STOPPING MECHANISM FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 720,1 17, dated February 10, 1903.
Application filed December 5, 1902- To Cl/ZZ whom it may concern:
Be it known that we, JOHN V. OUNNIFF and EDWARD CUNNIFF, citizens of the United States, and residents of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in Stopping Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object the production of means for readily indicating to an attendant the cause of the stoppage of a loom, whether it be due to a fault in the warp or [5 filling or due to the operation of the protector mechanism. It is well known that the shipper of a loom is released upon the occurrence of any of these faults to stop the loom, and the more readily the attendant can discover :0 the particular cause of stoppage the more quickly can the fault be remedied and the loom started. A device for making such a stop indication forms the subject-matter of United States Patent No. 623,174, dated April 18, 1899, and will be hereinafter referred to,
the construction and arrangement of the stopindicator in our present invention being simplified and improved, as will more fully appear hereinafter.
Figure 1 is a left-hand side elevation of. a portion of a loom with one embodiment of the present invention applied thereto,the notched holding-plate being shown in section. Fig. 2
is an enlarged top or plan view thereof with the shipper in section. Fig. 3 is a perspective detail of the stop-indicator detached, and
Fig. 4 is a perspective detail of the fulcrum end of one of the knock-off levers which cooperates with the stop-indicator.
Referring to Figs. 1 and 2, the notched holding-plate N for the shipper S, the frog-- holder F, dagger f Fig. 1, frog f, and the cooperating knock-off lever f, constituting usual protector mechanism and operative when the shuttle is improperly boxed to release the shipper, are and may be of usual construction.
The filling-fork Z9 its slide b moved outward by the hook I) on the weft-hammer A Serial No.. 133,938. (No model.)
Fig. 2, upon filling failure, the latch d to engage and move a knock-off lever, to be referred to, upon a second successive outward movement of the slide If, the operating-shaft d for the filling-supplying mechanism, (not shown,) and the arm 0 on said shaft may be and are all as in the patent referred to and operate in a similar manner.
A knock-off lever 12 is fulcrumed at one end on an upright stud b on the breast-beam A and is retained thereon by a nut 19" and friction-washer 12 Fig. 2, its end being extended into the path of the latch d. The end of the leveradjacent the fulcrum-stud is flattened and enlarged, as at b, Fig. 4, and provided with a radial lug b A stop-indicator is herein shown as an arm h, having an enlarged and flattened head h, Fig. 3, and near its outer end it is provided with a depending, thin, and fiat finger W, the indicator being fulcrumed on the stud b the enlargement b of the knock-off lever 19 resting upon the head h, which latter is provided with an u pturned shoulder 72 in the path of the lug 19 A single stud is thus made available for both the knock-off lever b and the stop- 75 indicator, the friction-washer b preventing undue movement. The holding-notch n, Fig.
2, is increased in width for a portion of its length, as at n, to receive the depending finger 7L2, and when the shipper is in the notch, as in Figs. 1 and 2, the finger h is interposed between the shipper and the upper end of the protector knock-off lever f, as clearly shown in Fig. 1. At the same time the shoulder h abuts against the lug b of the knock-off lever 19 which is then in its normal position, theposition of the parts when the loom is running properly being shownin full lines, Fig. 2.
If the protector mechanism is operated, the leverf is turned to push inward against the finger 71, turning the stop-indicator h into dotted-line position, Fig. 2, and releasing the shipper to stop the loom. The knock-off lever 79 is not moved, however, so that by noting that fact the attendant knows that the fault is in the shuttle. If, however, the filling-fork mechanism has operated, the latch d will move the lever b into dotted-line po sition, Fig. 2, and the lug b acts on the shoulder to turn the stop-indicator into dottedline position and release the shipper. Then both lever b and stop-indicator will be in abnormal position, and the attendant knows thereby that the fault was with the filling.
Referring to Fig. 1, a link 9 forming part of asuitable warp-stop-motion instrumentality, serves to at times move a rocker-arm g, having an inclined slot g in its upper end to receive the lower end of the shipper below its pivot s, all substantially in the patent referred to. Upon occurrence of a warp fault the upper end of the rocker-arm g is swung in the direction of arrow 10, Fig. 1, and the inclined edge of the slot will act on the shipper below its fulcrum and move the upper end of the shipper out of its holding-notch tostoptheloom. Thestop-indicator,however, is not moved from its normal position, so that the attendant knows that neither of the knockoif levers f or b has released the shipper and that the fault is in the warp. When the lever b moves the stop-indicator, the shoulder 71 and lugs b are close together; but when the leverf moves the indicator said lug and shoulder are separated, aiding, the attendant in determining the fault. The free end of the stop-indicator is curved, as at If, to be moved automatically into the part 01' of the holding-notch by the shipper when the latter is moved into running position.
In a loom comprising a plurality of independent instrumentalities arranged to operate individually, as hereinbefore set forth, the position of the stop indicator denotes clearly to the attendant which instrumentality operated to efiect stoppage of the loom, so that the particular fault can be at once located and the trouble remedied without delay.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In a loom comprising a plurality of inde pendent instrumentalities to operate individually, a shipper, a knock-oiI" lever for each instrumentality,astop-indicatorcofulcrumed with one of said levers and actuated by 0perative movement thereof to release the shipper, and a finger on the indicator interposed between the shipper and the other lever, the
stopping position of the indicator relative to the former of said levers denoting which instrumentality has operated to release the shipper and stop the loom.
2. In a loom comprising a plurality of independent instrumentalities to operate individually, a shipper, a knock-off lever for each instrumentality, a swinging stop-indicator having a finger interposed between the shipper and one of said levers and adapted to be engaged adjacent its fulcrum by the other lever, the stopping position of the indicator relative to the latter lever denoting which instrumentality has operated its knock-oif lever to effect release of the shipper.
3. In a loom comprising a plurality of independent instrumentalities to operate individually, a shipper, a knock-01f lever for each instrumentality,astop-indicator cofulcrumed with one of said levers, and having a shoulder adjacent its fulcrum, and a finger on the indicator interposed between the other lever and the shipper, operative movement of the cofulcrumed lever acting upon the shoulder to swing the indicator and release the shipper, the latter being also released when its finger is engaged and moved by operative movement of the other lever.
4. In a loom, a shipper, its notched holding-plate, means operative upon a warp failure to act directly upon and release the shipper, protector mechanism, mechanism operative upon filling failure, eachof said mechanisms including a knock-off lever, a stop-indicator pivoted 011 the fulcrum of one of said levers and actuated by operative movement thereof, and a finger on the indicator interposed between the shipper and the other lever, operative movement of the latter acting through the finger to release the shipper, the angular position of the stop-indicator relatively to the cofulcrumed lever denoting whether filling failure or the protector mechanism has operated to effect shipper release.
5. In a loom, a shipper, a knock-01f lever actuated by or through filling failure, and having a lug adjacent its fulcrum, a stop-indicator pivotally mounted on the latter and having a shoulder to cooperate with the lug and release the shipper, a second knock-off lever actuated by or through improper boxing of the shuttle, and a finger on the free end of the stop-indicator, interposed between the shipper and said lever, actuation of the latter operating through the finger to release the shipper, the position of the stop-indicator relative to the knock-oil? lever having the lug denoting which of the levers has operated to release the shipper.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
