CAN FEEDING MECHANISM Filed Jan. 20, 1928 2 Sheets-Sheet l 39. Thus a passage is provided from the delivery chute between the fixed guides 33 and 35, which are spaced slightly more apart at the receiving end to permit engagement ,ofvv the scans ;by the f d n t n fl 2: I

In the central portion 18 of the receiving disc are a number of downwardly extending bosses in which studs 41 are rotatable. The lower end of each stud is formed with sin let-42 andextends slightly below the bossAD toproyide a, space for seating a coil spr'in'EllBQ wh m extends around the stud with one en'd'eitending into'th'e slot 42 and held in place by a cotter pin 44, and the other end extending ifitoa recess 45 atfthelower end of the boss 40.

At the upper'end of each stud a can feeding fin er 46*is, s cured hav n acute-out 11866551515 directly above the-stud 41 and having. an opposite:

be noted that just before the-cans are delivered to the transfer discat thele ft'of thisflgure, the

fin ers 46am spaced more' widely apart than at any' o ther point 'lhis is caused bytheslraperof the cam groove 53, it being bulged outWQlfdlyrfrom thdPQSblO so that the'extension49 of each deed-1 finger, 46 vis moved quickly inean outward direction, causing.;a corresponding forwardmove mentor the can-engaging portion of-the finger, thereby accelerating themovement of' each canin the samcdirectiqnpf movement asthat of-the feeding disc, accelerating the can body just-before and asl it is deliveredhom the ieedingandtiming mechanism. I Q

In order to accurately adj ust the position' 'of' the cam member.52,- it is provided with-two spaced A lugs 55extending.upwardlyfrom the:top there-;

With this construction the cans are received at'a relatively low speed, unspaced, and untimed; they are advanced, spaced apart, and timed; and they are accelerated witha predetermined action calculated to prevent sp lling of the contents, to the speed of the transfer turret to which they .are delivered.

'It is thought that this invention and many of 'itstattendantadvantages will be understood from ,the foregoing description, and it will be apparent ljthatlrflany fchanges may be made in the form,

" construction andjarrangement of the parts without departing from the spirit and scope of the invent-ionizer sacrificing all of its material advantages, the form hereinbefore described being merely a' preferred embodiment thereof.
