WITNESSES is a sectional elevation taken on line 1111 of Fig. 10. Fig. 12 is a detail section taken on line 12-12 of Fig. 9.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is a receptacle for fish into which the fish are poured in mass by an attendant from a platform 11. The fish are hoisted by suitable hoisting mechanism fromv a vessel in large buckets or cans and the attendant standing on the platform 11 dumps the fish into the receptacle 10. Said fish pass down an inclined chute 12 in large masses of all sizes and at-unequal intervals of time into a conductor 13, the bottom of which is formed byv an endless belt 14 driven by pulleys 15 and 16. .Vater is supplied to the chute 12 through suitable pipes 17.

The fish are carried along by the conveyer belt 14 in the direction of the arrow a and dumped into a boot 18 at the bottom of an elevator constituting a segregator 19. The boot 18 is perforated at 20, 20 to allow water, dirt, fish scales, et cetera to pass therethrough and the fish are pushed through the boot and washed therein by buckets 21, 21 which are attached to an endless conveyor belt which is moved in the direction of the arrow Z) by pulleys 23, 24. The fish by this segregator 19 are thus divided into fractional portions of the original mass of fish delivered to the boot 18 by the buckets 21, 21 which pick up the fish in substantially equal amounts and carry the same upwardly in the direction of the arrow and dump the same into an. inclined chute or conductor 25. It will be seen that the fish are dumped into this conductor in substantially equal quantities at equal intervals of time. The fish are now delivered by the chute 25 to an asserting mechanism 26 for the purpose of asserting the fish so as to deliver fish of. different sizes to different cutting machines,

' it being essential to the best results to be obtained from a cutting machine that the fish should be delivered thereto in substantially equal sizes in equal quantities at equal intervals of time, for, if the fish are of unequal sizes when they come to the cutting machine, they will be either too large or too small to have the heads and tails properly cut by the cutters of said cutting machine. Moreover, it will be understood that if they are not deliverec in equal quantities and at equal intervals of time, the cutting machine will either be running without any fish or will be overstocked so as to waste and spoil the fish.-

The assorting mechanism 26 consists of a rotary drum 27 rotated by a pulley 26'; said drum 27 is made preferably of a pipe and formed as a helix with the spaces gradually increasing between the convolutions 0f the helix from the left to the right (Fig. 1).

arranged a plurality of chutes 28,- 29, 30 and 31. Thus the fish are subdivided into several lots, the fish in each of said lots being of approximately equal size and said lots of fish pass down the conductors 32, 33, 34 and 35 in unequal masses to a like number of segregators 36. As these scgregators are all substantially alike, a description of one will suffice .for all of the'segregators used at this point in the mechanism. (See Figs. 2, 3 and 4.) Y

.The segregator 36 consists of a hollow drum 37 "comprising an outer rim 38 provided with perforations 39, 39, said rim having two flanges 40 and 41 projecting inwardly therefrom. The flange 40 has fastened thereto a gear 42 by means of which.

it may be rotated, said gear and drum being rotatably mounted upon a shaft 43. A series of buckets 44, 44 adapted to contain fish are arranged around the interior of the drum 37 adjacent to the outer rim 38. These buckets are preferably concave-convex, the concave side beingon the inner side of the bucket or that side in which the fish are de posited. Said buckets are arranged within the drum 37 and extend across the interior of said drum adjacent to the rim 38 from the flange 40 to the flange 41. i

A chute 34 leads into the interior of the drum 37 through an annular opening 45, this chute terminating, as clearly shown in Figs. 2 and 3, adjacent to the inner edges of the buckets 44. A guard 46 extends downwardly from the delivery end 47 of theconductor 34. This guard 46 is preferably concentric with the drum 37 and is long enough to extend across the edges of two adjacent buckets.

