TYPEWRITING MACHINE.

Application filed December 30, 1922. Serial No. 610,058. I

To all whom it may concern:

Be it known that I, EDWIN E. BARNEY.

citizen of the United States, and resident of ploy a normally engaged platen clutch for .maintaining the line spacing wheel and platen normally connected to turn together.

' In such constructions it is necessary to first rel-ease the clutch by a separate operation before the platen can be turned independently of the line spacing wheel for differential spacing, or unlimited turning movement of the platen, and then after such spacing has been effected bring about as a separate operation a reestablishment of engagement of the clutch, in order that the next operation of the line spacing handle may be effective to turn the platen. This occupies much time, and in other respects is open to disadvantages which. will be hereinafter pointed out. w

One of the main objects of my invention is to provide simple and efficient mechanism for overcoming these various disadvantages. Tothe above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims.

Fig. 7 is a fragmentary detail front view showing a slight modification of some of the parts.

In accordance with the specific embodiment of my invention disclosed in the present instance the platen clutch is normally ineffective, so that the platen normally is free to be turned at all times independently of the line spacing wheel, and the clutch is automatically actuated to close it at each line spacing motion transmitted to said wheel may in turn be transmitted to the platen, and no separate preliminary operations of clutch to connect or disconnect it is required. By my invention, I automatically condition the machine for regular and irregular line spacing and thereby materially save the operators tlme, as well as eliminate some of the noise usually produced, as will presently appear.

I have shown my invention embodied in the present instance in a #12 Remington machine, only so much of said machine being shown as is necessary to arrive at an understanding of my invention in its inclusion therein. It should be understood however, that the invention is not restricted to embodiment in such machine but may be employed generally in typewriting or like machines whenever found available.

The line spacing mechanism employed in the #12 Remington machine is somewhat similar to that disclosed in the patent to Oscar Woodward No. 918,938 dated April 20, 1909. The clutch mechanism per se is of the same general character as that disend plates 7 united by cross bars 8, 9 and 10 and is connected by links 11 and 12 to the end bars of the truck. A cylindrical platen 13 is supported in the platen frame in the usual manner, the right-hand end only of the platen andthe means for supporting it being shown in the present instance.

Referring more particularly to Figs. 3 and 4 it will be seen that the right-hand platen head 14 is secured by screws 15 to the core 16 of the platen. An outwardly extending nipple 17 on the platen head receives a bearing in a headed bushing 18 screwed from the inner side into a tapped opening in the right-hand end plate 7 of the platen frame. A look nut 19 is threaded onto the bushing on the opposite side of said end plate to hold the bushing'tixed in position. The bushing is extended to the right at 20 through an upright opening 21 in the right-hand end bar 3 of the truck, and is surrounded by a buffer spring 22. This spring coacts with two oppositely disposed screws 23 and 24, the former shown in the present instance threaded down into contact with the buffer spring 22 to prevent a case shifting movement of the platen; the machine in which the present invention is shown embodied being equipped to write in but one case. It is however immaterial for the purpose of the present invention whether or not the platen receives a case shifting movement.

Mounted loosely on the platen head 14 is an annular line spacing wheel 25 provided with teeth26. The line spacing wheel is held in place on the platen head by an annular plate 27 detachably secured to the head by screws 28. The platen head 14 has a central bore which constitutes a bearing for a spindle 29 provided at its outer end with a finger'piece or wheel 30. The spindle is formed with struck-up spline projections 31 thereon, said projections extending into spline slots 32 provided in an inwardly extending nipple 33 on the platen head'14. By this construction the platen, platen head 14 and the spindle 29 are fixed to turn together, although the spindle iS'free to receive an independent longitudinal movement for the purpose of controlling the platen clutch, as will hereinafter appear. The inner end portion of the spindle 29 passes through an opening in a cap 34 secured to one end of a tubular extension 35 that surrounds the spindle and is screwed, at 36, on to the nipple 33. The spindle 29 carries at its inner end a fixed cross pin 37 on which is mounted to slide transversely of the spindle a sheet metal frame 38. Mounted in the frame on opposite sides of the spindle are two rollers 39 which coact with the inclined faces'40 on two lever-like clutch members 41. These members 41 are loosely seated in two radial slots 42 in the platen head, each memher being held snugly between the side walls of its slot, but supported at 43 on the bottom wall '44 to turn radially. Each clamping member 41 is provided with two clamping jaws 45 and 46 between which is received an inwardly extending circular flange 47 on the line spacing wheel.

