To all whom it may concern:

Be it known that 1, Rumors H. RICHARDS, a citizen of the United States, residing at 5 Ha'l'tford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mechanism for Operating Adjustable Work-Performing Members, of which the following is a specification.

This invention relates to an organization pf devices adapted for cooperative association with one or more members each of which may be capable of and upon adjustmentis designed for performing work of some description.

' In many classes of mechanisms and machines embodying members such as ha. e just been referred to, it is material to the performance of the functions for which such mechanisms or machines are designed that each of the adjustable members (provided there are a plurality thereof) should be capable of being freely shifted and'brought into' a p redetermined osition in order that the member may properly coo crate with the object or; surface upon whic it is to act. It is moreover highly important, in a ,practical working machine, that such member when it shall have been adjusted and is in the act of-performing its intended function, should be accurately precisionized in working position and rigidly held so that looseness or free-' dom of fit that may exist in order to permit it to be freely shifted during adjustment, shall be suppressed or taken up, the continued opera tion of the mechanism or machine necessitating, of course, that each adjusted member be" ultimately returned to its normal or inoperative position.

The present invention is directed to the provision of parts and devices so related and organized as to enable these results to be accomplished with facility and in such a manhoras to render the work performed by the adjusted member of a highly satisfactory nature. Y

Ina mechanism embodying my present invention, means will therefore ordinarily ex i 1st for adjusting the adjustable members un- Q-til the select-ed member shall have attained at least approximately the predetermined position requisite for it to performthe worlg for which it is designed, each such member being, moreover, so constructed and related f5 Ttli guide surfaces." by whichfits adjusting movement is determined as to freely permit such motion to be imparted to it; combined with theadjustable members and cooperative with each when the same shall have thusbeen shifted and is about to. erform its work, there is a device or means or giving it its final, recise position and for firmly and rigidly hdlding itin such precisionized position. a j

'I have set forth in the drawings attached to the present specification an embodiment of the present mechanism, and in these drawings, Figure 1 is a verticalv longitudinal section illustrating such embodiment, the plane of thesection coinciding with the axis of the carrier upon which the plurality of adjustable work-performing members are mounted, and which plane in this instance extends transversely to the axis of the main operating. shaft. Fig. 2 is a similar sectional view, the plane of this section, however, being at right angles to the plane yielding the section of Fig. 1 and that portion of the mechanism to the left of the plane of the section being viewed. Fig. 3 is aplan view, a portion of the inclosing casing being omitted for the purpose of clearly showing Parts lying beneath. Fig. 4 is a'se'ction on a plane transwhich a member is capable of a shiftingmovement for the purpose of bringing it into a predetermined position by reason of its being so related to'the guide faces which de- 'termine the characterof such shifting'movement as to enable it to be freely moved therealong and which member when so-shifted to approximately "its final position, is thereu on advantageously accura'tel precisionize as to position and rigidly" he dduring such pe v riod as the member performs its work. Such conditions and requirements prevail in many classes of typographic 'machines, and I have tical operative machine, it is contemplated that such a de ree of engineering and constructive skill as all be employed as to produce a proportion of parts and character of connections adequate to transmit the necessary forces and to create the necessary rigidity and precision. The exercise of such skill on the part of the designer and constructor to meet various conditions may therefore result in a mechanism the details of cona discrimination struction of which differ from those illustrated in the drawings hereto attached, which are accordingly to be taken in the sense of being illustrative only of these particular matters;

The various operative parts comprised in the mechanism will be mounted upon a suitable supporting fixture or fixtures of such shape and pro ortion as are determined, to a large extent, y the particular machine 'or mechanism inw ose construction and organization an embodiment of the present invention enters.- In the present illustrated embodiment, the support aforesaid is afforded by a frame or casing, designated in a general way by 1. In the present embodiment also, a plurality of adjustable members are indicated, such members being inthe nature of typographic im ressors, designated without y 2. These impressors are furthermore mounted upon slides such as 3, rendering the impressors adjustable. Any one of these slides and hence impressors may be brought in line. with the predetermined point hereinafter referred to as the working point; to enable this to be effected, the slides may be mounted upon a shiftable carrier, and while such carrierfmay obviously be of various forms and susceptible of a variety of movements in order to shift a given slide from a position out of alinement with the working point to a position inalinement therewith, I have for simplicity of construction represented a carrier, designated by, 4, the same being rotative about an axis,, de fined by the .carrier-supporting shaft 5, i'one of whose'reduced shoulder-forming ends 6 is mounted in a bearing'sup orted by a crossbar 7 of the casing 1; t e other reduced shoulder-forming end 8 of the shaft, rotates in a bearing supported by an overhanging arm 9 affixed to the frame or casing.

