To all whom it may concern:

Be itknown that I, SAMUEL F. PATTERSON, a citizen of the United States, residing at the city of Baltimore, in the State of Maryland,

have invented certain new and useful I|n provements in Power-Looms, of which the following is a specification.

This invention pertains to powerand it consists, primarily, in combining with the usual weaving-apparatus or loom proper jacquard mechanism and automatic devices for renewing the filling in the shuttle whenever it becomes exhausted or when the filling thread or yarnbreaks.

The invention further consists in certain novel features, "details, and combinations hereinafter set forth, whereby the invention thus generally stated is efl'rciently embodied and carried into practice.

In the accompanying drawings, Figure l is a perspective view of a loom embodying my invention; Fig. 2, a top plan view of a portion thereof, showing more. partihularly the mechanism fol-supplying filling tothe shuttle Fig. 3, a vertical section on the line a; w of Fig. 2; .Figs. 4 and5, detail views of the detector mech'anismwhich serves to ascertain tain other parts shall go into operation; Fig.

6, a diagrammatic top plan view of the driving and controlling mechanism-of ,thelooni intended to' show the general and relative a detail view of the feeler and latch mechanism.

Prior to my inventionjacquard mechanism of difierent types or styles had long been employed in connection with looms to produce figure or pattern efiects. So, too, but for a shorter time, automatic mechanism for introducing into the shuttle a fresh or filled bobbin, spindle, or cop when necessary had been combined with weaving mechanisms orloon s proper adapted to produce plain fabrics only. Each of these attachments or appliances had its useful purpose and function and each added greatly to the efiiciencyor capabilities of the'loom in one or another way. I have combined these several mechanisms in one structure, whereby the production of figured fabrics is greatly increased over the produc looms;

in proper position tov tion of loomshavi-ng jacquard mechanism used prior to my invention for making th same fabrics, and the cost of such prod action is thereby also decreased.

Fig. 1, A indicates the loom as a'whole, 13 the jacquard mechanism, and Q'the automatic bobbin, spindle, or cop feeding mechanism, which constitute the. main elements or groups of elements embraced in the novel combine tion constituting my invention.- In themselves theseveral mechanisms just indicated may be of any usual or approved construction, though I have selected and have represented in the drawings those types o each which I deem best suited to the purpose. in .view. 3

Referring now not only to Fig. 1, but to the other figures in which parts mentioned may be found, the loom A will be seen to comprise D, the'cranks of which connect by pitmen or connecting-arm's E with the swords or carry-- ing-arms F of the lay G, a picker-shaft H, with the usual cams, picker-sticks and intermediate pickingsha'ft, a shuttle I, and the customary harness, beams, itch, employed in a power-loom having jacquard mechanism.

The Draper loom, being one well and fav orably known, is here taken as an illus ra iv type, the customary harness or heddle frames and mechanism for operating thesame, however,being done awaywith and the customary harness of a power-loom having jacquard mechanism beingintroduced in place thereof.

The throw and the timing of the .cranksa, b, and care carefully proportioned and arranged withreference to the relations existing between the loom proper and the jacquard mechanism. The two shafts D and II are geared'together and maintain the predetermined relation and times o'faction.

Figs. 2 and 3 illustrate the magazine or battery for holding a series of bobbins, spindies, or cops duly wound-with the filling a clear understanding of the combination of .the several groups of mechanisms above named. The magazine or battery comprises first a vertical plate or diskN, rising from a bracket 0, bolted or otherwise made fast upon the, breast-beam P and formed with an overhanging horizontal flange g, which extends nearly around the circumference of the disk, terminating, at a point belowand nearly in vertical line with the center of said disk and at a short distance from a stop or abutment it, formed upon the supporting-bracket or the plate itself. From the center of plate or disk N projects a horizontal stem or spindle 2', which constitutes an axle for a drum or carrier Q -,coinpi-ising a peripherallynotched diskf orrecessed disk or head 7c, connected and spaced by atubular sleeve Z, which fits and turns upon the spindle t. The notches in of the disk or headj'are ot" a size and form to receive and hold the heads of the bobbins or spindles R, whose tips'arecarried in the radial grooves n of disk k. The heads are retained in position by the overhanging flange g and the tips are retained in, the radial grooves n by curved spring-tongues 0, se-.

a cured in thegrooves and projectingoutwardly somewhat beyond the periphery of the dislek,

