Fig. 13 is a detail View of a pawl. Fig.14C is a section alongline 7, Fig. 5. Fig. 15 is a section along line 8, Fig. 14C.

In the drawings, the letter A indicates a frame or support, and B is a platen or papercarrier. Each type-bar C is shown as having three types, and when the parts are in position shown in Fig. 6 the outermost type of a bar is in position to print on the paper supported by the platen or roller B. NVhen the parts are in the position shown in Fig. 7, the central type is in position to print, and in Fig. S the innermost type is in position to print.

Of course I do not limit myself to three types on a bar, as this number may be varied, it being evident that the. machine would work, for example, with but one type on each bar. The hammer D forces the type-bar toward the. platen or roller B, so as to cause a type on said bar to print. Motion is conveyed to a type-bar from a key E by a suitable mechanism, which will be now described.

The key E is jointed or pivoted at F, Fig. 5, to a lever G, fulcrum ed at a rim H, extend- 5o ing from a post I on frame A. AThe arm K of bell-crank lever K L is connected to the lever G by a pin-and-slot connection M N, Fig. 2. A link O is jointed or pivoted at Pto the leverarm L. The link O passes through an eye Q on the type-bar C. Said link has a shoulder or recess R, and when the parts are in the position shown in Figs. 3, 4.-, and 5 the recess R is in engagement with the rim of eye Q. When the key E is depressed, the levers G and K L are oscillated, so as to move the link 6o O and type-bar C toward the platen or paper-carrier B. The free end of link R is inclined, and when the shifts S T are in the position shown in Figs. 5 and 6, the link R, after having moved toward the platen a sufficient distance, will have its incline riding along shift S, whereby the link R is swung about pivot P sufficiently to lift its recess R out of engagement with the eye Q. The link R then continues its motion toward the platen, 7o while the type-bar is left stationary with its outermost type in position to print, Fig. 6. WVhen the shift S is raised, Fig. 7, the link O is not lifted out of engagement with eye Q until the type-bar has been moved a sufficient distance to bring its central type in position to print, while if both shifts S T are raised, Fig. 8, the link() is not moved out of engagement with eye Q until the innermost type is in position to print. When the shift S is raised, 8o the link O passes under said shift, so as to cause its incline to ride along shift T, while if both shifts S T are raised the inclined end of link O rides along the rim U, said link in last-named case passing under both shifts S T. The arrangement for operating the shifts will be presently described. Y

When the type-bar is in its printing position, as in Figs. 6, 7, or 8, itis held in said position by a suitable lock or locking mechan- 9o ism consisting of lugs or stops V on the typebar and of a detent W, engaging said lugs. Said detent W is connected to the lever-arm X, extending from bell-crank lever K L. As the key E is depressed and the lever-arms K L X are oscillated the detent W is moved toward the type-bar, so as to enter'the space between two lugs V and lock the type-bar in position. Vhen the type-bar is in the position shown in Fig. 6, said bar is locked by the deroo tent W entering between the innermost lugs V, while in Fig. S the detent IV enters the space between the outermost lugs. As the type-bar has to move a greater distance to reach the position shown in Fig. S than that shown in Fig. t3, the lugs V are varied in length,said lugs becoming shorter from the innermost one outward. By this shortening of the lugs the type-bar is enabled to reach the required printing position before the dctent XV enters between the required lugs V to lock said bar. The lever-arms K L X are fulcrumed at Y to a post Z, rising from the frame A. The various type-bars, cach having its respective key, can be arranged in any suitable series to be convenient for the operator.

The shift S is operated by key a, and the shift T by key Z). The key ais connected to alever c, fulerumed at d, and the key b to a lever e, also fulcrumed at (Z. Lever c is conneeted by a link f with shift S, and a link g connects lever e with shift T. From shift S extends an arm or shoulder h, Figs. 5 and 7, over shift T. lVhen the key a is depressed the lever c and link f are actuated to raise shift S, Fig. 7. \Vhen key Z) is depressed, the level' e and link g are actuated to raise shift T, Fig. S, and said shift T in its ascent carries with it the shoulder hand shift S, so that the depression of key ZJ raises both shifts S and T. Zhen the keys a and l) are released, the weight of the shifts will restore the parts to their starting-point; but if this weight is not suilicient suitable restoring-springs (not shown) may be applied in any suitable well known way.

