JACQUARD MECHANISM.

SPECIFICATION forming part of Letters Patent No. 573,622, dated December 22, 1896.

Application filed June 5, 1896. Serial No. 594,422. (No model.)

To all whom, it may concern:

Be it known that I. FRANCIS I-I. RICHARDS, a citizen of the United Stat-es, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Jacquard Mechanism, of which the following is a specification.

This invention relates to Jacquard mechanism, and especially to a Jacquard mechanism adapted for use in connection with a keyoperated apparatussuch,for instance, as a type writing machineand by means of which mechanism indications may be selectively recorded on a jacquard and the latter operated to actuate a driven apparatus controlled by the indications so recorded.

My present invention is in the nature of an improvement upon that shown, described,

and claimed in my application, Serial No.

594,651, filed June 8, 1896.

In my application above referred to the jacquard which I preferably employ is represented as an endless one having two independently and difierentially progressive runs, the jacquard being mounted on a suitable carrier in such a manner as to permit its runs to advance difierentially around the same and to move the jacquard-carrier bodily when either of the runs travels a greater distance than the other in a given time, the jacquardcarrier being movable between two extreme positions, so as to permit the recordation of indications upon one run of the jacquard, which indications are substantially utilized at the other run to operate suitable j acquardactuated means.

The main object of my present invention is to provide an improved construction and organization of the several cooperative devices which constitute the traveling jacquard apparatus, the improvements being especially designed and in tended to facilitate the assembling of the several parts and topermit the insertion of the assembled jacquard apparatus into and its removal from the framework or machine of which it forms a part.

In the drawings accompanying and forming part of this specification, Figure 1 is a side elevation of a type-writ-ing machine embodying my present improvements, the rear portion of the machine being shown in dotted lines. Fig. 2 is an enlarged plan of a portion of the same, parts of the mechanism being broken away to show the construction more clearly. Fig. 3 is a sectional side elevation of the same, looking from the left hand in Fig.2, and also having portions of the framework removed. Fig. 4c is a transverse section of the same, the section being taken in line 4 4, Fig. 3. Fig. 5 is a detail sectional side elevation illustrating the jacquard-actuating means for differentially advancing the two runs of the jacquard and shows the actuating means for the lower run in its working position for advancing said run. Fig. 6 is a similar view showing the jacquard at one end of its range of movement and the actuating means for the lower run of the jacquard as uncoupled, so as to prevent the further advance of said run. Figs. 7 and S are corresponding views showing the jacquard-actuating means for the upper run in positions corresponding, respectively, with the positions of the actuating means for the lower run shown in Figs. 5 and 6, respectively. Figs. 9 and 10 are sectional detail side elevations showing different positions of the resettingpawls (hereinafter more particularly described) for restoring the jacquard-actuated devices or tumblers to their normal unset positions after said pawls have operated to actuate the type-arms of the machine. Fig. 11 is a detail transverse section illustrating the guides for supporting and controlling the movements of the jacquard apparatus. Fig. 12 is a detail side elevation of one of said guides and the adjacent framework. Fig.

13 is a sectional plan of my improved jacmechanism embodying my present improvements. In the present case this mechanism is illustrated carried by and embodied in a type-writing machine; but only'so much of such a machine is illustrated as is deemed necessary for a clear understanding of my presdesignated in a general way by K) is illustrated, these keysbeing shown connected in a suitable manner to key-levers, such as L, of ordinaryconstruction. Said key-levers are represented pivoted near their centers and held in their normal positions by means of springs, such as 6.

