WHITE, F BONHAIi/I, TEXAS, ASSIGNOR 0F ONE-HALF TO JAMES H. PHILLIPS, OF BONHAM, TEXAS AUTOMATIC STOP FOB CARD MACHINES Application filed August 21, 1931. Serial No. 558,602.
This invention has reference to a revolving ii at card machine, and has for its object to provide the same with stop motion mechanism, whereby the doll'er and feed will be automatically stopped whenever there is a cessation in the transmission of power to the comb of the machine, and the present application is a continuation in part of my copending application Serial No. 387,936 filed in August 23, 1929.
As is well known, the stopping of the comb permits a choke down if the dofler is not also stopped, which results in injury to the doifer and the clothing thereon as well as injury to the flats and the expense of repairing such in jury is considerable. I have found that such injury can be eliminated if the doffer and feed are stopped immediately upon a stopping of the comb and to this end I have devised a stop mechanism forming part of the means for transmitting powe from the doffcr to the licker-in, and so arranged, to be controlled by the power belt connecting the idler pulley of the card machine with the comb pulley so that in the event the referred eh able period of time subsequent to the stopping of the comb thus preventing further feeding of the material through the card machine.
A still further object of the invention is to provide in a stop device as and for the purpose specified, improved means for transmitting power from the doli'er gear to a pulley having a belt drive connection with a pulley of the licker-in together with governor 40 means operable to immediately interrupt such drive connection when the comb is, for any reason, stopped.
Other objects and advantages of the invention will be best understood from a study of 45 the following description, taken in connection with the accompanying drawings wherein:
Figure 1 is an elevational view of a conventional type of card machine, viewing the same from one side thereof.
Figure 2 is a view similar to Figure 1 viewing the card thereof.
Figure 3 is a sectional elevational view showing the notched end of a shiftable bar engaging a tooth on the hub of a cam lever.
Figure 4 is atop plan view illustrating diagrammatically certainfeatures of the invention.
Figure 5 is a side elevational view of the structure shown in Figure 4.
Figure. 6 is a fragmentary sectional elevational view illustrating certain details of construction to be hereinafter more fully referred to. t
Figure 7 is a fragmentary detail sectional elevational view showing the normal position of a pivoted bell crank when retaining the shiftable bar out of engagement with the tooth on the hub of the cam lever.
machine from the opposite side Referring more in detail to the drawings,
it will be seen that 10 designates generally a well known type of carding machine, the only part of which this invention is particularly concerned being the comb pulley 11 on one side of the machine having a belt drive connection 12 with an idler pulley 13, which pulley structure 13 has a belt drive connection 14 with the tight and loose pulley structure 15; structure 15 having a belt drive connection 16 with a pulley 17 on a corresponding side of the card machine; in addition to the parts just mentioned there is also to be considered, the licker-in pulley 18 on the op posite side of the machine having the belt drive 19 with a pulley 20, and the dofier cylinder 21 provided with a gear wheel 22.
Another known part of the machine to be considered, is the drop lever 9 having a curved end pivoted to the base of the machine, and a free end operating in a vertical guide 23. Pivotally mounted in the guide 23 is a cam lever 24, having its cam head portion 2 1a keyed to the pivot pin 25. On the pivot pin 25 is a tooth 26 adapted as and for a purpose to be hereinafter made manifest, to be engaged bya notch 27 provided in a shiftable bar 28 for effecting a rotation of the cam lever from the full line position shown in Figure 5 when the comb of the machine is stopped. a
pulley 18 f the licker-in.
According to the present invention, the bar 28 provided for the purpose mentioned, at one end is pivoted as at 29 to an arm 30 fixed as at 31 to the lateral end of an arm 32 equipped with a ring or annular part 33.
The referred to drop lever 9 adjacent one end is provided with a depending extension 22a to which is secured as at 34 a stub shaft 35. r Stub shaft 35 adjacent its pivoted end is provided with a collar 36 about which is disposed the ring 33, which latter is keyed to the collar by a set screw or other. suitable means.
As shown in Figures 1 and 6, there is rotatable on the stub shaft 35, the pulley 20, 'which latter is provided with a hub extension 37 to which is keyed as shown in Figure 6, a gear wheel 38 meshing with the gear wheel of the dofi'er cylinder so that'normally, and when drop lever 9 is in its raised or full line position shown in Figures 1 and 5, power from the doffer cylinder is transmitted to the pulley 20 and from the pulley 20 tothe Referring again to Figure 6, it will be seen that the arm 32 is provided with an elongated slot throughwhich extends a relatively small shaft or pintle 39 secured in adjusted position through the medium of collar 40 and lock nut 41. On one end of the pintle 39 issuitably splined a pinion 42 continually in mesh with gear, 38, and on the other end of the pintle 39 is a disk 43 provided with an eccentric pin 44 operating in a slot 45 provided in the lower end of arm 30.
