- zine 1, for a supply of flexible paper or other fibrous material hood caps or paper cups or the like, 12. In the particular example illustrated, the vertical longitudinal axes of the container a, to be hood capped and the magazine 1, or the sta k or caps b, therein, are alined.

A vertical stack or pile of caps b, is shown in the magazine 1, and the caps b, of the stack or pile are arranged in reversed position, i. e. all in the same position upside down or with their skirts extending upwardly, and the caps are all more or less closely nested together. The stack of caps b, is loosely arranged in the magazine feed tubel, to freely drop or feed down therein by gravity or otherwise, and so as to be freely movable vertically therein to and above the means for supporting or upholding the stack against dropping from said tube. The'lower end of the magazine or tube is open for successive removal of the bottom caps of the stack, when such bot-tom cap is distorted and pulled down with suflicient force to separate the cap from those above and pull the cap past the 'cap stack support.-

In the particular example shown, the cap stack is upheld in the magazine tube by, several spaced radial lugs'or fingers 1a, rigid d contalner that is 1n cap receiving pos1t1on, and

with and projecting inwardly from a fixe internal annular ledge or rmg 1?), within the discharge mouth or lower. end of the magazine tube. The arrangement, in this example, is such that the bottom ca of the stack rests on the inner ends of te stack upholding fingers 1a, which engage the cap skirt at spaced pointsin a circle around the same, say about midway the vertical length of said skirt, so that the closed end of the cap depends from and a distance below the lower end of the magazine tube, in. other words, the bottom cap of the stack is accessible below the magazine tube: The lower end of the magazine is preferably formed or provided with an exterlor-normally-fixed or rigid abutment wall or ring 10, surrounding the open or discharge end of the magazine. Any suitable stand or support, such as 0, Fig. 3, is provided for and on which reststhe container a, to be'hood capped, and this stand is preferably formed or arrangedato approximately center the container in hood capping position'under and with respect to the column of caps in the magazine.

Any suitable means (n0t'shown) is provided to uphold and support the'cap maga-,

zine a distance above and overhanging the container that is located in hood capping po sition, and in a normally fixed or stationary position with respect to said container and its stand and also with respect to the ca transfer mechanism hereinafter describe in detail.

The problem is to take the bottom cap from the magazine and then reverse the cap, and deliver the same right side up, or, in the particular relation of the example shown, to then apply the cap to hood capping position on and covering the head of the container located in hood cap receiving position.

The drawings disclose one example of mechanism, from among others, that solves the problem and performs the desired functions, and in this example a vertically movable support, such as a slide or bracket is reciprocated vertically between the lower end of the magazine and the head of the container that is in cap receiving position, and this slide or support carries cap holding and grasping means, whereby the cap separation, reversal and applying is accomplished.

The support, that we happen to show as an example, embodies a horizontally disposed bracket or arm 2, rigid with or carried by vertical slide or sleeve 2a, slidably confined to and reciprocable longitudinally of the fixed or stationary guide rod or post 3, suitabl secured to the machine base or framewor; (not shown; and arranged behind or spaced laterally a istance from the magazine 1,and the container stand or other support.

The bracket arm 2, projects laterally from its carrying slide 2a, to a position interposed between the magazine and the head of the any suitable actuating means 1s provided to reciprocate said arm verticallyback and forth between the lower end of the magazine and said container head.

For instance, the arm can be actuated and its vertical position controlled by a pitman or link 4 operated b any suitable part (not shownl of the mac inc, and at its upper end having compensating and yielding operative connection with the arm 2, through the medium of slide bolt 5, and compression spring 6.

The vertical bolt 5, extends and'has limited relative vertical sliding movement through a vertical bore or hole through the arm and the compensating spring 6, surrounds the bolt 5,

- is arranged to provide a yielding downward pressure on the bottle heads and to compensate for certain differences in bottle lengths.

In the particular example illustrated where the vertically movable. support of the cap transfer embodies an arm, such as2, a revers-' ing cap holder and grasping assembly or head7b.

' of the arm 2, fixedly carries or is formed with a transversely-arranged elongated horizontal hub 2b,.the axis ofthe bore of which is at right angles to the longitudinal axis of the.

arm, and forms an elongatedbearing for and receives a horizontal rock shaft 7, that extends and projects beyond said hub and is arranged transversely of the arm. At one pro ecting end,this rock shaft or spindle carries a pmion 7a, fixed thereto, and at its other end beyond the hub 2?), said shaft carries an enlarged head 7 b, ri id therewith and carrying the cap holder and cooperating parts.

