SPECIFICATION forming part of Letters Patent No. 614,943, dated November 29, 1898A. Application filed October 19, 1896. Serial No. 609,332. (No model.)

To all whom, it may concern,.-

Be it known thatwe, WILLIAM R. Fox and GLENN J. BARRETT, citizens of the United States,residing at Grand Rapids,in the county of Kent and State of Michigan, have invented certain .new and useful Improvements in Type-Vriting Machines, of which the following is a speciiication, reference being had therein to the accompanying drawings.

Our invention relates to type-writing machines of that class'in which pivoted key and l type bars are employed and the type-bars are arranged in basket form.

The object of the invention` is to improve the whole machine both in the manufacture and operation thereof.

The machine includes the particular arrangement and operation of the connection for securing the platen to the carriage.

It further includes the escapement mechanism and the link connections between the key-bars and the type-levers, and it also includes the arrangement of the writing-scale.

It further includes the details of construction, as will be hereinafter described, and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the machine with the carriage removed therefrom. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a detail plan view of the carriage. Fig. 4 is a detail of a portion of the rear of the inner part of the machine, showing the bell and ribbon-feed mechanism. Fig. 5 is a detail front elevation showing the marginal stop device. Fig. 6 is a detail front sectional view of one end of the machine, showing the upper-case lockingplate, the semaphore, and part of the connecting-links between the keylevers and the type-bars. Fig. 7 is a det-ail View of the upper case and supplemental keys. Fig. 8 is a detail end view showing the platen raised for inspection of the work. Fig..9 is a similar view showing the platen lthrown forwardly of the front bar of the carriage to expose the type.. Fig. 10 is a detail showing the connection between the horizontal and vertical parts of the key-levers. Fig. 11 is a detail side elevation of the key-lever,

type-bar, connecting-link between the same, the guide-bar for said link, and the bracket for supporting said bar. Figs. l2, 13, 14, and 15 are detail views. Figs. 16 to 2l are detail views of modifications.

The frame .1 is of substantially the ordinary form except that it has the parallel tracks 2 2 on the top thereof, these tracks being arranged near the front and rear edges of the frame and extending almost the entire 6o length of the same. V shaped ways are formed inthe tracks to receive the balls 3, suitable stops 4 projecting into the Ways to limit the movement of the same. The carriage 5 is of rectangular form, and the lon- 65 gitudinal bars thereof are recessed in their under faces to form ways for the balls 3, similar to those in the tracks, with the exception that a widened rectangularrecess having a flat bottom wall is made in the front bar of 7o Ithe carriage instead of a V-shaped recess. The two rear recesses having the balls between thus aline the carriage when it is placed in position, the wider recess allowing a slight movement sufcient to compensate for any difference in alinement between the recesses in the tracks and those in the carriage. The carriage is wholly supported and movable on the balls. The front portion of the carriage is held down in place by a clip 6', secured in 8o a recess in the rear side of the said front bar, having an inwardly-turned lower end that extends into a groove 10, running longitudinally of the rear side of the front track 2.

A stop 3 is placed in this groove, against 85 which the clip 6 strikes when the limit of the carriage movement to the left has been reached. The rear bar of the carriage has its upper face cut away at its front edge to form the inner way 9, along which a roller 10 9o rides as the carriage is reciprocated. This roller is journaled on a stud projecting from the rear face of a bracket 11, bolted to the intermediate front part of the front side of the rear track 2, and serves to hold the rear part of the carriage down in position.

The platen 12 has the shaft 13 extending from each end thereof, on which the plates 14 are fixed. Arms 16 are pivoted at one end to the shaft 13 and are separated from the plates roo of the front bar.

