CARRIER AND DISPENSER FOR ST RIP MA'ZRERIAL IN ROLL FORM Filed Dec. '15, 1942 I 1 run) [on Vhvazwr NEPTLWE Patented July 20, 1943 OFFICE CARRIERAND DISPENSER FOR STRIP MATERIAL IN ROLL FORM Vincent Neptune, Brookline, Mass. Application December 15, 1942,-Serial No. 469,104 3 Claims. (0,1. 24.2-55.2)

This invention is directed 'to a carrier and dispenser for strip material in roll form, the carrier being particularly constructed to permit convenient application and removal of the roll as i such, and to provide for dispensing the strip as I such, in serial form, confines against possibility of twisting or distortion during delivery, with the freedom of delivery variably and selectively restricted at will to permit a tightened winding of the dispenser strip without direct physical contact with the strip.

In certain uses of the carriers of the contemplated type, to which uses the present invention is in no wise restricted, as for example, in winding strip bandage in medical use, or in applying insulating strip to wire or electrical connections, it is of prime importance that the strip be delivered fiat or untwisted to the point of application, and further, that the free movement of the I- strip be restricted to a selected degree to insure and dispenser constructed to permit convenient application and removal of the roll as an entirety, with the device also providing for dispensing the roll serially while avoiding direct handling of the strip, the dispensing means insuring that the strip be delivered in normal fiat and untwisted condition; there being provided a con- Utrol to insure that the resistance of the movement of the roll during dispensing of the strip may be governed at will to permit as relatively tight an application of the strip as may be desired.

The invention is illustrated in the accompanying drawing, in which:

Figure. 1 is a view in elevation of the carrier and dispenser with a strip roll in dispensing position therein.

Figure 2 is a plan of the same.

Figure 3is a section on the line 33 of Figure 1 t Figure 4 is a perspective view of the carrier and dispenser, partly broken away.

The improved carrier and dispenser includes a frame of U-iorm in plan, of greater length than width, with side bars I and an end bar 2. The sectional dimensions of the frame bars are preferably small, but obviously the showing indicates no restriction in this particular.

The side bars I, at their approximate midlengths, are strengthened, preferably by slight enlargement, to provide for the reception of apin 4, headed at one end, and threaded in its extension at the other end to receive a nut for securing the pin removably in and transverse the frame. A sleeve 5, forming the center of the roll, indicated at 'l, is freely rotatable on the pin 4, when the parts are assembled, whereby the roll is rotatably supported in the frame. The side bars I, immediately adjacent the end bar 2, are formed to receive a transverse guide roller 6, whichwhile preferably rotatable may without loss of function be fixed in the side bars. The roller 6 provides a guide for the passage of the roll strip during dispensing, and is preferably located close to and in parallelism with the end bar 2. The opposite ends of the side bars, that is, their free ends, are formed to receive what may be termed the dispensing control. This includes a rod 3, passing more or less freely through one side bar I and threaded into a suitably reinforced portion of the other side bar I, It is apparent that the bar 3 may be adjusted for causing the side bars I of the frame to create roll resistance, as will be later explained.

The roll 1, formed of course of appropriate strip material, is either supplied with the sleeve 5 or wound on a similar base. The bar 3 is withdrawn and the roll passed between the side bars until the sleeve is in position to permit the entry of the pin 4, which when secured supports the roll for rotation within the frame. The end of the strip is passed over the guide roller 6 and beneath the end frame bar 2 and outwardly therefrom for dispensing.

A characteristic feature of the improvement is that the frame is fashioned to accommodate the width of the roll While normally permitting freev rotation of such roll. In this relation, the strip passing over the guide roller 6 is maintained at full width and in flat condition to insure that such strip beyond the frame will be similarly delivered to the object of application. If and when it may be necessary to apply the strip to the object with some degree of tightness, the rod 3 is operated to draw the side bars I of the frame toward each other. This, which of course is selective in degree, will cause the side bars beyond the pivotal roll support to exert a binding action on the sides of the strip roll I, with the effect to permit the user to apply the strip with greater force. Of course, the movement of the rod 3 in any such adjustment will be slight.

The strip is applied or dispensed by handling the roll by means of the fram entirely, the hands not contacting with the strip. In this application, the carrier and roll is carried around the object being wrapped, and with the play of the roll restricted by operation of the rod 3, as explained, this resistance of free roll movement permits application of the strip with desired tightness and pressure.

The hands do not contact with the roll or strip in applying the strip, and thus contamination of the strip is largely prevented, a desirable feature in medical bandaging, The frame for the roll is of course to -be of an appropriate size to receive and utilize any width strip, and obviously such frame may be cheaply constructed. Furthermore, metal is not required, as owing to the lack of strain and stress on the frame, it may be made of plastics, Celluloid or the like.

It will of course be understood that the improvement herein described is designed for use in connection with any and all types of ribbons in roll form, and is in no Wise limited in use of construction, otherwise than as defined in the appended claims.

What is claimed as new is:

1. A roll strip carrier and dispenser, including a U-shaped frame having side bars and a closed dispensing end, means carried by the side bars for rotatably supporting a roll of strip material,

a guide member arranged adjacent and parallel to the closed end of the frame to provide for delivery of the strip over the guide member and beneath the closed end of the frame to maintain the strip in flat condition for delivery, and means at the ends of the side bars wholly beyond the roll of material to compel relative movement of the side bars throughout the full side dimensions of the roll to thereby tension each and every strip layer on the roll during dispensing to control the character of the roll application.

2. A roll strip carrier and dispenser including a U-shaped frame having side bars in substantially parallel relation connected at one end by an integral cross bar at right angles to both side bars, roll supporting means carried by the side bars at substantially their midlengths, sidebar tensioning means connecting the side bars at the ends remote from the cross bar, and a guide member connecting the side bars in parallelism with and immediately adjacent the cross bar, the guide providing a means for permitting the strip to be drawn over the edge of the cross bar, the right-angles relation of the cross bar to the side bars compelling the strip in passing over its edge to be maintained in a flat condition.

A construction as defined in claim 1, wherein the means for compelling relative movement of the side bars includes a threaded bar passing freely through one side bar and having threaded cooperation with the other side bar, said threaded bar being wholly removable to permit application and removal of a roll strip.
