Specification of Letters Patent.

Patented Oct. 29, 1918.

Application filed April 21, 1915. Serial No. 22,830.

To ail whom it may concern:

Be it known that I, Ennsr FREnERm HENRY ENNA, a subject of the King of Denmark, residing at Copenhagen, Denmark, have invented certain. Improvements in Sorting and Splitting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to splitting and sorting machines and is herein illustrated in connection with a machine for splitting and sorting soles, counters and similar articles.

One feature of the invention comprises a machine having mechanism for splitting and sorting a series of blanks. and automatic means responsive to the thickness of av predetermined locality in each blank fed to the machine for controlling the operation of said mechanisms. With this construction the blanks may be fed one by one to the machine and are thereupon. first automatically split or evened in accordance with their respective thicknesses and then similarly sorted.

This and other features of the invention including certain details of construction and combinations of parts will b described in connection with an illustrative machine and pointed out in the appended claims.

Referring now to t e accompanying drawings,

In United States patent to McKay No. 156,489 a sorting and printing machine is shown comprising a lower feed. roll the diameter of which is uniform and an upper feed roll having portions the diameters of which regularly decrease so as to form a plurality of steps. In the rear of these rolls is the usual splitting knife, and in the rear of theknife are a plurality of receptacles, one for each step of the upper feed roll in which the skived blanks are received. The operator, by inspecting each b1ank estimates its thickness and feeds it to the step which he believes to be the proper one.

For convenience the invention is illustrated in connection with a machine of this general type, but in the improved machine the feeding of the blank to theproper step is accomplished automatically and is con trolled by the thickness of the blank in a predetermined locality.

Referring now to Figs. 1 to 6 and more particularly to Figs. 1 and 2, there is shown a machine the splitting mechanism proper of which is like that of the machine illustrated in United States patent to Nash No. 894,850 except that the upper feed roll is provided with a plurality of steps (in the present case two) so that the machine is adapted to handle two different thicknesses of blanks. In Fig. 2 the steps of the upper roll are indicated at 2 andll, the lower roll at 6 and the knife at 8, said rolls being driven continuously as in the patented machine through suitable 'gearing from a shaft 12 provided with fast and loose pulleys l8 and 22. A hand wheel 24' isprovided by the turning of which the bearings of the upper roll may be adjustedvertically and at the same time a pointer 26 caused to travel over a scale 28. All this mechanism is substantially identical with that shown in the Nash patent and will not be described in detail.

Fastenedto the front of the machine is a bracket 30 carrying two horizontal tracks 32 upon which run four rollers 3a of a carriage 36. Mounted in this carriage are two feed rolls 38 and 40 to which the blanks to be split and sorted are presented. The lower feed roll is idle while the upper feed roll is fast to a shaft 42 said shaft being splined to a sprocket wheel 54 so as to be capable of horizontal movement with the carriage 36. In the operation of the machine a blank is fed to these rolls 38 and 40 whereupon the lower roll 40 is depressed to an extent dependent upon the thickness of the blank. The depression of the lower roll first throws into operation a one-revolution clutch which is connected with a cylindrical cam 44, and then swings a guiding arm 346 so as to cause a roll near its lower end to travel either in the right hand branch 48 or the left hand branch 46 of a cam track. The carriage 30 is thereby moved horizontally either to the right or to the left depending upon the thickness of the blank so as to present the blank either to the step 2 or the step 4 of the upper roll of the splitting mechanism.

The cam 44 is fast to a shaft 348 which carries loosely at one end a sprocket wheel 50. Thi sprocket wheel is driven by a chain which passes around said sprocket wheel over the sprocket wheel 54 and around a sprocket wheel 156 fast to the shaft of the stepped roll of the splitting mechanism. The sprocket wheel 50 is fast to a sleeve 56 which is normally loose on the shaft but may be clutched to said shaft by a Sliding clutch member 58 having teeth which engage similar teeth on the end of the sleeve 56. A spring 60 (see Fig. 6) normally holds the clutch member 58 to the right, as shown, a socket in the rear of said member receiving a projection 62 on an adjustable but normally stationary collar 64 having a handle 66 provided with an arcuate slot 68 (see Fig. 3) to receive a clamping screw 70. The details of this clutch form no part of the resent invention and will not be described urthcr. It will be understood. however, that when the clutch member 58 has been moved to the left and engaged by the teeth on the end of the rotating sleeve 56 the shaft 348 to which the clutch member is keyed will be given one revolution whereupon the projection 62 on the stationary collar 64 will be opposite to the socket in the end of the clutch member, and said clutch member will be returned to inoperative position, as shown in the drawings, by the spring 60. By adjusting the collar 64 the timing of the clutch, and consequently of the cam 44 may be varied.

