Definitions
- a device for retaining a tubular member on a support member disposed interiorly of the tubular member.
- the device includes at least one pivotal arm for engaging an end of the tubular member to hold it in place.
- the arm is pivotal to a retracted position upon movement of a reciprocally movable knob, thereby enabling the tubular member to be removed axially over the retaining device.
- This invention relates-generally to devices for retaining a tubular member on a supportmemberdisposed'interiorly of the 1 tubular member. More particularly, the-invention relates to such a device which is useful'for retaining a paper supply roll teriorly of the tubular' member.
- a sheetlilte material must be dispensed
- rolls of such material may be wound on a tubular member supported-for rotation to dispense the sheetmaterial.
- a particular example of such apparatus is in electrostatic printing equipment, wherein a roll of electrostatic printing paper is mounted on a holder and is rotated'periodicall y tofeed paper int o other parts of the apparatus as'required;
- the person reloading the machine typically has to detach the holding device, set down the device, remove the old tubular member, replace it with a new rol-h pick up'the holding device and finally reattach it. Thispresents a degree of inconvenience in the use of equipment ofthis type.
- Another object of the invention is to provide an improved device for holding, in alignment, continuous rolls of sheetIike material on a support member.
- a further object of the invention is to provide a rollretaining device which holds the rolls firmly-in alignment andwhich enables removal and replacement'of the rolls without the necessity of detaching the device'from the remainder of the equipment.
- FIG. 1 is a full section view-of-a device constructed in accordance with the invention
- FIG. 2 is a full section'view ofthe'device of FIG; 1 showing an-alternate position
- FIG. 3 is anexploded'perspective-view'of-a portion of'an'altemative embodiment of the invention. 7
- the device illustrated therein is for use in connection with electrostatic printing equipment;
- a continuous roll 18 of electrostatic printing paper is wound upon the tubular-member 11'.
- the support member 12 is disposed interiorly ofthe tubular'member 11 and includes-a pair or rollers or hubs 192 only one; of which is shown, joined together by a metal tube 21.
- The'me'tal tube 2 is joined-to 'the'rollers l9 at annularshoulders 22 providedin the rollers-at theinnermost facingedges-thereof.
- the rollers are-each provided-with apair'o'f' chamfered surfaces 13and'24 2 and a mating surface 26 which forms the outermost or largest diameter portion of the rollers.
- the surface 26 is of a'diameter which accommodates the cardboard tube ll, with a fit of a closeness which enables the tube to slip onth e rollers if sufficient torque is exerted. The reason for this'is' explained below.
- Each of the rollers is provided'with a threaded hole 27 therein which extends downwardly 71o"anaxial opening 28'.
- the axial openings 28 extend'axi'ally through'the respective rollers 19.
- a setscrew 29 is provided in each of the openings 27,'ionly one setscrew being shown-,and is tightened against a roller or hub shaft 31.
- the shaft 31- extends through the opening 28in the rollers or hubs 19.
- the shaft 31 is suitably journaled and cantilevered at the end not shown within the electrostatic printing equipment.
- the shaft 31 is provided with an axial opening32 therein near one end of the shaft.
- the stub shaft 13 has a region of enlarged diameter which fits within and mates within the opening 32.
- a pair of flats 33 are provided toward the interiormost end of the stub shaft 13.
- a threaded hole 34 is provided in the shaft31 opposite each of the flats 33, and a setscrew 36' is 'p'rovidedin each of the holes 34 to be tightened against the" flats 33 and thus cause the shaft 31 to lock to and be rotatable with the shaft 13.
- the shaft 13 and the shaft 31 may be made in a single piece. I
- a suitable guide or flange is provided against which the end of the hollow tube 11 may abut. This flange aids in aligningthe paper roll 18 relative to the rest of the equipment.
- the device of the illustrated invention provides twoarms 16 The arms 16 exert a pressure, as willbeexplained subsequently, against the end of the tubular member 11 "and thus force" it H against the unillustrated flange or guide for proper alignment.
