BYRON O. LEAVITT, OF DENVER, COLORADO.

PLASTER-BANDAGE-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 770,912, date]. September 27, 1904.

Application filed April 23, 1904.

To all whom it may concern/.-

Be it known that I, BYRON O. LEAVITT, a citizen of the United States, and a resident of the city and county of Denver and State of Coldrado, have invented new and useful Improvements in Plaster-Bandage-Rolling Machines, of which the following is a specification.

My invention relates to machines for roll? ing plaster bandages for surgical use, and has for its obj ect to provide an improved machine of this class.

Heretofore, so far as I am aware, machines for rolling plaster-of-paris bandages have comprised a table over which was arranged a hopper open at its lower end for holding the plaster-of-paris to be spread onto the bandage strip and a rotatable arbor near one end of the table for drawing the bandage-strip over the table and under the hopper, so as to coat the strip with plaster and wind it into a roll the lower portion of the body of plaster with in the hopper would cake and clog against the side thereof, and as a result the plaster would not be distributed evenly upon the bandage-strip.

My invention has for its object to obviate the disadvantage above noted, as well as to otherwise improve the construction of machines for rolling plaster bandages.

My improved bandage-rolling machine comprises a frame, preferably in the form of a boX, a table fastened to said frame, an arbor journaled on said frame at one end of the table, means to rotate the arbor, a hopper supported by the frame above the table, whose outlet is preferably controlled by a valve or the like, and a scraper above and extending transversely of the table between the hopper and the arbor for leveling the plaster and controlling the amount thereof applied to the bandage. In the best form of my invention Serial No. 204,507. (No model.)

the scraper is a brush pivotally mounted on the frame, and means is provided for adjustably holding the brush in position, so that its position with relation to the table can be changed at will to control the amount of plaster applied to the bandage-strip.

Another feature of my invention in its best form is that the arbor is removable and made with a longitudinal slot open at one end to receive the end of the bandage-strip, so that when the arbor is turned the strip will be wound thereon, and a finished roll can be removed from the arbor with ease by sliding the roll off one end thereof, the inner end of the roll, which is in the slot, passing out of the open end of the latter.

i Other features of my invention are herein after pointed out.

In the accompanying drawings, Figure 1 is a plan view of my improved plaster-bandagerolling machine. Fig. 2 is a section on line 2 2 of Fig. 1. Fig' 3 is a detail hereinafter described. 7

Having reference to the drawings, A represents a table pivoted at one end on a rod a,

mounted at its ends in the sides of a boX shaped frame B. At its other end table A carries a rod a, mounted to slide endwise in lugs a provided upon the under side of table A. One side of the box-shaped frame B is made with a hole a adapted to receive one end of the rod (0' and by its engagement therewith to support the table A in a horizontal position. At its other end the rod a projects through a slot (0 in the opposite side of the box-shaped frame B, and upon the outside of the rod (0 is a handle-a, by means of which rod (0 may be moved by hand endwise to engage or disengage it from the hole a for the purpose hereinafter set forth.

Within the box-shaped frame B and at the bottom thereof is a movable tray O,into which falls whatever plaster drops from the bandagestrip D during the plastering operation. One end of strip D is carried upwardly over the table A and fastened to a rotatable arbor E, said end being inserted in one of a pair of slots 6, provided in the arbor E.

Arbor E is herein shown as made from a partially-split tube open at one end and provided with a handle a at its other end, the slots of the split beginning at the open end of the tube and terminating short of the other end. I

Mounted on the box-shaped frame B is a spindle e journaled at its outer end in a bracket 6 fast to frame B, and at its inner end in the frame B. This spindle e is provided with a flange a between bracket 6 and frame B, which holds said spindle against endwise movement, but permits it to be rotated by means of a crank a integral with.

the spindle. The inner end of spindle e is chambered, as shown in Fig. 3, to receive the slotted open end of the arbor E, the slots 6 of said arbor engaging a pin 6, mounted crosswise in spindle 6 Above table A is a hopper F, supported by lugs f upon the inside of the box-shaped frame B. Said hopper at its lower discharge end is provided with a slide or valve f, by operating which the plaster within the hopper F can be discharged onto that part of the strip D upon the table A in small quantities and as required.

Between hopper F and arbor E is arranged a scraper G, herein shown as a brush with resilient bristles and as pivotally mounted upon a rod g, supported at its ends by the box-shaped frame B. The brush G is made with a spring-arm g, having a laterally-projecting point at its outer end-adapted to engage the adjacent side of the box-shaped frame B and to thereby hold brush G at any desired angle with relation to table A. Thus by adjusting the bristles of brush Gr toward or from the table A the amount of plaster applied to the strip of the roll D can be regulated. The resilient bristles of brush G act to penetrate and'break up any lumps or cakes that tend to pass thereunder and to lay the plaster evenly upon the strip D as it is drawn under said brush by the rotation of arbor E.

The hopper F is removable from its supports f, and when the machine, is not in use it can be placed inside the box-shaped frame B, and the latter can be closed by a hinged panel &, forming part of a cover 6 of box B. In order to facilitate placing the end of strip D in position, one end of the box-shaped frame B is made with a hinged panel 6, by opening which access may be had to the interior of the box.

The tray C collects whatever plaster may fall from the strip D while it is being plastered, and its contents can be restored to hopper F by withdrawing tray C and emptying it into said hopper.

The purpose of having the table A pivotally supported and arranged to be tilted is to facilitate the admission of the end of the strip and so that after the plastering operation whatever plaster. remains thereon can be dumped into the tray with ease and convenience.

The cover 6 is made with an opening or window Z), in which is mounted a pane of glass or the like P, so that the interior of the box is visible from the outside. The panel 5, hinged to cover 6 is of such size that when it is opened and hopper F is placed in position the latter closes the opening formerly closed by the panel 6 and dust arising from disturbance of the plaster within the boxis confined thereinthat is, box B is closed when in use by the hopper F and when not in use by panel Z2.

Mounted in panel 6 so as to slide endwise therein is a rod 6 booked at its inner end to detachably engage a tongue provided on slide f. At its outer end rod 6 is formed with a handle, so that when its inner end is in engagement with slide f the latter can be operated through manipulation of rod 6 without opening the box.
