PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 774,912, dated November 15, 1904.

Application filed March 28, 1904.

T (ZZZ whom it may concern: I

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.

The primary object of this invention is to print circular letters and an individual address on each letter in one printing operation in the same machine.

Another object of the invention is to print in the one operation the salutation Dear Sir: or Dear Sirs:, as each address may require.

The invention also has for its object to provide a machine of simple construction for printing and addressing circular letters, which can be easily operated and which works to all intents and purposes like an ordinary jobprinting press; and it has other objects in View, which will be fully pointed out hereinafter-in the detail description of the machine, which isillustrated in the accompanying drawings as showing one embodiment of the invention.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 is a sectional view on the line 2 2 of Fig. 1 without the base. Fig. 3 is a detail sectional view on the line 3 3 of Fig. 2. Fig. 4 is a rear elevation of'the ma-- chine. Fig. 5 is a vertical sectional View on the line 5 5 of Fig. 4. Figs. 6 and 7 are detail views showing the operating devices for the drum which carries the chain of address-forms. Figs. 8, 9, and 10 are sectional views showing in detail the devices for printing the salutation. Figs. 11, 12, and 13 are similar views showing another construction of the device for printing the Salutation.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

Referring to the drawings, 15 is a main frame mounted upon a base 16 and carrying the operative parts of the machine. A power-shaft 17 is journaled in bearings in the frame and carries a belt-pulley 18 and a pinion 19, the latter meshing with a gear 20 on the countershaft 21 and carrying the cam 26.

Serial No. 200,391. (No model.)

shaft 21. The frame is provided with a bed 22 and an ink-plate 23, the latter being mounted on a bracket 23 on the main frame. A weighted pawl 24 is carried by a crank-lever 25, which is operated bya cam 26 to cause the pawl to engage ratchet-teeth 27 on the under side of the ink-plate to revolve the ink-plate in a well-known manner.

The ink-rollers 29 are carried by rods 30 in a rocking frame 31, mounted on the counter- These rods work in bearings 32 in said rocking frame, and a spring 33 is fastened at one end 34, Fig. 1, on each rod between the hearings to cause the rollers to properly engage the type-form.

The usual trucks 35 are provided at each end of the ink rollers to travel on the tracks 36 at each side of the bed, Fig. 2.

The platen 37 is adjustably mounted on a platen-frame 38, which oscillates on a shaft 39, and its oscillation is effected through the medium of links 40 on the sides of the machine, which are pivotal] y connected to cranks 41 on the counter-shaft and to the concentrically-turned ends of an eccentric shaft 42 on the platen-frame. A link 43 is pivotallyconnected at one end to the main frame at 44 and at itsother end to the concentric portion of the shaft 42, and a throw-off handle 45 is also fastened to said shaft to adjust the same and prevent the platen from movinginto printingcontact with the form. V

I do not confine myself to the use of a form of any particular character or to any especial means for mounting the form on the bed; but for illustrative purposes I have shown a form 46 made up, preferably, of rubber type arranged in trays 47, Fig. 3, which are secured on a holder or chase 48 by adjustable side strips 49. This holder is fastened to the bed by any suitable means.

I may employ address-forms made up of rubber or other type or printingplates or other equivalent devices adapted to be connected into a chain or belt to travel over a drum or similar device to bring the addresses successively into printing position adjacent to the main frame, and in the drawings 1 have shown a chain 50 made up of addressforms linked together in any suitable manner and arranged to travel on a rectangular drum 51, provided on each side with a recess 64 and mounted or formed on the end of a drumshaft 52, which is carried by an oscillating drum-frame 53. mounted on the shaft 39. A rod 54 is connected at one end to the drumshaft, and its other end is provided with a fork 55 to receive the counter-shaft. Aspring 56 is fastened at one end to a collar 57 on the counter-shaft and at its other end to the rod 54: at 58, the purpose of this spring being to hold the antifriction-roller 59, mounted on the rod, against the operatingcan160 on the counter-shaftand to pull the drum back from printing position after the printing operation has been completed. In the swinging movement of the drum caused by this spring and cam the drum is revolved a one-quarter turn to bring a new address into printing position, and this feeding movement of the drum is accomplished by two arms in the nature of

pawls

61 and 62, pivoted at 63 on a bracket 63 on the main frame. On the rearward movement of the drum from the position shown in broken lines to the position shown in full lines in Fig. 6 a projection 61 of suitable character on the pawl 61 engages the recess 64 on that side of the drum which has been the back during the preceding printing operation, and on the continued rearward movement of the drum against the fixed pawl the drum is revolved a portion of a quarter-turn. Thereafter on the forward movement of the drum a projection 62 on the pawl 62 engages the recess 64: on the uppermost side of the drum, and on the continued forward movement of the drum this pawl causes the drum to complete its quarter-turn, as shown in Fig. 7. Instead of the recesses 6 the drum may be provided with some equivalent device with which the pawls can engage to revolve the drum, as heretofore described. The rear ends of the pawls behind the pivot 63 are connected by a spring 65 to hold the pawls in proper position for their work, and a lug 65 on one pawl projects across the other to prevent the spring from from pulling them out of operative position. I prefer also to provide a safety projection 62 on the pawl 62 to engage the drum in event the projection 62 fails to do so, and thus insure the completion of the quarter-turn of the drum.

