ADDING AND RECORDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,331, dated January 21, 1896.

V Application filed December 20, 1894. Serial No. 532,482. No model.)

To to whom it may concern:

Be it known that we, LEE S. BURRIDGE and NEWMAN R. MARSHMAN, citizens of the United States, residing at New York city, in the county and State of New York, have in.- vented a certain new and useful Adding and \Vriting Machine, of which the following is a specification.

The object of our invention is to provide a machine that will print and add figures by the operation of a stylus as exemplified in Letters Patent on type-writers granted to us on April 7, 1885, Nos. 314,996 and 315,386, this invention being the outgrowth of that, and an adaptation of it modified to serve the purpose for which it is intended.

Referring to the drawings, Figure l is aplan View. Fig. 2 is a detail side View of the paperca-rriage as seen when looking at the lefthand side of the machine. Fig. 3 is a side elevation as seen when looking at the lefthand side of the machine. Fig. 4 is a detail View of the escapement controlling the adding mechanism. Fig. 5 is a detail plan View of the ratchet and pawl engaging the main wheel. Figs. 15 and 7 are detail views of the escape ment controlling the carriage. Fig. 8 is a front elevation. Fig. .9 is a detail plan View of a portion of the standard 2. Fig. 10 is a detail View of the inking device and type-wheel, looking from the rear. Fig. 11 is a detail plan View of cscapement, partially shown in Fig. 4. Fig. 12 is a detail View, on a much larger scale, of an adding-wheel and tens-carrying mechanism. Figs. 13 and 14 are views of an adding-wheel and its arbor, 850. Fig. 15 is a detail plan View showing the connection between the adding and the paper-carriage frames. Fig. 16 is a side elevation, similar to Fig. 3, but on a larger scale.

1 is the base on which is rigidly secured the standard 2 and posts I}, 4, 5, 6, and 7. On the projections 10 of the standard 2, Figs. 1, 3, and i), is fulcrumed the frame 25 by shoulderscrews. Across the rear part where this frame is fulcrumed is fastened a cross-piece which serves to strengthen the frame, and in the center of this cross-piece is fulcrumed the stylus-arm 20, which projects through the slot 30, Fig. 8, in the front of the frame 25, and at the outer extremity of arm is secured the stylus 27.

The type-wheel 31 and gear-Wheel 32 (see Fig. 16) are secured together and rotated on the screw 33, which enters a projecting lip of the frame 25. (Shown in dotted lines in Fig. 8.) Below the stylus 27 on the arm 26 is secured the rack 34,which meshes in the gear-wheel 32. The frame is held upwardly by the spring 35. Two arms 36 are secured to the standard 2, and rigidly support the letter-plate 37, Figs. 1, S, and 9, which has ten downward tapering slots or sockets, and opposite each a number, beginning with 0 on the left.

15y moving the stylus to the numeral desired the type-wheel will be rotated, bringing the desired numeral 011 the type-wheel opposite the impression-point, and by depressing the stylus it will enter a slot and be locked from any side motion, thereby also locking the typewheel.

The type are inked by the felt roller 40, which is saturated with ink and rotates on a wire which is riveted to the small arm 39, which is fulcrumed to the arm 38, and the spring 41 causes the roller 40 to bear against the type, Fig. 10.

The arm 38, which carries the above-mew tioned arm and roller 40, rotates on the screw 33, which is also the fulcrum. of the type-wheel 31, and the pin 42, which is riveted to arm 38, projects through a slotted guide-piece 11, which is rigidly secured to the post 3.

The normal position of the ink-roller is on the part of the type-wheel 31 over the platen 51, but as the frame 25 is depressed (by depressing the stylus) the roller rides away, owing to the pin 42 projecting into the slotted guide-piece 11, and allows the type to strike the platen 51, Fig. 8, and upon the downward and upward motion will ink the type opposite to the impression-point.

