ALFRED E. GRAVES, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO PACKAGE CONIEEC- TIONERY COMPANY, A CORPORATION OF MASSACHUSETTS.

ASSORTINCT- Application filed Marchl),

To all whom it may concern Be it known that I, ALFRED E. Graves, of Boston, in the county of Suffolk and State of hflassachusetts, have invented certain new and useful Improvements in Assorting-lilachines, of which the following is a specification, reference being. had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in machines for assorting sugar or candy wafers or other articles and for arranging the assorted articles in stacks which stacks are delivered to a suitable receiving apparatus for a further operation or for transference to another mechanism in which a further operation is or may be effected.

One object of this invention is to so construct a machine of this nature that stacks of articles may be progressively formed by the intermittent feeding of individual articles from different sources of supply and the stack so formed may be delivered without disarrangement of its constituent elements.

Another object of this invention is to so construct a machine of this nature that the stacks of fragile o-r brittle articles may be progressively formed without shock to the articles so that danger of breakage of the articles is practically eliminated.

Another object of the invention is to improve the construction and operation of the stack forming receptacles.

@ther objects of the invention will appear from the following description.

To attain theA objects ofthis invention recited above and others hereinafter more fully described the invention consists in such novel features of construction and combination of parts as are pointed out in the following description and recited in the claims.

Referring to the drawings. Figure 1, represents a plan elevation, with a portion indicated by dotted lines, of the upper portion of a machine embodying my invention. 2, represents a fragmentary sectional view, partly in elevation, on the line 22 of Fig. 1. Fig. 3, represents an enlarged fragmentary front elevation of a portion of the machine. Fig. 4, represents a fragmentary sectional view on the line 4-4 of Fig. 2

Like reference rcharacters designate corresponding parts throughout.

Secured to the tubular standard 10 which is provided with a base 11, is an annular bracket 12. Supported by the latter, near its periphery, are a plurality of vertical wafer containers or stack supports 13, each consisting of the base 14, rods 15 and the mouth piece 16. Said wafer containers are further supported by being secured near their upper ends, to the periphery of the annular bracket 17 fixed to the standard 10. The wafer fw may beplaced in each of said containers by passing them through its mouth piece 16 down between its rods 15, through the circular aperture 18 in its base 14 and down onto its feedingmechanism 19.` All of the latter are alike and each consists of the radially disposed supporting and guiding plate 2O secured to the top of the bracket 12 and extending through a slot in the base of one of said wafer containers, and the feeding plate 21 which is guided and supported by the plate 20. Pivoted at one end on the lug 22 fixed to the rear end of said feeding plate is the link 23 and the other end' of said link is pivoted on the lower end of the lever 24. The latter is pivoted at 25 on a bracket 26 xed to the standard 10 and the upper end of said lever engages the annular groove 27 in the sleeve 28 which is guided by the standto said sleeve by nuts on its ends. The low'er end of said rod is provided with the cam roll 32 which is held in engagement with the cani 33 on the shaft 34, hcareinafter described. by gravity, and by the action ot the helical spring 35. lt will be understood that the rotation of said shaft reciprocates the feeding plate 21 through the cam 33, cam roll 32, rod 30, cross bolt 31, sleeve 28, lever 24, link 23 and lug 22 and that said reciprocation will. be controlled by the contour of said cam. Said feeding plate is provided with the circular aperture 36 which, when said feeding plate is at the limit ot its inward movement, is directly in line with the waters w contained in the water container 13, and in said position, the waters drop by gravity so that the bottom one w will be contained in said aperture and be supported by the plate 20. The outward movement ot.' said feeding plate slides this wafer fw on the plate 20 until said feeding l plate has reached the limit ot said movement when said wafer drops by gravity through the aperture 37 in the plate 20. Normally, directly below each of the apertures 37 is the stack forming water delivery tube or receptacle 38, pivoted at 39 on the hanger 40 which is secured to the annular revolving bracket 41, hereinafter described. Said stack forming water delivery tubes or receptacles are spaced an equal distance apart around said revolving bracket. The latter is adapted to be intermittently rotated on ball bearing 43 between the lower end of its hub 44 and the collar 45 secured to the standard 1.0, by the pawl 46 which engages one ot the notches 47 spaced an equal distance apart on the under edge of the rim 48 on the bracket 41. (Figs. 7 and 8). Said pawl is pivoted on the outer end ot the arm 50 and is normally held in engagement with one of said notches by the spring 51. The inner end of said arm is supported on the hub 44 ot the bracket 41. (Fig. 2).

