T 0 all whom it may concern; I

Be it known that LOTTO H. JENSEN, a citizen of the United States, residing at Buf-I falo, in the county of Erie and State ofNew York, have invented new and useful'lmprovements in Beading-Machines, of whichcessively and expeditiously, with a view of materially reducing the cost of manufacture of such covers.

A furtherobject is to so organize the machine that it can be readily adjusted to operate upon covers of various sizes.

Insits general organization, the machine comprises a horizontal feed table for the cover-blanks, a rotary chuck and. a cooperating beading roller arranged to receive the cover blanks successively from said table and bead their edges, perforating and printing dies arranged to receive the beaded covers from said chuck, and traveling'coversupports or v carriers for conveying the cover-blanks from said table to the heading devices and said dies and finally discharging the completed covers from the machine.

1 indicates the stationary main frame of the machine which is preferably in the form of a hollow rectangular casing or pedestal and 2 is the main driving shaft of the machine arranged transversely in the frame and having a driving pulley.

Supported at the head of the machine by a bracket 4 or other suitable means, is a horizontal feed table 7 upon which the coverblanks 8 are. successively placed by the operator. This table is somewhat narrower than said blanks so that they overhang it, as shown byfldotted lines in F ig. 14. This table may be provided near its front end at opposite sides with a pair of gages 9 for properly positioning the blank thereon,

these gages being adjustable toward and from the center of the table to suit different sized blanks. the gages are mounted on a pair of horizontal rods arranged radially of the table and to, which they are adjustably clamped by set screws 11* or'other Suitable means.

Located on opposite sidesof the feed table different sized covers, as hereinafter more,

fully described. In the construction shown. the carriages are simultaneously adjusted by a rotary transversescrew 20 having right and left threads which respectively engage correspondingly threaded lugs 21 depending from the carriages, as best shown in Figs.

In the construction shown,

15 and 16. This adjusting screw had a hand wheel 22 for turning it. The carrying rods 12 are reeiprocated in unison and prothe cover-blanks from the feed table to the In the construction beading mechanism. shown, each of said rods is provided with a pair of such fingers which stand opposite he central portion of the feed table when the rods 12 are at the extremity of their return stroke, as shown in Fig. lei.

Any suitable means may be employed for actuating the carrying rods 12. The mechanism shown in the drawings for this purpose comprises a reciprocating gear rack 24 arranged below the bed of the main frame lengthwise thereof and traveling in fixed guideways 25 carried by upright guides or bearings 26, 27, secured to said frame. This gear rack is actuated by a grooved rotary cam 28 which engages an anti-friction roller 29 carried by the rack, as shown in Fig. 12. This cam is secured to a countershaft 30 driven from the main shaft by gears 31, 32, as shown in Fig. 3. 33 indicates a pair of heads or slides secured to the carrying rods 12, respectively, and guided upon the laterally-movable carriages 18, as shown in Figs. 14 and 15. These slides are provided with longitudinal rails 33 which run upon supporting rollers 33 mounted on the arms 17 of the carriages 18. Secured to the an dersides of these slides are longitudinal rack bars 34 which engage gear wheels 35 secured to a transverse shaft 36 journaled in the carriages 1S and connected with the lower gear rack 24 by a suitable gear train 38%12. In the arrangement shown, the shaft 13 of this gear train is hollow and is concentric with the carriage-adjusting screw 21), which latter passes freely through it.

In addition to their reciprocating motion, the carrying rods 12 are capable of a rocking or oscillating motion in their bearings for the purpose of opening or closing the carrying fingers to engage or clear the cover-blanks placed on the feed table, e. to spread the opposing pairs of fingers on the return stroke of said rods and causethem to approach and engage under the blank on the table and deliver it to the heading mechanism on the effective stroke of said rods. This rocking action is preferably effected by alpair of hollow arms 14; extending inwardly from said rods and a pair of links 4-5 which slide freely therein and are pivoted at their inner ends to the upperend of asliderod 16 by a horizontal pin 47, seen in Figs; 8, 11 and12. This rod moves vertically in a fixed guide 48 and is actuated by a rotary cam 19 keyed to the countershaft 30. This cam is constructed torock the carrying rods 12 outwardly on their return stroke and inwardly 011 their effective stroke, thus opening and closing the carrying fingers accordingly.

