Application filed December 1, 1923. Serial No. 678,032.

The invention relates to new and useful improvements in jar closing machines, and mere particularly a jar closing machine wherein the jars pass continuously and in succession through the machine, and wherein the securingmeans operates to secure a metal cap to a without stopping the movement ot the jar. By the term cap is included jar bands and other forms of closures having a depending flange.

jin object of the invention is to provide a machine et the above type wherein the 'liauge of the metal cap is turned underf neath a ledge at the mouth of the jar by means ot a stationary member with which the cap maires rolling contact,r and wherein the initial inturning of the lower edge oi the vflange accomplished by positive means while the final inturning of the flange and the sealing of the cap on vthe jar is accomipilished by yielding means.

A further object of the invention is to provide a machine of' the above type with traveling means for holding the cap in con "-1 tact with the member which re-shapes the flange. which traveling means is formed so as to yield under excessive pressure.

i still further obiect of the invention is to provide a machine of the above type which so constructed that the jar is supported by the ledge at the mouth of the jar during the sealing of the cap to the jar.

il further object of the invention is to provide a machine oit t-he above type with means located at the entrance end of the machine for insuring the preliminary seating of the metal cap on the jar as it enters nie jar closing machine.

'turther object ot the invention is to provide a machine or the above Atype which may be readily adjusted for jars of differn ent heights. and caps of different diameters.

The machine embodying the present invention is an improvement upon the jar closing machine shown in my prior Patent No. 1,495,650, dated May 27, 1924.

The machine is especiallyT adapted 'for attaching metal caps, such as a metal jar band cap, to the mouth of a glass jar. The jar has a ledge at its mouth and the cap is secured thereto by turning the lower portion of the flange ony the cap underneath the ledge. The jars with the caps loosely resting thereon are brought to the machine by an endless conveyor. Just before the jars enter the machine a traveling pressure means engages the jarcap and insures that the ca-p is properly seated on the The machine includes two parallel spaced menibers, one of which is stationary,l while the other is movable. Thev movable means operates to convey the jar through the inachine and to roll the cap flangey along the stationary member. The stationary meinber is so constructed as to turn the liange ot the cap underneath the ledge on the The stationary member and the movable member are further so constructed as to support the ar from the ledge at the mouth et' the jar. rlhe stationary member at its entrance end has co-operating members held in fixed relation to each other which operate to inturn the flange of the cap underneath the ledge on the cap to a certain extent. The face of this member which engages the lower edge of the flange is provided with vtransverse ribs which operate to corrugate or break the extreme edge of the flange lo assist in the inturning of the flange underneath the ledge. The remainder of the stationary closing` means has co-operating parts Which yield relative to each other and these con'iplete the inturning of the flange underneath the ledge on the jar. lnasmuch they yield any liability of crushing the jar at the ledge is avoided. The movable member travels along a bar which is yieldinglv mounted so that. the movable member gril or moves laterally relative to 'the station member and avoids the enc ive pressure which, in a direction diamctriczlly across the mouth of the jar, might result in the crushing of the jar.

Referring more in detail to the drawings,` my improved machine includes a supporting base l, carryinga standard 2, on which the main frame structure 3 of the machine is mounted. Secured to this main frame structure are side frames l and 5. Carried by said side frames, at one end ot' the machine, is a pulley G. At the other end ot the side frames is a pulley 7. The endlos"- conveyor belt S runs over these pulleys G and 7. lillounted in the main frame 3 is a main shaft 9, arrying a gear wheel, l0, which meshes uith a gear wheel carried by the armature shaft of the motor il. t will be understood, of course, that the main sha't't may be driven in any suitable way, but l prefer the above means, l am able thereby to provide a self-contained machine.

On the shaft 9 is a beveled rear i3. ji shaft lll extends lengthwise of the machine and carries a gear l2 which meshes with a gear i3. This shaft i-lcarries a beveled gear l at its other end, which in turn meshes With a beveled gear 7,6, carried b v a vertical shaft` i7. The vertical shaft l? earries a. spiral gear 13 Which meshes i .i a gear 19 on a cross shaft 20. This eros matt 20 carries a sprocket Wheel over which a sprocket chain 2l runs, and this sprocket chain 2l in turn runs over a sprocl-:et Wheel carried by the shatt on which the pulley 7 is mounted. rlhus it that the pulley 7 is positively driven from the motor and this drives the endless conveyor.

The jars enter from the left-hand end of the machine, as vievved in Fig. l. hey are fechon to the conveyor belt and are conveyed by said conveyor belt into the machine. Suitable guide rails 24- guide the as it enters the machine. The jars to be closed are provided with al ledge at their upper ends, of the Well-known character, and the metal cap has a flange which is adapted to be turned underneath saidL ledge.