I have chosen to illustrate my invention as embodied in a mechanism in which an intermittent movement is imparted to the slide carrier, this latter being advanced at each step through an angular distancesuch that the slides are brought successively in line with the working point. When a slide shall have been so positioned and before'the carrier is advanced through the next angular movement, mechanism becomes operative to shift the said positioned slide and carry the impressor thereon toward its predetermined or working position, whereupon the slide, and hence its imprcssor, is caused to be accurately precisionized in position and the slide to be fixedly held in engagement with its guide, thus rendering the adjustable member, that is the impressor on the shifted slide, rigid, while the impressor is subjected to the various forces and stresses incident to its working. I have deemed such a mechanism so c onstructed and so operative, suffition, since obviously the invention is susceptible of application to a great variety of machines or mechanisms and in which the carrier isso shifted as to bring the adjustable members in line with the working point in other sequences than a consecutive one corresponding to the consecutive disposition of the members upon the carrier. And again, in point of time the consecutive periods consumed in replacing the adjustable member at theworking point by others may be widely, as respects relative duration, different from those occupied in such substitution during the operation of the present simple mec hanism. Proceeding, however, to adetailed descri tion of the mechanism'as it is illustrated in t e drawings attached to the present specification, the intermittent motion of the car rier 4 is effected from a main'shaft 10 assumed to be capable of continuous rotation froma suitable source of power (not shown) in driving connection with a pulley 11 on the main shaft. interposed between the shaft .5 of the carrier and the main shaft 10, is an inshaft with which meshes a companion gear 13 mounted on a shaft 14 j ournaled in bfiillv ings in'the sides of the frame, and having mounted on it a star wheel such as 15. (lollars such as 16 may obviously be affixed to both the shafts 1.0 and 14 at the proper points to confine such shafts to their proper rotary movement. The actuator adapt ed to engage with the star wheel 15 is in this in stance in the nature of an anti-friction roller 17, mounted u 011 an arm 18, extending from the main s aft 10 and which roller is so related to the star wheel as to impinge other, the result obviously being, assuming that the shaft 1.0 is continuously rota-ting, an intermittent movement of the shaft i-t and hence of the carrier 4. There being in this 1 instance, five slides upon the carrier-,tlre star Wheel 15 will also have five points or arms to effect, at the close of each step-by-step termediate transmitting connection comprfs Y mg a' spiral gear 12, attached to the carrier v cient to disclose the features of the invenagainst the arms of such wheel one after an- Iii movement of the carrier, the. shifting of the l mit the final movement of the link to take slides thereon one after another into line with the working point.

Each slide 3 1s movable'in line with the axis of the carrier being situated in a correspondin guideway 19 therein. The crosssectiona form of each slideis such, with relation-to its guideway, that the slide is readily and freely'movable lengthwise of the guideway save at such-times as the slide shall, by

an ex'traneously a plied pressure, be accu-- rately positioned precisionized) and forced into firmer engagement with the faces of the guideways. While the application of the present invention is not limited to any particular construction or relation of contacting faces of the slide and the guideway in which it is mounted, I may, in order to obtain the foregoing results, form each slide with a pair of longitudinal laterally convergent faces such as 20, 20, adapted to bear against correspondingly inclined faces adjacent to the mouth of the guidewayand a pair of substantially parallel faces such as 21, 21, adapted to bear against corresponding faces adjacent to the base of the guideway. Sufiice it here to; say, in further description of the illustrated slide construction, that each slide is providedwith a longitudinal projecting rib such as 22, which enters a corresponding channel in the guideway and revents the slide from dropping out latera ly from the guideway.

The features of construction of adjustable working members, such as thepresent slides constitute, are not claimed herein, the same constituting the subject-matter of another application filed by me on July 10, 1902 Serial No. 115,010.

Immediately upon the arrival of a slide in line with the working point ('which in this case is at the rear of the machine), means will engage with the slide to effect its longitudiadjustment. The meansfor accomplishmg such shiftlng movement is, in this case, in

the nature of an arm 23having a socket 24 at its free end adapted to engage with a pin or projection 25 extending laterally from the slide. The arm'23 is swung inward to enga e the socket therein with the pin on the '3 slide throu h theihstrumentality of a cam 26 affixed to the driving shaft 10, and the cam is operative to actuate thearm through a link 27 upon which is mounted an anti-friction roller 28 a ainst which the'cam is adapted to bear. T' at. end of the link 27 which is adjacent the driving shaft, is bifurcated and embraces the shaft whereby the end of the link is sup orted and guided, While the op 0- site end 0 the link is pivotally connected to an arm 29 functionin .in a manner that will presently be adverte to'in detail.

