49 Claims.

This invention relates to wrapping machines and particularly to the conveying mechanism for conveying a series of articles to be wrapped, in line along a predetermined path. The conveying mechanismalso includes means for movingsections ofthat line of articles onto av wrapper which is to be wrapped about the articles.

This application is a division of 'my application Serial No. 94,438, filed March 13, 1926, now

Patent No. 1,818,496 for a Packaging machine.

' One of the objects" of this invention is to con-.-

vey a series of articles arranged in line with each other along a predetermined path and at various rates of speed and for the purposes which will be more clearly, set forth in the specification.

Another object-of this invention relates to the feature of having the articles carried by a plurality of conveyers onto the wrapper which is to be wrapped about the articles. A further object of this invention is to provide means for removing articles from the line of articles when the same are not in the desired relation with respect to each other. In the embodiment shown in the drawings, the articles are arranged in overlapping relation and'in the event some article does not overlap the one next toit, that article will be ejected. I

Other objects of this invention will appear hereinafter as the description proceeds, the 3 novel features and combinations being set forth in the accompanying claims.

Fig. 14 is an enlarged view of a portion of the mechanism shown in Fig. 13 with the parts thereofin a slightly 'difierent position of adjustment.

In my application Serial No. 94,438 previously referred to, I have described an apparatus for wrapping articles in an air tight package, as it is quite obvious that articles wrapped in this manner are better protected from heat and moisture than articles which will permit the entrance of air or moisture. The invention in that application is limited to the means or wrapping the articles, and not particularly to the conveying mechanism which conveys the articles into' a position to be wrapped or into a preliminary position from which the articles are taken and removed to a position on the wrapper.

, The present invention which was divided out of applicant's above mentioned application Serial No. 94,438, deals particularly with the preliminary feeding of the articles to the wrapping mechanism. This conveying mechanism is quite novel and enables even a fragile cake to be handled to the wrapping mechanism without breaking the same. In the drawings in this application I have illustrated the invention in a slightly difierent manner than in application Serial No. 94,438 in 5 order to more clearly bring forth the invention which is to be claimed herein.

In the embodiment of the invention shown in the drawings, the machine is shown as adapted to the purpose of wrapping wafers such as cakes or cookies, but it will be understood that the principle of the invention may be applied to the wrapping of a large-variety of articles. The wafers to be wrapped are arranged on edge in a conveyer trough, best illustrated in Figs. 1, 2.55

.1- 4 however, is greater than the total travel of the and 3. The conveyer trough comprises a pair of guides and a plurality of conveyer belts arranged between the guides. The guides are indicated by the reference numerals I and 2, the guide I being that which is closer to the observer in Fig. 1, and the guide 2 is that which is farthest away fromthe observer in Fig. 1. There are three conveyer belts. The first conveyer belt is of substantially the same width as the distance between the guides I and 2,- and is indicated by the refer ence'numeral 3. The next conveyer belt is the conveyer belt 4 which is substantially less in width than the distance between the guides I and 2 and finally there are the conveyer-belts 5, portions 7 of which are arranged on opposite sides of the conveyer belt 4. The conveyer belts 5 are each. 8f sullostantially the same width as the conveyer elt The conveyer belt 3 is trained over the pulleys 6 and I secured to the shafts 8 and 9 respectively, these shafts being in turn rotatably mounted in the brackets I0 and II secured to the guides I and 2. Conveyer belt 4 is trained'over the pulley I2 secured to the shaft I3 rotatably mounted irh the bracket I4, the latter being secured to the guide I. This conveyer belt is also trained over a pulley I5 secured to a shaft I6 which in turn is rotatably mounted'in the bracket I1. 1 The guides-I and 2 are carried by means of a supporting bracket I8, and the bracket I1 is also secured to the bracket I8 as illustrated in Fig. 1. A bracket I9 secured to the supporting bracket I8 carries a rotatable pulley 20 at the free end thereof, and this pulley 20 lies intermediate the pulleys I2 and I5, and the belt 4 is adapted to travel over the pulley20, as well as over the pulleys I2 and I5. It will be noted from-an inspection of Fig. 1 that by providing the intermediate pulley 20, a

I portion of the upper run of the belt 4 is 'in the same plane as the upper run of the belt 3, and that the portion of the belt 4 to the right of the first portion of that belt is inclined slightly downwardly due to the fact that the upper surface of the pulley I5 is not in the same horizontal plane as the upper surface of the pulley I2.

