Application filed September 16,1905. Serial No. 278.699.

'which the following'description, in connection with the accompanying drawings, is a specification, like characterson the drawings representing like parts.

This invention relates more particularly to looms provided with means to automatically replenish the running filling and having filling-detection mechanism to detect filling failure on each pick.

In the class of looms technically termed feeler-looms filling replenishment is effected prior to complete exhaustion of the supply of filling in the active shuttle to prevent the possibility of thin places being made in the cloth.

Another class of looms is provided with double filling-detecting devices to'pdetect filling failure on each pick and with means to effect arrest of the take-up on each detection.

In United States patent to Stimpson, No.

763,441, dated June 28, 1904, a loom is shown and described provided with feeler mechanism to effect filling re lenishment prior to complete'exhaustion o the fillingsupply in the active shuttle, two filling-detectors todetect filling failure on alternate picks and adapted to arrest take-up when filling failure is detected by either detector, and stopping meansfor the loom operated by or through detecting action of either detector.

f United States Patent'No. 789,291, granted to me May 9, 1905, has for its subject-matter a double-detection automatic filling-replenishing loom wherein filling replenishment is effected or controlled directly by one of the detectors and indirectly when filling failure (breakage or running out of the filling) is detected' by the other detector, both detectors arrestingtake-up upon detection of filling failure b y either detector.

My present invention has for its main object the production of a loom embodying the features of both of the mechanisms shown in the patents referred to-that is, an automatic fillingreplenishing loom provided with-a feeler and two filling-detectors, but so arranged that by achange in the position,

and consequent operation, of a controlling,

or governing member the loom may be operated in a variety of ways, according to the character of the work to be performed. These various modes of operation may be, for convenience, classified as follows:

A. Operating as an ordinary feeler-loom, Y

nothing more than retaining the feeler mechanism inoperative.

O. yOperating with the feeler mechanism in action, but with the two filling-detectors acting to sto the loom upon breakage of fill- .ing or if the lling runs out immediately upon the action of the feeler. The conversion of the loom to operate as in case C is effected by a change in the controlling or governing member, as will be explained. l

` D. By rendering the feeler inoperative when the loom is set to operate as in case C the loom will operate as a common double- ,fork loom, arresting take-up and stopping the loom vwhen the filling runs out or breaks. Thus the one loom instrumentality is given a very wide range of operation to suit the various conditionsarising in actual practice, so that it has the capacity of four different looms, each corresponding to one of the fourv cases set forth.

I have .shown the filling-eXhaustion-indieating mechanism herein substantially the Asame as that lshown and described in United States Patent No. 789,472, granted May 9, 1905, to me and another; but-other suitable TOO filling-exhaustion-indicating mechanism may I p.

be employed without departing from my present invention. l

The double-detector ldevices herein illustrated are substantially such as form the subject-matter of my PatentNo, 789,291,

hereinbefore referred to, as such devices are particularly well adapted for use herein.

The various novel features of construction, arrangement and operation will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top plan view, centrally broken out, of an automatic filling-replenishing loom embodying one form of my present invention set for operation in accordance with the provisions of case A, above referred to. Fig. 2 is a front elevation, enlarged and also broken out, of the connections between the two filling-detectors and the controlling rock-shaft for the iilling-ieplenishi.ng mechanism with the parts set as in Fig. 1. Fig. 3 is an enlarged transverse sectional view on the line 3 3, Fig. 1, looking toward the right. Fig. 4 is a similar view of the parts shown at the upper portion of Fig. 3, but omitting certain details shown therein by dotted lines. Fig. 5 is a detail in front elevation of the parts shown at the left, Fig. 2, but with the controlling or governing member changed in position to thereby convert the loom from operation under cases A and B to that under cases G or D. Fig. 6 is a view similar to Fig 4, but showing the changed position of the controlling member corresponding to that shown in Fig. 5. Fig. 7 is a like view, but omitting the latch and the controlling member in order to show clearly certain details of construction obscured in Fig. 6. Fig. S is a perspective view of the latch detached, viewed fromits inner side. Fig. 9 is a perspective view of the controlling or governing member turned as it would be for either cases C or D. Fig. 10 is a side elevation of the controlling member reversedas it appears in Figs. 3 and 4. Fig. 11 is a perspective view of the upper end ofthe support on which the controlling member is pivotally mounted; and Fig. 12 is an outline view, in side elevation, of the t'wo cams which govern thefweft-hammers or followers which coperate with the two filling{ detecting devices.

