  • the levers z" and 7*.” are actuated at the same time as the levers z' and 7.a, but are connected to the opposite end of the platen shaft, by reason of which the platen has an equal pressure on the type bed throughout its length. lf for any reason it is desired to operate the machine without reciprocating the platen, the dog (Z4 on the upwardly extending part of the levers t' and c" is raised out of the path of movement of the thumb screws a, allowing ⁇ the levers 7c and 71: to move freely on their pivots and j.
  • the adjusting screw n. provides a means whereby the looseness of the joints and the spring of the levers may be taken up and the platen held firmly when in contact with the bed.

  • A. feed roller F is mounted above the platen in slots IL10 in the hangers 71, and It and a. feed table T is attached to a cross bar of the frame in a proper position for the insertion of blank sheets of paper between the feed roller and the platen.
  • the feed roller has a reciprocating motion in the slots in the hangers toward and away from the platen, which is accomplished by mechanism hereinafter described, and during the time the roller is lifted away from the platen the paper is inserted therebetween and rests against the paper stops S2, S2 and as the feed roller F is brought into contact with the paper, the stops S2 are lifted out of the path of movement thereof allowing the paper to be fed forward due to the rotation of the platen and the roller.
  • a shield H is supported on the roller F by the hangers 7L and rests against the platen as shown in Figs. 2 and llt and a slight tension between the shield and the platen is produced by the spring s4 attached to the hollow cross bar b5 as shown.
  • the shield provides a means for properly placing ⁇ the paper on the type bed and the stops S2 provide a means of registering whereby the printing occupies the same position on all the printed sheets, the utility of which is in facilitating the insertion of names and dates, etc., by means of a typewriter, on such matter as circular letters.
  • the feed roller is raised from contact with the platen by the rock arm a5 and connecting bar 0G attached to the cam lever c, which is actuated by the cam C3.
  • the cam lever co is provided with a roller r3 against which the cam rides.
  • the rock arm a5 is attached to the rock shaft ai passing through the hollow cross bar b5 and, on the opposite end, the shaft a7 is provided with a rock arm as.
  • the rock arms t5 and as are positioned below the projecting ends of the feed roller F as shown in Fig. 3, thus providing means at each end of the feed roller for lifting it out of contact with the platen.
  • the stops S2 are actuated by the cam lever c6 by means of the connecting bar a2, rock arm @10, and rock shaft cl2.
  • the connecting bar a is slotted at the end to which the cam lever cG is attached, as said lever has a greater movement than is necessary to operate the stops, and, as is shown in Fig. 10, a spring s is mounted on the shaft C412 which tends to hold the stop S2 in position to stop the paper when inserted between the feed roller and the platen, and the cam lever only serves to raise the stops out of contact with the platen and allow the paper to be fed on to the bed.
  • the spring 37 which is attached turns the cam lever to its normal position after being acted upon by the cam C3, and during the latter part of the movement of the cam lever c, caused by the action of the spring sT, the stops are raised out of contact with the platen bythe slotted connecting bar a9.
  • the utility of the slot in the bar a is not only in allowing the lever c6 to move upward without interfering vwith the described action of the stops S2, but, on the return movement, allows the feed roller F to come in contact with the impression sheet (which has been inserted while the roller was raised) before the end of the lever c strikes the end of the slot and lifts the stops out of contact with the platen. If the movement of the feed roller F and the stops S2 were simultaneous, the sheet might become displaced before the roller was in place, but, by the arrangement above described, the stops remain in position until the roller comes in contact with the sheet thereby preventing a displacement of the sheet.
  • the feed roller F is grooved at f, f, to allow the stops S2 to be properly positioned in relation to the platen.
  • a ball clutch Q is provided at one end of t-he platen, loosely mounted on a collar g attached to the platen, as shown in Figs. 3 and 1l.
  • the balls g rest in pockets g2 in the member Q, the outer walls of which are eccentric to the shaft P and collar Q. If the member Q be rotated in the direction of the arrow shown in Fig. 1l, the balls Q bind between the eccentric walls and the collar and therefore rotate the platen.
