5' It is customary to pack various products,

particularly food products, in packages or cans and close them by means of closure caps. The more desirable types of containers are frangible vessels such as glasses, jars, and

w. the like, although many types of tin cans are in use. The products are placed in these receptacles and in some instances hermetically sealed by soldering a cover thereon, or in the case of glass containers by the compression of a suitable gasket. Frequently hermetic seals are not required but seals commonly known as friction seals may be utilized. In all cases however, closure caps must -be placed upon the tops of the containers prior to the subsequent sealing operation, if any. Since packages of these general types are sold inlarge quantities due to the fact that they are household necessities in every home, it is highly important that each step in the manufacture be as economical as possible.

Skilled operators have been utilized for applying caps to containers as they pass along aconveyor at a definite rate but the handling of each individualcap is likely to contaminate it rendering the contents unsanitary. The cost of manual application too, is extremely high. Machines have'been provided for applying caps to certain types of vessels but are objectionable in that they re quire the feeding of individual caps into chutes whichagain necessitates constant attention of an operator and His handling of the individual caps. The moving parts of the machine for applying the caps to the containers must be ad usted to a high degree of ac curacy requiring complicated constructions necessitating frequent attention to maintain the correct synchronism, and endangering the vessels and contents in the event that the adjustments are not accurate.

The present invention overcomes these dif ficulties" by providing a machine adapted to receive a stack of caps which may be removed groups from thecartons in which they are shipped and suflicient'quantities mounted in CITY, NEW YORK, A CORPORATION or PACKAGE ASS EMBLING MACHINE 1926. Serial No. 122,516.

the machine to permit it to run for considerable periods 0 time. The individual caps are removed from the bottom of the stack automatically and fed mechanically in timed relation to the presentation of vessels to a depending support and held in that osition to engage an approaching vessel and he applied thereto as it moves under the support. The feeding of the ca -is actuated by the vessel on which it is to e applied, and hence the feeding mechanism is always in synchronism with the presentation of the vessels. F urther if the vessels are .fed irregularly to the conveyor the proper feeding of the caps is not affected. Derangement of the vessels is prevented by providing a ratchet connection which is adapted to permit the vessels to pass without feedin caps when a predetermined resistance is o ered to the displacement of a cap from the lower portion of the stack.

An object of the invention is to provide a simple and effective machine for placing closure caps upon moving vessels at a high rate of speed without manipulating the vessels or disturbing their rate of movement.

the cap adjacent the bottom cap and raising the entire stack free of said bottom cap so that it may be removed without difliculty.

Another object of the invention is to provide an inexpensive cap feeding device adapted to remove a single cap from a stack and place it in position for engagement with the'rim of a vessel. q

, A further object of the invention is to provide cap feeding means actuated by the passing vessels whereby caps will not be fed unless a vessel is in position to receive it and to. provide in addition suitable safety devices to prevent derangement of said vessels in the event a predetermined resistance is ofleredtothe operation of the cap-feed. v

A still further object of the invention is to effect rapidand accurateassembling of closures onvessels and complete seating thereon while they are being fed or moved progressively.

Other and fu' the invention other than those hereinafter 's ecificially referred to will occur to one s 'llcd in the art or become evident upon the employment of the invention in practice.

Described generally, the above objects are attained in this embodiment by utilizing a conveyor for moving vessels at a predetermined rate under a cap support having a depending, inclined portion adapted to hold a cap extending over the lower portion thereof in canted position to engage the rim of the 'container and be removed therefrom. The closure caps are preferably placed in a stack on the support and suitable reciprocating fingers are utilized'to engage the stack of caps and raise it clear of the bottom cap thereon so that the bottom cap may be moved to position on the support, Suitable positioning devices are adapted to be operated by the moving vessels to position the cap separated from the stack as the vessel is presented to engage the cap. The cap positioning member is driven by means of a ratchet mechanism which is adapted to operate when a predetermined resistance is offered to the movement of the cap positioning member so that the vessels will not be deranged or overturned in any instance. The entire device is adapted to be adjusted for various sizes of vessels so that it may be changed quickly to accommodate any type of vessel, 7

A preferred embodiment of the invention has been chosen for purposes of illustration and description and is shown in the accompanying drawings, wherein Fig. 1 is a. perspective view illustrating the operation of the machine; v Fig. 2 is a side elevational view of the machine;

Fig. 5 is a sectional view along the line 5-5 of Fig. 4;

Fig. 6' is a sectional view illustrating the mechanism of Fig. 5 prior to the engagement of the fingers with the caps; and

Fig. 7 is a detailed view illustrating the application of a cap to a vessel.

