Bv it known that I.

lii thvsv diawings. tho nunivriil 2 designates a siiitiihlv hopper which is rigidlyY si cured to a liasv plato 8. ThiS hopper prefvralily has downwardly curved convex inner walls servingr to prevent lpilingr up of the hlaiil` hviiig' agitated. The shell of this hopper has its lower portion 2 of larger internal and external diainvtvrs than the intermediate portion ot' thv hopper. this enlarged and otiset portion ot` thv hopper vavity forming a SeatY for an annular ratchet, ring Jr haring pvriplieral tvvth 5. The ring IY is dvsigiivd to hv given :1 Stvp-liy-stvp rotary iiiovvniviit, in an)v Snitalilv inaiinvr. In thv vonstriivtion shown. this n'iovvnivnt is vtievted hy nivans o'lA thv spring prvssvd pawl whivh iS pivotally nioniitvd at 7 upon a rvviprovatin ql pawl arrivr har 8. The bar H is iiioiintvd to rvviprovatv in siiitahln guides in thv liasv platv 3 and'liiis rigidly Secured ilii-rvlo an iipwardlitY extending post 9 in whivh is formi-d an oblique vain slot ltl (see "igiii'v 10). The slot is engaged by an anti- 't`rirlion rollvr l1 on thv vnd of an arm 1:2 whit-li in vonnvvtvd to soiiiv moving part of Athv iiiarliinv wliivh the tvvdvr Supplies. Siivh as thv i'vviprovating Cross hvad or div carrivr li. (Svv Figure l). As thv nieniher 13 is iiaipria-iitvd vvrtivally.l thv partS thus dv- -st-rihvcl will operatv to vii'vvt a Stvp-hystvp rotation of the ringr 4.
hvviirvil to thv ring lto rot-atv thvrvwith within thv lo .'vr portion of thv. hopper eiwit;Y arv two superimposed feeder inemlivrs if and '16. rl"hvsv inay bo connected to thv ring 4 in anyv Suitable mannvr aS by the lit-li' 1T indicated in Figure 5. The two parts arel otx annular forni, and arc provided on their pvril'ihvries alignvd vertical teedingchannelsy 18 through which the blanks may pass hvtwvvn said members, the lower pov tion of thv hoppvr cavity and the. inner wall of the ring 4. Tho twoinvmbeis l5 and 16 arv separated by a. cnt-0H" device 19 shown in Figiirvs 4 and 7, and which is rigidly keyed to a lions 3 on the hase plate 3. so as to romain stationary. This vut-off inenihvr is in thv foi-iii of an annular plate having a. segmental projection ma. This projection t9 ovvnpivs a. position directll over the diS- vhargv opening 20. Which lent s through tho has@ plat? 2 and communicates With the upper end of a delivery chute 21, the construction and arrangement of the passage 20 and the chute 21 being such that the metal blanks A can drop therethrough in edgewise position.
22 designates an agitating device within the hopper cavity and which is for the iurpose of preventing the metal blanks `troni packing too solidly in the hopper. This device is in the form of the frustrum of a cone and is mounted to revolve upon the pin 23 which is secured in the base plate 3. Its periphery is formed with a helical rib 2-1, the
i pitch of which is directed upwardiy to thereexert a constant lifting action upon the b sinks. The cone is rotated by a suitable connection with the feeder member 15, such as the dowel pin 25, shown in Figure 3.
26 designates a gate which is arranged to move into and ont of the upper portion of the chute 21 so as to alternately support `and release a blank failing through the chute. This gate is shown in blank-supporting posi tion in Figure 4. The gate is periodically actuated in proper timed relation by any suitable means. In the drawings I have shovgn the gate as being carried by a reciprocating bar 27 which is actuated by a lever 28 fulcrumed to the base plate 3 at 29 and hav` ing its opposite end provided with a post 30 which projects upwardly between the two followers 31 of the centraiizing springs 3Q, which are seated in the reciprocating pawl carrier 8. he lever 28 also has an upwardly projecting guide pin 33 which works in a guide slot 34, as best shown in Figure 2. It will be readily' seen that the gate 2G will by means of the connections just described, be reciprocated in proper timed relation to the movements of the machine being supplied by the feeder, the actuating movement being derived from the part 13 of such machine.
If, for any reason, it is desired to empty the hopper quickly, the member .27 may be pulled outwardly to withdraw the gate 26 from the chute and may be liiid in this position by a latch device 35, which can be swung into engagement with a notch 3G in said member 27.
The operation will be readily understood from the foregoing. The metal blanks A to be fed are placed in mass in the cavity of the hopper 2 where they are constantly subjected to the loosening action of the agitator 22. The blanks are gradually worked into edgewise position, passing down into the channels in the feed members 15 and 16, as shown in Figure 4, the lowermost blanks resting upon the upper surface of the base `plate until a lower blank is turned into registry with the upper end of the discharge passaee 20. At this time all of the blanks imme iately above the blank which is to be discharged into said channel are supported b the segment 19* of the separator or cutl-o device 19. Therefore, only one blank at a time can be discharged, such discharge occurring at each stepbystcp rotation of the parts. Each blank is heldin the shute 21 until it is released at the proper time by the withdrawal of the gate 2G.
-lily Vinvention provides a feeder of the character described which is simple in its construction and operation, there being a few movable parts and those being of a character such that they are not likely to get out of order. r1`he action of the feeder is there fore reliable and etlieient and can be depended upon to supply the blanks in regular succession and at the proper time intervals to the dies which shape the blanks. feeder is used in connection with machines for forming blanks for parts of collapsible tubes, the dies in question may be the cxtrusion dies which form the body of the tubes, or they may be the dies which shape the caps or closures for the tubes. As above stated, however, my invention is not limited to use in connection with machines of this particular character.
