Bridgeport, Conn., assignor to Clark Metal Products, Inc., Bridgeport,. 1 Conn, a corporation of Connecticut Application May 21, 1934, Serial No. 726,761 Claims. (01. 193- 43 engages the slot H either forwardly or rear- The present inventionrelates to an apparatus for arranging and feeding irregular shaped articles, particularly articles which are not fiat, as for instance the formed up plug and binding 5 post member of an electrical plug device, an object being to provide such an apparatus into which a large quantity of the articles may be placed and which will then arrange and feed them in a predetermined position, this position being, for instance, one in which the articles may be fed into a dial type machine for the purpose of a forming or assembling operation on the articles, as for instance the attachment thereto of a binding post screw. To this end it is particularly proposed to provide a machine having a slideway to which the articles are fed promiscuously, that is with either end foremost, a second slide-way .in which they are fed in pre-arranged uniform position, and means between the two slide-ways for automatically feeding them in said pre-arr'anged position irrespective of the position in which they emerge from the first'slide-way.

With the above and other objects in view an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be'hereinafter more fully described with reference thereto and the invention will be finally pointed out in the claims.

In the drawings:

Fig. 9 is a similar view, and showing the manher of feeding the articles when in another position. Similar reference characters indicate corresponding parts throughout the several figures of the drawings. a

Referring to the drawings, the apparatus according tothe exemplary illustrated embodiment of myinvention, comprises an inclined slide-way l0 having a centrally disposed slot I l' therein, the upper end of the slide being engaged in the outlet opening of a hopper I2 which feeds the articles to the slide in either of the two positions indicated in dotted lines in Fig. 3, that is, with the prong or plug portion A of the article which wardly. The baseof the article B engages flatly on the top of the slide. and the articles move downwardly by gravity. The hopper may be of any suitable type, and if desired may be dispensed with and the articles placed inthe slide ID by hand. The lower end of the slide ID is engaged in a block member l3 having a cut-out I4 to receive it, being secured thereto by screws l5, engaged in the upstanding portions "5 and ll of the block at each side of the cut-out I l. The block has a passage I8 therein extending at right angles to the slot H and into which the articles move from the slide-way I0, the width of the passage being slightlywider than the width of the plug. portion A ofthe article so that it can receive it crosswisetherein, as seen in Fig. 3.

v The passage is preferably formed by a block member 19 of 'L-shape in cross-section secured to the base of the block member I3, as clearly shown in Fig. 6.-

A cover bar 20 is mounted on the slide-way I0, being provided with threaded studs 2l-2l projecting at one side which are engaged in slots 22-22 of brackets 23-23 secured to one side of the slide-way and adjustably secured therein by nuts 24-24. This bar 20 provides with the top of the slide-way III a horizontal slot for the bases B of the articles. a

At one side of the block member l3 an arouate slide member 25 is secured by screws26 and is provided with a T-slot 21, the rearward wall of the upright portion of this slot being flush with the rearward wall of the passage l3. An inclined slide-member 28 is secured by screws 29 to the lower end of the arcuate slide member 25 and has a T-slot 30 in continuation of the slot 21 and which is adapted to convey the articles to the dial press 3| (Fig. 1) or other machine into which the articles are to be fed. A pair of cover strips 32-and 33 are secured to the slide members 25 and 28 to retain the articles in the T-slot, the

inner edges of these strips being spaced apart to provide a slot through which the articles may be observed and engagedby a suitable tool in the event of jamming. i

A painof cam members 34 and 35 are secured upon the top surfaces of the respectiveblock members 13 and I9 at each side of the passage l3 and at the right of the slide-way In, the inner surfaces of these cam members being flush with the sides of the horizontal portion of the T-slot 21. The ends of the cover strips 32 and 33 extend over these cam members, the end ofthe strip 32 terminating adjacent the side of the cover bar 20, and the end of the cover strip 33 extending infront of the end of the cover bar. A feeding slide is provided at the end of the passage l8 opposed to the slide member 25, andcomprises a slide-way block 36 secured to the s PATENT OFFICE a means and is adapted to retract the plunger in' one direction of movement and permit it to project under the action of the spring 4! in the other direction of movement, projection of the plunger causing the articles to be fed along-'thepassage lfl, as will presently more fully appear.

An angular guide spring 42 is'secured'in the" forward wall of the passage l3, its inclinedpon,

tion extending inwardly from said wall and its end portion being flush with the forward wall of the vertical portion of the T-slot 21. v

The operation is as follows:--

The articles move by gravity along the slide- Way I8 and may be disposed therein in either one of two positions, that is with plug portion A either disposed forwardly'or rearwardly. Considering firstthe case of the article withthe plug portion forwardly, as shown in Fig. 8, where this article has moved from the end of the slot H into the passage 48, the rearwardly extending portion of the baseB is engaged upon thehorizontal surface above the passage 58, as seen in Fig 8. As the feeding plunger moves in the passage i8 the article is fed to the right and the end of the base portion B engages the cam member 34, so that the article is tilted as shown in dotted lines, and the plugportion is disposed forwardly as it slidesalong the guide spring 42- into the T-slot 2?. In the case of the article being in the slot l I with the plug portion rearwardly, as shown in Fig. 9, the forwardly extending portion of the base B Will'enga'ge'the horizontal surface below the pas-- sage 18, as seen in'Fig. 9. As the plunger is projec'ted' to feed the article the latter will engage the cam member 455 and be tilted, as shown in dotted lines, to dispose the plug portion A forwardly in the passage. It will be seen that in either case the articles 'all will be fed in the T-slot 21' of the slide-member 25 in the same position, irrespective of their position in the slide Iii.
