The principles and features of the present invention are shown in the drawings as embodied in a mechanism particularly adapted for use in feeding and serving or applying skirted caps or closures which may be of paper, fiber or other principles and features herein indicated, the invention being susceptible of use with any mechanism where it is desired to selectively or periodically feed and deliver closures, and that'the embodiment herein shown and described, is illustrative only of one use to which this invention may be utilized.

Referring to the drawings in detail, particularly to Figure I, the device of my invention A is shown in association with a milk bottle conveying mechanism B for use with a closure sealing machine. The device ofthe invention is preferably constructed as a portable and adjustable unitary structure including a multiple closure retaining means or magazines I8 and I I, a clo-' sure feeding or withdrawingnnechanism located within the cover or guard I2 and a closure serving device I4. The latter adapted to apply the closures to the milk bottle II moved by the conveyor B.

Carried on a pedestal or frame member 2I secured to the top of a vertically movable standard or post 22 'as an adjustable unitary structure are the magazines for retaining independent supplies of closures 28, the feeding mechanism, the serving chute and associated instrumentalities of the invention. The post 22 which is preferably of a hollow cylindrical configuration closed at its upper end and having means therein for adjusting the unitary structure of the invention disclosed in Patent #2,304,146.

The arm or ledge 48 preferably forming an integral part of frame 2I fixedly supports a bracket 4| of triangular configuration carrying on its inclined surface 42 the base member or casting 44 of Y-formation and of channel shaped cross section forming a component element of the cap delivery chute I4. n the upper surface of each of the arms 48 and 41 of member 44 rest the cap retaining means I8 and II in inclined relation, clearly shown in Figures I, II, and III of the drawings.

The magazines I8 and II are particularly illustrated in Figures I, II, III, VI and VII wherein it can be seen that they are similar in construction each comprising a channel shaped member or retaining chute 48 having their web section of V-shaped formation with their side walls substantially parallel. The lowerextremity of each of the channel members 48 is supported by irregularshaped sleeve-like members 49 the base of which is fixedly secured to the upper surface of the arms 46 and 41. The sleeves 48 are provided with an outwardly projecting flange 5| upon which are fixed in spaced relation a plurality of resilient fingers 52 by means of clamps 54 held in place by screws 55, clearly shown in Figure VIII. The fingers 52 project inwardly through suitable slots 56 formed in the channel shaped members 48 their ends flaring inwardly and having serrated extremities adapted to engage the caps or closures in each of the channel members 48. Each of the resilient fingers 52 is provided at its intermediate portion with a hook-like member or finger stop 59 adapted to project outwardly through the slots 56.

The tension or inherent fiexure in the fingers 52 serves to urge them to their innermost position toward the axis of movement of the caps 28, the inward movement of the fingers being limited by means of an adjustable camming ring-like member 62 carried on the outer surface of the sleeve 49 which is in engagement with the finger stops 59. To adjust the innermost movement of the fingers 52 it is only necessary to rotate the the camming member 82 to urge the fingers outwardly through the medium of hook-like members 88 in contact therewith so as to change their relative position within the members 48.

6 The caps designated 28 are positioned in nested formation as particularly illustrated in Figures VI and VII, the uppermost cap being engaged by a Weight preferably of cylindrical configuration having a guidingmember engaging the edges of 1 the channel member 48 to prevent rotation of the caps 28, but serving to force the caps downwardly into engagement with the cap withdrawing or feeding mechanism.

Each of the sleeve-like members 48 has assoelated therewith a pair of closure supporting arms 33. Channel members 48 and members 48 as shown in Figures VI and VII, each having a pair of slots 58 arranged vertically at opposite sides thereof, and within said slots are pivotally 2 secured to the side walls of member 48 the arms 33. The lower ends I28 of each of the arms 33 are bent inwardly and are also forced inwardly by means of fiat springs 88. The upper end of each of said springs being secured to member 48.

