Referring to the parts shown, A, Figs. 1 to S, is the frame of the machine, supported upon suitable legs B.

O, D, and E are standards secured to the frame to support the working parts of the device.

F is the driving-shaft of the machine, held by the standards and provided at its overhanging end with a step-pulley G upon which to receive an ordinary driving-belt to actuate the machine.

H is a spindle resting in hearings in the standards 0 D, provided at its right-hand end with a circular wad-plate or perforated disk I, rigid with the spindle.

K is a notched or recessed intermitting wheel rigid with the overhanging end of the spindle H.

L is a crank for turning the wheel If at intervals, held upon a shaft M, resting in bearings in the standards C D.

N is a pinion on the driving-shaft F engaging a gear 0 on the shaft M, by means of which the latter is turned to actuate the wheel K and spindle II.

P is a clutch-section rigid with the pinion Nand with said pinion adapted to turn freely on the shaft F.

R is a sliding clutch-section held to turn with the shaft F and adapted to engage the section P for driving the machine.

S is aleverforcontrolling the sliding clutchsection B for starting or stopping the machine while the shaft F continues to rotate.

T (see also Fig. 20) is a primary cuttershaft, and U (see Figs. 12 and 22 to 24) asecondary cutter-shaft for cutting the center pieces m Figs. 27 and 30, out of the blank disks or wads to form the packing-rings. The former shaft is rapidly rotated by means of apinion V thereon, Figs. 1 and t, engaged by a gear \V, rigid with the driving-shaft F, and the shaft U is similarly rotated by means of a pinion X on said shaft, Figs. 1 and 2, engaged by a gear Y, rigid with the drivingshaft. The pinions V and X are not rigid with the respective shafts T and U, but

splined thereon, so while turning with the shafts the latter may each move endwise through its pinion.

Z, Figs. 1, 2, and 12, is a shaft coaxial with the spindle H, normally rigid in the standard E and connected with said spindle, preferably by means of a conical antifriction-bearing a, as shown in Figs. 4, 10, and 32, which serves to keep the two shafts accurately in line.

A, Figs. 3, 4, and 12, is a carrying-head adapted to slide or have longitudinal motion upon the shaft Z.

B, Figs. 1 to 7, is a camrigid with the shaft M, and O a vertical link adapted to be moved alternately forward and back by means of a roller 1), Fig. 7, held by an extended part 01 of the link in position to traverse the sinuous race in the cam as the latter revolves.

D, Figs. 1, 3, and 7, is a horizontal bar rigid with the link 0 and connected at its opposite endwith a pair of rocker-arms E, Figs. 1, 3, and 4, adapted to turn upon trunnions 0, held by a horizontal floor or plate F, joining the standards D E.

At their upper ends the rocker-arms E engage between lugs d on opposite sides of the carrying-head A, Figs. 1, 3, and 4, by means of which said head is reciprocated by the cam B along the rigid shaft Z, the bar D sliding through a bearing in the standard D. At its upper end the link 0 is connected with the primary cutter-shaft T by means of a pin e, Figs. 7, 33, and 34., projecting from a ring k on the shaft and piercing the linle By this means the cam as it revolves serves also to reciprocate the shaft T endwise in its hearings in the standards C D. The shaft turns freely within the ring, the latter being held to place on the shaft by means of aloose washer o and collar 19 made rigid with the shaft.

From the deseriptionof the device so far given it will be understood that in the reciproeatory motions of the parts the carrying head A on one side of the wad-plate I and the primary cutter-shaft T on the other side of said plate move alternately toward and from the plate and each other as the cam B revolves. The wad-plate is formed with six equal circular perforations O 1 2 3 t 5, Figs. 5 and 10, the axes of which are parallel with the axis of the plate. These perforations are equally spaced in a circle concentric with the plate, and within them the blank wads or disks 9 of packing material are received and the several operations of forming the rings successively performed. The carrying-head A is coaxial with the wad-plate and formed,

with circular longitudinal openings, Figs. 2 and 3, opposite and in line with the respective openings 1 to 5 in the wad-plate for holding tools in position to enter said latter openings as the head is moved forward. The middle standard D, Figs. and 29, is likewise perforated for holding horizontal parts and tools opposite and in line with the openings IIO .eeaeos 1 to 5 in the wad-plate to coactwith the opposing'tools in the'carrying-head, said five openings in the carrying-head, the wad-plate, and the standard D being in line one with another.

G, Figs. 4, 10, 11, and 12, is an inclined feeder for the device, held adjacent to the front face of the wad-plate I, having a race or channel f, down through which the blanks or wads g descend, the wads being supplied to the feeder by hand. The feeder is formed at its lower end with an angular part h to arrest the downward-moving wads and hold the lower one exactly opposite or in front of the opening 1 of the wad-plate. When in this position, the wad is driven laterally into the opening by a plunger vi, FigsJ l, 4, and 11 to 17, held in the carrying-headA", when the latter is moved forward, as already described,the wad when driven home resting against a rigid stop or backing It, held by the standard D,as shown in Fig. 20. The feeder is held to place by a stand w, Figs. 10 and 12, secured to the floor F. of the machine, a clamping-bolt 'u in the stand occupying a vertical slot 00 in the feeder, which permits of vertical adjustments of the latter to accommodate wads of different diameters.

