CAN-HEADiNG. MACHINE.

Specc'ation of Letters Patent.

Patented Aug. 8, 1905.

v Application filed October 28, 1904. Serial Np. 230,400.

To tI/Z whom it may concern:

Be it known that I, J AMES MoGINNIs, a citizen ofthe United States, residing at'Highlandtown, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Can-Heading Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in can-heading machines. It has for its object to provide a machine which will head cans with greater rapidity than those now generally in use, which will be very cheap of manufacture and which will be so simple that it will not get out of order, and each of its parts will be interchangeable with like parts of other machines of this type.

Theinvention consists, broadly, of can-holders orv clamping-molds each comprising two jaws, one jaw adaptedv to slide upon the other to grip or release a can, said can-holders oppositely arranged and mounted upon revoluble frames or wheels, and means to operate each set of jaws to close one jaw upon the other and to move the jaws when closed toward the opposite set of jaws.

The invention also consists in the details of construction and combinations of parts hereinafter described, and more particularly pointed out in the claims concluding this specification.

In the accompanying drawings, illustrating the preferred embodiment'of my invention, Figure 1 is a side elevation of the machine, partly in central vertical section, showing only'two sets of jaws or clamping-molds on each side. While any number of these sets of jaws or clamping-molds may be used on the machine, the number shown in the drawings is purposely restricted for the sake of clearness. Fig. 2 is an elevation of the left-hand end of the machine with the belt-pulleys and gears removed, also for the sake of clearness. Fig..

A 3 is a detail view of the outer cam-groove with the'ispring-pressed section thereof and the brackets for said groove. Fig. 1 is a crosssectional view ofthe same. Figs. 5 and 6 are front and side elevations, respectively, of the jaws of the clamping-mold, the sliding jaw pushed up and back to more clearly disclose the parts thereof. Fig. 7 is a front elevation of the clamping-mold with its jaws closed. Fig. 8 is a central sectional view of Fig. 7,

.through the delivery-chute.

showing the interior construction of the clamping-mold. Fig. 9 is a detail View of one of the shaft-gripping brackets carrying a camroll. Fig. 10 is a horizontal sectional View Fig. 11 is a detail view of the inner cam-groove. is a cross-sectional view thereof on the line a" .fr of Fig. 11, showing the widened portion of the flange for retaining the cam-rolls attached to the sliding jaws of each mold in the groove as said sliding jaw descends to grip a can; and Fig. 13 is a detail view of a modified form of shaft for carrying the molds.

While the preferred embodiment of my invention is fully shown in the accompanying drawings and its construction and operation is clearly described in this specification, the right is reserved to make such changes from the construction shown and described herein as the scope of the claims hereunto appended will permit.

In carrying out my invention I mount the operating parts of the machine upon suitable supports 1, carrying a bed-plate 2, at each end of which are secured upstanding standards 3, having journal-boxes 4. for the main shaft 5. To one of said standards 3 is secured an L- shaped arm 6, arranged with-its upwardly-extending portion oblique to the vertical axis of the machine. Said arm is also provided with a journal-box 7, and the standard 3, to which it is secured, has a lateral extension 8, in which is secured the other bearing of a short shaft 9, carrying belt-pulleys 10, and a small gear-- wheel meshing with a larger gear-wheel 11 on the main shaft 5. The object in providing .these gears, short shaft, &c., is to reduce the speed of the header and adapt it to be used with an ordinary drive-belt. It is obvious, however, that the drive-pulleys may be secured directly to the main shaft, if desired, thus 'doing away with the gears.

Placed about equidistaut from the opposite standards 3 and intermediate of them are upright open circular rings 12, having camgrooves 13, said rings being secured to the bed-plate by bolts 14. Another ring 15, having another cam-groove 16, is secured to each of the rings 12 by means of brackets 17, preferably integral with said ring 15 and fastened to the rings 12 by means of bolts 18. Both of the cam- grooves 13 and 16 open inward toward the main shaft. Near each end of said main shaft and secured thereto are mounted oppositely-facing disks or plates 19. Each of said plates carries a series of moldsaround Fig. 12

