L. ONDERDQNK ET AL FEEDING MECHANISM FOR CUP FEED MACHINES Filed Dec. l4, 1921 4Sheets-Sheet 4 W W M oscillated, and as said plate is oscillated it will intermittently turn the shaft 7 in a clockwise direction, as viewed in Fig. 3. Said clutch actuating plate 10 is vibrated by means of a link which is connected to a ball stud 16 carried by the clutch plate, and to a ball stud 17 adjustably mounted in a slot 18 formed in an arm 19. The arm 19 is fixed to the lower end of a shaft 20. This shaft 20 is mounted in

bearings

21 and 22 carried by the casing 1. The shaft 20 is adapted to be oscillated, and as said shaft oscillates it will impart vibrations to the clutch plate 10, and this in turn will rotate the shaft 7 intermittently or step by step.

The feed wheel 6 is mounted torotate in a bracket 23 which is pivotally mounted at 24:

so that said feed wheel may be bodily swung away from the inner feed wheel 5 to permit the insertion of the material. Said bracket 23 is normally swung so as to hold the feed wheels yieldingly in contact with each other by means of a spring 25, and said bracket may be swung in the opposite direction by a means of a lever 28 which is connected to a knee shift or treadle.

The feed-wheel 6 is connected by a suitable series of gears to a gear wheel 29, shown in dotted lines in Fig. 1, and this gear wheel 29 is carried by avertical shaft 30, also shown in dotted lines in said figure. On the upper end of the shaft 30 there is a clutch mechanism similar to that-shown more in detail in Fig. 3. Said clutch mechanism includes a clutch actuating plate 31, clutch dogs 32, shown in dotted lines in Fig. 2, and a clutch disk connected to the shaft 30 upon which said dogs are adapted to grip for intermittently turning the shaft 30. Clutch actuating plate 31 carries a ball stud 33, to which one end of a link 34 is connected. The other end of this link 34 is connected to a ball stud 35 which is adjustably mounted in aslot 36 formed in an arm 37 which is connected to the upper end of the shaft 20. As the shaft 20 oscillates, it will move the link 34 back and forth and impart intermittent or step by step movement to the outer feed wheel 6. 1

By adjusting the position of the ball stud 35 in the slot 36, the length of the'feed move ment imparted to the outer feed wheel may be varied. Likewise by adjusting the stud 17 in the slot 18 in the arm 19, the feed stroke of the inner feed wheel maybe varied, and while both these feed wheels are intermittently operated from-the same shaft 20, these devices afford means whereby the feed stroke of either feed wheel may be varied relative to the other so that saidfeed wheels may be caused to move to feed the material in unison or one feed wheel feed or crowd the material a little faster than the other to suit whatever class of work is being done.

The shaft 20 is provid wi h n a m 7'.-

This arm 37' carries a ball stud 38 with which a link 39 is connected. The stud 38 is mounted for adjustment in a slot 40 formed in said arm 37, and indicated in dotted lines in Fig. 3. The link 39 at its other end is connected to a ball stud 41 carried by a lever 42 which is pivoted to swing about a fulcrum center 43. The inner end of the lever 42 carries a ball stud 4:4, to which an eccentric strap 45, cooperating with an eccentrio 16 on the main shaft 2, is connected.

It will readily be seen that by adjusting the ball stud 38 the extent of oscillation imparted to the shaft 20 may be varied, and this will simultaneously vary the feed strokes of both the inner and outer feed wheels. It will be apparent, therefore, that we have provided a feeding mechanism for a cup feed machine wherein the feed stroke of the inner and outer feed wheels maybe independently adjusted and wherein the feed stroke of the inner and outerfeed wheels may likewise be simultaneously adjusted.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.