  • the gear G on the opposite end of the shaft, is provided wi-th a clutch similar to the one above described.
  • the clutch Q is provided with a metal tape g3 0n its periphery which is connected to a lever g4 pivoted on the frame A.
  • the lever gt is connected to the cam lever Q by the connecting bar g5 and the cam lever is actuated by the roller r6 on the balance wheel W which roller r6 contacts the cam face Q3 of the lever Q once every revolution of the shaft C.
  • the roller to the rock arm a and the frame A, re-7 and balance wheel are shown in dotted lines in Fig. l and in full lines in Fig. 3.
  • the roller is so placed on the balance wheel that the cam lever Q is actuated and the platen rotated prior to the finish of the return stroke of the reciprocating bed and thus places the paper in the proper printing position before the platen is in contact with the bed.
  • the member Q is provided with a coiled spring Q6 that is placed under tension when the platen is rotated by the tape and returns said member Q, lever g4, and cam lever Q to their normal position after being acted upon by the cam roller r6.
  • One end of the spring is attached to the member Q and the opposite end is attached to the frame A.
  • the spring is shown in section in Fig. 3.
  • the cams C and C2 that bring the platen into contact with the type bed are timed to produce said contact slightly prior to the forward or printing stroke of t-he bed B.
  • the platen is then rotated by the rack 0l and the gear G in the same direction as iS produced by the clutch Q.
  • the clutch Q rotates the platen, which with -the coacting parts brings the end of the impression sheet to the printing position between the platen and the bed prior to the co-n-tact of the platen kwith the bed, and the rack Z and gear Gr rotate the platen during the printing movement of the bed.
  • the platen is in contact with the bed during said printing movement and the coaction therebetween continues the feeding of the impression sheet on to the bed.
  • the prin-ted sheet is grasped by the jaws J and J and, as the bed retreats, the paper falls into the pan or receiver U provided for such purpose.
  • the aw J is operated by rock shaft js, rock arm j?, connecting rod js, bell crank j", and rod jl attached to the lever lo as shown in Fig. 1.
  • the ribbon has a movement both longitudinal and crosswise of the bed, the utility of which is in maintaining uniformity of color in the ribbon. It is evident -that forms set up in the tray may not all be of uniform width and, if no provision was made for a crosswise movement of the ribbon, the central part thereof would become worn with those forms that were narrow and, when a wider form was used the resulting impression would be much heavier on the edges than in the central part. With a gradual shifting of the ribbon crosswise of the bed, this defect is eliminated as width.
  • the ribbon movement is produced by the pawls e, e', and e2 acting on the ratchets es, et, and e5.
  • the pawls are attached to the reciprocating bar E and are spring controlled as shown in Fig. 4.
  • the ratchets e3 and @5 are mounted on the shafts r one at each end of the type bed B and the ratchet e* is mounted on the shaft 0G near the center of the bed.
  • rl ⁇ he shafts r carry the ribbon spools S, S and have a keyway 102, shown in Figs. 5 and 7, in which the pin w3 engages when the spool is locked to the shaft.
  • rlhe pin is retained in position by the spring 'w'L attached to the end of the spool and said pin is bent as shown, and when the horizontal part is parallel with the shaft, it will drop into the notch L05 on the end piece of the spool and the lower end will enter the keyway @U2 and consequently lock the spool to the shaft.
  • the keyway w2 is of sutlicient length to allow the spool to be moved longitudinally on the shaft.
  • the pin w3 is raised out of the notch 105 and the bent end turned at right angles to the axis of the shaft. rPhe lower end is then out of the keyway and the shaft is free to revolve without rotating the spool.
  • the spring wt retains the pin in either position in which it may be placed.
  • An examination of Fig. 4L will show that a reciprocation of the bar E rotates both shafts 1 on which the spools S are mounted, consequently one of the spools must be free from the shaft in order that the ribbon may have a movement longitudinal of the bed B.
