This invention relates to a device for printing names and addresses or other indicia on sales slips or the like and has f or its principal objects the provision of a device for use by department stores and other establishments which avoids the many mistakes ordinarily resultin from illegible and inaccurate writing o names and addresses'by sales clerks, which facilitates identification of charge customers by the use of a printing plate vcarried by the customer for printing the sales slips, which avoids all tendency to soil the printing plate with ink in the pilinting process so that the plate may be freely handled and carried in a purse without soiling the hands or purse contents, which clearly and sharply prints any reasonable number of carbon copies, which requires little effort in manipulation so that it may be used by sales girls with facility, which is sufficiently light and compact to be readily portable if desired, which may be arranged to open automatically for the insertion'of ,the printing plate and sales slips or the like in the normal and natural manner of lifting the device by the operating handle, which ma be used with ink sheets of either the rib on type or carbon sheet type, which facilitates the insertion of the printing plate, which permits the use of a printing plate having the indicia in non-reversed order for ready reading, and which is generally superior to prior devices for similar uses.

PRINTING DEVICE Serial No. 359,816.

Fig. 10 is a section on line 10-10 of Fig. 9; and

Fig. l1 comprises two views of one of the ribbon reels.

The particular embodiment of the invention shown -in Figs. 1 to 5, and 9 to 11 inclusive, comprises a casing 1 having its lower end open, a plate holder 2 pivoted to the casing at 3 to swing from the closed position shown in Fig. 1 to an open position such as shown in Fig. 6, an inner casing 4 welded or otherwise mounted on the inner face of the back of the outer casing 1 and having two integral' flanges 5 extending forwardly at right angles to serve as ribbon guides, theV upper and lower ends of these flanges being bent inwardly as shown in Fig. 1, a horizontal guide bar 6 welded or otherwise' mounted on the flanges 5 and/or the back of the casing 4, a roller carriage 7 which is U shaped in cross section, as shownin Fig. 2, and which has a longitudinal opening to receive guide 6, rollers 8 journalled in the depending flanges 9 of the carriage, a cam 10 extending upwardly from the top of the carriage 7, a spring 11 yieldingly urging the carriage to the right (Fig. l) and actuating Y mechanism cooperating with the cam 10 to move the carriage to the left against the action of the spring 11. v

The particular actuating mechanism illustrated in Figs. l, 2 and 3 comprises a plunger 12 sliding in a tubular extension 13 extending upwardly from the casing 1, a cam roller 14 journalled in the lower end of the plunger in cooperative relationship with the cam 10, a .pin 15 fast in the extension 13 and extending through a slot in the plunger 12, a second plunger 16 sliding in a guideway in extension 13 parallel to the guideway of the plunger 12, a pin 17 interlocking the two plungers together and aspring 18 normally holding the plungers in uppermost position.

When using an ink ribbon the referred mechanism for supporting the ribbon is illustrated in Figs. 1, 9, 10 and 11. This mechanism comprises two stud shafts 19 4 loosely to receive a ratchet wheel 22 and a spacing Washer 23. The ratchet wheel 22 has pins 24 projecting forwardly therefrom immediately outside the eriphery of the flange 21 on the shaft 19. he inner casinor 4 is provided with a recess 25 immediately lbJelow each of the reel supports and a spring 26 is mounted on the inner casing 4, by means of struck-up ears 35 (Fig. 9), to extend into the recess 25 and bear against the spacing washer 23 frictionally to retard rotation of the ratchet wheel 22 around the shaft 19. The forward ends of the shafts 19 are provided with grooves 27 to interlock with bayonet slots 28 on the front cover 29, so that the ribbon reels are held on the shafts 19 by the front cover 29 when the c over is ap lied to the casing 1 as shown in Flg. 6.

'Phe ribbon reels are preferably constructed as shown in Fig. 11, comprising a tubular part 30 having radial flanges 31 and 32 at the opposite ends, the rear flanges 32 having teeth 33 struck rearwardly therefrom to interengage with the pins 24 on the ratchet wheels. As shown in Fig. 3 the ratchet wheels have their teeth reversed with respect to each other so that the ribbon 34 is fed in one direction across the bottom of the casing 1 when one ratchet wheel is rotated, and in the reverse direction when the other ratchet wheel lis actuated. The preferred mechanism for actuating the ribbon reels is shown in Figs. 1, 2 and 3 and comprises pawl means in the form of a tumbler 36 pivotally mounted on the lower end of plunger l2 by the same pin 37 which supports the cam follower 14. Pivotally mounted on the back of the tumbler are two pawls 38 for actuating the two ribbon reels respectively. Pivotallymounted on the forward face of the tumbler 36 are two rollers 39 for engagement with the periphery of rolls of ribbon on the two reels respectively. The tumbler 36 is movable from a central position to either of two operative positions in which the pawls 38 cooperate with the ratchets 22 respectively. A spring 40 is mounted on the inside of the inner case 4 in cooperative relationship with a lug 41 on the tumbler 36 to snap the tumbler from the central position into either of its operative positions and yieldingly to hold it in either of the latter positions.` As shown in Fig. 1, the tumbler is in the right-hand operative position (left-hand position when viewed from the rear as in Fig. 3) to actuate the right-hand ribbon reel, the right-hand pawl 38 engaging the right-hand ratchet 22 to feed the ribbon one step to the right each time the plungers 12 and 16 are returned to raised position by the springs 11 and 18. When the roll of ribbon on the actuated reel reaches a predetermined diameter, it moves the adjacent roller 39 sulliciently to snap the tumbler into the other operative posltion,

