2 Claims. (Cl. 242-105) The present invention relates to a reel primarily devised for sup-porting band coils that are utilized for packing and crating. One of the main objects of the invention is to provide a reel of the character described which includes adjustable features for accommodating band coils of various widths, interchangeability of the coils being easily and readily effected.
Another object of the present invention is to provide a reel having suitable brake mechanism that will automatically prevent unraveling of the band of the coil whenever the coil over-spins.
In addition to the last related object, the present reel also provides the braking feature noted which is operative by its novel arrangement to stop unraveling of bands regardless of the widths of bands whichare placed in the band reel.
Among the other features to be noted is the fact that the reelv devised is primarily portable, but may also be secured'in place adjacent a packing table or the like.
Other objects and advantages shall hereinafter appear in the following `detailed description of a preferred form of my invention as directed to the accompanying drawings.
In the drawings:
Fig. l is a side elevational view of the band reel.
Fig. 2 is a vertical cross-sectional view of the band reel shown in Fig. 1 as taken substantially along the line 2-2 in Fig. 1.
Fig. 3 is a top view of the reel illustrated in Fig. 1.
Fig. 4 is an end view of the reel with the base thereof in section, this figure illustrating a loading position of the reel, and
Fig, 5 is a plan sectional View taken substantially along the line 5--5 in Fig. l, with the band reel omitted.
The reelrprimarily consists of a xed standard I and a movable standard I I disposed in parallel spaced relation by means of Va supporting base I2. Any suitable base may be employed to support these standards for movement toward or away from one another, but in the construction herein shown the base I2 is a welded sheet steel construction having longitudinally7 extending angles I3 and I4 joined by means of the box members I5 and I6. The box members I and I6 produce a very rigid base structure and also are so made as retainers for holding different metal seals of the type that are commonly employed in fastening the ends of the bands about the package or packing box to which the band material is being applied in cut lengths, or otherwise, from the reel.
The centrally disposed walls of the boxes l5 and I'are extended upwardly as shown at I1 and I8 in Figs. 1 and 2 to provide suitably spaced walls for supporting the uprights or standards IB and II. The standard Ill is iixedly secured to these walls while the standard II is pivotally secured thereto by means of a pin 20. The latter pin is readily removed by drawing out the cotter pin 2l and pulling the pin by its head end 22 and out of the aligned openings 23, a plurality of the latter having been provided in aligned and spaced relation in each of the walls I1 and I8 to permit adjustment of the pivotal point of standard II with respect to the standard I0 and to the base I 2. VWhen different widths of band `coils are being placed into the band reel, it is only necessary to shift the pin 2B into the necessary aligned openings to properly space the standard I I a sufficient distance from the standard IU for accommodating the width of band being used. Guide slots such as shown at 24 in Fig. 2 are also provided in the walls I1 and I8 of the box members for the purpose which will hereinafter be explained.
Various forms of mechanims may be employed for rotatably supporting the band coils, but in the present device the band coils are placed upon a spindle 25 suitably located substantially midway between the top and bottom of the standards IEI and II. This spindle, as best shown in Fig. 2, is located in a plurality of aligned openings, two of which at 26 and 21 being located in a bracket 28 and wall 29 of the standard I0 respectively, while the other two openings at 30 and 3| are in the wall 32 of the standard II and in the bracket 33 secured to the latter, respectively.' The spindle member 25 is secured to the standard ID by means of the pin 34 which passes through suitable openings in the bracket 28, and the head 35 of the pin will also help to hold the pin against displacement. The free end of the pin is preferably tapered or rounded as at 36 so as to readily receive the standard I I as the latter is moved toward or away from the standard I9 about its base pivot pin 2D. A cap 31 is suitably secured to the top end of the standard IIB, the cap being slotted as at 38 in Figs. l. 2 and 3 for the reception of the screw stud 39 which is carried by the bracket A!) secured to the standard II. A suitable fastening member such as a thumb screw 4I is connected with the stud and may be screwed down against the face of the cap member` 31 to 'hold the upright or standard II in the necessary parallel aligned relation for holding the band coil upon the reel spindle.
From the above description it is apparent that in swinging the movable standard II toward the fixed standard ISI and relative to the base I2, the
standard I l cooperates with the coil holding spindle 25 to hold the coil upon said spindle ready for use. It should be further noted that the oppositely disposed brackets 28 and 33 carried by the standards provide suitable abutments or bosses for centering a band coil between the oppositely related inner faces of the standards I and I I. Also, in connection with the cap member 31, it should be noted that suitable guide slots 42 are provided in each downturnedleg .of the cap whichare provided for the sam-e purpose as the previously described band guiding slots 24 in the Walls I1 and I8 of the box members.
As best illustrated in Fig. 1, a band coil shown at C in its entirety is pivotally supported on the spindle 25, the coil having its loose endsomewhat uncoiled and spiralling progressively outwardly and the terminal end of tlieband :is projected through one of the slots 42 in the cap member 31. In this manner the terminal end of the band B is lmaintained in Aa posi-tion where it will be readily available for usei-n'connection Vwith packing and crating andv it should also be `noted that although the coil C is -positioned -asshown in Fig. 1, the same may be reversed side for side with the terminal end of the-coil projected through the opposite opening-42 foruse at Athe opposite end of the reel. Similarly, the -coilC may be inverted with theloose terminal end-thereof passed through one or the `other "of the slots 24 depending primarily out ofwh-ich end of the reel the packerwishes to operate. Attention `is directed to the fact that the slots 24 and 42 are all elongated to accormnodate thedifferent yband widths,
but their effective -openings arev all determined by the amount of overlap-ofthe edge faces of the standard II when -in coil holding position as best shown in Fig. 2.