From the foregoing description it will be understood that when the spindle 29 and the parts carried thereby are shifted outwardly to the dotted line'positionshown in Fig. 3, the rollers operating on the inclined faces 40 will shift the free. ends of the members 41, causing the clamping jaws 45 and 46 to exert a tenacious binding or clamping action on the line spacing wheel, thus connecting the line spacing wheel and platen to turn together. When, however, the spindle is shifted inwardly to the full line position shown in Fig. 3, the force exerted by the rollers 39 on the members 41 will be relieved, thus relieving the clamping pressure exerted by the jaws 45 and 46 and permitting the platen to be turned independently of the line spacing wheel. Atthis time the line spacing wheel is held against turning movement by the usual roller detent 48 that bears against the teeth 26 in the interdental spaces thereof, and is spring pressed to said position by a spring 49 that carries the roller 48 atits forward end, and is secured at its'rear end to the platen frame by a screw 50.

The line spacing mechanism of the machine in addition to the parts described includes a line spacing actuator. While any suitable actuator, or actuating means, may be employed, those shown in the present instance are the means usually employed in the #12 Remington machine and comprise an actuator, finger piece or handle 51 forming partof a rock shaft 52 mounted in a bearing 53 secured to the right-hand end bar 3 of the carriage truck. Within the bearing 53 and surrounding the shaft 52 is a spring 54, secured at one end 55 to the rock shaft and at its other end 56 to the bearing 53. The force of this spring is exerted to return the line spacing handle and the parts connected therewith to normal position. The rear" end of the rock shaft 52 has a crank arm 57 detachably fixed thereto by a screw 58. This crank arm is apertured at its free end to receive the bent end of an upright wire link 59. The lower bent end of the link extends through an opening 60 in one arm of an actuating member or angular lever 61, pivoted at 62 on the right-hand end bar 3 of the truck. The other arm of this angular lever carries a laterally extending headed pin 63 which is received in a slot 64 extending longitudinally of a link 65. This link extends fore and aft of the machine and is connected by a pivot 66 to a line spacing shouldered pivot screw 69 on a pawl carrier 70 that has its lower annular end mounted on the bushing '18. In order to limit the pivotal movement of the pawl 67 on its carrier the pawl is provided with a laterally projecting pin 71 .(see Fig. 1) that extends into a hole 72 in the pawl carrier.

In operation, the movement of the handle 51 to the right is effective through the intermediate train of connections to first move thepawl 67 around its pivot 69, cansing the pawl to be thrown into engagement with the teeth of the line spacing wheel.

.After such engagement has been effected the pawl 67, pawl carrier 70 and line spacing wheel will turn together until the heel 73 of the pawl engages the roller detent 48, and the crank arm 57 is arrested by an adjustable screw stop 74 (see Fig. 1) on the side bar 3 of the carriage truck.

In order to provide for varying the extent of line spacing effected at each actuation of the handle 51, the usual hand set de vices are provided. These include a finger piece 75 connected to a locking pin 7 5 (Fig. 1) mounted to move up and down in a hollow support 76 and pressed down therein by an expansion spring 77 contained within said support. The lower end 78 of the locking pin 75 is adapted to enter any one of three locking recesses 79 in a segmental locklng piece 80, fixed to the right-hand end plate 7 of the platen frame by a screw 81. The nember or hollow support 76 is fixedly secured to a stop carrier 82, the lower annular hear- .ing end of which is supported on the bushing 18, as shown in Fig. 3. An integral stop 84 (see Fig. 1) is bent to the left from the member 82 and extends into the path of and limits the return movement of pawl carrier 70 to normal position. The normal position of the pawl carrier and pawl may thus be varied to any one of three positions, and thus vary the 'extent of line spacing to the extent of one, two or three teeth of the line spacing wheel.

