SPECIFICATION forming part of Letters Patent No. 770,446, dated September 20, 1904. Application filed July 25, 1903. Serial No. 167,001. (No inodel.)
T 0 (ZZZ whom it may concern.-
Be it known that I, ARTHUR P. SIMPSON, a citizen of the United States, and a resident of the city and county of Sacramento and State of California, have invented a new and useful Improvementin Adding and Recording Machines, of which the following is a specification.
This invention relates to improvements made in machines or devices that are constructed to print and add figures and to record the sumtotal; and the invention comprises certain novel parts and combination of parts, as hereinafter described, and pointed out in the claims at the end of this specification, reference being had to the accompanying drawings, forming part thereof.
Figure 1 of the drawings is a side elevation of the machine, with the top and sides of the case removed to expose the working parts inside, the view being taken from the left side of the machine. Fig. 2 is a similar elevation taken from the right side of the machine. Fig. 3 is a top plan with the operating-keys removed. Fig. 4 is a longitudinal section on line 4 4, Fig. 3. Fig. 5 is a rear elevation of the keyboard. Fig. 6 is a detail side view of the paper-feeding and platen-operating mechanism, the left frame-plate being removed. Fig. 7 is a top plan of the carrying mechanism. Fig. 8 is a cross-section through Fig. 7. Fig. 9 is a detail of the register-wheels. Fig. 10 is a front view of the machine.
This machine is composed of a setting mechanism composing the finger-keys and parts actuated by them, a registering mechanism, and a printing mechanism,which will be described in the order named.
The frame of the machine is composed of a base D, to which are secured the side frames or plates A and B. To the front of these plates is secured the curved front plate C, and just below plate C and between the frameplates is secured the plate 4. (See Fig. 4.)
Loosely slidable in rectangular openings 2 and 99 in the plates C and 4 are a plurality of vertical banks of ten finger-keys each, marked with the numerals 0 to 9, inclusive, beginning with O at the upper key. Any desirable number of rows may be employed,
four rows being here shown. The keys are positioned in vertical planes and radiate from a common center, which is preferably the center of curvature of the plates C and 4. On each key between the plates is a spring 6 to return the key to normal position. Pins 98 prevent the keys from being pushed out too far by their springs 6. Each key is provided with two notches 79 and 5. Outside of the plate C are a series of slotted slide-plates 7 6, normally held down by the springs 78, which plates bear against the key and may lock them in depressed position by engaging in the notches 79. The notch 5 is tapered outwardly and serves to force the locking-plate upward, so that whenever a key is forced in the locking-plate will be forced upward, so that it may be in position to engage in the outer notch 7 9. hen a second key is pushed in, the upward movement of the locking-plate will release the first key. The locking-plates are provided with projections or lugs 81 at their lower ends, whereby they may be moved upward at will by hand, and thus any depressed key be released.
Secured in the frame-plates A and B is a shaft 7, on which are pivoted a series of double sectors 8, having upper segments 9 and lower segments 10. These sectors are yieldably held in their normal positions by the springs 12. The front edges of the sectors are grooved to receive the ends of the keys. The keys are of varying length, depending upon their position and upon the angle of contact with the sector, and are so proportioned that whenever any key is depressed the segment 9 will be turned back a circular distance equal in length to one more tooth than the number indicated on the key depressed. Thus depressing the O key will swing the segment back the space of one tooth, while depressing the 9 key will force the segment back the space of ten teeth.
