ADDING AND RECORDING MACHINE.

Patented Dec. 28, 1915.

Application filed April 29, 1907. Serial No. 370,324.-

To all whom it may concern:

, Be it known that I, SAMUEL G. Dorman,

a citizen of the United States, resid ng1 at a Poplar Blufi', Miss uri, have invente I16\V:1Ild useful Adding and Recording Machine, of which the following is a specification. This invention relates'to adding and recording machines, and it consists of the novel construction, combination and arrangement of parts hereinaftershown, de-

scribed' and claimed.

This invention relates particularly to that class of adding and recording machines which utilize two or more type-carriers which are operable side by side for recording purposes, and in which two ornnore characters can Heretofore these'machines have been constructed' in this manner, mechanism which is operated automatically to add all of the numbers recorded. machines have been provided with mechanism to eliminate or dissipate from the number in the adding mechanism the last number recorded, which operation is desirable in cases of error.

Occasions arise when it is desirable to record columns or lists of numbers, make and record a total of some of the numbers so recorded, and omit others from the total.

These numbers should be recorded in consecutive order irrespective of whether theyare to be added or not.

The object of the present invention is to produce a machine of the type referred to which shall contain mechanism operableor ad ustable to permit subsequent operation of the recording instrumentalities to record numbers without causing the totalizing mechanism to operate to add such numbers.

A particular object of the invention is to produce a machine of the class referred to comprising mechanism operable to record numbers, mechanism operable automatically to'add numbers recorded, and mechanism operable 0r adjustable eifectively to prevent the addition of numbers by the adding mechanism when the recording mechanism is operated to record such numbers.

A further object is to produce a machine of the kind met-ltie'ned which is operable to record lists or columns of numbers, add cer operator,

be recorded at one operation.

and provided with Some tain of said numbers together during the recording operation and omit others of said numbers from and to produce a visible sign or character to indicate such of the recorded numbers as are not included in the total.

Another object is to produce a machine of the character described comprising mechanism operable to record numbers, mechanism operable automatically to add numthe total as desired by the bers recorded, and mechanism operable or adjustable effectively to prevent the addition of numbers by the adding mechanism when the recording mechanism is operated to record such numbers, in combination with mechanism operable to record words and other data in any, desired relation to the recorded numbers.

A specific object is to provide the special mechanism for preventing operation of the totalizing mechanism during operation of the machine to record, in that type of machine shown and described in the application of Hubert Hopkins, for an adding and writing 'machine, filed January 24, 1903, Serial Number 140390, Patent No. 1,039,130; and in that machine shown and described in my former application for an adding and recording machine, filed October 16, 1906, Serial Number 339,230; and in that machine constituting the subject matter of Dorman and Clayton Patent No. 1,053,913

dated February 18, 1913, application for which was'filed February 11, 1907.

In the drawings whichform part of this specification I have illustrated the invention incorporated in .and forming part of that particular machine shown and described in the said Dorman and Clayton Patent No. 1,053,943, though it will be obvious that the invention may readily be incorporated into machines of various other makes.

Other objects and advantages than those specifically named will be made obvious by the following description without particular mention.

Figure 1 is a longitudinal vertical sectional view of a machine, such as that illustrated in the Dorman and Clayton Patent No. 1,053,943, with the special devices for controlling the operation of the totalizing mechanism as required to permit operation of the machine to record numbers and cause or prevent addition thereof as desired. Fig

2 is a specimen of the work performed by this machine, showing one of the numbers in a column, which is omitted or eliminated from the total at the foot of the column, said omitted or f eliminated number being deslocking device whereby the eliminating train is locked to prevent operation thereof after commencement of any recording operation, so that it is impossible to prevent any number that is-being recorded from being added or registered in the totalizing mechanism except in cases when the said eliminating train isoperated or adjusted before the recording instrumentalities start toward recording position. Fig. 6 is a perspective View of the key for the eliminating train and the totals recording key, and

also a locking device operated by each of said keys, whereby, when one of. said keys is operated, the other one of said keys is lockedagainst operation. Fig. 7 is a longitudinal sectional view of the drivers or hammer section of the machine and a portion of the key-board, illustrating. the entire train of mechanism whose operation or adjustment prevents addition of any number or numbers recorded. Fig. 8 is a perspective view of the devices which cause a distinguishing character to be printed opposite from the recorded numbers that are not included in the total. Fig. 9 is a perspective View of the devices whereby the totalizing mechanism is rendered inoperative or idle when the .eliminating mechamsm is operated or adjusted. Fig. 10 is a cross sectional view of the machine just above the key board and the transversely movable pin carriage.

