SPEGTFICATION forming part of Letters Patent No. 648,986, dated May 8, 4

Application filed October 23, 1899. Serial No.784,461. (N0 model.)

To all whom it may concern:

Be it known that I, JONAS N ORTHROP, of l'lopedale, county of W'orcester, State of Massachusetts, have invented an Improvement. in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention relates to looms provided with automatic filling supplying or changing mechanism whereinunder certain conditions a fresh supply of filling is automatically effected, such a loom forming. the subject-mat ter of United States Patent No. 529,940, dated November 27, 1894. It has been found desirable in such looms to make provision for effecting such filling change or transfer prior to the complete exhaustion of the filling in the shuttle, the filling-supplying mechanism being controlled as to its operation by a feeler which cooperates with the filling in the shuttle, the feeler performing the desired function when the filling has been exhausted to a Various feeler mech anisms have been devised, among Others that shown in United States Patents Nos. 600,016 and 626,187, the feeler, located at one Side of the loom, encountering the filling in the shuttle each time the latter entered the adjacent shuttle-box, the movement of the lay being made efiective through engagement of an actuator with the shuttle-Wall to attain the operation of the means controlling the fillingsupplying mechanism when the feeler had detected the predetermined exhaustion of the filling. It has been found in. practice that the direct Operation of the controlling means by the feeler introduces a variable and objectionable factor in the operation of the apparatus, objectionable because of its nonuniformity in action and also because the parts are subjected at times to undue strain. Again, in either of the feeler patents referred to it will be manifest that the relative movement Of certain parts must be very slight, so that the Setting oradjustment must be had between narrow limits, and if this slight movement be overstepped accidentally, due to rapid operation, the filling transfer is effected too soon. In my present invention the evil effects of direct action have been entirely eliminated, the feeler itself playing no direct part in the actuation of the controlling means for the filling-supplying mechanism. The feeler is arranged to engage the filling in the shuttle as the lay beats up, and filling-induced movement of the feeleri. 6., due to such engagementis completed when the lay is fully forward. So long as there is a proper quantity of filling in the shuttle no change of operation of the filling-supplying mechanism takes place; but when the filling has been ex hausted to a predetermined extent the feeler will have avery slight filling-induced movement or none at all, permitting the engage ment of a member of the controlling means with a vibrating part of the loom, preferably the weft-hammer, which has a comparatively slow movement. Such engagement of the member of the controlling means and the actuator therefor operates to effect a change of filling, as will more readily appear hereinafter, and manifestly without the objectionable features due to the direct action of 'a rapidlymoving part. The construction hereinafter to be described also permits of very fine setting, so that the amount of filling-waste is reduced to a minimum.

The relation between the actuator and the cooperating member of the controlling'means is unchanged in my present invention from the time the maximum amount of filling is in the shuttle up to the point of exhaustion, Whereat change of filling is to take place, although it will be manifest that the filling-in- :duced movement of the feeler will vary as the volume of filling changes.

In order to absolutely obviate a premature transfer of filling and consequent waste thereof, it is necessary after the feeling movement to prevent such rapid return of the feeler to normal position as would permit the engagement of the actuator with the cooperating member of the controlling means, or, in other words, to retard the return of the feeler until the actuator has passedthe critical point in its stroke. If no such provision be made, it is possible, with the rapid movement of the lay and the relatively-slow motion of the actuator, for the feeler to at any time return to normal position before the actuator has passed such critical point, permitting the cooperatin g member of the controlling means to be engaged by the actuator to thus effect filling change. As will fully appear hereinafter, I have so arranged and constructed the mechanism that the said member of the controlling means will prevent return of the feeler to normal position after each filling-induced or feeling movement until the actuator has passed the critical point in its stroke.

The usual weft or filling fork is herein utilized to stop the loom upon breakage of the filling or its accidental exhaustion.

