To all whom it may concern.'

zen 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 Machines, of which the following isa specification.

This invention relates to carriage retarding devices for Atypewriting machines and consists in theu features of construction and combinations and arrangements of parts which are hereinafter described and'specii'ied in the claims.

ln the accompanying drawings in which like reference numerals designate like parts in the different views, Figure 1 is a rear and sectional elevation of the frame and parts of the'inechanism of a Monarch typewriting machine, to which carriage-retarding mechanisin embodying the invention -is shown applied; Fig. 1a, a fragmentary side view of parts shown in Fig. 1; Fig. 2, a vertical section, at right angles to the plane of Fig. 1, of said Iframe and parts of the mechanism of the machine; Fig. 3, an enlarged vertical section of the upper rear part of the machine, the section being at right angles to the axis of the platen; Fig. 4, a front elevation of the carriage-retarding mechanism and of a lever operative to engage one of the parts thereof with the carriage, and a vertical section of a fragment of the top-plate; Fig. 5, a front elevation of the mechanism shown above the top-plate in Fig. 4,' the positions of the parts being different from those shown in Fig. 4; Fig. 6, a side and sectional elevation of parts shown in Figs. 3 and 4, the section being on the planes x-Q/J, Fig. 4, and the positions of the parts being different from those shown in any other iigiire; and Fig. 7, a section of parts shown in Figs. 1 and 3, c25 seg. to 6 inclusive. n

Although the drawings illustrate this invention applied to a Monarch machine it is to be understood that it is also applicable to numerous others, including such as aie ycalled under stroke machines, 'as well as t visible-writing machines.

The carriage-rctarding mechanism iii which the invention is embodied is attached `to the top-plateA of the machine near its rear 4edge and 0n the right, preferably, of a vertical plane containing the axis of the escapement pinion. The frame of the machine is composed of the base 1 and four posts 2, onlyth'ree of which are shown, and the top plate 3. On the back partof the top-plate 3 are two standards 4, which are fastened to the top-plate and to which upper and lower guide rails 5 and 6 are attached by screws 7, these guide rails having in them grooves 8 and 9 extending throughout the length of the rails. Thel carriage 10, in which is mounted the platen 11, has formed enit grooved guides 12 and 13, which Aextend from eni to end of the carriage, the grooves 14 and 15 of these guides forgning with the grooves 8 and 9, of the rails 5 and 6, ball 0r roller channels in which are shown anti-friction balls 16 and 17. The carriage is thus supported by the rails 5 and 6 and is movable on the balls in opposite directions over the top plate 3. The guides 12 and 13 are connected together by a web 18, and through holes in this web extend arms 19 which are pirotedto the ends of the carriage, and tol whose rear iends is affixed the carriage-rack 2O behind the web 18, the rack being movable up and down on the pivots 21 of the arms 19. Springs 22, acting on the arms of the rack, tend to keep the rack in the position in which it is shown in Fig. 3, that being its normal position.

The rack 20 normally engages a pinion 23 which is fast on a shaft having a bearing in a bracket 24 affixed to the top plate 3, and on the rear end of this shaft is an escapementwheel 25, arranged to co-act with feed dogs 26 and 27, mounted on a dog rocker 28, whose rock shaftl 29 is pivoted at its ends between lugs on a bracket 30 affixed to and extending downward from the top plate 3. On the rock shaft 2Q is a spring 31 which tends to keep the steppingdog 2,7 in engagement with a tooth of the escapeinent wheel 25. An arm 32, fast 0n the dog-rocker, extends in front of the rock shaft 29, and to the front end of this arm is secured a link 33 which extends downward therefrom to the universal bar of the machine. Whenever the universal bar is actuated by depressing a character key orspace key, the front end of the arm 32v is drawn downward by the link 33, the stepping dog 27 is swung forward free from the escapenient-wheel, and the holding dog 26 is moved into engagement with the escapenient wheel, and when the universal bar rises after the key has been released, the stepping dog27 ren- 1 depressed, and the link 37 rocks the bar 44, gages with the escapement-wheel and the car- .1 bringing the lugs 46 into the path of the ria e advances aletter-space distance.

A pin 59 fixed on the key lever 53 of the block 7 2 and the shaft. extending extends through the slot 52 in the ear 51, of through the block and having on it a collarS() the lever 48. The construction is such that which fits close to the rear face of the block when the key 54 is depressed, the lever 48 is and which is secured to the shaft by a screw 13o to be actuated by the carriage 81.- A roller 82 is mounted on the arm 77 by means of a shouldered screw 83 extending into the arm. Under the block 72 is an angular lever, having arms 84 and 85, this lever being pivoted by a pin 86 between lugs'87 on the base 68 of the posts 69. The arm 85 of the pinion 76 engaging the rack 20 and raising 1t out of engagement With the feed pinion 23, thusreleasing the carriage from the escapeme'nt mechanism. When the block isin that position the arm 84 of the angularlever is upright, the axis of the roller 90.being directly over that of the pin 86.

On the front-face of the standard 66 are a pivoted arm 91 and a spring 92, the arm be- 'ing pivoted to the standard by a screw 93, and the spring being secured in a slot inA a screw 94 which passes through the standard and on which is a lock-nut 95 bearing against the back of the standard. The spring 92 bears on the top of the pivoted arm 91 and tends to keep this arm in contact with a sto -pin 96 fixed in the standard, as appears by ig. 4 in which the arm 91 is shownmty its normal position. The lpressure of the s ing 92 on the arm 91 may e regulated by t rning the screw 94 and locking it by means of the lock-nut 95. The arms 77 and 91 are Aso arranged that when the block 72 is in the position shown in Fig. v6 and the shaft 75 is rotated, the roller 82 of the arm 77 will be moved into contact with thelower face of the arm 91, and that the arm 77 must force the' arm 91 upward out of the `path of the roller 82, against the pressure of the spring 92 to enable the shaft 75 to make a com lete rotation, the roller being moved into t e space normally occupied by the arm 91. The action of the arm 77 in forcing the arm 91 upward, as just described, is illustrated in Fig.

