SPOOL HOLDER Filed May 5, 1928 2 Sheets-Sheet 2 /////////VI y,

five/22921 @22 7 Patented Mar. 27, 1934 UNITED STATES 3 Claims.

My invention relates to spool holders and particularly to spool holders used in stores upon which to wind wrapping tape or ribbon.

Inthe ordinary spool holders now on the market, in unwinding the tape from the holder the spool will continue in revolution, unwinding the tape more than is necessary and occasioning inconvenience and difficulty. Furthermore, in severing the tape from the holder in the devices now on the market it is necessary to hold the tape on either side of the cutting means.

My invention provides a spool holder frictionally engaged with its mounting so that when sufficient tape has been unwound the holder will not continue in revolution but will stop, sufficient resistance in the mounting being provided so that the tape is held at a tension by the frictional resistance provided in the holder while being cut on the knife provided for that purpose.

Other objects and advantages of my invention will appear from a consideration of the following detailed description, in connection with the accompanying drawings, in which- Figure 1 is a top plan view of the device embodying my invention;

aluminum or the like, having substantial weight, although it is to be understood that the base may be drawn or formed of a sheet metal. The cas"- ing is provided with rubber feet, in order'to prevent the marring of a finished surface, the weight T of the material of the casting providing the stabilizing means for the apparatus However, apertures are provided in the base through which screw members or other securing means may be extended to fix the base to a counter or the like, apertures being particularly desirable when the base is formed of sheet metal.

A pair of end supports 21 and 21' are provided on each side of the casting and extend vertically therefrom, the supports comprising generally a pair of leg members to be fixedly secured to the base and a bearing member at the upper end thereof to receive supporting means for the spool. Referring now more particularly to Figs. 6 and '7 of the drawings, the bearing or housing 38 is provided with a central longitudinally extending aperture for receiving a stud shaft 3'7 preferably formed integrally with a plate member 36, the shaft'having a reduced circumferential portion 42 within the aperture of the bearing into which a spring pressed plunger 41 is engaged. The plunger 41 is disposed in a vertically extending recess of an extension of the housing 38 and is pressed upwardly by the coil spring 40 into engagement with the reduced portion 42. Any desired amount of tension may be had on the plunger 41 as by means of tightening or loosening a thumb screw 28 which threadedly engages a continuation of the aperture into which the plunger 41 is fitted. A plurality of pins or lugs 35 are disposed on the face side of the plate 36, the pins being equidistantly spaced from the axis of the plate and from each other peripherally. Thus the rotation of the plate 36 is restrained by the spring pressed plunger 41 to a desired degree. I

Referring now more particularly to Figs. 8 and 9 of the drawings the other end support is shown and comprises a pintle 26 disposed in a longitudinally extending aperture in the hearing or housing 44, the pintle being recessed a substan tial distance on the innerend thereof to accommodate one end of the coil spring, the other end of the spring bearing against the end wall of the aperture. The outer end of the pintle 26 has a reduced extension thereon for a purpose which will hereinafter be more fully described. The longitudinal movement of the pintle is determined by a bayonet slot 27 through which a handle 25 extends. The pintle 26 may be retracted from its extended position as shown in Fig. 9 by moving the handle to the left and thereafter moving the same downwardly in the vertically extending portion of the slot 27, this slot retaining the pintle in its retracted position.

The spool 22 comprises a cylindrical shell member formed preferably of sheet metal or of metal tubing. A spool head having a central aperture substantially smaller in diameter than the outer diameter of the cylindrical shell is disposed against a shoulder formed on the cylindrical shell and has a flange on the outer side thereof, to hold the head in a fixed position against the shoulder. The outer periphery of the head is beaded over to strengthen the head. A cupshaped sheet metal member is disposed at each end of the cylindrical shell, the open end of the cup-shaped members being internal of the cylindrical shell and being of a diameter to snugly engage the inner diameter of the shell. A peripheral groove 4'7 is provided near the outer end of the cup-shaped member to receive and to engage the fianged over portion of the. spool head.

