Application filed November 17, 1913. Serial No. 801,325.

To all whom it may concern:

Be it known that I, Josnrrr 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.

My present invention relates in general to printing machines and has more particular reference to machines adapted for printing form letters in simulation of typewritten letters and for providing each letter with an address and Salutation arranged in proper relation to the body of the letter.

Qne of the primary objects of this invention is the provision of a machine of this general character which shall embody simple and eflicient mechanism for transferring an address form, bearing an address and a Salutation, from a magazine to the bed at each reciprocation thereof, for positioning and holding such transferred address form on the bed in proper relation to the letter form which prints the body of the letter and for removing the address form from the bed at the opposite end of the bed stroke and transferring the removed form to a suitable receptacle such as a tray wherein the address forms are stacked after they have passed in succession through the machine.

Another object is to provide a form bed of novel construction adapted to rigidly sup port the address form during the printing operation and to facilitate the positioning of an address form on the bed and the removal of the form therefrom.

Still another object is the provision of a machine in which the inking ribbon, through which the impressions are taken, will be carried by the reciprocatory bed and fed across the bed at each reciprocation thereof by feeding mechanism which is stationarily mounted so that it is not required to travel with the bed.

Another object is the provision of novel mountings for the impression cylinder, by means of which said cylinder maybe thrown into inoperative position whenever it may be desireable to skip one or more impressions.

The manner in which these and other objects of the present invention are accomplished will be made clear by the following description andfaccompanying drawings of one form of meansfor, carrying the nven- Fig. 2 is a side elevation thereof, looking.

at the near-side of the machine disclosed in Fig. 1; 4

Fig. 6 is a similar View on the line 6-6 of Fig. 1, and

Fig. 7 is an enlarged fragmentary view showing some of the parts illustrated in Fig. 6 in another position.

On the drawings reference character 8 designates generally the main frame of the machine, which is suitably shaped and pro portioned to carry the mechanisms which adapt the machine to the performance of its various functions. The bed 9, which is adapted to carry the letter form and an ad dress form, is mounted to reciprocate longi' tudinally of the machine upon suitable guide rollers 11 carried by rigid arms of various I The address forms 14 (Fig. 1) are prefer-' ably formed of sheet metal, having the address and the salutation corresponding thereto struck up from the body of the metal. The forms may be provided with one or more index tabs 15 if desired, secured thereto in the usual manner. Since the detailed construction of the letter form and address form are not essentially involved in the present invention I have illustrated these forms diagramatically only, such illustration being considered sufiicient for l i; i)

an understanding of my present invention. The address forms are contained in a magazine 16 disposed at one side of the path of travel of the reciproeatory bed and at each reciprocation of the bed the lowermost form in the magazine is transferred from the magazine to printing position on the bed adjacent to the letter form.

The mechanism for transferring the ad dress forms'from the magazine to the bed comprises a pair of guides 17 disposed beneath the magazine and extending inwardly approximately to the adjacent edge of the bed. A forked slide 18 is adapted to travel back and forth on said guides to push the lowermost address form from the magazine along the guides to the bed, the rear end of the slide being adapted to support the remaining forms in the magazine during the transferring operation. The forks of the slide are connected together by a framework 19, which by means of a forked link 21 is pivotally connected with an operating lever 22 mounted to oscillate on a shaft 23 fixed near the bottom of the main frame of the machine. A second lever 24, also pivoted on shaft 23, carries at its upper end a follower 25 which is engaged in a cam groove 26 formed on the periphery of a drum 27 fixedly mounted on the transversely extending shaft 28. Levers 22 and 24 are rigidly connected together by means of a web 29 so that when the lever 24 is oscillated upon rotation of the drum 27 the lever 2:2 is actuated to reciprocate the slide 18 and transfer an address form from the magazine onto the bed.

The mechanism for reciprocating the bed, which will be later described, is so timed with respect to the operation of the transferring slide that an address form is moved onto the bed as the bed approaches the limit of its travel to the left, viewing Figs. 1 and 2, upon its return stroke. The movement of the slide 18 is such that the address form is brought into contiguous relation with the head end of the letter form and the address form is held in proper position with respect to the letter form during the printing operation by means of a member or holding device 31 (Figs. 1, 6 and 7) pivoted at its rear end to the bed on a pivot pin 32 and extending forwardly approximately in the plane of the upper surface of the bed. The front end of the holding device is slightly inclined upwardly as indicated at 33 and is provided with a groove 34 adapted to receive the rear end of the address form, whereby said form is held in position. It will be observed that the device 31 is prevented from excessive movement by a pin 35 projecting from the device into an enlarged opening 36 formed in the frame of the bed.

