Refining 'oampany, Incorporated, New York, N. Y., a corporation of New York 8 Claims.

This invention relates to article handling apparatus, andmore particularly to apparatus for separating enclosing parts of articles from parts enclosed thereby.

In order to reclaim metal forming the shells of worn out dry cells, battery elements contained in such shellsmust be removed therefrom. Previous to this invention, such elements were removed by hand or were pressed from the shells by apparatus requiring a large amount of manual handling of the batteries in its operation which thereby rendered the cost of such reclamation prohibitive.

It'is an object of this invention to provide new and improved article handling apparatus. 7

One device embodying the invention comprises a reciprocal pneumatically actuated plunger, a rotatable carrier positioned beneath the plunger, which carrier is provided with a plurality of compartments for holding dry cells to be operated upon, a wall adjacent to a portion of the circumference of the carrier, a plurality of fins extending from the wall towards the carrier and so positioned that one end of each of the fins is nearer the carrier than is the other end, whereby the dry cells are firmly held in position in the compartments, means for intermittently rotating the carrier so as to position the dry cells beneath the plunger, and a finger so positioned as to disengage the stripped shells from the compartments.

A complete understanding of the invention may be obtained from the following detailed description of one embodiment thereof, when read in connection with the appended drawings, in which Fig. 1 is a fragmentary, top plan view of an apparatus embodying the invention;

Fig. 2 is a vertical, partially sectional view thereof taken on line 2-2 of Fig. 1;

Fig. 3 is a horizontal sectional view taken on line 3-3 of Fig. 2;

Fig. 4 is an enlarged, fragmentary sectional view taken on line 4-4 of Fig. 1;

Fig. 5 is an enlarged perspective view of a portion of the apparatus, and I Fig. 6 is an enlarged, fragmentary perspective view of a portion of the apparatus.

Referring to the drawings, a cylindrical article carrier I0 having a plurality of U -shaped pockets I I -l 5 formed therein at equidistant points about the periphery. thereof is rotatably mounted upon a post 12 (Fig. 2) extending through apertures in a base plateie and a base is forming part of a support l5 and secured in position by means of a nut Hi. The post I2 has an L-shaped passage 11 formed therein for lubricating purposes, and a nut l-8 having a hexagonal flange formed thereon is threaded upon its upper end to secure the carrier l0 rotatably upon the post l2. The carrier I 0 is provided with an annular groove 24 formed around the periphery thereof to a depth equal to that of the pockets H-H and a plurality of horizontal arcuate fins 23-23 formed on the interior surfaces of the pockets H-i I which project into the pockets.

Each of a plurality of blocks 25-25 is secured upon the upper surface of the carrier i0 adjacent to the outer periphery thereof and approximately midway between each adjacentpair of the U-shaped pockets H-! l. The blocks 25-25 have inwardly and downwardly bevelled ends 26-26 which are predisposed sothat in going around the carrier in a counterclockwise direction, as seen in Fig. 1, the bevelled ends 26-26 will be encountered first as each block is reached. A yoke 21 (Figs. 1, 2 and 6) resting upon the carrier H] has a circular aperture 28 formed therein which surrounds the lower periphery of the nut I8. The yoke 27 also has formed therein a notch 30 and aligned bores 3l-3l, which extend outwardly from the notch 30. One end of a handle 32 is pivotally mounted upon a pin 3'! passing through the bores 3l-3I and a bore 36 formed in the handle 32. The handle 32 has a bevelled surface formed thereon, which is complementary to the bevelled ends 25-26 on the blocks 25-25. When the handle 32 is held against the carrier i6 and rotated in a counterclockwise direction, as viewed in Fig. l, the

bevelled surface 35 is brought against one of the bevelled ends 26-25 of the block 25-25 and causes the carrier to rotate around the post l2.

A generally triangular plate 38 (Figs. 1 and 2) having an aperture 49 and bores 4l-4i formed therein is secured by the nut I8 and bolts 43-43 upon the yoke 27 and upon

arcuate blocks

44 and 45 having bores46-45 therein. The bolts 43- 53 project through the bores 4I-4i and 46-46 and are threaded into apertures 41-47 formed in the base plate l3. An arcuate cam 48, having ribs 50-50 projecting from the inner periphery thereof and the ends 5| and 52 thereof beveled, is secured to the

blocks

44 and 45 by screws 55-55. The block 45 is positioned closer to the carrier i0 than is the block 44 so that the portion of the cam 48 secured to the block 45 is closer to the outer periphery of the carrier l0 than is that portion of the cam which is secured to the 'bIOck 44.

