  • Fig. 10 is a like view including additional parts and showing the parts disposed in an intermediate position between those positions which are indicated in Figs. 8 and 9.
  • the present invention was devised-to attain some of the same general ends as the construction disclosed in the patent to Frederick A. Hart, 1,650,351, dated Nov. 22, 1927, and may be regarded as an improvement thereon.
  • the frame of the machine includes a top plate 1 on which fixed carriage rails 2 and 3 are-supported by brackets 4 in the usual manner. Said rails are provided with oppositely grooved race:- ways to receive crossed bearing rollers 5 which also are received in race-ways in a cross bar6 of the carriage. In this manner the carriage is supported'at the rear thereof for traveling movement from side to side of the machine over the top plate 1.
  • the carriage includes end bars 7 and 8 which are secured to and project forward from the rear cross bar' 6 and have bearing openings therein for the platen shaft 9 by which a cylindrical platen 10 is supported.
  • the usual line spacing mechanism and finger wheels (not shown) are employed for turning the platen. I
  • a paper table 11 is supported in the rear of the platen to aid in directing forwardly introduced work sheets to the rear of and beneath theplaten.
  • Upwardly and rearwardiy moving typebars strike against the front of the platen of the paper thereon.
  • a line a in the different figures represents the printing line or a line with register.
  • the type bars in moving to printing position coact with a type bar center guide 16 'of to brackets 21 provided with set screws 22 by which the deflector may be fixedly connected to a rock shaft 23.
  • a rocking of this shaft is effective to move the deflector from the Fig. 1 to the Fig. 2 position and vice versa.
  • the rock shaft 23 carries a crank arm 24 at one end thereof which is fixedly connected to the shaft by a set screw 25, thus enabling the crank arm to be secured in different v adjusted positions to the shaft.
  • a forwardly projec'ting link 26 is pivoted at its rear end, as at 27, to the crank arm 24 in order to automatically effect a movement of the deflector down from the Fig. 1 to the Fig. 2 position and up again, as will hereinafter more clearly appear.
  • I provide a plurality of flexible or resilient work sheet supporting and guiding bands 28, two being shown in the present instance. These bands are provided to cooperate with the platen 10 to aid in supporting, guiding and feeding one of the work sheets, L, to and around the platen as such work sheet is introduced from the rear thereof.
  • Each of these bands 28 is secured at its upper rear end by bolts 29 and nuts 30 to the upper horizontally disposed portion of the paper table 11.
  • the bands 28 extend from the attached ends thereof parallel with the paper table 11 and around and concentric with the platen and up in front of and above the platen where the free ends of the bandsbear against a cross bar 31 fixed to the carriage and extending from side-to-side thereof above the platen.
  • These bands are slightly resilient and bear against the platen with suflicient force to snugly maintain a work sheet L which is introduced into the ma- .chine from the rear of the platen andbetween said bands and platen, in contact with the platen and cause the sheet to be effectively fed therewith when the platen is rotated.
  • the cross bar 31 is secured to the carriage by bracket arms 32 carried thereby, said bracket arms being secured by set screws 33 to a cross rod 34 attached at its ends to the end plates 7 and 8 of the'carriage.
  • the cross bar 31 also constitutes a support for a second paper table 35, the front face of which is maintained substantially tangential to the platen at the front portion thereof.
  • This paper table constitutes'a support for a work sheet B that is introduced into the machine from in front of the platen and is directed downwardly and rearwardly beneath the platen to the deflector 20, as indicated in Figs. 1 and 2.
  • a second deflector plate 37 that is automatically moved from the ineffective position shown in Fig. 1, to the effective position shown in Fig. 2, where the lower end of the deflector 3'7 is moved into cooperative relation with the deflector 20 to practically form a continuation thereof for directing the lower end of the work sheet B into the machine past the type guide and ribbon vibrawhich the bottom ends of the printed characters torand into the channel 38 between the deflector 20 and the platen.
  • This movement of the deflector 3'? to and from effective position it moves past the printing line and must necessarily be moved from its effective position, shown in Fig. 2, to the ineffective position shown in Fig. 1, before the type bars can reach the printing position.
