I

ln'the present invention as illustrated in the accompanying drawings the principal operations are p'eriorn'ied by a mechanism,

carried hymns of a bench press of well known construction which there is a sta-j tiona'ry bed 1 and a reeiprocat ng head'EZ' movable toward andfrom the 'bed5 theqliead being actuated by a connecting rod 3 eirteiiding from a crank shaft dwhic h is continuouslydriven in any manner and serves to reciprocate the head at the desired rate, parts ofthe rod '3 and crank shaft ebjeing shown in Fig. 1 of the drawing. A rotary carrier 5 is mounted up'on'a fixed vertical 'stu'b shaft I 6 securedto the bed centrally thereof andthe carrier or table 5 is provided adjacent the periphery with regularly spaced pockets 7 each of which is adapted to receive one of the valve members and which servesto support a valve -'1ne1nberwhile the various operations are being performed thereon. The valve from a supply hopper-'8 thrOu'gli-Ptfeed chute 9 in such manner as to supply one valve menberto each pocket of 'thecarrieras the same is rotated." the valve members being dis- 'members are delivered to the rotary carrier charged alter the various operations are coin-f pleted' through a dischar e chute 10 se ured to th e base 'atithe side of the carrier opposite I that at which thefeed chute is located. Fig. 15' of the drawings shows a metallic shell or blank ll'in'to which the p'ackingis inserted by the n a'cihin'e. This blank an enlarged, end 12 which is pi 'ovidedw' arecess to receive the packing, and knew the recess 1-3 the member 11is provided-with an axial bore 14 to receive the valve pin. As shown in Fig. 1 of the drawing, the supply hopper 8 which is adapted to contain a suitable quantity of the blanks 11 is provided with avertically movable oscillatory feed arm 15 which is mounted to swing upon a horizontal pivot 16 at the forward end of the hopper, and carries a vertically disposed segment" plate 17 correspondingto an axial section through a blank to be fed. 7 The segment plate 17 in the movements of itscarrying arm 15, moves from a posltion 1n which 1ts upper edge lies along the bottom of the hopper 8, to a pos1' tion in which said upper edge aligns with the feed chute 9.- The feed chute 9 is provided with a groove 21, which is of the same shape as the groove 20 in the upper edge of the segment plate 17, so that when the upper edge of the segment plate is aligned with the chute, any blanks which are resting in the groove of the segment plate may slide into the groove '21 of the feed chute. The arm 15 projects inwardly beyond its pivot 16, and to its inner end is attached a Vertical actuating rod 22 which carries a roller 23 which engages the under side of a cam 24 fixed to a cam-shaft 25 mounted ina fixed support above the hopper. The upper endiof the rod 22 is provided with a guide slot 26 through which the cam-shaft 25 extends, the rod 22 being retained on the cam-shaft by a suitable retaining washer 27 on the cam-shaft. The

' cam-shaft 25 has fixed thereto a belt pulley 28', over which runs a belt 29 which extends from a pulley 30 secured upon the crank shaft 4. 7

As the segment'plate 17 is moved from its lowermost position through the loose mass of blanks 11 in the hopper 8, some of these blanks will drop into the groove 2-0 and assume a position therein, in which the upper enlarged portion12 fits in the upper enlarged portion of the groove, and the smaller lower end portion of the blank extends into the narrower lower portion of the groove, such blanks being supported with their large ends uppermost. As the plate 17 approaches its'uppermost position, its upper edge will be inclined at an angle such that any blanks resting ;upon the top of the plate, but not properly positioned in the groove will roll 1 off the plateand drop-back into the hopper. The cam 24 is so shaped that the plate 17 will have a dwell in its uppermost position in alignment with the chute 9 suflicient to permit over and adjacent the top of the rotary carrier or table 5, and directly over the pockets 7 of the carrier the chute is provided with a discharge aperture 32 through which the blanks may pass one at a time into the pockets of the carrier. A feeding device is provided for feeding a blank from the chute into each pocket of the carrier, and the endmost blank in the chute is normally held against falling through the aperture'32 by means of a U-shaped retaining spring 33, the legs of which extend along opposite sides of the aperture andreceive between them the lower small end of the blank. The dis charge end of the chute has alcover-plate 34; provided with an aperture 34; which registers with the discharge aperture 32, and the blanks are dischargedfrom the'chute into the into the pockets 7 by a yielclingly supported punch 35 carried by the movable head 2 of the press. The carrier 5 is indexed during each upward stroke of the head 2 of the press to bring an empty pocket 7 directly beneath the discharge'aperture 32 of the chute, and upon downward movement of the head the punch 35 moves downwardly through the aperture 3 1 into engagement with the endmost blank supported upon the legs of the spring 33, forcing the blank down into the pocket ofthe carrier. Thevpunch 35 is slidably mounted in a casing 36"fixed to the under sideof the head 2, and has at its upper end a head 37 which is engagedby a compression spring 38 interposed between the head 37 and the bottomof the'press head 2. The punch 35 is thus yieldably supported so that the mechanism will not be damaged should a blank become jammed in the discharge end of the chute.

