April 9 1933- R. M. DUGDALE L8L596 PRINTING DEVICE Filed June 21, 1930 Patented Apr. 21, 1931 UNITED STATES 1 PATENT OFFICE RICHARD M. DUGZDALE, OF DEDHAM, MASSACHUSETTS, ASSIGNOB 'I'O FARRINGTON MANUFACTURING COMPANY, OF BOSTON, MASSACHUSEFI'S, A CORPORATION 01' MASSACHUSETTS PRINTING DEVICE Application filed June 21, 1930. Serial No. 482,784.

This invention relates to printing devicesoperating with customer-carried tokens havof the type adapted to print from individual printing plates such as are employed for example in identifying charge customers in 5 department stores. Such printing plates, which comprise the subject matter of my copending application, Serial No. 374,715, filed June 29, 1929,,preferably comprise a sheet of thin metal having a struck-up typehearing central portion surrounded by a depending flange. These sheet metal plates are formed from sheet metal blanks by a stamping operation, and are thin so that the type characters may be embossed thereon.

The printing device adapted to use these plates includes a plate holder shaped to interfit with the plate, for instance by the provision of recesses within which the flanges of the plate may fit, or the provision of a supporting member extending into the struck-up recess between the flanges of the plate. Because of the thin sheet metal of which they necessarily must be made, the or various printing plates which cooperate from time to time with a given printing machine may exhibit irregularities in the efi'ective heights of certain of their type'characters, 'due for example to irregularity in em bossing the type characters, or to slight malformation of the opposite longitudinal.

flanges of a plate. Thus a row of type characters on one'part of the plate may extend to a greater height than those on the other M part of the plate when the plate is in printin position within the printing device. Furthermore the surface of the printing characters of a given line of type may not extend to the same height throughout the length of the line. In such case the lower line of printing characters of a plate at one end of a plate may extend to the greater height, while at the opposite end of the plate the upper line of printing characters may extend to the greater height.

One object of my invention is to provide printing devices capable of producing uniform legible impressions from-such imperfect plates and more particularly to provide a device suitable for use in printing names and addresses on sales slips and capable of ing the imperfections described above. Other advantages, objects of invention and structural improvements will be apparent from the explanation in this specification and its accompanying drawing of a specific illustrative embodiment of my invention.

For the purposes of illustration and by way of exam le my invention will be explained by re erence to its embodiment in a device ofv the type claimed in m copending application, Serial No. 404,290, led November 2, 1929.

Referring to Fig. 3 a thin sheet metal printing plate 31, such as disclosed in aforesaid application Serial No. 374,715 and suitable for use in the device of the present invention, includes a central struck-up portion having thereon lines of type characters 33 which may spell in direct order the name and address of a customer who carries the plate. A depending flange 34 (Figs. 3 and 4) preferably extends completely around the central type-bearing portion of the Plate, this conformation of the plate performing the dual function of imparting strength and some rigidity to the ductile plate, and of 10 providing for the positioning of the plate in a rinting device.

he rintin device of Fig. 1 is provided with a ase indicated generally by the reference character 1 which includes a backing member 11 recessed at 37 (Fig. 2) to receive the depending flan e 34 of a sheet-metal printing plate 31. Fig. 4 illustrates a preferred interfittin relation of the sheetmetal printin p ate 31 and the backing member 11 which forms part of the base. As shown in Fig. 4, a central portion 39 of the backing member extends within the struck-u portion of the printing plate 31 and in tis interfitting relation the plate is retained with its type characters 33 in printing position, both by means of the engagement of the flanges 34 with the sides of the groove 37 (which act as raised guide members) and by the engagement of the outwardly facing shoulders of the central portion 39 of the backing member with the inwardly facing parts of the plate at the side of its struck-up central portion. However, the printing plates may be detachably retained In either of these ways, that is, solely by the engagement of their flanges 34 with the sides of the recess or by'the engagement of the outwardly facing shoulders of the central pro'ection 39 on the backing member with the inwardly facing parts of the plate at the sides of the struck-up central portion thereof. The plate, through thus positioned against horizontal displacement, may readily be removed vertically.