The belts5 are trained over the pulley 20 and also over the pulley 2I illustrated in Figs. I, 8, and 9 particularly, this latter pulley being secured to the shaft 22 which is rotatable in suitable bearings in the bearing support 23 mounted on the bearing bracket I8.

, The wafers, which I shall hereinafter refer to as cakes are placed in a V-shaped trough'24 in J- abutting relation as illustrated in Fig. 1, the cakes being placed in the trough 24 either by hand or by suitable mechanical means. The cakes travel down the trough 24 by gravity, and when they reach the bottom end of the trough; the same will rest on the upperrun of the conveyer belt 3 and the conveyer belt 3'wil1 convey the cakes to the right onto the conveyer belt 4, which in turn will carry the cakes onto the conveyer belts 5.

The belts 3, 4, and 5 each travel at a different rate of speed. The conveyer belt 4 travels at a greater rate of speed than the conveyer belt 3, but at a lesser speed than the conveyer belts 5. The. reason for the conveyer belts 5 traveling at a greater rate of speed than the conveyer belt 4 is that the conveyer belts 5 are intermittently operated as will be described later, whereas the conveyer belt 4, as well as'the conveyer belt 3 are continuously moving. The total travel of the belt belts 5 for reasons hereinafter.

In order to obtain the respective speeds for the conveyer belts 3, 4; and 5, I provide .a sprocket 25 on the shaft 3, sprockets 26 on the shaft I6, idlers 21' and a sprocket on the shaft 28 about which are trained the chains 29 and 30 in the manner best illustrated in Figs. 1 and 2. The shaft 28 is driven from the shaft 3I by means of the gears 32 and 33 secured to the shafts 23 and 3| respectively. The shaft 3| is driven in turn from the main drive shaft 34, shown in Fig. 4, by means of a chain 35 trained over a sprocket which will appear more fully on the shaft 34, idlers 36 and 31 and sprocket 38;

gears 39, 40, and H; and chain 42 trained over the sprocket 43 on the shaft 3| and over a sprocket 44 on the shaft 45 which carries the gear 4 I The direction of travel of the driving elements is indicated by means of the arrows in Figs. 1 and 4.

The cakes are indicated by the reference numeral 46, and the action of the conveyers in conveying the cakes is as follows: Y

The cakes on the conveyer 3 are arranged in substantially the angle indicated at.A in Fig. 1, but as the cakes are carried onto the conveyer 4, they are spread out more and at the same time are at a lesser angle to the horizontal except when acted upon by an exterior force other than the force which is exerted by the conveyer belts 3 and .4. One such exteriorforce is exerted by the belts 5 when the same are stationary. In

.other words, when the belts 5 are stationary, the

cakes move onto the conveyers 5 from the conveyer 4, and begin to pile up or stop. This stopping of the cakes as they arrive on the conveyers 5 causes the cakes to also pile up on the conveyer cakes may be carried onto the conveyer belts '5 to compensate for those which are taken'from the conveyer belts 5 to the wrapper which is to enclose the cakes or section of the line of cakes later on. The conveyer belt 3 travels at a rate of speed which is just about sumcient to keep a constant feed of cakes to the line of cakes without permitting a gap in said line, and perhaps the conveyer 3 will travel at just slightly a greater rate of speed than is actually necessary. The

conveyer belt 4 travels faster than the conveyer belt 3 in order to spread out the cakes while maintaining the cakes inthe proper overlapping relation.