The intermitting wheel Kis formed with six equally-spaced radial openings 1, Fig. 8,

which are successively entered by the pin m,

occupied by the one ahead of it, the plate resting for a time after each advance motion. A wad is driven into each opening in the plate, as above described, as the latter is turned to bring the openings successively into, position, and each wad after being advanced to.

the'position 2, Fig. 10, opposite. the primary revolving cutter n, is acted upon by said cut-' ter moving from the left by the reciprocating link 0, as stated. This cutter forms a cir-' cular kerf or incision 1' Fig. 27, half-way through the wad, the latter being held against displacement. from the pressure of the cutter by. a spring-actuated block or backer 0,.of'

wood, Figs. 1, 12, and 20,'supported by the carrying-head A and advanced against the wad by a forward motion of said head; An-

other shift of the wad-plate brings the open M, will be clearly understood by viewing Figs.

ing holding the incised wad to the position 3, where the wad is acted upon by the secondary cutter 19, Figs. 1, 12, 22m 24, moving from the right, held in the secondary cutter-shaft U, supported by the carrying-head A. The cutter 1), acting on the uncut side of the wad, completes the severing of the center piece m Fig. 27, from the outer part'or ring Z without, however, displacing the parts. The two cutters n and 'r are adjusted to describe cir cles of equal diameters, so as to form a straight and true hole through the wad. The next turn of the plate brings the wad to the position 4., Fig. 10, where the center piece m is driven out of the ring Z by a spring-controlled punch r, Figs.21, 30, and 31, and, when the completed ring reaches the position 5 by another turn of the plate I it is pushed out of the latter by a discharger 5, Figs. 4 and 31, rigid in the carrying-head A, into a spout or conveyer H, Figs. 4, 10, 29, and 31. This conveyer is a hollow inclined body supported from the standard .1) by a bolt or stud 5 Figs. 4, 29, and 31, adjacent to the rear face of the wadplate. The conveyer is formed with an opening t opposite the opening 5 in the wad-plate, through which opening 25 the ring 1 is pushed by the discharger 3 into the conveyer, as shown. I

The several actions performed upon the wad and the parts thereof while in the openings in the wad-plate are simultaneous, the actions all taking place at each'forward motion of the primary cutter-shaft T and the carrying-head A, as above described-that is to say, at each advance motion of these parts a fresh wad is 7 taken into the wad-plate at 1 and a completed ring is pushed outof'the plate at 5. The parts of the machine are so timed that these ad- Vance motions of the shaft T and .the'carrying-head occur during theintervals of rest of the wad-plate and the intermitting wheel K, c

said plate and. wheel in their turn moving while the shaft T and the carrying-head are back'o'ut of the way. This harmony of action among the parts of the machine results from shaft 7, it is formed with a downwardly-projecting part 25, Figs. 1, 3, and 12,.adaptedto traverse in a longitudinal race between guidestrips'u, u' on the flo'or'F. Also in construct- IIO ingthe machine the wad-plate is pierced by openings y, Fig. 5, which pass upon'longitudinal pins 2, Figs. 10 and 32, projecting from the hub a of the intermitting spindle Hfto accurately determine the relative position of .said'plate and hub. By these means the'oper'ating-tools i 0 s, &c., carried by the carry:

ing-head, are caused to always centrally enter the openings in the wad-plate at each forward motion of the head.

The action of the crank L, held bythe shaft 8 and 9. As the crank turns th pin m will strike into an openingfl in the wheel K, as appears in Fig. 8, and turning the wheel through a one-sixth'revolution the pin will .pass out of the opening,'as appears by dotted'position v in Fig. 9,'leaving the wheel in position for the pin to enter the next succeeding opening asthe crank comes around. By. this means the wheel and the wad plate I are turned intermittently through exactly one-sixth of a complete revolution at each action of the crank. It is necessary that the plate I be maintained accurately in position during its periods of rest and while the operations above described are being performed upon the wads. To insure this, the intermitting wheel K needs to be held exactly to place by positive action during its periods of rest. This is effected by forming said wheel with peripheral circular indentations or recesses 9 between the openings 1 and providing the crank Lwith a circular projecting disk It to occupy the re cesses g while the wheel is at rest. The radius of the recesses and of the disk 72 are substantially equal, so the latter practically fills each recess as it is presented, as shown in Fig. 9, this occurring whilethe crank-pin m is idling or moving around. from one opening 1 to the next in succession. The wheel K and the plate I are thus prevented from shifting until the former is again engaged by the pin of the crank. The disk ha is cutaway to form a circular notch orindentation t to make way for the adjacent edge of the intermitting wheel while the crank is acting on the wheel, as stated, the radius of the notch 2' being equal to that of the wheel. The relation of this notch 71 with the wheel is shown by the dotted position of the crank in Fig. 8.