The jacquard which I'employ may be any suitable traveler adapted to have indications recorded thereon at one point in its movement, and to control by means of such indicators the actuation of, corresponding operated devices-such, for instance, as the typearms shown in dotted lines in Fig. 1. This. jacquard is illustrated at J as an endless band or belt capable of bodily movement longitudinallyof the machine for the purpose of. permitting the actuation of one run thereof dif:

. ferentially relatively to the movement of the other, and as comprising apluralityof interchangeable jacquard -links, such as, j, constructed so asto be slidably detachable from the jacquard-belt transversely of said, belt. These links are also illustrated having in their outer faces and preferably at the opposite ends thereof parallel series ofidrive-openings, such as Sand 8, adapted to be engaged by the teeth of suitable, sprocket-wheels located at opposite sides of the jacquard-belt and adjacent to the respective runs thereof for the purpose of independently actuating said runs. The particular construction and organization of this jacquard-belt constitute no part of my present improvements, but form the subject-matter of a separate application filed by me June 4, 1896, Serial No. oil 248; It is obvious that any suitable endless band adapted to carry indicating-actuators, as hereinafter described, might be employed int-he present case instead of the belt or chainrepresented in the drawings.

As before stated, the drive-openings 8 and 8' are adapted to receive the teeth of suitable sprocket wheels for imparting traveling movementsto the two runs of the belt, and sprocket-wheels suitable for this purpose are illustrated at 9 and 9, carried for rotation by a shaft 10, adjacent to thewlower run of the belt, and at 9" and 9", carried by another shaft 10, close to the upper run of the jacquard, the

shafts

10 and 10, being journaled, respectively, at their opposite ends in the side frames 2 and 2".

The operation of the gears 9 and 9' isillustrated herein eifected from the keys K by means of paw-ls,,such as 12, adapted to cooperatewith and actuate a pair of ratchetwheels, such asll, carried by the shaftlO in fixed relation with the gears 9 and 9, these pawls being represented as mounted for oscillation on a universal bar, such as U. This universal bar is shown extending entirely across the machine beneath and immediately adjacent to the bank of key-levers L and carried at the rear ends of a pair of rock-arms 13, mounted on studs carried by the side frames 2 and 2, springs, such as 14, being illustrated also normally holding the forward ends of these rock-arms in their normal positions.

It should be understood that the pawls 12 will be held with their Working points normally in contact with the teeth of the ratchetwheels 11, as,f0r instance,by means of springs, such as 15, engaging extensions, such as 12', of said pawls.

It will be apparent from the foregoing that the key-levers, the universal bar U, the gears 9 and 9, and the pawls 12, carried by the universal bar, constitute jacquard-actuating means intermittentlyoperative for advancing the lower run on each depression of a key.

As has been hereinbefore stated, the enclless jacquard is bodily movable for the purpose of permitting the upper and lower runs to be operated at different speeds. In the present casethisbodily movement is rendered possible by supporting the jacquard on a j acquard-carrier mounted on the side frames 2'. and 2, this jacquard-carrier being shown guided by suitable ways and movable between two extremepositions.

Any suitable means may be employed for recordingv the desired indications upon the jacquard, as its lower run is caused to advance by the operation of the selected keys. I prefer, however, to record these indications by the setting of selected members carried by the jacquard and movable relatively thereto and adapted to actuate the devices which are controlled by the indications of the jacquard. These settable members I term indicating-actuators, as they not only indicate that the operation of a determined device or mechanism may take place, but form the means for operating such actuated part or parts. It will be obvious that the jacquard will have a plurality of such indicating-actuators, and these are illustrated at p disposed in transversely-separated longitudinal series extending completely around the jacquard, there being one series for each character, and therefore one for each key-lever. As the lower run of the jacquard is advanced the same interval at each depression of a key, these actuators are also represented as spaced equidistantly longitudinally of the jacquard, said actuators being also arranged, preferably, in transverse series perpendicular to the longitudinal series.

One form of indicating-actuator adapted to record indications on the jacquard and subsequently operate jacquard-actuated means is represented as a jacquard-pin (see Fig. 4) seated in a suitable aperture in the jacquard and oscillatory from such aperture as a center, this pin being. preferably formed with a forked shank portion 19, seated in a socket in the corresponding link of the belt, and an offset or crank portion having a head 19 parallel with the shank.

