TAPE-GUIDIN G MEANS FOR GO0DS-ROLLING MACHINES.

Specification of Letters Patent.

Patented Aug. 6, 1912.

Application filed December 20, 1911. Serial No. 866,998.

Goods-Rolling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to cloth rolling machines, and has particular reference to machines of this class adapted for the doubling and folding or the rolling of double width cloth into bolts, but is not restricted to such use as the features thereof may be used in any connection for which they may be adapted or appropriate.

One object of my invention is to improve upon the mechanism described and claimed in my former United States Letters Patent No. 962,193, dated June 2]., 1910,for feeding a measuring tape between the folds of the goods during the winding thereof in rolls or bolts, whereby to reduce to a minimum the liability of breaking the tape during an operation of the machine, increasing its efficiency of operation, and enhancing the practicability and commercial value thereof.

In the use of machines of this character it has heretofore been the practice, so far as I am aware, to wind the cloth in flat form upon flat core members, such as wooden boards, or the like, the members being continuously rotated atsubstantially uniform speed during the winding operation, thus imparting an irregular pulling or jerking action to the cloth, which causes a wrinkling and uneven winding thereof, especially during the initial portion of the winding of a bolt. This jerking action also causes a frequent breaking of a measuring tape being wound with the goods.

An object of my invention is to provide an improved process and means for winding cloth upon bolt boards or cores whereby the cloth may be wound thereon in substantially cylindrical form and then removed from the winding mandrel and collapsed or flattened upon a core piece which is disposed therein during the winding operation, thus avoiding the objections above noted.

The invention is fully described in the following specification, and while the fea tures thereof in their broader aspects are capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a plan view of a machine embodying the invention. Fig. 2 is a front end elevation thereof. Fig. 3 is an enlarged plan of a portion of the guide bar over which the measuring tape is fed between the folds or strips of the goods being rolled. Fig. 4 is an enlarged side elevation of a portion of the mechanism for guiding and controlling the movements of the measuring tape. Fig. 5 is a cross-section thereof on the line x x in Fig. 4. Fig. 6 is a detail partly in section of the sectional spool on which the measuring tape roll is mounted when placed in the machine. Fig. 7 is an enlarged perspective View of a portion of the tape guiding mechanism. Fig. 8 is a longitudinal section of the'winding mandrel in collapsed position with the cooperating expanding wedges in association therewith and one in section. Fig. 9 is a similar view thereof with the mandrel expanded and partly in section. Fig. 10 is an end view of the mandrel carrying a core member with a quantity of goods wound thereon. Fig. 11 is a perspective view in collapsed or flattened form of a core member comprising one feature of my invention, and Fig. 12 is an end view thereof in collapsed state with a quantity of goods wound thereon.

In illustrating the features of my invention I have shown them in association with a well known type of cloth doubling and folding machine, in which 2 is a drum under which the cloth or goods passes to the winding parts after being doubled by the means provided for such purpose, 3 the shaft of such drum which is journaled at its ends in suitable bearings in the side frame pieces or standards 4t, 4t, and 5, 5 are the shaft sections which are provided with suitable means for gripping or engaging the part or means upon which the goods is wound, said shafts being suitably journaled in axial alinement in theopposite frame pieces 4, 4 and driven at uniform speed from a drive shaft 6 by suitable chain and sprocket or,other suitable connection therebetween. One of the shaft sections 5 is mounted for free reciprocal movements in its bearing to adapt it to be axially moved relative to the other shaft section to engage or release the goods winding member or mandrel carried therebetween, longitudinal movement for such purpose being imparted thereto by the turning of a screw 7, which is anchored in a stationary frame part of the machine and is threaded through an arm 8 which fixedly projects from the movable shaft section, as shown in Fig. 1.

9 designates the usual guide bar, which projects from one side piece of the frame laterally of the machine in advance of the drum 2 in position for its free end to work between the folds of the goods prior to the engagement thereof with said drum as is Well understood in the art. Mounted for longitudinal reciprocal movements on the top of the bar 9 is a tape guiding strip 10, which has its upper surface preferably channeled, as shown in Figs. 3, L and 5, and is provided in the base of its channel with a longitudinally extending groove 11 through which a retaining screw 12 freely projects and threads into the bar 9. Projecting downward from the side edges of the guide strip 10 for sliding movement along the bar 9 are a pair of arms 13, which are connected at their lower ends beneath the bar 9 and carry a swivel tooth or tracer 14 Fig. 4 for working in the grooves of a multiple return groove cylinder 15, which is suitably mounted in bearing arms 16 pro jecting downward from the bar 9. The cylinder 15 has slow rotation imparted thereto from the drive shaft 6 through any suitable intermediate gearing or connection, as best shown in Fig. 2, said connection in the present instance comprising a belt 17, which connects a small pulley 18 on the shaft 6 to a larger pulley 19 on a shaft 20, and a small sprocket wheel 21 on the shaft 20, which is connected by a sprocket chain 22 to a larger sprocket wheel 23 on the cylinder 15. It is apparent with this mechanism that when a machine is in operation the cooperating action of the grooved cylinder 15 and tooth 14; will impart a slow reciprocal movement to the tape guiding strip 10 for the purpose hereinafter described. The tooth 14: is yieldingly held in engagement with the grooves of the cylinder by a coiled expansion spring 24 which is mounted-in a socket therein and has its upper end thrust against the bar 9, as shown in Fig. 5.