Referring now more particularly to Fig. 4 the mechanism for moving the member 58 to the left and thereby throwing in the clutch will be described. An actuating arm 68 is fast to one end of a rock shaft 70 to the other end of which is fast an arm 72 to the upper end of which is pivoted a link 74 yieldingly connected by a spring 76 with a bell-crank lever 78 pivoted at 80 to the bracket 30 which is rigid with the frame of the machine. The point of an adjustable screw 84, which is threaded through one arm of the bell crank lever, contacts with a pro- 'ection 86 on a bar 88 which connects the earings of the lower feed roll 40 so that when said roll is depressed by the entrance of a blank between the rolls 38 and 40 the clutch is thrown in and the cam 44 begins its rotation. As has been explained the carriage 36 moves to the right or to the left. The bar 88 moves with it so that the projection 86 is presently out of register with the screw 84, and the clutch may be thrown out at the end of one revolution.

Referring now more particularly to Figs. 1, 2 and 4. the mechanism by which the cam 44 moves the carriage 36 to the right or left in accordance with the thickness of the stock will be described. The bearings 200 of the upper feed roll 38 are rigid with the carriage 36 while those of the lower feed roll 40 are vertically slidable in ways in said carriage, being formed at their lower ends as wedges 90. Cotiperating with and supporting these hearings are two complementary wedges 92 fast to a bar 94 which is horizontally slidable in the carriage 36, said bar be- 9 ing continually urged to the right by a coiled spring 96 which at one end presses against a boss on the carriage and at the other against a nut 98 on the end of said bar 94. The effect of the spring is thus to force the lower feed roll 40 upwardly at all times, this upward movement being limited. when no stock is in the machine by stop screws 100 threaded into the bearings of the upper roll 38, the heads of which contact with the upper faces of the bearings of the lower roll. The lever 346 is pivoted to the carriage 36 at 104 (see Figs. 1 and 2) and is connected with the bar 94 by a pivot 106 which projects into a slot in a block 214, said block being mounted on a screw 216 so as in be adjustable along said bar if desired. The arm 46 has at its lower end a yoke which enibraces a small stud 108 set in the upper part of a small controlling arm 110. Thi controlling arm is pivoted at 112 to a cross bar of the carriage 36 and has fastened to its extreme outer end a pointed deflector 114 which is adapted to be engaged on one side or the other by a similar deflector 116 (see Fig. 5) screwed to the cam 44 at one junction of the branch cam tracks 46 and 48. A roller 120 which runs in the track of the cam 44 is rotatably mounted at the end of the pivot 112. When, therefore, a piece of stock is fed between the rolls 38 and 40 the lower roll will be depressed and the bar 94 moved to the left a distance dependent upon the thickness of the piece of stock. This will swing the lower part of the lever 46 to the 1 whereby the amount of of are rod is limited. Supporting the rod returns to its left about the pivot 104 thereby carrying the stud 108 to the left and swinging the deflector 114 to the right about its pivot 112. The position of this deflector 114 at. the time it is passed by the cooperating deflector 116 on the cam 44 will thus determine in which of the branches 46, 48 the roller 120 will travel. Since the roller is mounted on the pivot 112 which is fast to the carriage 36, said carriage will be moved to the right or the left according as the roller 120 travels in the branch 48 or 46. The initial position of the arm 346 and consequently of the deflector 114 may be varied by turning the screw 216.

In order to revent the operator from feeding a second piece of stock to the machine before the first one is well out of the way a gate 122 (Figs. 1 and 3) is fast to a rod 126 to one end of which is fast a crank 128 said crank being pivoted at its outer end to a rod 130 vertically slidable through a bracket 132 on the carriage 36. Two spaced. pins 134 are driven through the rod 130 vertical movement from below is an arm 136 fast to one end of a rock shaft 138 to the other end of which is fast a second arm 140 the lower end of which contacts with an enlarged portion of the clutch member 58 so that when said clutch member is moved to the right, as viewed in Fig. 1, the arm 136 will be swung upwardly and the gate 122 opened. A

