This invention relates to a belt handling and cut-off machine.
The invention has application to the handling, measuring, and cutting of any at strip material which is kept in rolls, for example, woven fabrics, rubber, or leather, and is particularly well-suited for handling rubber and leather belting, such as conveyor belts and transmission belts. The standard factory roll of belting is approximately 500 to 600 feet long, but almost all retail sales of belting are for shorter lengths. More than 75 per cent of the retail sales demand is for strips 50 to 250 feet in length. In every case where a length shorter than the full roll is desired, the
retailer must measure accurately the desired length from the long stock roll, cut it off', and make a new roll from the cut-off strip. The problem of doing this accurately and without dirtying or injuring the belting has long existed in this art.
This invention solves the problems heretofore existing and replaces the cumbersome, ineflicient, and costly procedure now prevalent. The current practice is for several men to lift the heavy stock roll from its storage position, carry it or roll it on the loor to a convenient place and unroll some of it on the door, in lengths as long as possible. They measure the unrolled length with a tape measure, mark the place, and attempt, usually with mediocre success, to roll up the measured portion in an even roll. Then they carry this rolled-up portion across the floor as they unroll some more belting from the original roll, measure it, mark it, and roll it up, continuing this tedious n process until the desired length has been measured. Then one of them, using a kmetal straight edge as a guide, severs the belt by hand with a sharp knife. This process is fraught with inacf curacies; in addition, it wastes warehouse space,
requires the time and strength of several men,`
and gets the material dirty from contact with the floor.
One object of this invention is to provide a belthandling and cut-01T machine which can be op- Another object of the invention is to provide a machine, operable by a single man, which will enable him to measure belting and deliver it to a customer more quickly than several men can do vwithout the machine Another object of the invention is to provide a machine which .makes it possible to save time, labor, and space in the operations of delivering a measured roll of belting and at the same time perform the operating better, with again in accuracy in measurement and with a perfect line of severance free from fraying.
Other objects and advantages of the invention will be apparent from the following description and from the drawings, in which:

Fig. 5 is a detail view of the cut-off table taken along the line V-V of Fig. 3;
Fig. 6 is another detail view of the cut-off table taken along the line VI-VI of Fig. 5.
Fig. 7 is'a view'in section along the line VII- VII of Fig. 5.
Considered broadly, the machine includes a main frame lil mounted on wheels or casters 2l and having a truckfloor brake 22 by which the machine can be locked at a chosen location. A pair of rigid uprights 3u, 3| and 32, 33 adjacent `each end of the frame i, support the mechanism by which the rolls of belting ,'25 are raised and lowered. The lifting may be done by a cable means, a threaded means, or some other equivaient means.
The brackets 134 are slidable on the uprights and `have bearings il@ to support the axles A1 which carry the rolls of belting. Preferably there is a braking means i8 on the brackets ifi to control or to stop the rotation of each axle 'i. The axle 4l `which supports the core 54 onto which the new, measured' roll 'HJ is to be wound has a crank f by which the belting is rolled up.
Mounted on the lower frame l0, somewhere between the two lifting means, is a measuring and cut-off table I5. Bars or rollers I6, |1, 84, and 85 are supported in the frame I0 adjacent the table I to flatten and to align the material passing over it. A meter 93 is mounted on a rod 90 over the table |'5 in such a way that it can be swung down over the belting to measure it and can be swung o-ut of the way after the length has been measured (see Figs. 1 and 5). When the meter 53 is swung out of the way aV hold-down clamp 98 may be inserted to hold the belting 25 firmly against the table I5; then, through a slit 83 in the table I5, directly below the place where the meter 93 measured the length, a knife blade |86 is moved to sever the belting with a perfect, straight, clean cut.
The steel frame I0 ispreferably symmetrical, though not necessarily so. As illustrated in Figs. 1 and 3, two strong L-shaped side plates and I2 are held together and braced by the cross braces |3, I4 and by the cut-oil table l5, which may be bolted, riveted or welded together. The cylindrical bars |6 and |'1 may be similarly secured to the frame I0 or they may be pivoted in the side plates and I2 at I8 for free rotation therein.