It is obvious that if any one of the cakes falls flat on the conveyers 3, 4 and 5, it will, practically be impossible to stand this cake on edge as is necessary for wrapping and as is indicated at C in Fig. 1. Therefore, I provide meansfor ejecting each and every cake which is lying flat on the conveyer 3. This means is best illustrated in Figs. 1, 2, and 3. In these figures is shown a plate '41 which lies over the belt 3 and has portions 43 which lie on opposite sides of the pulley I2 which partially supports the conveyer belt 4. The plate 4.1 has an edge 49 disposed at an angle to the path of travel of articles on the conveyer and is of substantially the same thickness as the cakes which are to be wrapped as is more clearly 65.- upper edges for the pocket. At one end of the not ride over the plate 41, but will abut against the angular surface 48 and be drawn toward the guide in which I provide an opening 50 through which the .cake 46 is ejected, as is more clearly illustrated in Fig. 3. I

The conveyer belt ,4 travels just a little faster than is necessary to keep the conveyers 5 sunplied with cakes which are removed from the conveyers 5 to a, position above the wrapper which is to be wrapped about the articles.

01' course, it is desired that the articles occupy a substantially vertical position when they are removed from the conveyer and preferably inclined'slightly forwardly in the direction of movement of the conveyer belts 5, rather than backwardly. For this purpose I provide the rotating wheel 5| secured to the shaft 3|, and this carries a plurality of spring wipers 52 secured about the periphery of the'wheel 5|. Of course the rotation of the shaft 3| causes the wheel 5| t rotate in the direction indicated by the. arrow in Fig.1, and the ends of the spring wipers 52 engage the upper edges of the cakes 46 and if the cakes are inclined backwardly instead of for.- wardly, the spring wiper will move the upper edges of the cakes forwardly and maintain them in this position until the cakes are ready to be removed from the conveyer belts 5.

I willnow proceed to describe the manner in which a section of the line of articles is moved from the conveyer-belts 5. This means is perhaps best illustrated in Figs. '7, 8, 9, 10, and 11. The driving means for the mechanisms shown in Figs. '7 to 11 inclusive, are shown in Figs. 4, 5,

and 6, and will be described in connection with the description of Figs. 7 to 11.

The articles which are to be removed from the conveyer belts 5 are carried into pockets provided in the ends of the arms 53 which form a turret indicated generally by the reference numeral 54 and carried by a shaft 55 to which it is rigidly secured. Each of the pockets at the ends of the arms 53 comprises a pair of spaced projections 56 to which are secured the pins 51. Plates 58 slidable on the pins 51 are spring-pressed toward each other by means of the springs 58 surrounding the pins 51 and'abutting the collars 68. The lower edges of the plates are bent inwardly as at 6|. See particularly Fig. 11. The plates 58 form the opposite bottom edges of the pocket and the projections 58 on the arms 53 form the pocket are the abutment plates62, which are rigidly secured to the projections 58 or arm 53. At the other end of the pocket are a pair of fingers 88 which are adapted to be drawn toward the opposite end of the pocket by means of the springs 64. The cakes are moved into the pocket by means which I will presently describe, from the underside of the turret, and in order that the cakes will move into the pocket, the springbelts 5 as is clearly illustrated in Fig. 11. The rods 68 are .guided by the brackets 51, and are connected-by means of the tie bar 68 at their lower- .out injury to those portions of the gear teeth same direction to impart rotation to the shaft 22 most ends. -A link 68 pivoted at I8 to the tie bar 68 is also pivotally connected at to the outer end of an arm "I2 pivoted on the shaft 13. The arm 12 carries an extension 14 having a roller on the outer end thereof which roller is 5 adapted to travel in a cam groove in the left hand faceof the double cam 15 shown particularly in Figs. 5 and 6. This cam 15 is secured to the drive shaft 34 and when the shaft 34 is rotated, the' arm I2 is oscillated to cause vertical movem ment of the plunger 65.

The plunger is provided with a lever 16 pivoted at 11, the upper surface of the lever being substantially in the same horizontal plane as the upper surface of the plunger 655A spring 18 15 normally urges the upper end of the lever away. from the plunger. A roller 18 rotatably mounted on the bracket support I8 is adapted to engage the lower beveled surface 88 of the lever 16 when the lever 16 is moved downwardly a sufficient amount for this purpose,so that when the plunger is in its lowermost position the lever is sub.- stantially vertical as is best illustrated in Fig. 7. However, when the plunger moves upwardly so that the roller 18 can no longer act on the lever IS, the upper end of the lever will be moved outwardly by the spring 18 as is best illustrated in Fig. 8.

