EEELER MECHANISM FOR AUTQMATIC FILLING-REPLENISHING LOOMS.

Specification of Letters Patent.

Application filed April 9, 1914. Serial No. 830,784.

i which the following description, in connec tion with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object the production of a novel means for detecting substantial exhaustion of filling in the active shuttle of the loom and thereupon automati cally effecting a change in. the operation of the loom,such as the automatic replenishment of the filling, or the automatic stoppage of the loom.

In the preferred embodiment of the inven-.

tion illustrated herein this invention is shown as applied toa loom of the Northrop type which has been adapted to use bobbins having slotted barrels into which the feeler arm is projectedwhen the filling is so far unwound from the bobbin barrel as'to uncover said slot or a portion thereof. In such automatic filling replenishing looms the detection by the feeler of absence of filling upon the filling carrier usually causes a movable member to be positioned in the path of the shuttle box or some other element carried by the lay which causes the actuation of means :to initiate the operation of the transfer mechanism. In'such looms a careful and accurate adjustment of the test:

ing mechanism isrequired to maintain the same in operative condition and even when the parts are properly adjusted transfer is sometimes effected prematurely by reason of the vigorous action of the lay.

One object of .6 invention therefore is to provide a simple but very sensitive mechanism for detection of substantial exhaustion of filling which will not require constant adjustment but which will act with certainty.

Another of the objects of the invention is to provide mechanism adapted to the Northrop type of loom through which the actuation of the transfer mechanism is initiated by mechanism other than the movement of the lay preferablyby means actuated from a cam upon the take up shaft of the loom whereby the likelihood of premature actuation of the transfer mechanism is avoided.

Other objects of the invention and the pa -lire thereof will more fully appear from the following description and accompanymg drawing and will be particularly pointed out in the annexed claims; I

In the drawings: Figure 1 is a plan View of a portion of a loom embodying my invention, Fig. 2 is a vertical side elevation illustrating the relative position of the feeler mechanism, the transmitter and a preferredmeans for actuating the same, Fig. 3 is a detail viewof the feeler and the means for supporting the same.

llatented A ug. 24k, 1915. v

In the drawings, Fig. 1 illustrates 'the' grdinary lay l,'having a shuttle box 2 inclosng a shuttle 3 provided with a-suitable fillmg carrler 4, preferably a bobbin having a slot 5 in its barrel near the base thereof, the

shuttle and shuttle box being provided respectively with slots 6 and 7 through which the end of the feeler is adapted to pass. The lay is mounted in the usual manner and the shuttle carried thereby is adapted to be replenished from a battery 8 from which the filling carrier is delivered by a transfer arm 9 which is actuated through a controlling rock shaft 10 in the usual manner.

The loom is provided with the usual filling fork mechanism 12 and weft hammer 13 for arm-16 projecting upwardly from'the con-- trolling rock shaft 10. I

The breast beam is preferably provided with the usual extension 17 having a notched 'slot 18 to receive a shipper lever 19, a lever 20 mounted upon a pivotQl being'adapted to disengage the shipper from the notch through the automatic operation of the stop mechanism in the usual manner.

As illustrated in the drawing a transmitter 25 is provided which is adapted to raise the latch 15 into engagement with a notch in the vibrating actuator or w eft hammer as is the case in the ordinary construction of. the Northrop automatic loom but the character of the transmitting lever as embodied in my invention is modified and the -means for actuating it are derived from a suitable constantly moving part of the loom other than the lay, such as a cam upon the tak'oup shaft, the operation ofthe transmitter being merely controlled by the action of the feeler.

In the preferred form of invention illustrated herein the one end of the transmitterf extends beneath the'latch 15 in the *usual manner but its opposite end is pivoted upon a lug 26 projecting laterally from a bracket 27 which is rigidly secured to a lug 28 extending upwardly from the extension I 17, suitable lugs 29, 30 serving to guide the free end of said transmitter; The transmitter is provided intermediate of its ends with a laterally projecting stud'32 upon which is mounted a'vibrating member con-.

link 36 causes the vibrating member nor-' mally to oscillate idly upon its pivot 32, but when the end of the free arm 35 is restrained the reciprocating link causes a bodily movement of the lever raising the pivot 32 and thereby actuating'the transmitter 25 to position the latch 15 in the path of the vibrating actuator or weft hammer. Means for thus restraining the movement of the free end of the'vibratorare preferably controlledfrom the feeler in the following manner: The feeler 40 preferably is slidably mounted in a bearing 41 extending laterally from a bracket 42 which is-adjustably secured. to the extension 17 said bracket be- 85 ing provided at its lower end with an ear 43 having a stud 45 upon which an arm 44 is pivotally mounted. The arm 44 is pivotally attached at its upper end to the feeler 4O and is provided at its lower end with a lat- 0. eralarm having a counterweight 46 which normally holds the feeler in feeling position. A suitably cushioned lug 47 projecting from the bracket 42 limits the movement of the arm 44 in one direction and a resili- 45 cut member 48 preferably constructed of heavy 'leather serves to arrest the movement of the arm 44 when thrust forward by the feeler by its engagement with the filling on the bobbin. The arm 44 is provided with 50 a laterally extending ledge 49 which is held normally beneath the end 35 of the vibrator, but is withdrawn from said position whenever the arm 44 is rocked by the feeler; upon its engagement with the filling carrier as the lay beats up.

When the filling has become sufficiently exhausted, to expose the slot 5 in the bobbin barrel the feeler 40 will not be pressed forward and the ledge 48 will remain in the path of the free end 35 of the vibrator thus restraining the downward movement thereof. By reason of this restraint the vibrator thereof and with it the latch 15 into the path of the vibrating controller or weft hammer. Upon the forward movement of the latter the arm 16 of the shaft 10 will be forced forward thus positioning the dog of the transfer mechanism in the path of the lay in. the usual manner to cause the'transfer arm to deliver a new filling carrier from the hopper into the shuttle.

It will'be observed that by reason of the fact that the feeler merely causes the vibration of the pivoted arm 44 which is provided with a relatively wide ledge 4 and of the.

'furtherfact that a considerable amplitudeof movement is permitted when the feeler ggo entersthe-slot in the bobbin, the delicate adjustments which have been heretofore necessary are eliminated and the constant attention required thereby avoided.

g It will be obvious that if desired the mechanism above described may be caused to cooperate with the shipping mechanism of the 110m in such a manner as to cause the stoppage of the loom upon the detection of exhaustion of filling.

It will also be obvious that the vibrator 34, 35 may be actuated from any rotatable shaft of the loom and. that its actuation" from the take up shaft as disclosed herein is merely illustrative of a convenient means, probably the most convenient means, for actuating the same.

It. isto be understood therefore that the embodiment of the invention herein -is merely illustrative and is not restrictive and that it may be embodied in various other forms of mechanism.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: 5
