- Inventor Lew' B. M/Y/e/ Jay 46T ZT A 'with a spring sueh as the spring' 9. These springs are so designed and attached to their respective jaws tiret when the jaw S, for example, is opened quite Wide the end 'l0 of the spring rests en the flat face of the peripheral zone ll of the plate 7. lmmediatelmv Within the zone il there is provided e lil-shaped groove l2, the outermost side of 'which sloees inwardly :from its rim T his groove ii so constructed. that il the jaw 8 is elosed until the end l@ of the spring 9 passes Within the outer rim 13 er' the groove the tensioni of the spring end the sloping side of the groove will cause the ew 8 to be dravmin toward the rim of the plate 7 and to be held quite lirzril". il'ie force with which the jaw' is 'thus drawn toward the rim. reoulatuig themay be well regulated by b tension of the spring- 9. This tension is sul? lieierit te hold a rod eut from the .plastic rope between the jew 8 and the 'face of the' ola-te and oreveut its ralliesas the late Y i a i s l? is rotated, as will more fully hereinater ap pear. i When the rope of quartz Q, which is shown extending outl the nozzle 2, advances a. distance below the shears C equal te the length of red desired the shears are closed thereby euttirigfoll that portion o the rope below the shears. This operation causes one of the tongs oo the conveyor B to catch and hold the rod thus out and it also causes the table l to be advanced so as to carry the rod from underitheshears substitut shew toog ready :ofreoeivirig the next rod. i

The meehariiism, by means of ,which the operations described are carried out, may be described as follows: 'lt will be observed that the blade 6 er the shears fl has coiled spring le mounted ,on an. ol'l'set element l5, 'which spring, as the blade 6 closes, engages the jaw lf3, as indicate-fl iu Fig. 2, thereby presses the jaw 8 the quart-z rope.

,The result is that the forward end of the spring 9 advariees into the groove l2 and the jaw 8 is drawn .in with sufficient force against 'the quartz Jfor holding the rod after it is eut as'fsirplaiued.

lt will be observed 'that the plate 7 is provided on its upper side'vvith s crown tooth gear, ateoth l? of whirh is adapted to be eugaged by a pin 16 mounted above the plate. This pin i6 is connected through the medium et a Wire X with the handle of the blade 6 of the shears C. llllien the blade G is closed in the cutting operation the piu 16 is raised through the .u'iedium of the Wire X with i can take place nient between,

its-.voors inasmuch as the cutting operation is of short duration and the pin is released as soon as the shears are opened at the end of the tut-l ting operation, therefore the piu 16 .is released in plenty of timeto engage the next advancing tooth 18.

velateli Z, Fig. 2. 'lll'ie clutch shown eemprses a spring plate 22 which presses sgeihst the upper sidevof the hub et the geor loreirig the lower hub against a side of the thrust bearing collar fastened te the shaft either directly or with a loose collar interposed be tween.. The tension of the spring; 22 may be regulated by a suitable means, for erA 'ample by s pair el' interlevelrinn huts sland 25 on the end et the sheftQl. With this arrangement, as soon as the tooth i8 strikes the lower end et the' pin i6 the plate l isbrought te a standstill' although the" geer 20 corr tinues to rotate slippiug, ou the shaft ln this new position obviously the veyor is ready for the heilt rod and as sooo as the quartz rope has descended. o, suoieot distance, determined by the length of the roel desired, the shears C are again opereted "with a repetitio or' the .action and-results, ab ready explained in commotion with the euttirig; of the irserod. ,'lhereore, the folate 'l is again advaneed one step esrryingy'a new tong to a position over the shears. .Thereore, by repeatiiip; the operation es many reds may be eut as will lill, the machine, that is, as will bring into use all' of the tongs er; thefplate. "ilillien the plate is filled the operation may be suspended until the rods are removed. Or if desired, the rods may be removed one at a time as they have advanced such a distance that they have eooled sulheieerly te enable them te be removed. This, of course, can loe-doris Without loterferiug with the continued operation or" the machine. i

lo order to remove one of the rodsall 'that is necessary to be done iste seize the rod that is to be removed and at the same drew-- .ing out the jaw 8. This will, et course, lering the tension spring 9, Fig. 2, ou't of the groove l2, 'which will enable the jawv to remain in the position set. lln its set esition the jaw must, of course, be .suliieiently removed froiri the rim orn the plate 7 te allow the quartz rope to pass in between, as already explained. l have found it advantageous to provide, on the upper siee of the blade 6 along; the

setting edge of the sli ars, an ongle plate 26, l

Figs. l and il, which, is slotted as indicated gli operation.

amante to enable it to move in a direction across the front of the cutting' This plate is provided with a compression spring 27 on. its back side tending always to force the plate forward toward the cuttingn edge of the 'blade 6.' The object of this plate is to avoid the quartz rope 'from being drawn. out of alinement by the blade 6 when the blade is restored to its open position alter a cutting operation. lll/'hen the shears are closed in 'the act of cutting the quartz l presses the plate 26 back against the force of the spring 27 but as soon as the shears begin to open the force of the spring 27 is'sulhcient to force the end of the quartz from engagement with the top side of the blade 6 'thereby leav ing the end free and avoiding any danger of the quartz rope being drawn out of alinernent. On the opposite blade 5 of the shears and opposite the angle plate 26, l provide a shield plate 28 having a backward slope away from the cutting edge ot' the blade. The object of this shield is to prevent thle quartz rope from engaging the upper surn face of the blade 5.

The two blades 6 and 5 of course, by any suitable swivel pin or screw 29. Gn the handle side of the blade 5 a stop elernent 30 with a cushioned head 31 is provided in order to avoid any objectionable )a1-ring etect that might otherwise result upon the performance yof' the cutting ber or any other similar material. i

As shown in Fig. 5 the bearing 23 is suitably secured to a traine consisting of an A shaped structure lV, Fig. il, to which the bearing 28 may be directly attached to the cross niember 32 of the A shaped traine. The structure as a whole is shown secured to uprights 3?, Fig. E2, of any suitable character. 'lhc blade 5 of the shears, as indicated, p'crn'lanently secured to the iorvvard part ot the structure lV.

lilith the nrraixgcnient shown 'and dcsfn-ibed'it will be seen that the seizing device comprising the jaw 8 operated autoniatically by the spring la when the cutter is operated. 4That is, each time that the cutter is opera't'ed "the seizing device 8 which has advancedminto operative relation with the cutter is closed by the operation ot the cutter v without any thought on tl1e.paru ot the opericl.

ator who is operating the cutter. Likewise it will be seen that the conveyor B is started and stopped automatically without any thought on the part ot the operator when the cutter is operated. 'The starting operation is initiated at the tiiuc that a. length of quartz is cut. This initiation takes placp through thermediurn of the Wire X which raises the pin 1G. The automatic stopping `takes place after the cutter is opened inasmuch as in opening the cutter 'the Wire X is released and the pin 16 is allowed to'engage are held together,

The cushion 3l may be of rnb` the next tooth on the crown Wheel such as,

the toot-h 18 for example. As soon as this engagement takes place the conveyor stops with the next seizing device in operative relation to the cutter. Therefore, the operation oif the conveyor both as to Astarting and as to stopping is entirely automatic, both operations being controlled through the inediuin of the cutter.
