TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 407,185, dated July 16, 1889.

Application filed January 24, 1887. Serial No. 225,408. (No model.)

To all 107mm it may concern.-

Be it known that I, WILLIAM HEINRICH ELLING, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Type-lVriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in type-writing machines, and has for its object the construction of an improved machine in which are embodied the following distinctive capabilities: first, printing directly from the type without the use of intermediate tape or the like; second, printing on an exposed surface, so that the operator can read the printin gas it occurs letter after letter; third, printing on plain sheets of paper, as in books, with varying thicknesses and unequal sides.

The invention consists in mechanism where by these results and others of less importance may be attained, all as shown and described, and particularly pointed out in the claims.

In the accom 'mnying drawings, Figure 1 is a perspective view of my improved machine; Fig. 2, a plan view thereof. Fig. 3 is a perspective view of a horizontal sect-ion of the machine, disclosing the lower part thereof with the carriages and their actuating mech anism. Fig. i is a cross section of the ma chine with certain parts omitted and designed to show the type-arms in different positions and the mechanism for raising and lowering the table which supports the paper in printing. Fig. 5 shows a type-arm in three positions and a section of the inking mechanism, and Fig. (3 is a detail of a type-hammer. Fig. 7 shows the escapement mechanism, and Fig. 8 a plan of the arrangement of certain other key-levers, as hereinafter more fully explained. Fig. 9 is a view of the lower end of the type-arm with the associated parts. Fig. 10 is an enlarged view of a bell-crank lever and its spring for controlling the type-arm. Figs. 11 and 12 are details of the drum and pinion connected with the inking-carriage.-

The machine is built in a double-deck frame 2 3, the upper part 3 being'supported on posts 4. at the front and side, as seen in Fig. 1. EX- tending across the part 3 back of the keys is a plate 5, having a circular opening 6 therein, also as seen in Fig. 1. This plate may be integral with the frame or a separate part fixed thereto, but is a firm and fixed member and forms a support for other mechanism.

The printing is done in or through the opening 6 by the type-arms arranged longitudinally and concentrically around said opening in the plate 5. In said plate I cut a series of radial slots 8 and concentric slots 9, and in these slots are adjustably secured standards 10. Each standard has at its head a right-angled foot 11, with slot and setrscrew 12 from below the supporting-plate through slot 8 for adjustment back and forth. These screws hold the standard 10 firmly when fixed and serve to bring all the type-arms 13 into position for alignment and the like.

The typearms are pivoted to the standards 10 on pivot-pin 14, and each has at its lower end a broad heel 15, which slides upon the surface of the standard and insures the alignment of the arm. The keeper 16 serves also as a guide to the up and down movements of the arm in conjunction with guide-lip 18, attached to the arm so as to reach over and bear against the side of the standard 10, as plainly seen in Fig. 5. This mechanism insures accuracy and uniformity in the stroke of the type-arm.

The ty 'ie-hammer 19 is pivoted near the top of the arm 13, Fig. 5, at pivot 20, and has a cavity at one end to hold the type. In front of the pivot-point 20 in arm 13 is a longitudinal curved slot 22, and in the hammer is a straight slot A rod 2i, pivoted on the inner extremity of standard 10, has its upper end bent and passed first through slot 22 and then through slot 23, and its end bent at right angles keeps the rod in its place and close fitting to the drum, yet leaving room to operate. Then upon the upper end of the arm I fix a plate 25, which is screwed on the arm at 27 through a small spacing-washer 28, and is held below by the pivot-pin of the type-hammer and an overhanging lip 29. The forward of the slot. 22.

the arm is in its normal position the typehammer is reversed, as in full lines, Fig. 5. When partly lowered, it is as seen in first dotted position, and when down and striking to make impression as seen in second dotted position.

