SHUTTLE-BOX-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 350,307, dated October 5, 1886.

Application filed November 5, 1885. 7 Serial No. 181,902. (No model.)

To all whom it may concern):

Be it known that I, EM'IL HONEGGER, of the town of Union, county of Hudson, State of New Jersey, have invented an Improvement in Shuttle Box Operating Mechanism for Looms, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which Figure l is a side elevation, partly in section, of that portion of a loom which contains my improvement. Fig. 2 is a side elevation, partly in section, of part of a loom, showing my improvement, the linec 0, Fig. 3, indicating the plane of section. *Fig. 3 is a horizontal section takenon the line k k, Fig. 2. Fig. 4 is an enlarged vertical longitudinal section on theline c is, Fig. 2. V

This invention relates to improved means for bringing either one-of a series of shuttles into line with the shed of a loom; and it consists of the combination of devices, hereinafter specified, for moving a rack containing the series of shuttles to a greater or less height,as required. In the drawings, the letter A represents the u vertically-movable rack which contains the series of shuttles.

In this illustration I have shown three shuttlesB, G, and Din the rack.

a and b are the warp-threads which form the shed.

In Fig. 1 the upper shuttle, B, is shown aligned with theshed so that it can be thrown to carry its thread into the fabric. The rack Ais suspended by two belts or cords, d and e, from a shaft, E, which has its bearings in the frame F of the loom.

Fig. 1, showing the uppermost shuttle, B, in line with the'shed, represents necessarily the rack A in its lowermost position. When the shuttle G is to be used, the rack must be raised higher than it is shown in Fig. 1, until saidshuttle G is aligned with the shed. WVhen the shuttle D is to be thrown, the rack must be raised still higher until the shuttle D is aligned with the shed. Thus either one of the three shuttles can be brought into line with the shed to'be thrown, and my invention seeks to bring about the automaticmovement of the rack, by means of which either one of these shuttles can be broughtinto line with the shed and kept there as long as needed for producing a certain design, to bereplaced by any one of the other shuttles when that is necessary to be thrown.

I desire it understood that,although the invention is here shown asapplied to a loom having three shuttles, itcan, nevertheless, be used in a loom having only two, or on one having more than three, shuttles, the system shown being illustrative of the invention only.

The shaft E can be turned in one direction by a hook, G, (see Fig. 2,) and in the opposite direction bya hook, H. These two hooks are suspended pivotally from a block, f, which is connected by a strap, 9, with a lever, h, that connects by a rod, i,with a lower lever, I. To this lower lever, I, oscillating motionjs imparted by a cam-shaft, J, and by a spring, j. Rotary motion is imparted to the shaft J by suitable mechanism. The spring j is represented as connected to the upper lever, h, by

one end, its other end being attached to the ceiling of the room or other fixed support. By rotating the shaft J the levers I and h are oscillated, and thereby the block f is moved up and down between proper guides k, carrying with it the hooks G and H. Each of these hooks G H is, by a spring, I, sought to be crowded against that part of the shaft E which is provided with four (more or less) parallel- 'rods, m, between plates n.

By card mechanism, hereinafter to be referred to, either one or both of the hooks can be moved in gear with the shaft E. Thus in Fig. 2 the hook G is shown as bearing against the rods m, while the other book, H, is represented as being clear of said shaft E and of the rods m thereon. In the same Fig. 2 the blockf or slide is shown in the lowermost position. that when the block f is now raised, the hook G will turn the shaft E in the direction of the arrow 1, which is represented in Fig.2, and in so turning the cord or strap 6, which is fastened at its upper end to the prismaticportion o of the shaft E, is in part wound upon said shaft, thereby raising the rack A. The parts hereinbefore described and their movements are so proportioned that every upward stroke of the block f will, when it causes the hook G to turn the shaft E, cause the rack A to be raised by the strap 6 the distance of one shuttle from the one next below it. If the hook G It follows is out of gear with the rods m on the shaft E, as shown by dotted lines, Fig. 2, and in its stead the hook H, in gear with one of the rods m on said shaft, then every upward movement of the block f and hook H will turn the shaft E in the direction opposite that shown by the arrow 1 in Fig. 2, and here, again, the motion is such that the resulting downward movement of the rack A will be equal to the distance between two adjoining shuttles. provided the cord orstrap c is made use of in lowering said rack. In other words, therefore, if the rack A is in the position shown in. Fig. 1 and the shaft E thereupon turned by the hook G, the shuttle C will be brought in alignment with the shed. If afterward the shaft E is again turned by the hook G, the shuttle D will be brought in line with the shed. If thereupon the hook H is made use of to turn the shaft, by one stroke of said hook the shuttle G will again be brought in line with the shed, while the next stroke of the hook H in the same way, in engagement with one of the rods in on the shaft E, would cause the shuttle B to be brought back in alignment with the shed. The shaft E is prevented from turning of its own accord, or from being turned by the weight of the rack A and the shuttles thereon, by a brake, L. This brake is a T- shaped slide, of which the vertical portion moves in suitable guides on the frame F, while its straight-edged horizontal portion rests on two rods, 19, of which a number are arranged around the axis of the shaft E and at equal distances from one another and located be tween plates q, as shown. Four rods, 10, are so used whenever the prismatic portion 0 of the shaft E is four-sided, and also when there are four rods, m, for the hooks G H to engage with; but it is clear that, instead of four sides to the prism 0, said prism may have five or more sides, in which case the number of rods m and 1) would be correspondingly increased. The spiral spring r crowds the flat face of the brake L upon two rods 9 of the shaft E, and thereby prevents the said shaft from turning except under the positive influence of hooks G H; but when one of these hooks engages the shaft to turn it the brakeLwill be raised and its spring 1* contracted until two rods 12 are again placed under the brake, which will then hold the shaft in position.

