My invention comprises a comprehensive machine for feeding bottles over a case, retaining the bottles elevated at a high level until a sufiicicnt number are grouped together in a basket type holder to fill the case and then automatically dropping the bottles into the case. The bottles are retarded in their drop so that they may not be broken, cracked or injure the case. The cases are automatically fed to the machine directly below the bottle holding basket and after being filled are automatically discharged from the machine.
Described and outlined more fully the machine has a bottle feeding belt or apron with a series of distributing passages with mechanism to distribute the bottles sidewise to a plurality of passages from a substantially single entrance. The bottle holding basket has a series of segmental hinged tracks to support the bottles so that they may be passed beyond the apron to a position above the case, the bottles being pressed along by succeeding bottles shoving them into position. lhe bottles cannot drop into the case until the bottle holding basket is completely filled when an electric circuit is established releasing a trigger which allows the tracks to swing downwardly and drop the bottles through a contracted resilient chute.
The empty cases are fed intermittently to the machine by a high cross conveyor on to a balanced table. This table becomes depressed when the bottles are loaded therein and is immediately carried out of the machine on an endless belt type of conveyor. I show an electric drive for the. intermittent cross conveyor having an electric motor therefor with a circuit breaker so arranged to break the circuit when a case is in position'to be loaded and thus stop the moveholding basket having spaces for a plurality of bottles in accordance with the size of the case. andthe number of bottles to be placed therein in accordance with the particular trade, retaining the bottles in the basket until it is completely filled and then automatically dropping the bottles through restricted chutes into the bottle cases. The objects also include restraining the bottles from being fed into the basket until the bottles are released from the basket to drop into the bottle cases and the tracks are again in the original position. A further object is in the automatic feeding of cases to and away from the machine.
My invention will be more readily understoodv from the following description considered in connection with the drawings, in which:

Fi 12 is a detail similar to Fig. 11, showing t e making of the-circuit by the rise of the balanced case table.
Referring particularly to Figs. 1, 2 and 3, the machine is housed in a framel, having base longitudinal bars 2, intermediate bars 3, top rails 4, front posts 5, intermediate posts 6, rear posts 7 back leg 8 and cross grid 9 and front bar 10. These are preferably formed into either a east, side frames suitably connected and braced together or by structural bars secured together to form a solid machine frame.
The bottle feeding and distributing mechanism is constructed substantially as fol lows, having reference particularly to Figs. 1, 2, 1. An endless conveying belt or apron 11 is mounted on the driving roller 12, and idler roller 13, positioned crosswise in the frame so that the upper surface of the belt passes above a belt supporting web 14 built into the frame transversely of the belt or apron. The belt travels in the direction of the arrow indicated adjacent thereto in Fig; 4 and is driven b the belt 15 operating over a ulley 16 on the shaft 17 of the driving roller 12, the said belt being operated by a drive pulley 18 mounted on a transverse shaft 19 as will be hereafter set forth.
A series of guide rails 20 are positioned longitudinally of the machine, being attached to the front bar 10 and the stop bar 21 at the back of the machine above the top of the frame so that the rails extend forwardly over the belt as indicated in Fig. 4. The outer rails are drawn inward in a plurality of curves 22, formin the straight guide rails 23 at their forwar end, thereb making a feeding-in throat 24 at the forward end of the machine over the belt. The machine is constructed with four passages 7 25 between the guide rails 20 so that four rows of bottles will be fed over the cases and the central rail has a diverting nose 26 formed by spreading the guide rail located in the central position of the machine. This 75 nose has a pivoted deflecting finger 27 having a spreading .base 28 and secured to the nose by the pivotpin 29. The ends of the intermediate guiderails 30 have similar deflecting fingers on their forward ends to so shift the bottles on each side of the saidrails between the outer rails 20 and the mid position rail 31.
The manner of operation of the feeding apron and distributing passages is substant- 8B ially as follows :The bottles may be fed by any type of mechanism into the machine to enter the throat 24:. If the deflecting finger 27 is in the position shown in Fig. 1, the bottles will be fed to the opposite passage and engage in the spreading base 28 swinging the finger in the opposite direction. The bottles will then be engaged by the deflecting fingers on .the ends of the intermediate guide rails 30 and deflected either to the left or to the right according to the position of the finger to locate the bottles in the several passages between the guide rails. It will thus be seen that the bottles enterin through the throat are alternately deflected left and right and that these bottles are likewise again deflected, each bottle in an alternate direction so that the bottle basket will be uniformly filled.
The bottle holding and dumping basket is constructed substantially as follows, having reference particularly to Figs. 1, 4, 7, 8 and 9. As above described, the longitudinal guide rails 20,30 and 31 are extended to the stop bar 21, forming a bottle holding basket designated generally by the numeral 32. The outside rails 20 are provided with recesses' 33 formed in sections with lugs 34= therebetween, said lugs having bushings 35 through which may be inserted lengthwise the rock shafts 36. The intermediate guide rails 30 have depending lugs with bushings 35 therethrough in which are located similar rock shafts 36. These rock shafts have a series of tracks 38 formed of angular plates with a wearing strip 39 extending upwardly. These tracks are shown secured to the rock shafts 36 by pins 40.
