Patent No. 1,543,066, June 23, 1925. `An ink ribbon 3 is carried by spools or spindles 4 mounted in bearing plates 5 at each end of a skeleton frame formed by bars 6 connected at their ends with the bearing plates and supported on the shoulders 7 on the main frame. The construction is such vthat the ribbon frame'may be lifted from the main frame and reversed end to end whenever it is desired to reverse the ribbon or for any other purpose. The ribbon spools carry ratchet wheels 8 on opposite ends for intermittently feeding the ribbon as will be described hereafter. A carriage 9 is mounted for reciprocation on the side bars 10 forming part of the carriage frame 11 which is pivoted at 12 to the main frame, Fig. 1. The front end of the carriage frame is detachably secured to the front end of the main frame by adjustable fastening devices 13 so that the carriage frame may be released to permit it to be swung on the pivot 12 and give access to the ribbon and forms and bed. A shield 14 is arranged on the frame to cover the front ribbonspool and the front portion of the shield is cut out as indicated at 14. This shield is pivoted at 15 to the frame so that it can be swung to open position when the carriage frame is swung to open position to give access to the front ribbon spool. 16 at each end ofthe carriage travel on the side bars 10, Fig.`3, to support the carriage on the carriage frame and grooved guide rollers 17 Vengage the tapered lower edgeslS of the side bars to guide the carriage and maintain it in proper transverse position above the bed. A platen roller 19 is mounted Carrying rollers ioo in eccentric bearings 20' which are mounted 1n boxes 21 slidably arranged 1n openings 22 in the carriage, Fig. 4. Arms 23 rigid with the bearings 20 are connected by links 24 with the handle 25 and this handle is swung by links 26 from projections 27 on the carriage, Figs. 4, 5. The construction is such that when thegcarriage is pushed forward from initial position shown in Fig. i the platen roller will be moved down into impression position upon a sheet to be printed laid upon the ink ribbon and when the carriage is pulled on its return stroke to initial position the platen roller will be lifted out of impression position so that the printing operation takes place on the forward pushing movement of the carriage from initial position, Fig. 1. Adjusting screws 28 are provided in the carriage for adjusting the bearing boxes for obtaining the desired ad- `justment of the platen roller for the work.

A dog 29 pivoted on the carriage at 30 and held in operating position by spring 31 is arranged to engage one of the levers 32 pivotally mounted at 33 on bearing plates 5 at opposite ends of the ribbon spools and operatively engaged with feed pawls 34, Fig. 1.

The lever 32 is arranged in the path of movement of the dog 29 on the carriage so that on the return movement of the carriage and just before it reaches initial position the dog will j swing the feed lever 32 to operate the feed do l34 to'engage the ratchet 8 and turn the 'bien spool a tooth, thus feeding the ribbon the distance of a ratchet tooth on each return stroke of the carriage. Since each spool is provided with

ribbon feedl devices

8, 32 and.

` l 34 the feed of the ribbon will be provided for whenever the ribbon frame is changed end for end. A sheet holder 35 is slidably mounted on a supporting pin 36, Figs. 2, 3 and upon an adjusting screw 37 whereby the holder` may be movedtransversely of the machineto `deliver sheets to be printed proper printing position. VThe sheets .38, Fig. 4, are sup- -ported in the holder on a bottom shelf 39 and they are held by a baiile` 40 which is pivoted` at 41 on the holder and is provided with a` lever 42 whereby the spring '43 normally holds the bae against the sheets as-'shown in Fig. 4 but the bae may be swung for- Wardly against the tension of spring 43 by operating lever 42 to permit the holder to bel reloadedv with sheets. To feedAV a sheet for printing the front sheet in the holder is lifted manually until it clears the baile and is then released to slide down over the baile and the guide bar 44 into position between the pressure roller 45 and the platen roller 19. As the carriage is pushed rearward on the printing. stroke the sheet is engaged between the platen roller and the feed roller and is laid down in printing position on the ribbon.