The carriage consists of the frame for carrying the paper and the frame 00 containing the adding wheels and mechanisms. (See Figs. 8 and 15.) These two frames are joined together by a shoulder-screw 44, Fig. 15, and are supported in the front by being fast to the rod 4!), which is longitudinally movable through the opening in the post 4 on the right and bears 011 the wheel 12 (see Fig. 8) fulcrumed 011 the post 3, and at the back the frame is fast to the rod 48, which is longitudinally movable through an opening in the standard 2 on the right and through an opeir ing in the post 5 on the left, Figs. 1 and 15. The two frames 50 and and rods 48 and 49 will therefore travel as one carriage. This carriage is propelled toward the right by the spring 47, (seen best in Fig. 8,) which is coiled on the fulcrum of and bears against the camshaped lever t5, to the free end of which is pinned a pitman 46, which in turn is pinned at its other extremity to the frame 50 of the carriage, Fig. 8. Said carriage is returned to the left by the lever 15, as hereinafter described.

The escapement, which is for the purpose of allowing the carriage to go to the right a tooth at a time, consists of the rack 7 5, (see Figs. 6 and 7,) which is secured to the rear of the frame 60, (see Fig. 1,) and the split springdogs 76, (although made of one piece they act as two,) which are secured to the fiat face of the arm 77, which is pivoted to the lever 78, which in turn is fulcrumed on the screw which supports the left-hand side of the frame 25. (See Fig. 1.)

The dogs 76 are made of one piece of spring metal split in the middle part way, and one half is screwed rigidly to the flat face of arm 77, while the other half has an outward spring the space of a tooth in the rack 75, and which can be regulated by a screw 72.

The lever 78 has a finger key or plate 7 8 at its front extremity above the letter-plate to be used for spacing when no printing or adding is required, and it is also depressed at every depression of the frame 25 by the pin 7 a, which projects from said frame 25 above said lever 78. The spring 7 9 bears the lever up. The dog 7 6 has an outward spring, so that when the lever 78 is depressed the free half will spring out, and when returned to normal this free half will enter the next opening in the rack and be pushed against the flat face of the arm 77, (by a tooth of the rack,) as the spring 47 which propels the carriage is stronger than the spring of the dog.

hen the carriage has gone the required distance to the right and is returned to the left or first position (which operation will be explained farther on) the dog 76 will ride over the teeth in the rackthat is to say, the arm 77 will have an up-and-down motion from the fulcrum, and the spring 7 0 tends to bear this arm down, and consequently the dog into engagement with the rack, Figs. 6 and 7.

The platen 51, which is on the rod a9, is hexagonal in form, as seen in Figs. 2 and 15, and is kept in position by the spring 52 bearing 011 one of its sides or faces, Fig. 8. The rubber rollers 53 and 54: are in rolling contact with each other and serve to feed the paper forward, when rotated, in a manner well understood. They are rotated by means of the ratchet-wheel 55 and arm 56, which has a pawl 57 engaging in the ratchet-wheel. This arm 56 is operated by the connecting rod or link 19, to which it is loosely connected, as will be explained farther on.

The paper is passed between the shield 58 and roller 53, and by turning the rollers it will be guided between them and between the shields 59, which serve to keep the paper secure on the platen, Fig. 2. The paper may be in short lengths; but to avoid the constant entering and for other reasons we have shown a roll of paper 100 on a spool 101, the ends of which are supported in slots in the extremity of two arms 102 which are secured to the base. The roll of paper is stationary; but there is sufficient distance between the roll and frame for the paper to bend as the carriage travels back and forth.

The adding mechanism consists of the adding-wheels 61, which are cut with ten teeth and rotate on the rod 48, which has a keyway cut into it, Figs. 13 and 14, and between each two wheels 61 is placed a thin washer 63, which has a tongue fitting in the keyway in the rod 48, to prevent all the adding-wheels 61 from rotating together, and thereby avoid any frictional action of one wheel on another.