Referring to Fig. 1, the lay A3, provided with suitable shuttle-boxes B BX, the automatically-self-threading shuttle SX, the filling-replenishing mechanism at the righthand side of the loom and including the transferrer F and illing-feeder F, (partly shown,) the controlling rock-shaft CZ', which governs the operation of the replenishing mechanism, the shipper S, its notched holding-plate N, and a releasing device er knockoff lever NX for the shipper. may be and are all of well-known construction and operate in usual manner, the inner end of lever NX having an enlargement or shelf n, as in my Patent No. 789,291.

The two filling-detectors are located at the l replenishing and shipping sides of the loom,

respectively, and the fermer detector, termed the auxiliary filling-detector, includes a filling-fork g and its slide gX, longitudinally movable in a fixed guide g2, the fork-tail g2 being engaged by the hook wX of an actuator or weft-hammer WX when the fork is not tilted to thereby move the slide outward. Such movement of the slide swings out the upper end of arm d5, fast on the rock-shaft l, turning the latter in the direction of arrow 250, Fig. 3, a spring SX moving the slide qX inward, as will be manifest, and, as will appear hereinafter, such turning of the rock-shaft is adapted to arrest tale-up.

The cam for imparting the throw to wefthammer WX is of novel shape in order to se,- cure a certain operation, as will be described. hereinafter.

The main 'filling-detecter at the shipping side of the loom includes the forkf, having a tail f2() and mounted on a slide fX, moved outward in a guidef by the weft-h amm er W when its hook engages the fork-tail, the outward movement of the slide engaging the head d50 of an arm d, loosely mounted on the rock-shaft (Z, said arm having secured to it a depending and rearwardly-projecting extension (Z2, (see Fig. 3,) adapted when elevated to cause the. arrest of the take-up mechanism (not shown) in. substantially the manner described in my Patent No. 7S9,291that is, a lug d3 on the extension may en gage the p awlcarrier pX and move the same to disengage the pawl from the ratchet in take-up mechanism of the character shown in United States Patent No. 643,284.

As best shown in Fig. 11, the head d5" has an upturned ear el at its outer end provided on its outer face with a lateral lug d, having a hole d5 for a retaining device, and the front of the head is shaped to present a transverse lip d5* for a purpose to be described. A spring s moves the main slide f X inward. The hook 2 fulcrumed on the weft-hammer W, having a shoulder 4 to cooperate with the fork-tail, and the guard 5 are shown as in my Patent No. 789,291, the slide having elevated sides connected by a stop-bar 9, with notches in the forward extensions of the sides, as in said patent, the prolongation 15 of the slide. cooperating with the spring s. So, too, a dog 20, Figs. 1, 3, and 7, on a carrier comprising a body 17, having detents 19 to cooperate with the notches in the sides of the main slide, and the hooked front end 27 of the earrier are all substantially as in said patent, as are the other features of the carrier, the purposes and operation thereof being fully described in the said patent. time and under certain circumstances the dog 2O will engage the shelf rt of the knockofl lever i X and will turn the same to release the shipper, as described in my said patent.

The filling-exhaustion-indieating mechanism can now be referred to brie'lly, and in order to avoid confusion the reference-num- IOO At the propel' 789,472 and operating as therein provided.

The tilting transmitter 34 35X, fulcrumed at 33X and having its outer end bent at 37X vand provided with a cam-slot (not shown) through which is extended the controller X, the end of the latter lying in the operative path of movement of the actuator 26X, are

also as in said patent, the free end of thel transmitter-arm 34 extending under the rear end of the latch 613x, fulcrumed at its out, end on an upturned arm d, fast on the rockshaft d. So long as there is more than a pre- 'determined amount of filling in thel running shuttle the feeler, which intermittingly passes through usual` openings in the side wall of the shuttle and the front wall of the left-hand shuttle-box B, Fig. 1, will act to render the actuator 26X inoperative, and the trans lnitter will remain uiescent. When, however, predetermine filling exhaustion is reached7 the actuator'l becomes operative, and the controller 40X is engaged and movedto tilt the'transmitter, lifting the free end of its arm 34 and elevating the rearend of the latch d3X into position to Lbe engagedby a head wX on the weft-hammer W. On the forward swing of the latter the latch d3X is pushed forward, acting through arm 12X to` rock the controlling rock-shaft d in the direction of arrow 250, Fig. 3, and filling replenishrnent is eHlected when the shuttle reaches lthe replenishing shuttle-box BX', Fig. 1. A lug 4X on the latch projects under the adjacent side of the uide f2 andv prevents any undue uplifting of the latch.-

Referring to Fig. 12, the cams C and C for operating theweft-hammers W and WX, respectively, are shown in .their proper relative position, cam C'being of usual contour; but the cam C has an increased rise at c and a shortl dwell @2f succeeding it, the rotation of the `cams being indicated by theA arrow. When the rise c acts on the weft-hammer WX, it gives it a-rapid forward movement, followed by a rest or dwell, and this is made effective at certain times for al purpose to be referred' to.

, From the foregoing description it will be evident that the rocking of the controllingshaft d can be readily effected by or through the latch d3 when the filling-exhaustion-indicating mechanism detects predetermined exhaustion of filling in the running shuttle to thereby cause filling replenishment, and it will be evident that outward Imovement of the auxiliary forkeslide gX will through arm# d5 rock the controlling-shaft 5 but as the arm d is loose on the latter it remains to be described how such operation of the fork-slide gx. can eHect arrest of take-up and filling replenishment indirectly through the main fillingdetector f. It is also necessary ,to describe the manner in which the said main filling-detector can directly effect filling replenishment, such explanations also involving the construction and operation of the controlling member or governingdeviceby ork through which the operation of the loom is varied. f

Referring to Figs. 9 and 10, the controlling member or controller,H as it may be termed,

consists of an elongated body 40, having a triangular frontend 41 provided with a hole 42 to loosely receive the lug 52 on the arm d,

two notches 44 being formed in said end, the rear end of the body having notches 45 46.

On the edge of the bodynearest to which the notch'45 is located is a shoulder 47 vand on the opposite edge another shoulder 48, the body being enlarged at 49 to provide for such shoulders, and it will be noted that the shoulder 47 is considerably nearer the enlarged end 41 of the controller; Said end 41 is provided on one face with a lateral lug A50, having one of its faces cam-shaped transversely, as at 51, the base of the lug being enlarged, as at 52. This controller is pivotally mounted on the lug (152 of the arm d, and it is reversible thereon to thereby determine the manner in which certain portions of the loom are to operate.

roo`

When the loom is to be run in accordancev i with cases A and B, hereinbefore explained, the controller is so mounted that its lug 50 will extend to the left, Figs. 1 and 2, under the latch LPX, with the shoulder 48 downturned, the controller being located between 'slipped into the hole 53 of the fulcrum-lug (152, retaining the controller thereon, and the free end of the retainer is snapped into the upper one of the notches 44 to normally de*- press the rear end of the controller in the position shown in Fig. 4, the shoulder 48 then resting on a part of the stand or guidefz.

It will be understood that upon predetermined exhaustion of filling the latch d3 l will be raised and then moved outward to rockY the controlling rock-shaft d', and thereby eect filling replenishment, the lifting of the latch raising the tooth 15X above the notch 45 of the controller, so that no engagement takes place and there will be no arrest of take-up.` Suppose, however, that prior to predetermined exhaustion the filling breaks and deshaft d far enough to bring the latch-tooth l tection thereof is first made by the main fork l f. Then the slide f thereof will be moved I outward by or through its cooperating weft-hammer W in usual manner, and the slide will engage the head d50 of the arm d, swinging said arm outward and arresting take-up through the extension d2, At the same time the arm d moves the controller outward and the lug 5() on said controller will engage the bend 54 at the front end of the latch, moving the latter outward and rocking the shaft d in the direction of arrow 250, Fig. 3, to thereby effect filling replenishment. Such replenishment is thus effected directly by or through the main fillingdetector, as will be obvious. Now let it be supposed that for some reason the said main detector does not detect filling breakage, but that as the shuttle is thrown to box B such failure is detected by the auxiliary detector g, and its slide g is moved outward by the weft-hammer WX. This slide movement opcrates, through arm d5, to rock the controlling- 5X into engagement with the controllernotch 45, and the controller will be moved forward, thereby swinging the loose arm d and arresting take-up; but on such swing of the arm the lip di on its head will engage the hooked end 27 of the carrier 17 and move the latter forward to impart what is termed the initial movement ofthe main slide fx in my Patent No. 789,291, rendering the main fork f irresponsive on the next pick to the presence of filling, and consequently the operation of the replenishing mechanism will be effected when the complete outward movement of the main slide is accomplished by its actuator or weft-hammer TV, all as rovided for in said patent. Thus the auxiliary detector operates upon detection of filling failure to causel filling replenishment indirectly throughlthe main detector, substantially as in my prior patent just referred to.

