PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 774,658, dated November 8, 1904. Application filed February 12, 1904. Serial No. 193,246. (No model.)

T0 rtZZ- whom it 77MT/LI/ concern:

Be it known that I,JosEPH S. DUNCAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

This invention relates to printing-machines; and its object is to enable a close imitation of type-written letters in printing circular-letters by printing an autograph signature on the circular-letter in the one printing operation and in a different-colored ink from the text of the letter.

The invention also'has for its object to provide means which can be readily attached to the platen of a printing-machine for automatically printing a signature or other supplemental matter on a circular-letter, and it has other objects in view, which will appear hereinafter.

In the accompanying drawings I have illustrated one manner of embodying the invention in physical form.

Referring to the drawings, Figure 1 shows the invention applied to the platen of a printing-machine, which is illustrated partly in section. illustrating several positions of the shifter. Figs. 6 and 7 show the invention in normal position at rest and in printing position, respectively. Fig. 8 is a detail sectional View of the inking-pad-shifting means. Fig. 9 is adetail view showing particularly the stampshifter and the spring for returning the stamp to normal position. Fig. 10 is a bottom plan view. Fig. 11 is a top plan view of a portion of the bracket.

I believe that my invention can be applied to a variety of platen printing-machines, and itwill be understood, therefore, that I do not limit or restrict the invention to embodiment with a machine of any particular kind. For this reason I have not deemed it necessary to illustrate or describe in detail the construction of a printing-machine, as it appears am ply suflicient to properly understand the invention to say that the signatureprinting mechanism is attached to a platen 15, which Figs. 2 to 5, inclusive, are detail views' carries a sheet in the usual manner into printing contact with a form on the bed 16. The platen is mounted on a shaft or studs 17 in the main frame 18 and may be actuated by any suitable means, such as the segment-gears 19 19' on each side of the machine, the segments 19 being carried by arms 20, which are rocked by means of suitable connections with the power-shaft 21 and are connected also with arms 22 on each side of the machine carrying rolls 23 for inking the form of the printing-machine.

The signature-printing device is supported in normal position alongside the platen, Fig. 6, by a bracket 24:, which is adjustably secured by bolts 25 to the under side of the platen, Fig. 10. The signature-form, which I will refer to for convenience as the stamp, 26, is carried by one end of an arm 27, which is pivotally connected by links 28 and 29 to the bracket 24. This arm, which I will call the stamp-arinfis adapted to be shifted to carry the stamp in the arc of a circle described from the pivot-pin 30 of the link 28 between position at rest alongside of the platen,'Fig. 6, and printing position on the platen, Fig. 7 This movement of the stamparm is accomplished bymeans of a shifter 31, which is also mounted on the pivot-pin 30 and is normally held in contact with an arm 32 on the link 28 by a spring 33. An adjustable stop 34, Figs. 2 to 5, may be provided on the shifter to engage the arm 32, so that the shifting movement of the stamp may be properly adjusted and regulated. The shifter is operated by a tripper, which comprises an adj ustable arm 35, fastened rigidly on the platen shaft or stud or other part and carrying an antifriction-roller 35, Fig. 1. In Figs. 2 to 5 I have illustrated several positions of the shifter to indicate its operation, and referring thereto, Fig. 2 shows the'shifter in the position it occupies when the platen is at rest, as shown in Fig. 1. The tripper is so located and adjusted with reference to the shifter that as the platen moves forward (as indicated by arrows in Figs. 2 and 3) to printing position one side, 36, of the shifter travels against one side of the tripper, and in passing the tripper the shifter is swung slightly thereby against the tension of spring 33 into the position shown in Fig. 3; but this movement of the shifter is not communicated to any of the other parts and performs no function. On the return movement of the platen, as indicated by arrows in Figs. 4 and 5, the other side, 37, of the shifter engages the tripper, Fig. 4, and as the return movement of the platen continues the shifter travels on the tripper and is finally swung on its pivot to the position shown in Fig. 5 against the tension of the spring 38, Figs. 9, 10, which is attached to link 28 and the bracket 24: and is adapted to return the shifter to its normal position, Fig. 2, as soon as it passes the tripper on the return movement of the platen. It will thus be understood that on the forward movement of the platen the shifter is moved in passing the tripper from the position shown in Fig. 2 to the position shown in Fig. 3 and is returned to the position shown in Fig. 2 after passing the tripper by the spring 33, and it will also be understood that upon the return movement of the platen the shifter travels from its outer end for a distance up toward its pivot and then back again to its outer end on the tripper, as indicated in Figs. 4 and 5, and during this movement the shifter engages the arm 32 and causes the link 28 to swing on its pivot 30 and swing the stamp from position at rest into printing position. This movement of the stamp is made quickly while the platen is returning from printing position, and the operation of feeding sheets to the printing-machine will not in any way be interfered with by the automatically and quickly operating signature-stamp. When the spring 38 pulls the stamp back from printing position to normal position, a pin 39 on the link 28 engages and rides against a springarm 40, which may be conveniently supported by the tripper-arm 35. This arm 40 acts as a guide-stop to prevent the printing devices from returning to normal position with a jerk and to allow the stamp and stamp-arm to swing backward easily into normal position. The spring-arm is bent or inclined; Fig. 7, rearwardly from the point where the pin first engages it as the link and other printing-devices swing back to position at rest.

