CAN-HEADING MACHINE.

To all'whom it may concern.-

Be it known that I, LOUIS C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in Can-Heading Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in can heading machines, and more especially to machines of this type wherein the heading jaws are mounted on a continuously rotating carrier.

An object of the invention is to provide means for closing the heading jaws which shall be simple in construction and positive in action, so that the heading jaws are positively held closed during the heading operation, and positively held open to receive the can body and can ends.

A further object of the invention is to simplify the means for moving the heading jaws toward each other, so as to apply the heads to the can body, said simplified construction consisting generally in devices for moving one head only relative to the other.

A further object of the invention consists in roviding means whereby the heading clevices may be quickly adjusted and positioned for difierent sized can bodies A further object of the invention is to provide means for locking the movable jaw, so that the jaws will be held in locked position independently of the other parts of the machine, and thereby a self-contained jaw head is formed.

These and other objects will in part be obvious, and will in part be hereinafter more fully described.

In the drawings which show by way of illustration one embodiment of the invention, Figure 1 is a vertical transverse sectional view through a heading machine having my improvements applied thereto; Fig. 2 is a partial rear view and partial longitudinal sectional view through the same; Fig. 3 is a detail sectional view through the support for one of the heading jaws, showing the heading jaw in side elevation closed and locked; Fig. 4 is a front view of one of the heading jaws and the parts for opening and closing the same; Fig. 5 is a detail vertical sectional view through the heading Specification of Letters Patent.

jaws; Fig. 6 is a sectional view on the line 66 of Fig. 3; Fig. 7 is an end elevation of one of the cams for operating the heading jaws; Fig. 8 is a top edge view of the same; and Fig. 9 is a bottom edge view of the same.

In carrying out the invention, the operative parts of the improved header are mounted on a framework consisting of a supporting base 1 and upright standards 2, 2, located at each end of the supporting base. Said standards are connected at their upper ends by a cross rod 3. Mounted to turn in said standards 2, 2, is a central shaft 4. Said shaft is rotated from a gear 5, which meshes with a gear 6 on the main shaft 7. A suitable shield 8 may be provided for housing the gear 5.

Rigidly attached to the shaft 4 is a support 9, which support consists of a sleeve 10 keyed to the shaft in any desired way and a radially projecting rib or disk 11 at the outer edge of which is mounted a flange 12. Mounted on the flange 12 of the support 9 are a plurality of heading devices 13. Each heading device consists of two jaws 14 and 15. Each jaw 15 is rigidly connected to a supporting stem 16. The stems 16 for the jaws are clamped to the flange 12. This jaw 15 is also provided with an outwardly obliquely extending support 17 on which the outer jaw 14 is mounted to slide. Also mounted on the shaft 4 and adjacent the other end thereof is a second support 18, which consists of a sleeve 19 keyed to the shaft 4, so as to slide endwise thereon. The shaft 4E is threaded at 20' and a nut or threaded collar 21 engages the threads 20 of the shaft. Said collar 21 rests against the end of the sleeve 19, and is held against said sleeve by a second collar 22, which is securedto the sleeve in any desired way, preferably by being threaded thereto. This sleeve 22 has an inwardly projecting flange which engages the outer face of an outwardly projecting flange on the nut or collar 21. By this construction, the sleeve 19 is secured to the nut 21, and when the nut 21 is turned on the shaft 1, the sleeve 19 will be moved longitudinally of said shaft. The support 18 is also formed with an outwardly projecting rib or disk 23, which carries on its outer edge a plurality of bearings 2%.

The heading devices 13 on the left of the machine are each mounted on a stem or slide 25, which is free to move longitudinally in the bearings 24, formed as a part of the support 18. A cam 26 is mounted on the sleeve 19, so that the sleeve may turn freely within the cam. This cam is held from movement by a stud 27, which projects through a suitable bearing in the standard 2 at the left of the machine. In the outer face of the cam 26 is a cam groove 28, which engages a roller 29 on each of the slides 25, carrying the heading devices at the left of the machine as viewed in Fig. 2.

The heading jaws, so far as the opening and closing means are concerned and the construction of the jaws relative to the heading operation, are precisely the same on each side of the machine. The heading jaw 14, as above noted, is mounted to slide freely on the oblique support 17, carried by the inner heading jaw, which inner heading jaw is mounted on the supporting stem or slide therefor. The outer heading jaw 14 is attached to a stem 30, which rests on the support 17 and is held thereon by a plate 31 through the aid of the screws 32. The part 30 is preferably formed with a slot to receive the screws 32, which are preferably formed with a sleeve or enlarged center portion fitting the slot in the stem 30.

Pivoted to (1166 58111 30 at the point 33 is a yoke lever 34. A yoke link 36 is pivoted at 35 to the lever 34, and at 37 to the shank of the lower aw. On the lower end of the lever 34 is a roller 38. Said roller 38 is operated upon during the rotation of the carrier by separate or sectional cams, so that the roller 38 is moved from the position shown in Fig. 2, to the position shown in Fig. 3, during the rotation of the carrier. These sectional cams are shown in detail in Figs. 7 to 9 inclusive. In these figures, the cam at the left of the machine is illustrated. Said cam consists of a supporting disk or plate 39, and a centrally projecting sleeve 40, so that said cam may surround the shaft 4. The disk 39 is seated against the radial rib 23, and may be held from lateral movement away from the rib by a ring cap 41, (see Fig. 2), which ring cap is bolted to the rib 23.

