To all whom it may concern:

Be it known that we, EDWARD H. WEATHER- HEAD and THEODORE H. SQHUTT, citizens of the United States, and residents of Cleveland, county of CuyahOga, State of Ohio, have jointly invented a new and useful Improvement in Mechanism forFeeding Bottles and Similar Articles, of which the following is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

The present improvements relate in general to bottle filling machines, and more particularly to means for feeding the bottles to the fillingmachineproper. The usual method of transferring bottles to the holders of a filling machine is to pass the bottles adjacent to the machine upon a suitable conveyer, and to then provide means which are adapted to transfer the bottles from this conveyor to the holders. For this purpose a positively actuated mechanism is of course preferable, but if such a mechanism is used it is necessary to have not onlya moving membergbut also a fixed guideway adapted to cooperate with the member to transfer the bottles, and

as the bottles vary greatly in size, even those that are rated at the same capacity,

and as the rotatable member is provided with a plurality of projections, it has heretofore been practically impossible to provlde transferring mechanism of this positive type which will not occasionally crush a bottle between'one of the points of the rotatlng members and the guideway. It is the 'object of the present invention to rovide a positively actuated transfer mec anism provided withmeans which render it impossible for the mechanism to'ever seize and crush a bottle during the transferring operation. To the accomplishment of the foregolng and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and-the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of venous mechanlcal forms 1n which the principle of the invention may be-used.

around against the curved able holders, one end of the conveyor, and the transferring mechanism between the same; F 1g. 2 is a similar plan view, but

showing the mechanism in a different operone of the details of the machine.

In'Fig. 1 there are shown the holders 1 o the filling machine, such holders being c011- jointly movable in a circular direction as indicated by the arrow, and having side rails 2 formed as shown. Adjacent to the-holders there is provided a conveyor 3 which may be. of any suitable type, although preferably constructed as here indicated, and consisting of a plurality of metal plates or links flexi- .bly joined together.

lntermedlate the holders and the con-- veyer there are provided bottle transferring means comprising a curved guideway 5 surrounding a rotatable element 6 which is preferably in the form of a starwheel having a plurality of equally spaced projections 7 and a similar number of recesses 8 formed between the projections, each recess or pocket being adapted to receive abottle 10. Mounted on the lower side of each projection 7 1s a roller 11 adaptedto be contacted by the extending side 2 of the holder upon the movement of the two into a certain. position, each holder thus rotating. the starwheel through a certain angle. The starwheel is thus positively driven insynchronismwith the holders, and the recesses in the starwheel are brought into accurate cooperating position with respect to the holders so that bottles may be moved from thestarwheel onto the holders in the manner indicated in the three holders at the left of Fig.1. The starwheel engages the bottles as they are brought along the conveyer 3, each recess in the starwheel receiving a single bottle, which is then moved guideway 5 until positioned on the holder.

The bottles are placed upon the conveyer by operators who do not always take time to space'the bottles accurately, and it is. thus necessary to provide bottle. spacing means for regulating the supplying or feeding of the bottles by the conveyer to the transferring mechanism. The necessity for such means lies in the fact that if a bottle has been brought on the conveyer to a point directly between the corner 30 of the guideway and the nearest projection 7 on the starwheel, the latter, when rotating, will seize the bottle between these two points and crush the same. This difficulty may of course be obvi- 10 ated by the use of a yielding corner at this point in the guideway, but this merely permits the bottle to be pushed out of position and the resilient mounting of this yielding corner causes the bottle to be snapped back 5 as soon as the point on the starwheel has passed, which often upsets the bottle and causes it to break in its fall.

