BANDAG-E-REEL Specification of Letters Patent.

Application filed April 12, 1915. Serial No. 20,878.

To all whom it may concern I 7 Be it known that I, JOSEPH KozEK, acitizen of the United States, residing at Avoca, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in'Bandage-Reels; and I do hereby declarethe following to be a full, clear, and exact descriptionofthe invention, such aswill enable others skilled in the art to which it appertains to make and use the same. I r 7 This invention relates to winding and reeling, and more especially to those devices intended for bandage rolling; and the Object of the same is to produce a reel onto which medicated or antiseptic fabrics such as gauze may be wound from the original rollS'or packages in which they are supplied, and from which a stretch of such fabric may be taken quickly. for surgical purposes.

It is well known that in hospitals for the treatment of emergency or war-time cases there are frequent hurried calls for stretches of antiseptic gauze and the like; and in drawing a stretch from a large roll such as supplied by the manufactory, considerable difliculty is experienced inhandling the roll as it revolves and in preventing it from accumulating foreign matter'which' is undesirable in the surgical dressing. Hence reels have been provided for rolling the strip of bandage material, and my present invention is designed to improve the: construction of such reels in the particulars which will be pointed out in the following specification and claim, and shown in the drawings wherein 'Figure 1 is a front elevation of this device complete, its right bearing being partly broken away and in section, and its shaft at the. right carrying one roll in full lines and at the left in dotted lines carrying another roll whose free end leads forward over the base. Fig. 2 is a vertical section on line 22 of Fig. 1. Fig. 3 is a rear elevation. Fig. 4 is an enlarged perspective detail showing the left hand shaftbearing as open; and Fig. 5 is a section on line'5-5 of Fig. 4. I

In the drawings the numeral 1 designates a base which may rest on or be clamped to a table or othersuitable support, and 2 and 3 are end pieces or uprights rising from the edges of said base at its rear and connected by the top piece 4. The base extends a little to the rear of said uprights and is provided in its upper face with a, number of 'holes 5 v and the rear edges of the uprights are connected by a bar 6 standing substantially above said holes and provided with notches 7 registering with them. Into any hole may be inserted the shank of a-hook 8 whose bill 9 overlies the bar and rests in one of said notches, and by providing several of these hooks a plurality of strips of gauze may be properly guided into the machine and to the rollers yet to be described. From this it will be gathered that the roll or package of gauze as it is received from the manufactory is to be located below or in rear of the machine and fed to the latter in any suitable way. In the rear edgesof said'uprights are open bearings 10 preferably inclined forward and downward from their months 11 as best seen in Fig. '2, and in these hearings are removably mounted the spindles 12 of the tension rollers. By preference I make the lowermost tension roller '13 relatively small, and the uppermost tension roller 14 relatively largeand heavy so that it will rest with some considerable friction upon the gauze. G which passes between these rollersas seen. Between the uprights at a point some little distanceabove the tension rollers is journaled a guide roller '15, and between the 11prights at a point forward of said tension rollers is journaled another guideroller 16. The gauze may be passed over the former and under the latter, oronly one guide roller may be used as'the case may demand and as suggested below. 1 I

By preference the uprights are cut away at their front edges as seen at 20 and provided with upwardly 21 in which are Jjournaledthe' spindles of the reel shaft 22, one end of which may be provided withv suitable operating means such as a crank handle 23, and the body of this shaft is by preference made angularbeing Shownas triangular in the drawings. To the front edge of each upright where it is cut away as at .20 is pivotedat 24 a block 25 Whose lower end'is made thick andrather heavy as at 26 audits eXtremi'tyis provided with a half-bearing27 adapted to complement the half-bearing 21. The lips or faces on the. upright and block 'in rear of these half-bearings are preferably made flat as seen at 28, whereas those forward of said bearings are inclined as seen at 29. The result isthat when the heavy lower end 26 of the block 25 swings into its normal upright position as seen in Fig. 1, the incline'd lips Patented Nov. 2, 1915.

facing half-bearings 7 form as it comes 29 come into contact with each other to hold the block upright just at a time when the half- bearings 21 and 27 closely engage the shaft spindle; and

in this position. The tension imparted to the gauze G tends to draw the roll on the shaft toward the rear, and upward if the gauze is led over the upper guide roller 15, and it is obvious that this tendency is resisted by the bearings described.

