- My apparatus obviates the use of through metal shafts or spindles for the support of rolls of paper, ordinarily known as web rolls, as such spindles are heavy and have to be handled manually into and out of the central tube or core of said rolls, therefore causing extra effort, expense and delay.
- my mechanism obviates the above objections and to these ends it is provided with a pair of rotatable cone members, which project slightly into the ends of the fibre or paper core or tube, which forms the central portion of the roll of paper and on which the paper is wound at the paper mill.
- These cores are generally provided with metal ferrules on their end portions, so as to properly receive the cones above referred to and prevent deformation of the paper tube core, or the paper on account of the great weight of the roll of paper and the shocks due to its handling and rotation.

- the inner end 5 of the plunger 4 preferably comprises a number of concentric cylindrical portions adapted to receive a rotatable cone member 6 mounted on a pair of roller bearings 'I which are adapted to permit the easy rotation of -not shown, in order to cooperate with a key or said cone member and by reason of the inclined positions of the axes of the rollers they are also adapted to receive end thrusts, due to the pressure of the cone 6 against the web roll.
- a partial cross section of part of the paper roll is indicated at 8 and this roll is wound upon the paper or fibre tube or core 9, each end of which is preferably protected by a metal ferrule 1.0, Which is placed or forced on the end of said tube, thereby compressing it slightly to more securely hold it in place.
- This ferrule 10 re-enforces the end of the tube 9, and prevents its distortion or bending when the heavy roll of paper 8 is mounted on and rotates with the. cone member 6.
- This metal ferrule 10 is also adapted to receive the trust of the cone 6, which is suflicient to hold the cone in position, centrally against the end of the web roll and also to resist the lateral or bursting pressure of said cone.

- a clockwise rotation of the crank 28 without axially withdrawing the handle will allow the pawl 30 to successively engage the teeth 35 as usual in such cases.
- a clockwise revolution of the crank 28 will project the plunger 4 and its attached cone 6 from the retracted position shown in Fig. 5 to the forward or engaging position shown in Fig. 4 and a reverse revolution of the crank 28 with the pawl 30 disengaged from the teeth 35 will retract the plunger 4 and its attached parts.

This is done when the cone 6 is in the position, indicated in Fig. 4, but when the paper has been substantially unwound from the roll 8.
- crank 28 When the empty core tube on its supports is in the non-supplying position, the crank 28 is turned counter-clockwise by the handle 29 and by reason of the varying angularity of the movement of the link 20 with the axis of motion of the slide rack 17, the first part of the withdrawal motion will be comparatively slow and forcible, while the latter part of the movement is faster and of less force, whereupon the parts then assume the withdrawn position indicated in Fig. 5.
- the crank 29 is turned in a clockwise direction until the parts assume the position in Fig. 4.
- the first portion of this movement is very rapid, due to the large angle between the lines of movement of the rack slide 17 and that of the longitudinal axis of the oper ating link 20, but toward the latter portion of the forward movement, that of the plunger 4, and its attachments, becomes less and less for a corresponding upward movement of the slide rack 17, so that with a slight and substantially uniform rotating speed and force manually applied to the crank 29 the cone 6 is first quickly and then more slowly but more strongly forced toward and into operative position in and against the end of the tube core of the web roll, and when this is accomplished the front end of the paper on the web roll 8 is secured to the rear end of the previous web, now off its tube, and is thereby drawn into the printing machine.
- Certain features of my invention consist in means for obtaining a long movement of the support cone, that is, to the extent of several inches, and in a certain case a movement of about 4 inches or more is provided, and as this long movement is accomplished by one of the support cones, the opposite and companion cone at the other end of the roll, can be constructed as a simply rotatable cone which need not be fitted with mechanism, of the character described and illustrated herein, to move it axially into engagement with extent, and on release of this longitudinal pull, the spring 31 will cause the pawl to project and engage with the teeth 35 of the curved rack 34.
- crank handle being substantially a plain cylinder with beaded end, conduces to the ease of operation of the handle as compared with other handles, which have detent or pawl levers, which must be grasped at the same time as the handle.
