My invention relates to typewriting and like machines and more particularly to means for automatically controlling paper feed rollers and other devices in such machines.

The main object of my invention, generally stated, is to provide simple and eficient means of the character stated. I

A further object of my. invention is-to provide means by which an automatic release of the feed rollers, or certain only of them,

may be variously brought about, depending matically operate in harmony and in timed relationship.

I have shown my invention, in the present instance, embodied in a machine known on the market as a Remington front feed machine, such as is disolosed, for example, in the application of Frederick A. Hart and Siguard L. Walsoe dated Sept. 23, 1927,

Serial No. 221,543, in which the features of the present invention may be readily incorporated without modifying, or materially modifying the existing structural features of, said machine. It should be understood, howfragmentary, enlarged, detail,

ever, that the devices of the present invention are not restricted to use in said machine,

but may be embodied in typewriting and like machines generally, wherever found avail- 5 able.

I will first describe generally the Remington front feed machine substantially as it is disclosed in said above mentioned application, and will then describe how the devices of my present invention are brought into cooperation therewith to automatically control the operation of the parts instead of effecting a hand control thereof, as the machine is at present constituted.

The machine in question is provided with means to aid in rapidly correlating two or more work sheets in the machine ready to receive the typed impressions thereon, one d1- rectly from the printing instrumentahties others, as manifold copies produced through interposed carbon sheets. The machine s used in different ways and for the attainment of different specific ends in billing, pay roll and check writing, etc., but for the purposes of the present invention, and by way of illustration, it may be assumed that an outside bill or statement sheet B is employed. Next to this is a carbon sheet C and between said carbon sheet and the platen l is a ledger sheet L to receive manifold copies of entries, or certain of the entries, made on the bill sheet.

A ledger sheet L is first introduced into the machine from the rear of the platen and is guided to and up in front of the platen 1 and across the printing line by a curved deflector 2 and between said deflector and the platen. A line indicator 3 is automatically moved towards and away from the platen and aids the operator in properly positioning the ledger and bill sheets. Marginal paper feed rollers 4 are mounted in the usual manner, to be hereinafter more clearly indicated, for movement to and away from the platen. When the ledger sheet L is properly positioned with the additional aid of side guides (not shown), the marginal feed rollers 4 are applied to the marginal portions of the ledger sheet and hold it clamped against the platen. The operator then moves the finger piece 5 forward and this results in moving the line indicator 3 forward away from the platen and in moving a forward paper deflector 6 rearward and downward until the lower edge thereof overlaps the forward end 7 of a second curved deflector 8 arranged beneath the platen and maintained spaced apart from the deflector 2, providing an open space or channel 9 between the two. At the same time the ribbon vibrator 9 is automatically lowered in the usual manner to carry it out of the path of movement of the deflector 6 to effective position. The move- 05 ment of the line indicator 3 out of the way through the inking ribbon and the other, or

and the positioning of the deflector 6 in the position indicated facilitates a rearward in troduction of bill sheet B and accompanying carbon G into the channel 9 between the two deflectors 2 and 8. When the sheets B and C are thus introduced the operator releases the finger key 5 and enables the line indicator 3, deflector 6 and the ribbon vibrator to return to the normal position, shown in Fig. 6. The operator then adjusts the sheets B and C together, with the aid of the line indicator 3 and when properly adjusted applies the feed rollers 10 against said sheets and the platen holding the bill sheet and carbon sheet in place. The machine is now conditioned to proceed with the writing and after it is completed and under one set-up of the machine the feed rollers 4 and 10 are simultaneously withdrawn and all of the sheets removed. New sheets are introduced as before and so on.

Heretofore the feed rollers 4 and 10 have been applied and withdrawn by hand in different ways, depending somewhat on the use of the machine and the specific requirements to be attained. One example of this will suffice for the present purpose. Other examples will be given later. It was customary, as hereinbefore indicated, to collate the bill, carbon and ledger sheets in the manner indicated, first simultaneously moving both feed rollers 4 rearward to coact with the ledger sheet L by a rearward movement of a finger piece 11 connected to a rock shaft 12. The rocking movement of this shaft effects an application or a withdrawal of the feed rollers 4 depending on the movement of the finger piece 11 rearward or forward. The same operation of the finger piece 11 controls the movements of the line indicator 3, deflector 6 and ribbon vibrator 9 into and out of operative position. After the feed rollers 4 are applied and the bill and carbon sheets properly positioned, then the feed rollers 10 are separately applied by hand to the bill sheet and the operator proceeds at a single printing operation to fill in the bill and simultaneously make a manifold copy on the ledger sheet. After this is completed a forward movement of the finger piece 11 results in withdrawing all of the feed rollers 4 and 10, freeing all of the sheets and permitting a withdrawal thereof from the machine.

