CUTTING-MACHINE.

SPEGIFICATION forming part of Letters Patent No. 672,893, dated April 30, 1901. Application filed September 12,1900. Serial No. 29,766. (No model.)

To all whom, it may concern:

Be it known that we, EUGENE R. EDSON and JAMES D. OLOUGH, residents of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Cutting-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in machines for cutting fish or parts of fish r similar materiaL The object of this invention is to provide a machine of the character indicated that is simple and durable in construction and exceedingly effective for the purpose for which it is designed.

With this general object in view and to the end of realizing other advantages hereinafter appearing our invention consists in certain features of construction and combinations of parts. hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation of a machine embodying our invention. Fig. II is a left-hand side elevation relative to Fig. I. Fig. III is a top plan of the machine. Fig. IV is a view in perspective of a portion of the severing-drum c. Fig. V is an elevation, mostly in central verlical section, on line V V, Figs. II and III, looking in the direction of the arrow. Fig. VI is an elevation, mostly in central vertical section, on line VI VI, Fig. V lookingin the direction of the arrow. Fig. VII is a top plan in section on line VII VII, Fig. V. Fig. VIII is an elevation in section on line VIII VIII, Fig. V, showing the inner side of the upper end portion of the knife-bearing'plate fand the lower end of the hopper-wall supported from the said plate. Fig. IX is a vertical section on any one of lines IX IX, Fig. VIII. Figs. IV, VII, VIII, and IX are drawn on a larger scale than the remaining figures.

Referring to the drawings, a and a, designate two vertically-arranged side frames or standards thatare arranged a suitable distance apart, tied together in anyapproved manner, and constituting the main supporting structure or stationary framework of our improved machine. A shaft b is arranged hollow, as shown in Figs. IV and V, to render it light, and consists, therefore, of a cylindrical shell 10, arranged concentrically of the shaft, and two heads 11 and 11, arranged at opposite ends, respectively, of the shell 10 and keyed or fixed upon the shaft in any approved manner. The shell 10 is provided at its external periphery with numerous knife-i bars (1', arranged longitudinally of the shell and at short intervals circumferentially of the shell. Each knife-bar d engages, preferably, a corresponding recess 12, formed in and longitudinally and extending from end to end of the shell 10, and the opposing side walls of the said recess prevent displacement of the said bar circumferentially of the drum.

Two bands or rings 6 and e are sprung or forced in any approved manner upon opposite ends, respectively, of the shell 10 and extend over and hold the knife-bars (1 within the engaging recesses 12. The rings or bands 6 prevent, therefore, displacement of the knifebars radially and outwardly from the drum;

Each knife-bar d is provided with several cutting-blades 15, arranged at suitable intervals longitudinally of the bar and in line endwise. The spaces formed between adjacent blades 15. of each knife-bar register circumferentially of the drum with the spaces formed between the blades of the remaining knife-bars, as shown in Fig. III, so that each blade 15 of each knife-bar forms one of a series of cutting-blades arranged at comparatively shortintervals circumferentially of the drum. Each knife-bar d has its blades projecting preferably radially from the periphcry of the drum.

Relatively stationary upright knives is extend up and down at one side of the drum and have their cutting edges facing the drum. The arrangement of the upright knives is relative t0 the cutting-blades 15 of the severingdrum is such that each blade 15 shall during the rotation of the drum have an orbit or sweep extending between two adjacent upright knives 70. In other words, the knives It and the circumferential series of cuttingblades 15 of the severing-drum alternate, so

' 111,) to which power is applied in any apas to cause the blades 15 during the rotation of the drum to revolve between the knives It. The knives is have their cutting edges extending into close proximity to the peripheral surface of the severing-drum. The upright knives are of course parallel and are supported, preferably, from a correspond-' ingly-arranged plate f, that has as many grooves or recesses f extending from the upper edge of the plate downwardly as there are knives borne by the said plate, and each groove or recess f has the width required to render it capable of snugly receiving a knife 70, and the said groove or recess f is enlarged at its upper end as required to form an upwardly-facing shoulder f as shown very clearly in Fig. IX, that is engaged by a downwardly-facing shoulder formed by a lug or projection k, with which the upper end of the knife that engages the said groove or recess is provided. The side walls of each groove or recess f prevent lateral displacement of the engaging knife, and the shoul- (18lf formed at the upper end of the said recess, in conjunction with the engaging lug or projection is of the knife, prevents dis placement of the knife downwardly upon the knife-bearing plate and is consequently instrumental in supporting the said knife.

The severing-drum is rotated during the operation of the machine in the direction indicated by the arrow, Fig. Vthat is, in the direction required to cause the cutting-blades thereof to revolve from above toward the relatively stationary knives 70. Obviously any fish or parts of fish or other material that is fed into the V-shaped space formed between the upper portion of the severing-drum and the adjacent relatively stationary knives k is upon falling between the said drum and knife-bearing plate f operated upon by the knives 7c and by the drums cutting-blades 15. The knives it make upright cutsthatis, cut or sever the material up and down. The blades 15 of the severing-drum sever the material horizontally or longitudinally of the drum. The blades 15 and the knives 7c are, it will be observed, very positive in their operation. The blades 15 of the severing-drum are instrumental also in feeding the material to the place where it is operated upon by the said blades 15 and the relatively stationary knives it.