The free or lower ends of each of said springs 88 are in contact with the lower ends I 28 of arms 33 forcing said lower ends I23 into contact with the lowermost closure of the closures 28 nested within members 48. The upper ends I29 of each 30 of the arms 33 are normally positioned within the slots 58, this being clearly shown in Figure VI. Whenever a closure is withdrawn from the magazines I8 and II by members II or I3, the closure being withdrawn forces the lower ends 35 I 28 of said arms outwardly against the tension of said'springs 88, and at the same time the upper ends I29 pivot inwardly, as shown in Figure VII, and interrupts the downward movement of all the closures 28, arranged in the magazines and 40 positioned above said arm ends I28. Substantially the entire weight of all the closures 28 in said magazines I8 and is absorbed by arms 33 as only approximately 10 closures remain in each member 48 below said arms when the lowermost closure is being extracted by the vacuum closure transporting members. Eliminating the weight of the closures nested in the magazines provides a more eflicient manner of extracting the lowermost closure nested in each member-48.

I have provided novel and effective mechanism for periodically and simultaneously withdrawing caps from the magazines I8 and II to be concurrently deposited in the upper portions 48 and 41 of the inclined serving chute I4. Operable means which will be described below in detail are provided in the upper portion of said chute to temporarily restrain or arrest the movement of one of said caps.

The closure withdrawing mechanism is particularly shown in Figures IV, V, VI, and VII, of the drawings, and comprises a rectangular shaped housing 65 supported on the inclined surface 43 of bracket H and which is adapted to receive for movement therein a reciprocable member or slide bar having a pair of inter-connected spacedhollow plungers 68 and 18 which projects through the upper wall of the housing 65. The plungers 68 and I8 are in axial alignment with the magazines I8 and II carrying at their ends suitable fittings for removably supporting conically or cup shaped hollow flexible members II and I3 adapted to engage the caps 28, said flexible members preferably constructed of rubber or other suitable distortable material. Each of the cup-shaped members, in cooperation with the hollow plungers, is in communication with a connected central passage provided in passing through said conduit 82, the top of said jar having an outlet 85 connected with a conduit 86 for the clean air, said conduit 86 in turn connects with a hollow member positioned adjacent arm portions 46 and 41 of serving chute I4, and having associated therewith discharge nozzles. The air being discharged from the nozzles acting as a means to force downwardly all caps retained by friction or otherwise in the upper part of the serving chute.

The slide bar carrying the pair of hollow plungers 68 and I is provided adjacent to its lower extremity with suitable actuating means and which'is journalled to the.lower end 94 of the pitman or connecting link 95, said means travelling in elongated opening 92 formed in the side wall of the housing 65. The upper end 98 of pitman 95 carries a suitable bearing journalled upon a crank pin which is fixedly carried on the eccentrically located boss ml of the rotable cam member I02.

The cam I02 is associated with one end of the shaft I05 by being fixedly secured to a sleeve I 01, said sleeve being keyed to shaft I05 by key I08. The shaft I05 forms part of a suitable gear reduction mechanism I09 directly connected at one end of the-shaft of the electric motor IIO constituting the common source of power for the vacuum pump 80 and reciprocating member or slide bar and cap withdrawing means carried thereby.

Referring to Figure IV, it can be seen that the peripheral surface III of the timing cam I02 coacts with the cam engaging roller II4 carried at one end of arm II6 fixed at its other end III to the transversely extending shaft I I8, the latter, journalled on bearings provided on the uprights H9 and I20 carried by the casting 44 of the receiving chute I4. The cam roller H4 is urged into contact with the cam surface III by means of a retractible spring I22 connected to the arm 45 which in turn is connected to arm II6 by link 63.

The shaft II8 fixedly carries adjacent to upright II9 the end I24 of arm I25 the other end of which is formed with an elongated opening I2'I adapted to accommodate the valve stem of I28 of the communicating valve mechanism I6 which operates to control the vacuum connection between the inlet port I8 of the vacuum pump 80 through the conduits I4 and I1 and passageways to the flexible cap engaging members II and I3.