The channel of the tape guiding strip 10 is closed at its top by an arm or capping strip 25 which is preferably hinged to the free end portion of the guide bar 9, as at 26, to enable it to be raised from over the strip 10, and is of sufficient length to extend substantially the entire length of the guidestrip 10 when resting thereover. A catch 27 is pivoted to the inner end port-ion of the bar 9 and is adapted to releasably cooperate with a pin projecting from a side of the free end portion of the arm 25 to retain such arm in closed position, as best shown in Fig. 4:.

The roll 29 from which the measuring tape 30 unwinds is carried by a suitable spool, the shaft ends or trunnions of which are mounted in bearing slots 31' provided in the bearing arms or standards 32, '32.

which rise in laterally spaced relation from the inner end portion of the bearing arm 9, or stationary part 9 from which it projects. The bearing arms 32, 32 are preferably of a yielding or flexible nature to facilitate a relative lateral adjustment thereof as the width of the tape roll may require. A bolt 33 connects the upper ends of the bearing arms 32, 32 to facilitate an adjustment thereof. The bearing slots 31 of the bearing arms 32 are of suitable form to permit a quick insertion or removal of the spool trunnions therefrom.

It is found in practice that it is quite important to the proper feeding of the tape to the goods that some means be provided for acting thereon after unwinding from the tape roll 29 to resist a too free feeding thereof to the cloth. For this purpose I interpose a plurality of tape guiding rolls between the tape roll 29 and its point of entrance to the guide strip 10, said rolls being alternately arranged to guide the tape to have a zig-zag course of movement. These guide rolls comprise lower and upper sets 34 and 35, respectively, the rolls of the lower set being suitably journaled in a carrying chair or frame part 36, which is mounted upon the top edge of the inned end portion 9 of the guide bar 9, while the rolls of the upper set are carried by bearing arms 37 which are pendently attached to a flexible carrying bar 38. The bar 38 is hinged to one end portion of the frame part 36, as at 39, and is provided at its opposite end with a catch 40 or other suitable means for releasably engaging the associated end portion of the frame 36. hen the bar 38, which carries the set of rolls 35, is in the closed position shown in Fig. 7 its rolls alternate with the rolls 34 and extend below the plane thereof whereby a passing of the tape over the rolls 3 1 and under the rolls 35 causes the same to have a zig-zag course of movement. The bar 38, which carries the rolls 35, is preferably of a flexible nature to allow it to have a springing action as the tape is drawn between the coacting sets of rolls, as it is found that the action of the tape feeding means is improved by this arrangement.

The tape 30, after passing through the channel in the guide strip 10, extends down ward over the outer end thereof through a reglsterlng open ng in the guide bar 9 and is given a quarter turn, as indicated at 30,-

due to its passage through a narrow slot which is provided in a guiding member 41 attached to the bar 9, as shown in Fig. 2. The tape then passes with the goods under the roll 2 and is wound therewith upon the mandrel or other winding part of the machine. The openings in the bar 9 and member l1 through which the tape passes in its downward course from the guide strip 10 are of suitable length to permit a lateral movement of the downwardly extending portion of the tape therein lengthwise of the bar 9 as the guide strip 10 is moved by the grooved cylinder 15 for such purpose. The moving. of the tape in this manner causes a distribution of the tape throughout a predetermined area of a roll lengthwise thereof to prevent the ridge which would be formed thereby in the roll if the tape wound in the same plane thereon. With this arrangement no ridge occasioned by the winding of the tape within the goods is perceptible in a complete roll.

The spool upon which the tape roll 29 is mounted is shown, in the present instance, as comprising the two sections 42 and 43 which have cooperating telescoping hub portions 44 and 45 respectively projecting from their inner sides, and each has a trunnion 46 projecting axially from its outer side. The parts 44 and 45 have their surfaces preferably squared or of irregular form in cross-section to cause them to turn in unison. In using this form of spool the hub portion 44 of the member 42 is first inserted within the axial opening of the tape roll 29, being of suitable size to fit therein, after which the part 15 of the member 43 is inserted within the part 44 from the opposite side of the roll and the spool with the roll thereon may then be placed between the bearing standards 82, 32 with the trunnions 4L6 resting loosely in the hearing slots 31.

