MECHANICAL MOVEMENT.

Application filed June 2, 1902.

or character of movement imparted to it. in-

sufficient or incapable to effect that for which such member may be constructed and capable and which by its organization it is adapted to accomplish when fully functioned.

The present mechanical movement is susceptible of application to various purposes and in combination with various elements. Thus, for instance, it may be employed in connection with a selective mechanism em-' bodying a so called key operative device, serving when properly connected with and related to the latter to complete movements or operations which the several keys are designed to control or bring about even though the movement imparted to anyone of the keys of the key-operative mechanism be merely an initial movement and therefore less in extent than necessary to cause the key to effect its full designed function.

In carrying my present improvements into effect- I have in the particular embodiment set forth in the accompanying drawings,

and chosen by way of illustrating an application of the invention, represented so much of a key-operative mechanism as sufiices to a full understanding of theinvention, and have illustrated as combined with such mechanism various details and mechanical elements so organized that the first or initial movement of an actuated key of the keyoperative mechanism results in such an op eration of associated elements that the motion initially imparted from the key suffices to move an actuatable member through a distance equal to that which the key upon its full movement mi ht serve to accomplish.

In the illustrated mechanical movement, the elements combined with the key-operative mechanism comprise a'power-driven elementthe transmission of' motion from which isrestrained Specification of Letters Patent.

during such time as the keys of the key-operative mechanism are in their normal posi tions but which restraint is released upon the initial actuation of any key, whereupon during the subsequent cycle of movements of the power-driven element the latter through suitable devices completes that motion which the actuated key tends to accomplish.

In my copending" application Serial Number 131,004, filed Nov; 12, 1902,.and allowed May 20, 1907, I have described and claimed a mechanical movement; therein stated'to be distinguished from that set up herein by reason of the fact that the organization and construction of the devices and elements of the present mechanical movement are such that the movement or movements, initiated by the depression of a key lever and subsequently completed by the supplemental actuator, is repeated as long as the pressure for actuating it is maintained upon the key lever. The mechanical movement of my said copending application on the other hand is so organized as to complete one and only one cycle of operations initiated by the actuation of the key lever, even though the actuating pressure upon such lever be maintained throughout such cycle of movements and afterward. That is to say while the kinematic relation exhibited in the mechanical movement illustrated in my present application is such asto cause a repetition of movement as long as the key, lever remains depressed. The relation and construction illustratedin the movement of my said copending application accomplishes under the same conditions but one complete operation, and in order, therefore, in this latter case to repeat such operation it is necessary to first release the key lever and permit its free end to raise and afterward to again depress such end. Although this line is drawn in said other case to distinguish its scope, yet certain of the illustrated structure, properly claimable herein, is not limited in its function to a structure having a capability ofrepeating its cycle of movements during the continued depression of a lever;

In the drawings accompanying the pres forth such an embo iment, Figure l is part y an elevational view and partly a sectional view illustrating a portion of one of thekeysof a key-operastructive skill shall be employed as to pro-- tive mechanism with which there is organized a power-driven shaft and intermediate mechanism serving to restrain the motion derivable from such power-driven shaft until by the actuation of the key such restraint is withdrawn and the power-driven shaft becomes operative to complete that motion which the actuated key has inaugurated and which it tends to complete; Fig.2 is an elevational view from the rear of the 1118011311- ism, that is looking from the right-hand side in Fig. l; Fig. 3 is a view similar to Fig. 1, but shows the various parts in theiposition assumed by them immediately subsequent to the initial movement of the actuated key of thekey-operative mechanism, which movement serves to release the power-driven element or shaft. Fig. 4 shows the parts in a position assumed by them at a more ad-- vanced stage, resulting from the motion imparted from the powendriven shaft. Fig. 5 is an elevational view of one of the actuatable members.whose.motion is initiated by.

the actuation of ,a key and completed through the instrumentality of the released power-driven shaft, this view showing devices associated with the actuatable member, whereby the same is compelled to move in a direction parallel to itself whether. the point of application of the force moving it be in line with its cent-er of resistance or whether such point of application be to one side or the other of such line. 3 a

Similar characters of reference designate corresponding parts in all figures.