Figure 1 is a top or plan view, centrally broken out, of a portion of a loom, including the lay and breast beam and filling-supplying mechanism, with one embodiment of my present invention shown in connection therewith. Fig. 2 is an enlarged transverse sectional viewof the loom, taken on the lineccac, Fig. 1, looking toward the right, the fillingsupplying mechanism at the far side of the loom being omitted. Fig. 2 is a detail in section, to be described, of the feeler-support. Fig. 3 is a similar view, also enlarged, on the line ww', Fig. 1, showing the parts in normal position before the feeler has felt the filling in the shuttle. Fig. 4 is an enlarged top or plan view of the weft or filling fork, its slide, and the latch-like member, with its support, forming part of the means forcontrolling the operation of the filling-supplying mechanism. Fig. 5 is an opposite side view of the parts shown in Fig. 3; and Fig. 6 is a perspective detail, enlarged, of the sliding latch-support and the guide therefor to-be described.

The loom-frame A, breast-beam A lay A the filling-feeder F, Fig. 1, comprising, es sentially, connected rotatable plates suitably shaped to receive the ends of the filling-carriers b, the transferrcrf, mounted upon the stud f, and the operating or controlling shaft (1, adapted to be rotated in the direction of the arrow 20, Fig. 3, to effect a change of filling, and normally held in the position shown in said figure by the spring S are and may be substantially all as represented in said Patent No. 529,940, whereinlike letters and numerals are used to designate like parts, the parts hereinbefore referred to being operated substantially as provided for in said patent.

I have shown in Fig. 1 the fillingfeeder F as located at one side of the loom and adapted to transfer a fresh supply of filling to the shuttle when in the adjacent shuttlebox, while the feeler mechanism is located at the other side of the loom, the feeler cooperating with the filling in the shuttle when the latter is in the box B The usual notched l1olding-plate N for the shipper-lever N has secured to it a stand a, slotted at right angles to the breast-beam, .as at to, Figs. 2 and 2, and forming a support for an upright sleeve a which rests and is adapted to be moved upon the top of the stand, an car a depending from the stud into the slot at, having an offset threaded hole therein to be entered an d engaged by a rotatable and non-longitudinally-movable adj Listing-screw of. A headed stud a is passed up through the bottom of the slot a and the sleeve, the head (0 resting against the bottom of the stand, while a nut 5 and washer 6 on the upper end of the stud bear against the top of the sleeve and serve to clamp the latter in adjusted position on the stand a. Upon the reduced part a of the sleeve, Fig. 2, I have mounted with a loose fit the hubf of the feeler, shown as a substantially L-shaped arm f the nut and washer on the stud retaining the feeler in place while permitting it to rock freely. The sleeve forms a long bearing for the feeler, adding greatly to the steadiness of movement of the feeler and increasing the strength and durability of the parts. By means of the adjusting-screw the sleeve may be moved toward or away from the breast-beam,to thereby set or adjust the feeler according to thestroke of the lay or the size of shuttle which may be used. The opposite or inner end of the feeler is extended to form an arm f, the free end of which is normally held against an abutment or stop b located on a stand, to be described, seen red to the breast-beam, a suitable spring s surrounding the sleeve a, normally maintaining the feeler in the position shown in Figs. 1, 2, and 3.

The extremity of the i'eelerf is preferably extended laterally, as shown clearly in Fig. 1, and the feeler is adapted to pass through an aperture 3 in the front wall of the shuttle box B as the lay heats up.

The shuttle is provided with a slot 4 in its side wall, (see Fig. 2,) and when the shuttle is positioned in the box, as in Fig. 1, the feeler will pass through the slots 3 and 4 and will bear upon the mass of filling on the filling carrier or bobbin 1) until exhaustion of such filling to a predetermined point. The engagement of the feeler and the filling will up to a certain point take place before the lay completes its forward movement, and such engagement will tend to swing the feeler and the arm f in opposite directions upon their fulcru m, and this filling-induced movement of the feeler will take place at each alternate beat of the lay until the filling has been so far exhausted that the feeler will be moved a very slight distance or not at all.