The cap holder embodies a plunger comprising a cap-receiving approximately flat disk, face plate or head 8, and a shank 8a, normally rigid with said face plate and centrally and perpendicularly arranged with respect thereto and depending therefrom when the face plate is arranged above head 75.

The plunger consisting of face plate 8 and shank 8a, is carried by the head 7 b, of rock shaft 7, with the face plate arranged beyond an end of the head, and with the shank 8a, extending and slidable through said head head 7 b, is formed with a bore extending completely therethrough and the shank 8a, is slidably confined in said bore to permit limited reciprocation thereof relative to the head. The reciprocation or relative independent movement of the face plate 8 of the plunger, is radial with respect to the axis 7.

The plunger movement of the face plate 8, toward the adjacent end of the head 7?), is limited by engagement of said plate or parts carried thereby with the head, while outward straight-line movement of the face plate away from the head, is limited by engagement of collar 8?), fixed on the opposite projecting end of the shank 8a, with the adjacent end of Suitable spring means is provided constantly tending to yieldingly hold the plunger with its face plate 8 at the limit of outward movement away from the adjacent end of head 7? and with the collar 8?), engaging the other end of said head (Fig. 5). For instance, an elongated coiled expansion spring 11, can be employed for this purpose, extending across the collar 8?), and at its two ends operatively coupled to suitable means in such manner that the constant tendency of the spring to contract acts on the plunger to force the same outwardly. In the form shown, the flexible distended spring is bent to U-shape with its central portion traversing the outer end of the collar 8?), which is formed with a transverse groove in which the spring is seated. The two legs of the U-spring extend forwardly beyond opposite edges of the head 7 b,

diametrically with respect to the axis 7. The

and at 'their'free ends are coupled to levers- 12, pivoted to the face plate portion of the plunger and hearing or fulcruming against the adjacent endof the head 7?), in such manner that the spring is always distended under tension and acts on the plunger to project the same and its face plate outwardly as hereinbefore described.

The collar 8?), carries a pivoted vertically swingable detent or latch 14 provided with a vertically swingable weighted arm 14a. This latch is designed to assume locking position to hold the plunger at its approximate limit of inward movement or in withdrawn position (see Figs. 12 and 13) against the tension of spring 11, for a certain purpose and under certain conditions, and to automatically swing to and from such locking position under other conditions and positions. The latch 14 is in locked or looking position when swung in between the collar 8?), and the adjacent end of the head 7 b, with the nose of the latch abutting the adjacent end face of the head 7?).

The face plate 8, of the plunger is provided with a 'pair of radially-projecting diametrically opposite rigid arms, at their free ends these arms are arranged and designed to abut the normally fixed end surface 10, of the cap magazine and limit the forward movement of the face plate toward the lower end of the magazine, for a definite purpose. The radial arms of the face plate 8 are longitudinally slotted and each formed with a pair of inwardly or rearwardly projecting ears But, between which the levers 12, are arranged and swingable on transverse pivots 12a, carried by said ears 8d. The two levers 12, converge from their supporting pivots and are arranged behind the face plate 8, with their inner or adjacent ends 125 curved or rounded and bearing against the flat adjacent end surface 703,. of head 7 b, said adjacent end of said head being transversely grooved to receive and guide the inner ends of levers 12, and to provide the elongated abutting surface 7d on which the innerends 12?), of the levers 12 can rock and slide. The front ends of retractile spring 11, are secured to the levers 12, respectively, at points between the pivoted points 12a, and the inner ends 12?), thereof, in such manner that the outward pressure of the spring against the collar 8?), of the plunger constantly tends to force the plunger outwardly with its face plate 8 at its limit of outward movement (Fig. 10) which causes the levers 12, to assume inclined positions appearing in Fig. 10. The levers 12 are em-.

angle levers or are formed with free ends 12d extending forwardly and working through the slots in the radially projecting arms of the plunger face plate or head, and'at their front free extremities provided with laterally projecting cap grasping sharp pin or needle- Y like points 120, to puncture or at least to prick and grasp the paper or like material of the ca a fkny suitable means can be provided to re= verse the position of thehead 7?) and its spindle 7 and consequently the cap carrying plunger (the plunger head 8 and its shank and the parts carried thereby) as these parts move from bottle capping position to cap supply] and from cap supply to cap delivery or bottle capping position.

As an example for this purpose, we happen to show the toothed pinion 7a, meshing with and actuated and controlled by a longitudinally slidable rack 15, having roller a, at its inner end, constantly held against relatively fixed vertically-elongated cam track 16, by retractive spring 17, so that 26" the rack is longitudinally impelled in one direction by the spring and in the opposite by the high portions or elevations of the cam track, to thereby rotate the pinion 7 a, in opposite directions and to the angular distances necessary to reverse the cap holder and carrier at the predetermined up and down portions of the travel of the carrier 2.