As thebed approaches the end of its move-- ment upon its return stroke an address form is moved by the transferring slides into juxtaposition to the letter form and over the holding device 31. As the bed continues its rearward travel the holding device moves out from beneath the form so that the rear edge of the form drops down in front of the forward end of the device. Upon the forward or printing stroke of the bed the rear end of the form is engaged in the groove 34, so that the form is caused to travel with the bed and is held in proper relation to the letter form during the printing operation.

The impressions are taken from the letter and address forms simultaneously through an inking ribbon, by means of a rotatable paper carrying impression cylinder 37 having a high portion 38 (Fig. 5) adapted to cooperate with the printing forms upon the forward stroke of the bed. The bed is supported immediately beneath the impression cylinder by radial flanges or rollers 39 on the shaft 28, thus affording a rigid support directly beneath the impression cylinder. At one side the bed is provided with a downwardly disposed rack-bar 41 beneath which on the shaft 28 is mounted a segmental gear 42 adapted to mesh with said rack and propel the bed forwardly at a uniform speed during the printing operation. It might be mentioned at this point that the shaft 28 is the main shaft of the machine, from which the other mechanisms are driven, said main shaft receiving its power from any suitable source.

After the bed has completed its printing stroke it is desirable that it be returned at a relatively high speed, and for the purpose of effecting this return stroke and initiating the printing stroke at the requisite speed I have provided a bed-moving mechanism as follows:

A stub-shaft 43 mounted in the main frame of the machine is continuously driven by means of a gear wheel 44 mounted thereon, which meshes with an idler 45, driven from a gear 46 fixed on the shaft 28. The

gears

44 and 45 lie outside the planes upon which the sectional views shown in Figs. 5 and 6 are taken, but these gears are shown in dotted lines in these figures for the purpose of facilitating an understanding of the bed operating mechanism. Upon the inner end of shaft 43 is fixed a crank arm 47, provided at its outer end with a roller 48. A lever 49 pivoted on a transversely extending shaft 51 is provided on its outer face with a grooved track as indicated at 52 (Fig. 5) adapted to receive the roller 48. A pair of levers 53, also pivoted on shaft 51, are rigidly connected with the lever 49 by means of a web 54 so that the levers 53 are actuated directly from lever 49. The upper ends of levers 53 are connected by links 55 with the sides of the bed 9. The shaft 43 is continu- Ously rotated in a clockwise direction viewing Fig. 5, and in this figure the bed is shown at the extremity of its return stroke. As the shaft continues to rotate the arm 49 will be swung about its pivot toward the right by the crank arm 47 until the roller 48 travels out of the upper end of the track 52. Before this point is reached, however, the segmental gear 42 will have rotated sufficiently to mesh with the rack 41 so that the bed will be propelled from the segmental gear so long as the gear is in mesh therewith.v It will be observed that the upper end of the track 52 is cut off at an incline to permit the track 52 to leave the roller 48 when the segmental gear assumes control of the bed. In order that the gear 42 will properly mesh with the rack 41 I prefer to provide the gear with an inwardly extending pin 56, adapted upon rotation of the gear to engage with an abutment 57 on the bed. whereby the segmental gear and rack are brought into proper register. \Vhen the bed has been propelled to the end of its printing stroke by the segmental gear the parts will have assumed the position indicated in Fig. 6 and the upper end of track 52 will be positioned to receive the roller 48, which first moves the bed forwardly a short distance beyond the point at which it was left by the segmental gear and then returns the bed to the other extremity of its movement the return movement being effected with considerable rapidity because of the proximity of the roller 48 to the pivoted shaft 51 of the lever arm 49. It will be manifest from the foregoing that the initial printing stroke of the bed is instigated through the crank arm47, that during the printing operation the bed is propelled at a uniform speed from the segmental gear 42, and that the final completion of the forward movement of the'bed and the complete re turn movement of the bed are eflected by the crank arm.

The impression cylinder 37 is mounted to rotate on a shaft 58 and is continuously driven by means of a. gear wheel 59 fixed to one end of the cylinder and in turn actuated from the gear 46 through the idlers 61 and 62. The gear 61 is mounted concentrically with and rigidly connected to a stripperroller 63, which removes the paper from the impression cylinder in the usual manner,

