Definitions
- the present invention relates to thread cutting temples for looms.
- the usual filling replenishing loom whether of the bobbin changing or shuttle changing type, requires a thread cutting mechanism to be mounted close to the selvage, to trim oi? the ends of filling that would otherwise be left hanging from the cloth as an incident to the replenishing operation.
- Such thread cutting mechanism is usually mounted in the temple on the replenishing side of the loom.
- the temple thread cutting mechanism operates continuously, regardless of whether or not there are threads in position to be cut,'-although some such mechanisms are designed to take into consideration the fact that there are no threads to be out except immediately after filling replenishment, and accordingly they only operate a few times immediately after each replenishing operation.
- a further object is to provide an improved timing device for rendering the thread cutting mechanism inoperative after a predetermined number of operations.
- Fig. 1 is a side elevation of the head of a temple embodying my invention
- Fig. 2 is a cross-section, taken substantially on line 2-2 of Fig. 1 but with the thread cutting blades and certain other parts not shown in section.
- Fig. 3 is a view similar to Fig. 1 but with certain parts omitted or shown in dotted outline, and other parts in different operative relation, as suggested by line 3---3, Fig. 2; and
- Fig. 4 is a similar view, except that parts below line 4H4, Fig. 2 are omitted and the remaining parts occupy still a different operative relation.
- the temple 1, which includes the usual temple head 2, may be mounted on the loom in any conventional manner, not requiring further mention.
- the thread cutting mechanism is, as above intimated, mounted in the temple head, and preferably is comprised of a stationary ledger blade 3 and a movable cutter blade 4 positioned side by side in a guide way 5 extending from front to rear through the temple head.
- the ledger blade 3 may conveniently be of the form shown in my co-pending application S. N. 625,763, filed July 29, 1932.
- the movable cutter blade 4 consists simply of a flat piece of metal, cast or otherwise formed, and having at its rearward end a depending cutting tip 6, the sharpened cutting edge of which cooperates with a vertical edge 7 formed on the ledger blade.
- the guideway 5 is suihciently narrow to confine the movable cutter blade 4 to movements in. a vertical plane.
- the blade 4 is adapted to both rock and slide in the guideway, but the forward end of the blade is confined against vertical movement while the rearward end is free to move vertically as well as horizontally. Accordingly, the forward end of the guideway is restricted in height, as by two pins 8 formed on or secured to the temple head.
- I For operating the movable cutter blade, I provide an oscillating member constituted by a short stud 9 bearing directly in the temple head.
- the stud may be provided with an eccentric portion, as pin 10, engaging in a hole in the cutter blade 4, for operating the latter. Since the stud 9 is transverse to the plane of movement of the movable cutter blade, and eccentric pin 10 engages this blade intermediate its ends, oscillation of the stud will serve to rock and slide the cutter blade.
- the pin 10 occupies a position horizontally rearwardly of the axis of the stud 9. From this position the stud oscillates clockwise, till the pin is down (see Fig. 3).
- Movement of the stud through approximately 90 degrees will serve to lower the rearward end of the cutting blade, thus hooking the cutting tip behind the filling, and move the blade 4 for wardly to cut the filling thread.
- the blade 4 is returned to normal position by rotating the stud in the other direction.
- the stud 9 is oscillated, preferably by means including an arm 11 fixed thereto.
- the stud 9 is provided with an enlarged portion 12 and a reduced portion 13, for a purpose subsequently to be described.
- the extreme end of the stud is still further reduced, at 14, and the arm 11 is provided with an opening fitting over this end 14, the arm bearing flat against the end of portion 13.
- a pin 15 in the arm engages a hole 16 in the end of portion 13, thus constraining the arm and stud to move together.
- a screw 1'7 having an enlarged head, is threaded into the end of the stud the head holding the arm 11 in place.
- the arm 11 is moved in one direction, i. e., clockwise in Fig. 1, by being struck by the lay or a hunter thereon (not shown).
- a spring 18 is provided for moving the arm in the other direction.
- the spring has one end looped to engage a pin 19 in arm 11 and, after making several complete turns about the stud, has its other end engaged about a pin 20 in the face of cover plate 21.
- the cover plate 21 is held in place by screws 22 passing therethrough and threaded into the temple head.
- An opening is provided in the cover plate, of sufficient size to admit portion 13 of the stud but too small to permit passage therethrough of the enlarged portion 12, and by this means, the stud and arm are held in place in the temple head.
- the thread cutting mechanism thus far described may be used with or without the timing device described presently. In either event, it is susceptible of modification, within the scope of the appended claims. However, the principle involved is particularly desirable in that it will afford a positive control over the path of movement of the cutting tip.
