My invention relates to cork rod packing machines, andinore particularly toa machine of this type employing a group of circularly arranged 'reciprocatory plungers or rams adapted to act successively and progressively in relation to a sequence of tubes,

but upon succeeding charges of cork com-v position successively delivered iirmeasured quantities to each tube, until the desired volume of compacted cork composition has been'accumulated in each tube.

Heretofore in this art it has been thecommon practice in machines where plungers are [mitting the gradual step by step descentot thetube necessary to compensate. forthe in-- circularly arranged, to have the compacting plungers of progressively decreased 'or graduatedlengths to compensate for the progressively increasing volume of compacted cork composition within a' tube, as it has movement with relation 'to succeeding plungers.

In a machine embodying my present in-- 'ventlon, instead of usmg packing'plungers of graduated lengths, I employ'a sequence of v plungcr's which are of uniform length, or

i substantially so, and secure the desired variance in the effective stroke of'succeeding cessively lower the tubes toa predetermined extent to compensate for the amount of cork composition progressively accumulated therein.

tent rotarymovement to the measuring mechanism and the tube carriers is controlled. by a crank wheel mechanism for mpartlng The mechanism for imparting"intermit-i reciprocatory movement to the plungers, and i is so constructedas to secure positive movement of the tubes and of the measuring device, and to limit this movementto'that required to secure thedesired alinement of the measuring device, the openings leading therefrom and discharging into the tubes, and the tubes themselves, thus avoiding all possibility of interference by said measuring device and said tubes with the plunge-rs or securing the desired axial alinement of-these parts with the plungers.

In a machineembodying my invention, a: fairly high speed is permitted in the. ma-

chine and the lik-elihoodolt the production of imperfect rods isreduced to a minimum.

The invention consists primarily in a cork Irod packing mac'hlne embodying therein a sequence of plungers of substantially uniform length, means reciprocating-said plungers, a rotatable carrier for a plurality "oftubes whereby said tubes respectively may be brought into operative relation to succeeding plungers, supports for said plungers whereby each of said tubes will be held against downward movement with a plunger, said supports being of decreasingly graduated heights with relation'to the plungers, whereby the tubes with each actuation of said carrier will be permitted to descend from one of said supports to the other, and means for delivering a measured-quantity of cork composition to within each tube while upon each of said supports; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out a machine emin the drawings, the main frame of the ma 1 chine consists of a base 10,.having a circular formation at the top thereof and a central -tubular column 11' concentric with the'circular portion of said base. The column 11 is hollow as shown, the interior of the column being finished to permit a tubular'slide '12 torhave reoiprocatory movement therein.

Mountedwithin the base 10 is a crank wheel 13 connected by means of a pitman 14 with the piston-like slide 12, so as to impart reciprocatory movement to said slide.

and the parts carried thereby. The crank wheel 13 is driven'from any desired source of power, as the pulley driven shaft 15, the

' small gear 16 carried thereby and the internal gear 17 upon the wheel- 13. This intern al gear is preferably used to permit the utilization of the crank wheel for imparting an intermittent rotary movement to the tube carrier and the corkcomposition feeding mechanism in a manner which will be more fully referred to heremafter.

w The central column 11 has secured there to, above the base 10, a fixed cork compose tion hopper 18 of any desired capacity to permit the-continuous operation of the machine and convenience in the renewal of the supply'of the cork composition to said hopper. This hopper has associated therewith a cork composition feeding mechanism by which a measured quantity of cork will be delivered to each tube being packed, prior Y to each compacting operation of the plunger mechanism of the machine.

Rotatably mounted upon; the central column 11 is a tube carrier consisting'of a drum 19 having a sequence of circularly arranged sleeves 20 arranged in vertical alinement .with the circular top of the base 10, and the discharge port of the hopper 18,

each sleeve preferably being supported by a vertical flange 21 upon the drum 19. The

number of sleeves 20'will vary in accordance with the number of charges required to fill each tube, the operation of the machine requiring that a tube shall be moved intermittently throughout the entire circumference of the base 10 during each filling operation.

The topof the base 10 has thereon a sequence of supports 22 of gradually decreas ing heights, the highest of these supports being shown at 22 and the lowest at 22 In the forms of the invention shown, the supports 22 are a' sequence of abrupt steps, the height of each of these steps corresponding with the depth of each compacted charge in each tube.

Carried by the hopper 18, or secured to the central column 11 in any other desired manner, is a depending circular flange 23 having a sequence of stops 24; upon the lower face thereof, said stops also being of decreasing height with relation to'the plungers and to the base, the first of these stops being shown at 24 and the last 'ofthem-at 2a", the stop 24; being immediately above the support 2%, andthe stop 24 .beingimmediately above the support 22". The purpose of these stops is to check upward movement of the various tubes with theplungers.