By reference to Figs. 3 and 4 it will be seen that while the shelf n of the knock-off lever is in the path of the shoulder 48 of the controller the shoulder is so far back that forward movement of said controller, such as hereinbefore described, is insufficientto bring the shoulder into cooperative engagement with the shelf. When the loom is operating as in case A, it may sometimes happen that when the feeler mechanism has operated to effect filling replenishment the filling will break or it will run out on the flight of the shuttle to the replenishing side of the loom, (such running out being due to delayed action of the feeler,) and thereupon two successive replenishments will be eHeeted, the first due to the feeler mechanism and the second through the filling-detection instrumentality. This is of course wholly unnecessary, for it involves two operations of the replenishing mechanism when only one is required, and as a fresh supply of filling has been provided by the first operation there is useless denud ation of the replenishing-magazine by the second filling replenishment. T have provided means to prevent such an occurrence, as I will new explain. Upon such failure of the filling the fork g detects, and its tail is engaged by the hook of weft-hammer WX as the latter bcgins its forward stroke, the rise c giving a quick movement thereto at the start, while the hammer XV is forward and just going back, the lifting of the latch d: having permitted the tooth (15X to ride forward on the top of the controller enlargement 49. 'lhe dwell c2 now operates to hold the rock-shaft d stationary for a moment, retaining the latch from rearward movement as its wefthammer 7 moves back, while the tooth dsx still rests on the top of said enlargement 49, and then as the cam C passes the dwell portion the usual forward movement of the latch d3 is completed; but as the tooth has had no opportunity to drop behind the controller and into engagement with its notch 45 there is no forward movement of the controller, and hence no filling replenishment nor arrest of take-up. `Were it not for such holding forward of the latch the tooth thereof would drop behind the rear end of the controller and the rocking of the shaft d through movement of the slide (/X would move latch and controller forward to cause a filling replenishment by or through the main filling-detector. lf the loom is to operate as in case B, with the iilling-exhaustion-indicating mechanism out of action but with filling replenishment effected automatieally by or through detection of filling failure by either filling-detector, the said mechanism is thrown out of action and so maintained. This is conveniently effected by pushing forward the feeler until a hole 10() (see dotted lines, Fig. 1) in its shank 14X is exposed at the front end of the stand. 9 and a Cotter-pin or other suitable pin is dropped into the hole, maintaining the feeler device retracted and inoperative.

Of course there can be no control of the latch (13X by the feeler so long as it is held inactive,

and consequently the loom will operate to all intents and purposes as iu my Patent N o. 789,291, the filling replenishment being effected through the double-detecting devices.

To change from case B back to case A, all that is necessary is to throw into operation the filling-exhaustion-indicating mechanism, which in the construction thereof shown in Fig. 1 is attained by releasing the 'feelershank 14X.

It will be understood that inu both ease i and case B there is no objection to the presence of an occasional pick in which the filling is more or less incomplete, such picks occurring when a break in the filling occurs or when the filling breaks or runs out immelof rif

diately after the action of the feeler, as has been explained. 'There are certain classes of goods, however', which must not contain such incomplete picks of filling, and when- -50 extending back of the bend 54 in the latch dax; but to change to case C the operative removes the spring-retainer 53, slips the controller 40 from the fulcrum-lug dm, and reverses the controller, replacing it on the fulcrum-lug with the lug 50 projecting to the right (see Fig. in front of the head d5* on the arm d, the extremity of the lug lying beneath the hook 27 of the carrier 17, as shown in Figs. 6 and 7. The retainer 53 is then replaced in the hole d53 of the fulcrum-lug and its free end snapped into the then uppermost one of the notches 44 of the controller. Now by reference to Fig. ,6 it will be seen that the shoulder 47 of the controller is quite near the-shelf n of the knock-off leverN and also that the tooth d5x of the latch dsx is vadapted to coperate with the controllernotch 46 unless the latch is lifted prior to forward movement thereof.

