Application filed January 16, 1915 Serial No. 2,746.

To all whom it may Concern:

Be it known that I, FRANK O. WOODLAND, a citizen of the UnitedStates, residing at Worcester, in the county of Worcesterand State of Massachusetts, have invented certain new and useful Improvements in Automatic Bottle-Feed Mechanism for Labeling- Machines, of which the followingis a specification. I My present invention relates to a novel construction and organization of mechanism,-

more especially adapted for automatically conducting andfeeding bottles or other containers and similar articles, in labeling ma-' chines, in which a rotary or traveling carrier is employed; the prime object being to provide a-mechanism which can be operated at a high rate of speed with practical efliciency.

Another object is to provide an automatic bottle feeding means actuated by the moving bottle carrier, and controlled by approaching bottles or the like, as more fully hereinafter; explained.

Minor jobjects and features of invention are set forth in the following detailed description; the particular subject matter 1cilaiilmed being hereinafter definitely specie In the accompanying drawings, Figure 1 represents an elevation view of mechanism embodying my invention as applied to a labeling machine. Fig. 2 represents a horizontal section orplan view of the conveyor, rotary earner and. ad acent parts, on a some what larger scale. Fig. 3 is a sectional View showing the barrier at, the end of the feed;-

" way. Fig. 4 shows the front and side of theing-in lever. Fig. 6' is a pla'nd-iagram-on Somewhat larger scale illustratlng the action 5oscribed in my prior LettersPatent, numbered 1,113,85 4 a nd 1,113,855 but it w ll be underpushing rest separate from other parts.

Fig. 5 is a separate front view of the feedof the discharging deyi'ces. Fig-7 is aplan diagram illustrating the action of the feeding devices. Figs. 8 and 9 are plan views illustrating modifications in thejconstruction of the feeder elenient and its locking devices.

The labeling mechanism to which my invention as herein'illustrated is applied," is in general character substantially as de- Fig. 1.

' the freshly stood that the invention Imay be'employed with labeling mechanism of other construction, and of a character to which the same may be applied without substantial change in the nature of the invention defined in the subjoined claims.

Referring to the drawings, the numeral 10 Ind cates the frame or supporting column havlng a broad foot or. base; 12 indicates the moving carrier or rotary table mounted to revolve about a vertical axis or shaft 1' fixed in said column. The carrier has an annular horizontal top surface that is provided with a series of rests or pusher devices 1 1 fixed thereon and arranged at intervals near lts periphery, and adapted for supporting WO CES ER,- MAS'sACHmi" Specification of Letters Patent.

7 Above and 'adjacentto thegface ofthem'ar.

rier 12, along the portions where the bottles or articles to be labeled are entered thereon, and where discharged therefrom, I provide curved stationary guards or fenders 27, 28, 29 and 30, forming inner and outer walls inclosing the carrier path or way along which the bottles are advanced; said guards being of suitable form and height to prevent the bottles from tipping over or from lateral displacement as they are moved along by the propelling mechanism.

Near the side of the carrier there is arranged a feed-Way 31 and a discharge-way 32 relatively disposed substantially as shown; the feed-Way comprising suitable side guards 31 and a traveling conveyer or endless belt 31 that runs over a pulley 33 having its axis support mounted upon the stationary frame or stand 35, connected with the machine. standard 10, or some permanent part of the frame. The dischargeway 32 is arranged in connection with the carrier exit, and comprises side guards 32 and a traveling conveyer or endless belt 32 that runs over a pulley 34 having its axis shaft supported upon the stand-35, preferably parallel with the axis of pulley 33. The outer end loops ofsaid conveyer belts respectively run over pulleys 36 and 37, which can be located at any convenient distance away from the stand 35; and suitable intermediate supports or rollers are provided for sustaining the upper run of saidbelts. The conveying surfaces are disposed approximately level with the top face of the carrier 12.

The parallel guards 31 and 32 are arranged on either side of and above the conveyer-belts'to embrace a guide-way space, the width of which is slightly greater than the diameter of the bottles or containers to be conveyed, and within said space the bottles are caused to travel while standing upon the moving belt. The driving power for operating the conveyer-belts is applied to the axle of one of the pulleys, by any suitable means, while the axles of the pulleys 33 and 34 at the adjacentends of the conveyers are provided with sprocket gears and connected by a drive-chain 38 or other suitable operating connections. The proportion of the sprockets, or connecting gearing, is preferably made so that the feed-way conveyer will travel at slightly greater velocity than the discharge-Way conveyer; such velocity being gaged at a speed sufficient to normally bring forward a supply of bottles or the like equal to the full capacity of the carrier and labeling mechanisms.

Suitable tables T T may be provided at the outer ends of the feed-way and discharge-way conveyers, to facilitate handling the bottles, or said conveyers may be arranged to take and deliver directly from and to other machines in a bottling plant.