- Each of the arms 16 is mounted in a corresponding one of a pair of recesses 41 provided in the knob 14 at positions 180 apart.
- the arms 16 are mounted to the knob l4'by a pair of pivot-type shoulder screws 43, respectively, which extend across the recesses 41.
- the knob 14 contains a central opening 44' in which the projecting portion of the shaft 13 is accommodated.
- the diameter of the opening 44 is such with respect to the shaft 13 as to permitthe knob 14 to be reciprocated axially on the shaft.
- the shaft 13 is provided with a bore 46 which passes diametrically through the shaft at a region near the pivot points of the arms 16.
- a sleeve 47 is force fitted within the bore 46 and projects radially from the shaft 13 at each end of the bore.
- the resilient means 17 include a compression spring 49 within and coaxial with the sleeve 47; A pin 51exten'ds transversely of each recess 48 in each arm 16 andv bears against the corresponding end of the compression spring 491 Slots 5 3,'in diametrically aligned pairs, are provided at each end of the sleeve 47; The slots extend axially of the sleeve at least as far as the outer diameter of the shaft 13 for reasons which will be explained subsequently.
- the bias exerted against the pins 51 by the compression springs 49 produces a moment about the shoulder screws 43, indicated by the arrows, to cause the arms 16 to press against the end of the tubular member 11. This force holds the paper roll in place and properly aligned.
- the arms 16 may be moved into a position alongside the stub shaft 13 so they will be within the periphery of the interior of the tubular member 11 when the tubular member is removed from the support member 12.
- the knob l4 is pulled to the left in the drawings. The movement of the knob is from the position shown in FIG. 1 to the position shown in FIG. 2. Force exerted on the knob while it is being pulled outwardly overcomes the moment produced by the compression spring about the shoulder screws 43 and, because the pins 51 are confined in the slots 53, the arms pivot about their pivot screws. This pivoting continues until the arms reach the position shown in FIG. 2.
- FIG. 3 In the exploded perspective view of FIG. 3, an alternative embodiment of the invention is shown.
- the embodiment of FIG. 3 affords an alternate way of attaching the shaft of the retaining device to the shaft 31 of the support member.
- the shaft 61 (corresponding to the end of shaft 13 extending into opening 32 as seen in F 1 and 2) is provided with a coaxial opening 62 therein and a plurality of radial slots 63 passing from the opening 62 to the outer surface of the shaft 61.
- the slots extend axially along the shaft 61 a distance sufficient to make the slotted end of the shaft expansible.
- the small end of a tapered plug 64 is loosely inserted into opening 62.
- the invention provides an improved device for retaining a tubular member on a support member disposed interiorly of the tubular member.
- the device affords a distinct advantage in that alignment of the tubular member, such as may be used for supporting continuous sheet material rolls, is effected in a positive way, and yet the device is operable to enable removal of the tubular member without separation of the device from the remainder of the apparatus. This reduces the possibility that the device may become misplaced when rolls of paper are being replaced, and simplifies installation procedures as well.
- a device for retaining a tubular member on a support member disposed interiorly of the tubular member comprising, a shaft of smaller cross section than the interior of thetubular member, said shaft being adapted to extend axiallyfrom an end of thesupport member, a knob of smaller cross section than the interior of the tubular member, said knob being mounted on said shaft and being selectively manually movable axially along said shaft between a first and a second position with respect thereto, two arms pivotally mounted to said knob and being pivotal on parallel axes between a first position alongside said shaft and generally parallel thereto and a second position engaging an end of the tubular member and generally perpendicular to said shaft to retain the tubular member on the support member, and resilient means comprising a compression spring supported coaxially within a hollow sleeve extending transversely through an opening in said shaft, said resilient means acting on said arm at a point displaced from the pivot point of said arm at each of said first and second positions of said knob to provide an overcenter toggle action upon axial
