TYPEWR-ITING MACHIVNE.

Application led December To all @07mm it may concern.'

Be it known that l, EDWIN E. Banner, citizen of the United States, and resident of lil ew Rochelle, in the county of l."estchester and State of N ew York, have invented certain new and useful mprovements in rlypewriting ll/lachines, of which the following is a speciication.

My invention relates to line spacing mechanism for typewriting machines and its general object is to provide new and improved mechanism of the character specified. specilic object of the invention is to provide for operating pawl and ratchet line spacing f devices located at one end of the platen by a line spacing handle located at or near the opposite end of the platen.

To the above and other ends which will hereinafter appear.l my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

rlhe preferred form of the invention was designed primarily for the llo. 10y Remington typewriting machine, and in carrying out the invention l have dispensed with the line spacing handle usually provided and mounted near the right hand end of the plat en and have instead provided a line spacing handle or finger piece mounted on the4 carriage near its left-hand end and connected with the usual line spacing pawl at the right which has been retained. The present form of my invention will be described in detail in connection with the accompanying` drawing wherein- `Figure 1 is a fragmentary top plan view of the carriage of a No. 10 Remington typewriting machine embodying my invention.

Figure 2 is a fore-andaft vertical sectional view taken on a plane indicated by the section line 1 1 inllig. 1 and looking in the direction of the arrows at the said line.

Figure 3 is a fore-and-aft vertical sectional view taken on a plane indicated by the section line 22 in Fig. 1 and looking leftward as indicated by the arrow at said line.

Figure l is a fragmentary view of a detail, and

Figs. 5 and 6 are perspective views of parts hereinafter referred to as supports or brackets.

broken away or sectioned for the sake .of clearness. l y

Referring iirstto Figs. 1 and 2, the carriage of the N 0.10 Remington `machine comprises a rectangular truck composed of a front bar 1 and parallel rear bar (not shown) which are connected by end bars 3 and 4. Shiftably mounted on the truck is a platen frame vcomprising end bars 5 and a cross rod 6, said frame being` connected with the truckvby links 7. Rotatably mounted on the platen frame is a platen 8 having axle portions 9 ywhich pass through the end bars 5. @peratively connected with the platen at its right-hand side is a line spacing ratchet wheel 10 with which co-operatesa line spacing pawl 11, said pawl being pivoted at 12 to a pawl carrying arm 13 which is rotatively mounted on the right-hand axle section 9. A roller detent 14 mounted on a spring arm 15 co-operates with the teeth of the ratchet wheel 10. The parts above described.7 are common to the Remington machine.