The present construction involves the same mechanism thus far described but includes in addition thereto means whereby a conditioning of the machine as described is automatically effected during the return of the carriage, such return being usually automatically effected by an electrically operated motor, substantially as disclosed in the patent to F. A. Hart, No. 1,567,590, dated Dec. 29, 1925. The parts are such that this automatic conditioning of the machine will differ under different conditions of use, or of purpose to be attained. Tn some cases all of the feed rollers 4 and may be simultaneously withdrawn from the platen and work sheets to the full extent of their movements, the line indicator 3 at the same time being withdrawn from indicating position and the front defiector 6 moved to efiective position to aid in the introduction of a new bill sheet and accompanying carbon sheet after the previously written bill sheet has been withdrawn together with its carbon sheet.

Tu accordance with another method and setup, the feed rollers 10 alone are automatically withdrawn but a slight distance from the platen as indicated in dotted lines in Fig. 5, the rollers 4 remaining on the platen or the work sheet L. This operation is automatically efiected without altering the normal position of the line indicator 3 and front deflector 6, as the same are shown in Fig. 6.

A third method of use or set-up results in automatically moving only the intermediate feed rollers 10 to the full extent of movement thereof away from the platen during the return of carriage, the terminal feed rollers 4 remaining against the platen and the work sheet L or a corresponding record sheet. At this time the line indicator 3 and front deflector 6 are automatically moved from their normal Positions.

I will now describe more specifically the construction and the difierent set-ups by which the results pointed out are attained.

Referring more particularly to Figs. 11 and 12 it will be .seen that, as in the construction disclosed in said application, each feed roller 10- is mounted on a bearing pivot l3 that connects two supportingarms 14 mounted for sliding movement fore and aft of the machine and for a slight pivotal movement around the rock-shaft 12. Thus, each arm 14 has a slot 15 that extends longitudinally thereof and through which the rockshaft 12 extends. A headed pin 16 extends through an opening in each arm 14 and receives a bearing in a longitudinally extending bearing slot 17 in a bracket arm 18. Each bracket arm 18 has a depending arm or member 19 provided atits forward edge with an inwardly extending integral ear 20. The stem of a headed screw 21 passes freely through an opening in each ear and is received at its forward threaded end in a tapped opening in an adjustably mounted support or carrier 22. Said support is substantially C-shaped in cross section to embrace and be supported on a T-shaped supporting bar 23 secured by screws 24 to the front rail 25 of the carriage and extends throughout the length thereof. The support 22. together with the parts carried thereby, are adjustable along the bar 23 and longitudinallyof the axis of the platen and may be secured in its adjusted position by a set screw 26 threaded through the member 22 and adapted at its forward end to bear against the bar 23. A coiled expansion spring 27 surrounds each screw 21, hearing at one end against the head of its screw and atthe other end against the companion ear 20. The force of these springs is exerted on the companion feed rollers 4 or 10 to maintain it pressed against the platen 1, or a work sheet thereon, when the feed roller has been shifted to efiective position, shown in Figs. 11 and 12.

