10 upon which appears line by line the items of all of thebills. 1 y 1 Thus the record-sheet keeps acornplete record, While the tally-strip serves as a separate device for preserving the bare amounts of the 15 items. 1 1 i It is usual to mount upon the typewritercarriage a roll of paper which serves forsuch tally-strip. The type-impressions are usually made upon the tally-strip by use of carbon, 20 and the carbon is usually in the form of another strip, [which pays off from another supply-spool. 11 1 1 'The carbon-strip is, usually imposed npon the tally-strip, and both run through the ma- 2 chine around the platen, between the platen 1 and said Wide sheet. That is, the tally-strip usually runs directly in contact with the pl aten,'and is overlaid by the carbon-strip, and both are overlaidbythe aforesaid record- 3 sheet; and 1a carbon-sheet is interposed between said record-sheet and the main sheet or bill, upon which the'typing is directly inked. 1 1 1 The bill is removed from the machine after 1 an item or set of items istyped thereon, and

a fresh bill is inserted in place of it, Without disturbing any of the remaining sheets.

hen the fresh bill is typed,carbon-copies thereof appear below the previously typed 14 lines upon the record and tally-strip, the

Typewriting machines ,for this class of worlrhaveiusually been supplied individually with diiierent capacities of strip mechanism,

that is, ith capacities for different Widths of strips. NVhere only one strip asto be used, the typewriting machine has been equipped accordingly, and if it were then desired toemploy a different idth of strip, itWas usually necessary to buy a new machine, especially equipped for the ider strip.

Thus according to former practice, it was necessary forever-y branch oflice of a type writer manufacturing concern to carry in stock as many sizes of tally-strip mechanisms as there were idths of tallystrip used and it was necessary for machiniststo install each tallystrip inechanisn'i upon a typcwriting machine before deliveringit to the purchaser.

There has been heretofore devised a telescopic equipment, having extensible spools, etc, this telescoping giving a certain rangeof variation to the equipment, so that by means of a few equipments of different, general ea pacities it became practicable to accommodate many widths of strip, thus reducing the number of sizes of equipments that itfwas necessaryto manufacture and furnish. Ac cording to this telescopingplan, it became practicable to enable a branch office to meet the needs of the customers ithout the njeces sity of carrying more than three dillerent sizes of tally-strip mechanisms in stock,

According to said telescopic plan, eachtally-strip was furnished upon a core of a length commensurate with the width of the strip, and the same was true of each carbonstrip, so that it was not necessary to provide for extending any cores, in adapting the machine for different widths of strip. The can bon-delivery spool and the tally-strip-delivery spool and the temporary winding spool were all carried in due relationship between a pair of mounts or side frames; and provision was made for adjusting these side frames towards and from each other along the platen or carriage of the typewriter, to accommodate different lengths of spools, thereby making it practicable to support any length of spools, carrying any width of strips, by means of-the same side frames.

' The platen frame or carriage carried a pair of tracks having the form of rods, which were mounted at their ends upon the ends of the platen-frame. Along these rods each side frame was slidden independently, to permit the placing of spools between them; Then the side frames were s cured in a manner to prevent them from becoming displaced along these base-rods.

One of the base-rods or slideways aforesaid, upon which the separable frames were adjustably mounted, was caused to rotate by means of a train of mechanism that was driven by the usual line-spacing and carriagereturning lever of the machine, which in this case was an Underwood standard typewriter.

This rotation of the rod was imparted to the aforesaid temporary wlndlng spool, regardless of the position to which the mount may be adjusted along the rod.

In the present improvements the need of telescoping is eliminated and the temporary winding spool is splined to a stub-shaft, which is formed upon an arbor that is mounted upon the left-hand side-head or frame, and is geared to said rotating rod and its line-spacing train, whereby the temporary winding spool, of whatever length, is caused to revolve during the line-spacing operation.

This arbor may have a spline, as for example its stub may be square in cross-section, and the spool-head may have a square hole to fit. Thus it will. be seen that at all adjustments of the frames, in accommodating any width of tally-strip and tally-strip rolls, at any position along the platen, the temporary winding of the tally-strip and its superposed carbon may proceed automatically during the operation of typing the bill line by line, without the lpecessity of telescoping the side-heads toget er.

lVhen a sufiicient portion of the tally-strip has been typed, it is pulled off from the temporary winding spool, and at thistime the portion of paid-off carbon may be wound back upon the carbon-spool; this rewinding being effected by means of a thumb-wheel and arbor which are provided preferably upon the right-hand mount or frame, the arbor having a square shaft to fit in the square hole in the end of the carbon-spool.

