There is a very considerable extent'ot typi-iwritingz pertorn'ied in which, for various reasons, it is desirable and also the practice to count the words, including numbers, that have been written upon the machine and this I provide means to accomplish, a torin of which means being shown and described herewith. A simple method to ac ooniplish this counting consists in arranging me? is operative by the various keys, with coin n exceptions, of the typewriter keyboard. an dv in my method of word counting l utilize the first stroke in the writing of the init al letter of the word to actuate a regisleri means which. when the following lettor keys in the spelling of a word are actuated. are ineffective, means being provided to auion'iatically interrupt the operation of the registering means after the initial letter stroke or the key in starting the writing of a word. 7

Key lever actuated instrumentalities are, therefore, combined with the machine, and in the present en'ibodiment such instrunientalities include a plurality, in this in stance two, of what might be termed K 5 l combs. One ot these combs 2 is shown in Figure 2 as having a number of upwardly extending teeth and these teeth are so disposed along the comb bar as to register with respective of the letter keys and their lovers 4; of the typewriter; which letter keys are identified in Figure l by their respective symbols as are also other keys such as a key showing a and the associated mark, another key showing the upper and lower case period and others as may be mentioned hereinafter. It will be noted that the comb teeth 3 are arranged in spaced groups or fashion the intervening spaces providing for the depression of contiguous numeral key levers 5 without causing operation of the comb 2 as is done by the-operation of any of the levers when they engage the contiguous comb teeth 3.

In Figure 3 there is shown a comb 6 having upwardly extending teeth 7 which are disposed so as to be engaged by the downwardly pressed numeral key levers the numeral keys being appropriately designated in Figure 1. An important feature of the invention is to provide means operative by the shitting ot the usual typewriter carriage from lower to upper case position so that certain of the characters combined on the number type bars, not here shown, and which characters are ordinarily as tollows: it, 55, and &, may be counted, when the keys are struck as words to be included in the total, shown by the registering means of words written.

It might be stated at this point that there are certain symbols which will not be counted as words when their respective keys are operated, and these include the following: the llllilGl'SOOFt, mark usually associated with the nun'ieral key (5, the apostrophe, the two parentheses marks and the asterisk and the hyphen. Also not included as words are strokes of the colon, the semicolon, upper and lower periods, the question mark and the comma and the diagonal line. Strokes of the traction keys in the lower and upper case positions will counted. as words and the 1'S}'H.C 5'lt i con'ibs are accordingly provided with teeth to he engaged by the appropriate evers. To accomplish the operation of the nun'ieral comb 43 when the carriage has been shiited and when certain oi the symbols as sociated wi h the numeral keys are actiuited, certain 'of the teeth '7 ot the comb (i are shown as wider than others, the widened teeth 7 b inst engagezable by given keys when the nun'ieral cou'ib (3 shifted, but clezu-ing the keys over the arrow teeth.

The letter comb 2 extends longitudinally beneath the keyboard and is supported on the outer ends of arms 5: which are secured on a rock shaft 9, the ends of which are journaled in bearings, one of which is indicated as a plate 10 having a bottom leaf secnredby screws 11 and 12 to the bottom of the side frame members 13 of the typewriter frame, which is usually provided with tapped holes to receive screws for various attachments not necessary to be described. The opposite end of the rock shaft 9 extends into an upwardly extending bearing plate 15 forming a portion of the casing including the registering means and forming suitable bearings for parts thereof. The rock shaft 9 has securedvto it a forwardly and downwardly extending lever 16 and this is provided with a laterally projecting A rock shaft 22 and extends through the holpin 17 engaging a lever 18, the swinging end of which is provided with a slot 19 in which the pin 1? slides and engages the edge walls of the slot. The lever 18 has a hub 20 which is secured to a hollow shaft 21, Figure 9. This hollow shaft 21 is rotatively supported on an inner rock shaft 22, each of these shafts being journaled in upstanding plates of the casing above referred to and generally indicated at 25. The train of levers connecting the letter comb 2 and the hollow shaft 21 above described are all controlled by a recovering device shown as including a spring 23 which is attached to the swinging end of the lever 18 and to a fixed part as a pin 24 of the casing 25.

It will be seen that when any of the keys, having levers engaging the letter comb 2, are depressed that the hollow shaft 21 will be rotated slightly against the tension of the spring 23 and as soon as the actuated key is released, the letter comb train is recovered or reset to the normal position unless otherwise prevented as will be hereinafter explained, by the action of the spring 23.

