I VIEANS FOR TURNING AND ARRANGING CAN-CAPS;

Beit known that I, JO N T. WILMORE, a citizen of the United States, city and county of Denver and State of U010- rado, have invented certain new and useful for Turning and do declare the and exact deas will enable Arranging Can-Caps; and I following to be a full, clear,

SGllPtlOiiOf the invention, such others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in apparatus for arranging can-caps in uniform When these caps are applied by machinery, it is essential to the suc-- ranged in a magnet-carrying 'can be carriedupwardly to a sition the magnet-car to t - event the latter drop downward y cess of the operation that they certain position. i The caps in their original position aremiscellaneous y arranged; and the object of my improved construction is to brin about uniformity of position. n accomp ishing this object I use a rotary cylinder containin interiorly-projecting relatively shallow r1 s of such height that when the can-caps are in one position they will slide down over the ribs, while when they are in another position they will be caught by the ribs and carried upwardly on one side of the rotating cylinder. Mounted exteriorly upon this cylinder are-magnets carried by a swingin frame, and --hese magnets are so arran 91% that when the hinged ames reach certain positions in their circuit or revolution they fall away from the cylinder, while when in certain other positions they engage the exterior shell of the cylinder and act upon the cancaps to hold the latter in position until they position above. The construction-is so ara conveyer-belt. I

the caps reach this poranged that as soon as frame iscause rave outwardly fromthe cylinder a suflicient distance to prevent the etisin from acting on the ca. s, in which upon the belt conveyor. The principle of my improved construction consists inthe fact that when the convex side or outer surface of the ca s is turned toward the inner wall cy inder these caps will slip over the short interiorly-projectmg ribs and ass downinto thelower :part of t e rotating Specificationof Letters Patent.

1 cylinder before they are carried upwardly l far enough on one side of the cylinder to bring them within range of' the magnets. I When, however, the positionof the can-caps is reversed'and their inner or flanged surface l engages the inner wall of the cylnder on the upwardly-moving side, the interiorly-pro- ,iecting ribs will support the caps independent y of the magnetic influence until the caps l are carried upwardly within range of this influence, and when once the magnets act upon the caps this influence continues in force until the caps are carried to a position immediately above the belt conveyor. 1 It is evident that when the can-caps are in 1 position to slip downwardly past the ribs, as heretofore explained, that in order that these caps may finally turn to to be acted on by the magnets their original all be ar-l position in the cylinder must be changed.

order to accomplish this, I place interiorlyprojecting strips intermedia e the shallow ribs, the said strips being considerably wider than \he ribs, whereby a number of the cancaps after they slip past the shallow ribs are being continually carried upwardly and released, whereby there is a tendency, to tip them over or change their position as they drop downwardly into the cylinder. In this way eventually all the caps are proper position to be acted on by the exteriorly-located magnets. I

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment. thereof. In the drawing, Figure 1 is a side elevation of my-improved can-cap-manipulating construction.. Fig. same looking in the direction of the arrow in the features in the plane of the section being shown in elevation. Fig: 4- is a vertical l cross-section of the construction. Figs. 5 l and 6 are fragmentary views illustrating the operation of the device. Fig. 7 is an enlarged fragmentary detail view shown partly in section.

The'same reference charactersindicate the same parts in all the views.

Let the numeral 5 designate a rotary cylinder supported by rotating wheels or disks 6, mounted on shafts 7', journaled in the framework 8, located at each end of the cylinder.

the proper position 2 is an end elevation of the turned 10 the tal diameter on the upwardly-moving side of cylinder, m-eording to the formed, while intermediate or equidistant between each pair of these ribs is located an interiorly-projecting plate 15, the said plate being considerably wider or deeper than the said ribs.

EXteriorly mounted upon the cylinder is a number of frames, which may be designated in their entirety by the numeral 16. Each of these frames consists of two parallel arms 17 connected by a rod 18. The end arms 17 are pivotally connected to lugs 1.9,formed on the I exterior surface of the cylinder. As shown in the drawing, each one of these swinging or pivoted frames is so arranged that the rod 18 whenassuming its posit-ion nearest to the ex terior surface of the cylinder occupies a position slightly above one of the ribs 14 on the upwardly-moving side of the cylinder. When the device is in use, it is assumed that the cylinder is rotated in the direction indicated by arrow (1 in Fig. 4.