The drum 37 is rotated in the direction of the arrow 0 and the fish are dumped from the buckets 44, 44 onto a chute 48. That portion 49 of said chute 48 located Within the drum 37 and constituting the inlet of the chute 48 has inclined sides 50 and 51, as seen in Fig. 3, and vertical front and back plates 52 and 53, respectively, said inlet portion 49 of said chute 48 leading into the U-shaped portion 54 which is inclined at a slight angle downwardly and preferably has inclined sides 55 and 56 and a rounded bottomportion 57. The width of the chute at the rounded bottom portion 57 is less-than the length of the shortest fish to be handled'by said mechanism. The chutes 34 and 54 are both provided with water by means of suitable pipes 58 and 59, respectively, controlled by valves 60 and 61;

Adjacent to and beneath the outlet end 62 of the chute 54 are located a pair of U- shaped chutes 63 and 64, Fig. 5 said U- shaped chutes being divided one from the portions then. passing into the chute 63 and the other into the chute 64. The partition being centrally located relatively to the chute 54:, or in alinement with a vertical plane bisecting said last-named chute, there is an equal probability of the fish going into either of the chutes 63 or 64 and, as a matter of fact, it'has been established by practice that the fish coming down the chute 54; are subdivided into substantially equal portions, one half going into'the chute 63 and the other half into the chute 64.

It is evident that the chutes (53 and 64 may be subdivided in the same manner and any number of subdivided chutes ma thus be eventually obtained leading to di erent cutting machines or to different receptacles on a cutting machine and in the present instance the, chute 63 leads to a segregator 66 and delivers the fish in a direction longitudinally of the pockets 67 provided in said segregator and at the inner ends of said pockets. It will be understood that there are arranged side by side a plurality of these segregators 66 and that they deliver fish to a plurality of guides along which, in turn, the fish are carried by suitable mechanism, hereinafter described, to a plurality of rotary carriers having pockets in their peripheries, but as these parts are duplicates of each other, a description of one set of instrumentalities for washing, feeding and cutting the fish will be sufficient for all. (See Figs. 1 and 6). The segregator 66 is fastened to a shaft 68 and is rotated by suitable mechanism such as a pulley. The shaft cs 18 yournalecl to rotate in bearings 69 fast to the frame of the machine. Said segregator consists of two side plates or flanges .70, 70

forming the ends of the pockets (37, 67, and

said pockets are separated one from the other by radially disposed walls 71., 71 which are of ogee curvature in cross section. A shield 72 is supported upon stationary rods 73, 73 fast to brackets 74, 7 4: which, in turn, are fastened to the frame of the machine. A curved guide 75 is provided located beneath and adjacent to the lower end of the shield 72 and this guide has slots 76, 76 therein through which fingers 77 upon the periphery of a rotary feed member 78 pro'ect, said feed member being fastened to a s aft 79 to which a rotary motion is imparted by suitable mechanism (not shown in the drawings), such as a pulley.

' The fish are pushed by the fingers 77 along the guide 75 into pockets 80 which are arranged in series on the periphery of a rotary carrier 81, A series of pipes 82 deliv r waher into the pockets at an angle thereto and of the pockets. 'A shield 84 is arranged adjacent to the periphery of the carrier 81 and as the fish are carried around by the rotary carrier they fall against this shield and finally are pushed by the partitions between the pockets up against a pair of rotary cutters 85, at which time the heads and tails are severed from the fish and pass onto two chutes 86 which convey them into a convenient receptacle 87. The bodies of the fish pass between the cutters and down a chute 88 into a conductor 89 and along said conductor and above brine't-anks 90; If it is desired to salt the fish they are delivered bythe conductor 89 into the brine tank through suitable openings which areclosed by means of drop floors 91. After the fish have been salted sufficiently in the brine tanks they are delivered-therefrom into a conductor 92. If, however, it is not desired to submit the fish to brine, they are carried by the conductor 89 downwardly to the condoctor 93, both the conductors 89 and 92 merging together and emptying into the conductor 93, (Figs. 1 and 9).