w spring 142 tends always to urge the rock shaft 138 to turn in a clockwise direction, as viewed in Fig. 1, and thereby to keep the arm 140 in contact with the enlarged portion of the clutch member 58. hen now in the operation of the machine a piece of stock is fed to the rolls 38 and 40 and the carriage 36 moves to the right or left the rod 130 is moved out of register with the upper .end of the arm 136 whereupon said arm drops until the edge of the gate 122 rests upon the upper face of the stock. And presently when the rear end of the stock passes from beneath the gatesaid gate falls until the upper one of the pins 134 contacts with the bracket 132. The gate is then completely closed and remains closed until the carriage normal central position and the rod 130 is once more above the upper end of the arm 136. Them when the clutch member 58 moves to the rightysaid gate is raised or opened to permit the presentation of another piece of stock.

In order to guide a piece of stock, such for example asa counter, to the rolls 38 and 40 guides 144 which project up through a slot in a shelf 146 are threaded upon a right and left threaded screw 148.

Referring now to Fig. 2 there is attached to the rear of the machine in any suitable manner a chute 150 having in its center a toregister with the junction of structed that the movement partition 152 said partition being arranged the steps 2 and 4 of the upper roll of the splitting mechanism so that the pieces of stock which are fed to these steps are sorted into two collections and may be received in two properly located receptacles.

The operation of the machine is as follows:

With the parts of the machine in the positions shown in Figs. 1 to 4 inclusive of the drawings the forward end of a piece of stock such the gate 122 and presented to the feed rolls or measuring rolls 38, 40. The lower roll 40 is thereby depressed and through the mechanism shown in Fig. 4 throws in the onerevolution clutch which starts the rotation of the cam 44. At the same time the bar 94 is forced to the left whereby the deflector 114 is swung to the right. If the counter has thick and thin localities the deflector will swing to the left or right until the rotation of the cam 44 brings the cooperating deflector 116 into position to force the deflector to the right or left as the case may be.

It should be noted that the thickness of the counter at the locality which is gripped by the rolls 38 and 40 when the deflectors 114 and 116 come into register with each other is the thickness in accordance with which the counter will be split and sorted, and that the locality in the counter which will be gripped at this time may be predetermined by adjusting the handle 66 of the collar 64 so as to vary the timing of the onerevolution clutch. In other words the position in which the cam 44 c mes to-rest de termines the locality of the counter in accordance with the thickness of which the counter will be split and sorted.

The throwingin of the one-revolution clutch has permitted the gate 122 to fall until it rests upon the counter; and when the rear end of the counter passes from beneath it the gate will fall completely. Meantime the roll 120 has been deflected into one or the other of the branch tracks 46. 48 and the carriage 36 is moving to the right or the left. The branch tracks 46. 48 are so conof the carriage toward its extreme position to right or left. takes place quickly, after which there is a dwell during which said carriage is held in its extreme position. While the carriage is so held. the counter is delivered to one or the other step of the roll of the splitting mechanism. The carriage then returns to its normal middle position, and as the clutch member is forced to the right-to disconnect the clutch the gate 122is raised.

Referring now to Figs, 7 to 10 inclusive a modified form of machine is shown.

Mounted in hearings in the frame of the machine are two feed rolls 7 and 9. the latter as a counter is pushed beneath usual to pass in a sliding carriage 31 wing of which is provided with two steps or portions of different diameter 11 and 13, said rolls being driven through gears 14 and 16 from gears and 17, the gear 15 being fast to the shaft of the driving pulley 19. The mounting of the feed rolls 7 and 9, not shown, is the same as that of the ordinary leather splitting machine, such for example as is shown in United States patent to Nash No. 894,850 referred to above. The usual knife 21 is located at the rear of the feed rolls, the waste material being arranged as beneath the knife while the finished blank passes above it and into suitable receptacles 10 which are similar to those of the McKay patent referred to above.

Meshing with the gear 14 is a gear 23 which in turn meshes with a gear 25 formed on a shaft 27 whi -h carries the measuring roll 29. In order to permit bodily movement of the shaft 27 longitudinally d its axis the gear 25 is elongated so that it will always remain in mesh with the gear 23. The shaft 27 is mounted in bearings 39, 41

provided with rollers 33, one of which is shown in Figs. 7 and- 9, which run on tracks formed on portions of the frame of the machine. The uaper part of the sliding carriage 31 is in the orm of a plate having a flat under surface 37 between which and the measuring roll 29 each blank is fed, this feeding, as will presently appear, serving to depress the roll 29 and through appropriate mechanism to move the carriage 31, together with the roll 29, either to the right or to the left as viewed in Fig. 8.