Each of the pocket 7 of the carrier is provided with an insert 39 which. has a central bore 40 to receive the lower ends of the blanks 11, and a counter-bore 41 in which the enlarged packing receiving ends 12 of, the blanks fit, the insert 39 forming a rigid support for the blanks. The carrier or table 5 is provided beneath each of the pockets 7 with anopening 42 through which portions punched out {of the packing may be dis.- charged. 7 v

Means is provided for insuring a. continuous flow of blanks through the feed chute 9, 5 and to this end a vibrator plate 4:3 is secured to one side of the chute by bolts 14:, the plate 13 havinga limited sliding movement on the boltsv permitted by elongated slots 45 in the plate through which the bolts the press.

44w extend. An angle plate46 is secured to end to the plate 43 and at its opposite end to erly positioned in the slot 20 a fixed support, and'acts to move the plate 48 toward the press and to hold the pawl 47 in engagement with the cam '50. Duriiig theupward and downward movements of the head 2 of the press a rapid vibratory motion willbe imparted to the plate 43, andthe plate d6 carried thereby to insure continuous feed of blanks through the chute. The plate lfiezrtends to adjacent the receiving end of the chute?) and prevents entry of any blanks thereto except those which are propof the feed plate. y I V The intermittent indexing movement of the carrier 5 is imparted by an oscillating actuating arm 52 which is pivoted on thevertical shaft 6 of the carrier, the oscillating movement being imparted to the arm 52 from the reciprocating head 2 of the press through a connecting rod 53 which is connected by a vertical pivot 54: to the arm 52, and by a horizontal pivot 55' to a bell-crank 56 carried by a horizontal shaft 57 supported a on the bed 1 and connectedby a link 58 to the head. By the connections'above described, the arm 52 is moved in one direction upon downward movement of the head to the press, and in the opposite dlrection upon Vii.

the periphery ofthe carrier table 5 is provided upward movement of the head.

with pawl-receiving notches 59. whichhave an angular spacing corresponding to the spaclng of the pockets 7 of the carrier, and

Vbetween the pawl-receiving notches 59 are latch-receiving notches 60 which are engaged by suitable locking means on the bed to positively hold the carrier against movement during the intervals between actuations thereof. A pawl 61 is carried by a vertical pivot 62 atthe outer end of the arm 52, the pawl 61 being supported in the plane of the table 5 beyond the periphery thereof, in positionto engage with the notches 59,

and being held normally in engagement with the periphery ofthe'table by a spring 63 connected at one end to the outer end of the pawl, and at its opposite end to the arm 52. The arm 52 has an angular movement greater than that imparted to the table, and

to prevent the pawl 61 from engaging in the intermediate notches 60 at the beginning of its actuating stroke, a blocking plate 64 isv provided, said plate fixedto the bed and positioned to be engaged by the point i of the pawl 61 when the arm 52 is at the end of its'idle stroke. I I

For locking the table 5 against movementwhile disengaged from the actuating 1111152, a latch65 is slidably mounted in a suitable guidehfisecured tothe bed 1', and is pressed toward the carrier by a, compression spring 67. disengaging the latch 65 froin'the notch 60 in whichit is engaged upon the beginning of the active stroke of the actuating arm, the arm 52 and the latch 65 having enacting trip members which serve to release the latch;

