This invention relates to improvements in feeding mechanisms, and more particularly to amechanisn for properly seating articles and for ejecting improperly seate 6 articles. j

An object of this invention is to provide an improved feeding mechanism for properly seating therein 'articles such as "top heavy screws and the like.

10 Another object of this invention is to an improperly seated article without 'ficting the adjacent properly seated arti- Other objects and advantages will more fully appear from the following detailed description taken in connection with the accompanying drawings which illustrate one embodiment thereof.

Inthedrawings,

Fig. 1 is a fra entary plan view of a mechanism embo ying the features of the icililyention applied to a screw slotting ma- Fi 2 is a fragmentary front elevation of Fig. 1;

Fig. 3 is an enlarged detail view of'the slide-way, and

Fig.4 is a front view artly in section of the structure shown in ig. 3.

Referrin -now to the in which h e reference numerals designate similar parts throughout the several views, 10 denotes generally a frame to which is 5 suitably secured a hopper 11 and an associated slide-way 12. Located in the hopper 12 is. a lift 13 which is adapted to be reciprocated in an arcuate path by'a system of levers 14 operated by any suitable means (not shown). The upper end of the lift 13 is provided with a groove 15 for picking up headed blanks 16 in the hopper 11, and in operation when the lift 13 is at thepeak of its upward stroke the groove 15 is in alignment with a groove 17 in the slide-way 12.

Positioned immediately over the upper extremit of the groove 17 of the slideway 12 an over a part of the groove 15, when the lift 13 is at the end of its upward stroke,

is an endless belt 18 having an outer surface of bristles 19 suitably secured thereto, the bristles 19 bein in engagement with the heads of the heade blanks 16. The belt 18 is carried by two pulleys 20 and 21 and is ro-' vide in a feeding mechanism means for ej ectdriven in the direction "maimed by the m e row by a pulley 50, operated by any suitable means (not shown), both the pulleys 50 and 20 being splined to a shaft 22 which is rotatabl supported by two

brackets

23 and 24 which are secured res ctively to the sides of the slide-way 12. 15 1: pulle 21 is keyed to a shaft 25 which is rotatab y suported inopposite sides of the hopper 11 y bearin 26 and 27.

Secure to the shaft 22 adjacent the bracket 24 is a bevel gear 28 which meshes with and drives a similar bevel gear 29 secured to a shaft 30 rotatably supported by

brackets

31 and 32,'which are suitably secured to the sides of the slide-way 12. Positioned between the

brackets

31 and 32 and secured to the shaft 30 is an ejector or kick-out Wheel 33 of usual construction, which is adapted to rotate at right angles to the groove 17 in the slide-wa 12. The teeth [6 of the kick-out wheel 33 c ear the heads of the blanks 16 which are pro erly seated but eject all impro rl seated lanks 16. Located to one .si e o the wheel 33 and on the frame 10 is a receptacle 34 for receiving the ejected blanks 16. w

Positioned adjacent the lower extremity of the slide-way 12 is a clam ing or indexing disk 35, rotatablymounte on the frame drawings in detail' 10, which may be operated by any suitable means (not shown). This disk 35 is adapted to take up the hea ed blanks 16 as they leave the groove 17 in the slide-way 12 and to carry them under a slotting saw 36 which may also be operated by any suitable means not shown). The sides of that portion of t e groove 17 under the belt 18 are provided with a plurality of interference points 37 (Figs. 3 and 4) each having a shoulder 38 and a pluralitiyl' of clearance points 39 which cooperate wit the bristles 19 in properly seating the headed blanks 16. It will be noted that'the width of the groove 17 may be varied in order for it to accommodate various size articles to be fed.

The operation of the mechanism is as follows: 4

The blanks 16 within the hopper 11 are picked up in the groove 15 of the lift 13 and when the lift 13 reachesthe peak of its upward stroke, the groove 15 being then in alignment with the cove 17, the headed blanks 16 are brush into the groove 17 of previously ex lained.

The heade blanks 16 as they are propelled or brushed along in the groove 17 by i the belt 18 assume various positions as denoted by reference characters and 11 (Figs. 3 and 4). k

The blank 16 in position 40 is shown lying on its side with its head djacent one of the sides of the groove 17 and not in'its correct position in the groove. The bristles 1,9 of the belt 18 move the said blank 16 along from position 40 to position 42 in which the head of the said blank is in contact with the shoulder 38 of the interference point 37. It

will be noted that the shank of the blank 16 shown in position 42 extends into the space provided by the clearance point 39. The bristles 19 come into contact with-the head of the blank. 16 in position 42, and through the medium of the clearance point 39, which allows the blank 16 to escape from the point of interference, turn the blank 16 over into its correct position 43. I

The blank 16 in position 41 is shown'lying on its side in an opposite position to the blank 16 shown at position 40. This blank 16 in being propelled along the groove 17 assumes a position similar to that assumed by the blank 16 shown in position 42, and then by the bristles 19 is in like manner caused to turn over into its proper position 46. 7

As more fully described previously the shaft 22, carrying the pulleys and 20 also drives, through

bevel gears

28 and 29, the kick-out wheel 53. Should any'of the blanks 16 be jammed or improperly seated after they pass from under the bristles 19 they are ejected by the kick-out wheel or ejector 33:

and. fall into the receptacle 31 from which they may be removed from time to time and placed into the hopper 11.

The blanks 16 are constantly being propelled downward in the groove 17 of the slide-way 12 by' the bristles 19 and upon their reaching the lower extremity of the slide-way 12, they are carried around by the disk 35 under the saw 36 which slots their heads, and are then ejected into any suitable receptacle (not shown).

It is readily apparent from the above description that not only are the blanks 16 propelled forward much faster, but that the 'seaglng of the blanks 16 is greatly accelerate Furthermore, byarranging the kick-out wheel or ejector 33 at right angles to the groove 17in the slide-way 12 only the improperly steated blanks are ejected thereby increasing the efiiciency of the feeding mechanism.
