FEEDING DEVICE FOR VIAL MACHINES.

, Original application filed November 15, 1918, Serial No. 338,179. Divided and this application filed.

January 26, 1921.

To all whom it may concern:

Be it known that BENJAMIN T. HEADLEY, PARKE H. THOMPSON, deceased (whose executrix is RENA M. THOMPSON), and DAvn) IRVIN DU Bors, all citizens of the United States, residing at Millville, in the county of Cumberland and State of New Jersey, have invented a new and useful Improve ment in Feeding Devices for Vial Machines, of which the following is a full, clear, and exact description.

The present invention relates broadly to feed devices for vial-working machines, and more particularly to a hopper feed for vialbottoming machines.

An important object of the present invention is to provide a form of feed device adapted to contain a plurality of vial blanks for delivery to a vial-bottoming or other machine, and adapted to feed the blanks as required. a

Another object of the present invention is to provide a hopper feed device adapted to receive vial blanks directly from a necking machine and retain the same in position to be fed to a bottoming machine as required.

Still another object of the invention is to provide an adjustable hopper adapted to receive and hold a plurality of vial blanks.

A further object of the invention is to provide a hopperfeed device having means for gradually feeding the blanks in timed relation to the operation of the machine to which they are fed.

A still further object of the invention is to provide a hopper feed device having a discharge chute with means for controlling the passage of blanks thereto.

An additional object of the invention is to provide a discharge chute of the characterdescribed which is adjustable to accommodate blanks of difierent lengths, and which co-operate with a guard insuring proper delivery of the blanks to the vial working machine.

The foregoing and other objects of the present invention, together with their attendant advantages, will be apparent as the invention becomes better understood by reference to the accompanying specification Serial No. 440,115.

and drawings forming a part thereof, it being premised that changes may be made in the various details and manner of operation within the scope of the appended claims without departing from the spirit of the invention.

In the drawings:

Figure 2 is a transverse sectional view on the line II+'II of Figure 3;

Figure 3 is a side view of one end of a vial bottoming machine having the hopper applied thereto;

Figure 4 is a longitudinal sectional view of the mechanism disclosed in Figure 3, and also illustrating a portion of a vial necking machine;

' Figure 6 isa view corresponding to Figure 5 of a straight blank for wide mouthed bottles.

.wheels 3 over each of which passes an endless carrier 4. The endless carriers and sprocket wheels 3 lie in the same horizontal plane and therefore only one of each appears in the drawings. These carriers are preferably flexible, and may comprise link belts or chains, having secured to certain of the links thereof blank carriers 5 of any desired construction adapted to receive the vial blanks B.' It will be understood that in machines of this nature, the endless carriers are moved to successively bring the different blank supports withtheir blanks thereon first to 'a plurality of heating stations and thereafter to separating and bottoming stations as is customary in the art.

As the construction of the vial working machine constitutes no essential feature of the present invention, it is not illustrated in detail, but may bebuilt in accordance with the disclosure of our co-pending application, Serial No. 338,179, filed November 15, 1919, of which this is a division. The present application involves more particularly the feeding of the vial blanks to the blank supports on the endless carrier, and this mechanism will now be described in detail.

This feed mechanism preferably corn prises a hopper having an inclined bottom '6, with one fixed side 7 and an adjustable side 8. Any desired means, such as brackets 9, having suitably slotted openings formed therein, may be provided "for accomplishing this adjustment to accommodate the hopper to vial blanks B of different lengths.

l t will be anparent that the blanks may be manually p aced in the hopper, although it is preferably constructed of such length that the open receiving end thereof may co-ope-rate directly with the ejection opening 10 of a vial necking machine 11, asshown in Figure 4. The delivery end 01"? the hopper extends over the receiving end of the bottoming machine, and may be supported on any suitable bracket 12 carried by the frame 1 of the machine.

Below the bottom 6 of the hop-per are a series of bars 13 and 14, which bars are provided with upwardly extending lingers 15 projecting through openings 16 in the bottom of the hopper. The bars 13 have a connection 17 with one end of each of the T or walking levers 18, while the bars 14 have a similar connection 19 with the opposite ends of the levers 18. Both of these levers have pivotal supports 20 and are formed with downwardly extending arms 2i connected by a link 22 which insures the walk- .ing levers moving in unison. For oscillating the levers to produce the desired feeding movement of the fingers 15. one of the pivots 20 may be provided with crank arm 23 having a pivotal connection with a link 24, carried by a lever 25 pivotally supported at 26 on a bracket 27 secured to the main frame 1 of the bottoming machine. The forwardly projecting end of the lever 25 carries a roller 28 adapted to cooperate with a ram 29 on a longitudinally extend i-ng shaft 30 of the bottoming machine. lhis shaft may be rotated in any desired manner, not shown, for operating the lever 25.

Extending rearwardly from. the bracket 2-? is a seat 31 having a projection 32 thereon, adapted to receive a compression spring 33, the opposite end of which surrounds a similar projection 34 on the lever 25. It will ,now be apparent that the cam 29 periodically operates the lever 25,' through the mechanism described, against the action of the compression spring 33 to lower the bars 14; and raise the bars 13. As soon as the high point on the cam passes from engagenent with the roller 28, the compression spring will function to raise the bars 1% and lowerthe bars 13 to their original positions. ilach operation of this character will release the vial blanks from engagement with the fingers 15 n one or" the bars and pcrinit the same to roll along the hopper bottom into engagement with the next series of fingers. By means of this construction and operation, a gradual teed of blanks is insured, and the rate of feed may be so controlled that the hopper operates in timed relation both with the necking machine and the bottoming machine.

At its delivery end, the hopper may he provided with a chute 35 adapted to deliver the blanks directly onto the supports on the endless carriers at of the bottoming machine. Passage of the blanks to the chute may be controlled by means of a sliding gate 36 .rcciprocated by a bar 37 suitably secured thereto and extending transversely of the hopper through elongated openings 38 in the opposite sides thereof. The opposite ends of the bar 37-are in turn suitably secured to one end of the lever 39 each having a pivotal mounting 40 for their opposite ends. Intermediate their ends the levers are joined to pitman rods 41 secured to a transversely extending operating member l2. This operating member may in turn be con nected to one ot the T levers 18 so the gate -36 will be elevated and lowered in accord ance with the movement of said lever.

The chute 35 may also be provided with a stationary side 43 and an adjustable side 44:. There is also preferably provided a guard l-i) carried by the bracket 46 tor preventing the vial blanks from being delivered bcyond the supports 5.

Figures 5 and 6 illustrate clearly types of blanks adapted to be operated upon by the bottoming machine ted thereto by the hopper. The blanks shown in Fignree are adapted for the production of widemouthed vials.

It will be apparent that the provision of a hopper of this nature makes it possible to use the vial bottoming n'ia"hine independently of the necking machine. \Vhen this is done, the vial blanks, either necked or un necked, may be manually placed in the hopper and the operation of the nicchanisn'i employed in connection therewith will insure an orderly delivery oi the same.

The present invention is a division oi our copending application, Serial No. 338,179, filed November 15, 1919.

The advantages of the present invention arise from the provision of a feed mechanism adapted to cooperate both with a necking machine and a bottoming machine to insure the proper transfer of the vial blanks.

Further advantages of the present inven tion arise from the provision of a hopper adapted to receive a plurality of vial blanks and feed the same one by one in time sequence as required.