The arms 13 are operated by levers 30, provided with keys 31 at the front of the machine. Owing to the peculiar construction of my machine I require intermediate mechanism between the key-levers and the type-arms to effectuate the strokes, and this varies somewhat according to the position of the levers and their respective arms, which also are either differently bent or are arranged to work vertically or rotate according to position. I attach no importance to this intermediate mechanism or construction, and any form or forms that will do the work may be adopted. In what is shown I have bent the key-levers in such manner as to best get back to their operating position, and so that they can play vertically and make connection through links 32 at their inner ends with bell-crank levers 33. These levers in turn are connected by links 34 with the type-arms a short distance above their pivot-points. The bell-crank 1evers 33 are pivoted in shoes 35, fastened to the base-plate 5, and retractingsprings 36 in the shoes 35 are attached to the said levers to withdraw the type-arms after each stroke. In case the type-arms are located well to the rear of the machine, as in the case of at least two on either side, (shown in Figs. 1 and 2,) a double system of levers may be needed. WVhen this occurs, the long rods 37 shown would be arranged to rock, and the key-lever proper would engage with their bent ends, say, through bell-crank or equivalent means.

On the lower portion of the main frame are the carriages for supporting land conveying the paper or book to be printed. Of these carriages there are two supported on a sliding or movable. frame 38, which is held in transverse guides 39 in the main frame, and serves to convey the two superposed carriages bodily to one side of the machine by drawing said frame 38 laterally in its guides, thus making the carriages accessible to the operator. Finally, however, when the machine is at work, the frame 38 will be pushed in and rest within the main frame, substantially as seen in Fig. 1. This frame 38 itself has transverse guides, as 40, and anti-friction wheels, as 41, to guide and carry the letterspacing carriage 42. By drawing the frame 38 out, say, half-way, and then drawing out the letter-spacing carriage half-way, or thereabout, in its guides on said frames, the two carriages are brought wholly outside the main frame. Along the front edge of this carriage 42 is a rack-bar or plate 43, spaced so that each tooth will represent the space between the letters, and meshing with this bar is a pinion 44, supported on a sleeve on a shaft 45 extending to the front of the machine beneath the keys. It is designed that with each downward pressure of akey and its corresponding lever a single impulse shall be imparted to the letter spacing carriage through the said rack and pinion and the impelling spring and pawl for carriages. To effect this many difierent kinds of devices may be e1nployed,and it is not particular what kind is used. In this case I employ a rod 46 beneath each series of the keys, which rod has its ends bent at right angles and pivoted midway of the bends on the sides of the main frame. At the extremities of said ends at one side are links 47, Fig. 7,which connect with ends of the pivoted arms 48. These arms extend over and across the end of a lever 49, pivoted at its opposite extremity to a plate 50, attached to the main frame; also supported on posts or bearings fixed in the main frame is a toothed wheel 51. At their other ends the rods 46 are bent twice at right angles, as" seen in Fig. '7, so as to bring the end back parallel to the body part. To the extremity of each end of these rods thus bent is a pivoted and slotted arm 52, which engages a rock-bar 53 in its closed slot, said bar being bent to give it a rocking bearing at 54, and have its near end bearing againsta shoe 56 on spring-pressed post 57 The shoe 56 is pivoted on the said post and has a flanged portion above the pivot which bears against the edge of the post, so that when the end of the bar 53 has been rocked past the top of the shoe the said end will drop behind the flange thereon and pe'rmitthe spring-pressing post 57 to force said post forward. Two such posts and rock-bars are here shown, with each of which two of the series of keylevers connect through the cross-rods 46.

Connected with the tops of posts 57 are rods 59, supported pivotally about midway on rods 60, and having their outer extremities bent at right angles to press against the upper arm of bell-crank lever 61 when either rod is moved inward as in operation. This bell-crank lever engages a pawl 62 in a slot therein and supported with said lever on the pivoted plate 63. Said plate normallyis carriedforward by a spring 64 and link 65, connecting with the bell-crank lever thereon, and rests with its edge against the edge of the post 50 on the main frame, which spring and link also hold the pawl in engagement when the pivoted plate is forward.