- Another feature resides in the fact that with a comparatively substantially uniform force, which may be manually applied to the handle 29 to rotate the shaft 23 when the parts are in the position shown in Fig. 5, a quick outward movement of the plunger first takes place and with an approximately uniform speed of rotation of the shaft the outward movement of the plunger and its attached parts becomes progressively less and less, and by the time the cone 6 begins to contact with the ferrule 10 of the core tube 9, the movement is small but the applied force is multiplied many times to produce a firm contact and insure the exact centering of the cone in the end of the tube core, so that its axis substantially corresponds with that of the core and the web roll.

New York, N. Y., a'corporation of New York; Irving Trust Company,
receiver Application January 23 6 Claims.
This invention relates to improvements in web roll supports for use in connection with printing machines and has for its object the provision of apparatus whereby rolls of paper may be rotatably supported andwhen the paper is used from a roll a new and complete roll of paper may be promptly and easily'substituted in place thereof.
My apparatus obviates the use of through metal shafts or spindles for the support of rolls of paper, ordinarily known as web rolls, as such spindles are heavy and have to be handled manually into and out of the central tube or core of said rolls, therefore causing extra effort, expense and delay.
On the other hand, my mechanism obviates the above objections and to these ends it is provided with a pair of rotatable cone members, which project slightly into the ends of the fibre or paper core or tube, which forms the central portion of the roll of paper and on which the paper is wound at the paper mill. These cores are generally provided with metal ferrules on their end portions, so as to properly receive the cones above referred to and prevent deformation of the paper tube core, or the paper on account of the great weight of the roll of paper and the shocks due to its handling and rotation.
By reason of the simplicity of its construction and operation, my improved apparatus saves time, labor and expense in the interchange of web rolls and it is, therefore, valuable in these respects.
With the foregoing and other objects in view, which will be hereinafter more fully explained, this invention resides in the combination, arrangement and details shown and described herein, it being understood that various changes maybe embodied within the scope of what is claimed, without departing from the spirit of the invention.
Having thus given a general description of the objects of my invention, I will now, in order to make the matter more clear, refer to the three sheets of drawings in which like characters of reference refer to like parts:-
Fig. 1 is an end elevation showing my mechanism mounted near the end of one arm of a spider, preferably adapted to support several web rolls on pairs of different arms, these spiders being arranged in spaced and adjustable pairs; Fig. 2 is a side elevation thereof with certain parts omitted; Fig. 3 is a sectional elevation on the line IIIIII of Fig. 2; Fig. 4 is a sectional elevation on the offset line IVIV of Fig. 1,
, 1932, Serial No. 588,301
also showing a longitudinal section of the end of a roll of paper and my rotatable support in position for operation; Fig. 5, is a view similar to Fig. 4, but showing the rotatable support in its retracted position and out of engagement with the end of the roll of paper; Fig. 6 is a partial sectional elevation taken on the line VIVI of Fig. 5 and Fig. 7 is a partial sectional elevation taken on the line VII-VII of Fig. 1.
Referring now to the numerals on the various parts of the drawings:-
1 is the outer portion of the arm of a spider which, and its companion spider, may each have a plurality of arms adapted to be rotated about a central shaft or support and to receive a roll of paper, and by rotation place it in position for supplying its web to a printing machine.
The preferred form of spider may comprise a plurality of supports of the character described, so that while one roll of paper is in use and the Web therefrom is being fed to the printing machine, another core tube, from which the paper has been completely or substantially unrolled is on an adjacent pair of spider arms in position to be removed and replaced by a new and complete Web roll. V
A pair of these spiders are used, one for each end of the web roll and in order to provide for paper of different widths the spiders of each pair may be arranged nearer together or further apart longitudinally ofthe web roll and so adjusted and secured. In order to align the paper properly and deliver it to the printing machine both of the spiders carrying the web rolls may be traversed and adjusted longitudinally of the Web roll axes, thereby bringing the edge of the paper into position to receive the impressions with uniform and proper margins.
