BAND-TYING GAUGE.

Application led December 10, 1921.

To affy lz/tom t may coltre/"n Beit known that l, lvrnenn'r Coon, a citizen ol" the United States, and resident of lilolyolre, in the county et' Hampden and State ot lvl'assachusetts, have invented certain new and uset'ul lmproif'ements in Band- Tying- Gauges, of which the following is a specificatie This invention relates to improvements in gauges tor use in tying drivingv bands, ol band-driven machines, with a regulated tension, the improved device being especially adapted l'o-r use in tying the spindle driving bands ol spinning or twisting frames.

The invention has for its object to provide asimple and durable device of the character set `forth so constructed as to decrease the labor and time required in tying bands.

ln the drawings, Fig. l is a side elevation ol the device attached to a spindle bearing and spindle rail ready for use;

l1 .7 a detail sectional view showing the device for locking` the tension regulating,- member; and

Figs. S, i) and l() diagrammatic` views illustrating` the tying' ot a band.

rlibe device comprises an attachment and misitioning;Y member l. which is slotted at its lower end and provided with lugs 2 atthe opposite vertical sides ol the slot. Between these lugrs the lower end oi" a swinginga tension-regulating nienlber 1% is pivotally held. by suitable pivot pin l. horizontal bracket 5 is carried by the member l near its lower end. said socket being on the opposite side oi" the member l 'from the tension member and adapted to extend under the lspindle rail. The bracket 5 is formed with two lugs (5 which extend through the slet in the memb r l and are secured in positien by the pivot pin 4t. The lugs 6 snugly Serial No. 521,435.

t the slot so that there can be no free upand-down-movement of the bracket 5 independently of the member l. The bracket 5 is provided with an elongated aperture T adapted to receive the lower end of a spindle bearing or bolster 8 which depends from rail f) of the spinning trarne.` The aperture 7 is preferably of the same width transversely as the diameter oit the spindle bearing, but has considerably greater length to facilitate its engagement with the bearing when the device is in position for use.

The tension member 3 is formed with an extension or 'abutment 10` at its lower end which is adapted to engage the upper wall of the slot in the member l between the lugs G and to serve as a stop to limit the outward and downward swinging movement or" the tension member away from thesupport or positioning` member l. The tension member f3 is mounted on the pivot 4 between the lugs 6, as clearly shown in Fig. 5. The tension member 3 is normally swung away trom the support or positioning member l, to the limit of the movement permitted by the lug; 10, by a tension-regulating sprinpr ll. One end of this spring is confined in a socket 1Q formed in the member l. and the other end there-of is coni-ined in a socket 13 formed in an externally threaded pltncr or nut lllscrewed into the outer end of a cylindrical bore or passage l5 extending through extension member 3, said bore or passage being' formed in a cylindrical enlargement 16 ot .said member. The nut 14 is provided with an interior angular, longitudinallyextending projection l? which is adapted to be engaged by a wrench 'for adjusting' the uut to 'vary the tension oli the sprintf ll. Said wrench must be inserted through an aperture in the member l and longitudinallv through the spring and passage 15.

The member t is provided at its upper end with an integral bracket 2e which is designed to project rearwardlyv or inwardly rover the spindle rail when the device is in operatis position. The bracket 26 is cut away at Lts tree end to form a notch or recess 2T adapted to bear against the spindle beati ne' 28 between the rail 9 and the spindie lwliorl 29 and close to the said wliorl. Secured to the upper surface of the bracket 26 is e plate 30. the free vend of said plate being cutout or notched as at 3l to fit i ment a'tter the same is swung` a "close to the sp.

connected to the whorl. -V gers quite closely embrace of the whorl and prevent cut away to orm each side oi' vthe .screws 36 and bearing on "end with an arm 39,'the

member l and engaging' in a slot around and engage the spindle bearing 28, said notch being or' such size as to accurately center the bracket 26- on the spindle bearing directly below the spindle whorl. rEhe plate 30 is secured to the upper surtace of the bracket 26 by 'screws and its ree end is formed with the upwardly and inwardly extending guard lugs 38 which fit over the lower flange ot the whorl at diametrically opposite points. The purpose ci these guard lugs is to prevent the band slipping down under the whorl during the tying' opera-tion and also when the tied bandY is released from theftying device and These guard linthe lower liange the spindle being lifted in its bearing. so that the whorl is held in a substantially fixed vertical Vposition with respect to the tying device.

The upper surface of the bracket 26 is the horizontal shoulders the plate 30. Secured to bracket 26 by mea-ns of the shoulders 35, is a 'spring lside .arm 37. "The tree ends ottheseside arms are bent inwardly toward each other and then back upon them- 85 directly below v.selves to form triangular,gripping jaws 38.

These jaws are adapted to be torced over the spindle bearing and to yieldingly engage it in order to hold the tying;- device in position.