I have provided means to cause the lowermost cap of each of the magazines I0 and II to simultaneously adhere to the flexible cup members II and I3 when the same are in the uppermost position that is, the position shown in Figures V and VI so that when a downward movement is imparted -to the cup members by the crank arm 95, the caps will be carried past the fingers 52 g and simultaneously deposited on each of the arms 46 and 41 of the serving chute I4. To this end the suction side of the pump 60 to produce a normally reduced pressure is communicated to the flexible members 'II and I3 when the same take theuppennost position. Therefore, said members produce a partial vacuum between the cup members II and I3 and surface of the caps engaged thereby causing the caps to forcibly adhere to the flexible members so that when the latter are moved downwardly the caps will be carried past the fingers 52 to a position where the lowermost portion of the caps will engage the inner surfaces I30 and/or -I3I of each of the arms 46 and 41, atmospheric pressure is admitted so that the partial vacuum in the members II and I3 is simultaneously raised to atmospheric pressure, the equalization of pressure and inclination of the arms 46 and 41 will produce an automatic release or disengagement of the caps from the flexible members II and I3 depositing the caps concurrently upon said surfaces I30 and I3I of each of the members 46 and 41 of the serving chute I4.

ing member I6 carried by the transversely ex tending shaft H, the latter journalled on bearings provided on the uprights I8 and I9 supported above arm 46. One end or shaft II has secured thereto a gear I3. Said gear I3 meshing with a rack-type gear 28 forming an integral part of one end of arm 3I, th opposite end of arm 3I having a suitable bearing associated therewith and carried at one end of shaft I I8. Said arm 3I having secured thereto a downwardly extending arm member 45, having a cam roller 50 joumalled on the free end thereof. Said cam roller 50 coacts with a cam 53 forming an integral part of sleeve I01. Between downwardly extending arms 45 and H6 is provided a link 63. Said link 63 provided with an open passageway 64 in one end portion thereof, said passage 64 coacting with bolt 66 secured to arm 45. The opposite end of link 63 is journalled to arm II6. Spring I22 is suitably connected at oneend to the lower side of the upper end of arm 46, while the opposite end is connected to arm 45, said retractable spring urging said roller 50 into contact with cam 53, and at the same time urging roller H4 in contact with surface II I- of cam I02 throughout the movements of both the cams 53 and I02 due to link 63 having lost motion means in the form of .a slot 64 being-associated with belt 66. Said retaining cap positioned in arm 46 is released only after plunger 68 carrying flexible member II has reached substantially its lowermost position, and the cap released in arm 41 has entered its proper position in cap chute I4. By this novel means the caps are guided and moved in proper alternate sequence to the single outlet conduit I40 and hence to the point of application or serving outlet I42 for application to the mouths of the bottles or containers I5.

The means to effect the proper application of the cap from the single serving outlet I42 to the mouth of the bottles I5 is particularly shown in the lower extremity of a serving outlet I42 is enlarged and the side walls pivotally carry as at I45 a d I48 the wing-like members I41 and I40, each having curved portions III which are adapted to engage the neck portion of the bottle I5 as the same passes under the cap applying outlet. The wing-like members I41 and I48 are preferably held in their innermost position by a suitable coil spring I52, the ends of which are suitably secured to post I54 and I58 carried by each of the wing-like members. The spring I52 serves to urge the wing-like members into contact with the skirt of the bottle caps but permits a release when the same are engaged by the moving bottles.

I have provided means whereby the simultaneous withdrawing of the caps from the magazines I and II and the simultaneous delivery to the serving arms 48 and 41 will be interrupted when there is a predetermined number of caps in the serving chute I4 arising by reason of the fact that the number of bottles I5 travelling on the conveyor B are insuflicient in number to withdraw the caps fed into the sewing outlet I 42 as rapidly as the feeding mechanism normally transfers the caps to the arms 48 and 41. To this end the application of a partial vacuum or a normally reduced pressure to the flexible cups 1| and 13 is interrupted or rendered inoperative through the medium of a cap contacting pad I adiustably supported upon the end of the arm I12 having its end I13 fixedly secured to the shaft H8. The pad I10 is adapted to project through a suitable opening I15 formed on the cover I16 which closes the channeLshaped conduit or serving outlet I42. As hereinbefore pointed out, the shaft II8 carries the valve operating arm I25 which is connected to the valve stem I28 of the valve mechanism 16 which establishes a connection between the suction side of the pump 30 through the flexible conduit 14 to the flexible members H and 13 when the same are in their uppermost position.