In Fig. 8 of the drawings, l have shown a jar indicated at J, with a metal cap C ing lightly thereon. Said jar l is a ledge i underneath which the loiver portion c of the flange of the metal cap is adapted to be turned for securing the cap to the jar. lt essential that the cap shall be seated on the jar before it enters the closing' mechanism of my machine. ln order that this may be insured, l have provide-d a travelj pressure means underneath which the jars pass. Said pressure means consists of a travelingl belt 25, running over pulleys 26 and 2T. These pulleys are mounted on a frame 28 which is pivoted at to the frame of the machine. A rod il() extends through a b 1acket arm 3l, also mounted on the frame of the machine and this rod has a ball head connection with the frame supporting the pressure means. A. spring' 32 surrormds this rod 30 and bears at one end against the bracket 3l and at its other end against a nut on the rod. This spring normally presses the rod downwardly and thus holds the traveling' belt 25 in contact with the jai-sv; passing beneath the same. The entire frame 28 can yield bodily compre-1sing the spring 32. rlhe downward movement of this pressure device is limited by means of nuts 34.

Mounted in the side frames l and 5 is a shaftl This shaft carries a sprocket Wheel which is driven by a sprocket chain 36. rlhis sprocket chain 36 runs over a sprocket Wheel on the shaft 20. A belt tightener 37 is provided for the sprocket chain 3G to take up the slack therein as the belt is of considerable length and this belt tightener serves as a means for holding? the chain. from contact With the frame and insures the free running` of the chain. A. beveled gear on the shaft 35 meshes With a beveled gear 33 carried by a vertical shaft 39, and this shaft 39 in turn carries a beveled gear l0 which meshes with a beveled. gear on the shaft ell Which carries the pulley 27. Thus it is that the pulley 27 is positively driven and this drives the traveling belt 25. A plate 4t2 `carried by the frame 28 backs up theportion of the belt between the pulleys. The belt travels over this plate and the plate prevents the belt from yieldin except as the entire frame yields.

lt will be readily seen from the above that as the jar passes underneath 'this pressure means the metal .cap will be pressed dovvn onto the jar and fully seated thereon. The jars, of course, are supported and carried along by the conveyor belt 8 at this time.

Rising from the main frame members are four posts 43. Tivo of these posts are located adjacent the entrance end of the machine and the other tivo at the delivery end of the machine. There is a yoke i4 for each pair of posts which extends across thc machine. Mounted to slide freely on each pair of posts is a cross head llo. A rod (3 secured to the cross head and this rod passes up through the yoke member del. The rod 46 is threaded throughout a pori; 'ihis rail 8l' is carried by projectine rods C1 2 which inserted in openings in the .side trame l and are adjustably secured therein by set screws 8?). rllhe guide rail Si hasl an upper inwardly projecting; member lfland a lov/'er inwardly projecting member which are spaced from each other. Said lower member carries a hardcned plate 86 and the plates 7l and 72 travel between this hardened plate 86 and the ovcrhanging member Sil. rl`he pivot pins connecting' the plates to torni the endless chain ride along this hardened plate 8G and this insures that the plates Tl and T2 will move in a horizontal line.

Located in rear of the conveyor chain formed by these plates and links is a bar 87. Said bar is carried by bolts 8S9 which extend through openings in the rail 8l and springs 89 between this bar 8? and the rail normally press the bar 87 outwardly. .Said bar is formed with projecting ledge 90 which extends between the plates '7l and 72 and further aids in holding the chain conveyor so that it will travel in a horizontal line. limit the outward movement of the bar S7. The inner upper tace of the plate 72 is beveled, as clearly shown in Figi. 5 of the drawings, and the lower inner face otl the plate 'Tl is likewise beveled. The metal cap which is shown in dotted lines in Fig. 5 lies between these beveled t'aces and is engaged thereby.

-it the delivery end of the machine there is ay vertical shaft 92 which carries a beveled gear 93 at its lower end meshing in turn with a beveled gear 94 on the shaft 20. rllhis shaft 92 extends through the sprocket wheel and said sprocket wheel T7 is splined thereto so that the rotations of the shaft will impart rotations thereto. The reason that the sprocket wheel is splined to this shaft is that the sprocket wheel and the mechanism associated therewith are mounted in bearings carried by the side rail 5l and are vertically adjustable therewith so as to set the machine tor different heights of jars. Said side rail has projecting brackets 95 which serve as a bearing` snpport for the sprocket Wheel 77. At the other end. of the machine there are brackets 9G.j carried by the side rail which support the sprocket wheel 76.