The organization illustrated herein for the purpose of adequately disclosing the present invention is one in which the features of the latter are applied to a key-operative .mechanism, the performance of the function of any one of the keys embodied in which is thereby rendered in a sense independent of the fact whether any key be operated to the full extent necessary for producin that which the key is designed to accomp ish or whether the movement of a key as the result of the application of. the finger of the-operator is insufficient in itself to accomplish the designed result. In the practical use, therefore, of an organization of this character and embodying the invention it is suflicient in order to produce the result referable to any one of the keys of the mechanism that the proper key should be initially whereupon as the result of this initial movement further motion complementary of that initiated by the slightly depressed key is continued by other means from the powerdriven device of the mechanism. In the manufacture and assembling moreover of the various parts to form a complete and practical operative device it is contemplated that such a degree of engineering an condepressed,

duce a proportion of parts and character of connections adequate to transmit the necessary forces and 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 construction of which differ from those illustrated in, the drawings hereto attached, which are therefore to be taken in the sense of being illustrative only of these matters.

In the illustrated form of the members directly actuatable from or whos'e motion is controlled by the various actuators, being keys of the key-operative mechanism, they are'in the nature of slides B, mounted in suitable guideways in proper supports, here represented as cross-pieces 2, 2 extending between uprights 3, 3 erected upon a supporting base C. These various 'supporting members may evidently constitute in whole or in part, portions of the framing of the ment of the resent invention is applied. \Vhile I have in the present case, shown, but one of the members B in side elevation, and in edge view, two of the members, see Fig. 2, it is contem lated that there shall be ordinarily one 0 these members for each of the keys in the key-operative mechanism. I have furthermore lllustrated but one key-lever, marked K deeming such showing to be suflicient for a comprehension of the present invention, but it is likewise contemplated that any proper number of such levers shall be employed, depending upon the nature of the machine and the purpose for which the key-operative mechanism is employed. Each key-lever K has, in this instance, an upright portion 70, at its outer end surmounted by a suitably charactered finger-piece is, while intermediate the'end of each key-lever there extends .therethrough a proper fulcrum bar such as 4 supported in uprights 5 on the base 0. In its normal position eachkey-lever is held withits outer end elevated, a spring 6 key-lever will be suitably connected with that member B which it serves to actuate, a curved finger I) in this instance extending in the lane of the vibration of the leverand being ocated in a corresponding undercut curved slot forming a journal member 6' in the upper portion of the rear end of the keymachine or mechanism to which an embodi-' secured to the lever operating to elevate such from side to side of the mechanism. "Each lever. Freedom of pivotal movement, it is evident, results between the connected parts in a connection of this character.

If the 'outer end of a' hey-lever be depressed the corresponding actuatable member B will be elevated, and the parts are so related to each other that upon a full depression the member B will be moved a dis tance suflicient to enable it to accomplish the purpose for which it is designed. If, however, the outer end of the key-lever be depressed to a less extent than aforesaid the member B will be moved a proportionate part only of its full movement which may be insuflicient to enable it to attain the designed result; upon removing the finger from the key the actuated member B will then return idly with the key-lever to its normal position under the tension exerted by the returning spring 6 by reason of the fact that the member B in the form of connection between the two illustrated is both pushed and pulled by the key-lever.

A particular feature of the present invention relates to means in the nature of a sup-' lemental actuator cooperative with the key ever whereby the operation of each member B, that is, its movement in the direction in which the connected key-lever when actuated tends to move it, may be continued and by such supplemental actuator completed and it be moved through its entire predetermined path of movement even though the level" be .not fully functioned and to an extent less than suffices to shift it from one end of such In accordance with the present improve- 'ments 1' utilize 'a power driven element which is held from accomplishing its 'intended pupose until the inner end of a keylever; shall have been elevated to a more or less extent, whereupon such power-driven d'evicejisj released and connecting devices j'become' operative to complete the move ment initiated by the ascent of the inner end of the lever} In a convenient'form thereof, this power-driven device comprises a shaft such as 9 mounted in suitable bearings', which in this instance are provided in theaforesaid uprights 3 and 3', an outboard gbearing being also provided in a bracket 10 secured'to the upright 5Tv In the present embodiment this shaft9 is. normally at rest but is capable of being set in motion through the operation of a suitable clutch device. In a convenientform' of the latter, and as shown herein, the shaft is frictionally driven, a'pu'lley or other driver 11 being loosely mounted thereon and being driven-from'-asuitable source of power, not