The stamp 26, which may consist of any suitable form, is carried by a holder 41, which is fastened in place on the stamp-arm by screws 42 and is adjusted by the screws 43, which pass through the arm and bear upon the holder.

The inking device comprises a pad 44, which is supported in place on the bracket 2 L beneath the stamp when the latter is in position at rest, and this pad is adjusted in proper position by the adjusting-screws 45, which operate in the bracket. The inking-pad is held in place on the bracket by a spring 46,

which is attached to the pad and passesthrough an opening 47 in the top 48 of the bracket and is fastened thereto below the top. It is desirable that the stamp should not engage the pad at the same place each time, and for this reason I provide means for shifting the pad so that the stamp will make contact with a different part of the face of the pad at each operation of the machine. The pad-shifting means comprises a shaft 49, which is journaled in a bearing 50 on the bracket and carries a disk 51, provided with a crank-pin 52, which worksin an opening 53 in the under side of the pad, Fig. 8. This crank-shaft is operated to shift the pad by means of a lever 54, which carries afeed-pawl 55,engaging the ratchet 56,mounted on the shaft49. The lever 54: projects into the path of movement of the stamp-arm, as shown in Fig. 10, and is engaged and operated by the stamp-arm when it moves to carry the stamp into printingposition. Whenever the shaft 49 is turned, the inking-pad is shifted on the bracket, and this shifting movement of the pad occurs at each operation of the stamp-arm, so that when the stamp returns to its normal position the pad will be at rest and remain so until the stamp-arm has carried the stamp a given distance to printing position. A springarm 57 is arranged to operate at the same time upon the feed-pawl and the lever for returning the lever to normal position, Fig. 10; but any other suitable means for this purpose may be employed. 1 may also employ a locking-dog 58 to engage and hold the ratchet against reverse movement. It is desirable that the stamp should not lie in actual contact with the pad while the machine is not in operation to avoid unnecessary wear upon the pad and prevent it from becoming misshapen by a constantly-applied pressure. For this reason I provide means to prevent the stamp from contacting with the pad until immediately before the operation of the stamp begins. and this means comprises a yielding stop 59, which is adapted to support the stamp-arm upon its return to normal position and hold the stamp slightly elevated above the pad, Fig. 6. The stamp-arm is held with the pad in this elevated position until the platen has been carried to printing position, at which time the top of the stamp-arm engages a bracket 60 or some other fixed part on the. main frame of the machine with suificient force to over come the pressure of the yielding stop, so that the stamp will be carried against the pad. I also provide a flat spring-arm 61 on the bracket, Figs. 6,7, to engage the stamp-arm when the stamp reaches printing position and prevent it from rebounding.

The operation of the signature-printing device will be readily understood from the foregoing description of the construction. The arrangement of the parts is such that the stamp is caused to operate upon the sheet carried by the platen after the sheet has been printed and on the return movement of the platen to normal position. The stamp is not only carried forward to print upon the sheet, but is carried back to its normal position at rest during this return movement of the platen, and the operation-of the stamp is performed quickly, so that it will not interfere in any way with the operation of removing the printed sheet and placing a fresh sheet in position on the platen.

The signature-printing device can be adjusted on the platen and the tripper can be adjusted relative thereto to provide for printing the signature at any desired place on the sheet, and it will be understood that instead of printing a signature the device may be employed for printing any other desired matter, as the stamp can be changed and the parts adjusted as desired.

The device is simple in construction and automatic in operation, and it can be applied to a variety of platen printing-machines.

Of course the stamp may print in a differentcolored ink from that employed in printing the text of the letter, and as the stamp can print an autograph signature it will be seen that a complete letter can be printed in very close imitation of a type-written and personally-signed letter.

The platen which carries the sheet to the first printing operation, being the customary printing operation of platen printingmachines, can be oscillated by other means than that disclosed in the drawings; but my invention does not pertain to the platen nor to the means for operating it, but to a printing device carried by the platen, preferably at one side thereof and adapted to be moved in an angular direction with relation to the movement of the platen to print upon the sheet while carried by the platen within the limits of its oscillating movement.