In order toprevent the-unraveling of the outer band coils of the reel -beyond the Ageneral con- Iines of the reel, suitablebraking means have been incorporated and supported on each of the standards Il) and II. These .braking members arie secured and carried `by each -of the'upright standards and are in the form of upper and lower pairs vof longitudinally .extending arms, the upper pair of arms being connected with standard IUan-d are designated as 43, and the lower pair of arms thereon are shown at 44, while the upper' pair of arms Vcarried 'by theV standard II are vshown at 45 with vthelower pair at 46. The pairs of arms 43, 4A., 45- and 46 are each contiguous'with the U-shaped plates 43', 44', 45", 46', such plates each being 4adapted to straddle the respective upright standards to which they -are fastened by means of spot welding as at 41 or by any other desirable method. Each pair of plates are also ribbed longitudinally as at 48- and such ribbing extends around the corners adjacent the upright standards and terminates-substantially flush with the outer faces of the plates connecting each respect-ive pair of arms.
As best shown in Fig. 1, Ythe outer extremities of the arms 4.3, 34, 65 and 46 terminate at spaced points radially disposed with respect to the pivotal mounting of the band coil. Each of the arms are provided at these terminal spaced ends with inwardly extending wings I) and 5! respectively, the wings 53 being carried by the arms connected with the upright I0, while the wings 5I `are carried by the arms on the upright standard I I. As best shown in Figs. 2 and 4, the Wings 5t and 5I are'all oppositely related and of such length as to overlap for allthe various `adjustments of standards-Il)y and II .Within the range of the various widths of band coils which can be carried by the reel of the present construction. The overlapping wings 50 and 5I are disposed in the path of any of the spiralling band coils which may result due to unraveling of the coil whenever the coil C over-spins during use.
In connection with the braking action supplied by the wings of the arms, it should be noted that the arms themselves are limitedly resilient and can be moved substantially against the oppositely disposed faces of the band coil C by the relatively movable upright standards I0 and I I, and held in this position by means of the thumb nut fastening against the cap 31. Al-
though the arms in the illustrations shown are in .longitudinal parallel relation, it should also be noted that the same may be constructed somewhat angularly disposed with respect to each `other by bending the same in an inwardly urged relation to Contact the coil C thereby braking over-spinning of theA coilv by such additional contact with the faces of the -coil as acquired by such inwardly disposed relationship. Merely the cooperative action of the arm ribs and the inher.- ent resiliency ofthe metal arms can produce the same result.
Since the band reel of the present construction has been devised to afford a complete unitary structure for packing and crating, a double looped strap iron 52 has been welded to the upright I0 as a means for supporting the necessary `crimping and applying tools which are used in connection with applying connecting'seals to the ends of the band when packing, such seals being conveniently located in .the xbox units I5 and I6 as heretofore described.
As the band reel Yhas been devised for stationary use or portable use, suitable openings 53 are provided in the angle irons I3 and I4 as best shown In Fig. 3 as means for securing the band reel to the floor or table adjacent the place of use. As a convenience for carrying the band reel about when portably used, a retractable handle 54 is connected with one of theupright standards as at I by having the ends of the handle passing through suitable openings in thecap 31 with the stops or nuts55 secured to the ends of the handle to limit the outward movement thereof. The handle 54 is illustrated in carrying position in Figs. 1 and 2, and in retracted and vinoperative position in Fig. 4.
It should also be noted that the band reel is practically of sheet metal construction throughout and is readily vassembled by spot welding and forms a very rigid and convenient band coil holding unit. Although uprights of any material or character may be employed, attention is called to Fig. 5 wherein the upright standards I0 and II are illustrated as preferably being of channel construction for enhancing the rigidity of the coil carrying reel.
The foregoing detailed description has been directed to the exemplary structural portrayal of the device of this invention as revealed in the accompanying drawings. Changes and deviations are contemplated, however, and the extent of such variation-s shall be only limited by the claimed concept of the invention as hereinafter set forth.
What I claim as new and desire to secure by Letters Patent is:
l. A band coil-:reel comprising a pair of coil supporting members one arranged-for movement toward and away from the other .and adapted for pivotaflly carrying a band coil, and cooperative upper and lower pairs of brake elements carried by said supporting members and extending beyond the circumference of said band coil, said brake elements being oppositely related with respect to the supporting members, respectively, and each cooperative pair having inturned Wings at their ends that overlap each other for coaction with the band to check the unraveling of the same during use.
2. A band coil reel having a pair of standards disposed in parallel spaced relation to each other, one of said standards being pivotally connected with relation to the other of said standards for movement toward and away therefrom, spindle holding means connected with said standards, adjustable means for changing the distance between said parallel standards to accommodate different Widths of band coils, and cooperative brake means carried by said standards to coact with the coil to prevent unraveling of the coil band Whenever said coil over spins, said brake means including inturned units that overlap each other to maintain said braking action during any of the allowable spaced positions of said standards.
