To 1/] whom it nuty concern.-

Be it known that I, EPPA H. RYoN, a citizen of the United States, residing at \Vorcester, in the county of orcester and State of Massachusetts. have invented certain new and useful Improvements in Narroware Looms, of which the following is a specification.

My invention relates to narrow-ware looms or looms for making ribbon, tape, &c.,in which two or more banks of shuttles are used; and my invention particularly relates to looms for weaving ribbon, tape, &c., with two or more different colors or different sizes of yarn.

The object of my invention is to improve upon the construction of narrow-ware looms of the class referred to as ordinarily made.

My invention consists in certain novel features of construction of my improvements, as will be hereinafter fully described.

I have only shown in the drawings suflicient parts of a narrow-ware loom with five banks of shuttles of the class referred to to enable those skilled in the art to which myinvention belongs to make and use the same.

Referring to the drawings, Figure 1 is an end view of a loom-frame and of myimprovements combined therewith looking in the direction of arrow (1, Fig. 2. (Some of the parts at the left are broken away.) Fig. 2 isa front view of the parts shown in Fig. 1 looking in the direction of arrow 7), same figure. Fig. 3 is a sectional view showing some of the parts shown in Fig. 2 detached. Fig. 4: is a section on line 1 at, Fig. 3, lookingin the direction of arrow r, same figure. Fig. 5 shows some of the parts shown at the left in Fig. ldetached. Fig. 6 is a front view of one end of the layframe, showing partially in section the shuttle-rails, the gears, and the racks for moving the shuttles, looking in the direction of arrow 1/, Fig. 7; and Fig. '7 is a section on line 7 7, Fig. 6, looking in the direction of arrow 6, same figure. Figs. 3 to '7, inclusive, are shown on an enlarged scale.

In the accompanying drawings, 1 is the loom side or frame.

2 is the upper cylinder-gear, 3 the lower cylinder-gear, 4 the vibrator-gears, 5 the vibrator-lever, operated by the pattern- chain 5, and 6 the vibrator-connectors, of the well- 5 known Knowles head-motion shown and described in United States Letters Patent No. 131L992. The vibrator-connectors 6 (three in number) are in this instance connected with three levers 7, 8, and 9, pivotally mounted on a stud 10. The lever 7 is of angle shape and is connected by a link 7' with one arm of an angle-lever 7", pivoted at 11 on one arm of an angle-lever 8. The other arm of the anglelevcr T is pivotally connected with a stud 12. The lever 8 has pivotally mounted on its lower end at 8 an angle-lever 8', one arm of which is connected by the link 9 with one arm of the angle-lever 9, pivoted on the stud 10. The other arm of the angle-lever 8 carries 5 the stud 11, on which is pivoted the angle-lever 7", as above stated. By means of the three lovers 7, S, and 9 are given through intermediate mechanism the live positions as ordinarily required in a five-slnittle-box loom. 7 Said three levers T, 8, and 9' are in this instance used to raise and lower the shuttlerails, mounted on the lay-frame in any usual way and carrying the narrow-ware shuttles and their operating racks and pinions into five different positions and also to connnunicate to the shuttles a longitudinal movement correspomling to said positions, as will he hereinafter described. In the drawings I have shown one position of the three levers 30 T, 8, and 9 and their eomwctions, which position gives to the shuttle-rails the fourth position, or the second position from the. highest position, and moves the second row of shuttles from the bottom by their operating 5 mechanism to weave in the fabric the color carried by said shuttles.

The stud 12 is that part of the mechanism which has communicated to it through the levers 7, 8, and 9 five different positions, and 9 said stud 19. is connected through intermediate connections with the shuttle-rails to communicate to them the five different positions communicated to said stud 12. The stud 12 is connected by a link 13 with one arm of a lever 1 1, centrally pivoted on a stud 15. The

stud 12 is also connected by a link 16 with the upper forked end 17 of a lever 17, pivoted at its lower end on a bracket 18. The forked lever 17 engages and operates a yoke 19' in a grooved collar 19, fast on the sliding shaft 20, which shaft has fast thereon the two partial gears 21 and 22, having teeth thereon, and also the plain portion or dwell-section, and also has fast thereon the two check or dwell drums 23 and 24, which extend over the live cams 25, 26, 27, 28, and 29, loosely mounted on the stud 30. The gear 21 is adapted to engage and rotate the four cams 25, 26, 27, and 28, while the gear 22 is adapted to engage and rotate the cam 29. Each of the cams 25, 26, 27, 28, and 29 are in this instance provided with four separate series of teeth on their periphery (see Fig. 3) and an intermediate plain portion or dwell-section, which is concaved to engage theconvex surface of the drum- wheels 23 and 24. The operating- gears 21 and 22 are provided with enlarged teeth at each end of the teeth thereon which mesh with the teeth on the cams, and said enlarged teeth engage the ends of the plain portions on the cams to commence to rotate the cams. Through the rotation of the live cams 25, 26, 27, 28, and 29 the proper movement is communicated through intermediate mechanism to the live banks of shuttles to correspond with the movement of or the raising and lowering of the shuttle-rails carrying the shuttles. Each of the cams 25, 26, 27, 28, and 29 has a cam-groove 31 therein, (see Fig. 3,) which receives a roll 32' on a lever 32, pivoted on a rod 33. The lower end of each lever 32 is connected by a connector 34, adjustable as to its length with the lower end of a lever 35. Each lever 35 preferably has a stud 35 at its lower end, which is detachably connected with an open-end slot 34 at the end of the connector 34, so that the connectors 34 can be readily disengaged from the levers 35 for any purpose.

Each lever 35 has a longitudinal slot 35 therein, through which extends a rod 36, which forms the pivot of the levers 35. The rod 36 extends at each end into and is adjustablyheld in a vertical slot 37 inthe two uprights 37, connected at their upper ends with the end of the shuttle-rails or the sheave-frame. The lower ends of the uprights 37 are fast to the cross-bar 37", having a stud 37 On the pivot-rod 36 are collars 36 to hold the levers 35 in their proper position thereon. The upper end of each lever 35 is connected by a link 38 with a block 39, supported and having a reciprocating movement between the bars 39. Each block 39 has attached thereto a strap 40, which passes around four pulleys or sheaves 41, suitably supported, and has each end secured to an extension 42 on a rackbar 43 to communicate a longitudinal motion to said rack-bar in each direction and through the pinions 44 (shown in Fig. 6) communicate a motion to the shuttles 45 to cause them to thereon.

pass through the shed in front of the reed 46, carried on the shuttle-rails, in the usual and well-known way.

Cords 48, connected at one end to the connectors 34, pass over pulleys 49 on a stud 50 on a stand 51 and are attached at their other ends (not shown) and furnish means for the operator to raise'each connector 34 and disengage it from its lever 35.

The shaft 20, carrying the cam-operating gears 21 and 22, has a rotary motion communicated thereto through a gear 52, splined on the shaft 20 to allow said shaft to slide through it, and driven by a gear having a bevelgear 53 attached thereto and in mesh with a bevel-gear54, fast on the lower end of an upright shaft On the upper end of the shaft 55 is a bevel-gear 56 in mesh with a bevelgear 57 on the face of a gear 58 on a stud 59. The gear 58 is in mesh with a gear 60, driven by a gear 61, fast on a shaft 62, mounted in a sleeve 62 and carrying the driving-belt pulley 63 and the pulley 64, loose on said shaft 62, which receives the d riving-belt (not shown) when it is shipped from the fast pulley 63.

Referring now to the centrally-pivoted lever 14, already described, the other arm of said lever is connected by a link 68 with an arm 69, fast on the rock-shaft 70. At the end of the rock-shaft 7 O is fast an arm 71, which is pivotally connected by a stud 71 with the upper end of a link The lower end of the link 70 has a hole therethrough to receive the stud 37 on the bar 37. The outer end of the stud 37' extends into and is guided by a vertical slot 72 in the stand '72. (See Fig. 1.) Also fast on the rock-shaft 70 is one of a series of arms 73, pivotally connected at its outer end with the lower end of a connector or rod 74. The upper end of the connector 74 is pivotally connected with a stud 74 on a collar 75, adjustably secured by a set-screw 76 on the rod 77, which is secured at its upper end to the lower side of the shuttle-rails and extends at its lower end through a guide or bearing 78, secured to the lay-sword 79,

which is pivotally mounted at its lower end and carries at its upper end the lay 79.

A connector 80, attached to the lay 79 at one end and to a crank (not shown) at its other end in the well-known manner, communicates a swinging motion to the lay and the shuttlerails from the crank on the driven shaft 82 in the usual way. A gear 83, fast on the shaft 82, meshes with a gear 84 and through gear 85 drives the upper cylinder-gear 2.

From the above description, in connection with the drawings, the operation of my improvements will be readily understood by those skilled in the art, and briefly is as followsz'As the pattern-chain 5 revolves the three compound levers 7, 8, and 9 are moved, according to the indications of the pattern-surfaces, through the vibrator-levers 5, the vibrator-gears 6, and the connectors 7, operated by the upper and lower cylinder-gears 2 and 3 in the usual way. The movement of the three levers T, 8, and 9, according to the indications of the pattern-surfaces, is cmnmunicated to the stud 12 to move said stud into five ditfcrent positions. The movement of the stud 12 is communicated through intermediate connections, consisting of the link 13, lever 1%, link 68, arm 69, rock-shaft TO, and arms fast on said rock-shaft, to give an up-anddown motion to the shuttle'rails and the shuttles and their operating mechanism to bring each of the live rows of shuttles at the proper time into a position at the front of the reed to carry the lilling through the shed. At the same time the movement of the stud 12, through the link It), lever 17, sliding shaft 20, the par tial gears 21 and 22 are moved into position to engage and rotate one of the cams 31, to cause, through intermediate mechanism, consisting of the levers 32, connectors 3a, levers 35, link 38, and blocks 39, a reciprocating movement to the belt a0, attached to the rackbars is), to cause a longitudinal motion of each nick-bar, to operate the row of shuttles which is in position in front of the reed, to carry the filling through the shed.

The advantages of my improvements will be readily appreciated by those skilled in the art.

I employ the well-known Knowles headmotion" ordinarily used for operating the shuttle-boxes, for raising and lowering the shuttle-rails, carrying the shuttles and their operating mechanism, and for moving the racks to operate the pinions to move the shuttles. Ihave shown in the drawings five .banks of shuttles; but it will be understood that two or more banks of shuttles may be used.

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

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
