Patented Oct. 15, 1929 PATENT OFFICE MALCOLM. RAYMOND, or HOMER CITY, PENNSYLVANIA ADHESIVE ELASTER-DISPEN SING DEVICE Application filed February 21, 1927. Serial No. 169,805.

An object-of this invention is to provide an adhesive plaster dispensing device of novel, simple and efficient construction whereby gai-i'ze covered adhesive plaster in rolls may be supported and -ma-nipu lated in a 'manner to permit pieces of the plaster to ibe easily and quickly removed from the gauze, whereby the plaster may be kept clean and sterile and read-y for instant use, whereby the hand-l ing ofthe plaster and the protecting gauze is reduced to a minim-um in hospitals, dressing stations and other places Where large quantities of plaster are used, and whereby left over ends of pieces of plaster removed from the gauze may "be easily and quickly returned thereto and subsequently removed therefrom for use.

,A further object of the invention is to provide a novel and advantageous method of dispensing gauze covered adhesive plaster from rol lsthereof with the aid of a suitable mechanical device. I I

With 'the foregoing and related objects in view the -invent-ion-consists of the elements -and the combinations of them and of the method of dispensing the p'laster' hereinafter described and claimed.

In the accompanying drawings illustrating the invention, I I

Figure 1 is a front view, partly broken away, of, a dispensing device, embodying my invention, showing the adhesive plaster and its gauze thereon.

Figure 2 is a {side view thereof applied to a supporting wall, the wall being shown in section. Figure ,3 is a transverse section through the device, on line 3-3 0 f Fig.1.

Figure 4 is a sectional detail, showing the receiving shaft and adjuncts.

Figure '5 is a transverse section through the receiving shaft showing thejgauze attached to one of the spurs or hooks of the shaft, and showing a piece of the adhesive plaster partially stripped from the gauze.

{Referring to the drawings, 2 designates a frame which may be of any suitable shape and size for its intended purpose. As herein illustrated this frame 2 comprises vertical-ly-arranged side bars '4 and 5 and upper is provided to receive and have wound upon and lower brackets 6 and 7 respectively, which are secured to the bars iand 5 and which hold them in spaced parallel relation. The brackets 6 and 7 extend back from the bars 4: and 5 and they are provided with 5 holes 8 for the reception of suitable screws 9 by means of which the frame may be secured to a wall of a room in a hospital or other place where it is desired .to use the device, such wall being shown in 1880131011,"? at 10, in Fig. 2 of the drawings.

Supported by the upper-and :lower end portions of the side barsi and '5 of the frame 2 and extending transversely between them are two horizontally-arranged, parallel shaftsll and 12, respectively. The upper shaft 11 is provided .to receive and rotatably support a roll of gauze covered or protected adhesive plaster 13, and the lower shaft 12 it the gauze 1 1 from'the :roll of gauze and plaster 13, as will he hereinafter described.

The upper or delivery shaft 11 has-a collar '15 adjustably and removably secured to one end portion thereof by means of a set J screw '16; and the other end portion of the shaft 11 has a collar '17 suitably secured thereto. The respective .ends of the shaft 11 project outwardly from the collars 15 and 17 and are seated in downwardly extending slots or sockets '18 in the side bars 4 and 5. The slots 18 haveopen upper ends to permit the ends of the shaft 11 :to ;be readily inserted into .and removed from the same. The fixed collar 17 has a projection or extension 19 I thereon which fits against the side Walls of the slot 18 in the bar -'5 to prevent the shaft 11 from turning.

' Slidable .on'the shaft 11 adjacent to the collar 17 is a tloosecollar 20, and encirclin y the shaft 11, between the ifixed collar 17 and looselcollar 20 is a spring 21 which {tends to force the loose collar 20 toward the fixed collar 15 previously referred to.

presses the opposite end ofthe roll 13 against the fixed collar 15. The pressure of the spring 21 is such as to prevent the roll 13 from turning freely on the shaft 11 and to provide the desired tension for the adhesive plaster 22 and the gauze 14 by which it is carried when they are drawn from the roll 13.

The lower or receiving shaft 12 is mounted to turn in suitable bearings in the lower end portions of the side bars 4 and 5 of the frame 2. One end portion of the shaft 12 extends outwardly from the side bar 5 and carries a crank 23 provided with a handle 24 by means of which the shaft 12 may be manually turned. The other end portion of the shaft 12 extends outwardly from the side bar 4 and has a collar 25 fixed thereon. A spring 26 encircling the shaft 12 is interposed between the bar 4 and collar 25 and tends to move the shaft 12 longitudinally to move the crank 23 toward the side bar 5. The shaft 12 has a collar 27 fixed thereon adjacent to and inwardly of the side bar 4; and arranged between the collar 27 and the bar 4 is a plate or block 28 having a facing 29 of leather or other suitable friction material adapted to bear against the collar 27. The shaft 12 penetrates the plate 28 and its facing 29, and one prevent the plate 28 from turning with the shaft 12 and to permit the plate to be moved rounded end seated in a socket in the plate 28. The screw 31' may be adjusted by turning it to force the plate 28 and its leather facing 29 against the collar 27 and against the yielding action of the spring 26 until the V necessary friction is produced for the desired retardation of the turning of the shaft 12.

The shaft 12 is provided with two or more pointed spurs or hooks 32 for engagement with the free end portion of the gauze 14,

whereby the gauze may be wound upon the shaft and thereby drawn from the roll 13 when the shaft 12 is turned by hand.

In using the device the shaft 11 is removed from the frame 2 and the collar 15 is removed from the shaft. The roll 13 0f gauze protected adhesive plaster is then placed upon the shaft lland the collar 15 is returned to the shaft and secured in place thereon by means of the screw 16 after the collars 15 and 20 and the interposed roll 13 have beenforced by hand against the action of the spring 21 until the collars 15 and 20 act withsuitable pressure against the ends of the roll. The shaft 11 is then returned to the frame 2 with I the parts of the device in the position shown in the drawings.

the gauze 14 of the roll 13 is then drawn down- The free end portion of to the shaft 12 and engaged with the hooks or spurs 32 thereon. The shaft 12is then permits the adhesive plaster 22 to be removed from the gauze 14, without turning the roll 13 or shaft '12, by stripping the plaster 22 from the gauze 13 upwardly from the lower end of the plaster. Strips of plaster of different widths are stripped from the gauze by tearing the plaster longitudinally as'it' is stripped upwardly after the lineof tearis first started by a cut made by a pair of scissors or other cutting device, and, after a desired piece of plaster has been stripped upwardly from the gauze the plaster is cut transversely from the main bodythereof by a pair of'scissors or other cu'ttingtool and is ready for use. If the entire pieceof plaster.

stripped from the gauze is not used, the surplus thereof may be plastered back upon the end portion of the plate 28 is loosely connected to the bar 4 by a screw 30 in a manner to gauze and thereby kept clean and in'proper condition for use at another time.

After all or nearly all of the plaster carried by that part of the gauze extending between the roll 13 and the shaft 12 has been stripped from the gauze, the crank 23 is operated to turn the shaft 12 to wind the gauze 14 upon the shaft and thereby.

unwind the gauze 14 and plaster 22 carried thereby from the roll 13 until adesired fresh area of plaster" is presented upon that portion of thegauze which extendsbetween the roll 13 and the shaft 12. The plaster of this fresh area is then stripped from the gauze as previously explained and the plaster is usedas needed, and so on until theentire roll 13 of plaster and gauzehas been used; 1' a 1 After the entire roll of-plaster has been used, the gauze 14 may be removed from the shaft 12 by turningit oppositely to the direction indicated by the arrow-in Fig. 2. During the unwinding of the gauze from the,

shaft 12the friction of the leather facing 29 against the collar 27' may be relieved by loosening the screw-31 to permit the shaft 12 to. turn freely. q r I claim as my-inventionz I V In an adhesive plaster dispensing device andin combination, a frame, a delivery shaft removably mounted on the frame, a collar removably secured on the shaft, a collar slidable on the shaft toward and from the first named collar, said shaftand said collars being removable as a unit from the frame, yield able means carried by the shaft and con stucted to act yieldingly against the slidable collar when it is moved away fromthe first named collar, means to prevent the shaft from turning, a receiving shaft journaleol on the frame in spaced relation to the delivery shaft, and means operable to turn the receiving shaft.

In testimony whereof I aflix my signature.

MALCOLM RAYMOND.