The track 16 is vertically elongated and in the example shown is arranged longitudinally of and suitably secured to the post or guide rod 3.

The sliding rack 15, is arranged longitudinally ofand is carried by the arm or carrier 2, and is held tostraight line re ciprocation throu h the medium of certain guideways carried hy said arm 2.

The cap carrier or transfer reversing mechanism (that embodies said cam track, the rack and pinion) is so constructed and arranged, as to present the plunger head 8,

B in horizontal position above arm 2, to the cap supply (the magazine 1) as the cap transfer approaches operative cap removing position or relation to said magazine and to maintain said position until the cap carrier on its downward movement has withdrawn a distance from said magazine. When the carrier 2, on its downward stroke has carried the cap holder down clear of the magazine, continued downward move ment of carrier 2, causes the cam track, rack and pinion to initiate reversing rotation of the spindle 80,, head 8, and parts carried thereby which rotary movement-is continued through 180 until the plunger head or plate 8 again reaches horizontal position but below carrier arm 2, and this occurs before said head 8, reaches the head of the container on which the cap is to be deposited.

The plunger 8, is in a horizontal position during the latter portion of the down stroke of the carrier 2, and also during the latter portion of the upward stroke of said carrier, and the plunger head is in efiect locked or held in horizontal positions' during said portions of the up and down strokes of the carrier 2, by the straight lengths of track 16 (see Fig. 2) through the medium of the rack, pinion, and spring 17 The plunger head 8 is reversed from its horizontal position above to its horizontal position below the carrier, about midway the length of the carrier down stroke, and about midway the length of the up stroke of the carrier, the plunger head is again reversed to assume its horizontal position above the carrier, all by reason of the inclined intermediate portion of the cam track 16, Fig. 2.

On the latter portion of the up stroke of ,the carrier, the plunger head 8 is in upper horizontal position to receive a cap, and the plunger is locked down with respect to head 7 b, by the latch 14 in looking position (see Fig. 9) for the purpose of holding the cap pricking or gripping fingers 12d swung downwardly and outwardly to withdrawn positions with their prickers 120, withdrawn from operative or cap engaging position (see Fig. 8). The cap carrying and holding parts the fingers 8c, of the plunger move up into engagement with the relatively fixed end wall of 1c, of the cap magazine and stop further upward movement of the plunger. When the plunger thus reaches its limitof upward movement, the flat top face of the plunger head 8, is centrally seated against the flat center of the downwardly protruding bottom cap of the stack of cans in the magazine tube, and intact said stack of caps is usually lifted by and upheld by said plunger head with the bottom cap centrally seated thereon midway between the two withdrawn grasping fingers 12d, the prickers 120, of which are located approximately beside the skirt of the cap (Fig.8).

When the plunger reaches its limit of up-- ward movement by reason of the fingers 8c,

abutting the magazine end Wall, the carrier 2, has not fully completed its upward stroke, but continues its relative or independent upward movement for the slight distance necessary to relieve the pressure of the spring 11, holdingthe latch 14 against the adjacent end wall of head 71) (Figs. 9 and 13) and free said latch so that under the action of its weighted arm 14a, said latch will swing outwardly to unlocking or released position. The parts otherwise will then be in positions as in Figs. 8 and 9, with the exception that the carrier 2 will be at its limit of upward movement with spring 11 fully distended, the top of the head 76, will be approximately against .are in these positions Figs. 8, 9 and 13) when pendent movement until thelower end of head 71), engages the plunger collar (Fig. 5). This independent downward 15 movement of the carrier 2 causes inward and upward swing of the gripping fingers 12d, to project to the prickers thereof into gripping engagement with or projection thereof into the skirt of the cap seated on the plunger 20 head for the purpose of radially-distorting the flexible cap skirt and grasping and holding the cap to and against the plunger head 8, on which the cap is seated, (see Figs. 1, 3, 5 and 7). The relative movement between trol the positions of the gripping fingers and to move said fingers to and from withdrawn or inoperative position and gripping or operative position under the action of the spring 11. The spring 11 not only holds the inner ends of the finger controlling lever arms 12 against the abutment floor 7 d, of the head 76 andhence yieldingly impels the fingers on their gripping strokes, but also constantly exerts plunger projecting force or tension against the plunger through the engagement of the central portion of the spring against the plunger collar 86, while the free ends of against the end 7d of head 76,- through the lever arms "12. 'The operative ends of the gripping fingers are swung toward or from each other by the relative movements between the plunger to which the levers 12-12d are fulcrumed, and the head 7 6, against which the lever end 12 are held by the spring 11.

