Specification of Letters lPatent.
Patented June 3, 191 3.
Application filed November 25, 1910. Serial No. 594,069.
T all whom it may concern:
Be it known that I, JOHN J. CHAIIN, a
citizen, of the United States, residing at. De-
troit, in the county of \Vayne and State of Michigan, have invented a certain new and useful Improvement in Tabulating Mechanism, of which the following is a specification.
The principal object of the present in mention is to provide improved means for controlling the movements of a laterally shi't'table paper carriage in the performance of tabulated work such as the listing of items or amounts in several parallel columns where the successive items to be recorded may not follow each other in the order of columns from left to right. In my prior a plication filed June 9th, 1910, Serial umber 566,022, I have disclosed tabulating mechanism for adding machines which rovidcs for shifting of the paper carriage rom any columnar position to any other by continuous action, that is to say without the necessity of stepping the carriage from column to column where one or more columns may intervene between the one from which the carriage is to be moved and the one to which it is desired to move it. In that prior construction movement of the carriage from' an advanced columnar osition to a precedent columnar position involves a return of the carriage to the limit of its movementto the right and the reverse movement thereof to the new position. By the present invention I provide for direct movement of the carriage from an advanced columnar position to a precedent columnar position, that is to say movement in the one direction obviating the reversal of movement above referred to.
The leading characteristics of the present i invention are those above outlined, though there are some minor improvements not here touched upon but which will be pointed out in connection with the detailed description to follow. of the preferred form of embodiment of the present invention which is fully illustrated in the accompanying drawings which form part of this specification.
Of said drawings Figure 1 re resents in left side elevation an adding mac inc of the well known Burroughs type equipped with mechanism for carrying out the present invention, the inclosing casing of the machine proper being omitted, as also part of the left hand frame upright. (The condition here portrayed is that which obtains when the carriage is in its left-most or final columnar position, in the present instance the last of six columnar positions) Fig. 2 is a similar view on a larger scale of part only of machine but embracing most of the mechanism for carrying out the present invention. the condition as to columnar position of the carriage being the same as in Fig. 1; Fig. 3 is a cross sectional detail taken on line 3-3 of Fig. 2; Fig. 4 is :1 section taken on line 4 4 of Fig. 3; Fig. a rear elevation of that portion of the machine illustrated in Fig. 2 with a certain gear casing cover omit-- ted: Fig. 6 is a horizontal section on the line fi-6 of Fig. 5; Figs. 7 and 8 are views similar to Fig. 2, though not including quite so much of the machine and further difi'ering therefrom in illustrating changed relativc positions of parts, Fig. 7 showing the 6th column tabulator key depressed and Fig. 8 showing the first column tabulator key depressed; Fig. 9 is a detail sectional view taken on the line 9-9 of Fig. 8; Fig. 10 is a detail sectional view taken on the line 10 40 of Fig. 8.
While as above indicated the invention is here detailed as adapted to the well-known Burroughs adding and listing machine, itis of course to be understood that this invention is not necessarily confined to such adaptation but may be carried out as adapted to other types of adding and listing machines and in some respects is not at all dependent upon the presence of any adding mechanism. In view of the fact that the Burroughs machine is in extensive use and its basic principles of operation well known, both in this connection and as portrayed in prior patents, (e. 9., Nos-504.963 and 505,07 8 issued September 12th, 1893; 595,864 issued December 21, 1897; 615.895 issued December 13th, 1898), it will be wholly unnecessary to describe the machine proper in any detail, though certain familiar elements thereof will be pointed out as more intimately concerned in the carrying out of the present invention.
A roller platen 17 of the usual kind is mounted as usual in a rocking frame or cradle 2, supported on a laterally shiftable carriage 2 which runs'upon a fixed bracket 3 secured to the framework of the machine proper. Segmental series of type plates 618 are carried as usual upon the rear ends of levers G10 and adapted to be variously positioned under control of the usual amount keys 291 for the purpose of setting up items to be printed on paper overlying the said roller platen through the operation of im pression making devices such, for example, as those shown in aforesaid Patent No. 505,078.