The fish in mass pass down the conductor 93 into a receptacle known as a boot 94 for the elevator 95. The fish are floated down the inclined chute 93 in a stream of water supplied bysuitable pipes 96 and this Water enters the boot 94, together with the fish, and thoroughly washes said fish. The water passes out, together with the scales and dirt, through perforations 97 in the bottom of said boot.

The elevator consists of an endless belt or chain 98 with buckets 99 attached thereto which scoop up the fish out of the boot 94 and, carrying them upwardly in the direction of the arrow 07, dump said fish into a chute 100. It will be understood that the buckets 99 thus subdivide the mass of fish which enters the boot 94 into fractional parts thereof. These fractional parts of the original mass of fish which is delivered to the elevator bythe conductor 93 are carried by the buckets 99 upwardly in the direction of the arrow 03 and are dumped at regular intervals and in substantially equal amounts intd the chute 100 which guides the fish into a separator 101, the object of the separator guided by a plurality of conductors 105 to mechanism which will feed the fish to each of the series of circumferential pockets on a rotary'carrier 102, to be laid by said rotary carrier upon fish flakes 144 as they are fed therebeneath by mechanism hereinafter described, (Figs. 7 to 12).

The separator 101 consists of a stationary cylindrical casing 101- having a plurality of outlet pipes 105, 105. {in this case six) broken away to save space in the drawings, these outlet pipes opening out of the bottom of the cylindrical casing 104- and being divided from each other by U-shaped guides 106 in the bottom of the casing 104. Concentric with the casing 101 is a shaft 107 journaled at its upper end in a bearing 108 fast to a supporting timber 109. A rotary motion is imparted to the shaft 107 by a bevel gear 110 fast thereto .and meshing into another bevel gear 111 driven by a pulley 112. The pulley 112 is fast to a shaft 113 and said shaft has fastened to it another pulley-114E which drives a belt 115, whereby a pulley 116 fast to a shaft 117 is rotated. The shaft 117 has a pulley 118 fast thereto which drives the belt 98, said belt 98, in turn, driving a pulley 119 fast to a shaft 120. The shaft 1.17 is journaled in bearings 121 supported upon the beam 109 and the shaft 120 is journaled upon. standards 122 fast to the floor.

To the lower end'of the shaft 117 is tened an elbow 123. The chute 100 delivers fish into the upper endof the elbow 123 and said elbow constitutes an inlet passage for the fish. The fish are delivered from the lower end of the elbow to the upper ends of the pipes 105, 105, said pipes constituting outlet passages from the casing. Thus the fish is subdivided, as hereinbefore described, into substantially equal fractional portions of the original mass of fish delivered by the elevator 95, and these fractional portions 'of the original mass of fish are delivered in equal time and substantially equal quanti ties tothe separator 101 which then, by the rotation of the elbow 123, into which the fish are delivered, still further subdivides the fish insubstantially equal quantities and delivers them to aplurality of COINillChQZ'S 10."), 105. In this case the number of these guides is six,'being thesanic number as the number of subdivisions into which the carrier 102 is divided longitudinally thereof-that is, said.

carrieris divided by partitions 124,121 into divisions.

The fish in each 'of the pipes 105,105 pass down said pipesand, aided by streams of water delivered thereto by suitable pipes 125, passinto chutes 1213, which are prcfcrably U-shaped'in'oross section, and are delivered from said chutes 126' into pockets 127 in a rotary scgrcgator This segregatoi." 123 has a series of pockets 127, 127 opening out of its periphery, the pockets having radially disposed walls 125; of ogre curvature separating one from the other. The segregator 128 is fastened to a shaft 130 messes 127substantially one by one to a guide 136 which is slotted at 137 in order that fingers 138, 138 may pass through said slots and push the fish which rest thereon along the guide 136 and into the pockets 139 of the carrier 102. Immediately beneath the slotted portion of the guide 136 is a rotary feed member 140, said slotted portion of the guide being eccentric to said feed member. The rotary feed member 140 is fast to a shaft 141 and is rotated thereby.