The carrier continues on its downward stroke after the lower end of the head 7b strikes collar 8?), (Fig. 5) and thus-carries gripping fingers closing in on-the cap skirts 1 same from the contacting cap above, and on the downward movement of the plunger with skirt, aidsv the gripping fingers in stripping and from the discharge mouthof the maga- 'zinetube.

, The carrier and the plunger then move the plunger and carrier 2, is provided to con-' the springs bear in the opposite direction clown the plunger and'pulls the cap 6, seated on and gripped to the plunger head 8, from. the magazine andseparates the same fromv the caps remaining in the stack. The-two from diametrically opposite-points tend to radially and inwardly compress and distort. the cap skirt and thus raid inseparating' the the carrier, the distortion ofthe flaring cap down together below the magazine, with the flat top seated against plunger head 8, and

the flaring cap skirt extendingupwardly therefrom and grasped by the gripping fin gers. As the downward movement continues, the roller of the rack 15, travels down the intermediate inclined portion of track 16, and through rack 15, and pinion 7 a, the spin dle 7 andhead 7 b are rotated to reverse the plunger to a depending position wherein the horizontal plunger head 8, is centered above and axially over the container head to be capped with the cap in proper upright po sition held to the under face of said head and the flaring cap skirt depending. The

carrier 2 and plunger then move down to-.

gether until the cap is properly positioned on the container head, as in Figs. 2 and 10. The plunger thus reaches its limit of downward movement and presses the flat to of the cap tightly down on the top edge 0 the bottle month, while the carrier 2, continues down independently of the plunger and against'the tension of the spring 11, to swing the cap gripping fingers outwardly to withdrawn or inoperative position'and clear of the cap skirt, whereby the cap is properly H seated on the container head and released from the securing or cap grasping fingers (see Fig. 11). The carrier 2, continues on its independent downward movement for a slight distance until the latch 14, (in this example under the action of gravity) auto 'matically swings in to locking tween. the collar 86, and the a j position beacent end of head 7 b, as shown by Fig. 12. The carrier 2,

has then approximately reached its limit of downward movement, and thereupon the carrier and plunger start on theiru ward movement, the plunger being now loc ed in withdrawn position against the tension of spring 11, by latch 14. On moving up'the plunger leaves the cap pro erly seated on and covering the container ead in osition.

and readiness for securing thereon y contraction of the cap skirt under the exterior enlargement or rim of the container head, and securing in any suitable manner or by an% desirable method or means.

he carrier and the empty plunger continue on the upward stroke, and intermediate thelen th thereof, the reversal takes place to bring the plunger to position abovethe car: rier to receive and take a cap from the cap supply as.hereinbefore"descrlbed.

The. n and down reci rocations are preferably tuned with the 'ottle or, container feed to apply hood caps to the containers as rapidly as capped containers. are removed from andcontainers to be capped are brought to the cap receiving position alined with the cap supply and the vertical pathof reciprocation of the cap'transfer: p

It will be noted hat the cap transfer will not drop or deliver the cap carried thereby if it so happens that no container is at the cap receiving position when the cap carrying plunger reaches cap delivery position, but in such event the cap is retained by the plunger on the up and down strokes, until a bottle is present against which the plunger head can abut to cause the independent movement of the carrier necessary to cause with drawal of the cap grasping fingers from the cap.

The cap transfer travels in a vertical line, in this example, back and forth between the cap supply and the cap delivery point and automatically secures a cap from the supply and reverses the cap and automatically deposits the cap in proper position on the bottle head, if a bottle head is present to cause actuationof the cap release means, otherwise the cap is retained by the transfer until a bottle head or some other abutment at the cap delivery point causes the relative plunger and carrier movement to release the cap from the gripper fingers.

At the cap supply, the bottom wall of the cap magazine constitutes an abutmeint to stop the plunger and permit the relative movement of the carrier that brings about cap grasping movement of the cap gripper fin ers.

t the cap delivery point, the bottle head constitutes the abutment to stop the plunger and permit the relative movement of the carrier that brings about cap releasing movement of the gripper fingers, so that in effect, the cap transfer also constitutes a bottle finder, or a cap delivery point finder, inasmuch as an abutment or the like is needed to locatethe point at which the cap is delivered and deposited. 4

Of course, where the cap transfer delivers cup like paper articles for other purposes than bottle hood capping, a bottle head will not be used for the delivery point determining abutment, but some other means or equivalent can be utilized for this purpose.

It is believed to be obvious that various changes, modifications, and variations might be resorted to, that parts might be omitted and features might be added, all without departing from the spirit and scope of the invention, and hence we do not wish to limit ourselves to the approximate disclosure hereof.