The frame 53 is provided with an arm 66, which projects beneath the drum to form a back for the address-form immediately below the one which is backed by the drum in position to print, and this arm is arranged to hold the address-form in position to be engaged and inked by the inking-rollers, and thus each of the address-forms will be inked twice, once while in front of the arm and once while in printing position on the drum.

Referring to Figs. 9, 10, and 11, the salu'-' tation-form 67 is carried by a plate 68, which is adjustably mounted on the bed to bring said form in proper position between the address and body forms. For printing the singular salutation Dear Sir: or the plural salutation Dear Sirs:, as each address requires, l have provided a movable letter s, which is automatically moved in and out of printing position. As the plural salutation is employed more frequently than the singular, 1 preferably construct the machine with the final letter s always in printing position and provide for moving it out of of printing position when the singular salutation is required. This final letter s is carried on an arm 69, which projects through a slot in the plate 68 to bring said letter into proper alincment and position. The arm is carried by a lever 71, which is fastened to a shaft 72, journaled in bearings on the back of the bed and carrying a short arm 73. A crank-lever 74: is pivoted at to the bed and has a short arm 76 arranged to engage the arm 73 and its long arm 77 bent in position to be engaged by a projection 78 on each address-form which requires a singular salutation. On the forward movement of the drum, carrying into printing position an address-form requiring a singular salutation, the projection 78 on each address-form will engage and move the crank-lever 74:, which acts as a trigger and operates lever 71 and causes the arm 69, carrying the final letter s, to be sufficiently retracted to prevent said letter from printing. The forward movement of the arm 69 can be regulated by a screw 79 to properly adjust the letter s, and a spring presses the arm forward, with the letter s. carried thereby, held normally in printing position.

In Figs. 11 to 13 I have shown a construction which permits the movable letter s to be held normally in or out of operative position. In this construction the letter s is carried by an arm 69, which projects through a slot 70 in the plate 68, which carries the salutation-form 67, and the arm is carried by a lever 71, which is fastened on a rock-shaft 72'. A two-arm lever 73 is also fastened on this shaft 72, and the trigger 74E is pivoted at 75 and extends above the shaft 72. The trigger is provided with a shoulder 76 below the plane of the shaft 72 and with a shoulder 76 above the plane of said shaft, and a spring 80 is fastened at 80 to the frame and is adapted to be connected to either end of the lever 73 by a pin 95, which enters the openings and 95. When the pin is arranged in the opening 95 in the lower arm of the lever 73, the spring will pull the pin against the shoulder 76 of the trigger and hold the movable letter s normally in printing position, Fig. 11, and when the pin is arranged in the opening 95 in the upper arm of the lever the spring will pull the pin against the shoulder '76 on the trigger and cause the lever 71 to hold the movable letter s normally out of printing position. By constructing the machine in this way it can be used in connection with singular or plural addresses only or some of each, and it can be quickly adjusted, as occasion may require, for operation in connection with address-lists which predominate in singular or plural addresses. In this construction, as in that shownin Figs. 8 to 10, the lower end 77 of the trigger is engaged by a projection 78 on the addressform to operate the trigger and the devices connected therewith. In Fig. 11 the letter s is held normally in printing position,

and the projections would be located on singular address-forms for the purpose of operating the trigger to move the letter s out of printing position. ter s is held normally out of printing position,and the projections would be located on the plural address-forms to move the letter s into printing position. A paper-holder 81 is pivoted at 82 on the platen, and an arm 88 on each side thereof carries an antifriction-roller 8&, which travels on a curved track on the main frame and is held in operative position by the spring 86. This paper-holder carries a flat plate 87, which covers the address-form in front of the arm 66 during the printing operation to prevent it from making an impression on the sheet. Y

A date-form 88, Fig. 2, is carried by a plate 89, adjustably mounted on the bed, and this form and the singular salutation-form may be made up of type set in a tray like the bodyform a6, or these forms can be molded on a strip of rubber and pasted or otherwise affixed to the

plates

89 and 68, respectively.

The machine is of comparatively simple construction and operates automatically in general respects substantially similar to an ordinary job-printing press, printing the body of the letter, the date, a separate address, and the proper salutation therefor on a sheet at each operation of the machine. The body of the letter may also contain the writers name in type, or an imitation signature may be provided, or this may be omitted and the signature written after the letter is printed. By thus inking the address-forms at the same time that the body-form is inked and printing both the address and the body in one operation I produce a printed letter which may be made to very closely imitate a type-written letter if type and ink of the proper kind are employed, and the character of the impression throughout the address and body of the letter will be uniform. Various means may be employed for adjusting the parts of the machine to secure the proper impression, and for this purpose the roller 59 may be eccentrically mounted in some well known manner which it is vunnecessary to describe in detail, as it forms no part of the present invention. It

In Figs. 12 and 13 the letwill be understood, of course, that the sheets are placed one at a time in proper position on the platen and carried thereby into printing position and that after each printing operation a new address-form is automatically brought up into printing position and the salutation-form changed whenever req uired by the character of the address.

While I have referred to the chain as made up of address-forms, it will be apparent that these forms may be made to print any other desirable subject-matter than the address without departing from the invention, and by referring to these forms as address-forms in the specification and claims it will be understood that I do not restrict the invention specifically to forms which print an address.
