Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed Juno 10,1904. Serial No. 211,937.

T0 :all whom, t may concer-77,:

Be it known that I, WILLARD R. GREEN, a citizen of the United States, residing in Muscatine, in the county of YMuscatine and State of Iowa, have invented certain new and useful Improvements in Absorbent Bandages, of which the following is a specification.

This invention relates to absorbent bandages and one of the objects and advantages sought to be obtained by means of the present improvement is to provide for the manufacture of the bandages at a low cost and for the use in such manufacture of materials of a low cost and employed in a minimum quantity. For this purpose and also to provide for a high degree of receptivity and distributive capacity, but especially to reduce the amount of absorptiveA material which would otherwise be required in a bandage of a given and proper bulk or size, I' employ such a con-` struction of the component members of the bandage as will secure a considerable proportionate amount of open space in the nature of chamber-space or cell-space, these spaces serving in part as receptacles for the quick reception of a considerable amount of fluid or semifluid materialand also serving as distributive means for transmitting the same more gradually to the absorptive portions of the bandage. Also such space or spaces will in general serve to finally receive and retain considerable quantities of material which would otherwise have to be taken up by the absorptive or fibrous portions of the bandage.

In the drawings accompanying and forming a part of this specification, Figure l is a perspective view of an absorbent bandage made in accordance with my present improvements. Fig. 2 is a cross-sectional view taken in line 2 2, Fig.` 1. Fig. 3 is a longitudinal sectional view taken in line 8 3, Fig. 2, showing the parts as seen from the right hand in Fig. 2. Fig. 4 is a plan view of a portion of the bandage with the surface sheet or sheets removed. Fig. 5 is a view similar to Fig. 3, taken in line 5 5, Figs. 2 and 4. Fig. 6 is a view illustrating a preferred construction of one of the component members of the bandage. Fig. 7 is a perspective view illustrating the application of an absorbent to one of the members, and Fig. 8 illustrates a different form thereof.

Similar characters of reference designate corresponding parts throughout the several figures.

The bandage may be made up by having a suitable cover-sheet 30, in which the receiving and absorption materials and members are placed, and which cover-sheet may have its end portions 31 32 folded one upon the other and secured by some suitable securing means-as, for instance, fasteners or stitches, designated in a general way by 23S-which ends may form securing members to secure the bandage in place or to the part to which it has been applied'. The coverssheet isA so disposed upon the bandage as to leave a suitable receiving-op ening, which may, if desired, be covered with some suitable material or fabric (designated in a general way by 34) which is readily penetrable by the material for absorption.

In absorbent bandages of this class it is desirable in some cases to provide a chamberspace Within the body of the bandage and to so construct the bandage as to normally maintain said chamber-spaces free of obstructions other than the fluids or semifluids which may be taken up by the bandage. In accordance with my present improvement this object is attained by an improved organization and construction of the bandage, of which a preferred form is illustrated in the drawings.

In a general way the bandage (see Figs. 2 and 4;) may be said to be divided longitudinally into three principal zones 5, 6, and 7. The middle Zone 6 consists principally of open chamber-spaces, while in the adjacent side zones 5 and 'Z are located the principal abrorbent or receiving members of the article. The preferred construction and arrangement of one of these longitudinal receiving members is indicated in Fig. 3. The absorbent material of suitable fiber stock of the proper proportion and consistency in a strand or band, preferably of a flat shape, as indicated at S, Fig. 2, is bent or folded upon itself upwardly and downwardly, the alternate bends 9 and 10 coming to the upper side. of the bandage, while the alternate immediate bends 9/ and l0 come to the lower side, and the strand 8 so folded is separated and supported by the individual members or elements 1l and l2, thereby holding said rcceiving member normally in proper form and supporting the same against undue com- IOO pression or collapsing within the bandage. For the purpose of preventing the sidewise collapsing of the bandage said supporting members 11 and 12 may be extended across the bandage to the opposite side thereof, as indicated at 13, Fig. 2. A further feature relates to the manner in which these individual side-bracing members 11 and 12 may be connected together in a series. The manner in which I prefer to accomplish this result when this feature is to be embodied in the bandage is illustrated in Fig. 6, showing a strip preferably cut from a sheet of paperstock of suitable thickness and texture-- such, for instance, as so-called soda-stock,7 this being of a relatively lirm but absorbent quality. In some cases, however, a thinner and more firm paper or sheet material may be employed, and the stabilityT of the same may be maintained by suitably waterproofing-as, for instance, by treatment with an asphaltum preparation. By bending or folding the blank represented in Fig. 6 along the dotted lines 14 this member will then, as seen in edged view, take the form represented in Fig. 5. Comparing Fig. 3 with Fig. 2, it will be seen how the folding of the blank for the side-bracing and chamber-forming member will bring the projecting ends 11 and 12 in Fig. 6 into the positions indicated in Figs. 2, 3, 4l, and 5 and at the same time form with the longitudinal middle portion of such member a series of open chambers 15 and 16, the alternate chambers 15 of which will open toward the top of the band age, while the intermediate alternate chambers 16 will open toward the bottom of the bandage. This arrangement also provides an open space 17 along the top of the bandage connecting with the alternate upwardly-opening chambers15.

