(No modeld To 1071/0711 7373 Z/ chines known as the American arithmome- Be it known that I, EDWIN B. GRAN, a cititer. I do not, however. wish to limit my 50 zen of the United States, residing at the city of invention to the use of the attachment with St. Louis, in the State of Missouri, have insuch class of machines, as it may be used with vented a certain new and useful 'Iype-IVriting other classes of adding-machines.
- Attachment for Adding-Machines, of which Referring first to Fig. 1, 11 is a cross bar the following is such a full, clear, and exact or plate which is supported from the casing 55 description as will enable any one skilled in 10 of an adding-machine in a manner hereinthe art to which it appertains to make and after to be described. Pivoted to this cross 0 use the same, reference being had to the acbar or plate 11 is the printing roll or platen companying drawings, forming part of this 12. This printing roll or platen 12 stands in specification. the position shown in dotted lines in Fig. 4 60 The object of my invention is to provide a when the adding-machineis printing upon the typewriting attachment which can be applied said platen. IVhen the roll 12 is thrown up to an adding-machine in such a manner that into the position shown in full lines in Fig. 1, in billing and similar uses the type-writing the line of writing is brought to the top of machine can be made to operate alternately the roll, so as to be visible.

Journaled in the plates 25 and 26 is a shaft Like marks of reference refer to similar 30. This shaft 30 has rigidly secured to it a parts of the several views of the drawings. bevel gear-wheel 31. Secured to the shaft 30 In the drawings I have shown the attachadjacent to the gear-wheel 31 are two fixed ment as applied to that class of adding-macollars 32 and a loose collar Carried by the loose collar 33 is a short shaft 34. Surrounding this shaft 34 is a hollow shaft or sleeve 35, having secured to its lower end a bevel gear-wheel 36, meshing with the bevel gear-wheel 31, hereinbefore described. Secured to the upper end of the sleeve 35 is an elongated gear-wheel 37. This gear-wheel 37 meshes with a toothed segment 38, pivoted at 39 to a rearward extension 40 of the top plate 16. Carried by the segment 38 is a forwardlyprojecting handle or lever 41. This handle or lever travels over a curved scale 42, which is secured to forward extensions 43 and 44, respectively, of the top plate 16 and corresponds to the keyboard of a key type-writing machine. The lever 41 is preferably provided with a clip 45, as best shown in Fig. 1, so as to maintain the lever in contact with the said scale 42.
Surrounding the shaft 30 is a hub 47, provided with a spline or feather 48, which engages with alongitudinal groove in the said shaft 30, so as to allow the hub to move longitudinally of the shaft, but to be incapable of rotation independently thereof. Carried by the hub 47 is a type-wheel 49, provided with characters corresponding to the characters on the scale 42. Secured to the type-wheel 49 is a star-wheel 50. Surrounding the hub 47 are two end plates 51 and 52, which, together with a connecting top'plate 53, form a .carriage for controlling the movement of the type-wheel 49. Secured to the top plate 53 by means of screws 54, Fig. 4, are two blocks 55, provided with dovetailed openings for receiving the beveled cross-bar 27. The blocks 55 are connected by a front plate 56, preferably formed integral therewith. Carried by the end plate 51 are a pair of ink-rolls 57 for inking the type-wheel 49. Carried by lugs 59 on the end plate 52 is a rock-shaft 60.
This rock-shaft 60 has secured to it a lockingarm 61, having a beveled upper edge adapted to engage with the teeth of the star-wheel 50, and thus retain the printing-wheel in alinement while printing. The rock-shaft 60 also has secured to it a bent arm 62, which passes up through an opening 63 in the top plate 53 and thence down through a second opening 64 in said plate and terminates directly above the rack-bar 18. Pivoted to the front plate 56 is a feed-dog 65, which engages with the teeth of the rack-bar 18 to feed the typewheel along the shaft 30. 66 is a pin carried by the plate 56 for locking the feed-dog when the carriage is in its depressed position. 67 is a pin carried by the dog 65 and adapted to be engaged by a finger-lever 68 to raise the dog out of engagement with the rack when it is desired to move the carriage toward the left. 69 and 7 0 are pins for limiting the movement of the finger-lever 68.
Pivoted to the end plate 25 is a key-bar 71, which passes up through an opening 72, Fig. 5, in the top plate 16. This bar 71 has secured to its upper end a key 73 for use in printing the various characters carried upon the type-wheel 49. Pivoted to this bar 71 is a short key-lever 74, carrying a key 75. This lever 74 is provided with a locking-finger 76, and it is held in its normal position by means of a small coil-spring 77. The opening 7 2 in the frame 16 is of such width as to allow the locking -finger 76 to pass down through it when the key-lever 74 is in its normal position. When, however, the bar 71 is depressed by means of the key 75, this finger 76 will be projected beyond the bar, so as to come in contact with the top plate 16, and thus limit the movement of the bar and prevent the wheel 49 from coming in contact with the platen to print.
In Fig. 8 I have shown one form of adding mechanism with which my type-writing attachment is adapted to cooperate. Inasmuch, however, as the particular form of adding mechanism is immaterial, and I do not claim the same except in combination with my typewriting device, the same will be only briefly described. The cross-bar 11, hereinbefore referred to, is carried by brackets 80, secured to the casing 10 of the adding-machine, and preferably to the base or lower portion thereof. 81 represents the keys of the addingmachine, which are depressed to set-stops 82. These stops in turn limit the movement of a toothed sector 83, which cooperates with adding-wheels 84 to accumulate the sum thereon. At the same time a second toothed sector 85 cooperates with printingwheels 86 to position the same to print upon the printing roller or platen 12. 87 is an inking-ribbon which is interposed between the type-wheels 86 and the platen 12 to enable said type-wheels to print upon the paper carried upon said platen. The type- sectors 83 and 85 also serve to transfer the sum or total back from the addingwheels 84 to the type-wheels 86, so that the said type wheels may cooperate with the platen to print the sum or total as well as the individual numbers.
The operation of my attachment is as follows: In the normal operation of the addingmachine the platen 12 is in the position shown in dotted lines in Fig. 1 and the characters will be printed along the center line of the side of the said roll or platen. In this position the platen 12 does not cooperate with the type-writing mechanism, but is adapted to be acted upon only by the printing device of the adding-machine. When the roll or platen is swung laterally up into the position shown in full lines, this line of printing will be brought into a visible or sight position and directly beneath the type-wheel 49. When in this position,it is evident that the platen 12 is adapted to cooperate only with the type-writing mechanism and cannot be acted upon by the printing mechanism of the adding-machine. The lever or handle 41 is now moved along the IIO mp4s
scale until the edge of the lever indicates the character it is desired to print. The movement of this lever will be communicated, by means of the toothed segment 38, to the elongated gear-wheel 37. This wheel, by means of the bevel gear- wheels 31 and 36, will impart the movement to the shaft 30, which will rotate the type-wheel 19, so as to bring the desired type directly above the roll or platen 12. The finger-key 73 is now forced down. This causes the sliding rack to descend, carrying with it the carriage and printing-wheel. As soon as the end of the bent lever 62 comes in contact with the top of the rack-bar 18 it will force the locking-detent 61 up into the teeth of the star-wheel, thus insuring a perfeet alinement of the type-wheel. At the same time the feed-dog 65 by its engagement with the rack-bar 18 will feed the carriage toward the right one space. hen, however, it is desired to feed the carriage forward one space without printing, the key-bar 71 is depressed by means of the linger-key 75. The spring 77 will allow the bar 74 to swing on its pivot, and thus project the locking-finger 76 to the rear of the bar. This locking-finger will now come in contact with the top plate 16 and limit the movement of the keybar 71, so that the type-wheel will not be brought in contact with the platen, but the carriage will be depressed sufficiently to cause the feeding mechanism to operate to feed the carriage one space to the right.
Having fully described my invention,what
1 claim as new, and desire to secure by Letters Patent of the United States, is-
1. The combination with adding mechanism, of a platen cooperating therewith when in normal position and movable into a second or sight position to display the printing, and a type-writing mechanism cooperating with said platen when in said second or sight position.
