Serial No. 158,917- (No model.)
To all whom it may concern.-
Be it known that 1, DAVID ROBINSON, a subject of the King of Great Britain, and a resident of Pawtucket, county of Providence State of Rhode Island, have invented an 1m provement in Multiple Harness Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
In a multiple-harness loom-that is, aloom, 1
in which the shedding cycle comprises three or more pioks-if the filling fails and the loom turns over a few picks without laying filling in the shed it is necessary for the weaver to turn the loom either backward or forward until the pick of the cycle is found in which the last filling was laid in order to match the pick. The new filling or the continued laying of filling is'then started from the point where the filling was previously laid and terminated. This of course is important only when a'matched pick and an unbroken pattern in the weave is required, and it will be manifest that the greater the number of harnesses or,what is equivalent, the greater the number of picks in the shedding cycle, the more will the loom have to be turned over when it is necessary to find the pick in which the filling In a feeler-loom wherein fresh filling is provided automatically upon substantial exhaustion of the running filling shuttle-the loom is very apt to turn over a few picks before its stoppage due to filling failure. Such filling failure may be breakage of the filling or a failure of the filling to When it is desired to find or match the pick in a multiple-harness loom, the usual practice is to take the shuttle out of the shuttle-boX and turn the loom over by hand until thedesired pick is found, care being taken by the weaver to prevent the dagger of the protector mechanism from striking the frog. If the loom be also provided with filling-replenishing mechanism and a controlling-filling-feeler, care must also be taken to prevent the feeler from causing the operation of the filling-replenishing mechanism, because as 1 tion. 1 shuttle in either box it is necessary to arrest I the taking up of the cloth while no filling is i being laid in the shed, andmeans for accomj plishing this result are herein provided.
'5. 6., the filling which is being laid by the there is no shuttle in use the feeler will act as it would upon substantial exhaustion of I the running filling.
The present invention has forits object the production of means for greatly facilitating I the finding or matching of a pick in a multipie-harness loom, and as will appear hereinafter it is equally adapted to a non-rcplen 1 ishing loom or a replenishing feeler-loom, ;wherein the shedding cycle comprises three or more picks and it is requisite to match the pick. In accordance therewith the invention comprehends means manually controlled and movable into position to prevent or arrest the operation of the protector mechanism and also to prevent the operation of replenishing mechanism in a loom so equipped. The shut- 1 tle is then removed, and the weaver can run 5 the loom without hindrance for as many picks as may be necessary by holding on the I shipper, and when the desired pick is found the loom is stopped and the shuttle inserted. fInsertion of the shuttle releases the parts 1 from the control of said manually-controlled means, and the latter is returned automatically to normal position, leaving the loom in condition to be started for continued opera- By thus running the. loom with no The various novel features of the invention :will be set forth hereinafter in the specification describing one practical embodiment thereof, and such novel features will be particularly pointed out in the following claims. be properly laid after filling replenishment.
? ing one practical embodiment of the invention, the loom being shown as equipped with automatic filling replenishing mechanism land a controlling fiiling-feeler. .plan view of the left-hand portion of the loom, showing the feeler mechanism and the I means in inoperative position for preventing the operationof the protector and filling-re- I plenishing mechanisms. 1 view omitting some of the parts illustrated in Fig. 2, but showing the manually con- Fig. 2 is a Fig. 3 is a similar trolled means in operative position to permit the loom to be run without the shuttle. Fig. 4 is a detached plan view of the manuallycontrolled means detached; and Fig. 5 is an enlarged transverse sectional detail on the line 5 5, Fig. 2, looking toward the right.
Referring to the drawings, the breast-beam A lay A equipped with usual shuttleboxes, one of which is indicated at B, Figs. 2 and 3, the protector mechanism, including a springcontrolled rock-shaft P, mounted on the lay, its upturned binder-fingers P, one for each binder P the dagger P to at times cooperate with the frog P Fig. 1, the shipper N, its' notched holding plate N and the knock-off lever 19 Fig. 1, to release the shipper and stop the loom by or through engagement of the dagger with the frog may be and are all of well-known or usual construction and operate in a manner familiar to those skilledin the art.
The loom is shown as equipped with fillingreplenishing mechanism, including a filling feeder or hopper at F, Fig. 1, a transferrerf, and a controlling rock-shaft d, all of which may be substantially as in United States PatentNo. 677,607, dated July 2, 1901. So, too, the feeler-arm f f fulcrumed at a, and provided with a wear-plate 90 and the feeler proper, f to intermittingly pass through slots in the front Wall of the shuttle-box B and shuttle to periodically engage and be moved by the filling in the shuttle until such filling is substantially exhausted, are substantially as shown in said patent.