For the purpose of setting a determined number of indicating-actuators each key-lever L is illustrated having a setting-actuator, such as 20, disposed transversely of thekeylever and preferably constructed so as to have a convex working face or cam-face, such as 20. (See Fig. at.) These faces 20'are adapted to engage the heads 19 of the indicating-actuators or jacquard-pins to shift or oscillate the same from their normal unset positions to the oblique set positions, in which the indicating-actuators will be operative for moving the jacquard-actuated means.

The upper run of the jacquard is intended to be operated entirely independently and differentially relatively to the movement of the lower run. For the purpose of so actuating such upper run a continuous rotative bandwheel is shown at D, carrying an eccentricrod 21, operating an angle-lever 22, fixed to the rock-shaft 23, j ournaled in the side frames 2 and 2, the upper end of the angle-lever having pivoted thereto actuating means in the form of a long push-pawl, such as 25, normally held with its point in engagement with the teeth of a ratchet-wheel, such as 11, fixed on the shaft 10", the pawl being kept in place by means of a spring, such as 26. It will be seen that on each rotation of the band-wheel D the pawl 25 normally will operate to advance the upper run of the jacquard in the direction indicated by the arrow in Fig. 3, and the throw of this pawl and the lengths of the teeth of the ratchet-wheel 11' are such that said run will be actuated at each rotation of said wheel the same interval that the lower run is advanced on the depression of a key, but with a regular step-by-step movement.

In the present application I have shown the continuously operative jacquard actuating means for the upper run as combined with j acquard-actuated means to form a combined jacquard-actuating and jacquard-actuated apparatus. This jacquard-actuated means, which will also be referred to as the primary jacquard-actuated means, is represented embodying a tumbler-carrierbar, such as 29, fixed on the rock-shaft 23 and kerfed at its forward end to form a series of alined tumbler-separatin g members, such as 30, (see Fig. 2,) having registering apertures therein adapted to receive a tumbler-carrier or rod, such as 31, on which the actuated devices are mounted. These devices are shown at t as oscillatory tumblers, one for each longitudinal series of indicating-actuators, each tunibler being normally in an unset position, but settable by the indicating-actuators of its se ries into position for operating secondary actuated devices. It should be understood that the tumblers will be held in frictional en gagement with the adjacent faces of the tumblerseparating members, so that when any tumbler is in one position it will have no tendency to move until it is positively actuated.

For the purpose of limiting the movements of the tumblers stops are provided for stopping the same in their set and unset positions alternately, these tumbler-stops being. represented herein at 32 and 32, (see Figs. 5 and 6,) forming the rear walls of the kerfs in the tumbler-carrier bar.

The tumblers t are preferably interchangeable and each is illustrated havinga face 33 (see Figs. 5 and 6) inclined toward the jacquard and adapted to be engaged by its respective indicating-actuator and carried away from the jacquard, the oscillation of the tumbler to its set position being effected by this movement. Each face 33 is also shown (see Fig. 4) having a channel therein in the path of its set actuator, to thereby guide such actuator between the walls of said channel during the travel of the actuator along and over the face 33. trated having an arm 34: rising therefrom for operating the secondary actuated devices, the movement of such secondary device being accomplished, preferably, after the tumbler is set and not by the setting movement of such tumbler. In the present case the oscillation of the tumbler-carrier bar is utilized to actuate the secondary device after the tumbler has been set by its proper indicatingactuator.

The secondary actuating means may be of any suitable construction. I have shown the same in the present application as comprising a plurality or bank of type-arm=operating levers, such as L, corresponding in number with the respective tumblers and also with the longitudinal series of indicating-actuators of the jacquard, as well as with the keylevers L. Each of these levers L is represented having a depending finger 35 in position to be engaged by the arm 34 of its tumbler when the tumbler is in its set position, this finger being preferably notched at its extremity, as illustrated at 35, to insure the engagement of the arm 34 with such finger during the operation of the type-arm-operating lever by the tumbler.