The arm 50 is oscillated by the link 52, one end of which is pivoted at 53 to said arm and the other end is pivoted to the lever 54. The latter is provided with a pivot pin 55 which engages a slot 55a in a standard 56 secured to the bed 58 ot the machine. The pivot end ot said lever is pressed upwardly so that the pivot pin normally engages the top of the slot 56 by the action of the expansion spring 57 which engages the under side of said pivot end and the lug 57a on said standard. The inner end of the horizontal arm of said lever is provided with the cam roll 60 which engages the groove in the cam 61 fixed to the shaft 34. The movement oi" the upper end of the vertical arm of the lever 54 is guided by the guide bar 61 lixed to the standard 62 projecting from the bed 58. Fixed to the shaft 34 is a cam 63 which is engaged by a cam roll on the inner end ot a idoine@c lever 64. The latter is pivoted at 65 on the standard 66 which is on the bed 58 and to the outer end of said lever is pivoted the lower end ot the link 67. r] `he upper end ot the latter is pivoted to the lower end ot a lock bolt 68 which passes through and is guided by a casing 69 screwed to a plate 70 secured to the standard 62. The upper end ot said lock bolt, by the action of the spring 7l, which is attached at one end to the lever 64 and at the other end to the standard 62, normally engages one of the shaped notches 72 spaced an equal distance apart, around the under side ot the rim 48 on the bracket 41.

It will be understood that the lock bolt 68 is moved out of engagement with the notch 92 by the workingl contour of the cam 63 through its cam roll, lever 64 and link 67. Immediately after the lock bolt 68 is moved out of engagement with the notch 72 the bracket 41 is rotated in the direction of the arrow shown in Fig. 8 by the pawl 46 through the arm 50, link 52, lever 54, cam roll 60 and cam 61, until the next notch 72 has been moved into the path of said lock bolt, when the latter is allowed by the cam 63 to be moved into said notch by the action of the spring 71. Simultaneously with the completion of the last movement, the pawl 46 comes to rest and on the return movement disengages from the notch 47 against the action ot the spring 51 and at the limit of the return movement it snaps into the next notch. The lateral movement of said pawl .is controlled by the cam 61. It is to be understood that the movements ot the bracket 41 are equal and that after each movement it is rigidly held stationary. The outer end of the arm 50 may be supported by the pawl 46 bearing on the supporting bar 74 which is formed on the plate 70.

Projecting from the bottom ot the stack forming receptacle 38 is the hanger 76 and extending through the latter and through said bottom is the plunger 77 consisting of the head 78 made of felt or other resilient material and the elongated rod 79 provided with the reduced portion 80 near its end which forms shoulders 81. Supporting a majority oit' said plunger-s is the annular inclined track 77a, on the highest end 77b of which is pivoted the guiding lever 78a at 78". (Figs. 1, 2, 13 and 14.) The inner end of said lever is normally sustained in the position shown in Fig. 13 by the spring 7 8C. Secured to the hanger 76 is the bracket 82 provided with the stud 83 which is adapted to be received by the elbow slot 84 in the lever 85, the lower end ot which is pivoted on a bracket 86 projecting from the bed 58 ot the machine. Pivoted on said lever is one end of the link 87, the other end of which is pivoted on the lever 88 which is pivoted on the bracket 89 on the bed of the machine.

Said lever is provided with the cam roll 90 which engages the groove in the barrel cam 91 on the shaft 34. Nhen the stud 83 has been moved into the path of the elbow slot 84 in the lever 85, in the manner hereinafter described, the latter is swung inwardly, causing said slot to engage the stud 83 thereby swinging said receptacle 38 on its pivot 39 from its normally vertical position to a horizontal position.

