MACHINE FOR FILING- TEXTILE FABRICS.

Specication of Letters Patent.

Application filed June 22, 1911. Serial No. 634,660.

To all whom may concern:

Be it known that I, CHARLES J. Pninsrnn, a citizen of the United States, and a resident of Hackensack, in the county of Bergen and State of New Jersey, have invented a new and Improved Machine for Filing Textile Fabrics, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a machine of the character set forth having means for carrying rolls of cloth in such manner as to avoid stretching or otherwise placing under tension the cloth as the same is laid or disposed for cutting; to provide in a machine of the character set forth a mechanism for measuring the cloth as the same is delivered from the said machine; to provide a brake sufliciently sensitive to prevent the operation of the measuring mechanism subsequent to the stopping of the machine; to provide in a machine of the character set forth means for controlling the guiding of the cloth whereby the cut ends are disposed accurately in line; to provide in a machine of the character set forth bearing supports for the rollof cloth'and means for balancing the roll on said bearings; and to provide in a machine of the character set fort-h a hoisting mechanism for elevating the roll for placement on the carrying mechanism.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a side elevation vof a machine constructed and arranged in accordance with the present invention; Fig. 2 is a longitudinal vertical section taken on the line 2-2 in Fig. 3; Fig. 3 is a front elevation of the machine showing the cloth as being fed therefrom; Fig. 4 is a detail view, on an enlarged scale, showing a side view of a pointer plate used in conjunction with the measuring mechanism; Fig. 5 is a cross section taken on the line 5 5 in Fig. t; Fig. 6 is a detail view, on an enlarged scale, showing the end of a guide rule and a brake mechanism for controlling the same; Fig. 7 is a detail view, on an enlarged scale, of the end of the cutting block and guide therefor; Fig. 8 is a cross section taken on the line 8-8 in Fig. 7 Fig. 9 is a pictorial view showing the machine as carryin a roll of cloth and indicating the manner o piling the same; Fig. 10 is a similar view, showing the machine as piling linings which are folded; Fig. 11 is a cross section of the mechanism for expanding the roll, the section being taken on the line 11-11 in Fig. 12; Fig. 12 is a longitudinal section of one of the heads of the mechanism for expanding the roll and operating key therefor, the section being taken on the line 12-12 in Fig. 11; Fig. 13 is a detail View in cross section, and on an enlarged scale, of the end of one of the expanding bars, the section being taken on the line 13-18 in Fig. 11; and Figs. 14: and 15 are views of a modified form of the mechanism for expanding the roll of cloth prior to mounting on the piling machine.

To eifect the purposes for which the present invention is designed the machine is arranged to, first, expand the rolls of cloth to be piled and to balance the same to avoid mechanical pounding; second, to lift the rolls thus expanded and balanced in supported relation upon the machine; third, to draw the cloth from the roll without exert-- ing a stretching strain thereon; fourth, to cut the cloth accurately to aline the cut ends thereof to form an even pile; and, fifth, to measure the cloth during the operation of piling the same.

The present machine is employed in factories where a long cutting table A is provided, whereon the cloth B is laid in piles, as shown in Figs. 9 and 10 of the drawings. In the usual hand operation the cloth is thus piled by manually lifting upon the table A a piece or roll of cloth, one end of the cloth being secured at one end of the table, and the piece is then rolled to the opposite end and cut at a mark provided on the table. The piece is then reversed, the free end secured, and the piece is rolled back to the first station, the lay being severed, and the piece again .reversed for rolling out a third lay, and so on. This operation vis laborious and necessitates the employment of a number of operatives. v

To employ the present invention the table A is provided with a channeled track 20 adjacent one edge of the said table. The opposite edge of the said table is preferably Patenteainay 7, 1912.

finished with a fiat strap track 21. Over these tracks the machine is carried on the

wheels

22, 22.

rlhe wheels

22, 22 are pivotally mounted on the

side frames

23, 23. The frames 23 are held in rigid disposition by the

cross bars

24, 24 and 25 and tie rods 26 suitably disposed. At the upper edge of each of the side frame 23 are recesses 27, provided for the reception of the stud shafts formed on the piece expande'rs, which provide a bearing for the same during the Aunwinding process hereinafter set forth.