7 shown. -Suit-ablefriction rings 12,..1'2 are pressed into 'closefrictional contact withthe 'opppsitej radial faces of the pulley 11, "by

washer-likeca'sings 13' and :13 respectively, h -i eat- 51 1 s s w d the shaft 9, while the latter is splined thereto, see the spline 13, to permit the casing to move longitudinally of the shaft while compelling the former to rotate with it, thereby enabling the friction to be regulated, which in this construction may be done by means of the tension exerted by a spring 14, controlled by an adjustable clamping nut 15 screwed onto the threaded end of the shaft. If the shaft 9 is not restrained from movement it will rotate with the pulley 11 during the rotation of the latter. Normally, however, the motion of the shaft is prevented even though the pulley be ro-- tated, through the'instrumentality of a stop arm 15 extending from theshaft and with which engages an escapement in the nature of a forked arm or detent 16 whose hub portion 16 is pivotally mounted upon a stud 17 extending from the upright 3. As long as the arm 15 is seated in the recess in the detent 16 no motion of the shaft 9 will ensue. Release of the stop arm from the detent is effected during the first portion of the movement of an actuated key through the instrumentality of suitable connecting mechanism, a form and construction of which will now be described. Each member B is pro'videdfwith 'a'shoulder 17, all of which are substantially in the same plane crosswise of the series of members B. Againstthese shoulders is urged a cross-rail or bar 18' sea cured to the ends of one or more arms 19 extending from a rock shaft 20 suitably mounted in the uprights 3, 3. Inthis'instance the mounting comprises pivot pins '20,20 extendin g inwardly from the uprights and secured in look nuts 20 20". A'flixed to and "extending from the aforesaid shaft 20 is astop' arm 21 the path of whose outer operative end intersects the position proper path of movement of'the corresponding end of an arm" 22 extending from the aforesaid hub'portion 16 of the detent 16. The relation and organization of the parts is such that'when the key-levers are in their normal position the end of the arm 21 will be interposed in the .path of the arm 22 with the two in contact and the arm 15 seated in the recess of the forked detent 16, thus preventing the rotation of the'shaft'9 in the direction of the arrow in Fig. 1. Upon a slight movement of a member B, however, the cross-bar 18 will be lifted, withdrawing the end of the arm 21 from contact with the arm 22 and throughthe action of a spring 23 which encircles the stud 17 and is properly tensioned, the detent 16 will be withdrawn from engagement with the arm-15. The shaft '9 now being released, motion will 'there'upon'be imparted to it from the ro- Jtating driving pulley 11. The rotating shaft serve'sfto continue the motion of the actuated member B through some suitable-mechanism, a simple form of which is illustrated I in the .drawings attached to the present specification, and will now be described. Extending from side to side and mounted in the uprights 3, 3 in like manner to the shaft is a rock shaft 24" connected by means of an arm 25 and a connecting rod 26 with acrank 27 on the shaft 9; thus during each full rotation of the shaft 9 an oscillation will be imparted to the rock shaft 24.

A cross-bar or plate 28 at the outer ends of arms 28, 28 extending from the rock shaft '24 is adapted to coiiperate with the key-lever as follows Each key-lever K at its rearward end is provided with a projection 29 above which When the lever is in its normal position the aforesaid bar or plate 28 is .adapted to freely play when the oscillation of the shaft 24: occurs, and hence in such a position of the levers the bar is inoperative to engage with anyone of the projections. When, however, the inner end ofa key-lever has been elevated to a slight extent, the

aforesaid projection on the lever will be brought into a position in which its under surface becomes the surface with which the working edge of the bar contacts, and as the bar moves forward it becomes effective to elevate the lever as the result of. such engagement. During this movement, moreover, (the relation of the parts being such that this result is effected) the bar will freely. play across the upper surfaces of the extensions of those levers which have notspective key-levers and this supplemental actuator 28, I have provided means for positively causing the insertion of the stop arm 21 into the path of the arm 22, after the latter shall have been shifted against the tension of spring 23,from a position as indicated in Fig. v3 to a position as indicated in v Fig. l by means such as a cam 30 on the on the stud 17".

shaft 9 with the periphery of which engages a projecting finger or cam block 31 extend ing from an arm 31 fixed relatively to the aforesaid hub portion 16 rotatably mounted This means for positively inserting the stop arm'2l comprises a link .32 pivoted to an arm 32 extending from the aforesaid shaft 24 and whose bifurcated end portion 32" embraces a pin 32 extending laterally from the arm 21'. During the movement of the supplemental "actuator 28 toward the key-levers, the link 32 changes,

somewhat, its position as indicated inFig.