The features of the construction as thus far described, except for slight changes, are like those embodied in the No. 12 Remington machine. It will he observed, however, that in the present construction the spring usually contained in the tubular extension 35,

- apd by which the platen clutch normally is maintained closed, is omitted; provision being made in the present construction for maintaining the clutch normally open, as will presently appear. -Moreover, the employment of the slot 6 1, which I have introduced in the link provides a lost motion connection, whereby the first part of the operation of the line spacing handle is effective to move the lever 61 independently of the pawl actuating link 65, for purposes which will hereinafter appear. Any suitable means may be provided for disengaging the line spacing pawl from the teeth of the line spacing wheel on the return of the line spacing handle irrespective of said lost motion connection and the position to which the line spacing regulator may be set, i. e., for one, two or three teeth spacing. In

-t he present instance, I provide for the purpose alight spring 85 (Figs. 1 and 2) coiled around a washer 86 on the shouldered pivotscrew 69, and fastened at one end to the line spacing pawl 67 and at the other end to the pawl carrier 70. The force of this spring is exerted, on the return movements of the parts, to position the pawl 67 relatively to its carrier as shown in Fig. 1, irrespective of the position to which the line spacing regulator is adjusted. Consequently the actuating link 65 will always, at the return movement of the parts, be positioned so as to afford a lost motion of the lever 61 before theline spacing pawl is actuated, and release the pawl from the line spacing wheel. This lost motion is utilized in connection with features now to be described to bring about automatically an actuation of the normally open platen clutch to close it before line spacing movement is transmitted to the pawl 67 and the line spacing wheel, so that a spacing of the wheel by the handle is effective to produce a corresponding definite predetermined extent of line spacing movement of the platen. The usual actuating lever 61 is modified by having one arm thereof extended at 87, and mounted on a pivot screw 88 on the right-hand face of said extension 87 is an anti-friction roller 89. This roller is received in a yoke-like member '90 substantially U-shaped in cross section, providing parallel front and rear walls 91 against which the periphery of the roller 89 is adapted to hear. The member 90 is fixedly connected to the yoke-like end 92 of an actuating memberor lever 93, and in effect constitutes a fixed part thereof. Theend 92 of this lever straddles the' right-hand end bar 3 of the truck, and is pivoted on a vertically disposed pivot screw 94 threaded at its lower end into a tapped opening in the yoke 92 and turning freely in a bearing opening in'the bar 3. The lower member of the yoke-like part 92 of the lever 93 is extended to the right and rearward to'provide a lever arm with a rounded end 95. This end of the lever is received between a collar 96, secured by a screw 97 on the 'spindle 29, and a flange 98 formed on the hub 99 of the finger wheel 30, said hub and finger wheel being secured to the spindle by a screw 100. It will be understood that these devices provide a train of positively connected elements between the line spacing handle 51 and the spindle 29, to control the latter by the former.

As the handle 51 is moved to the right,

lln

the arm 87 will be moved down effecting a rearward camming action against the member 90 of the lever 93, turning the latter on its pivot 94. This moves the rear end of the lever 93 to the right, moving the spindle 29 and the parts carried thereby to the broken line position shown in Fig. 3, and closing the platen clutch to cause the line s acing wheel and platen to turn together. lghen this movement of the spindle is completed the roller 89 reaches the curved portions of the walls 91 that are concentric with the pivotal axis of the lever 61 at this time and act as a dwell to hold the clutch closed during the further downward movement of the arm 87. The closing of the platen clutch in the manner described takes place before the pin 63 reaches the rear end of the slot 64 to actuate the link 65 andline spacing pawl, such actuation of the pawl taking place while the roller 89 rides on the curved dwells of the walls 91, and while the clutch is held closed.