-so that they maybe readily pressedback to {permit insertion of a full bobbin or spindle. Projecting beyond disk 70 and concentric therewith is a supporting-plate p for the weft or filling th reads ot the several bobbins, spindles, or filling-carriersof the magazine or battery. The periphery of this supporting-plate is fashioned, essentially, like a ratchetwheel,

or spool 11, about which the ends of the filling-threads are wound after passing from the filling-carriers over thesupporting-plate 1). By being thus wound gnpon the boss or spool each'thread or yarnis caused to draw from its spindle or carrier asthe latter, inserted "head 7'. and a'radially ,grooved' into the shuttle, is carried through the shutone at a time removed from the magazine or batteryand delivered into the shuttle. This operation is effected at that instant when the shuttle is in its box at that end of the loom at which the magazine is located and when said box and its contained shuttle are immediately beneath the opening left between the flange g and abutment. h, as indicated in Fig. 3. There is at this instant the brief dwellor momentary rest of the lay incident to the cranks passing the center and reversing the motion of the lay, and this is of course the most available time atwhich to remove one bobbin or spindle and insert another; The ejector S is pivotally supported upon the bracket or upright plate N, its inner end being held up by a springr and occupying a position im mediately over the lowermost spindie or bobbin R of'the'battery or magazine, I

as seen in Fig. 3. Carried by the lower arm of the ejector, which as a whole is in the form of an elbow-lever, is a swinging memher 3, upon which is adjustably mounted a notched block t. A spring i, Fig. 6, coiled about the pivot by which the member s is attached to the ejector-arm, tends to swing the member. s inward, and thereby to elevate the notched inner end of block t. -This tendency is counteracted and normally overcome by a hook or linger u, adjustably secured to a depending arm of a T-shaped lever T, pivoted upon a stud or axle a, projecting from the plate or upright N, said finger or hook u engaging astud v on the block if or its carrier, as shown in Fig. 3. "Hook or fingernoccupies under different conditions the positions shown by full and dotted lines in Fig. 4 and by full lines in Fig. 5,its normalposition being that shown by fulllinesin Figs. 3 and 4, so that the block t normally stands in the position shown in said Fig. 3. Hook or finger a is retained normally in said position through the stress ofaspring '10, acting through a lever .12 and link g, which latter is slotted at itsupper end and hung upon a stud z, projecting from an arm of level T on the opposite side 'of the pivot-axis of said lever from that of the arm which carries hook orfinger it. tically from lever T and is connected by a links with a detector-lever U, which normally occupies the position indicated by This detector arm or lever is pivotally supported upon an arm or bracket of the magazine or battery frame and full lines in Fig. a.

is carried to an d-. held in'the positionindicat ed in Fig. 4 bya spring (1, coiled about the stud on which it is-pivoted, fixed at one end to said stud and hearing at the other end'against the lever U. Spring (1' exerts force sufiicient .A third arm I) rises ver roe v parts in the positions shown by full lines in Fig. 4. Lever w is secured upon a rock-shaft 6', carried in hangers or bearings attached to the breast-beam P or to other convenient supports. The rock shaft 9' extends across the frontof the machine and carriesatthe end opposite that at which lever a: is located an upright arm f. (Seen in Figs. 1 3, at, 5, 6, and 7.) Theupper end of-arm f is bent laterally and then inward, terminating just above the top face ofthe breast-beam and in position to be engaged by the filliug-feeler slide V (on the breast-beam) when said'slidc is moved outward, as happens when the filling thread or yarn breaks or gives out. This slide is shown in Figs. 6 and 7 and.carries at its inner end the pivoted filling-fork 2.0, which as the lay swings outward encounters or is encountered by the filling-thread, if the same be present. The weft-fork is of the form shown in Fig. 7, comprising a horizon.- tal member and a substantially vertical member, which latter lies, in the path of the thread or filling as the lay swings outward. The horizontal or outer member of the fork is here shown in the form of-a bail to engage a hook 71 pin-jointed to the lever or hammer it, carried and oscillated by the lever i, in turn actuated by'cam j on the shaft II. So long as the filling is uninterrupted through depletion or breakage it will on the outward throw of the lay encounter the weft-fork TV and lift its horizontal member so as to prevent engagement with the hook 77. and con-' sequently prevent backward movement of the slide-in or upon which the'fork is pivoted. If, however, the thread or filling fail from any cause, the fork W will not be acted upon,