The devices which may be controlled by the levers L constitute no part of my invention, and are not illustrated in detail herein, as it is obvious that my improved Jacquard mechanism might be applied to many kinds of apparatussuch as, for instance, the heddlelevers of looms or the levers of matrix or analogous machinesother than that shown in the drawings of this case. 7

After the operation of the tumblers by the jacquard-pins it is necessary to restore such pins to their normal positions, in order that new combinations may be set up on the jac-- quard by the operation of the several keys. Hence I have shown at R (see Fig. 4) resetting means in the form of a fixed bar or comb disposed transversely of the jacquard and se- Each tumbler is also illuscured to the side frames 2 and 2 and embodyingaplurality of resetting members, one for each longitudinal seriesof jacquard-pins, these resetting members being alined, respectively, with such respective series of pins and having their resetting-faces formed as obliquely-disposed cam-surfaces in line with the set pins and shaped so as to turn said pins from their oblique to their unset positions.

I have also represented (see particularly Figs. 9 and 10) resetting means for restoring the tumblers to their normal positions after they have operated the levers L. This resetting means is represented at R as a sheet metal strip secured to a rock-shaft 37, journaled inthe side frames 2 and 2, said rockshaft being shown having fixed thereon at its right-hand end a rock-arm 40, hinged by means of avconnecting-rod 4:1 to a link 42, carried'by the side frame-2f and having at its outer end an antifriction-roll 43, adapted to travel onthe cam-surface 44 of a cam 44, secured to the right-hand end of the drivingshaft S, on the opposite end of which the bandwheel D is fixed. A coiled spring is representedat 45 for normally holdingthe antifriction-roll 43 in contact with the cam-surface 4.4.

One of the main features of my present improvements relates to the construction and organization of the traveling jacquard apparatus and its cooperative devices, and these will now be described. The j acquard-carrier which I prefer to employ and the guides and supports therefor are fully illustrated in detail in Figs. 11 to 17, inclusive. In Fig. 13 thiscarrier is shown as a rectangular frame embodying a plurality of parallel longitudinal truss-bars, such as 16, connected by means of tie-rods, such as 17. lhe truss-bars represented in this figure are interchangeable, and each isillustrated having a sheet-metal body portion bent at its edges to form a pair of parallel members, one of which presents a wide surface for supporting the jacquard-belt during the travel of the upper run over the carrier. Each of these truss-bars is shown having fixed thereto at one end thereof an outwardly-facin g forked bearing, such as 16, preferably riveted to the end of the truss-bar, as shown in Figs. 16 and 17. At itsother end each trussrbar is illustrated having two inturned shoulders disposed in parallelism with each other and having registering openings, these shoulders being formed from the sheet metal of the bar, the outer one by simply bending the extension 16 at right anglesto the main member, while the other is represented at 16' formed by a substantially semicircular portion of the main body of the trussbar by stamping such portion and bending the same into parallelism with the shoulder 16". The openings in these shoulders are adapted to receive a shank 160 of an outwardly-facing forked bearing, such as 160, which isrepresented as adjustable by means of such shank longitudinally of its respective trussbar. One end of this shank is also shown screw-threaded and having thereon an adjusting-nut 161 and a check-nut 162 for controlling the position of the adjustable bearing relatively to the fixed bearing in the opposite end of the truss-bar.

As before stated, the truss-bars are connected by meansof tie-rods 17, and for the purpose of properly spacing the truss-bars relatively to one another these tie-rods are shown having mounted thereon truss-barseparating sleeves, such as 17, between the truss-bars, said sleeves bracing and supporting the same. The ends of the tie-rodsare threaded and are provided with nuts and washers in the usual manner for holding the several parts assembled.