After the completion of the line spacing movement of the platen as just described, a release of the handle 51 by the operator allows the spring 54 to return the handle and the parts connected therewith to normal position, shown in Fig. 1. The efiect of this return movement of the handle is to shift the rear end of the lever 93 to the left, thereby moving the spindle 29 and the parts carried thereby from the dotted to the full line position shown in Fig. 3, thus opening or releasing the platen clutch. The parts remain in this normal condition until the line spacing handle is again actuated when the clutch will be automatically closed before theline spacing wheel is turned, as in the previous actuation of the line spacing han- When the spindle 29 is moved to the releasing position as described, the platen may be turned independently of the line spaclng wheel, yet the clamping jaws 45 and 46' exert suflicient frictional'resistance on the,

line spacing wheel, together with that exerted between other parts moving with the platen head relatively to non-moving parts,

to hold the platen against accidental, displacement from the position to which it may e turned.

In Figs. 5 and 6 I have shown another form of construction to accomplish the same general ends as that previously described, and operating in, the same general manner. In the previously described construction a train of positively connected elements is employed intermediate the line spacing handle 51 and the clutch spindle 29. and the returning spring 54 acting through said positively connected elements is relied upon to move the spindle to the releasing position. In the second form of construction I rely on the beveled or inclined faces 40 of the clutch 'posite direction by the end 101 of the lever 61 coacting with the forward contact edge of a plate 103 fixed by a screw 104 to the yoke-like end 105 of a lever 106 pivoted at 107 on the truck. The lever 106, except for the changes pointed out, is like the lever 93 in the first described construction, and co'acts, as shown in Fig. 6, with the flange 98 to move the spindle 29 outwardly.

It will be seen that the slight curvature 108 of the contact edges of the plate 103 corresponds to one of the curved dwells 91 in the first described construction.

It will be seen that in both constructions described, the normally released platen clutch conditions the machine so that the platen may always be turned irregular unlimited distances independently of the line spacing wheel (which at this time is held against turning movement under the restraint of its detent) by a mere turning of the finger wheel 30, by a mere turning of the finger wheel usually employed at the other end of the platen, or by a backward or forward withdrawal of the work sheet without releasing the usual paper feed rollers. This allows a quick lntroduction or withdrawal of a work sheet without producing the loud clicking noise which ordinarily is produced byothe spring detent 48 clicking over the teeth of the line spacing .wheel as the latter turns with the platen in rapidly introducing a work sheet into or withdrawing it from the machine. On the other hand, whenever the line spacing actuator or handle is actuated it is effective to produce regular line spacing of a predetermined extent. It also will be seen that none of the 'operators time or attention is occupied in closing and opening the platen clutch, suchroperations being incidental to the operation of the actuator or handle for line spacing and therefore automatically effected.

While the present invention was devised as a part of the equipment of a machine for rapidly handling telephone toll slips or Ill blanks, in which the ,slips may be rapidly platen, as hereinbefore pointed out. However, this is unnecessary so far as the action of the devices of my mvention are concerned; the action of such devices being the same'whether' the screw 23 be positioned as shown or be backed up to permit a case shifting movement. .In the latter event a collar 96? of increased diameter secured to the spindle 29 by a screw 97 should be employed, as shown in Fig. 7. Also a flange 98 of increased diameter should be employed on the hub 99 of the finger wheel 30, as shown in this last mentioned figure. This enables the lever 93 properly to coact with the members 97 and 98 in either case position of the platen.

"I have shown and described my invention with considerable detail,and in different forms inwhich it may be embodied, and

have shown the inventionin the present instance incorporated in a No. 12 Remington machine in which it may be readily included without materially changing existing features of such machines, except by the omission of parts from and addition of parts thereto. However, I believe that I am the first to have provided a construction in which in the normal condition of the machine the-platen may be turned irregular unlimitedextent's free from the control of its line spacing and detent mechanism, and

yet is held against accidental displacement from the position to which it is turned, and in whicha mere actuation of the line spacing actuator or handle is eifective, neverthe- 7 less, to turn the platen a definite line space distance, eliminating all separate preliminary setting or conditioning of the machine, and wish to be understood as claiming broadly such a construction. It will .be

understood therefore that many changes may be made in the construction without departing from the invention as it is defined in the accompanying claims.