The hammer D is actuated as follows: Said hammer is held in its free or inactive position by a spring 2'., Fig. 5, said hammer being mounted on a pivot or turning point Z3. A link Z has a shoulder m, Fig. and when said link Z is depressed the shoulder m draws the hammer toward the platen. Said link is secured to the universal bar n, and when said bar yn is depressed by the action of a lever G and key E said bar vn draws down the link Z and the hammer D is brought into action. On releasing the parts the spring t' restores the hammerD to its starting-point. The universal bar n is carried by arms o, extending from the rod p, which is journaled in posts q, rising from frame A. The bar n and arms 0 arejointed or connected to oueanother at r, Fig. 5. A link s, Fig. 5, is jointed or pivoted at t to the link Z and at a to a post o, extending from the frame A. A spring flu is oonnected to said link s, and when the key E is released the spring w restores the link Z, lever G, and key E to the starting position. The link Zin rising to its starting-point draws up the universal bar 91,. The return of the le Ver G to its starting-point also restores the type-bar C to its starting position. The bar C has a shoulder x, and as the lever-arm L and lilik O are moved by the lever G on its returnto their starting position said link 0 strikes against the returning shoulder a; and moves the type-bar C back to its startingpoint. A stop or stop-rim 9/ prevents the type-bars C from moving too far back, and said stop Iy may be padded or provided with rubber rings or cushions to take up the jar of the returning type-bar.

A lever A is jointed or pivoted at B to the link Z, and as said link rises and falls said lever A is oseillated about the fulcrum C. Au arm or pawl D is jointed or pivoted at E to lever A andthe free end of said arm D is guided by a pin-and-slot guide F G', Figs. ll and 12. A link Il connects the arm D with arm or pawl I', having its turningpoint at K. Said arms D I have each a tooth engaging an esoapement-wheel L. The arms D L form an escapement for the wheel L', and as the lever A moves the arms or pawls D l from the position shown in Fig. ll to that shown in Fig. 12 and then back to that shown in Fig. ll the escapement-whccl L moves one tooth in the direction of the arrow, Figs. 2 and l2. By this motion of the escapeinent-wheel the platen B is fed along, as will be presently explained.

The csoapement-wheel is mounted loosely on the shaft M. To said shaft is secured one end of a spring N', Fig. ll, the other end of said spring being secured to a fixed drum or box O. The spring N tends to drive the shaft M ip the direction of the arrow, Fig. l2. The motion of the shaft M in the direction of said arrow is communicated to the escapement-whcel by a clutch consisting of a ratchet P and a pawlQ. The ratchet P is fixed to shaft M and the pawl Q is mounted or pivoted on the escapement-wheel L. A spring R presses the pawl into engagement with ratchet P. Said spring is braced against stud S, Fig. 12, rising from the-escaperncntwheel L. To the shaft Mis secured a toothed wheel T', gearing into the eedrack U of the platen B. As the escapement-wheel L, shaft M', and gear T rotate in the direction of the arrow, Figs. 2 and 12, the platen B is fed along. lVhen the platen B is to be set back it need, only be pushed toward its starting-point, since the pawl Q allows the ratchet P and shaft M to turn in the direction opposed to the arrow, Fig. l2, while the escapement-wheel L is at rest, the pawl in this last-named case riding over the ratchet.

The platen B is mounted or journaled in a frame or carriage V, having guide-arms W', provided with eyes through which passes the bar X, along which the platen-carriage moves back and forth. The arms lV may have a bar Y at their lower end to steady the platen and its carriage.

The pawl Q can be thrown out of engagement whenever desired by the rim or releasing-ring Z, sitting about shaft M. The pawl Q has an inclined face or part ct, and when the releasing rim Z is pressed toward the pawl said inclined face a rides outward on the rim Z and the pawl is disengaged from the ratchet, so that the clutch mechanism formed by the ratchet and pawl is thrown out of action. The rim Z is actuated by the le- IOO IIO

v the pawl Q ver b', fulcrumed at c,`Fig. 14, and said lever b' is engaged by the arm d' of bell-crank lever d' e' fulcrumed at f'. The bell-crank lever d' e is shown plainly in Fig. 15, and the arm d', abutting against lever h', so that when the arm c is depressed by the key g' the arm d' moves the lever b so as to throw the rim Z against the inclined face a', Figs. 10 and 13, of pawl Q', and then lift the pawl to its releasing position. The arm e is connected to the key g', and when said key is depressed the lever c is moved so as to carry the rim Z against the pawl Q. When the key g' is released, the spring h Figs. 5 and 12, throws the rim Z' away from pawl Q', so that the spring R' can again throw the pawlinto gear with ratchet P'. y The purpose of throwing out of engagement is to thereby release the ratchet P and shaft M', so that the platen can freely or'rapidly slide or move forward to any desired point at which the writing on a certain line is to commence.

