MECHANISM FOR OPERATING DROP SHUTTLE-BOXES IN LOOMS.

SPECIFICATION forming part of Letters Patent No. 414,366, dated November 5, 1889.

Application tiled December 22, 1885. Serial No. 186 ,484. (No model.)

To all 1071/0121, it may concern.-

Be it known that LEDWIN BARTON, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Mechanism for Operating Drop Shuttle-Boxes in Looms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to the employment in a loom of a Jacquard machine, which is made to control both the harness motion and the movements of the shuttle-boxes to produce the changing of shuttles.

In carrying out my invention I employ for giving motion to the shuttle-boxes all of the mechanism employed in the well-known Knowles loom, now in extensive use, such mechanism being described in several United States patents granted to Lucius J. Knowles, and particularly in his patents, No. 37,760, dated February 24,1863, and N0. 134,992,dated January 21, 1873; but instead of employing a separate pattern-chain to control the movements of what are termed in the Knowles loom the vibrator-levers, which carry what are known as the crank-gears, I employ mechanism through which the said levers are connected with the Jacquard machine, and it is this last-mentioned mechanism which constitutes my invention. I

Figure 1. in the drawings represents a side elevation of a loom having my invention applied. of the loom on which the shuttle-box motion is applied. Fig. 3 is a side view, on a larger scale than Figs. 1 and 2, of the mechanism through which the Jacquard machine controls the vibratonlevers. Fig. iis a rear elevation, and Fig. 5 a plan corresponding with Fig.3. Fig. 6 is a side view of one pair of the compound levers for operating the shuttie-boxes.

Similar letters of reference indicate corresponding parts in the several figures.

A designates the loom-framing, B the lay, and C one set of shuttle-boxes.

I) designates the crankshaft, having fast upon it, outside of the loom-framing, the crank a, for operating the Jacquard machine, and the spur-gear b, for driving the shuttlebox motion. The gear 1) gears directly with the spur gear c, which is fast to the lower cyl- Fig. 2 is a rear elevation of that side inder-gear cl, and also gears, through an intermediate gear (2*, with the spur-gear c, which is fast to the upper cylinder-gear d, and by these means constant rotary motion is imparted to the two cylinder-gears cl d in the directions of the arrows respectively marked upon them in Fig. 1.

E E designate the crank-gears arranged between the upper and lower cylinder-gears, where they are supported in the vibrator-1evers F F, their cranks e, of which only one is shown, (see Fig. 1,) being connected by the connectors f f with the upper ends of the compound levers G G, the lower ends of which are connected by cords g with the posts 0 of the shuttle-boxes.

H is the locking-lever for holding the vibrator-levers F during the pick of the shed which has been set. It is the cam fast on the lower cylinder gear (I, for, the purpose of throwing off the said locking-lever to permit the movements of the vibrator-levers by the Jacquard machine.

All the parts above described are precisely the same as in the well-known Knowles 100111 with drop shuttle-boxes, now in common use, and substantially as represented in the patents of Lucius J. Knowles, hereinbefore referred to, and therefore I only describe them sufficiently to enable me to intelligently describe the nature aud operation of my own invention, which I will now proceed to describe in detail. On that side of the loom from which the Jacquard machine is worked and on which the shuttle-box motion is situated there is erected on the side frame a standard A, and in this standard is secureda stud 2', on which turn freely a number of ratchet-wheels I I corresponding with the number. of vibrator-levers F F, eachof the said wheels having four teeth and as many intervening straight edges, and each having secured to it a cam "21, which is of the form of a circle with two opposite segments removed,

thus making two offsets, as shown in dotted outline in Figs. 1 and 3. In the same standard A are also secured three fixed studs j kl, which serve as the fulcra of three sets of le ve'rs J K Leach set corresponding in number with the wheelsI and cams t" and with the vi brator-levers F. The levers J are furnished with hook-pawlsj for turning their respect ive ratchet-wheels I, and so turning the cams 'i, the purpose of which is to raise and lower the levers L, which I call lifting-levers, and which are connected bywires or cords Z each with one of the vibrator-levers F of the Knowles drop-box motion for the purpose of operating the said vibrator-levers and their crank-gears. The levers K operate on the straight edges of the ratchet-wheels I for the purpose of preventing them from being turned more than a quarter-revolution by the pawls and keeping the cams t" in the proper positions of rest to so support their respective vibrator-levers as to allow the crank-gears E severally to engage at the proper times with the upper and lower cylinder-gears d d.

Springs 7' are applied to the pawls j, and

springs k are applied to the levers K to keep them in operative relation with their respective ratchet-wheels.

The levers J, or as many of them as may be necessary, according to the number of shuttles to be used to produce the pattern, are connected with as many of the levers N of the Jacquard machine. In the example represented, although there are shown four sets of levers J K L and a corresponding number of vibrator-levers F, only two levers N are shown in the Jacquard machine, because, in order to avoid complication of the drawings, I have represented the pattern mechanism as set up to use only two shuttles for the pattern, and hence only two of the levers J are shown connected and in use. Each of the said levers Nis shown connected with a hook 917., which passes through one of the needles 01. Besides the two shuttles used for the pattern a third is used for the ground in the upper shuttle-boxes, provided in the Jacquard machine for controlling the shuttleboX motion, the movements of the said needles to place the said hooks in or out of range of the knives p of the lifting frame or grid Pot the Jacquard machine being controlled by holes and blanks provided in the same pattern-cards M as are commonly employed in the Jacquard machine for controlling the harness motion, the pattern-perforations for controlling said needles being in the portions of the cards near one end thereof, as may be understood by referring to the needles represented in Fig. 1;

The Jacquard machine being such as is commonly employed needs no particular description. It is represented in the drawings (see Figs.- 1 and 2) as worked from the crank a in the usual way by a connectingrod R and lever S, and as having the connections made in the usual manner between the lifting frame or grid P and the cords t t of the harness by means of the hooks m m under the control of the needles n n and the proper holes in the pattern-cards.

The levers J for operating the ratchetwheels I and cams i, when not raised by the Jacquard machine, are supported in proper positions of readiness to be operated upon by the Jacquard machine by resting upon the horizontal upper edge of the bracket J, secured to the standard A.

It will be understood that if all the gearing and connections of the shut-tle-boX-operating mechanism are properly adjusted the connection of that mechanism with the same J acquard machine which operates and controls the harness, the harness motion, and the shuttle-box motion cannot fail to operate in timely relation with each other.

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

1. The combination, with the Jacquard machine, the shuttle-boxes, the vibrator-levers F, the crank-gears E, mechanism, substantially as herein described, for producing the rotation of said crank-gears, and mechanism, substantially as herein described, whereby the cranks e of said gears are connected with the shuttle-boxes, of a series of lifting-levers L, connected with said vibratorlevers, a series of cams for operating the said levers, a series of levers, pawls, and ratchets for turning the said cams, and connections, substantially as herein described, between the last-mentioned levers and the Jacquard machine, all as herein set forth.

2. The combination, with the lifting-hooks m, needles n, and levers N of the Jacquard machine, and means, substantially as herein described, for operating said hooks and needles, the shuttle-boxes, the vibrator-levers F, and crank-gears E, carried thereby, and the connections f G G g between said gears and the shuttle-boxes, of the lifting-levers L and connections Z, the lifting-cams 2", the ratchetwheels I, attached to said cams, the pawllevers J and pawls j, for turning said ratchetwheels and cams, and the connections q between said pawl-levers and said levers N, all substantially as herein set forth.