Referring now to this figure, the bearings 39 and 41 of the shaft 27 are vertically slidable in the carriage 31 and are connected with each other by a bridge 43, each bearing being formed at its lower portion with a wedge 45. These bearings are supported by complemental wedges 47 connected by a bar 49, the latter wedges 47 being slidable in a direction parallel to the shaft 27 upon bearings in the sliding frame 31. The bar 49 has at its end a downwardly extending portion 149 through which passes a rod 51 the right hand end of which is connected with the carriage 31 by a spring 53, said spring acting to pull the bar 49 to the right and normally to maintain the measuring roll 29 in its uppermost position. The tension of the spring 53 may be varied by turnin a nut 52 which is threaded on the en of the rod 51. Rotatably mounted in the lower part of the bridge 43 is a short shaft 55 to one end of which is fast a controlling arm 57 and to the other end a short arm 59, said short arm being connected by means of a bar 61 and a threaded bolt 63 with the'downwardly extending portion 149. The connection between the threaded bolt 63 and the extension 149 comprises a headed sleeve 65,

a spring 67 bearing against the extension 149 and a thumb nut 69 by which the tension of the spring may be varied. The purpose of this spring connection is to prevent possible breakage of the parts during a time when the controlling arm 57 is ocked against movement. This controlling arm, by its position at a given point in the cycle of operation of the mechanism, determines whether the sliding carriage 31 shall be moved to the right or to the left.

The movement of the carriage is effected by the engagement of one or the other of two pawls with one or the other of two worm gears. The shaft 27 has formed, one on each side of the measuring roll 29, worm gears 71, 73 with which the pawls 171 and 173 are adapted to cotiperate, each pawl having a diagonally disposed fin 175, 177 adapted to engage its corresponding worm gear. The teeth of the worm gears extend in opposite directions, and consequently only one pawl at a time must be in engagement with its correspondin gear. These pawls are pivoted on a rod 75 see Fig. 7) and are arranged to be raised y slides 77, 79 (see Fig. 8) which are fitted into dovetailed grooves (see Fig. 10) in the bridge 43. Carried by these slides are pivots 81, 82 which extend through slots in the opposite ends of a lever 83, said lever being pivoted at its center upon a stud 85. This stud is screwed through a slide 87 which is also mounted in a dovetailed slot in the bridge 43 (see Fig. 10); and is carried by an upward extension of a cross beam 89. (/onsequently, when the cross beam is raised the stud 85, the slide 87 and the lever 83 will be raised with it. If now the slide 77, for example, and its stud 81 are held stationary, the slide 79 will be raised through its connection with lever 83 a distance twice as great as that through which the cross beam 89 moves. In order to hold one or the other slide from movement, said slides carry segments 91 and 93 one or the other of which will be engaged by the controlling arm 57 when the crossbeam 89 starts its upward movement. This arm is provided with a hook or projection which extends into the path of the segments; and in order to prevent the hook from holding both segments at once, as well as to prevent the segments from simultaneously passin the hook, the hook is provided with an inc ined projection 95 on its left side (see Fig. 8), and the right hand segment 91 is provided with an inclined face 97. When now the cross beam 89 is moved upwardly by mechanism presently to be described one segment or the other will be held from movement by the arm 57 with the result that the slide 77 or 79 to which the other segment is fast will raise its pawl 171 or 173 into mesh with the worm gear 71 or 73. The cross beam 89 is adapted to be raised by two rods 99, 101 having at their upward ends racks 102 (one of which is shown in Fig. 9) which engage at the proper time gears 193 and 105 fast to the shaft 27.

Inasmuch as these two sets of rods, racks and gears are identical, only one will be described in detail. Referring particularly to iFi-gi 9, the rod 99, having. the rack 102 and the cut away portion 10?, passes loosely through a bore in the cross beam 89, said bore being of greater diameter than that of the rod so that th r d may be swung slightly to bring the rack into and-out of mesh with thegser 193. Near its upper end the rod .99 passes through a guide 109 p1voted to a lever 11. which is fast to a rock shaft 113. At its lower end the lever 111 has an inturned portion provided with a slot 115 and a spring plunger 117 located as shown vend tending normally to swing the rack 102 away from the gear 103. In order to swing the rack into mesh with thegear a projection 119 formed on the bnidge 43 is adapted to engage .a projection 121 formed on a collar which is fastened to the shaft 113 by a set screw 123. In order to support the shaft 113 yieldingly the bearings 124 of the shaft are provided with upright studs 125 surrounded by coiled springs 127, the lower ends of which rest against supporting caps which are part of the frame 5 of the machine and the uplger ends of which rest against thumb nnts 9. As a consequence of this mounting the shaft 113 is capable of bodily movement in. a downward direction, so that if for any reason the force exerted .upon the lever 111 to turn it about the axisof the shaft 113 is too i eat, no parts of the machine will be broken ilt instead the shaft 113 and the lever 111 will be moved downwardly.

