Figure 14a is a similar view showing the needle ciprocatory needle bar ll having a needle l3,

clamped therein, to move therewith, at all times, during the sewing operation of the machine. This needle has the usual eye at its'lower pointed end for receiving the tufting yarn or thread i1, passed through a guide l3, through a tension device 'i 3, over stationary guide pins 23 and 2|. through the eye 22 of a slack producing ierker, the eye 23 of a yarn pulling device, and through the eye of the needle. Attention is called to the fact that the eye 22 is arranged between the tension device l3 and the needle. The yarn also passes through a slack producing device or Jerker, including an inverted U-shaped bracket 24, rigidly secured to the arm l2, and having apertures 23 through which the yarn slidably passes. The yarn is fed from the usual cone spool (not shown) and which is ordinarily not supported upon the head. Engaging beneath the yarn within the bracket 24 is a horizontal head 23, carried by a reciprocatory rod 21 guided in an aperture formed in the top of the arm i2, and operated by means to be described. When the head 23 rises, it travels above the apertures 23, and thereby pulls the yarn from the spool, and provides a slack when the rod 21 descends. The purpose of the head 26 and associated elements is to maintain a constant slack in the yarn fed from the spool, so that the tension of the tension device I3 is not varied by any resistance that the spool might offer. The needle bar also carries an eye 23 at its lower end. The eye 23 is at substantially the same elevation as the eye 23,when the needlebaris raised. 7

The machine embodies the usual drive shaft 23, suitably Journaled in the arm l2, and horizontally arranged, ,as shown. and driven by a grooved pulley 33, which may be manually or power driven.

At its forward end the drive shaft 23 is provided with a crank disc 3i rigidly secured thereto, and having pivotalconnection with a link 32. This link is pivotally connected with a sleeve 33. The sleeve 33 is a part of the original sewing machine. This sleeve is ordinarily clamped to the needle bar, to reciprocate therewith, by means of a set screw. In accordance with the present invention, this set screw is removed and the sleeve 33 is therefore slidably mounted upon the needle bar II. The sleeve is capable of raising the needle bar, but the needle bar may beheld in the raised position when the sleeve 33 is lowered, as will be explained. Arranged above the sleeve 33 is a block 7 34, rigidly clamped to the needle bar by a set screw 33. Rigidly' secured to the block 34 and preferably formed integral therewith is a horizontal arm 33, included in the yarn jerking device and carrying .the aperture 22. The block 34 is engaged by a compressible coil spring 31, surrounding the needle bar i3, and also engaging the end wall 33 of the head II, as shown. The spring 31 serves to move the needle bar downwardly while the sleeve 1 33 serves to raise the needle bar, but the, needle bar is permanently slidable within the sleeve 33.

The machine further comprises a presser foot 33, of the usual construction, clamped to a reoperator, including work feed dogs 43, operating 1 through a suitable opening in the base or through the throat plate, as is well known. These feed dogs are rigidly mounted upon a rigid dog supporting bar or link 43. At one end, this bar or link is rigidly connected with a transverse head 41, pivoted at 43, with cranks 43, in turn rigidly mounted upon the rock shaft 43. At its opposite end, the rigid bar or link 43 is provided with a fork 33, receiving a roller 5|, pivotally mounted upon a crank 52, in turn rigidly mounted upon the rock shaft 44. The rock shafts therefore constitute the operating means for the work feed mechanism. These rock shafts extend longitudinally of the driveshaft 23 and are parallel therewith. The rock shafts 43 and 44 are provided ad- :Iacent to the stock Ii with cranks 33 and 34 respectively. The cranks 33 and 54 are pivotally connected with connecting rods 55 and 33 respectively, which are actuated by cams 31 and 33 respectively, in turn carried and driven by the drive shaft 23. It might be stated at this point that the rock shaft 43 serves to move the dog carrying bar or link 46 longitudinally, while the rock shaft 44 serves to raise and lower the same. The drive shaft 23 is also provided with a crank 33, in-,

' eluding a crank pin 33. The foregoing description is that of the ordinary Singer sewing machine, with the exception that the needle bar is I reciprocated in a different manner, as explained.

Rigidly attached to the base l4 adjacent to one longitudinal edge thereof and depending from said such base are brackets 3i, having bearings for holding an auxiliary rockshaft 32, arranged near and parallel with the rock shaft 43. vThis auxiliary rock shaft carries a long crank arm 33, equipped with a collar 34, adapted to be clamped to the rock shaft 32 by a set screw 63 or the like. Pivotally connected with the crank arm 33, at 34, is a connecting rod or link 61, the upper end of which is pivotally connected with the crank pin 33, as shown. The reciprocatory rod 21 is pivotally connected with the crank arm 63 at 33.

