Application filed June. as, 1205. Serial No. 567,347.

To all whom it mayconcern:

Beit known that LFMN A. Yo UNo,

chines and more especially to tabulating mechanism for such machines. I

My invention has for its principal object to provide an improved denominational tabulator mechanism. a

"To the above and other ends that-will appear hereinafter, my invention. consists in certain features of construction and combinations and arrangements of parts which In the accompanying drawings, Figure will be fully set forth herein and particularlypointed out in the claims.

l is a right-hand side elevation of a typewriting machine having my invention em bodied therein, different parts being shown mechanism. is applicable to other styles of typewrit'ing machines.

The mainframe of the machine shown 1n the drawings, comprises a base portion having' side plates 1, which are connected together at their rear ends by a back plate 2 and a shelf 3. Said side plates 1 are also connected together just back of the keyboard by a transverse frame bar4, and intermediate said frame bar and the shelf 3, said side plates are also connected by a transverse frame b. .-.r'5. Posts 6 rising from the base portion of the frame support atop plate 7. Two posts or brackets 8, rising from said top plate, support an upper ra1l 9 grooved on its lower face and a lower rall 1O grooved on its upper face, the grooves 1 n said rails constituting race ways for antifriction balls or rollers 11 which run in cooperatin'g race-ways in the. rails of a carriage 12 which supports a platen Said carriage is drawn across the machine by :a

spring drum (not shown) and its motion is controlled by a feed mechanism comprising a feed rack bar 14., which is mounted on arms 15 which are pivoted at their forward ends in the carriage by means of short rock shafts, on the outer ends of which are mounted release keys 16. The arms 15 are engaged by compression springs 17 which i tend to press the rack bar 14L downward into engagement-with a feed pinion 18 which is mounted on the forward end of a shaft that is journaled in a bracket or housing 19. Said shaft at its rear end carries an escapement wheel 20 that is controlled by feed dogs 21 mounted on an arm 22 that is carried by'a rock shaft23, that is pivoted at its ends in a bracket 24 depending from the top plate 7 The arm 22 and rock shaft 23 jconstltute parts of a dog rocker whichalso comprises a forwardly extending arm 25 that is connected by a link 26 with an arm 27 connected with a universal bar 28. Said universal bar and arm form parts of a rock frame which also includes a rock shaft 29 pivoted at its ends in the side plates 1. The

universal bar 28 lies beneath a series of character key levers 30 having character keys 31 mounted on their forward ends and pivoted at their rear ends on a pivot plate 32 mounted beneath the shelf 3. The key levers 30 are provided with returning springs 33. Sub-levers 34: are pivoted to the key levers at 35 and their. slotted lower ends "engage an abutment or frame rod 36.. The

upper ends of the sub-levers are connected by links 37 with front-strike type bars 38 which are pivotally mounted in any suitable manner in a segment 39. The free ends of the type bars 38 normally rest against a segmental cushion or pad 10 which is supported bythe segment'39 by means of rods 41. The construction is such that when any character key 31 is depressed the corre' spondingsub-lever 34 is, moved toward the rear of the machine and the type bar 38 is moved about its pivot to cause one of the types on the end thereof to strike against the front face of the platen 13. p

The mechanism above referred to is old and well-known and so far as my invention is concerned it may be of any suitable con- .struction.

My tabulator mechanism includes a tabulator bar 42 mounted on brackets 43 project- .ing toward the rear of the carriage 12 to which they are secured by screws 44. The

tabulator bar has the usual slots 45 formed in its front and rear faces a letter space distance apart. In. order not to interfere with 1. One or more column stops 46 are adapted to be mounted on the tabulator bar 45..

this tabulator bar and the stops mounted thereon, the brackets 8 which support the carriage rails are arched toward the rear of the'machine in the manner shown in Fig.

These column stops are, or may be, of ordinary construction, that is to say, they are of inverted U-shape and are formed with web portions adapted to enter the slots 45. Any of said stops may be placed'in any of the said slots so that'said stops are adjustable lengthwise of the tabulator bar to arrest the carriage at any desired letter space position.

The denomination -stops consist of the upper ends 47 of a series of levers 48 which are pivoted at their lower ends on a stationary rod-49 just above the shelf 3. The levers 48 are levers of the. third order. The levers 48 are mounted in a frame that is detachably secured to the main frame of the typewriter.

Said frame comprises two upright side pieces 50 which are connected together at their lower ends by a cross-bar 51 and at their up.- per endsby a plate 52 secured, as by screws, to the front edges of the uprights 50 just to the rear of the path of the column stops 46.

Each of the levers 48 is curved at its upper end toward the front of the machine and the forward ends of said levers play inand are guided by slots in the plate 52, said slots being spaced a letter space distance apart.

Said upright frame pieces 50 are also 0011- nected together at their lower ends by the rod 49 which passes through said frame pieces and is secured in position by set screws 53, threaded through said uprights and engaging said rod. The uprights 50 are each formed with a bracket 54 projecting over the top plate 7 to which said brackets are secured by screws In order to connect the lower ends of said uprights with the shelf 3, the projecting ends of the rod 49 lie in vertical slots in cars 56 projecting up-' ward from a base plate 57 which lies on theshelf 3 and is secured thereto by screws 58. This form of connection with the shelf 3 is adapted only to'prevent motion of the framein the slots in the ears 5 6 preventsmotidiii in any other direction. 1

The levers 48 are guided near their lower ends by slots in a comb plate 59 which secured to the crossbar 51 and, which pro- 70 jects toward the front of-the machine, as

shown in Fig. 1. Each of said levers 48 is; provided with a returning spring 60 (Fig.-

1). Thesereturning springs are coiled compressionsprings seated inholes in a frame, piece 61 which is secured to the forward faces of the upright frame pieces 50 fbyf screws 62 (Fig. 3). Each of said presses at its forward end against a sore.

' 63 threaded into the forward'end of the hole,.-

and the tension ofsaid spring may be regulated by adjusting said screw. The rear end of each spring presses against a pin 64, the. rear end of which engagesthe lever 48. If desired, a casing for the rear side of the tabulator stop mechanism mayjbe provided, consistingmf a plate 65 secured to the rear faces of the uprights 5G by screws 66. The upper ends of the levers 48 are spaced a let tcr spacedistance apart, but for convenience in operating said levers I prefer to spread their lower ends to a wider distance, .as shown in Figs. 2 and 3. V.

The denominational stops are operated'b a series of denominational tabul'ator keys 6 arranged in a tier or bank in thekeyboard, of the machine back of the" character keys. 31. Said keys 67 are mounted on the forward ends of a series of tabulator key levers 68 which are pivoted at their rear ends on a fixed rod 69 which is-mounted in a stationary detachable frame 70. The frame 70 is. four sided, having a reartransverse bar" mounted on the crossbar '5' of the mainframe to whichit is securedby a screw .711. Said frame has a forward transverse bar-72 lying just back of the 'barA ofthe main frame, and said transverse frame barsare' connected together by side bars as shown. Two ears or brackets 73', each, as shown-inthe present instance, being somewhat in the nature of an extension of-one of the side bars of the frame, lie on top of the transverse bar a 4 ofthe main frame, to which-bar said ears] are secured by screws T4. The forward ends its of the key levers 68 are guided by'a slotted"- plate 7 5 which issecured to the front of theears 3 by screws 76. The upper edge of the plate 75 bent over and 'supportsa pad"??- for arrestlng .the keys in normal-position.

The keys are guided near their rear ends by slots in a comb plate 78 which is se'cured'b'yv screws 79 to theforward-faces gof'brackets 80 rising from the side bars'of the frame ?0. The comb plate 75 is supported near its mi d-P dle' by a bracket 81 projecting from the cross-bar 72.

The pivot rod 69 is mounted the lower part of the frame 70 as shown iii-Fig.1. In

the present instance said baris below the curved or angular form shdwn'in Fig. 1'

' tending link 83, the rear end of which is pivlevel of the upper surfaces of the. frame bars 4 and 5. Each of the key levers 68 is of the 7 thatfis to say, each of said levers extends upward from the rod 69, thence forward through thecomb plate 78. The construction is such that when one of the keys 67 is depressed, that portion of the lever (SS that stands above the rod 69 moves toward the front of the machine. Each of said levers has pivoted thereto at 82 at this forwardly moving portion thereof, a rearwardly ex= oted at Sate one of the levers -l8l The-pivots 84 are some distance above the pivot rod 49 and in order to bring the links 83 to theproper elevation, said links are curved upwardly and rearwardly in the manner shown in Fig. 1. lVhen one of the keys 67 is depressed, the link 83 is drawn toward the front of the machine and the corresponding lever 4-8 is rocked toward the front of the machine about its pivot 49, moving the stop end 47 thereof into the path of the column stop 46. When the key is released, the parts are restored to normal position by the spring 60, the motion of the parts being arrested by the key lever 68 coming in con.-

tact with the pad 77.

It will be noted that for the key action of my tabulating device I utilize the space above the characterkey levers and belowthe typebars. The links 83 extending toward the back ofthe machine pass between the upstanding sub-levers 34 in the manner shown in Fig. 3. As the tier of keys 67 is necessarily much wider than the back of denomination stops 47, the key levers 68 ,back of the comb plate 75 are bent toward the middle of'the machine, thus fanning in, so that the pivots of said levers are'closer together than the free ends thereof. The

links 88 also converge, being closer togetherwhere they are connected with the levers 48 than where they are connected with the key levers 68; and as is best pointed out above, the levers 48 also converge toward their upper ends. This disparity in the respective widths of the series of stops and the series of keys-that control them is thus distributed between the stop levers 48, the

actuating links 83 and the key levers 68. Each of the links 83 where it passes between two of the sub-levers 34 may be bentas shown in F in. 3, so that that particular part of the link does not depart so much from a straight fore: and aft line as to interfere with the operation of said sublevers.

In order to release the carriage, when any tabulator keyis depressed a universal bar 85 is provided lyingbeneath the series of key levers 68.' Said universal bar is carried at its ends by arms 86 which are pivoted on the pivot rod 69. An arm 87, projects to- Ward the rear of the machine from the midrack dle of the universal bar 85 and the rearend of said arm 87 has a pin that projects'into the slot in the lower end of a link 88,, the upper end of which is pivoted at-M89 to a lever 90, one end ofwhich is pivotedtat 91 to a bracket 92 depending from the -top plate'T. The free end of said lever QO-ha's pivoted thereto the stem of, a rack .liften93 1 that projects through iavsuitable' opening L in the top plate 7. The upper end otsai'tl rack lifter is forked to embrace the reduced forward end of the housing 19,0f the res capement wheel shaft. Each of-theforks of the rack litter 93 is bent toward the front of the machine and lies beneath th '4. The construction is such that when the universal bar 85 1s depresse'thhy any of the key levers 68, the feed rack is lifted oil of the pinion 1S and the carriage is then released from its escapementmechanism. lVhen the tabulator key is released the arm'87 and the rack lifter drop by gravity to their normal position in which the arm 87 rests on the rear cross-bar of the I 'frame 70.

national stop levers.

It will be understood of course that not only may the tabulator mechanism tli iil whole be inserted in-previously made inachines in the hands of customers but it may, if desired, be incorporated in theyma'chine in the first instance at thetime of, its building. I
