I also combine my mechanism mechanism, 3 is the maiu-pattern-chain cylwith indicating mechanism on the main-patinder, loosely mounted on a stud 4, secured tern-chain cylinder, so that said indicating in the frame 2. Said cylinder or barrel 3 is 50 mechanism will automatically operate my of the ordinary construction, having the grooved or notched heads or ends 3, and carries the main pattern-chain 5, made up of links 6,which connect the bars 7, upon which are mounted rolls 9 and tubes S in the ordinary way. The cylinder is provided with a hand-wheel 10, by means of which said cylinder is turned in either direction, as desired.

The auxiliary or multiplier pattern-chain cylinder 11 is loosely mounted on a stud 12, secured in the frame 2, and carries the aux iliary or multiplier pattern-chain 13, made up of links 6, bars 7, rolls 9, and tubes 8, similar to the main pattern-chain 5. The auxiliarypattern-chain cylinder 11 is provided with a hand-wheel 11 to turn the same, as desired.

On a stud 15, secured in the upper part of the frame 2, on the outside of the stud 4, are pivoted in this instance three shuttle-box indicator- levers 16, 17, and 18, which are operated by the main pattern-chain 5. The outer ends 16, 17, and 18 of said levers are preferably enlarged, as shown, to act as weights, and the inner end of each of said levers is pivoted to the upper end of the connector-rods 19, (see Fig. 3,) leading to the vibrator-levers of the box-motion,(not shown,) which may be of any ordinary construction and operation and is arranged at the lower part of the loom. Upon said stud is also pivoted one end of the weighted indicatorlever 20 and one end of the lock-lever 21, which is provided with a convex portion 21, adapted to extend into the concave portions 22 in the stop-wheel 22, faston the patternchain cylinder 3. (See Fig. 5.)

On the stud 4t and next to the frame 2 is loosely mounted a ratchet-wheel 23, which is secured to the maiu-pattern-chain cylinder 3, and through said ratchet-wheel said mainpattern-chain cylinder is operated, as will be hereinafter described.

On a stud 21, fast in the opposite end of the frame 2 from the stud 15, is pivoted one end of a weighted int'licator-lever 25, which is acted on by the auxiliary or multiplier patteru-ehain 13. On the stud 24: is also pivoted one end of the lock-lever 26, provided with a convex portion 26, adapted to extend into concave portions 27 in the stop-wheel 27, se-

' cured to the auxiliary-pattern-chain cylinder 11. The lower end of the lock-lever 26 is secured to the lower end of the lock-lever 21 by a spring 28, (see Fig. 5,) which acts to move said levers toward each other and hold them in engagement with their respective stopwheels 22 and 27.

A ratchet-heel 29 is mounted loosely on the stud 12 and is secured to the auxiliarypatterirchaiu cylinder 11, and through said ratchet-wheel 2!) said auxiliary-pattern-chain cylinder is operated, as will be hereinafter described.

The mechanism for operating the ratchetwheel 23 to communicate motion to the main pattern-chain 5 and for operating the ratchetwheel 29 to communicate motion to the auxstance of an arm or lever 30, fast on a rockshaft 3]., journaled in the lower part of the frame 2. The arm or lever 30 carries at its upper end two oppositely-extending pawls and 33, pivoted thereon. The pawl 32 is adapted to engage the teeth of the ratchetwheel 23 of the main-pattern-chain cylinder 3, and the pawl 33 is adapted to engage the teeth of the ratchet-wheel 29 of the auxiliarypattern-chain cylinder 11.

On the other end of the rock-shaft 31 is fast the inner end of an arm Motion is comin unicated to said arm 31 and through rockshaft 31 to the arm or lever 30, carrying the pawls 32 and A giveway or look connection intermediate the arm 34: and the driven part of the loom, from which said arm is operated, is provided and means preferably connected with the stop-motion shaft to automatically operate said giveway connection to disconnect the arm 31 and immediately stop the movement of the pattern-surfaces in case the fillin g gives out, and the filling-stop-motion shaft acts to stop the loom. In this instance the outer end of the arm 31 is provided with a pin or screw 35, which is adapted to engage a notch "in the slotted head 36 on the connector-rod 37. (See Fig. 2.) The lower end of said rod 37 is connected with a lever 38, pivoted at 38and carrying a pin 38", which extends into a groove in a cam 39, fast on a driven shaft 10. (See Fig. 1.) A continuous up-and-down motion is communicated to said rod 37 and through the arm 31 to the roelcshaft 31 and the arm 30, carrying the pawls 32 and From the head 36 of the connector-rod 37 a chain or cord 41 leads over a pulley 42, loose on the rock-shaft 31, and over pulleys 43 and 44., mounted on the loom side, (see Fig. 1,) to an arm 45, fast on the filling-stopmotion shaft 46. The rocking of the stopmotion shaft 46 will, through arm and cord 41, draw the head 36 on the rod 37 toward the front of the loom and cause the pin to be disengaged from the notch 36 and be moved into the longitudinal slot 36 in the head 36 to allow said head and the connector-rod 37 to move up and down without moving the arm 34:, so that the pattel'irindieatil'ig mechanisms may be instantly stopped, though the loom may continue to run.

