Application February 28, 1949, Serial No. 78,756
This invention relates to reeling devices, and more particularly, to, a device which is adapted to be. used for reeling, cutting and measuring lengths ofrbelting or other material which is normally formed in a flat; strip and transported and Stored in a cylindrical roll.
.Thehandling of elongated strips oi relatively tough material. "such as is used for conyeyer belting, transmission belting, stair treads, rubber matting, and the like, presents numerous dimculties; Such material is'fabricated in strips which may exceed five'feet' in width and which may be shipped from the, manufacturing plant in rolls, which weigh in excess of a ton.
The jobber who muststock many assortments of such material is faced with the problem of cutting relatively shortl'en ths of such material from a large roll when such lengths are ordered by customers; Heretofore, in cutting such lengths the; common practice has been to first remove the: roll from the place where; it is stored and roll the same; to an aisleof the W rehouse which is 'clear'of obstructions. The roll is then raised on afmandrel which is. placed through the coreof the roll by placing av jack under each end of the. mandrel and elevating the roll so, that it clears. the. floor. The end of the strip is then grasped'rby oneor several men and pulled away from the roll and carried down the aisle until "the desired; length has been removed from the roll. The. aislemaybe conveniently marked off infeet so that the desired length may be cut off when the strip is resting on the floor.
The obviousdisadvantage of this procedure is th'atthe aisleused for measuring the length of material'tobe out must-be keot clear at all times, thus, resultingin a lossof available storage space.
Another advanta e of'th above d c be procedure isfithahwhen large rolls of material are to he cut the manpower required to rotate the roll-is appreciable and is added to'the effort required o ca ry o d a e re vend. of t s rip e In the case of rubber belting or rubber covered belting the strip tends to stick to the roll, es pecially in warm weather', and further manual effort is often required for this reason. It is not uncommon tofind all the available manpower in a jobbers establishment pulling on a large roll of rubber belting'whenj theabove pro! cedure is followed.
Onelof the objectsofthisinvention isthe pro.-. vision. of'a reeling device which is economical to build and which may be employed to measure desired lengths o v mater al with lit le manu l effort;
Anotherobject e1} the invention is the pro-q vision of a reeling device which is relatively small and which may be employed in a small space.
Still another object of the invention is the provision of a reeli g device which permits the measuring of lengths of belting material without soiling the same to the extent, heretofore n eces-. sary.
And yet another object of the invention is the provision; of a reeling device for belting, and the like, which may be employed to out such material longitudinally into strips with great accuracy when narrow strips are desired from a wide strip.
Another object of the invention is the provision of adevice which is adapted to elevate a horizontal roll of belting from the floor on which it rests or todeposit such roll directly onto the floor and to support such roll for rotation while elevated.
Other objects and advantages will be apparent from the specification and drawings.

As best seen in Figs. 1 and 2 the device is supported on a wheeled base having longitudinal support members I, 2 and a cross member 3 integrally connected to said longitudinal members at one of their corresponding ends to form a U-shaped sup ort (Fig. 2).. At the ends of members I, 2 which are remote from the cross member 3 are wheels 4 secured to the base by means of brackets 5 (Fig. 1). Rigidly connected to cross member 3 are spaced frame members 6 equal distances from the center of said cross member which converge in a direction away from wheels 4 and are rigidly connected at their outer convergent ends by a transverse member 1. Integrally connected to member I is a. wheel support 8 which carries a caster wheel 9 n the longitudinal centerline of the U-shaped base (Figs. 1, 2). A conventional handle I9 is swingably secured to the axle of wheel 9 for pulling and guiding the device. (The end of the device carrying the caster wheel 9 will hereinafter be referred to as the forward end of the device, and in referring to the "left or right side of the device it will be assumed that the observer is looking forward.)
A pair of spaced opposed guides 29, 2| are rigidly secured perpendicular to support member I extending upwardly. therefrom (Fig. l), and another pair 22, 23 are secured in like manner to support member 2 in opposed relation to guides 29, 2!. These guides are adapted to support sliding blocks 24, 25 for vertical movement between said guides, and said guides are preferably structural channels positioned so that their backs are in spaced opposed parallel relationship (Fig. 2). A centering strip I9 is secured to the backs of the channels of each pair longitudinally of the same. A bolting plate 26 may be rigidly secured to the upper end of each pair of guides 29, 2| and 22, 23 (Fig. 1). Removably secured to these bolting plates 26 are cap plates 21 (Figs. 1, 2) which may be secured to the bolting plates by means of bolts 29. The cap plates each carry a pair of upstanding spaced lugs 39 to which a horizontal frame 3| is pivotally connected by means of bolts 32. This frame Si is generally U-shaped and comprises two longitudinal members 33 rigidly secured at their outer ends remote from lugs 39 to the ends of a transverse member 34 (Fig. 2).
