APPARATUS FOR FOLDING GAUZE FOR SURGICAL DRESSINGS, @c.

Specification of Letters Patent.

Patented June a, 1918..

Application filed April 6, 1918. Serial No. 226,918.

To all whom it may concern Be it known that I, LULU H. Mnnnn, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city an State of New York, have invented certain new and useful Improvements in Apparatus for Folding Gauze for S urg 1- cal Dressings, &c., of which the following is a specification.

My invention, while applicable to var1ous other uses, is designed more especlally to afford simple, cheap, but effective means whereby gauze for surgical dressmgs may be conveniently and quickl unwound from the commercial bolt and fo ded evenly into superposed layers which may be cut into sultable lengths with accuracy and wlthout waste, as hereinafter more fully set forth.

The invention consists in the specific combination and arrangement of parts described and claimed,distinctive features being the means for prescribing'the length of old; the feed of the gauze from the bolt to the folding table; the adjustment of the length of fold, and the holding of the folds taut, etc.

In the accompanying drawings, Figure 1, is a plan of a gauze man1pulating and cutting table or board embodymg the emential features of my invention,-the

gauze being broken away in part for clear-- ness of illustration;

Fig. 2, is an elevation of the parts shown in Fig. 1;

Fig. 3, is a sectional detail showing an elevation of one extremity of one of the pm racks;

Fig. 4, is a sectional detail showing one extremity of the spreader frame.

The commercial bolt of gauze is flat, and either of full width or folded double around a flat card board. when the full width bolt is to be manipulated the rotatable spindle a, is dispensed with and the full width bolt laid on the table if, a suitable distance behind or to the right of the guide bar 9, which is mounted on the under side of the cross bar 0, supported b the end standards a, s, the lower ends 0 which are provided with screw or equivalent clamps s, s. The uide bar 9, is preferably a roller the ends 0 wh ch restin sockets c (one of which is shown in Fig. 4) on the under side of the cross bar 0. The roller facilitates the feeding of the gauze to and between the pin racks 1", and lessens frictional resistance to such feed. I

"when not desired for immediate use.

5 L from the rac When the bolt is of the half width type, the card board core is removed, the spindle a, inserted through the bolt in lieu thereof, and the spindle a, mounted upon and'between bifurcated ends of the standards a, a, which are' clamped to the edges of the table, so as to be readily removed therefrom When the folded bolt is thus mounted it is opened up to full width before being first fed to and over the guide 9, after which it will unfold itself as drawn'over-said guide 9.

The pinracks r, r, are strips of wood or other suitable material of a length equal to the width of the table It, and are formed at each extremity with a screw clamp 1", or equivalent, by means of which they may be readily adjusted along the length of the table t, the edges of which are formed with,

coincident scales is, (see Fig. 1) so that the alinement of the racks r, transversely across the table may be readily and accurately attained,the distance apart of the two racks r, being of course regulated according to the lengths of folds desired.

The pins project upward vertically bars 7', and are sufliciently close and numerous to insure a firm hold on the bights of the gauze fabric f, as folded over from one rack and set of pins to the other. This action is illustrated in exaggerated form in Fig. 2, but illustrates the principle and function involved. The bights b, in the fabric 7", are formed carefully and gaged by the width of the rack bars 1', so that accurate alinement is readily attained. This insures uniformity of width of dressing strips when the fabric is out between the rack bars, which cutting operation is performed when a suitable number of layers of the fabric 7, are superposed one upon the other. I

The cutting may be efl'ected by any known or suitable means, as an electrically driven cutter, shears, or the like as may be found most convenient or expedient,and the folded fabric may be marked for the purpose of cutting by means of a ruler extended transversely across the folds and gaged in position by means of the aforesaid scales is, k, at or adjacent to the edges of the table 16.

The numerous pins p, hold the fabric taut and even; and the accuracy and uniformity of size of the bights ,b, insure uniformity of width of the cut goods and eliminates waste of material.

The' whole arrangement is very simple and inexpensive, and well adapted to the requirements of Red Cross work and necessities. The device is in extensive use in many 5 Red Cross auxiliaries; and it is the applicants purpose to dedicate it to such use.

What I claim as m invention and desire to secure by Letters atent is,

In gauze folding apparatus of the charac- 10 ter designated, the combination of a supporting table formed with coincident scales on opposite sides thereof, a guide roller mounted upon and above said table, and transverse pin racks adjustably mounted upon said table, for the purpose described.