Adjacent the recesses 27 the frames are provided with stud shafts 28, on which are rotatively mounted the carrying wheels 29. The wheels 29 are provided with any suitable bearings, the object of which is to reduce the friction on the wheels. To lift the pieces to supported position upon the wheels 29 I provide the hoisting bars 30, there being one at each side of the machine connected by a cross bar 119, each being mounted'in a standard 31. At the free ends of the bars 3() are provided pins 32 to which are secured the ends of the chains 33. The free ends of the chains 33 are provided with snap hooks 34, or other suitable devices for feeding over the bearing shafts provided for carrying the piece. Pivotally attached to the opposite ends of the bar 30 is an extension bar 35. The extension bar 35 is pivoted at 36 upon the bar 30, and is provided to extend the length of the power application end of the bar 30. The purpose in thus pivotally connecting the two bars is to provide a means for lifting the extension bar 35 to an out-of-the-way position during the operation of piling the cloth.

As shown in Fig. 2 of the drawings, the piece is wrapped on the usual board C. Prior to lifting the piece from the table A, the spreader rods 37 are inserted between the cloth and the board, and at opposite sides thereof. The rods 37 extend beyond the ends of the piece to receive the sockets 38 provided at one end of the two

expansion bars

39 and 40. To aid in threading the sockets over the ends of the rods 37 the said sockets are flared, as seen best in Fig. 13 of the drawings. The sockets 38 are preferably rigidly secured to the expanding

bars

39 and 40, which bars are mounted to extend through perforatio-ns in a head 41, as seen best in Fig. 11 of the drawings. The

bars

39 and 40 are each provided with rack teeth 42, and in the side of the said bars opposite that provided with the teeth 42 is formed a groove 43. The pintle end of t-he screws 44 is extended in each of the grooves 43 to maintain the relative disposition of the

bars

39 and 40 and the sockets 38 provided thereon. Meshed with the teeth of the said rack is a pinion 45. The pinion 45, as shown in Fig. 12, is iixedly mounted on the end of a short shaft 46. The shaft 46 is pinned to the handle 47, the cross bar 48 of which is provided to turn the key or handle, as in winding. Suitable housing in the head 41 is provided for all of the movable members connected therewith. One of the members is a ratchet bolt 49, the bevel end whereof extends into the path of the teeth of the pinion 45 to engage the same in a manner similar to the pawl and ratchet and arranged'to act when the pinion is turned in one direction only. The bolt 49 is provided with a spring 50, the operation whereof seats the engaging end of the bolt in engaged relation with the teeth of the pinion. To release the bolt 49 from engagement with the pinion 45 an eccentric lever 51 is provided, the operation of which retracts the bolt from engagement with the pinion 45 when the said lever is depressed. The rods 37 are each provided with a series of nicks, as shown best in Fig. 13 of the drawings, to receive ratchetwise the beveled end of the pawl bolt 52. The bolt 52 is suitably mounted in each of the expanding

bars

39 and 40, as seen best in Figs. 11 and 13 of the drawings. To seat the bolt in the nicks provided in the rod 37 is a spiral spring To lift the bolt from engagement with the rod 37 a lever 54 is provided. the free end 55 whereof is extended through the perforation in the bolt 52. The lever 54 is pivoted at 56 in a small standard extended from the

bars

39 and 40.

In the operation of preparing the pieces for the present machine the rods 37, as stated, are extended through the piece from end to end, being placed for this purpose between the cloth and the board of the piece. The expanding bars 39 and 40 are adjusted to register the sockets 38 with the ends of each of the rods 37. To facilitate this adjustment the lever 51 is depressed to lift. the bolt 49 from engagement with the pinion 45, the handle 47 being thus free to rotate to equally expand or retract the