Each support 22 is provided with upward- 1y extending ears 28 spaced apart to receive the companion arms 14 and 18 and other elements to be described. The ears 28 are also pierced to provide bearing openings for the shaft 12. Toggle links 29 and 30 are pivotally connected at 31 and control the movement of each feed roller 4 or 10 to and from operative position. There are two pairs of such toggle links for each feed roller, the

forward end of each link 30 being pierced to receive the shaft 12. Each link 29 carries a pin 16' that, as previously pointed out, slides in a slot 17 in the companion bracket arm 18, so that the latter may form a resiliently mounted support for the forward end of a slide 14 and the parts carried thereby, as well as providing a pivotal connection between each toggle member 29 and the companion slide 14. Each toggle member 30'is provided with an up-standing arm 32, the companion pair of such arms being connected by a cross bar 33 that constitutes a convenient finger piece by which the associate toggles maybe actuated to move the connected feed roller to or from effective position. I

All of the feed rollers 4 and 10 are mounted in the same manner as far as has been described up to this point, though the means whereby the feed rollers are shifted or controlled from the shaft 12 may vary according to the specific requirements of the machine, or the use to which it may be put. In some mstances the toggle members 30 for the feed rollers 4 are loosely mounted on the shaft 12, as indicated in Fig. 4, so that said shaft may turn independently of such members 30 and the associated toggle are not controlled by said shaft. In other instances, as indicated in Fig. 2, each toggle member 30 has a spline projection 34 that is received in a spline groove 35 in the shaft 12, so as to rock therewith. In every instance, however, it is preferredto actuate the toggles of the intermediate feed rollers 10 to release them by a rocking of the shaft 12, although in some instances such toggles maybe actuated to apply such feed rollers 10 independently of a rocking movement of the shaft 12. In order to effect this result a finger 36 (Figs. 3, 5, 11 and 12) is provided for each of the feedrollers 10. Each finger has a hub 37 pierced to receive the shaft 12 and formed with an infits in the. spline groove 35 in said shaft to connect the finger to turn with the shaft. Each hub 37 is received between spaced ears 28 on the companion support 22 (Fig. 12) and its finger 36 underlies an inward extension on one of the pivots 31 of an associated toggle. It will be understood that the two sets of toggles for each of the feed rollers 10 may be straightened through an actuation of the finger piece 33 thereof, and thereby individually apply the companion feed roller 10 while the shaft 12 and the fingers 36 remain in the normal position. However, an anti-clockwise movement of the shaft 12 from the full-line to the dotted line position in Fig. 3, turns the fingers 36 u and results in simultaneously withdrawing 0th of the feed rollers 10 to the dotted line position.

In some instances the automatically operating devices,to be hereinafter described, are set to fully withdraw the'feed rollers 10 to the dotted line position shown in Fig. 3, Whereas, at other times such devices maybe set to remove the feed rollers 10 but a short distance from the face of the platen, as indieated in dotted lines in Fig. 5, for purposes which will presently appear.

Before describing the automatically operating controlling means of the present invention it is deemed advisable to further describe the means whereby motion hereinbefore described is transmitted to the line indicator 3, the deflector 6 and the ribbon vibrator 9, such means being the same, or substantially the same, as disclosed in said application hereinbefore referred to.

The line indicator 3 shown in the present instance is a fine wire stretched between and supported by two arms 39 and 40 (Fig. 6) near the ends of the platen. These arms are fixed to a rock shaft 41 supported by'the platen frame and having fixed thereto a forwardly extending plate-like actuating member 42, the downturned forward edge of which coacts with an anti-friction roller 43. Said roller is carried by an arm 44 operatively connected in the usual, manner with the ribbon vibrator 9 to depress the latter from its normal position, as previously explained, when the front-deflector is moved rearward and downward from normal position.

The arm 39 is the one that is provided with the finger piece 5 at its-upper end, and by which it and the parts controlled thereby may be operated manually at will. The arm 39 is provided with a cam slot 45 in which a pin 46 is seated and works. Said pin 46 is carried by a crank arm 47 operatively connected to the front deflector 6 that is pivotally supported at 48 on the platen frame. 'A contractile spring 49 is anchored at one end on a pin 50 on the platen frame and is connected at the other end to the arm 39 and returns said arm and the parts connected therewith to the normal, Fig. 6, position.

The finger piece 11is provided at the upper end of an arm 51 having at its lower end a hub 52 (Fig. 1) which with the aid of two screws 53 is adjustably secured to the rock shaft 12 to rock it at will and thereby control the feed rollers 4 and 10, or such of said feed rollers as may be under control of said shaft.

