TYPE-WRITING ATTACHMENT FQR USE ON PLATEN PRINTING-PRESSES.

Specification of Letters Patent.

Patented Get. ill), 1999.

Application filed March 10, 1909. Serial No. 482,602.

To all whom it may concern.-

Be it known that we, CHELSEA C. FRASER and GUY V. LILLEY, citizens of the United States, residing at Saginaw, inthe county of Saginaw and State of Michigan, have invented a new and useful Type-VVriting Attachment for Use on Platen Printing-Presses, of which the following is a specification.

Our invention embraces the creation of an appliance whereby printing-presses of the kind mentioned above are, with their regular and special accessories and equipment, utilized for the production of imitation-type written letters in multiple quantities.

The objects of the machine are': First, to provide a means for inking the types which shall have for its purpose the production, as soon as printed, of non-offsetting impressions, immediately and thoroughly dry for all practical purposes, thus enabling instant delivery of an order and its instant use by the client, saving the several hours delay for drying made arbitrary by present methods of inking in this line of work. Second, to provide the printing-press (nearly all professional printers are supplied with suitable types) with a pre-inked ribbon intermittently moving, between impressions, across the face of the type-form, after the princi-ple of a ribbon on a commercial typewriter, thus to secure a fresh inking-surface at each impression. Third, to provide a means whereby said ribbon may reciprocate, when at its ends and continue to wind in the reverse direction, alternately filling one spool and emptying the other, by the continued and natural action of the printing-press. Fourth, to provide in the ribbon a uniform oscillating-reciprocating motion, intermittently between strikes or impressions of the types, whereby the type-lines, when typeform is long and necessarily placed horizontally in the chase, may find at each new impression a change of ribbon inking surface throughout their entire length, the same as when the type-form is locked up vertically. In an attachment of this character the movements of rotation and oscillation, by occurring alternately, give a much better mechanical action than if they took place at the same time, the latter method causing a pull on the ribbon from two different directions at the one time, obviously causing a friction absent in our arrangement. Fifth, to provide, for the double purpose of economy of ribbon and of uniformity of inking, means by which the afore-mentioned intermittent oscillating-reciprocating movement of the ribbon may be controlled and adjusted to certain adequate degrees or extents at the will of the operator, according to his needs, as emphasized by the width of the type-form in correlation with the width of ribbon used. Sixth, by reason of the fact that printers clients ordering this kind of work generally Wish it to match in color the ribbon or ribbons of their own commercial typewriter or typewriters, so that headings, etc. may be properly and as indistinguishably as possible added to the printed body after such printing is done,to provide a convenient disintegral spool whose two flanges, disunited from the spindle, may be quickly connected to a corresponding spindle cored in the new ribbon desired, thus saving much unwinding of the old ribbon and winding of the new each time a change is desired. Seventh, to supply brackets of such construction that when attachment is once connected to the printing-press, and adjusted, the parts in the way for other kinds of printing may be con veniently removed, and replaced again with equal despatch without disturbing the former adjustment. Likewise to provide, by a two-piece bracket, a means for withdrawing and replacing the spools without disturbing their former alinement adjustments. Likewise to provide, by bolt and screw, means whereby, in the matter of communicating connections for transmitting motion between printing-press and attachment, such connections may be readily and effectively separated, and again reconnected, without disturbing their former adjustments. o attain these objects by the mechanism illustrated in the accompanying drawings, in