bars

39 and 40 and the sockets 38 carried thereby. When the sockets have been adjusted the head 41 is forced against the rods 37, the bolt 52 engaging the nicks therein to hold the same against withdrawal from the sockets 38. Vhen both ends of the rods 37 are thus engaged by the expanding bars the handles 47 are rotated, the lever 51 being adjusted to permit the bolt 49 to engage the teeth of each of the pinions 45. then the two ends of the piece have been expanded to the same degree it will be found that the piece, when suspended upon the stud shafts 57, is balanced. It will be understood that the stud shafts 57 form the bearings on which the spreader frames and the piece of cloth rotate. For this purpose the stud shafts 57, as shown best in Fig. 1 of the drawings, rest upon and between the wheels 29, forming thereby a substantially frictionless bearing for said st-ud shafts. The piece being now in condition for mounting on the wheels 29 the snap hooks 34 are passed over the handles 47, the bar 30 being depressed for that purpose. The operative now grasps the handle of the extension bar 35 and thereby lifts the end of the bar 30 and the piece at the end of the chains 33, until the stud shafts 57 pass over the inclines 118 to be deposited thereby upon the wheels 29. llVhen the piece is in this position the cloth B is drawn therefrom and passed over the drum 58. The drum 58 is provided with stud shafts 59 set out from each end thereof, which stud shafts are mounted in bearings formed in the extensi-on arms G0. Each arm 60 is provided with a slot- G1 through which bolts 62 are extended, said bolts being thread engaged with perforations provided in the standards 31, as seen best in Fig. 2 of the drawings. Adjacent one end of the drum 58 the shaft 59 has iixedly connected thereto a gear pinion which is meshed with a gear wheel G4. The gear wheel 64 is rigidly mounted on a short shaft carrying a worm gear G5, the thread whereof is engaged with the teeth of the worm gear wheel 66. Mounted on the shaft of the gear wheel 66 is the upper one of the spools 67 on which is wound the metallic ribbon 68. The train of gears thus described is proportioned to transmit by the rotation of the drum 58 a rotation of the spool 67 adapted to move the ribbon G8 at a speed the rate whereof is fixed in ratio to the trave-l of the cloth. In correspondence with the ratio thus mentioned the rule bar G9 is engraved to equal divisions, certain of the said divisions bcaring numerals indicative of the number of units over which the pointer plate 70 travels when attached to the ribbon. As indicated in the drawings, the rule bar provides for indicating any number from O to 100. In the operation of the machine the numerals are distinctive of yards. Thus the comparative rates of speed of the periphery of the drum 58, which is the rate of travel of the cloth B, and the rate of travel of the ribbon G8, is such that the plate 70 would pass from 0 to 100 while the 100 yards of cloth is laid by the present machine. It will be understood that the marl;- ings are arranged to compensate for the length of cloth extending from the drum 58 past thecutting block 71 to the anchorage of the cloth on the table.

As shown in the accompanying drawings, particularly in Figs. 4 and 5 thereof, the plate 70 is provided with a back 72 and a swinging clamp lever 78 which is mounted on standards 74. The nose ofthe lever 7 3 extends through a slot provided in the plate 70 to impinge upon and clamp the ribbon 68 which passes between the plate 70 and the back 72, as seen best in Fig. 5. Between the plate 70 and the back 72 is also slidingly disposed the rule bar 69 and the guide bar 75. The plate and back are held in separated relation by the filling strips 76. This construction adapts the machine for shifting readily and quickly the plate 70 to accommodate the employment of the measuring mechanism here described. Thus, if in the .operation the piece contains 125 yards it will be seen that by the operation of the measuring mechanism when the plate 70 is carried to the 100 marlr it must be shifted back to the 0 mark. This is accomplished by lifting the lever 73 and then using the said lever as a handle, sliding the plate over the ribbon r68 until the pointer of the plate 70 is opposite the 0 index, when the lever is lowered to the position shown in Fig. 4 and the operation of the machine is resumed. a

It is essential when using the measuring mechanism above described that the drumA 58 should cease to feed the cloth instantly the machine is arrested. For this purpose the drum is provided at the one end with a V-groove 77. Into the V-groove 77 is extended a short section of round belt brake 78. See Fig. 6 of the drawings. One end of the brake 7 8 is anchored at the end of the arm 79, said arm being ixedly attached to and extended from the guide bar 75. See Fig. 1 of the drawings. The free end of the brake 78 is attached to a thin blade 80, which is normally interposed between the cloth and the drum 58. The blade 8O is pivotally mounted by means of the bolt 81 upon a bracket 82, and is provided with an extension 88 having at the end thereof a pin 84 provided to receive a weighing device 85. The weighing device is removable to permit devices of Various weight to be employed. The weighing device 85 is calculated to overbalance the weight of the material extending between the said blade and the piece 7. By means of this arrangement provision is made for stopping the drum 58 and measuring mechanism connected therewith, and at the instant of the last end of the cloth passing over the drum 58; or, in the event that the material should become broken, or that two lengt-hs of cloth should be wound on the same piece. The braking action is the result of the lift of the brake 78 into the V- groove 77.

The cloth B, when drawn from the drum 58, is passed under the roller 86 and between the rollers 87 and 88. The roller 88 is provided to press lightly upon t-he cloth when piled, and upon the top of the layer of the pile just previously placed on th-e said pile. By this method any trapped air is removed from between the layers of cloth or fabric. To regulate the pressure of the roller 88 upon the cloth, said roller is mounted upon the bars 89. At the ends of the bars 89 is provided a counterbalaneing weight 90. The weight 90 is increased or diminished to diminish or augment the pressure of the roller 88 upon the cloth. Disposed between the bars 89, and mounted on the slot 91 formed therein is the cutting block 71.