The latch 65- has a trip member 68 which lies upon the top thereof, and is connected its rear endto thelatcli 65 by a horizontal pivot-69, and is'normally heldiagainst'upward movement away from the latch 65 by a suitable spring 70. The latch 65' lies in'the Means are providedfor automatically plane of the table 5, and the top surface thereof is in substantially the samepla'ne as the top surface of the table, so that the trip member 68 is supported above the plane of the top of the table. When the'latch 65 is in engaging position, the inner free end of the trip member 68 overliesthe' edge; portion of thertable 5, and is provided atits inner end with an under-cut inclined port-ion Z *on" one side, and a beveled vertical face-72 on the other side. The actuating arm 52 has a trip extension 7 3 which is providedoh one side with a beveled lifting edge 7% which en gages with the inclined under-cut POTtlOH Tl of the trip member 68, and with an ang'ulai'ly disposed vertical face which engages with the beveled face 72 of the-tripmember 68.

Fig. 2 of the drawingshows the actuating arm 52 in the position which-it occupies at the completion of the down stroke of the press head 2. As the vpresshead moves up wardly, the actuating-arm =52will be swung toward the left from the positionshown in Fig. 2, in which movement the pawl 61 will ride off the retaining plate 64 and engage in' the vnotch 59 immediately to the left of said retaining plate. Before the table 5may be actuated by the arm 52, the retaining latch -65 must be disengaged from the table, and

this is accomplished by the trip projection 73 of the arm 52 during the idle movement of the arm 52 before the pawl 61 engages in a notch 59. The interengaging faces 75 of the projection 73and 72 of the trip member 68 being both'inclined with respect to the longit-udinal axis of the latch 65, the engagement of the projection 73with the trip member 68 will force thelatch 65 outwardly againstt'he action of the spring G'T'sufiiciently to" allow the projection 73 to pass the-trip member 68 and to shift the latch 65 clear of the notch (SO-in whic'hit is engaged by thetimethat the pawl (jl has engaged in the notch 59 to shift the carrier. The angular movement of the arm 52 is just sufficient during the upaccidently be discharged onto the table from the feed chute. To insure the proper positioning punch 77, which is formed to fit in the recess 13 of the blank, is secured-to the head 2, and positioned to engage with a blank, in the pocket 7,-which has been delivered thereto from the feed chute 9 after the table has been actuated to shift the pocket containing the blank away from the feed chute.

Along the front of the supporting bed 1. there is secured a supporting block 78, the upper edge of which is substantially at the level of the top of the table 5, and this block forms a support for a reciprocating feed plate? 9 which is adapted to carrya strip of packing material directly over the outer edge portion of the carrier table. The plate 79 is provided with a retaining flange 80 along its inner edge, and 011 the portion thereof overlying the table there is secured a stripper plate8l, which is undercut at 82 to provide a slotfor the passage of a strip 82:3 of suitable packingmatcrial, such as rubber. After each indexing ,movement, the carrier is stopped, with a pocket 7 containing one of the valve blanks, directly beneath anelon'gated slot 84 in the plates 79 and 81. The strip 83 ofpacking material lies between the plates I 79 and 81, and extends across the slot 84. A punch 85 is rigidly secured to the head'2 of the press, and is positioned in axial alignment with a valve blank in the pocket 7 beneath the plate 79. The punch 85'is substantially the same in diameter as the recess 13 of the blank, so that as the unch 85 moves clown- 'wardly through the slot 84 it will press the rubber strip 83 against the upper end of the blank 11, and the upper cup-shaped end of the blank 11 will'act as a die to sever a circular piece of packing which is forced into the recess 13 by the punch To prevent adhesion between the severed 'g'iacking and the lower end of the punch'85, the punch has an axial passageway extending to its lower end, which communicates with a flexible conduit 85 extending from the punch 85 to a suitable source of air under pressure. Air pressure is admitted to the punch at the end of the down stroke of the press head, and enables the punch to be separated from the packing which has been forced into the valve inemberwithout loosening the packing or dis lodging it from the valve memben. The strip 83 of packing 'material is yieldingly held against the retaining flange by a spring actuated pressure finger 86, and may be shifted by the operator, out of alignment with the slot 84, by means of a manually operable trip arm 87 which engages with the strip along the inner edge thereof.

