As usual inthe typeof machine here illustrated the registering or accumulating.

nated' by the numeral 2, -the accumulating wheels are designated by the numeral 3, and

the printing/platen is designated by the' numeral 4f The numeral designates the customary slide bars or strips which carry the registering racks.at their front ends and are connected at their rear ends with the type-carriers, and the numeral 6 designates the springs which operate to advance said bars or strips. The operating handle of the machine is indicated by dotted lines in Fig. 1 and the' numeral 7 designates the stub shaft to which that handle is secured. A crank-piece 8 also secured to said shaft is connected by a link 9 to a full-stroke sector 10 fastened to a rock shaft ,11 at the rear of themachine.

Referring first to- Figs. 1 tn and the matter of reducing the spring resistance to the handle pull the numerals l2 and 13 designate the usual pair of power springs which are connected to the rock shaft- 11 and against .which the handle. is pulled, said springs functioning to complete the operation ofthe machine when the handle is releasedvaftcr being' drawn fully forward. The right hand spring 12 is 'connected as usual by a rod or wire 14 with a crank arm 15 secured to and depending from the rock shaft. 1l. The left-hand spring 13 is the one whose resistance is to he removed-and consequently it is not so connected with said rock shaft. The latter has another dependingl cranlcarm 1G secured upon it near its lett-hand end but the spring 1S not des'ectly connected to that crank arm. lts

.-'. connecting wire or .rod 1i' is coupled to a crank arm lh loosely mounted upon the shaft 11 alongside the crank arm-- 16, as liest shown in Fig. 4. A latch'19 pivoted upon said crank arm 18 normally engages a stud 20 on said crank arm 16' as there shown so that the two crank arms'will operate as one. Manifestly when the rock shaft 11 and its crank arm 16 are rotated in a counter-dockwise direction during the forward pull of the operating` handle of the machine, the crank arm 1S will be carried along by reason of the stud 20 being interlocked with the latch 19. and the spring vI3 will be stretched as usual. At the same time this latching arrangement provides for reiicving thc handle of the load of this spring whenever desired.

lau' thc reduction of load` takes the form ,of a key oufinger-piece 21 conveniently loi he manipulating means for accomplish leeches cated at the'left of the keyboard and oarn diate portion'a link 23 extending back to aA point above the rock'shaft 11 where it is coupled ltol an arm 24 secured to and depending from another ,rock shaft 25. At a point somewhat forward of its connection with said 4crank arm 24 this link has an offset arm 26 ofangular form, the down wardly extending portion of which- .has a stud 27 occupying an arc-shaped" slot 28 'in an extended portion of the latch 19. Under normal conditions this slot is concentric with the rock shaft 11 so that in oscillation of the latter accompanied by thecrank arm 18 the latch Awill not be affected and the interlock'between that crank -arm and-the crank 'arm' 16 will be maintainedf Normallythe lever 22 is forward as' illustrated in Figs. 1 and Ll. Then thrown rearward to the position illustrated in Fig. B ,said lever, through the medium ofthe link 2,3 and its angular branch 26' and stud 27, will rock the latch 19 on itspivot and disenga'ge the same from the stud 20, as lillustrated in Fig. 3. This obviously disconnects the spring 13 from the rock shaft 11 and consequently relieves the operating handle of that portion of the load represented'by the power of said spring. b

'Referring next to the matter of further relieving the load by eliminating the resistance odered by the dashpot governor, nu-4 meral 3() designates the dashpot cylinder and 31 the piston rod which is-coupledto the ear 32 of a reciprocating plate 33 located alongside one of the frame plates 34 of the printing section of the machine and slotted to embrace a stud 35 thereon. The dashpot cylinder is pivotally -supported at its lower cnd -as usual and the plate33 besides being longitudinally movable for reciprocating the piston is also pivotally movable about the stud 35 and to such-extent as to prov-ide for uncoupling it from the operating handlc. The rock shaft 11 is operatively conne'ted with another rock shaft 36 through familiar means including a link 3T and there issecured to the rock shaft 36 a cam plate 38 which is also 'a familiar element of the inachine, its main function being to' force rearward the restoring bail 40 which returns the i hars or strips 5 to normal rearward position.

This cam plate is the particular elementof.

the driving' or actuating means to which the dashpot is coupled. ordinarily in a permanent manner. F`or the purposes of the present invention vthe coupling is a separable one. Thus the dashpot operating plate 33 is notched as shown at 41 to embrace' a stud 42cm the said cam plate 38, as best shown in Fig. 4. n

TheA connections for shifting the said rot dashpot plate 33 to disconnect it from the cam plate 38 by the act of throwing rearward the key 21, are of the following de.-

scription: It'will be recalled that thelink' 23 which runs rearward fromthe key' levershaped link 45 which extends 'alongside the` lower rear portion of the dashpot plate 33 and carries a stud 46 occupying a notch 33a in the lowerend of said plate. This stud 46 is guided in a slot '47 of the aforesaid frame plate 34. lt will now be seen that the' rocking of the shaft 25, as-efected by throwing rearward the key 21, results vin pulling rearward said link 45 and thereby swinging the dashpot plate 33 in-a counter-clockwise directon around thestud35. In this manner the notch 41 of said plate 33 is carried away from the stud 42 of the cam plate 38 so that when the latter rocks counter-clockwise dur.- ing the forward stroke of the operating han dle it has no effect upon said dashpot plate. Saidstud 42 then simply rides along an under edge of the plate which under such conditions is concentric with the rock shaft 36, as illustrated in Fig. 3, where Ythe key 21 is rearward and the operating handle has been drawn forward. It will be clear, therefore,

that the load represented by the resistance of the fluid in the dashpot is removed.

Referring nextv to the matterA of discon 'necting the type-carriers from the registering mechanism, the numeral 50 designates 'the type-carriers which are ot the familiar form and hung up'on the rock-shaft 51` to which the restoring bail 40 is fastened. Said .type-car 1iers do not have the usual depending arms coupled permanently to the slide bars or strips 5 but there is separately mounted upon said rock shaft 51 alongside the type-carriers, -a series of lbell-crank levers 52, the depending .arms of which are coupled to said slide bars. Forwardly .extending arms of said bell-cranks are separably coupled tothe respective type-carriers, as best shown in Figs. 3 and 4. The bell-crank arm has a stud 53 and the associated type-carrier has a latch 54. The latter is pivoted to the type-carrier and notched atfits upper end toembrace the said stud and when embracinglthe same, shown in Fig. 4, the type-carrier and bell-crank obviously operate as one.

rlhe connections for displacing all of these latches and so uncoupling the type-carriers from the several vbellcr:f1nl:s, as a result of the throwing rearward of the key 21, are of the following description: The aforesaid rock shat't25 has a third crank arm 55 and a curved link is coupled thereto and ein -when the operating handle rf' tends forward., A similar link 57 is coupled to the before-mentioned crank-arm 44, and these two links' carry between them at their forward ends-a cross rod 58 which is guided in slots of the aforesaid frame plate 34 and the companion plate 34a'. The several latches 54 have downward andv rearward extensions 'with open slots and they embrace the said crossv rod 58. These slots and the rearward extensions of the lower sides thereof are normally concentric with the rock shaft 5l s0 that .when the type-carriers swing about the latter the latches willrbe unaffected by 'the bail cross rod 5S and the type-carriers will therefore remain coupled to the bellcrank levers 52. The considerable extension of the lowersides of the slots is for the pun poseo-t positively keeping the latches interlocked with the studs of the bell-cranks in whatever position the type-carriers ma.7 be. rIhe throwing rearward of the key 21 and consequent rocking of the shaft results in drawing the bailcross rod 53 rearward and thereby swinging all of the latf-hes upon their pivots and disconnecting them from the several studs 53, illustrated in Fig. 3. Then manifestly the forward movement of slide bars or strips 5 will be accompanied merely by clockwise movement 'of the bell-cranks 52 while the type-carriers remain at normal. As in all machines of this 'type the printing hammers are not tripped unless one or more type-carriers more out of normal position. Consequently no printing action will occur at all-so long as the key 21 occupies its rearward position.

Referringnent to the line-spacing mechanismpthis includesthe familiar oscillating arm 60 which is operatively connected with the rock shaft/ 11 and ordinarily acts upon a stud 61 of an arm'62 through which a square-sided rockerod 53 slides, the latter carrying at its left-hand end the line-space pawl 64. A spring 65pulls the arm 62 for ward but is normally restrained by engagement of the stud 61 with the end of the Aoperating arm 60. l/Vhen the handle is pulled that arm swings forward and down ward and is followed up by the arm 62 and the line-space pawl is retrac and then mal the said arni 6G acts upon me stud v51 and effects line-spacing.

The means for disabling the line-space mechanism as a result of throwing rearwardthe key 21 simply comprises a finger 67 secured to the rock shaft 25 which finger 'swings under the laterally turned portion .of the arm 62 to which the spring (S5 is attached. Thisv is clearly illustrated in Fig.

.3 and it will be obvious that when the linger has been so located 'the arm 62 cannot follow up the arm 60 when the latter swings forward and consequently there will be no line-space action. much of the power l of the main springs whichordinarily serves I isnot called upon to retract the printing .to effect the line-spacing is then not called upon and soit is entirely practicable to reduce that power to the extent of disconnecting one of the springs inthe manner before described, spring powerbeingneither re" quired to overcome' the resistance of the lfluid in the 'dashpot nor that of line-space elements, besides which such spring power I .plate 38 and the companion cam-plate.

. so they miss the latches.

,The hammers are engaged as usual by restraining latches .7 6 and there are latch-tripping pawls 74- in a swinging bail 75, and type carriers at normal hold up the pawlsl This is the familiar arran ement in this particular type of machine, t e Jform of the under edges of the type carriers being such that at normal and also when advanced only one step, they restrain the pawls 74 by engagement with the rear ends thereof, whereas when any type carrier is further advanced the asso-l ciated pawl is permitted to swing counterclockwise to engage the associated latch 76. As before. explained the setting of the key 21 disconnects the type carriers from their levers so that they do remain at normal.

At the conclusion of repeated operations i of the machine withthe key 21 set, that key' will be thrown ,forward to restore the machine to normal position, and then the producth or quotient maybe printed by operating the machine with the total or subtotal key depressed.

In order to somewhat further safeguard the mechanism and insuresmooth operation without loose play or rattle of uncoupled parts, I form the dashpot operating plate 33 with an extended arcuate edge 33h on the upper side of its lower rear portion, and just forward of this edge I form said plate with a notch 33, I secure a stud 34C in the frame plate 34 for cooperation with Said arcuate edge and said notch. Under normal conditions reciprocation of the plate 33 causes its said arcuate edge .to ride along the underside of the said studand this insures against any displacement of the plate -which might'otherwise cause its notch 33a to get out of registry with the stud 4,6. llhen the plate 33 is swung upward and` rearward as an incident to the pushing back of the key 21 the aforesaid notch 33 will be, caused to embrace the said stud 34, aS shown in Fig. 3, and the 4engagement between the stud and the lower side of the notch will thenA prevent playof the plate handle pull.

Leeacee which might otherwise take place as perpiston rod 31 of the dashpot between sliding col-lars thereon, as in the familiar construction.

Referring next to the modified construction. illustrated by Figs. 6 and 7, this pertains more especially .to the matter of reducing or limiting spring resistance to the In this modified construction there is not theI disconnection of.y a power spring asin the first described. construction but the tension of the spring is lessened' or removed altogether as an incident t0 the'setting of a special key. In this modified construction the said special key V2l and lever 22 upon which itis mounted are located at the right instead of at the left of the keyboard and of course the link 23 is correspondingly located. It may be assumed that only the power spring 12 is employed vin this construction, said spring heilig likewise located at the right-hand side ofthe machine. It is coupled as usual and as before described, permanently to the rock shaft 1l at the rear of the machine, and inasmuch as there is in this modified construction no un'- coupling of any power spring the said link 23 docs not have the offset arm 26 of the previously described construction nor any's'ubstitute for that. The link simplyconnects, as in the previously described construction, with the depending crank arm 24 of the upper rock shaft 25, which crank arm is shifted over -to the right-hand portion of said rock shaft to correspond with the location of the link. The arrangement for reducing the spring resistance to handle pull comprises a lever 100 pivoted 'under the keyboard'and to which lever the forward.end of the spring l2 is coupled; and a link 101 connecting the said lever to the handle lever I 22. The latter is capable of being flexed laterally and the keyboard panel 102 (which is part of the remvable casing of the machine) is formed not only with a slot 108 in which the lever 22 may work'back and forth, but also with notches 104L so 'that the said lever may be locked in its two positions of adjustment, which expedient is manifestly called for in view of the fact that the lever is connected to the power spring;l

Under. normal conditions the lever is for-` ward and locked in the front notch as shown R 'in Figs. 6 and 7, and consequently the lever 100 is held forward and the'spring12 under tension. 1When. the handle lever is disengaged 'from the front notch and is thrown separable coupling betweeri one ep ,meeting the tivo arms, and
