Specification of Letters Patent.

Patented May 10, 1910.

Application filed February 11, 1908. Serial No. 415,373.

To all 'whom itmayvconcem:

Be it known that I, OSCAR lVooDwARD, States, and resident of of New Jersey, have invented certain new and useful Improvement-s in 'Iype-VVriting` Machines, of which the following is a specichines and more particularly to-carriage feed mechanism, and the main obiect of saidv 1nventi'on is to provide simple and efficient mechanism of the character specified.

To the above and other ends which will hereinafter appear, my invention consists of the features of construction, arrangements of parts and combinations of de Yices to -b'e setforth in the following specification and particularly Apointed out in the .appended claims. V

In the accompanying'drawings, Figure 1 is a central vertical front to rear sectional view of a typewriting machine vembodying my invention, somev of .the parts being omitted. Fig. 2 is a horizontal sectional view of thesame with. parts broken away, the section being taken just 'above the key levers. Fig.-3 isa detail fragmentary plan view, partly in section, of the carriage and 'some of the associated parts. Fig. 4 is a front elevation of the same with parts broken awair and parts in section. Fig. 5 is an enla-rgeddetail front elevation with parts in section-of portions o f the escapement mechanism. Fig. 'Gis an enlarged detail fragmentary front elevation with parts in section showing the pivotal connection between one end of the feed rack and the carriage. F ig. 7 isa-n enlarged detail transverse sectionalview taken through' the escapenient wheel shaft on the line no in Fig. 5 and looking in the direction of the arrow at said line. Fig. 8 is 4a like view of the same, the section being taken on the line g/ 'z/ of Fig. 5 and looking in the direction of the arrow at said l1ne. Fig. 0 is an enlarged fragmentary side elevation, partlyv -Arthur lV., Smith 22nd, 1907, and is of the same general char# acteras that disclosed in the application of Serial No. 260,441. v l

The frame of the machine compriset side plates 1, a rear cross-plate 2, a front cross plate 3 and a top plate 4.. Key levers 5 are pivoted on a pivot rod 6 connected to rear' wardly extending arms 7 ofan auxiliary frame 8. The forward end of each key lever is provided with a linger key 9. A pull link 10 is connected at its lower end to a key sied May 15th, i905,-

lever 5, the upper endof the'link being conv nected to a forwardly projecting arm of an associated bell crank sub-level' 11 pivoted at 12 to a hanger 13 secured by a nut 14' to a segment 1'5 which forms part of the auxiliary frame 8. The upwardly extending 'arm of each 'sub-lever 11 is pivotally connected to the forward end of a pull link y16,

the rear end of said link being connected to a type bar driver 17. -Each driver `is pivoted at 18 to a hanger 19 secured by 'screws 20 to a segment 21 which forms part of the auxiliary frame 8. Each driver 17 is pivoted at-.22 to a type bar 23. Each typebar` is pivoted at its forward end to a guide link 24, the system of guide links being pivoted on a pivot wire 25 receiyed in a groove in a segment 26 forming -Lai-t of the auxiliary frame 8, each guide working in a radial slot 27 in said. segment' 2G. The types 28 at the rear ends of the typel bars normally rest against` an inking pad 20 secured to the main frame'of the machine. of the finger key 9 causes the lower case type on the associated type bar to follow platen 30.

A universal bar A comprises a strip 31 of leather or some such suitable material received in a sheet metal container or bar 31a substantially U -shaped in cross-section.

Theleather strip is secured in the container' by shouldered rivets 31" which pass through the path of the dotted line a in Fig. 1 and to impact. against the front face of a cylindrical t ds ' openings in the sides of the Vcontainer and in the leather stripv and the shoulder on each rivet bears against the inner face of one .of the sides of the container. The containerl 31a is riveted or otherwise secured at l32,1iear each end thereof to a rearwardly extending arm 33 preferably made of sheet metal and having an inwardly bent portion 34 near the rear end thereof.l This inwardly bent portion 34 of each arm is apertured at 34a (F ig. 1l) for the free passage ofthe stem of a headed screw 35' and also has an open slot 341 for the free passage therethrough of the stem of a headed screw 85E. These screws are received in tapped openings inarms .36

which lproject forwardly and -rearfrom a rock shaft 37. rllhe under ywardly side of the rock shaft is provided with downwardly extending projections 38 (Figs.v

9 and 10), each of which constitutes a fulcrum coperative with the associated inemy ber 34. From an' inspection of Fig. 9 it will i and `which is tightene be seen thatthe screws 35 and 35a which connect eachv Iof the arms 33 to the rock shaft are on y'opposite sides ofthe associated ful- Crum or projection 3S and that the loosening of one. of the screws and the tightening of the other eects an adjustment of the associated arm 33 relatively to the rock shaft9v the adjustment of the arfn up or down depending on which screv 1rocker in the same position the bar had before its removal. Theconstruct-ion thus -aff fords means for readily removing the universal bar and rye-connecting it'and for adjusting the arms 33 up or down around the fulcrums 38 and for effecting an up or down v to the adjustment of the universal bar 31 secured forward ends thereof, thereby adjusting the universal bar relatively to the key levers 5 without disturbing the escapement mechanism. The means also aord an individual adjustment of the universal bar at opposite ends thereof.

V The rock shaft 37' constitutes a dog rocker provided with a rearwardly projectirg'arm 39 which carries feed dogs 40. The ends of the rock shaft of ythe dog rocker are offwset as indicated at 37a '(Fig. 2) where they are apertured at41 (F l0) for the reception of pivots 42 each forming part of a screwI 43 received in a tapped opening in a side plate l of the machine at its base and proofy ` projects esmas jecting provided with the slot 44 for coperation with' a screw driver or other suitable tool to effect a longitudinal `adjustment of the pivot.` A lock nut 43a coperateswith each screw 4? to hold itin its adjusted position. One of the ai'msl33 of the universal bar'is .provided with a laterally projecting pin 45 of a contractile restoring by which one end spring 46 is connectedto said arm, the op posite end-of the spring receivinga nut 47 threaded exteriorly forcoperation with the convolute of the spring 46 and threaded interiorly for cooperation with 4the stem of a headed screw 4S which passes freely through an opening in a cross bar 50 secured -at its ends by screws-'51 tol forwardly projecting lugs '52 constituting holders for rubber feet 53 `of the machine. The head ofthe screw 48 is readily accessible to the operator from the front yof the inachine'and may be adjusted with a screw driver to vary the tension of the spring 46. The tension ofthe spring 46 is exerted to maintain the universal bar in the elevated position, as shown in Fig. l.

' Leversl 54 .are pivoted on. the pivot rod 6 near each side of the machine and are bent inwardly at their forward ends and then forward to provide feet 55 -apertured for the reception of screws 56 by which said levers are rigidly cnnected to a spacing key or bar 57. Eachy of the levers 54' is provided tothe outside of the base where it is i with a downwardly extending projection 58 n which co-acts with the universal bar. The return movement of the dog rocker to normal position is limited by ascrew stop 59 received in a tapped opening in across bar 6 0 connected at. its ends by screws 61 with lugs '62 which also constitute supports for rubber feet '63 of the machine. loclr nuty 64 coperates with the set screw 59 to mainl tain it in adjusted position. The nearwardly projecting arm 39 of the ldog rocker when in normalV position bears against the upper end of the screw, thus limiting Aits movement in one direction. vThe feed dogs 40 coperate with an escapement wheel 65, f

the hub 68 of which surrounds a sleeve 66 (see Fig. 5), said sleeve having a circumferential flange 67 at the lower.'Y end thereof againstwhich the lower end of the hub' 68 of the escapem'ent wheel bears. A. vertically disposedshaft 69 is'secured to the sleeve 66 by a pin 662L an 4end as at 70 for the reception of a pivot 7l formed on the upper end of a screw 7 2 received in a tapped opening in a lug 73 which rearwardly from the cross bar 60. The upper end of the shaft -69 is provided with a feed pinion 74 secured thereto by a pin 75 which passes through openings in the hub of the feed pinion and through the shaft.

The lower end of the hub on the feed inioii` bears against the upper end of a anged sleeve76 .in which the shaft 69'turns and is apertured at its lower 89 therein, the opposite end of the spring' -being secured to a l which surrounds the .shaft 69 and which is project froma carriage tr uck-98.

A said ratchet wheel extending upwardly. A

. through threaded openings in the sleeve and 'as xat 85 for coperation with a flattened the pawl to force ,80. The spring 88 surrounds the sleeve 83 101 to the carriage truck andbear at their Vlevers 95 and tend to force the. rack to the Below the sleeve 76 is a the shaft A69 by a pin 78. 79 is formed integral Wheel, the teeth 80 of bracket platea.

collar 77 secured to A ratchet Wheel with the escapement paWl 8,1 is pivotedA on a shouldered screw 82, threaded into an opening in a sleeve 83 Which surrounds. the shaft 69 and is secured thereto by screws84 (Fig. 7) -Which extend bear at their inner ends in recesses formed in the shaft 69,'thus locking the sleeve to rotate-With the shaft. The pawl 81 is segmental in shape andis flattened on one face face at one side of the sleeve. The terminal portionsof the `paWl are curved as shown in Fig. so that the engaging nose 86 may cooperate `with the teeth of the ratchet wheel. A" pin l87 projects upwardly froml the pawl to provide means by Which one end ofa contractile spring 88 may be secured to the engaging nose 86 thereof into engagement with the ratchet teeth and is received in 'a circumferentialgroove pin 90 Which projects from the sleeve. A cylindrical housing 91 surrounds' the pavvl and ratchet mechanism and extends inwardly to form a. huby 92 slotted at 69a to render the hub slightly resilient to eXert a binding or frictional engagementwith the shaft 69. When the housing 91 is in thej normal position it rests upon the upper edge ofthe sleeve 83 but may he movedl up along the shaft 69 to expose the paWl and ratchet mechanism.

