1 indicates a seaming mechanism and 2 is the pedestal for the support of a container or body 3 to which a cover orend 4 is tobe united. The construction of the seaming mechanism may vary and it is unnecessary to describe its details asiit forms no part of the present invention. Sufilce it to say that it is provided with the usual seaming rollers that travel around and approach toward and recede from the work. So likewise there is mechanism for raising and lowering'the pedestal which, need not be elaborated upon here; 5 is a body conveyor consisting here of a sprocket chain having the usual fingers, 6 to-engage the bodies. The bodies travel over a support 7 in-which -the conveyor is located and associated with this supportare side. guides 8.

It-will be noted (Fig.5) that the seaming mechanism or pedestal 2 is located at the end ofthe I body conveyor and that the bodies are fed in a straight line to the point wherethey are ready to, be transferred to the pedestal. 9 indicates a cover stack for covers 4, and 10 is a marking device for the covers. 11 is a dial feed mech'ariism that serves to receive covers from the marking device and bodies from the conveyor and to bring them to the seaming mechanism. It will be notedthat the cover stack and the marking device are arranged in What may be called a concrete and preferred form in' tandem, and that the marking device is intermediate the cover stack and the dial feed mechanism, which latter is closely adjacent the seaming mechanism.; Also'it will be noted that the cover stack and the marking device are located at one side of the body conveyor butat a higher level than said conveyor. 12 indicates a cover separating'and feeding member mounted on arm 13 of rockshaft 14, and this memberhas a stepby-step movement on its working stroke, the first step separating a cover from thepile of covers and carrying it to the marking device and the second step transferring the marked cover from the marking device to the dial feed mechanism. It will be observedfrom this description of the operation and general arrangement of the machine that 'a very compact construction is obtained capable of' high speed.

The cover separating and feeding means are here constructed as follows: 15 is a rotating cam shaft carrying cam 16 with which latter engages cam roll '17 mounted upon member 18 that is free to oscillate upon rockshaft 14. Mounted. fast upon said rockshaft is a ratchet-like member 19 having shoulders 20 and 21, and carried by member 18 is a pawl 22 pivoted at 23 and normally urged into engagement with shoulder 20 by means of spring 24 carried by member 18.

Also-carried by member 18 is a block 25 seated in jaws 26 of 18 and adapted to engage shoulder 21 of member 19. 26 is a pawl releasingmember pivoted at 2'7 and adapted to be brought 'againstpawl 22 to cause it to disengage shoulder 20.. It will therefore be se'enth'at, when pawl 22 is in engagement with shoulder 20, the

oscillating movement in one direction of member 18, effected through cam roll' 17, will be transmitted-to member 19, shaft 14, arm 13 and cover separating and feeding memberl2; and

' that therefore a cover will be separated and fed by'said member, whereas when pawl 22is disengaged from shoulder 20, member 19 and the connections therefrom will'not be affected. If the movement of 18 in one direction has been transmitted. to 19, then the return movement of 18 will likewise be transmitted to" 19 by engagement of block 25' .with shoulder 21.

If pawl -22 is disengaged from shoulder 20 when 'member 18 is moved by cam 16 and cam roll 17 then member 19 will not be moved and consequently no cover will be fed from the cover stack. Pawl release member 26 is controlled by detector rod 28 which in turn is controlled by body detector 29' located in an opening in one arm 33 of rockshaft 31. Carried by rockshaft 31 is a third arm 34 to which detector rod 28 is connected, said rod 28 sliding in the framework. It will now be seen that spring 32 tends to move detector rod 28 against member 26 to thereby release pawl 22 .from engagement with shoulder 20 in opposition to the influence of spring 24. When, however, a body presses against detector 29 the effect of spring 32 is overcome and detector rod 28 moves away from member 26 so that spring 24 moves pawl 22 into engagement with shoulder 20. Thus, so long as bodies continue to be fed, the cover feeding mechanism is active to feed covers, whereas when no body is moving no cover is fed..

