Application filed October 7, 1919. Serial No. 329,084.

To (all 10/20771- '1' i may concern.

lie it known. that I, MAX IVILLNER, a citizen of the United States, and a resident of the city of New York, borough-of Manhattan. in the county and State of New York,

' have invented a new and useful Gauze-Fold ing Machine, of which the following is a full. clear. and exact description.

This invention relates to devices for coiling strips of cloth and has for an object the provision of an improved construction wherein gauze or other narrow strips of cloth may have the edges folded and then folded along a central line in a continuous operation.

Another object of the invention is to provide an improved construction which will take a comparatively short roll of gauze and fold the edges and then fold the strip in the center after which the folded cloth is wound into a compact disk-shaped structure.

still further object, more specifically, 18 to provide a folding device for bandage gauze now in common use in hospitals wherein the parts will fold the gauze and then wrap the same into a disk, folding same so that the raw edges will be turned in.

In the accompanying drawings:

Figure 1 is a perspective view of a folding machine disclosing an embodiment of the .invention.

In the manufacture and forming of dress ings for use in hospitals and elsewhere for the treatment of wounds or for use during operations it has been customary to provide gauze bandages for binding purposes and also folded gauze to place in the wounds. Heretofore it has been customary to cut the gauze cloth into narrow strips and wind the same so that there will be some rolls of gauze of comparatively narrow width. In using these strips of gauze it is necessary to turn 1n the rough or raw edges and then fold the strip centrally so as to secure the benefit of the gauze while not permitting any loose threads to project. The foldingof the strips of gauze in this manner -is a tedious operation and requires considerable amount of time in large hospitals where a large amount of gauze of this character is used. In the present invention means have been provided which will receive a roll of gauze and will quickly fold in the edges and then fold the strip centrally after which the folded strip 18 wound in a spiral or disk-shaped structure. Referring to the accompanying drawlngs by numerals 1 indicates a base or support, which in the present instance has been made hollow so as to receive a drawer 2, which drawer may carry one or more extra rolls of gauze or-othcr matter as preferred. On the upper face of the base '1 is arranged a plate 3 preferably of metal, which is provided with bent-up ears 4 at one end be tween which the roll 5 of gauze is placed preparatory to the folding thereof. At the opposite end of the plate 3 guiding ears 6 and T are provided for the folded gauze to guide the same into a winding apparatus 8 hereinafter fully described. Adjacent the ears 6 and 7 a turned down projection 9 is provided for receiving a screw or other fastening, while at convenient points. along the plate 3 other fastening means are provided. The ears' accommodate a pintle 10 around which is wrapped part of a hood 11, which hood is thereby pi votally mounted in place. The front edge 12 of the hood 11 is designed to rest against the full width of the strip 13 from the roll 5. The edge structure 12 merges into a bent-up neck 1a which in turn merges into a spreader 15, shown heart-shaped, though some other shape could be used without departing from the spirit of the invention. The spreader 15 extends to near the preliminary folding members 16 which are rigidly secured by' screws or otherwise to the plate 3. Spaced a proper distance from the preliminary folding members 16 are a second pair of folding members 17, While a third or last set of folding members 18 are arranged a short distancev from the ears 6 and 7. These various folding members are spaced ap proximately the same distance apart, but

it is evident that they may be spacedfarther apart or closer together as desired. The preliminary folding means, as shown in F ig. 4:, are each provided with an inwardly extending edge 19 merging into a body 20 "off the folding member, which body is pro vided with a flared front 21 so as to receive the cloth easily. As the cloth passes into the member 16 the edges are folded over so that a section along each edge is parallel with the plate 3, said sections leaving the member 16 in this position. The second set of folding members 17 are provided with flaring ends 22 whiclnmerge into almost vertical portions 23 as indicated in Fig. 5. Itwill thus be seen that the first folding members turn over the edges while the second bend the strip substantially on a central line, which bending action is completed by the members 18 which are parallel and which extend at right angles to plate 3 except the slight entering bulged portion 24: in each member. As the strip leaves the members. 18 it is extending at right angles to the way it is positioned beneath the spreader 15, but is turned as it passes between the ears 6 and 7. I

Connected with the end 25 of base. 1 is a winding device 8 into which the folded strip passes. At first the end of the folded strip is passed into the notch 26 as shown "in Fig. 7 and as the crank 27 is rotated the folded strip will be wound into a substan- 1 tially disk-shaped structure and between the side plates 28 and 29. lVhen the complete roll 5 has been folded and wound on the stub shaft 30, said stub shaft is removed by a direct pull and the wound folded gauze is forced fromthe winding member 8 by an ejector 31. This ejector is merely a bar pivotally mounted at 32 with the lower end substantially arc-shaped whereby when the upper end 33 is depressed it will press against the wound gauze and force the same r from between the plates28 and 29.

bandagetation of the crank 27 the spreader 15 holds the strip in proper place andguides the same so that the edges of the strip will properly be engaged by members 16. for turning them over to the position shown in Fig. l. It will, of course, be evident that the operator must watch the operation so that in case the strip should move slightly to one side or the other a proper manual ad justment may be made so as to cause a continuous proper folding action.

lVhat I claim is:

1. A bandage strip folding machine comprising a holder for a roll of bandage material, a plurality of folding members arrangedin a line through which the strip is adapted to pass, and a spreader for holding the strip in proper place as it enters the first folding member.

2. A machine for turning in the edgcs and folding bandages con'iprising a base plate having a pair of turned-up ears adjacent'each end, one of said pair of ears acting in the combined capacity of guiding and folding means while the other acts as holding means for a roll of bandage cloth, a plurality of spaced folding member arranged on said base between the ends of the base, the folding member nearest the roll producing a preliminary fold while the remaining members act successively for completing the. turning in of the edges and then folding substantially on a. central line.

A machine for folding a strip of gauze longitudinally comprising a holding memher for a roll of gauze, a tension member engaging the gauze adjacent the roll, a spreader adjacent the tension member, a pair of folding members for folding the edges inwardly, a pair of folding members for folding the strip centrally, and means for causing the folded strip to be permanently creased as it leaves the machine.

4. A bandage strip folding machine comprising a supporting base having a flat upper surface a plate extending longitudinally "of said flat upper surface and connected therewith, said plate havinga pair of upturned ears adjacent each end, one of sa d ears be ng larger than the ther, a

pivotally mounted holder for a roll: of bandage material arranged so that the large upstanding ears will act'as end members therefor, a spreader for the material as it leaves said holder, a plurality of folding means between said spreader and the smaller set of cars, and a winding member adjacent said smaller set of ears for Winding the folded MAX WILLNER.