64: are anchoring-pawls which serve to bring and retain their respective wheels 61 in a set position. They are cut at their extremities on two angles which set in the teeth or between two teeth of the wheels 61, as shown in Figs. 3 and 16. The rod 82 serves as a hearing for said pawls, and the springs 65 tend to keep them in engagement with said wheels 61. The triggers 66, arms 67, and pawls 68 are the tens-carrying-over mechanism. On the left side of each wheel 61 (except the last on the left) is a pin 62. (Shown clearly in Fig. 13.) The triggers 66 have the rod fora bearing. The arms 67 have the rod 81 for fulcrum, and at the outer extremity of each arm a pawl 68 is fulcrumed and a spring 69 tends to bear the pawl against the pin 70, Fig. 12. The springs 71 (see Fig. 1) bear the arms 67 up and the lower part of each trigger 66 rests against a jog or step 67 cut in the arm 67 and retains its respective arm down, as shown in Figs. 3, 12 and 16.

The anchoring-pawls 61, triggers 66, and arms 67 all have tubes fastened to them to increase the length of bearing on their supporting-rods and keep them in proper positions. The springs bear against the triggers 66.

The upper part of the triggers 66 is between the adding-wheels 61 in line with the pins 62, so that when a wheel is rotated the pin 62 pushes out the trigger 66, causing the lower part of it to disengage itself from the arm 67, allowing said arm to spring up by the action of the spring 71, and the pawl 68, which is in line with an adding-wheel, will cause that particular wheel to rotate one tooth, as shown in full lines in Fig. 12. The arresting-point of the arm 67 is the rod 83, Figs. 3, 12, and 16.

It will be seen that there are eight addingwheels and anchoring-pawls, but only seven triggers 66 and arms 67. The pin 62 of the first adding-wheel to the right acts on the first trigger and that acts upon the first arm, the pawl of which when let off acts upon the sec ond adding-wheel, and so on, so that the first adding-wheel to the right has no arm in line with it, and the last adding-wheel to the left has no pin and obviously no trigger to act on.

The reading-line of the adding-wheels is the upper central line (see Fig. 1) and the pins 62 are set in aposition to act on the triggers 66 as the wheels are rotated from 9 to 0.

The addingwheels 61 are rotated (except for carrying the tens) by thelarge gear-wheel 90, which is made as light as possible and whose teeth project below the surface of the wheel sufficiently to mesh with the teeth of whichever of the adding-wheels it is operating. For instance, if such a number as 321 is to be printed and added, the stylus is first operated to print the numeral 1, and as the large gear-wheel 90 is at this moment in mesh with the units-adding wheel said units-adding wheel is moved to add one. Now, as the pa per-carriage and the frame carrying the adding-wheels all move as one carriage, the add ing-wheels are moved toward the right the same distance (one notch of the rack as the paper-carriage moves. This movement to the right, of course, brings the next addingwheel (the tens-wheel) into mesh with the gear-wheel 90, so that when the 2 of the number 321 is printed the second or tensadding wheel is rotated (to add the 2) instead of the units-wheel. Of course it is easily seen that as the paper-carriage and the adding-wheels move to the right the proper adding-wheel will be brought into mesh with the operating wheel --that is, when the numeral 2 is printed the adding-wheels again move to the right, thus bringing the hundreds-adding wheel into mesh with the operating gear-wheel 90, so that when the 3 of the number 321 is printed the 3 will be added 011 the hundreds-adding wheel, and so on if a larger number is printed and added. This wheel 90 is loosely journaled on the arbor 92 and has a pawl 98 mounted thereon, (see Fig. 5,) which engages with a ratchet-wheel 97, which is fixed to said arbor 92 and therefore rotates with the arbor as the latter is rotated by the flat coiled spring 91. (See Figs. 3 and 8.) Of course when the arbor 92 and its ratchet-wheel97 are rotated by said spring, the wheel 90 is caused to rotate also, through the medium of the pawl 98, as will be readily understood. hen the arbor is rotated in the opposite direction, the pawl 98 simply slips over the teeth of ratchet-wheel 97 in the usual manner. This wheel 90 is arrested by an L-shaped piece 29, which is rig idly secured to the right of frame 25 and the projecting L of which is between the teeth of the wheel 90, as shown in Figs. 1, 4, and 8. hen the frame 25 is depressed, the wheel 90 is freed from the piece 29 and is free to retate under the influence of the spring 91.