A pawl -17, pivoted on the arm 3-1 and bearing at one end against the inner edge of the head 36 and attached at its other end to one end of a spring 48, acts to push outwardly the head 36 on the rod 37 and hold the pin 35 in the notch 36' to form a giveway or look connection between the connector-rod 37 and the arm 34:.

In order to regulate the operation of the ratchet-wheels and 29 of the main-patterir chain cylinder 3 and the auxiliary-patternchain cylinder 11, respectively, by the pawls and 33, a pawl guard or shield is provided for each pawl to keep the same out of engageiliary pattern-chain 13 consists in this inment with its ratchet-wheel when desired.

The pawl 32, which operates the ratchetwheel 23 of the main-pattern-chain cylinder 3, is provided with a pawl guard or shield 49, pivoted at about its central point on a pin 50 in the frame 2 in such a manner that the end 49, which acts as a guard for the pawl 32, will extend under said pawl. (See Fig. 2.) The other end 49 of said shield 49 is connected by a pin 51 to a boss 52, which extends out from the free end of the weighted indicatorlever 25 of the auxiliary pattern-chain 13. The pawl guard or shield 53 for the pawl 33, which operates the ratchet-wheel 29 f the auxiliary-patern-chain cylinder 11, is pivoted at about its central point on a pin 54 in the frame 2, with its other end 53, which acts as a shield for the pawl 33, adapted to extend under the outer end of said pawl. (See Fig. 2.) The inner end 53" of said pawl-guard 53 is connected by a pin 55 to a boss 56, which extends out from the free end of the weighted indicator-lever 20 of the main pattern-chain 3.

All of the above-described mechanisms are of substantially the same construction and operation as the mechanism shown and described in said Patent No. 544,356.

I will now proceed to describe my supplemental mechanism combined with the mechanisms above described, whereby both the main pattern-chain and the auxiliary patternchain will be automatically stopped and automatically started when desired.

On the stud is pivotally mounted one end of an indicating-lever 57, which, in this instance, is located between the indicatorlever and the lock-lever 21. (See Fig.4.)

The inain-pattern-chain cylinder 3 is provided with indicating-surfaces to act on said lever 57. Said indicating-surfaces may form a separate row of tubes and rolls between the heads or ends 3 of the cylinder 3, or, as in this instance, the indicating surface or roll 58 may be substituted for one of the tubes 8, which extend into the notches or grooves in the ends 3 of the cylinder or barrel 3. (See Fig. 4.) In this way it is not necessary to use a longer barrel or cylinder. The inner end of the indicating-lever 57 is provided with a pin 57, which extends over the top of the arm 30, which forms a stop to limit the downward motion of said lever. (See Fig. 5.)

A link or connector 60 attaches the end of said lever 57 to an arm 61, fast on a shaft 62, mounted in the lower part of the frame 2. (See Figs. 2, 3, and 5.) A second arm 63 is also fast on said shaft 62 and is connected by a link or connector 64 to the lower end of a switchlever 65, pivoted at 66 on the head 36. (See Fig. 2.) The upper end 65 of said lever65 is adapted to extend under the pin or screw 35 in the outer end of the arm 34, as shown in Fig. 3, to cause said arm 34 to move up and down with the head 36 and rod 37 to operate the pattern-surfaces.

A guide plate or shield 66 is secured by the screw 35 to the end of the arm 34, as shown in Fig. 2, and extends over the slotted portion of the head 36 to hold the headin proper position relative to the arm 34. By means of the indicating-surface 58, through the lever 57, link 60, arm 61, shaft 62, arm 63, and connector 64, a positive motion is communicated to the switch-lever 65 to move the upper end 65 thereof out from under the pin 35 in the arm 34, as shown in Fig. 2, to allow the head 36 and rod 37 to move freely up and down without moving the arm 34.