` From an inspection of Figs 1 and l it Will be seen that the' feed pinion 74 coperates with 'the feed rack 93,I connected near its ends by screws 94 with threearm levers 95 pivoted at 96 vto depending lugs 97 which The forward .arm of each of these levers .is adapted to bear against a-set screw 99 carried by the truck in order .to limit the movement o'f the feed rack back to normal position.. Leaf springs 100 (Fig.4 3)are secured by screws free ends `on/a second setof arms 102 on. the

normal position Where it engages the feed pinion. The third set of arms on the levers 95 are those which areconnected to the feed rack. The leaf springs 100 each bears aga-inst a projection or fulcrum 103 (Fig-.4) and the screws 101 for each spring are situated on opposite sides of the fulcrum 103. By adjusting the screws 101 the pressure of the springs upon the arms 102can be nicelyY regulated and these means provi le fc-j individually adjusting the pressure of thcl comprises a.

, ringe is supported.

springs at each end of the pivoted rack.. The pivotal connection between the feed iadt and the truck is shown in F-3 and`4 'and is also shown in detail in Fig. 6. From these figures' it will bey seen that each pivot'96 pivot portion proper' which is received in the bearing-opening. in the sociated lever 95and a circumferential abutment or-collar 104 which bears'against the inner faceof the lever to prevent a longitudinal movement of the feed-rack and the levers95 connected therewith onthe pivotl bearings. Eachl pivot 96 is extended t'o form a threaded portlon 105 which isreceived in a tapped opening in the associated bearing lug 97 and is provided with a lock nut 106 by whichit may besecured in its adjusted position. By turning the screws 105 in their .bearing lugs 97, one out-and the other in, a longitudinal adjustment of the -feed rack may be'e'ected relatively to the truck.

Uponreference to F1gs. 1, 3 and 4, it will be seen thata release lever 107 is pivoted to.

the left-handv end plate -of the truck at 108. The release leverlis provided with a slot 109 through which 'a pin 110, projecting from the left-hand endplate-of the truck, extends. -l`heupper end ofthe release lever is provided with a. linger piece 111 and the 'lower end 112 of the 'release' lever engages a projection 113 on the feed rack in order to move the feed rack'rea'rwardly against the tension of its springs 100 when the finger piece 111 .is moved forwardly, thereby disengaging' the rack'from the feed pinion and .freeing the carriage from itsescapement mechanism.

A platen `frameill carries the platen 30 .and is connected .to the 'truck 98 by parallel links 115 soas to afford case shifting movements of the platen by suitable case shifting mechanism (not sh own). vThe truck is supported by antifrictionrollers 'or balls-116 which arere ceived in guide Ways 117 formed in the truck and oppositely disposed grooved rails relatively to the .truck 118 fixed to the frame ofthe machine. It

will be seen thatIv a spring drum 119, is mounted in bearings beneath the carri-age and that a cordor band 120 surrounds the drum and is secured thereto at oneend, the opposite end of the cord or band being secured at 121 (Figs. 3 and 4) tothe truck at the right-hand 'en d thereof and aboutV centrally of the carriage between the carriage rails 118. Referring particularly to Fig.

it will be seen that thepull'of th, spring drum on the carriage is exerted about mid- "Way of the carriage considered fore and aft of the machine and about midway between the. fixed guide rails 118 on which the car- The effect of this conpull on the carriage at a is most effective and so nection isto exert a point where the pull other yfeed dog into engagement therewith.

1When pressure is. released uponV the finger key the parts will be restored to their normal positiois and a feed movement of the escapement wheel will be effected through 4the pressure exerted by'the spring drum upon the truck, this pressure being transegvnitted through the feed rack 93, its actuatihg pinion 74, escapement wheel shaft 69,

paw...I`A 21.` and ratchet wheel 79. Then the carriage is moved from left to right to begin a new line of writing the shaft. 69 is rotated in the vopposite direction through the rack' 93 and pinion 74, the pawl 81 at' this time slidinf over the teeth 8O ofthe ratchet wheel. without affecting the escapement wheel. lt will be seen that the con struction is such that t-lie feed raclris situ'- ated' beneath the `carriage and Vabout mid way between the bearings for the carriage so that the pressure exerted by the. spring drum upon the carriage it transmitted to the feed pinion 74 in a manner in which it is most effective to actnate vthe escapeinent wheelwithout undue lateral strain being exerted'upon the carriage bearings. Furthermore, the construction of the universal bar and dog rocker is such that a direct actuation of the parts is effected byl the key levers, the feed dogs in turn acting directly upon the escapement wheel.

rllhe bracket 76al hereinbefore' referred to is secured by screws 122 (Figs. 1, 3 and 4) to across bar or bridge piece 123 extending transversely of the machine above the cross bar or bridge piece 60. The bridge piece 123 is'secured at its ends by screws 124; to inwardly projecting lugs 125 ony the machine frame. y substantial'- supports are lprovided for the bearings of the escapement shaft 69 and the parte carried thereby. The cross bar 123 is lilfcfavise apertured to receive the spring drum 119 that turns on a pivot 126 supported in lugs 127 extending downwardly from the cross bai- 123.