Fixed to the bracket 12 is the guiding plate 95 which is adapted to receive slots in the end of said receptacle 38 during the latters oscillating movementand it is cut away at 96 to allow said receiving' tube to be moved about the standard 10. Near the completion of the downward oscillation of saidreceptacle 38, the end 80 of the plunger rod 79 engages a recessed lug 97 on the carriage 98. The latter is supported and guided by a bar99 supported by the standard 10 and on its under edge is the rack 1.00 which meshes withthe gear segment 10-1. The latter is pivoted on the bracket 102 and is oscillated by the arm 103, lilik 104, lever 105 pivoted on the bracket 106, the cam roll 107 on said lever engaging the groove in the barrel cam 108 on the shaft 34 with the assistance of the spring 109 which is connected at one end to the lever 105 and at the other end to the bracket 102. After the end of the rod 79 engages the recess in the lug 97 the carriage 98 is moved forward by the segment 101 and said lug engages the shoulder 81, thereby causing said plunger to move forward with said carriage.

When a receptacle 38 is about to receive its first wafer its plunger is supported by the end 77b of the track 77a, so that the head of said plunger is slightly below the open end of said receptacle and as the wafers drop into said receptacle said plunger is allowed to gradually drop b v the incline of said track and when said receptacle is filled its plunger slides from the lower end 77c of said track. The distance thatsaid plunger drops while sliding on said track from one feeding mechanism 19 to another is equal to the thickness of a wafer. As the head of a plunger supports the wafers after they have entered a receptacle the gradual drop of said plunger will equalize and minimize the distance that said wafers drop from a feeding mechanism 19 into said receptacle. Vhen a plunger reaches the lever 78 it swings said lever in the direction of the arrow shown in Fig. 13 which allows said receptacle to be swung into its horizontal position and its plunger forced forward, as hereinbefore described. During the latter movement of said receptacle its plunger disengages from said lever which allows the latter to be returned to its initial position by the spring 78C. The carriage 98 is moved back by the same mechanism as accomplished its forward movement and during the first part of said back movement it carries said plunger with it until the head of said plunger has passed the end of the guiding plate 95 when said plunger is disengaged from said carriage and is swung downwardly by the lever 85. rJhe inner arm of the lever 78a is of suflicient length to be engaged by the end of Said plunger during the latter movement of said delivery tube and issuitably curved to sustain said plunger in the same relative position to said receptacle as it was when disengaged from said carriage. ris said lever is in effec-t a continuation of the highest end of said track, said plunger will ride onto said track while said receptacle is moving` to receive its first wafer. The rib 77d, on said track and the stops 38a fixed to the bracket 41 sustain said receptacles and plungers in a substantially vertical position while the latter rides on said track.

1Vhen the receptacle 38 is in a horizontal position its open end extends slightly into and is in line with the semi-cylindrical. delivery tray 111. The latter consists of two elongated leaves 112 and 113 with their outer edges secured to rods 114 and 115, respectively, which are pivoted in the end plates 116 and 117. The end plate 117 is recessed to allow a free passage from said receptacle 38 into said tray and is secured to the cross bar 118 which is fixed to two standards 119 projecting from the bed of the machine. The leaves 112 and 113 are held normally, closed by leaf springs 120 fixed to the cross bar 118 and bearing against the ends of arms 121 on the rear ends of the rods 114 and 115. (Figs. 3, 5 and 6.)

Fixed at one end to the bracket 122 projecting from the end plate 117 is the stationary rod 123 and the other end of said rod is fixed to the bracket 124 projecting from the end plate 116. Mounted and adapted to slide on the rod 123 is a sleeve 125, provided with a bracket 126 which extends into the tray 111. On the inner end of said bracket is the pad 127 and the vertical plate 128 having the inclined edge 129. The pad 127 is moved toward the receiving end of the tray 111 by the weight 132 conneoted by the cord 133 to the stud 134 projecting from the sleeve 125. Said cord passes over a pulley 135 on the bracket 136 projecting from the cross bar 118. Secured to one of the bars 137, which connect the end plates 116 and 117, is the vertical frame 138 provided with lugs 139. Extending thro-ugh and guided by said lugs are rods 140, the lower ends of which carry the discharge member 141 and the upper ends are secured to the cross bar 142 and to the upper eX- tremitiesof the wafer guiding plates 143 and 144. The discharge member 141 is reciprocated by the link 145 connecting the cross bar 142 to the arm 146 fixed tothe shaft 147 which is journaled in brackets 148 projecting from the frame 138. On the rear end of said shaft is secured the arm 149 con nected by the link 15() to the lever 151. The latter is pivoted on the bracket 152 projecting from the bed plate 50, and is provided with the cam roll 153 which is held in engagement with the cam 154 on the shaft 34, by the spring (Figs. 2, 3, 4 and 12.)