The carrier 102 is provided With a plurality of pockets 139, 139 in its periphery,

said pockets being preferably adapted to contain one fish only and being U-shaped in cross section, with their opposite sides 1 12, 1 12 inclined to the periphery of said car rier and in the direction of rotation ofsaid carrier. Each of the pockets 139 extends 9o transversely of the path of motion of the carrier and said pockets are arranged in a plurality of series, said series, 111 the present- .instancc, extending around the periphery of said carrier in groups of two and being arranged side by side in groups of six. The length of-cone series of pockets 143 measured circurnferentially of the carrier is substantially equal to the length of the reticulated central portion of one of the flakes 144 between the end frames 1 15, 1 15 thereof, and between the two circum'lcrcntially arranged series of pockets i l-3, 143 on the carrier 102 (sec Fig. S) and adjacent to the opposite ends of each of said series, respectively, are two spaces 140, 146 in the periphery of the carrier without pockets and which are substantially equal in length to the spaces occupied by the ends of two of said flake frames nicasurml transversely f'hei'eo'l and the vertical llangeof the angle iron pusher 147, these spaces 1 10, 140 in the periphery of the carrier being provided to ulino with the end portions of the flake frames as they pass beneath the carrier, so that the fish are deposited upon the reticulated portion of the flakes only, hereinafter described.

A shield 148 extends around a portion of the pcriplmry of the rotary carrier 102 and terminates at its lower end adjacent to one of the [lakes 1 1 1. This shield prevents fish from falling out of the pockets 139 as the same pass downwardly until said pockets arrive at the lower end of the shield, when the fish is push 'd along the shield to the lower end thereof and drops out of the pooketofl of the shield and onto a flake 144 which is located immediately therebeneath. The'fl-akes 144 are moved along beneath the carrier bymechanism which will now be described.

The frame 149 consists of two side frames 150, 150 supported upon suitable standards 151, 1151. Angle irons 152, 152 are fastened to the inner sides of the side frames 150 and constitute guides and supports for the endless chain conveyers 153, 153. These endless conveyers 153 extend around sprockets 154, 1154 and 155, 155. The sprockets 154 are fast toa shaft 156 journaled in hearings on the frame of the machine and the sprockets 1-55are 'fast to a shaft 157 also journaled in bearings on'the frame of the machine.

,A rotary motion is imparted to'the shaft 141 by apulley 158 fast to said shaft which is journaled in bearings on the frame ofthe machine. The shaft 141 has a-sprocket. gear 159 fast thereto which is connected by a sprocket ehain 3160 to a sprocket gear 161, said sprocket "gear, in turn, being fastened to the shaft 134 journ-aled to rotate in bearings on the frame of the machine and having a spur gear 162 fast thereto and meshing into a spur gear 163 fast to the shaft 157. Thus the shaft 157 is rotated by the pulley .158, sprocket gear 159, sprocket chain 160, sprocket-gear 161, and spur gears 162and 163.

The sprocket chains 153, 153 are connected together by angle bars 147, 147, preferably formed of angle iron and extending transversely of the conveyor chains 153. These bars are placed at distances apart substantially equal to the length of the flakes .144, 14-4 and act as pushers to push said flakes along the frame in the direction of'the arrow f(Fig. 8), said flakes being guided between the angle irons 152, 152 against mgvement transversely of the frame.

As will be seen by reference to Fig; 7, thereis, in effect, a segregator 128 for each of the double circumferential series of pockets in the carri 102-that is, the segregator 128, as a whole, is divided by partitions 164 into six series of pockets 127, so that the fish, as they are delivered to this segregator, are carried around in the direction ofv the arrow and dropped out of the pockets one by one onto the guide 136 and delivered one by one into the ockets of the carrier 102. The guide 136, 1t will also be noted,;is divided into a series of chambers 165 by partitions 1'66, 166. The number of chambers 165, the number of circumferential series of pockets 127 andthe number of double series of circumferential pockets 143 is six in each case. It will be noted. however, that while it is preferable to have .the carrier 102 divided into a series of pockets longitudinally thereof by means of the partitions 124, 124, yet thesevpartitions may be omitted and the fish laid in the pockets in the carrier 102 innumbers say of six in ea ch of the long pockets thus produced, so long asthe fish are separated into fractional portions from the original mass and directed into suitable guidingmeans, whereby they are finally delivered by a plurality of delivery chutes or guides to the periphery of the carrier 102 at different'points, respectively, longitudinally of said carrier.

