To all whom it may concern.'

Be it known that we, EDGAR R. Iwnimn,

(iniciada F; JACKSON, and RALPH A.- G LnA soN, citizensof the' United States, and residents of Baltimore, Maryland, have invented certain new and useful Improvements m I Receptacle-Feeding Mechanism, of which the following is a specification.

This application in part comprises subject matter like that contained in an application led by us January 19,1917, #143,364.

Our invention concerns thev feedin of receptacles, such as can bodies or the l1 e to machines, which areto act thereupon, and.

one object vof the invention is to provide a feeding means which will engage the can bodies one after the other, 'and will move them with an accelerating speed from the station Wherethe en agement of the feeding means therewith'ta es place to a point of discharge, the can bodies being properly re` 'spaced at the point OfdiScharge, so that they may be acted upon by the machine in proper time.

l I Fi 4 is a vertical sectionalview of The invention lconsists in the4 features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings;

Figure 1 is a plan view of the feeding mechanism and this view also includes a portion of the machine to which the 'can bodies are fed.

Fig. 2 is a vertical sectional view'of Fig'. 1.V

Fig. 3 is a plan view ofa modification,

modi cation.

The apparatus includesa series of travelcan bodies of the series being fed. The 'arms' 1 are adapted to. swing 'about vertical ivots 2, which connect the said arms with t e rotating head or disk 3,A the pivots consisting of rods .4, suitably journaled in .the upper ange 5, and the lower bearing 6 of this head or disk and said arms carrying at their outer ends fingers 7, which are pivotall'y mounted ing arms 1, for engagingthe can bodies at a station A and delivering"V them at another lat the upper outer extremities of the arms 1,

as shown at 8, these -fingers being in the form. of weights depending Vfrom the ivots and having upwardly curved lower ges, as at on the rotary disk and they are propelled with the said disk Aby means of the fingers`9 engagin the can bodies and pushing them vin the irection of'the arrowc shown in Fig. 1. The can bodies may be delivered ontothe head or disk 3 in any suitable way but we prefer to employ an initial disk or feeding member 10, which receives the cans direct'froin a suitable exhaust box or conveyer. Guides 11 and 12, associated with the lnitial feed disk 10, serve to direct the cans, as indicated by the arrow b and as the initial disk 10 overlaps the head or disk 3 the can bodies moving in the direction of the arrow and directed by the guides will be delivered between the arms or fingers 9 to be prov '-ling fingers but should a propelling finger be in such a position' that a can body will strike or press upon thefouter edge or end of' the finger 9, this finger, being as stated in the form of a pivoted member, will yield and pass by this' paiticular can body and the next-oncoming finger will take this pari ticular can body.` and propel it onward, said;

- can body in this movement being under the control of the guide 12 and resting upon the rotating spacing disk 3.

- -As above indicated the movement 'of the can body. is accelerated or gradually increased from station A to mation B in the direction of thearrow. a, so: that in the case of filledcan bodies the movement imparted thereto byits propelling finger will beslow at first in order to avoid spillin the contents which would result from a su den impulse arms in effecting this discharfe. The can bodies therefore will be taken from a cond1-' tion practically at rest at the station a proxilnatelyat A Where they ma be crow and preferably these lugs extend downthrough slots 15 in the disk or head 3. The

spider is mounted to` turn Vabout -a post. 16 held in a boss 17 of a bracket 18 .forming part of the fixed frame. The spacing vd1s vor head 3 is mounted to turnabout a pin or post 16., extending up from the bracket arm 16 forming a lateral extension of the post 16, and from this construction it will be seen that'the spacing disk or head 3 and the spider are eccentrically arranged in relation to each other, their pivot or journal posts 16 and 16 being displaced in relation to each other out of axial alinement. The spider 13 is rotated b a worm wheel 19 from a worm 20 on a sha t 21, which is suitably journaled in the frame-work and is driven through any suitable means, such as the bevel gearingat 22. This same shaft 21 Ior an extension thereof drives the initial feed disk 10 by a worm gear, indica-ted at 23,

It will be observed that the eccentric relation of the spider and the head carryingthe propelling arms is such that at the receiving station approximating the' position A the stud 14 of the propelling arm. will engage the slot of the arm of the spider at a point close to the center of the rotation of the spider, as indicated on the right of Figs. 1 and 2, whereas at the discharge point approximating the position B the stud of the arm`which has reached this discharge sta* tion will be'engaged by the spider arm at the outer end thereof and of course at different angular positions of the rotating head between the stationsA and B, the studs 14 will be in engagement with the spider arms at points progressing from the inner to the outer ends of the slots.

Obviously when lthe studs 14 are engaging the spider arms near their center of rotation the movement of these arms with their propelling. fingers 9 will be slow,

.gressively increased, thus effecting the respacing or gradually increasing se aration of the can bodies and increasing t e speed of movement of said 'can bodies,l so that at 70 the point of .dischargethey will be respaced at proper distances apartto suit the movement or periods of movement of the parts of the machine which are to act thereon and if the can bodies are to be propelled-by a part of the main machine the speed ofthe can body when discharged from the respacf ing head and delivered to this moving part of the machine will .accord with the s eed of said part, so that there will be no su den .i

acceleration of speed and no sudden impulse imparted to the can body which would tend to spill the contents.

As an instance of means which may be associated with the feeding mechanism to receive the can bodies therefrom we show a continuouslyrotating rin 24 havingdogs 25 projecting above the p ate or frame 26, said. frame being slotted at 27 to receive'- this dog ring. The can bodies are delivered onto the main frame 26 of the main machine in front of the traveling' dogs 25,

' which engage the` can bodies and propel them onward between the ' guides 12 and 12 to stations at which suitable mechanism acts upon the can bodies.

The head 3 will be kept in rotation because ofthe movement imparted -thereto from the spider C by way of the arms 1, this transmission of power being continuously exercised.

We donot limit ourselves to the construction shown and as an illustration of the variations that might be employed within the scope of our invention. reference is made to Figs. 3 and 4. In these figures the propelling arms 1L are arranged to yield like the .o arms or fingers 9 when a can body is not properly engaged thereby, but presses upon the end ofthe arm. For, this purpose the arms are slotted at 28 to receive their pivotpins 41. The head '3a carrying this pivot point is arranged eccentricallyn relation to the spider 13a and instead of employing slotted arms, this spider carries supplemental arms 29 pivotally mountedat 30 to the are pivotally connected to the propelling larms 1a at points 31 intermediate of the length of said propelling arms. The supplemental arms have tail portions 29 connected by springs 32 vto the preceding sulpplemental arm y29 at the point 33 intermediate ofthe length thereof, and from this construction it will be seen that as the spider rotates it will pull around with it the propelling arms 1L through the medium of the supplemental arms 29. l

It will be observed that if a propelling arm strikes the can body end on or partly 13G end on insteadyof Aengagin the .can body with its lateral'face the sai propelling arm can yield radially'iinward -in respect to the head or disk 3", t 's being spring 32, which holds t permitted by the slotted construction at 28.-

The mounting of the rotary head and the spider is different in this modification from t at firstdescribed, involving a member 34 mounted in the .bracket 185,". said 'member havin a bearing at 35' for-the wormwheel 36, ich carries the hub 37 of the Spider and the rotary spacing head beingearried by a center pin 38 mounted in the member 34. The rotary spacing head is slotted rat 39 topermit connection tov be made between the supplemental varms 2 9'and the propelaturesrelatin to the 24r having dogs 25, andthe s otted tableare made the subject of another application. v