If it is desired to move the rack A the distance of more than one shuttle, so as, for example, to bring the shuttle D into line with the shed after the shuttle B had been used, I make use of the strap (11, the upper end of which is attached toa prismatic block. .9, which is looselyswiveled on the shaft E. This loose condition of the block 3 prevents it being disturbed whenever the cord or strap 6 is used; but the block 8 can be locked to the shaft E by a slide, M, which moves on a prismatic part, t, of the shaft E, and which carriesaprojecting pin, a. When this pin is broughtinto a fork, c, that is carried by the block s, (see Fig. 3,) the block 8 will be locked tothe shaft E, so as to turn therewith, and will thus pull the rack A or lower it, according to the direction in which the shaft E is turned the distance of the shuttles B D from one another. The slide M is moved to lock or unlock the block .9 by the card mechanism hereinafter de scribed. The blocksis a prism so much larger than the prism 0 that it will,whenever turned, move the rack twice as far as the same movement of the shaft E will cause said rack to be displaced by the strap a.

Having thus shown what will take place with reference to the position of the rack A whenever the shaft E is turned by one of the hooks G H, it remains to show how the hooks G H are brought into action, how they are;

kept in action for any length of time, and how the slide M is moved.

N is a chain of cards, which is placed round two rollers, w and w, and which is to control the position of the hooks G H and slide M. This chain is moved intermittently by a hook,

to, which is provided to a lever, b that is connected by a cord or strap, (1", with the lever I. Whenever the lever I is moved downwardly, it will cause the hook to to move down,too; but whenever the lever I moves upwardly thehook a" and lever I) are moved upward by a spring, 6 The book a engages a ratchet or studded wheel, f, on the roller it), so that during its downward movement the said hook will turn. the roller w, and thereby the chain of cards, at least whenever the said hook is held by an appropriate spring, 9 in contact with the wheel f but I have contrived means, which I shall hereinafter describe, for throwing the hook it off the wheel, as in Fig. 2, in which case the chain N will remain stationary.

I have represented in Fig. 3 four hangers or suspended bars, h, 5 ,3 and Z, in line with the chain N, so that either one or more of said hangers, all of which are pivoted at m to the stationary frame of the loom, can be moved out of their vertical position by pins on the chain N. I will first describe how these hangers affect the position of the hooks G'I-I. The hanger j is connected by a horizontal rod, M, with another hanger, 0", which is pivoted to the frame F at P2. (See Fig. 2). The hooks G H, it will be seen, are suspended from the block f, midway between the hangers j and 0 The hanger 0 connects by a link, q, with a lever, a, which carries a rod, 3, on the end of which is a loop, 8", that embraces the shank of the hook H. WVhenever the pin on the chain N' pushes the hanger j awayfrom the card, the ban ger 0 is, by the rod a, pushed into the inclined position shown in Fig. 2, thereby causing it to swing the lever 1" with the upper end toward the hook H, and to push the rod .5: toward the chain N. This motion of the rod 8" causes its loop to carry the hook H into the inclined position, which is shown by full lines in Fig. 2. Thus the hook H is carried away from the shaft E and'out of engagement with the rods on the same. By the spring-connection Z with the hook G. the hook.

