CAN-CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 477,575, dated June 21, 1892.

Application filed March 7, 1892. Serial No. 424,023. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. PECK, of Brewster, in the county of Putnam and State of New York, have invented a new and Improved Can- Orimping Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved can -crimping machine which is simple and durable in construction, very effective in operation, and designed for rapidly and effectively crimping the heads or covers of cans onto the can-bodies.

The invention consists in certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement with the can in section. Fig. 2 is a sectional side elevation of the same. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. 4 is a face view of the mechanism for actuating one of the dies and imparting motion to the can-carrier. Fig. 5 is a face view of the central portion of the carrier and the mechanism for imparting an'intermittent rotary motion to the same, and Fig. 6 is a sectional side elevation of the cam for actuating the carrier-locking mechanism.

The improved can-crimping machine is provided with a suitably-constructed frame A in the upper part, and on one side of which is journaled the shaft B, provided with a pulley 13, connected by belt with suitable machinery for imparting a continuous rotary motion to the said shaft B. On the inner end of the latter is secured a die 0, made in the shape of a disk and having a beveled rim 0, as is plainly shown in Figs. 1 and 2. Opposite this die 0 is arranged a similar die D, also provided with abeveled rim D and mounted to rotate loosely on the inner end of a shaft E, journaled in suitable hearings on the frame A and having its axis arranged in line with the axis of the shaft 13. The beveled rims O andD of the dies 0 and D face each other, as is plainly shown in the drawings, and the said rims are adapted to engage the covers F and F re-.

ers being provided with external flanges fitting over the exterior of the can-body, while the middle portions of the covers are beveled to correspond approximately with the bevels of the rims C and D of the dies 0 and D. The can-bodies F, with the covers F and F in place, are held in a carrier G, mounted to turn loosely on a shaft or spindle ll, supported in suitable bearings A and A in the main frame A. The carrier G is preferably made circular and provided with side flanges formed with longitudinal recesses G, arranged in a circle concentric to the shaft H and adapted to receive the cans delivered to the carrier from an inclined chute I, located at one side of the carrier, as is plainly indicated in Figs. 1 and 8. A similar chute 1, arranged on the opposite side of the carrier G, serves to carry off the crimped cans.

In order to crimp the straight flanges of the covers or heads F and F beveled wheels J and J are employed, located at opposite faces of the carrier G and journaled-in brackets J ,-supported from the main frame A. The beveled wheels J and J are adapted to engage the fianges of the covers F and F respectively, and their bevels extend in line with the beveled rims G and D of the dies C and D. The carrier G has an intermittent rotary motion, so as to bring a recess carry ing one of the cans in line with the dies 0 and D to permit the latter to engage the covers F and F of the respective cans. The chutes I and I are arranged on the sides of the carrier, while the diesC andD are located on top, so that a can is always delivered into ohe of the recesses G during the time the carrier G is at a standstill and while the dies C and D and. wheels J J crimp the can in the top of the carrier. After the can is crimped it is carried to one side and is finally delivered to the chute I, which latter is located in such a position with relation to the carrier that the can is held in an intermediate position after crimping and before delivery to the said chute I. (See Fig. 3.)

On the outer end of the shaft H is mounted to turn loosely a gear-wheel K, in mesh with a pinion L, secured on a shaft L, mounted to turn in suitable bearings on the main frame A and carrying a pulley L connected by a belt with other machinery for imparting a :ontinuous rotary motion to the said shaft L, so that the motion of the latter is imparted to the gear-wheel K by the pinion L. On the outer face of the gear-wheel K is arranged a cam K, on which travelsa friction-rollerN,journaled in an arm N, attached to the outer end i of the shaft E carrying the die D. A spring E is coiled on the shaft Eand presses with one end against a collar E held on the said shaft- E, and with its other end presses on one of the bearings of the said shaft. WVhen the gearwheel K is rotated, the cam Kacts on the wheel N, so as to move the arm N outward, whereby the shaft E, with the die D, is moved longitudinally. This motion of the die D disengages the latter from the cover F so that the can-body F is released after it is crimped to permit the carrier G to carry the crimped can-body forward to an intermediate position. A return movement ofthe shaft E and die D is accomplished by the spring E, which is compressed on the outward sliding movement of the shaft E. On the inner face of the gearwheel K is-formed a cam-groove'K engaged bya friction-roller O, journaled on a crankarm' 0, secured on the outer end of: asha-ft P, extending longitudinally and mounted to turn. in suitable bearings in the frame A. On the inner end of this shaft P is secured a crank-arm P, carrying a pawl P engaging a ratchet-wheel G formed. on one face of the carrier G. When the gear-wheel K is rotated, the friction-roller 0 during part of the revolution of the said wheel imparts a swinging motion to the crank-arm 0, so that the shaft P isturnedand by itscrank-arm P and the pawl-P causes the carrier G to turn on the shaft H.-