For cheapness of manufacture, all spoolheads are made with square holes, and ac cordingly all of the stubs or gudgeons in the mechanism may be square, to fit said holes. Both gudgcons of the idly-revolving tallystrip-delivery spool may be squared, to fit t 10 square holesin ,the heads of said spool. Permanent heads are secured upon the tally-strip and carbon-gudgeons, and the rolls consist of strip-windings upon headless cores, the cores having square bores to correspond with the gudgeons or stub-shafts.

The temporary'rcwinding spool does not need to be provided with spool-heads, as only a few turns of strip are ever wound upon the temporary winding spool, rendering heads unnecessary. This enables the tear-off knife to be placed comparatively close to the core of the rewinding spool.

According to the present improvements, it is only necessary for the branch oflice to carry a single kind of tally-strip mechanism in stock, for all customers. The branch office carries a stock of tear-off knives, all of which are of maximum length. in filling each order, the surplus length of knife is cut off, and the remainder is uscdas a tie-rod between the side-heads, without objectionable projection.

The provision of means for fastening any v commonly-used width of tally-strip and carbon-strip to the wind-up roll is another feature of the present invention. There are provided two short inreaching fingers, one fa."- tened to each stub-shaft of the wind-up roll and spaced a short distance outwardly from the core. These fingers are thus laterally adjustable for use with different widths of strips. Fastening the tally-strip and carbonstrip to the wind-up roll can be easily done by inserting the leading ends of these strips between the wind-up core and the inreaching fingers, and then folding short sections of the strips together back over the iii'igers.

Another advantage is afforded by provision of the inreaching tally-strip-fastening fingers. A typed section of the tally-strip and the overlying section of carbon-strip can be unwound from the wind-up core and the tally-strip held stationary while the carbon strip is'rewound on the carbon-strip core. Furthermore, the tally-strip thereafter can be conveniently manipulated for bringing it to cutting-off position relative to a cutoff knife provided on the tally-strip device.

Other features and advantages will hereinafter appear.

Inan Underwood typewriting machine types 10 strike against a platen 11 on a platenshaft 12, which is journaled. in end plates 13 of a platen-frame 14. For guiding a worksheet, such as a bill 15,around the platen from the rear, a rear paper-table 16 and lower feed-rolls 17 are provided. The parts described hereinbeforle may be of the same constructionas in a standard Underwood typewriting machine. e

For line-spacing the platen as the typing proceeds, a usual. ratchet-wheel 20 is mounted on the platen-shaft 12, and a drive-pawl 21 is mounted on a slide 22 in the platen-frame 14. The slide 22 is pushed rearwardly upon operation of a usual line-space lever 23 and is returned by a retractile spring 24. The slice may have an upwardlyextending lug 25 to which is pivotally fastened the lower end of downwardly-extending arm 26 of a link-member which has a rearwardly-extending arm 27 integrally joined to the arm 26.

For mounting the tally-strip device on the typewriting machine, a bracket-plate 30 is mounted on each end plate 13 by screws 31. Extending between the bracket-plates 30 is a c1'ossrod32 and a cross-shaft 33. For

mounting the rod 32 in the brackets 30, a hole 341-. is made in each bracket adjacent the upper edge'at the rear of the bracket, and a slot- 35 is. cut through the rim around each hole.

To provideibracing meansfor the rod 32 and shaft between the brackets .30, two stiffening plate-members 43 may be mounted on a usual crosswise. platen-frame rod 44: extending between the end plates 13. Each of the platermembers 13 mayhavea forwardly-extending arm 45 carrying. a rotatablymountedlroller 416 which bears against the platen 11.

up rolls for thetally-strip, designated as A,

and the carbon-strip, designated as O, in my tally-strip device, a frame, generallydesig nated as 60, includes right-hand and lefthand side-heads or frame-members 61 and 62, respectively, each of which is slidably mounted on the cross-rod 32 and the cross-shaft 33. To seat the framennembers 61 and62 securely on the cross-rod 32, each mcmberhas a clownwardly and. rearwardly inclined mounting slot 63 cut in it to engage with working fit A hole is provided in each framememberfor slidahly engaging the cross-shaft 33. The frame-member 61 has a rigidly fastened hub 6 1 which "engages around the cross-shaft 33. A collar 65 upon shaft 33 is adjustable .therealong and can be fastened against the hub 64 in any adjusted position of the frame 60 by a set screw 66.