Mounted upon each rod 18 is a series of permanent magnets 20, which are arranged to engage the exterior surface of the cylinder as they approach the extremity of a horizonthe cylinder: The point where magnets first engage the outer surface of the cylinder on the upwardly-moving side thereof is approximately that indicated by the arrow O in Figs. 4., 5, and 6. The structure should be so regulated that this point shall. be located to bring a can-cap 29, carried upwardly by a rib ll, within the influence of the magnetic force before the cap has been carried upward ly far enough to tip over and fall below a horizontal diameter of the cylinder.

It will be understood that the pivoted magnet-car;ring frames 16 are free to swing by grnvitr either toward or away from the position of the latter. in order to limit the outward-swing of the l1lagnetscarrving rod [8 from the cylinder when the frames 16 are in the position shown at the lower left-hand side of Fig. '4 and also at the bottom of said figure, each arm L7 of the frame is provided with a tailpiece 17, which when the rod 18 has: moved outwardly a sufficient distance to prevent the magnetic force from acting on mder engages the cylinder and prevents farther outward movement.

Mounted upon thce'nd frames upper extremities are two wardly-projecting pieces :21,

8 at their stationary 111- provided with l l l l l r l l l l l l l l l l t l f from the strips 15. the caps within the ertparts 22 extending at right angles to the parts 21 and forming cams adapted to pass Jeneath the rod 18 of each magnet-carrying frame and raise the rod and its magnets far enough from the outer surface of the cylin der to release the can-caps when they have assumed the position at the upper extremity of a vertical diameter drawn through the cylinder, causing the can-caps to fall. Suitably mounted directly beneath and a short distance from the top of the cylinder and passing through the same is the endless conveyer 12, which receives the can-caps and carries them along in the position or approximately in the position shown in Fig. 1.

After releasing the caps at the top of the cylinder the magnet-carrying frames move downwardly and perform no function on the downwardly-moving side of the cylinder. In fact, the magnet carrying rods of these frames fall away-from the outer surface of the cylinder as they move downwardly and remain in this outer position until they have been car ried upwardly a suitable distance on the upwardly-moving side of the cylinder, as heretofore explained.

W'hen the apparatus is in operation, the can-caps are poured into a sort of hopper 25, whereby they are delivered to the lowest part of the inner surface of the cylinder. Then as the latter continues its rotary movement these caps are carried upwardly on the. upwartlly-moving side of the cylinder, and it is supposed to always happen that a number of these caps will accidentally assume a position with their flanges pointed outermost and occupying a position above a rib 14 as the cylinder moves upwardly. Now the caps that are in this position will be carried upwardly by the rib 14 until they come within the influence of the magnets 20 of a rod 18, and consequently will be held in engagement with the inner surface of the cylinder until they are carried upwardly and dropped upon the conveyer 12. Meanwhile it is also assumed that a number of the caps will occupy a reverse position-that is to say, with their curved or outer surfaces outwardly-in which event they will be carried up a short distance by the short rib 14, but not far enough to come within range of the magnetic force before they will slip downwardly over the rib 14, as shown in Fig. 5. In this event they will be caught by the strip 15 next below and carried upwardly and again thrown down, whereby they are caused to assume a different position, since the tendency s to turn over the caps as they fall In this way in pracliee it always happens that a number of the caps with their flanges directed outwardly against the inner surface of the cylinder are caught by each rib H as it passes upwardly. and the result is that each one ofthese ribs carries l a number of can-caps upwardly during each range of the to perform the function stated.

Attention is further called to the fact that the ribs 14 and the strips 15 may be termed rabbles. i

It must be understood that I do not limit 'myself to the use ofmagnets as an element of the structure, as I am aware that other means may be employed to aid the ribs, rabbles, or projections of the rotary device in the performance of the can-cap-assorting function, though at present I consider the magnets the preferred construction.

Having thus described my invention, what I claim is 1. The combination of a cylindrical receptacle, a magnet-carrying frame exteriorly mounted on and arranged to swing toward and away from the cylinder by gravity, a rib mounted on the inner surface of the cylinder and arranged with reference to the exteriorlylocated -magnet-carrying frame whereby when can-caps are in suitable position within the cylinder, theywill be carried upwardly by the rib until they are brought within by the latter a predetermined distance.