To provide for the use of changeable'printing devices for addressing letters to be printout movement of the slide.

terraces ed or for carrying other printing forms and for other purposes l provide a slide 46 whichis slidably mounted in guides 47 eX- tending ltransversely of the frame. rlhis slide has a slot 48 to receive a bar 49 which is attached to the bottom of an anvil 50 adapted to receive and support a printing device. The anvil has bottom slotsA 51 to receive springs 52 which project beyond the ends of' the anvil and engage the lower flanges 53 of retainers 54 which are provided with upper flanges 55 to overlap the ends of the printing devices. These retainers are slotted to receive screws 56 whereby the retainers are movable under the influence of the springs 52 on the anvil. YWith the slide extended as shown in broken lines on the leftof the machine lli" ig. 3 a printing device is mounted on the anvil and the slide is pushed laterally to the right into the full line position Fig. 3. Then the carriage is operated through printing position and return and as it returns the dog 29 engages the cam end `57, Fig. 1, of a release lever 58 pivoted at 59 on the main frame and operating a latch 60, Fig. 3, which engages a lug 61 `on the under side of the slide and holds the slide in printing position. A tape 62 is fastened to the right end of the slide, Fig. 3, and to a spring barrel 63 supported on the main frame whereby the slide will be automaticallv moved to open position upon the return movement of the carriage. It is intended that there shall be only one printing device on the anvil during each printing operation and also during the in and When the slide returns to open position as shown in broken lines in Figs. 2 and 3 with one printing device 64 retained on the anvil a fresh printing device 65 will be forced bythe operator onto the anvil and under the used printing device 64, the springs 52 permitting the retainers to move suiiiciently for this purpose, and immediately the operator removes the used printing device 64 whereupon the springs 52 will move the retainers 54 into engagement with the ends of the fresh printing device 65 to retain said device on the anvil during the movement of the slide and the printin yoperation.4 The insertion of a fresh printing device and the removal of the used printing device are accomplished in one movement of the operators hand and by proper manipulation of the fingers and can be accomplished easily and quickly and without `the exercise of special skill. To facilitate insertion of the fresh printing device on the anvil the front of the anvil is beveled at 66, Fig. 9, and recessed at 67, Fig. 7. Springpressed dogs 68 are arranged in slots 69 at the front of the anvil to engage the printing device 65 at 70 for holding the printing device pro erly positioned on the anvil against the bac stop 71. The retaining dogs 68 are angular in shape and engage cross pins 72 in the anvil to limit the upward movement of the anvil under the influence of the springs 73. Printing devices may be employed having spacing flanges 74, Fig. 8, and the anvil is recessed at its ends 'Z5/to accommodate the spacing flanges.

This invention providesa machine of simple construction for printing from a stationary form and changeable forms, the latter being fed manually. Machines of this kind are largely employed for printing addressed letters, the body form of the lettei` being fixed on the bed of the machine and the address forms being changeable for each printing operation. ln practice an address form, 64, will be slid into position on the anvil beneath the flanges of the retainers 54 while the anvil and slide are in open position as shown in broken lines at the left of the machine in Figs. 2 and 3. Then the slide is pushed into printing position as shown in full lines 'n lFigs. 2 and 3. The front sheet in the hold r is lifted free of the baiile 40 and dropped again to slide down into operating lposition between the platen roller and the pressure roller. Then the carriage is pushed forward on its printing stroke the sheet being. fed down on the ribbon and printed asthe platen roller passies thereover.` On the return stroke of the carriage the dog 29 operates lever 58 and releases latch 60, Fig. 3, so that spring barrel 63 and tab 62 may. move the slide rto open position for changing the address printing form. Also 'the dog 29 operatesthe ribbon feed lever 32 and pawl 34, Fig. "1. Then a fresh address printing device 65 is inserted in position beneath the used address printing device 64, Figs. 8, 9, and used address printing device 64 is withdrawn. The dogs 68 hold the lower fresh address printing device against displacement on the anvil while the upper used address printing device is being withdrawn. The slide is then loaded for the next printing operation and Iis manually pushed into pintingposition as heretofore described. Meantime the printed sheet has been removed from printing position andthe operations heretofore described are repeated in the next printing operation. The opera-- tions with respect to the address printing device may be performed by the operator with his left hand and the operations with respect to the sheet and the carriage may be performed by the operator with his right hand. `These operations are balanced so that the complete operation of fthe machine may K be easily and quickly performed at considerable speed.

' yv hen the handle 25-is gripped and the carriage is moved in the manner above deprinting operation the handle 25 is released andjn this releasing it is moved sufficiently i roller and said printing bed.

to cause elevation 'of the platen and thus the sheet is free and it may then be removed from moved back into initial position.

l have shown the invention in aselected embodiment which operates satisfactorily in the manner and for the purpose intended but changes in the form, construction and ar-' rangement of parts may be made lto adapt the invention to different conditions and for other purposes and I reserve the right to make all such changes as fall within the scope of the followingclaims:
