Original No. 1,069,152, dated August 5, 1913,

' Serial No.

To all whom it may concern:

Be it known that I, J ASON C. InrrEnHAND, a citizen of the United States, and resident of New York, in the county and State'of New York, have invented certain new an useful Improvements in Printing Mecha: nisms for Adding-Machines, of which the following is a specification.

This invention relates to adding machines and more particularly to the printing or recording mechanism thereof and its novelty consists in the construct-ion and adaptation of the parts as will be more fully hereinafter p ointedout.

In an application for Letters Patent of the United States filed by me on the 24th of February, 1908, Serial No. 7,352, I have explained the subject matter of this applica tion in connection with the accumulating and calculating mechanism used therewith and this application is divided out of the one referred to at the request of the Patent Oflice. f

In order to understand the construction and mode of operation of the printing mechanism hereinafter described, it is necessary to understand the construction and mode of operation of the cooperating mechanism and therefore there is described in this application much which will be found in the prior application, but such repetition is necessary.

- One of the objects of the present invention is to provide an improved form of constructionof the devices by which the. several type carriers, after being positioned according to the keys depressed, are caused to make the impression on the printing surface.

Another object of the invention is'to provide an improved construction of the memhers usually known as tlie rack and type plates.

A further object of the invention is to provide an improved member that will cooperate with the rinti'ng means for the purpose of preventing the type carriers tov be engaged or propelled to print during the operation of the machine after the keys have been depressed,- so that while the accumulating mechanism will'operate in its usual manner, no printing operation will take place. 1'

Another object of the invention is to provide an; improved form ofmeans for shift-1 Specification of Reissued Letters Patent. Reissued J 1y 28, 1914, Serial No. 440,399. Application for reissue filed May 23, 1914.

Fig. 22 is a front elevation of-thesame parts. Fig. '23 is a side elevation of the rear portion of the machine similar toF ig. 2. Fig. 2% shows a portion of the means foroperating the multiple detent.

In the drawings, the parts are shown in Fig. 2 mounted upon and within the framework comprising a base plate 2 and an outer upper casing 3 completely enveloping the machine and suitably apertured to permit of the passage of some of the parts. It is provided with a series of vertically arranged upwardly serve assupports for the key system and with two other similar plates 5 to support other'parts, as hereinafter described. Each of these plates at and 5 are mounted in slots formed in transverse ribs 500 made integral with or secured to theibase of the machine.

. Each rib is longitudinally apertured and when the plates are in position a retaining bolt 501 is passed through such aperture and also through apertures in'tlie plates regis -tering therewith and a nut 502 engaging the end of the bolt holds the plates firmly in position.- Each of these plates at its up- ..per edge is provided with two projections 503 adapted to engage with suitable slots in thekey plates 41 hereinafter referred to. Each plate 4 at its rear end is provided with a transverse guide plate 7 having right angled apertures 8 to permit of the passage of the. stop bars 9 hereinafter mentioned. Each plate- 4 is also provided with a series of recesses 10 to receive the key stems hereinafter referred to. Projecting upwardly through the casing tionalseries in the-usual manner, each provided with a finger iece 12,and with-a depending stem13 a apted to reciprocate in one'of the recesses 10 of the plate 4 immediately beneath it and guided by an aperture in the upper key plate 14 through which it passes and by its recess 10, the bottom of this recess serving to limit its down-,- ward movement; At its bottom, each stem 13 is hinged toonecndof an elbow lever 15. pivoted at 16 to the plate 4, the otherend of which lever is hingedto a horizontal stop. bar 9, the rear end of which passes through the aperture 8 provided for that purpose in the guide plate 7 Each bar9 is reduced in cross section at the rear of a shoulder 17 and a retracting spring 18 is'placed around the end of the bar and between this shoulder 17 and'the transverse guide. plate 7. Each bar is provided on its upper edge with two adjacent notches ,19 and 20, on each side I of a summit 21 common to both. The elbow levers and the stop bars 9 are arranged alternately on opposite sides of the plate 4 common to each series. Each series of keys is providedwith a latch bar 22' vertically suspended in a recessin the plate 4 on two parallel :irms, an upper arm 23 and a lower arm similar but not shown,

pivoted to the plate l. A rearward extension 25 of the arm 23 is hinged to an upwardly projecting release bar 26 pivoted to a release lever 27 hinged at 28 to a suitable bracket 29 projecting from a plate 30 mounted under the upper part of the casing. Thelever 27 has a finger piece 31 with which it has a slotted connection.

Each latch bar 22is provided with projecting studs 32 adapted to engage with the notches 19 and 20 in the stop bars 9 and also with a retracting spring tending to move'it downward. It has a cam surface 34 on' its lower front edge.

Hinged at to each plate 4 is an elbow lever 36. Its upper arm 37 has a notch 38 and it .is also provided with .a roller 39. Its lower arm 40-is provided at its rear end with a tip 41. Hinged at 42, also to the 3 are the keys 11, arranged in denominathe tip 41 and connected by a hub to an upwardly extending arm 45 having a hook 16.