I which- Figure 1 is a front elevation of the entire upper section of the attachment; Fig. 1 is an elevation of one of the ratchet wheels contributing to rotate the two spools; Fig. 2, an end elevation, partly in section, as seen from the left in Fig. 1; Fig. 3 a plan view of the above, with addition of the missing portion of In; Fig. 4, a back elevation of the mech anism-producing oscillating movement; Fig. 5, a front elevation of the entire lower section of the attachment, excepting 13;) and its connections; Fig. 6, an end elevation of the lower spool movement, showing (in section) how the bracket may clamp to the press frame; Fig. 6 a perspective View of the transmission-wire of the lower spool movement; Fig. 6 a back elevation of the press leg (in part) and of the clamp (in full) to which the aforesaid transmission-wire connects; Fig. 7 a plan view of the mechanism bracket, lower section; Fig. 8, a similar view of the opposite bracket F, G; Fig. 9, an end elevation of the last-named; Fig. 10, a plan and projection of one of the spool flanges and its connecting spindle; Fig. 11, a section of the spool spindle, front elevation; Fig. 12, an end view of the preceding; Fig. 13, a perspective of the complete attachment in operation, on a Gordon printing-press.

Similar letters refer to similar parts throughout the various views.

U ppm sectz'0n.Practically all platen printing-presses have connecting rods which communicate movement of an intermittent character between the platen, and the chasebed, or form-rollers. It is one of these connecting rods that we utilize for securing movement for the upper section of our attachment.

A, AA, B and C constitute the framework, or brackets. B attaches to A by screws a and a, Figs. 1 and 4. At point Se is a slotwhich receives press screw PS, Fig. 13, by means of which the entire bracket, as assembled, may be shoved backward or for ward sufficiently to bring its spool in alinement With the spool of the lower section.

Sb is a screw holding A and AA together. Its withdrawal admits the removal and replacement of A, quickly, in conjunction with a like treatment of C (which works similarly), without readjustment or realinement of the spools. The removal of C alone permits the unseating of that end of the spool shaft, and the withdrawal and replacement of the spool, when desired. Brackets A and C could differ from these shapes, in order to fit other kinds of platen printing-presses, but the two-piece principle named should be maintained.

A strap-clamp, b, engages press rod PR, Fig. 13, by bolt 0, Fig. 1. To 6 is pivoted by loop and shoulder-bolt d, transmission wire 6. To 0 are attached two stop-collars, f, 7, which are adjusted on e by set-screws g, g. These stop-collars are for the purpose of diminishing the movement of PR, as communicated to h, the main lever, by e passing freely through a hole in i, a swivel-head riveted loosely to the extremity of it. h pivots to A by a short stud, j, which is frictioned half-way into A, and h is retained from wabble by confiner it, connected by screw to the outer face of A. This end of 72, is inset, after passing A, as shown in Fig. 3. At the extreme end of this inset is pivoted, by shoulder-screw Z, a pawl, m, Fig. which engages with rotary ratchet wheel a. n is fastened on spool-shaft 0, Fig. 1, by a set-screw s, Fig. 1, that does not rise above the surface of ns hub (next to A), thus giving a uniform friction bearing for bandspring 2), which fastens above, by screw, to a projecting lug, g, of A. In this manner a uniform friction is obtained on 0 which will restrain a from back-slipping when m rises to set, and which, furthermore, will keep the spool from turning from mere weight of active ribbon, when m is put out of commission and 0 is in reverse. Shaft 0 is grooved or key-wayed approximately its full length, to receive tongue, or key, Ba, Fig. 10, one of which is connected to each spool flange, BZ), Fig. 10. The flanges support a circular threaded lug, Bo, which engages with spool spindle Bel by threaded end Be, Fig. 11. The ribbon is locked by a wire, Bf, Fig. 12, which is sewed to the ribbon across each of its two ends, the wire catching on the underside of the spindle slot B Fig. 11, across its ends, and runs into slot B Fig. 11. The bearing of 0 is had in holes half-way through A and C, Fig. 1, the hole in A really running clear through originally, but.- half its length having been filled by 7', against which 0 butts.