As best seen in Fig. 1, this U-shaped frame may i be swung in a vertical are through 180 degrees from the full line position shown to the dotted line position 3| in which latter position it is substantially over the wheeled base and reduces the space required for storage of the device when not in use.
A bearing block 31 is releasably secured by bolts 38 (Fig. 3) to each end of longitudinal members 33 adjacent the transverse member 34. A pair of transverse rollers 39 (Fig. 3) extend between bearing blocks 31 and are rotatably supported in holes 49 formed in said blocks.- Transverse rollers 4! similar to rollers 39 are positioned under the latter and are rotatably supported in holes 43 in bushings 42, which bushings, in turn, are supported in the blocks 31 for rotation in holes 44. The holes 43 are offset from the center of bushings 42 so that by rotating both bushings 42 in like manner, the rollers 4| may be moved toward and away from rollers 39.
A set screw 45 (Figs. 2, 3) having a knurled bead, adapted to be actuated by the fingers is provided in each block 31 for the purpose of locking bushings 42 when the spacing between rollers 39 and 4| is set.
A pair of horizontally spaced square rods 41 (Fig. 3) are removably secured at each of their ends to bearing blocks 31 by means of set screws 48, and serve to support certain devices which will later be described in detail.
A square mandrel, generally designated 59 (Figs. 2, 7), extends between sliding blocks 24, 25 and is rotatably supported at its ends in these blocks (Fig. '7). The major portion of mandrel 59 is hollow, and consists of a section of square steel tubing 5|, and said section is provided at one of its ends With a journal 52 which is cylindrical except for a square portion 53 which is adapted to be inserted in tubing 5| and rigidly secured thereto, as by welding. The block 24 carries a bore 54 for rotatably supporting journal 52.
The end of the mandrel supported by sliding block 25 (Fig. 7) is provided with a solid cylindrical extension 55 which is rigidly secured to the end of tubing 5i, as by welding. This extension is provided with a dowel pin 56 which is rigidly secured through extension 55 so that each end of the pin projects outwardly from the extension 55.
The sliding block 25 is provided with a bore 51 in which is rotatably supported a sleeve 58. This sleeve 58 is cylindrical in form and is provided with a diametral slot 59 in its end facing towards mandrel 59. This slot 59 receives the projections of pin 56. The sleeve is also provided at the same end with a counterbore 6| which receives the end of extension 55. A square hole 62 is provided in the opposite end of sleeve 58 coaxial with counterbore 6| for receiving a driving shaft for rotating the sleeve 58 and'mandrel 59, as will be described later in detail. Secured to the side of sliding block 25 which faces toward the mandrel 59 is a plate 63 (Fig. 8), for the purpose of preventing longitudinal motion of the mandrel 59 in sliding blocks 24, 25.
The plate 63 is pivoted at one of its ends to sliding blocks 25 by means of pin 64 and is provided with an arcuate edge 65 which is adapted to be received in a peripheral outwardly opening groove 66 in extension 55. When the edge 65 is received in groove 66 (Fig. 8) longitudinal motion of the mandrel 59 is effectively prevented. When the plate 63 is swung upwardly out of groove 66 the shaft may be removed by passing it through bore 54 in sliding block 24. A weighted portion 61 may be provided on plate 63 to urge the edge 65 into the slot 66 at all times.