We provide a looper, gripper, cutter and loop shifting arm which are removable as a unit. This unit comprises a block 33, adjustably mounted in a groove 13, formed in a stationary lug 1i, arranged beneath the bed l4. This lug is provided with a depending screw threaded stud 12, rigidly secured thereto. This stud passes through an elongated opening I3, formed in the block 83, and is engaged by a removable nut 14, equipped with a handle 15 for convenient turning. when the proper position of the block 63 is found, an justing bolt 13 is screwed up until it lightly contacts with the stud l2 and the bolt 13 may then be locked in place by the lock nut TI. The bolt It does not interfere with the removal of the block 33 from the stud l2. RigidLv attached to one end of the block 33 is a horizontal shaft 13, having a reduced screw threaded end 13. Pivotally mounted on this shaft is a sleeve 33, engaging between shoulder 3| and washer 32, held in place by nuts 33, having screw threaded engage- This arm has an opening 86 to receive a bolt 81 passing through an opening 08 in a second arm 89, and carrying a nut 90. The arm 89 may be angularly adjusted with respect to the arm 04 and locked thereto in the selected adjusted position. The arm .94 carries a shaft 9|, rigidly secured thereto, and this shaft has a slot 92 to receive the end of a coil 92 formed upon a resilient gripper element 94. The arm 84 of the gripper is provided with a depending crank 95, carrying a stud 90, which is readily removable from within the aperture 91 formed in a link 99, which is pivotaliy connected with a depending crank 99,rigid1y mounted upon the auxiliary rock shaft 92. Arranged upon and near one side of the gripper, is a looper member including an arm I00, having an opening IN to receive the sleeve 80. The arm III has the looper element I02 rigidly attached to its upper end, by means of screws I09 and a plate I94, and the looper element is preferably detachable from the arm I00. The resilient gripper element 94 is arranged upon the same side of the looper element I02 with the needle. A washer I is arranged between the arms 94 and I00, and a nut I09 has screw threaded engagement with the sleeve 90, and serves to clamp the arm I00 and the arm 04 together. The arm I00 may be angularly adjusted with respect to the arm 94, and when the nut I94 clamps the arm I00 to the arm 94, the gripper and looper swing as a unit. Since the gripper is swung by the link 98 and associated elements It will be seen that the looper is swung by the gripper, and the gripper and looper swung in unison, but this swinging movement does not cause the resilient gripping element 94 to be shifted into engagement with the looper element I02. The numeral I09 designates a blade or cutter, having an inclined cutting edge I04, to coact with the looper element I02, and sever all loop or loops thereon, and for this reason the looper element I02 need not have a down turned or hooked end. The blade or cutter I03 is pivoted upon the looper element I02 by means of a bolt I05 engaging within an opening I09 and this bolt also passes through a bowed leaf spring I01, which serves to retain the blade or cutter I03 in firm engagement with the ad- Jacent face of the looper element. The blade or cutter has a depending crank Ill carrying a stud I09, which is readily removable from within an aperture IIO,-formed in a link III, pivoted at II2, with 9. depending crank III, rigidly secured to the rock shaft 43. The pin or pivot H2 is continuously moving or rocking during the operation of the machine, and causes the cutter or blade I03 to turn upon its pivot and have a shearing action with the looper element I02 to shear all loops upon the looper element. Rigidly attached to one side of the. block 69 is a small block I", having a horizontal opening I I5, to receive a rock shaft IIB, having a crank II'I rigidly secured to one end thereof. This crank has an aperture I I9 to readily removably receive the transverse end of a link II9, pivotally connected with a .crank I20, mounted upon the auxiliary rock shaft 62. The opposite end of the rock shaft H8 is provided with a head I2I rigidly secured thereto and having an opening I22, receiving the end I23 of a loop shifting finger I24. The end I2! is clamped within the opening I22 by a set screw I25. Thearm I24 is generally U-shaped, and extends below and about the gripper and looper and has its upper end bent laterally toward the looper element I02 to provide a portion I29, which travels near and above the looper element and projects over the same, to engage that side of the loop next to the cutter. It might be stated that the loop shifting arm or element is not employed to transfer loops from the needle to the looper, and this finger is not thrown into action until after the looper element has moved toward the needle and entered the loop and has started upon its movement from the needle. 7 The function of the loop shifting arm I24 is to shift that side of the loop next to the cutter further rearwardly upon the looper element, upon the starting of a new group of loops and when that side of the loop next to the cutter has been pulled from the fabric. Ordinarily this leaves that side of the loop next to the cutter in the form of a short portion, which should be severed, and this short portion sometimes moves from between the looper element and cutter or blade, but the loop shifting finger I24 feeds this short portion rearwardly, preventing the improper displacement of the short portion, before it is cut oil. The finger I24 will also act upon all loops as they are held by the looper element, but this serves no useful purpose.