In carrying out my present invention I have dispensed with the usual means for actuating the pawl 11 and provided instead a train of mechanism which is operated from the left-hand end or side of the carriage, this novel train being supported by a pair of brackets which are detachably lmounted on the carriage truck, one at the right and one at the left side thereof. Said brackets are shown detached in Figs. 5 and 6 and are respectively designated by the numerals 16 and 17. rfhey are preferably made of sheet metal, and lthe right-hand bracket 16 com` prises a flat body portion 18, an upright end portion 19 and at vits reary an upwardly eX- tending tab or ear 2O which is curled or bent to provide a bearing for a stop screw 21 which is provided with a check nut 22. The bracket 16 is also provided with an upstanding bearing post 23 having a flange 24, said post being staked or rivetedy to the Abody portion 18. The post 23 is located at or near the middle of the bracket considered from fro-nt to rear, and at` theforward end of the bracket there is staked or'otherwise `riiXed to the body portion 18 an upright flanged post or linger piece whose surface may be knurled or roughened as shown in the drawing. The brackety 16 with the parts mounted on vit as described is secured to the top of the truck bar 3 near its forward end by headed screws 26 which pass through openings indicated at 27 in the body portion 18 and are threaded into the end bar 3. ivotally supported on the post 23, as shown in Figsl and 2, is a bell crank lever 28, said lever having a downwardly extending hub 29 which fits over and bears on the post 23, the lower end of the hub 29 resting on the flange 24. A headed screw 30 threaded into the post 23 at the top prevents accidental upward displacement of the bell crank lever 28, the head of said screw overlying in part the tno-p face of said lever. @ne arm of the ball crank lever 28 extends forward from its bearing and the other arm extends inward or leftward, the leftwardly extending arm being connected by a fore-and-aft link or thrust rod 31 with the pawl 11. Thek forward end of the link 31 is provided with an upwardly extending angular portion 32 which is hooked through a round hole in the bell crank arm, while the rear end of the link terminates in a laterally projecting angular portion 33 which is hooked through a hole in the pawl 11 below the pivot 12. The con struction is such that while the link 31 may be readily detached when either of the connected parts 11 or 28 is removed, yet said link is so constructed and connected that accidental detachment cannot take place when the. parts are secured in position. The forwardly extending arm of the bell crank 23 has connected to it the right-hand end of a long link or tension rod 34, said link 34 at its right-hand end terminating in a downwardly extending hook portion 35 which engages in a hole in the bell crank 28. The link or tension rod 34 extends longitudinally of the platen and of the carriage, said link being preferably arranged or disposed behind the usual scale bar 36 and above the rear portion of the stop rack bar member 37 that is fixed to the top of the front bar 1 of the carriage. The scale bar 36 is secured to the topof the stop rack bar and, being narrower, leaves at the rear a recess 36a in which the link 34 is conveniently received. rEhe left-hand end of the link 34 terminates as most clearly shown in Fig. 4 in a downwardly bent extension or end portion 34aM on which is loosely mounted a nut 38 provided with a hexagonal head 39. rThe lower end of the extension 34a is spread or upset to prevent detachment of the nut 38, 39. The exterior of the body of the nut is threaded to adapt it to engage in a tapped opening formed in the rear arm 49 of a lever niember of the first order which further com* prises a forwardly extending arm 41V terminating ina downward extension or finger piece 42. Said member or lever 40-42 is provided with a hub portion 43 which is drilled out to fit over and bear on a post 44, said bearing post being provided with a flange 44a on which the hub of the lever 42 is adapted to rest. A screw 45 is threaded intov the top of the post and is provided with a head which in part overlies the hub 43 and prevents upward displacement of the operating lever 40-42 rThe post 44, 44L is staked into or otherwise fixed to the body portion 46 of the left-hand bracket 17, said bracket further comprising an angularly disposed upright end portion 47. At its rear the bracket 17 is downwardly bent or offset, the downwardly bent rear portion being formed with a slot indicated at 48 which is adapted to receive a headed screw 49 that is threaded into the truck bar 4. 50 (Fig. passes through the bracket and is threaded into the carriage truck, the two screws 49 and 50 detachably securing the bracket 17 to the left-hand end of the carriage. 1n order to provide room for the bracket 17, the usual left-hand release lever of the machine, which lever has a key or finger piece that overlies the front lefthand corner of the carriage truck, is replaced by a release lever 51 which is pivo-ted at 52 to the side of the truck or carriage frame and terminates at its front end in a finger piece or key 53. The release key or finger piece 53 unlike the prior construction, is bent leftward from the body portion 51 instead of rightward and thus leaves the corner of the carriage truck clear for the attachment of the bracket 17. The inner end portion 47 of the bracket 17 abuts against the left-hand ends of the bars 36 and 37, said portion 47 being cut out or shaped to conform to the shape of the bars whose ends are housed or covered by the said end portion 47, a notch, indicated at 54 in the part 47 affording a passageway for the connecting rod or wire 34. Similarly the end portion 19 of the bracket 16 covers the right-hand ends of the bars 36 and 37, said, portion 19 being cut away as indicated at 55 to afford passageway for the connecting rod 34. The provision of the end portions 19 and 47 on the two brackest 16 and 17 enables me to dispense with the usual angular end pieces that cover the ends of the sca-le and rack bars. rfhe disposition of the rod or wire 34 in the recess 36 formed by the bars 36 and 37 renders the rod inconspicuous and serves also partly to protect it. 1n order further to guard and protect the long rod or wire 34 there are preferably provided several, two in the present instance, fingers or curved sheet metal guards 56. These are detachably secured by screws A57 to the top of the rack bar member 37 and curve over from the front and cover 'the top of the rod 34. The ngers 56 are disposed at opposite sides of the usual pointer 58 which curves forward over the top of the rod 34 oppositely from the fingers 56.