At the inner end of the feed-way 31 a transverse guard or barrier 40 is provided, and a lateral pass-way 41 leading from the conveyer to the carrier path or into the space between the curved guards 27 and 28,

as best shown in Figs. 6 and 7. An intermittently operating means is combined with the pass-way and carrier for automatically forcing successive bottles from the feed-Way conveyer to the carrier. The inner end of said pass-way is .preferably curved or inclined toward the direction in which the carrier moves, thus giving a forward trend to the incoming bottle as it is projected onto the carrier.

' The barrier 40 is preferably of skeleton structure, (see Fig. 3) and the feeding-in device .42 is arranged adjacent thereto for driving or shunting the bottles successively from the feed-way 31 through the passage 41 and into the path of the advancing pushing rests 14. In the present instance said feedingin device consists of a horizontally swinging arm or lever fulcrumed upon an upright shaft or axis stud 43, and provided at its end with fingers or prongs 44 that extend between the bars of the barrier and sweep along the passage way 41, when operating.

The furcated end of the lever is made of suitable shape and size for taking or shunting a single bottle only at each forward stroke thereof. The fingers 44 may be stiff, or can be jointed to the arm by a hinge or pivot 45 and provided with a back stop 46 and a retracting spring 47, (see Fig. 5) so that during the backward swing of the arm the fingers 44 can fold inward to pass any obstruction and then assume normal relation as the arm reaches its primal position. Actuating means is provided for working the feeding-in devices in cooperation with the carrier 12, and at intervals to correspond with the spaces of bottle-pushing rests 14.

Said means includes a roller 50 that runs 1.

against cams or shaped surfaces 51 upon the rim or periphery of the movable carriers 12, and having suitable connection with the feeder, either directly, or as illustrated in Fig. l, by an angle lever 48 fulcrumed upon a stationary support, one of its arms being connected by a rod 49 to an arm fixed on the upright shaft 43, While its other arm has the roll pivoted thereon. A spring 52 is suitably combined with the feeding-in devices for exerting pressure and moving the lever in oppositlon to the cam.

A bottle-actuated catch device is arranged at or near the end of the feed-way 31 for holding the feeding-in arm 42 at outward idle position, except when a .bottle or the like is brought into position to be transferred to the carrier. As shown in Fig. 7, a spring-pressed movable catch-member 54 is arranged to move past a lug or detent on the arm 42 when the latter swings back, and to thus prevent action of the feeding device until said catch is retracted; the retraction being effected by a feeler member 55 that projects into the feed-way and is engaged by the approaching bottle just previous to its reaching the barrier 40. The faces of the engaging members may in some instances be made to merely latch one against the other as a stop; but preferably said parts are formed as interlocking members or counter-matching offset lugs, as best shown in Fig. 7 at 56, so that the arrested feeding-in lever 42 temporarily prevents withdrawal of the catch-device and feeler 55, while the catch-device prevents forward movement of the feeding-in lever. A slight backward movement of the feeding-in lever 42 is required for disengaging the interlock of'the lugs from each other, and then the catch device can be retracted to permit the feeding-in lever to swing forward and propel the bottle through the lateral pass-way.

proper relation for engaging with the feed-- ing-in member, an example of which is illustrated in Figs. 8 and 9.

58 indicates a swingin guard member or gate hingedly supporte upon the inner guiding wall 31 and projecting in alinement therewith partially across the lateral opening at the junction of the feed-way 31 and pass-way 41; the purpose of which gate is to keep the bottles in line until they reach the barrier40. A spring 59 is provided for giving a yielding force upon said gate sufficient to normally maintain the alinement, but weak enough to permit the gate to swing out of the passage when the feeder lever 42 acts.

60 indicates a swinging spring-pressed alinement with the pushing rests 14, or is completely up to the required position before taking the carrier movement.

62 indicates the feeler devices for actuating the picker-stop and controlling the labelfeed action. Said feeler extends into and alongthe carrier-path in such manner that an advancing bottle or the like as it comes through the guiding pass-way 41 and as-.

sumes its position and advancing motion in the carrier path will force back the feeler and thereby control the acting engagement or non-engagement of the stop members.

64 indicates spring fingers, or means arranged upon the fenders 27 and 28 for giving a moderate degree of friction against the moving bottle or article, to insure that the bottle is close seated against the pushing rest 14 before the label-gripping-device is brought into contact therewith.

' For discharging the bottles from the carrier 12 the fenders or guards 29 and 30 are continued in a compound curve to connect with the guiding members 32 of the discharge-way, as illustrated in Figs. 2 and 6.

Between the side of the carrier 12 and the discharge conveyer there is arranged a whirler disk 65 or flat horizontal circular plate that is rotatable on a vertical axis spindle, and operated by having its periph eral edge in rolling contact with the edge of the carrier, or by other means, whereby rotary motion is imparted to said whirlerin the direction indicated by arrow. The fiat top surface of the whirler is substantially level with the surface of the carrier and conveyer.