its periphery. Each mold is mounted, preferably, upon a square shaft 20, to the outer end of which is secured the gripping-piece 21, suitably keyed thereto against longitudinal movement by a cross-pin 22 and provided with a lug 23, carrying a cam-roll 24, adapted to engage the cam-groove 16, whereby the mold is thrust inward and retracted at the proper intervals as the disk or plate 19 revolves. Each mold comprises a member or jaw 25, fixed to the square shaft, and another jaw 26, slidably secured to the first jaw and carrying acam-roll 27, engagingone of the cam-grooves 13. j The cam-grooves are so arranged with relation to each other that as a mold passes around the slidable jaw is forced inward to a closed position against the other jaw, and then the jaw secured to the square shaft is advanced inward to force the head upon `the can. The cam-g'roove 13 extends inwardly a distance sufficiently greater than d oes the groove 16 to allow the slidable jaw to close before its roll has reached the innermost portion of said groove 13, but when the roll on the square shaft carrying the other jaw has reached the portion of the groove 16 farthest inward. At this part of said groove 16 a separable section 28 of the flange of said grooveis arranged upon bolts or headed pins 29, carrying coiled springs 30, adapted to normally hold said section 28 in alinement with the other portion of said groove 16, but which permits the square shaft and jaw fixed thereto to be carried inward with the slidable jaw by the roll attached to the latter jaw traveling to the innermost extent of its cam-groove 13. The purpose of having the final inward thrust of the mold given by the slidable jaw instead of the other jaw is that it assures the tight closing of the jaws at each operation. Should the other method be adopted and the cam-groove 16 o1` the roll engaging said groove become worn, the result would be that the jaws of the mold would not be closed tightly at the time the head is forced upon the can. The fiange of the cam-groove 13 is wider at the point where said groove extends farthest inward, as at 13, to guide and retain the cam-rolls therein as the slidable jaw is closed. (See Figs. 11 and 12.) Referring more particularly to Figs. 5, 6, 7, and 3, the jaw 25 has an extension or hub 31, having' a round bore to receive the rounded end of the square shaft and having a keyway 32 therein corresponding to a similar keyway 33 in the rounded portion of said shaft. A pin 34 engages said ways and locks the jaw against turning' on the shaft. Said jaw 25 has a semicircular ledge 35, forming half of the mold, and to theinner shoulder of the jaw is secured, by means of screws 36, a disk 37 of about the size of the can-head, so that it extends above the semicircular ledge of said jaw and retains the head on the can when the slidable jaw 26 is withdrawn. Said disk 37 is pro-- vided with a groove 38, registering with the keyways in the jaw 25, for the passage of the pin 34. The upper portion of said last-mentioned jaw rearward of the disk 37 slopes upward and forms a dovetail joint with the slidable member by means of a plate 39, integral with said slidable member or jaw and havin g its edges undercut, as at 40. Said plate and the body of the jaw'25 are slotted vertically, as at 41, behind the disk 37 from above down to the round bore adapted to receive the rounded end of the square shaft 20, whereby a washer 42 may be dropped into place and a bolt 43 passed therethrough and screwed into the end of the shaft, thereby retaining the locking-pin in place and securing the jaw upon the shaft. front of the disk 37 to receive the can-heads.

The slid able jaw 26 has its semicircular su pplemental fiange 45 rounded out at its edge, as at 46, to shape up any irregularities in the edge of the can-body as said jaw closes upon its companion. The operating cam-roll for said slidable jaw is mounted upon an adjustable plate 47, having' an elongated slot 48, through which passes a bolt 49, whereby said plate is secured to the jaw. By means of said slotted plate the slidable jaw may always be adjusted so as to take up any wear upon the parts and insure the tight closing of the jaws of the mold. It will be noted that the flange on the jaw 25 extends beyond that on the jaw 26 to provide a broad seat to receive the canbodies as they are delivered into the machine. It will also be noted that jaws 25 have a rearward obliq ue extension 50 to support the slidable jaw when it is open to its fullest extent.

As shown in Fig. 13, the shaft for carrying the molds Inay be round its entire length, may be keyed, as at 51, in its socket in the revoluble plate 19, and provided with a round collar carrying' the cam-roll, whereby the shaft will be held securely against `turning and still may slide to advance and retract the mold.

ln operation the can bodies and heads are fed by the chute 52, arranged above the middle of the machine, into the open molds as they pass. As each mold revolves the jaws thereof close upon the can-body and force the heads thereon, and as they reach the base of the machine said jaws are opened again and permit the headed can to `fall out. Because of the simplicity of construction of the machine it is capable of heading one hundred and twenty cans a minute.

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