As shown in the drawings, these fingers are provided at a short distance from their inner ends with beveled stops or shoulders 50bwhich center the cover-blanks on the feed ta le.

Preferably, the fingers are adjustable toward and from the feed table as well as lengthwise thereof to adapt them to coverblanks of different sizes. For this purpose, there is fixed to each rod 12 a standard 51 carrying a head 52. This head is provided with transverse grooves or seats 53 in any one of which the shanks of the fingers may be placed, and in which they are retained by a cover 54: removably fastened to the top of the head. Each pair of fingers may also be adjusted toward and from the feed table by a gear pinion 55 mounted on a shaft journaled in the corresponding head and engaging teeth 56 of the fingers, the shaft of the pinion having an external knob 57 for turning it.

Arranged a short distance beyond and in line with the feed table is the coverbeading mechanism which is preferably constructed as follows:

58 and 59 indicate the upper and lower disks or members of a rotary chuck between which the cover-blank is adapted to be clamped and by which it is rapidly'rotated while in contact with a grooved horizontal beading roller 60 cooperating with the chuck. The upper chuck-member 58 is re movably secured to the lower end of a rotary spindle 61. carried by a standard 62 rising from the bed of the machine, this shaft having a pulley 63 which is suitably driven from the main shaft 2. The lower chuckanember 59 is removably supported upon the upper end of a vertically-movable plunger 64 preferably by a ball bearing 65. This plunger slides in the front guide 26 and is elevated by a cam 66 mounted on the counter-shaft 30, the downward movement of said lower chuck-member being effected by gravity. As shown in Figs. 6 and 12, the opposing faces of the upper and lower chuck-members are shaped to conform to the cover-blanks, and they are of the proper diameter to allow the rim of the cover to,

project beyond them, as shown in Fig. 7. The beading roller 60 is arranged adjacent to the edge of the upper chuck-member and mounted on the front arm of a horizontallyswinging lever 67. The rear arm of this lever carries an anti-friction roller 68 which is engaged by a vertically-movable wedge or cam 69, which on its upward stroke forces the heading roller against the projecting rim of the cover, beading the same. This cam is formed at the upper end of alvertical rod or plunger 70 sliding in a guide-71 carried by the standard 62 and actuated by a grooved rotary cam 72 keyed to the counterbeading roller to covers of different sizes,

its carrying lever is made adjustable'toward and from the beading chuck. For this purpose, the lever pivot or fulcrun'i-pin 74, Figs. 10 and 18, is preferably carried by a slide or follower'75 guidedin a groove 76 in the underside of the lever-bracket 77. The lower portion of the fulcrum-pin which extends below the bracket carries the lever,

while the upper portion'of the pin passes through a longitudinal slot 7 8 of the bracket and is provided with a lock nut 79 for retaining it inposition. The fulcrum pin is adjusted in this slot by a rotary screw 80 held against longitudinal movement in said bracket and engaging a threaded opening in the follower 7 5. I w

As the upper chuck member 58 rotates constantly duringtheoperation of the machine, the lower member on receding from it would continue to spin and be liable to throw the beaded cover off by centrifugal force, in the absence of some means to stop such rotation. The device. shown in the drawings for this purpose consists of a brake or brake disk 81 arranged underneath the lower chuck-member 59 and loosely en' circling its hub, as shown in Fig. 12-." This brake disk is carried. by the forked front end of a vertically-swinging lever 82 fulcrumed on a bracket 83 depending from the feed table 7 or other suitable support. The forked end of this lever is constantlyurged upward by a spring 84 connected to its rear arm, the upward movement of the brakelever being limited by a stop 85 arranged to be encountered by the rear arm of the lever. Upon the ascent ofthe lower chuckmember, the spring 84: causes the brake disk to follow it up untilthecover nearly touches the upper chuck-member, when the brake disk is arrested by the stop 85, thereby allowing thelower member and the. cover to rotate freely with the upper member. Immediately after thelo-wer member begins its descent and before the chuck-members become separated sufficiently to release the beaded cover, the lower member comes'in contact with the brake disk which promptly arrests its rotation, preventing the cover from flying out of the chuck. e x

A weight 85 ispreferably employed to hold the cover-blanks upon the lower chuckmember while the latter rises and descends.