and the paper is delivered from the stripper roll between rolls 64 and 65 against the lower face of a guide 66, from whence the paper is discharged onto a table or rack of any preferred construction (not shown). Rolls 64 and 65 are so situated with respect to the stripper roll that the paper will be directed between rolls 64 and 65 and will be gripped thereby.- Roll 64 is equipped with a gear 67 which is driven from the gear 61 through an idler 68, and the roll 65 is fric-- tionally driven from-the roll 64. The paper is presented to the impression cylinder from a table 69 and is gripped and held to the cylinder by grippers 71 operated by any suitable mechanism. The shaft 58, upon which the impression cylinder loosely turns, is provided at each end with an eccentric portion 72 supported in the main frame of the machine. For the purpose of elevating the cylinder out of operative relation with the bed whenever it may be desirable to skip an impression I have fixedly mounted on one of the eccentric projections 72 a lever 73 which is normally held in the position shown in Fig. 2 by means of a latch 74 pivoted on the main frame at 75 and urged into engagement with the shank of an operating handle 76 by means of an expansion spring 77. When the latch is manually released from the handle the lever 73 is rocked to turn the shaft in a clockwise direction, viewing Fig. 2, by means of a contraction spring 78 fixed at one end to the main frame of the machine and at its other end to the forward end of lever 73. Rotation of the shaft 58 about the eccentric projection 72 will lift the impression cylinder out operative position, the limit of movement of the lever 73 being determined by a pin 79 against which a shoulder on the lever 73 abuts. To throw the cylinder into operative relation again the handle 76 is depressed until the latch 74 is engaged therewith.

The impression is taken from the printing forms on the paper carried by the impression cylinder through an inking ribbon 81 extending transversely of the bed and carried by ribbon rolls 82 and 83 respectively mounted in suitable extensions on opposite sides of the bed. The ribbon is therefore carried back and forth by the bed in its reciprocatory movements and is at all times disposed over the letter and address forms. For the purpose of feeding the ribbon from one roll to the other I have provided mechanism which is mounted on the main frame of the machine and adapted to engage with the ratchet wheel 84 of the ribbon roll at the forward end of the bed which, as will be apparent from the drawings, is mounted beneath the plane of the ribbon when traversing the bed, while the other roll is mounted above the plane of the ribbon. On-the frame of the machine at the rear I have mounted an operating lever 85 on a stub shaft 86 concentrically with the ribbon roll 82, and this lever has pivoted thereon at 87 a dog 88 adapted to engagewith the ratchet wheel 84 and intermittently actuate the ribbon roll upon oscillation of the lever 85. A contraction spring 80 fixed at 90 to the main frame of the machine and at 89 to the lever 85 normally holds saidlever against abutment 91, as shown in Fig. 3. At the lower end of the lever 85 I have pivotally mounted at 92 a dog 93 which is normally held in the position shown in Fig. 3 by a contraction spring 94. A lever 95 pivoted on the main frame at 96 is provided with a pin or roller which engages with dog 93 when the lever is swung to the right, viewing Fig. 3, to thereby swing lever 85 to the right. This movement of the lever 95 is accomplished from a lever 97 pivoted on the shaft 23 and rigidly connected with the operating lever 22 by a web or casting 98, so that lever 97 is oscillated simultaneously with lever 22. A link 99 connects the upper end of lever 97 with the upper end of lever 95 so that lever 95 is oscillated at each oscillation of lever 97 The parts are so proportioned and timed that the arm 85 will be swung toward the right as the bed approaches the end of its return stroke, and for the purpose of withdrawing the dog 88 from the path of the ribbon roll ratchet 84 I have mounted an inclined pin or cam 101 in the path of the tail of the dog, whereby the dog is oscillated on its pivot to withdraw its operating finger or head from the path of the ratchet wheel. \Vhen the bed has reached the limit of its return stroke the ratchet wheel will be in alinement with and above the dog 88. At this time the pin or roller carried by the lever 95 travels 01f from the end of the pivotal finger 93, whereupon arm 85 is drawn toward the left, viewing Fig.3, by the spring 80 and as the tail of the dog 85 travels off from the pin 10.1 the dog engages with the ratchet wheel 84 and imparts a partial rotation to the ribbon roll to feed the ribbon across the bed at each reciprocation of the bed, and when the ribbon is entirely wound on roll 82 the rolls may be removed from their bearings and interchanged. Upon return movement of the lever 95 the finger 93 swings on its pivot against the force of spring 94, thereby ,permitting return movement of lever 95 without afiecting the arm 85.

The address forms which will be commonly used in connection with this machine, have an elevated portion upon which the printing characters are stamped up. It is of course essential that the address forms be supported during the printing operation immediately beneath the characters, and to afford a rigid support and at the same time facilitate the positioning of the address forms on the bed and their removal therefrom I have so constructed the bed that the address form supporting portion is movable up and down relatively to the body of the bed. I The address form supporting portion 102 of the bed is therefore pivotally mounted on the main portion of the bed at 103, and the drum which ise uipped with flanges or rollers 39 to support t e bed immediately beneath the impression cylinder is also provided with a flange or roller 104 which has an elevated portion 105, as best seen in Figs.