The registering Medea 222 8222. Journaled in the frame is a shaft 24, to the right end of which is secured the operatinghandle 34, which may be swung forward about one hundred and twenty degrees or from the full to the dotted positions of Fig. 2. On this shaft between the frame-plates are secured a series r of toes 33, one for each sector, and outside of and adjacent to the frame-plates are secured on the shaft the disks 25 and 26, each provided with a semicircular notch 27. Journaled in the frame-plates nearly above the shaft 24 is a shaft 21, on the outer ends of which is secured the register-frame 20, having depending arms 31, carrying rollers '110, that contact with the disks 25 and 26 and normally rest in the notches 27. J ournaled in this register-frame is a slidable shaft 55, upon which are loosely mounted the register-wheels LB 6 g, havmg numerals from 0 to 9 and Which are provided with ten toothed gears- 59. (See Fig. 3.) They are kept in place along the shaft by the guides 106. In the shaft are secured a series of pins 67, normally out'of the path of pins 105 in the wheels 9; but upon sliding the shaft to the left and turning it by the knob 58 the pins 67 will engage the pins 105, so that the .register wheels may be turned to Zero. The shaft is held in place by the spring 108, Fig. 1. Secured to the gears 59 arecams 68, the Office of which will be explained later. Each gear 59 ex cepting the one farthest to the left is located over a segment 9, so thatwhen the handle 3& is moved forward and the frame 20 permitted to drop the resetting of the sectors will turn the wheels g. (See Fig. 4.) As the rear teeth of sectors 9 are cut off the gears 59 will be turned the number of teeth indicated by the key depressed in that particular row and not one more tooth, because of the extra distance the sector is, moved. The transmission of the tens is effected asfollows: On the shaft 62, mounted in the frame 20. are slidably mounted a series of collars 61, having fingers 60 and grooves 66. (See Fig. 3.) On the shaft near one end is secured the segment 63, which meshes with the segment 64, secured to frame A in such amanner that when the gears 59 mesh with the segments 9 the fingers 60 will be inclined downward; but when the frame is elevated, as in Fig. 1, shaft 62 will be turned and the fingers will be inclined upward. (See Fig. 2.) hen the frame 20 is lowered, a plurality of collars 61 will contact with the end of springs 12 1, which are secured to a cross-piece between the frames A and B. When a collar is moved to the left, as will be hereinafter explained, a spring will engage in the groove 66 and prevent the collar from slipping back.
Pivoted to the rear cross-bar 107 of the frame 20 for horizontal and vertical movement are.
the levers 65, which rest on the earns 68 in the path of the pins 57 on the gears 59. v The outer ends of the levers lie in the grooves 66 of the collars 61. (See Fig. 7.) Projecting The operation of carrying is as follows: The fingers 60 are normally between the gears 59 and wheels g, and swinging them up or down has no effect on the registers. henever the 0 passes on the units-wheel 9, its pin 57 moves the end of the lever and the finger 60, controlled by it, to the left in the plane of the tens-gear 59. If-the tens-gear were at 9, its cam would have lifted the end of its lever 65 into the path of the finger 73, controlled by the unitslever 65, and thus the tens-lever would also be moved and the finger 60 on the collar controlled by the tens-lever moved into the plane of the hundreds-wheel. Upon the lifting of the frame20 the fingers 60 thus positioned would each turn their gear one tooth. The same'inovements will occur with am of the other wheels Gr. Near the end of their upward stroke these collars 61'are moved to the right by the pins 71 engaging the cam-faces on the collars.
The printing mechanism.-Secured in the side frames A and Bare three rods 51 100 100, upon which is hung a printing-frame composed of two side plates 101, positioned by sleeves. (See Fig. 1.) Between them are a series of gears 14:, loosely journaled on the shaft 102, which mesh with the segments 10 of the sectors. Engaging these gears are pinions15, secured to the printing-wheels b, all loose on the shaft 17, carried by the printingframe. The printing-wheels have ten projecting type for the numerals 0 to 9 and one blank space. Upon the swinging of the sectors the corresponding printing-Wheels will be moved the requisite distance to present the type of the numeral of the key depressed. hen no key is depressed in any vertical row, no character will be printed on the paper strip. The platen F is carried by two arms 18,'pivoted on the shaft 35. The width of the platen and the printing-frame is less than the width of the register, and the segments 10 of the outside sectors are therefore ofiset, as shown in Fig. 3. On the left end of the shaft 35 is secured the lever 36, thelower end of which is provided with a pin 94:, that passes through a slot in the frame B and engages with the left arm 18 of the platen to swing the same against the printing-wheel. (See Fig. 6.) Pivoted on the pin 39 on the disk 26 is the spring-pressed dog 38, that engages the upper end of the lever 36 during the forward movement of the operating-handle, and thus turns the lever and swings the platen upward. The dog will swing out of the way of the lever on-the return stroke of the disk and handle.
