FEED MECHANISM.

SPECIFICATION forming part of Letters Patent No. 597,566, dated January 18, 1898. Application iiled Aug-ust 29, 1896. Serial No. 60t,273. (No model.)

To all whom 'it may concern,.-

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Feed Mechanisms, of which the following is a specification.

This invention relates to feed mechanism Ygenerally and especially to variable-feed mechanism, which may be used in connection with type-writing, matrix, and analogous machines lin which an actuated member or feed member normally in inoperative relation With suitable actuating mechanism may be intermittingly brought into engagement with a feed-actuator and moved a determined distance thereby. f

Itis one of the main objects of my present invention to provide in connection with such a feed mem ber a pl urality of feed-actuators,each of which will be operative to impart to the feed member a feed movement independently of the operation of the other actuators of the group or series and to give to such actuators variable feed values, so that any desired one of a determined plurality of feed movements may be imparted to the feed member selectively, and any desired number of like or variable feed movements of the feed member may be effected in any desired order or in any preferred combination. It is also my purpose to impart these variable-feed movements to the feed member automatically and to effect the indication of the different feed values selectively in a predetermined order; and to the end that this may be done my invention also contemplates the control of a feed mechanism and especially of a feed mechanism such as that described in this specification by means of a jacquard or jacquard mechanism having suitable indications recorded thereon indicating', respectively, the selection of a determined succession or combination of feed movements to be imparted to the feed member successively in the order in which they appear on such jacquard.

In the drawings accompanying and forming part of this specification, Figure l is a sectional side elevation, looking from the right hand in Fig. 2, of a feed mechanism embodying my present invention. Fig. 2 is a sectional plan of the same. Fig. 3 is a vertical transverse section ofthe same, the section being taken in line 3 3, Fig. l. Fig. is a rear elevation of the left-hand end of the feed mechanism, as seen in Fig. 2, and illustrates the parts in their normal or ineffective positions. Fig. Sis av similar view showing the parts in their effective positions for imparting a feed movement to the feed member of the mechanism and to the parts controlled by such feed movement. Fig. G is a longitudinal vertical section of the feed mechanism, the section being taken in line 6 6, Fig. 2, looking in the direction of the arrow and illustrating the feed member and cooperative parts in their ineffective positions. Fig. 7 is a similar view illustrating the feeding operation. Fig. S is a detail showing the variablefeed cams carried by the main driving-shaft. Figs. 9 and l0 are detail sectional side elevations of the jacquard-controlled indicating mechanism and its cooperative devices and illustrate the parts in successive positions for imparting a feed-indicating movement to the indicatin g-bar hereinafter described. Fig. 1l

is a detail illustratin g the jacquard -controlled the feed mechanism in which my present in-v vention is embodied. That shown herein is illustrated having a base-plate 2, from the opposite sides of which rise uprights or supports 3 and 4 and an intermediate arched support i similar t0 that at e', in which a main drivingshaft S is shown mounted for rotation and carrying at its left-hand end a main drivingwheel D, which, itV should be understood, will be normally continuously operated.

The feed-actuators controlling the movements of the feed member are represented in the present case fixed on a sleeve or rotary cylindrical carrier l0, secured to the shaft S for rotation therewith, and these actuators are illustrated herein as a plurality of feedcams preferably axially alined and having different axial positions, said cams being shown as four in number and being designated, respectively, by c, c', c, and d. Each cam in the present case is also represented IOO l having the termini of its periphery merged in the periphery of the rotary carrier 10, so that the feed member when actuated by such cam may start from its normal position and return thereto by a gradual movement, the cams thus serving positively to control the movement of the feed member from the beginning to the end of its operation and to prevent jarring and uneven movement, which migh't tend to impair the accuracy of the feed. The feed member Which these cams are designed to actuate is represented mounted on a carrier 5, supported in the supports 3 and 4 and parallel with the shaft S, this feed member being designated in a general Way by F and being shown having a tubular portion or sleeve G, having secured thereto at one side thereof a feed-segment 7 and at the opposite side thereof a feed-controlling arm 8, carrying an antifriction-roll 9, normally in contact With the periphery of the sleeve 10 and adapted when shifted axially thereof to be brought opposite one of the feed-cams. This feed member is illustrated automatically retrogressive or reactive to its normal position (seen in Fig. 3) with the left-hand end of the sleeve 6 contiguous to the upright 3, a strong spiral spring being represented at 100, surrounding the carrier 5 between the inner end of said sleeve and the partition or upright 4. The sleeve 6 is also shown' having integral therewith at the rear side thereof (see Figs. 4 and 5) an axial series of stops, one for each cam, designated, respectively, by s, s', s", and 3"', each of these stops being adapted to cooperate With a suitable locking device or detent, so that the feed member may be looked in its Working position when its antifrictionroll is brought into line with any selected cam. This feed-memberdetent is designated in a general Way by CZ and is shown as an oscillatory member mounted on a stud l2, secured to the upright 4 and having at the outer end of its short arm 13 a locking-finger 13', which constitutes the detent proper, and at the outer end of its long arm, which is designated by 14, an autifriction-roll 14', adapted to travel on the periphery of' a cam 15, sec'ured to the main driving-shaft S. (See Fig. 6.) For the purpose of normally holding the antifriction-roll in contact Wit-l1 the cam a strong helical spring is represented at 16 secured at one end to the arm 14 and at its opposite end to the base of the apparatus.