and its horizontal portion being unlifted its bail will lie in the path of the hook it and will in consequence engage said hook and cause the fork and the slide V, inv which it is mounted, to be moved backward. In thus movin'gbackward'the slide encounters the arm f of rockshaft e, turning said shaft and lifting arm or lever :20 and link y, overcoming in so doing the resistance or stress of-spring w. Owing to the slotting of the link y the lifting thereof does not in itself afiect the three-arm lever T;but it leaves" .saidlever free to be moved through its con-- nection with the deflector U, actuatedby spring d'.- It the shuttle is properly posi tioned within the' shuttlebox beneath the magazine at the time the hammer h swings ontwardand after failure of the weft thread or yarn, the'elevation of link y in the manner just described will be followed by the swing ing of detector U to the position indicated by dotted linesin Fig. 4; but should the shuttle not be properly positioned within the box it would be encountered by the detector U, as in Fig. 5, and thus the parts would be precluded from reaching the position indicated by dotted lines in Fig. 4. Assuming that the shuttle has reached its proper position in the shuttle-box and that the weft-thread has failed, thereby bringing about a. movement of the parts to the position indicated by dotted lines in Fig.4, hook or finger u will thereby have relieved stud t of pressure and will have permitted the spring t to turn or swing the'carriers and block if to a position where the notch 1" in the end of said block will be in the path of a projection is on an arm carried by the lay G. iVhen theblock is brought to the position indicated the born or projection 7c encountering the block 2, will cause,

the ejector 'S to swing about its pivot or axle, and thereby to press its head or ejecting portion against the spindle or bobbin of the mags zine, which at that moment lies againstthe.

abutment or stop it. The movement of the ejector is such as to carry the bobbin or spindle out of the notch m of the disk or head j and out of the groove 71 of disk and to force said bobbin downward into contactwith the bobbin in the shuttle I.

through it of the ejected bobbin or spindle,"

as indicated in Fig. 3.

The usual devices for stopping the loom when a warp-thread breaks or when the shuttle does not reach its proper position at the end of the shuttle-box and a belt-shifter, brake, and like parts will or may be provided; but as these are of well-known construction it is not deemed necessary to enter into a further or more detailed description of them.

The same is true ofother details, such as the tip-support for the bobbin or spindle in position to be delivered from the magazine or carrier, the mechanism for rotating said carrier and arresting it at the proper point, &c. As to all these matters any suitable construction and arrangement known in the art "may be employed-such, for instance, as used in the Northrop magazine or battery looms now extensively in use and illustrated in United StatesLetters Patent to J. H. Northrop, dated June 23, 189 1, and numbered 454,810. The

magazine may be the rotary type shown or.

of the hopper style.

As is usual, the overhanging flange g is here As is usual with this magazine or battery feeder,- the shuttle- KOO Iio

with the cloth-beam and the let-ofi mechanism used with the warp-beam are not shown in the drawings, and some other details not necessary to an understanding of the in vention claimedare likewise omitted to avoid confusion. Y

In the foregoing description I have set forth, and I have illustrated in the drawings, one form of mechanism for replenishing thesupply of weft thread or yarn, this involving the displacement ofan empty. bobbin, spindle, or'cop from, and the introduction of a filledone into, the shuttle, and such apparatus I deem the most desirable to use in practice. My invention, however, includes the automatic replenishing or renewal of the weft thread supply by any known form of mechanism .whencom bined with the other featur es herein set forth. Thus, for instance, it comprehends automatic devices for ejecting a shuttle the weft-thread of which has become broken or exhausted and replacing the same by a shuttle containing a filled cop, bobbin, or spindle, or supplied with weft. thread or yarn. The term weft-carrieris, therefore, used in a somewhat comprehensive sense in some of the claims and includes shuttles supplied with weft-thread, as well as bobbins,

cops, or spindles, apart from the shuttles and similarly supplied.

Having thus described my invention, what I claim isi v 1. In combination with the'weaving mechanism proper of a loom, an automatic mechanism for supplying weft or filling to the shuttle; jacquard mechanism for controlling the harness of the loom; and intermediate conuections between'such mechanisms, substan-' tially as described.

' 2. In combination'with the weaving mech-' anism proper of a power-loom, jacquard mech anism for controlling and actuating the harness thereof .a magazine 'or' battery for con- 'tai'ning a supply of filled bobbins or spindles; 'mechanism for automatically ejecting anv a, b and c; jacquard mechanism connected.

with and actuated by said cranks; and automatic mechanism for supplying filled bobbins or spindles to the loom-shuttle, substantially as described.

4. In combination with the weaving mechanism proper of a loom, automatic mechanism for supplying weft or filling to the loom when the'weft-th'read'is interrupted or exhausted jacquard mechanism for controlli ng the harness of the loom; and intermediate connections between such mechanisms, substantiallyas described.

In combination with the weaving mechanism proper of a power-loom, jacquard mechanism for controlling and actuating the barnessthereof; a magazine or battery for containing a supply of weft-carrier's; mechanism for automatically ejecting an em'pty' carrier and delivering a filled one; and connections,

substantially such as .shown and described, between said mechanisms.

6. In combination with the weaving mechanism proper of a power-loom having cranks -a, b and c, jacquard'mechanism' connected with and actuated by said'cranks; and automatic'mechanism' for ejecting empty weftcarriers and supply'in'gfilled ones, substantially as described. f v t In testimony whereof Ihave signed my name to this specification in the presence of