8| and to the rear end of the shaft 8| is secured a gear sector 82 having theextension 83 connected by,means of a link 84 to an arm 85' pivoted on the shaft 13 (see Figs. 4, 5 and 6) and this arm 85 carries a roller 86 which travels within a suitable cam groove in the'cam 81, shown in Figs. 5 and 6. As the cam 81 rotates, the section 82 is caused to oscillate in the manner which has Just been described. A gear 81' is rotatably mounted on the shaft 22; and meshes with the teeth on' the gear sector 82. An arm 88 secured to the shaft 22, has a pawl 88 pivotally supported thereon at 80, and a spring 8| normally urges the pawl in a clockwise direction as viewed in Fig. 10. As the gear section shown in 82 rocks in a clockwise direction as viewed in Fig. 10, the gear 81' is caused to rotate in a counter-clockwise direction. The gear 81 is wider than the gear sector 82 as is best illustrated in Fig.,5, so that the teeth of thegear may be engaged by the pawl 88 withthereon which engage the gear teeth on the gear. sector 82. As the gear 81' rotates in a counterclockwise direction, the arm 88 is rotated in that in a counter-clockwise direction as viewed in Fig. 10, or in a clockwise direction as viewed in Figs. 7, 8, and 9. Since the pulley 2| is secured tothe shaft 22, the pulley as well as the belts 5 will move in the direction of the arrows shown in Figs. 7, 8,

and. 9. Of course the intermittent movement of the belt carries successive sections of the line 01'- articles supported on the conveyer be'lts 5 above the plunger 65 so that the plunger 55 when raised vertically, will move a sectionof the line 55 of articles into the pockets formed by the plates 6|, 62 and fingers 63.

A stripper plate 88' is pivotally connected to the links and 8| which-in turn are pivoted to the guide 2 at 82 and 83 respectively. See' Figs. 7 and 10. A spring 84 connected to a pin' i on the guide 2 and to a book 85 on the link 8| is adapted to normally draw the'link 8| against the stop 81 while permitting movement of the link 8| away from the stop under the influence 'u' The bearing support l8 rotatably carries a shaft 30 of a cam mechanism which will be described presently. The link 9| carries an extension 98 having the upper beveled surface 99. The upper end of the extension 98 lies in the path of movement of the projections I00 and IN on the gear 40. As the gear 40 rotates, the projections I00 and IM are successively brought into engagement with the extension 98, and cause' the stripper plate 89' to bemoved to the left against the actionof the spring 94.

A shaft I02 (see particularly Figs. '7, 8, 10, and 11) has the arm I03 rockably mounted thereon and this arm has a horizontally extending projection I04 extending through a slot I05 in the 1'6'-' guide 2, the slot I05 being arcuate with the center of the arcuate portion at the axis of the shaft I02. The horizontally extending projection carries "the fingers I06 thereon, these fingers being arranged I in staggered relation as best illustrated in Fig. 11, and being arranged between the guides I and 2. A link I01 pivoted to the arm I03 at I08 is also pivoted at I09 (see Fig. 6) to an arm IIO rockably mounted on the shaft I3 and having a cam I roller III thereon which travels in a suitable 2 cam groove in the cam H2 (see Figs. 5 and 6).

As the cam I I2 rotates with the shaft 34, the arm I I0 oscillates and causes an oscillating movement to be imparted to the arm I03 through the intera mediary of the link I01. This rocking movement of the arm I03 alternately positions the fingers I06 in the positions shown in Figs. land Fig. 9'.