14 by suitable collars or space-blocks 15, carried by said shaft. The opposite ends of the arms 1G are pivotally connected to the ends of links 17, having enlarged bosses 17 journaled on a rod 18, running longitudinally of the carriage and fixed in end bars thereof. On these links and arms the platen is moved from its normal position from between the side bars of the carriage or in rear of the front bar to the position shown in Fig. 9, in front In the latter position the type are exposed and may then be cleaned. The links 17 have pins or lugs 172 extending inwardly therefrom, upon which the forward ends of the plates 14 rest when the platen is in normal position. The plates 14haveheaded studs 19 extending therefrom and adapted to rest in the forked end of the links 20, pivoted to the inner faces of the end plates of the carriage, when the platen is in normal position. These links 2O have arch-shaped slots extending through them, which receive the pins 2l, projecting from said end bars, and the links are thus limited in their movement and held at all times in approximately the position to receive the studs 19 in their forked ends. The studs 19 are held against accidental displacement by latches 21, pivoted on the same pin as the links 20, having hooked ends, which normally hold the studs in their seats in said links, flat springs 22, secured to the links, having inwardly-bent ends to engage and hold the latches in position. Pieces 23 project laterally from the top of the latches to provide ready means for throwing them back to permit the removal of the studs 19 from their seats when the platen is to be thrown into the position shown in Fig. 9, and these pieces 23 strike and rest against the upper faces of the said end bars of the carriage when thrown back, and thus hold the latches in such a position that they may be readily pushed into place again.

Then the platen is raised or tilted on its shaft 13 to the position shown in Fig. 8, the links 1G and 2O are drawn toward each other. A stop 23 may be placed so as to project inward from the end bars gof the carriage into the path of the link 20 to limit the movement of said link,and thereby the amount the platen may be tilted.

The plates 14,intermediate thereof,have oifsets or enlargements near their upper edges, to which are pivoted the side bars 24, carrying the writing-scale 25. These bars have the central portions curved to pass around the shaft 13 and the collars lined to the same, the

radius of the curve on the edge nearest to the collars being about the same as the radius of the collars. Thus when the platen is raised, as shown in Fig. S, the upper edge of the writing-scale will rest against the platen at the `bottom of the printing-line, the curved part of the side bar resting on the collars on theshaft When the platen is lowered,

lelsswung away from the platen by 6 ecting outwardly from the side bars, coming into contact with the upper edges of the arms 16. The scale is held about two line-spaces above the printing-point by these pins resting upon the arms when the platen is in normal position. The scale can be tilted to make erasures when the platen is raised.

The platen is rotated by a toothed wheel 27, liked to one end thereof, which is engaged and turned step by step bya pawl 2S, pivoted to a bell-crank lever 29, pivoted on a boss 30, fixed toa rod 31, extending between and fixed immovably in the ends of the plates 14. This pawl has an extension 31 in the rear of its pivot, that bears on its rear side against a pin 32, projecting upwardly from the face of the short arm of the bell-crank lever. The throw of this pawl is varied by an arm 33, pivoted to the bell-crank lever in proximity to the end 31, having a lateral extension adapted to be moved to or from the end 31. The pawl engages and follows the toothed wheel when the bell-crank lever is tilted until the end 31' strikes the arm 33, when said pawl is locked and prevented from moving further. When the lateral extension is moved away from the end 31', the pawl is enabled to follow the toothed wheel until thrown out by said end4 3l striking the side of said lateral extension and the greatest amount of movement is given the platen; but when the end 31 strikes the end of the lateral extension the pawl is thrown out earlier than in the former case and the movement of the platen is lessened. Pins 34 35 project up from the short arm of the bellcrank lever on opposite sides of the arm 33 to limit the movement thereof. The long arm of the bell-crank lever is given a quarter-turn and fiattened near its end to present a iin gerpiece 36, that may be readily grasped. A spiral spring 37 is provided to normally hold the bell-crank lever retracted and the pawl carried thereby out of engagement with the toothed wheel.

The platen is held in position when moved by an elastic roller bearing on the toothed wheel,this rollerbeing journaled in the forked end of an arm 38, journaled on a rod 39, extending between the rear ends of the plates 14. A spring 40 is coiled around said rod and secured at one end to the arm 39 to hold the roller against the toothed wheel.

Paper-guide clips 41 are arranged along the platen, these clips being pressed into engagement bythe flat springs 41', secured to the rod 31 at one end and pivotally connected at their opposite ends to ears bent out of the intermediate part of the clip. This intermediate connection and pressure of the springs insures an even pressure of the clips from end to end of the platen.