As shown in the drawings, the proportion between the several parts is such that at every revolution of the shaft K the carrier G is given one-sixth turn, so as to bring the corresponding recesses G into register with the chutes I and I and the dies 0 and D.

In order to prevent the carrier G from turning during the operation of crimping, the fol-- lowing device is provided: On the face of the carrier G- opposite the ratchet-wheel G is formed a seriesot' notches G corresponding in number to the. recesses G and located in; the said carrier around the shaft G, as is plainlyshown in Fig. 3. A lug Q is adapted to engage one of the said recesses G at a time, the said lug being formed on a rod Q, mounted to slide longitudinally in a groove formed in the shaft H. rod Q is provided with a lug Q projecting from'the surface of theshaft Hand adapted to engage an incline R, formed on a sleeve R, attached to the gear-wheel K. Thus when the latter is rotated thev sleeve R engages with: 3

its incline R the said'lug Q ,;so that the latter is pushed to the right,,moving the rod Q and the-lugQ in the same direction,whereby the latter is disengaged from the respective notch G and the carrier G is unlocked to be rotated by the pawl P engaging the ratchet- The outer end of this Q wheel G as above described. A spring S presses on the lug Q, so as to insure a return movement of the rod Q and also to hold the lug Q in position in one of the recesses G as above described. 7

The operation is as follows: When the shafts B and H are rotated, an intermittent rotary motion is given to the carrier G, as described. iThe can-body passed into one of the recesses G at the chute I is carried forward by the carrier G at the next movement, so as to be lbrought opposite the dies 0 and D, of which the latter is then in an outermost position and is returning to engage the cover F as soon as the carrier G has come to rest. The rotary motion of the die 0 now imparts a rotary motion to the can, so that the-die-D also revolves. At the same time the outer surfaces of the flanges of the covers F andF- are held in contact with the bevel-wheels J and J, respectively, so that the latter press theflanges inward toward the beveled rimsOand D of the dies Gy and D, causing the outer edges of the can-bodyF to be bentlikewise, asis plainly shown in Fig. 2. It is understood that the beveled rims O and D of the. dies 0 and D act as anvils for the crimping-wheels J and J. During the process of crimpingrtlie: shaft .13, and consequently the dies 0 and Band "the can, are revolved a numberof time's, after which the cam K acts on the. frictionroller N to: cause the die D to'slide outward ;away from the crimped cover-F The canis 2 thus released, and the carrier G now receives a forward motionin the manner. previously ;described,.so that the crimped can is moved 1 to anintermediate position and an uncrimped oan is brought to the top in line withthe dies 11C and D. At thistime the die D-returns-and the abovedescribed operation is repeated. iIt is understood that during the crimping process above described thecarrier G remains-in ia locked position, held by the lug Q engagling acorresponding recess G Prev-ions to imparting motion to the carri'er'Gt-he rod Q iis moved to theright to disengage thelug Q from the recess, after which; the pawl? acts 5 on the ratchet-wheelG to move the carrier-forward, as previously described. Thecrimped lOELIl is moved to an intermediate position pre- {permit the can to come to a rest after being crimped, asthe. said can continues torevolve :fora short time after being crimped, this'be- 1: ing caused by the action of the revolvingidie C.

It will be seen that thismachin'eis very simi'ple and'dura-ble in construction, automatic in a operation, and arranged to securely crimp the flanges of the covers or headsonto the canzbodies in the manner above described.

Having: thus described my invention, I iclaim as new and desire to secure by Letters Patent- 1.
