Be it known that I, ARTHURW. SMITH, citizen of the United States, and resident of the borough of Manhattan, city of New York,

in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machineaof which the following 1s a specification.

M invention relates to carriage-retardin 1 mec anism 4for typewriting machines, an has for its object to pro-vide an impro* fl device of the class specified.

To the above and other ends the invention resides in the features of construction, combinations 'of devices and arrangements of parts hereinafter fully described and parthe claims.

-I have illustrated my invention as applied to a typewritingl machine generally resembling that commercially known as the No. 10 Yost typewriter, and in connection with a tabulating mechanism generally resembling that commonly known asthe Gorin tabulator. It is to be-understood, however, that my improvements may be readily'adapted lto other forms -of typewriting' machines and other styles of tabu ating devices.

Fig. 2 is a fragmentary lon itudiiral sectional view taken about centrally of the machine, parts being omitted. Fig. 3 is an enlarged detail sectional View of the escapement wheel and its bearing and of the clutch mechanism. Fig. 4 is an enlarged perspective View of one of the parts of the vclutch mechanism. Fig. 5 is a fragmentary Fig. -9 is .en enlarged 'perspective view of a partsy with the supporting plate thereof,removed.l

. pir 4being hereinafter termed a double rotary machine sustaining corner` posts 2 on` which 1s secured a top plate 2a supporting a ring 3.

ring 3 are drivers 6, each of which is ivotally connected with a type ,bar 7. Sai tvpe bar is pivoted'at 8 to one end of the'gii-ide link 9, the Vother end whereof is formed with 'crumed' at 17 on a stationary part of the machine`. The other arm o f the bell crank is connected by a draw .link 18 with an actuating 'arm-or blade 19 piv'oted at 20 to a stationary part of the machine. Integral with the arm 19 is a `curved arm 21, these arms forming an angular lever, and pivotally connected with thearm 21-is a key stem 22 provided with a key cap 23 and controlled in its up and" down movement by a guide arm 24 having a stationary pivot25.

Referring now to the tahulating mechanism, this may be of the ordinary form of con- A supporting bracket 62 is secured to the rear of the rnaehine traino by sorews 63, said brooke-t supporting a rod 64 which serves as a tule-rum for a set of verticaiiy disposed vibra-tory levers 65. The lower end of eaehlever G5 is looselyT` com nected with a horizontally disposed push rod 66, said push rod bearing in a (intachable trarne 57 secured at the front ot the base by screws 68. Each push rfid is provided with a helicalv restoring spring' 69 and carries at its forward end a key button 70. The upper end ot each lever 65 is connected by a pin and slot connection with a blade-like Stop 7l. mounted to slide fore and :ift of the machine on roller Vhearings 72, said bearings be ing supported in the upper ond of the bracket 62. As is well understood tho bladedile stops 7l are arranged sido by side a letter space distance apart and are adapted. whenv actuated, to coierato with one or more stops 73 adjustablly mounted upon a stop har 74, said stop bar being disposed longitudinally ot' the platen (il and secured to upwardly and rearwardly extending arms 'fixed to, the carriage truck .53. Soniewhat below the stop blade 7l the sides of tho i bracket G2 are provided with inwardly projecting and oppositely disposed bosses 7G which are perforated to provide bearings tor a horizontally disptrsed rook shaft 77. As indicated in Figs. l, 5 and o', the righthand end of the rock shaft projoets to a vonsiderzihle extent hoyond its bearings 76. The puriose of this extension of the rook shaft Wi presently appear. Arms 78 depend from the rook shaft 77, said arms boing provided with perforated collar portions 79 through which the rock shaft 77 passes, the relation between said arms and said rock shaft being fixed by set screws .80. 'lho arms abut against .the inner faces of the bearing bosses 7G and connected at their lower ends by a cross rod 81. lisposed between the arms 78 on the rock shaft 77 is a horizontally arranged arm Si), said arln boing provided with a collar portion 83 through which the rook shaft 77 passes, a set screwy securing said arm 1n fixed relation wlth estacas of the bifurcation partially embracing the hollow shaft 47 and being adapted to' co' operate with a collar 86 fixed to said shaft .a ove said arms by a set screw 87. When any one of the push rods 66 is operated, its associate 'lever 65 lis rocked on its pivot 64,

Asi soon as the clutc the u periarm of said leverbeing swung forwardlp moving the vstop, blade Y71 into the pathof the stops 73 onjthe carriage. lAs the upper arm of thevleier swings forwardly itgcoperates with the cross rod 81 rocking the shaft`77 and moving the bifur- `cated arm 82 upwardly, the latter acting gitudinal upward movement is thereby com municated to the shaft 47 and thel members of the, clutch-connection between the pinion 51 and the `escapement wheel 35 are disen. gaged from each other, the. teeth 44 o'f the mutilated ratchet wheel 45 separating from the crown ratchet 43. The teeth of the pinion 51 will remain inmesh with the teeth of the carriage rack 52, but will slide upwardly on said rack teeth, the pinion being elongated to permit of this u ward movemechanism is disconnected the carria e is released and is free to be drawn rapidy leftward across the top late by the usual carriage spring or propeiing means (not shown herein), the free movement continuing until one of 'the carriage stops 73 co-acts with the proje'cted 4stop blade 71.

' In order tol prevent undue shock or jar from the impactof the carriage stops 7 3 with the Aprojected stop blades 71, I provide an irnlproved carriage retarding means which wi l now be described.` An arm or support 88 projects rearwardly fromthe left-hand side of the 4top plate, being secured'thereto by headed screws 89. At its rear thearm 88 is provided with a threaded opening' which receives a shouldered pivot screw 90, the body ortion 91 of vsaid screw servin as a bearing or a swinging plate or arm 92, t e right-hand end ofsaid plate being formed with a boss or hub93 which isperforated to cooperate with ivot screw (Fig. 7) To the left of its pivot tiie swinging plate 92 is broadened to provide abottorn oribase for an annular member or ring 94 having threaded openings 95 for the reception of' heat'ledscrews 96'whicl1pass u ward through the plate92 and secure the atter-and the ring 94 in -fixed relation. The ring 94 is provided-witha circular roof orgcover 97 secured in :place by headed screws 98 which pass thrcigh it and are received in threaded o enings. in theA upper face of the ring 94. lhe cover. 9711's formedfwith a central extension or boss 99 whichifis perforated toprovide a bearing fora shnrtvertcal shaft '100. lower end of said ."sh'aft -is 'formed-mth a cylin- The drical enlargement 101 (Fig. 9) which is slotted or kerfed to receive a bar-like part 102secured in place by a pin 103,l driven throughtheenlargement 101, said bar-like part serving asA a double blade in a manner ereinafter to be explained. The upper end of the shaft. receives a pinion 104 which is secured to' the shaft by a cross pin 105. The top 97, ring 94 and base 92 constitute a casing or covered box Awithin which the doub e blade 102 is adapted to be rotated.

'It Wili, of course, be understood that said efore screwing the bottom plate 92 in placev a quantity of small, substantially spherical bodies are introduced into the casing.v I

prefer to use smallsteel balls for this purpose and such balls are shownjn the drawings and "indicated by the reference numeral 106.

Mixed with the balls' I prefer to eln loy a lubricating material, preferably fria le in character. I have in practice found powdered graphite to be most satisfactory. In the drawings the lubricating material is indicatedby the referencecharacter 107.- rlhe most satisfactory results I have found to be obtained' when the casing is about half full of ballsand lubricating material. If it is desired to retard 'the carriage to a greater or less extent however, the quantity of balls may readily be increased or lessened. Theli'alls and lubricating material having been .introduced into the casing, the plate 92 may then be secured thereto by means of the screws 96. The left or inrier end of the base limiting pin 113 is fixed inthe end of the arm 88 and projects upwardlyftherefrom. The rear edge ofthe swmging plate 92 is normally maintained against said limitin r p in by a wire restoring .spring 114 whic is coiled around the hub 93 and has one end hooked over the swinging plate 9 2 .and the other end .hooked o'ver the station-ary supporting arm A88. 'With the swin ing', late 92 in normal position against its imiting stop 113 it will be noted from an inspection of Fig. 6 that the pinion 104 is disconnected from the rack 52.

'Referring now to the operation of my improved retarding de vice, it will be understood that when the 7rock shaft 77- is rocked by one of the levers 65, the pin 112 on the end'ol' said rock shaftpwill coperate with the slotted lip 109 to swing the plate 92 forwardly vabout its pivot 90, bringing' 'the pinion104 into mesh with the carriage rack. The parts are proportioned so that the pinion 104 and rack 52 will be far enough in mesh rial, the balls tending to crowd together and; pile up on one another, forming-with the.

ibricating material, at each side of the axis of rotation a compact mass filling the space next to and in. front of the adjacent arm of the blade 'and pressing against the ringfQli. These masses become' more compact as the extent of movement of the arms of thebiade 102 increases, and the result is that the free' movement of the carriage is retarded so that the sto the projected stop-blade '71 Without excess ive violence; and the carriage is arrested with but little shock or noise, while the speed of theparriage is not-so decreased as to render the operationof the machine too slow.` lt will be understood, of course, that,

the barpr blade 102 may be replaced by any other rotary vpart of suitable construction.

V When the eo-action between 'the carriage stop and the sto on the franie occurs the actuated taloulatmgl key is released and the push rod and its associate vibrator-y lever 65 are restored to their normal positions by the restoringV spring; 60, while at the same time the clutch devices are reconnected tl'nough gravity and thc restoring spring 48, the teeth oi' the pinion 51 sliding' down over the teeth ol the carriage rack 52. The retardinpr device is restored to normal position .through the action of its spring 114 which operates to restore the swinging plate 92 to the osition shown in Fig. 6. 'l`hespring 48 a so assists in thus restoring, the rctarding device to normal position, through the collar 86,l arm 82, rock shaft 77 and pin 112, said pin acting on the lip 109 and tending to swing the late 92 rearwardly.

As has een stated, the quantity of the balls 106 may be so governed that they will oppose the rotation ot' the blade 102 and retard the movement of the carriage to any desired degree. In practice l have found '73 is brought into co-action with I most satisfactory results to be obtained 'by a .mass el: particles of solid matter of the particular character described g that is, a mixture of balls and a powdered orv pulverized lubricant. The lubricant causes smooth and easy co-action of the balls with one :un other, but of course, il' preferred, the balls may be employed alone. A v)owdcred or pulverized material which, as has been described, is preferably a lubricant vmay also be employed separately and alone in the casing with goed results, hut by .rnixinpr metal balls with said material to give weight andbod r, the size of; the casing and 'associato parts may be made smaller and thesame res ults obtained as with a large casing and a large hulk or quantity of powdered selflu bricating material alone. Any self-lubricat` ing solid other than graphite may, of course, be employed.

Variouschang'ee may be effected without. departing from the spirit of my invention.