At points r, Fig. 2, is a rectangular opening through It. Through this opening projects the end of a lever, s, the space seating it being wide enough to take up all side play of 8. See Fig. 3. s pivots to washer-screw t by shoulder-screw a. This lever sustains, by shoulder-screw z: acting as a pivot, oscillator pawl 10, Fig. 1, which drives oscillator ratchet 00, same figure. Coil-spring r, engaging its ends with the shank of '11, and body of 8, through small holes, and wound about the offset hub of w, prevents w from slipping. m revolves in B upon its own hub, and is retained in position by washer-screw t, Fig. 1. It has six tapped holes-of which .2, Fig. 4;, is onein its back surface, beginning at the center and running straight outward at uniform distances from one another. These holes supply the means of gaging the extent of the oscillating movement to corresponding fixed degreos through the medium of: the connecting rod, (m, pivoting to 2 by shouldenscrew ((1), Fig. 3, and pivoting its other end to jacket-head ac by means of a similar screw, ad; ac riding upon two guide-rods, ah and (tie, which rest half-way in A at the one end and are held by setscrews ad, (42', Fig. l, in B, at the other end; a perpendicular support, (re (a part of ac), to which is attached, by screws af, af, spool conveyer a: Fig. 3, which straddles the adjacent spool flange. (A band-spring, (1.2, with elbow-j aw, connecting to B by a, Fig. 41-, keeps a? from back-slipping while 1.0 rises for set.) It will be seen, by this arrangement, that at each forward movement of the press platen toward the type-form, PR will communicate motion to lift 7L, thereby drawing down 11?, and rotating the spool, and at the same time raising and setting w, and that, as the platen recedes from the type-form, 71 will be lowered, thereby drawing down to and driving the spool in oscillation, while on sets itself. Lower section.lnasmuch as practically all platen printing-presses are constructed With a movable chase-bed acting in conjunction with a stationary platen-bed, or vice versa, it will be observed that a means is thus established for securing an intermittent movement to an attachment which may be fastened to either the bed or platen framework of the press in connection with the other part. Our treatment makes use, in this instance, of a Gordon press, which has a movable chase-bed and a stationary platenframework, but movable platen. D, E, F and G are the brackets of this portion of our attachment. They maybe constructed of different outlines to accommodate themselves to connection with other makes of platen printing-presses; but the two-piecefeature of the left bracket (embraced in F and G, Fig. 5) in which screw Bh engages slot Bz' is to be maintained in all forms of this bracket, to admit of the convenient release of the spool, and its replacement, without danger of disturbing the former alinement adjustment. An uprising flange, Bk, on each side of F, makes a channel in F in which G slides and by which it is retained in alinement with D, without disturbing clamp set-screws Cc, connecting attachment to the press framework. The action of this lower section, and the construction of its parts, with the exceptions following, are identical with the upper section.

The main lever, BZ, Fig. 6, is of a T pattern, and pivots by shoulder-screw Bm to the inner face of the forward upright of D, at a point just below spool shaft B0. Pivoted by loop to the lower extremity of B1, by shoulder-screw Ba, is transmission-wire By). This is in two sections, each engaging the other by loop, as illustrated in Fig. 6 One of the pieces carries two set-screwed stopcollars, B9, one of which rests within the space between the loops and the other beyond them. This method of diminishing the motion of the press, at this end, permits of flush connections at each end of the transmission-wire, made desirable by the lack of space and character of the connections. The opposite end of Bp pivots by loop with a loose collar, Br, which encircles the clamp screw, Bs. The clamp, Bx, may be afiixed permanently to the press-leg, as shown in Fig. 6 An elbow-jawed band-spring, Bu, 5, performs the same office as as, Fig. 4,

but is seated on D by screw B0. The movement of this section of the apparatus is in exact accord with its upper mate; the respective spools oscillate in the same plane, and at the same time; and they also rotate in sympathy by the pawl of the one rotary ratchet wheel being thrown back out of action,

while its contemporary remains active and unwinds the ribbon on the other spool as itwindsit up upon its own spool. The ribbon remains across the face of the type at all positions of the press platen; thus it-is,

from the form-rollers of the press, and at-' tached rigidly to either the type-form, the chase, or the grippers. We, therefore, do not claim a right to Letters Patent in the use of a ribbon or fabric, for the purpose specified, depositing ink upon the matter to be printed through the medium of a roller supply, but