The table A is provided with a stop post or block 92 disposed in the path of the machine, and at the limit of travel thereof. It is desired that the lengths of cloth should be cut accurately. For this purpose the machine is provided with the guide plates 93 secured to each of the side frames 23. Vertically disposed in the plates 93 are the slots 94. The slots 911 are provided, as seen in Fig. 7 of the drawings, to receive the slide blocks 95 and to guide the same. The blocks 95 are set out from the arms 96, which arms 96 4are pivotally connected with the cutting block 71, the same being provided with short end shafts extended through the slots 91 of the bars 89. The block 71 is provided with two slots which assist in the operation of cutting the cloth. The slot 98 is formed adjacent and in line with the side of the straight edge 99. Then the cutting blade is pressed upon the cloth, using the straight edge 99 to guide the same, the blade extends through the cloth into the slot 98. It is to hold the clot-h during this operation of eutting that the straight edge 99 is provided with the pricking points 97, which pricking points extend into the second of the above mentioned slots formed in the block 71, when the straight edge 99 is superposed upon the said block 71. The straight edge 99 is provided with side arms 100 which are hinged at 101 to the bracket arms 102 set out from the block 71. In the normal position of the block 71 and the straight edge 99 the `latter is thrown back out of contact with the cloth. rlhe cloth at this point extends from the roller 86 to the roller 88. lVhen, however, the machine, as shown in Fig. 2 of the drawings, is at the end of its travel and has been stopped by the block 92, the straight edge 99 is thrown forward upon the cloth, the prieking points 97 passing therethrough, and the straight edge resting firmly upon the block 71 secures the cloth in position. The operation of cutting is now performed. Due to the travel of the block 95 in the slot 9st of each of the plates 93 the cutter block 71 and the slot 98 therein are maintained constantly in the same vertical plane independent of the rise or fall of the roller 88. As shown in Fig. 9 of the drawings, when the machine is returned from the position shown in Fig. 2 to the opposite end of the table, the cloth is threaded under the auxiliary roller 103 and is laid thereby on the pile, as shown by dotted lines in said figure.

In Fig. 10 of the drawings is shown means 'for support-ing a small table 104, whereon may be placed piles of folded cloth. This is the condition, as above stated, in which linings are generally handled. I have taken occasion in the illustration in Fig. 10 to show how, with a machine of this character, two piles of linings could be laid on the table at the same time. The table 104- is provided with a hook 105 which extends over the cross bar 24.

In Figs. 14 and 15 is shown a modilied form of expander for the piece. In this form the blade 106 is rigidly connected with astud shaft 107 and is adapted for secure ment in a similar shaft 108. The shafts 107 and 108 are each provided with a wedgeshaped plate 109. rllhe free end of the blade 106 is serrated to form a ratchet toothed section 110, with the teeth whereof a ratchet bolt 111 engages. The bolt 111 is held in operative position by a spring 112, and is provided with a head 113 whereby the said bolt may be lifted from engagement with the section 110.

In the operation of the modified form of the invention the blade 106 is extended through the cloth beside the board C, the wedge-shaped plates 109 passing within the cloth and forcing the same outward to center the shafts 107 and 108 to balance the piece for mounting on the machine. Irovision is made to automatically trip the lever 73 on the plate 70 when in the course of operation the said plate has been lifted to the point opposite the maximum or 100 lay mark on the bar 69. A cam 1111 is mounted on the guide bar 75 which extends under the lever 73 to lift the same to release the ribbon 68 as the point of the said plate arrives in line with the 100 mark. It is to receive the plate when the same falls or slides down the ribbon 68 that I have provided the lever 1 15. The lever 115 is pivoted and is normally held in the position shown in Fig. 1 of the drawings by means of a spring 116, which spring yields under the impact of the blow of the falling plate 70 to return the same to the lifted position where the pointer of the said plate alines with the 0 mark on the rule bar 69. At the lower end of the bar is mounted an undercut cam member 117, arranged to engage the lever 73 to operate the same in a manner the opposite of that of the cam 1141: at the upper end. lhen the plate 70 is released from engagement with the ribbon 68 by the cam 111, it falls to the lower end of the bar 75, the end of the lever 73 passing inside of the cam member 117, which deiiects inward the lever 73 to force the end of the said lever to engage the ribbon 68, clamping the same between the head of said lever and the back 72. The interval of time occupied in the drop of the plate 70 and the rengagement thereof with the ribbon 68 is of very short duration.

I-Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent is l.