Passing vertically through the tlange 23 and opening downwardly of the stops 24: are a sequence of channels.25 of progressively decreasing length in the direction of movement of the drum 19; Cork composition is delivered to said channels by the measuring mechanism and discharged therefrom in part by flowing under gravity, and

in part by the action of the plunger thereon, into that tube which, as the moment, is in a position to receive such cork composition from any particular channel 25. These channels are so positioned in relation to each other that they will be axially alined with the respective sleeves 20 when these sleeves come to rest after each feeding movement of the carrier. The top of each channel or passage 25 is adapted to receive corkcomposition from a measuring device receiving rotary movement with the tube carrier, this'measuring device being adapted to receive, cork compositionfrom discharge ports in the bottom'of the hopper 18, which ports preferably are elongated as shown more particularly in Fig. 3 so as to ensure. .a filling of this measuring device with the cork composition as it receives rotary movement with relation to succeeding succeeding channel's 25.

carrie'dby the drum 19, as shown more particularly'in Fig. 2 of the. drawings and the said pockets 27 are in axial alinement with the sleeves 20, k

i. The lower end of the drum 19 is outward- 1y extended as shown at 28, and Within this extended portion is a sequence of spaced,

anti-friction rollers 29 adaptedto be successively engaged by a cam about the perimeter of the crank wheel 13. This cam has a circular portion" 30 adjacent one edge of the wheel, and extending for approximately 270 in the same plan'e,a short portion 31- parallel with the portion 30, spaced away therefrom a distance substantially coinciding with the diameter ofeach anti-friction roller of the series 2-8, and a connecting oblique section 32 connecting one end of the" section 30 with one end of the section 31. The riser 32- is so positioned as to operativev lyengage an anti-friction roller of the 'se-' qluence 28 only when the conditions about tie machine are such as to permit rotation i of the drum 1 9 and the sleeves 20, and annulus 26gcarried by and rotatable with said drum; This construction is to ensure exactitude in the relative timing of the plungers', of the cork composition feeding mechanism, and of the tube holding sleeves 20.,"

yThe circular portionBO of this cam serves to maintain the carriers andthe I'neasuring mechanism ,1nj accurate ahnement With, the' various plungers upon each strokeofjthe plunger mechanism;

Carried by the top of the slide l2 top frame or spider 33, having a sequence of downwardly extending plungers or rams 34L, all of which are of substantially the same length. it It will be readily understood that precision asto the length of these 'plungers .is not essential when the material'to be worked upon is cork composition, which posse:ses sufficient resiliency to compensate for any slight variance in the lengths of dif- V-i'erent' plungers. The various plungers 34 v are respectively 1n axlal allnement w th a channel or passage 25 so'asj. to pass there-' through upon thedo'wn stroke of the plunger, and also through a pocket 27 ofthe annulus 26 which, at the time, are in axial alineme nt with thatchannel or passage, and Since the sleeves 20 are suc-' the plungers.

cessively brought into axial alinement with each channel or passage 25, and are always 3 ;ti1ne vthe short section 31 0f. the.cam 1 ipon in alinement with the same'pocket 27 it is apparent that each plun eru on each down ischarge port stroke will pass through a manate filledtube has just dropped of the hopper 18, a pocket'27, and a channel 25' into a tube3 5 carried by a sleeve 20, and during this [operation will not only assist gravity in delivering cork composition to within the tube as required,.but willco'mpact the charge of cork composition thus delivered, although upon succeeding down succeedii'ig tubes and 'not' the same tube.

, The length of each plungeri fl is such that when the pistonQlike slide 12 is in its upper-.

most position, the lower ends of the p'lu'nfgers will be positioned sufficiently above the bottom of the hopper 18' to preventcork (101 position toaccuinulate between the plunger strokes thisoperation will be in relation to and the annulus 26, in any material volume, i while at the sametnne affording ample time forthe progressive advancement of the variofus tubes to be packed or in process of v bei'iigpacked, and of the annulus' 26. The slide or spare-r33 is so-constructec'l as to possess suflicient rigidity-to avoid flexing asaresult of the resistance encountered by held against flexure by the bearings afforded by the pendant flange and-annulus 26;

"Between the supports22 -and 22? is a; re-

' cess 36, adapted to permit tubes 3 5 to drop from the sleeves 20 as thee'sleevesare progressively positioned abovesaid recess; thus aiiording clearance 'for the insertioniof a fresh, empty tube in the sleeve 20 from I The'v'arious' supportsl22 terminate in ad vance of the parallel co-operating stop's 24,

a distance slightly greater than the diarneter of the tubes, sogasto permit the tubes to: fall from the stops upon the succeeding support, following the initial rotary niove-v ment ofthe tube carriers upon each actua tion thereof. 5

' The operation of the herein 'desciiibed cork rod packing as follows:

' In startmg a run of the machine, a tube machine is substantially is inserted in each of the'sleeves 20; as it is passing above t-lierecess' 36, and held in position until the tube passes upon the support earners being sufficient clearance adjacent the stop 24: to permit the tilting of the tube when placing 'it within. said sleeve.