The member 3 is provided at its upper free end of which is beveled outwardly and downwardly to torin a cam surface Lll. This cam surface is Vadapted to engage and ride over the upper end o'ta vertically slidable latc 'i l2 and to denress said latch against the pressure of springs 43 when the .-.iember 3 is swung toward the member l. The arm 39 is provided with a locking shoulder' le which is adapted to snap back o the latch bar 42 to lock the tension member 3 against movepredetermined distance toward the spindle. The latch 42 is conlined in a channel 'formed in the member l.. and the sprinfrsvll are mounted in sockets formed in said member. as shown in Fig. 7. A pin l5 mounted in 4l@ in the latch bar 42 serves to limit the movement ot said bar. The latch har atits upper cud is provided with two outwardly extending;

dinger pieces 47.. one on each `side oi"- the arm 39, and said lingers pieces are adapted to befdepressed by the operator when he ('lesires to releaseithe tension member trom the latch 4t2.

The arm 39 is formed broad and 'flat on its upper surface; and at its free or inner end.y that is'tov say. the end that is brought i lle who-l in the act lot the band,` itis yprovided"with two upthe spindle and through the center 48 on each 49 are separa-ted from each other a considter n.

and are on opposite sides of a vertical plane gassing through the center o1 the tension member. These hooks tace toward the whorl when the device is in. position on the spindle rail and are Vso positioned upon the tension member that when said member is in its latched position said lugs will lie close to the whorl on opposite sides ol a vertical plane drawn throughthe` center ot oit the tension member. These lugs are adapted tofengage the two members of the looped band and to maintain said band in engage ment with the whorl.

The arm is also 'formed with two upwardly extending outwardly or forwardly facing (toward the operator) tension hooks (i9, one ot said hooks being arranged atl eac-h side edge of the broad upper surface oi: the tension member so that said hooks are directly -in line with the guide hooks side of said member. The hooks erable 'distance so that the knotted end ot the looped band may lie between them and between the guide hooks, as shown in Fig'. 9.

In Figs. S, 5) and l() the operation ot the tension and guiding hooks is ifllustraterfl. Spindle driving bands are usually formed oit two strands twisted together. loop 'formed at one end ot the band and at the other end the two strands are separated. (lne ct these sepa-rated ends is passed through the said loop in one direction and the other .is passed through the loop in the opposite direction when it is desired to'tie the band to the spindle. lis shown in Fig. t. the separated strands. after they have beenpassed vthrough the loop in the end ot the band` are passed outwardly inopposite directions under the tension hooks 49. (llinf'ionsly. this holds the partly tied band on the top ot the tension member and maintains the two members ot the band in the udc hooks 48. any form oic tension device may be employed to engage the sepathe spindle rail A9 rand to vcause the spring jaws to engage the spring bearing`3'7.

Therecessf 27 of the bracket 26 and the recess '3l ot the plate 30 receive the spindle liearinowand allof these parts'serve to cen- U member l properly and to holdit lll) :ramasse against the spindle rail. The guard lugs 33 fit over the lower iiange Oi.I the spindle whorl. The tension member is free of the latch l2 and 'the spring 1l. forces it forwardly, that is to say, toward the operator, and downwardly to the limit of its movement. The lug l0 serves as a limit stop. The spindle driving band is then passed around the drive pulley or drum and on opposite sides oi.t the spindle whorl and its ends are brought together in front of the spindle whorl and between the guide hooks 4.8. (clue strand oi' the band is passed through the end loop of the band in one direction and the other strand is passed through said loop in the opposite direction. These separated strands are than passed laterally in opposite directions under the tension hooks 49. The operator then pulls the strands laterally in opposite directions with the strands bearing and riding on the tension hooks. This causes the tension member to swing upwardly toward the spindle rail. It will be understood that as the strain is put on the separated strands they are pulled out or unravelled froml the main body of the band. This shortens the band and puts a strain on the tension hooks which forces the tension member upwardly and toward the spindle rail and the guide hooks guide the band and maintain it on the whorl. The an'lount ot strain required to throw the tension member to its latched position will depend upon the adjustment of the spring l1 and consequently this will regulate the amount ot tension on the tied band. lVhen the band has been contracted suiiiciently to place the desired amount of tension on the tension member, said member will have been swung upwardly to its latched position, as illustrated in 2. 3 and 9. This takes the tension of spring l1 oil" the band and by releasing the tension. on the separated strands the partly knotted portion of the band will move into the whorl. The tying of the band may then be completed by tying together the two separated strands and the completely tied band will be in direct engagement with the whorl, as shown in Fig. l0. rlhe guard lugs prevent the band drawing down under the whorl during the tying operation and also prevent the whorl and. spindle being accidentally liz'ted during the tyingoperation. lVhen the tying operation is completed the latch plate 42 is depressed and the tension member thereby released. The device may then be quickly removed from the spindle. Oi: course. the device may be rei leased ltrom the spindle without releasing the tension member` but it is the usual prac- 'tice to release the tension member before dctaching the device 'from the spindle rail.

The invention is especially adapted for use in connection with spindle whorls of large diameter; and the device is so designed that the iinal tying of the band is done with the band in direct engagement with the whorl.
