SPECIFICATION forming part of Letters Patent No. 793,337, dated June 27,-1905.

Applicati n filed October 19,1904. Serial No. 229,092.

To zr/mnt it may concern.-

I e it known that I, I-Ionaon \VYMAN, a citizen of the United States, residing at \Vorcester, in the county of \Vorccster and State of Massachusetts, have invented certain new and useful Improvements in Automatic \Veft-Iteplenishing Looms, of which the following is a specification.

My invention relates to looms, and particularly to automatic weft-replenishing looms of theelass shown and described in United States Letters Patent No. 600.053, of arch 1, 1898, in which a magazine or reservoir is provided containing a series of bobbins or filling-carriers which are automatically supplied to the shuttles upon the breaking or exhaust of fill- Ihe object of my invention is to improve upon the cmistruction of the automatic weft replenishing mechanism ordinarily used in the class of looms referred to.

In my improved filling-carrier magazine. which carries a series of bobbins around its circumference and is adapted to turn or oscillate back and forth about its axis, I provide means for the adjustment of the springs which hold the bobbins seated in their sockets in the supporting-ring of the magazine. so that after the springs have been adjusted to any definite length of bobbin the bobbins will be firmly retained in their seats and correctly alined one with another for the transference of the bobbin into the shuttle. In my improvementsI also provide an improved mechanism for turning the magazine about its axis, whereby its operation is rendered more certain and accurate.

Hy magazine comprises a long sleeve carried on a central stud or pin, said stud supported at its inner end by a stand attached to the looin-frame. On said sleeve adjacent to the supporting-stand and located within the a magazine is a gear driven by an angularlyplaced bevel-pinion carried on a driven shaft parallel to the loom side. On the outer end of said sleeve is carried a disk or plate provided at its outer edge or circumference with a series of bars pro ecting inward.

To the l ends of said bars is attached a bobbin-headsupporting ring provided with a series of sockets around its circumference to receive and support the heads of the series of bobbins carried by the magazine and leaving a free space inside of the ring between it and the bevel-gear on the sleeve of the magazine for the transferrer to enter within the magazine. Outside of said disk or plate and adjacent thereto is preferably a second disk or plate mounted on the hub of the first-mentioned disk and adapted to be adjusted longitudinally thereon. The circumference of said second disk or plate is provided with a series of channels or recesses to support the tips of the bobbins. These channels coincide with the position of the sockets of the ring which supports the heads of the bobbins. 'Ihc firstmentioned disk or plate may have a series of channels to support the tips of the bobbins. On the outside of said second disk is preferably carried a series of flat springs. one for each of the channels, which springs press against the ends of the bobbins. By reason of the provision for longitudinal movement of said second disk carrying the springs the pressure of said springs against the tips of the bobbins may be adjusted as desired to hold the heads of the bobbins firmly in their sockets on the ring. I prefer to make the whole disk carrying the springs adjustable; but the individual springs may be adjustable.

Hy improved construction of the magazine permits of the transferrer being pivoted out-- side of the bobbins and extending into the magazine on the inner side of the bobbins between the gear on the sleeve of the magazine and the bobbin-hcad-supporting ring to permit the end of the transferrcr when required pushing a bobbin outward and downward into a receiving-shuttle. It also permits of the magazine being rotated in either direction.

In my improvements the actuating-shaft which carries the bevel-gear which operates the bevel-gear to rotate the magazine is located at right angles to the axis of rotation of the magazine and between the inner end of the magazine and the loom-arch, so that I am enabled to extend said shaft at its rear end to a convenient position at the rear of the loom and to mount thereon a compound motion through which the magazine is rotated in a forward direction after the bobbin has been transferred from it to a receiving-shuttle, and also carried either forward or backward, operated from the shifting shuttle-box motion as the shuttle-boxes are moved up or down to position the bobbins, having fillings of different colors to be interwoven in the fabric according as the shifting shuttle-boxes are moved.

In my improvements a spur-gear on one member of the compound motion is actuated by a rack through connections to the shifting shuttle-box motion of the class shown and described in United States Letters Patent No. 764,326, dated July 5, 1904:, to rotate the magazine backward or forward as the shuttle-boxes are raised and lowered. A pawl, actuated from a moving part of the loom when a bobbin has been transferred, acts to move the magazine from one division to another division which carries a similar colored bobbin to the one transferred.

In my improvements the supporting-stand for the stud carrying the magazine has a hub for said stud and also has a plate or disk thereon covering the end of the bobbin-headsupporting ring, and also a flange projecting over the outside of the bobbin-heads carried in the sockets of said ring, which flange serves to retain the bobbins from falling. Said stand also carries a hub for the transferrer-lever, and there is an opening through the stand for the transferrer to pass. Saidstand also has another opening for the bevel-gear on the driving-shaft, through which opening it engages the bevel-gear on the sleeve of the magazine. The plate or disk on said stand also carries a bearing for the driving-shaft near the pinion carried on it, whereby the pinion on the driving-shaft and the bevel-gear on the sleeve of the magazine are firmly held with their teeth in mesh with each other.