The handle or finger piece 42 in which the forward arm 41 of the'operating lever ter- Another headed screw' minates extends downward at the yleft of the carriage, overhanging the rear portion oi the keyboard oi the machine in a position convenient to the left-hand of the operator. lt will be understood that the handle serves the do-uble purpose of restoring the carriage from lett to right and also ot concurrently line spacing the platen by actuating the pawl and ratchet mechanism at the opposite or right-hand end of the platen. Normally the parts may be arrested in the Fig. l position by reason of the contact of the bell crank 28 with the rear edge of the relatively stationary part 19 which acts as a stop Jfor the operating train; but any other suitable stops may be provided. During line spacing operationsv the handle 42 is pushed toward the right, turning the operating lever on its fulcrum and swinging the rear lever arm 40 toward the left, thus communicating a leftward pull to the rod 34 which will thereby be moved generally longitudinally le'litward. This leftward movement of the rod will in turn transmit a rotary movement to the bell crank 28 swingthe leftwardly extending arm of saidy bell crank rearward and thrusting the link or rod 3l rearward, thereby actuating the pawl 11 and causing it to co-operate with the ratchet wheel l() in the usual way to turn the ratchet wheel and the platen through one or more units of line space distance. lt will be understood of course that the extent of line space turning movement communicated to the platen will depend on the adjustment of the usual line space regulator (not herein shown).

In order to limit movements of the actuating train in line spacing direction and also to overcome a tendency on the part of the platen and platen frame to shift or move upward as the result of an excess of power applied to the line spacing handle, the stop screw 21 is provided. The forward end of this screw lies in the path of movement of the horizontally arranged bell crank 28 and said screw is so adjusted and locked or set by the nut 22, that it will arrest the hell crank when the full line spac-y ing turning movement thereof has been completed, thereby preventing excess move- Y ments of the bell crank which might be communicated through the link 3l to the pawl ll.

For the purpose of restoring the train of mechanism, beginning with the handle 42 and terminating with the pawl l1, a single restoring means only is necessary; this means being in torni of a wire spring 59 which is coiled around the hub 29 and the {lauge 24, said spring being confined between the top of the bracket part 18 and the under side ot the bell crank 28. The lower end ot the spring 59 is extended straight towards the rear and abuts against theinner side of the ear 2O which will hold' it againstl The upper end of unwinding movement. the spring 59 is extended outward away from the coil and is held against unwinding movement by a pin 60, which extends downward from the under side of bell crank 28, the straight end portion of the spring pressing againsty said pin. lt will be understood that the force of the spring 59 transmitted to the bell crank 28 through the pin 60 tends constantly to turn said bell crank in counterclockwise direction when viewed from the top as in F ig. l and that said spring will restore the bell crank and the parts connected to it to normal position after operation. lt will further be apparent that the spring 59, acting through the bell crank will pull the rod or link 34 towards the right, this movement of pull or tension being communicated from the lett-hand end of the rod to the operating lever 40-43. At this point it may be noted that the detachable connection comprising the nut 38, 89 between the rod 34 and the lever arm 40 is of ccnsiderable convenience in that it enables me to dispense with turning movements of the long rod 34 during adjustments, and requires only an adjustment of the nut 38, 39 by a spanner or other tool in order quickly to connect the rod 34 with the operating lever. i

It will be seen that the left-hand line spacing mechanism provlided by my in,- vention is simple in construction comprising few parts which may be readily attached to a machine and connected with the line spacing pawl without requiring material alteration in the regular construction. The mechanism is edective in operation and the parts are comparatively light. rlhe rod 34 since it is subjected to` tension stresses only and never to compression may be made of comparatively fine wire. The connections between the line spacing handle and the pawl are positively attached and constantly connect the two parts; and a singlespring only is needed to restore the entire train of part-s after a line spacing movement.

Various changes may be made without departing from my invention.