whereupon the feed of the ribbon is reversed.

While any one of a great variety of printing plates may be employed with this device, a suitable form comprises a pressed metal plate P, such as shown in Figs. and 5, which has the indicia embossed in its central raised portion. This plate fits into a recess in the upper side of the plate holder 2 and may either rest in the recess by gravity or be eld by a. friction or positive catch. As shown in the figures, the rear edge of the plate frictionally engagesin a groove 42 at the rear of the recess.

The modification shown in Figs. 6, 7 and 8 is similar to that shown in the remaining Iigures except in two respects. place, the plun er 12 is actuated by a lever 43 pivoted in t e upper end of the plunger at 44, and having its short end pivotally 1nterconnected with the casing by a link 45. In the second place each of the rollers 8 are .journalled in a separate U-shaped support 46, which extends over a block 47 hav- Ving a recess to receive the guide plate 6.

The sides of the block 47 are milled to proide grooves for the depending portions of the U-shaped supports 46, to permit vertical movement of the rollers and supports relative to the block 47.' A rubber block 48 is provided above the horizontal portion of .each roller support. A plate 49 extends across the top of the rubber blocks and is secured to the block`47 by means of screws as shown at 50 in Fig. 6. The cam l10' is mounted on the' top plate 49. Thus each roller is independently movable in a vertical direction and is yieldingly held in the lowerv -tending into the groove 42 where it is frictionally held in position due to the resiliency of the sheet metal plate. Sale slips or other sheets to be printed are then positioned over the printing plate, which is rested on a table or other suitable support, and the casing is then swung downwardly to the closed position, shown in Fig. l. The printing is then effected by .depressing the handle to cause the rollers to move back and forth across the sheets. Ordinarily one complete reciprocation back and forth is sullicient so that the closing of the space between the casing and plate holder, the movement ofthe car- In the first v riage back and forthand the opening movement of the casing can be effected by a single continuous downward and upward movement of the handle. The downward movement of the handle not only serves to reciprocate the carriage but also forces the pressure means (the rollers in the illustration) and the impression means (the printing plate) together to compress the sheets therebetween. Inasmuch as the sales slips are ordinarily attachedat their upper ends to a pad holder, the plate holder 2 is preferably rounded at its left-hand end as shown in Fig. 7 so that it may readily be inserted under the sheets to be printed by lifting these sheets slightly from the remaining sheets of the pad.

It will, of course, be understood that the uppermost sheet is printed by the ink ribbon 34 and that any number of underlying sheets may be printed by inserting carbon sheets therebetween in the usual manner. By locating the printing plate on the side of the sheets opposite the ink ribbon, the plate contacts with neither ink ribbon nor carbon sheets, and is therefore not soiled in use, so that it may be handled and carried in a purse without danger of soiling the hands or purse contents.

From the foregoing it will be evident that the unique relationship between the plate holder and the pressure means not only avoids soiling the plate with either ink ribbon or carbon paper but also facilitates the insertion and removal of the printing plate. By using roller pressure means the impression is sharp and clear, even with a considerable number of carbon copies; and in this connection I have found rollers of hard fiber composition to be superior, although bakelite and other materials are suitable for many purposes.

'From the foregoing it will be evident that the printing pressure is approximately proportional to the resistance of springs l1 and 1,8 and is largely independent of the preslsure applied to the handle inasmuch as the downward pressure between the rollers and printing plate increases until the force applied to the handle is suiici'ent to overcome the resistance of the springs, whereupon the rollers start to roll over the slips, thereby preventing the printing pressure from further increasing. Thus excessive force applied to the handle merely results in quicker movement of the rollers across the slips without damaging the printing plate or causing the raised letters to cut through the slips. This action may be more readily apparent when it is considered that if the springs be removed the slightest downward pressure on the handle would move the rollers across the slips without any substantial component of force downward to compress the slips between the rollers and printing `plate. v