Marking device 10 (Fig. 6) consists of an anvil 35 and a hammer 36 between which cover 4 is placed by. feeding member 12. Hammer 36 may be operated-by any suitable means such as cam 37 on shaft 15 which actuates lever 38 pivoted at 39 and provided with teeth 40 that engage rack 41 on hammer 36. The hammer travels in guides 42. Cover 4, as it is propelled by member 12, travelsonsupporting le ges 43 in the framework, and as member 12 moves in acurvilinear path said ledges 43 are arranged to form a curvilinear-guide.

It will be noted that dial feed mechanism 11 is closely adjacent the marking device so that after thecover is marked it requires but a slight additional movement'orgsecond step to bring the marked cover from the marking device to the dial feed mechanism. The dial feed mechanism consists of a dial feed shaft; 44 which is given an intermittent quarterturn by any suitable means but preferably by those' disclosed in my application Ser. No. 582,752 filed Dec. 23, 1931, and carries wings, 45 to engage and'move the bodies from the conveyor to the pedestal and from thence to discharge chute 46 after the body and cover have been seamed together. The dial feed device further carries cover supporting segments 47 which together with'a guide 48 on the framework sustains the cover as it moves to the seaming mechanism. The cover, after it has been marked, is given a second movement by member 12 which bringsit into a cover supporting segment of the dial feed mechanism, after which it is carried to the seaming mechanism, a wing 45 meanwhile transferring a body from conveyor. 5 topedestal 2. Pedestal 2 then rises and seaming takes place after which the pedestal is lowered and the seamed body and cover is ejected by a wing as another cover and body are being brought into position to be seamed.

Attention is called to the fact that body conveyor 5 is a sprocket chain that passes over sprockets, one of which is shown at 50 and is driven from shaft 51 having a bevel gear 52 receiving motion from bevel gear 53 on cam shaft 15, and therefore advances a body at a definite speed by reason of engagement of finger 6 on the chain with a body which is thereby caused to move over support '7. One of the guides, here 8, extends over the pedestal. 2. Asa body approaches the end of support 7; a wing 45 on the dial engages said body and transfers it from support 7 to pedestal 2, said body slidingvagainst guide 8. This causes said body to be moved, first with an accelerating motion so that it moves faster than finger 6 on conveyor 5 and then with a decelerating motion to bring it to a state of rest on the pedestal. It willalso be seenthat this movementof the body is in a straightline rotatable member having a wing to move a body in a straight line directly from the body conveyor to the pedestal first with an accelerating motion to cause the body to move faster than the body conveyor and then with a decelerating motion to gradually bring the body to rest on the pedestal, and having a cover supporting segment to move a cover in a curved path to the seaming mechanism so as to be seamed to said body.

2. In a machine of the character set forth, a pedestal to receive a can body; a seaming mechanism associated therewith; a body conveyor extending up to the pedestal; straight guides extending above the body conveyor, at least one of said guides extending over the pedestal; a rotat- .able member having a wing to move a body in a straight line directly from the body conveyor to the pedestal first with an accelerating motion to cause'the body to move faster than the body conveyor and then with a decelerating motion to gradually bring the body to rest on the pedestal, and having a cover supporting segment to move a cover in a curved path to the seaming mechanism so as to be seamed to said body; and means to feed acover to said cover supporting segment.

3. In a machine of the character set forth, a pedestal to receive a can body; a seaming mechanism associated therewith; a body conveyor extending up to the pedestal; an intermittently rotatable member having a wing that passes over said conveyor and pedestal to thereby move a body from the conveyor to the pedestal at a single step, and having a cover supporting segment adjacent the wing; and means to feed a cover to said segment before the wing transfers the body from the conveyor to the pedestal.

4. In a machine of the character set forth, a pedestal to receive a can body; a seaming mechanism associated therewith; a body conveyor ex- .tending in a straight line up to the pedestal; an