The longitudinal movement of the link is transmitted to the sooketed arm 23, through Ii eans preferably so constructed as to per Which is adapted to bear against the contact face of an arm,31 extending from a shaft 32 journaledin a-bearing 33 at the upper portion of the frame and a, bearing 34 in a bracket 35 constituting a fixture of the framing. To this shaft 32 the aforesaid arm 23 is likewise aflixed, and hence, when the link is shifted forward-in the direction of the arrow 71 in Fig. 3, the shoulder 30 forces the arm 31 to therear and causes the arm 23 to advance and engage its socket with the pin on the slide. A spring such as 36 may be utilized for insuring contact between the shoulder and the contact face of the arm 31, and hence assures the impart action of a definite amount of-movement to the arm 23 at each rotation of the cam 26. Assuming now that the pin on the slide alined with the working point has engaged with the socket in the arm 23, the slide is now ready to be shifted in its guideways to bring the impression device thereon to the working point. This is accomplished, in the organization disclosed, by lifting the arm 23-, thus carrying the slide longitudinally of the guideway in which it is mounted. This lifting of the arm 23, and consequently of the arm 31 and the shaft 32 to which the two arms are attached, may be efiectedthrough a suitable cam device. In the present instance the reciprocation of the mentioned arts simultaneously with which occurs the shifting of the alined slide to bring the impressor thereon to the working point and to then return such slide to its normalv position, is accomplished by a two-cam actuator, the cams embodied in which'are of such confi uration as to not-only positively move the side in each direction but also during such movement-and while the slide remains at rest in its two extreme positions, to'lock 4 the slide from motion other than that which is proper that it shall have. The two cams comprised in the two-cam device are designated, respectively, by 37 and '38 and they serve to actuate a rock shaft 39 journaled in bearings 40, 40, by means of rock arms 41, 42, secured to the rock shaft and each having mounted upon it an anti-friction roller, that u on the rock arm 41 being designated by 43 a apted to cooperate with the ;cam37, and that upon the rock arm 42 by 44 adapted to coo crate with the cam 38.

he rocking motion of the rock shaft 39 is effective to reciprocate the shaft 32 and,- the par s connected to it through a rock lever 45 (here'shown as a continuation of the rock arm 41). This rock lever 45 is bifu cated at its free end and embraces a bl" ck 46 20 ing one of these temporary periods of rest, to

' being the construction, it is plain, assuming the cams 37 and 38 to be of the proper contour and properly related to each other, that a single rotation of the driving shaft is ef-' fective to cause an upward movement of the shaft 32 and subsequently the return thereof to its normal or lowermost position. The cams 37 and 38 are moreover of such configuration as to cause a dwell, representing a portion of the period consumedin' each single rotation of the main driving shaft, when the shaft 32 is in both extreme positions of its reciprocatory movement as aforesaid. Dur- Wit, the one corresponding to that position of the shaft 32 in which the same 18 at its lowermost position, .the engagement of the socket on the. arm 23 with the pin on thealined slide will be efiected, and at the other temporary cessation of movement of the slide, the adjustable member, that is the impressor on the slide, will be positioned approximately at the working point preceding the performance of the work which it is contemplated that it shall do. Prior to the execution of such work, however, it is desirable in practice, in order that satisfactory results shall be attained, that an adjustable member [or impressor should be more precisely located or precisionized in its definite working position than by the mere shiftingof a slide which must necessarily be slidably fitted to its ways to permit it to be slid'therealong and hence liable to change its position when pressure is brought to bear on the impressor thereonmounted; when working, it should moreover be as rigid in its working osition as may be in order to eliminate the i 1 effects incident to any looseness which it might have by reason of the fact that the slide must be so constructed and related to its guideways as to permit it to be freely slid therealong.

In order to accurately precisioni'ze and fixedly maintain the. adjustable member in its working position, means are provided constituting one feature of the present invention, for firmly pressing the slides upon which the impressors are carried against the respective guideways in which theyfare mounted. This pressure is exerted, in the particular construction set forth, against the arm 23 when the same shall have been elevated to shift the impressor into :the working point, and I utilize for exerting the such pressure, a presser such as 52, in this case in the nature of a resser arm, secured to a shaft 53 jour- Scaled in abearing 54 in the aforesaid bracket eoasze 35 and a bearing 55 supported by the frame B. Collars such as 56, 56 secured to the shaft serve to prevent its longitudinal movement, while the angular movement thereof to force the arm 52 firmly against the arm 23 results from a longitudinal movement of the link 27 occurrin subsequent to that move ment thereof which engages the socketed arm 23 with the pin on the alined slide. It will be noticed that the cam 26 has a portion .57 of slightly larger radius than the portions of the working face of the cam immediately adjacent. It is this ortion of larger radius that continues the ongitudinal movement of the link to slightly turn the shaft 53 in its bearings. This angular movement of the shaft 53 takes place after the shaft 32 has been raised to bring the impressor more or less approximately into the working point; the parts are referably so proportioned that when the fina forward movement of the link takes place, the contact face of the armSl' will have been raised out of the/path of the shoulder 30 on the link and hence the pressure precisionizing the slide and forcing the same firmly against the faces of its guidewa'y will be exerted by the presser arm 52 directly against that portion of the arm 23 which is immediately adjacent to the location of the socket therein. It should here be stated that the width of the arm 23 where pressed against by the presser arm 52, is sufficient to preclude the disengagement of the two at any time and that the correct and certain action of the link 27is here-assured by a spring such as 58 which serves to force the cam roll 28 on the link toward its operating cam 26.

So far as the construction, organization and operation of a locating and precisionizing mechanism, such as has been hereinbefore described, is concerned, it is obviously not LOO restricted in its use or application to any particular mode or character of working which the adjustable members perform. I have,

by way of illustration, however, (such repre' sentation not being therefore in any sense a limitation) indicated a platen for cooperating in succession with the successively located.

and precisionizedimpressors. Inthe conventional representation thereof set, forth, the platen is designated by 70, the same being in the form of a roller mounted at the end of a rock arm. 59 secured to a. rock shaft 60 mounted in bearings 61, and operated by a cam 62 adapted to impinge against a camroll 63 mounted on a link 64'pivote5l to an arm 65 extending from the aforesaid-rock shaft 60; A spring 66 insures the proper cooperation of the cam 62 with the cam roll 63 and the op eration of the'cam is so timed with relation to the operation. of the other cams already described that the platen is caused to 006pcrate with each iinpressor when the same shall have arrived at the working point and the slide upon which the lmpressor 1s mount- I I of the slide whose d is pressed against the faces of its guideway. Means are also provided in the illustrated mechanism for holding the several slides in correct normal position in order that the socket upon thearm may'. en a c with the pin on a slide, when the slide site 1 have been brought into alinement with the working point. The means herein shown for this urpose rforms the further function of ock-ing a the slides from lengthwise movement in their guideways with the exception in 25 may be at. any iven time opposite t e socket in the arm 23.

his means 18 in the nature of a locking groove,-such as 67 the plane of whioh'is normal to the axis of the slide carrier and the groo'vebeing in such position that the ins or rojections 68 on the respective sli es are nee to travel through the groove when the slides are in their normal position. This groove '67 is in this instance formed in an annular fixture 69, here shown as detachably secured to the frame 1, the fixture being cut away at such a oint as to enable'the lifted 25 arm 23 to shift t e alined slide lengthwise of its fguideway and locate the adjustable impressor at or near the working oint. The configuration of the cams andt eir relative timing are so related as to cause the return of the parts afteractuation, in proper order, to their normal sitions, following which a recurrence"of t e operations as hereinbefore described takes place.

Concisely the operation of a mechanism such as has been described takes-place as'follows: Assuming the driving shaft 10 to be in rotation and that an intermittent movement is imparted through the star' wheel 15 and engaging s iral ears 12 and 13 toth e carrier 4, each sli e being brought in turn in alinement with the working point, the first opera tion occurrin when a slide shall have arrived thereat is the movement of the arm 23 inward to cause thesocket thereon to engage with the pin 25 onthe jslide, this resulting from the longitudinal movement of the link 27 imparted to it from the cam 26 which forces the shoulder 30 against the contact face of the arm 31; [Further movement'of the driving shaft brings into-action that cam of the pair 37, 38 which serves to raise the shaft 32 and hence thearm 23 and thereby locate the impression device 2 at the working and rigidly holding them in .th'e'predetermined position correspondingto the working posi tion of the impressor. The working of the I claim was the cam-shaft for pressing adjustable device or member (impressor) now takes place, that is to say, in this case the platen is rocked against the same by the operation of the cam 62 against the cam roll 63. The parts now return to their former position, the presser bar 52 first releasing the arm-23 through the action of the spring 58 upon the disengagement of the part 5701 the [cam 26 from the cam roll 20; after this the shaft 32 is caused to descend, the slide to be. drawn downward and the shoulder 30 on the link 27 is rengaged with the contact end of the arm 31. The parts are now ready for passing through another cycle of movements as before.