The shaft 34 is journaled in bearings 157 and may be driven by any suitable driving and clutching means, e. g., in Fig. 2 is shown the continually rotating gear 158 loosely mounted on the rear end of said shaft and provided with sockets 159 which are adapted to receive the stud 160 projecting from the arm 161 pivoted on said shaft. The stud 160 is thrown into engagement with one of the sockets 159, thereby forcing said shaft to rotate with said gear, by the spring 162. The lever 163 is pivoted on the base 11 and its lower arm is connected by the rod 164 to the foot lever 165. The upper end of the lever 163 is provided with an inclined surface 166 which is normally held in the path of the end of the arm 161 by the spring 167. When the end of the arm 161 strikes the inclined surface 166 it is thrown out of engagement with the gear 153 and rides down on said inclined surface until it engages the stop 166 which prevents further rotation oi' said shaft. It is to be understood that in order to operate the machine the end of the lever 163 must be thrown out of the path or the end of the arm 161 and this is accomplished through the link 164 and foot lever 165.

As all the feeding mechanisms 19 operate simultaneously, it is advisable to first load with wafers in the manner hereinbei'ore described, the wafer container 13a which deposits the first wafer in the receptacle 3S and then after the feeding devices have operated once, to load the next wafer container 13" and so on, so that when each receptacle 38 reaches the delivery tray 111 a wafer has been deposited therein by each delivery mechanism from its wafer container or stack holder. (Fig. 1). It is to be understood that the number of wafers deposited in each receptacle will depend upon the number ot wafer containers that are loaded. The drawings show four more receptacles than vater containers but it is obvious that only one more receptacle than wafer container is necessary. Then a delivery tube has received a wafer from each of said wafer containers and has reached the delivery tray 111 it is swung down into its horizontal position and the forward movement of the plunger 77 slides the stack of wafers from said delivery tube into said delivery tray against the pad 127 which sustains each wafer in an upright position. At the completion of the forward stroke of said plunger its head extends slightly beyond the vertical plane of the guiding plate 144 and the inclined surface 29 of the plate 28 is in a position to be engaged by the guiding plate 143. Then said guiding plates and the discharge member 141 move downwardly, the guiding plate 143 engaging the inclined surface 29 which moves the pad 127 suificiently away from said wafers to allow said guiding plate to pass between said pad and said wafers and the guiding plate 144 forces the head 78 sufiiciently away from said wafers to allow said guiding plate to pass between said wafers and said head. The plunger 77 is then moved back and the delivery tube is swung up into its vertical position. During the latter movement the discharge member engages the column of wafers and Forces them to open and to pass down between the leaves 112 and 113 of the delivery tray 111 against the action or' the springs 120. (Fig. 4). The guiding plates 143 and 144, as they move with the delivery member 141, prevent lateral movement of said wafers. On the table 170 secured to the standard 119 may be supported a suitable receptacle for receiving the wafers. In order that the discharge member 141 will not injure the waters the dwell 171 on the contour ci the cam 154 retards the downward movement of said discharge member when about to engage said wafers.y After the latter operation, the dis charge mechanisms return to their initial positions ready to receive and discharge the column of wafers from the next receiving tube.

1f the bracket 41 is forced to rotate after a wafer has become accidentally dislodged or a part of the machine has got out of order, serious damage may result and for this reason it is desirable not to rotate said bracket after it is thus hindered. In view of this, the pivot pin 55, on the lever 54, the slot in the standard 56 and the spring 57, hereinbeiore described are provided, so that when more than the usual amount of power is required to rotate the bracket 41, the link 52 will not be moved longitudinally, as is required to rotate the bracket 41, but will be swung downwardly on its pivot 175, as the pivot end of the lever 54 will move downwardly by overcoming the expansion of the spring 57. (Fig. 8.)