The numeral comb G has attached to it rearwardly extending arms 26 which are secured on a rock shaft 27 extending longitudinally beneath the bank of key levers and having a 10 and also having a bearing in the side plate 15 of the casing The rock shaft 27 is designed to have longitudinal. movement and is provided with stop collars 28 which respectively engage contiguous cam bars 29 which are slotted at 30, Figure 9, to ride upon the shaft 27 transversely, ant which, when actuated, thrust the shaft 27 in the direction of the arrow, Figure 10, against the reaction of a spring 30 normally pushing the shaft 27 to a. given position so as to hold the teeth 7 of the comb 6 in register below the numeral key levers. 'lhere is one of the cam bars 29 adjacent each end of the rock shaft 27, and these form means operated by the shift keys of the typeer l-zeyboard to accomplish the shifting of the rock shaft 2'? so that the teeth 7 of will be present under certain of he stroke of certain of these keys bearing in the attaching platev icral keys to accomplish a registra with a hub 35, and this is secured. as by a set screw 36 on the previously mentioned low shaft 2i. The lever train connected to the numeral comb G is normally retracted to an initial position by consisting, in the present case, of a spring attached to the swinging end of the lever and to a contiguous fixed part, as pin mounted in the casing 25.

From the above it will be seen that I have provided a mechanism, including instrumentalities operative by certain of the several key levers of the keyboard and wherein a means is provided also for the axial shifting of one of the so as to give it two positions and enable the operation thereof by a set of keys when these are actuated in either lower or upper case functions.

1 have provided also a totalizing or registering means operated by the aforesaid organization so as to keep count of the number of words or actions which may be counted as words during the operation of the typewriter, and a simple, practicable, effective, reliable and substantial form of counting means is herein shown in one embodiment as follows:

In the casing 25 there is journalod a transversely extending shaft {t0 which, in the present case, is shown noncircular and on its outer end is provided with a pinion ll engaged by a segment of a gear l2 pivoted on a stud 43, Figure 6, the hub of the segment 4-2 being flattened as at 44:. The segment is provided with a handle 45 pr.0- jecting, outwardly from the casing and enabling the ready operation of the rack 42 which is so proportioned as to give the pinion 1:1 one complete revolution for each fall stroke of the segment. Nonrotatably mounted on the shaft 40 is a series of discs or carry-over wheels provided with recessed peripheral portions 47 terminating in hook-like ends 48, Figure 16. The several carry-over discs 46 are shown as countersunk in the adjacent faces of totalizing wheels 49 which are axially spaced along the shaft 40, and each of which is provided with a rigid ratchet wheel 50. The ratchet wheels substantially form hubs for the totalizing wheels 4:9, and these hubs are turnably instrumentalities any suitable means tlt) mounted on spacer bushings 51 through which the pinion shaft extends, thus enabling the rotation of the totalizing wheels 4.) independently of the pinion shaft 40. Spring 42' pulls segment 42.

On one side face of each of the totalizing wheels 49 there is provided a pivot pin 52 and on this is pivoted a transferring pawl 53 which has a hook end normally pressed dmvnward by a spring so to engage a tooth of the ratchet wheel of the totalizing wheel 49 of the next higher order when this is permitted by the carry-over discs to. The pawls 555 are each provided with a laterally extending pin 55 extending into a pocket 56 provided therefor in its totalizing wheel it), the pins 55 projecting through the respective wheels and being engaged by the springs which are provided on the opposite side of the wheels. as clearly shown in Figure 17. It will thus be seen that if the unit. totalizing ratchet wheel 50 is given an impulse from the zero position. it will turn its respective totalizing wheel 49 one step. After nine steps have been made by the totalizing wheel. its transfer pawl 53 rides off of the periphery of the carry-over or carrying disc l6. and as the pin 55 of the wheel pawl drops into the recess 4;? of the next higher transfer wheel 46, the hook of the pawl 53 engages the contiguous tooth of the next higher ratchet wheel 50. And then on the tenth stroke of the lower order of totalizing wheel 49, the hook pawl of the actuate-d wheel becomes operative upon the engaged ratchet 50 and will turn this one step. The next successive movement of the lower order totalizing wheel causes th ratchet pin 55 thereof to ride out of mesh with the engaged ratchet 50 and clear the. same without a transferring action; this be ing caused by the cam action of the face of the recess 47 in the carry-over disc which is held stationary by its shaft 41-0.

