective view of my invention, the cloth being removed. Fig. 3 is a vertical longitut'linal section thereof, the cloth being shown in position in dotted lines. Fig. l is a detail face view of a portion thereof. Fig. is a detail cross-section on the line 5 5 of Fig. 3. Fig. 6 is a plan of a slightly-modi'fied form of my invention. Fig. 7 is a detail cross-section on the line 7 7 of Fig. 6. Fig. 8 is a detail plan view of another modification of my invention. Fig. 9 is a similar view of a further modification of my invention. Fig. I0 is a detail cross-section on the line 1U 10 of Fig. 9.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all the figures, and by particularly referring to Figs. 1 to 5, which illustrate the preferred form of my invention, it will be seen the cage or frame A consists of awire base member 1, bent into the desired shape and comprising the body portion 1, the neck portion 1", and the finger-engaging portion 1 The neck portion 1" is provided with S-shaped bends l" 1, arranged parallel with each other to form a locking-momber-receiving portion for the purpose presently explained. The neck 1 terminates in a bent member or book portion 1, as clearly shown in Figs. 1, 2, 3, and 4. The base member 1 is composed of a single piece of wire bent into the desired shape, and the ends thereof are secured together, as at 1, by welding, soldering, or any other suitable means.

1" designates the finger member for readily permitting the locking member 3, hereinafter again referred to, to be released from the cage member to allow of the removal of the fabric.

2 2 designate a plurality of wire members bent into a semicircular shape and disposed parallel in pairs to form the fabric-receiving or cage portion of the mask, and the said members 2 2 are secured at their ends 2 2 to the frame member 1. by being bent around the same, and the said ends may be welded, soldered, or otherwise made fast to the member 1.

The wire members 2 2 where they are sccured to the base 1 are bent to form locking-shoulders 2 2 for the purpose presently explained.

3 designates what I term the locking memher, and the said member 3 consists of a wire member bent into substantially the same shape as the wire member 1, and the said wire member 3 is bent to form engaging bearing portions 3 3, merging with angled portions 3 3 to cooperate with the S-shaped bends l 1 of the member 1, whereby to form, as it were, a hinged connection between the members 1 and 3, as clearly shown in Figs. 2, 3, and 4 of the drawings. The wire 3 has its ends joined, as at 3, by welding, soldering, or otherwise in the same manner as the ends of the wire 1 are joined.

So far as described it will be seen the fabric 0 is first placed on the cage A, (see Fig. 1,) after which the locking member 3 is placed in position with its bearing portion 3 interlocked with the S-shaped bent portions 1", (see Figs. 2 and 3,) and the said member 3 is then sprung over the wires 2 2 until the locking member 3 passes the shoulders 2 2 and abuts against the end 2 of the said member 2, as is clearly shown in Fig. 5. This securely holds the fabric C in position. The mask is then placed over the mouth and nose of the patient in the manner shown in Fig. 1 and saturated with a suitable anesthetic by dropping the same upon the fabric from any suitable dropping bottle or receptacle. The portions 3 3 of the locking member 3 serve to prevent lateral displacement of the said member 3 with respect to the member 1.

In Figs. 6 and 7 I have shown a slightlymodified form of my invention, in which the member 1 is provided with S-shaped bent portions 1 1 which are arranged in a horizontal plane instead of vertical planes, as is the case in Fig. 1. In this form of my inven tion also the locking member 3 does not have its ends joined together, as is the case in the preferred form of my invention; but the said member 3 has its ends bent to form hooks 3 3 which hooks cooperate with the bearing portions of the S-shaped bends 1 1. In this form of my invention the finger-piece 1 is not formed in the member 1, but the locking member 3 is provided with a fingerpiece 3", as shown, and for the same purpose as the finger-piece 1 in Fig. 2. V

Fig. 8 shows a still further modification of my invention, which is substantially the same as that shown in Fig. 6, excepting that the parts are of a different shape. The locking member 3 in this form is also provided with hook portions 3 3 to cooperate with ghe S-shaped bent portions 1 1 of the mem- In Fig. 9 I have shown a further modification of my invention, which is generically the same as that shown in Figs. 6 and 8, with the exception that in Figs. 6 and 8 the S-shaped portions 1 1 are formed at the junction of the neck portion 1 with the body portions 1, while in Fig. 9 the body member 1 where it joins with the finger-piece 1 is bent to form bearing portions 1 1 to receive the hook ends 3 of the locking member 3, and in this form of my invention the locking member 3 has a hinged connection with the member 1, as has also the locking member 3 in the form shown in Figs. 6 and 8.

By detachably holding the locking member 3 to the member 1 the said locking member can be readily detached from the member 1 to allow of the parts being thoroughly sterilized and cleaned. i

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my inven tion will be readily apparent to those skilled in the art to which it appertains, and I desire it understood thatslight changes in the detail construction and arrangement of parts may be made without departing from the scope of the invention or that of the appended claims.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is-