As illustrated in Figure VII when the conduit I42 is filled with caps- 20 so as to cause the pad I10 to engage the upper surface of one of the caps retained therein, the valve. control lever I through the adjustable stop or threaded nut will operate the valve stem I28 to'its opening position so as to render the connection between the vacuum pump 80 and the flexible members H and "ineffective; The valve mechanism which controls the connection for the application of a partial vacuum or a normally reduced pressure compared with the atmosphere to flexible cups H and 13 may be of any suitable type, preferably of a type wherein the valve is actuated by a valve stem, the: valvehaving one position in which a connection is established between the flexible tube 14 and the conduit 11 connected to the suction side of the pump 80 and wherein said valve is moved by its valve stem to another position to render said connection ineffective such as by by-passing or venting to the atmosphere conduit 11 and flexible tube 14. A preferred form of the valve mechanism of this type is illustrated in detail in the copending application referred to supra. For the purpose of th present invention the general elements of the valve mechanism are illustrated and include the valve chamber or hollow housing 18 to which are connected the flexible tube 14 and the conduit 11. The tube 14'and conduit 11 are normally interconnected by a valve contained within the housing 18 which is in turn actuated by the valve stem I28. The arrangement is such that when the arm I25 moves the valve stem I28 outwardly through the adjustable stop carried thereby the valve head renders the interconnection of conduits 14 and 18 ineffective venting the same to the atmosphere through a suitable opening provided in the hollow housing 18 so that no communication is established between the suction side of pump 80 and the flexible members H and 13.

In the embodiment of the invention illustrated, the means to produce a source of normally reduced pressure creating a partial vacuum as compared with atmospheric pressure for rendering by its application the cap withdrawing means efiective is in the form of a constantly ctuated suction pump 80 carried by the frame 2| which is rotated through a suitable gearing not shown, the latter connected to the shaft of the electric motor II 0 which also operates the reciprocating carrier or slide bar 86 of the cap withdrawing mechanism; However, it is to be understood that any suitable pneumatic means operable to cause the hoodcaps 20 to forcibly adhere to the suction cups H and 13 is contemplated.

Means are provided to retain the mouths as well as the necks of the bottles sanitary and prevent germ contamination prior to the application of a hood cap to the mouth of bottles that have been filled and disc capped. These means are located in spaced relation to the serving chute delivery. outlet so that their operation is performed during the transfer of the bottles to the serving outlet by the conveyor mechanism and includes a spray nozzle or wash unit I35 which serves for spraying and washing the mouth and neck of the bottle in association with means to accelerate the drying operation by blowing heated air thereto through the use of a blower motor I31 provided with suitable heater coils having spaced outlets located in the bottom of member I 38. The blower motor I31 and the wash unit I35 are suitably supported on the lower surface of the arm 40 so that the same are moved concurrently with the magazines, feeder mechanism and cap serving chute when movement is imparted to the post 22.