The frictional paper-roll 42 is journaled in the ends of arms 43, pivotally connected to the plates 14 and held into contact with the platen by light spiral springs 44, interposed between the arms and plates. The papersupport is formed in two parts, one part, 45,

IOO

being fixed to the rod 39 and the other part, 46, being pivoted to the top of the rear bar ot' the carriage.

Short vertical standards 47, extending upward from the top of the frame l in rear ot' the rear track 2, support the rack-bar 48, which is fixed to a rock-shaft 49 by extensions 49 of the collars 54, said bar running longitudinally of the frame parallel to the track. Both edges of this rack are toothed, the apices of the teeth on the edge nearest to said track being beveled off in a direction opposite to the main bevel of the teeth, thus forming reversely-beveled teeth. To the upper face of the rear bar of the carriage, intermediately thereof, a plate 50 is secured, which extends ont over and beyond the rack. A pawl 5l is pivoted to the under side of this plate, near its outer edge, this pawl having a beveled end, which is held into engagement with the teeth on the rear edge of the rack-bar by a spiral spring 52, connected at one end to a pin projecting from the edge ot' said plate 50 and at its other end to a pin 5l', projecting from the upper side of said beveled end, the inward movement of said end being limited by a pin 50', depending from the plate 50. A stationary pawl 53 is screwed to the under side of the plate 50 on the opposite side of the rack-bar, and this pawl is adapted to engage with the reverselybeveled tooth when the bar is rocked in that direction, which occurs on every depression of a key.

Each of the collars 54 is fixed to the rockshaft 49 and has a laterally-extending arm 55, and to one of these arms a link 56 is connected, the opposite end of which is secured in a cross-bar 57 extending beneath the key-bar. On every depression of a key the key-bar depresses this cross-bar, which draws down on the arm 55 and rocks shaft 49. This draws the toothed bar out of engagement with the pawl 5l and allows the carriage to slip forward one step, the stationary pawl riding over the reverse bevel on the tooth and engaging therewith. Thus as soon as the escapement begins to take'place the pull of the carriage forces the rack-bar onto the pawl 5l, which has a slight adjustment. The carriage is drawn forward by a spiral spring incased in and connected at one end to a drum 56, which it tends to rotate rearwardly, a strap 57 being connected at one of its ends to the periphery of this drum and at its opposite end to a lug 58, depending from the plate 50. To move the carriage forward independently of the key-levers, a lever 59 is pivoted to a bracket GO, projecting from the rear bar of the carriage, this lever having a laterally-bent cam-shaped end, which rides against the pin 5l and pushes the pawl 5l out ot' engagement with the rack-bar when the arm 60, pivot-ally connected to the opposite end ot the lever 59, is drawn forward.

The arm 60 is held to the upper face of the end bar of the carriage by headed screws 6l,

vstandard of the frame l.

tixed in said end and extending through slots in the arm into said bar. The ends of these arms are turned upwardlyto present projectio"ns that can `-'be easily engaged by the iinger to shiftthe same. A central opening is made in the top of the frame l, around which the hangers 6 are arranged, being held in place by a ring 6l', that rests on the upper edges thereof, bolts 62 extending throughl the ring and between the sides of the hangers into the top of the frame to secure the hangers in place. Each hanger comprises two side plates held together by a pivot 63, extending through the center of the same. A hole is made in each plate near the rear end, and one hole in each pair of plates is threaded to receive the threaded end of a bolt 64, having its opposite end held against transverse movement on the opposite side plate and a suitable opening made in its body to permit of the insertion of a tool for turning the same. Each plate is provided with a forward extension of reduced width, and when placed in position the reduced extensions of one pair are arranged in staggered relation to those of the next pair. ln the ends of these extensions conical openings are made to receive the ends or" the pivot-pins G5 of the type-bars GG. These pins are journaled in each pair of plates, the ends being conical to correspond to the opening. The conical sockets are pressed onto or off of the ends of pin 65 by turning the bolt G4, which will force the rear ends of the pair of side plates apart or draw them together, according to the amount and direction of the movement given said bolt. This provides means for effectually taking up VWear on the pivot-pins and hangers. The type-bars are connected to the key-levers 66 by a link which is formed in two parts, the upper part 67 being a wire rod and the lower part 68 being formed of sheet metal and being connected to the parts 67 and key-lever in a novel manner, as will be described hereinafter. The key-levers 66 are supported by spiral springs 69, connected to the intermediate part ot' the key-levers at one of their ends and at their opposite ends to the turnedin edge of the plate 70, secured to the rear These levers have V-shaped notches on their rear ends, into which extends the edge of plate 7l, on which said levers are pivoted. The vertical ends of the levers whichv carry the keys have their lower portion split centrally, the two parts thus formed embracing opposite sides of the horizontal portion. these two parts extend below the said horizontal part and are bent nparound the same to embrace the opposite side thereof. The lower parts (3S of the links are all pivotally connected to thesame point on all the key-levers. This gives each ot' the key-levers exactly the same dipthat is to say, they all require the same pressure on the keys to depress the same. To accomplish this result, it necessitated a peculiar form and The extreme ends ot,