Check means are provided for preventing reverse action of the transfer or carry-over ratchets 50, and such means is shown in Figure 16 as including a series of upwardly extending latches 57, the lower ends of which are pivoted on a pivot rod 58. The brake latches 57 are normally pulled into locking position by a yielding means such as a spring 59 fixed to a convenient fastening at one end and attached to the respective brake latches '57 at. the opposite end. hen the several transfer ratchets are rotated in one direction their brake latches yield, but the ratchets are prevented from a reverse rotation by interlocking of the brake latches with the teeth of the ratchets. The brake latches consists of simple upstanding members which are guided and laterally sup-.

ported in guide plates 60 and 61 which are slotted to receive the latches. In the presentconstruction, the guide plates are rigidly secured. to each other in superposed position and are attached to the contiguous ends of parallel arms of a yoke frame 62 which s pivoted on the pivot shaft 58. and when any one of the ratchet wheels 50 is rotated this results in a tilting of its brake latch 57 and this engages the upper guide plate 60. which being secured. to the yoke frame (ii? causes this latter to tilt upwardly at its iuner end. Secured on the inner end of the yoke frame 62 is an upwardly extending member (33 which has the function of locking means which actuate the unit or first ratchet wheel of the series.

The totalizing mechanism above described is adapted to be actuated by the action of the rock shafts 20 and 22 which are actuated by the lever combs above described. These rock shafts 20 and 22 extend into the casing of the totalizing mechanism and the tubular rock shaft 20 has secured to it an upwardly extending lever 70, Figure 12, and this is provided with spaced horns 71 projecting from its upper end, and these horns are adapted to swing toward and from a stop pin 72 secured to the contiguous wall of the casing 25. The inner rock shaft 22 has secured to it a lever arm 73 which has upward-- ly projecting horns 74 also designed to engage the stop pin 72.

The lever is pivotally connected at 7 5 to the contiguous end of a horizontally extending bar hereinafter called the ram 75, the forward end of which is provided with shoulders or teeth 77, the foremost one of which is, in the retracted projection of the ram, designed to rest contiguous to the lowermost tooth of the first ratchet wheel 50' of the counting mechanism. The ram 76'is normally pulled to a retracted and upper engaging position by a spring 78, Figure 11, and is thereby held in engagement with the primary ratchet wheel 50. Upon operation of the letter comb 2, the hollow rock shaft 20 is oscillated and this results in forcing the lever 70 forwardly and throws the ram 7 6 forwardly as is shown in Figure 13, so that the primary ratchet wheel 50 is turned one step. This initial step rotation causes the unit counting wheel 49 to take a one-tenth revolution so that its peripheral index number will be set to indicate a stroke of a key lever.

A feature of the present invention includes means whereby the actuating ram 76 is locked against action except by the first stroke of a letter key in the spelling of aword or in striking a single letter word, such as for instance the letter I which is, of course, acomplete word. The mechanism is designed to permit the writing of a word of any number of letters and to cause register of the whole word but once. This is accomplished by means under the control of the space bar 100 of the typewriter.

ly shown in Figure 15,

The space bar control means includes an automatic latch H)" which is secured on a rock shaft 81 extending horizontally under the lmyboard. The extended end of the rock shaft 81 is provided with a lever arm 82 having a lateral shoulder 83 positioned beneath the contiguous lever arm 101. ot the space bar 100, so that when the space bar is pushed down. its lever ltll engages the lever arm S2 of the rock shaft 81 and this is rocked to litt the latch SO-trom engagement with a pin or shoulder 84. provided on the actuating lever 70. The rock shatt 8i with its latch 80 is yieldingly pressed into locking position by may consist of a compressed spring 85, Fig ure i-lengaging a lever 86 secured on the rock shaft- 81. lVhen the actuating lever 'it) is thrown on its operating stroke to push the ram 76 and turn the primary ratchet wheel 50 the pin 84 passes beneath the contiguous hook of the latch 80 as is shown in Figure 19 and the latch becomes effective instantly to engage the pin'Sl and hold the lever in the thrown position so that the lever '70 cannot return to idle position as pressure of the finger is removed from the key of the keyboard which initiated the action of the lever 70 and its ram 76. Thus the holding latch 80 remains eiiective in looking position until it is disengaged by action of the space bar 100. as shown in Figure 1s From this it will be seen that as the initial key of any word is struck the first action is utilized to actuate the counting mechanism and the ram 76 is held out of commission while the rest of the letter keys. necessary in the spelling oi a worth are actuated. Where the word consists of one letter or any multiple, as soon the space bar 100 is struck in completing the word and to shitt-the carriage of the typewriter. then the locking latch 80 releases the lever T 0 and its ram 7th and these parts are restored automatically to the idle position in readiness to be again actuated.

The inner shaft .22 is actuated by the numeral and certain other keys and there'tore rocks the lever 73 to which is connected a ram or push rod 87 which projects forwardly and operatively engages the prin'iary ratchet wheel 50 in the same manner and action as with respect to the previously described ram 76: these two rams lying side by side beneath the primary ratchet as clearv each having a spring T8 to yieldingly hold it in engagement with the primary pinion 50. As distinguished from the action of the lever 70. the numeral comb actuated lever 73 is not designed to be locked out ot action as is the lever 70, since it is desirable to count each stroke of any numeral lever excepting the O lever as one complete word. For instance, in the typing of the number 999,

suitable means which actuating lever 70 and the machine would register the three separate strokes of the lever 9 as words. In the writing. of the numeral 10, the operation of the L letter would become ell'ecto actuate the primary ratchet wheel so ot the unit counting wheel and then the 'iollowing stroke of the 0 lever when made would not be counted as a word for the reason that the numeral 10 is, in the present system, considered but one word. A further special matter is that the numerals 11 to 19 are counted as one word and this is secured by providing means for cutting out or negativing the action of the key levers upon the counting means.

The cut-out means includes a key lever 88 tulcrumed on a rock shaft 89,-Figure 11, and being normally thrown to the normal position as by means of a spring 90. Secured on the rock shaft is an upwardly extending lever arm 91 which is provided with a laterally extending pin or shoulder 92, and this extends transversely across and somewhat above the upper edges of the rams 76 and 87. By pressing down the cut-out lcver 88, the lever arm 91 swings down and is operative to first depress the ram '76 so as to carry itnout of engagement with the unit count wheel ratchet 50. Therefore, it will be seen that it a letter key of the keyboard is struck while the ram i6 is disengaged by the cut-out means, the primary or unit ratchet wheel 50 will. not be actuated. Therefore, this device serves to neutralize the action of the mechanism when any of the letter keys are actuated. The cutout device. is adapted to be locked in eliective position and automatically released, and to that end the lever arm 91 is shown as provided with a latching pawl 93 pivoted at 94ron the arm 91. The latch pawl 93 has a shouldered end 95 which is designed to interlock with a stop pin or shoulder 96 lined on a convenient rigid portion of the counting mechanism casing or frame. The cut-out key 88 is designed to have three several positions, the first of which is the idle or normal position shown in full lines in vFigure 11; the second of which is the dotted line position of Figure ll wherein the locking pawl 93 is in engagement with the stop shoulder 96 which prevents the cut-out lever 88 from automatically resuming normal position until it is automatically released from its second position by suitable means. The automatic releasing means includes a kick-ofl pin or shoulder 97 secured to 01' formed upon the in such position that when this lever 70 is actuated it will en' gage the contiguous cam shaped end of the lever 93 with the result that this lever is litted from looking engagement with the shoulder 96 and the cut-off lever 88 is automatically restored to its normal position.

As above explained, the shifting of the cut-out lever to the second position is effected to negative the operation of the ram 76 upon the unit ratchet wheel 50.

It is desirable, in some cases, to negative not only the effect on the counting machine of the letter keys of the keyboard, but also to negative all of the other keys that actuate the comb 6. To that end the cut-out lever is designed to have a final and third or lowermost position as is indicated diagrammatically in Figure 19, at which time the disconnecting pin 92 of the lever arm 91 engages and depresses the ram 87 also fmm the unit or primary ratchet wheel 50. l hercfore, all of the keys of the keyboard may be operated without any actuation of the counting mechanisi'n. The cut-out lever S8 is designed to be locked in its final keyboard cut-out position and this is readily accomplished by providing in the shank of the lever 88 an aperture. 99, and when the lever 88 is in its lowermost position, it can be shifted slightly laterally to engage a contiguous projection as the end of shaft or rod 58 mounted in the casing or frame 25.

In typing the numeral 11, the letter key L is struck once. to secure a word count action of the counting means and then the cnt out key 88 is depressed to the second position to negative the second stroke of L lever in completing the numeral 11. This second letter key stroke unlocks the pawl 93 and releases the key 88. 11 is thus registered as one word.

In typing numerals 12 to 19 inclusive these are each counted as one word by first depressing the cut-out lever to second position and then striking the L key. This restores the cut-out key 88 without an action of the counting wheels, The key of the next digit is then struck and this action is registered as a word by the counting mechanisl'n.

It is desirable to provide means for the manual actuation of the word counting means in various uses of ordinary or spe- (ial orcurrcinrc. For example, when typing the numeral 2039 the naught is not registered as a word since it is not desirable to register 10 nor multiples thereof to as more than one word.

This supplementary adding means in cludes a lever pivoted at its rear end on a pivot pin 106 and normally elevated to an uppermost position as by a spring 107, Figure 6. The uppermost position is determined as by engagement with the exposed end of the shaft 40 of the pinion 41. Under the rear end of the adding lever 105 is a linger 108 which is fixed on the center shaft 22 to which is secured the upwardly extending lever 73 actuating the ram 87. Therefore, by the application of a finger to the adding lever 105, this, when presseddownwardly, rocks the shaft and this in turn gives a stroke to the ram 87 and the unit ratchet wheel of the counting wheels is given a step. It will be seen that the adding key 105 can be depressed at any time and will. result in the addition of an additional word to the total registered on the totalizing wheels 49. This adding lever has any suitable stop device to limit its downward movement such, for instance, as a lug 109 secured to its under edge and which is designed to engage the bottom of the housing 25.

All of the totalizing wheels 19 are adapted to be restored to an initial blank position, the cipher indexes thereof alined preparatory to beginning a new count, and this is accon'iplished by the simple forward pulling of the stem -15 which is connected to the segment 42, this in turn spinning the clearing shaft 40 whereby the several clearance discs 16 are concurrently rotated to bring the clearance shoulders 48 thereof into engagement with the carry-over pins 55 on the pawls or clicks 53 of the several totalizing wheels 19.

As previously disclosed, the hub of the clearance segment 42 is provided with a flattened surface -14, and this is designed to depress a tripping arm 110 that is secured on the contiguous end of the latch rock shaft 81 so that in the event that at the moment the counting mechanism is cleared by the segment 12, if the locking latch 80 is hold ing the lever 70, the latter will be released by the action of the tripping arm 110 when the segment 42 is thrown forward in the clearing stroke. This restores the entire mechanism to the normal ready position in (OIKiltlOIl for the next keyboard action.

Means are provided for preventing the overthrow of the several totalizing wheels 4:9 when the clearing segment i2 is thrown and which means is shown as inchuling in Figure 16 a transverse bar 111 disposed. substantially in the horizontal plane of the axis of the wheels 19 and which is secured to the upper ends of upwardly extending lever arms, 112 on a rock shaft 113. A yield ing connection is made between the bar 111 and a contiguous shoulder, as for instance the inner end of the stem 45. This yielding connection is here represented as including an upwardly extending spring arm 114 having a transversely bent end 115 playing in a window 116 in the side wall of the casing 25; the spring end 115 being engaged by the swinging end of the stem 15 as the latter is moved to clear the totalizing mecha nism. The spring 114. then becomes yieldingly effective to throw the stop bar 111 so that prongs thereof will project into the path of the transfer clicks 53 of the totalizing wheels 49 as these are restored to the clear position.

eastern The key levers of the keyboard which are respectively designated one by a comma and a question mark, one by upper and lower case periods, and one by a colon and a semicolon, are not designed to actuate the counting mechanism, but instead are utilized as a means alternative with the space bar 100 to release the lock latch 80 after the completion of a word in a manner similar to the releasing of the locking latch when the space bar is actuated. Means for utilizing these just mentioned keys includes an engagement strip or plate 120, Figures 1 and t, which is secured to the space bar lever 101. This ongagement device is in the form of laterally extending lugs and may be attached to the space bar lever 101 as by a simple form of clamp 121 in such position as to be engaged by this space bar lever when it is actuated.

When the shift keys (so designated in Figure 1) are actuated, the cams 29 are thrown to effect a longitudinal movement of the rock shaft 27 to secure the object above described of placing the numeral comb 6 so that certain of the numeral keys of the keyboard will be utilized in action to actuate the counting means. The cams 29, Figures 9 and 10, are actuated by levers 122 of the respective shift keys. These levers respectively engage crank levers 123 mounted on pivot pins 124, the lower ends of the downwardly extending arms of the cranks 123 being connected to the contiguous ends of the cam members 29. Downward pressure on a shift key lever 122 results in pulling a respective cam 29 formirdly and this will shift the rock shaft 27 axially to the desired position. The usual returning movement of the shift keys effects a restoration of the earns 29 and releases the rock shaft 27 so that it will return under the impulse of its spring 30 to the normal position.

It will be seen that any tendency of the ratchet wheels to be overthrown by the action of the rams will be prevented by the upward movement of the abutment member 61 which is actuated by the ratchets when they tilt the upwardly extending latches 57, since the member 63 is designed to encounter downwardly extending means in the form of lugs on the lower front end portions of the rams 76 87. The member 63 thus forms a stop to prevent the rams from springing downwardly out of mesh with the contiguous ratchet. The downwardly extending shoulders 7 6 on the ram 76 clear the abutment member 68 when the ram 76 is in its locked position under control of the latch 80.