On post 50 is a spring 66, which extends beneath and supports the lever 49, and on this plate, also, is another-pawl 67, which engages the teeth on wheel 51 at proper times, and on the lever 40 is a pivoted spring-pressed arm 68, which has a shoulder 69. This shoulder comes into engagement with pin on pawl 67.

The operation of these parts is as follows: WVhen a key-lever is pressed down, it bears upon the cross-rod 46, which is held up against said levers by counter-spring7 1,and through arm 52 and the chain of mechanism extending to pawl 62 lifts said pawl and carries the pivoted plate to which it is attached back as far as the rock shaft or bar 53 can force it. In the meantime the lever 49 is depressed by pivoted arm 4:8 at the other end, and the shoulder of the spring-pressed arm 68 is permitted to come in underneath the pin of the pawl ('37. Before, however, the key-levers are depressed to their limit of mot-ion downward, the end of the rock-shaft 53 will have risen above the shoe-flange 56 and dropped behind said shoe-flange, which now permits spring-pressed post 57 to fall back, when the spring 64c will pull both on the elbow-lever 61 and the pivoted plate 63. Then it is that the dog 7 2 on said plate will engage a tooth on wheel 51, preventing the return of the pivoted plate unless the wheel moves with it. At the same moment that the dog comes into engagement with a tooth the elbow-lever also forces the pawl 62 down in front of a tooth on the wheel, and the pivoted plate is now locked to the wheel 51. Then, again, instantly as pressure is taken off the key-levers and the arms &8, the lever l9 will rise and bring the shoulder of the spring-pressed arm 68 into engagement with the pin 70 ot' the pawl 67, lifting the pawl out of engagement with the toothed wheel. It is now that the coil-spring drum 7 a will pull the letter-spacing carriage l2 forward as far as the escape ment-wheel 51 will allowsay one to three teeth, according to the distance the pivoted plate 63 has been set back. As this is done, a stud 73 on the front edge of the pivoted plate 63 strikes the top of the arm 68 and carries it back to release the pawl 67, when said pawl drops into engagement with the teeth of the wheel 51 preparatory for the next movement. Both pawls are then down and remain so till another key is struck and the parts are thrown first of all into position, as seen in Fig. 7. In this manner a forward movement is imparted to the spacing-carriage with each depression of a key-lever.

On the lower carriage isa coil-spring drum 71, which has a cable 7 5, connecting with the letter-spacing carriage to draw said carriage forward after it has been drawn back by hand, thereby winding up the spring ready to pull the carriage for letter-spacing the instant the escapement-wheel 51 permits it during the printing of aline. Then to produce the linespacing I employ a carriage 76, which moves in suitable guideways 77, Figs. 3 and 4. A hand-lever 78 has a pawl 79 attached to a short arm thereon, which engages ratchet-teeth .80, whereby the said carriage is moved forward the required distance; but, as I stated at the outset, I have means to print on matter of varying thickness and evenness, for which purpose I employ a vertieally-adjustable sectional table 81. The leaves of the table 81 are each separately attached to the arms 82 of a yoke supported in posts 83 on said carriage. At the rear end the yoke has a downward-projectin g arm 84, to the lower end of which a link 85 connects it with the system of levers beneath and controlled by the single hand-lever 80. The arms 82 are pivotally attached to cars 87 centrally beneath the ends of the leaves of the table. Rods 88, connecting below the ends of the yoke with said ears, extend outward and engage the posts 83 below the ends of the yoke, so that thereby a parallel'moving mechanism is prod need which causes the table-leaves to rise evenly and horizontally.

