Specification of Letters Patent. Patented N 24,, 1914,,

Application filed. May 13, 190?. SerialNo. 373,450. i i i tus the tube is passed through areceiver which approximately fits the exterior wall of the tube, and a feeder which preferably consists ofa cylindrical plunger, is placed w1th1n "the tube approxnnatelyfitting the interior wall thereof, so that the tube occupies the annular space between the exterior.

ofthe plunger and the interior of the recelver. Thewalls of the ICCGIVQI. and feeder adjacent to the tube are provided with air pressure above that of the atmospheric, or

using both these forms of pressure producing devices in conjunction, particularly when it may be found desirable to utilize a pressure greater than that of the atmosphere. The pressure is applied intermittently and alternately to the interiorand exterior surfaces of the tube, and the latter is ad *anced while thus held either by the inner or outer side ofQthe tube, and .while released on the other side. In practice it is believed to be preferable to feed the tube while held by its inner wall, the feed memher or plunger beingmoved longitudinally to the desired extent while holding thetube,

and while the outer surface of thetube is released from the receiver.

In the apparatus, which is shown and descrlbed herein, the tube 1.5 1s within the conduit or receiver 16, and the tube carrier and feeder, which consists of a plungerl'lis within and concentric with the receiver, ap-

proximately fitting the interior wall of the tube.- For convenience in adaptingthe apparatus for the manipulation of tubes of 1 different sizes the receiver 16 is preferably made easily detachable, being, as herein shown, .remmably attached to the spindle H 18, WlllCll is mounted 111 any sultable way,

as in the boxes or bearings 19 mounted in the headQO, which is or may be similar to the head of a lathe and may, for convenience in cooperating with tube cutting or other adjunctive mechanism, be mounted upon abed 21. Any suitable means asa screw or screws 23 maybe employed for removably holding the receiver 16 in position in the spindle. By removingthe screw the spindle.

receiver may be withdrawn and other receivers substituted of sizes and forms suited for the different tubes to be operated upon. In some instances in which this process of feeding and holding the tubes may be employed, it may be undesirable or unnecessary to rotate the tubes, in which case the receiver 16 and the plunger 17 need not be supported for rotative movement. But for many purposes, including the purpose of cutting tubes into gaskets, illustrated herein, it is desirable to rotate the tube. For this reason the spindle 19 is mounted for rotation, as herein shown and is provided with a pulley 2st, or any other convenient means for imparting the rotative movement. In such'cases also it is usually desirable to rotate the plunger 17 coincidently with the receiver. In the embodiment here shown the receiver and the plunger 'are mechanically clutched or coupled together by a coupling 25, which is fitted upon a hub 26 of the plunger and connected therewith by means 'of a spline 27, which serves to rotate the. plunger with the coupling while permitting the longitudinal sliding movement of the plunger within the receiver and coupler. The coupling is preferably provided with an annular shoulder 29, which fits within the rearward end of the spindle 18 and centralizes the coupling and the plunger with that spindle.

Asa means for insuring coincident driving engagement between the receiver and the coupling, one of them, in this instance the coupling, is provided with projections 30, which enter corresponding recesses 31 in the end of the receiver or the end of the The coupling being thus interlocked with the receiver and splined to the plunger, insures their coincident rotation.

For convenience in readily disconnecting the coupling to permit the withdrawal of the plunger from the receiver and the putting in of a new tube, the coupling is secured to the spindle by means of a screwnut .83 which for convenience in handling may be provided with a handwheel rim 3%. This nut is threaded upon the end of the spindle 18 and is provided with an inwardly projecting. flange 35, which is interrupted at two or more portions preferably opposite each other to receive the outwardly projecting wings 36 of the coupling 25, these wings being preferably beveled, as shown by shade lines in Fig. 5, to insure easy engagement with the coengaging portions of the flange 35. By screwing the nut 33 in one direction the coupling is clamped securely against the end of the spindle, while by turning the nut in the opposite direction to the position shown in Fig. 5 the coupling may be retracted, the wings 36 passing out through the coinciding interruptions in the flanges 35. For convenience and certainty a sufiicientdistance to permit the nutto rotate far enough to insure clamping the coupling against the end of the spindle.