On the back of the carriage 2 there are pivotally mounted two dogs 20 and 21 having confronting end surfaces or edges slightly curved and adapted to serve as stops in fixing the columnar position of the carriage (see Fig. 5). A spring 23 connecting the dogs tends to hold them in effective position against limit studs or pins 22. Journaled in end pieces 12 of the carriage is a rock rod or shaft 11 upon which are secured stop fingers 15 to coi'iperate with said dogs in determining the columnar posit-ion of the carriage. The formation at the outer or acting end of each such stop finger is such as to cooperate cti'ectively with the confronting end surfaces or edges of the dogs as illustrated in Fig. :7. such portion of the finger being tapered or wedge-shaped so that the engagement of the dogs therewith will insure an exact and stable positioning of the carriage. The rock rod 11 is grooved longitudinally as shown in Figs. .7 and 8 throughout a considerable portion of its circumference, and the hubs or bosses of the fingers 15 carry set screws 16 to enter the grooves respectively. It will be obvious that the stop fingers may thus be variously set lengthwise the rod according to the column spacing required by the particular work in hand. it will be noted that these stop lingers are stepped circumferentially of the rod, from which it will be obvious that rotary adjustment of the rod will provide for one or another of the stop fingers cooperating with the dogs to determine the columnar position of the carriage.
Control of the stop rod 11 is had through the medium of a slide bar B slotted to embrace roller mpii uuctl screw studs on the frame of machin and formed with a rack 13 at its rear end which rack meshes with a gear wliwel it secured to said rod. This slide bar f ra with a series of upstanding caai a ction; I with intervening notches or sm and the rear edges of these projections arc inclined at increasing angles from the rcarmost projection to the foremost, and the trout edges are similarly inclined. the angularit'y increasing from the front or foremost projection to the rearmost one. Along the left of the keyboard there extends from front to rear a series of tabulator keys A (Fig. 1) which surmount stems A sliding through the familiar keyboard plates 212 and 213 and also sliding through a special plate 10 secured to a lower portion of the machine frame. The lower extremities of the key stems are normally just under this plate 10 and rollers 7 on these lower extremities of the key stems are normally in contact with said plate and above the horizontal plane of the 'apexes of the cam projections Z), the latter corresponding in numher with the tabulator keys, of which there are six in the present instance; and it will be understood that through co-action between these rollers 7 and the cam projections the bar B will be shifted more or less in one direction or the other to turn the rock rod 11 and bring one or another of the stop fingers 15 into effective position.
It has been before stated that the condition illustrated in Fig. 1 is that which obtains when the paper carriage is in its farthest position to the left, which in the machine here shown is the sixth columnar position, and it will be noted by reference to Fig. 1 that the roller on the warmest tabulator key A stan ds directly over the notch or socket just back of the rearmost cam projection 1). Under these conditions the other rollers stand above the front inclines respectively of the cam projections so that-the bar B will be moved rearwardly varying distances by depression of one or another of the five remaining tabulator keys. The opposite condition, that is to say the condition which obtains when the carriage is in the first columnar position, is illustrated in Fig. 8, Where it will be seen that the roller on tabulator key number 1 has acted upon the forward incline of the first cam projection b and the rollers on the other keys stand over the rear inclines of the cam projections respectively. It will be obvious that by the double dog'c'onstruction already described provision is made for stopping of the carriage under movement in either direction. it being understood that each dog is so formed on its under edge or so disposed angularly that as the carriage approaches a columnar position, whether moving in one direction or the other, the under edge of one dog will wipe over the end of the positioned stop finger and then the end edge of the other dog will bring up against one side of the finger, the first mentioned dog springing down over the other side of the finger so that the latter will be held between the twodogs as illustrated in Fig. 5.