Referring to the drawings, there is shown a conveyor 10 of any suitable type having bars 11 adapted to move the vessels 12 under the support 14. An upright channel member 16 is mounted on the framework 17 adjacent the conveyor for the adjustable attachment of various parts of the mechanism thereto.

A shaft 18 is threaded through the upper end of the upper right member 16 to extend longitudinally of the channel with a knob 19 at its upper end for rotation thereof. A suitable block 20 is s lidably mounted in the channel and threaded to the shaft 18 for vertical movement therein and may be securely held in any desired position by bolts 22 threaded into suitable projections 24 on the back of the block and adapted to slide in a suitable slot in the upright member. The position of the block may be adjusted by loosening these bolts and rotating the shaft 18. Suitable lateral flanges 26 are provided on the block with a horizontal groove therein adapted to receive a corresponding tongue on the support 14 to form a dove-tail joint 28 therewith. Bolts 27 may be inserted through the apertures in the flanges and threaded to the support, rigidly to hold it in adjustable position.

The support 14 is here shown as a casting having an aperture or recess 30 with four ods 31' mounted thereabout to receive a stack of caps 32. The bottom of the aperture is closed by a plate 34 suitably bolted to the support and having an arcuate slot 35 to accommodate a cap positioning member adapted to move the cap ,at the bottom of the stack along the plate. The support 14 and likewise the plate 34, mounted on the lower side thereof, have an inclined depending portion 36 on which the cap positioning member moves the caps prior to their engagement with the vessels. At the lower end of the depending portion of the plate 34, a recess 38, preferably circular in form, is provided through which the rims of the vessels on the conveyor move whenthe support is properly adjusted. Individual caps 32 are moved on to this as described hereinafter and held in position by a holding member 40 rotatably mounted on the webs 42 on the support 14 by means of the pin 41. As a cap moves on to the depending seat it engages and raises a member 45, having a flat portion 46 bent substantially parallel to the inclined portion of the plate34. The member 45 is adapted to rotate about a pin 47 and is held in its normal position by means of a set screw 48 which may be adjusted to hold the cap in its proper position without oflering sufiicient resistance to its movement to interfere with the proper operation of the machine. The lower edge of the cap engages the member 40 and is resiliently held from further movement until a vessel 12 passes through the recess in the plate 34 and engages with its rim the skirt of the cap and presses the holding member 40 from its normal position. As the vessel continues to move the cover; is raised and removed from the inclined support, the member 40 pressing the skirt of the cap firmlyagainst the rim of the vessel and then riding over the flat cover portion to press the cap properly on the vessel.

To separate the caps from the stack and to move them individually to the vessel. engaging position on the depending support, there is provided a pair of shafts 50 mounted in extensions 51 on the support 14 which are provided with oil ducts for the proper lubricationof the bearings. Sleeves 54 are mounted on the shafts havingjpairs of depending arms 55 thereon slotted at 56 to receive cap engaging fingers 57. The slots 56 are slightly widerthan the fingers to permit slight play therein when pivoted by bolts 59 so that they may find their proper place between the bottom cap and the one adjacent thereto for raising the stack of caps. The ends of the fingers are bevelled from the respective sides in a vertical direction to form wedges 58 curved at their extremities into substantially the shape of the caps whereby,

when the pairs of fingers 57 are moved toward each other,'the stack of caps is firmly supported at four points.