  • This operation of the deflector 37 is automatically controlled, as will hereinafter more clearly appear.
  • a carbon sheet C preferably substantially coextensive with the work sheet L is simultaneously introduced into the machine therewith and is employed for making a manifold copy of the work written onthe work sheet B.
  • a carbon sheet coextensive in size with the bill sheet B may be introduced and withdrawn with the latter instead of employing the carbon sheet C in the manner indicated.
  • a line indicator which is in the nature of a thin flat sheet metal strip 39 that extends longitudinally throughout the length of the platen and is connected at its ends to depending portions 40 of two arms 41 and 42. These arms at their forward ends are secured by set screws 43 to a rock shaft 44 that extends across the carriage from side-to-side thereof and is supported in bracket arms 45 fixed to the carriage.
  • the line indicator 39 receives a direct up and down motion to and from indicating position around the center of the shaft 44, the line indicator being shown in its indicating position in register with the printing line a in Fig. 8, and in the lowered, ineffective, position in Fig. 7.
  • Means are provided for automatically controlling the line indicator 39, as will hereinafter more clearly appear.
  • Each arm 48 carries a pin 50 by which one end of a coiled spring 51 is connected to the companion arm 48, the opposite end of said spring being anchored to a collar 52 secured by a set screw 52 to the rock shaft 53.
  • Each hub 49 is slabbed off at one side thereof, as indicated at 54, to provide a contact face for cooperation with a corresponding slabb'ed ofi portion or contact face 55 of a collar 56 secured by set screws 57 to the rock shaft 53. There is a slight lost motion provided between the contact face 55 of each collar 56 and the contact face 54 of the associated hub 49 with which it coacts.
  • each arm 48 is provided with an individual spring 51 which exerts its individual force on the companion arm 48, as will presently appear, and that the effective force of each of said springs may be varied by a rotative adjustment of the companion collar 52 to different set positions around the shaft 53.
  • both arms 48 and the springs 51 will turn bodily therewith, and but a slight spring pressure is exerted by each of the springs 51.
  • Fig. 3 represents the positions of the parts when the feed rollers 46 have been brought to bear against the work sheets without tensioning the springs 51. At this time the feed rollers bear against said work sheets wholly by the weight of the parts, free from any pressure of the springs 51. This is in order that the ledger or bill sheet, and more particularly the latter, may be adjusted relatively to the line indicator while the sheet is held by thefeed rollers 46 in its position of adjustment, but without suflicient pressure to interfere with the adjustment of the sheet.
  • the rock shaft 53 is given a further rocking motion to tension the springs 51 and effectively apply a feeding pressure to the feed rolls 46.
  • Means are provided for locking the rock shaft at the end of this movement by which the springs are tensioned, in order to prevent a return of the rock shaft under the reaction of said springs.
  • Such locking means and the means for controlling the rock shaft 53, as well as other of the devices previously described, will now be referred to.
  • the rock shaft 53 constitutes the main actuating shaft by which the various devices of my invention, including the feed rollers 46, the bottom deflector 20, the'line indicator 39 and the front deflector 37, are controlled.
  • This shaft 53 is mounted at its ends in bracket plates 58 and 59 secured to the carriage frame, and near the right-hand end thereof said shaft is provided with a crank arm 60 that terminates in a finger piece 61 by which the shaft may be actuated.
  • Fivoted at 62 on the outer side of the arm 60 is an angular or bell crank lever 63 provided at the end of one of its arms with a finger piece 64, as best shown in Figs. 2 and 3.
  • the other arm 63" of the lever 63 has a locking pawlor latch 65 pivoted thereto at 66, said latch having a hooklike engaging end 67.
  • Extending laterally from. the member 65 are two lugs or stops 68 and 69 that are on opposite sides of and coact with the arm 63' to limit the motion of the latch relatively to said arm.
  • a leaf spring 70 is fixed at one end by screws 71 to the lever 63 and bears at its free end against the lug 69 to normally maintain the latch member related to the arm 63 as shown in Fig. 2.
  • a coiled spring 72 surrounds the pivot 62 by whichthe lever 63 is mounted on the crank arm 60, the other end of said spring being fixed to the lever 63, as indi-' 'cated at '75.
  • the force of this spring is therefore relative movement of the lever 63 is limited by a pin 74 carried by the arm 60 passing into a slot 76 in said lever 63.
  • the finger piece 61 In addition to controlling the feed rollers in the manner described, the finger piece 61 also controls the movement of the bottom deflector 20 from the Fig. 1 to the Fig. 2 position and vice versa. Such means will now be described.
  • the link 26 (see Fig. 3) is a two part link, the members of which are united by a thread.- ed connection at 78 and the front member is slotted at 79 to receive the shank of a headed screw or pin 80 received at its threaded end in a tapped opening in a disk 81.
  • This disk has a hub 82 (see Fig. 6) tapped .to receive a set screw 83 by which the disk is secured to the rock shaft 53. Due to the pin and slot connection-80, 79 between the link 26 and the shaft 53, the deflector 20 will remain unaffected by the turning of the shaft 53 until just prior to the time that the arm 60, in swinging forward, reaches the Fig. 10 position.
  • the pin 80 When such position has been reached, the pin 80 has reached the forward end of the slot 79 and has shifted the link 26 forward and moved the deflector 20 down away from the platen in order to create an enlarged, unobstructed, channel 38 between said deflector and the platen for the free passage of a rearwardly introduced work sheet B, and an accompanying carbon sheet if such be used instead of the carbon sheet C.
  • the bands 28 hold the previously introduced ledger sheet L snug against the platen so that it offers no obstruction or obstacle to the ready backward introduction of the bill sheet B into position in the manner described.
  • the pin 80 will be carried rearward enabling a spring 84 (Figs. 6 and 10) to elevate the.d eflector 20 to a position where it will bear lightly against the sheet B and press it lightly against the under sides of the metallic bands 28.
  • the spring 84 surrounds the rock shaft 23 and is connected at one end to one of the brackets 21 and is connected at the other end to a fixed part 85 (see Figs. 1 and 10) of the carriage.
  • the rock shaft 53 also controls the movement of the line indicator 39 to and from effective, or indicating position, as will now be pointed out.
  • one of the supporting arms, 41, for the line indicator 39 has one end of acontractile returning spring 86 connected thereto, at 87.
  • the other end of this spring is connected to a pin 88 that projects from one side of the adjacent bracket plate 58.
  • the force of this spring is exerted to move the arms 41 and 42 upward and bring the indicator 39 to the line indicating position, as shown in Figs. 3 and 8.
  • the parts are arrested in their movement to such position by an adjustable screw stop 89 threaded into a fixed part of the carriage or bracket plate 58 and cooperating at its lower end with the arm 42, as shown in Fig. 8.
  • the arm 42 carries an upwardly extending finger 90 and extends into the path of a cam 91 formed as a depending part of the crank arm 60.
  • the cam 91 will be brought into engagement with the upper side of the arm 42, and the finger 90 which is formed thereon, to depress the line indicator 39 to the ineifective Fig. 10 position, and hold it in such position.
  • the curved contact faces 92 on the cam reaches and coacts with the arm 42 and acts in the nature of a dwell to hold the indicator in its lowered position during the further forward motion of the arm 60.
  • Such forward movement of the arm 60 is limited by a stop pin 93 on the hub 94 of the arm 60 coacting with a pin 95 projecting from the righthand bracket plate 59, as shown in Fig. 9.
  • the body portion of'thearrn 60 also is operative on the extreme end of the finger 90 of the arm 42 when said arm is moved backward and downward from the Fig. 8 to the Fig. '7 position, and at this time moves the indicator 39 from the indicating to the ineffective position out of the path of' the types.
  • This motion of the arm 60 takes place as said arm is moving from the Fig. 3 to the Fig. 1 position, to tension the springs 51 and apply the force thereof to the feed rollers 46, as hereinbefore described.
  • said springs 51 will be looked under tension and the line indicator will be held depressed until the latch 65 is released in the manner hereinbefore pointed out.
  • the upper edge of the deflector 37 is bent around and secured to a shaft 96 supported at its ends for pivotal move ment in bearings 97 in supporting arms 98 secured to a rock shaft 99.