The surfaces of the receiver 16 and plunger 17, which are in contact with the outer and inner walls, respectively, of the tube,

are adapted to serve as pneumatic grippers or holders cooperatingto hold and advance the tube at the desired times and to the desired extent. The plunger, which in thisinstance is shown to be the feeding or advancing member, is provided with grooves 44. which are herein shown to extend circumferentially around the plunger and serve as passages for the air in forcing or inducing pneumatic pressure. These passages are connected in any convenient way through the rearward end of the plunger, either with exhausting apparatus or air compressing apparatus, which may be like that conventionally shown in Fig. 11. In the present instance, the plunger is mounted for rotation upon a non-rotating spindle d5, which is provided with an air passage &6 extending longitudinally within the spindle to the reardward end thereof. At its front end the air passage d6 communicates outwardly by means of the air holes i7 and circumferential grooves l8 with the continuing passages 41-9 leading to the circumferential grooves 4A on the outer surface of the )llll'lger, thus affording continuous air communication between the latter grooves and the air duct or conduit 16, whether the plunger is rotating or stationary. These grooves are herein'shown to be only two in number and situated only at the front end of the plunger, since it is desirable in this particular case to grip the tubes at that end, so that the tubes may be fed forward nearly their entire length before their rearward ends reach and uncover these grooves. Ubviously however, the grooves may be extended farther over or completely over the surface of the plunger. The receiver 16 is also shown to be provided with circumferential air grooves 51, which for the reason just given are also preferably limited to the front end of the receiver. These grooves communicate with the longitudinal groove or rooves 52 which may extend to the rearward end of the receiver, or may, as herein shown, communicate with an annular recess 53 in the interior of the spindle, or the exterior of the receiver. At its rearward end the recess communicates with the air duct 54, which extends to the end of the spindle and communicates with a duct 55 of the coupling 25, air-tight connection being insured if necessary by means of a rubber washer or gasket 56. At its inner end theduct55 extends into communication with the duct 57, which extending through the cross duct 59 and longitudinal duct 60, to the end of the spindle; and thence to the exhaust or pressure producing means.

The spindle 4:5 is supported at its rearward end by a spindle head 62; and the ducts 16 and 60 which communicate independently of each other with the air grooves 1 1 and 51 of the plunger and receiver, respectively, are extended through the spindle support 62; and their connection with the air exhausting or compressing apparatus, as the case may be, 1s controlled by means of a valve 65, the construction and operation of which will be hereinafter more particularly described.

The description thus far given relates to a single receiver 16 and a single plunger 17, and this receiver may be efficiently served by such a single plunger, which after feeding one tube as far as it will go can be With-- drawn from the receiver and a succeeding tube be inserted. But to expeditethe operation of the device by lessening the time during which its feeding operations are interrupted, I preferably provide a plurality of these plungers, so that while one plunger is performing its feeding operations another plunger may have a new tube mount- 1 ed upon it in readiness for the next feeding operation. Any desired number of these plungers may be employed. I have, however, shownherein but two plungers, extend ing in opposite directions from the support 62, which thus becomes a sort of monitor or turret head, which is, mounted for rotation upon a stud 66, which is clamped or otherwise secured in the sliding head 67 mounted on the feed bar 68. The spindles 15 are secured to their supporting monitor 62 in any convenient way. The plungers 17 are mounted on these spindles, being held against endwise movement by suitable coli lars or shoulders 70 and 71. WVashers 72.

a direction parallel with the longitudinal center line of the receiver. As herein shown the monitor head is supported upon a feed bar 68, which is mounted for sliding move ment in any COHV6Il16I1tfWty,.iLS upon the 65 front side of thehead 20 (Figs. 1 and 2).

For convenience in allowing the head 68 to be drawn backwardly so as to retract the forward plunger 17 from the receiver with out also drawing the feed bar backwardly,

the head isfittcd for sliding movement upon thefeed bar, so that itmay be drawn back to its dot-and-dash line position shownin Fig. 1. When in its forward or feeding position shown in; full lines in that figure, the head abuts against a stop and is locked in that position by any suitable means, shown to consist of a mutilated cylindrical bolt 76, which when turned to the position shown in Figs. 1 and 12 looks thehcad 67 in feeding position; but when turned about 180 degrees from the position shown in Figs. 1 and 12 brings the recessed portion 77 of the bolt into the pathway of the feed bar68, thus unlockingthe head and permitting it tobe slid back and forth, this movement being generally and preferably effecterl by hand.

