Specification of Letters Patent.

Patented Mar. 18,1913.

Application filed March 29, 1910, Serial No. 552,257. Renewed August 9, 1812. Serial No. 714,305.

To all whom it may concern:

Be it known that I, Howann B. Rrrcmn,

of Hyde Park, in the county of Norfolk and a specification.

This invention has for its object to tovide a machine for asserting and gra mg elongated bodies such as sardines or other relativel small fish preparatory to cooking and pac ing. I i

While my invention may be used for assorting various kinds of fish or other articles I will hereinafter designate the articles assorted by the machine as sardines, it being understood, however, that this term is used for convenience and is intended'to designate any kind of fish, the asserting of which-is desirable.

The machine has for its object'to provide a simple and eifective machine adapted to readilyassort and grade large masses or quantities of sardines.

The invention also has for its object to provide a machine of this character which shall be adjustable so that a mass of sardines may be assorted into as many grades as may be desirable, the machine being so adjustable that it is capable of delivering, in each grade, fish of any desired size.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings which form apart of this specification-Figure 1 represents a top plan view of an assorting machine 'embodyin my invention. Fig. 2 represents aside view of the same. Fig. 3 represents a bottom view, the machine being inverted. Fig. 4 represents a section on line 4-4 of Figs 1 and 2. Fig. 5 represents an enlargement of a portion of Fig. 2, certain parts being broken away, and other parts shown in section. Fig. 6 represents an elevation of one end of the machine. Fig. 7 represents an elevation of the opposite end of the machine. Fig. 8 represents a fragmentary top' view showing one end of on of the grids.

Similar reference characters indicate the same parts on all the figures.

The machine as illustrated in the drawings includes a grid-supporting frame composed of side members 12, each of which is preferably composed of. elongated metal rods or tubes connected at one end of the frame by transversemembers 12, these being connecte'd by transverse members 12, constituting one end of the frame, and transverse members 12constitutingthe opposite end of the frame. The member 12 is provided with an ear 13 which receives a pivot stud 14 which is supported by a head frame composed of uprights 15 and a transverse bar 16 connecting said uprights. The ear 13 and stud 14 constitute a hinge or pivotal connection between the grid-carrying frame and the head support. The pivot stud 14 is preferably mounted to rock or oscillate on the supporting member 16 to permit a variation of the inclination of the grid-supporting frame as hereinafter described.

The grid-supporting frame is provided with aseries of grids 17, three of which are here shown, these grids being composed of bars extending length wise of the frame and separated by spaces through which sardines of .a given size are adapted to pass into a box or receptacle, 18. Each grid is preferably adjustable to vary the width of the space between its bars, the construction which permits this adjustability being fully described hereinafter. v v

. Between the grids 17 are cross bars 19 having guiding ribs 20 between which sardines may pass from one grid to the next, the frame and the grids being inclined and said inclination, together with the horizontal oscillation of the frame as hereinafter described, causing the sardines to slide along the grids and across the cross-bars 19, the guides 20 causing the sardines to pass end-wise from one grid to the other. Said guides are preferably triangular in cross section, so that they present sloping sides, as shown in Fig. 4.

Thesardines are delivered to the machine through a chute 21, which may communicate with a suitable hopper, not shown, and discharge the sardines upon adelivering table 22 which is attached to the grid-supporting frame and is inclined therewith, said table being adapted to position the sardines discharged upon it so that they will extend substantially parallel with the grid bars and will, therefore, pass length-wise from the delivering table to the first grid. The

delivering table is provided with longitudidti nal ribs which are preferably formed by bending or corrugating the sheet metal plate of which the table 29. is made.

lit will now be understood that the higher end of the grid-supporting frame is hinged to a head support, and that sardines discharged upon the delivering table 22 are caused by the inclination, and by a shaking motion or oscillation of the table, to slide down the delivering table to the first grid, where all below a certain size are separated from the rest and pass downwardly between bars of the grid, the larger sardines passing across the first cross-bar it) to the second grid where they are again sorted. The sardines remaining on the second grid pass to the third grid where the final asserting is effected.

The lower transverse member 12 of the grid-supporting frame is provided with rollers 23 (Fig. 7) which are adapted to run upon a transverse traclt 52d, forming a part of a fixed foot frame, or support, located at the lower end of the grid-supporting frame. Said foot frame includes fixed uprights 25 to which the track 24- is attached, said track constituting one of the members of the frame, the upper portions of said members being preferably connected by a transverse frame member 26. The foot frame is provided with mechanism for imparting a horizontal reciprocating movement to the lower end of the grid-supporting frame, the latter being thus oscillated on its pivotal connection'with the head frame. Said mechanism, as here shown, includes a shaft 2? journaled in bearings in the 'foot frame and provided with a face plate 28, and a connecting rod, or pitman, 29 engaged at one end with a wrist pin 30 on the face plate 28 and at its opposite end with a stud 31 affixed to the member 12 of the gridsupporting frame.

The shaft 27 may be rotated by any suitable means, such as a belt running from a pulley on a driving shaft, to a pulley 32 on the shaft 27.

The uprights 15 of the head frame and the uprights .25 of the foot frame are preferably adapted to be attached at their upper ends to beams or other overhead supports, and at their lowerends to a floor, provision thus being made for firmly securing said frames in place.