The rack rods 99 and 101 cam-y at their lower ends spring buffers 121 which, when the rods are raised, engage the under side of the cross beam 89, the rods continuing their upward movement until the cutaway portions 107 are oppositethe are. At that time notches 133 are engag bythe plunge-rs 117 so as to hold the rack rods in raised position until the blanir'has passed from engagement with the measuring roll '29. F f Refer!" again to i ig. 8,.one= arpose o the sprin g fil', sleeve .65 andmut 6 9' has been explained. It should he noted, however, thatthe mechanism for moving-ills carriage 31 eaidmeaswring roll 99 ,toitherighe or -left may be adjusted by turnin the thumb nut so as to vary the 181151561 zposrtionxof the-controllingwarm fil lin this 'wagy the machine may be set so as to respond properly to blanks of a given thickness Fnomthe foregoingit will be clear that the thickness of that portion of the blank, which is gripped between the measuring roll 291and the surfaoe 37 at thetime when 91 icon held. In .th

the butters 131 start to raise the cross beam 89,, will determine the effective position of the controlling lever 57 and thereby the operation of the sorting mechanism. In order to vary the locality in the blank in accordance with the thickness of which the blank shall be split and sorted, provision is made for adjusting the initial positions of the rack rods 99 and 101 so as to vary the time at which the buffers 131 engage the cross been: 39. Referring to Fig. 9, 011 each rack rod is a projection 135 with which engage theinner ends of areas 137 feet to a rock shaft 13.9, said shaft having fast to its center an arm 141 the ripper end of which is held between a thumb nut 1 13 pinned to a screw 1 15 and a spring buffer 1 17. The screw 1 15 is threaded into a portion 43 of the bridge which connects the bearings 39 and 41 of the shaft 27.

After the carr age 31 has been moved to the right or the left it is necessary that it be returned to its central position. In vorder to hold it in this position normally and to return it to this position after it has beendisplaced .a rod 151 mounted in the carriage 31 is encircled by two coiled springs 153 (one of which is shown in Fig. 10) the inner ends of wihch contact with opposite sides of a fork 155 fast to the frame of the machine and the outer ends of which contact with adjusting nuts 157 threaded upon said rod.

T he operation of the machine is as follows:

As soon as a blank is fed between the measuring roll 29 and the under surface 37 of the plate the measuring roll, together with its bearings 39 and 11, is depressed thereby forcing the bar 19 to the left as viewed in Fig. 8 and pulling the controlling arm 57 in the same direction. Until the cross beam 89 is raised, this arm 57 is free to swing in either direction according as the blank is thinner or thicker. The depression of the measuring roll 29 depresses the bridge 43, whichconnects the bearings 39 and 41, and by engagement of the projection 119 with the projection 121 on the collar of the shaft 113 rocks the levers 111 into the position shown in Fig. 9 wherein the racks on the rods 99 and 101 are thrown into mesh with their respective gears. The rods 99 and 191 are thereupon raised and presently the buffers 1'31 engage the under side of :the cross beam "89. One or the other .of the segments 91 and 93 is at this time engaged and held Eb the controlling arm 57. For eonwenieeeezlet ithe supposed thattlie segment at ease upward movement of the cross beam 89 *wili raise the slide 79 and force the pawl 173 into engagement with the worm gear '73. There-upon thecarriage 31 moves to the right until the worm gear has run past the pawl. It is held in the extreme right hand position by the engagement of the pawl with the end of the gear until the blank passes the measuring roll '29. As soon as this occurs the spring 53 acting upon the bar 49 raises the shaft 27, whereupon the spring 153 which has been compressed by the movement of the carriage to the right returns said carriage to its original position.

Although the invention has been set forth in connection with a particular machine, it should be understood that the invention is not limited in the scope of its application to the particular machine shown and described.