As a convenient means for automatically reciprocating the feed bar 68 to impart the longitudinal feeding movements to the plunger 15, the machine is herein shown to be provided with a cam 80, which is mounted upon a cam shaft 81 mounted for rotation in suitable bearings 82, herein shown to be appurtenant to the bed 21 of the machine.

This cam shaft may be driven from some other portion of the machine, or it maybe of the feed bar 68 so as to correspondingly vary the extent of feed of the tube, the (111V: ing connection between the lever 87 and the feed bar 68 is in the form of a slotted cross head. The upper portion of the lever 86 is provided with a slot 88 (see Figs. 1 and 8) in which a connecting pin 89 is mounted for longitudinal movement, being secured at any desired portion lengthwise of the slot bymeans of a nut 90' and washer 91.

To facilitate the accurate setting of the connccting pin to the several positions required for predetermined amounts of feed, the surface of the lever 87 is provided with suitably graduated marks 92 which maybe read in conjunction with a zero mark upon the washer 91, the edge of whichmay be beveled so as to be read more easily. The rearward cylindrical end of. the connecting pin 89 fits in a sliding block 941 which is fitted in sliding ways in the crosshead 95 appurtenant to the feed bar 68 (Fig. 8).

In most cases it will be found desirable to have the plunger 17 come to a uniform position at the forward end of its stroke,

whatever may be the variations in the length of the stroke, confining those variations to the rearward end of the stroke. In the present instance this is accomplished by making the slot 88 of the feed bar 86 coincident in position with the slide-way for the block 91 in the cross head 95, when these parts are in their forward position shown in Fig. 1, in which coinciding position it will be found most convenient to make the adjustments of the connecting pin 89.

The flow of air to and from the receiver 16 and plunger 17 through the ducts and 16, respectively, which determine the application of the pneumatic pressure, is controlled by means of the valve 65, which is preferably of a cylindrical form and is mounted for sliding movement in the stud 66, as shown by a comparison of the position of the va ve in Figs. 3 and d. In the arrangement shown in Figs. 3 and 4 it is assumed that the pressures are produced either by exhaustion alone, or compression alone,not by a combination of both.

The end of the valve is connected with any suitable exhaust or pressure producing apparatus like that shown in Fig. 11, by means of a tube 98 which ,is either jointed or flexible to permit of the longitudinal and transverse movements of the valve. The duct 99 extends from the tube 98 through the outwardly opening passage or passages 100 to the distributing passage 101, which In order to operate the valve 65 while permitting it to be moved back and forth with the longitudinal movements of the plunger 17, the front end of the valve is connected with a valve lever mounted on the rock shaft 106 which is journaled for rocking movement with its axis in a parallel relation to the feed bar 68 and the receiver 16.

The shaft is rocked by means of an arm 10? pivotally connected to the connecting rod 108, the opposite end of which is pivotally connected to a cam arm 109 which is mounted upon a pivot stud 110 and is provided with a pin or roll 111 engaging in a cam operative engagement with the valve 65 during the longitudinal movements of the plunger 17 and its monitor head 62 that valve lever is mounted between suitable end bean.

roclr shaft 106, while remaining in driving engagement withthat shaft" by means of a key or spline sliding in a suitable splineway 116 of the shaft.

in order to illustrate one of the usefulapplications of this invention, the machine is herein shown to be provided with a cutting apparatus for cutting rings from the end of the tube as the latter is intermittently projected beyond the end of the receiver 16 and feeder 17 Various instrumentalities may be thus employedfor cutting off these rings. 1 have, however, herein shown in a general way an apparatus which has been devised for this purpose and which is shown, described and claimed in co-pending applications of the present applicant and another. That portion of said apparatus which is shown herein consists of a rotating disk cu ter 118 which is mounted upon a suitable spindle 119 rotating in suitable bearings 120 and provided with a pulley 121 driven by a belt 122 from overhead shafting or in any other convenient way. The bearings are supported by suitable slides and swivels which enable the cutter to be swung to any desired angle relative to the tube, and to be reciprocated so as to carry the edge of the cutter through the wall of the tube in a line 123 coinciding with the desired angle of the cut. The mechanism by which the desired sliding movement is effected is contained in the cutter-head designated in a general way by 12 1 and is driven by a suitable shaft by means of the bevel gear 125, which in turn is driven by the bevel gear splined upon the cam shaft 81, but journaled in the depending bracket 127. Being thus driven by the shaft 81 the cutter head and its mechanism may be operated in proper synchronism with the cams 80 and 113, which control the actuations of the feedin mechanism and its pres sure valve. It is not considered necessary to give a detailed description or drawing of this cutting mechanism, since its details form no part of the presentinvention, and other forms of apparatus might be substituted for cutting off the rings, or fol-performing any other desired operationupon the tubes in conjunction with the feeding mechanism, which is the subject matter of the present application.