1 have only shown in the drawings a dc tached portion of a loom of the class referred to with my improvements combined therewith suflicient to enable those skilled in the art to which the same belong to make and use the same.

Referring to the drawings, Figure 1 is a sectional elevation of a loom-frame and inner end view of the filling-carrier magazine and operating mechanism embodying my improvements looking in the direction of arrow 0, Fig. 2. Fig. 2 is a plan view of the fillingcarrier magazineand operating mechanism shown in Fig. 1 looking in the direction of arrow 6, same figure. Fig. 3 is a central Vertical section through the filling-carrier magazine shown in Fig. 2 on line 3 3, same figure, looking in the direction of arrow 0. Fig. 4 is a detached sectional view showing a modified construction of the springs for the bobbins. Fig. 5 is an outer end view of the opposite end of the loom, showing the connections to the shifting shuttle-box rod; and Fig 6 is a detached rear view of the connections looking in the direction of arrow d, Fig. 5.

In the accompanying drawings, 1 represents the loom sides or frames; 2, the breast-beam; 3. the lay; 4:, the lay-sword; 5, the connector from the lay to the crank-shaft 6.

I will now describe my improvements.

7 is a stationary stand, preferably of circular shape, with a foot 7 which is attached by bolts or otherwise on the upper side of the breast-beam, atone end thereof. The stand 7 forms a rigid support for the several parts of the rotary filling-carrier magazine.

A bracket or angle-iron 8 is attached at one end to the loom-arch 9 and at its other end to the upper part of the stand 7 to hold said stand in position. On the stand 7 is formed a hub or boss 7", in which is secured by anut 10 the reduced end 11 of a stud 11. On the stud 11 is loosely'mounted the sleeve 12, which is held on the stud 11 to prevent any longitudinal movement-in this instance by a washer 18 and nut 14 on the outer threaded end of the stud 11. (See Fig. 3.)

Mounted on the outer reduced end of the sleeve 12 is the hub 15 of a circular disk or plate 15. The hub 15 is secured on the sleeve 12 in this instance by a set-screw 16. The circular disk or plate 15 has a series of inwardly-extending arms or bars 15 at its outer edgein this instance seven in number, which divide it into seven divisions or parts. Upon the inner ends of the arms 15 is attached a ring 17, having therein a series of sockets 17 (see Fig. 3) to receive and support the heads of the bobbins 18. The ring 17 extends within an outwardly-projecting flange 7', which extends around the stand 7, except at the lower part thereof. (See Figs. 2 and 3.) A second circular disk or plate 19 preferably extends upon the outside of the plate 15 and has a hub 19 thereon mounted on the hub 15 of the plate 15 and adjustable longitudinally thereon by means of a set-screw 20. (See Fig. The plate or disk 19 is provided on its periphery with a series of notches or sockets '19 to receive the ends or tips of the bobbins 18. Secured to the disk 19 is a series of flat or leaf springs 21, the number of said springs corresponding to the number of sockets 19 in said disk. The free end of each spring is adapted to extend into the outer end of each socket to engage the end or tip of the bobbin, as shown in Fig. 8, to hold the bobbin seated in its socket. The tension of the springs 21 on the tips of the bobbins 18 may be adjusted as desired by moving the hub 19' of the disk 19 toward or away from the disk 15 and securing it in its adjusted position by a set-screw 20, thus regulating the distance between the disk and the disk 19, carrying the springs ln Fig. 1 is shown a modified construction of the springs 21. In the construction shown in said l'igure the second disk or plate 19 is done away with and each spring 21 is secured upon the disk or plate 15 and the tension of the spring adjusted by means of two screws 21, one on each side of a wedge-shaped projection 21, against which the attached end of the spring 21" presses.

22 is a handle having the lnil) which is secured by a set-screw 23 on the outer end of the sleeve 12, to turn said sleeve and magazine thereon as desired.

it is a pin secured to the handle 22 by a set-screw The ends of the lilling engage recesses in the periphery of the handle 22 and are wound around the pin .Z-t, as is customary.

I will now describe the mechanism for rotating the lilling-carrier magazine.

The sleeve 12 has a bevel-gear 26 fast on its inner end and in this instance integral therewith. The bevel-gear 26 extends within a recessed portion of the stand 7 and on the inner side of said stand (see Fig. 3) and is in mesh with and driven by a bevel-gear 27, which extends through an opening 7 in the stand T (see Fig. 1) and is fast on a shaft .28, having a bearing attached to a bracket 30, bolted to the stand T. (See Fig. 1.) The outer end of the shaft 28 is mounted in a bearing :31 on the upper end of a stand C51, bolted to a bracket 32, secured'to the loom-arch 9. (See Fig. 1.)