Adjacent each of the four corners of the frame I0 is a bracket 20, in each of which is mounted a'caster 2|. The casters on one end are preferably swivel mounted. A truck floor brake 22 may be fastened on the bottom of each of the base bars I| and |'2 near the end with the swiveled casters. When the foot lever 23 of the brake 22 is pressed down, the brake shoe 24 is forced against the iloor and holds the frame l0 in a fixed position on the floor. A slight upward pressure by the operators toe against the bottom of the lever 23 releases the brake so that the frame I0 again may be moved about on the wheels 2|.
The four corner uprights 3D, 3|, 32 and 33 are here made from U-beams placed in an upright position adjacent the four corners of the frame I0 and are secured to the side plates and I2. The diagonal brace beams 34 are also secured to the side plates and I2 and the horizontal thrust beams 35 are secured at one end to them and at the other end to the upright U-beams 36, 3|, 32 and 33. Each pair of uprights 38, 3|, 32 and 33 is also braced at the top by a cross bar 36.
Two bearing supports on top of each cross bar 36 support the shaft 4| for free rotation. In the embodiment illustrated in Figs. l and 2 a drum 42 is keyed to each shaft 4|v adjacent each end. One end of the cable 43 is fastened to the drum 42, and the cable 43 winds or unwinds around the drum 42. The other end of the cable 43 is fastened to the bracket 44 which slides freely in thevertical slot 45 formed by the inside of the U of each of the beams 3U, 3|, 32, and 33.
Each bracket 44 is provided with a semicircular bearing recess 46 in which a cylindrical shaft or axle 41 may turn. The clamp 48, which provides a means of braking, controlling, or preventing the revolution of the axle 41, is pivoted at 58 on the bracket 44 so that it can be swung back to the position shown in dotted lines in Fig. 1 when the axle 41 is being inserted or removed. When the clamp 48 is down over the axle 41, the stud 5| in the bracket 44 passes through the perforation in the clamp 48, and the wing nut 52 is threaded on it. By tightening or loosening the wing nut 52, the pressure of the clamp 48 on the shaft 41 may be increased or decreased and the freedom of rotation of the'shaft 41 is thereby controlled.
A large sprocket wheel 55 is keyed to the shaft 4| and a smaller sprocket wheel 51 is keyed to the shaft 58. The shaft 58 is journaled in the plates 59, which are secured to the braces 34 and 35, and a ratchet wrench 66 or crank may be placed over the keyed'end 68a of the axle 58. The drive chain 56 passes around the two sprocket wheels 55 and 51 to form a reduction gear system by which the handle 68 may be used to revolve the shaft 4|, thereby causing the drums 42 to wind up or unwind the cable 43 and thus to raise or lower the brackets 44, the axle 41 and the roll 53 of belting 25 supported thereon.
The modified form of device illustrated in Fig. 4, and at the right hand end in Fig. 3, is preferred where there is a very heavy load which might tend to overstrain a cable. Each slot 45, formed by the U-shape of the beams, partially encloses a vertical shaft 6| on which there is a thread 62 extending from near its bottom end to the point 63 a little more than half way up. The vertical vshafts j6| are journaled in the cross bars 36,and on their ends above the bars 36 bevel gears 65 are keyed. Keyed to the shaft 4| and in mesh with the bevel gears 65 are the bevel gears 66. The shafts 4I may have sprocket wheels like the wheels 55, 51 (Fig. 1) for a reduction gear system such as that previously described, or the ratio of the bevel gears 65 and 66 may give sufilcient mechanical advantage so that the shaft 4I can be rotated directly by the ratchet wrench 68 attached to the keyed shaft end 61.
In this modied form of device the supporting brackets 44 may be the same as those previously described, except for the internally-threaded collar which rides on the thread 62. Identical gears 65, 66 are used for each bracket, so that each pair of brackets 44 remains parallel when they are raised or lowered. Other means, such as a hydraulic ram, for lifting and lowering the rolls of belting may be provided. The important thing is to have a type of lifting means which is supported by the frame I0, so it can be moved into position to pick up a roll of belting 25 from the floor or from a shelf, and can then lift the roll into a convenient position where it may roll or unroll freely.
