ration of Maine "Application March 19 8 Claims.

The present invention relates to loom temples and has more particular reference to temples which are provided with filling parting means for use on automatic filling replenishing looms.

vIn looms of the type mentioned, the filling replenishing operation leaves filling ends projecting from the selvage of the cloth, and the temple is provided with parting mechanism for trimming these filling ends adjacent the selvage. The actual parting, means may be of different forms but preferably includes a movable cutting blade for cutting the filling. It is to means for actuating the parting means, as a cutting blade, that my invention pertains.

Prior to my invention, filling parting means of the class described usually included a rocking and sliding cutting blade having a depending heel adapted to be struck by the lay. This, and

other types of parting means, are subject to the disadvantage that they wear out rapidly, and thus require considerable attention. Furthermore, they must be constructed and adjusted with a high degree of accuracy, which detracts from their commercial value.

I propose to provide a filling parting means, and operating means therefor, which shall not be subjected to repeated heavy blows by the lay and which accordingly shall not be subject tov excessive Wear. I further propose to so design such parting and operating means as to dispense with any necessity for extreme.accuracy in construction or adjustment.

To the end mentioned, I have devised, and herein disclose, a reciprocating temple provided with a movable cutting blade operated by inertia-activated means which is'rendered eifecti-ve by reciprocation of the'temple. Preferably, the operating means consists of a weighted element on the temple in such manner as to tend to remain stationary, solely through its own inertia, -while the temple reciprocates. The inertia-induced relative movement between the weighted element and the temple may be utilized in a variety of ways to operate the movable cutting blade.

The accompanying drawings illustrate three preferred embodiments of my invention. Refer-' ring to the drawings:

Fig. 5 is a view similar to Fig. 4 but showing 1 a second embodiment; and

Fig. 6 shows a still further embodiment of the invention.

The loom to which my invention has been applied is conventional in design and accordingly I have illustrated. only the breast beam 1 and the reciprocating lay 2. The breast beam ex-. tends across the front of the loom in the usual manner and the lay reciprocates forwardly and rearwardly, toward and from the breast beam. The 'warp threads W are woven with filling to form cloth C which feeds toward the front of the loom. a

Referring to Figs. 1-4, a slide 3 is mounted on the breast beam to support a temple housing 4. A temple bar 5 is slidably mounted in the housing 4 forreciprccation forwardly and rearward ly of the loom. The temple is yieldingly, urged rearwardly by a coiled spring 6 within the housing and is moved forwardly when a depending heel 7 onthe bar is struck by the lay; A laterally extending temple head 8 may contain the usual temple rolls 9 journalled on a roll pin 10. The temple and temple head are of usual. construction except as modified to accommodate the present filling parting means and its operating means. The temple head 8 is provided with a recess or cavity of a shape shownon the drawings, to receive the filling parting means and the aforementioned operating means. In the embodiment illustrated by Figs. 1-4 a ledger blade 11 is secured to one vertical wall of the cavity as by screws 12, 12. The rear, vertical edge of the ledger'blade is notched at 13. to receive and support the filling f which extends from the cloth selvage. The lower edge 14 of the notch 13 may be left blunt,to serve merely as a support for the filling or may be sharpened, to assist in the cutting thereof.

The movable cutting blade 15 is carried by a hub 15 (Fig. 4) which is loose on the roll pin 10. The cutting blade 15 oscillates freely about the axis of the rollpin and. is not subjected to any heavy stresses. Consequently, this blade can be made of thin steel and provided with a very sharp cutting edge. T

In the embodiment under discussion the operating means for the movable cutting blade is comprised simply of a weighted element 17 formed integral with the hub 16-and projecting upwardly and forwardly therefrom. A stop screw 18 engages the element 17 to limit counterclockwise movement thereof. The weighted element is comprised of a fairly heavy mass of metal positioned so that its center of gravity is well above the axis of the roll pin 10.

The force of gravity holds the weighted element and the movable cutting blade in the position shown at all times except during the period or reciprocation of the temple. When the lay strikes the temple heel and the temple is suddenly moved forwardly the inertia of the element 17 causes the latter to tend to remain stationary. Since the element is pivoted to the roll pin it cannot remain stationary, but will move clockwise relative to the temple, about the roll pin. Thus, when the templeheel is struck by the lay the movable cutting blade is moved down onto any filling which is positioned in the notch 13 and such filling will be severed. Return of the temple rearwardly by the spring 6 results in the cutting blade and weighted element being restored to normal position.

It will be apparent that'neither the inertiaactivated element 1'7 nor, the movable cutting blade is subjected to any great strain, wherefore the likelihood of their becoming worn out or broken is very small.

It will likewise be apparent that other inertiaactivated means may be utilized in different manners to operate a filling parting device. Two of such other means will now be described.

Referring first to Fig. 5, the temple bar 19, temple head 20, heel 21, roll 22 and roll pin 23 are similar to those above described except that the cavity in the temple head is modified as will be apparent. Only a short ledger blade 24 is used, and the movable cutting blade 25 is formed integral with the hub which is journalled on the roll pin inwardly of the roll pin support 26. Extending forwardly from the hub of the cutting blade is an arm 27 which contacts the weighted element 28. The element 28 is pivotally suspended from a pin 29 in the temple head.

The arm 27 is sufiiciently heavy to overbalance the blade 25 and thus remain in contact with the weighted element. It is thought that the manner in which the inertia of the weighted element causes relative movement between the latter and the temple and the manner in which such relative movement is caused, by the connection 27, to operate the cutting blade will be obvious.

Referring to Fig. 6, the temple bar 30, head 31, and other parts including the roll pin 32, ledger blade 33, cutter blade 34 and arm 35 are identical with corresponding parts in Fig. 5. The inertiaactivated element 36 is'in the form of a block which is slotted at 37 to receive a pin 38 in the temple head. The block is slidably supported by the pin and by a ledge 39 on the temple head. An upwardly and forwardly inclined cam surface 40 on. the block is engaged by the connecting arm 35.. A light coiled spring 41 is positioned between the temple head and the block to prevent the latter from jarring forwardly from the vibration of the loom. This spring does not operative- 1y modify the operation of the block, but only prevents it from becoming misplaced.

The mode of operation of the device of Fig. 6 is obvious and requires no further discussion.

Having fully disclosed preferred embodiments of my invention, I claim:
