Definitions

  • This invention relates to' improvements in cash registers and similar machines, and more particularly to improvements in ribbon feeding and reversing mechanisms for such machines.
  • the invention is illustrated in connection with, and is adapted to be used with machines of the type illustrated and described in applications for Letters Patent of the United States, Serial Numbers 261,996 and 3%,077, filed March 15, 1928 and March 2, 1929, respectively, by Bernis M. Shipley.
  • Another object is to provide a machine of the type indicated, with a novel control for a ribbon reversing mechanism.
  • Still another object is to provide in a machine of the type indicated, a ribbon reversing mechanism having a. novel means to insure complete operation of the controlling element.
  • the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this specification.
  • Fig. 1 is a view in left elevation of one convenient form of ribbon feeding and reversing mechanism embodying this invention.
  • Fig. 2 is a detail sectional view taken through one of the ribbon spools.
  • Fig. 3 is a sectional view taken on lines 33, Fig. 2, through the ribbon spool, look ing in the direction of the arrows.
  • the machine chosen to illustrate the present invention is of the press-down or keyoperated type, and is equipped'with a plurality of groups of keys, depression of any single key of any of which groups operates the well-known key coupler through which several functions of the machine are effected.
  • the ribbon frame is readily placed in and V 1929. Serial No. 344,362.
  • the ink ribbon (Fig. 1) through which the impression platen (not shown) takes impressions from the set of type elements (also not shown), is alternately wound on and unwound from two ribbon spools 31 and 32, rotatively mounted at the opposite ends of a self-contained ribbon frame or unit removably supported in the machine above the type elements.
  • This ribbon frame includes similarly shaped sides 33 and 34 joined by cross pins 35 and 36, projecting from the side 33, and telescoped within the inner ends of tubes 38 supported on studs 39, only one of which is shown, ig. 2), projecting from the side 34:.
  • a cross rod 40 also projecting from the side 34 extends between the two sides and through a hole in the side 33, the outer protruding end of the cross rod having an annular groove formed thereon, adapted to be engaged by a retaining clip 41 pivoted at 42 to the outer face of the side 33 to hold the sides 33 and 34 together.
  • the cross pins 35, 36 and the cross rod 40 also serve to guide the ribbon 30 as it is fed at each operation of the machine.
  • the ribbon spools are each supported in like manner at the respective ends of the ribbon frame, and only the spool 32, which appears in section in Fig. 2, need be described.
  • the spools each comprise a tube, from the opposite ends of which project lugs 49 which pass throughperforations formed through apertured disks 52 and 53 respectively, the ends of the lugs being bent outwardly radially of the disks to secure the latter snugly against the ends of the tube 32, to form a spool, the bore of the tube lying in line with the apertures in the disks.
  • the spool is rotatably supported at one end on a trunnion 54 projecting inwardly from the side 33 of the ribbon frame, and at its 0pposite end on an elongated thimble or bushing 55 journaled on a stud 56 secured to and projecting inwardly from the complementary side 34 of the ribbon frame.
  • the trunnion 54 is journaled in the side 33 through which it projects, the. longer inner end of the trunnion extending through the aperture in the adjacent end disk 52 and into the bore of the tube 32.
  • the diameter of the trunnion 54 is just sufficient to enable it to pass through the aperture in the disk 52, which aperture, as well as that in the disk 53, is of less diameter than and is concentric with the bore of the tube 32, so that the spool is supported at its opposite ends by the edges of the disks 52, 53.
  • the aperture in the disk 53 encircles the thimble 55, the open end of which is outwardly flanged, as at 47, and accommodates the stud 56.
  • the stud 56 is provided with a reduced extension 46 passing through a hole formed in the inner closed end of the thimble, the reduced end acting as a guide for the thimble.
  • a spring 57 encircling the reduced end 46 of the stud 56 and hearing at its opposite ends against the closed end of the thimble and the shoulder formed by reducing the end of the stud 56, serves to advance the tliimble to the left (in Fig. 2), which latter, by its flange 47, forces the spool towards the'left (Fig.
  • Ratchet wheels 60 and 61 are secured to the outer ends of the respective trunnions of each spool 54 to rotate the spools 31 and 32, thereby winding the ribbon on one spool, and unwinding it from the remaining spool.
  • a bell crank 62 (Fig. 1) journaled on a rod 63, supported in the frame 51 of the machine, and adapted to be rocked first counter-clockwise and then clockwise at each operation of the machine, carries feed pawls and 71, pivoted on arms 72 and 73, respectively, of the bell crank.