The operation of this apparatus is as follows :The plunger 17 being withdrawn from the receiver, the tube is placed in position upon the plunger and the latter is carried forward by pushing the sliding head 6? forward against the stop 7 5 of the feeding bar and locating it in that position by means of the bolt 7 6. The coupling 25 is then adjusted to its seat against the end of the receiver 16 and its spindle 18; and is fastened to that position by means ofthe clamp nut 33. The forward feeding movement then begins. Assuming that the tube 98 is connected with exhausting apparatus, the valve 65 when in the position shownin Fig. 3 clirects the exhaust to take effect through the duct and the grooves or recesses 51 of the receiver, while permitting atmospheric pressure to enter throughthe relief passage 102 and duct 416, thus holding thetube outwardly against the inner wall of the receiver 16 and releasing the plunger17. The latter is then drawn backwardly to the required extent by i the operation of the rotating cam 80. lVhen the plunger reaches its rearward resting position the valve (35 is moved to the position shown in Fig. 4, thus connecting its distributing passage 101 with the duct 46 and grooves 4st ofthe plunger and at the same time admitting atmospheric pressure through the ducts 103 and 60 to the grooves 51 of the receiver, thus pressing the tube inwardly against the plunger and releasing it from the receiver. The width of the distributing passage 101 of the valve relative to the ducts 4:6 and ($0 is suchthat when the valve is moved from one position to the other, the exhaust takes full effect upon one of those ducts before being shut off from the other duct; or at least before atmospheric pressure isadmitted to the other duct, so as to retain the tube at all times under control of the pressure, gaining a hold on one side or portion before releasing the other side or portion. With the tube thus held against the plunger 17 the latter is moved forwardly by its cam, thus projecting the leading end of the tube beyond the front end of the feeder and receiver, where the parts remain while the gasket ring is being severed, or otherwise operatedon, as shown in Fig. 3. Then the valve moved again to the position shown in Fig. 3,.pressingthe tube away from the plunger and against the receiver to permit the plungerto be again retracted with out also retracting or otherwise moving the tube. Thus the forward feeding movements are continued intermittently and alternately,

and also in alternation with the operations of the cutter for cutting off the end of the tube. \Vhen finally the rearward end of the tube passes to or beyond the grooves 51 and elel, and the feeding stops, the screw nut 33 is turned to the position shown in Fig. 5, and the coupling25 is withdrawn as shown in Fig. 6. Then the sliding head (57 is unlocked from the feed bar 68 by turning the bolt 7 6,

andis drawn baclnvardly to withdraw the plunger 17 from the receiver. In thecase of a machine having but a singleiplunger 17 a new tube is then placed in position, the parts are again pushed forward and coupled to the receiver, and the. feeding movement is again resumed. In the case of a machine having a plurality of plungers 17 upon a swinging turret or monitor head 62, the spindle which is out of feeding operationis supplied with a new tube While the other plunger is feeding. its tube forward, the monitor head being turned upon its sup porting stud 66 when the sliding head 67 is retracted so as to bring the plunger carrying the new tube into alinement with the receiver. a

In the case of a machine ope 'ated by compressed air the operation is quite similar; thc principal difference being in the position. of the valve (35, which is the reverse of that required for operating by exhaust and atmospheric pressure. In other words, when employing compressed air the valve 65, when in the position shown inFig. 3, admits the pressure through the receiver to the outer side of the tube, holding the latter against the plunger 17 and continues thus to hold it during theforward feeding movement of the plunger, after which the valve is shifted to the position shown in Fig.4 which admits pressure through the ducts 46 and 4 1 to the inner side of the tube, holding it outwardly. against the receiver and thusreleasing the plunger which is then drawn back. In this case the relief ducts 102 and 103 operate to release the pressure from each of the ducts 4:6 and 60 when the otherof those ducts receives the pressure.