There is a housing or guard rail 97 which extends about this traveling chain except Nuts 91 threaded on the bolts 80,

Iwhere the chain is running in the recess at the opposite sides ot the ina-chine is such `that the cap will be forced into the recesses between the plates 5.7 and G0, bringing,l the lower edge ot the cap into contact with the beveled face 39 ot the plates (S0. This beveled tace 59 which is ribbed will operate to break or corrugate the lower` edge of the liange of the metal cap and start the turningjy of the same underneath the ledge on the bott-le. ils soon as this lower edge ot the fiange is bent by means ot this beveled edge the spring pressure operating upon the plates 7l and 72 will crowd the jar back and up into the recess, and the ar will be lifted from the endless conveyor and supported in the remainder of its travel through the machine by said ledge at the mouth oi the jar. its the jar rolls along` the rail 57 the flange will be turned to a greater extent underneath the ledge and the jar and cap brought up into the recess. as clearly shown in Figi". f) of the dra-wings. Atteithe flange is well turned underneath the ledge then the cap and jar will pass onto thev section et the rail 62 having the horizontal tace These yielding` plates 62 ill turnV the frange to substantially horizontal position underneath the ledge. Said plates will yield to any exces 've pressure caused by unerenness in the thickness of the metal or the glass formingr the ledge at th-e mouth of the jar and vill prevent said jar from beingY crushed. Furthermore. inasmuch as the jar is lifted from the conveyor belt and the pressure which turns the metal cap imderneath'the ledge is all applied directly at the month of the jar by the yielding` pressure ot the plates 62, it will be seen that there is no danger ot crushing the jar by reason of the fact that the jars vary in height and a jar of more than the average height passes through the machine. The jars when they leave the plates 62 will pass down the curved ledge TO and be gradually lowered on to the conveyor belt which will convey them out of the machine. The travelling chain which. conveys the jar through the machine ancL causes it to turn or roll alongi` the closing' rail can likewise yield to extreme diameters of jars and this prevents any liability of creating a pressure diametrically of the mouth of the jar which is lik-ely to crush the same.

Said guide rail is provided with lugs lOO.

Adjusting bolts 101 are secured to these lugs so that said bolts may be turned, but they cannot move endwise in the lugs. Said bolts are carried by threaded projecting sleeves 102 toi-mcd as u jert of the side rail of the machine. By turning these adjusting bolts 101 after the bolts have been looseiied, the upper' guide rail may be adjusted towarc or away from line center ot the ina- -chine and thus set to accommodate jars of different diameters. The entire frame can be raised and lowered by the hand wheels A8 and thus take care oit jars of different heights, as has already been stated.

At the delivery endof the machine'there is a disk 103 which disk overlies the conveyor belt and is adapted to receive the jars from the conveyor belt. Said disk is carried by a shaft 105, mounted in a suitable bearing 106 on the main frame.` This shaft carries a beveled gear 10T which meshes with a beveled gear 10SEL on the shaft 23 which carri-es the pulley 7 Byy this mechanism the disk is rotated. The edge oit the disk is beveled so that the jars may be readily forced up onto the disk by the conveyor. A guide rail 108 mounted at 109 on the main frame extends over the conveyor belt and the rotating disk and directs the jars onto the disk. A radial guide rail 110 extends to the outer edge of the disk 103 and operates to strip the jars :from the disk. In order to determine the setting ot the machine Jfor` provided gage different size caps,y I have plates 11.1, carried by the upper frame strueture and the adjustable rail is provided with a point-er 112. This gage plate has agage formed thereon and the finger cooperating therewith will indicate the size of the cap for which the machine is set. This gage is in millimeters as caps are usually referred to by their diameter in millimeters.

It is thought that the operation of the machine will be obvious from the detail'description given above. The jars with the caps lightly resting thereon are placed on the conveyor belt and are conveyed thereby underneath the pressure mechanism which seats the cap on the The caps then pass in between the spaced rails along the sides ot the machine, one of which carries the traveling links and carries the plates for turning the metal underneath the ledge on the ar. As has been described the lower edge ot the metalcap is first more or less broken or corrugated by the. ribs on the rail forming a part of th-e closing means, and the edge of the flange turned underneath the ledge at the mouth ot the jar. The ar is supporte the closing means on the one side and the traveling chain on the other side and as the jar passes through the machine it will be turned or rolled along the closing rail, the flange of the cap turned 'further and further the other of which.

d by

under the ledge and finally the yielding pressure means will 'torce the undeiturned part up against the lower portion ot the ledge and thustightly seal the iii-etal capv to the jar.

It will b-cnoted that the rails tor turning the 'flange underneath'the ledge on the cap which yield are made to yield in independent sections so that the jars may be ted through the machine closely 'following each other and if one rail yields, because of eXtra 1hickness of the metal on the ledge at'the mouth of' the jar, the next following jar will be properly closed as'it is only the plate which engages the cap and ledge that will be moved.

lt some times occurs that the spilled contents of a jar or broken jar will stick to the conveyor belt S,v which would cause trouble when another jar enters resting on the same. In order to avoid this, I have provided a scraper' S, carried bya yielding arm A, which presses against the lower face of the traveling conveyor belt and scrapes off any accumulation thereon.

lt is obvious that minor changes in the details of construction may be made without departing 'from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what l claim as new and desire t0 secure by Letters Patent, is-