  • the free spool is locked to its shaft and the opposite one released from its shaft.
  • the bar E is carried by the reciprocating bed B and, as is shown in Figs. l; and 8, the actuating bar X is moved longitudinally of the bed, and, by means of the bent and notched end acting against the pin a2 in the bar E, moves said bar E longitudinally of the bed.
  • This movement of the bar places the spring rc under tension which returns the parts to their normal position when released by the forward movement of the bed.
  • the bar X is held on the bed by the screw in the slot fc3, and the bar X is also provided with a pin au* which, as the bed approaches the finish of the return stroke, strikes against the lug :e5 on the frame and as the bed continues its movement the bar X slides longitudinally of the bed and actuates the bar E as above described.
  • the movement of t-he ribbon crosswise of the bed is caused by the pawl e which intermittently rotates the ratchet e4 and shaft e6.
  • a barrel cam el is mounted on the shaft e and in the cam groove es a pin 'g/ rides.
  • the pin ,i/ is fastened in the lever Y as shown and the lever Y is provided with a forked end y2 adapted to encircle the end of the lever Y in which the pin is located.
  • the levers Y and Y are otherwise essentially alike.
  • the levers are attached to the type bed B at 3/3 and y'l as shown in Fig.
  • the latch is provided with a slot e in which is the screw e2 holding it in position on the bed.
  • a bent end of the latch is adapted to lift the pawl e out of engagement with the ratchet et when said latch is moved longitudinally of the bed.
  • a bent end e* provides a means whereby the latch may be moved and the screw e2 holds the latch in whatever position it may be placed.
  • the feed roller F is raised out of contact with the platen and the stops S2 brought into contact therewith prior to the printing movement of the bed B.
  • the blank paper is inserted between the feed roller and the platen and rests against the stops S2.
  • the cam lever Q is actuated which, in turn, actuates the clutch Q.
  • rlhe clutch Q rotates the platen and feed roller and feeds the paper forward during the latter part of the return movement of the bed.
  • the shield H guides the paper on to the bed between the platen and the bed, the platen being out of contact with the bed during the entire backward or return movement thereof.
  • the ribbon is moved forward by the slide bar X and coacting mechanism heretofore described.

MULTIPLE TYPE-WRITER PRESS.
To all whom it 'may concern:
Be it known that we, JOI-IN STAFFORD, a subject of the King of Great Britain, and Oris C. CURRIE, a citizen of the United States, both residing at Detroit, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Multiple Type-Trter Presses, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to multiple typewriter presses and its object is a device in which type set up in a flat bed or tray may be used to produce a result identical in appearance with that produced in a typewriting machine.
It is also an object of the invention to provide means whereby the ribbon, through which the impression is made, moves automatically across the face of the type both longitudinally and cross-wise thereof, there-` by maintaining uniformity of color throughout the entire ribbon.
Other objects and novelties of the invention, such as the means for registering whereby the printing occupies the same relative position on all printed sheets and the means for feeding the blank sheets on to the type bed, etc., are hereinafter more fully described and claimed.
In the drawings-Figure 1 is a side elevation of a machine embodying our invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is a section on line azz-0o of Fig. f2. Fig. 4l is a detail of the ribbon actuator. Fig. 5 is a plan view showing the means for producing a crosswise movement of the ribbcn during its `longitudinal movement across the face of the type. Fig. 6 is a detail of the means for clutching the ribbon spool to its shaft. Fig. 7 is a longitudinal section of Fig. 6. Fig. 8 is a detail of the means for operating the ribbon actuator.

showing the catch for releasing the lever that reciprocates the platen. Fig. 13 is a plan view of the jaw that removes the printed sheet from the type bed. Fig. 14 is a cross sectional view of the platen and the feed roll showing, in dotted lines, the position assumed by the parts when feeding paper on to the type bed.
Similar letters refer to similar parts throughout the drawings and specification.