IOO

IIO

arrangement of connecting-link, and we have devised the form shown herein. This consists of a sheet-metal plate having a lower extension that is bent at its lower end to embrace opposite sides of the key-lever to which it is pivoted, a body portion 68, and a lateral extension 70, the extreme end of which is pivotally connected to the section 67 of the link, an elongated opening 71 extending between the lateral extension and the upper part of the body portion. This upper part is compressed to forma cylindrical extension 7 2, that slides in an openingin the face of a guidebar 7 3, extending across the machine and supported in brackets depending from each side of the ring 74, supported from the top of the frame 1 by arms 75. The lateral extensions are arranged in pairs and extend alternately on each side of the guide-bar 73. The extensions near each end of the guide-bar 7 3 are shortened as they connect with the type-bars at the sides of the machine. The plates that connect with the type-bars directly at the sides of the machine are given a right-angular bend, as shown at 75, and the extension thereof extends parallel to the guide-bar. The extensions of the two end pairs of plates pass through the openings 71 in the succeeding pairs. ln the present case there are two pains of these angularly-bent plates at each side of the machine.

The upper-case key 7G is connected by a link 77 to the arm 78, extending from the collar 79, fixed to the shaft S0, that is journaled on the short vertical standards S1, extending from the top of the frame 1. This shaft has two integral teeth or ribs extending along its full length,Which mesh with the teeth 82, projecting from the collar 83, xed to the rod 1S. It will thus be seen that each depression of the upper-case lever will depress the arm 7 S and rock the shaft SO rearwardly and the collar 83 and rod 18 in an opposite direction, thus throwing the links 17 and arms 16, pivotally connected thereto, forwardly, and as the opposite ends of said arms are connected to the shaft of the platen said platen will also be drawn forwardly. A supplemental key S4 is provided for depressing the upper-case key, and a plate S5, secured to the side standard of the frame 1, has a slit therein, in which this key-lever is guided. A shoulder or offset 86 is made in this plate, beneath which the key-lever is pressed to hold the same depressed when several upper-case characters are to be printed in succession. The supplemental key has a plate S7 riveted thereto, and the end of this plate has a fiat horizontal extension overlapping the upper-case key-lever, so that while the upper-case key may be operated independently of the supplemental key the supplemental key will necessarily operate the upper-case key whenever it is itself perated.

e ribbon-spools 88 are carried on a shaft burnaled in the side standards of the `his shaft has a part thereof flattened, and the bearing in the spool is correspondingl y flattened, so that while the spool may be shifted longitudinally of the shaft it can have no independent rotary movement. The ribbon is shifted transversely of the ribbon-guides 00 (these guides not being shown in Fig. 1) by forked arms 91, carried by a rock-shaft 02, journaled in the sides of the frame 1, the forks engaging the grooved collars 03, fixed to said ribbon-spool. A knob 2 extends from one of said arms to provide means for shifting the same.