IIO

H draws the hook 5; toward the shaft E, as in Fig. 2, if the hook G is not otherwise prevented from approaching said shaft. Hence it follows that whenever the chain of cards swings the hanger j -and none of the other hangers near it, the hook H will be moved out of engagement and the hook G into engagement with the rods on shaft E. As soon as the card ceases to effect the hanger j the same drops under the influence of its own weight, assisted, if desired, by asuitable spring, into a vertical position, which is sufficient to cause the hook H to be released from the action of the loop 8 and to drop into the dotted position shown in Fig. 2, where, however, it is still out of engagement with the rods on shaft E. The hanger i connects with a rod, V, which carries a loop, i that embraces the shank of the hook G. Therefore,when the hanger i is moved by the card, the loop t carries the hook G away from the shaft E, yvhich motion, by the connecting-sp ring Z, causes the hook H to be drawn into engagement with the shaft E. Thus whenever the card moves only the hanger i the hook H is drawn into engagement with the rods on shaft E andthe hook G out. of engagement. When the hanger i is unaffected by the card, it holds by the loop t the hook G, in the dotted position represented in Fig. 2, where it is still out of engagement with the rods on shaft E. In other words,-when both hangers 2' and 9' are unaffected by the card, both hooks G and H will-be in the dotted position shown for them in Fig. 2, out of engagement with the shaft E, so as not to influence the same in any way during their reciprocating movement with the block f. I have thus shown how the hooks G and H can be thrown alternately into engagement with the rods on shaft E, and how they are held out of engagement when required.

I will now show how the cards affect the position of the slide M for the purpose of throwing the block 8, which carries the strap d, into and out of gear. Fig. 1 shows that the ends of the slide M bear against the inner sides of two hangers, O P, that are pivotally suspended at n and o from the stationary frame F, and that are connected together by a rod, w so that when one of them is moved the other will move in the same direction and to the same extent. The hanger O, which is also shown in section in Fig. 3, connects with a lever, Q, which by a link, at, is connected with a hanger, 3 which at p is suspended from the frame F. By a rod, a the hanger is connected with the hanger Z Whenever the card pushes the hanger P, the same will,by the horizontal rod a swing the hanger 3 in the same manner, and will thereby cause the lever Q to draw the hanger O in the direction toward the hangery*. The hangers O P moving together, it follows that by this motion the slide M will be moved to carry its pin it out of the fork 1;, thereby disengaging the block 8 and leaving it freely swiveled on the shaft E. When, however, the card leaves the hanger Z undisturbed,

versed.

a spring, b will draw the hanger 0 toward the shaft E, thereby moving the slide M so as to carry its pin a into engagement with the fork cand lock the block sto said shaft. Of course the arrangement stated may be variedor re- Thus, for example, the fork o and pin it may be on the opposite side of the shaft E, so that the block 8 will be thrown into engagement with theshaft E when the hanger Z is disturbed by the card, and held out of engagement when said hanger is left undisturbed by the card. V

It remains to show the mechanism I have devised for holding the chain of cards N im- This movable for a suitable length of time. isfor the purpose of permitting the use of one shuttle for any period of time. For example, if a design to be woven provides for the use of several shuttle-threads of a given color. in

succession, it is desirable to lock the chain of cards N during. this throwing of the same shuttle and not unnecessarily to move it. For this purpose I have placed near the hook a which, as has been already shown, moves the card N, a pivoted cam, (1 which is represented by dotted lines in Figs. 1 and 2, and which has its edge made partly flat and partly circular. When the flat edge of this cam is aligned with the shank of the hook a as in Fig. 1, the said hook will be in engagement with the wheel to move the chain of cards N; but when the circular part of the cam d is in contact with the shank of the hook at, as in Fig. 2, then the hook will be held away from the wheel f and will not be able to move the chain of cards N. The cam d carries on its face as many equidistant pins, 6 as correspond to the number of shuttle-threads of the same color to be thrown in succession, and in lieu of these pins, as an equivalent, a ratchet- ,wheel on the cam d may be used. f is apawl pivoted to the lever 12 and normally held out of engagement with the said ratchet-wheel or pin-wheel e by a spring, 9 (see Fig, 1;) but when the cam d is to be turned to render the chain of cards N stationary the hanger h is moved by a pin on the cards and carries a'yoke, h against the pawl f so as to crowd that pawl into engagement with one of the pins or ratchet-teeth,as in Fig. 2. When, now, the lever I is oscillated, the lever btwill cause the pawl f to turn. the pin-wheel or ratchet-wheel c and with it the cam d so as to crowd the book at out of gear, as in Fig. 2,- and stop the movement of the chain of cards N. The cards will remain thus arrested until the straight edge of the cam d is again in 1.