The switch-lever 65 is provided with an outwardly-extending arm 67, the outer end of which is adapted to ride over an inclined surface 68 on the lever 68 and extend into a notch 68 in the inner edge of said lever. A spring 69 acts to hold said arm 67 in engagement wit-h said notch 68 in the lever 68, as shown in Fig. 2, and until said arm 67 is disengaged from said notch the switch-lever 65 will remain in the position shown in Fig. 2, in which position, as before stated, the head 36 and rod 37 are free to move up and down without moving the arm 34. Thus both the main pattern-chain and the auxiliary pattern-chain will remain at rest and the drop-boxes remain stationary while one shuttle is weaving in the body of the fabric.

To release the switch-lever 65 and allow the same to be moved back under the pin 35 to cause the arm 34 to be moved by the head 36 and rod 37 to operate the pattern-chains, I connect the upper end of the lever 68, through a connection 70, passing over a pulley 71, loose on the rock-shaft 31, and overa pulley 72,

mounted on the loom side, (see Fig. 1,) to a lever 73, pivoted at its lower end on a stud 74 in the stand 75 (see Fig. 6) and provided with an arm or lever 76, pivoted thereon to move in a horizontal plane. The free end of the arm or lever 76 is adapted to travel on the'periphery of a disk 77, which is the indicating-disk, and in this instance is made integral with the gear 77, fast on the shaft 78 of the friction take-up roll.

A pinion 79, fast on a driven shaft 80, meshes with the teeth on the gear 77. (See Fig'. 1.) A spring 81 is attached at one end to the projection 82 on the stand 75 and at its other end to lever 73 and acts to hold projection 73 on lower part of said lever in engagement with the heel or projection 76 onthe arm or lever 76 and the free end of the arm or lever 76 011 the periphery of the disk 77. (See Fig. 7.) Projections 73 and 76 are connected by a spring 85.

On the indicating-disk 77 are secured, in this instance by screws 83, indicating devices or switch-cams 84, in this instance two in number. Said indicating devices 84 may be adjusted on the indicating-disk 77 by providing said disk with a series of holes to receive the screws 83.

As the indicating-disk 77 revolves the arm or lever 76 travels on the periphery thereof until it engages the curved plate 84 of the switch-cam 84, which extends over the periphery of the disk, as shown in Fig. 8. The

curved plate 8 t causes the arm 76 to leave the periphery of the disk 77, and the spring 81 acts to move the lever 73 on its pivot 74: and cause the free end of the arm 76 to drop into the notch Si" in the switch-cam 8i against the action of the spring 85. The movement of the lever 73, through connection 70, moves the lever (58 inwardly at its upper end and disengages the arm (57 on the switch-lever from the notch 68 in said lever 68 and allows the spring (59 to act to move the upper end 65 of the switch-lever 65 under the pin in the arm 3i. (See Fig.

From the above description, in connection with the drawings, the operation of my supplemental mechanism, in connection with the operation of the main-pattern-chain and. the auxiliary-pattern-chain mechanisms, will be readily understood by those skilled in the art.

The patternsurfaces are made up to produce the desired pattern in the fabric, and the indicators, which operate the supplemental indicatinglever 57 of my mechanism, are arranged according to the length of the body of the fabric to be woven, and the indicating devices or switch-cams 84: on the indicating-disk 77 are adjusted to correspond.