Pivoted at 54 (Fig. 6) to the arm 51 is a downwardly and rearwardly extending link 55. The rear end of said link carries a pin 56 that projects and slides in a slot 57 of a supporting bracket 58 adjustably fixed to the carriage. This pin carries a collar59 that constitutes an abutment that coacts with the forward edge of the arm 39 and shifts it forward with the arm. 51, after a certain extent of lost, motion of the last mentioned arm has. first been effected. The result of this is to actuate the arm 39 and the parts controlled thereby at each forward movement of the arm 51 and to afford a return movement of the arm 39 and the parts controlled thereby to normal position when the arm 51 is shifted rearward. Adjustable stops 60 and 61 carried by the bracket 58 limit respectively the rearward and forward movements of the arm 39. A detent 62 is pivoted at 63 and under the force of a spring 64 connected thereto coacts with a depending end 65 of the arm 51 to retain said arm in its forward position against the force of the spring 49.

I will now describe the automatically operating means whereby the rock-shaft 12 is actuated to control the various devices under the control thereof. Referring more particularly to Figs. 6 to 10 inclusive and 13, it will be seen that a sheet metal bracket 66 is secured by screws 67 and 68 to the left-hand bracket arm 69, usually employed to connect the supporting bar for the vertical totalizers to the carriage. The bracket 66 is closed on four sides to provide a sort of a housing but is open at its left-hand side and at the bottom. The right-hand side wall of the housing on the bracket 66 is pierced to receive and form a bearing for the left-hand end portion of the shaft 12 which extends therethrough. Secured to this end of the shaft 12 is a bevel gear 70. Said gear 70 meshes with a second bevel gear 71 loosely mounted on the reduced portion of a spindle 72 '(Fig. 10), that is received in bearing openings in and is supported by front and rear walls of the housing on the bracket 66. A collar 73 surrounds the spindle 72 and is secured thereto by a setscrew 74, said collar bearing against the bracket 66 and holding the spindle against leftward axial displacement (as the parts ap pear in Fig. 10) thus maintaining the parts in assembled relation. A backing up of the screw 74 frees the collar 73 from the spindle 72, enabling the latter to be withdrawn and the parts to be demounted and the gears 70 and 71 to be adjusted relatively to each other nei'avaa for purposes which will hereinafter appear.

The gear 71 has a hub 7 5 that extends through a bearing opening 7 6 in an actuatarm, lever or member 77, shown in detail Fig. 13. The member 77 thus receives a bearing on the hub 7 5 and is supported thereby. A spacing sleeve7 8 also is mounted on the hub 75 and is interposed between the actuating arm 77 and a wall of the housing on the bracket 66. A segmental cut-out or slot 7 9 is provided in the actuating arm 77 below the bearing opening 76 therein. Projecting from the forward face of the bevel gear 71 is a pin 80.

Surrounding the spacing sleeve 78 are several convolutes of a wire spring 81. One depending arm or end 82 of this spring bears against the right-hand side of a fixed pin 83 projecting in from the front wall of the housing on the bracket 66. in the normal position of the parts, shown in dotted lines in Fig. 8, the arm 82 of the spring also bears against a forwardly projecting pin 8% fixed on the actuating member 77. The other end portion of the spring 81 is formed as an arm 85 and in the normal disposition of the parts said arm bears against the left-hand sides of the pins 83 and 8d. The force of the spring 81 is exerted to move the arms 82 and 85 thereof towards each other and against said pins 88 and 84:. The result of this construction is to exert the force of the spring 81 on the member 77 to tend to hold said member in thenormal dotted-line Fig. 8 position, or

return it to said position if the member be swung to the left or right thereof.

The lower depending end 86 of the actuating member, when in the normal efiective position, has a path of movement with the carriage, as the latter moves from left-to-right, which brin s it into contact with an abut ment 87 adgustably fixed on the top plate 88 of the machine, as shown in Fig. 7. As the carriage is returned, say, automatically by the carriage return mechanism disclosed in the Hart patent hereinbefore referred to, the member 77 will engage the abutment 87 causing a turning movement of the actuating member from the Fig. 7 to the Fig. 8 position. This results in bringing the end wall 90 of the slot 79 to bear against the pin 80 causing the gear 71 to be turned. The turning of the gear 71 is transmitted through the intermeshing gear 7 O to the rock shaft 12, to rock the latter and thus efiect a simultaneous release of all of the feed rollers 4i and 10, or such of them as may be under control of the shaft 12. After turning the rock shaft 12 in the manner explained the member 77 reaches the full line Fig. 8 position where it is about to trip off the abutment 87. When it passes such abutment the member 77 will be'restored by the spring 81 to the dotted line Fig. 8 position operating at this time independently of the gear 7.1 and the parts controlled thereby.