Preferably a reduction gear apparatus is provided to assist in winding the roll 1I! of measured belting. Fig. 1 illustrates a reduction gear apparatus suitable for this purpose. The 55 larger toothed wheel 1| is keyed to one end of the axle 41. A bracket 12, bolted on the U-beam 32,
supports for free rotation a short shaft 13, to
which are keyed the smaller geared wheel 14 and the crank handle 15. The teeth on the wheels 1| and 14 are engaged and the dog 16 locks the u axle 41, except when the dog 16 is purposely lifted.
When the handle 15 is turned counter-clockwise the belting 25 is wound onto the shaft 41. As the material is pulled from the old roll 53, it forms the new roll 10. It is Very convenient for the operator to stand beside the machine and turn the crank 15 while-watching the measuring dial 93to know when he has reached the desired point to cut off the belting.
The cut-off table I5 (see Fig. 5) is divided by the slit 83 into twoaligned portions 8| and 82, both of which are preferably nat plates secured on top of the U-beams 18 and 13, which are in turn secured to the side plates and |2.
Adjacent each edge of the cutting table I5 is a cylindrical bar 84, S5, whose top surfaces are approximately level with the table surface l5, and beyond each of these are the cylindrical bars IS, |1 whose bottom surfaces extend a little below the top of the cutting table. All `four of these bars I5, |1, 84 and 55 are supported betweenthe side plates and l2. They may be bolted to the plates I! and l2 or they may be pivotally supported therein at I8 for free rotation. On each of the bars l5 and l1 are two guide collars 86, each of which has a set screw 81, so that the collars 86 may be moved along the bars and set for any Width of belting 25 to pass between the guide flanges 88.
After the roll of belting 53 has been lifted into a position where it is free to rotate, the outside end of the belting 25 is brought from the roll 53 and passed under the roller |5 between the guide flanges 88 and then over the top of the bar 84. From there the belting 25 is brought across the cutting table i5, over the bar85, under the roller |1 between guide flanges 8B, and then up to the shaft -41 preparatory to forming the new roll 15. The bars or rollers |65, il', t4 and B5 align the -belting properly with respect to the table lI5 and the slit 83, and make it lie substantially flat against the surface of the cut-olf table.
The side plates and l2 also support the rod 90,which is above and parallel to the slit S3 and on which may slide or rotate the collar 5|. arm 92 attached to the collar 9| supports the meter -93 at its other end. The collar 9| is shiftable and enables the meter 93 to be lowered into position on the belt 25 at-any desired location across the width of the table |5. Since the rod 9D is parallel to the slit v83, the-wheel 34 of the meter 93 contacts the belting 25 exactly over the center of the slit 83, whenever the meter 93 is swung down to the belt. In `this way `the meter reads the amount of belting material 25 which has passed the point 53 where it is to be cut.
The meter 93 is a standard item, preferably of the type whose rotatable vwheel 54 has a roughened periphery 95 to engage and be tur-ned by the surface of the belting 25. lThe exact circumference of the disc 94 may be some convenient stand-ard distance, such as one foot. Bye, structure well known in the measuring art, rotation of the wheel 54 produces a, calibrated reading on a dial or an indicator 95 and shows the distance the periphery 55 of the wheel 94 has been moved by the belting 25.
When the indicator 96 on the meter 93 shows that the desired length of belting 25 has passed by the slit 83 the brakes 48 may be set, and the arm 52 which holds the meter 93 is lifted oif the belt 25 and swung back around 'the rod 9i] into the position shown in Fig. 5. The holding bar 98 can then be placed in position along one edge of the slit 83 to hold the belt 25 tightly against the table l5 While the knife '50 severs the beltmg.
The tapered. end 5| (Fig. 6) of the holding bar 98 is inserted into the stationary-pivot clamp |53 at the side of the table opposite the operator, and bears against it at some point alc-ng the taper |0|, according to the thickness of the belting being cut. The rectangular end |04 of the bar 93 is inserted in the adjustable clamp |05, which `is then tightened, and the bar 93 presses the belt 25 firmly against the table top |5.