The several parts of the bandage assembled as above described constitute a combined receiving and distributing member having absorptive portions and chamberp space portions, these chamber-spaces communicating directly with. the vertically-disposed folds of the absorbent member. In addition to the portions just described I prefer to employ in practice an outer layer of absorbent 'librous materialsuch, for instance, Vas vegetable fiber of a loose formation-for inclosing the receiving and distributing member at the bottom and along the sides thereof. This additional absorbent material is indicated at 20.

The member constituting the side brace and chamber-forming member has absorbent material at the sides or between its edges and the sides of the bandage to act as pads.

In Figs. 8, 41, and 5 the absorbent material 8 is shown as having its bends pass around each projecting end 11 and 12, so that the strands of such absorbent will occupy each of the cell or chamber spaces at the edges of the cell-space member. In Figs. 7 and 8, however, the strands pass through each alternate chamber, thus leaving intermediate chambers which are not filled or partially filled with the absorbent material, thus leaving chamber-spaces for the reception of the materials for absorption and receptacles in which the unabsorbed portions may remain.

It is desirable in some forms of bandage that the same shall be maintained to some extent from longitudinal compression, and in carrying out this feature the member carrying the cell-spaces may be made of a strip of some suitable material slitted inwardly from the sides and folded up, as shown in Fig. 8, wherein the portions 22 will be bent transversely to the portions 23, and so not only produce cells in the center of the member, but will prevent the longitudinal compression thereof and also add to the stability of the structure as a whole. In some cases it may be desired to perforate certain portions of this cell-space member, as at 24 or otherwise, as occasion may demand, and such cell-space or framework member may be constructed of perforated sheet-form material-such, for instance, as some kind of paper or veneer stock- 0r as a suitable sheet material therefor a wire-cloth of medium quality and size of mesh may preferably be employed.

In Fig. 7 it will be noticed that there are provided a series of upwardly opening trough-like chambers 25, interspersed by intermediate cell-spaces 26, which are open at the top and bottom and the outer side, and which cell-spaces have between them other cell-spaces 27,which are closed at the top and open at the bottom-that is, assuming the top and bottom to mean, respectively, the portion directed toward the opening of the bandage and the portion directed toward the body of absorbent material. In the form shown in Fig. 7 the strands of absorbent pass over and under the trough-chambers 25 and through the cell-spaces 26. Thus a large amount of receiving and distributing chambers are provided and the structure is materially lightened in weight and the amount of absorbent material necessary to produce a bandage of a given size reduced or lessened.

In some cases the receiving-sheet may be dispensed with, in which case the receivingchambers are open to directly receive the material for absorption.

It will be noticed in Fig. 7 that the bracing portions 22 are so disposed that they will prevent the collapsing of the said member at the lower side-that is, the side shown toward the bottom of the present drawingsso that there will be little inclination for collapsing; but as each alternate trough is open at the portion toward the top of the drawings it will be apparent that a transverse roo IIR

bend in that direction will be greatly facilitated by this form of construction.

I do not claim herein, broadly, absorbent material folded upon itself, with the layers disposed perpendicularly to the bandage, or an absorbent sheet of material folded upon itself in connection with means for separating the several folds, as this constitutes in part the subject-matter of my copending application, Serial No. 212,278,1iled June 13, 1904; nor do I claim herein strands running crosswise of each other or twisted strands, as this constitutes in part the subject-matter of my copending application, Serial N o. 212,897, filed June 16, 1904; nor do I claim, broadly, herein a side-bracing member, as this constitutes in part the subject-matter of my copending application, Serial No. 211,926, led June 10, 1904; nor a cellular side-bracing member, as this constitutes in part the subject-matter of my copending application, Serial No. 211,931, filed June 10, 1904.
