21 Claims.

This invention relates to new and useful improvements in hopper feeds.

An object of the invention is to provide a hopper feed in which there is no tumbling action of the parts being fed whereby if they are finished as for example by being coated with lacquer, they will not become scratched or worn during the feeding operation.

An additional object is to provide a feed wherethey enter onto a disc and move from a position thereof of smaller diameter to a position of relatively larger diameter and are thus separated from one another.

Another object is to provide a hopper feed wherein articles are taken from a hopper and fed onto a disc on which they are directed to a raceway, means being provided for directing the surplus articles back to the mass at the lower end of the hopper.

A further object is to provide in an apparatus as indicated, means for rearranging articles not in correct position to enter the raceway so that when they are next fed to the raceway they are more apt to be in the right position to enter it.

Other objects and advantages will become apparent from a. consideration of the following detailed description taken in connection with the accompanying drawings wherein satisfactory embodiments of the invention are shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the. scope of the appended claims.

in the drawings: Fig. 1 is a top plan view showing the hopper feed constructed according to the present invention with a portion of the container broken away;

Fig. 2 is a vertical sectional view through the apparatus of Fig. 1;

Fig. 3 is an elevational view with parts away and showing the same apparatus; I

. Fig. 4 'is a top plan view showing a modified construction;

broken Fig. 5 is a. detail sectional view taken substantially along the line 5-5 of Fig. 4 and showing the action when the articles being fed are not correctly positioned to enter-the raceway; and

Fig. 6 is a view similar to Fig. 5 but illustrating the-passage of a correctly positioned article through a gauge means employed.

Referring in detail to the drawings, and at in as the articles are taken from the hopper first particularly to the form. of the invention shown in Figs. 1, 2 and 3, at 10 is generally indicated a substantially circular frame or support through which extends a driven shaft ll having an upperreduced threaded end portion 5 Ha; Within and of somewhat less diameter than the'support W is aplate or disc generally designated iii-By means of a key it or otherwise, disc i 2 is secured .to the shaft ii to turn therewith. An open ended hopper it is arranged above the disc 02 and includes a spider it having a hub portion it disposed over the upper end portion of a shaft H and clamped to such shaft as by means of a nut it threaded .onto. the shaft portion Ha. Shaft Iii is turnable in the frame it and it will therefore be clear that the disc I2 and hopper M are rotated together but relative to the frame.

Disc l2 includes an upwardly extending central thickened portion it entering the lower open end of the hopper it, and outwardly of such portion the disc is provided with the annular shoulder-J9 beyond which the disc has a. flat surface portion 26 bounded by an inclined surface portion 21! extending substantially to the outer edge or periphery 22 of the disc. Beyond the outer edge of the disc t2 the frame it includes a vertical wall portion 23 on the upper edge of which is disposed a ring like part 2 3 the upper surface 25 of which is above the upper surface of the edge portion 26 of the disc it while the inner edge portion 27 is spaced from the peripheral edge 22 of the disc thereby providing a raceway 28. Part 24 may be secured to member 10 by any suitable means and at its inner side includes an upper surface portion 29 flush with the surface portion 26 of the disc, and these surface portions together are to be engaged by the undersides of the heads 01. headed articles when the shanks of such articles are in the raceway it.

Hopper l4 receives the articles to be fed, and in Figs. 1, 2 and 3 such articles are disclosed as rivets 30, and particularly by reference to Fig. 2 it will be noted that the shoulder IQ of disc I2 holds back the mass of articles to be fed and prevents them from moving freely out of the lower end of the hopper onto the disc. As the disc and hopper revolve together there is no tumbling action of the articles while in the hopper and it will, therefore, be apparent that the apparatus may be used for the feeding of finished articles and that. during such feeding the surfaces of the articles will not be scratched or worn.

Disposed over the flat surface portion 20 and extending across the shoulder IQ of the disc i2 is a member or guide 3| supported as by an arm 32 secured to the part 24 by screws 33 or the like. Member 3| is stationary with respect to the disc l2, and since such member extends across the shoulder 19 it will be apparent that as the disc and hopper are rotated some of the articles 30 will be taken from the mass at the lower end of the hopper by the inner end portion 3|a of member 3| and fed or guided outwardly onto the disc l2 as clearly shown in Fig. 1.

Beyond the member 3| there are located sta tionary guide members 34 and 35 also disposed over the disc l2 and extending across the fiat surface portion 20 of such disc and up the inclined portion 2| thereof and terminating approximately at" the raceway 28. Members 34 and 35 are supported by arms 36 and 31 respectively and the outer ends of such arms are secured to the ring-like part 24 as by screws 38. The arrangement of member 34 is such that on the rivets 30 beingcarried beyond the outer end of member 3| they are carried over against the member 34, and as the disc continues to rotate the rivets are guided upwardly by the member 34 to the edge of the raceway 28. On reaching the raceway those rivets which are correctly positioned are received by it since their shanks enter the slot while their heads are supported by the

surface portions

26 and 29 of the disc and part 24 respectively.