()n the shaft 28 is fast a bevel-gear 33, and a second bevel-gear 3t is loose on the shaft 28. A third bevel-gear is loosely mounted on a stud 3f), carried on the ratchet-wheel 37, and extends between and meshes with the two bevel-gears 33 and 3- The ratchetwheel 37 has a hub loose on the shaft 28 and has a checkwheel attached thereto, which is engaged by a roll 38 on an arm 38", actuated by a spring 38' (See Fig.

The ratchet I)? is adapted to be rotated by a pawl 32), pivoted by a pin 39 on one end of an angle-lever to, which is loosely mounted on the shaft 28. The other arm of the anglelever sh) is pivotally connected to the upper end of a vertically-moving rod or connector 11. The lower end of said rod or connector is attached to one end of a lever 42, pivoted at $3 on a stand t?) and having a circular portion thereon. adapted to be engaged by a cam AE on the bottom shaft to (see Fig. 1) when said lever $2 is released by the disengagement of the hook end 46 on the lever 46, fast on the rock-shaft LT. (See broken lines in Fig. 1.) Also fast on the rock-shaft t? is an arm or lever 48, the outer end of which is connected with the lower end of the connector or rod 4). In this instance the rod t9 extends through a hole in said lever 1th? and has l l i l l i a nut 50 thereon to engage the upper side of said arm. A spiral spring 51 encircles the lower end of the rod 41) and bears against a nut adjustable thereon and the lower side of the arm 7L8. The upper end of the connector *9 is pivotally connected to the supporting-arm 53' of the transferrer The supporting-arm 53' has a hub fast on a rockshaft 53" and is bent to extend through an opening 7' in the stand 7 within the magazine (see Fig. 2) and support the transferrer 53, which extends above and is adapted to engage thelowest bobbin 1.8. (See Fig. 3.) The transferrer extends within the magazine beyond the bevel-gear 26, as indicated by broken lines in Fig. 1. The downward movement of the transferrer when acting to transfer a bobbin 18 from the magazine into a shuttle in the usual and well-known way will, through its supporting-arm 53', move down the connector 4.0 and arm 48 and rock the shaft 47 and cause the lever 46 to be disengaged from the lever 12, releasing said lever from its normally inoperative position and allowing it to drop and to be engaged by the cam 4A, which as it revolves will raise said lever and through the connector-11 operate the pawl 39 to cause it to engage and rotate the ratchet-wheel 37 and through bevelgear 35, meshing with and turning bevel-gear 33, rotate the shaft 28, and through bevelgears 27 and 213 rotate the hub 12, carrying the filling-carrier magazine a certain distance to bring a fresh bobbin into operative position over the running shuttle.

()n the shaft 28 is fast a check-wheel 5-.t,having depressions in its periphery to receive a roll on a pivoted arm 56, which is actuated by a spring 57 to hold the roll in engagement with the check-wheel 5st (see Fig. 3) and prevent an accidental rotation of the shaft 28 or parts connected therewith.

I will now describe the mechanism for rotating the filling-carrier magazine in case it is provided with a series of colors, the corresponding colors being arranged in the different divisions of the magazineaccording to the colors in the drop-shnttle boxes, so that the raising and lowering of the drop-shuttle boxes will cause the rotation of the magazine a sullicient distance to always bring the proper color in position for the action of the transferrer.

The bevel-gear 3. which is loose on the shaft 28 and in mesh with the be\ 'el-gear 35, has in this instance teeth on its periphery which are engaged by the teeth on a longitudinally-moving rack-bar 58, which extends over the gear 33s. (See Fig. 6.) The rack-bar is moved by a rod 5%), which is attached to a longitudinally-moving rod 61), having bearings (51. The rod to has a link 61), adjustably connected thereto at one end, with its other end connected,through an angle-lever 62,with a rod (33, :nljustably attached at its lower end to a lever (HE, pivoted at ()5. The lever 61: is

IIS

connected, through a rod 66, with the vertically-moving box-rod 67, carrying the shuttle-boXes. (Not shown. See Fig. 5.) The vertical movement of the box-supporting rod 67 will, through the connection to the rackbar 58, move said rack-bar in one direction or the other and, through gear 34, will rotate the bevel-gear 35 and the bevel-gear 33 to turn the shaft 28 and, through bevel- gears 27 and 26, turn the sleeve 12 of the magazine carrying the filling carriers or bobbins 18 to bring into position to be operated on by the transferrer a bobbin of a color corresponding to the color of the bobbin in the shuttle-box to be thrown through the shed, as will be understood by those skilled in the art.

The operation of my improvements will be readily understood from the above description in connection with the drawings.

It will be understood that the details of construction of my improvements may be varied, if desired.