On the end of the arm 1 of the spider is an enlarged hub portion or housing 2 provided with a substantially cylindrical opening or bore 3, the axis of which, when in use, practically corresponds with that of the web roll.
Mounted within the bore is a slidable or reciprocable member or plunger 4 which is shown generally and externally of cylindrical form and is adapted to be projected toward and, retracted from the end ofthe central portion or tube core of the web roll. This plunger may, however, be of any suitableshape, such as square, rectangular or otherwise. The inner end 5 of the plunger 4 preferably comprises a number of concentric cylindrical portions adapted to receive a rotatable cone member 6 mounted on a pair of roller bearings 'I which are adapted to permit the easy rotation of -not shown, in order to cooperate with a key or said cone member and by reason of the inclined positions of the axes of the rollers they are also adapted to receive end thrusts, due to the pressure of the cone 6 against the web roll.
A partial cross section of part of the paper roll is indicated at 8 and this roll is wound upon the paper or fibre tube or core 9, each end of which is preferably protected by a metal ferrule 1.0, Which is placed or forced on the end of said tube, thereby compressing it slightly to more securely hold it in place. This ferrule 10 re-enforces the end of the tube 9, and prevents its distortion or bending when the heavy roll of paper 8 is mounted on and rotates with the. cone member 6. This metal ferrule 10 is also adapted to receive the trust of the cone 6, which is suflicient to hold the cone in position, centrally against the end of the web roll and also to resist the lateral or bursting pressure of said cone. of the roll core 9 may be provided with a keyway,
projection on the companion cone to prevent slippage of the-roll on the cones and to cooperate with the tension or adjusting means for the paper as it is unwound. The rear or outer end 11 of the plunger 4 is provided with recesses or cutaway portions 12 and 13 to receive and permit the operations of other parts of my mechanism, and this produces the bifurcate end portions 14, which are provided with the slots 15, through which the shaft 23 passes, as indicated in Figs. 4 and 5. The lower end portion of the hub is also provided with an opening or cutaway portion 16 to allow the operation of other portions of the mechanism.
At the rear portion of the hub is mounted a slide 17, preferably formed as a rack with teeth as illustrated and having a pair of lugs 18 in which is mounted the wrist pin 19, while another wrist pin 21 is mounted in the plunger 4. On these wrist pins the operating link 20 is mounted and adapted to be swung by the movement of the rack slide 17. A pinion 22 is mounted and secured on the shaft 23, while apair of guide links 24 are loosely pivoted on the shaft 23 and on the central pin 25 of the operating link 20.
These links 24 serve to guide the operating link 20 while it is swung by the movement of the rack slide 17 and the pinion 22 and to balance or counteract'the thrust of operation.
In order to retain the rack slide inoperative positions, a retainer and guide 26 therefor is provided, secured to the hub or housing by the screws 27. On the outer end of the operating shaft23, a crank 28 is keyed. The crank handle 29 therefor, has a pawl, detent or latch 30, a spring 31 for holding it in engagement with the teeth 35 of the curved rack 34 and a sleeve 33 and a rod 32 are provided and so attached to the other parts that the axial withdrawal of the handle 29, for a short and limited distance, will disengage the pawl 30 from the teeth 35, and on release, the pawl 30 will again engage with one of the teeth 35 of the curved rack. A clockwise rotation of the crank 28 without axially withdrawing the handle will allow the pawl 30 to successively engage the teeth 35 as usual in such cases. a
A clockwise revolution of the crank 28 will project the plunger 4 and its attached cone 6 from the retracted position shown in Fig. 5 to the forward or engaging position shown in Fig. 4 and a reverse revolution of the crank 28 with the pawl 30 disengaged from the teeth 35 will retract the plunger 4 and its attached parts.
With an approximately uniform speed and pressure applied manually to revolve the crank 28 in a The ferrule on the other end clockwise manner, the cone member 6 will move quickly at first from the position shown in Fig. 5 to that shown in Fig. 4, but by reason of the linkage and the toggle effect thereof the speed of projection of the cone will gradually decelerate while the force will progressively increase, thus conducing to speed of operation, while applying the maximum pressure when needed to forcibly engage the cone 6 with the end of the tube core.