A, A indicate the side frames which are supported by the cross Ybars a, a', etc., in ways fio in which side frames the type bed B is reciprocatingly mounted. The type bed, as shown in Figs. 2 and 3, is adapted to carry a tray g in which the type z' are set up.
The reciprocation of the bed is accomplished by means of the connecting rod r, one end of which is attached to the cam wheel C2 on the main shaft C, t-he opposite end being pivotally attached to a lever L which is keyed to the shaft a mounted in bearings in the frames A, A. The lever L is also keyed to the shaft a and to the free ends of the levers L and L are pivotally attached the connecting rods or bars o and o, the opposite ends of which are attached to lugs on the bed B. The rotation of the shaft C and cam wheel C2 consequently reciprocates the bed. Spools S and S are mounted on shafts 1^ at each end of the bed B and are adapted to carry the ribbon R across the face of the t-ype as hereinafter more fully described. As shown in Figs. 1 and 2, al platen P is reciprocatingly mounted above the type bed B. The type bed reciprocates in a horizontal plane and the platen reciprocates in a vertical plane and during the forward movement of the bed the platen is held in contact therewith and during the return movement of the bed is held out of contact therewith. The platen is also rotatable on the shaft P by means of the rack d, on the bed B, and the gear G loosely mounted on the collar Q2 attached to the platen. The teeth of the gear are of such length that they are never out of mesh with the rack during the reciprocating movement of the platen. Therefore, in order that the rack may not rotate the platen during the return movement of the bed, the gear G is not directly connected to the platen but is provided with a clutchl whereby said gear p rotates the platen during the forward movement of the bed and does not rotate the platen during the return movement of the bed, although the gear itself does rotate.
The shaft P, on which the platen is mounted, is supported by the hangers /L and it', one on each side of the machine, in a recess in the frames provided therefor. The lower end of each hanger L and It is pivotally connected to levers f/ and e" respectively, which are pivoted on the side frames at y' and j. Also pivoted at y' and j are the levers and 7c carrying the cam rollers m and m which ride on the cam wheels C and G2. Both the levers z' and 7c have upwardly extending ends 2 and 7a2 and a thumb screw n is threaded in the end 752 of the lever 7c and bears against the dog Zt pivoted on the end 2 of the lever z'. The levers z" and are also provided with upwardly extending ends and attached parts and have the same design and function as the levers i and 7c, consequently the description of one set of levers will do for both. The dog Z2 has a thumb piece Z5 by means of which it may be withdrawn from between the end of the thumb screw and the end 2 of the lever z' as shown in dotted lines in Fig. 12. The cam roller m on the lever rides on the cam C', as heretofore stated, and, by means of the thumb screw a, lever c', and the hanger it, intermittently brings the platen into contact with the type bed. The levers z" and 7*." are actuated at the same time as the levers z' and 7.a, but are connected to the opposite end of the platen shaft, by reason of which the platen has an equal pressure on the type bed throughout its length. lf for any reason it is desired to operate the machine without reciprocating the platen, the dog (Z4 on the upwardly extending part of the levers t' and c" is raised out of the path of movement of the thumb screws a, allowing` the levers 7c and 71: to move freely on their pivots and j. The adjusting screw n. provides a means whereby the looseness of the joints and the spring of the levers may be taken up and the platen held firmly when in contact with the bed.
In order to prevent the platen from being forced down between the lines of type by the pressure produced by the above described mechanism, and also to accurately gage the ink impression resulting therefrom, stops s, s, are provided against which the platen shaft P rests when in the printing position. Brackets B are bolted to each frame below the end of the shaft P and are provided with a recess in which the hangers /t and z. reciprocate. The stops s, which are simply cap screws, are located in tapped holes s2 in the brackets and cap screws s are inserted in the holes from the lower side forming a lock for the screws s. By adjusting the lock screws S and the stops a and thumb screws a heretofore mentioned, a greater or less pressure is produced between the platen and the bed. Springs s3 are mounted on the brackets and are adapted to hold the platen out of contact with the bed.