5 and 6. This elevated portion is so arranged that it will engage beneath the address form supporting portion 102 during the printing operation only and will travel from beneath the portion 102 before the bed reaches the extremity of its forward or printing stroke, thus permitting the portion 102 to drop downwardly onto the low portion of roller 104. The bed portion 102 remains in its depressed position upon the return stroke of the bed and during the positioning of a new address form thereon and is not elevated again into engagement with the address form until just prior to the passage of the address form beneath the impression cylinder. A rigid support for the address form immediately beneath the printing characters is thereby afforded during the printing operation and the support is depressed relatively to the remainder of the bed during the positioning of an address form thereon and the removal of the form therefrom.'

For the purpose of removing the address form from the bed at the end of the printing stroke I have provided mechanism which will now be described. At the end of the machine, in the path of the address form. carried by the bed, I have pivotally mounted upon the main frame of the machine between lugs 106 a plate or finger 107, the downwardly projecting end of which is yieldingly urged toward the oncoming address form by expansion'spring's 108. Upon the main frame of the machine I have provided an upwardly extending head 109 disposed in the path of the bed, the bed being provided with an elongated slot 111, as indicated in Fig. 1, to accommodate said head as the bed approaches the end of its printing stroke. This head carries at its upper end a ivotally mounted finger 112 which is norma 1y urged upwardlyinto the position shown 1n Fig? 6 and 7 by an expansion sprin 113. he end of the finger is also provi ed with a groove 114 similar to the groove 34 in the holding device 31. As the ed approaches the end of its printing stroke the address form travels over the finger 112 into engagement with the plate 107 which is also grooved to receive and engage with the forward end of the form. When the form has passed the head 109 the finger 112 is elevated by the spring 113 to engage with the rear end of the form. The address form is thereby held at each end between the plate 107 and the finger 112. The form support ing portion 102 of the bed is thereupon depressed and upon the return stroke ofithe bed this portion travels'out' from under the address form, leaving the form suspended between plate 107' and finger 112 at the for- "ward end of the machine.

For the purpose of transferring the removed address form to a tray or other suitform container 115 of any preferred construction, the container or tray being preferably supported in inclined position, as shown, by well known mechanism. A curved guide 116 is pivotally mounted at 117 and is normally disposed in the inoperative position shown in Fig. 4 with the receiving end 118 of the guide beneath the path of travel of the bed. The guide casting is provided beneath the pivot with an arm 119, to the extremity of which is pivoted at 121 a transferring lever l22 equipped at its other end with a transferring head 123 which is adapted to travel along the guide 116, the lever 122 being mounted concentrically with the guide. The guide casting is also extended beyond the receiving end 1180f the guide and is provided With a downwardly projecting cam shaped arm 124 disposed in the path of travel of a roller 125 carried by the arm 24 in front of the cam follower 25. When the arm 24 is swung to the left by the cam groove 26 in the drum 27 the roller 125 engages with the inclinedsurface of the cam arm 124 and elevates the guide 116, and with it the transferring lever 122 into alinement with a removed address form suspended between the plate 107 and the finger 112. Continued movement of the arm 24 to the left, viewing Fig. 4, will move the lever 122 to the left about its pivot 121, through the instrumentality of a link 126 pivoted at one end to the arm 124, provided with a slot 127 which is engaged with a pin 128 on the lever 122. After the guide has been raised, as above described, continued movement of the lever 24 to the left will bring the inner end of the slot 127 into engagement with the pin 128 to thereby swin lever 122 about its pivot along the guide 11 to transfer the address form from suspended position between the plate 107 and finger 112 along the curved guide 116 into the upper end of the tray 115. A packer arm 129 pivoted at 131 extends into the tray adjacent the delivery end of the transferring guide and is provided with an arm 132 carrying a roller'133 which engages with a cam surface 134 on the side of the contiguous roller or flange 39 to swing the arm 129 to the right, viewing Fig. 4, about its pivot and thereby push the delivered address forms downwardly in the tray. A contraction sprlng 134 attached at one end to a pin 135 on the rigid arm 136 which supports the transferring mechanism and at its other end to the arm 129 returns the arm to normal position after each actuation thereof.

From the foregoing it will be understood that I have provideda printing machine adapted to print form letters in close simulation of typewriting and to provide each letter with a difierent address and salutation. The address forms are transferred from a magazine to the bed of the machine upon the return stroke of the bed, a section of the bed is elevated to form a rigid support for the address form during the printing operation, the address form is removed from the bed at the completion of the printing stroke and upon return movement of the bed from beneath the address form this form is transferred to a tray or other suitable container in which the forms are packed.

It is believed that my invention and its mode of operation will be sufficiently understood from the foregoing without further description, and it will be obvious that the mechanical details illustrated and described are capable of considerable variation and modification within the purview of my invention and without departing from the true-scope of the invention as set forth in the following claims.