A series of bridging plates 41 are secured to the upper edge of the front bar 10 and extend close to the belt 11 as it passes over the driving roller 12. These plates carry the bottles from the belt to the tracks 38. Narrow cross bars 42 are secured across the frame of the machine and carry rings 43 Kit ' occupy the position shownin having spring wires 44.- attached thereto forming a resilient contracted chute 45 bethe outside guide rails 20 and interme ate guide rails 30. These stop sprin s normally i'g. 8 being 1261181011611, to retract to such position.- Depressions 48 are formed in these rails so that the fingers 46 may swing therein when the tracks are in their upper or carrying position shown in Fig. 8. a
The rock shafts and hence the dumping tracks are controlled substantially as follows:
their lower ends to the latch bar.
Having reference particularly to Figs. 1,
.3, 4, 7 and. 10, a cam 49 is secured to the end of each rock shaft, preferably in an adjustable manner. being held in position by-a set screw 5() and as the tracks are illustrated as dropping .in different directions of movement, the cams face in opposite directions. A latch bar 51 is supported'from standards 52 secured to the cross grid 9 by means of adjustable links 53 pivoted at 54 to the tops of the standards and swivelly connectednat e pivot pins are preferably readily removable so that the links the be accurately adjusted in length by threa ing one into-0r out of the other in the manner of turnbuckles. Tension springs 56 are-positioned between the pin 55 and the cross grid '9 normally drawing downwardly on the latch bar and thereby pressing the cams 49 into the position shown in Figs. 1 and 3, thereby holding the tracks 38 in their horizontal position as shown in Figs. 1 and 8, so that the bottles may be fed into the basket through the medium of the apron 11 causing the following bottles to press the leading bottles forward.
The electric trip mechanism to dump the bottles is constructed substantially as fol lows, having reference particularly to Figs. 1, 4 and 10':-A latch hook '57 is secured to the back face of the latch bar 51 and is engaged by a hooked head 58 mounted on the armature59, of an electro-magnet 60, whichlatter is supported in a housing 61 mounted on the cross grid 9. A series of push button switches 62 are mounted on the front face of the'stop bar 21 in position to be engaged by the bottles as they are pressed into the ma.- chine.
The electric circuit is shown particularly in Fig. 10 and is constructed as follows Electric leads 63 form a circuit from the source of power 64 through the electro-magnet 60 and through each of the switches of the push button type 62.- These switches are all m series-so that itianece'ssa for'them all'to be eased-berm the circuit is established. Therefore the bottles' must bepressed completely and ti htly'into the bottle hold-' ing basket 32 so t at jthere will be as many bottles as there are chutes 45 and as are required to",fill the case, and moreover, the
bottles will be properly centered. When the bottles in the difierent passages 25 press their individual push button to establish the circuit, the electro-magnet is energized with drawing the armature and hook 58, thereby releasing the latch hook 57 and allowing the bottles to drop, moving the tracks from the position shown in Fig; 8 to that shown in ig. 9 and shifting the cams 49 from the position shown in Fig.3 to that of Fig. 7. Thebottles are thus dumped into 'a case and in the rocking movement of the rock bars the stopping fingers 46 are moved, from the position shown in Fig. 8 to that shown in the stop springs 47 Fig. 9, thus thrustin across the bridging plates 41 and thus preventing the bottles being filled into the bottle holding basket.
When the bottles have been dropped into the case the springs 56 draw the latch bar 51 downwardly and rock the cams 49 from the position shown in Fig. 7 to that shown in Fig. 3, in which operation-the latch book 57 and the hookedhead 58 become engaged due to a compression spring 65 pressing the armature of the electro-magnet forwardly. Thus the tracks are locked to permit. feeding of the bottles and there is no barrier in their way.
The mechanism for feeding the cases into the machine is constructed substantially as follows, having reference particularly to Figs. 1, 2, 3, 5 and 7 :A conveyor frame 66 has an outside pair of legs 67 secured to the floor of the building and a bracket 68 secured to the side of the main machine frame preferably to the posts 6 and 7. A series of rollers 69 are mounted in the frame 66 on each side thereof and are freely rotatable and conveniently placed whereby an attendant may place empty cases thereon. Sprocket gear wheels 70 are journaled preferably by having shafts 71 and 7 2journaled respectively to the legs 67 and the bracket- 68. A sprocket chain 73 having feeding pins 74 are operated by the sprocket wheels to feed the empty cases into the machine as indicated by the arrow in Fig. 3. The driving mechanism is hereafter described in detail.
' The balanced table for supporting the empty case and in lowering it to the feeding- .out conveyor is copst'ructed' substantially as follows, having reference particularly to 'rails are connected by a drop brace 78 connected from one side to the other in order to hold the side panels rigid, one in regard to the other causing uniform motion thereof. Inwardly extending arms 79 and 80 are attached to the side rails and extend close to the centrally ositioned out-feeding conveyor hereafter escribed. Guide plates 81 are pivotally connected to the arms 79 as indicated at 82 and have rearwardly projecting shanks 83.