As herein shown, the sleeve of the cam disk 39 is recessed to receive the end of the sleeve 19 forming a part of the support 18. The disk 39 and sleeve 40 are provided with two sectional cams 42 and 43. Said cam disk is held stationary, so that the carrier moves about the same in the direction of the arrow in Fig. 7. As the carrier rot-ates, the roll 38 will engage the surface 44 of the cam 43, which is inclined from the point 44 to the point 45, so as to gradually force the roll 38 from the position shown in the upper half of Fig. 2, to the position shown in Fig. 3. The cam 42 is formed with a surface 46 which engages the roll 38, and said surface 46 is inclined from a point 47 to a point 48, so that the roll. will he gradw ally forced from the position shown in Fig. 3, to the position shown in the upper half of Fig. 2. Said cam is also provided with a surface 49, which operates to hold the roll 38 forced to the position shown in the upper half of F ig. 2, wherein the movable heading jaws are held positively in open position.

The pivotal points of the lever 34 and the link 36 are so disposed that when the movable heading jaw 14 is in closed position, said pivotal points are in line, as shown in Fig. 3, and thereby the heading jaw 14 will be self-locked in closed position. I am, therefore, able to use sectional cam for operating the heading jaw, for the reason that as soon as the jaw is closed, the toggle link closing devices will hold the same closed and self-locked. During the operation of the carrier, the roll 38 will, therefore, engage the cam 43 at the point 44, and the jaw will be forced downward to closed position, if for any reason the weight of the jaw does not carry the same down when released by the supporting cam 49. As soon as the jaw is positively closed and locked, the roller 38 will leave the surface 44 at the point 45, and the roller will be entirely free from any cam action until the heading operation has been performed, and it is desired to open the heading jaws. The cam roller 38 will then strike the inclined surface 46,

and 'radually open the jaws, and the roller resting on the surface 49 will hold the aws open until the point 44 is reached, when the jaws will be released, so that they may close or be closed by contact with the independent cam 43.

The cam disk and sleeve at the left of the machine, as viewed in Fig. 2, is similar in all respects to that at the right, except that the cam 42 is spaced a greater distance from the cam 43. The heading jaws on the left of the machine are moved longitudinally of the machine relative to the heading jaws on the right of the machine to place the head on the can body, and, therefore, the cams for operating the heading aws at the left of the machine, as viewed in this figure, are spaced a suflicient distance to allow this 1ongitudinal movement of the heading jaws to perform the closing action. By the improved construction herein shown, wherein the jaws are positively self'locked, the cams for operating the jaws may be spaced so as to allow this longitudinal movement of the heading jaws.

Each of the cam disks 39 is formed with a socket 50. A rod. 51 extends from one socket to the other, and also extends through an arm 52, which freely engages the shaft 4 at one end, and at its other end is connected to a rod 53, which is mounted in brackets 53. The brackets 53 are carried by the standards2. On the yokes 54 is a chute 55,

for the can bodies. Said chute consists of spaced rails 56, along which the can bodies roll, and guiding rails 57. These rails 56 and 57 are so shaped as to convey the can bodies downwardly in a vertical direction, and then radially of the movement of the carrier for the heading devices, so that the can bodies will be dropped one after another into the lower jaws of the heading devices. Chutes 58 for the can ends are disposed along the side of the chute for the can bodies, so that a can end will be delivered to the jaws 15 at each end of the can body.

The jaw 15 of each heading device is formed with an inner semicylindrical surface 59. A supporting plate 60 is threaded on the end of the supporting stem or slide for the heading jaws, and is located within the jaws l4 and 15. Said supporting plate 60 as herein shown, is cylindrical and fills the entire space between the jaws 14 and 15 when the same are closed. The can end is fed into the jaw 15 and rests against the supporting plate 60. The lower jaw is preferably grooved as at 61. The upper jaw 14 is similar in shape to the lower jaw, but is tapered at 62 to aid in properly centering the can body and forcing the same into the can end or head within the'jaws. Said up per jaw is also grooved at 63 to correspond with the groove 61. These grooves 51 and 63 are for the purpose of forming a space to receive any outward curl that may be formed on the can head, and preventing improper contracting of the flange on the can head on the closing of the jaws.

In the operation of my machine, the cams for operating the movable jaws of the heading devices are so positioned that when the heading jaws pass underneath the chutes for the can body and can ends or heads, said movable jaws are raised,.as indicated in the upper half of Fig. 2, so that the can body and can heads may drop into the lower jaws and be supported thereby. A further movement of the carrier will bring the roller 38 out of contact with the cam 42, which will release the movable jaw, and the same will slide down the oblique support for the same on to the can body and head supported by the jaws 15. The cam 43 will engage the roller 38 and force the jaw downward, if for any reason the same does not move freely, and, furthermore, the cam 43 will engage the roller 38 and force the lever 34 to a past center position, so that the pivotal points 33, 35 and 37 are practically in line, and the upper jaw will, therefore, be locked in closed position. A further movement of the carrier will cause the cam 26 operating upon the rollers 29, to move the heading jaws at the left of the machine toward the heading jaws at the right of the machine, and this will force the heads in each pair of jaws on to the can body. The continued movement of the carrier will cause the rollers 38 to contact with the cams 42, which will move the jaws 14 away from the fixed jaws 15 and release the can body from the heading jaws. A discharge chute 64 is secured to the supporting frame, and the can bodies with the heads applied thereto will roll down said chute. In order to assure the can bodies with the heads attached being discharged from the heading jaws, I have provided a stripper arm 65, which is secured to the bar 52, and is formed with a curved outer end 66, which lies in the path of movement of the can bodies, so that if they do not drop from the jaws when opened, they will be forced therefrom through the continued movement of the carrier.

It is obvious that minor changes in the details of construction and arrangement of parts may be made, without departing from the spirit of my invention, as set forth in the appended claims.