A. feed roller F is mounted above the platen in slots IL10 in the hangers 71, and It and a. feed table T is attached to a cross bar of the frame in a proper position for the insertion of blank sheets of paper between the feed roller and the platen. The feed roller has a reciprocating motion in the slots in the hangers toward and away from the platen, which is accomplished by mechanism hereinafter described, and during the time the roller is lifted away from the platen the paper is inserted therebetween and rests against the paper stops S2, S2 and as the feed roller F is brought into contact with the paper, the stops S2 are lifted out of the path of movement thereof allowing the paper to be fed forward due to the rotation of the platen and the roller. A shield H is supported on the roller F by the hangers 7L and rests against the platen as shown in Figs. 2 and llt and a slight tension between the shield and the platen is produced by the spring s4 attached to the hollow cross bar b5 as shown. The shield provides a means for properly placing` the paper on the type bed and the stops S2 provide a means of registering whereby the printing occupies the same position on all the printed sheets, the utility of which is in facilitating the insertion of names and dates, etc., by means of a typewriter, on such matter as circular letters. The feed roller is raised from contact with the platen by the rock arm a5 and connecting bar 0G attached to the cam lever c, which is actuated by the cam C3. The cam lever co is provided with a roller r3 against which the cam rides. The rock arm a5 is attached to the rock shaft ai passing through the hollow cross bar b5 and, on the opposite end, the shaft a7 is provided with a rock arm as. The rock arms t5 and as are positioned below the projecting ends of the feed roller F as shown in Fig. 3, thus providing means at each end of the feed roller for lifting it out of contact with the platen. The stops S2 are actuated by the cam lever c6 by means of the connecting bar a2, rock arm @10, and rock shaft cl2. The connecting bar a is slotted at the end to which the cam lever cG is attached, as said lever has a greater movement than is necessary to operate the stops, and, as is shown in Fig. 10, a spring s is mounted on the shaft C412 which tends to hold the stop S2 in position to stop the paper when inserted between the feed roller and the platen, and the cam lever only serves to raise the stops out of contact with the platen and allow the paper to be fed on to the bed. The spring 37, which is attached turns the cam lever to its normal position after being acted upon by the cam C3, and during the latter part of the movement of the cam lever c, caused by the action of the spring sT, the stops are raised out of contact with the platen bythe slotted connecting bar a9. `When the cam lever 0G is raised by the cam C3, the feed roller F is raised out vof contact with the platen by the vrock arms a5 and as as heretofore described and the 'stops S2 are brought into contact with the platen by the spring s6 on the shaft 0a12 shown in Fig. 10. In its normal position as shown in Fig. l, the cam lever c holds the stops S2 out of contact with the platen as the spring S7 is of sufficient strength to Overcome the action of the spring s which tends to hold the stops S2 in contact with the platen. The utility of the slot in the bar a is not only in allowing the lever c6 to move upward without interfering vwith the described action of the stops S2, but, on the return movement, allows the feed roller F to come in contact with the impression sheet (which has been inserted while the roller was raised) before the end of the lever c strikes the end of the slot and lifts the stops out of contact with the platen. If the movement of the feed roller F and the stops S2 were simultaneous, the sheet might become displaced before the roller was in place, but, by the arrangement above described, the stops remain in position until the roller comes in contact with the sheet thereby preventing a displacement of the sheet. The feed roller F is grooved at f, f, to allow the stops S2 to be properly positioned in relation to the platen.