The stop b is secured to a stand or bracket 13 (shown separately in Fig. (i) and secured to the breast-beam, the stand being provided with upright walls I) b to form a guideway for the usual filling-fork slide 071, the bottom of the guideway being longitudinally slotted,

.as at If, to permit the vibration of the usual weft-ham mer VV,which is arranged, as is common, to operate at alternate beats of the lay. A lateral extension b on the bracket is separated therefrom by a guideway b, in which is longitudinally movable a sliding support or bar 0, (shown separately in Fig. 6,) having an upturned ear 0 thereon and cut away at the under side of its outer end, as at 0 the inner end of the slide being preferably enlarged laterally. The stand B is secured to the breast-beam, as herein shown, by a bolt 12, extended through a slot b in the lateral extension b of the said stand. The slide-bar c has fulcrumed upon its ear 0', as at 0 a latch-carrier 0 shown as a lever extended beyond the front and rear of its fulcrum, and at its outer end provided with a depending foot 0 to rest upon the feelerarm f when the latter is in its normal posit-ion against'the stop b said arm being supported by and sliding upon a shelf b forming a part of the stand B. A spring .9 seated in asocket c in the slidebar, (see Fig. 6,) bears upon the under side of the latch-carrier at its inner end, the action of the spring being to lift said inner end, such movement of the latch-carrierbein g prevented so long as the feeler-arm f is in normal position.

To the inner end of the latch-carrier is pivoted at 9 a depending latch o which rests against the enlarged end a of the slide-bar or support, the lower end of the latch when in its normal position (shown in Fig. 3) extending into the path of a dog or projection w of the weft-hammer W, so that when the wefthammer moves to the right or toward the front of the loom (viewing Fig. 3) it will at the critical point of its stroke engage the latch and move it and the slide-bar c bodily to the right, the outer end of the said bar at such time engaging an upturned arm d fast on the rock-shaft d, rocking the latter in the direction of the arrow 20, to thereby effect the operation of the filling-supplying mechanism, as in the patents hereinbefore referred to.

The latch-carrier is of a somewhat-peculiar shape in plan, (see Fig. 4,) the foot 0 being shown as offset from one corner thereof, and the ear 0' of the slide-bar extends up through a slot made in the latch-carrier, which latter is provided with a hub c to receive the fulcrum-stud cflprovidin g thereby firm and goodsized bearings for the parts.

In order to prevent anylifting tendency of the slide-bar, it is provided on its side, near its inner end, with a lateral lug 0 having a beveled upper face to extend under an upturned and overhanging projection 11 on the wall I), and the extension b has, as herein shown, an overlapping detent b secured to it and extended over the outerend of the slidebar 0, so that thelatter when moved outwardly by engagement of the weft-hammer and the latch will move properly in its guideway Z). The return of the slide-bar to normal position is effected by the action of the spring S through the shaft (1' and arm d inward movement of the slide being limited by the engagement of the lug c and projection or stop b hereinbefore described.

When the filling in the shuttle is sufficient in volume to swing the feeler upon its fulcrum,

the extremity of the feeler-arm f 2X will be,

swung inward or toward the lay, and thereby drawn from beneath the foot 0 of the latchcarrier, whereupon the spring .9 will lift the inner end of the carrier, raising the latch from the path of engagement of the dog 'LUX of the weft-hammer before the critical point in the stroke of the latter is reached, and no movement of the slide 0 will be effected. When the latch is lifted, the foot 0 descends between the stop b and the arm f and so prevents return of said arm against the stop, and consequently the return of the feeler to normal position is prevented until the foot 0 is lifted or withdrawn from in front of the arm f Such withdrawal of the foot is effected when the latch-carrier is returned to normal position or reset, and to efiect this operation I have herein provided the latch-carrier with a downwardly-inclined cam surface 0 (see Fig. 5) on the under side of the laterally-extended portion of the latch-carrier, such cam being in the path of and engaged by the upper extremity w of the weft-hammer as the latter moves forward or toward the breast-beam after it has passed the critical pointthat is, beyond the latch-it being understood that when withdrawal of the latch into inoperative position takes place it occurs before the wefthammer reaches it on its outward stroke; but the latch-carrier and latch will be reset afterward on the same stroke of the weft-hammer, and the arm f will engage the stop b prior to the next feeling movement of the feeler. On the return stroke of the weft-hammer the dog tu passes under and tilts the latch.