For the proper operation of the fingers 57 there are provided arms60 and 61 keyed to the ends of the shafts 50, with one of the arms extended beyond its sh aft with its end in the form of a collar 62 adapted to receive a rod 64. The inner ends of the arms are slidablv connected to permit oscillation thereof. The rod 64 has its end threaded for a substantial distance with suitable nuts 65, and look nuts 66 mounted on the respective sides of the collar 62 to hold it in proper position. The lower end of the rod is slidably mounted in a bearing 67 in the framework of the machine with a suitable spring 68, held in position by a collar 69 and nuts 70 on the rod to holdthe rod resiliently in its upper position and to maintain the fingers out of contact with the stack of caps.

A lever 72 pivoted to the framework of the machine at 74 is attached at one end to the lower end of the rod 64 and has a cam roller 75 at its other end in engagement with a cam 76 on a drive shaft 77. The drive shaft 77 preferably is operatively connected to the conveyor drive so that it may be timed with respect to the movement of the vessels. This permits periodic operation of the fingers 57 for raising the stack of caps to free the lowermost cap thereof as the respective vessels ass. p The individual caps are removed and fed to the depending part of the support by means bushing 91 on the lower end of the shaft and ease in the eventthat the upper turnstile 81 is prevented from rotating by any ob'stacle.- The spring 95 is adjusted so that the lower turnstile may be readily rotated by the vessel without derangement thereof in opposition to the ratchet mechanism.

Suitable adjustable guides 97 are provided to extend over the sides of the conveyor adjacent the lower portions of the vessels to guide them properly'thereon. More accurate adjustment of the lateral position of the vessels is attained by means of curved guides 98 adjustably mounted on the bottom of the plate 34 whereby the vessels, as they move along the conveyor, are if necessary, moved slightly in either direction to engage the center of a cap 32 depending over the lower portion of the plate 34. p

In operation, the cap applying mechanism is mounted over a suitable conveyor 10, which may lead to a sealing machine or elsewhere. As the vessels pass under the support 14, the cam 76 through lever 72, rod 64, arms 60 and 61 and shafts 50, oscillates the fingers 57 into engagement with the under side of the cap adjacent the cap at the bottom of the stack to raise the entire stack free from the lower-, most cap therein. At this time 'avessel 12 engages the lower turnstile and rotates through the ratchet 93 and shaft 82 the upper into engagement with the member 40 which holds it in canted position at the end of the support. At this time the cap is -mounted above the recess 38 anda substantial part of the cap is presented to the vessel 12 as it passes through the recess so that the rim of the vessel engages the skirt of the cap and raises it from its canted position off of the support and at the same time the cap is pressed downwardly on the vessel'by means of the member 40. After the cap freed by the fingers 57 is removed from the stack, the cam 76 permits the spring 68 to retractthe fingers 57 and permit the stack of caps to rest on the plate 34. As successive vessels are presented this cycle of operation is repeated, and if at any time the upper turnstile is prevented from moving by reason of the failure of the fingers to free the lowermost cap of the stack 7 or for any other reason, the ratchet mechanism 93 operates to permit the lower turnstile or lowered as shown respectively in Figs. 3

and 5 to accommodate vessels of any height. The adjustments as to height may be made by loosening the-bolts 22 in the uprightmember 16 and if the support is to be raised by moving upwardly the nuts 65 and 66 above I the collar .62 on the shaft 64,.and by likewise moving upwardly the collar 85 on shaft 82.

Then by rotating the threaded shaft 18 the blo k 20 and the support 14' may be raised to t e desired position. The lower nuts and 66 adjacent the collar 62 and rod 64 are then properly positioned to lock the collar in its proper position and likewise the collars 85 and 86 are positioned to lock the upper turnstile in proper position.

It. will be seen that the above invention is readily applicable to all types of sealing machines and may be readily mounted upon any conveyor to apply various types of caps to vessels and receptacles without interrupting the movement thereof. Further, the machine is of simple and inexpensive construction and the parts are fully capable of withstanding the rceugh usage to which they may be sub- 'e'cte 1 While the particular embodiment described above is designed primarily for use in association with a sealing machine which is effec.- .tlve on the closures after they have been assembled on the vessel in order to form a seal between the closure and the vessel, it is obvious that the invention is not limited to such an embodiment and that various changes may be made in the construction and application described herein without departing from the spirit of the invention and the above description is, therefore, to be taken as illustrative and not in a limiting sense.