direction while the punch is in engagement with the strip of packing material 88,

the strip of packing being advanced during the movementof the supporting plate 7 9 by means of a bell crank lever 88 which is mounted on a transverse pivot 89 beneath the plate 79 beyond one end of the supporting block 78 and having onearm thereof in engagement with the plate 79. The other arm of the bell crank 88 is connected to a vertical actuating rod 92 which has a lateral extension 93 at its lower end connected to said arm. The rod 92 is actuated in one direction by the reciprocating head 2 of the press as the head approaches its uppermost position and in the opposite direction as the head approaches its lowermost position, the rod 92 being slidably engaged by a bracket 94 secured to the head2. A block 95 is adj'ustabl-y secured to the ver. tical rod 92 by means of a taper pin 96, and is supported by a lever 97 which is mounted on a fixed support and carries a laterally projecting pin 98 against which the lower end of the block 95 rests, the lever 97 being pro vided with a spring 99 which serves to yield-' inglv take the weight of the block 95 and rod 92. The rod 92 is actuated by the bracket 94,

only when the head approaches its uppermost position, and when the head approaches. its lowermost positon, the upper end of the rod 92 being providedat its upper end with a butter spring 100, which is engaged by the bracket 94 in its upward movement, and with a. butler spring 101 resting upon the upper end of the block 95 which is engaged by the bracket 94 in its downward movement. The lever 97 has a serrated upper edge 102 which engages with a triangular pin 103 which projects from the inner side if the block 91 on the feed plate 79. As the press head 2 approaches its upper limit of movement, the bracket 94 engages the buffer spring and lifts the rod 92, swinging the bell-crank 88 about its pivot, and moving the plate 79 to the left shown in Fig. 1. As the plate 79 is moved by the bell-crank 88, the triangular Din 103 slides over the serrated edge 102 of the lever 97, and as the rod 92 is released by the downward n'ioven'ient of the head, 2, the engagement of the triangular pin103 with the serrated. edge 102 of the lever 97 holds the teed plate 79 in he positionto which it has been moved by the bell crank 88. When the "106. which is normally supported below the head 2 approaches its lower limit of move ment, thebracket 94 engages the buflcr spring 101 and pushes the rod 92 downwardly. Since the block% is resting on the pin 98 carried by the lever 97, the downward movement of the rod 92 will cause the lever 97 to swing downwardly about its pivot, releasing the pin 103 from the lever 97. A return spring 104 is connected to the plate 79 and to the bed 1, and acts when the plate 79 is released to shift the plate 79 in a directionopposite that in which it had been previously moved bythe bell-crank 88. During this return movement f the plate 7 9 the punch 85 is in engagement with the packing strip 83 andholds the strip against movement with thefeeder plate. Thus, upon each reciprocation of the head 2, the strip 83 of packing material is moved forwardly a sufiicient distance to bring an unperforated portion thereof to position over beneath the punch 85.

After the packing has been inserted into a valve member and the valve member with the ackin therein has been shifted bthe carrier to another position with respect to the head, the packing within the valve memher is pierced by a punch 105 fixed to the head 2. The punch 105 is so positioned that it is in axial alignment with a valve member in one of the pockets 7, and is of a size to substantially fit into the bore 14 of the valve member, so that when the punch 105 engages punch 105 also serves to discharge the valve members from, the carrier table, the friction a-l engagement between the packing withinthe valve member and the punch 105 being sufficient to cause the valve member to be lifted by the punchout of the pocket 7..

The punch 105 is provided with a follower lower end of the punch, and is provided with an aperture through which the punch. is

forced when the follower 106 engages the top of the rotary table. The follower 106 is suspended from the head2 by means of vertical bolts 107, whichare secured at their lower ends to the follower 106, and are slidably mounted at their upper ends in the head 2. The bolts 107 have heads 108, slidable in counter-bores 109 in the head 2, and the follower 106 is yieldingly held in its lowermost position with respect to thehead 2 by springs 110' surrounding the bolts/107 and interposed between the head 2 and the follower 106. Asthe head 2 moves downwardly,

the follower 106 engages with the rotary ,table 5, directly over the pocket 7 which is positioned beneath it,-and upon continued movement of the :head, the springs 110 are compressed and the punch 105 is forced through the aperture of the follower 106, and through the packing within the recess 13 of ofthehead, the frictional engagement of the packing with the punch :105 causes the valve member to move up with the punch, and also causes the follower 106 to be held above the lower end of the punch until the follower 106 engages with a'stripper arm 111', carried by a post 112 on the bed 1, whereupon the follower is forced downwardly with respect 7 to the punch untilthelmverend .of the punch is within the follower, and the valve'member is thus freed from The actuating arm 52 has a lateral eXten the punch.