The filling-fork 'm its slide m, the WefthammerW, having the usual hook to engage the tail of the fork and move the slide out- .ward upon detection of failure of filling, (as
its breakage or a failure of the shuttle to thread upon filling replenishment) and to operate the knock-off lever n M, Fig. 2, to release the shipper, are all of usual construction.
An upturned arm d fast on the rock-shaft d, has pivotally connected with it the outer end of a latch d, the rear end d of the latch being adapted to at times be engaged by a hunter w (see Fig. 5) on an upturned head to on the weft-hammer at one side of the guide for the Weft-fork slide m, as in United States Patent No. 720,209. A projection'w on the head to cooperates intermittingly with a cam-face d on the under edge of the latch, Fig. 5,, and the plate 90 is moved beneath an overhanging shoulder cl on the latch by a spring 70, thus maintaining the latch end d in the path of the bunter tU Filling-induced movement of the feelerf withdraws the plate and the latch end drops below the hunter path as the weft-hammer swings forward, and on its backward swing the projection to engages the cam-face d and lifts the latch to permit the plate 90 to again pass under the shoulder (1 all as in Patent No. 720,209.
In Fig. 1 a portion of a multiple-harness shedding mechanism is shown, comprising in the present instance ten leaves or harnessframes 1, 2, 3, to 10, suspended by overhead connections from the head or top motion 11 of any suitable construction, the'particular form of dobby-head or top motion forming no part ofthe invention. The shedding mechanism is supposed to operate througha cycle of a certain number of picksten as herein shownaud it is supposed that the pattern or weave is such that it is incumbent upon the weaver to match the pick upon filling failure. In order that the shuttle may be removed and the loom run by power without hindrance to find the desired pick, the
loom is provided with means to prevent operation of the protector mechanism in the first place and to prevent the filling-replenishing mechanism from operating in the second place. To this end a plate E, having longitudinal slots 6*, is slidably mounted on the ,top or cover plate b of the shuttle-box B, Figs. 2 and 3, and held in place thereon by headed studs 6 and washers 12, a spring 5 secured to the outer end of the plate E and to the cover-plate, normally retaining said plate 7 which at its rear end terminates in' a shoulder e (clearlyshown in Figs. 2 and 4,) and the adjustable contact-stud p on the binder-finger P is shown as provided with an upturned extension 29 in the path of movement of the cam-face e when the latter is moved inward. A projection or handpiece e on the plate E facilitates its movement by the operator.
Supposing the loom to have been stopped, as by detection of filling failure, the weaver moves the slide E inward into operative position,(shown in Fig. 3,)such movemeutbring ing the cam-face e into engagement with the binderfinger extension 19 and pressing it back until it snaps behind the shoulder e and then the plate is held in operative position. At the same time the part c of the plate adjacent the shoulder holds the extension back, with the binderfinger pressed back far enough to raise the point of the dagger P well above the frog, so that the loom cannot bang off. The operator now removes the shuttle and moves the shipper to running position and runs the loom carefully, but without any danger of hanging off, until the desired pick is reached, sometimes running the loom through practically a complete shedding cycle. The proper pick having been reached, the loom is stopped and the shuttle is placed in the proper shuttle-box,
its engagement with either binder pushing the latter out far enough to throw the extension 19 back beyondthe shoulder 6 Thereupon the plate E is released, and the contraction of the spring s restores it to normal inoperative position, Fig. 2, and the loom can be started up in regular operation.
With feeler controlled replenishing mechanism it is also necessary, when running the loom without the shuttle, to prevent the operation of the replenishing mechanism, and for this purpose the plate E, near its outer end, is provided with an |shaped extension E, which crosses the shuttle-box and overhangs the front wall 19 thereof, Figs. 1, 2, and 3. From the extremity of the extension projects a hunter 6 shown as slightly down- Lurned at its front edge, at e, the normal position of plate E causing the hunter to remain clear of the feeler f or any of its connected parts. When, however, the plate is moved inward to operative position, Fig. 3, as described, the hunter is brought opposite the outer end of the feeler-arm f and when the lay heats up the downturned end 6 of the hunter engages the feeler-arm and moves it forward, withdrawing the plate 90 from the latch-shoulder 01*, just as is the case with filling-induced movement of the feeler. 0onsequently the loom may be run without the shuttle and the filling-replenishing mechan-,
ism cannot be operated at such time. As no filling is laid when the loom is run without the shuttle, the take-up must be prevented from operating to take up the cloth, or thin places in the latter would be produced. Such control of the take-up can be effected in various ways, and one practical Way is herein shown, it being remembered that the Wefthamrner operates on alternate picks. The only portion of the take-u p mechanism shown is a part of the take-up ratchet a its actuating-pawl a detent-pawl 6 and let-back pawl f substantially as in United States Patent No. 643,284, dated February 13,1900.
