Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed May 27, 1905. Serial No. 262,633.

To all w/wm it may concern:

Be it known that I, BENJAMIN F. MCGUIN- ESS, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Loom Pattern-Chain Mechanism, of which the following is a specification.

My invention relates to that class of looms which are provided with a multiplier patternchain in addition to the box pattern-chain.

It will be understood that by means of the multiplier pattern-chain certain bars of the box pattern-chain of the drop-box indicating mechanism may be repeated without constructing successive similar bars in said box pattern-chain.

My present invention relates particularly to a supplemental mechanism adapted to be combined with any ordinary form of multiplier mechanism by means of which the movement of the box pattern chain may be stopped at any desired time and for any desired length of time, the rest-of the loom continuing to operate in the usual way.

The object of my invention is to provide a supplemental mechanism of simple construction and operation adapted to be combined with'a box pattern-chain mechanism and a multiplier pattern-chain mechanism of any ordinary construction and operation and which can be operated manually by the weaver or automatically to throw out of action the mechanism which operates the box pattern-chain, to stop the operation of said pattern-chain at any desired time and for any length of time, and to put into operation the box pattern-chain mechanism.

My improvements may be combined with any loom of the class referred to and is designed particularly for looms for weaving blankets, table-cloths, &c., in which there is a long plain weave between two borders.

In using my improvements I can adapt them to be operated manually by the weaver or to be operated automatically through connections to some driven part of the loom, and preferably to the driving mechanism for the measuring-dial.

I have shown in the drawings my improvements combined with a Well-known type of drop-box pattern-chain mechanism and multiplier pattern-chain mechanism operated by pin wheels and star wheels and such as shown and described in United States Letters Patent No. 413,369.

I have only shown in the drawings a detached part of the drop-box pattern-chain mechanism and the multiplier pattern-chain mechanism with my improvements combined therewith sufficient to illustrate the nature thereof.

Referring to the drawings, Figure 1 is a sectional front view of a box pattern-chain mechanism and a multiplier pattern-chain mechanism with my improvements applied thereto, taken at a point indicated by line 1 1, Fig. 2, looking in the direction of arrow a, Fig. 2. Fig. 2 is an end view of the parts shown in Fig. 1 looking in the direction of arrow 1), same figure. Some of the parts shown in Fig. 1 are not shown in this figure. Fig. 3 is a detached plan view of my attachment. Fig. 4 corresponds to Fig. 3, but shows a different position of some of the parts. Fig. 5 shows another position of some of the parts shown in Fig. 3, and Fig. 6 shows still another position of some of the parts shown in Fig. 3.

The drop-box pattern-chain mechanism and the multiplier pattern-chain mechanism (shown in the drawings) are of the usual and Well-known construction and operation and are fully shown and described in said patent, and therefore I will only briefly describe the same herein.

In the accompanying drawings,1 is a portion of a loom-frame.

2 is a stand on which are supported the several parts of the pattern-chain indicating mechanism. 1

3 is a shaft suitably supported.

4 is a sleeve mounted on the shaft 3 and having fast thereon the pattern-chain barrel or cylinder 5, having thereon the drop-box pattern-chain 6, made up of links and bars, said bars carrying rolls and tubes in the ordinary way.

Fast on the sleeve 4 is a star-wheel 7, which is adapted to be operated by a pin-wheel 8, the hub of which is splined on a shaft 9, driven through a gear 9, to rotate withsaid shaft and to move longitudinally thereon and carry the pin 8 on the pin-wheel S into and out of engagement with the star-wheel 7. The pin-wheel 8 has an annular groove 8 in the hub portion thereof, into which extends the forked end of an arm 10, (see Fig. 3,) mounted on a longitudinally-moving shaft 11, suitably supported. On the end of the shaft 11 is loosely mounted a collar 12, held on the shaft by a split pin 13. The collar 12 has a groove or recess 12 therein to receive one end of an angle or bell-crank lever 14, pivoted at 15 on a stationary rod 16. The other arm of the bell-crank lever 14 is pivotally connected to the lower end of a connector 17, and the upper end of said connector 17 is pivotally connected to an indicator-lever 18, which has a foot 18 thereon, which extends over the multiplier pattern-chain 19 (see Fig. 2) on the pattern-cylinder 20, which is loosely mounted on the shaft 3 and has connected therewith a star-wheel 21.

The indicator-lever 18 is pivotally mounted on an upright stand 22, secured to the frame or stand 2. (See Fig. 2.) The starwheel 21 is operated by a pin 23 on a pinwheel 23, splined on the driven shaft 9 and adapted to rotate with said shaft and move longitudinally thereon. The hub portion of the pin-wheel 23 has an annular groove therein to receive the forked end of an arm 24, having a hub portion 24 fast on a longitudinallyrlnoving shaft 25, suitably mounted. (See The shaft 25 has at its opposite end a collar 26, fast thereon, which has a recess or groove therein to receive one end of an angle or bell-crank lever 27. The bell-crank lever 27 is pivotally mounted at 28 on the rod 16. The opposite arm of the angle-lever 27 has pivotally connected thereto the lower end of a connector 29. The upper end of the connector 29 is pivotally connected to an indicator-lever 30, which is pivoted at 31 on the frame 1 and extends over indicating-surfaces on the drop-box pattern-chain 6, which surfaces are in this instance mounted on the projeoting ends of the bars forming a part of the pattern-chain. (See Fig. 1.)