From what has been stated, it will be apparent that during the transmission of power from the dofi'er drum or cylinder to the licker-in, arm 30 will be caused to oscillate or swing back and forth by reason of the eccentric pin 44 engaging in slot 45 and disk 43 is rotated with shaft 39 driven through the medium of gearing 38 and pinion 42 meshing therewith.
i To retain the bar 28 during its shifting movement under action of the swinging arm 30, in the dotted lineposition shown in Figure 5 and with its notch 27 out of engagement with tooth 26,1 provide as shown to advan tage in Fi ure 7, a bellcrank 46 pivoted on a bracket 47 extending laterally from the frame of the card machine.
The bell crank lever 46 has one end 46a thereof engageable with the bar 48 while the other end of the bell crank lever is pivotally connected as at 48 to one end of a governor controlled rod 49 mounted for sliding movement transversely of the card machine adjacent the d'ofier cylinder 21 thereof.
To retain the bell crank lever 46 in the position shown in Figure 7, and the bar 28 in the dotted line position shown in Figure 5, rodv 49 is normally urged in the direction of the arrow 50 in Figure 4 through the medium of a centrifugal governor on that side of the machine opposite to the drop rod 9 as will be presently made manifest.
The referred to centrifugal governor comprises a tube 51 secured as at 52 to one side of the card machine and provided with one or more slots 53 accommodating the pins projecting therethrough from the inner end of rod 49 and connecting with the rod 49 a collar 54 disposed about the sleeve 51 and slidable relative thereto. Collar 54 is engaged by sliding collar 55 on the sleeve. Collar 55 is connected by spring arms 56 to the hub projection 57 of a pulley 68 rotatable on the sleeve and secured against longitudinal shifting movement through the medium of collar 59 and nut device 60. i
. Referring to Figure 2, it will be seen that the groove of pulley 58 receives a run of belt 12, so thatrduring the transmission of power from idler pulley 13 to comb pulley 11, the centrifugal'governor will be actuated, causing the weighted spring arms 56 thereof to fly outwardly to the dotted line position shown in Figure 4 to exert a pull upon collar 55 causing collar 54 to move toward the pulley 58 thus exerting a pull on rod 49 in the direction of the arrow 50 with the result that as before stated bell crank lever 46 is retained in the position shown in Figure 7, and the comb, doffer and licker-in of. the card machine are free to and do operate in the usual manner.
With the machine thus operating let it now be assumed that for some reason belt 12 breaks. In such an event, the arms 56 of the centrifugal governor would assume the full line position shown in Figure 4, whereupon under the weight of bar 28 arm 46a of the bell. crank lever will swing downwardly in the direction of the bracket 47 and collar 54 being free to slide inwardly or away from'the pulley 58, rod 49 would be shifted in the direction of arrow 50a in Figure 4 with the result that bar 28would assume the full line position in Figure 5 with the notch 27 of the bar engaging tooth 26 as shown in Figure 3.
Thus far, it will be appreciated, that upon breaking of belt 12, the comb will stop. However, the dotfer cylinder will rotate sufficiently long enough to cause, through the Indium of gear 22, gear '38, pinion 42, disk 43 and eccen tric pin 44 a shifting of bar 28 while in its fullline position to the left in Figure 5 to thereby swing cam lever 24 in the direction of the arrow in Figure 5 whereupon drop lever 9 will swing downwardly about its pivot.
Thus it will be apparent, that no power will be transmitted from the licker-in to the dofier cylinder with the result, that, upon stopping of the comb, the doffer is also stopped.
, Asis well known, and shown in Figure 2, power from the -doifer cylinder 21 is transmitted to the feed rollthrough the medium of gearing 8 connecting-the doffer cylinder with a shaft 7 which in turn is provided with a gear not shown in mesh with the feed roll gear 6 so that upon stopping of the dolfer cylinder 21, there is no transmission of power from said cylinder to the feed roll, as is apparent with the result that upon stopping of the comb, and doller cylinder, the feed is also sto oped.
lllpon repair or" the broken belt 12, the cardingmachine may assume the regular operation, by swinging the cam lever 2st in its direction opposite to the direction indicated by the arrow in Figure 5 whereupon gear 38 will be moved into mesh with gear 22. As soon as the machine begins its normal opera tion, the centrifugal governor will be actuated in a manner hereinbefore described for exerting a pull on the rod l9 in the direction of the arrow 50 in Figure l to thereby retain the rod 28 in its raised or normal position.
Even though I have herein shown and de scribed the preferred embodiment of the in vention, it is to be understood that the same is susceptible of further changes, modifications and improvements coming within the scope of the appended claims.
