TYPE-WRITING MACHINE;

To all whom it may concern:

Be it known that l, (Ere B. Yaw, citizen ofihe United States, and resident of Arlington, inthe county of Hudson and State 01'- new Jersey, have-invented certain new and f useful Improvements in Type-Writing Machines, oiwhioh the following is a specifica f lll-y invention relates to typewriting ma- :chines and "more particularly to work regis- 1 tering. mechanisrnfor such machines.

fsometimes operators are paid by piece workv and 1t 18 desirable-t provide some i-kind of a check upon the operator's other thanby a; inspection and keeping of i -separate accounts of the actual work done the diil'erent oeerators'. Then a-ain rol prietors are sometimes anxious to keep track of the amountnf work done "by different operators-without each operator knowing how much work has been done bv each key number.

of the other operators. Heretofore it has been .common' to provide automatically actuated word. counters usually actuated by the space key of the machine and intends. ed to register a number of words written as represented by the actuation of the space key, counting a word for each space or each actuation of the space key. These and all prior word counting devices are open to objections. Thus, the. operator at all times knows how much is registered on the machine and how much work is registered on every other operators machine. Moreover, it is a simple matter in such machines to repea-tedly actuate the space key and thus operate the indicator to register one word written for each actuation of the space key without there being any work produced. Then again, in all such word counting constructions, sofar as I am aware, the word register was actuated by the print-in keys or by the space key; thus placing additional work upon these keys and altecting the touch? The objects of my invention are to,overcome the above and other di'tficulties and to provide simple and eflicient work register .ing.mechanism by which an indication of the number of words or lines'written upon the machinc'may be, determined only by. those persons who are in possession ofthe Specification of Letters Patent.

. To the-above and other ends Patented Dec; 26, 1911.

Application filed November 19, 1809. Serial No. 528,965.

hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reterence characters indicate corresponding parts in the various views. Figure 1 is a vertical central fore and aft sectional view ,of a No. 10 Remington machine embodying my invention, a sufiicient number of' parts of the machine being shown to illustrateq ny invention in its embodiment there- 'in. Eig. 2 is an enlarged detail fragmentary plan view partly in section of the work registering mechanism and some of the associated parts. Fig. 3 is a transverse sectional view of the work register taken on the line a=-a.- of Fig. 4 and lookingin the direction of the arrow at said line. Fig. 4 is a longitudinal sectional view of the work register taken on the line y-y of Fig. 3 and showing the work register and some of the associated parts.

I have shownmy invention embodied in the resent instance in a No. 10 Remington 'mac ine, although some of the parts are only conventionally represented in the drawings. It should be understood, how ever, that the invention may be embodied in various styles of type-writing machines.

The frame of the-machine comprises a base 1, corner posts 2 and a top plate 3. Key levers 4 are fulcrumed at 5 and are pro vided with the usual finger keys 6. Each key lever is connected to a link 7-which in turn is connected to a sub-lever 8.' The rear end of each sub-lever is connected to a pull link 9 which in turn ispivoted to a type bar 10. The type bars are mounted to strike upwardly and rearwardly against the front face of a platenll. A universal bar 12 extends transversely heneath-the key levers and is supported at its ends onupwardly extending links 13 pivoted at 14 to rearwardly extendin arms 15' which project from a rock sha 16mounted in hearings in the base 1 of the machine. A centrally disposed rearwardly extending arm 17 on the rock; shaft is connected to a link 18. The upper'end of the-link 18 is connected rocke flp-mounted-upon-arook'shait 21 end to a bracket plate 23 which supports the dog rocker and is connected at its opposite end to a projection 24 on the dog rocker.

' The dog rocker carries at its upper end a feed dog 25 pivoted at 26 (see Fig. 4) to the dog rocker. A spring 27 normally maintains the feed dog 25 in the operative position shown in Fig. 4. The feed dog, however, is adapted to be moved downwardly out of operative position against the pressure of the spring 27 as will hereinafter more clearly appear.

The platen 11 is carried by a carriage. 28

'mounted on roller bearings 29. Lugs 30 are secured to the carriage and have rearwardlv extending arms 31 pivoted thereto. A feed rack 32 is secured to the rear ends of the arms 3 and meshes with a feed pinion 33. .This pinion is secured to the forward end of 2 1 a shaft 34 mounted to turn in a bearing 35 secured by screws 36 to the-top plate of the machine. A hub 37 is secured by screws 38 to, the rear end portion of the shaft 34 and .is provided with a central web portion 39 to 1 ofthe carriage from left to right are etfeeted by the intermittent actuations of-the feed dog 25, as the feed dog moves forwardly and back between the escapement wheels. When, however. the carriage is returned to the right the escapement wheels will receive a backward rotation and the feed dog will be moved away from the escapementwheel and against the pressure of its spring 27 by the contact of the rear inclined faces of the tecthof the engaged escapemcnt wheel with the rear face. of the feed dog. The

parts thus far described correspond substantiallv to those embodied in the No. 10 Remington machine and further detailed descrip tion thereof is deemed unnecessary.

The rear end of the hub 37 of the duplex escapement wheel is provided with a beveled wheel 43 which meshes with a. corresponding beveled pinion 44 fixed to a hollow shaft .5 From an inspection of Fig. 4 it will be seen that the hollow shaft is supported upon a. shaft 4(l containcd within the hollow shaft and bearing atone end as at 47 in an opening in 'a racket arm 48 bent up and forming. part of a bracket plate 49 secured to the top plate of the machine by screws 50 and 5]. The opposite end horlion ot the shaft- 46 is supported in a bearing 52 of a cylindrical lunising 53 which contains register wheels 54. 55, 116. 57,59. The register in the present instance is shown as a Veeder c vclon'u-tct" although an other suitable form of register may be employed. The c v lindrical housing 53 is secured to thehracket BEST avaltaetsco'ei plate 49 by a serew 59 and is provided with a sight opening through which the markings on theregister wheels may be seen. The hollow shaft 45 is provided with a cylindrical housing 60 closed at one end by a disk 61 which connects the housing to the hollow shattand hearing at its opposite end against the fixed housing 53. This cylindrical housing 60 contains two pawls, one a. pawl 62 pivoted on a headed screw 63 to an end of the fixed housing 53 andmounted so that the force of gravity will maintain the engaging nose of the pawl in engagement with a ratchet wheel 64 formed on the shaft 46 and contained within the cylindrical housing 60. The second pawl 65 is containedvwithin the housing 60 and'is pressed into engagement with the ratchet wheel 64 by a. spring 66 secured at 67 to the housing 60 and pivoted to the 'disk 61 thereof on a. shouldered headed screw 68. From an 'inspectionof Fig. 3 it will be seen that these pawls extend in opposit-edirections. and the pawl 62 being car- 1 ried-by the fixed casing engages the ratchet wheel and prevents a rotation of the ratchet wheel. and the shaft 46 forming a part thereof, in a direction opposite to that indirated by the arrow in Fig. 3. On the other hand. the pawl 65 is carried by the hollow shaft 453- 01 the housing 60 connected therewith. and when said shaft is rotated in the direction of the arrow in"Fig.- 3, the pawl 65 will cause the shaft 46 to'be rotated in the same direction. The shaft 46 extends centrally thronghthe housing 53 and the shaft is fixedly connected atits outer end with an eccentric 69 by 'which motion is transmitted to a-gear70 which surroundsthe eccentric and this gear in turn transmits motion to a gear 71 carried by the first of the register wheels 54. A part of the gear 70 likewise meshes with a gear 72 fixed to the inner hearing portion 73 of the fixed housing 53.

The gears 71. 72 and 70 constitute difi'erential gearing which causes. in the example shown, asinglc movement of the register wheel 5-1 from one number 74 to the next i for each fifteen revolutions of the shaft.46 in the direction oi the arrow in Fig. 3. The shaft 46 and wheels controlled thereby are prevented from-rotating in an opposite dis/ rection. as herembetore expla ned, by the.

pawl (32. (arrving wheels 76 are mounted on a shaft 77 fixed at. one end in'the fixed gear opposite endwall of the fixed housing 53. 'lhese carrying wheels are of the usual construction and mesh with gears on the register wheels to successively actliatethem in the well known manner. The cyclometer or register in the construction shown in the present instance is so arranged that the units wheel 5 will he turned from one numher to another during the writing of forty words calculating the five spaces to a word.

72 and fix'edatits opposite end in the BEST AVAlLABLE COP.

In other words, it requires two hundred strokes on the printmg keys or space key to lone to the register so that one will be nd: to the register for each two hi ndred strokes on the printing or space key. This number may-be readily varied either by changing the character of the Veeder cy- 1 meter employed or by changing the gear- 11;; by which motion transmitted to the syclomcter or register, Thus, by changing the relation of the gears and H the num her of key operations required to add one to the register mziy be varied.

From the foregoing description it will be F understood thzit'the register is only actuated by an operation of the esca ement mechanism and can'notbe ectua ed in any other manner. It will likewise be understood that the register is only actuated during the letter space movementof the carriage from right to left or in the direction of its feed by its spring drum 78 and band 79nnd this only when the carriage isunder control of its eseapement mechanism. If, for instance, the co rriage be moved through a tabulator or otherwise than through the control of the escapement mechanism, it necessary to disengage toe teed reel: 32 from its escepement pinion 33 and this disengagement is effective to disconnectthe carriage from the register so that the movements of the carriage t this time do not effect the regis I l tor. Yvloreover, will be seen that the reg- Ester is actuated by the power employed to more the carriage and that the work of actuating register is not borne by the finger keys so that the touch of the keys is not eltected. It Will likewise be seen that it would require much work on the part of the operator to run up the register with the space key as would be required to actually produce a corresponding amount of work upon the machine as'each actuation of the space key corresponds only to the imprint of a single letter.

it will he understood therefore Thzit l have provided simple, comparatively cheap and eiicient means for registering work produced. upon the machine without persons being able to determine theamount of work produced unless they are in possession of the key number Unless, for instance.

the operator knows that in the particular example indicated the adding of one to the register represented the writing of forty words, then the operator would not know. how to calculate from the register the amount of work produced, and yet the, reprietor or other person in possession the key number would at a glance be able to tell just how much work had been performed by the operator. 7