5 of the drawings, the dotted circle indicating the orbit in whichthe end of the arm 77 travels. Whenever the block 72 is restored to its normal position, the action of gravity on the arm 77 causes this arm to assume the position in which it appears in Fig. 3, so that the arm 77 normally extends from the shaft 75 on the opposite side thereof from the arm 91.

AT he teeth of the pinion 76, which preferably has ten teeth or about that number, are properly formed to engage with the Iteeth of the carriage-rack 20, and'when this pinion is in' its normal position, or that shown in Fig.

rack. sc thatthe rack'may move in either dif motion.

rection with the carriage without' touching the pinion 76. When the pinion 76 is raised from its normal position to that in which it is shown in Fig. 6, it engages withv the carriagerac'k 20 and raises the rack out of engagement with the escapement-pinion 23, so that motion may4 then be communicated by the carriage to the shaft 75 through the rack 20 and pinion 76.

The machine contains a spring-drum 97 which is connected by a strap 98 with the carriage so that when the escapement is actuated, or the carriage-rack is raised out-of en- `gagement with the pinion 23, the carriage will be moved toward the left by the action on it'of the spring-drum and strap.

When the tabulator key 54 is depressed the stop bar 35 is turned on its axis by the action of the lever 53 on the lever 48 and of the latterlever and the rod 37 on the crank arm 36,

the lugs 46 on the tabulator-stops45 being moved downward into alinement with the stop 47 on the carriage. At the same time the projection 39 on the collar 38 fixed to the rod 37 forces downward the arm 6() of the lever 60-61, and the' angular lever 84-85 is actuated, the block 72 being moved on its pivotal axis to the position in which it is shown in lFig. 6. The carriage is then drawn rapidly towardthe left by the action on it of the spring-drum`97, and as the pinion 76- is turned by the carriage-rack the arm 77 is rotated and acts once during each rotation on the arm 91' as above-described. v

The upright arm 84 of the angular lever so supports the block 72 that little or no shock is transmitted to the iinger of the operator on the de 'ressed' tabulator-key 'when the arms 77 an 91 coact with each other. Since the arm 77 extends from the shaft 75 on the opposite side thereof from the eo-acting arm 91, when the pinion 76 is raised into engagement with the carriage-rack, the carriage then moves for several letter-space distances before the retarding devices co-act to check its The carriage therefore starts uickly, and while the arm 77 travels towards t e arm 91, the motion of the carriage increases. When the arm 77 acts on the arm 91, the carriage is momentarily retarded by the resistance of the spring 92, a movement of the carriage for about three letter-space distances being required while the arm 77, or the roller 82 thereon, is in contact with the other arm. The carriage will be so retarded whenever the arm 91'is raised by the arm 77, until the stop 47 meets the lug 46 of one of the tabulator stops. When the carriage is arrested, it being thenless than ten .letter spaces distant from where it was last subjected to the retarding action of the devices 77 and 9] --92, its momentum is not great enough, if the pressure of the snring 92 is properly regulated, to render the noise excessive or to expose the machine to injury.

. claimed. herein may The osition of the 'escapement pinion 23 with relation to the carriage-rack 20, when the rack isoperatively engaged with the pinion 76, is indicated by dotted lines in Fig. 6.' The tabulator-key and stop-bar are restored to their normal ositions by the springs 57 and .42, andas t e collar 38 on the rod 37 rises, the spring 6 4 restores the lever 60--61 and the an ular lever 84--85 to their normal positions, t e carriage-rack descends on the escapement-pinion, forcing the pinion 76 downward, and the block 72 gravitates to the position shown inFig. 3, carrying the pinion 76 entirely below the carriage-rack.

It is to be understood that the invention be embodied in mechanism differing in details of construction or arrangement of parts from that which has been specifically described above, and that it may be ap lied to machines containing denominationa or decimal tabulating mechaniism, instead of the particular tabulating mechanism shown herein, or other forms of columnspacing mechanism.

I do not intend to restrict the invention to mechanism composed of a rotary device; like the arm 77 vand a single coperative device including a spring, it being evident that a pluralityi of spring-pressed arms 91, or simiar devices, may be arranged to'coperate successively with the arm 77, and it being my purbse to also utilize the in vention, if desire 'It will be seen from the Jforegoing that .I have provided means for interrupting the motion of the carriage a plurality of times during a sin le run,` orduring the travel of the carriage rom right to left when released from the control ofthe escapement mechanism. `These successive interruptions operate to break u or diminish the speed and striking force o the carriage. and to such an extent that even when the carriage is released -to run for its maximum-travel, it will finally be arrested by the tabulator stops or margin sto s Without undue noise or shock, and with no iability of breaking or Ainjuring any of the parts of the machine. It will be understood, of course, that the said interruptions of the motion of the carriage do not eiect a coin-y plete stoppage .of the carraige at any one of the plurality of interrupting points, but on' the other hand, that these interruptions are caused intermittently by the interposition of obstructing devices relatively weaker than the momentumof the carria e, and which operate momentarily or perio ically to slacken lthe pace of the carriage and absorb some of the striking force which the carriage would otherwise have if left to continue uninterruptedyntlo the end of its travel.'