For opening the bearings to permit the removal of the shaft 22, the upper ends of the blocks arereduced in thickness as at 30, and a link 31 is provided which extends across the face of the machine and is pivotally connected tosaid reduced ends. By preference I carry one extremity 32 of said link to the rear as bestseen in Figs. 1 and 5, so as to form a tongue which stands normally outside the upright 3 at about the point 33, but which in Fig. 4: is shown as standing inside said upright so as to latch the blocks in position to hold the bearings open. In order to permit this tongue to be disengaged from the upright, its pivot 34 may be made in the shape of a bolt as seen in Fig. 5, its shank passing loosely through a hole 35 in the link 31 and having a spring 36 coiled between said link and the head 37 of the bolt. However, any suitable form of latch would answer, and it is not necessary that both blocks be latched because their upper ends are connected by the link. In use, the end of a strip of gauze in roll from the manufactory is fed into the rear of the machine at the point a, whence it passes under the bar 6 and between a pair of the guides 8, thence it is carried upward as at b and between the two tension rollers, and thence it 'is led as at 0 over the upper guide roller 15 (although it might be led under the lower guide" roller 16), and in the present instance it is carried down as at d under the shaft 22 so that when the crank handle 23 is manipulated a gauze roll R will be quickly formed. Obviously the gauzewill be wound tightly onto this roll because of the tension set up by thebar 6 and the guide roller, but especially by the tension rollers between which the strip in all cases will be passed. The weight of the upper and ratherheavy tension roller 14: will be sufficient to'press the strip with some considerable degree of friction onto the'lower tension roller 13. In this manner is the bandage material formed into a roll R on the reeling shaft, and under the ordinary practice the strip is cut off when the roll has reached its limit of size, the strip carried thence under the roll and led'over the base of the machine, and the surgeon or nurse grasps its free end and draws from this roll a stretch or stretches thereof as needed. But I have found that at this the weight of the lower ends of these blocks will tend to hold them single strip point anobj ection exists, because in drawing a stretch quickly from the roll R the latter is likely to be left spinning and the result is that the end protruding from the roll beyond the point where the stretch was cut off may become soiled, infected, or tangled in the machinery and perhaps dragged from the device by the clothing of the'attendants.

It will be observed from Fig. 1 that this machine is more than double the width of the ordinary strip of gauze, and this fact as well as the provision of two guide rollers produces a function and advantage which will now be explained. Let us assume that a roll it has been wound onto the shaft in the manner already described, and when this roll has reached the limit of its size the strip is cut off and the end thereof which leads'from the manufactorys roll is moved along the bar 6 to the other end of the latter, the guides 8 being appropriately adjusted. lhence the gauze strip is led upward as at 6 between the tension rollers as already described, and thence downward instead of upward, under the guide roller 16 and thence forward to the shaft 22 alongside the roll R already formed, but passed over the shaft instead of under it. The free end of the strip on the roll R is now led forward over base to within reach of the surgeon or nurse, and when the latter draws a stretch from this roll the shaft 22 is caused to rotate in a direction which is the reverse of the arrow shown in Fig. 2; and the result is that the strip last described iswound automatically onto the other end of the shaft. When its roll in turn reaches the limit of its size, the first roll will have been unwound; and at that time the operation is repeated except that the end of the manufactory roll is run through the machine as shown in full lines in Fig. 2, while the end of the second roll is then led rearward as at 6, around the guide roller 16, and thence forward as at f and over the base into position to be grasped by the surgeon or nurse. Therefore the provision of a plurality of guide rollers in the making of the entire machine of double widtln'affords means for causing the automatic'formation of one roll by the unwinding of stretches of gauze from the other roll from time to time. And it will be obvious that when both guide rollers 15 and 16 are in use there is tension applied both to the strip that is being reeled up and the stretch that is being drawn off. I do not wish to be limited to this use of my machine, however, as it is quite possible to reel but a of gauze onto the shaft, and unreel it therefrom in the well-known way. When the parts are made of double width, it is obviously possible to use the machine for extra wide bandages. But with this use of my machine it is rarely necessary to open the the shaft'bearings as seen in Fig; I for the removal of either roll, althoughv this POSSI. bility still remains, Nor do I wish to be limited to the use of a latch for holding the movable blocks in their upright or inclined position, as it may be that the Weighting of their lower ends as at 26 or the inclining of the lips 29 will be quite suflicient.

What I claim is:

In a bandage reel, the combination with a pair of uprights spaced more than double the Width of the fabric to be reeled and hav-v ing slotted bearings in their rear edges and open hearings in their front edges, a" reel shaft journaled in the'last-named bearings, and means for holding it- .removably in place; of a tension roller Whose spindles are journaled in said rear bearings, a second and heavy tension roller Whose spindles are Witnesses:

' also journaled in these bearings abovethose just mentioned, and two independent guide I rollers journaled in the uprights and standing at differentpointsbetween their front last named strip the first named be automatically reeled. 1 a I In testimony whereof I aflix my signa ture in presence of tWo witnesses.