The shaft H5, mounted directly below the slit 83, has a screw thread ||I, on which the internally threaded knife holder ||2 rides and by which the knife blade |00 is impelled along the the slit 83.
slit 83. The knife `III!) may be moved by a motor orlby hand. As illustrated in Fig. 6 the crank Vhandle I3 :and the geared wheel |4 are keyed to the shaft H5, which is journaled in the bracket housing |16. The geared wheel |l4 engages the smaller geared wheel H1, which is keyed on the shaft Hlysotha-t when the ycrank handle ||3 is turned, lthe threaded shaft H0 rotates, Vand the collarfl-IZ, bearing the knife 455, is moved along Since the bar 93 holds the belting 25 -rmly anchored on the table |5, the knife blade |50 Vcuts through it in a perfectly straight line, Vleaving no frayed edges or irregularities. Moreover, i-t cuts exactly at the spot where the meter 93 has measured the length of the belt 25.
In operation the machine is wheeled on its casters 2| up to the stock roll of belting 53 and is-locked there by the brake 22 in a position where the roll 53 is evenly spaced between the upright-s 35 and 3|. The brackets 44 are lowered below the center of the 'roll 53. An axle 41 and a core 54 `to which the axle 4l is keyed are inserted through the center of the roll 53 with its ends projecting beyond the V-uprights S5 and 3|. Then the f brackets 441are'raised enough to engage the ends of vthe :axle 41 in the bearings 45. The clamps 4S may then be swung down over the axle 41 and tightened'to give the desired freedom of rotation. The brackets 44, axle 41, and roll 53 are then raised off the oor by the lifting mechanism. If the location of -the machine is inconvenient f or the cutting operation, the machine may then be wheeledwherever desired and secured there by the brake :22. y y
portionI of the belting 25 is then unrolled and fed in under the bar l5, over the bar 84, and over the cutting table l5 to the center of the slit 83. The wheel 94 of the meter S3 is then brought down and placed on top of the edge of the belting-.25 vwith `its dial set at a zero reading. Then the material .is measured as it is pulled over the rest of the -table I5, over the bar 85 and under the -bar-I 1 tothe second core 54 on which the new roll 1U is to be formed. After the belting 25 is fastened on the second core 54, the crank 15 may be turned counter-clockwise to wind up the desired `amount of Abelting onto the new roll 10.
When the desired length has passed underthe meter 9-31, Vthe geared wheel 1| on the axle 41 is locked by the dog 15 to `hold the roll 1|] in place, andthebrakes '48 may be tightened if desired. The meter v93 is swung out of the way, and the holding bar 98 is placed in position. The crank handle I|3 is Vthen turned to move the knife blade |55 .in the slit 83 and the belt is severed. The holding bar 98 is then lifted away, and the free end of the belting 25 is rolled up on the second roll 1|). If vno further belting from the roll 53 is needed, the free end of that roll 53 is also rewound, and the stock roll 53 may be returned to its storage position. The measured roll 10 may be wheeled to the desired location where it can be wrapped' for storage or delivery to the customer.
In the preferred form of the invention, the cutting means is provided; however, the cutting means may be done by hand before or after the desired amount of material has been measured Vonto the roll 10.
' By means of the foregoing device, I have provided a machine operable by one man, which can be wheeled up to a stock roll of belting weighing thousands `of pounds, lift the roll onto the machine, measure off part or all of the roll while forming the measured part into a roll on the 7 other end of the machine, sever the belting at an accurately determined length, lower the measured roll onto a truck for delivery to the customer and then return the stock roll to its storage bin.. I-Ieretofore all these operations have been done much slower and mostly by manual handling at great cost for labor; and if a lightcolored belting was involved, usually with the dealer ending up with the customer accusing him of selling second-hand belting because by the time the men were through measuring, cutting and rolling it around on the floor, it was dirty and rendered useless for many purposes.
While, for purposes of compliance with the statute, I have shown a preferred form of apparatus, I do not intend thereby to limit this patent to that particular form of apparatus or to forego equivalents except as is required by the claims.
