Application filed October 25,1902. Serial No. 128,756.

To all whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at llhrltord, in the county. of Hartford and State ol Connecticut, have invented certain new a nd usei'ul Improvements in Mechanical Movements, of which the following is a specilication. 4

This invention relates to an organization of mechanism designed for bringing to a workl l l talities which may thereupon be utilized for performing a particular species of operation.

This invention is designed more particu larly for employment in an apparatus or mechanism wherein a series of members is caused to move past a station continuously, but which series ofmembers is capable of be ing halted with one of the members opposite the station, and subsequently to such arrest permitted to proceed and caused to halt with a di'lierent member opposite the station when desired. The members if desired may be instrumentalities for performing operations of various natures, which may be similar in kind but may vary in detail.

The new mechanical movement herein set forth mayadvantageously be'employed in organizations embodying a number, of movble ol' cooperating-with another device at the the desired member shall be mechanically selected and that the cooperative device be mechanically actuated.

()neof the objects'of the invention is to provide a new mechanical movement where by the desired member may be readily and precisely selected and positioned and the co-' tion of a part of the selecting mechanism and whereby after the cooperation of the member and device the selecting mechanism will release the member and by the movement caused by such release will actuate a detent to maintain the member theretofore selected at position, and if it is desired that the memi her-last employed shall again cooperate with the cooperative device .the detent will hold the member at position until the selecting l sumed a position to hold the member at the working point without appreciable movc- 1 ment of the member, and as often as it is desired to'repeat the cooperation of the device i mechanism will relieve the detent and cow ate the cooperative device and permit the detent to again detain the member at position.

In the drawings attached to the present with the member at position the selecting specification, there is illustrated a practical application of this new mechanical movement; the instrumentalities or members are shown type-dies mounted upon a carrier, which is shown as friction ally connected with ower-driving means for continuous rotation, liut held against rotation with one of the dies in the printing position and in which position it remains'as long as that particular die is desired for use. U )011 the operation of a selector to di'lierent y position the carrier (one selector being provided, in the organization shown, for each type-die) the carrier will shift until the die corresponding with that selector is brought into the printing position.

In the form of my invention here illustrated the carrier is normally held stationary by means of a detent, and upon the operation of a selector the detent withdraws its hold and the carrier is permitted to mo e forward until arrested by the selector, unlessthe. selector for the die which is in the printing position is actuated, when the detent will be moved from its engagement with the carrier and the selector moved into engagement therewith without an appreciable movement or clumge of position of the carrier.

In the drawings accompanying and forming part of-this specification a form of my'invention is shown as applied to a typewritingmachine, wherein Figure 1 is a plan view Figs. 2 and 3 are side views in section showing the device in different positions. Fig. 4 is a plan in section on line -.r;21 of Fig. 3 and Figs. 5 and 6 are detail views of a form ofesoapement.

' The various parts of the devicemay be mounted upon some suitable framework, designated in a general way by A, and in the present instance comprising a base or floor portion 7 provided with u)wardly-project: ing side walls 8. The wor king instrumentalities ormembers, in the present instance impression devices or type-dies 9, are shown mounted upon a carrier or Wheel 10 having projecting upon each side thereof an elongated hub 11. The carrier may be mounted upon a shaft 12 journaled in hearings in the for regulating the friction.

The form of typewriter illustrated herein is thatwherein amovable hammer andpl'aten are employed to drive the surface of paper and an ink ribbon against the type-dies. The types are moved into the printing position opposite the platen each time a different character is desired to be employed. The platen indicating the working or printing point in the presthe ot ier of the hubs of the carrier.

ent instance is designated in a general-way by b. The hammer, designated in a general vway by c, is shown as comprising' a head 16 located at the end of a curved operating rod 16 pivoted at 17 to a bracket 18 rising from the fioorof the framework. g I In the present organization each impression device is shown as having its own positionin stop-finger 19 projecting from one or The stop fingers are shown asradially projecting. There ma be provided for each stop-finger a selector, desi nated in a general way by cl. The series of se ectors in the present instance embody upright members 20 provided at their lower ends with hubs 21 which are shown as mounted upon a shaft 22 journaled in the frame of the machine in bosses 23. The hubs serve to s 'ace the selectors. Suitable springs, here s iown as leaf springs 24, may be employed for normally holding the selectors out of the paths of the fingers. The forward or initial engaging edge of the selector and the edge or initial engaging end of the arresting fingers may be chamfered or beveled oil, as at 1'9, 20, respectively, for the purpose of permitting the selector to be pushed under the finger when it is desired to repeat the character which has just been printed and thereby compensate for any tendency of the carrier to move forward during the change of detaining devices, whereby the carrier will be repositioned in case any slight movement occurs.

Each selector is shown as operated by a finger-key bearing a character or exponent corresponding with an impression device or die upon the carrier. In the present instance letters of the alphabet are shown as the devices upon the working members or instrumentalities, in, the present instance dies;

There are, however, for the purpose of illustration herein but sixteen characters employed. It is understood, however, that the drawings herein merely illustrate a tangible form of employing the invention. The varic5 ous parts of the machine will, of course, be

made in such form as the exigencies of the case may demand. Suitable material and structure of the parts will be determined by the builder.

The key-levers, designated in a general Way by 25, are each shown as comprising a finger-key 26 connected with the longerend 27 of a lever loosely mounted by means of spacing hubs 27 upon a shaft 28 journaled in the frame, in the present instance in bosses 29. The shorter arm 30 of each lever is shown as bending downwardly and sidewardly and ending in a cam face 31 for engaging the selector and forcing it; into the path of the finger of the hub of the carrier.

Forthe purpose of normally holdingthe carrier in a stationary, position against the impulse of the friction driving-wheel a ratchetwheel 32 is shown as mounted fast u the driving-shaft, with. which ratchet-w eel engages a pawl, in the present instance shown as comprising one end 33 of a bell-crank lever other arm of the bell-crank lever comprises a pair of arms 36 mounted upon the rock-shaft and projecting forwardly of the machine and connected by a bar 37 projecting under all the key-levers. A suitable leaf spring '38 may be provided for returning the pawl'to its normal or engaging position.

For the purpose of aotuatin the hammer transverse bar 40 connecting a air of arms 41 secured to a rock-shaft 42 ournaled in bosses 43 in the side frames, which arms may be provided with suitable leaf springs 44 for returning them to their normal positions. Shown as projecting rearwardly of the rockshaft 42 is an arm- 45 occupying .a position beneath an arm 46 projecting-from the lower portion of the haft to the hammer Projecting upwardly from the arm 45 'i's a. pin 47 traversing. an opening in the arm 46 from arms 45 and 46 may be a coil spring 48. A set-nut 49 may be provided upon the upper A suitable catch may be employed for holdat each depression of a keyever there is, shown as located beneath the key-levers a mounted upon a rock-shaft 34' having bearings in bosses 35 in the side frames.

The paper 56 in the present instance is' shown as rolled up inside of an open-sid-ul tubeor pocket 57 secured to a carriagewhich is shown as mounted in ways us; socured to the sides of the frame. The paper is shown as passing between a pair of rollers 59, 60, one of which rollers i'nay be provided with a hand-wheel 61 for moving the paper.. "lhe paper is shown as guided out of the machine by a plate bland as p ssing between the type-carrier and the platen.

For the pur )ose of forming impressions a suitable inking ribbon as may be employed, which is shown as wound upon spools 64 mounted at suitable places on the ends of the carriage, the ribbon in the present instance being interposed between the paper and the impression dies.

lior the purpose of advancing the carriage in the line of its u ork a suitable spring 65 is showii secured to some convenient portion of the carriage, in the present instance a pin to projecting through a slot 37 in the Ways, and as secured to some lixed portion of the frame, in the present instance a lug 68 mounted at the end of a sleeve 6/.) for accommodating the spring when the carriage is toward A suitable escapement may be employed for permitting the carriage to ad' Vance step by step to accommodate the printing, and in thepresent ii-istance a rack 70 is shown as provided upon the lower-portimi ol' ihccarriage, The portion of the escapement for cooperation with the rack is shown mounted upon a rock-shaft 71, mounted in the present instance in, bosses in the frame ol' themachine, and as comprising a block 72 secured to the rock-shalt, to which block is pivoted at 73 a bifurcated head 74 having rigid therewith an arm 7 5 adapted to engage the teeth of the rack. Pivoi'ed to the arm 75 is shown an arm 76, the pivot passing through a h1gor boss 77'on the side of the arm 75. There are shown a pair of pins 7.-'), 80 secured to the movable arm for limiting its movement relatively to the other arm. A suitable spring may be employed, as shown at 1; for returning the movable arm against the lixed arm. For rocking'the shaft and oscillating the eziscapcment 2. depending arm #43 may be secured to the rock-shalt 71 and an arm 83 secured to the rock-shaft'34 of the carrier pawl. The ends of the arms may be i connected by a link 84, whereby upon each rise of the key-lever the arms of the escapeof the impetus of the spring of the carriage the fixed arminto the tooth of the rack next to that occupied by the loose dog. The loose dog will then he returned by the spring into a position to pass into "the. tooth occupied by the -fixed arm, so thatthe carriage will he movedforwardthe space of one tooth upon each release or rise of aliey-levcr. The

; fore described is as follows:--Upon the depression of a key-lever the pawl Withdrawnfrom the rack holding the carriage in a stationary position and the cam face of the key-lever will force the selector into the path of the arrestin finger upon the hub corresponding to the selected device upon the carrier. 7 Upon the engagement of the linger with the selector the'c'arrier Will be stopped with the selected device opposite the platen. Upon further depression of the hey the spring interposed between the arms oi" the hammer and the actuating arm will be compressed until the catch is tripped by the engagement of the bell-crank lever by the set screw, when the hammer will fly forward responsive to the spring and carry the platen, the paper and inking ribbon against the type. Upon the release of the key-l ever the escapement is oscillated andthe carrier moved forward one step or a predetermined distance between the centers of the printed characters. Upon releasing the key the hammer will assume its normal position, the plunger ridingpast the catch and holding it in position for the next action, and the spring'will push-the selector from engagen'ient with the finger, but before it has entirely lost engagement therewith the pawl 'will engage the ratchet wheel upon the driving-slraftv and hold the carrier in a stationary position. If the character is to be repeated the carrier will not be )ermitted to advance but the selectorwill be pushed under the finger before the pawl has released the carrier, so that as often as 1t-1s desired to repeat the character tE=e only inovem'ents will be the hey-lever, cnanging of detents for holding the type-terrier, the advance of the paper mrrriagee-nd the action. of the hammer.