On the arm 26 is fulcrumed the arm 28, which has a finger projecting downward in line with the teeth in the wheel 90, and the spring 36 bears this arm 28 against or parallel with the arm 26. Now when the frame 25 is depressed the finger of the arm 28 will enter between two teeth in the wheel 90, and as soon as the projecting L of piece 29 has passed below the teeth the wheel 90 will-be impelled by the spring 91, carrying the arm 28 with it, the spring on the arm 28 being much lighter than the spring 91, until the arm 28 comes in contact with the set-crew 13 on the post 3, where it will be arrested. (See Fig. 11.) hen the frame 25 is allowed to return to normal, the wheel 90 will have no motion, as the projecting L of piece 29 will enterbetween two teeth before the finger of arm 28 is above the teeth of the wheel. WVhen, however, it is above said teeth, it (arm 28) will be impelled toward the arm 26 by the spring 36. These two arms 26 and 28 each have an opening cut in them (see Fig. 11) to allow movement without contact with the arbor 92.

It must be understood that the teeth of the letter-plate 37 that form the slots or sockets before referred to, except the first on the left, are cut on the same gage as the teeth in the wheel 90, so that when the stylus 27 enters a slot in the letter-plate the finger of arm 28 will enter between two teeth in the wheel.

The different slots in the letter-plate cause the finger of arm 28 to enter the teeth in the wheel the required distance from the setscrew 13. Thus when the stylus enters the first cut on the right-hand end, which is the 9, the wheel will rotate nine teeth before the arm 28 comes in contact with the set-screw13. When a O is to be printed the wheel 90 does not rotate at all, as the arm 28, instead of going centrally between two teeth, willbe close to the one on the right-hand side and up against the set-screw 13, thereby preventing the wheel 90 from rotating. It will be noticed that the first slot in the letter-plate on the lefthand end is not equidistant with the others for that purpose.

The operating-arm 15 is secured on the shaft 16, which is supported by the posts 6 and 7. lVhen this arm is drawn down by the handle it causes the fiat coiled spring 91 to be wound up, whatever amount it may have run out, through the agency of a chain 93, which connects the operating-arm 15 to a drum 94 on the arbor 96, thus causing the latter to rotate, consequently rotating the miter-wheels 95 as the drum and the miter-wheels are fast to their respective arbors 96 and 92. The

drawing down of the arm 15 also causes the carriage to be returned to the left-hand side of the machine, as said arm 15 bears against a cam-shaped lever 45, which is connected to the carriage by the pitman 46,11ereinbefore mentioned. (See Fig. 8.) It will also cause the paper to be advanced for a new line through the agency of the arm 18, which is secured to the shaft 16 and is connected with the operating-arm 56 by the connecting-link 10. (See Figs. 2 and 16.) It will also cause the arms 67 to be reset or such of the arms as have been let off by means of the arm 20 (which is pinned on the shaft 16) bearing against the arm 21, which is loose on the same shaft and which has an inwardly-projecting arm or finger 23, which lies over all the arms 67. (See Figs-1, 3, 12, and 10.)

A spring 22 bears the arm 21 up against the pin 24: on the post 5 to keep the arm or finger 23 normally above the arms. (See Fig. 8.) The arm 15 is normally held upright by means of a spring 17 on the shaft 16. (See Fig. 1.)

The operation consists in moving the stylus opposite to the desired numeral on the letter-plate and depressing it, which will cause that numeral to be printed on the platen 51, and the wheel 90 (and whatever wheel (31 it is in mesh with) to rotate that particular number of teeth. lVhen the hand and stylus return, the carriage will take one step to the right, owing to the movement of the spring-clogs 76 with rack 75, and the next depression of stylus will cause a numeral of a higher numerical order to be printed and added.

WVhen the desired number has been printed the arm 15 is drawn down, which will cause the carriage to be returned to. the startingpoint, the spring 91 to be rewound, the paper to be advanced to a new line, and the arms 67 to be reset, it let off during the rotation of the adding-wheels 61.