What has been described so far provides merely for selection and positioning of the proper stop finger. The same keys which accomplish this control motor .connections by which the carriage is moved from one columnar position to another. The motor is designated by the numeral 4 and is an electric' motor whose armature shaft is rotatively engaged with a worm 5 meshing with a worm wheel 6, the latter in-turn engaging a worm 44 on a shaft 46 (Fig. 2?, said shaft carrying at its rear end a beve pinion 47. At the back of the machine there is secured a transmission gear casing D and in this casing there is ournaled a shaft 63 to which is secured a veled gear wheel 48 meshing with said bevel pinion 45 so that when the current is on this shaft is continuously rotated. On this shaft there are mounted a pair of cone clutches, the female members 50 and 51 of which are loose and have compounded with them bevel pinions 66 and 67, with both of which there meshes a bevel pinion 55 secured to the lower end of a vertical shaft 56s This shaft at its upper end has secured to it a gear pinion 57 in mesh with a rack 58 on the carriage. It will be obvious that the carria e will be moved one way or the other accor mg to which of the clutches is closed. The male members of the clutches are desiglisted 50 and 51 and they have sleeves or hubs slidable upon the shaft but in rotative engagement therewith, being interlocked with collar pinned to the shaft. Bell crank levers 59 and 60 are pivoted in the casing D and have forked depending arms engaging grooves in the clutch members 50 and. 5-1 respectively. The horizontally extending arms of these bell cranks are oilset with respect to each other and coupled respectively to rods 72 and 7 3'. The latter extend through a rocker plate 74 and have heads above said plate so as to be lifted there to close one clutch or theother accor ing to the direction of movement of the rocker plate. The latter is unified with a lever whose upwardly extending arm 81 has a pin 8-1 occupying a longitudinal slot in the rear end of a slide bar C extending along the; slide bar B and under the tabulatcr keys. This slide bar C has a series of upstanding V-shaped cam projections c of corresponding dimensions and equally spaced apart, and the key-stems carry rollers 8 adapted to act upon the cam projections 0 respectively and move the bar C one way or the other and rock the plate 74 in the proper direction for closing the appropriate clutch.
In my prior application above mentioned a bar similar to that designated B in the present case is shown and also a clutch closmg bar alongside of it, but in that prior construction this clutch closing bar was arranged to move only in one direction to close i one of the two clutches employed, the other clutch being closed through connections op erated upon by the carriage itself upon arrival thereof at the extreme left-hand position. It will..;be remembered that in said prior construction when the carriage was to move from an advanced to a precedent columnar position it was required to move first to the extreme left-hand position and then return to the desired columnar position. Movement of the carriage from an advanced to a recedent columnar position directly, e. without such reversal of movement, calls for control of both clutches by the bar C, and as the direction of movement of the latter must accord with the direction of movement of bar B, said bar C is in. the resent instance put under control of the bar ll. This -is accomplished as follows: The bar B has a rack b which is in mesh with a gear wheel 36 secured on a sleeve 37 journaled on a screwstud 41 fastened in the machine frame. A friction disk 38 is also secured to said sleeve (see Fig. 3) and there is loosely mounted upon the sleeve a gear wheel 40 considerably larger than the gear wheel 36. A cupped spring disk 39 is fastened to a nut 39 which engages screw threads on the sleeve 37 and holds the said disk 39 in frictional engagement with the inner side of the gear wheel 40, the adjustment being preserved by a lock nut 42 a! plied to the screw threaded portion 0! the sleeve 37. The disk 39 is slit radially to pro vide the desired resilience and flexibility.
The gear 40 meshes with a rack c on the slide bar C and it will be clear that through this gearing a connection is established hetwcen the two slide bars whereby the movement of the slide bar B will be transmitted to the slide bar C. Frictional connection between the two gear wheels is necessary because of the variable movement of th.s-lide j bar B and the necessity for its transmitting movement to the bar C equal in extent to the slot 83 when thesaid bar B partakes of the least degree of movement'under actua- 1 tion by a tabulator key, and of course the extent of movement of the bar C must be the same when the bar B is moved to a greater extent. Furthermore, when the movement of the bar B is in the same direction that it was last previously moved and therefore the proper end of the slot. 83 is already elwaged with the stud 81, no movement should be transmitted to the bar C notwithstanding the gear 36 will be turned R will be understood that the shifting of the bar C by the bar B does not afi'ect the clutch closing lever 81 butis merely preparatory to a throw of said lever in the right direction by further movement of the bar C as produced by action of a tabulator key thereon. This occurs after the key has completed'the movement of the bar B and then acts upon one of the'cam projections c. The reason for employing gears of different sizes is that the movement of the bar C must be multiplied over that of the bar in order to shift the cam projections c will-act on the rear sides of from a position where the rollers 8 will act upon the front inclined sides of the cam pro- Jections c to a position Where the said rollers ject-ions, and vice Versa, notwithstanding the movement of the bar B is very slight, e. 9., when the carriage is moved from one columnar position to the next. Thus, referring to Fig. 2, if the next to the rear tabulator key should minimum movement to the bar B by the action of its roller 7 upon the front incline of the cam projection b, the angularity of which is such that the same degree of movement imparted to the bar C would not carry the point of the cam projection of the bar C to the rear of the vertical central line of the roller 8, Whereas the multiplication of movement provided for by the differential gears insures an extent-of movement of the bar O which will establish the necessary relation between said cam projection of the bar and the roller 8.