  • Springs 74 and 75 rock their respective feed pawls 7 O and 71 into co-operative relation with their corresponding ratchets 60 and 61.
  • the stud 78 on the feed pawl 70 rides on the arcuate edge of the particular disabling lobe 76 of the control disk 77 to prevent engagement of the feed pawl with its ratchet 60.
  • the force of gravity acting upon the key coupler 82 restores the key 83 to its undepressed position and rocks the bell crank 62 clockwise to its normal position, which restores the feed pawls 70 and 71 to their normal positions.
  • Ribbon feed renaming mechanism Obviously, if the control disk 77 is advanced one step, it will shift the active lobe 76 away from the stud 78, for example, to enable the spring 74 to rock its feed pawl 70 to effective position relatively to its corresponding ratchet 60, and by the same movement, will introduce another lobe 76 beneath the stud 79 of the active feed pawl 71 to rock the la ter to idle position against the tension of its spring 75.
  • control disk 7 7 remains where set'until the ribbon is practically fed off of one spool and onto the other, at which time, means is provided to automatically advance the control disk one step to reverse the direction of feed of the ribbon.
  • a spring 93 connected to the pawl 94 operates to impose a continuous draft on the pawl tending to rotate the ratchet 98 and control disk, 77 counter-clockwise, but such advance of the control disk is normally prevented by restraining means under control of the ribbon, as now explained.
  • the periphery of the disk 52 is recessed, as shown at 90, (Fig. 3), the recess being normally closed and the circumference of the disk 52 filled in by an annulus 91, pivoted at 59 on the disks 52 and 58.
  • the stud 59- is riveted to the annulus 91 and enters openings in the disks 52 and 28 as hereinbefore described.
  • the annulus surrounds the tube forming the body of the spool 32, the inner perimeter of the annulus having a lip 92 struck laterally therefrom to lie within an aperture 89 formed in the tube, though this aperture is not essential to the operation ofthe parts.
  • a roller 102 mounted on the offset free end of the elbow lever 100 is forced into contact with the peripheries of the disk 52 and its auxiliary annulus 91, and so long as there is suflicient ribbon on the spool to confine the lip against the tube of the spool, so as to maintain the annulus in position to prevent entry of the roller 102 into the recess 90 in the disk 52, the elbow lever is prevented from rocking, and hence its stud 99 in contact with one of the lobes 76 of the control disk effectually holds the control disk 77 against rotation by the spring 93 and pawl 94.
  • Rotation of the control disk 77 is now restrained by the engagement of the inclined edge of one of the lobes 76 with a stud 110 on an arm 111 pivoted at A roller 113 on the arm 111 rests against the peripheries of the disk 52 and collapsible annulus 91 of the spool 31, which latter holds the arm 111 against movement, thereby preventing another advance of the control disk "7 until the ribbon 30 is nearly all unwound from the spool 81, whereupon the collapsible annulus 91 (not shown) on this spool, yields to permit the arm 111 to carry stud 110 out of the path of the lobe 76, thus freeing the spring 93 to operate the reversing pawl 94: and turn the control disk 7 7 one step to disengage the feed awl from its ratchet 60, and reengage the feed pawl 71 with its ratchet 61.
  • control disk 77 Since the control disk 77 is spring-actuated, it is conceivable that some peculiar condition might arise to prevent the full step of movement of the control disk. This could result either in holding both the feed pawls 7 0 and 71 clear of their respective ratchets 60 and 61, or in permitting both feed pawls to engage their ratchets at the same time. Also, in a case of this nature, the reversing ratchet 98 would not be sufficiently advanced, and the reversing pawl 94, when retracted, would fail to engage the next ratchet tooth.
  • a spring-pressed dog 115 pivoted on an arm 116 projecting from the feed pawl-carrying bell crank 62 is given an invariable movement at each operation of the machine, first in counterclockwise direction, and then clockwise to normal.
  • the spring 93 fails to advance the control disk 77 its full step of movement the dog 115 on the first operation of the machine following the collapse of one of the collapsible annuli, picks up the reversing ratchet 98 and advances it and the control disk 77 the proper distance.
  • WVhat is claimed as new, is:
  • the combination with a plurality of ribbon spools spaced apart from each other; of feed pawls normally adapted to drive the respective spools; a single bell crank located intermediate the spools, one of the feed pawls being mounted on each arm of the bell crank and operated thereby; and means co-axial with the bell crank to render ineffective one or another of the pawls.