The closed end of the cup-shaped member, that is, the outer end thereof, is provided with an axial opening 46 and a plurality of auxiliary apertures 45 disposed about the axial opening 46. The apertures 45 are preferably stamped from the material forming an annular groove 47, which is depressed from the surface of the member. The apertures 45 are preferably equidistantly spaced from the axis of the cup-shaped member and equidistantly spaced peripherally, corresponding thereby to the lugs provided on the face plate 36. A flange is provided from the material surrounding the opening 46 whereby a bearing portion is provided to seat on the reduced extension of the pintle 26, the shoulder formed at the junction of the reduced extension and the pintle 26 abutting against the face side of the cup-shaped member adjacent the opening 46.

When it is desired to position the spool within the apparatus for dispensing the tape, the pintle 26 is retracted and. either end of the spool is presented to the supporting member or plate 36. The groove 4'? in the spool greatly facilitates the registration of the apertures and the lugs 35, the lugs dropping into the annular recessed portion, whereafter the spool is rotated slightly until the lugs drop into the apertures. The handle 25 is raised out of the vertically extending portion of the slot 27, whereafter the coil spring associated with the pintle 26 urges the latter into engagement with the other end of the spool, that is, the reduced extension engaging the opening 46. The spool in its association with the present apparatus is held against rotation, unless manually forced, by the action of the spring pressed plunger 41, whereafter it is not necessary, while severing the binding medium contained on the spool, to manually hold the same on each side I of the cutting device illustrated in the drawings and which will now be described.

A supporting member 23 is fixedly mounted on the base 20 as by means of screws extending through the supporting member and the base. In the present illustration the supporting member 23' is curved, the curve conforming to the outer periphery of the spool 22 and being spaced therefrom a substantial distance. The upper end of the supporting member is enlarged to form a head portion 23, the head portion being formed preferably integrally with the supporting member 23. The enlarged head 23 has a recessed por tion of a size and shape to accommodate a common type of a razor blade 29 or other sharpedged blade, the blade being disposed substantially centrally of the width of the head. A pair of spaced pin members 34 and 34' are preferably formed integrally with the head to extend through apertures 33 and 33, respectively, formed in the blade. It is, of course, to be understood that these projecting pin members 34 and 34 may be separately attached to the head portion, or arranged in various manners to accommodate or to fix in position, razor blades or other cutting devices of various types. A retaining plate 31, having a pair of apertures in alignment with the pins 34 and 34 and the apertures 33 and 33, is disposed against the blade 29 to hold the same in a fixed position in the recessed portion or depressed area. A screw 32 is inserted through an aperture in the head and extends through an aperture in the blade in axial alignment with the aperture of the head and thence into a threaded aperture of the retaining plate 31 to draw the latter against the blade.

The retaining plate 31 has a cut-away portion, which extends along the cutting edge of the blade in a converging direction towards the upper end thereof from a point near the lower end. A lip at the lower end of the retaining portion projects a sufficient distance to bear against the lower end of the blade adjacent the cut-away portion, in order that, when the tape is severed against the cutting edge of the blade, a proper support is obtained for the blade adjacent the point at which the greatest force is exerted.

The head 23 is provided with a reentrant opening to guide the tape or other binding means to the blade to be severed. It will be noted in the drawings that the reentrant opening is bounded by an edge a, which is substantially parallel with the edge of the blade to direct the binding tape to the opposite edge b of the reentrant opening, which latter edge directs the tape forwardly and downwardly to the cutting edge. The edge a is abruptly terminated by another edge portion 0, which extends substantially at right the cutter head 23 with one hand to be directed against the blade and severed. The positioning of the head 23 is immaterial to the proper functioning thereof and it will be noted that a desired position may be had by disposing the head on the front side of the apparatus adjacent the plate 24, which latter plate rests on the tape and causes the end thereof to be held against displacement and in position to be grasped by the hand of the user. The reentrant opening is so arranged that but a careless manipulation of the tape is required and but a single hand need be employed in the operation of this particular device since the spool is under tension.

While I have shown and described but one embodiment of my invention, it is obvious that many modifications therein may occur to those skilled in the art, and, I desire, therefore, that my invention be limited only by the scope of the appended claims and by the prior art.