'The operation of the means for removing uc- M) tions of the line of articles on the conveyer belts 5 is as follows: G

' As, the plunger 65 begins its vertical movement upward, the pin I00 on the gear strikes the upper end of the extension 98 and rocks the stripper-plate slightly to the left or rather moves (0% the stripper plate 89 to the left for a short interval of time so that as the plunger engages a group of cakes on the conveyer belt and moves the same upward, the stripper plate 69' will not be in the way of the endmost cakes, but as soon as the cakes have begun their upward movement, the stripper plate is advanced by the spring 94 to bring the end of the stripper plate against the endmost cake of the section of the line of cakes j being removed and to press them against the fingers I06 and against the plates 62, while they are being moved into the recess in the arm 53 of the turret. After the plunger has moved upwardly a short distance carrying with it a group of cakes, the endof the lever 16 moves out of en- 'gagement with the roller I9 and the spring I8 causes the upper end of the lever to move into the position illustratedin Fig. 8 although this movement occurs at a. point considerably below the point at which the plunger is shown in Fig. 8. This movement of the lever I6 causes an extension of the supporting surface of the plunger so that the endmost cake will not be dropped off the plunger after the plunger begins its upward movement.

' As'is quite readily seen in Fig. 8, the plunger moves to a position above the lowersurface of the stripper plate 83" and therefore it is necessary that the stripper plate be again moved to the .left to make room for the upper end of the lever 16 as otherwise the end of the lever I6 would strike the'underside of the stripper plate 09 and cause a jam, and no doubt a destruction of apart of the mechanism. This movement of the stripper I plate is effected by the projection IN on the gear 46. Asia apparent from an inspection of Figs. 7

and 8, the projection MI is longer in a peripheral direction than the projection I00 and conse-' quently, will hold the stripper plate to the left'for a longer period of time than will the projection I00. At substantially the same time that the F6 cakes are positioned entirely within the recess in the arm 53, the projection I 0I moves out of engagement with the extension 98 which is connected to the stripper plate as will be seen from an inspection of Fig. 8, and the plunger 65 begins its 10 downward movement.

With the arrangement which has just been described, it is clear that the cakes are moved vertically without the danger of having a jam and that the cakes are constantly pressed together so 153 as to keep them in alinement and to prevent them from falling off the plunger 65. At the same time the plunger 65 is given an extended amount of surface for the purpose of preventing cakes from If cakes do drop off 80;.

into the next pocket in the turret.

In order that the cakes may be properly held in 30: abutting relation with each other and to insure that the same number of cakes are fed into the pocket each time, I provide a means which operates in conjunction with the conveyer belts 5 to firmly press the cakes which are fed by the conveyer belts 5, together. This means comprises the fingers I06 which are mounted on the horizontal extension I04 on the arm I03.

When the conveyer belts 5. begin their intermittent movement to the right in Figs. '7, 8, and 9, the 40 fingers I06 are in the positions illustrated in Fig. 9 and the cakes are then moved over onto the fingers I06 in the manner illustrated in Fig. 9, the foremost cakes falling more or less flatly on the conveyer belts 5 and then sliding upwardly 45.- alcng the fingers I06. It will be noticed from an inspection of Fig. 9, as well as Fig. 11, that the lowermost finger I06 is arranged between the-two conveyer belts 5 thereby insuring that the cakes will be properly engaged by the fingers At substantially the same time, or perhaps slightly be-' fore or after the time when the conveyer belts 5 complete their intermittent movement to the right, the link I01 causes the fingers I06 to be moved into the position shown in Fig. '7. The

conveyer belts 5 travel a distance which is somewhat greater than the length of the line of articles which is to be fed into the recess in the turret so that when the fingers I06 are brought into'the vertical position, the cakes are all moved back- 110' wardly a. slight amount thereby bringing the cakes into firm engagement with each other. After the fingers I06 are in their vertical positions,

' the plunger begins its upward movement in the" manner which has previously been described,- and 55; the cakes are 'fed into the pocket of the arm in the turret. It will be understood of course, that as soon as a section of the line of articles is moved into the turret and the plunger again is in shown in Fig. '7, the cakes will occupy a vertical I position. If the fingers I06 were kept in a vertical position as illustrated in Fig. 7, this would not be possible, and therefore it is practically necessary to move the fingers I06 into a position such as that shown in Fig. 9 in order that the cakes which have fallen, may be properly positioned again in a vertical position.