The resilient gripper 94 is tensioned to automatically move laterally from the looper element I02, to provide a suitable space for the descendin needle, and means are provided to shift the resilient gripper element toward the looper element, to clamp the loops thereon, during the swinging movement of the looper element. This means comprises a presser head I21, arranged to engage that side of the resilient gripper element 94 remote from the needle. This head is rigidly secured to a reciprocatory rod I20, slidably mounted in an opening I29, formed in the lug II, and the rod I28 is pivotallyconnected at I30 with one arm I3I of a horizontally swinging bell crank lever, pivoted upon a vertical pin I32. The

other arm I33 of this bell crank lever is pivotally' connected with a link I34, in turn pivotally connected with a crank I25, mounted upon the rock shaft 44.

The coaction of the looper, gripper, cutter and loop shifting arm or element is as follows:

As the needle I6 descends, the looper member swings toward the needle, and when the needle reaches or approaches its lowermost position, the looper element I92 has entered the loop. As the needle starts to rise and about the time that it has passed slightly above the looper element, the

presser head I2'I has moved toward the resilient gripper 94 sufllciently to cause this resilient gripper to grip the loop against the side of the looper element I42, as the looper element is traveling towards its rear position from the needle. The gripper element therefore grips the loop to the looper element as the needle rises and this prevents the yarn from being pulled out of the fabric. When the looper element reaches its rearmost position from the needle the resilient gripper 94 begins to open, as the presser head I21 is now traveling from the looper element and by the time the looper element has again moved forwardly to extend across the path of travel ofthe needle, the gripper element 94 will be completely opened, so that it will not contact with the needle when it descends. .When the looper element I02 is moving rearwardly from the needle, as explained, the movement of the pivot H2 and link III causesthe blade or cutter I03 to turn upon its pivot I05 and the loop upon the looper is severed when the looper element reaches or approaches its rearmost position. The loop shifting finger or element I24 swings simultaneously. counter-clock-wise with the looper mem-' her and simultaneously clock-wise with the looper member but the arm I travels for about twice the distance of the looper member. This positions the free end of the arm I24 well in advance 'ofthelooperelementlilwhentheneedlehas deacended.' It is thus seen that when the looper element has entered the loop produced by the needle in the lowermost position, the free end ofthearm lllis'wellinadvanceofthelooper element and loop. The looper element has thus already entered into the loopand received the loop before the arm I has started its rearward movement from the needle. Further, the looper elementhssmovedrearwardlyasubstantial dis tancebefore the arm I has moved rearwardly sufilciently to eng e the loop thereon and shift the same rearwardly. It is' thus apparent that thearm illdoesnotservetopasstheloopupon the free end of the looper. as the loop is already thereon, but simply to work the loop further back upon the looper'element.

Means are provided to cause the needle to idle at intervals for producing spaced tufts or'spaced during four cycles of operation,

groups of tufts. This means comprises areciprocatory bolt I, sliding in, an opening ill, formed in the head ll. At its forward end this bolt is provided with an upturned head III, to.

engage beneath the arm 80,, when the bolt I" -is'prolected forwardly into the path of travel of this am. This bolt is longitudinally adjustably connected with a coupling I, the upper end of which is rigidly connected with a rod I. 'lhe rod I is pivotally connected with a pin or pivot element Ill, eccentrically carried by a rotary element or wheel I42. This rotary element is rigidly mounted upon a'shaft I, journaled in bearings formed in a housing I. The shaft I carries a worm wheel I, rigidly secured thereto and this worm wheel engages a worm wheel I, rigidly secured to the drive shaft 20. The worm wheel I makes seven rotations to one rotation of the worm wheel I. It is thus seen that the movement.of the pin ill eccentric with the rotating wheel I42 will effect a longitudinal movement of the bar or rod ill, which will in turn move the bolt I into and out of the path.

oftheboltwithrespecttotheannllmaybe regulated by longitudinallyadjusting the bolt with respect in the coupling in.