For the purpose of raising and lowering man drel 59, a parallelogram linkage, generally designated I9, is provided coacting with each of the sliding blocks 24, 25 (Fig. 1). Each linkage comprises a relatively long, horizontal bar H which is pivotally connected at one end to its associated sliding block by means of bolt 12. Each sliding block may be provided with a slot 13 for re-' ceiving the bar H (Fig. 7). y I
The horizontal bar If is pivotally secured at their ends opposite bolts 12 to the upper ends of a pair of relatively short vertical links 14, a pair of which are positioned on opposite sides of each link H and secured thereto by means of pin 15. Another pair of links 16 are pivotally secured to each bar H intermediate its ends by means of pin 11. The pairs of links (4, l6 extend downwardly from bar I I. A horizontal bar I8 parallel to bar H connects the lower ends of links 14 and 16 at each side of the frame and is connected to links I6 by means of pin 19. Both bar 18 and links [4 are secured at their point of connection to the ends of a transverse lifting shaft 89 (Fig. 2) which is positioned forwardly of mandrel 59 and over cross member 3. The bar I8 is provided with a square hole which receives a square portion of the shaft 89 (Fig. 9) and both links 14'- are provided with round holes so that the same are pivoted on shaft 89, while bar 78 is secured to shaft 89 for rotation therewith (Fig. 9).
The shaft 89 is supported for rotation on bearing s 83 which, in. turn, are rigidly secured to cross exeeizsa member -:A downwardly iprzigtecting' linki84 is rigidly secured to shaftifln zcentr'allyfor. the'isame and is connected with the piston rod 89:: iof: :a hydraulic jack lifi by means-of clevi'sififi and bolt 81. The jack 85 is of theiconventional:hydraulic type having a manually actuatable handle 88.
Thus, it is seen that actuation-"of the jack so that the shaft 89movesrearwardly o'f th'et base :will cause the sliding blocks 24,15 to move up while opposite motion-of the jack will caus'e the blocks 24, 25 to move downwardly- Since the jack will be slightly inclined during such movements, it should be pivotally connected to the cross mem her 3, as by pin fifl.
As best seen inFigs. 1, 2, the deviceis adapted to beused with. a horizontal roll of material 93 supported for rotation on axmandrel 194. which, in-turn, may be raised andl'owered by means of conventional jacks 95 or which may be permanently held elevated on bearings.
In operation, the strip of material'96on roll 93 is preferably and ordinarily removed fromthe bottom of roll 93,. as shown incFig. 1, and then passed betwen rollers 39 andAI. The rollersl'l may then be moved upwardly toward. rollers--39 by means of. the eccentric bushings 42 until rollers 4I contact the. strip 96 with whatever degree of pressure is desired. The end of the'strip isthen started: around acore'Sl'I mounted on mandrel 59. This core ispreferably cylindrical and equal in length to the widthofthe strip tobe reeledand is provided'with a square hole therethrough for receiving the square portion 53 of the mandrel 50.
For the purpose of rotating mandrel 50, an electric reversing motor I Ilflis. provided (Fig. 2) which drives through a reducer IIJI. A simplified drive arrangement may'be-efiected by employing the type of vertical motor which is mounted integrally with the housing of thefredu'cer, as shown in Figs. 1', 2, and which-reduceris-providedwith a horizontal driven shaftzprojectingvfrom' one of its sides, such as the shaft'shown-at I03 in Fig. 7. The drive unit comprising the motor I00, and reducer IIII may be secured to plate I04, which, in turn, may be bolted to block 25 by means of bolts I 05. The bolt 12 which is employed as'apivot for one of the bars H mayalso be'used to secure-the plate I04on block 25, as shown in Fig. 7.
Thus, it is seen by this arrangement that a direct drive may be used to transmit torque to mandrel 50 without the useof splined shafts and other devices which would necessarily beemployed because of the vertical adjustment required to blocks 24, 25.
When the device is employed to measureoff a desired length of belting, a conventionalcounter such as commonly known to the trade as a Veeder-Root counter I It], may be employed ha ing a wheel III which isplaced inengagement with the surface of the belting to be measured, and which rotates as the belt moves forwardly between the rollers 39 and 4!. The lineal measurement (preferably infeet) is indicated on the dial I I2 which is visible to. the operator at all times. The counter may be secured to one of rods 41 in any convenient manner; as by clamps II 3 (Fig. 2). It should be noted in thisconnection that the wheel III of the counter I-IU' should be positioned between the rollers 4 I so that no vertical motion of the belt 9" is possible which might impair the accuracy of measurement.
For the purpose of preventing transverse-motion of the belt 96, a pairof vertically disposed rollers II5 (Figs. 2, 3) are provided=oneach side of the belt-9B. As best seen-in-Fig. 6, thes'e-rollersare 6. rotatablymountedIon'pins IIB by means ofbear ing l- I 1 (Fig. 7):. Thepinsi I6, in .turn', are rigidly securedto a cross piecet I I8 vwhichiisno'tched as at H9, to receive the lowercorner of the square rods 41. In asimilar manner, a cross piece I20 is notched as'at. I21, to receive the upper edge of square rods 41. This'cross piece I29 is centrally apertured toreceivea bolt I22 which .threadedly engages a threaded aperture I23 in cross .piece H 8. A'knurled'head I24'may be provided onbolt I22 so thatthe same maybe tightened by hand.
The above described .unit, generally designated I15,may be adjustablypositioned on square rods 41 by means of bolt 122- to suit the particular width of belting to be cut, and when properly positioned, prevents any transverse motion of the belt while the same is being reeled. This becomes important when the beltis being cut longitudinally, in which case, uniformity in width of the cut 'strips is insured.
For the purpose of cutting the. belting into longitudinal strips a unique cutting device, generally designated I29, is provided: on the square bars 4'! (Fig. 2). Although only one suchv device is indicatedLinFig. 1,:it is obvious that any num-' ber may be employed, depending. on the number of strips to be cut.
The cutting device (Figs. 4, 5) comprises in part, a pair of spaced support members I30 rigidly secured to a cross member I3! .at one of their ends'and to a cross member I32 at their other ends. The c'rossmember I 32is' notched, as at I33 (Fig. 5) to receive oneo'f the horizontally directed edges of square rods 41. Between the two square rods 4'Iis agenerally rectangularlplate I34 having its opposite ends notched. as at I85, to receive the square rods 41. The notches I35 should be formed so that the plate I34 may slide easily along the rods 41 when the plate I34 is not clamped to said rods.
Depending from plate I34 and rigidly secured thereto, is'a relatively large boss I36 having a central bore in whicha cylindrical knife holder I 31 is 'slidably received. This knife holder is diametrally slotted at its lower end to receive a relatively flat knife blade I38 which may be removably secured to the knife holder I3? by means of screws I39. To prevent the'knife holderlfrom rotating in'the boss I36 a keyway I48 is formed longitudinal ofthe-knife holder I 31 for receiving a projection I4I on a stop element I43 rigidly secured to plate I34.
Thedepthof this keyway is gradually reduced adjacent the upper end of the knife holder. I 3! to form a cam surface I42 which coacts with projection 1 4i 'to prevent downward movement of-knife holder I3'I.'
Diametrically opposite thecam surf-ace I4I on knife holder I3'Iis'a radiallyoutwardly opening slot I43 whichis adapted to receive the tapered end of an elongated keeperbar E44. This keeper bar isprovideda't'its end'opposite thetapere'd'end with a block I45 to which said keeper bar is rigidly secured. The block I45 is notched on one side to receive oneof the square rods 47 and is provided on its opposite side with a bore 5-45 to receive the reduced end of a clamping boit m. The cross member I3I is threadedly apertured to receive the bolt I47, and a knurled bead I43-on bolt" I4? permits thelkeeper I44 to'he readily removed fromslot I43 and the block 545 moved out of en'ga'gement with square rod 47. A slot I50 may be provided in keeper bar I44 for receivi'ngh bolt I5I" which, in turn, is threadedl y secured to plate I34 to hold' the knife holder downwardly against the resistance of the belt.
Thus, it is seen that upon actuation of bolt I41 the keeper may be removed from the knife holder and the device unclamped from the square rods in one operation. Thus, the knife holder 131 is readily removable for blade replacement and the device is easily moved along the square rods as desired for cutting different widths of belting.
The simple means herein described permits rapid cutting of a large belt into two or more strips of any desired width with great accuracy and without requiring more than one operator. It is pertinent to note that belting is taken to the device and removed from the same in a form which is easily rolled and is never handled in unwieldy long strips.
After the desired length of belting has been reeled on the mandrel 50 and the free end of the strip is secured to the .roll in any convenient manner, the roll is lowered so that it rests on the floor, thereby permitting withdrawal of mandrel 50 through the bore 54 in sliding block 24.
There may be as many cores 97 on the mandrel 50 as there are strips to be out. If merely a winding operation is performed, one core is all that is required.
The use of this invention permits the jobber to fill orders for various regular sizes of belting by stocking only the largest widths which may be cut to the smaller sizes. If an irregular width of belting is desired, it is a simple matter to out the next larger size to suit.
The embodiment herein described is not to be construed as restrictive of the invention, but merely a preferred form thereof.