e have accordingly provided means which positively prevent a bottle from being'moved into the starwheel by the conveyer except when a pocket or recess on the starwheel is alined with the path of movement of the bottles on the conveyer, such path being determined by guides or sides 12 on the latter. Such means include a pivoted gate or arm 13 pivoted at the point 14, and adapted to be normally maintained with the arm 15 extending into the path of move ment of the bottles as indicated in Fig. 2. At the end of such arm is mounted a roller 31 for contacting the bottles. The gate is maintained in this position by means of suitable resilient means, preferably in the form of a spring 18. The starwheel is provided W1l3l13. plurality of cams or fingers 16 on its under side, there being one such finger for each projection or point on the starwheel. These projections are adapted to successlvely engage a roller or post 17 mounted 4a upon the gate, and to then temporarily swing the gate into the position shown in Fig. 1, at which time a pocket in the starwheel will be alined with the path of movement of the bottles on the conveyer, and a bottle will accordingly be moved into each pocket at this time. As soon as this pocket in the starwheel is passed out of linewith the conveyer the spring 18 will return the gate 13 to. its extending or bottle-blocking 59 posltion, thus preventing movement of another bottle onto the starwheel until the next succeeding cam 16-engages the roller 17. It is also highly desirable that the bottles be moved into contact with both sides of 85 the recess or pocket in the starwheel in order that the starwheel may properly act to pos1t1on the bottles upon the holders, and we therefore provide upon the pivoted gate 13 an arm 20 which is pivoted thereon and 60 free to swing across the same for the purpose of forcing back any bottle which may have been moved into such position when the gate 13 is inoperative. A bottle might otherwise prevent the return of the gate which is entirely spring. actuated on its return and this bottle would then be too near the starwheel and would be moved too far into the same. The action of this arm 20 is as follows: Upon the return of the gate 13 by the spring this arm 20 Will be swung into a position at an acute angle to the position of the arm as shown in Fig. 2. Upon the movement of the next point of the starwheel into substantial alinemen't with the upper of the guides 12, the roller 11 beneath this point will engage the curved outer surface of the arm 20 and will swing the same into contact with the lower edge of the rail 15 on the gate 13. This action of the arm will move back any bottle which may have been 30 positioned between the gate 13 and the side of the guideway, thus maintaining such bottle in such a position that upon the removal of the gate the conveyer will move it into its proper position in the recess in the starwheel alined therewith.

It is equally important that thebottles be moved smoothly onto the holders and be properly positioned thereon, and for this purpose we provide a second pivoted arm or gate 21 which is normally maintained in contact with the bottles as they come around the guideway in the recesses in the starwheel by means of a coil spring 22, the construction and position of which will be readily seen from Fig. 4. Thus, as each bottle is moved around the guideway 5 by the point on the starwheel, it is forced back into the recess until it has been moved to the back of the holder 1. The pressure of the starwheel on one side and of the gate 21 on the other prevent any wabbling of the bottle as it. is moved from the starwheel onto the holder.

The arm or gate 21 is pivotally attached 0 to the end of the outer guideway 40 as stated. In order to prevent excess movement by the arm, which would cause it to strike a bottle with great force, there are provided limiting means, preferably in the form of a jaw or lug 41 on the arm operating between two spaced stops or

jaws

42 and 43 on the guideway. The action of these stops will be readily understood, their sole function being to be engaged by the jaw 41, thus limiting the angular swing of the arm 21 to the desired-arc to give the most satisfactory operation with the bottles.

The lower guide 12 and the inner liner 23 of the guideway 5 are made removable in order to accommodate different sizes of bottles, and the starwheels will similarly be made readily removable from the central bearing post 25 for the same purpose. It

will, however, be unnecessary to change the bottle spacing means, which will still oper ate as before, since the bottles will still be in contact with the upper one, of the guides 12 and will still be brought to the same position with respect to the gate 13 as before.

' Our improved transferring means operate effectively to shift the bottles from the conveyer onto the holders or stirrups as they are sometimes termed and although in use on a number of machines, no case of breakage has ever occurred, nor have any bottles "been upset during the movement onto the holders.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as .regards the mechanism'herein disclosed, pro vided the means stated by any of the follow-in claims orthe e uivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention 1.