Supposing the parts to be in the position shown in Fig. 3 and the loom running, as long as a tube 8 on the main pattern-surface comes under the indicator-lever20 said lever will stay down and through the pawl-shield prevent the pawl 33 on the arm 30 from engaging with the ratchet-wheel 29 to turn the auxiliary pattern-chain l3, and a roll 1) on said auxiliary pattern-chain 13, being under the indicator-lever 25, (see Fig. l,) will hold said lever up and keep the end 49 of the pawl'shield 43 down, as shown in Fig. 2, so that the pawl 32 will engage with the ratchet 23 and turn the main pattern-chain 5. The next turn of the main pattern-chain 5, as shown in the drawings, will bring a roll 9 under the indicator-lever 20, (see Fig. 1 which will raise said lever and at the same time lower the end 53 of the pawl-shield 53, connected with said lever 20, so that on the return movement of the arm 30 the pawl will engage with the ratchet-wheel 29 and move the auxiliary pattern-chain 13 to bring a tube 8 under the indicator-lever 25, (see Fig. 4,) which will cause said lever to drop down and at the same time raise the end 49 of the pawl-shield 49, connected with said lever 25, so that on the return movement of the arm 30 the pawl 32 will beheld out of engagement with the ratchet-wheel 23, thus leaving the main pattern-chain 5 at rest as long as the multiplier-chain 13 runs and a tube comes under the indicator-lever 25. As soon as a roll 9 comes under said lever25 the same is raised and the end 49 of the pawlshield 49 dropped, and then the main pattern-chain 5 is operated, as above described, and so the operation continues until in the revolution of the main-pattern-chain cylinder 3 the indicating-surface 58 is brought under the projecting point 57 of the indicatorlever 57. The next revolution of the mainpattern-chain cylinder will raise said indicating-lever 57 and, through link 60, arm 61, shaft 62, arm (53, and connector 64, move the switch-lever 65 into the position shown in Fig. 2. The switch-lever (55 will be held in this position by means of the arm (57, engaging the notch 68 in the lever 08, as above described. The head 30 and rod 37 are now free to move up and down without moving the arm 34, which operates the pawl-carryingarm 30. The body of the fabric is now woven, the main pattern'chain and the auxiliary pattern-chain remaining at rest.

The projecting end 57 of the indicatinglever 57 is so made relative to the indicatingsurface 58 that it will engage said surface to operate the lever 57 in advance of the indicating-surfaces which act on the other levers over the main pattern-chain, and before the surface 58 reaches the top of the cylinder or barrel (as shown in Fig. 5) the pawl-carrying arm 30 will continue to operate by the downward movement of the head 36 and arm 37 to move the cylinder 3 of the main patternsurface sufliciently to carry the indicating surface 58 beyond the projecting end 57 of the indicating-lever 57 to allow said lever to drop at the proper time.

\Vhen the desired length of the body of the fabric is woven, the revolution of the indicating-disk 77, as the friction take-up roll is revolved, will bring the switch-cam 8i into ongagement with the arm 76 and, through spring 81, lever 73, and cord connection 70, the lever (58 will be moved in at its upper end, releasing the switch-lever 65, which is then moved by the spring 09 into the position shown in Fig. 3, with the end 05 extending under the pin 35 in the arm 30. The main pattern-surface and the auxiliary pattern-surface are then again put into operation.

If at any time in the operation of the loom the filling runs out, the giveway or look connection between the arm 3i and the head 36 on the rod 37 operates through the cord or chain 41, attached to the arm 45 on the fillingstop-motion shaft 46, to move in the head 30 and cause the pin to extend into the upper slotted part 36 of the head 36 and allow said head and rod 37 to move up and down without moving the arm 34:. After the filling is replaced the return movement of the fillingstop-motion shaft 46 will slacken the cord 41 and allow the spring-actuated pawl 47 to act to push out the head 36 and bring the pin 35 on the arm 34 into the notch 36' and hold it there to make a connection between said arm 31- and the head 36 on the connector-rod 37.

The advantages of my supplemental mechanism, combined with the main-pattern-chain and the auxiliary-pattern-chain mechanisms, will be readilyappreeiated by those skilled in the art.

I am enabled, automatically, through a supplemental indicating-surface and mechanism operated thereby to automatically stop the operation of the main pattern-chain and the multiplier pattern-chain, and through an indicatingdisk on the take-up-roll shaft or other driven shaft of the loom I am enabled through intervening connections to automaticallyput into operation the main and auxiliary pattern mechanisms.

My supplemental mechanism may be readily combined with looms of ordinary construction of the class referred to, and by means of the adjustable indicating devices or switch-cams on the indicating-disk 77 I can adjust the same according to the length of the body of the fabric desired to be woven without changing the disk. By changing the gears 7 7 and 79 I can vary the, speed of the indicating-disk 77 to make it revolve faster or slower, as desired.

It will be understood that the details of construction of my'supplemental mechanism may be Varied somewhat, if desired.

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

1. In a loom provided with main-patternchain and auxiliary-pattern-chain mechanisms, the combination with said mechanisms, of a supplemental mechanism, consisting of a supplemental indicating-lever, a supplemental indicating-surface, to engage said le- Verin advance oft-he engagement of the other indicating-surfaces on the main-patternchain cylinder With their respective indicatin g-levers, and connections from said supplemental indicating-lever to automatically disengage the mechanism Which operates the vmain and auxiliary pattern-chain cylinders,