The plunger 65 not only acts as a means for,

moving the articles into the pockets of the turret,

but also acts as a means for counting the number of articles which are to be packaged in a single package thereby eliminating .a separate means- The plunger will always move ticles is positioned within the pocket 4 with the opposite edges of the wrapper beneath the projections H5. The wrappers are positioned in this manner by means of'mechanism which is disclosed in my application Serial No. 94,438 and while the pockets face to the left as viewed in Fig. 4. In other words, the extreme left. hand pocket shown in Fig. 4 is in the position occupied thereby when the wrapper is inserted therein. The means for inserting .the wrapper in-the pocket does not form a part of. the invention claimed in this application and has therefore been omitted as is also the means for wrapping the wrapper about the articles. When the pockets arrive at the position D shown in Figs. 4 and 5, they are in a position to receive. the articles from the turret 54 and means are provided for ejecting the article from the pockets in the turret as these pockets arrive at the position above the pocket at D. The turret rotates intermittently in a clockwise direction as viewed in Fig. 5. Each time the intermittent operating means actuates the turret, the turret is moved'one-fourth of a turn. The means for intermittently rotating the turret is best illustrated in Figs..4, 5, 6, and 12- and is constructed as follows:

To the shaft 55 which carries the turret is secured a 'disk II 6 having peripherally arranged notches I I1. A gear I I8 is rotatably mounted on the shaft 55, and has the arm I I9 secured thereto.

A pawl I20 pivoted atf=I2I to the arm H9 is pressed by means of the spring I22 in a clockwise direction so that the pawl is urged into engageof the cam as viewed in Fig. 6, or on the upper 1 face of the cam as viewed in Fig. 5. The cam 15 rocks the arm I24, an amount which will impart substantially a quarter turn to the gear H8 and consequently a quarter turn to the pawl I20 and to the disk H6 when the gear H8 is rotated in a clockwise direction. When the gear is rotated in a counterclockwise direction von the reverse movement of the rack. I23, the pawl I20 rides out of the notch I I I and over the outer surface of the disk I I6 into the next notch I I1. During this last movement it is necessary ,to prevent reverse rotation of the disk H6 and for this purpose I provide the detent I21 on the end of the arm I28 I which arm is pivoted at I29 and connected at I30 to a link I 3|. As is best illustrated in Fig. 6, the link I3I passes through the upper end of the arm I32 and is surrounded by a spring I33,.whichabuts the arm I32 and a collar I34 on the end 01' 5 'the link I3I. The arm I32 is rotatably mounted on the shaft I35 and has a projection I36 thereon carrying a cam roller I31 which operates in the cam groove I38 in \the cam I39 secured to the shaft I40. I As the shaft I40 rotates, the arm I32 is caused to oscillate. The arm I28 rotates in a clockwise direction as viewed in Fig. 12 out of the notch H1 in the disk I I6 as the disk is being moved by the pawl in a clockwise direction. Immediately after the arm I32 has been moved to the left as viewed in Fig. 6, the same is moved to the right and during this interval the pawl I has moved the disk H6 in a clockwise direction a sufflcient amount so that the detent, I21 is out of registra- 20 tion with the notches I I1. As a result, the detent I21 is brought into engagement with the periphery vof the disk H6, and rides thereon under the yielding tension of the spring I33 so that when the next notch H1 is presented to the detent I21, the same will drop into the recess and prevent reverse movement of. the disk H6 as the pawl begins its reverse or counter-clockwise movement as viewed in Fig. 12. The drive shaft I40 is driven by means of the bevel gears HI and I42 from the shaft I43, and a chain I 44 trained over the sprockets I45, and I 46 drives the cam shaft, 34 in unison with the shaft I40.

A considerable portion of the operating mechanism shown in my co-pending application Serial No. 94,438 of which this is a division, has been omitted in this application for the reason that the showing of the same is unnecessary to acornplete disclosure of the invention being claimed herein. Only suflicient of the ope'rating-rnechanism has been included to bring out the operation of the.,mechanism being claimed and to enable one skilled in the art'tomake'this inven- I tion.