It will be manifest that no matter how rapidly the loom is running the movement of the feeler itself has no direct action upon any of the parts of the means for controlling the filling-supplying mechanism, but that, on the contrary, a comparatively slowly moving member of the loom is made the actuator for the controlling means, such means including the latch and its sliding support, the arm (i and rock-shaft cl, and from the foregoing it will also be manifest that the feeler is not permitted to return to normal position until there is no possibility of the controlling means being actuated at that time. Any effects due to the momentum of the layare entirely eliminated, and the feeling mechanism,which must necessarily be to a certain extent delicate in its construction, is relieved from all sudden shocks and strains due to such momentum action. When the weft-hammer engages the latch an d moves the slide-bar toward the front of the loom, the latch travels in the space be- IIO tween the narrow shelf 5 and the upright wall 1) of the stand B, and after such action the spring S operates through the rock-shaft d and arm (1 to move the slide-bar back to its normal position, the next outward stroke of the weft-hammer operating to lift the foot 0 of the latch-carrier upon the arm f then in its'normal position, against the stop b Owing to length of the feeler-arm fand to the adjustability of the feeler support or fulcrum a very delicate and fine ajustment of the parts can be effected, so that the operation of the filling-supplying mechanism can be timed to a nicety, and in practice it is only necessary to leave enough filling on the fillin g-carrier to extend once across the lay after the predetermined point of exhaustion has been reachedthat is, the amplitude of movement of the feeler will gradually decrease from the first filling-induced movement of the feeler until the movement of the feeler is so slight that the arm f will not be withdrawn from operative position relative to the latchcarrier.

Aknoek-oif lever 'n n for the shipper-lever N is fulcru med on the breast-beam at a, (see Fig. 1,) the end of the lever-arm n being bent over, as at it in front of the outer end of the usual weft or filling fork slide m, longitudinally slotted at m (see Fig. 4) for the upper end of the weft-hammer and provided with a filling-fork m pivoted at m and pro vided with the usual tail m to be engaged by the hook on, pivotally connected with the upper end of the weft-hammer when the hook is not tilted, owing to the failure of the filling. Should the filling break, therefore, or he accidentally exhausted, the outward movement of the weft-hammer will operate through the hook m and the tail of the fork to move the slide m out and into engagement with the end a of the knock-off lever, moving the same against a suitable spring .9 to release the shipper-handle from its holding-notch, and through suitable belt-shipping devices (not shown) the loom will be stopped. The end of the arm n is notched, as at m Fig. 1, to embrace an upturned arm dflloosely mounted on the rock-shaft d and having a downturned end (1 (partially shown in Figs. 2 and 3) to effect disengagement of the take-up pawl and ratchet when the loom is stopped. lhus the apparatus herein shown and described will operate to automatically efieet a change of filling when the filling in the shuttle has been exhausted to a predetermined extent, and the loom will be automatically stopped upon failure of the filling due to breakage.

The mechanisms controlled respectively by the amount of filling in the shuttle and by the presence or absence of filling are operated by a common actuator-viz. the weft-hammeras herein shown and described.

The relative lengths of the feeler and feelerarm f make it possible for a very slight movement of the feeler to eifeet a proportionally-large movement of the free end of the arm f providing thereby for a much closer action of the feeler and the filling-supplying mechanism controlled thereby than has been heretofore possible.

My invention is not restricted to the precise details of construction and arrangement herein shown and described, as the same may be modified or rearranged in various particulars without departing from the'spirit and scope of my invention.
