To all whom t may concern:

"Be it known that, I, ALVINv R. DILLABER, a citizen of the United States, and a resident of Grosvenor Dale, county of vWindham and State of Connecticut, have invented an Improvement in Feeler Mechanism 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, and more particularly to feeler mechanisms of the' type shown, described and claimed in the patent granted to Edward S. Stimpson, No. 1,309,226, dated July s, 1919.

In the feeler mechanism of the patent to which reference has been made, the feeler is supported to enter the shuttle on each detecting beat in a .direction inclined to the ylongitudinal axis ofthe shuttle, or inclined to the path of'lay movement, and is held from movement lengthwise along the lillingcarrier or bobbin by the filling or weft when a working supply is present in the shuttle, and is moved longitudinally along the filling carrier or bobbin by the frontward pressure when the filling or weft is substantially exhausted. In the feeler mechanism of the S-timpson patent the feeler extended rearwardly through a controller which was connected to a train of mechanism for effectng replenishment of lling when the feeler moved the controller laterally, ldue to the movement of the tip of the feeler along the lilling carrier or bobbin, and a spring was employed to move the feeler into its rear or feeling position as the lay retreated. The present'invention is a further development of the character of feeler mechanism disclosed by the Stimpson patent and hasfor one of its objects to dispense with the connection between the controller and the latch of the patent, and also to provide means of a simple and readily accessible character for returning the feeler to its normal feeling position as the spring.

returns the feeler rearwardly after a detectingbeat.

The linvention will best be understood from the following description in connection with the accompanying drawing, which shows a good practical embodiment of the present invention.

EEELEEMECHANISM Eon Looms.

Specification of Letters Patent. Patented June 20, 1922.l I l Application inea october 11, 1919. serial No. 329,974.

.the present invention associated therewith;

Flg. 2 1s a plan view, parts being shown in section, and illustrating the action of the parts when the filling or weft is substan- -tially exhausted;

Fig. 3 is a cross section on the line 3 3 of Fig. l, showing more particularly the controller.

'The loom frame 1 is provi-ded with brackets 2 in which is mounted thetransverse or rock shaft 3 having an arme extending upwardly therefrom, to which is connected the latch y5, the rear end 6 of which is adapted to engage at. times with an operating member 7 which may be the cam follower or a part connected thereto', as usual in this type of loom. t

i IThe loom frame has extending therefrom the bracket 8 on which is adjustably secured the feeler stand 9. The feeler stand 9 supports the feeler and in the present instance it is provided with a flange 10 in which is formed a slot l1 throughwhich passes the bolt 12 for adjustably securing t'he feeler stand or feeler support 9 in desired adjusted position.

The feeler 13 is mounted on the feeler stand or Support to enter the shuttle 14 on wall of the shuttle when the latter is in the detecting box.

The feeler stand or support 9, at its rear portion, is provided with a gui'deway' for receiving the controllerwhich is mounted inI the guideway for movement laterally by the feeler, as' will more fully appear. In the present instance of the invention, the feeler stand or support 9 has its top wall'lS provided with a guidewayl9 and. its underwall 2O lprovided with a guideway 21 in which is mounted the controller 22. The

controller 22 may be moved laterally in the guideway of the support or stand 9 and is provided with a slot 23 through which passes the feeler 13, the construction being such that. when a working supply of filling is present in the shuttle on a detecting beat, the feeler 13 will not cause lateral movement of the controller, but when -the filling is substantially exhausted on a detecting beat and the feeler moves longitudinally of the lling carrier or shuttle under the frontward pressure or push, then the controller 22 is moved laterally.

The controller 22 has an inclined end portion 24, Fig. 3, which is adapted to engage a transmitter 25, which, in the present instance of the invention, has a toe portion or projection 26 over which the inclined end 24 of the controller may ride when the controller is moved laterally by the feeler upon indication of substantial exhaustion of filling. The controller 25 is pivotally mounted at 27 on a support 28 rising from the loom frame or bracket 8, and its end 29 extends.

under the latch 5, the construction being such that if the transmitter 25 'is actuated by theinclined end 24 of the controller when it is moved laterally by the feeler, the latch 5 will be placed in the path of movement of the operating member 7 and filling replenish'- ment will be initiated or effected.

' In the S'timpson patent to which reference has been made, the controller was positively connected to a train of mechanism for effecting replenishment of filling, but in the present instance the controller is not connected to the train of mechanism but the inclined end portion 24 is related to such mechanism so that by lateral movement of the controller the inclined end portion of the controller rides over and depresses the end of the transmitter or an element con-y nected to the train of mechanism and initiates replenishment of filling.

The rea;` end portion of the stand or support 9 is slotted as at 30 to permit lateral movement of the feeler, and a stop 31 serves to limit the lateral movement of the feeler in the slot.

The lateral movement of the controller by the feeler as hereinbefore described, is effected in a direction inclined tothe longitudinal axis of the shuttle or path of lay movement, so that the inclined end 24 of the controller rides over the end or toe 26 of the transmitter and effects movement thereof to set in action the train of mechanism for initiating replenishment o f filling.

A spring 32, preferably placed within the feeler stand 9 and surrounding the feeler 13, has one end bearing against the front wall' 33 of the feeler stand and its other end against a pin or shoulder 34 secured to the feeler, the construction beingsuch that the spring 32 normally holds the feeler in its rearward position land serves tomove it backwardly after a detecting beat.

. The feeler 13 passes through a front bear-yV feeler 13 to move towards and from thev front ofthe 'loom and also to swing laterally. The feeler 13 has its front end portion threaded at 36 and limiting or stop nuts 37 are adjustably mounted on the outer end 36 of the feeler to limit its rearward movement under the impulse of the spring32. 'In lorder that the feeler may be moved laterally, to the left, as the spring 32 returns it to rearward position after an indication of substantial exhaustion of filling, the present invention provides the shoulder 38 on the front portion of the stand or support 9 against 4which the face of one of the nuts 37, or a washer 39, is caused to bear under the impulse of the spring 32, as the feeler returns to its rearward position. This functional action of the shoulder 38 will be best appreciated from Fig. 2, wherein 'the feeler is shown as havingl moved laterally or lengthwise along the filling carrier, the filling being substantially exhausted. kAs the feeler, Fig. 2, moves rearwardly, the washer 39, in the presentinstance, will engage the shoulder 38 of the feeler stand and cause the feeler to be moved or swung laterally to the left into proper feeling position.

The feeler 13 has a toothed end portionv l40 which, on each detecting beat, meets a surface `within the shuttle. When a working supply of filling is present, the toothed end portion 40 of the feeler sinks into the filling and prevents movement of the end of the feeler lengthwise along the filling carrierias the lay beats up. When, however,

the filling is 'substantially exhausted on a detecting beat and there is not sufficient, filling in the shuttle to prevent movement of the toothed end 40 along the filling carrier, the end 40 of the, feeler will move laterally along the surface of the filling carrier under the frontward pressure thereof and cause the controller to be moved laterally in its path inclined to the longitudinal axis of the shuttle and thereby effect replenishment of filling.