sion 113;adjac'ent,the inner end thereof,.1upon which is pivoted a discharge chute 114, which is normally held in a position in which the,

the valve member. .Upon upwardmovement rear end thereof abuts againstthe outer face of the projection 113 by acoil spring 115 connected at one end to the chute and at the other to the arm 52. During the movements of the arm 52, the chute 114 moves beneath the foll,o wer"106, and the movement ofthe chute 1l4'is so timed that it occupies a position beneat-hthe follower at theinstantQ- when the follower engages the stripper arm 11, so thatlthe valvemembers when freed from the punch 105'olrop into the chute 114 and are dischargedfrom the clmtef1-14'into thechute 1.0 mounted on thebed 1.

i When the actuating arm is i'ntheposition shown in ig. 2, the head is in its lowermost position and thechu-te114 is in engagement with the front side wall of the chute 10, in

which position it is entirely in front of the follower 106. As the actuating arm" 52-is swung tothe left, as shown in ,Fig. 2, duringupwardmo-vement ofthe head 2, the chute 114 remains in the position in (which: it is shown in Fig' 2, until the outer end of the projectiont113 has been turned su-fiiciently Z with respect to-the chute to engage the rear.

end wall thereof, whereupon the chute 114' moveswith theactuating arm 52. -By the time the chute 114 begins to move, the fol-* lower 1.06 and the punch with the valve member sticking to the lower ,end thereof have been raised sufficiently top'ermit'the chute to move beneath them. "It sometimes happens that there'is sufiicient adhesionbetween the packing inthe valveimember and the under side of the follower 106 tocause the valve member to hang :upon the underv surface of the follower106 after it has been freed from the punch 105. To insure the proper discharge pf valve= members under all conditions, the chute 1114 lSrPI'OVlClGdZWlth a pivoted wiper arm 116, which is connected,-

to :theforward end ofthe rear side wall oof.

, the chute V by a horizontalpivtztlfl, and has a projecting 1 g 8 ,WhiQh sfibelowithe;pivot 117 and engages with the stripper post 112 during rearward movement of the chute. The pivot 117 is provided with a spring washer 118, which causes a suflicient friction between the wiper arm and the side wall of the chute to normally hold the arm in any position to which it is moved. The engagement of the projection 119 with the post 112 causes the wiper arm 116 tobe swung up wardly so that during the return movement of the arm 52, the wiper arm 116 engages the under face of the follower 106 and will brush a valve member sticking to the follower into the chute. The follower 106 has sufilcient downward movement during the movement of the wiper arm 116 across its under face to move the wiperarm to its lowermost position.

In the operation of the machine the rotary carrier table 5 is positioned, during each downward stroke of the head 2 of the press, with certain of the pockets 7 thereof directly beneath and in axial alignment with the various punches carried by the head. I During the downward stroke the punch 85 forces a valve member from the discharge end of the chute 9'into thepocket directly beneath the aperture'32, the positioning punch 77 engages with a valve member which has been previously fed into a pocket, forces the valve memberinto firm engagement with the insert 39-, the punch 85 at the same time engages the packing strip and co-acts with a valve member which has'been previously fed and positioned in the pocket to sever a circular I piece of packing material and force the same into the recess 13 of the valve member, and the punch 105 at the same time-pierces the packing in'a valve member which has previously been positioned in a pocket and had the packing inserted'therein. Upon the up stroke of the head 2 ofthe press, the rotary table 5 is indexed by the actuating arm 52 which in its movement releases the table from its holding latch and shifts the table through an angul ar dist ancecorresp on din gto the angular-distance between the pockets 7, the valve member engaged by the punch 105 being at thesametime lifted out of its pocket in the rotary carrier table 5 and discharged'into the chute 114:.