A stripper 56 (Fig. 3 and 5) having a finger 51 formed thereon is secured on the plate It by a bracket 58. The finger 51 has an arcuate surface 60 formed on the end thereof and projects into the groove 24 formed in the carriage ID with the surface 60 resting on the inner surface of the groove.

A pneumatic cylinder 82 (Fig. 2) supported by a standard 63 forming a part of the support 85 has conduits 65-55 leading (not shown) of a conventional type which is con-' nected to a supply of compressed air. The base plate i3, the base l4 and the plate 38 have aligned openings 61, $8 and 69, respectively, which are directly be actuated by the pneumatic cylinder 52. openings 61, B8 and 68 are concentric with the circular portions of when the pockets therewith.

In the operation of the apparatus described hereinabove, one of a plurality of dry cells i I-l i, for example, a flashlight cell, having its outer paper covering removed'is placed in one of the pockets H-H at the loading position, which has been designated A in the drawings. The handle 32 is moved into engagement with one of the blocks 25-25 and is rotated to rotate the carrier ii] in a counterclockwise direction, as viewed in Fig. 1, through an angle of about 60. When the handle 32 is moved into engagement with any of the blocks 25-25, the surface is pressed against the bevelled end 25 of the block and the handle 32 is thereby forced against the carrier it. During the above described rotation the dry are positioned in alignment cell H rides over the plate l5 and is carried to the position designated B where it is forced by the bevelled end 5! and the ribs iii-5E3 of the cam 48 into contact with the fins 23-23 in the pocket H in which it is positioned.

A second dry cell then is placed in the next succeeding pocket (Fig. 1) reaching the-loading position A. The handle 32 is disengaged from the block which it is engaging, is lifted to clear the block and is then rotated clockwise, as viewed in Fig. 1, until it is in a position to engage another one of the blocks 25-25. The handle 32 is then lowered into engagement with the latter block and is again rotated to turn the carrier ll! until the first-mentioned cell of the dry cells H-li is carried to the ejection station C directly beneath the plunger '53 and is inalignment with the openings 6?, (it and 55 formed in the base plate is, the base 54 and the plate 38, respectively. As this dry cell is moved from position B to the'ejection station C, the ribs 58-53 of the cam 28, which are positioned closerto the carrier H3 at the end 52 of the cam than at the end 5! thereof, will bear against the shell E2 of the dry cell and force the dry the fins 23-23 so that the fins 23-23 and ribs -56 will grip the cell sufficiently to somewhat corrugate the shell thereof and thus securely hold the cell below the plunger 78.. v

The compressed air valve (not shown) is then operated manually to cause the plunger it (Fig. 2) to be forced downward to eject the interior elements of the dry cell from the shell it thereof which is held against movement by the fins 23-23 and ribs -50. The stroke of the plunger NJ is srimciently long to permit it to remove the entire center portion of the cells frornthe surrounding shells. After the downward motion of the plunger 10 has ceased, the valve is shifted to retract the plunger.

1 finger 51 projecting into the a predetermined recess between the ribs 50-50 securely hold the shell 12 throu hout the ejecting and retracting operations.

A third one of the dry cells I l-H (Fig. 1) then is placed in the next pocket Ii and the carrier H3 is rotated until the second mentioned dry cell is directly under the plunger 10 and the ejecting operation is repeated. As the carrier it is retated, the empty shell 12 of the first mentioned dry cell is moved from the ejecting station C and is retained in the carrier l0 until it engages the groove 24 at the station D, which finger removes the shell from the carrier. As the carrier I0 is rotated between the ejecting operations, the succeeding empty shells 'IZ-IZ-are withdrawn from their respective pockets H-H by the finger 51 and are guided by the stripper 56 off the plate it into any suitable receptacle (not shown) from which they may be removed as desired for further reclaiming operations.

Large numbers of dry cells may be handled by the use of the above described apparatus within a comparatively short period of time, thus reducing the labor and expense normally required to prepare the shells thereof for reclaiming operations. The above described embodiment of the invention may be modified without departing from the spirit and scope of the invention. For example, the handle 32 may be removed and a suitable intermittent drive may be attached to the carriage ill to rotate it automatically. Also, cams may be spacedly positioned on the carriage and the operating mechanism of the air valve may be positioned in the path of the cams to automatically actuate the plunger Whenever one of the dry cells is positioned beneath it.
