FEEL-ER MECHANISM FOR LOOMS.

' Specification of Reissued Letters Patent. Reissued J 6 1922 Original No. 1,392,806, dated October 4, 1921, Serial No. 379,267, filed May 6, 1920. Application f r issue filed April 13, 1922.

To all whom it may concern:

Be it known that I, ISAAC SNow, a citizen of the United States, and resident of Lawrence, in the county of Essex and State of Massachusetts, have invented an Improvement in Feeler Mechanisms for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to feeler mechanisms for looms, whereby filling is replenished when that in the active shuttle becomes substantially exhausted. Sensitiveness in the feeler is required in order to prevent premature replenishment of filling, and likewise to effect replenishment of filling when engagement with the filling when a working supply of filling is present in the shuttle on a detecting beat. The present invention is directed more particularly to this type of feeler mechanism, and aims to provide such a feeler mechanism which shall answer the requirements both as to the presence of the working supply of filling in the shuttle, and its substantial absence on a detecting beat.

An important feature of the present invention, therefore, consists of a feeler which is mounted for bo'dily movement toward and from the front of the loom on a feeler carrier and which has a filling engaging surface that is movable in a direction longitudinally of the shuttle due to the bodily longitudinal movement, such movements being effected when the filling is substantially exhausted on a detecting beat, and prevented by engagement of the feeler with the filling when a working supply is present.

The above and. other novel features and combination of parts will be hereinafter described in connection with the accompany- Serial No. 553,199.

mg drawings which show one good, practical form of the invention, wherein F igure 1 is a perspective view of the feeler side 0f the loom, showing more particularly the ad acent end of the lay and the feeler mechanism;

Fig. 2 is a plan View on an enlarged scale, of the feeler mechanism showing its action when a working supply of filling is present in the shuttle on a detecting beat;and

Fig. 3 is a view similar to that of Fig. 2, showing the action of the feeler mechanism when the filling is substantially exhausted on a detecting beat.

The loom frame 1 has mountedthereon the brackets 2, one at each side of the loom, in which is supported the transverse or rock shaft 3 which controls the filling replenishing mechanism, as usual in this class of looms.

Rising from the transverse or rock shaft 3 is the arm 4 to which is pivoted at 5 the latch 6, the rear end portion of which is adapted at times to be engaged by an operatmg member 7 preferably formed as part of or connected to the cam follower or weft hammer. The latch 6 may be variously formed, but in the present instance it has pivoted thereto at 8, the rear engaging end portion 9 with which the operating member 7 makes contact when the filling is to be re-- plenished. Extending from the portion 9 is a finger 10 which overlies one arm of a bell crank lever 11 pivotally mounted at 12 to a support 13 secured to the loom frame at 14, the construction being such that movement of the bell crank under the control of a transmitter 15 will place the rear end of the engaging portion 9 of the latch in the path of the operating member, as'will more fully appear. The transmitter 15 is connected to the bell crank at 16, and the construction of parts so far described is or may be of usual character.

The lay 17 is provided with. the usual shuttle-box 18, the front wall of which has an opening 19. The shuttle 20 carries the usual filling wound upon a filling carrier or bobbin 21. The wall of the shuttle is provided with an opening 22 which, when the shuttle is inthedetectinghon, registerswith- I, the opening" 19 otthe front-Wall of the] shuttle-box for the entrance of the t'eelen' Extendin -#9 h I 1 rmfnejis the.

1. In a feelermechanism for looms, the combination of a feeler carrier mounted for movement toward and from the front of the loom, a rack which is fixed relative tothe feeler carrier, a feeler that is mounted on the feeler carrier for bodily movement frontward relative thereto and for movement in a direction longitudinally of the shuttle and which is held from such movements by engagement with the filling on a detecting beat until the filling is substantially exhausted, and rack teeth on the feeler which engage the fixed rack on the feeler carrier.

2. In a feeler mechanism for looms, the combination of a feeler carrier mounted for movement toward and from the front of the loom, a feeler that is mounted on the feeler carrier for rotative movement relative to the longitudinal axis of the shuttle and for bodily movement in a frontward direction relative to the feeler carrier and that is held from said movements by engagement with the filling on a detecting beat until substantial exhaustion thereof, and means for effecting replenishment of filling when the feeler is rotated and moved bodily relative to the feeler carrier.

3. In a feeler mechanism for looms, the combination of a feeler carrier mounted for movement towards and from the front of the loom, a feeler mounted for movement rela. tive to the carrier in two directions, one a turning movement relative to the longitudinal axis of the shuttle due to the frontward pressure upon the feeler when the filling is substantially exhausted on a detecting beat and the other a bodily movement relative to the carrier which is dependent upon the turning movement, and means for effecting replenishment of filling when the feeler partakes of such movements on a detecting beat.

4. In a feeler mechanism for looms, the combination of a feeler carrier, a feeler mounted on the feeler carrier for rotative movement relative to the longitudinal axis of the shuttle and held from such movement by the filling on a detecting beat until the filling is substantially exhausted, connections between the feeler and feeler carrier which effect bodily frontward movement of the feeler relative to the carrier due to the rotative movement of the feeler, and means operated by frontward bodily movement of the feeler relative to the feeler carrier for effecting replenishment of filling.

5. In a feeler mechanism for looms, the combination of a feeler carrier, a feeler mounted on the feeler carrier for movement of its filling engaging surface longitudinally of the shuttle and held from such movement by the filling on a detecting beat until the filling is substantially exhausted, connections between the feeler and feeler carrier comprising teeth on the feeler and a rack on the feeler carriage, which efi'ect bodily frontward movement of the feeler relative to the carrier due to the movement of the filling engaging teeth of the feeler longitudinally of the shuttle, and means operated by frontward bodily movementof the feeler relative to the feeler carrier for effecting replenishment of filling.

6. In a feeler mechanism for looms, the combination of a feeler carrier having a housing, feeder mounted within the housing for movement bodily therein and for rotative movement relative to the longitudinal axis of the shuttle by the frontward pressure and held from such movements by engagement with the filling on a detecting beat until substantial exhaustion of filling, connections between the feeler and feeler carrier for causing bodily frontward movement of the feeler relatively to the feeler carrier when it is rotated, relative to the longitudinal axis of the shuttle on a detecting beat and means for effecting replenishment of filling.

7. In a feeler mechanism, the combination of a feeler carrier, a feeler mounted for rotative movement and rack and pinion connection between the feeler and feeler carrier for converting the rotative movement of the feeler into a rolling movement relative to the feeler carrier, and filling engaging teeth for holding the feeler from moving' relative to the carrier until filling is substantially exhausted.

S. In a feeler mechanism for looms, the combination of a feeler carrier mounted for movement toward and from the front of the loom, a feeler which is mounted for rotative movement relative to the longitudinal axis of the shuttle and frontward bodily movement relative to the carrier by the frontward pressure of a surface within the shuttle on a detecting beat when the filling .is substantially exhausted, and means connected to the feeler for effecting replenishment of, filling when the feeler is so moved on a detecting beat.

9. A feeler mechanism comprising in combination, a feeler carrier, a rack secured to the carrier, a feeler having rack teeth engaging the fixed and filling eng'agingteeth for engaging the filling in the shuttle, and means for normally holding the feeler in feeling position and movable by the feeler when the cooperating teeth of the feeler and rack cause frontward movement of the feeler due to the filling engaging teeth moving along the filling carrier 011 a detecting beat.
