CAN TOPPING AND WIPING MACHINE.

SIECiFICATION forming part of Letters Patent No. 652,581, dated June 26, 1900.

Application filed March 1, 1900. Serial No. 6,965. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES H. AYARS, a citizen of the United States, residing at Salem, in the county of Salem and State of New Jersey, have invented certain new and useful Improvements in Can Topping and W'iping Ma chines, of which the following is a specification.

My invention relates to certain improvements in can topping and wiping machinery, the object of the invention being to provide automatic mechanism for intermittently conveying unsealed cans previously filled with vegetables or fruit to a plugger, which pushes the contents down from the mouth of the can. The can is then moved beneath a brush, which has its front edge recessed or hollowed out and which brushes any of the contents which may have been forced by the plugger out and upon the cans top back into the can, and then to a reamer or topper, which removes the contents of the can from contact with the edge of the cans mouth to prevent chilling of the solder by which the cap is secured. The can then passes successively beneath one stationary and four revolving brushes, which wipe all moisture from the top of the can and dry it preparatory to applying the cap.

Referring to the accompanying drawings, Figure 1 is a side elevation of the machine.- Fig. 2 is a plan View of the belt-driven pluleys at the top of the machine. Fig. 3 is an enlarged sectional view of my reamer. Fig. 4 is an enlarged plan View of the recessed brush and several cans beneath.

A is the frame of the machine, which frame is provided with suitable bearings and guides for the moving parts.

B is a vertically-movable table with horizontal guide-rails ct on along each side and supported by two spiral springs Z) Z), through which pass vertical guide-rods c c, said rods having their upper ends fastened to the under side of the table B, their lower ends being free to move vertically in the guides d d, which are fastened to the frame A. A loose collar (designated on one rod 6 and on the other e) is placed upon each guide-rod below the said spiral spring and over the forked ends of the two levers ff, extending from the center in opposite directions, and a collar e e is securely fastened to each of said rods just below the forked end of said lever. The said two levers f f are pivoted at g g, their other ends at the center being hinged at h h to two short linkst't", which are in turn hinged to one end of the leverj, whose other end is hinged at k to a bracket on the frame. The said lever has a roller Z mounted near its center, upon which the cam m bears.

The horizontal shaft 0 supports and r0- tates the three cams on m m and is driven by the gear at, which in turn is driven by the pinion n, mounted upon the shaft 0, which shaft also drives the bevel-gears n n and is driven by the wheel at". The shaft C' supports the lever P, which is vibrated by the cam on coming in contact with the roller Z and spring b transmitting an intermittent lateral motion to the horizontally-guided can-pusher bar D through the lever f and adjustingscrew E. The cam on acts upon a bar j, which at one end is hinged to the bracket 7.: on the frame and at the other end to the vertical rod 0, which operates the reamer, as will presently be described. The vertical shaft 0 driven by the said bevel-gear n drives a pulley P at the top of the machine,from which an endless belt S drivesall the other pulleys P P P P P P, the belt being wound in the direction shown in Fig. 2. The pulley P drives the reamer. Pulleys P P P P drive revolving brushes r r 7' r Pulley P is an idle pulley for tightening the belt.

r is a stationary brush whose front edge is recessed, preferably into V shape, and which is supported by adjustable brackets fastened to the table B, and r is another stationary brush similarly supported.

2) is a plugger fastened to the top part of the frame of the machine and depending downward.

Referring to Fig. 3, the reamer consists of a vertical tube q, driven by thepulley P, which tube supports and rotates the pivoted plug .9, projecting from the bottom. A second tube q is within the upper part of the tube (1 and is revolved with the tube g by engaging with the upper end of the plugs, which projects upward between the lugs t t within said inner tube. The inner tube is vertically movable and is depressed by the action of the cam m through the bar 3, vertical rod 0,

and lever 0', which is pivoted to the bracket 0 A rigid bracket to depends from the top of the frame and has on its bottom a disk 10, preferably of rubber, with a central hole. It also has four small tapered lugs or pins y to center the can-top. The reamer 3 projects down through the disk 10, against which the top of the can z presses while the operation of reaming is going on.

The operation is as follows: Unsealed cans, filled with fruit or vegetables, being placed upon the table 13 at the end 1) are shoved along the table at each revolution of shaft 0 a distance equal to the diameter of the can. Cans are placed upon the table at the rate of one can for every revolution. of shaft C by means of the shover D. To make the operation clear, take the case of a single can and follow the successive operations: The shaft 0, revolving right handed the cam m, first acts, causing the can-pusher bar to shove the can forward. Supposing the can to be now under the pluggerp,the cam m,actin g in its turn, raises the table B and can, causing the plugger to compress the contents of the can, forcing the contents down from the mouth. It is to be understood that while the table is in its elevated position other cans which have preceded the one under discussion are being reamed and brushed at the same time that the one under consideration is being plugged. After a can has been plugged the table is lowered by the cam m having completed its operation. By the continuous rotation of shaft 0 cam m is again brought into operation, and after two cycles of operation the can,having passed under the recessed brush 1", arrives under the ream er 8. Then as the table again rises by the action of cam m the can is pressed up in contact with the rub-. ber disk 10. The cam m now acts, depressing the inner tube q of the reamer through the tinuously rotating, it removes the contents of the can from contact with the top of the same around the edge of the mouth. Cam m having now passed by, the inner tube q rises, and the reamer resumes its normal position. The can next passes by successive stages beneath the stationary brush "1' and each rotating brush in turn. The distance between each rotating brush and the plugger and reamer is a multiple of the diameter of the can and is also adjustable to suit cans of different diameters. The action of the springs 19 b is chiefly to allow for inequality in height of cans, thus compressing the springs instead of crushing the can.

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

1. In a canning-machine the combination spiral spring around each of said vertical rods and its lower end resting on said loose collar; and two levers, f, f, below the table, each lever having one end below a different one of said loose collars.