When the running filling is exhausted to a predetermined point, the lling-exhaustionindicating mechanism operates, the transmitter-arm 34x lifting the latch into engagement with the head 'w'x of the weft-hammer W, and on the forward movement of the latch the controlling rock-shaft d is rocked and filling replenishment is effected. If the filling fails, however, and it is detected by the main detector f, the slide f x thereof will be moved "outward, acting upon the head d50 to rock the arm d and arrest-talre-up, and at the same time the controller 40 is moved outward, bringing the shoulder 47 against the shelf n, thereby rocking the releasing-lever Nx and throwing the shipper out of its holding-notch to stop the loom. Ifiilling failure is detected by the auxiliary detector g, its slide is moved outward, and through-the arm d5 the rock-shaft d is turned, such turning acting through the arm dzx to move forward the latch dax, and as its tooth d5x is then in operative position it engages the notch 46 and moves the controller forward, the shoulder 47 operating as before to effect shipper release. Such forward movement of` the -controller acts through the arm d to arrest 'take-'u as previously explained- When the contro ler is moved forward, the cam-face 51 on its lug 50 acts upon the hook 27, lifting it above and out of engagement with the lip d54 on the head d5", and thereby obviating any movement of the carrier 17 on the main slide fx.

Referring to Figs. 9 and 10, it will be seen that there are two longitudinal ledges 61 62 on opposite sides ofthe controller 40 andadjacent its upper and lower edges, respec tively, one or the other ledge projecting bef neath the latch dsx to prevent any accidental jumping up of the rear end of the controller. Suppose that the feeler has operated to effect filling replenishment (the loom operating under the provisions of case C) and the filling breaks or runs out on the shot of the shuttle to the replenishing side of the loom. If no provision be made to guard against this occurrence, a mispick will bev made, as the loom would continue to run after replenishment and a pick would be made with only a partial filling laid therein. As the latch d3x has been lifted and moved forwardV through the feeler action, its tooth dix is above the controller 40, and upon filling failure the auxiliary detector g detects the failure, the tail g20 being caught by the hook wx of wefthammer Wx while the weft-hammer W is forward and just about to go back. The quick movement given by the rise c of the cam C acts, through the armsd5 and dzx and the shaft d to move the latch dsx forward a corresponding distance, while the dwell c2 holds the latch stationary as the weft-hammer W moves back out of cooperative engagement with the rear end of the latch, so that when the controller-notch 46.- Now the earn C takes up again the forward movement of the weft-hammer Wx and the rock-shaft d y is turned further to move the latch forward far enough to act lthrough the controller to re'- lease the shipper by or through engagement of the shoulder 47 with the shelf n of the knock-off lever Nx. The notch 46issomewhat nearer the front'of the controller than the notch 45, so that the peculiar action of the cam C is helped or assisted by the position of the notches in the one instance to operate the controller through the latchand ink the case previously described to prevent operation of the controller by the latch. The principal function of the rise c is to compenparts during the complete revolution of cam IOO the latch drops its tooth dx will drop behind III:

C/ will not be changed. There remains to be considered only the operation of the loom as in case D, and this is effected (when the loom is set for', operation as in case C) merely by withholding the lling-exhaustionindicating mechanism from operation by retracting the feeler, as in case B. Now the ,loom will run simply as a double-fork loom,

rigo

arresting take-up and stopping the loom on either breakage or running out of the filling.

In order to change the loom to operate in the several ways hereinbefore described, it will be manifest that very little manipulation is required, the change from cases A and B to C and D being effected by a reversal of the controllerthat is, in cases A and B the controller is lin one position, and the difference between such cases is due to the action or inaction of the filling-exhaustion-indicating mechanism, while in cases C and D the controller is in reversed position, and the difference in operation between cases C and D is due to action or inaction of the said indicating mechanism. With respect to the latter it should be stated that when the same is withheld from operation (see cases B and D) the transmitter is in normal position with its arm 34X lowered.

My invention is not restricted to specific yd tails of construction such as herein shown ..ai 1ddescribed, as the same may be varied or ,modified by those skilled in the art without departing from the spirit and scope of my invention.