It is evident that the paper must be inserted between the platen and the type bed prior to what may be termed the printing movement thereof and also before the platen is in contact with the bed. To accomplish this result, a ball clutch Q is provided at one end of t-he platen, loosely mounted on a collar g attached to the platen, as shown in Figs. 3 and 1l. The balls g rest in pockets g2 in the member Q, the outer walls of which are eccentric to the shaft P and collar Q. If the member Q be rotated in the direction of the arrow shown in Fig. 1l, the balls Q bind between the eccentric walls and the collar and therefore rotate the platen. The gear G, on the opposite end of the shaft, is provided wi-th a clutch similar to the one above described. The clutch Q is provided with a metal tape g3 0n its periphery which is connected to a lever g4 pivoted on the frame A. The lever gt is connected to the cam lever Q by the connecting bar g5 and the cam lever is actuated by the roller r6 on the balance wheel W which roller r6 contacts the cam face Q3 of the lever Q once every revolution of the shaft C. The roller to the rock arm a and the frame A, re-7 and balance wheel are shown in dotted lines in Fig. l and in full lines in Fig. 3. The roller is so placed on the balance wheel that the cam lever Q is actuated and the platen rotated prior to the finish of the return stroke of the reciprocating bed and thus places the paper in the proper printing position before the platen is in contact with the bed. The member Q is provided with a coiled spring Q6 that is placed under tension when the platen is rotated by the tape and returns said member Q, lever g4, and cam lever Q to their normal position after being acted upon by the cam roller r6. One end of the spring is attached to the member Q and the opposite end is attached to the frame A. The spring is shown in section in Fig. 3.
The cams C and C2 that bring the platen into contact with the type bed are timed to produce said contact slightly prior to the forward or printing stroke of t-he bed B. The platen is then rotated by the rack 0l and the gear G in the same direction as iS produced by the clutch Q. The clutch Q rotates the platen, which with -the coacting parts brings the end of the impression sheet to the printing position between the platen and the bed prior to the co-n-tact of the platen kwith the bed, and the rack Z and gear Gr rotate the platen during the printing movement of the bed. The platen is in contact with the bed during said printing movement and the coaction therebetween continues the feeding of the impression sheet on to the bed. At the finish of the printing stroke of the bed, the prin-ted sheet is grasped by the jaws J and J and, as the bed retreats, the paper falls into the pan or receiver U provided for such purpose. The aw J is operated by rock shaft js, rock arm j?, connecting rod js, bell crank j", and rod jl attached to the lever lo as shown in Fig. 1. It will thus be seen that, as the bed completes the forward stroke and the lever 7c releases the platen from contact with the bed and the paper thereon, the jaw grasps the paper, as shown in Fig. 2, and as the bed retreats the paper naturally falls into the receiver shown in dotted lines in Fig. 2.
As heretofore stated, the ribbon has a movement both longitudinal and crosswise of the bed, the utility of which is in maintaining uniformity of color in the ribbon. It is evident -that forms set up in the tray may not all be of uniform width and, if no provision was made for a crosswise movement of the ribbon, the central part thereof would become worn with those forms that were narrow and, when a wider form was used the resulting impression would be much heavier on the edges than in the central part. With a gradual shifting of the ribbon crosswise of the bed, this defect is eliminated as width. The ribbon movement is produced by the pawls e, e', and e2 acting on the ratchets es, et, and e5. The pawls are attached to the reciprocating bar E and are spring controlled as shown in Fig. 4. The ratchets e3 and @5 are mounted on the shafts r one at each end of the type bed B and the ratchet e* is mounted on the shaft 0G near the center of the bed. rl`he shafts r carry the ribbon spools S, S and have a keyway 102, shown in Figs. 5 and 7, in which the pin w3 engages when the spool is locked to the shaft. rlhe pin is retained in position by the spring 'w'L attached to the end of the spool and said pin is bent as shown, and when the horizontal part is parallel with the shaft, it will drop into the notch L05 on the end piece of the spool and the lower end will enter the keyway @U2 and consequently lock the spool to the shaft. The keyway w2 is of sutlicient length to allow the spool to be moved longitudinally on the shaft. To release the spool from the shaft, the pin w3 is raised out of the notch 105 and the bent end turned at right angles to the axis of the shaft. rPhe lower end is then out of the keyway and the shaft is free to revolve without rotating the spool. The spring wt retains the pin in either position in which it may be placed. An examination of Fig. 4L will show that a reciprocation of the bar E rotates both shafts 1 on which the spools S are mounted, consequently one of the spools must be free from the shaft in order that the ribbon may have a movement longitudinal of the bed B. To reverse the movement of the ribbon, the free spool is locked to its shaft and the opposite one released from its shaft.