1, the pin 32" sliding lengthwise of the slot in the bifurcated portion of the link. .On

the return movement, however, the pin contacting with the bottom of the slot is urged forward and the arm 21 caused to assume a position in which the arm 22 under the impulse of the spring 23 and as the cam block 31 drops down at the let-off edge 30 of the cammay impinge againstit andbelocked from movement. In this locked position of the arm 22, the detent 16 is interposed in'the path of the stop arm 15 and the shaft 9 is stopped from rotation although this latter action does not occur until the bottom of the slot in the link end is somewhat withdrawn from the pin 32, thus leaving the arm 21 free to be tilted upon'the next actuation of a key-lever to an extent suflicient to permit the disengagement of the arm from the arm 22. A spring 20 is also shown for insuring the contact of the cross-bar 18 with the shoulders 17 on the members B.

Evidently so far as concerns the utilization of the movements of the members B, the movement of'ea'ch such member may be applied for any particular purpose required by the mechanism to which the mechanical movement is applied and to the accomplish-- ment of which it is adapted. For the sake of illustration I have set forth herein such members B as being operative to effect the movement of transmitting members one or more of which maybe actuatable from any particular one of the ,members B. Such transmitting members are indicated by R, and they are mounted to move in the line of movement imparted to the members B. Any desired number of the members It may be adapted to be moved from any particular member B. For effecting this each member B may have one or more projections 7' adapted to contact with one or more of the members R, the relation as to number and position existing between the members R actuated, depending upon the position and size of the projections 0. As organized in this instance, it may happen that contact may be made between some of-the members R and a member B at one side or the other of the'center of resistance to movement of such latter member, and hence were not these members properly mountedthe tendency would be to tip the same upon the application of the moving force. In order, therefore, to maintain the rectilinear char- 'acter of this movement and permit the same to accomplish with equal facility whatever the point of application of the force I have provided a construction comprising a pair of angle levers 33, 33' fulcrumed to fulcrum bars 33", -33" extending between lugs 33 ..on the uprights 3, 3, each lever having oneof its arms pivoted to a member R, while the other arms of each air of levers 'are 'pivotally connected toget er by a link 34.

the application of the force exerted by the moving member B use of any partlcular device or mechanism or species of the same I may utillze the movement of the members R to set pins such as a: upon a jacquard belt X, an example of such abelt being set forth in my Patents Nos. 573,621, 573,622 and 573,623, granted Dec. 22, 1896. lVheu the application of the movement i for this purpose each. of the members R will be usually provided with an actuator portion such as 35 having a beveled or cam-like edgendapted to cooperate with a corresponding row of settable pins on the belt. v An embodiment of a mechanical movement such as has been hereinbefore described operates substantially in the following manner: Assuming the parts to be in the position indicated in Fig. 1, upon the depression of the outer end of a key-lever K the inner end will rise, and ass. result of the initial movement of the connected member B the cross-bar 18 will be-elevated. thus causing the withdrawal of'the arm 21- from contact with the stop arm 22. Then the cam block 31 dropsdown and into contact with that portion of the cam 80 of the smallest radius the spring 23 will withdraw the detent 16' from arm 15 permitting the rotation of the, shaft 9 from the rotating driving pulley 11. Through the action of.

the crank 27 and the connecting rod 26 the shaft 24: is turn ed in its bearings, thus bringing the cross-rail or supplemental actuator 28 under-the projection 29 of the actuated key-lever and as the shaft continues to turn in the same direction the inner end of the lever'is carried upward, while at the same time such cross-rail plays in the space above the projections of'those key-levers which are not actuated. The shaft 24 is, rocked in its bearings to a sutficient extent to elevate the inner end of the actuated key-lever to an amount suiiicient to fully accomplish the play of the connected member B in its bearings. This member-will actuate, as aforesaid, one'or more of the members R according to the number and configuration of the projections 1" thereupon, and these members R in their'turn will through their actuator portions 35 set up corresponding pins X upon the jacquard belt X.

During the forward rotary movement of the shaft 9 the hub 16 carrying the cam block 31, the arm 22 and the detent 16 will be gradually rocked against the resistance of the spring 23 as the block travels up the surface of the cam 30. Before, however, the block reaches the let-off edge 30 of the cam the motion of the shaft 24 will have been reversed the link 32 and causing the arm 21 to extend into the path of the arm 22. lVhen the block 31 slips off the let-off edge of the cam and the spring 23 becomes operative to swing the arm 22, this arm and the various parts associated therewith will be locked by the arm 21. A slight relatively reverse movement of the shaft 24 now-ensues, witlr drawing the bottom of the slot in the bifurcated portion of the link 32 from the pin 32",

whereupon the arm 15 engages with the detent l6 and the parts are brought to rest.