The mechanism beneath the table for raising the leaves is exactly the same on both sides, each yoke-arm S2 at the rear end of the yoke engaging through link 85 with a lever 89, pivoted in a cross-bar of the main frame, and at its other end bylink 90 with an evener 91, pivoted centrally on the curved inner end of hand-lever S6. Ordinarily the pull through the hand-lever and evener will be even on both sides and raise the two leaves together; but it is obvious that if pressure be brought on one side or leaf of the table the evener will yield on the opposite side when the lever is worked to raise it, so that one leaf may be carried up to the highest working-level while the opposite leaf is down. Then when the first leaf has been elevated the full height, say against the leveling- bars 92 and 93, and the hand-lever is carried still farther over, the other leaf will be raised to the same level or any desired intermediate level. In this manner an open book may be laid on the table and the great bulk of leaves rest upon either side, and yet be brought flush up on both sides to a common level beneath the levcling-bars. The bar 92 is vertically adjustable on standards on the letter-spacing carriage, and the bar 93 is adjustable and free to swing on its pivots supported on the linespacing carriage, both said bars being adjustable to come up in their entire length to adjust them to the general impression-point to which the type-hammers have been set.

The sheet of paper, or whatever is printed upon, is brought up against the leveling-bars for support, and feeds along beneath the bar 92 as the top carriage is moved back line by line. The cross'bar 92, carried by the linespaeing carriage, is adjustable back and forth on the rods on which it is supported on the sides of said carriage, and is designed to hold down the paper or leaf on which printing is being done. \Vithout this bar or its equivalent the end of a sheet of paper would be liable to curl or turn up. The adjustment adapts it to sheets or books of different lengths.

It has been observed that when the type arms and hammers are at rest the type-hammer is in inverted position and the type-faces to the rear. This enables me to ink the type by providing an inking-cushion 91 for this purpose. This cushion, of course, is circular,

and is fixed on a circular carriage 95, supported by anti-friction rollers Do on a track frame 97, resting upon suitable supports on the bed-plate of the upper frame. A plate IOO its way to avoid friction.

95, preferably made in two or more sections, is secured by screws to the track-frame and extends over the inking-carriage flush with its inner surface, but is apart from the same, so as to give the carriage free movement. By removing this plate the carriage maybe removed for any purpose. In order that the inking-carriage may do its work well, the cushion-carriage is rotated when the machine is at work, and ink-distributing rolls 99 atintervals help to spread and even the ink on the cushion.

Any suitable means for rotating the carriage may be employed. In this instance I show a toothed rack 100 on the lower edge of the carriage 95, which is engaged by a pinion 101 on a shaft carrying a coil-spring retracting-drum 102. Over this drum, Fig. 1, extends a cord 103, which can be traced by the eye to the front and side of the machine, Where itis attached to the end of a horizontally-operating lever 104, Fig. 3, passing over sheaves on The lever 1045 is pivoted back on the lower carriage, and on the letter-spacing carriage is a stud 105,which engages the lever and carries it along in its transverse movement. I Then when the carriage travels back, the spring-drum 102 0perates to draw the said lever back by means of cord 103, and thus the inking-carriage is rotated and the ink is perfectly distributed. The type in their back action, after having made an impression, strike the inking-cushion and are inked for further work.

Beneath the inking carriage and supported on a frame therefor each type-arm is provided with a spring 106, Fig. 5, against which the arm rests to keep the type out of normal contact with the inking-cushion, but of sufficient flexibility to permit contact on the back throw after impressions. i

A pawl-and-ratchet connection is made be-'- tween the pinion 101 and drum 102, so that when the spring in the drum recovers itself and winds up the cord thereon it does not rotate the pinion 101. The inking-cushi0n is thus made to travel round one way.

On the shaft 45 of the escapement mechanism is secured a sleeve 105. The ratchetwheel 44 is fixed on this sleeve, which has a slot 106, a locking-pin, and a spring 107, by and through which the ratchet-wheel 14 is held normally in engagement with its rack. When for any reason it is desired to move the carriages without turning this wheel, the lever 108 serves this purpose. The arm 109 engages a shoulder on said sleeve, so that when the lever is moved to the left, Fig. 3, the ratchet-wheel can be thrown out of gear, and when it is released the said wheel will be forced back into gear.

A ratchet 109 on the wheel 44: enables said Wheel to turn one way without turning the shaft 45 and the connected escapement mechanism.
