CAN-'HEADING MACHINE.

To alt iohont it may concern:

Be it known that 1, ANDREW W. LIVING- 's'roN, a citizen of the United States, residing in Alameda, county of Alameda, State of California, have invented an Improvement in Can- Heading Machines; and I hereby declare the following to be a full, clear, and exact description of the same. 7

My invention relates to improvements in can-heading machines of the type where the can-body with head in position is received between revolving chucks upon a revolving drum and the flanges of the head and body seamed by engaging with the crimping members.

My invention consists, first, in means by which the lower chuck is raised to clamp and hold the can against the upper chuck, and, second, in means for bringing and holding the crimpers in contact with the can-flange, and, thirdly, in causing the drum and chucks to revolve in the same direction.

The object in each instance is to avoid injury to the can by effecting a more gradual and more uniform action of the various parts than is accomplishedby the ordinary appliances in use.

The details will be set forth more fully hereinafter, having reference to the'accompanying drawings, in which- Figure 1 is a plan of my invention. Fig. 2 is a vertical section on the line a: or of Fig. 1. Fig. 3 is a diagram of'the lower driving-gearing. Fig. 4 is a detail plan of the crimping or seaming mechanism. Fig. 5 is a section on the line y 'y, Fig. 4. Fig. 6 is an enlarged front elevation of the lower chuck. Fig.7 is a side view. Fig. 8 is a section through a can body and head.

A represents a drum revoluble upon the shaft 2 and upon which are the brackets-3 and 3, carrying the respective upper and lower chucks 4 and 5. Motion is imparted to the drum and the upper set of chucks by the following chain of gears: 6 is a main driveshaft suitably connected, as by the bevelgearing 7, with the shaft 2. The latter has a small gear 8 meshing with a large gear 9 upon a shaft 10. This shaft 10 carries'a pinion 5o 11, meshing with an idle gear 12, which in turn engages the gear 13 on the hub 1 1 of the drum to drive the latter. The upper end of the shaft 2 is provided with a large gear 15, which meshes with a pinion 16 on the shaft of each of the upper set of chucks 4 to revolve the latter. By reasonof this gearing the drum and chucks will each revolve in the same direction. The necessity of such similarity of movement will be shown later.

In Figs. 2 and 8 is shown a can-body B, provided at either end with the annular flanges b, and also a can head or end 0, having an annular flange 0, corresponding to the flange b of the can-body. By suitable means (not necessary here to be shown) the end is inserted on the can-body with the adjacent flanges b and c in close contact. the can is delivered upon a lower chuck 5, the latter is raised to bring the headed end of. the can against the upper chuck, whereupon the can is rapidly revolved and brought successively against the seamers or crimpers in a manner to be described later.

The raising of the lower chucks is efiected as follows: The spindles 17 of these chucks are slidable vertically in their bearings and the chuck is .turnable independently of the spindle. These spindles each carry a crosshead 18 below, to which a box 19 is resiliently supported by means of'the standards20 and springs 21. A bell-crank lever 22 is pivoted to the bracket 3, audits shorter arm is provided with a roller 23, movable in the box 19. The bell-cranklever has its longer arm in the form of an arc of a circle and carries a roller 24 at itsouter end. This lever is the important feature of this part of my invention. As the drum' revolves with a'can in place upon the chuck 5 the roller 24 engages an incline or cam 25, secured to the'frame of the machine. The length of this cam and the rela- Thus in position tive lengths of the arms of the bell-crank lever are such that the chuck will be gradually lifted till the other end of the can is brought against the upper chuck and the short arm stands vertically, so as to automatically lock the can so forcibly against the upper chuck as to cause the can-body flange resting on the chuck to crinkle or be bent upward from the horizontal, so that the can would sometimes slip in the chucks when brought against the crimpers, because with a short straight lever, as shown in my Patent 690,593, the stationary cam engaged by it is necessarily sharp and necessarily operates in the nature of a fixed stop or projection which the short vertical arm of the lever engages as it passes on the continuously-revolving drum, support, or carrier for the cans and their chucks, whereas with a bent lever having a long arm in this particular combination the stationary cam may be made as gradual as desired and an easygradual clamping movement given to the chuck.

By the use of a lever of the bell-crank lever form and fashioned as here shown I have been able to overcome completely the difliculties previously experienced.

26 represents the seaming-rollers, carried on the swinging arms 27, which are suitably pivoted to the frame, as at 28.

By means of the spring tension member 29 the roller is made to project into the path of the flange edges of the head and body to be seamed. Heret-ofore it has been customary to rely solely on these tension members to hold the seamer against the can. Naturally as these springs had to be still in order to hold the crimpers to the work the result would be that the can-flange would come forcibly against the crimper and the flange would be dented instead of being taken hold of grad ually and turned over evenly. When the crimper let go, the machine would give a noticeable jerk and the next crimper engaged would cause another dent in the can. Also where the drum and the chucks revolved in opposite directions the result was a feeding or drawing in and crinkling of the flange as the chucks brought the can against the roller and occasioning a further unsteadiness in the running of the machine. Hence the obvious purpose of interposing the idle gear 12, whereby all bump of the can against the roller is obviated and the flange feeds up naturally and smoothly to the roller, and instead of drawing in the tendency of the revolving can is to repel the roller.

My other improvement rests in the manner in which I hold the seamer to the can and bring the two into gradual engagement.

Upon the upper side of each of the arms 27 is a plate 30, which is provided with the sinuous guides or cam-surfaces 3i and 31.

Secured to the brackets 3 on the drum are arms 32, carrying rollers As the drum revolves the roller 33 strikes the guide 34 before the seamer contacts with the can, acting to turn the arm 27 on its pivot to bring the seamer gradually against the can, so as to relieve the parts of any shock and consequent liability to indent the can. The roller then engages the surface 31 at the moment the flange contacts with the seaming-roller.

The pivoting of the arms 27 and the sinuosity of the

guides

31 and 34 allow the seaming-rollers or seamers, or crimpers, as they are termed, to be carried out and around the cans and then be drawn in behind the latter before the rollers 33 leave the guides. This insures a positive and continuous engagement of the seamer with the can and at the same time avoids the shock of contact and release before experienced.

It is understood that the tension of the spring members 29 is only such as to cause the arms 27 to lie normally in the path of an approaching can, and were it not for some such means as the roller 33 and the cam-plate 30, by which the several seaming-tools 26 on the swinging arms or levers 27 are positively held or pressed against the seaming-flanges on the can body and cover, the seamer would be pushed out of the way by the can without rolling the seam or being held or pressed against the flanges of the can-cover and canbody with the force or pressure necessary to roll or fold the same into adouble or other seam.

The plates 30 are pivotally secured to the arm 27, as at 35, and each plate is slotted, as at 36. A guide-pin 37 on the arms extends into these slots and the adjustment of these plates is elfected by means of a set-screw 38. By turning this screw the plate is moved so that the roller 33 is made to draw the seamer in more or less against the can according to the pressure desired.

There may be as many seamers successively arranged as is necessary to effectually complete the operation of rolling the seam.

When the can has passed the last seamer, the lever 22 engages an incline 39 on the frame,which trips the lever, causing thelower chuck to drop and release the can. It is thence removed by a guide 40 into a chute or other suitable receptacle.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is-