- timing device with this type of thread cutting mechanism
- the particular form thereof shown. is peculiarly susceptible to such use. Accordingly, I have devised, and shown, a simple, efficient timing device for locking arm 11 out of operation after a predetermined number of operations thereof.
- a ring 23, slightly larger, internally, than enlarged portion 12 of stud 9, is rotatably supported in the temple head in such manner as to be concentric with the stud.
- the periphery of the ring is provided with a number of small, equally spaced notches 24, and at least one deeper recess 25.
- the inner periphery of the ring is provided with notches 26 spaced, angularly, the same as the notches 24, although not necessarily aligned therewith.
- the enlarged portion 12 of the stud is cut out to form a shoulder 27, a wall 28 formed on an arc concentric with the axis of the stud, a pocket 29 and a shoulder 30.
- a ball or roller 31 is positioned within this cut out space.
- the arm 11 is provided with an extension 34 which is engaged by the nose 32 when the latter drops into the recess 25.
- the cutting mechanism may be returned to operation at time of filling replenishment, by means of a finger 35 which may be associated with the replenishing mechanism in such a manner as to be raised and held in raised position for one or two picks each time the replenishing operation takes place.
- a finger 35 which may be associated with the replenishing mechanism in such a manner as to be raised and held in raised position for one or two picks each time the replenishing operation takes place.
- Each time finger 35 is raised, and thereby latch 33 the cutting mechanism operates a predetermined number of times and then is again locked out of operation as above described.
- timing device herein disclosed is particularly adapted for use with the type of thread cutting mechanism shown, it may, nevertheless, be used with other than this particular cutting mechanism. Also, the timing device itself is susceptible of change, within the scope of the appended claims.

14 Claims.
The present invention relates to thread cutting temples for looms.
The usual filling replenishing loom, whether of the bobbin changing or shuttle changing type, requires a thread cutting mechanism to be mounted close to the selvage, to trim oi? the ends of filling that would otherwise be left hanging from the cloth as an incident to the replenishing operation. Such thread cutting mechanism is usually mounted in the temple on the replenishing side of the loom. Generally speaking, the temple thread cutting mechanism operates continuously, regardless of whether or not there are threads in position to be cut,'-although some such mechanisms are designed to take into consideration the fact that there are no threads to be out except immediately after filling replenishment, and accordingly they only operate a few times immediately after each replenishing operation.
It is an object of my invention to provide an improved form of temple thread cutting mechamsm.
A further object is to provide an improved timing device for rendering the thread cutting mechanism inoperative after a predetermined number of operations. 7
Further objects will, in part, be hereinafter more specifically enumerated or will become obvious as the description proceeds.
The preferred embodiment of my invention is illustrated on the accompanying drawings, in which:
Fig. 1 is a side elevation of the head of a temple embodying my invention;
Fig. 2 is a cross-section, taken substantially on line 2-2 of Fig. 1 but with the thread cutting blades and certain other parts not shown in section.
Fig. 3 is a view similar to Fig. 1 but with certain parts omitted or shown in dotted outline, and other parts in different operative relation, as suggested by line 3---3, Fig. 2; and
Fig. 4 is a similar view, except that parts below line 4H4, Fig. 2 are omitted and the remaining parts occupy still a different operative relation.
The temple 1, which includes the usual temple head 2, may be mounted on the loom in any conventional manner, not requiring further mention.
The thread cutting mechanism is, as above intimated, mounted in the temple head, and preferably is comprised of a stationary ledger blade 3 and a movable cutter blade 4 positioned side by side in a guide way 5 extending from front to rear through the temple head.
The ledger blade 3 may conveniently be of the form shown in my co-pending application S. N. 625,763, filed July 29, 1932. The movable cutter blade 4 consists simply of a flat piece of metal, cast or otherwise formed, and having at its rearward end a depending cutting tip 6, the sharpened cutting edge of which cooperates with a vertical edge 7 formed on the ledger blade.
The guideway 5 is suihciently narrow to confine the movable cutter blade 4 to movements in. a vertical plane. The blade 4 is adapted to both rock and slide in the guideway, but the forward end of the blade is confined against vertical movement while the rearward end is free to move vertically as well as horizontally. Accordingly, the forward end of the guideway is restricted in height, as by two pins 8 formed on or secured to the temple head.