. A spring 32, connected to the'projection 27 on the angle-lever 27 and to a stationary part of the frame, acts to move the anglelever 27 and the sliding shaft 25 and move the pin-wheel 23 through the arm 24 out of engagement with the star-wheel 21 when the indicating-surface passes from under the indicator-lever 30.

A spring 33, connected with a projection 14 on the angle-lever 14 and with a stationary collar 34, acts to move the angle-lever 14 and the sliding shaft 11 and move the pinwheel 8 through arm 10 out of engagement with the star-wheel 7 when a roll on the multiplier pattern-chain 19 passes from under the indicator-lever 18.

All of the above-described parts are of the usual and well-known construction and are operated in the usual and well-known Way.

I will now describe my improvements,

which form a supplemental mechanism and are in this instance combined with the parts above described and by means of which the pin-wheel 8, which drives the star-wheel 7 of the box pattern-chain 6, may be manually or automatically moved into its inoperative position at the time desired and held there, so that it will not operate the star-wheel 7, and consequently the box pattern-chain will remain at rest until the pin-wheel is released to allow it to operate the star-wheel 7 and the box pattern-chain.

On the sliding shaft 11 is mounted a spiral expansion-spring 35 intermediate the hub 10 of the forked arm-1O and the collar 12, both loose on the longitudinally-sliding shaft 11. A collar 36 is fast on the longitudinally-moving shaft 11 and is adapted to be engaged by the hub 10 of the arm 10 to limit the longitudinal motion of said hub on the sliding shaft 11. Extending down from the hub 10 of the arm 10 is a pin 10, on which is loosely mounted the hub 37 on one end of a link 37. The other end of the link 37 has a longitudinal opening 37 therein, through which is adapted to extend a pin 38 on a crank-arm 38, fast on the upper end of a rock-shaft 39, mounted in a stand 40, secured to the stand 2. (See Fig. 1.) On the lower end of the rock-shaft 39 is fast the hub 41 on an arm 41. The outer end of the arm 41 carries a pin 41", to which is pivotally connected one end of a connector 42. (See Fig. 2.) The other end of the connector 42 is pivotally connected in this instance to the lower end of a verticallyextending lever 43. The upper end of said lever 43 has a hub 43 thereon, which is pivotally mounted on a stationary rod 44.

The operation of my supplemental mechanism will be readily understood by those skilled in the art.

When it is desired to stop the movement of the box pattern-chain, the weaver moves thearm or lever 43 in the direction indicated by arrow 0, Fig. 2, and into the position shown in Fig. 2. The movement of the lever 43 through connector 42, arm 41, rock-shaft 39 crank-arm 38, and link 37 will move, through the hub 10 on the arm 10 and the spring 33 between said hub and the collar 13, the shaft 11 to the left, Fig. 1, and into the position shown to move the pin-wheel 8 out of engagement with the star-wheel 7. The loom will continue to operate; but the star-wheel 7 and the box pattern-chain will remain stationary.

In case a roll comes under the indicatorlever 18 of the multi lier pattern-chain 19, the shaft 11 being he d from endwise movement, the spring 33 on said shaft,through the raising of the indicator lever 18 and the movement of the bell-crank lever 14, will be compressed, as shown in Fig. 4, and the operation of the indicator-lever 18 will not be interferred with.

When it is desired to have the box patternchain operate, the lever 43 is moved in the opposite direction, (indicated by arrow (1, Fig. 2,) and throu h connector 42, arm 41, and rock-shaft 39 t e crank-arm 38 will be moved into its opposite position, (shown in Fig. 5,) in which position the link 37 is free to move longitudinally and with it shaft 11 to move the pin-wheel 8, through arm 10, into a position to operate the star-wheel 7, as shown in Fig. 6, when a roll comes under the indicatorlever 18 of the multiplier pattern-chain 19. The spring 33 is strong enough to hold the collar 12 and cause the shaft 11 to move longitudinally when the crank-arm 38 is not in position to hold the link 37that is, in the ordinary operation of the loom, the expansion-spring 33 will hold the hub 10 on the arm 10 and the collar 12 on the shaft 11 both in their proper relative positions, so that communication intermediate the box patternchain and the multiplier pattern-chain may be made in the ordinary way.

In case it is desired to have my supplemental mechanism operated automatically at predetermined times and for predetermined lengths of time the connector 42 may be connected with some driven part of the loomfor instance, the operating mechanism of the measuring-dial.

It will be understood that the details of construction of my improvements may be varied, if desired, and they may be used in connection with pattern mechanisms which have two or more pattern-chains.

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

1. In the pattern-chain mechanism of a loom, the combination with a pin-Wheel and star-wheel and a longitudinally-sliding shaft, of a forked arm engagin a pin-wheel and loosely mounted on said s aft, a collar loose on said shaft, and a spring intermediate said forked arm and said collar.

2. In a loom, the combination with the box pattern-chain, the multiplier patternchain, and intermediate connections, and pin-wheel and star-wheel mechanism, of means for moving the pin-wheel of the box pattern-chain mechanism out of engagement with its star-wheel, to stop the box patternchain at any desired time without stopping the multiplier pattern-chain.

3. In a loom, the combination with the box pattern-chain, the multiplier patternchain, and intermediate connections, and pin wheel and star wheel mechanism of means for moving the pin-wheel of the box pattern-chain mechanism out of engagement with its star-wheel, to stop the box patternchain at any desired time without stopping the multiplier patternchain, said means comprising a longitu dinally-moving shaft, a forked arm engaging the hub of the pin-wheel and loosely mounted on said shaft, a fast and a loose collar on said shaft, an expansible spring confined between said hub and said loose collar, and mechanism for operatin gsaid means.

4:.
