.GEORGE COOPER, OF'SOUTH LEBANON, OHIO, ASSIGNOR 0F ONE-FOURTH T0 LOUIS LUEDEKE, OF HOPKINSVILL'E, OHIO, AND ONE-F OURTH TO JESIAH ELLIS CLARK,

OF SOUTH LEBANON, OHIO.'

Be it known-that I, Gnonon Coorcn, a citizen of the United States, residing at South Lebanon, in the county, of \Varren and State of Ohio,ha\'e invented new and useful Improvements in Can Cap- Feeding Machines, of which the following is a specification.

This invention relates to a machine ofthat. type which automatically drops caps upon cans fedsuccessively through the ma} chine. r

The invention has for one of Its ob ects to improve and simplify the'construction and operation of machines of this character so as to be comparatively simple and nexpen sive to manufacture, reliable andefiicientin use, and composed of comparatively few parts.

fective operating means for the jaws that control the feed of the caps from the magazine or cap holder. I

With these objects in view and others, as will appear as the description proceeds, the invention.comprises the various novel features'of construction and arrangement of parts, 'whichwill he more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanyingdrawin s, which illustrate one embodiment of the invention, Figure l'is a side view of the. machii'ie. Fig. 2 is a plan View thereof; ,Fig. 3 is -a transverse section on line 3-4), Fig. Fig. at is a'longitlulinal section on line .l, Fig. 2-, showing. the lowermost cap separated from the pile in the magazine .tube and just prior to being dropped on the can. F 5 is a similar section showing the parts in the opsupporting plate with the jaws and slide.

Specification of Letters Patent. Patented F61). 21, 1911. Application filed June 11, 1am. Serial No. 566,360.

and ll'are diagrammatic views showing different positions of the jaws in the process of dropping a cap. Figs. 12 to H are .plan

views of the jaws and ejector, the figures.

corresponding, respectively to Figs. 9, 10 and 11. y I Similar reference characters are employed to designate corresponding parts throughendless conveyer or belt 1 that has spaced can-engaging lugs 2 whereby the cans are carried forwardly with the belt. Mounted in cooperative relation with the track is the can-dropping mechanism that is operated automatically. by the cans, so that each time a can passes, a 'cap will be deposited thereon. Secured to the track A is a bracket 3 in which is fastened the lower end of a standard. or post which forms a part of the frame of the'machine. Fastened to the upper end of this, standard or post is a horizontal plate 5-which overhangs the track A,- so that the cans will pass under the plate, the said-plate having secured thereto a ring 6 through which the standard 1 extends, and in this ring is a set screw 7 which binds on the standard or post so that the plate can be secured in any vertical position of adjustment. Disposed between the hearing or bracket 3 and plate 5 is a. star wheel 8 that is so arranged that its-arms will extend partly over the track to be engaged by the cans. and rotated thereby as they are fed through the machine by the belt 1. Secured 'to this star wheel is a gear wheel 9 thatmcshes with a pinion 10 fastened ona vertical shaft 11 which is journaled ina bracket 12 fastened to and extending forwardly from the plate 5. On the upper end of this shaft 11 is a. crank 13 which serves to operate;the capfeeding mechanism.

- The caps to be fed are held in an inclined the'lower parts 0 the magazine tube willhe supported-one onanother in avertical yertical line.

are secured by bolts 16 to cross bars 17 that'- line, while in the upper portion of the magazine they are disposed at an angle to the The two sections 14 and or opening 21 that coincides with the opening 20 of the slide so as to permit caps to pass through the plate to the cans moving thereunder. The rear end of the opening 21 in the plate 5 terminates in front of the axis of the. vertical ortion of the magazine, so that'when the ide or ejector is completely retracted, the cap about to' be dropped will rest on the plate 5 that fdrms a seat for the cap. When the capis thus seated on the plate 5', it will be in the same plane with the slide or ejector 19, and as the latter advances or moves to the front, the cap will be engaged by the inner end of the recess 20 and caused to move with the-ejector until it drops out of the recess 21 in the plate 5, or cap seat. This slideor ejector 19 is connected at 22 with a lever 23 which has one end fill-- crume d at 2 1on the plate 5 at a point behind the standard 4., and this lever has its intermediate portion connected at 25 with the rear end of a pitinan 26 that is connected with the crank 13. The gearingbetwcen the star wheel and cr'ank shaft is so proportioned that the crank will make one revolution every time a can feeds through the machine, and consequently the slide or ejector 19 will move forwardly and rearwardly to eject the caps successively in timed relation to the cans.

To control the feed of the caps from the magazine to the ejector, a pair of bar-like jaws 27 are arranged between the lower end of the magazine and the ejector. These aws are spaced apart and disposed at opposite sides of the axis of the magazine or pile of caps and have their forward ends pivotally connected by screws 28 to the slide or ejector 19 at oppositesides of the opening 20 therein, and thesejaws extend rearwardly on the slide and are connected together by a helical extension s rin 29. The ends of the s rin p b D are connected to upstanding posts or lugs 30 on the rear ends of the jaws so as to draw the latter together. The jaws move back and forth with the slide and freely pass under the bars 17 that support the two sections of the magazine and on the bar that carries the rear or main section of the magazine is an abutment formed of beveled surfaces 31 which aredisposc'd in the path of the lu'gs 30 on the rear ends of the jaws, so

the ejector moves forwardly to drop a cap,

the lugs will strike the. abutment and cause' the jaws to move open so that the next succeeding cap can drop upon the'top surface of the slide or ejector 19. In order to reduce the wearbetween the lugs 30 and abutment surfaces 31, the lugs are provided with sleeves or rollers 32that freely turn, and it will be noted that the spring 29' is supported high enough so as to pass over the abutment with which the roller-s engage. Each jaw has its inner edge beveled upwardly from the bottom to form a knife edge 33 which extends from the front extremity of the jaw to an intermediate point 3d, and from the point 3 to'the rearend of the jaw, the inner edge thereof has a downwardlysloping bevel 35. To limit the closing movement of the jaws, the slide or ejector 19 is provided with stops 3G with which the jaws engage. Mounted on the front cross bar 17 is a guide or deflector 37 in the form of a bent spring which insures the dropping of the-caps if they should tend to stick in the machine.

The operation of the machine will now be briefly described, and assuming that the magazine is filled with caps and that the cans are feeding through the machine, the cans will turn the star wheel continuously and as the result the caps will drop one at a time on the successive cans. During the forward movement of the slide or ejector, the cap which has been dropped into the opening 20 of the ejector will be ejected and at the same time the jaws will be opened so that the next cap can pass bet-ween them and drop on the top of the ejector, the edge of the cap sliding down the beveled surfaces 35 of the jaws. During the return stroke, the jaws will close and the knife edges 33 thereof will pass between the lowermost cap resting on the slide and the next'cap, and by this act-ion, the column of caps in the maga zine will be supported; Finally, the lowermost cap, which has been separated, will drop upon the plate 5 as the slide or ejector recedes, since the rear section ofthe magazine will prevent the said cap from receding with the ejector. The ejector now reverses its movement and causesthe separated cap to drop through the opening 21 of the plate 5, and while this occurs, the knife edges 33 pass from under the lowermost cap in the magazine so that the whole column can move one step downwardly by the lowermost cap dropping between the open jaws. These operations are repeated continuously as long as the machine is in use.

'From the foregoing descript'on, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have that as described the principle of operation of the liit invention, together with the. apparatus which I now consider' to be-{th'e' best embodiclaims appendedhereto.