The side-head 62 has fastened'to its left face a hub 67 whielrengages about the shaft 33. Abutting the left face of the hub 67 is a gear-wheel 68 loosely mounted on the shaft 33. Secured to the gear 68 is a hub 70, which may have clutch-teeth 71, as indicated in Fig ure 1. A companion tooth clutch-member 72 for the hub 70 is mounted on the shaft A pin-and-slot means may be provided l ke those disclosed in the co-pending application of Otto Thieme, Serial No. 304,653, filed September 8, 1928, for latching the clutch-member 72 out of engagementwith the clutchmember 71, at will, against the pressure of a spring 7 3, which acts against a knurled thumb-piece 7 4 integrally joined to the clutch-member 72. A collar 7 5 is mounted on the shaft 33 for lateral adjustment therealong by a set-screw 76 and serves as a backing for thespring 7 3, which normally presses the clutch-me1nber 7 2 into engagement with the clutch-member 71. Bythis arran ement,

the gear 68 is operatively connected through the shaft 33 to the line-space lever 23 for stepby-step rotation upon operation of the linespace lever.

Tally-strips and carbon-strips for use with the tally-strips are usually supplied wound on cores to form supply-rolls. According to one way of carrying out the present 1nvention, the tally-strip and carbon-strip feedrolls are wound on inexpensive paper-cores 80, which may have substantially square axial bores 81. A core ordinarily adds very little to the cost of a roll of tally-strip or carbon-strip, and the core may be discarded when empty or bare. As will appear hereinafter, the empty core 80 from whi h the tallystrip A has been unwound can be used as a core for a wind-up roll on which both the tally-strip and the carbon-strip are wound as the work proceeds.

For mounting a tally-strip feed-roll, des ignated as 82, the core 80 of the feed-roll is slipped over the rod 32, and each end 01" the core engages on a short inreaching stub-shaft, generally designated as 84-, which may be sub stantially square in cross-section for fitting snugly in the square bore 81. Each stubshaft has an axial bore slightly larger in C11- ameter than the rod 32, around which it engages a spool-head flange-member 85 and an integral hub-portion S6.

To provide a brake-means for the t-ally strip feed-roll 82 for preventing the tallystrip from being unwound accidentally or too fast, a radial hole 87 is drilled iireach hubportion 86 and is tapped to receive a set-screw 88. The extreme bottom portion of the hole at each hub'portion is slightly reduced in diameter to form, in a well known way, a kind of retaining flange where by the steel ball 89, which fits loosely in the hole, can project slightly beyond the perimeter of the axial bore of the stubshaft when the ball is pressed by a coil sp ing disposed between the ball and the screw 83.

The pressure of the spring 90 forces the side of the wall of the stub-shaft axial bore opposite the ball against the rod 32, and the friction caused thereby acts as a brake to keep the feed-roll 82 from unwinding accidentally or any faster than the tally 'ip is wound up. Provision of the friction-retarding means described hereinbefore also affords another advantage. Upon replacing a new tally-strip feed-roll. on the cross-rod, the right-hand stub-shaft 84 is slipped off the right end of the'cross-rod, since the left end has an enlarged knurled head 91. When this is done, the above-described construction will prevent the ball 89 and spring 90 in the right-hand stub-shaft from falling out of the stub-shaft. For mounting a carbon strip feed roll, designated as 92, in the frame 60, two upwardly-directed mounting slots 93 are cut in the side frameanembers 61 and 62, each having lower ends for receiving a righthand stub-shaft 94 and a left-hand stubshaft 95.

The stub-shaft 94 may include an inreaching substantially. square body-member 96 for engaging tightly in a square bore of the carbon-strip feed-roll core which may be like the core 80, an integral spool-head flangeinornber 97, an integral hub-portion 98 at the right of the flange-member 97, and a round bearing portion 99 coaxial with the hubportion 98 and engaging in the slot 93 with a working fit.

Fitting closely against the right-hand face of the member 61 is a second hub-portion 100. At the right of the last-mentioned hub-portion a hard rubber orwood finger-wheel 101 may be fastened in any suitable manner 011 a reduced stem-portion 102 integrally joined to the hubportion 100.

To latch the carbon-feed-roll 92 on the frame 00 against accidental displacement, as might be caused by sudden return of the usual platen-carriage, a latch-piece 103 (see Figure 3) is pivoted on a screw 104 in the frame-member 31. The upper end of the piece 103 is shaped to fit snugly down on the hub-portion 100 and has a finger-piece 105 to raise the latch against the pull of an overcenter spring 106, which is also effective to hold the latch in released position. A stopiug-lOT is provided to prevent the latch from being pulled too far by the spring 106 when the stub-shaft 94 is not in place on the frame 60.

The stub-shaft includes an inreaching substantially square body-member 110, an integral spool-head flange-member 111 and a hub-portion 112.

To provide means to prevent accidental or too rapid unwindingof the carbon-strip C, a reduced coaxial key-portion 113 is integrally joined to the left face'of the hub 112 and has the shape of a cylinder which has had a segmental portion cut away to form a flat face, such face on the key-portion 113 being designated as 11 1. Integrally joined to the left end of the key-portion 113 is a coaxial stem-member 115 whose outer end is threaded to receive a knurled head nut-member 116. Engaging around the key-portion 113 is a knurled head bushing 117 which has a bore formed with a fiat element for fitting snugly around the key-portion 113, which is thus secured to the bushing for rotation therewith.

The bushing 11? has a round bearing extension 119 which engages with a working fit in a lower enlarged circular portion 120 of the slot 93 in the frame-member 62. The outer end of the bushing 117 has an enlarged bore for receiving a washer 121 and an inner tubular shell-portion 122 of the nutmember 116. Disposed between the nut-member 116 and the washer 121 is a coil spring 123, which it can readily be seen by inspec:

tion of Figure 6, is effective to press the bushing 117 and the hub-portion 112 against 1 opposite faces of the frameemember 62. The

above-described construction for keying the bushing 117 to the stub-shaft 95 is advantageous because of preventing the working loose of the adjustment of the friction means for preventing the accidental unwinding ofthe carbon C. v

As the typing proceeds the tally-strip A and carbon-strip G are wound upon a single roll designated as 130, which may have a pa,-

per-core 131. This core may be, if'desired,

the same as the core 80'from which all of a roll of tally-strip A has been unwound. The

1 core 131 has a substantially square bore 132 and is mounted on two coaxially-disposed inreaching stub-shafts including a righthand stub-shaft 133 and aloft-hand stubshaft 134. y a

The stub-shaft 133 may have a substantially square body-portion 135 which isof a shape a and size tofit tightly in the square bore 132.

ber 61 in a way to permit rotation ofthe stubshaft, the bearing portion 137 has a coaxial holetapped for receiving a screw 138 having suitable enlarged head for retaining a washer 139 against the right face of the framemember 61. 1

The stub-shaft 13 1 includes a body-memher 140 having a shape and size for fitting tightly in the bore 132. A coaxial. hub portion 14-1 is integrally joined to the left end of the body-member14r-0 and a coaxial bear ing portion 142 engages with a nunningfit in a round hole provided in the frame-member 62 and extends a short distance past the leftface of the same. A.co-axial, integral reduced portion 14-3 at the left of the hub portion 141 may be squarein cross-section for having keyed thereon a gear-wheel 1414 which meshes with the gear-wheel 68. y A re duced coaxial extension 14.5 is integrally I joined to the squareportion 14L?) and has. mounted thereon a hard rubber. or wooden finger-wheel 146. the latterbeing held in portion 1 18 may come against the gear 144 i a and help to hold the latter in place A spacing washer 149 may be placed around the proecting part of the bearing portion 142 to pre vent lateral movement of the St11b 3l1ktfb 134 relative to the frame-member 62.

It will be notedthatby the above-described construction; the stubshafts 133, and134 are secured to the} frame-members 61 and 62, respectively, for lateral adjustment therewith andare rotatably mounted, and both are operatively connected to the line-space lever 23 for rotation thereby. It will also be noted that to adjust my tally-strip device for a different width of tally-strip, it is not necessary to separately manipulate the stub shaft 133 or 134 in any way whatever, since they are moved closer together and further away by lateral movement of the frame-memhers 61 and 62. p

The above construction of the feed-rolls and wind-up roll, each of which includes two stubsshafts and a core engaging the shafts with a splined relation, provides rolls which are securely mounted in the frame 60. Moreover, the carbon-feed-roll and the tally-strip take-up roll can each be easily and positively rotated in either direction by force applied to thefinger-wheels at the ends of these rolls. i

It is a feature of the present invention to provide means for attaching any commonly used width of tally-strip A and a corresponding width of carbon-strip C to the windup roll 130. These means may include a pair a of inreaching fingers or stub-plates 150, one finger being fastened by a screw 151 on the perimeter of the hub-portion 136, and the other finger being fastened by a like screw 152 to the hub portion 14:1. The lengths of the stripswill preferably be such as will bring their inreaching ends approximately even with or slightly ast the inreaching ends of the stub- shafts 133 and 134. Each finger 150 will preferably be formed with a curvature transverse to its long axis which will make it substantially parallel to the curved periphery of the core 131.. i

The transversely-curved fingers 150 will be spaced away from the periphery'of the core far enough to permit the tally-strip A and overlying carbon-strip C to be easily insorted between the fingers and the core. In

most cases, it is preferable to space the fingers far enough away from the core 131 to permit the tally-strip and overlying carbon-strip to be straightened out, as indicated in'Figure 8,. and pulled up beween the fingers 150 and y the core 131 without causing a bend in the strips at the fingers, which would be detrimental to the thin relatively weak carbonstrip especially if already used. Furthermore, it is desirable to prevent the carbonstrip from rubbing against the fingers when straightened out and moved up or back relatively to the core 131. Thepositioning of the fingers in this way also permits a special advantagewhich will appear hereinafter. V

To secure the tally strip A and carbona strip G to theroll 130, short sections of the leading-end portions of the strips, after being passed between the fingers 150 and the;

ceive the blade 155 with a snug fit is vided in the frame-members 61 and 62. A

screw 158 en a es in a ta aed hole in each frame-member 61 and 62 and binds the blade 155 in the frame 60.

If desired, the blade 155 used with one of my. tally-strip devices may be long enough for severing the widest tally-strips to be handled by that device, and when a narrower tally-strip is to be used, the frame-members 61 and 62 may be moved up nearer each other the desired distance and one or both ends of the knife-blade can project out beyond the frameemembers 61 and .62. In many cases, however, two or more knife-blades 155 of different lengths will be furnished with each tally-strip device, the lengths of the blades corresponding with the widths of the tallystrips ordinarilyto be used in the device.

In winding up the tally-strip A and the overlyingcarbon strip C on the same feedroll 130 some means is desirable to prevent typing of data on a work-sheet, such as the bill 15, after the rear end of the tally-strip (under the carbon-strip) has been unwound from its feed-roll 82 and drawn past the printing line. Should this occur no tally of the data will be made and also the platen may be'smudged with carbon. To enable an operator to overcome these dificulties, it is preferred in my advice to have the tally-strip A project outwardly a short distance beyond one or both side edges of the overlying car boil-strip C (as is indlcated in Figure 4), so

that the tally-strip is always visible.

The use of my tally-strip device affords a special advantage when it is desired to use the carbon-strip C over and over again, is often done. hen a desired list of data has been copied on a section of the tally-strip A the roll 180 will be reversely rotated by one hand turning the finger-wheel 146, the clutch teeth 71 having been first disengaged from the clutch-teeth 72. Then with the other hand the typed section of the tally-strip A and overlying carbon-strip C may be pulled forward, as indicated in Figure 7. The fingers 150 are then revolved around to come at the front of the core 131, as shown in Figure 8, and the typed section of tally-strip A and the overlying used section of carbonstrip C are pulled upwardly between the fingers 150 and the core 131 until the last item typed on thetallystrip is a suitable distance above the knife-blade 155. Then while the the carbon-roll 92 is reversely rotated by the operators right hand turning the finger-piece 101 until the leading edge of the carbon-strip C is only a short distance above the fingers 150, as indicated in Figure 9.

The carbon-strip G and the tally-strip A are then folded over the fingers 150 and the wind-up roll 130 is rotated ahead by the linger-piece 146 until the tally-strip is brought to proper cutting-off position relative to the knife 155 on which it is severed in a wellknown way, as indicated in Figure 10.

It will be noted that at all times during the above-described manipulation of the tally-strip A and carbon-strip C, they are both left under control of the finger 150, whereby they do not have to be reinserted after the tally-strip is cut off. It can also be seen that when desired the tally-strip A and thecarbon-strip C may be severed-together on the knife 155, and the severed portions may be removed from the tally-strip device while still wound on the core 131.

This result can be accomplished by simply unloosening the set-screw 66 and moving the frame-member 61 to the right, whereupon the right-hand finger 150 will be withdrawn from the roll of tally-strip and carbon-stri p wound on the core 131. Then by moving the roll 130 to the right, it will be disengaged from the left-hand finger 150. V 7

,It is oftenrequired in typing bills 15 to keep a record of the bills on a record-sheet 160 whiclrwith an overlying carbon-sheet 161 may be fed through the typeWriting machine under the bill 15 and over the tallystrip A. To permit use to be made of the arrangement of the tally-strip A and carbonstrip C, as shown in Figure 4 and explained above, when using arecord-sheet 160, the rightedge of the tally-strip A should extend slightly beyond the right edges of the bill 15 and the record-sheet 160. 7

Variations may be resorted to within the scope of the invention, and portions of the improvements maybe used without others.