The entire machine is supported upon the base 1, the recording and operating mechanisms being upheld by suitableframes 2. Av platen 3 is supported in a carriage 4 which is arranged to travel laterally on a carriage support or track 5, thereby affording means for moving the platen laterally for word,

letter, and column spacing, and other pur-' poses involved in the operation, of'the most efficient machines of this class. A series of typewriting type-bars 6 are disposed in position to strike the front of the platen to record words and other data, causing inipressions on thepaper through the medium of a ribbon 7 which winds on spools at the sides of the machine. The type-bars are operated by trains of connections connecting them with their respective keys 8 which are arranged in, rows on the key-board at the front of the machine. Suitable mechanism is provided in connection with the platen for rotating the same as required to effect movement of the'paper for line spacing. The construction and arrangement of these various parts and the method oftheir operation are all fully disclosed in the said Dorman. a nd Clayton Patent No. 1,053,943 and also in the British Patent No. 854, of 1901, before mentioned, and, therefore, do not require specific or detailed illustration or description in this specification.

The adding mechanism and the recording instrumentalities thereof are operably located within the same machine with the typewriting mechanism just above briefly described. A number of-type-carriers 9 are operably supported between the frames 2 and on their front ends a series of types 10 are movably supported. There are ten of" set up and permits them to be actuated forwardly until they are stopped in position to record the number. When so positioned the required types are in alinement in front of the platen in position to be driven to record. When the actuating force is removed from the shaft 13 said shaft is drawn back ward and the type-carriers are moved to idle position by springs 15. The carriage 12 is of that type which moves one space cross wise of the machine-at each operation of one of the keys 11, and carries a series of movableparts 11 which are pushed up by the keys to represent numbers. The step by step movement of the carriage may be controlled in'a ny known manner, one way being by use of an escapement. This operation and arrangement of the carriage are de scribed in the Hopkins patent aforesaid, and said parts are used in the machine and known commercially. The specific construction and arrangement of these parts are immaterial in so far as my present invention 18 concerned, and in practice Lhave adapted my invention to the machine in which said parts are used substantial-l as described in the Hopkins patent. X

li i

.set of gear. parts 16 are movable with the type-carriers. A group of totalizing wheels 17 (Fig. 1) are mounted on a shaft 18 which is mounted in oblique slots in arms 19 attached to a rock shaft'20, so that by oscillating said arms forward and backward, the wheels will be raised and lowered; alternately, into. and out of mesh with the gear parts 16. The link 21 is connected to one of the arms 19 and projects forwardly adjacent to a lever 22 which is attached to the end of a rock shaft 23. Said lever-22 has a projection 24 near each end, one being above the upper edge of the link 21 and one extending under the lower edge of said link. Notches 25 are formed in the edges of said link 21, and it is arranged so that when the machine is idle the projection 24 at the upper end of the lever 22 rests within the notch 25 in the upper edge of the link. Rocking of the shaft 23 to swing the upper end of the lever 22 backward causes the link 21 to be pushed backward. This results in swinging the arms 19 backward and draws the wheels 17 downward out of mesh with the gear parts 16. It is arranged that these parts shall operate automatically upon oper ation of the main shaft 13, all of which is fully described and illustrated in the Hop kins Patent No. 1,039,130 referred to. The arrangement is such that the wheels 17 are lowered in this manner at the start of the shaft 13 and before the gear parts 16 start forward when any number is being recorded and are raised into mesh with the gear parts the moment the shaft 13 starts on its return and just before the gear parts start backward. Thus the numbers recorded are introduced into and added within the wheels 17. Operation of the shaft 23 to effect meshing and unmeshing of the wheels 17 and gear parts 16 by elevation and lowering of the wheels is accomplished by a cam 26 attached to the shaft 13 rubbing against a lever 27 on the shaft 23. .The lever 27 is loose on the shaft 23 and has a pin 28 pro jecting between the arms of a bifurcated member 29 which. is rigid with the shaft 23, thereby allowing the lever 27 certain free movement without effecting the shaft. The shaft 23 and the parts carried thereby are drawn and held in proper position when idle by a centering device 30 of known construction.

When the shaft .13 is started to record a number the cam 26 (Fig. 7)'rubs the lower end of the lever 27 and thereby rocks the shaft 23 which, as described, causes the lever 22 thereon to push the link 21 rearward to lower the Wheels 17. The rear edge of the cam 26 is eventually carried beyond the lever 27 and this occurs, as fully described in Patent 1,053,943 aforesaid, just about the time the types are driven to record, which is after the gear parts 16 have stopped. Then when the parts are started on their return-by the springs 15 the cam 26 rocks.

gear parts 16 and causes the number that had been recorded to be added in the wheels. -It is obvious, therefore, that, if the lowerend of the lever 27 be swung forward beyond possible contact with the cam 26 so as to lower the wheels 17 out of mesh with the gear parts 16, and so that the cam on backward movement will not rub against said lever to raise the wheels, said Wheels will remain lowered out of mesh with the gear parts, and the gear parts will return to idle position without causing that number which had been recorded to be introduced or added in the wheels. The mechanism for preventing this articulation of the adding mechanism and recording mechanism to permit independent operation of the recording mechanism is the special'subject-matter" of this invention, but it is to be understood that such subject-matter comprises part of a complete adding and recording machine which is operable to perform the functions of recording and adding numbers. The types are .driven torecord by a series of drivers or hammers 31 which are pivoted on a shaft 32 (Figs. 1 and 7). These hammers are' arranged in a group, usually referred to as the hammer section, and are held in idle position by a series of pawls 33, provided with hooks to engage with similar hooks on the hammers. To each pawl a trip-bar 34 is pivoted, said trip-bars extending rearward from the pawls through a slotted supporting member 35. Springs 36 are connected to said trip-bars in such manner as to draw them rearward to hold the pawls in engagement with the hammers. A

rod 37 limits rearward swing of the pawls when they are disengaged from the hammers. Two arms 38 on the shaft 32 carry a bar 39 extending crosswise under the rear extensions of the hammers and acting to restore the hammers to idle position, as shown in Fig. 7, when the shaft 32 is rocked to raise said bar. Automatic devices, which it is not necessary here to illustrate nor de scribe, act to rock the shaft 32 and lower the bar 39 during forward movement of the type-carriers to record a number, and when the hammers are released from their pawls said hammers are thrown against the types by springs 40, thereby driving the types to .record. Each, of the trip-bars 34 has a tongue or extension 41 extending under the one in the next lower order so that when any one of said'trip-bars is raised it lifts up all others in the lower orders. When idle the rear ends of the trip-bars 34 are below the are in which the bar 39 is carried so that said bar 39 will pass above all of the tripbars except those Whose ends have been raised. Automatic means are utilized to end of the key-stem 42. A spring 48 is conthis function, are automatically reengaged with the pawls 33 by return of the bar 39. Only the hammers necessary to drive type to record the characters in the number being recorded are released" while all others in higher orders are held idle, the

bar 39 passingover the bars 34. The foregoing mechanisms are all mcluded in the machine shown and described in my said joint application and in the Hopkins British Patent Ni). 854, of 1904, and, for such reason, do not 7 require extended illustration or description here, it being sufficient for present purposes to know that the parts act to perform the functions attributed to them. Each number recorded is automatically taken up or added within the wheels 17 and heretofore there has been no provision in this class of machines whereby a number could be recorded and kept out of or eliminated from the total. My invention, as an embodiment in and part of such machines, comprises mechanism to enable the operator to record numbers and keep out or eliminate any'd'esired ones thereof from the total. In addition it consists of means for indicating those numbers which are so eliminated.

Having described the essential features of one type of machine with' which this mechanism is combinable, I will now describe the mechanism for performing the functions outlined. Within the key-board a special key 42 (Figs. 3, 7 and 10) is arranged, said key having a stem which operates through a slot in the key-board plate 43 and through a slot in the base 1. A rock shaft 44 is sup ported in bearings 45 attached to the under side of the base and has an arm 46 extending forwardly into a slot 47 in the lower nected to an arm 49 on said shaft 44 and to the base of the machine, thereby holding the shaft in idle position, and upholding the key 42. A rearwardly extending arm 50 on the shaft 44 is pivoted to the lower end of a link 51 whose upper end is connected to an arm 52 attached to and extending obliquely downward and rearward from a rock-shaft 53 mounted under the hammer section. An arm 54 on said rock I shaft supports a depending link 55 provided with an elongated vertical slot 56. Said link extends alongside of the lever 27 and a pin 57 on said lever extends through the slot 56, (Figs. 7,8 and 9) and permits movement of the lever 27by the cam 26 without disturbing the link 55 or the parts connected therewith. However, if the key 42 be depressed as far as it will go it causes the arm 54 to raise a sufficient distance to swing the lower end of the lever 27- forwardly beyond possible engagement with the cam 26 when it swings forward and backward while recording anumber. This operation of the lever 27 rocks the shaft 23 'and pushes, the link 21 rearward, thereby lowering the wheels 17 out of mesh with the gear parts '16 just the same as when operatedby the cam 26.: By holding'the key'42 downward the cam 26' can swing in both directions without contact with the lever27, thereby permitting the type-carriers vto travel in both-directions and to record a number without operating the total Wheels 17, said type-carriers and the othenparts of the recording mechanism operating freely to perform their functions, the numbers sorecorded being excluded or eliminated from the total of other numbers that may be recorded and added.

The numbers so recorded and eliminated from the total may, for

' purposes of identification, be designated by printing a suitable character opposite therefrom. [A lever 58 (Fig. 7) is suspended in the hammer section and has a vertical arm and a horizontal arm. The vertical-arm extends behind a pin 59 on a lever 60 extending obliquely downward and rearward from the shaft 23, so that when the shaft 23 is rocked by depression of the key 42 the lever 58will be oscillated. A plate 61 whose upper edge is even with the upper edges of-the trip-bars 34 is pivoted at itsfront end to the trip-bar inthe highest order, and its rear end is even with the rear ends of said tripbars. The horizontal arm of the lever 58 is underneath the plate 61 and, when oscillated,

raises the rear end ofnsaid plate into the path of travel of the bar 39, without, however, raising the end of the trip-bar 34. The bar 39 moving forward strikes the end of the plate 61 and releases the pawl 33 in the highest order, thereby permitting the hammer 31 in that order to be thrown by its.

spring 40.

It will be remembered that, as fully'described in my said joint application above identified when any number is recorded all of the type-carriers move forward to present the foremost types thereon, representing 0 at theprinting or recording line. It

is obvious that there is no use for a 0 on "the type-carrier in highest order, and that type may be displaced bya type ofa suitdesired for it is not essential that any par ticuiar or specific character he used. In the present instance in the example illustrated i link 66 is" pivoted to an in Fig. 2 I have machine, the key 42 is lng position. Depression of the key 42 disconnects the total wheels from the gear parts 16 and raises the rear end of the plate 61..

After the type-carriers have stopped side by; side in position to aline the required types the necessary for recording the number, number of hammers are released, as described above, to drive the types to record. The hammer in the highest order will also be released since the plate 61 is pushed forward by the bar 39. The foremost type on that type carrier will thereby be driven to record a character, in this instance on E opposite from the recorded number. Elevation of the plate 61 does not disturb the tripbars 34 in the lower orders since said plate is independently movable. By holding the ke 42 down until the type-carriers return to idle position the number will have been recorded without addition or registration thereof in the totalizer.

Means is provided mcnced an operation to record. A notch 62 is formed in the key stern An ngular locking member 63, (Fig. 5) c nrrising a vertical arm and a horizontal arin, is pivoted to a support 64, the horizontal arm of said member extending, behind the key stem 42 (Fig. 7) in position to engage, when oscillated, in the notch 62 and thereby prevent depression ofthe key 42. The number 63 has an arm on its lower end and a spring 65 ldcated below said arm to actuate the locking member toward the key stem. A

arm 67 on the shaft 13 and is moved backward and forward during operations of they machine to record. The locking member 63 has a projection 68 which extends behind a lug 69 on the link 66 and thereby holds the locking member out of contact with the key stone 42. The moment the,.parts start to record the link 66 is pushed forward and releases the locking member 63 from restraint and permits the spring 65 to engage said locking member in the notch 62. Backward movement of the link 66 moves the locking member out of the notch, so that the key 42 is operable only before commencement of a recording operation. The key 42 is locked during the operation of recording a total. The totals recording key 70 is depressed whenever the total is to be recorded. The total key 70 has connections '70 leading to the link 2-1 whereby said key, when depressed, will lower the forward end of said link away from the upper projection 24, thereby permitting the shaft 23 to be rocked without moving the supports 17 In tlll jYjL:J/ 4% p8-CLITleI'S to print numbers,

the totalizing wheels and mesh with the gear omitted from the total has been set up in the depressed and then the type-carriers are moved toward record- I'sented in said wheels in the usual and well to prevent depression of the key 42 after the machine has com-' will be retained in parts or racks 16 during forward movement of the latter, thereby enabling the operator to print the total reprean'derstood manner.

: A plate 71 (Figs. 3, 6 and 7 is pivoted recording key is depressed the inclined surface 72 thereon rubs against theedge of the lever 71 and binds the other end of said lever against and under the inclined surface 72 on the key 42, thereby binding said key 42 within the slot in the plate 43 in against depression- This also prevents depression of the totals recording key when the key 42 is down, and holds both keys against simultaneous depression. a

' A complete example of work performed by the recording mechanism of the adding department of this machine is illustrated in Fig. 2. A clear condition of the machine having been indicated by. depression of the totals recording key and operation of the shaft 13.

corded and introduced or added in the wheels 17 as recorded, while the fifth number in the example shown is recorded, but is excluded or eliminated from the total by the operation of the key 42. The distinguishing-character E is recorded opposite from the eliminated number to indicate that it is not included in .the total.

Other numbers are then recorded and added in with the number previously recorded and added, and the final numberrecorded at two spaces below the one next above is the correct total of all the numbers above except that one 'wh'ch was omitted or eliminated.

It will be obvious that there'may be many alterations and VitllfitlOIlS in the construction and arrangement of this invention, and it may be used in other embodiments without departing from the spirit and scope of the invention.

I do not restrict myself to the specific construction, arrangement or embodiment shown and desci'ibed'but \Vhat I claim and desire to secure by Letters Patent is: P