As already indicated, the knife-bearing plate f is arranged at one side of the severing-drum. A driving-shaft g,that is arranged horizontally and parallel with the drum-bearing shaft, is located at the opposite side of the drum and supported in any approved manner from the frames or standards a and a. A pinion g is operatively mounted or fixed upon the shaft g at the outer side of one of the frames or standards a and meshes with a spur-gear b, thatis fixed or operatively mounted upon the drum-bearing shaft at the said side of the said frame or standard. The shaft is provided with a driving-pulley g (shown only in Fig.

proved manner.

The knives k are adjustable toward the severing-drum as required to take up any wear upon the cutting edges of the said knives and upon the cutting edges of the blades 15 of the drum, and to this end the knife-bearing plate flies against a frame h,that is arranged at the outer side of the said plate and is adjustable toward and from the severing-drum. The frame It has its upper end hinged or pivoted horizontally, as at h, and on a line parallel with the axial line of the severing-drum to the stationary frames or standards a. The frame it is positively secured in the desired adjustment to each frame or standard a by means of bolts 7L2 and nuts 7L8. Preferably the frame his secured to each frame or standard a in the desired adjustment at its lower end and at a point centrally between the said end of the upper and hinged end of the frame. Each bolt h and the engaging nut 71 that are instrumental in securing the frame h in the desired adjustment to a frame or standard a, are arranged and abut against opposite sides, respectively, of the said standard orframe a, and the bolt-hole a, with which the said frame or standard a is provided for accommodating the location and operation of the said bolt, is elongated, as shown in Fig. I and in dotted lines, Fig. III, in the direction required to accom modate the adjustment of the knife-platebearing frame h relative to the severing-drum.

Means employed for shifting the knife-platebearingframe h inwardly, as aforesaid, comprises, preferably, two screws 1 and l, that are arranged at the outer side of the said frame h, at right angles to the said frame,a suitable distance apart and preferably centrally between the upper and lower ends of the frame, and each screw Z extends through and engages a correspondingly threaded nut 0, that is formed upon or i ntegral with the adjacent stationary standard or frame a. Obviously upon the loosening of the bolts h and nuts h the frame h can by properly manipulating the screws I be adjusted as required to bring the knives of the knife-plate into the desired adjustment relative to the severing-drum.

A not unimportant feature of our invention consists in rendering the knives is adjustable up and down, so that when the said knives become worn at any point sufiicient to render them unfit for further use at the said point an unworn portion of the cutting edges of the said knives can be brought into operation, and to this end the knife-bearing plate at its upper end and upon its upper side is provided with a laterally and outwardly projecting lug f through which extends an upright screw 0, that has bearing in the said lug. Two collars m and n are mounted and fixed upon the screw 1 in any approved manner at the upper end and lower end, respectively, of the lugf and prevent up-and-down movement of the screw independently of the knifebearing plate, and consequently establish operative connection between the said plate and the screw so far as up-and-down movement of the plate is concerned. The screw 0 has its threaded portion extending through a correspondingly-threaded nut 71 that is formed upon the outer side and preferably integral with the frame h. Obviously, therefore, the screw is shifted endwise, upwardly, or downwardly upon turning it in the one direction or the other, and the knife-bearing plate is shifted up or down according as the screw is shifted upwardly or downwardly. The screw has its upper end above the upper collar m provided with a hand-wheel 0.

A hopper r is formed above the space .between the knife-bearing platefand the severing-drum. The material that is to be out or severed into pieces is dumped or fed into the said hopper in any approved manner. The hoppers side walls, that are arranged at opposite sides, respectively, of the V-shaped space formed between the severing-d rum and the knife-bearing plate, slope, preferably, downwardly and inwardly, and the hoppers sloping side wall r, that is arranged at the top of the knife-bearing plate, is rigidly .se-

cured to two bracketsf and f, with which the upper end of the said plate is provided. The said sloping side wall 0" is therefore adjustable up and down with the knife-bearing plate and extends upwardly far enough to accommodate the said adjustment. The remaining side walls of the hopper are preferably vertically arranged and formed by upward extensions of the frames or standards a of the machine.

To prevent clogging of the spaces between adjacent blades 15 of the severingdrum or to prevent adherence or sticking of any material that lodges upon the said drum to the external peripheral surface of the drum, I provide the shell 10 of the drum with numerous orifices 16, preferably forming an orifice 16 between adjacent blades 15 of each circumferential series of blades 15, and introduce steam into the chamber of the drum by means of a suitably-applied steam-supply pipe 25, that has its discharging end in open relation, as shown in Fig. VI, with a port or passage-way b formed in the shaft 1), which port or passage-way is in open relation with the drums internal chamber. Obviously the steam supplied to thedrum at the shafts port or passage-way b escapes from the drum through the orifices l6, and the heating of the drum and the action of the steam directly upon any material lodging upon and having a tendency to adhere to the peripheral surface of the drum will prevent the sticking of the said material to the drum.

Acoveruis arranged concentrically and circumferentially of the drum 0, between the inner side of the shaft 1) and the hopper r. The cover at has its upper end hinged, as at u, horizontally and longitudinally of the drum to the hopper and is provided externally and centrally at or near its lower end with a handle M The cover it performs the function of a guard to prevent injury resulting to or from the severing-drum between the hopper and the driving-shaft, and by swinging this cover upwardly and rearwardly access is conveniently afforded to the exterior of the drum for cleaning, repairs, and other purposes. We would remark also that the hopper-wall 1" extends far enough upwardly and downwardly to accommodate the up-and-down adjustability of the knife-bearing plate f, audthe lower end of the said hopper-Wall preferably overlaps the upper end of the inner side of the kuife'plate and has slots r arranged as required to accommodate the location of the knives It.