A casing 14 containing a pressure member, herein shown as a roller 15, and an ink ribbon 16 together with suitable ribbon advancing mechanism, is pivoted at 17 to the backing member portion of the base, and may be swung to the right in Fig. 1 to give access to the upper side of the printin plate retaining means for the insertion of the printing plate and the sheet or sheets to be printed. An operating handle 20 associated with the casing and pivotally mounted thereon at 20 serves to depress a vertical plunger 21 carrying a cam 22 at its lower.

end. A sleeve 80, fixed to the casing, is rovided with a depending extension or racket 81, which carries a transverse pivot pin 82 extending therethrough. Upon this pin 82 is pivotally mounted a bifurcated actuating arm 24, as shown particularly in Fig. 6. The arm 24 carries near its upper end a cam follower 23 adapted to engage with and be moved by the cam 22 mounted on the plunger 21. Thus depressing the actuating handle 20 causes the cam 22 to swing the bifurcated arm 24 about its pivot 82, to the left in Fig. 1.

Referring to Fig. 1 the casing 14 preferably is provided with an inner shell comprising a vertical back portion 100 and vertical side portions 101 and 102, this inner then be shell being fastened rigidly, for instance at its back portion 100, to the casing 14. The vertical side ortions 101 and 102 are spaced from the ad acent side walls of the casing 14 (Fig. 1) and are provided with inwardly directed curved ortions 101, 101", 102 and 10 2 which ena le these side portions 101 and 102 to serve as guides for the ink ribbon 16 between ribbonreels 2.

lteferring to Fi s. 1, 4 and 5, a channelshaped guide mem er having dependin vertical flanges 90 and 90 is provided wit vertically extending brackets 93 and 94 fast thereto. These brackets 93 and 94 are pivotally mounted by means of loosely fitting rivets 95 (Figs. 1, 4 and 5) to the side portions 101 and .102 respectively of the inner shell 101 of the casing. Thus the channelshaped guide 90 is capable of tilting about an axis parallel to its direction of length, for instance from the position of Fig. 4 to that of Fig. 5.

The pressure roll 15 is mounted within the channel-shaped guide 90 and is provided with journals 15" and 15", which engage and roll in slots 96 and 96 in the opposite flanges of the guide 90. The roll 15 is provided with an axially extending pin 97 which extends to either side of the guide 90 and engages loosely within slots 98 in the opposite branches of the bifurcated arm 24. In this way swinging of the bifurcated arm 24 by actuation of the handle 20, as explained above, serves to move the pressure roll 15 across the casing and over a printin plate retained by the base. B virtue o the pivotal mounting of the gui e 90 within the casing, the pressure roll 15 is ada ted to conform to irregularities in height 0 the various lines of type characters on a printing plate. The pin and slot connection between the roll 15 and the bifurcated arm .24 permits actuating movement of the handle 20 to be communicated to the roll 15 in any of the various tilting positions which the roll may assume.

In the operation of the device, the casing 14 is swung to the right in Fig. 1 to expose the upper surface of the backing member 11, and the typographical plate 31 is inserted with its flange 34 within the recess 37. A sheet of a sales book (or' a plurality of sheets with interposed carbon paper) may placed upon the upper surface of the printing plate with the main body of the book occupying the space between the backing member 11 and the remainder of the base. Then by swinging the casing 14 down to the position of Fig. 1 by means of the handle 20 and then further depressing the handle 20, the pressure roll 15 may be moved over the inked ribbon 16, the sheet or sheets to be printed, and the printing plate, thereby to reproduce the indicia of the plate upon the upper surface or surfaces of the sheet or sheets inserted in the machine. The guide 90 and the pressure roll 15 are free, as the pressure roll reacts with the printing plate, to tilt about an axisparalle to the direction of movement of the roll, so that uniformity of printing is obtained even in the case of non-uniformity of heightof the type characters of the various lines.