A pair of lever arms 84 and 85 are pivoted by means of pivot pins 86 on brackets 87 secured to the intermediate bars 3 of the main frame of the machine. The lever arms 84 have counter-weight arms 88 connected therewith with counter-weights 89 adjustably mounted thereon by means of set screws or similar devices. A link 90 connects the two lever arms 84 and 85 and on the pintles 91 carries rollers 92 which bear on the un der-surface of the side rails 76 of the table 75, thereby always tending to elevate the table.
The out-feeding conveyor is constructed substantially as follows, having reference particularly to Figs. 1, 2, 3, 4, 5 and 6:A main shaft 93 is mounted in the frame and is shown journalled at the top of the back leg 8 where it joins the intermediate bars 3. This shaft carries the main pulley 94 through which a drive is carried to the machine operating the sprocket gear wheel 95, and by means of the sprocket chain 96 the driven sprocket gear 97 fixed on the transverse shaft 19; As formerly mentioned the drive is continued by the belt 15 operating the pulley 16 which in its turn transmits motion to the apron 11.
The sprocket chain 96 carries a series of projections 98 which project upwardly through a slot 99 in a plate 100, which plate is supported by a pair of brackets 101 on the fixed rod 102 extending transversely across the frame. The plate thereby serves as a support for the boxes of filled bottles after the table 75 has been depressed by the weight of the filled bottles. The shanks 83 of the guide plates 81 contact with the rod 102 and thereby release the guide plates from the edge of the box or case as shown in Fig. 6 so that the move ment of the sprocket chain 96 in the direction of the arrow moves the filled case out o l? the machine.
The electrical control and motor drive for the feeding-in mechanism is constructed substantially as follows, having reference par-- ticularly to Figs. 2, 3, 5, 11 and 12 :-An electric circuit breaker designated general ly by the numeral 103 shown particularly in Figs. 3, 11 and 12 has a fixed insulating plate 104 secured to a bracket 105 which is carried by-a longitudinal brace 106 secured between the intermediate posts 6 and the rear post 7 on the opposite side of the machine from the feeding-in conveyor. 'The bracket 105 carries a pair of lugs 107 to which is pivoted a switch lever 108 having an outstanding projection 109 on one side of the pivotal point and a plug contact 110 mounted on the other end on an insulating plate 111. A spring 112 is tensioned to normall establish an electric circuit between t e socket members 113 and 114, the member 113 having a binding post 115 connected to a lead wire 116. The other lead wire of the circuit 117 "is connected to a binding post 118 having a cap 119 on the same side of the insulating plate 104. A strut 120 is secured to the balanced table 75, being attached to the side anels 76 on the opposite side from the fee ing-in conveyor and carries an insulating strip 121 at its upper end with a coducting bridging bar 122 which is adapted when in its uppermost position as shown in Fig. 12 to bridge the space between the socket member 114 and the cap 119 and in such position establish an electric current which will operate the electric motor.
The motor is designated generaly by the numeral 123 drives a gear 125 on the counter-shaft 126, which latter has a gear 127 meshing with the gear 128 on the shaft 72 which drives the sprocket wheels 70 of the feeding-in conveyor sprocket chain 73. The action of the circuit breaking mechanism above described is substantially as follows :If the table 75 is in its uppermost position and no box is positioned thereon, the circuit will be established through the leads 116, post 115, socket member 113, plug 110 socket member 114, bridging plate 122, cap 119, post 118 and electric lead 117 to the electric motor, which will operate to move the feeding-in conveyor and when a case contacts with the projection 109 of the switch lever 1.08, the circuit will be broken as shown in Fig. 3 by the withdrawal of the plug 110 from the socket members 113 and 114. Thus the feeding conveyor will be brought to rest. A coil spring transmission 129 is used to transmit motion from the motor to the pinion 124 so that the abrupt stopping and starting of the motor will not cause any damage. As shown in Fig. 3, the box on the table 75 has been completely shoved over by contacting with the case on the feeding-in conveyor mechanism. Hence after a case has been filled and lowered on to the feeding-out conveyor and the table has been elevated to its uppermost position, an empty case is in position to be immediately fed forward thereon.
It will thus be seen that I- have provided a machine for loading bottles into a' case which is automatic in that the bottles are fed into the bottle holding basket, retained thereinuntil all the rows are completely and by means of the pinion 124 full when the bottles at the end of each row press against the electric switches making a series circuit which actuate the electric trip mechanism alowing the bottles to drop into an empty case. The weight of the loaded case causes the supporting table to move downwardly and the case to be removed by the out-feeding conveyor. Also on the upward movement of the table an empty case is fed into the machine by starting the electric motor is stopped sttopping such conveyor and when the case is in position the electric motor is stopped stotpping such canveyor.