stop When the carriage moves in the opposite direction the member 77 coacting with the abutment 87 will be swung to the right from its centered position, but this movement will have no ailect on the pin 80 or the gear 71 and the parts controlled thereby. As soon as the member 77 passes to the left of the abutment 87 said member will be returned by its double acting spring 81 to the centered normal position shown in dotted lines in Fig. 8. l prefer to mount the abutment 87 on the machine so that it may be adjusted in the general direction of the travel of the member 77 with the carriage so as to be able to vary or properly time the tripping action of said member. A simple adjusting means for this purpose is to provide the abutment 87 with a foot-piece 91 slotted longitudinally at 92 to receive the shouldered stems of headed clamping or binding screws 93, that are received at their threaded ends in tapped openings in the top plate 88. By loosening these screws from clamping engagement with the foot-piece 91 it may receive a sliding adjustment to right or left and is held in its adjusted position by tightening the screws.

At times it may be necessary or advisable to throw the automatically operating controlling means out of operation or render it ineffective or inoperative. l have provided simple means for efiecting this result. Thus the actuating member 77 is provided with a shoulder or stop 94% (Fig. 13) with which a or latch 95 (Fig. 7 may be brought into cooperation. The stop. 95 is formed as a part of a carrier or latch 96 provided with a linger piece 97 and pivoted at 98 on top of the bracket 66. To the right of its pivot said carrier 96 overlaps an opening 99 in the top wall of the housing of the bracket 66, said opening containing a ball or detent 100. A leaf spring 101 is secured at one end, as at 102, to the top wall of he bracket 66 and bears upward at its opposite end against the ball and presses it against the member 96 to hold it in either the effective or inefiec tive position to which it may be shifted around its pivot 98. When in the effective position the member 96 has its stop 95 in the path of return movement of the stop 94 and holds the member 77 in the dotted-line Fig. 7 position, where it will clear the abutment ill!) llED 87 in the forward and return movements of rec move those feed rollers which are controlled by the rock shaft 12 but a short distance from the face of the platen, as indicated in dotted lines in Fig. 5, instead of moving them to the full extent of their releasing movement,

as indicated in dotted lines in Fig. 3. In the first instance referred to a work sheet is released without removing the line indicator 3 from indicating position and without shifting the front deflector 6 from its ineffective position to its effective position. In the second instance referred to above the line indicator is automatically shifted to ineffective In order to set the parts so that only the feed rollers controlled by the shaft will be moved, and that to a releasing position but a short distance from the platen as shown in Fig. 5, the collar 73 is released, the gear 71 removed and rotatively advanced, say, one tooth relatively to the gear 70. The effect of this is to advance the pin 80 a short distance away from the wall 90 of the member 77, as indicated in dotted lines in Fig. 13. The result is to create a lost motion between the member 77 and the pin 80 so as to pick up said pin later in the movement of the member 77 and transmit less rocking movement to the shaft 12 through the gears 71 and 70. This gives just suflicient movement to the shaft 12 to effect the results pointed out of moving the feed rollers controlled by the shaft to, say, the dotted line Fig. 5 position without moving the line indicator and deflector 6.

The automatic operation of the parts under control of the actuating member 77 is effective in but one direction, the application of the feed rollers and the return of the line indicator and reflector 6 being brought about independently of the actuating member, either by an actuation of the finger piece 11 or by an additional separate application of certain of the feed rollers, depending somewhat on condition of use to which the machine is to be put, as hereinbefore explained.

It will be understood that all of the parts of the control mechanism described exceptv the abutment 87 are carried by the carriage of a front feed Remington machine which is controlled from the rock shaft 12 applied to the platen, the shaft 12 will cause the pin 80 to bring the actuating member 77 to the position indicated in full lines in Fig. 7 tensioning the arm 82 of the spring 81. This provides for effectively holding the member 77 in position to properly coact with the abutment 87 during the return of the carriage and enables the member 77 to be swung to equal extents past the center in its actuating movement and more effectively control the turning ofthe rock-shaft 12 and without any liability of the end 86 binding or locking against the abutment 87.