When thePcakes have been'rotated into a position above the pocket at D, a plunger or ejector comes into operation, and this operates 'to' eject the articles onto the wrapper in the pocket at the position D. This means is perhaps best illustrated in Figs. 4, 5, 6, 13, and 14. A bracket I41 50 oted fingers I55, which are pivoted at I56 to the bracket and which-have cam operating heads I51 0 integral therewith, these cam operating heads being adapted to co-operatefiwith the projections I58 on the bearing I50, for a purpose which will appear presently.

As is best illustrated in Fig. 4, the rod I48 has 5 a collar I59 secured thereto, and this collar is connected by means of the'link I60 to an arm I6I secured to theshaft I62, rotatably mounted in the bracket I41. "The shaft I62 has a second arm I63 secured thereto and this arm is connected at I64 70 to a link I 65. The link I 65 is connected at I66 to an arm I61 rotatably mounted on the shaft 13,. The arm I61 carries a, roller I68 onthe end thereof, and this roller engages within a cam groove 4 in the cam I63. As the cam I69 rotates, the arm 15 movement when an arm of the turret is positioned over the pocket at D, and the plunger I54 first engages the upper edges of the series of articles which have been removed from the line of articles .on the conveyers 5. The bracket I5I continues its downward movement with the shaft I48, but

due to the fact that the plunger I54 rests on the upper edges of the cake 46, the plunger is held stationary while the bracket I 5| moves downplunger moves downwardly due to the fact that it is now engaged by the bracket I5I. The shaft I48 continues its downwardly movement until the section of cakes has been moved onto the wrapper in the pocket at D. It will therefore be seen that the cakes are moved out of the turret into the pocket at D without disturbing the assembled relation of thecakes 46. As the shaft I48 moves upwardly, the weight of the plunger I54 holds the cakes ,down in the pocket while the fingers I55 slide along the endmost cakes so that the cakes will not be drawn upwardly along with the shaft I48. The beveled surfaces on the lower ends of the projections I58 engage the cam heads I51 on the fingers I55 as the shaft I48 moves upward. As a result, the fingers I55 are again positio'ned as illustrated therefor in Fig. 14, and are ready to move the next section of cakes into the next succeeding pocket after the turret is rotated through its next quarter turn.

I will now describe briefly the operation of the entire conveying mechanism which has been described:

The cakes are fed into the trough 24 in any desired manner and are conveyed to the right bythe conveyer belt 3 between the guides I and 2. Any of the cakes which lie fiat on the conveyer 3 are ejected by the cam plate 41 through the recess 58, and the remaining cakes are carried over the cam plate 41 onto the conveyer belt 4 which is traveling at a greater rate of speed than the conveyer 3, and which tends to spread the cakes slightly more than they are spread on the conveyer tain the cakes in overlapping relation to each other.

In order toinsure that the cakes are inclined slightly forward rather than rearward,.the spring finger wipers 52 on the wheel 5I engage the upper edges of the cakes and incline them slightly'forward or at least into a substantially vertical position so that they will be in proper position when they reach the right hand extent of their travel with the conveyer belts 5.

conveyer belts 5, the fingers I66 are in the posi tion illustrated in Fig. 9, and the foremost cakes are moved onto the fingers I06. At substantially the same time that the conveyer belts 5 stop their movement toward the right, the fingers I86 are ,5 brought into the position illustrated in Fig. '7, and the plunger 65 thereafter moves upward to remove a section of the articles in line on the conveyers into the pockets formed in the ends on the arms 53 of the turret. During this movement, the upper end of the lever I6 moves outwardly to form an extended surface for the plunger 65 and the stripper plate 89' moves to the left both at the beginning of the upward movement of the plunger and also near the upper extremity of the plungers movement in order to make room for the upper end of the lever I6 as previously described.

The turret rotates intermittently to position 1 the articles above the pocket at D and by means of the mechanism which has been previously de- I scribed in detail. When the articles are in a position above the pocket at D, the shaft I48 moves downward and causes the cakes to be ejected from the pocket in the turret into the pocket In 25. the conveyer chain in which pockets the articles are wrapped by the mechanism which is fully described in my application Serial No. 94,438.

The conveyer chain which is formed of the v links H3 is mounted on sprockets and is intermittently operated to position successive pockets at the position D and in the manner fully described in my application Serial No. 94,438 of which this application is a division.