During the time that the projecting tube is being operated upon by the cutter or other means, it may beheld either to the plunger 17 or to the receiver 16 as may be found most convenient or desirable, according to the character of the operation and the direction. in which. it is applied. In the present instance, in which the cutter penetrates the, tube from its outer side and hence tends to press the tube inwardly, it is considered preferable to hold the tube inwardly against haust and pressure blowers being well understood. As this modification is shown, the valve is provided with flexible or jointed tubes 131 and 132, one leading to pressure and the other to exhaust apparatus. For definiteness in description itis herein assuined that the tube 131 connects with an ex-r 1 haust apparatus, while the tube 132 connects with air compressing apparatus. The duct 133 leads from the tube 131 to the distributing passage 13%, these being similar in arrangement to the corresponding ducts and passages of the valve 65 shown in the previous figures. The front or compression end of the valve 130 is provided with a duct 136, which leads from the tube 132 to two distributing passages 137 and 138. The relation of these distributing passages to each other and to the ducts 4-6 and of the plunger-s and receivers, during the movements of the valve, is shown by comparison of Figs. 9 and 10. In Fig. 9 the duct 60 leading to the receiver is in communication with the exhaust, while the duct 46 leading to the plunger is in communication with the high pressure or compressing apparatus, thus serving to hold the tube outwardly against the receiver, with a pressure which is determined by the pressure delivered by the air compressing device, and may be Varied to suit different conditions. Upon moving the valve to the position shown in Fig. 10, the holding conditions are reversed, the duct 46 leading to the plunger being then connected with the exhaust, while the duct 60 leading to the receiver is connected with the pressure, thus pressing the tube against the plunger, at which time the plunger is given its forward feeding movement to advance the tube.

hen using the simple exhaust plan the pressure is obviously limited to that of the atmosphere, whereas bv using forced pressure it may be increased to any extent likely to be found necessary. Although for many purposes the arrangement shown in Figs. 3 and 4, employing what may be termed a single or simple pressure, will be found sufficient for holding and feeding tubes with certainty and uniformity: for

some other purposes it may be found desirable to employ the double acting method shown in Figs. 9 and 10. To effect the change from one to the other it is only necessary to remove the valve from the apparatus and replace it with the valve 130, the length of stroke and time of operation as herein arranged being the same. The cams 80 and 118 are suited for operating the double-acting modifications shown in Figs. 9 and 10, as well as the single acting form shown in Figs. 3 and 4.

.The valve shown in Figs. 9 and 10 is adapted like that shown in Figs. 8 and 4 v to gain a hold on one side of the tube before releasing its hold on the other side of the tube. This is due to the spacing and lapping of the valve passages relative to the ducts 46 and 60.

The monitor or turret 62 may have any desired number of arms. It may be mounted upon a vertical axis so as to revolve the arms in a horizontal plane. But for the purposes now under contemplation it is considered suflicient to have two plungers mounted diametrically opposite to each other upon the monitor head 62, and is considered preferable to swing the plungers in a vertical plane.

Under some conditions, or for some purposes, it may be found preferable to impart the advancing movement of the tube by means of the receiver, using the plunger as the stationary holding member, and sliding the receiver forward and back in its bearings, instead of sliding the plunger as herein shown and described. It may also in some cases be found suflicient to dispense with the air grooves and passages in the receiver or whichever may be the stationary member. In that case the tube may fit the stationary member somewhat closely, so as to hold thereto by friction, while the feed member is being retracted to get a new hold. But for most purposes I prefer to employ air pressure alternately on opposite sides of the tube.

The term super atmospheric is for convenience and brevity herein employed to designate pressures above that commonly designated as atmospheric pressure, the latter of which at no time reaches fifteen pounds per square inch, and varies below that according to the degree of exhaustion or vacuum by which it is induced, whereas super atmospheric pressure, obtained by compressing the air in any of several wellknown ways,may be carried to any degree likely to be desired.

The process which is carried out by the apparatus shown herein forms the subject matter of a divisional application, Serial No. 573,858, filed July 26, 1910.