In a loom provided with filling-replenishing mechanism, in combination, means, including a latch, to effect the operation of `said mechanism prior to complete exhaustion of the running filling, av vibrating weft-ham mer to at times coperate with and operate` the latch, two filling-detectors each having a slide and adapted to detect filling failure on alternate picks and also adapted to arrest the operation of a take-up instrumentality upon detecting action of either detector, means to effect operation of the replenishing mechanism upon the detection of filling failure by either IOO IIO

detector, a shipper, a releasing device therefor, a reversible controller having a notched inner end and a shoulder, a tooth on the latch, dctection of filling failure acting, when the controller is in one position, to efl'ect filling replenishment through such controller, reversal of the controller causing its shoulder to operate the shipper-releasing device upon detection of filling failure, and means, operating upon filling failure immediately following replenishment, to hold the latch forward when released by its cooperating weft-hainmer, to thereby prevent engagement of the latch-tooth with the notched end of the controller, thus preventing a second filling replenishment through the detectors.

16. In a loom provided with filling-replenishing mechanism, in combination, means, including a latch, to cause the operation of said mechanism when substantial exhaustion of the ruiming filling is indicated, two filling-detectors to detect filling failure on alternate picks, a weft-liaminer to cooperate with each detector, a stopping instrumentality for the loom, means, including a manually-reversible controller having a shoulder and a lateral lug, to effect filling replenishment or loom stoppage upon detection of filling failure, the controller, when in one position, actingthrough its lug upon the latch to operate the replenishing mechanism, and when in reversed position acting through its shoulder to operate the stopping instrumentality, and weft-hainmer-operating cams one of which operates, when the filling-eXliaustion-indicating means is operative and the controller is in its first position, to prevent a second filling replenishment uponfilling failure following filling-exhaustion indication, said cani acting, when the controller is reversed and the filling-detectors are operativ to stop the loom, to effect coperation of he latch and controller and cause loom stoppage upon detection of filling failure immediately following the operation of the eXh austion-indicating means, to thereby prevent a mispiek. 4

17. In a loom, in combination, filling-replenishing mechanism, two filling-detectors to detect filling failure on alternate picks and adapted to arrest the operation of a take-up instrumentality by detecting action of either detector, a stopping instrumentality for the loom, a controller manually changeable as to its position and when in one position causing filling replenishment, and when in its other position causing loom stoppage, upon detection of filling failure, whereby the loom will operate to replenish the running filling Or will be stopped upon failure of such filling, fillingexhaustion-indicating means, including a feeler, to normally effect the operation of the replenishing mechanism prior to complete exhaustion of the ruiming filling when the controller is in either position, retrzuztion of the feeler rendering said indicating means inoperative, and means to prevent a double action of the replenishing mechanism when said indicating means is operative and filling fails immediately after exhaustion indication, with the controller in its first position, said means also acting to prevent a mispick and insuring loom stoppage upon similar filling failure when the controller is in its reversed position.

1S. in a loom, in combination, means to cause filling replenishment prior to complete exhaustion of the ruiming filling and ad aptcd to be maintained inoperative at will, separate means adapted to either cause filling replenishment or to stop the loom upon failure of filling, and a controller to determine by its position whether said second-named means` shall cause filling replenishment or loom stoppage, irrespective of the operation or non-operation of the first-nanied means..

19. In a loom, in combination, means to replenish filling prior to complete exhaustion of the ruiming filling, separate means adapted to either replenish filling oi' to stop the loom upon failure of filling and adapted to arrest the operation of a take-up instrumentality, and a controller to determine by its position whether the secOiid-iiaincd means shall cause filling replenishment or loom stoppage.

20. In a loom provided with filling-replenishing mechanism, and means to cause the operation thereof prior to complete exhaustion of the ruiming filling, in combination, means to detect filling failure, a stopping i11- struinentality for the loom, and means to at will cause the operation of either the replenisliing mechanism or of the stopping instrumentality on detection of filling failure.

2l. In a loom, provided with filling-replenishing mechanism, and. means to cause the Operation thereof, prior to complete exhaustion of the running filling, in combination, means to detect filling failure on every pick, a stopping instrumentality for thc loom, and means to at will cause the operation of either the replenisliing mechanism Or of the stopping instrumentality on detection of filling failure.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JONAS NORTHROP.