An upturned arm d loosely mounted on the rock-shaft d, is swung out by every forward movement of the fork-slide m, and said arm 01 has a depending extension L1 to engage a pin a on the pawl-carrier a and disengage the take-up pawl and ratchet when the forkslide is moved outward. As in the patent just referred to, when the pawl a 'is disengaged from the ratchetot the pawl e is lifted and the pawl f will permit the ratchet to let back as many teeth as may be necessary or advisable. If the pawl takes up one tooth of .the ratchet on each beat of the lay, then let-back would be for two teeth, owing to the operation of the fork-slide on alternate beats. If the loom be equipped with two forks, then take-up can be arrested on each pick in which the filling is arrested, as provided for in United States Patent No. 727,014, for example.
From the foregoing description it will be manifest that whenthe weaver is running the loom without the shuttle to find or match a pick he must manually retain the shipper in running position, for unless so retained the fork-slide would release it and stop the loom. He is thus obliged to watch the oper ation of the loom closely and carefully and to stop the loom when the required pick is found.
made by those skilled in the art in the construction and details of arrangement of the various parts herein shown and described without departing from the spirit and scope of the invention, one practical embodiment thereof being illustrated and explained herein.

12. In a loom, shed-forming mechanism adapted to operate in a recurringcycle of three or more picks, a shuttle to lay the filling, means operative automatically by or through fillingfailure to stop the loom, protector mechanism, mechanism to replenish the shuttle with filling automatically upon substantial exhaustion of the filling therein, a lay, and means mounted thereon and movable manually into position to prevent the operation of the protector and filling-replenishing mechanisms, whereby upon removal of the shuttle after automatic stoppage of the loom the latter may be run to complete a shedding cycle and find the pick in which filling failure occurred.
13. In a loom, shed-forming mechanism A adapted to operate in a recurring cycle of three or m ore picks, a shuttle to lay the filling, means operative automatically by or through filling failure to stop the loom, protector mechanism, including a shuttle binder and a binder-finger, mechanism to replenish the shuttle with filling automatically upon substantial exhaustion of the filling therein, a lay, and means mounted thereon and movable manually into position to engage and hold out the binder-finger and prevent operation of the protector mechanism and also to prevent the operation of the replenishing mechanism, whereby upon removal of the shuttle the loom may be run without him drance to find the pick in which filling failure occurred, subsequent engagement of the replaced shuttle with the binder releasing the binder-finger from said manually-movable means, and a spring to return the latter automatically to inoperative position.
14. In a loom, shed-forming mechanism adapted to operate in a recurring cycle of three or more picks, a shuttle to lay the filling, means operative automatically by or through filling failure to stop the loom, protector mechanism, take-up mechanism, means movable manually into operative position to arrest the operation of the protector mechanism, whereby upon removal of the shuttle after automatic stoppage of the loom the latter may be run without hindrance to complete a shedding cycle and find the pick in which filling failure occurred, and means to prevent taking up of the cloth when the loom is run without the shuttle.
15. In a loom provided with automatic filling-replenishing mechanism, means, including a feeler to intermittingly engage the filling in the shuttle, to efifect the operation of said mechanism upon substantial exhaustion of the running filling, a shuttle to contain a supply of filling, protector mechanism, takeup mechanism, means manually movable into position to render the protector mechanism inoperative and to prevent operation of the replenishing mechanism when the 100m is run without the shuttle, and means to prevent taking up of the cloth when the loom is so run.
16. In a loom provided with automatic filling-replenishing mechanism, means, includinga feeler to intermittingly engage the filling in the shuttle, to efiect the operation of said mechanism upon substantial exhaustion of the running filling, a shuttle to contain a supply of filling, and means manually movable into operative position to prevent operation of the replenishing mechanism when the loomis run without the shuttle.
