BANDAGE APPARATUS Filed April 19, 1940 IINVENTOR. WALTER W. SIMPSON ATTORNEY Patented May 18, 1943 UNITED STATES PATENT OFFICE BANDAGE APPARATUS Walter W. Simpson, SanAntonio, Tex. Application April 19, 1940, Serial No. 330,610
(Cl. 91 s2) 5 Claims.
This invention relates to the art of fabric coating, and particularly to the manufacture of plaster of Paris bandage rolls. 1
A common'method of preparing such bandages is to pass a strip of bandage materia1 beneath a superimposed bed of plaster of Paris or similar substance whereby the strip becomes coated therewith, and to wind the coated strip on a roll former from which it is unwound when placed in use. Although practical, the method does not assure uniform loading of the bandage due to the difficulty in procuring proper retention of the coating substance on the bandage fabric.
An object of the invention is to provide an apparatus by which bandagefabric may be uniformly loaded with a coating substance of plaster of Paris or like material whereof a substantial portion is worked into'the interstices and strands of the fabric by positive means inherent in the apparatus.
Another object is to provide an apparatus for forming rolled bandages of fabric coated with plaster of Paris or similar material which is mechanically worked into the body of the fabric.
Other objects will be readily apparent to those skilled in the art. 7
In the accompanying drawing;
Figure 1 is a top plan view of the apparatus. Figure 2 is a vertical sectional view taken 1ongitudinally through the apparatus.
Figure 3 is a fragmentary elevation, partlyin section, illustrating a detail of the roll former and its mounting.
Figure 4 is an enlarged fragmentary section of the coating material incorporating means.
Figure 5 is a perspective view of the roll holder.
Figure 6 is a section taken on the line 6-6 of Figure 3.
The apparatus comprises a casing in the form of an elongated trough open at each end and having an imperforate, flat bottom I and imperforate, parallel side walls 8. At one end of the trough the side walls provide bearings for a transverse spindle 9 which carries a supply roll I ll of crinoline or other suitable bandage fabric that is trained under the bottom of a vertically slidable gate H which is located in proximity to the roll and forwardly thereof.
At the other end of the trough, for purposes of description designated as the forward end, the side walls provide bearings for a second transverse spindle l2 which extends through one side wall and carries on its end an operating crank I3 by which the spindle may be rotated. The spindle l2, which constitutes the winding element Iii) of the apparatus, is adapted to receive thereover a core I4 on which the prepared bandage is wound as a roll IS. The spindles are movable axially into and from their bearings in the side walls for assembly purposes, and the rolls are slidable axially over their spindles for insertion or removal relative to the apparatus. One end of the winding core I4 is provided with diametrically opposed notches or slots l6 which take over the radially projecting ends of a securing pin ll that is fixed to the spindle l2, whereby the core is keyed to the spindle for rotation therewith. Diametrically opposed slots I8 in the adjacent side wall 8, see Figures 3 and 6, provide clearance for the ends of the pin l1 whenthe spindle is moved axially through its bearing. The spindle end is formed with an annular bearing groove H! which receives the edge of the bearing aperture 2D and prevents axial shifting of the spindle until'it is raised sufliciently to clear the engagement. A similar bearing assembly is provided at the other end of the spindle I2 and at both ends of the spindle 9.
The gate I I is adjustable vertically in its guides 2| and extends transversely between the side walls 8 to form a rear wall for the hopper section 22 which contains a supply of plaster of Paris or other suitable materia1 as a relatively deep bed 23. The forward wall of the hopper consists of a rearwardly inclined spreader gate 24 that also is vertically adjustable between the walls 8 to determine the thickness of the applied coating.
An inverted V-shaped member 25 extends transversely between the side walls and is fixed on the trough bottom in spaced relation from the bottom of the gate 24 and forwardly thereof, and at substantially the same spacing but forwardly of the member 25 there is disposed a tamping member 26 having a forwardly directed, relatively wide base flange 21 which overlies and parallels the trough bottom. The tamping member with its base flange extends transversely between the side walls and operates to secure the same results as are obtainable in the bandage by hand rubbing.
In assembling the apparatus the fabric from the supply roll I0 is trained forwardly beneath the gates H and 24, over the ridge of the lift member 25, downwardly again beneath the tamper flange 21, and is secured on and to the core [4, as by anchoring in a longitudinal slit 28 or by any suitable securing means. The bed of coating material 23 is then supplied to the hopper 22, and the apparatus is in readiness for operation.
Upon rotation of the winding spindle [2 the strip of bandage fabric is drawn through the bed of coating material and receives a load which is evenly distributed thereon by the spreader 24. A quantity of the coating material rapidly collects at both sides of the lift member 25 beneath the fabric web and on top of the web immediately before it passes beneath the tamper, as well shown in ,Figure 4. The bottom edge of the spreader 24 forces the coating material into the interstices and strands of the fabric from its upper side, and the member 25 functions to force the material into the body of the fabric from its under side, so that the fabric web is thoroughly incorporated with the coating substance. As the web passes beneath the tamper it is subjected to further pressure application of the coating in a manner similar to hand rubbing.
' The loaded fabric passes from the tamper to the winding spindle l2 and is wound thereon as a prepared bandage roll i5.
ages of any widths that may be accommodated between the side walls of the casing. While the present disclosure relates particularly to the use A of plaster-of Paris as the coating material, it is to be understood that any suitable powdered material may be used, and that the fabric to be coated may be other than bandage fabric.
In order to salvage excess coating material a collectingplate 29 is mounted on the casing bot- ,tom beneath the roll i5 and extends beneath the tamper into abutting engagement with the lift member 25. The plate is slidable longitudinally on the casing bottom through the open forward i end, and is removable for the purpose of returning its collected material to the hopper 22.
I claim:
