FEED MECHANISM FOR ASSEMBLING-MAGHINES.

To all whom it may concern:

Be it known that I, GEoRe KIRKEGAARD, a citizen of theUnited States, residing at the city of New York, in the borough of York, have invented certain new and useful Improvements in Feed Mechanism for Assembling- Machines, of which the following is a full, clear, and exact description.-

This invention is a mechanism for feeding tsmall articles such as disks, caps, nuts, etc., to a chute or chutes for delivery to an assemgling machine or at any other point de sire One object of the invention is to pro vide such a device which shall be capable of -simultaneously feeding the articles named from two different reservoirs or piles. For instance, in the manufacture of bottle stoppers comprising a metal cap containing inside thereof a cork disk, it is desirable to feed the caps and the cork disks at about the same rate to an assembling machine adapted to bring them together in their final relation. The present invention is intended especially to accomplish this by means of a simple mechanism eflicient and sure in its operation. In the feeding of the cork disks, it is only necessary for the machine to pick up the disks one by one and deposit them into the mouth of a chute which will lead them to the assembling machine. But in the case of the metallic caps which are hat-shaped or of other irregular is required that the feeding machine shall not only pick up the pieces one by one, but that they shall be turned or faced properly before they enter the chute so that they will be properly presented to the assembling machine. My improved feeding mechanism is a single machine having the dual function of feeding the cork disks and metal caps, it being capable, in the one case, of pickmg up the cork disks one by one from the reservoir and carrying them to the mouth of a leading-off chute into which they are deposited oneafte'ranother, and in the other case, of picking up the metal caps one by one and carrying them to the mouth of a chute where in case theyjare not properly .faced or presented they will be discarded and delivered back to the-reservoir, but in case they'are roperly faced, they will enter the mouth of t e chute and pass thence machine or other point Specification of Letters Patent.

of delivery. The means for picking up the articles from the reservoirs comprises a wheel or drum provided on one of its side faces with a series of small openings through which air suction is maintained, and on its other side face with the poles of a series of magnets. One reservoir is arranged on each side of the wheel so that the suction holes and the magnet poles come in contact with the contents of the reservoirs as the wheel rotates.

Certain specific features of my invention relate to the shifting of the position of the disks or caps after they are picked up from the reservoir so that they will enter the mouths of the chutes. This feature of my invention is of considerable importance since the disks and caps are necessarily picked up and held in various positions, requiring certain straightening or shifting in order that they may enter the mouths of the chutes. All such matters will be fully described in detail with reference to the accompanying drawing, in which:

Figure 1 is a front elevation of my feeding machine; Fig. 2 is a view taken from the same point as Fig. l but showing the reservoirs 1n section; Fig. 3 is a side elevation of the feed wheel; Fig, 4 is a side elevation ofthe entire machine; Fig. 5 is a view similar to Fig. 4. but of the opposite side of the machine; Figs. 6 and 7 are partial sectional views of the feed wheel; Fig. 8 is a perspective View of the adjusting guides and chutes, and Fig. 9 shows views of themetal caps and disks. Fig. 10 diagrammatically illustrates the action of the guide 10' and shive channel upon the shives carried by the suction side of the carrier.

Referring to the drawing, 1 indicates a feeding wheel or drum mounted upon the horizontal axis or shaft 2 adapted to hero tated in the direction of the arrow by means of a belt applied to the pulley at the end of the shaft, or otherwise. Against each of the side faces of this wheel are fixed the dished plates 3, 3, in the nature of cheeks which together with the vertical faces of the wheel form an inclosure or reservoir on each side of the wheel. These plates cover a little of the wheel, leavarticlestoe fed are eposited in these two reservoirs, the metallic caps being placed in one reservoir and the cork, disks in the other.

l The shaft bearings are at 4 being a part of two chutes 11 arranged in planes parallel to the side faces of the whed and closely against the wheel-and in an inclined position. The passages through these chutes along the portions which overlap the wheel are formed on the inside by the face of the wheel itself, and on the outside by the vertical wall of the chute itself, while the bottom is formed by a filler 16 which rubs against the face of the wheel. This filling piece 16 in one instance is provided with a longitudinal groove 15 along one edge and adapted to receive the flange 30 on the edge of the metallic bottle cap (Fig. 9) when the same is properly presented to the chute. The filler 16 of the other chute is plain since it is adapted to receive the simple disks of cork 31. The upper end of the bracket 13 sustains two cams or guides 10 each of which consists of a plate arranged with its'edge against the face of the wheel and extending downwardly to a:

point adjacent to the mouths of the respective chutes. The function of these cams will be explained later on.