Having thus given a description of the various features of my mechanism, the following further description of its operation will be of interest:
The web roll having been axially mounted upon a pair of supporting cones and the web or paper having been substantially unrolled therefrom, the spider is rotated to bring the depleted core or tube into non-supplying position, while presenting a fresh roll of paper on another pair of arms of the spider to the printing machine. This is done when the cone 6 is in the position, indicated in Fig. 4, but when the paper has been substantially unwound from the roll 8. When the empty core tube on its supports is in the non-supplying position, the crank 28 is turned counter-clockwise by the handle 29 and by reason of the varying angularity of the movement of the link 20 with the axis of motion of the slide rack 17, the first part of the withdrawal motion will be comparatively slow and forcible, while the latter part of the movement is faster and of less force, whereupon the parts then assume the withdrawn position indicated in Fig. 5.
A. new full roll of paper, indicated as 8, is then placed in position with one of its ends supported on a similar cone 6, not shown, whereupon the parts are in position as indicated in Fig. 5.
After the parts of the web roll are positioned as indicated in Fig. 5, the crank 29 is turned in a clockwise direction until the parts assume the position in Fig. 4. The first portion of this movement is very rapid, due to the large angle between the lines of movement of the rack slide 17 and that of the longitudinal axis of the oper ating link 20, but toward the latter portion of the forward movement, that of the plunger 4, and its attachments, becomes less and less for a corresponding upward movement of the slide rack 17, so that with a slight and substantially uniform rotating speed and force manually applied to the crank 29 the cone 6 is first quickly and then more slowly but more strongly forced toward and into operative position in and against the end of the tube core of the web roll, and when this is accomplished the front end of the paper on the web roll 8 is secured to the rear end of the previous web, now off its tube, and is thereby drawn into the printing machine.
Certain features of my invention consist in means for obtaining a long movement of the support cone, that is, to the extent of several inches, and in a certain case a movement of about 4 inches or more is provided, and as this long movement is accomplished by one of the support cones, the opposite and companion cone at the other end of the roll, can be constructed as a simply rotatable cone which need not be fitted with mechanism, of the character described and illustrated herein, to move it axially into engagement with extent, and on release of this longitudinal pull, the spring 31 will cause the pawl to project and engage with the teeth 35 of the curved rack 34.
The crank handle being substantially a plain cylinder with beaded end, conduces to the ease of operation of the handle as compared with other handles, which have detent or pawl levers, which must be grasped at the same time as the handle.
Another feature resides in the fact that with a comparatively substantially uniform force, which may be manually applied to the handle 29 to rotate the shaft 23 when the parts are in the position shown in Fig. 5, a quick outward movement of the plunger first takes place and with an approximately uniform speed of rotation of the shaft the outward movement of the plunger and its attached parts becomes progressively less and less, and by the time the cone 6 begins to contact with the ferrule 10 of the core tube 9, the movement is small but the applied force is multiplied many times to produce a firm contact and insure the exact centering of the cone in the end of the tube core, so that its axis substantially corresponds with that of the core and the web roll.
Another feature resides in the fact that when the cone has been thus projected and in contact with the core tube as illustrated in Fig. 4, the operating link 20 is in such position that its longitudinal axis makes a very small angle with the axis of the plunger 4, or with the direction of its reciprocating movement. By reason of this small angle the various parts when in the positions shown in Fig. 4, or thereabouts, will be locked in such position, so that a rearward thrust from the cone 6 will not tend to move them. At such time, however, the pawl 30 would be in engagement with one of the teeth 35, which would further insure the axially fixed position of the cone 6 partially within and against the end of the tube 9.
What I claim is:
1'. In apparatus of the character described, a plunger, a rotatable cone member mounted thereon and adapted to support a web roll, a slide operable to move the plunger, a link pivoted at one end to said plunger and at the other end to the slide, and means for guiding and reciprocating said slide whereby the link is swung at a decreasing angle to the plunger axis toproject the cone member at decreasing speed, but with increasing force.