Theadj ustable bearings are illustrated disposed in parallelism with the fixed bearings 16, and shafts 18 are shown supported for rotation the one in the fixed bearings and the other inthe adjustable bearings of the jacquard carrier. secured thereto a plurality of carrier-wheels or jacquard-supporting wheels, such as 18', these being represented in Fig. 13 as interchangeable- From the foregoing description of the jacquard-carrier it will be apparent that this is longitudinally extensible and connects a pair of rotary carriers mounted in and removable longitudinally from outwardly-facing forked hearings in the opposite ends of such jacquard-carrier. Moreover, such an extensible carrier as-that just described forms a jacquard-extending jacquard-carrier which may be adjusted so as to hold the jacquard-belt taut at all times and which will permit the taking up of any slack that may result-from long use of the jacquard-chain.

The jacquard apparatus is movable, as before stated, between two extremepositions, and comprises the jacquard-carrier just described and an endless jacquard inclosing and held extended by said carrier. ratusis designed to be inserted into the machine and removed therefrom in an assembled condition,said apparatus being sustained by suitable supports and directed in its movements by proper guides, such as top guides, parallel with the supports and parallel side guides against which the ends of the links of the jacquard-belt abut. In the present case the endless jacquard itself is shown sustained by the jacquard-supports and entirely inclos-' ing the jacquard-carrier and the parts fixed thereon.

At 0' and 0- I have-represented a pair of channeled bars disposed in parallelism with each other, and each having a side guide contiguous to the sides of the links, and a pair of

parallel members

170 and 170, constituting, respectively, a top guide and a jacquardsupport, the construction being such that saidbars constitute jacquard-supporting side guides and positively position the traveling jacquard apparatus in vertical and lateral Each shaft preferably has This appa-.

IIC

directions, the top guides serving also to prevent the rising of the links of the upper run of the jacquard and consequent inisalinement of the same.

The operation of the mechanism described herein as embodying my present improvements is as follows: On the depression of any key by the operator the corresponding keylever is actuated and the universal bar U is forced up, carrying with it the pawls 12, and thereby rotating the ratchet-wheels 11 and the sprocket-wheels 9 and 9, whereby the lower run of the jacquard is caused to advance a space, as shown in Fig. 5. At substantially the same time the cam-face 20 of the correspondin g setting-actuator 20 engages the head 19 of that indicating-actuator of its respective series which has just been brought into working position by the advance of the lower run, and such indicating-actuator is shifted from its normal position to a position out of line with or oblique to the remaining actuators of its series. A determined succession of indicating-actuators may be set thus by the selective operation of the keys without causing the actuation of any of the operated devices adjacent to the upper run, and the setting up of the indications on the lower run may be continued until the jacquard and its carrier reach the limit of their movements toward the front of the machine. At the same time that these indications are being recorded the band-wheel D will be normally continuously rotating and regularly carrying the parts controlled thereby in their respective paths of movement, the upper run being carried in the direction indicated by the arrow in Fig. 3 step by step on the rotation of the ratchet wheel 11 by the pawl 25 and the consequent rotation of the sprocket-wheels 9" and 9. As soon as those indicating-actuators which have been set at the lower run are brought into operative relation with the tumblers at the upper run by the continued advance of the two runs of the jacquard such tumblers will be selectively carried into engagement with the fingers of their respective levers L and will actuate such levers, (see Figs. 5 and 6,) each of said tumblers being restored to its normal unset position on its return from engagement with its actuated lever by the engagement of the resetting-bar R with such tumbler, as shown in Fig. 9, the resetting action being fully accomplished before the tumblerhas reached the limit of its downward movement. (See Fig. 10.) The cam-surface 44 is so shaped that, as shown in Fig. 9, as the antifriction-roller 43 leaves the top of the cam the set tumblers will be forced back quickly to their unset positions by the action of the spring 45.

The action of the jacquard will be readily understood by reference to Figs. 1, 3, and 5 to S, inclusive. The jacquard frame or carrier is capable of bodily sliding movement in the guideways r of the main frame, and if, for instance, the lower run or bottom of the belt is blocked or prevented from rotative movement by the engagement of the teeth 9 and 9 with the sockets 8 and 8 it is obvious that the upper run or top portion of the jacquard may be independently and bodily actuated by the mechanism described as long as the blocking action continues until either a part or substantially all of the portion of the jacquard between the blocked part thereof and the axis of the drum 18 on the right is taken up. In this operation, as is obvious, the frame carrying the endless jacquard slides in the guideways 0* and the belt slips around the rollers or drums 18, by virtue of which action the result just set forth may be accomplished.