The cup a holding the wooden body 0, Figs. 1, 12, and 20, is formed with a lengthened reduced part or red 1), extending back through abearing in the standard E, the rod being, provided with a spiral spring 0 in a hollow barrel (1', held rigidly in the carrying head A by a set-screw e. Thisallows the body 0 to yield if too hardly pressed, and by means of a screw-nut f, threaded on the rod against the barrel (1, the end pressure of the body 0 against the wad may be regulated.

The punch 0, Figs. 21 and 30, for displacing the center pieces of the rings is also preferably provided with an actuating-spring g in a barrel 72 held rigidly in the carryinghead A by a set-screw 11, having an adjusting threaded nut To for setting the punch.

The standard D holds a body Z, of wood, Figs. 1 and 12, opposite the secondary cutterhead 1)", with its free end adjacent tothe rear face of the plate I to hold the wad against the thrust of the secondary cutter p.

The wads, Figs. 10 and 26, are slightly larger in diameter than that of the openings in the plate I and enter the latter snugly, and it sometimes occurs that a wad may enter an opening irregularly or improperly and catch on the side of the opening or otherwise, resulting in bringing an unusual pressure against the primary plunger 1', with a liability to overstrain the parts. These accidents are provided against by the following means: The plunger, as shown in Figs. 13 to 17, is held in a hollow barrel m, resting in the carrying-head A, having at its inner end a block or shoe or, adapted to move longitudinally in the barrel. This shoe and the inner end of the plunger are pierced by an axial threaded rod 0, upon which is placed a spiral spring 17'. The rear end of the rod is held to move freely through a sleeve r, threaded in the rear end of the barrel, serving to confine the spring between its inner end and the shoe n, a turning of the sleeve one way or the other serving to regulate the tension of the spring. Thus should the plunger at any time encounter a misplaced wad, as stated, it will yield backward against the spring, the parts as suming the positions shown by dotted lines in Fig. 16.

8', Figs. 1, 3, 6, '7, 10, 12, and 18, is a horizontal bar resting upon the door F and joined to the lever S, as shown. This bar pierces the standard D and the stand 20 under the feeder G, having an upturned part or hook t at its free end. The carrying-head A is formed with a vertical tubular part u, holding a trip-bolt '0', with its lower end adapted to engage the hook t. The barrel m is formed with a ledge 10', Figs. 12, 16, and 17, and the trip-bolt v is provided with a horizontal bent finger 0c, the free end of which norm ally rests upon the ledge 10, as shown, said finger occupying a vertical slot y in the tubular part it. A spring 2, connected with the finger a2, tends to draw the bolt v downward in position to engage the trip-bar s, as shown by dotted lines in Fig. 12 and in Fig. 17. When the finger .00 rests on the ledge w, the tripbolt is held out of engagement with the bar 3. A longitudinal flat spring 0., Figs. 12, 16, and 17, secured to the barrel 112, has its thickenedfree end in position to engage the end of the finger m and to be engaged by the shoe or when the plunger 2' is pressed backward, as above stated. The surfaces of contact between said shoe and the spring a are inclined, so that when the plunger 71 is pushed back the spring 0. will be pressed outward to the dotted position shown in Fig. 16, serving to disengage the finger x and allow the bolt 2; to engage the trip-bar s, as stated. The pressure against the plunger from the cause stated can occuronly when the carrying-head Ais moved forward, in which case the lower end of the trip-boltis atthe left of the hook I of the bars, so that when said bolt is allowed to drop, as stated, it will catch thehook t, and the succeeding backward motion of the carrying-head will draw the clutch member Rout from engagement with the member P, and so quickly step the machine.

When a wad enters an opening in the plate I improperly, as stated, it needs to be removed. This is effected by means of a discharger U, Figs. 1, 4, and 19, held within the stop 76, provided with a spring 0 to actuate it. The outer end of the discharger is formed with teeth d engaged by a vertical toothed stem 6 held by an enlarged part f of the stop 7c. By turning the stem the end of the discharger will be carried against the misplaced wad, and so force it out of the plate, this being done while the latter is at rest, the machine being stopped, as stated.

The center pieces m are pushed by the punch into a-cavity 10 in the end of a cylindrical body or receiver 2 Figs. 29, 30, and 31, held by thestandard D adjacent to the wad-plate. This cavity opens out at the lower side of the part zithrough which the center pieces drop, as indicated by arrow 00 into some ordinary conveyer or receptacle. (Not shown.)

These packing-rings are required of different external and internal diameters, and to produce the various sizes required a series of wad-plates I are supplied for the machine uniform in make except asl to-the diameters of the openings 0 to 5, which vary according to the diameters of the primary blank wads previously formedby'means not involved in this invention; also, in forming these'plates it'is sometimes found desirable to flute the openings therein, as shown in Figs. 5 and-6, to hold the blank wads from being turned by the action of the revolving cutters n and p.