The rivets which are not correctly positioned on leaving the upper or outer end 39 of the member 34 slide down the inclined portion 2| of the disc as at 30a and as they are carried along by the latter they are brought against the member 35 and are again guided upwardly toward the raceway 28. Those articles which are correctly positioned on leaving the upper end 40 of the member 35 enter the raceway if they are presented to an unoccupied portion of it, and the articles which do not enter the raceway, on leaving the outer end portion 49 of member 35 again slide down the inclined portion 2| of the disc toward the center or flat portion g: thereof. Several such articles are shown at Those articles 30b which do not enter the raceway after the second attempt on being carried along by the disc come into engagement with a stationary guide member 4| disposed over the disc and extending down the inclined portion 2| and across the flat portion 20, and hav- .ing an end portion 42 crossing the shoulder |9. It will, therefore, be apparent that the articles which are carried against the member 40 are guided by it back across the shoulder l9and into the mass-of articles being held back by such shoulder. Member 4| is stationary being supported by an arm 43 the outer end portion of which is secured to the ring-like part 24 in any suitable manner as by the screws 44.

The articles which enter the raceway are carried along as the disc I2 is revolved and are delivered to a chute 45 forming a continuation of raceway 28 which may be the feed chute to a machine which is to use the article or a discharge chute from the hopper feed. As shown, chute 45 is formed by bar-like members 46 and 4'! secured by screws 48 and spaced apart a distance to receive the shanks of the articles but to have the heads of such articles rest on their upper surfaces at their adjacent edges. Obviously, any other form of chute may be used raceway are not gripped and are with the hopper feed of the present invention. It will be understood that the alLticles in the herefore not positively carried along by the revolving disc I2 and that when the chute 45 is full the disc |2 may continue to revolve without binding the articles one against the other and that the apparatus will continue to feed articles up to the raceway 28 even though the latter be full so that additional articles may not enter it.

Figs. 4, 5 and 6 illustrate a slightly modified construction particularly adapted for feeding a somewhat different shape of article such, for example, as the snap fastener parts 49 each including a; head 59 flat on one side and on its other side provided with a short stud 5|. The structure shown for feeding these articles is for the most part the same as that of Figs. 1, 2 and 3 and includes the base or frame If], a disc |2a corresponding with the disc |2 except that disc |2a at its outer edge is provided with a horizontal portion 52 having a fiat upper surface 53 comprising a raceway. Also, the modified apparatus includes the hopper l4 mounted to be revolved with disc |2a as will be understood.

On the upper edge of the outer vertical wall portion 23 of frame IU of Figs. 4, 5 and 6 is a ring-like part 54 secured in any suitable manner and of a thickness somewhat greater than that of the edge portion 52 of disc |2a whereby such part 54 extends above the surface or raceway 53 providing a shoulder or stop 55 to prevent articles moving outwardly off the raceway. Particularly by reference to Figs. 5 and 6 it will be noted that the outer edge portion 52 of the disc |2a extends over the upper 'edge of the wall portion 23 of the base or frame and has its outer periphery relatively close to the inner edge of the part 54.

In the modified construction the articles 49 are taken from the lower end of the hopper I4 and guided outwardly across the disc |2a to the raceway 53 in the manner already described in connection with Fig. 1. It is desired that the articles be fed from the raceway all in the same position and disposed on the fiat sides of their heads 50 with their studs 5| directed upwardly. To insure that only correctly positioned articles will be carried along the raceway a gauge means 56 is secured to the part 54 as by screws 51 and includes an arm-like portion 58 extending across the raceway and provided in its under side with a groove 59 of a width to permit of the passage therethrough of the studs 5| of articles 49.

Gauge 56 is so located that correctly positioned articles on the raceway may be carried along under the gauge since the studs of such articles may pass through the groove 59 of the gauge. However, articles which are not correctly positioned will be carried against the curved front edge 60 of the gauge and forced off the raceway onto the inclined portion 2| of the disc down which they will slide. The articles which are rejected by the gauge are for the most part those which are disposed with their stud 50 downwardly and beyond the gauge there is provided a means for rearranging such articles or for turning them over so that they would be disposed on the flat sides of their heads after they pass the gauge, and will therefore be more apt to be properly arranged when next presented to the gauge.

The means for rearranging the article comprises an arm 6| secured to the ring-like part 54 as by screw 62 and having its portion 63 which the inclined portion 2| of the disc and then,

partway across its flat surface 2b.

This portion 64 of the arm is twisted into a somewhat spiral-like form so that in the length of the arm its lower edge passes from a position at the forward side of its upper edge as shown at the in Fig. 4 to a position at the rear side of such upper edge, as shown at Ebb. That is, the portion til of the arm is constructed somewhat like the mold board of a plow.

Therefore, as the articles at are carried against such .arm portion with their studs 5i lowermost their heads move over the lower portion of the arm as shown by the article tea in Fig. 4 and as the disc carries the articles along they are gradually carried up through and beyond a vertical position as in the case of the article Mb of Fig. 4 and fall over onto their From this it will be seen that by means of the arm iii articles which are rejected by the gauge 56 because of being incorrectly arranged will be rearranged by such arm ti and therefore are more likely to be properly arranged when next carried to the gauge.

From the foregoing it will be clear that with the means of the present invention the articles being fed are not tumbled upon one another in the hopper, and that owing to the shoulder or wall it the articles are prevented from moving freely out of the hopper onto the revolving disc at the underside of the hopper. Further, the arrangement is such that as the articles are taken from the hopper they enter onto a relatively wide disc and so are separated out or from one another. In each instance the articles which are presented to the raceway and do not ,enter it because of being improperly arranged are returned to the mass at the center of the disc to be again taken from such mass and ofiered to the raceway. Also, the articles are not fed positively along the raceway and thus if the latter becomes full there will be no wedging or binding action to interfere with the con- 'tinuous operation of the mechanism. It will also be seen that as the articles are fed out-' wardly from a surface of smaller diameter to one of larger diameter they are automatically separated or spaced from each other giving them a greater opportunity to rearrange themselves and not interfere with each other.
