CAN-COVER-REMOVING APPARATUS.

' Application filed March 4,

To all whom t may concern.'

Be it known that I, JAMES M'. RUDE, a citizen. of the United` States, residing at Covington, in the county of Kenton and State of Kentucky, haveinvented certain new and useful Improvements in Can-Cover- Removing Apparatus; andI do hereby declare the following to be a full, clear, and

exact description of the invention, suoli as will enable others skilled in the art to 'which it appertains to make and use the same.

rlhis invention relates to improvements in abrading machines, and more particularly to such as are adapted for use in treating usedv cans for their recovery.

vThe object in `view is the provision of means for quickly, easily and inexpensively removing injured covers from used cans and leaving the cans in proper condition for further treatment for re-use.

With this and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of partsas subsequently specified and claimed.

VIn the accompanying drawing,

Figure 1 is a view in side elevation ofan apparatus embodying the features of the present inventioinparts being broken away.

Fig. 2 is a substantially vertical section taken on the planes indicated by line 2*2 of Fig. 1, and looking in the direction indicated by the arrows.

Fig. 3 is an enlarged', vertical central section throughy a part of the structure on the plane substantially as indicated by the line l3--3 of Fig. 1, parts being seenin elevation.

Fig. is a fragmentary, detail view, partly in elevation and partly in section, showing the action of the face of the emery wheelonpthe edgeA offthe can.

-Referring to the ldrawing by numerals, 1, 1 indicate standards having slide- bearings 2, 2 in. which is mounted the reciprocating shaft 3 which is held againstrotation in. any suitable manner, asbybeing keyed to its supl )Orts 2 orb `the aresence of an o eratino' l) O lever 4 extending through a slot 5 in the shaft. A pin 6 'extends through the shaft andthrough a slot 7 in the lever 4f fortra nsmittingy motion from the lever to the shaft 3.

Detachably mounted on one` end of the shaft3 is a saucer-like can-receivingplatc consisting of a disk-shaped body 8 having a forwardly inclined flange 9 and opened Specification of Letters Patent.

vcentrally forthe admission of the end of Vears 12 spaced uniformly about the iiange and varying in number according to the work to be done and especially as governed by the size of cans to be treated. A preferable number of pairs of ears 12 and their cooperating parts consists of-four, as indicated in the accompanying drawing. Between the ears of each pair 12 extends a lever 13, each lever 13 being pivoted at 111 to the respective pair of ears, and extending rearwardly past its pivot point to a trip-engaging end 15. The lever 13 extends past its pivot .141 in the opposite direction and is bent about the fiange 9 and terminates in an arcuate gripping plate 16. Each gripping plate 16 is preferablylined with a sheet 17 of rough material, such as asbestos, or the inner face of the plate may simply be knurled or otherwise roughened so as to afford aneffective gripping inner surface for the plate. Springs 18 are iiXed to the rear face of plate 8, one being provided for each lever 13 and located for pressing the rear end of the lever rearward, which pressure results in pressing the gripping plates 16 radially inward'.

f Fixed to that standard 1 which is nearer the disk 8 is an annulus 19 arranged in the path of rearward travel of the rear ends, that is the ends 15, of levers 13 so that when the shaft 3 is moved-rearwardly the said ends strike the annnlus and the further movement of shaft 3 by drawing thedisk 8 nearer the annulus 19 effects a movement of the levers 13 equal tov movingfthe ends 15 forwardly. This results in radial out- ,ward movement of the gripping plates. 16

against the pressure of springs 18. The openingof thc gripping plates 16 in this way enables the ready introduction of a can between the plates 16V and in conta-ct with plate S. T he operator in placing the can 2O does so manually and finds that the inclined 'flange 9 materially assists in guiding the can to a relatively central. position in corcoincident with the axis of can 2O while the i can is being operated upon.

The lever Il may be mounted in any appropriate manner, as by being pivoted at 23 to the framework 211 to which the standards 1 are fixed. A spring 25 preferably engages the lever -l and is tensioned to draw the same rearward.

In operation, a can is applied as above described and the operator grasping the handle 211: of leverl presses the same forward until the edge of the end of can 20 strikes the face of emery wheel 21. That end of can 20 is presented to the emery wheel which carries the injured cover. By injured cover is meant that closure of the can which has been punctured or cut away more or less for removal of the contents of the can. The pressure on the lever 2% by the hand of the operator is continued until the emery wheel has out its way through the bead-like portion at the edge of the injured cover of the can so that the parts take the position indicated in Fig. i where the cutaway portion of the cover is indicated in dotted lines at 26. As soon as this point is reached, the lever t is allowed to be drawn back by the spring 25 and the can 20 released, a new can being applied and the operation repeated. its soon as the portion 26 is cut away the main portion of the injured cover of the can, that is the portion extending across the area surrounded by the can body, will fall away from the can and leave the parts free for access to the interior of the can. The can is then ready for further treatment in the way of cleansing for re-use.

A collar 27 surrounds the shaft 3 and is adjustably connected thereto by a set screw 28 and the shaft 3 is preferably provided with graduations 29 scaled to agree with the varying lengths of cans. The collar 27 is designed to be set at any given point on tl ie graduations 29 according to the particular can to be operated upon, and the parts are proportioned to cause the outer face of the collar to strike the bearing 2 when the portion 26 of the can 2O has been completely ground off. Thus the operator in pressing the lever l forward does not have to give atl tention to the extent to which the grinding operation has proceeded. Ile merely presses the level' forward until the collar 27 strikes the end of the bearing 2 and then pulls the lever backward again to release the can. Supplementing the stop provided by collar 27 is a set screw 30 threaded through a pro jection 31 extending laterally from the lower portion of lever 4, the screw being designed to strike a part of the frame 24: when the lever 4C reaches the forward limit of its movement. The screw 30 is utilized to relieve the collar 27 from excess strain and is adjusted proportionally to the adjustment of the collar 27, whenever a change is made for the purpose of operating on cans of different length. It should be obvious, of course, that either the -stop 27 or the stop provided by screw 30 may be utilized without the other, but the use of both tends to increase the eiiiciency of the machine, insuring against the injury that might result from failure of the stop to limit the movement of the shaft 8. It is apparent, of course, that if the shaft 3 is moved forward too far, more than the portion 26 of can 2l will be removed and the can will be proportionally weakened. lVhat I claim is 1. In can cover removing apparatus, the combination of a reciprocating shaft, canengaging means mounted thereon adapted to move a can to a position for having its cover severed, and an adjustable stop for limiting the movement of the shaft.

2. In can cover removing apparatus, the combination with a rotary abrader, of a reciprocating non-rotary shaft movable toward Vand away from the abrader and adapted to press a can toward the abrader, and means for limiting the movement of the shaft toward the abrader.

3. In can cover removing apparatus, the combination with an abrader for cutting away a can cover, of a plate for receiving the 'end of the can opposite the cover to be removed, means for advancing the plate toward the abrader, and means for gripping the can while thus advancing.

et. In can cover removing apparatus, the combination with an abrader for cutting away a can cover, of a plate for receiving` the end of the can opposite the cover to be removed, means for advancing the plate toward the Vabrader, and means carried by the plate for gripping the can while thus advancing.

5. In can cover removing apparatus, the combination with an abrader for cutting away a can cover, of a plate for receiving the end of the can opposite the cover to be removed, means for advancing the plate. toward the abrader, levers pivoted to the plate and having can gripping terminals, and springs pressing the levers in position for causing the gripping terminals to engage and retain a can.