A yarn. pulling device is provided, to pull the yarn carried by the needle from the fabric, when the needle is i ling, comprising a. lever I41, pivotally mounted between its ends upon a fixed bar or rod m. rigid y attached to the head It. The lever I" is pivotally connected at its upper end with a link I which is adjustably clamped to the coupling I, the link. being resilient to compensate for any slight arcllate movement of the upper end of the lever ill. The lever I" is provided near its lower end with a transverse opening III to receive the end of an arm Ill, clamped therein by aset screw ill. The arm Ill carries the eye It.

The operation of the machine is as follows:

In; the present embodiment of our invention, and for the purpose of illustration only. the drive shaft II has a gear ratio with the rotatable element or wheel Mr so that the element I42 makes one complete revolution when the drive shaft makes seven complete revolutions. The needle makes three cycles of operation during the sewing period and is. held elevated or idle ,the work being grips the opposite side of the loop fed one step during each cycle of operation, when the needle is elevated.

The cycles of operation orthe needle during the sewing period isillustrated in Figures 8, 8a. 9, 9a, 10, and 10. Figures 8 and 80 show the first cycle of operation. The needle moves downwardly on the first stroke. Figure ,8, and forms the loop upon the lower side of the. fabric, and about the'time that the needle starts upon its up stroke the looper-enters the loop but the gripper does not as yet grip the loop. Upon the beginning of the upstroke of the needle the loop slides about the looper and that side of the loop next to the cutter is pulleddown ut of the fabric, and by thotime the needle moves upwardly above the l oper and grime h pper to thejooper, Figure 8d. The looper is now moving from the needle and the cutter severs the yarn 'at 2| cutting oil a short tail Ila. The needle now reaches the uppermost position, Figure 8a. and the first cycle is completed, and the work is fed one step. On the second cycle, the needle descends. Figure 9, to form the loop. and the loop is gripped and severed, in the same manner and when the needle reaches the uppermost position the second cycle is completed and the work fed another step. During the third cycle, the needle descends, Figure 10, forming and severing another loop and again rises to the uppermost position to complete the third cycle, and the work is fed another step, F'igure 10a. The idling'period starts after the completion of the third cycle and continues throughout the 4th, 5th, 6th, and 7th cycles. Figure 11 shows the needle held in the elevated position against the down stroke while the eye II is starting to move downwardly and from the eye 28 which is now held at substantially the same elevation with the eye 23. This movement of the yarn pulling eye has caused the trailing side of the trailing loop to be partly pulled from the fabric, and when the work is fed in the next step, Figure lla, the feeding movement of the fabric and the continued pulling. actionv of the eye 23 further pulls the yarn extending from the needle from the fabric. During the fifth cycle of operation the continued pulling movement of the eye 23 further pulls the yarn extending from the needle from the fabric and Figure 12a shows the completion of the fifth cycle and the feeding of the work for another step, and this feeding of the work combined with the continued pulling action of the eye completely removes the yarn from the fabric. This leaves a portion of the yarn carried by the needle and extending beyond the same of sufllcient length to prevent the yarn from pulling out of the needle and to properly form the first loop, when the first cycle of operation is reached.- During the sixth cycle the work is fed another step, but the eye 23 is now traveling in a reverse direction, Figures 13 and 13a, and the same operation occurs during the seventh cycle, with the result that a slack is accumulated in the yarn between the eyes 23 and 20. After the completion of the seventh cycle, the needle is in the uppermost position and is then released to descend upon the down stroke, Figure 8, to repeat the first cycle.

As clearly shown in Figure 8, both sides of the loop are in the fabric. As the needle ascends, Figure 8a, the side of the loop next to the cutter is pulled out of the fabric and-slips around the lower edge of the looper, this slipping action stopping when the needle rises sufhciently so that the gripper grips the side of the, loop next to the gripper against the looper. The short side of the loop next to the cutter or blade should be cut by the cutter, as the looper approaches its rearmost position, but it sometimes happens that this short side will work or bend toward the free end of the looper to such an extent that the cutter may not engage the same and fail to sever the short side at the point 25'. To prevent this from occurring, the arm I24 moves from the needle and simultaneously counter-clock-wise with the looper but faster than the looper and engages this short side of the loop next to the cutter,

shifting it rearwardly and upwardly so that itwill be positioned to be cut by the cutter. The arm I24 will thus push the short side of the loop well up into the space between the then opened cutter or blade and the looper, whereby this short side is cut by the blade.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of our invention or the scope of the subjoined claims.
