Specification of Letters Patent,

Batenteoi Maren 20, 19i16.

'Applieationfiledduly 31,1995. ,SerialNo. 271.925 t Be a knownthat I, OMAR BESSON; a he: zen of the United States, and a resident of New Bedford, county of Bristol, State of Massachusetts, have invented an Improve ment in Thread Parting Mechanism for Looms, of which the following description, in connection with the accompanying drawings,

is a specification, like characters on the drawin s representing like parts.

n automaticfeeleialooms, wherein the, running filling is automatically replenished rior to complete exhaustion, means have een devised 'to sever the old filling end close to the shuttle at the time filling re lenish ment is effected and also to sever sue filling:

end adjacent the edge of the cloth. This latter severance is usually effected by a severing device on the temple, a number of different forms of successful thread-cutting temples being in practical use at the present time.

The severing or-parting near the shuttle'is most conveniently effected bv a dparting detion to act upon and sever the old filling A device of this character is shown in 5o ically vice mounted on the shuttlefee r, the full movement of the latter when the shuttle is roperly boxedat the replenishing side of the 00m carrying the parting device into poscilen r v nited States Patent to Draper,'No. 683,423, dated September 24, 1901, to which reference may be had. Inasmuch as the old filling end extends from the edge of the cloth tothe shuttle-eye at the time the parting device acts, sometimes it will slacken sufiiciently to drop below the parting device, "so that the latter fails 'to act, and the filling end-is then apt to give trouble, either by catching and tangling with the new filling or by snapping back and getting into the cloth. I

My present invention refates to threade parting mechanism of the character specified; and it has for its particular object the production of simple and-effective means for in- 'suring the proper cooperation of the old filling end with the device designed to partner sever it near the shuttle. I

I have shown my invention as applied to a loom provided with mechanism for auto'mat fresh fi ing at the r(}per time and in connection with a shutt ee elerp arting device of providing the running shuttle with the character shown and described'in the patent hereinbefore referred to; but I desire it to'be understood, that my invention is not thereby restricted in its application merely 1 to the two particular mechanisms sh own.

Figure 1 1s a transverse sectional'vie'w-of a 4 ortion of a loom provided with automatic Hing-replenishing mechanism and a shuttle-f feeler-parting device with one embodiment of my invention applied thereto, the apparatus being shown in normal'position; an ig. 2 is an opposite side elevation of the upper end of the shuttle-feelerin operative position and with the filling-positioning device thereon, the dotted-line position of said device showing the manner in which it operates.

' The lay A ,the filling feeder or hop er F, Fig. '1, to hold the reserve filling-supp ies b,- the transferrer f, having a depending endf ,the controlling rock-shaft (1', having an at arm m on the transferrer end having a lat eral lug m", the notched dog m on said arm, and the hunter 0 on the layto engage the dog and operate the replenishing mechanism tached arm (Z held down by the spring S the may be and are all of well-known construction and operation.

The upturned arm bent'rearwardly at its upper end at Y to constitute a shuttle-feeler and notched at 3,

Y, fulcrumed at a and 3 the stud y on the arm Y and provided with a finger n to rest upon the lug m as shown in Fig. 1, and the parting devicemounted on the feeler and comprising the fixed and moy; V able blades 0 e and the means for operating the same may be and are all substantially as' in Patent No. 683,42 3, referred to.

When the feeler is moved into operative position (see Fig. 2) adjacent theinner end of the re ,lenishin shuttlebox,the old filling end shou d enter t e notch 3 and between the blades of the parting instrumentality to be severed when said blades are closed. If the fillingend is slack, it tends to sa below the notch, and hence sometimes will notbeso positioned ,that the parting device can cooperate witih it and -part it. To overcome this fault, have provided means to insure operative positioning of'the fillin end, even if the same be slack or sags. As est shown in Fig, 2;, I have mounted on a pin orstud 1 projecting from the outer side of the feeler, a

of the partin movement of t rock-shaft d, and removing finger lifts it so that cated below and eratively ppsitioned and the lay heats up, and

secured to or forming a part of the finger adjacent its fulcrum 1 I have provided an up-' turned and rearwardly-extended branch or actuatorj t, terminating in a cam-face 5. A forward extension 6 on the finger is normally adapted ,to rest a ainst a nut 7 on a portion device to limit downward I e fingerand actuator, a spring 8 acting to retain said parts in full line or normal position with relation to the feeler.

The feeler is moved into operative position prior to change of filling by rocking of the thereby elevating the arm d the pressure on the pin 30 on arm Y, so that the arm at can swing the dbg m up into the hunter-path and at the same time act through finger n to position the feeler." The feeler and the parting instrumentality being in operative position, the la r beats up, and a part on the lay, as the bacir wall 9 of the replenishing shuttle-box, engages the cam-face 5 and swings the actuator 4 upward. This causes the finger '7, which has passed under the old filling end, to rise, and if the filling end is sagging the rise of the it is bound to enter the notch 3 and be positioned to be parted when the parting-blades c and 0 are closed. Preferably a transverse groove, as 10, Fig. 2, is made in the lay to receive the finger 2, so that the latter passes below the raceway on the lay before it is lifted by the actuator. When the lay swings back, the actuator4 and finger 2 swing down on the fulcrum 1 to normal position relatively to the feeler, and the latter is swung fen ard to normal inoperative position, as is usual, the filling-replenishing mechanism having been operated to replenish the filling. Thus the old filling end is necessarily parted at the proper time and place, as its position for cooperation with the parting instrumentality is insured by the means described.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom provided with filling-replenishing mechanism, a shuttle-ieeler having a notch in its end, a device on the feelcr to part the old filling end when the latter, enters the notch, and means to insure the entrance of such filling end into the notch in position to I be acted upon by the parting device.

2. In an automatic filling re lenishing loom, an instrumcntality to part t 1e old filling end,and means to-automatically insure the positioning of the filling end to be acted upon by said instrumentality.

In an automatic filling replenishing loom,a shuttle-feeler movable into operative position prior to filling "change, a device mounted on the feeler and movable therewith into'position to act upon and part the old filling end, and means also mounted on the feeler to engage and automatically position the filling end to insure action thereupon by the parting device.

a. In an automatic filling replenishing loom, a shuttle-feeler movable into operative position prior to filling change, a device mounted on the feele r and movable.therowith into position to act upon and art the old filling end, and means to exten under and lift the filling end into proper position to be acted upon by the parting device.

5. In an automatic filling-replenishing loom, a shuttle' -feeler movable into operative position prior to filling change, a device mounted on the feeler and movable therewith into position to act upon and part the old filling end, feeler and adapted to extend under the filling end, and means to swing the finger upward to lift the filling end into position to insure action thereon by the arting device.

6. In a loom provi ed with mechanism to automatically replenish the running filling prior to complete exhaustion thereof, a shuttle-feeler, a parting device to (part the old filling end near theshuttle, an an automatically-operated finger on the feeler to pass under and lift the filling end and thereby insure the cooperation therewith of the parting de- V100.

7. In a loom provided with automatic filling-replenishing mechanism, a shuttle-feelcr, an instrumentality bodily movable therewith into position to part the old filling end upon filling replenishment, a positioning-finger to engage and lift the filling end into position to be parted, and an actuator for the finger operated by engagement with 8. In an automatic filling-replenishing loom, an instrumentalit i bodily movable upon replenishment of filling into position to act upon and part the old filling end near the shuttle, and means to automatically insure the positioning of the filling end tobe acted upon by'said instrumentality.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
