SPECIFICATION forming part of Letters Patent No. 436,784, dated September 23, 1890.

Application filed March l5, 1890.

.To all whom it may concern:

Be it known that I, JOHN G. IIODGSON, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Im- Y provement in Crimping-lvlachines for Sheetj Metal Cans, of which the following is a speci- A cation.

Myinvention relates to machines for crimping sheet-metal cans or other vessels.

The object of my invention is to provide what I term a universal crimping-machine, or a machine which may be readily adapted to crimp cans of different sizes or shapes.

My invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specication,and in which similar letters of reference indicate like parts, Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a front end view. Fig. 3 is a rear end view or sectional elevation looking from the line 3 3 of Fig. 1. Fig. 4 is a detail sectional View showing the vertically-adj ustable slide to which the rollerframe is pivoted. Fig. 5 is a section on line 5 5 of Fig. l. Fig. G is asect-ion on line 6 G of Fig. 5. Figs. 7 and 8 are sectional views showinga can before and after the crimping operation.

In the drawings, A represents the frame of the machine.

I3 is .the lower crimping-roller shaft journaled in fixed bearings B B on the frame of the machine. v

C is the driving wheel. The revolving shaft B is furnished with a crimping-roller b, adapted to be inserted within the can. The roller l) is detachably secured upon the end of the shaft B, preferably by means of screwthreads o', so that this crimping-roller may be removed and replaced by others of a different diameter or shape, according to the particular size of the can and shape of crimp designed to be operated upon or produced. The crimping-roller h is or may be furnished with abeveled flange b2. rIhe form of this 5o flange will of course vary, according to the particular shape of seam desired to be crimped Serial No. 344,017. (No model.)

The shaft B is also, preferably,

or produced.

a beading-roller b3,

or may be provided with having a beading-flange bl. The roller h3 is likewise removably secured to the shaft B, so that it may-readi] y be removed and replaced by other beading-rollers of a different diameter or shape.` The roller b3 is preferably thus removably secured to the shaft B by means of an eccentric groove b5, cut upon the inte- 6o rior of the roller b3, in which groove is placed a short pin or wedge D, which operates to tighten the roller Z13 upon the shaft B when the shaft B is revolved.

D is the shaft of the upper or movable crimping-roller. The shaftD is journaled in suitable bearings D D on a pivotal and'vertically sliding or adjustable bar or frame F. The shaft D is furnished with a removable crimping-roller d, having a groove d and a 7o flange d2, adapted to lit over and form a support for the end ot' thecan during the crimping operation. The roller d is secured t-o the .shaft D re ovablygfand preferably by means of screw-thr rtds d3, the saine as the roller b to its shaft, the threads being right and left hand, as shown, to prevent unscrewing. The shaft D is likewise provided witha beadingroller d4, having a beading-groove d5, corresponding to the beading-flange b4 on the roller 8o b3. The roller d4 is removably secured to its shaft D, and preferably by the same means as above described for securing the roller b3 to its shaft B. The sliding and pivotal bar or frame is pivoted or journaled upon a slid- 8 5 ing or adjustable block H, which is adj usted up and down in the guide or slotted standard II by means of the adjusting-screw h, which is furnished with a hand-wheel h'. The front Y end of the bar or frame F moves up and down 9o in the guide or slotted standard G. The upward movement of the bar or frame F is limited by an adjustable stop g, secured in the standard G by a set-screw g', which enters depressions or recesses in the stop-barg. The front or free end of the pivotal and sliding or adjustable crimper-roll-carrying bar F is operated so as to force the crimping-roller d against the crimping-roller b by means of a treadle or lever K, which is connected to the roc bar F by a linlt K. The link K is made in two parts adjustably connected together by a set-screw Zc,wl1ich passes through the sleeve part K2of thelink and engages the other part K thereof. The pivotal and vertically-moving crimping-roller shaft D is driven from the shaft B by means of the gears P Pl on the shafts B and D, respectively, and the intermediate gears P2 P5, which are journaled on an arm or lever P4 pivoted to the shaftB, the free end of which is adjusted in proper position in relation to the distance between the shafts B D by means of a slotted standard P5 and a set-screw p, which passes through the slot p of the standard P5.

T is a gage secured to the rod t, which is adj ustably fixed in the frame A by the setscrew if. The purpose of this gage is to afford a stop for the end of the can to abut against during the crimping operation.

In operation a can-such as is represent-cd, for example, in Fig. 7-is placed over the roller b, with its open end abutting against the gage T. The operator then, with his foot upon the treadle K, depresses the roller-carrying bar Fand forces the crimping-roller d against its mate b. At the same time and bythe same operation the beading-rollers d and b5 will form a bead in the can, if itis desired to bead the can also. If not, the beading-rollers will of course be removed from the shafts B and D. To operate upon cans of larger diameters, the rollers b CZ and b5 b4 will be replaced by other or similar rollers of a larger diameter. The pivot-block H is adjusted to the proper height by means of a screw 71y to keep the shafts B D parallel when inoperation, the stop g and the link K being also adjustable to suit the diameter of the can operated upon. The gage T may also be adjusted in and out for operation upon cans of different lengths. By means of the eccentric groove and the fastening pin or wedge for securing the beading-rollers in place on their shafts these beading-rollers may be secured at any position longitudinally on their shafts, so that the bead may be produced at any point desired in the can. By moving or adjusting the lever P5 the gearing P P2 P3P4 will properly mesh together whatever may be the relative position to which the shaftD is adjusted by its sliding pivot-block. For very small cans the gears P and P may mesh directly together, the gear P3 beingthrown out of mesh by the lever P4. The pivotal frame or bar F is retracted by a spring 7s. The shafts B and D are provided with adjustable collars B2 and D2, fixed in place by set-screws, so that the shafts B and D may be slipped longitudinally when necessary to accommodate cans of greater length: The shafts B and D are splined, so that the may slide through the gears P and P.

I claiml. The combination of frame A, shaft B, j ournaled thereon, furnished with a crimpingroller l), sliding bar F, its guides GH, sliding pivot-block H, adjusting-screw h, crimpingroller shaft B, journaled on said bar F and furnished with crimping-roller b, operatinglever K` adjustable connecting-link K', and an adjustable stop g, said shafts B and D being furnished with driving-gears, in termediate gears, and a lever upon which said intermediate gears are journaled -for adjusting their position, substantially as specified.

2. The combination, with a crimping-roller and its shaft journaled in fixed bearings, of a pivotal and vertically sliding or adjustable crimping-rollerand its shaft, driving-gears o each of said crimping-roller shafts, and a lever carryingintermediate gears for communieating motion from one of said shafts tothe other in its different positions oradjustments, substantially as specified.

3. The combination, with a crimping-roller shaft B, journaled in xed bearings1 of crimpl ing-roller shaft D, journaled on vertically- 85 i sliding and pivotal bar F, sliding pivot-block H, means for adjusting said block, an operati iig-lever having an adjustable connection with said pivoted bar F, driving-gears on said shafts B D, and an adjustable lever carrying intermediate gears, substantially as specified.

et. The combination,with a crimping-roller shaft B, journaled in fixed bearings, of crimping-roller shaft D, journaled on verticallysliding and pivotal bar F, sliding pivot-block H, means for adjusting said block, an operating-lever having an adjustable connect-ion with said pivotal bar F, driving-gears on said shafts B D, an adjustable lever carrying intermediate gears, and a gage for the end of the can to abut against, substantially as specified.