I have provided a control or switching mechanism I03 and I04 for closing and opening the circuits of the motor IIO. I have provided a switch I 08 for closing and opening the circuits of the blower motor I31 as well as the heater coils associated therewith. The actuation of the switch mechanisms I03, I04 and I08 by the operator -t'o a position to close the circuits will start the'electric motors H0 and I31 so that each of the bottles already fllled and disc capped which are moved by the conveying mechanism toward the serving chute I4 is prior to the engagement of the mouth of the bottle with the wing-like members or fingers I 41 and I49 successively sprayed by the water nozzle I35 and dried by blowing air thereto through the blower motor outlets in member I38. Movement of the conveyor mechanism B will carry the bottle past the blower motor outlets to a position wherein the forward upper portion of the bottle mouth will engage the inner surface of the skirt or depending portion of the hood cap 20, forward movement of the bottle will'carry the hood cap past the wing-like members I41 and I 49 causing the horizontal portion II3 of the leveling finger II 2 to press the upper flat portion of the hood cap over the bottle mouth thus completing the cap applyin operation. It is to be understood that the motor I I is constantly actuating the vacuum producing pump 80 and reciprocating the suction cups II and I3 through the carrier or slide bar 06 and the pitman 95 eccentrically connected to the timing cam I02 which is rotated through the gear reduction mechanism I09 directly connected to one end of the shaft of the electric motor IIO, so that when a hood cap is withdrawn by a bottle passing beneath the serving outlet the hood caps in the serving conduit I42 gradually slide downwardly. The downward movement of the caps will allow the pad I10 carried by the arm I12 fixed to the shaft IIB to gradually move downwardly between the caps. The downward movement of the pad H0 is caused by the rotative action, imparted to the shaft I I8 by the arm IIG fixed thereto, produced by the spring I22 when the roller II4 contacts the dwell of the cam I02. The shaft I I8 will also move the valve timing arm I25 to allow the valve stem I28 to in turn operate suitable means contained within the communicating valve mechanism I6 thus con- 66 reciprocated by the pitman 95 connected to pin I00 is in its uppermost position as particularly illustrated in Figure V, at which time there is a registration between the valve mechanism to the source of reduced pressure 00 so that when the suction cups II and 13 contact with the lower face of the hood cap next to be delivered and held by the resilient fingers 52, a reduced pressure is applied to the hood cap by the communication set up by the valve mechanism between the source of normally reduced pressure 80 and the" suction cups II and I3 which will cause the low-- ermost hood cap of each stack to forcibly adhere to the suction cups producing an extracting en- 'gagement. This extracting engagement will serve to carry the hood caps in the downward movement or withdrawing stroke of the carrier 66 past the serrated portions of the fingers 52 to a position where the lower edge of the skirt portion is in engagement with the wall sections ad- :Iacent to the openings on the base of the receiving chute through which the suction cups are moved in their reciprocating movement. It is clearly understood that each of the openings on the base plate of the arms 48 and 41 is of suitable dimension to allow the passage of the suction cups II and I3 but smaller than the diameter of the skirt of the hood caps 20 so that their lowermost edge is engaged by the surfaces of the base plate of the serving chute. adjacent to the openings before the carrier 66 approaches substantially the end of its withdrawing stroke. The

base plate of the receiving chute is so arranged that when engagement of the skirt of the hood caps take place with said surfaces, air is admitted by operable means so that a partial vacuum in the suction cups II and I3 simultaneously rises to atmospheric pressure. Equalization of pressure and the engagement of the lowermost portion of the cap with the receiving surface of each of the arms 46 and 41 will cause the simultaneous disengagement of the hood caps from the suction cups and the simultaneous deposition of the hood caps in each of the arms 40 and 41. As hereinbefore pointed out, the cap in the an gular displaced arm 41 travels freely to theserving chute I4 while the cap deposited in arm 46 is retained or retarded temporarily by member I6 so as to allow the caps to enter the serving chute I4 in proper alternate sequence.-

The foregoing operation is accomplished during the normal cycle. However, when no withdrawal of the caps takes place due to the fact that a bottle has not'been moved past the serving chute I4, the caps in the conduit I42 will remain stationary and the pad 0 will contact the upper surface of a hood cap, under the combined action of dam urging roller I22 and mechanism associated with valve I8, thus preventing the cam roller II4 from engaging the cam dwell of said cam I02 causing the valve mechanism I6 to function in a manner providing an opening to the atmosphere so that no communication is established between the suction side of pump 80 and the flexible members I I- and 13. Therefore, when the slide bar 66 reaches its upper position to cause cups II and I3 to engage the lowermost hood cap there is no application of a reduced pressure and consequently no extracting engagement between the suction cups and the hood caps to overcome the action of the resilient'fingers 52. In this manner the withdrawing means are rendered ineffective to transport simultaneously a hood cap from each of the magazines I0 and II to the serving chute arms 40 and 41.

As shown in Figure .1, means are provided to enclose the cap withdrawing and transporting mechanism in the form of a cover I2 as well as suitable means to cause the lubrication of the parts and to collect excess oil and grease so as to insure the smooth running of the mechanism preventing .the possibility of oil or other foreign matter to accidentally fall on the bottles or on the hood caps. In addition, it should be noted that due to the particular correlation and coordination of the number of magazines or cap retaming means with the simultaneously actuated I cap withdrawing elements, and the member I6 'disposed in arms 40 for temporarily restricting the movement of one of said caps, I have materially simplified the loading of the retaining means I0 and II by the operator as the caps will be exhausted at the same time in each magazine so that the simultaneous loading of the magazines can be efiected by the operator.

It is apparent that, within the scope of the invention, modificationsand difierent arrangements may be made other than is herein dls closed, and the present disclosure is illustrative merely, the invention comprehending all variations'thereof. 1