Hinged on the plate l is a latch arm 49 provided with a notch 50 adapted to engage with the notch 38 of the lever 36 and having a slot adapted to engage with a stud 52 projecting laterally from the latch bar 22.

depressed its elbow lever 15 is moved and its stop bar 9 is forced forward against the action of its spring 18 until its notch 20 has become disengaged from its stud 32 on the latch bar 22 and its notch 19 has become en the operator begins pulling the main handle of the machine, as hereinafter described, finds that he should have depressed some other key of the same series. He then depresses such other key and its stop bar 9 is moved. forward and its notch 20 engages its stud 32 on the same latch bar 22. When theisurnmit 21 is reached, the stop bar 9 of the former key, under the influence of its spring 18 is at once retracted to its original position and its notch 19 again engages wlth its stud 32. In other words, if any key in a denominational series has been depressed, depressing any other key in the same series, not only positions the stop bar of the second key in its proper place, but automatically and merely as an incident of said depression, restores the key first'depressed to its original position. If an item has been enumerated by the depression of a number of keys in different series and it is desired to restore the key in which they have been depressed, to their original positions and thus eftace the item, the release lever 27 in any series desired is actuated by depressing. its finger piece 31. This moves downwardly the rod 26 which lifts the arm 23 of the latch bar 22 so that the stud 32 on the latchbar which has engaged the notch 20 of the stop bar 9 of therefrom and the key is restored to its original position. Before any numeral key is depressed the parts are in the position shown in Fig. 3. When the key is depressed, as the engagement of the stud 32 with the summit. 21 of the bar 9 occurs, the latch bar 22 is lifted and this raises the stud pin 52 which moves upwardly and elevates the latch arm 41.9. -As the latch arm is raised its n0tch50 is raised to permit the notch 38 of the arm 37 to slip under it. This permits the elbow lever 36 to swing on itspivot 35 under the influence of a spring 55 secured to the arm 40 for that purpose. Such movement causes the tip 41 to impinge against the lever 43 and oscillates it on its pivot 42 moving the hook 46 out of the path of a projection on the rack and type plate 81,

By this construction the triggers 210 can each turn on the shaft 211 but the entire series of trigwheels 60.

-The adding, carryin totalizing and re setting operations 0 the accumulating serves. as a guide for the upper end of the lifting frame 268.

The purpose of the lifter is to position the ribbon at the point of print each time an item is to be recored and to remove it out of the way at other times. As above mentioned, the lifter is pivoted to the brackets 213 and is raised and lowered by the shaft 101 at each, actuation of the main shaft. The-parts are so arranged that the lifter is raised so as to bring the ribbon to the point of print at the extreme end of the forward stroke of the handle and after the actuators 200 have been moved forwardly to be in position to strike, so that the types are propelled forward at the instant when the ribbon is in position. As the rearward stroke of the handle begins the lifter is lowered and the ribbon is thereafter out of the Way until the main shaft is again actuated.

It has been explained how at each actuation of the main shaft the-universal bar 103 is lifted and the rack and type plates 81, corresponding to the denominations in which no key has been depressed, are raised to bring their 0 types oppositemhe point of print; because the parts are so proportioned that the beak of the hook 16 engages the projection 91 to bringthe 0 type at the other end of the same plate 81 to the proper point. It has not been explained, however,

how the. zeros 'are automatically printedr This willnow be done.

Eaclractuator 200 is provided with an arm 207, as above described, which extends over toward the body of the actuator of next lower order, so that when-an actuator is moved its arm engages with the actuator of next lower order (provided the latter has not been already engaged by its own trigger 210) and bodily moves the latter to retract its energizer and be propelled toward its type when the trigger 210 of the first named actuator-is released; Thus the rack and type plate 81 in each denomination where no key is depressed is automatically moved to bring its 0 type to the point of print and its actuator is automatically energized and propelled forward to print such .type. In a similar manner any-otherv actuator of lower order, the rack and type plate of which has been moved tothe 0 printing point is actuated by the adjacent actuator of higher order, whether such adjacent actuator has been brought to the 0 point or to a point to print an integer.

-The non-printing. key comprises a" key stem .410 haying a finger piece 411 and a notch 412. (see Fig. 24:). It is hinged at its lower extremity to one end ofan elbow 113,

the other end of which is pivoted to alever 414 extending longitudinally of the machine and pivoted to a crank 6 on a cross shaft 415' which is adapted to oscillate a'multiple detent 4:16 mounted between the two brackets 213 (see Figs. 2 and 23). This detent comprises a series of hooks 417 which are so positioned as to engage pins 4-18 rojeeting laterally from the arms 216 of t e triggers' 210 (see Figs. '3 and 4:). It is obvious that when the key 410is depressed the hooks 117' are oscillated into the paths of the pins 418 so as to interceptthe triggers and detain them against movement. When they are so prevented from moving, the type actuators arenot moved or energized and no printing operation cantake place. The function of the printing mechanism is interrupted so long I as the key 410 remains depressed.

.When the key tlOisreleased a spring 119 serves to retract it to its original position.

It is to be noted that in the above described mechanism, the parts are free from complication in construction and mode of operation; their movement 'is direct and positive and usually in straight lines; they can largely be made of standard material and without elaborate finishing processes; their operation requires little power; the key touch is light and the handle action does not induce undue fatigue. There is accom plished in this device everything accomplished in much more complicated machines, and in a more economical Way, and the cost pf its manufacture and use is necessarily ess.
