Application JulyZ, 1941, Serial No. 400,732

(ci. i-277) 12 Claims.

This invention relates to a printing machine, and more particularly to a printing machine of the class in which a combined duplicating and printing impression may be made simultaneously. A preferred form of my invention will be shown and described in this specification through reference to structure which is shown but not claimed inmy copending applications Serial No. 357,555 filed on September 20, 1940 and Serial No. 164,725 led on September 20, 1937.

Combined duplicating and printing has been accomplished in prior art structures, and in the patent toMahlstedt No. L1,016,756 granted on February 6, 1912, there is shown a printing machine in which a ribbon duplicator operates in conjunction with printers type to yield a combined duplicating and printing impression. In Mahlstedt the inking mechanism for the printerfs type is located for cooperation with pre-determined end portions of the printing bed, and it is a feature of the machine that the central portion of the bed which carries the ribbon duplicator does not pass into cooperative relation with the inking mechanism. While therefore, Mahlstedt obtains a com,- bined ribbon duplicating and printing impression, his apparatus is inflexible, and it is impossible for him to vary to any considerable extent,`if at all. the relation and vlengths of the printing and duplicating portion of his impression.

It is a feature of my invention that the duplicated portion of the impression may be located on any part of the printed sheet yielded by my machine by merely placing the duplicating unit in a predetermined position on the type carrying portion of the machine. More specically, it is a feature of my construction that the duplicating type foi` inking the type, all of which will now be lfully appreciated. It will be understood by those skilled in the art that my invention is adapted for use in a cylindrical type carrying member without fundamental change and that my claims should be so interpreted. As still a further detailed feature of my invention, the control segments form part of the dupli* eating unit per se so that as the duplicating unit is placed in assembled relation to the. chase, the

control segments are automatically positioned for cooperation with the inking rollers to lift them out of contact with the duplicating surface.

While I have thus far indicated that my duplieating unit may bev of the ribbon type shown in the Mahlstedt patent, it is possible also to use a stencil duplicating unit such as that shown in the Hommel Patent No. 2,011,363, lissued Aug. 13, 1935, or in the Norman Patent No. 1,780,095

issued Oct. 28, 1930. In the drawings and in the is the same, whether it is of the ribbon 'or stencil unit of my invention is readily applied to any desired portion of the printing chase or the particular member that carries the type and duplicating unit, and that thereafter the duplicating unit controls parts of the machine, and more particularly the inking mechanism thereof.

An inking assembly which cooperates with type an inking assembly, and with the rollers of the inking assembly preferably of the class adapted to move vertically relatively to the inking assembly, all as set forth in my earlier application Serial No. 164,725. As a feature of my invention, Iutilize control segments which are co-extensive and, in effect, integral with the duplicaf4 1g unit, and Whiohmove the inking rollers relatively'to the 'plane of the duplicating unit as the duplicating unit passes under the inking rollers. Inthis way, the inking rollers are prevented from contacting the duplicating unit, while allowed to contact the type, all of which will be fully appreciated by those skilled-in the art.

It may be well to indicate that I consider my invention a broad contribution to the art and that I feel myself entitled to claims of sufficient scope to prevent the utilization by others of my inventio-n in physical forms different from that which I shall hereinafter show and describe. Such different physical forms will readily occur to those skilled in the art.

Referring now to the drawings, Fig. 1 is a vertical section of the printing press shown in my patent application No. 357,555 supra. Fig. 2 is an enlarged view of the inking unit with parts thereof broken away to illustrate the coaction between the inkingrollers, the type, and the duplicating unit. Fig. 3 is apartial section taken substantially along lines 3-3 of Fig. 2. Fig. 4 is a plan View of the chase of my printing machine and illustrating a stencil duplicating unit and type assembled relatively thereto. Fig. 5 is'a section taken substantially alongv lines 5-5 of Fig. 1.

Referring now more particularly to the draw- V ings and especially Fig. 1, my printing machine pivoted at l5 to the printing bed I6. It Will be Ving portion 2U.

appreciated that the rotation of the motor acts to reciprocate the bed I6, which in Fig.,5 is illustrated as mounted for sliding movement on the bearings I1 and I8 of the main frame I6 through its V-shaped bearing portion I9 and square bear- Y The chase of the machine is designated in Figs. 4 and 5 by reference numeral 2| and is shown in Fig. 5v mounted on the bed `I6 and latched in place by a hook 22 cooperating with the pin 23 of the chase. The type carried in' chase 2|, when the chase is reciprocated with the printing bed I6, is adapted to cooperate with an impression cylinder 25 and the inking rollers of an inking assembly 26 all as is set forth in my applications supra. While the inking assembly is not per se part-of the invention of this application, I deem it best to outline briefly its construction and operation.

The inking assembly 26 is best illustrated in Figs. 1, 2 and 5 to which reference will now be had. There it will be noted that the inking assembly comprises opposed main side plates 2'| suitably notched at 28 for cooperation with locater pins29 mounted on the main frame of the press. Spring pressed latch bolts 30 are mounted on the inking assembly and are con- Normally, the latch bolts 30 cooperate with bores 32 of the main side plates 33 of the printing press for latching the inking assembly 26 into the position pre-determined by the locater pins 29 and the notches 28.

The inkin'g assembly may comprise an oscillator roller 34, and a series of inking rollers 35, and

' the form rollers 36 which are adapted to contact the type 38 carried by the chase 2 I. As more particularly set forth in my application No. 164,725, the several inking rollers are mounted on shafts 35a while the form rollers are carried on shafts 36a. These shafts 35a and 36a are mounted in bearing blocks 31 relatively to which the shafts rotate with inking rollers 35 and form rollers 36. The bearing blocks 31 are in turn mounted for vertical sliding movement within the arcuate slots 39 formed in the main plates 21 of the inking assembly 26 and are adapted normally to occupy positions in the slots probably best illustrated in Fig. 5 in which the form rollers 36 are shown lying against the type 38 carried in the chase 2|. The bearing blocks 31 together with the inking rollers 35 and the form rollers 36 are adapted to move vertically through operation of certain control segments which I have described generr ally heretofore, and will describe more particularly hereinafter.

In addition, as is set forth in my earlier application No."164,725, the inkingrollers 35 and the form rollers 36, are adapted not only for vertical upward movement, but for a separation relatively to one another, by rotation of the'knob 40 and subsequent vertical movement of the cross bar 4I and inside separation plates 42. This arrangement is set forth and claimed in my application Serial No. 164,725 supra.

Referring now'more particularly to Fig. 4 the chase 2| is shown as housing a stencil duplicating unit 44 which may be of the type shown in the Hommel and Norman patents referred to supra As here shown, it comprises a shallow depressed chamber in which is contained ink which is suitably fed to the under side of the duplicating stencil, all as will be well understood by those skilled in the art. Alsozthe duplicating trol segments 45 and 46 which are preferably adapted to overlie the side bars 41 and 48 of the chase 2|. Printers type 38 may also be set into the chase 2|, with the type and duplicatingI unit held in position by suitable furniture 5I and quoins 52.

It will now be readily appreciated that -the duplicating unit 44 may be assembled in any longitudinal position relatively to the chase 2| and relatively to the type 3B. When the duplieating unit is assembled relatively to the chase 2 I, the control segments 45 and 46, which are secured directly to the duplicating unit, are automatically adapted for cooperation with the flange rolls 54 secured on each end of each shaft 36a and rotatable with the form rollers 36 as best illustrated in Fig. 3. This cooperation is the same regardless of the selected position of the duplicating unit in the chase, and i's completely accurate, as will be understood. Fig. 5 illustrates the flange rolls 54 when the form rollers 36 are in contact with type 38 as when there is no stencil or other duplicating unit 44 within the chase 2|. Fig. 3 illustrates the coaction between one of the flange rolls 54 and a control segment 45 of the duplicating unit 44. It will be noted that the control segments coact with the flange rolls 54 to move the form rollers 36 vertically, which movement is possible through the mounting .of the form roller shafts 36a in the bearing blocks 31 that are slidable Within the arcuate slots 39 of the main plates 21 of the inking assembly 26. Y It will now be appreciated that when the duplicating unit 44 is under the form rollers 36, those form rollers Vare elevated out of the plane of the stencil of the duplicating unit, .and that this elevation is dependent merely on the position of the duplicating unit in the chase. Obviously there can be no error on the p art of the operator of the machine, since the mere placing of the duplicating unit `in the chase automatically determines and controls the operation of the inking rollers. It will be also appreciated that when the duplicating unit leaves a position under the form'rollers 36, the form rollers are adapted to drop on to the type 38. Thus in Fig. -2, that form roller 36 at the left of the drawings' is shown in contact with the type 38. The flange rolls 54 of that form roller 36 to the right ofthe type contactingroller 36 are shown in contact with the control segments 45 and 46, and therefore holding the particular form roller 36 out ofthe lplane of the stencil of the duplicating vunit 44.v It is thought that those skilled in the art will now fully appreciate the significance and operation of my invention and the broad contribution I have made, and which contribution Amay be utilized in juxtaposed relation vto said bed and having form rollers lying normally in the plane of typev carried by said bed whereby to apply ink to said type, means mounting said rollers for movement relatively to said inking assembly and out of the plane of said type, control lflanges for said rollers through which said rollers aremoved out of the plane of said type, a duplicating unit adapted for mounting on `said bed with its duplieating surface substantially in the plane of said type, and surfaces formed functionally as an integral part of said duplicating unit for contacting said flanges for moving the rollers out of contact with said duplicating surface as said duplieating unit passes under said rollers- 2u.