In lieu of the flat board or core piece which is customarily gripped between the ends of the shaft sections 5 for the winding of the goods thereon in flat form, as is now customarily the case, I provide a mandrel 50, of substantially cylindrical form, for such purpose, a core part 51 of a collapsible nature being first mounted thereon. To permit of an easy insertion of the mandrel into or removal of the same from within the core part, the mandrel is composed of a plurality of parts capable of relative movements to expand or contract the size of the mandrel. In the presentinstance, the mandrel is shown as comprising two sections a, a which cooperate to form a substantially cylindrical exterior and are connected in a suitable manner by contractile springs b to normally maintain such parts in collapsed or retracted state. Dowel-pins 0 are also shown as projecting from one of the mandrel parts and working within registering sockets in the other part to guide the relative movements of such part.

52, 52 designate wedge blocks, which are carried by the shaft sections 5 at their inner ends (taking the place of the jaws commonly used in machines of this class for gripping the ends of bolt-boards), the wedge ends of such blocks being intended to removably fit into the complemental sockets 53 provided in the respective ends of the mandrel 50 between the sections a, 64 thereof, whereby a forcing of the wedge blocks into such sockets will effect a separation of the mandrel sections and a consequent expansion of the mandrel, as indicated in Fig. 9. The surfaces of the mandrel sections with which the wedge blocks coact are shown as being faced with metal strips 54, one of which has an extension 545 projecting without an end of the mandrel to provide a finger-grip to facilitate a withdrawal of the mandrel from a roll of goods and its core-piece 51.

The core-piece 51 is composed of any suitable stilf or firm material of a flexible nature, which is rolled or shaped in hollow form in cross-section to permit an insertion of the mandrel 50 therein, the core-piece being slightly larger in diameter than the mandrel in its collapsed state for such pun pose. It is found in practice that corrugated board with the inner facing strip omitted therefrom, as shown in Figs. 11 and 12, makes a very satisfactory core-piece, as it is sufficiently flexible to permit a shaping thereof in circular form without breaking its outer surface or crinkling its inner surface, and is at the same time sutliciently stiff to form an excellent core-board or member when collapsed or flattened for such purpose. It is apparent that this makes an exceedingly cheap core-piece, which can be thrown away when once used, or repeatedly used if desired; and that, in addition to very materially facilitating a winding of the goods in both form, obviates the use of the customary wooden bolt boards, which are continually becoming more expensive due to the growing scarcity of wood.

The operation of my improved goods rolling machine and the carrying out of my improved process of rolling the goods first in circular form and then collapsing the same in flat bolt form is as follows: The operator after placing a core-piece 51 over a mandrel 50, places such mandrel between the expanding blocks or wedge members 52, 52, carried by the shaft sections 5, 5, with the mandrel sockets 53 in register therewith and then turns the screw 7 to move the attached shaft section 5 toward the other shaft section to effect a consequent forcing of the wedge blocks 52 within the respective mandrel sockets to expand the mandrel to entirely fill the encircling core-piece so that the mandrel and core-piece will rotate in unison upon operating the machine. This having been done the operator places a tape roll 29 within the bearing arms 32, 32, if one is not already positioned therein, and passes the tape over the set of rolls 3a and channel strip 10, and thence down through the opening in the guide bar 9 and attached part 41 between the folds of the goods being rolled to pass therewith under the drum 2 and thence to wind together upon the core-piece carried by the mandrel 50. When the tape has been positioned in this manner the cappiece. or arm 25 is lowered and secured in position to close the top of the channel strip 10 and the spring bar 38, carrying the set of tape guiding rollers 35, is lowered in the closed position shown in Figs. 2 and 7 with the rollers carried thereby projecting down between and alternating with the cooperating guide rolls 34. \Vhen the length or bolt of goods has been entirely wound upon the receiving core-piece 51, the shaft sections 5, 5 are relatively moved by the screw 7 to permit a removal of the mandrel 50 and sur rounding parts from the machine. The release of the expanding blocks 52, 52. from engagement with the mandrel permits the sections thereof, under the influence of the contractile springs b, to collapse or recede from expanded relation, thus releasing the mandrel from within the core-piece to permit an easy withdrawal of one from the other. \Vhen the mandrel has been withdrawn from the corepiece the operator presses upon the bolt to collapse or flatten the core-piece and goods wound thereon in the form shown in Fig. 12. During the winding of the goods upon its core-piece the measuring tape, which is wound with the goods, is caused to gradually change its position lengthwise of the roll by the action of the multiple groove cylinder 15 upon the guide strip 10 thus distributing the tape over a predetermined area of the roll longitudinally thereof to prevent a noticeable bulging of the roll due to the thickness of the tape.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

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