The movement of the feed-segment 7 may be utilized to operate a driven device or mechanism of any suitable construction or organization. In the presentcase I have represented this feed-segment as meshing with a corresponding segment 17', which is illustrated as a wide-faced segment forming part of a sleeve l7,.loosely mounted upon a driving-shaft, which is represented at S' as carried for rotation in suitable bearings in the uprights 3 and 4, this driven shaft being also shown as a feed-screw, the outer end of which is illustrated passed through and supported in a traveler 20, suitably guided for movement along a transverse frame member 21 at the rear of the apparatus. (See Figs. l and The feed-screw S' is represented, having the usual spiral v groove, with the Walls of which the inner end of a spring-pressed detent or locking-bolt 22 is represented engaging in the usual manner for causing the advance of the traveler 2O and for permitting the return of the same to its initial position on the Withdrawal of the detent from engagement With the Walls of said groove. It should be understood that this movement of the traveler and feed-screw may be utilized in anysuitable manner, and for this reason only so much of said feed-screw and its coperative parts is shown as is deemed necessary for a clear understanding of the operation. The sleeve 17 is also represented having a paWl-carrying arm 17", supporting a pawl 23, normally held in the usual manner by means of a light spring in engagement with the teeth of a ratchet-Wheel 24, xed on the-shaft S'. For the purpose of returning the sleeve 17 and its segment to their normal positions after a feed movement has been imparted thereto by the feed member 7 a strong spring is shown at 49 secured at one of its ends to a pin or stud 17"', fixed on the sleeve, and at its other end to the upright 3. (See Figs. 3, 6, and 7.)

As has been hereinbefore stated, I propose to control the several feed movements of the variablefeed mechanism from a jacquard, and a jacquard mechanism suitable for this purpose is illustrated at the forward righthand side of the apparatus.

The jacquard which I have illustrated herein as an endless belt or traveler has on the outer side thereof a plurality or circuit of jacquard-pins or indicating-actuators, such as p,disposed, preferably,in transversely-separated longitudinal series, as shown in Fig. 2, and spaced equidistantly longitudinally of the jacquard, as will be evident by reference to Fig. 1. This endless jacquard may be mounted in any suitable manner, it being shown in the present case as supported on a pair of

rotary cylinders

25 and 26, carried for rotation in the bearings of

suitable uprights

27 and 28, rising from the base-plate 2. The cylinder 25 is also illustrated, carrying for movement in unison therewith a driving ratchet-Wheel 29, which is represented deriving its movement from the main shaft S, the driving connections for this purpose being shown as a link 30, loosely mounted at one end on the shaft of the cylinder 25 and having at its opposite end an antifriction-roll 30', a cam 3l, secured to the shaft S and cooperating With said antifriction-roll to oscillate the link 30, and a spring-pressed paWl 32, carried by said link and oscillatory therewith for rotating the ratchet-Wheel 29 the space of one tooth on each rotation of the shaft S.

A stop-pawl is shown at 3S for preventing return movement of the ratchet-Wheel, and a strong spring is also illustrated at 34, secured at one end to the link 30 and at its opposite end to the support 4' for retaining the antifriction-roll 30 in contact with the cam 3l.

The jacquard J is represented driven in the present case by sprocket-teeth 35, engaging the Walls of corresponding drive openings or sockets 3G in the inner side of the belt, and it will be evident that at each rotation ofthe shaft .S this jacquard will be advanced a step by the ratchet-wheel 29, the interval being equal to the distance between any pair of adjacent jacquard-pins.