As it is obvious that neither of the runs of the jacquard can be operated uninterruptedly when the two runs are differentially actuated, and especially when, as is the casein the construction described herein, one of the runs is operated continuously at a relatively rapid rate of speed, while the other is advanced intermittently at a relatively slow speed, some means must be employed for preventing the advancing movement of each run when such movement has brought the jacquard and its carrier to the limit of their travel in one direction. a For the purpose of preventing this advancing movement after the jacquard has arrived at either extreme position I have shown herein means for throwing the driving-pawls out of engagement. with the teeth of their respective ratchet -wheels at such times. The outer truss-bars are illustrated (see Fig. 13) having projecting from their outersides adjacent to the'ends thereof stops, such as 46 and 47. The stops 46 are so disposed that when the jacquard reaches the position shown in Fig. 5 the depression of a keyif the upper run is not simultaneously advancedwill cause said stops to be moved by the jacquard into engagement with the upper ends of the levers 120, which are illustrated carrying at their lower ends pins 120, adapted to engage extensions, such as 12, of the pawls 12 to carry the operating-points of the pawls out of the path of the teeth of the respective ratchet-wheels 11. Stops are represented at 121 located in such positions that they will lie above corresponding stops, such as 12", of the pawls 12 when the pawls are thrown out of engagement with the teeth of their ratchet-wheels; and the advance of the lower run will be prevented by these stops until the upper run has been advanced a distance sufficient to cause the stops 46 to be carried backward out of the path of the levers 120. The stops 121 are represented as of the bypass type for the purpose of permitting the pawls to pass the same in moving from the position shown in Fig. 5 to that shown in the jacquard and its carrier reach the position shown in Fig. 7, the jacquard apparatus is at the end of its movement toward the rear of the machine, and the stop 47 has been carried into engagement with the depending arm of an angle-lever, such as 470, which is shown pivoted to the side frame 2 and having at the outer end of its upper arm a camface, such as 470. Thiscam-face is carried on such oscillation of the angle-lever into engagement with a pin, such as 25, which is represented fixed on the pawl 25, and on the return of the pawl from the position shown in Fig. 7 causes the pin 25 to ride up the cam-face 4'70 and thus prevents the point of the pawl from dropping into the next tooth of the ratchet-wheel 11, (see Fig. 8,) so that on the next forward movement of said pawl it will be ineffective to rotate such ratchetwheel. It will be obv-ious'that until the jacquard and its carrier have been actuated again toward the front of the machine by the action of the key-operated devices controlling the lower run the driver D, while continuously rotating, will not impart advancing movements-to the upper run and will be ineffective until the angle lever 470 returns to its normal position, in which it is held by means of a stop=arm engaging the rear wall of a slot in the side frame 2, the other end of the slotbein g illustrated controlling in the same'way the' normahposition of the lever 120. (See Figs; 1 and 4.) Two of these slots, which are designated by 125, are represented one in each of the side frames 2 and 2.

As it is verynecessary to prevent lateral movement of the setting-actuators and of ad jaoent' portions of the key-levers during the'settin g of the jacquarcbpins, I have shown in the drawings means for guiding these parts in their movements toward and from the jacquard. The setting-actuators are disposed substantiallyperpendicular to the ends of the levers in the present case, and hence by providing guides for these actuators and for the portions of the key-levers contiguous thereto each actuator may be held against.

both lateral and rotative movement in ad vancing toward the indicating-actuator which it is designed to set. I have represented at 126 a guide-bar disposed transversely of the machine and having two series'of guide openings or slots therein, such as 126 and 126", corresponding slots of each-series being shown lying in the same plane, so that the walls thereof will form guides for positively locatin g the setting-actuators when these actuators are operated.