When'the tubes are thus inserted, the various plungers willbe toward their upper-i before granular cork isgdelivered -to the hopper 18. Upon the continuedrot'ation of the crank" wheel 13, from the position's'shownin Figs; 15 and 2, the plungers 34 will receive slight upwardmovement, an'dlat the same said crank wheel passes from engagement between succeeding wheels of the sequence 28 and the oblique section 32 by engagement with said wheels, will impart a rotary movement to the drum 19 to the various sleeves 20 carried thereby, and to the annulus 26, to an extent to bring the various pockets 27 of said annulus, and each sleeve 20, progressively into relation to succeeding plungers 34. V j

As the desired quantity of .movement of the drum 19 is completed, the section 30 engages between the succeeding wheels of the sequence 28, and holds the drum in this position, the short section 31 of said cam being thus positioned where it will enter between succeeding rollers as the rotary movement of the wheel 13 brings this section into a position where itwill'againengage said sequence of rollers.

As the annulus 26 is thus receiving movement from above one passage 25 toward the adjacent passage 25, cork will flow from the hopper 18 through the elongated discharge port of said hopper, the close fit between the top of this annulus and the bottom of the hopper preventing the escape of any cork composition except to. within the pocket. p [I As the annulus 26 and the various tubes 35 come to rest, the opening in each tube will be in vertical-alinement with a channel 7 or passage 25 and with a pocket 27, and in axial alinement with the plunger 34, cooperating with each channel 25.

When the parts are in this position, cork will flow by gravity from eachpocket 27 through each channel 25 in the flange 24, and into each tube, the quantity of this cork being determined by'the capacity of the pocket 27 although the slight distance between the plungers 34 and the top of the annulus 26, when the plungers are in their uppermost position, will tend to slightly in crease this'volume, but to a definite extent. As the crank of the wheel 13 passes the vertical center, the head or spider 33 will be moved downward slowly, so as to exert the minimum compacting pressure upon cork in the pockets27, due to a possibl sluggish action of this cork composition and a tendency of the thinly coated cork granules to adhere to the walls of the pocket.

.This downward movement, however, will assist gravity in rapidly discharging cork composition frointhe annulus to each passage 25, and therefrom to the various It will'be noted that before each down stroke of the plungers, which move as a unit, tubes in'the tube carrier will be positioned upon differentvertical planes by the supports 22, so that notwithstanding that ,the 'plungers are all, of substantially the same length, the effectiveness of theirst'roke in compacting thecork, is controlled by the positionof the several tubes. Hence, when the first charge of cork is delivered to the various tubes, the only charge which will be compacted is that which is in the tube 35 seated upon the support 22 and that all tubesin advance of this tube will'be imperfectly filled and packed duringthe ini tial cycle of operations of the machine. When the machine, however, has completed this initial cycle, this filled .tube' will be discharged from the machine, and thetubes that I pass through the machine following this particular tube will also be completely filled and packed, so that thereafter. each actuation of the carrier will deliver one 'con'ipletely filled and packed tube as a result of the progressive action of the successive plungers 34.

The condition; of packing is illustrated l diagrami'natically in Fig. 40f the drawings, which shows the position of each tubein a tendency, by reasonof frictional engage ment between the plunger and the tube, to raise the tube, which necessitates the employment of the stops 24. By staggering the stops 24 in relationto the'supports 22, however, clearance is afforded for an initial movement of the tube supports following the escape of the plunger from within the tube, to permit the tubes to descend by gravity to the'succeeding support 22 Without interference from the vertical fall between succeeding stops.

Following each up stroke of the plunger 34, the cams 30, 31 and 32 will impart the desired fixed quantity of rotary movement to the sleeves 20. and the annulus '26, the

section 30 preventing any possible overrunning of the drum 19 and the parts carried length facilitates uniformity in the actuation of the cork composition feeding mechanism, and secures a well balanced condition in theplunger mechanism. At the same time, all plungers will. pass through the pockets 2? simultaneously, 'so that-there are uniform pressure conditions as to all of the plungers upon each down stroke thereof.

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it be:

' ing apparent that such details are subject A to 'wide variation, while still preservingithe essential characteristic of the invention,

which resides in the sequence of plungers of substantially uniform length, and that arrangement by which the tubes, after having each chargeco-mpactedtherein, are caused" to descend to a lower level in relation to'the plunger and to an extent approximating the height of a compacted charge of cork;