For operating the movable cutter blade, I provide an oscillating member constituted by a short stud 9 bearing directly in the temple head. The stud may be provided with an eccentric portion, as pin 10, engaging in a hole in the cutter blade 4, for operating the latter. Since the stud 9 is transverse to the plane of movement of the movable cutter blade, and eccentric pin 10 engages this blade intermediate its ends, oscillation of the stud will serve to rock and slide the cutter blade. When the cutting tip is up and projected rearwardly, as in Fig. 1, the pin 10 occupies a position horizontally rearwardly of the axis of the stud 9. From this position the stud oscillates clockwise, till the pin is down (see Fig. 3). Movement of the stud through approximately 90 degrees will serve to lower the rearward end of the cutting blade, thus hooking the cutting tip behind the filling, and move the blade 4 for wardly to cut the filling thread. Conveniently, the blade 4 is returned to normal position by rotating the stud in the other direction.
The stud 9 is oscillated, preferably by means including an arm 11 fixed thereto. In the present instance, the stud 9 is provided with an enlarged portion 12 and a reduced portion 13, for a purpose subsequently to be described. The extreme end of the stud is still further reduced, at 14, and the arm 11 is provided with an opening fitting over this end 14, the arm bearing flat against the end of portion 13. A pin 15 in the arm engages a hole 16 in the end of portion 13, thus constraining the arm and stud to move together. A screw 1'7, having an enlarged head, is threaded into the end of the stud the head holding the arm 11 in place.
The arm 11 is moved in one direction, i. e., clockwise in Fig. 1, by being struck by the lay or a hunter thereon (not shown). A spring 18 is provided for moving the arm in the other direction. The spring has one end looped to engage a pin 19 in arm 11 and, after making several complete turns about the stud, has its other end engaged about a pin 20 in the face of cover plate 21.
The cover plate 21 is held in place by screws 22 passing therethrough and threaded into the temple head. An opening is provided in the cover plate, of sufficient size to admit portion 13 of the stud but too small to permit passage therethrough of the enlarged portion 12, and by this means, the stud and arm are held in place in the temple head.
The thread cutting mechanism thus far described may be used with or without the timing device described presently. In either event, it is susceptible of modification, within the scope of the appended claims. However, the principle involved is particularly desirable in that it will afford a positive control over the path of movement of the cutting tip.
While, as stated, some aspects of my invention do not require the use of a timing device with this type of thread cutting mechanism, the particular form thereof shown. is peculiarly susceptible to such use. Accordingly, I have devised, and shown, a simple, efficient timing device for locking arm 11 out of operation after a predetermined number of operations thereof.
In the particular embodiment shown, a ring 23, slightly larger, internally, than enlarged portion 12 of stud 9, is rotatably supported in the temple head in such manner as to be concentric with the stud. The periphery of the ring is provided with a number of small, equally spaced notches 24, and at least one deeper recess 25. The inner periphery of the ring is provided with notches 26 spaced, angularly, the same as the notches 24, although not necessarily aligned therewith. The enlarged portion 12 of the stud is cut out to form a shoulder 27, a wall 28 formed on an arc concentric with the axis of the stud, a pocket 29 and a shoulder 30. A ball or roller 31 is positioned within this cut out space. The parts of the timer thus far described constitute a form of one way clutch, whereby oscillation of the stud 9 serves to rotate the ring 23 in one direction only (clockwise, Figs. 1, 3 and 4).
p The manner of operation of the one way clutch will be described briefly. Starting with the parts positioned as in Fig. 4, at which time arm 11 is rearward as in Fig. 1, forward movement of the arm a few degrees will rotate stud 9 clockwise without disturbing the ball 31 or ring 23 until shoulder 27 engages the ball. The distance from wall 23 to the bottom of a contiguous notch 26,
measured along a radius of the stud, is but a few thousandths of an inch greater than the diameter of the ball, and, in this latter position, the wall keeps the ball in its notch. Continued movement of the arm and stud result in the stud, ball and ring moving together an angular distance corresponding to the spacing between notches 24, where the ring is held by a nose 32 formed on spring pressed latch 33. As the arm and stud move in the other direction (counterclockwise) shoulder 29 rolls the ball out of its present notch 26 into the next one, ring 23 remaining stationary. This operation is then repeated, until recess comes under the nose 32, when the nose drops down into the recess.
The arm 11 is provided with an extension 34 which is engaged by the nose 32 when the latter drops into the recess 25. By this means, the arm, and the thread cutting mechanism, are locked out of operation. The cutting mechanism may be returned to operation at time of filling replenishment, by means of a finger 35 which may be associated with the replenishing mechanism in such a manner as to be raised and held in raised position for one or two picks each time the replenishing operation takes place. Each time finger 35 is raised, and thereby latch 33, the cutting mechanism operates a predetermined number of times and then is again locked out of operation as above described.
It is to be noted that while the timing device herein disclosed is particularly adapted for use with the type of thread cutting mechanism shown, it may, nevertheless, be used with other than this particular cutting mechanism. Also, the timing device itself is susceptible of change, within the scope of the appended claims.