' its opposite face with a series of small holes openings 7 7, concentrically arranged at about the same distance from the center as the magnets 6. These holes are the inlets of a series of pipes 19 arranged raidally inside of the wheel and all communicating with a passage-in the shaft 2 of the wheel, as shown in Fig. 7, whereby with the aid of a suction pump applied to the end of the shaft, an QlI' SHCilOD can be constantly maintained through all of the The inlet to the chutes is located at a point slightly inside of the circle of magnets and the circle of suction openings 55 respectively, and the cams 1010, are. ar-

ranged to pass obliquely across the respective circular paths of the magnets and suction openings and terminate at the inlets to the chutes.

In the operation of the device the magnets will operate upon the metallic bottle caps while the suction openings will operate upon the cork disks. 1 wish to point out here however that the suction apparatus may be used on both sides of the wheel, and likewisethe magnets may be used on .both

sides of the wheel provided the articles to be acted upon are of such material as to be attracted by the magnets. The reservoir on the side where the magnets are exposed is I kept filled with the metal caps, While the reservoir on the other side is filled with the cork disks. As the wheel rotates in contact with the articles in each reservoir, the magnets and the suction openings in passing through the reservoir will pick up or attract to themselves the caps and disks, and as the wheel emerges from the reservoir it will carry with it at regular intervals a metal cap on one face and a cork disk on the other. In the cases of both the caps and the disks the position in which they maybecome attached to the face of the disk will be very irregular, since the cap or disk may be caught at one edge only and it may rest either to the right or to the left, above or below the pole of the magnetor the suction opening, depending upon the interference encountered in passing through the reservoir. This irregular positioning of the capsv is illustrated by the dotted lines 32 in Fig. 5. If the caps and disks were permitted to travel toward the mouth of the chutes in these irregular positions, but few of them would be properly presented to the chute and they would simply be carried back into the reservoir. Therefore in order to insure that each cap or disk which is icked up by the magnets or the suction, is elivered into the mouth of its respective chute, I have provided the cams or guides 10-10. These inclined plates as before stated, rest with their edges against the face of the wheel and being arranged obliquely to the path 0 movement of the magnets and suction openings, the caps anddisks are carried against the cams which cause them to slide or roll until they have been pushed or deflected radially inward on the face of the wheel to a position immediately in front of the mouths ofthe chute, the magnets or suction devices respectively continuing to exert their restraining or holding influence upon the caps or cork shivesduring this positioning operation and until forcibly disengaged therefrom. -This disengagement, in the case of the caps, occurs by reason of the magnets passing slightly behind the end of the. cam

10 and diagonally across the bottom of the chute channel at the mouth of the latter, so that they continue to exercise their attractive force upon the cap and draw it into the mouth of the chute the moment it leaves the cam and is presented in front of the chute, continuing to exert their holdinginfluence for a short distance after entry thereinto. With the cork shives the action is necessarily sli htly different; the positioning cam 10 sli es the shives, as they encounter it, Over. the face of the wheel without causing the disengagement of the shiv'es therefrom un" til the suction holes pass under the edge of substantially the extreme end of the cam,

, indicated in Fig. and marked A, A, .t

etc., while the relative positions of the suction holes are marked a, a, a, etc., and it will be observed by reference to Figs. 4 and j 10, that while the cam may be so positioned that the suction holes: pass diagonally be hind the end thereof, since one side and the bottom of the chute extend out beyond said end of the cam, the released shives will drop into said chute, and when fairly entered thereinto, will, by reason of the fact that the side of the chute adjacent the wheel is not extended'thereover, be further subject to the action of the suction device since the respective hole will again be covered by the shive or a succeeding hole will be so covered, depending on the speed of rotation of the wheel, and owing to the line of travel of such hole being diagonally disposed with respect to the bottom of the chute, will urge the shive farther down into the chute thus insuring space for the next shive to fall into. As soon as the cap or cork shive has been so drawn into the chute against and along the bottom thereof, the magnet or suction opening passes on and thecap or disk is free to roll down the chute to the assembling ma chine or other point where it is to be utilized. The cams 10 therefore serve to shift or alter the positions of the caps or disks so that they will all be uniformly brought directly to the mouth of the chute.

If the mechanism is used for feeding to an assembling machine, it is desirable to.

have the metal caps enter the chute with their flanges all faced in one direction. I To accomplish this and prevent any of them from entering the chute with their flanges facing in the wrong direction, the groove 15 in the bottom of the chute is provided. This groove begins at the very mouth of the chute and the distance from the bottom of the groove to the end of the cam 10 is just about equal to the diameter of the cap across its.

flange, so that the cap will be admitted to the chute if the flange enters the groove. On

the other hand, if the flange is faced in the opposite direction, the distance between the bottom of the chute and the end of the cam 10 is not so great as the diameter of the cap across the flange, and consequently the ca cannot enter the mouth of the chute, and, It

choke it. To relieve this condition I provide the slot 25 (Fig. 4) through which a pointed tool can be inserted to force the stalled disk out.