It will be understood that the proper relation between the slot 83 and the stud'81 having been established, the shifting of the bar C by the tabulator key roller rocks the lever 81 and thereby closes one clutch or the other through the tilting of the rocker plate 74. Of course with the rise of the tabulator key the lever should assume its neutral position, and in order to effect this the lever has a depending arm 76 with a stud 84 lying between jaws 79 mounted on a common pivot and connected by a spring 7 9.
It will now be seen that the above described construction provides for the ac- .ing the front end of said slot into complishment of the object first stated, towit, that of causing the carriage to move automatically from any columnar position to any other. Thus if the carriage is in the sixth columnar position illustrated in Figs. 1 and 2 and it is desired to moveit tothe first columnar position, tabulator key numher 1 is depressed and will act upon front inclined side of the cam projection 19 with the effect illustrated in Fig. 8, where the key is shown fully depressed, having shifted the bar B and thereby disengaged the sixth stop finger 15 from the carriage dogs 20 and 21 and brought the first stop finger into line with said dogs, and the movement of the bar B has transmitted movement in the same direction to the bar C through the diflerential gearing, thereby moving the rear end of the slot 83 away from the stud 81 and bringengagement with said stud. Following this actuation of the bar B and its actuation of the bar C, the latter is further actuated by the key so as to rock the lever 81 and close the right-hand clutch (Fig. 5), thereby starting the carriage to the right, the carriage continuing to so mo've until the dog 20 strikes said cam pro-,
be depressed it would impart thethe bar C to the position the positioned stop finger. It is obvious that the shifting of the carriage from any other advanced columnar position to any other precedent columnar position can be accomplished in the same manner by operating the appropriate tabulator key, and it will be equally obvious that shifts of the carriage from any precedent columnar position to any advanced columnar position can be accomplished in like manner (see Fig. 7) through the medium of the other clutch, towit, the left-hand one as the parts are seen in Fig. 5.
It will be understood that in either case the movement of the bar C derived from the bar B stops when the end of the slot 83 comes against the stud 81, the spring 79 being superior in its resistance to the friction between the gears, Then when he key is forced farther down, the direct action on the bar C overcomes the said spring 79*. Upon release of the key, the spring restores from which it was last moved, but the bar B is unaffected, being locked in position, as will presently be described, so that the gears slip again.
In order to lock the bar B in any position" to which it is brought by depression of a tabulator key, the following construction is employed: On a raised portion of this bar there are formed a series of square notches 95 (Figs. 1, 2 and 7) and there is pivoted to a frame bracket 31 a locking pawl or dog 25 having an acting end adapted to engage any one of saidnotehes for locking the bar. An upstanding armof said pawl 25 is normally 100 engagedby trip pawl 28, the engagement being enforced by a spring 27 connecting this trip pawl with the locking pawl and so serving also to enforce engagement between the locking pawl and notch. The trip pawi is pivoted to the rear end of a bar 32 extending alongside the ke: stems and guided in a s of the bracket 31 and a slot of a siini. .n .1' bracket 33, to which latter bracket the i' is connected by spring 35 holding it n mally to the left as the parts are seen in in figures above referred to. The bar 32 r: ries a series of studs 34 normally occup cam notches 36* in the sides of the key 'When a key is depressed the upper s its cam notch acting upon a'stud of t 32 forces the latter to the right, there t Y ing the trip pawl 28 to rock the locking pawl and disengage it from the. bar B so that by the time the roller 7 reaches the cam projection 11 of bar B the latter will be unlocked and subject to movement in the manner hereinbefore described. There are formed upon the key stems at points above the" aforesaid cam notches cam projections 125 6 to act upon the sti1ds34. Thus a key having been depressed and the bar 32 shifted to the right in the manner described, further depression of the key after its roller 7 has passed downwardly beyond the incline of the cam projection b will result in the cam projection 36* acting u on the stud of the ar 32 and moving the atter farther to the right, causing a depending arm of the trip awl to encounter an abutment screw 30 set in the bracket 31, with the eifect illustrated in Fig. 7, to-wit, thatof rocking the trip pawl out of engagement with the locking pawl and permitting the latter to reengage the bar B. Of course when the key is released and rises the parts resume their normal relations, the bar 32 being moved back to the left by its sprin 35 and the trip pawl becoming reengaged with the locking pawl.
