Specification of Letters Patent.

Application filed May 12, 1910. Serial No. 560,840.

To all whom it may concern:

Be it known that I, JoHN VVALDHEIM, citizen of the United States, and resident of Newark, in the county of Essex and State and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to means for preventing a rebound of the carriage when ltis arrested at the end of its travel, in a tabul'ating operation for example.

' The invention also relates to means for retarding the movement of the carriage during such a travel'thereof and when it is released from letter space control of the escapement mechanism.

To the above .and other.ends m invention consists in the features of construction, arrangements of partsand combinations of device to be hereinafter described and more particularly pointed out in the appended claims. y

arts shown in; an'view of'the form of anti-rebound construction e'mbodying my invention. Fig. 11 is a side elevation of the same with parts in section.

I have only shown in the so much of a complete ty writing machine as is necessary to an un erstanding of my invention.

In Figs. 1 to 5 and 7 and 8 I have shown my invention embodied ina machine similar to the No. 11 Reminlg ton machine, whereas in Figs. 10 and 11 have shown in invention embodied in a machine resembling the No. 6 Remington machine. .It will be seen from the followin description that the invention may be embo ied in either of these machines without modifying,

modifying, saidmachines as they now exist.

It should be understood, however, thatthe be embodied in various styles invention may of typewriting machines. v

Referring more particularly to Figs. 1 to 5 of the drawings, the frame of the machine will be seen to comprise a base 1, corner The escapement mechanism which control'sthe carriage in its letter space movements, as shown in Figs. 1 to 5, comprises a feed rack 10 secured to the rear ends of arms 11 pivoted at their forward ends, as at '12, to brackets 13 lixed on the rear cross bar or guide rail 7 of the carriage. A leaf spring 14.. secured at one end by a screw 15 to the rail 7 of the carriage and bears 'or materially I downwardly at its free end on one of the arms 11 to press the'rack 1O downwardly.

A feed pinion 16 is fixedly mounted on the forward end of a shaft 17 which turns in a bearing 18 fixed to the topplate of the machine. The rear end of the rock shaft 17 has.

two relatively adjustable eseapeinent wheels 19 secured thereto so that. the escapement that for the purpose of the present invenwheels are fixed relatively to each other and 5 tion any tabulating mechanism may. be cmare fixed to turn with the feed pinion and its shaft 17 in both directions. The escapement wheels 19 are preferablyadjusted so i as to bring their teeth out of register, as shown in Fig. 3, and to provide a drop from one wheel to another. A feed dog 20 is pivoted at 21. to a dog rocker and is adapted to cooperate first with one escapement wheel and then the other in the vibratory movement of the dog rocker back and forth and thus afford a letter feed movement of the carriage. The dog 20 is extended beyond its pivot as at 23 where it cooperates with the dog rocker to limit the upward movement of the (loginto engagement with the escapement wheels. An expansion spring 24 is received in a cut-out in the dog rocker 22 and bears at its lower end against the bottom wall of the cut-out and at its upper end against the feed dog 20 to normally maintain itin the elevated position shown in Fig. 3. The dog rocker'is cut away at 25 to afford a downward movement of the-fced dog 20 around its pivot 21 against the spring 24; the feed dog being pressed downwardly by the engagement of one of the escapement wheels therewith during the reverse rotation of the escapement wheels. The escapementmechanism .thus far described is practically the same as that. embodied in the No. 11 Remington machine and is substantially the same as that shown in the patent to Yaw dated Dec. 28, 1909. No. 944,303. The dog roeker 22 is pivoted at 26 and is provided with a forwardly extending arm 27 connected to a downwardly extending link 28 which is actuated at each printing operation as in the No. 11 Remington machine. The dog rocker and the parts associated therewith are restored to normal position by a spring 2-9 connected at one end to a pin 3Q which projects from the dog rocker and at'its opposite end to a pin 31 which extends from .a bracket plate 32 to whichthe dog rocker is pivoted. be understood that a step-bystep letter feed movement of the carriage in the direction of its feed is effected by the usual s ring drum a at each forward and backwar movement of the dog rocker in the usual manner, the

feed dog 20 moving from. one escapementwheel 19 to thenext and back again.- A disengagement 'of the carriage from step-by -step control of the escapement mechanism may be effected by lifting the feed rack 10 in theusual manner andmay also be-etfect- J ed by means which will be hereinafter described.