The general operation of the mechanism for handling, cutting and flaking fish hereinbefore described is as follows: The fish arepoured from barrels at unequal intervals of time and in unequal quantities into the receptacle 10 (Fig. 1) and pass from said receptacle, aided by water from the pipe 17, down the inclined chute 12 and into the conductor 13, along which they are carried by the endless belt 14 in the direction of the arrow a. At'the end of the endless conveyer 14they are deposited in the boot '18 at the foot of the elevator 19. Water, it will be understood, is supplied at all points in the operation of the mechanism now being described and the fish float along in the water and into the boot 18 and are there washed, the dirt an scales passing out through the perforation 20 in said boot and the buckets 21 pushing the fish through the water in said boot and carrying them upwardly in the direction of the arrow 5 over the pulley 23 where they are dumped in substantially equal quantities at equal intervals of time into the chute 25. The chute 25 conveys these equal quantities of fish at equal intervals of time to the interior of the rotating drum 27 and they are then assorted according to size and passed from said drum down the chutes 28, 29, 30 and 31 to a series of segregators, from whence they are carried on to the cutting mechanisms, only one of which is illustrated in the drawings. The fish pass from the chute 30 down the conductor 34 and are subdivided into equal fractional portions thereof by the segregator 36 in the manner hereinbefore described. They then pass from the segrcgator 36 down the 'U-shaped chutes 54 and6'3 and are delivered thereby to the segregator 66 which divides them into equal fractional portions and feeds them to the guide 75, along which they are pushed by the fingers 77 0f the feed member 78 into the pockets 80 of the carrier 81 of the cutting machine. The heads and tailsare then cut off by the rotary cutters 85, as hereinbefore described, the heads passing down the chute 86 to the receptacle 87, while the bodies pass down the chute 88 to the conductor 89, thence passing along the conductor 89, beingfioated therealong by wa-' ter. Said fish then pass downwardly into the brine tank "'90 and from thebrine tank they pass along the conductors 92 and 93 into the boot as at the end of the elevator 95. The fish are I1OW Wii;l1OUl3 heads and tails and are cleaned in this boot by the Water in the manner hereinbefore described and are carried upwardly by the buckets on the elevator 95 and dumped into the chute 100, by which they are guided into the elbow of the separator 101 from which they pass through the outlet end of said elbow in still further subdivided fractional por tions of the original mass of fish along pipes 125 and chutes 126 into pockets 127 on'the segregator 128. The scgregator 128 delivers the fish one by one to the guide 136 and said fish are pushed along the guide 136 one by one by means of the fingers 138 on the ro tary feed member 1&0 into the pockets 139 in the carrier 102. Said fish are then delivered by the carrier in a series of rows to the flakes 14-4, and said flakes being moved along beneath the carrier by the endless conveyor belts 153, the fish are laid evenly over the entire surface of the flake frames and are then removed by an attendant and put in racks to dry.

It will thus be seen that by means of the mechanism hereinbetore described fish can be dumped into the receptacle 10 in unequal masses at unequal times and by means of said mechanism be automatically separated into fractional portions of the original mass, their heads and tails cut ofi, and the bodies of the fish carried and delivered one by one in rows which extend entirely across the flake and in equally divided spaces on the reticulated portion of said flakes without the assistance of any hand labor, except the attendant who throws the fish into the machine and the two attendants who handle the flakes at the further end, as above set forth. ln fact, one attendant might deposit a large number of fish at one end of the machine, supply the flakes and remove the same with the fish thereon at the other end of the machine.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:
