TYPE-WRITING MACHINE Specification of Letters Patent.

Patented May 4, 1909.

Application filed November 21, 1905. Serial No. 288,440.

'Writing Machines, of which the following is a specification.

My invention relates to tabulating mechi anisms for typewri-ting machines and has-for its main object to provide. a. simple and effeetive tabulating mechanism, wherein the actuation of a key will interpose a stop mounted on the frame of themachine in the path of the carriage and will efiect the reease of the latter so that it may be arrested at predetermined points for column or tabulat-mg Work. To the-above and other ends,- the invention consists in the features of constru.ction,'combinations of devices and ar-' rangements of parts hereinafter fully described and claims.

In the accompanying drawings, Figure 1 is a vertical, longitudinal sectional view of so much of a-typewriting machine as is necessary to clearly illustrate my invention, parts of the machine being omitted. Fig. 2 is a rear' elevation of the machine, certain of the parts being omitted. F ig. 3 is an enlarged fragmentary rear elevation, partly in section, of the stop rack bar and its supports. is an enlarged sectional side view showing the platen, platen carriage and certain of the parts of the tabulating' mechanism. Fig. is an enlarged fragmentary top plan 'view showing the tabulating stop on the frame of the machine and the stop rack bar, one of particularly pointed out in the the stops being shown on said rack bar.

I have shown my invention as apyplied to a machine generallyresembling the Jlonarch "typewriter, but it is to be understood that "said invention may be adapted to other forms of writing machines.

Referring more especially to Figs. 1 and 2, 1- indicates the base of the machine supporting corner posts 2, which, in turn sustain a top late 3. Key levers 4 are fulcrumed on a in crum plate 5 and each key lever is provided with a restoring spring 6. Iivoted at 7 to each key lever is a sub-lever 8, the lower "portion whereof is slotted to cooperate with afixed abutment 9 and the uppcrend whereof is connected by a connecting l nk 10 with a type bar. 11 pivotally mounted in a hanger Fig. 4.

'12, said hanger being secured by a screw 13 to a segmental type bar support 14 and being one of a series of hangers similarly secured to said support in an arc of a circle. The free ends of the type bars are normally supported by a segmental type rest 15 and said i type bars are adapted to cooperate w th the i front face of a cylindrical rotary platen 16 which is mounted ina platen carnage, said platen carriage comprising side bars 17 and disposed grooved rails 18 connected' near their-ends by web portions 19. Antifriction balls 20 are seated in the grooves in carriage I rails 18 and'cooperate with oppositely-disi posed grooved guide rails 21 and 22, said gulde ralls being secured by screws 23 to machine. A feed rack 25 is secured at its ends to arms 26 which are pivoted at 27 in the side bars 17 of the carriage and said feed rack is normally maintained bygrayity and a rack spring (not shown) in mesh with a feed pinion 28 fixed at the forward end ofa short shaft 29, said shaft being journaled'in a bracket 30 fixed to thetop plate. Operatively connected with the rear-send of the shaft 29 is an escapement wheel 31 and adapted to co-act with said escapement wheel are feed dogs 32 mounted. at the top of a pivoted dog rocker 33 which dog: rocker Eis provided with a.horizontally disposed arm 34. A link 35 connects the dog rocker arm 34 with a universal bar frame 36 pivoted at 37 in the base of the machine andcarrying a universal bar 38 which extends from side to side ofthe machine beneath the series of and is adapted to be depressed by said levers during printing and spacing operations. The carriage is provided with a depending pin or lug 39 towhich is secured one end of a rear bar which latter comprises oppositely brackets 24 fixed to the top plate of the key lovers and thespacinglovcrs (not shown) 7 a band or strap 40, the other end whereof is l released from its escapement mechanism and may be drawn freely leftwardunder the influence of said spring drum.

As appears most clearly in Figs. 3 and 5, 5 my tabulator mechanism comprises a rack bar or rod 42 formed on its front and rear sides with slots 42 a letter space distance apart and mounted in cars 44 projecting rearwardl r from angled brackets 44, said brackets eing secured fixedly, to the web portions 19 of the carriage by headed screws 45. The top of the rack bar 42 is preferably provided with a scale corresponding with the carriage scale and one or more column steps 43 may be mounted on said bars, thestops being bifurcated to engage the notches or serrations 42 and beingprovided with contact portions 43". As viewed from the rear of the machine the left endof the rack bar 42 is reduced as indicated at 46 (Fig. 3), the

reduced portion forming a shoulder 47 with the body of the rod;- A headed bushing 48 surrounds the reduced portion 46, the bushing being externally threaded and being recelved in a threaded'opening in the. left-hand bracket ear 44. A'Iocking nut 4U'serves to secure the bushing in a fixed position afterit has been properly adjusted. The inner end of the bushing is formed with a hole 50 which receives a coiled spring 51, the inner end of said spring abutting against the shoulder 47 on the rack bar 42. A headed screw 52 is received in a threaded-opening in the end of the reduced portion 46, the head of said screw being normally maintained seated in a countersink in the end of the bushing 48 b the'pressure of the coiled spring 51 whic 1 normally tends to press the rack bar 42 in printing direction. .The other end of the rack bar 42 is provided with a groove 53 and engaging said groove is a key 54 which is seated'in a slot in the bearing opening in the bracket 44. The construction is such that the rack bar 42 is ca )able of longitudinal movement but is held from rotary -move- -ment by the ton ue and groove connection provided by thekey 54 and groove 53. As will be noted from an inspection of Figs. 1 and 4, the bracket ears 44 reject rearwardly so that the rack bar 42 is ield some distance from the rear of the carriage. The supporting brackets 24 of the guide rails 21 and 22 are curved rearward ly a sufficient amount to permit the free and unobstructed move- 55 ment from side to side of the machine of the bar 42 and its bearing cars 44, and also of the column stops 43.

As best shown in Fig.5 a bracket 55 is secured to the rear face of the upper guide rail 21 by headed screws 56. The front face of the bracket 55 is proyidcd with a projecting portion 55 which entersa slot or depression 57 in the rear face of the guide rail 21, the construction being such that the positioned. Ears 58 project rearwardly from the bracket and said ears are perforated to receive a short shaft 59 upon which is pivotaliy mounted a tabulatin stop designated as a whole by the numera l 60 and comprising a hub portion 61, a rearwardly and downwardly extending stop ortion or arm 62 and a forwardly extencing arm 63. The stop )ortion 62 is provided with-a reinforcing ril face by a screw 65 is a hardened steel plate 66, the head of the screw 65 being flush with the face of the plate 66'which latter. is per forated to receive the shaft 59. This con; struction enables the stop member 60 to be made of cast metal. One end of-the top portion of the stop member is reduced as indicated at '67, said reduced portion abut 64 and secured to its ting one of the ears 5S and being surrounded from endwise movement by the abutting The forward end of the" bracket cars 58. arm 63 is provided with a lug K3 aiid the spring 68 tends to maintain sai lug in contact with the top of the bracket 55. The under edge of the arm 63 is formed with a notch 63 (Fig. 5).

Engaging the notch 63 in the stop arm 63 is a stop lifter 69, the lower part of which is bifurcated, the bifurcated portions being secured by screws 70 to the arms of a bifurcated rack-lifter 71. The arms oi the rack lifter are disposed one at each side of the shaft '29, the journal or bracket 30 being cut away to guide and support said rack litter. The bifurcations of the rack lifter are bent forward horizontally, forming lifting shoes f 72 which stand norinally beneath and. out of en agement with the feed rack 25.. The stop lifter 69 18 an extension from the rack litter and the two may if preferred be formed from a single piece of metal instead oi two pieces rigidly iastened together. The lower end of the rack litter is ivotally connected at 73 with a lever 74 in crumedat 75 in a lug 76 depending from the top plate of the machine and provided with a restoring spring 77. The other end of the lever 74 is pivotally connected at 78 with the upper end of a vertically disposed link 79, the lower end whereof is pivotafly connected at 80 with a tabulating key lever 81 pivoted at 82 in the base of the machine and provided at itsiorward end with a tnbulating key 83 which, it will be noted from an inspection of Fig. 1, is in the regular keyboard of the machine.

(55 bracket 55 is thereby properly centered or I In assembling the parts the rack bar 412 is properly adjusted by means of the threaded I operations may be performed and thereafter ushing 48. It will be understood that for any desired form of tabular work the necessary number of stops 43 are placed in the proper positions on said rack bar. '5 he nor mal position of the parts is best seen in Figs. 1 and 2. lYhen it is desired to operate the tabulating mechanism the tabulating key 83 is depressed, thereby, through. the i 10 link 79, operating the lever 74 and raising the rack lifter 71 and the stop lifter 69.;

is the rack litter is raised the lifting shoes 72 engage with the feed rack '25, swinging the latter upward about its pivots 27 and out ]5 of engagement with the feed pinion 28,

thereby releasing the carriage and permittin it to be drawn freely left-ward under the in uence of the spring drum 41. At the same time the stop lifter 69 swings the stop arm 63 upward about its pivot 59 against the pressure of the spring 68,. and swings the stop arm 62 downwardly about the pivot 59 until the working face 66 is in the path of the .contact portions 43 of the adjustable stops 43. The parts will now be in the position shown in Fig. 4. ihe carriage will move freely or jump leftward until the first stop 43 to the right of the working face 66 contacts with the latter, ac thereby preventing the further longitudinal n ovcment of the rack bar 42. The carriage, however, will continue to move in printing direction, compressing the spring 51, until the inner end of the bushing 48 contacts BSJwith the shoulder 47 of the rack bar 42.

The tabulating key 83 may then-be reeascd, the parts being restored to normal position under the influence of gravity and the spring of tlie rack 25, the stop spring 8 and the spring 77. As soon as the contact face (36 of the rotary tabulating stop 60 has swung upwardly farenough to disengage from the cooperating carriage stop 4-3 the rack bar 42 will be moved leftward by the compressed 45 spring 51 until the head of the screw 52 engages with the bottom of the. countersink in the bushing 48. rack bar 42 has a slight longitudinal movement independent of the platen carriage, the

amount of this movement being limited by stops and being equal to the space shown in l ig. 3 between the shoulder 47 and the inner end of the bushing 48. This slight independent movement of the rack bar 4-2 55 carries the co-acting stop 43 to the left of the contact arm 62', the construction being such as to provide considerable clearance between the co-acting tabulating stops and not to necessitate that said stops should (so be made so thin as to render them too weak for practical work. This is especially advantageous in view of the fact that the stop member (it) is a casting. zfhen the parts have been restored to normal position 65 as above explained, the desired printing lt will be seen that tho' the tabulating devices may be operated as before'to bring the carriage to the next desired columnar position.

It will be seen that I provide an efficient tabulating n-echanism of few parts and one which may be readily assembled in the n "nine. 1 do not, however, desire to be limited to the precise. construction shown and it will be understood that various changes may be made in the construction. and arrangement of different parts within the scope of my invention. 7