The indications shown on the jacquard may be taken oft by any suitable device. In the present case the jacquard-pins are illustrated as operative for shitting from a normal unset position a plurality of indicator actuators or tumblers, such as t, which are represented in the drawin gs carried for oscillation on a frame A, secured to an oscillatory carrier-shaft 37, carried in bearings in the forward ends of the supports 4 and 4. This frame is shown supporting at its rear end a tumbler-carrier bar 38, having parallel kerts forming alined tumbler-separatin g members, which have also registering apertures for the reception of a tumbler-carrier, such as 39, on which the tumblers are illustrated supported. (See Fig. il.) at the ends of the kerfs in the tumblercarrier bar dii/*erging stop-Walls are shown at 38 and 3S" for limiting the movements of the tumblers. Said tumblers are disposed in such positions that they will be in the paths, respectively, of the respective longitudinal series of jacquard-pins, and each of these tumblers is represented having a depending` n`- ger 40 inclined toward the jacquard when in its norma-l position, so that when it is enga ged by one of the pins p t-he tumbler will be in the position shown in full lines at the right in Fig. 9. It should be understood that the tumblerseparating Walls are vcontiguous to the sides of the tumblers and exert suffi cient resistance to prevent movement of the tumblers until said tu mblers are positively actuated from one position to the other.

The tumblers just described constitute a plurality ofindependently-effective jacquardcontrolled actuators, each of which is operative selectively for actuating a feed-indicator, preferably in the form of a variable-feed indicator, having variable movements corresponding, respectively, to the respective variable feeds controlled by the feed-cams c, d, c, and c'". This indicator is designated in a general way by I, and is preferably in the form of a frame loosely mounted for oscilla` tion about the shaft 37, one side oi said frame beingshown in Fig. 2 mounted directly on the shaft, while the other is represented clamped to a sleeve 37', surrounding said shaft, this frame being illustrated carrying at its free end a transverse indicating-bar 42,' (sce'Fig. 11,) having a plurality of indicating` members or indicators, such as i, alined, re-

spectively, with the respective tumblers t and controlled, respectively, thereby. It will be noted by reference to Fig. 9 that these indicators 'i are out of the paths of movement of the respective tumblers when said tumblers are in their normal positions, but that When any one of the tumblers is moved toits set position the operating-linger thereof (shown at 4l) will lie in the path of its respective indicating member and engaging the same will actuate the indicator I and Will oscillate the indicator a distance proportionate to the feed which' it is desired to indicate.

It Will be obvious that the maximum and minimum feed movements will be controlled by the indicating members shown, respectively, at the left and right in Fig. l1.

ItA should also be stated here that the tumblers constitute indicator-actuators for the indicating members or indicators and hence for the frame I, the tumbler-carrying frame being normally continuously operated by the main driving-shaft S from a settable to a Working position, the shaft S being represented having 4thereon a cam 43 for this purpose. (See Fig. l.) The shaft 37 is also illustrated having a rock-arm 44 secured thereto and carrying at its free end an antifriction-roll 45 in contact with the periphery of the cam 43, (see Figs. l and 2,) so that When said cam is rotated the rock-arm 44 and the tumblercarrying frame Will be intermittently oscillated Afrom the position shown in Fig. l to that illustrated in dotted lines in Fig. 9, a strong retracting-spring being shown at 4G connect- 'roo ing said rock-arm and the base of the machine to thereby maintain the antitrictionroll in its proper Working position.

At the end of the shaft 37 opposite that at which the rock-arm 44 is carried I have illustrated at 47 a second rock-arm clamped to the sleeve 37', so as to move in unison With the indicators, and by means ot this rock-arm the movements of the indicators 'z'- are transmitted to t-he feed member for shifting the same longitudinally of the carrier on `which said vfeed member is mounted.

I have shown in the drawings (see Figs. 2 and 3) an overhang 4, forming part of the support 4 and having pivot-ally mounted thereon a feed-member shifter in the form of an angle-lever 4S, which is represented disposed transversely to the rock-arm 47 and having one of its arms 48 shaped to form a cam-surface cooperative with an an tifrictionroll 47', carried at the free end of the rockarm 47.' The other arm 48" of the angle-lever is shown engaging an antifriction-roll 6', carried by the sleeve (5 of the feed member F.

After the operation of the indicator I by one of the indicator actuators or tumblers t it is necessary to return said tumbler to its normal unset position in order that the tumbler which is to be selected by the next succeeding pin on the jacquard may operate Without interference from the tumbler already actuated. Hence I have illustrated at R resetting means suitable for restoring each being rassumed that the main driving-Wheely 4by the movement of the sleeve 6.

of the indicating actuators or tumblers to its normal unset position after operation, this resetting means being shown as a sheet-metal strip secured to a shaft 50, (see Figs. 2 and 9,) carriedfor oscillation in the supports 4 and 4 and having at its left-hand end a rock-arm 51, carrying an antifrietion-roll 52, adapted to travel on the periphery of a cam, such as 53, (see Fig. 10,) secured to the main shaft S, the antifriction-roll being held to its Working position as by means of a spring 54, secured to the rock-arm 51 and to the support 4.