5-1 have shown embodied in thc.present "construction tabulatmg mechanism similar to thatemployed in the No. 11 Remington machine. Tt should be understood, however,

It should ployed.

: arms 33 are secured to the carriage and support a toothed column stop bar along which bifurcated column stops 35 may be adjusted. A series of denominational stops 36, each formed asa partof a downwardly extending stop-carrying lever 37, is provided. The levers 37 are vpivoted at. 38 on a pivot rod fixed at its ends in a tabulator frame 39 secured to the frame of the-machine in the usual manner. The denomina-- tional stops 36 extend through openings in a guide plate 40 fixed to the tabulatorframe 39. The lower ends of the denominational stop-carrying levers are connected to links 41 which in turn are connected at their forwardends to angle levers 42 pivoted at 43 I tile spring 46, the opposite end of said spring being connected to a plate 47jfixcd on the frame. The key stems 44 are guided in guide openings in theplate 47 and in a plate 18. I

The carriage releasing means controlled by an actuation of the tabulator mechanism comprises a lever-like carriage release frame 49 49 pivoted by. a rock shaft 50 to a depending bracket 51 secured by a screw 52 to the top plate of the machine. The lower part of the frame comprises two depending arms 49 arranged outside of the tabulator levers 37 and fixedly connected at their upper ends to the rock shaft 50. The lower ends of the arms are united by a cross-rod 54 which extends back of the lower end portions of the levers 37 so that 'a rearward movement of the lower ends of any of the levers 37 effects a correspondin movement of the lower end of the release rame. The

upperpart of the release frame comprises a crank arm 49 fixed to and located centrally of the. rock shaft 50.

A spring 53 surrounds the rock shaft 50 and is connected at one end to the bracket 51 and at its opposite end to the crank arm 49* so as to tend to force the upper end of'the release frame towardthe rear of the machine.

The up? per end of the crank arm 49* is forked at" 55, the forked ends being receivedin a cirlcumferential grooveISG in a releasingdevice 57. The releasing device comprises a spindle 58 received in bearings 59 and G0 in the top plate of the machine so that the device 57 is sup orted for both a.- rotative movement-and or longitudinal movement in its bearings. The releasing member 57 has afrusto-conical engaging portion 61-" which is adapted to coiiperate with the lower edge of a rack'62 connected by screws 63 to depending arms 64 which are secured at their the feed pinion 16 on opposite sides thereof. The rack 62 is normally out of engagement with the feed )inion and is carried up into engagement with the feed pinion when the teed rack 10 is disengaged therefrom so as v to efiectan operative connection between the rack 62 and the escapement wheel when the feed rack 10 is disengaged from the pinion to release the carriage from a step-by-step control of the escapement mechanism.

The efiect of disengaging the rack 10 from the feed pinion and engaging the rack 62 therewith is to cause the escapement wheels to be rotated in a direction opposite that which they ordinarily receive during the step-by-step teed movement of the carriage. This operative connection between the rack 62 and the escapement mechanism at the time when the feed rack 10 is disengaged from the escapeinent mechanism is effective to prevent a rebound of the carriage when it is arrested by the tabulating mechanism after a free travel of the carriage. Thus an actuation of a tabulator key 45 is effective to move the associated denominational. stop 36 into the path of one ofthe column stops 35. This same movement is eitective to move the crossbar 54 rearwardly, thus moving the releasing device 5? forwardly to cam up the

racks

62 and 10, releasing the rack 10: from its cooperative feed pinion and throwing the rack 62 into engagement with the pinion. The full extent of forward movement of the releasing device 57 is elleotive to string the cylindrical portion or dwell'tll of the cam into contact with the lower edge of the rack 62, thus holding it in effective engagement with the feed pinion until the releasing device is again moved rearwardly when pressure. on the tabulator key is released. By releasing the feed rack 10 from the pinion in the manner described and cngaging the rack 62 with the pinion, the escapeinent wheels are caused to rotate in a direction opposite tothat in which they rotate during a step-bystcp feed movement of the carriage. During this reverse rotation of the escapement wheels the feed dog,

as hereinbeforc pointed out; is moved away from the escapement wheels by contact between the rear faces of the teeth of the engaged escapement wheel and the inclined rear side of the feed dog. W'hen the carriage is arrested by the cooperation of one of the column steps 35 with the projected denominational stop, the feed dog 20 will be in a position to engage with its working face a tooth of the normally engaged escape:

merit wheel and will prevent a rotation of the escapement wheels in the letter feed 65 direction, thus resisting and preventing a rebound ofthe carriage. In other words,;the connection of the rack 62 with the escapement wheel tends to turn it in the direction opposite that which it receives when it is engaged by the feed :rack 10 and an impact between the tabulator stops would therefore tend to cause the escapement wheel to be turned in the direction of the movement of the escapement wheels during a letter space operation. This movement, however is resisted by the feed dog 20 and the carrings is therefore prevented from rebounding.

