ment longitudinally of-the shuttle when the,
filling is substantially exhausted on a detecting beat.
One of the objects of the present invention is to provide a feeler mechanism of the general type indicated, wherein the means for effecting movement of the feeler longitudinally of the shuttle when filling is substantially exhausted on a detecting beat, is placed under tension by engagement with a part carried by the lay on each detecting beat. This feature of the invention is carried, into practical effect in the present instance by means of a feeler controller which may engage the shuttle on its detecting beat and which is jointed to a member yieldingly connected to the feeler. The member between the controllerand the feeler is formed as a lever, one end .of which is connected to the controller and the other end of which preferably extends rearwardly and is connected to the feeler by a spring which is tensioned by movement of the controller on each detecting beat.
The above and other novel features "and combinations of parts constitutingthe present invention will best be understood from the following description and accompanying drawings of one good practical form of the invention.
In the drawings:
- Figure 1 is a perspective viewof the feeler side of a loom, some of the parts being omitted because they are not intimately associated with the feeler mechanism;
Fig. 2 is an enlarged plan view showing the action of the feeler mechanism when a working supply of filling is present in the shuttle on a detecting beat;
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;
F 1g. 4 is a cross section on the line 44 of Fig. 2.
The loom frame 1 has secured thereto the brackets 2, one at each side of the loom in which is mounted the transverse or rock shaft 3 which may be of usual construction.
'Rising from the rock shaft 3 is the arm 4 having pivoted thereto at 5 the latch 6 which, when-filling is substantially exhausted on a detecting beat, may be moved frontwarclly'by an operating member to rock the transverse or rock shaft 3 and thereby effect replenishment of filling, as, usual in this class of looms.
In the present instance the operating member consists of the cam follower 7 or a part connected thereto having a slide 8 which enters a recess or opening 9 in the end of the latch 6. Extending transversely of the latch 6 and normally positioned at one side of the opening 9 is the hunter 10 adapted to slide transversely of the latch in a suitable The feeler stand 14, in the present in-' stance, provides bearings for a controller 16. These bearings maybe variouslv formed and are conveniently provlded by the upstanding front and rear lugs 17 and 18 formed on a plate 19 which may be secured to the feeler stand. Each of the lugs 17 and 18 is provided with an opening through which extends the controller 16 with freedom for reciprocating movement therein. A spring 20 is interposed between the bearings 17 and a shoulder or pin 21 formed on or projecting from the controller 16, and the spring normallv acts to hold the controller in its rearward position, as indicated in Big. 1, but with permissive movement frontwardly when engaged by a part carried by the lay on a detecting beat. The plate 19 may be connected to the feeler stand 14 by means of the bolts 22, Figs. 2 and 3, which extend through a slot 23, whereby adjustment of the controller to properly engage a part carried by the lay on each detectingbeat may be accomplished.
Pivotally mounted on the feeler stand 14 at 24 is the feeler carrier 25 on which the feeler 26 is mounted for relative movement toward and from the front of the loom. Rising from the feeler carrier 25 are the front and rear bearing portions 27 and 28, respectively, through openings in which the feeler 26 extends. A spring 29 interposed between the front bearings 27 and a stop or pin 30 secured to the feeler member 26, serves nor mally to maintain .the feeler 26 in its rear.
ward feeling position. The above construction of the feeler carrier and the associated feeler provides a good practical form of means for permitting the feeler to be moved in a direction longitudinally of the shuttle. The feeler 26 is provided with teeth 31 on ts rear end portion, which enter the shuttle on each detecting beat and feel for the filling therein. These teeth may be differently formed, the essential being that when they detect a working supply of filling in the shuttle they will sink into the filling on a detecting beat and restrain movement ofv the feeler longitudinally of the shuttle, but when filling is substantially exhausted on a detecting beat they will slip along the surface of the filling carrier longitudinally thereof.
Mounted on thefeeler stand 14 at 32 is a lever which is independent of the feeler. One arm 33 of the lever extends laterally and is provided with an opening or slot 34 through which passes a pin 35 extending from the controller 16, the construction being such that upon movement of the controller toward or from the front of the loom, the lever will be moved upon its pivotal mounting. The other arm 36 of the lever extends rearwardly from the pivot 32 and "has connected to its rear end a rod 37. The rod 37 is jointed to the rear end of the lever 36 by a pin 38 which passes through the head portion 39 of the rod and is properly held in place by a nut 40, as indicated in Fig. 4.
The present invention contemplates that the rear end'portion of the lever arm 36 shall have yielding connection with the feeler and in the presentdnstance of the invention this is effected by a spring 41 surrounding the rod 37 and having one end bearing against a shoulder 42 and the other end against a collar 43 loosely mounted upon the rod 37 The rod 3?.extends through an opening 44 in a lug or flange 45 projecting upwardly from the feeler carrier 25 and is provided with a head or stop 46, the construction being such that upon movement ofthe rear end 36 of the lever from the dotted to the full line position, Fig. 2, when the feeler is restrained from its movementlongitudinally of the shuttle, the spring 41 will be compressed and placed under tension, and such tension will be transmitted to the feeler through the connections'described, the rod 37 at such times being pushed laterally through the opening 44 of the feeler carrier.
Thefeeler is connected to the hunter 10 by means of a rod 47, one end of which is jointed at 48 to the upstanding flange or lug 45 mounted on the feeler carrier, the construction being such that should the feeler be moved longitudinally of the shuttle, the rod 47 will be moved to place the hunter 10 in the path of movement of the slide 8, Fig. 1, and thereby effect frontward movement of the latch 6 and rock the transverse shaft 3 to effect replenishment of filling.
Should'the feeler be moved in the manner stated to effect replenishment of filling, it is desirable that the feeler be returned to its normal feeling position, as indicated in Fig. 1, as the lay goes back. This is effected in the present instance by means of the setting stop 46 on the rod 37, which, as the rear end portion 36 of the. lever hereinbefore described, is moved to the left in the dotted line position. Fig. 2, engages the flange 45 and pulls the feeler into its normal feeling position. I
The lay 49 may be of usual construction and provided with an opening 50 in its front wall which coincides with an opening 51 formed in the adjacent wall of the shuttle 52 and registering with the opening 50 when the shuttle is properly boxed at the detecting-side of the loom.
Vhen a working supply of filling is present in the shuttle on a detecting beat, the feeler 26 enters the shuttle and the teeth 31 thereof sink into the filling. The controller 16 then engages a part carried by the lay, preferably the shuttle wall, and is moved frontwardly thereby: The frontward movement of the controller 16 effects a rocking movement of the lever from the position indicated in dotted lines to the position indicated in full lines, Fig. 2, and thereby tensions the spring 41 which tends to move the feeler in a direction longitudinally of the shuttle. Owing to the presence of a working supply of' filling, however, the feeler is restrained from responding to the tension of the spring 41. When the filling is substantially exhausted on a detecting beat. the feeler 26 will again contact with the surface within the shuttle and the controller 16 will likewise be engaged and moved frontwardly by the shuttle. The frontward movement of the controller acting through the lever thereupon tensions the spring 41, as before, and effects movement of the feeler in a direction longitudinally of. the shuttle, as indicated in Fig. 3. This movement of the feeler is transmitted through the rod 47 to the hunter 10 which is thus placed in the path of the slide 8 on the operating member to set in action the train of mechanism for replenishingfilling. As the lay goes back and releases the controller to rearward movement under the action of its spring 20, the pin 35 acting upon the lever arm 33 returns the lever to its dotted line position, Fig. 1, thereby pulling upon the rod 37 and causing the stop 46 to return the feeler to its initial feeling position.