If the machine is employed, for example, for writing a bill or invoice sheet B and simultaneously making a manifold copy on the ledger sheet L, as previously described, then a rearward actuation of the finger piece 11 will cause the marginal feed rollers 4 to be applied to the previously introduced and adjusted ledger sheet L to hold it in position against the platen. The finger piece 5 may then be swung forward shifting the vibrator down, shifting the front deflector 6 to effective position and moving the line indicator 3 to the forward ineffective position. The bill and carbon sheets are then introduced into position and the finger piece 5 is released to afford a return of the deflector 6 and indicator 3 to normal position. The feed rollers 10 are applied to the sheets by an actuation of the finger pieces 33 and the machine is in condition for writing. When the carriage reaches the end of the line it is returned either automatically or by hand and this will result in operating the actuating member 77 to turn the shaft 12 and release all of the feed rollers 4 and 10, and shift the line indicator 3 to ineffective position and the deflector (i to effective position, at the same time lowering the ribbon vibrator. The machine is thus conditioned for the withdrawal of the sheets L. B and C and the introduction of other like sheets in their place as before indicated. and so on, the operations 'will be repeated for eachbill and ledger sheet to be written.

In the use of the construction, set as previously described in connection with Figs. 4 and 5, a pay roll sheet which may remain in the machine passes from the rear of the platen around the latter and beneath the usual upper feed rollers D (Fig. 6) above the platen at the same time passing beneath the margin feed rollers 4. The rollers 4 remain on the pay roll sheet, being free from splined connection with the rock shaft 12,,as in Fig. 4, whereas the intermediate rollers 10 are operatively connected by the fingers 36 with the rock shaft for releasing movement only, and only to the extent indicated in Fig. 5. It will be understood that, at this time, the gear 71 has been adjusted relatively to the gear to attain this result. As has been previ- 7 is automatically eilected, on the return of the carriage, by the actuating member 77 as previously described.

A third method of usingthe machine involves edecting an automatic rocking of the shaft for the full extent of its movement and in having the actuating toggle arms for the center feed rollers 10 splin'ed to the rock shaft, as indicated in Fig. 2, and in having the actuating toggle arms for terminal feed rollers tree from such splined connection, as

indicated in Fig. 4. With this arrangement the terminal feed rollers 4 remain in contact with a record sheet that is retained in the machine and receives an accumulation of the various bills written on the machine. The rollers a in this setting of parts are unatfe-cted by the automatic action of the rock shaft 12. When the latter is automatically rocked to its full extent, as previously pointed out, the intermediate feed rollers 10 are released, the line indicator 3 is moved from effective position and the front deflector 6 is moved to edective position. The written bill and carbon sheet are then removed and new ones inserted and adjusted, The finger piece 11 is then moved rearward to apply the feed rollers 10 and shift the line indicator and deflector 6 to normal position and the operator may proceed as before The present construction aids materially in quickly, edectively and automatically controlling the parts under varying conditions of use of the machine and in proper sequence (as in the usual Remington front feed machine referred to on page 4 of the specification), relieving the mind of the operator in I eilecting certain of the operations that were formerly efiected by hand in given order relatively to the return of the carriage, etc. Theoperation of the machine is therefore mater ally simplified andspeeded up and assurance given of a proper operation of the parts, and in proper sequence.

lnstead of using toggle arms 30 with and without spline projections 34:, depending on the conditioning of the machine for the specific character of work to be produced, I

may use a construction in which screws, such as the screws 53, are employed for connecting the toggle arms 30, to or disconnecting them from the shaft 12 at will. However, in-

\ asmuch as each machine is usually set up for a given class of work only, and the construction employing or devoid of the spline projections 34, as may be required, constitutes a simpler and more compact construction I prefer to employ it.

While I have described in detail a form of construction in which the invention may be clothed, it should be understood that this is by way of illustration and that various changes may be made in the construction, and that parts thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims.

What l claim as new and desire to secure by Letters Patent is:
