21 Claims.

- This invention relates to printing machines andmore particularly to structural sections adapted for use therein.

In printing machines of the character through which printing or like devices are sequentially fed, it is customary to feed the devices through the machine in a step-by-step manner and in the course of such movement the devices come to rest in printing position in the machine whereat impressions are made therefrom. While a wide variety of printing devices, of the character sequentially fed through printing machines such as those to which the present invention pertains,

have heretofore been provided, that disclosed in Mohler Patent No. 1,812,894, patented July 7, 1931, is typical of such devices. A printing device of this kind includes a carrier or frame having an embossable metal plate removably retained in position thereon, type characters being embossed on such a plate to appear in relief on the operative face thereof. Type characters have also been embossed in a so-called one-piece printing device of the character disclosed for example in Duncan Patent No. 1,026,246, patented May 14, 1912, and devices of this character are frequently utilized in printing machines of the kind to which this invention relates. Furthermore, in some instances type characters have been formed in suitable stencil paper, carried by a frame of cardboard or other material, and suitable means have been provided in printing machines through which such devices were fed to apply ink to the. type characters on printing devices of this character and for pressing a sheet into engagement with the inked type characters to thereby have an impression made thereon. Irrespective of whether printing devices embodying embossed type characters, or type characters afforded in a stencil sheet, were utilized, it has been necessary, in printing machines through which the devices were passed, to apply appreciable pressure in order that clear cut and otherwise satisfactory impressions would be produced in the machine.

In the printing machines through which printing or like devices of the aforesaid character, for example, are sequentially fed, the printing devices, in the course of the step-by-step movement thereof through the machine, come to rest at printing position in the machine on an anvil beneath an ink ribbon and a platen or other suitable means is operated to force a sheet overlying the ink ribbon toward type characters on the device whereupon an impression is made on the sheet from the type characters. Heretofore flat ing machines of the aforesaid character.

and roller platens have been employed in' print- A flat platen of this character has customarily included a head embodying a flat face of resilient material, the head having been carried by an arm which was reciprocatedto move the flat resilient face on the head to and from the operative position whereat impressions were made from the printing device at printing position in the machine in the aforesaid manner. A typical roller platen such as hasbeen heretofore employed has included a resilient periphery and has been so mounted in the machine that it wasmovable to and from operative cooperation with a printing device on the anvil and customarily such a platen has been rolled across the type characters on the printing device on the anvil to effect a printing operation.

Heretofore it has been custom yv to mount the anvil, or other means on which the printing devices come to rest during the time impressions are made therefrom, on the frame of the machine and to also mount the platen, or other means operative to press the sheets into engagement with the type characters on the printing device resting on such an anvil, on the frame of the machine. In such an arrangement the stresses attendant to the application of pressure to effect the printing operation have been transmitted through the frame of the machine. This has necessitated that such frames be of rigid construction so as to be capable of dissipating the stresses attendant to the printing operations without undue deflection occurring in the various operative parts. This has also required that the operative parts themselves be constructed so as to effectively resist material deflection. It will be appreciated that deflection in the frame of printing machines or in the parts operative to effect printing operations in such machines might result in smudging the impressions, or in the production of uneven impressions, which is to say, the making of some parts of an impression heavier than other parts, and material deflection is objectionable for other reasons.

In those instances where embossed type characters have been provided on printing devices of the character that are sequentially passed through printing machines of the kind to which this invention pertains, the type characters are customarily arranged in rows that extend across the devices transversely to the'line of movement thereof through the machines. Moreover, where roller platens have been employed for making impressions from type characters arranged in this manner, the axes of the roller platens have extended in substantially parallel relation with the extent of the rows of type characters. Frequently the rows of type characters afford an arrangement from which a name, street and number, city and state or the like constituting an address may be printed and it will be appreciated that in such an arrangement the length of various rows of type characters will vary. For example, the name may be relatively short, the street and number may be relatively long, and the city and state may be of a length intermediate the length of the name and thelength of the street and number and, of course, other wide variations in the lengths of the lines may occur. Thus, particularly where a roller platen is employed for making impressions of the type characters so arranged and the roller is caused to move across the devices so as to advance from one line to another, there may be a tendency for the roller platen to make heavy impressions from short lines and lighter impressions from long lines of 'vices of the character sequentially fed through printing machines, be so arranged that material deflection in the parts in the course of impres-- sion operations in the machine will be avoided and an important object of this invention is to so arrange the parts operative to make impressions from printing devices in printing machines that objectionable deflection therein in the course of impression operations will be prevented.

Sufiicient rigidity soas to avoid objectionable deflection may of coursiejbe imparted by forming the parts to include sufficient material to resist objectionable deflection but where castings, forgings ,or conventional structural sections have been employed for this purpose, it has been necessary to make the parts quite heavy and this has been objectionable because it is advantageous to have printing machines of the aforesaid charactar as light in weight as is consistent with emcient operation and the use of relatively heavy sections is objectionable from a cost standpoint and for other and kindred reasons.

Thus, still another important object of this invention is to so arrange the parts entailed in the performance of impression operations in printing machines that objectionable deflection in such parts in the course of impression operations effected thereby will be prevented but at the same time to construct such parts so as to be as light as will be possible consistent with emcient and proper operation.

It has been mentioned hereinabove that it isobjectionable to transmit the forces attendant to impression operations in printing machines of the aforesaid character through the frames of such machines and in view of this it is another object of this invention to so arrange the parts entailed in the performance of impression operations in printing machines that the stresses attendant to the performance of such operations will not be transmitted through the frame of the machine in which the impression operations are effected and an object ancillary to the foregoing is to arrange the support on which the printing devices rest during impression operations, and the means for applying the impression producing pressure, in a unitary member in which all the forces attendant to the performance of impression operations will be absorbed and dissipated.

More specifically it is an object of this invention to support an anvil on which the printing devices may rest while impression operations are performed thereon in a unitary structure, also affording a support for the platen or other member employed for applying the impression pressure.

While it is essential that such deflection as might impair the production of clear cut and otherwise satisfactory impressions in the parts entailed in the performance of impression operations in printing machines be avoided, it is at the same time desirable that some deflection be afforded so as to compensate for variations in the thicknesses of sheets or the like on which the impressions are made and thus yet another important object of this invention is to prevent such deflection in the parts entailed in the performance of impression operations in printing machines as may impair the production of satisfactory impressions and yet at the same time afford as much deflection as may be required to afford such compensation, for variations that may be encountered, as may be needed.

In order that the foregoing and other and kindred objects of this invention may be realized, I utilize sheet metal plates and I so form, arrange and join these plates that supports for both an anvil or the like and a platen or other pressure member are afforded in the unitary structure made from such plates.

' for the parts entailed in the performance of such operations and an object related to the foregoing is to weld together metal plates formed and arranged in a selected manner so as to thereby afford a novel unitary structural section.

While the present invention is particularly useful in printing and like machines, it is to be understood that the structural section to which this invention primarily pertains will be useful in other machines such as, for example, punching machines and presses and in other instances where it is necessary to dissipate stresses attendant to the production of opposing forces and thus while the present invention is described with particular relation to printing machines of the character through which printing devices are sequentially fed, it is to be understood that while this is the preferred it is not the sole embodiment of the present invention and that therefore the invention is not to be considered as being limited to use in printing machines of the aforesaid character.

Other and further objects are to so form metal plates that, when such plates are joined into a unitary structure, maximum resistance to deflection will be afforded; to so form plates, as aforesaid, that interconnection along abutting edges thereof may be effected by welding the plates together to afford a unitary structure: to so incorporate an anvil or the like and a platen arrangement or the like in a unitary structure that what may be called a printing frame will be afforded; to so form and relate the metal plates of such a printing frame that bearing means for operating shafts for operative parts on theline 3-3 on Fig. 1;

lines 2545, 26-46, 21-21 and2828 on may be extended therethrough without reducing the structural rigidity of the frame; and to so form and relate the metal plates of such a structure that the assembly and welding operations may be readily and easily performed and efficiently inspected upon completion of the frame.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show a preferred embodiment and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle. Other embodiments of the invention embodying the same or equivalent prin- I ciple may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

The machine illustrated in the accompanying drawings in which the novel printing frame of this invention is utilized is described in detail in my co-pending application, Serial No. 388,998, filed April 17, 1941, and reference may be made to this application for a detailed description of the various, operative parts .of the machine. Briefly, however, this machine includes a table top T on which sheets such as envelopes. letterheads, bill forms, ledger sheets and the like may be arranged to receive impressions from printing devices or the .like sequentially fed through the machine, the devices being introduced into the magazine M and being successively withdrawn from the bottom of the stack thereof in the magazine by the arrangement described in detail in my co-pending application, the printing devices being advanced through the machine in a step-by-step manner and in the course of such movement coming to rest in operative relation with the platen P to have one or more impressions made therefrom upon operation of the platen. At the time the printing devices come to rest in operative relation with the platen P,

they are disposed. on an anvil A which, along with the platen P, is carried by the novel printing frame of this invention.-

The platen P is preferably a so-called roller platen and while this platen may be operated in a wide variety of ways, an advantageous way of so operating this platen is described in full detail in my co-pending application, Serial No. 361,530 filed October 17, 1940. In the present instance, however, the platen P is carried by a carriage C having supporting and guid ng rollers thereon which travel on tracks 52 provided en the carriage support plate 53 adiustably connected to the platen head forging 54, described more fully hereinafter. The carriage plate 53 is connected to the head 54 for vertical adjustment movement which is effected by an adiusting knob 55, and by rotation of the knob 55 it is possible to vary the pressure exerted by the platen P in the course of rotation thereof. The

- particular manner in which this adjustable interconnecticn is afiorded is described in full detail in myaforesaid co-pending application, Ser. No. 361,530, this adjustability also enabling the platen P to be adjusted relative to the printing devices which come to rest on the anvil A so as to insure that the platen will uniformly cooper- 5 ate with type characters afforded on the printing devices so as to produce uniform impressions.

In the course of operation of the machine, the shaft 60 is set in operation and through the intermediary of an eccentric 6| thereon is operative through the adjustable link 62 to rock the arm 63 fast on a shaft 64 mounted in a manner described in further detail hereinafter. The shaft 64 also has an arm '65 thereon at the end there of opposite that at which the arm 63 is mounted, 15 and a link 66 is pivotally connected to the free end of the arm 65, the opposite end of this link being pivotally connected to the free end of an arm 61 fast on a shaft 68 mounted in a manner described in further detail hereinafter. At the end of the shaft 68 opposite that at which the arm 61 is fast, there is an arm 69. The arm 69 has a transverse pin fixed therein at its free end throughwhich an operative connection is provided to the platen carriage C. Hence, 'in the course of operation of the shaft 60, a reciprocatory movement along the platen support 53 is imparted to the carriage C. In the course of this 7 reciprocatory movement means described in detail in my aforesaid co-pending application, Ser. No. 361,530 are effective through the toggle 1I to lower the platen P into operative relation withthe printing device resting on the anvil A, and in the course of reciprocation of the carriage C, after the platen P has been lowered into operative relation with a printing device, an impression is made from the type characters on the printing device onto a sheet disposed beneath the platen P, an ink ribbon (not shown) being interposed between type characters on the printing device and said sheet.

The printing frame I00, which is the novel structural section to which this invention primarily pertains and one which the anvil A and the platen P are mounted, is mounted on the main supporting frame IOI of the printing machine, which main frame also carries the table top T. As shown in Fig. 1, the printing frame I is associated with the rectangular table top T so as to extend diagonally with respectthereby. The frame IN is formed to provide a pair of supporting rails I02 and I03 that extend parallel to the front edge of the table top T, these supporting rails being employed in mounting certain of the operative parts of the printing ma- 55 chine and also serving as the support for theprinting frame I00.

The printing frame I00 is of a generally 0- shaped' configuration and includes an upper arm or section I05 and a lower arm or section I06 which project in a generally parallel relation from a vertical portion I01 therein. The vertical portion I01 of the printing frame extends through the table top T adjacent the right rear corner thereof, as shown in Fig. 1, so that the upper arm I05 extends diagonally across the ta-' ble top T in upwardly spaced relation with respect to the table top, while the lower arm I06 extends beneath the table top T and in the complete machine is concealed and housed within the frame I0l.

In the course of operation ofthe machine, the force required to effect the desired printing operation is applied between the anvil A and the head forging 54 through the extension of the.75

toggle mechanism II of the platen, and this force is so applied that the tendency is to separate the opposed arms I05 and I06 of the printing frame I00. The printing frame I00 is therefore constructed to resist such separating effect of the force which is thus applied between its arms I05 and I06, but at the same time, I have so formed the printing frame that it has a pleasing appearance suitable for incorporation in a printing machine of the character herein and also as to avoid the necessity for further housing or concealing of unsightly parts.

In attaining the foregoing, the printing frame I00 is constructed from a plurality of independently formed parts most of which are made from sheet metal or sheet steel stock, these independently formed parts being thereafter assembled and then securd in the desired rigid relationship by welding. The desired rigidity is also in some instances assured by mechanical interlocking of these separately formed elements.

The several separately formed elements which enter into the production of the printing frame I 00 are shown in an exploded relationship in Fig. 10 of the drawings, the parts being shown in this view in such a way as to indicate the relationship therebetween in the completed printing frame I00. Thus, as shown in Fig. 10, a central plate H0 is provided, which is generally 0- shaped in form so as to provide an upper arm H5 and a lower arm II6 connected by an integral intermediate vertical portion I I1. This central plate H0 is adapted to be enclosed within or between two shell-like members I20 and I30 which are adapted to be placed on opposite sides of the central plate III! with the edges of the shell-like members I20 and I30 substantially registered with the bordering edges of the central plate II0.

The shell-like member I20, which will hereinafter be termed the left-hand shell member, has an upper arm I25, 2. lower arm I26 and an intermediate vertically extending connecting portion I21. The arms I25 and I26 and the vertical portion I21 of the shell-like member I20 are generally channel-like in cross section, as

will be seen from a comparison of Figs. 5, 10 and l 31', this channel-like form being such that the width of the channel, that is, the width of the web thereof, varies in the extent of the arm I25 so as to be considerably wider at the rear end of the arm I25. Similarly the web of this chan- 4 nel is relatively wide as it extends through the length of the vertical portion I21 of the shelllike member I20 and the width thereof gradually decreases" from the rear end of the arm I26 toward the forward end thereof. Thus, the channel-like form of the arm I25 is provided by a web portion I25W having upper and lower flanges I25 and I25" extending from the upper and lower edges of the web I25W. As shown in Figs.

5 and 31, the flanges I25 and I25" diverge slightly so that the open face defined by the edges of the flanges I25 and I25" is at all points along the arm I25 slightly greater in width or vertical dimension than is the web I25 at the corresponding point along the arm.

At the rear end of the arm I25, the web I25W merges with an integral web I21W of the vertical portion I21, and the rear portion of the upper flange I25 merges with a flange I21 which forms the rear flange of the vertically extending portion I21. The two flanges I25'-and I21 are preferably merged through a curved rear corner,

as indicated at I40.