The shafts 30 carry bevel-gears 94C, which are adapted to mesh with either of the gears 95, carried on opposite ends of the shiftable shaft 9G, to first cause one of the spools to wind up the ribbon and then the opposite one. This shaft 9o' is rotated by a pinion fixed thereto, which is moved by a pawl 07, pivotally connected to the arm 55 of the collar 54, before mentioned, which is fixed to the rockshaft 49 and is operated on every depression of a key. The shaft 9G is shifted by means of the shaft 97', having a forked plate 98 secured thereto, a collar 99 on the shaft 97resting in said fork.

To indicate to the operator when the end of the ribbon has been reached, a semaphore 98 is arranged at each side of the machine. These semaphores are rigidly fixed to the ends of the shafts 90, journaled in the side standards of the frame 1, from which wire loops 100 extend inwardly. The ribbon passes be tween the shaft 00 and the loop 100. The ribbon is secured to the tape that is permanently fixed to the spools in such a manner that the end of the tape of either spool will strike and raise said loop on the side nearest thereto when the ribbon has become wholly unwound from its spool, thus raising the semaphore on that side. The bell 101 for indicating when the side of the paper is reached is secured to an arm 102, which has the hammer-arm 103 intermediately pivoted to the end of the same. This hammer is operated by a hanger 10i, pivoted to a disk 105, journaled on the shaft of the drum 5G and adjustably held thereto by a thu mb-nut 106, extending through an arc-shaped slot in said disk into the face of said drum. The hanger 10-/1 has a weighted beveled laterally-extending end that engages with the upper end of the hammer-arm as the drum rotates and tilts the same and then releases it and the drum continues to rotate, the weight of the ham mer on the end of said arm causing it to then swing against the bell and ring.

le have provided means for regulating the return of the carriage after it has been fed forward, and thereby the width of the margin that is left along the edgeof the paper. This consists of a pawl 107, pivoted in a recess in the rear face of the front bar of the carriage, that is adapted to engage with one of a series of teeth 108, made in the faceof the front track 2. This pawl drops into the first tooth it engages, and the further return movement IIO of the carriage is then prevented. To vary this movement', a Plate 109 is provided which" slides on the upper face of the track 2 and is designed to cover any number of these teeth. This plate is adjustable and is held in place by a thu mb-screw 110, which extends through a lateral part thereof into a groove in the beveled face of the front track 2.

The type-bars while of an ordinary general shape are of novel construction. Ve make these of pressed metal, and the-body of the bar and the socket for the type-shank are of one piece. The stem of this bar is made tubular by pressing the longitudinal edges thereof together, and the rear end thereof is forked, the end of each fork extending at an angle to the main body of the bar. v

A modification of the paper-clip is shown in Figs. 20 and 2l. This clip has an elongated boss c at the central portion thereof, over which a socket formed by pressing a corresponding boss out of the spring 4l iits. A rivet extends through these bosses and secures the parts together. A short cylinder d, adjustable on the bar 3l and having a rectangular slot to receive the same, carries a tube e, which is encircled by the curved end of the spring 42a. A screw extends through this spring and through the tube e into the cylinder cl to hold the parts together. A handle g is provided for shifting these parts, this handle having a shank which also projects through the tube and into the cylinder CZ. These connections are made in duplicate, and only two clips are used, one being placed near each end of the bar 31. In addressing envelops or the like either one or the other of the clips can be moved toward the center, suitable stop-pins being preferably projected from the rod-3l to limit the movement thereof. The advantage of this arrangement is that if there are a number of cards or the like to be addressed it is not necessary to make a separate adjustment for each card.

In Figs. 16 to 19 a modification is shown of the type-bar and pivoted pin. In this form alining openings are made in the forked ends of the type-bars, into which a shouldered bushing is fitted, the ends thereof projecting out beyond the sides of the forks and being upset to force the metal onto the forks to clamp and securely lock the same together. The pivoted pin extends through and is held in this bushing, and the metal of the bushing is also forced against the pin to hold it against displacement when its ends are upset. The angularly-extending parts of the forked ends are brought together, as shown at b, and an opening made therein to receive the hooked end of the link 67.
