Application filed a rn 20, 1921. Serial no. 482,845.
To all whom it may concern: I
Be it known that 1, Henry L. Gonnrnnn, a citizen or the Unlted States, residingat L p i Los rrngeles, 1n the county or Los Angeles and State of California, have invented new and useful ISHPI'O'V'GIHIGIllZS in Searning Heads for Double-Seaniing Ma chines, oft which the following is a specification.
This invention relates to double seaming machines and particularly pertains to a seaming head therefor.
t is the principal object of the present invention to provide novel means whereby a double seam may be formed between a which a can body and its cap may be gripped to produce rotation thereof, seaming rolls being provided to form a seamed joint between the can and its cap, said rollers being yieldably held adjustably support ed and positively actuated to produce pressure against the can.
The invention is illustrated by way of example in the accompanying drawings, in which: i A
Figure 1 is a fragmentary view in vertical section and elevation showing a double seaming machine and the present invention applied thereto.
Fl 2 is a view in section and elevation as seen on the line 2-2 and viewed. in the direction oi. the arrows as indicated in Fig. 1.
l ig, 3 is a fragmentary view'shovfing the manner in which the roller support is adjusted relative'to the turretspiden Broadly considered, the preaent invention is applicable. to a double seaming machine having rotatable spindles between which a can and its cap may be secured and at which time a seam may be .iormed by a roller.
The machine disclosed in the drawings coinprises turrets A and B, mounted upon a main frame 10. The turret is designed to produce a first seaming operation," and the turret B a final rolling operation to produce a complete double seam. These tur rets rotate around central vertical shafts 11, extending upwardly from the base 10. Disposed centrally around these shafts are sleeves 12 carrying a lower spider 13, an up persgider 14s and a top supporting spider 15. These members all rotate with the sleeve, and are preferably pinned thereto as indicated at 165 The lower spider 13 carries tour reciprocating spindles 17. These spindles are spaced equal distance from each other and extend vertically through bearings of the spider.
The drive for these turrets comprises a train of gears QOsecured'tothe lower end of the sleeves l2 and to a spindle 21. This swindle carriesa transfer member 22 'b' which the cans may he [transferred from turret A to turret B.
Cans 22 are intended'to rest, upon circular supports 24%, formed at the uppcrends of the spindles 17. supplied with a cap 25 before it is delivered to the first turret A and as shown in Fig. 1 this cap is recessed. Arlaniping head 26 extends into the recessed portion of the cap,
while a stripper plate 27 is mounted within the clamping head and rests upon the cap, so that thehead may be readily separated from the cap when withdrawn. An expansion spring 28 acts between a shoulder with in the cap and the upper face of the strip per plate. It will be understood that the vertical axes of the clamping heads and the spindles 17 are in longitudinal alignment." Tlieheads 26 are secured'to' the lower ends of drivingspindles 29; These spindles are rotatably" supported through vertical bearings 30 of lt-he'u'pper spider 14:.
The present invention is more particularly concerned with the structure of the spider 14 and the mechanism supported thereupon. Reference being bad to Fig. 2, it will be seen that this spider has a substantially circular web, with which the bearings 30 are formed. Disposed beneath theweb portion of the spider is a substantially-square adjusting plate 34. This plate is formed with slotted openings 35 disposed on a circle concentric with the axis of the spider. openings receive bolts 36, which are fixed relative to the web of the-spider as shown in Fig 1, and extend downwardly through the slotted openings of the adjusting plate.
It will therefore be seen that by loosening the bolts 36 the plate may be rotated around the central axis of the turret and the positions of its corners changed relative tothe spider 14. p 5 I i The corners of the adjusting plate 34 carry pivot bolts 37. These bolts are secured in bosses 38 formed as a partof the plate 34 and extending upwardly therefrom, slotted openings 39 being formed in the web of the spider 14 to accommodate these extensions. Bolts 37 pass through cam levers 40 and roller levers .41 The roller levers are provided with forked portions between which the cam lever extends the bolts 37 passing through the forked portions of the roller levers and the intervening portion of the cam levers. The cam levers extend substantially at right angles to each other, and are provided at their inner ends with rollers 42, which rest against a cam 43. This cam circumscribes the sleeve 12 and is fixed to a support bearing 44 secured to the main frame of the machine. The sleeve 12 freely rotates through the center of the cam. Springs 45 are secured to the earn levers and to the spider 14 in a manner to constantly hold the rollers of the levers against the face of the cam.
It is intended that movement of the cant lever 40 shall be imparted to a complementary roller lever 41. This is brought about by an adjustable connection between two levers. A threaded lug 46 extends outwardly from the side of each cam lever 40 and substantially at. right angles to the longitudinal axis thereof. This lug receives an adjusting bolt 47 which passes through a lug 48 extending from the'side of the seat on the lug 46, after.
These roller lever 41. The lugs 46 and 48 are substantially parallel. Mounted upon the face of the lug 48 adjacent the lug 46 is a resilient washer 49. This washer is here shown as of rubber and is inclosed within a metal sleeve 50. The belt 47; passes through this resilient member and carries a washer 51, adapted to bear "against the face thereof. Lock nuts 52 adjustably hold the washer in place. It will therefore be evident that permanent angular. adjustment of a cam lever .40 and a roller lever 41 may be made by manipulation of the bolt 47 in its threaded which it may be fixed by the lock nut 53. Yieldable adjustment may be made by the lock nuts 52 as they press against the resilient washer 49 and regulate the amount ofresiliency which may be obtained from the member 49.
It is to be understood that the roller levers 41 carry seaming rollers v54. These rollers extend downwardly and may be swung inwardly and outwardly relative to the clam ing heads 26 of the driving spindles as controlledby the actuation of the cam arms 40 by the cam 43.
g In operation of the invention the approximatepositions of the seaming rollers 54 relative to the clamping heads 26 and an intervening can seam may be determined by loosening the bolts 86, after which the adjusting plate 34 may be moved by a set screw 55 extending through a lug 56 on the web.
of spider 14. 7 When the desired adjustment can body or inequalities in the thickness of the metal or the seam as rolled may be accommodated by the resilient member 49. This member will. permit the rolls to have a slight yield when desired, without interfering with the effectiveness of the seaming operation. The amount of yield permitted and the pressure required to produce this movement can be determined by adjustment of the lock nuts 52 against the washer 5E.
and the resilient member.
It will thus be seen that by the provision of articulate actuating means interposed be tween the seaming cam and the seaming rolls will produce a desired minute adjustment of these members and that by interposing yieldable means in the adjusting mechanism thereof a more perfect seam may be formed than is at present obtainable on most ma- .chines dae to the tact that a maximum constant pressure is produced against the seam without reference to irregularities or inequalities of the stock being worked upon.
While I have shown the preferred form of my invention, as now known to me, it will. be understood that various changes might be made in the combination, construction, and arrangement of parts, by those skilled in the art, without departing from the spirit of the invention,'as claimed.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