The guard fenders 29 and 30 inclose a curved exit-way from the path of the carrier to the discharge-way across the advancing side of the whirler. vided with an opening to allow the series of pushing rests 14 to pass through, but is made continuous above the height of said rests. It is provided with a swinging springpressed gate 67 at'its lower edge that keeps the bottle in proper relation to follow the discharge passage, but allows the pusher rests to pass in their regular path.

The portion of the guiding fender at the outer curve near the whirler may be provided with a swinging bar or section 68 (see Fig. 6) pivoted at its leading end and adapted to swing inward at its other end, and having a spring 69 combined therewith for giving a yielding inward pressure that tends to force the bottles toward the opposite guard as they leave the pusher rest and approach the whirler plate. In Fig. 2 the guard fender 30 is shown with the swinging bar 68 omitted, since such construction may in some instances be employed.

The curved guards or fenders 29 and 30 may in some instances be made of the same height as that shown for the'in- feed guards 27 or 28, which is about the height of the .body of the bottle, more or less. But as an effective improvement said guards, along the discharging side of the carrier, or a portion thereof, may be provided with upwardly extended inwardly overhanging top portions 29 and 30", each having a guiding edge disposed at about the height of the The fender 29 is proneck of the bottle just below the swell of its members being arranged with a space S between .their top edges sufficient for loosely embracing and guiding the necks of the bottles; thereby obviating liability of a bottle being tipped over -while carried rapidly along the path and across the whirler '65 to the discharge conveyer 32.

Fig. 2 illustrates the guards as made without, and Fig. 6 as made with the extended top or neck-guiding portion.

Fig. 8 illustrates a modification in the construction of the feed-controlling catch and interlock members; wherein the feeler dicated at 56*.

the feeding-in lever 42 is provided with rigid instead of hinged prongs 44, and with a forwardly projecting member or finger 42 that extends in front of the bottles and serves to facilitate the rapid transfer of the single bottles. The lever is also made with an attached armor member having the camc'ontacting roll 50 mounted thereon for actuating the feeding-in lever directly from the cam surfaces 51 formed on the edge of the rotating bottle carrier 12. The catch-.

piece 55 is also made of somewhat modified shape and its inner end pivotally fulcrumed upon the barrier frame, the engaging lug 56* being at the outer end of said catchpiece. M

The portion of the fender 30 along the edge of the carrier 12, maybe of skeletonized structure, or formed of a number of longitudinal ribs with open spaces betweenthem, so that any waste material or chips of glass falling upon the carrier, will be thrown off through or beneaththe open fender, and without passing to the bottledelivering conveyer.

In the operation; the bottles are placed in any manner in upright position upon the moving feed-way conveyer, and are thereby brought forward to the barrier or position B indicated by dotted lines on Fig. 7 where they are temporarily arrested by the locked catch device until the feeding-in lever or member 42 is, by the action of cam 51 and connections 4849, moved slightly backward sufficient to release the interlock. Then the travelingconveyer-belt 31 causes an advance-of the bottle up to the barrier, or to position B forcing back the finger 55 and unlocking the catch device 54; thus permitting the spring 52 to throw forward the feeding-in lever 42, the movement of which projects the bottle along the face of the barrier 40 through the pass-way 41 to the position B within the path of the carrier as defined by the guard fenders 27 and 28, and in line with advancin' pushers or rests 14, one of which then push s the bottle forward with the. movement of the carrier until the bottle passes between the guards or fenders 29' and 30, which guards crowd the bottle from in front of the pusher 14 and shunts it onto the whirler 65, the rotary motion of which gives to the bottle an impetus that delivers it onto the traveling belt 32 of the discharge-way conveyer 32, by which it is carried to the packers table T or any predetermined place of delivery. In like manner successive bottles are passed through the operation as fast as the series of pushing rests 14 on the moving carrier can take them away from the'position B to which they are continually successively fed by a synchronous action of the automatic feed mechanism. ,If a bottle is absent from the position'B 011 the conveyer the feeding-in lever 42 and trip 55 remain locked and there is no action of the feeding-in mechanism. Hence, while the mechanism can operate fed to the full .capacity of the series of pushing rests, no derangement-in the perfection of action, or quality of the work, is liable to occur should the supply of bottles be irregular, or occasional bottles missing from the regular succession.

When the machine is running at a very high speed the bottles come to the barrier 40 with such velocity that there is practically no delay by the locking action of the catch-device 56 and feeding-in device 42, except when the approaching bottles are at some distance apart, or varying in such distances, then the locking and unlocking is effective for regulating the instants of feeding-in action to properly correspond to positions of supporting or pushing rests on the continuously moving carrier.

As I am aware that some mechanical changes and modifications may be made in practising my invention, by persons skilled in the art, without departing from the spirit and scope of the invention as expressed in the claims, it will be understood that I do not wish to be limited. to the particular form of construction herein shown.