The spacing-key ol', Fig. 5, is jointed at 71;' to lever l', fulcrumed at m'. Said lever is shown composed of two parts or duplicates, Fig. 1 carrying rod n', and as the key t" and lever 4Z' are depressed the rod 'n' depresses links s and Z, so as to actuate the lever A', whereby the platen B is caused to move. When the spacing-key is released, the restoring-spring o',pressing against rod p', returns the key to the starting-point.

The platen B supports the paper q', as seen in Fig. 5, a presser-bar r holding the paper down on top of platen. The bar r' is carried by a frame s', Fig. 1,-journaled at t' to the platen-carriage V', and a spring w', secured to the axle t and braced against a stud c', presses the frame s and ybar r' down on the paper q. In addition to the restoring-spring ma restoring-spring 0c,Fg. 5, can be secured to each lever G, and the spacing-key t" may also have a restoring-spring y'.

In order to protect the parts as much as possible, covering-plates a', Fig. 5, may be applied, which can be removed whenever required, so as to allow cleaning and repairing.

The types on the bars C are inked by being carried past the ink-rollers w' as said bars slide back and forth.

The ink-roller can be variously located. I have found a convenient arrangement to be that shown in Fig. 1, where one ink-roller is placed parallel to the platen and two other rollers are placed at angles to the first roller, so that the several rollers correspond as nearly as possible with the radiating directions of the type-bars.

The type-bar is constructed of elastic material or its type-carrying portion is made elastic, so that the hammer D, as seen in Figs. G to 8, can press the bar against its elasticity for printing with a type. As the type-bar receives its motion from link O and the hainmer D receives its motion from an independent mechanism-namely, the link Z-the motions of the type-bar and hammer can be readthe detent.

ily timed to take place at the proper instant with respect to one another. As the levers G lie equally across the universal bar and as said levers are equally actuated by their keys, the connection between the keys and the universal bar is such that the universal bar is equally moved by the keys, and the action of the hammer is thus uniform for all the keys and type-bars. By arranging the levers G radially, as shown,a compact structure can be obtained occupying but little space.

It will be noticed that the link O, by its engagement of the eye Q and shoulder @c of the type-bar, moves said type-bar positively in both directions, so that a positive connection is formed between the key and the type-bar by means of the link and levers G K L. The lever-arms K L X may be considered as forming a three-armed bell-crank lever actuating the link O and detent W, so as to form a positive connection between the key, the link, and The detent, it is noticed, is moved at all times the same distance whenever the key is depressed irrespective of whether the type-bar moves a greater or less distance. The movement of the link O and type-bar C being a sliding movement, said bar is easily actuated, since it does not have to be raised or moved against its own weight. The typebars C radiate toward a common point and the ink-rollers are inclined toward one another, so that the various type-bars can readily slide past the respective ink-rollers, said ink-rollers being placed in the paths of the type-bars to ink the type.

The hammer D, being made to press `from above down onto the type-bar, is in position to exert considerable force, and as the printing is done along the top of the platen the printing as it progresses is constantly visible to the operator, the platen-carriage V being open at its top. v

When a key E has been depressed and the escapement mechanism has been moved to the position shown in Fig. 12, the spring N' tends to rotate the escapement-wheel so as to force the parts back to the position shown in Fig.v 11, and this tension of spring N' is transmitted through lever A to the universal bar and thence to the key E, so that the actuating-spring N' at the same time acts as a restoring-spring for the key E. Vhen a key E is depressed, the lever G is depressed so as to depress the universal bar n and move the lever A' to carry the pawl D' to the position shown in Fig. 12 and the tension of the spring N causes the escapement-wheel L' on its respective tooth to press on the pawl D', so as to return said pawl with the levers A G and key E to the starting-point, so that the spring N', in addition to its other functions, operates to return the keys to the starting-point when said keys are released by the operator.