The inclination of the grid-supporting frame may be varied by vertically adjusting the transverse member 16 of the head frame on the vertical members 15, and by vertically adjusting the track 2d and the bearings of the shaft 27 on the vertical members of the foot frame. As here shown, the head frame member 16 has collars 38 at its ends which are slidable on the uprights 15, and are adapted to be secured at any desired height on said uprights by pins or noaaeoa bolts .84: adapted to enter holes 35 located different heights in the uprights 15. The ends of the transverse track 24- are here shown as attached to collars 36 which are slid-ably mounted on the uprights 25 of the foot frame, and may be attached thereto at different heights by pins 3'?" adapted to enter holes 38 formed for their reception in the uprights 25. The foot frame is provided with extensions which include uprights 39.

The bearings 40 in which the shaft Q? rotates, are formed on collars d-l which are slid-ably mounted on the uprights 25 and 39 and may be supported at various heights by pins adapted to enter orifices in said uprights. litis obvious, however, that any suitable means may be provided for supporting the ends of the grid-supporting frame, and for supporting the shaft 27, at various heights.

As before stated, the bars of the grids 1? are preferably adjustable relatively to each other to vary the space between the, bars and thus adapting each grid to permit the separation of sardines of any desired size from a mass or'stream passing over it. The preferred construction of each grid Whereby this adjustability is secured, will be next described, it being understood that the construction is the same in each of the grids, so that a description of one will suffice.

Considering for the purposes of this description, the first or higher grid, let it be understood that the grid is composed of a non-adjustable central bar 42, a series of adjustable bars 43 at one side of the central bar and a series of adjustable bars .44 at the opposite side of the central bar. The end portions of the central bar 42 are provided with bearings 4-5 which embrace two transverse shafts 46, the end portions of which are journaled in hearings in plates ll, at tached to the. side members 12 of the grid frame, the said bearings being confined between collars d8 afixed to said shafts. The shafts 46 are prevented from moving endwise by collars 49 hearing on opposite sides of one of the plates l7, and by a. collar 50 bearing on the inner side of the other plate at". (blee Fig. 4.) The central grid bar is, therefore, held. against lateral movement in either direction. Each shaft- 46 is provided at one end portion with a right hand screw thread 51 and at its opposite end portion with a left hand screw thread 59. The outermost adjustable grid bar 43 is provided with nuts 58 which engage the threads 51 of the shafts 46. The outermost adjustable grid bar dat is provided with nuts which engage the screw threads 52 of the shafts 4E6.

With the opposite ends of the adjustable grid bars 4-3 are connected two lazy-tongs 55, and with the opposite ends of the adjustable grid bars 44 are connected two lazyltdli tongs 56. The inner members oft-he said lazy-tongs and 56 are pivoted at 57 to the bars 45; the outer members ofv the lazytongs 55 are pivoted at 58 toithe. nuts 53; the outer members-of the lazy-tongs 56 are pivoted at 59 to the nuts 54. The intermediate members of the lazy-tongs 55 are pivoted at 60 to the ends of the adjustable grid bars 43; and the intermediate members of the lazy-tongs 56 are pivoted at 61 to the ends of the grid bars Means are provided for simultaneously rotating the shafts 46, said means including sprocket wheels 610 attached to said shafts, a sprocket chain 62 engaged with and conmeeting said wheels, and adriving sprocket wheel 63 located between the she ts 46 and engaged with the chain 62, the said driving wheel 63 being rotatable by a crank 64 (Fig. 7 engaged with a squared shank 65 attached to the hub of the wheel 63.

The rotation of the shafts 46 inone-direction causes the simultaneous elongation of the lazy-tongs 55 and 56 and a simultaneous outward movement of the adjustable grid bars 43 and 44, provision being thus made for the differentially moving and adjustable grid bars in such manner as will keep the same uniformly spaced apart under all adjustments, so that an elongation of the z lazy-tongs, simultaneously increases the width of the space of all the grid bars to the same extent. The contraction of the lazytongs caused by the opposite rotation of the shafts 46 causes a simultaneous decrease of the width of the spaces between the grid bars.

The lazy-tongs are supported by transverse bars 66 (Fig. 5) attached to the grid frame and arranged to support the under sides of the lazy-tongs, -the latter being in sliding contact with the bars 66."

The first grid of the series preferably has a larger number of bars than the second, and the second a larger number than the third, the lazy-tongs connected with the second and thirdgrids being so proportioned that when all the lazy-tongs are fully contracted the spaces between the bars of the second grid will be slightly wider than those between the bars of the first grid, :1 corresponding difference existing in the relative spacing of the bars of the second and third grids.

It will be seen from the foregoing that provision is made for adjusting each grid to vary the size of the sardines passing through it, and that each grid is adjustable independently of the others.

651 represents a hood which is located over the table 22, and is formed to prevent the scattering of the sardines issuing from the chute 21.

661, 661 represent inclined guards attached to the side members of the guide The sprocket wheels 61 and 63 and the chain 62 are located in a casing formed by the frame members 12, one of the plates 47,

and a plate 67 (Fig. 4) secured to one side of the grid frame.

My invention may be embodied in a machine having one or any other desired number of grids, so far as the adjustable construction of the grid is concerned.

My invention is not limited to details of construction here shown and described, and the same may be variously modified without departing from the spirit of the invention. V

The adjustable grid bars43 and 44 may be sug orted by transverse rods 68 (Figs. 9

and 5 suitably attached to the grid frame and extending across theunder sides of all the bars including the central bar 42, the ad ustable bars 43 and 44 being in sliding contact with said rods.