tarding means which tend to retard the movement of the carriage when it is running free at tabulating operations. I have provided in the construction shown in Figs. 1

to 5, inclusive, retarding mechanism whichv 5 comprises a bracket 66 pivoted at 67 to rearwardly extending'bracket arms (SS-secured to the top plate of the machine by screws 69. The bracket 66-has a cross bar 70 with which the denominational stop levers 37 coiiperate.

This bracket 66 is provided with arms 71 which are pivoted to the bracketon shouldered pivot screws 72. The arms extend upwardly from their pivots on opposite sides of the escapement wheel, as shown in Fig.

and are adapted to turn on their pivots filw'tlld and away from the center of the escapement wheels. A spring 73 surrounds the hub of each pivoted arm 71 and is connected at one end to a pin H carried by the bracket, the opposite end 75 of each spring being connected to. the arm and tending to rotate itaround its pivot toward the escapement wheel. A stop or arm 76 projects from each of the pivoted arms 71 and cooperates with the pin 74. to limit the movement of thet'ree end of the arm Tl toward the escapement wheels. The free end of each arm 71 preterz-ibly carries an anti-friction roller 77 which is adapted to hear at its periphery 119 against the teeth of the rear cscapement wheel whenpa denominational stop is proiected into the path of the column stops and the carriage is relcased from. the stepby-step control of the cscapement mechanism. Thus a depression of'a tabulator key 45 is efi'ective to move theupper end of the associated denominational stop lever for wardly, projecting the. denominational stop 36 carried thereby into the pathot' a 001- 120 umn stop on the carriage. The forward movement of the stop carrying lever 37 is eliective to movethc cross bar YO-iorwardly from the position shown in l 1 to that indlcated in Fig.4. thereby moving the} spring pressed arms .7l for ardlyhto a'position WllQIQ the anti-friction rollers 77 will be broughtinto cotiperation with the teeth on It may be found desirable to provide g0 the rear escapement wheel. The same movenient of the denominational key effects a release of the carriage in the manner hereinbefore described, causing the rack 62 to be engaged with the feed pinion. The spring pressed arm 71 bearing against the periphery of the rear escapement wheel tends to retard the rotative movement transmitted to both escapement wheels by the rack 62 during the travel of the carriage when it is freed from the step-by-step letter space cons trol of the escapement mechanism. lVhen pressure on the depressed t-abulator key is released, a spring 7 (5,connected at one end to the swinging bracket 66 and at its other end to a fixed bracket arm 68, disengages the retarder and restores it to normal position. From the foregoing description it will. be understood that the esca-pcment mecha nism enters directly into and constitutes a part of a means of retarding the tree travel of the carriage and for preventing a rebound of the carriage when it is arrested by the tabulator stops.

The construction shown in Fig. 6 is some what similar to that hereinbefore described except that in the modified construction the bearing 18 instead of being fixed to the top plate of the machine is pivoted thereto at 78 at a point which is in line with the point of engagement between the feed dog and the rear eseapement wheel, so that the bearing 18 carrying the cscapement wheels and feed pinion, 1S adapted to turn on the pivot 78 to effect a relative movement between the feed pinion and the

racks

10 and 62*, which in tlns case are fixed to the carriage. The swinging movement of the bearing 18? and the parts carried thereby, may be produced by an arm 79 having a cam groove 80 therein for cooperation with a pin 81 which projects laterally from the bearing 18 A movement of the arm 7 9 isthus efi ective to bring about a disengagement of the feed pinion 16 from the feed rack l and to cause said p)inion to engage the rack 62 and vice versa.

tiring the engaging and disengaging move--. ment between the pinion and racks the feed dog 20 maintains its engagement with the rear. escapement wheel. The engagement .and disengagement between the feed rack.

and escapement pinion is effected in the genw oral manner disclosed in the Vebb Patent I In the construction shown in Figs. 7 and 8 the double escapement wheel 19 is providcd with a rearwardly extending pin 82 to which one end of a coiled spring 83 connected. The opposite end of this spring is connected to a pin 8-4 which projects from the rear 'face of a disk 85. The disk is provided with ahub 85 mounted to revolve freely on the hub 85 of one of the escape ment wheels. A. set screw 85 s received wvard each other.

in a tapped opening in the hub 85* and bears at its inner end against the shaft 17. It is by this means that the cscapement wheels are secured to the shaft. The disk 85 is held against outer displacement along the hub 85 by collar 86 fixed to the shaft by a screw 87. The periphery of the disk 85 has outwardly extending projections 88 thereon, two of such projections being shown in the present instance, though it should be understood that any suitable number of projections may be provided. Arms 71 are pivoted at 89 to a bracket 90 pivoted upon screws'9l carried by a fixed bracket 92 secured to the top plate of the machine. The arms 71 are connected by a contractile spring 93 which tends to draw the arms to- Pins 94: are carried the bracket 90 to limit the inward movement of the arms 71*. Each arm 71 carries an anti-friction roller 77 which, as shown in Fig. 9, is preferably beveled on one edge thereof, as indicated at 95, so that a forward movement of the bracket 90 will force the arms slightly apart against the pressure of the spring 93 as to cause the anti-friction rollers to engage the periphery of the disk 85 and as the disk rotates, to cooperate with the projections 88. A rearwardly projecting arm 96 extends tromthe bracket 90 and is provided with an arm or cross bar 70 with which the denominational stop levers 37. are adapted to cooperate. A forward movement of any of the denominational stop levers is effective to move the bracket .90 forwardly around its pivots 91 and to force the anti-friction roller 77 into cooperation with the disk 85 at the periphery thereof.

The spring which connects the disk 85 with the escapement wheels constitutes a cushion spring which is rendered effective by the lost motion connection between the disk and escapenient wheel. This cushion spring and lost motion connection absorbs the shock when the retarding mechanism, is thrown into operation and prevents undue shock. The carriage may therefore be gradually re tarded without givingan undue jerkingmotion to the carriage by the operation of the retarder. The elasticity of the connection between the retarding disk 85 and the carriagc, eil'ected tl-irough the spring 83; p'revents an undue jar of the carriage when the springpressed arms 71 are brought into cooperation with the projections 88 on the disk. A spring 97 is connected at oiieentl to the bracket 90 and atv its opposite end to the bracket 92 so as to restore the bracket 90 to its normal position when the actuated denominational stop lever is In the construction shown in Figsflll and 11 the escapement wheel shaft 17 has posi} Jtively connectedthereto a drum or housing 98 which is fixed to the drum by a set screw 99, threaded into a tapped opening in the hub 100 of the drum and bearing at its inner end against the escapement wheel shaft.

The drum carries a pivot 101 for a pawl --with a ratchet w eel 104"fixed to a single escapement wheel 19 which affords a free rotation of the escapement wheel shaft 17 in one-direction. pressed toward the escapement wheel and is adapted to engage therear faces of the teeth 102 pressed by a spring 103 into engagement thereof to prevent a backward rotation of the escapement wheel. In this constructiona step-by-step feed movement of the. carriage is effected durin the engagement of the rack 10 with a fee pinion, corresponding .to the feed pinion 16, which is .connected to theescapement wheel-through the pawl 102 and ratchet 104 so that when the feed dogs 20 are actuated the pressure of the carriage spring a' is effective to move the movement of the drum. At this time the,

eseapement wheel is held against backward I rotation by the awl105. When the column' stop is arrest by a projected denominational stop there will. be a tendency of the carriage to rebound, which will tend to move the rack 62 to the right. This backward or rebounding movement of the rack 62 will be resisted and revented in the following manner-c lt ten ency of the rack 62 to .re-

bound; while it is in engagementvwith the feed inion will tend to turn the drum 98, and t e pawl 102 carried thereby, in the direction of the arrow in, Fig. 10 and'the ratchet wheel 104 being connected to the escapement wheel will be resisted in its movement in this direction by ,the engage- .ment of a tooth of the eseapement wheel with the normally engaged feed dog 20*. It will therefore be understood that any tendency of the carriage to rebound, when it is arrested b its tabulator-sto s, will be resisted an prevented by t'e' escapement 55 mechanism controlled at' this time through the rack 62"..