This weight is attached to the lower end of a guide-rod 85 which slides in the spindle 61. The upper chuck member is provided tive stroke of the rods.

, lows said weight and allows the cover blank to bearfully against said face.

Adjacent tothe beading chuck the carrying rods 12 are provided witha second set of supporting fingers 86 similar to the fingers 23 which engage under the beaded edge of the'co-ver on the return stroke of said rods and carry it onward betweenthe per-' forating and stamping dies on the next effecmale and female members of these dies which are formed to produce the desired imprint upon the covers, such as the manufacturers name and trade-mark. In addi-' tion to such lettering, the upperdie 88 is provided with punches 89 for forming the desired slots or apertures in the cover to receive the usual clips of the handle, the lower die being provided with correspondingrecesses 90 to receive the punches, The stationary upper die is secured to a standard 91 mounted on the bed of the machine, while the relatively movable lower die is carried by a plunger 92 sliding in the rear guide 27 and actuated by a cam 93 mounted onv the oountershaft 30, as shown in Fig. 12. Associated with the upper die member is a spring-pressed stripper 9 1 of ordinary construction.

I Located opposite the dies is a third set of supporting fingers 95 mounted on the carrying rods 12 and adapted to convey the printed and perforated covers from the dies to the rear end of the machine. Like the first and second sets of fingers, those of the third set clear the covers during the return stroke of said rods and carry them onward upon the effective stroke of the rods.

Theoperat'ion of the machine is as fol-' Power being transmitted to the main driving shaft 2, the carrying rods 12 are re ciprocated as before described, their stroke being equal to the distance between the centers of the beading" chuck and, the dies. Upon now placing a cover blank on the feed table 7, the first/setof fingers 23 advance it to a position directly over the lower chuck-member 59, which thereupon rises and presses the cover-blank againstthe rotating upper: chuck-member 158. As soon as the blank reaches thisposition, the beading roller 60 is forced against its edge by the cam 69, heading the same in an obvious manner. Immediately after the beading operation, the lower chuck-member recedes fromthe upper one and deposits the beaded cover upon the second set of fingers 86, which in the meantime have been brought to their initial position and swung inwardly to support the cover. The rods .12 now again move rearwardly, carrying the beaded cover between the dies 87, 88, which 87, 88 indicate the a receptacle or suitable place of delivery at I by the rocking action of said rods, releasing and dropping the cover.

The cover-carriage composed of the carrying rods 12 and the several sets of fingers, comes to a standstill at both ends of its stroke while the beading and perforating and printing operations are taking place.

It will be understood from the foregoing that a plurality of covers orblanks are constantly passing through the machine and automatically beaded, perforated and printed, it being only necessary to feed the blanks to it by hand, which can be done by unskilled labor.

It follows that by the use of this machine, the manufacture of such covers is greatly expedited and their cost considerably reduced. a

The machine moreover, can be adapted to different sized covers by substituting larger or smaller chuck- members 58, 59, for those shown, and adjusting the beading roller accordingly, as hereinbefore de scribed.

The carrying rods 12 are also adjusted toward or from each other for this purpose by means of the right and left screw 20, the principal or coarse adjustment being effectedby this screw, while the finer adjustment is effected by shifting the carrying fingers by means of the pinions 55.

The speed of the carrying rods is the same for various sized covers, but the speed of the beading chuck is preferably varied according tothe diameter of the covers, being higher the greater their diameter. Any suitable speed changing gearing may be em: ployed for this purpose. In the drawings, only a part of this gearing is shown at 96, 97 and 98.

IVhile this machine is designed more particularly for beading, perforating and printing pot-covers, it may obviously be used for producing other articles of a similar character.