The operation of a feed mechanism constructed in accordance With my present invention as herein set forth is as follows: It

D is continuously rotated in the direction indicated by the arroWin Fig. 2, it will be seen (see Fig. 1) that the cam 31 Will rst actuate the link 30 to advance the jacquard the interval between two adjacentpins, whereupon the tumbler-carrying frame will descend, and by the striking of the depending finger 40 of the tumbler corresponding to suchr pin upon a jacquard-pin said tumbler will be oscillated from its normal unset position to its set position. (See Fig. 1.) The operation of the cam 43 will then cause the tumbler-carrier to rise, and the set tumbler will operate theindieating member i' corresponding to said tumbier, the indicatork being oscillated a distance snfcientto shift the roll 9 into the path of movement of thatfeed cam which corresponds to the indicator engaged by the tumbler, the movement of the indicator I being transmitted to the angle-lever or feed-member shifter 48 by the rock-arm 47 of the shifteractuating indicator and from said angle-lever to the feed member, which will be shifted thereby along the carrier 5 to the desired position, the spring 10 being put under tension Immediately on the shifting of the feed member the feed-member detent CZ is carried to the position shown in Fig. 7 by the operation of the spring 16, Which carries the roll 14 doWn the cam-face of the cam 15, and the feed member is thus locked in its Working position during its feed movement. The roll 9, which up to this time has been in contact With a surface concentric With the axis of the shaft S, Will now ride off from such concentric periphery and up the cam-surface of that one of the feed-cams into the plane of which it has been shifted by the angle' lever or shifter 48, and hence the feed-segment 7 Will be actuatedas, for instance, from the position shown in v ments will cause a corresponding partial roment, and hence proportionate to the movement of the feed-screW-actuating feed member or feed-segment 7. On the descent of the tu mbler-carrier and before it reaches the limit of its descending movement the roll 52 is carried by the spring 54 to the position shown in Fig. 10, and said tumbler is restored by the resetting-blade R to its normal unset position. As soon as the roll 9 arrives at the end of the face of the cam by which it has been actuated the roll 14"'rides up the cam 15, as shown in Fig. 6, and releases the detent d from engagement with that stop on the feed member Which it engaged at the beginning of the feed movement, and the feed member is then shifted to its normal position by the force of the spring 100, as shown in Figs. 3y and 4.y At the saine time the feed-member shifter 48 is restored to its normal position by the roll 6.

and the combined action of said shifter and.

the spring 46 also causes a corresponding return movement of the indicator I to its normal position.I (Shown in full lines in Figs. 1 and 9.)

From the foregoing description it will be apparent that the operation of the indicator is absolutely dependent upon the setting of the tumblers by the pins of the jacquard, and hence if any of the jacquard-pins Were missing the tumbler-carrier would oscillate ineffectively and the indicator, the feed-member shifter, the feed member, and the parts controlled thereby would operate intermittingly. It Will be seen, therefore, that the apparatus illustrated herein comprises two separate mechanisms, one of Which may be ineffective While the other is continuously operating.

As the feed-cams constitute the means for controlling the advance of the traveler 20, it Will be evident that my invention comprises` in combination with a feed-indicator and a feed-movement controller, a feed member normally in inoperative relation with said controller and shif table by the indicator into operative relation With such controller, the feed member being automatically retrogressive or reactive to such normal position, a plurality of these feed -movement controllers being shown for the purpose of imparting variablefeed movements to said traveler, and the feed member being shiftable by the feed-indicator into operative relation with any selected controller. These feed-controllers or feed-actuators are also rotatable in unison and preferably, as before described, about a common ICO IIO

axis. As the feed member is shiftable axially to its Working position and is oscillatory about its axis, I also consider the employment of a feed member having its feed movement transverse to its shifting movement a feature of importance. Moreover, I prefer to provide a feed member automatically retrogressive toward the axis of its feed cam or feed-movement controller, as Well as to its normal or non-Working position.

As before stated, the movement of the feed member depends upon the setting of a tumbler by the jacquard, and hence when my improved feed mechanism is employed in connection with a jacquard said mechanism embodies two portions, one of which is controlled by such jacquard and constitutes an actuator for the other, While one of said portions also forms a feed-indicator, the feed-indicator being illustrated herein controlled by a feedindicator actuator.
