SHUTTLE-MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 339,239, dated April 6,1886.

Application filed October 22,1884. Serial Nod-16,231. (No model.)

To all whom, t may concern:

Be it known that I, Tnnononn A. WEBER, of New York, in the county of New York and the State of New York, have invented a certain new and useful Improvement in Shuttle- Motions for Looms, of which the following is a specification.

I will describe a loom embodying my improvement, and then point out the improvement in claims.

In the accompanying drawings, Figure l is a plan view of parts of a loom embodying my improvement, and Fig. 2 is a front elevation of the same. A

I have deemed it necessary to illustrate only such parts of a loom as embody my improvement. Other necessary parts of the loom may be of any approved type.

A designates two side pieces, comprised in the frame of the loom.

B designates a shaft, which transmits -motion to the parts which embody my improvenient, and which I am about to describe. This shaft is journaled in the side pieces, A, and driven in any suitable manner. Near the side pieces, A, the shaft B has amxed to it bevel gear-wheels c c. rlhese bevel gear-wheels mesh with other bevel gear-wheels, b b, which are rigidly secured to vertical shafts O O. As here shown, these shafts C C are supported in bearings in inwardly-projecting brackets c c', attached to the side pieces, fA. At the upper ends the shafts O C have disks c2 c3 affixed to them. These disks have upon their under sides hubs c4 c5, which rest upon the inwardlyprojecting brackets c c of the side pieces, A, and support the shafts vertically.

D D designate levers, fulcrumed at the rear ends to pins or studs p p, supported by pro- 40 jections from the side pieces, A. These levers are swung to and fro to impart motion to the shuttles.

Motion is transmitted to the lever D by means of a crank-pin, E, projecting from the disk cI of the shaft C, a link-connection being employed between the wrist-pin and the lever. As here shown, the crank-pin has loosely fitted upon it a bar, d, and links d d2 are pivotally connected to the latter and to the lever D. By these means I am enabled to produce dwells77 of the lever at the ends of its movements, because the crank-pin E at certain portions of its stroke will not impart any appreciable swing to the levers D D on their fulcra. The front end of the lever D is pivotally connected to one end of a link, d, which at the other end is pivotally connected to a carriage, F. The carriage F is reciprocated along ways or guides Gr by the to-and-fro movements of the lever D. As shown, the side edges ofthe carriage work in grooves in the ways or guides. The ways or guides are secured to the side pieces, A.

H H are levers, which are fulcrumed between the ends upon studs f f, projecting from the carriage F near its forward end, or, in other words, near the end which is the nearer to the middle of the loom. The forward ends of the levers H H are adapted to grip the shuttles which are employed in the loom. To adapt the loom for using two shuttles, the forward ends of the levers are bifurcated, or, in other words, severally have two portions, f" f3, one above the other. Nearthe rear ends 'the levers H H are provided with longitudinal slots s. Passing loosely through the slots s are screws or pins f* f, projecting from the end portions of a bar, f, which is affixed to the upper end of a vertical rock-shaft, f7.

W'hen the shaft j" is rocked into a position at about right angles to the length of the levers H H', these levers will be forced as far apart as possible at their rear ends, and consequently as close as possible together at their forward ends. The forward ends will then grip shuttles inserted between them. At the lower end the shaft f i has affixed to it an arm, f8. By shifting this arm f8 the shaftf7 will be rocked, so as to operate the levers I-I H.

The lever D is connected to a crank-pin, E', projecting from the disk c3 of the shaft C, and derives its swinging motion from such crankpin. It is connected to the said crank-pin by means of a bar, d, loosely mounted on the crank-pin, and having a pivotal connection with links d d?, which are also pivotally connected with the lever D. This bar` d and the links d di are used in the same way and for the same purpose as the bar and links similarly lettered, which I have heretofore described.

The front end of the lever D is pivotally connected to one end of a link, di, which, at the other end, is pivotally connected to a car- IOO riage, F. Then the lever D is oscillated or swung to and fro, this carriage is reciprocated correspondingly along ways or guides G', which may be'similar to the ways or guides for the carriage F.

H2 H3 designate levers arranged u pon the carriage F'. They are like the levers H H',which are arranged upon the carriage F. They are fulcrumed upon studs fgfw, projecting from the carriage F', near the forward end of such carriage, or, in other words, near the end which is the nearer to the' middle of theloom. The Yforward ends of the levers H H3 are adapted to grip the shuttles. In order that two shuttles may be used, the forward ends of these levers are bifurcated, each having two portions, f f, one above the other. Near the rear ends the levers H2 H3 have longitudinal slots s, into which extend screws or pins fif, projecting from abar, f. This barf15 is affixed to the upper end of a vertical rockshaft, fm, which is journaled in the carriage F', and has affixed to itslower end an arm, f. By shifting Vthe arm f the rock-shaftfl will be rocked, and the bar f will oscillate the levers H2 H in such manner that the forward ends of the latter will alternately approach and recede from each other to grip and release the shuttles.

The movementsof the carriages F F' are so timed that they will approach each other and recede from each other together. The motions of the pair of levers H H', mounted on the carriage F, and of the pair of levers H2 H3, mounted on the carriage F', are so timed that when the carriages move into proximity the forward ends of one pair of said levers will move apart and the forward ends of the other pair of said levers will move toward each other, wherefore when the carriages come close together the shuttles will be transferred from one carriage to the other.

In order that the shuttles may always be transferred from one carriage to the other every time the carriages move into proximity with each other, it is necessary that the forward ends of the pair of shuttle-gripping levers of each carriage shall move together on one occasion when the carriages move into proximity, and move apart on the next occasion when the carriages move into proximity, and so on alternately.

I will now describe the means whereby the shafts f 7 f 1G are rocked for the purpose of operating the Shuttle-gripping levers H H' and HZ H3.

I I designate levers which are fulcrumed between theY ends to bars G2 G3, extending between the ways or guides G G'. These levers work in the same horizontal plane as the arms f B f, which are affixed to the shafts f7 fm. Then the carriages move into proximity with each other, the arms fS f1T come in contact with the levers I I', and are shifted so as to rock the shafts f7 f1, because the levers I I will at those times be adjusted at such angles that the arms f8 f 17, by abutting against them, will be shifted properly.

The levers I I' are connected together by a link, I2. The lever I has upon its under side lugs z', in which a rod, I3, ts in such way,

that while any swinging movement which may be imparted to it will be transmitted to the lever I, yet it will be free to slide lengthwise ofthe lever I. This rod I3 is pivotally connected to a lever, I4, which is pivotally connected by a link, I, with a crank pin, I, projecting from a gear wheel, J. The gearwheel J is mounted on a shaft which is supported by one of the side pieces, A, of the frame. It derives motion from a gear-wheel, J', having one-half the number of teeth which, it has, and affixed to the shaft C. 'Each time the shaft C makes fadcomplete rotation it moves the carriage F as far toward the carriage F as it can go. The shaft C at the same time moves the carriage F' as far toward the carriage F as it can go. During each rotation of the shaft C the gear-wheel J makes only a half-rotation. Owing to this the wheel J will shift the levers I I into a different position during each one-half rotation it makes. It is because the levers I I occupy a different position each time the carriages F F' move into proximity that the forward ends of each of the pairs of shuttle-gripping levers HH'and H2 H3 will move toward each other one time when the carriages move into proximity, and move away from each other the next time the carriages move into proximity, and so on.

The shuttles are to have grooves in thesides, into which the portions f2 f3 of the levers H H' and f u f 12 of the levers H2 H3 will t.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of carriages provided with pairs of shuttle gripper levers, guides for said carriages, means, substantially such as described, for reciprocating said carriages, oscillating bars connected with the said shuttlc-gripper levers, arms connected to the said oscillating bars, so as to move in unison therewith,V movable levers for shifting the said arms,and mechanism,substantially such as described, having a connection with one of said levers,which will enable it to be caused to act nearer to or farther from the fulcrum of said lever, substantially as specified.

2. The combinatiomwith carriages provided with pairs of shuttle-gripper levers, of guides for said carriages, means, substantially such as described, for reciprocating the carriages, bars provided with projections engaging with the said shuttle-gripper levers, rock-shafts, to which said bars are affixed, arms affixed to said rock-shafts, movable levers, by contact with which said arms are shifted to operate the said shuttle-gripper levers, and mechanism, substantially such as described, for shifting the said movable levers, substantially as specied.