The paper is fed forward by two rolls (Z and e. (SeeFig. a.) The roll e runs freely on a shaft carried inthe rear end of the platen. The roll (Z is fixed to a shaft journaled in the main fraine, and on its left end is secured a ratchet wheel 92. (See Fig. 1.) Loose on the outer end of the shaft isa gear 90, which meshes with the segment 10, journaled on the shaft .24. The arm 91, secured to the gear 90, carries the pawl 93, which turns the ratchetwheel 92. A pin 42 in the end of the arm 44, also journaled on the shaft 24:, may be positioned in any one of the holes 46 as may be desired, and this pin, together with the stationary pin I1, causes the segment 40 to turn the gear to feed the paper a distance depending on the hole &6 selected. It will be noticed-that the angular distance between the pawl 38'and the end of the lever 36 is less than between the pin 42 and the edge of the segment 40, so that the platen will act before the paper is fed.
Supported by the printing-frame on trunnions 87 is a plate carrying an ink-pad 86, which is moistened by the ink in the reservoir 88, having an outlet and a top 89, provided with air-inlet 96. (See Fig. 4c.) The inkingroller 50, carried on a rod secured in the lower ends of links 52, secured to the shaft 51, iscaused to swing by the arm 54:, secured to the right end of shaft 51. The end of this arm 54L rests on the pin 104 and normally holds the roller in the position shown in Fig. 4; but when the operating-handle has moved forward the lever 5% moves down and is held there by the cam 53, and thereby holds the roller 50 over in front of the printing-wheels. By these means only the types presented to the platen will be inked. Just before the operating-handle returns to normal position the lever 54 and the inking-roller will be swung back.
The platen is provided with a top plate or shield 97, that covers all the paper excepting that portion under the opening 109. (Shown inFig. 4:.)
Journaled in the main frame of the machine is a shaft 82, carrying the plate 85, which bears against a lug near the upper end of each slide-plate 76. On the right end of this shaft is a lever 83 in the path of the lug 84 on the disk 25. WVhenever the lever 34 is moved forward, the lug 8 L, contacting with this lever, forces all the slide-plates upward, thus releasing the depressed keys.
The operation of the various mechanisms in their order is as follows: After the desired keys have been depressed and the printingwheels set thereby the handle 34: is brought forward. At the beginning of its stroke the frame 20 is lowered, engaging the gears 59 with the segments 9 and lowering the fingers 60 through the operation of the segments 63 and 6%. At the same time the inking roller is swung forward. Next the pawl 38 engages the lever 36 and swings the platen and paper against the printing-wheels. Next the pin 42 engages the sector A0 to feed the paper, and the lug 8 engages the lever 83 to release the keys, and, lastly, the toes 33 turn back the sectors 8 and advance the register wheels. The parts remain in this position until just at the end of the return movement of the handle,
when the lever 54 will be raised and swing back the inking-roller, the register-frame will be raised to move the gears 59 out of contact with the sectors 8 by the lug 8 f contacting with the rollers 110, and the fingers 60 will be turned upward, thereby transferring the tens. The total sum is shown by and is read from the register-wheels behind the keyboard, from which it is transferred to and recorded on the paper strip by setting the printingwheels as before by selecting the proper keys in the different series according to the required values and numerical order and then printing the sum upon the paper. In this operation of recording the sum it will be noticed that the row of figures showing the result of the addition is necessarily printed over the top instead of at the bottom of the columns.
In the event of an error made during the operation of printing the figures in columns, the correct total can nevertheless be printed if the mistake be discovered before the final operation of setting the printing-wheels to record the total, because such operation is controlled from the keyboard and not directly by the adding mechanism, and a difierent total from that read from the register-wheels may be printed where a mistake in any of the amounts previously set down is found to have been made.