The bar E is carried by the reciprocating bed B and, as is shown in Figs. l; and 8, the actuating bar X is moved longitudinally of the bed, and, by means of the bent and notched end acting against the pin a2 in the bar E, moves said bar E longitudinally of the bed. This movement of the bar places the spring rc under tension which returns the parts to their normal position when released by the forward movement of the bed. The bar X is held on the bed by the screw in the slot fc3, and the bar X is also provided with a pin au* which, as the bed approaches the finish of the return stroke, strikes against the lug :e5 on the frame and as the bed continues its movement the bar X slides longitudinally of the bed and actuates the bar E as above described.
The movement of t-he ribbon crosswise of the bed is caused by the pawl e which intermittently rotates the ratchet e4 and shaft e6. A barrel cam el is mounted on the shaft e and in the cam groove es a pin 'g/ rides. The pin ,i/ is fastened in the lever Y as shown and the lever Y is provided with a forked end y2 adapted to encircle the end of the lever Y in which the pin is located. The levers Y and Y are otherwise essentially alike. The levers are attached to the type bed B at 3/3 and y'l as shown in Fig. 2 and have forked ends g/5 and y that are adapted to ride in a groove e on the spools as shown in Fig. 5. It is therefore evident that a rotation of the barrel cam e7 will move the spools S, S lon gitudinally on their shafts r', thereby proA ducing a movement of the ribbon crosswise of the type bed. If the type form set up in the tray is as wide as the ribbon, it becomes unnecessary for the ribbon to have a movement crosswise of the bed and to stop said movement of the ribbon, the pawl e is raised out of engagement with the ratchet e* by means of a latch Z attached to the bed as shown in Fig. t. A bottom view of the latch is also shown in Fig. 9. The latch is provided with a slot e in which is the screw e2 holding it in position on the bed. A bent end of the latch is adapted to lift the pawl e out of engagement with the ratchet et when said latch is moved longitudinally of the bed. A bent end e* provides a means whereby the latch may be moved and the screw e2 holds the latch in whatever position it may be placed.
In operation, the feed roller F is raised out of contact with the platen and the stops S2 brought into contact therewith prior to the printing movement of the bed B. During this interval the blank paper is inserted between the feed roller and the platen and rests against the stops S2. As the feed roller is again brought into contact with the platen, the stops are raised out of contact therewith and the cam lever Q is actuated which, in turn, actuates the clutch Q. rlhe clutch Q rotates the platen and feed roller and feeds the paper forward during the latter part of the return movement of the bed. The shield H guides the paper on to the bed between the platen and the bed, the platen being out of contact with the bed during the entire backward or return movement thereof. At the finish of the return stroke, the ribbon is moved forward by the slide bar X and coacting mechanism heretofore described. As the type bed is about to start on its forward or printing stroke, the cams C', C2 bring the platen into printing contact with the bed by means of the cam rollers m, m and connected levers. During this forward stroke of the bed the platen is ro tated by means of the rack and gear heretofore described in detail. rJhe rotation of the platen continues to feed the paper on to the bed and, as the bed reaches the limit of its forward movement, the platen is released from its contact with the bed and the jaws J and J grasp the printed sheet of paper by reason of the cam rollers dropping on to the lower part of the cams C and The springs S3 hold the cam rollers in contact with the cams. rlhe jaw el is stationary,
being mounted on the inner ends of the tubes T2, T3 as shown in Fig. 13. The tubes are mounted in brackets Z915 on the side frames, as shown in Figs. 1 and 13. The jaw J is mounted on the rock shaft je which is located in the tubes as shown. As the bed begins its return movement, it retreats from under the paper, allowing it to drop into the receiver U when released by the aw at the nish of the stroke.
