MINCING AND FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,706, dated July 19, 1887.

Application filed February 13, 1887. Serial No. 928,008. (No model.) i

To all whom it may concern:

Be it known that I, THOMAS WILLIAMs, J r., a subject of Her Majesty the Queen of Great Britain and Ireland, residing at 45 Myddelton Square, in the county of Middlesex, England, engineer, have invented new and useful improvements in Compound Mincing and Filling Machines, of which the following is a specification.

This invention relates to improvements in the well-known class of mincing-machines in which a perforated plate is employed in conjunction with a knife or knives revolving in close con-tact with the inner or outer, or both inner and outer, faces of the said perforated plate for effecting the cutting operation, whether the substance to be cut is forced against and through the said perforated plate in the uncut or crude state in which it is fed in through the mouth or hopper or aftcrit has been partially cut in the machine.

Machines of the class referred to, although well adapted for performing the single operation of cutting up or mincing meat or other like substances, are not adapted (by reason of the obstruction offered by the perforated plate) for simultaneously mincing and forcing the cut substance into skins, and have therefore either been supplemented by a separate and distinct machine known as a filler or stuffcr, which effects the last-mentioned operation separately, or they have been converted into a iiller by removing the perforated plate and knives working against the same and substituting therefor a fillingnozzle, the machine thus converted being then suitable only for forcing the cut substances into skins by a separate operation.

The object of my invention is to enable a mincing-machine of the said class to perform efficiently both the operations of mineing and filling into skins simultaneously, thus constituting an improved combined or compound mincing and filling machine.

To this end my invention consists in the combination, with a mincing-machine of the class referred to, of afilIing-nozzle fitted in any convenient or well-known. manner to the delivery end of the casing, and a supplementary rotary propeller situate on the outer side of. the perforated plate and inclosed within the taper ing or funnel-shaped mouth of the filling'nozzle, said propeller being mounted upon the front end of the axle or spindle of the main forcing-screw or rotating barrel of the machine, which is extended through the center of the perforated plate for that purpose. lhe special function of this supplementary propeller is to take the finally cut or minced portions of the meat after they have passed through the perforations in the plate and propel them onward through the filling-nozzle into the skins.

I prefer that the blade or spiral of the supplementary propeller shall make only about a half-turn round its axis, and thatitsinner end, which revolves in close contact with the outer face of the perforated plate, shall be sharpened to a cutting-edge, so as to act as a knife against the outer face of the said plate.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of an improved combined or compound mincing and filling machine constructed according to my invention. Fig. 2 is a corresponding plan of the machine with the casing open. Fig. 3 is a transverse vertical section taken along theline 1 2 in Fig. 1. Fig. 4 is a face view, detached, ofthe well-known arrangement of perforated plate and rotary knives orstar cutter working in close contact therewith, which constitutes the leading feature of the particular class of mincing-machiues to which my improvements have reference. Fig. 5 is a longitudinal vertical section of the delivery end of my improved compound mincing and filling machine, showing different modes of attaching the lill ing-nozzle and supplementary propeller; also the form of propeller which 1 find to give the best result. Fig. 6 is a corresponding end elevation of the same with the filling-nozzle re moved. Fig. 7 is a transverse section of an improved form of filling-nozzle. Fig. 8 is a longitudinal section of a further modification of the same. Figs. 9, l0, and 11 are longitudinal vertical sections of the delivery ends of three types of existing mincing-machines of the class referred to with my improvements applied thereto.

Similar letters refer to si milar parts throughout the several views.

formed in the two halves of the casing.

Referring to Figs. 1, 2, 3, 4, 5, and 6, a is the casing of my improved combined or compound machine divided longitudinally, the upper half, a, being made to open on hinges b, or to slide longitudinally onto the lower half, as is well understood, and provided with the usual feeding mouth or hopper, c. c is the spindle of a rotary barrel or forcing-screw contained within the said casing and driven by hand or by power. It is supported at the front end in an opening in the center of the perforated plate d, through which it protrudes, and at the opposite end in a long bearing, e, As here shown, the rear portion of the spindle has mounted thereon or formedin one therewith an Archimedean propelling-screw, f, by preference of wider pitch at that partimmediatel y under the feeding-mouth. The forward portion of the spindle carries a series of revolving knives, g, suitably spaced and working through slots in two plates, 71. h", fixed in recesses on oppo-v site sides of the lower and upper hinged portions, respectively, of the casing. The first or inner knife of the series 9 works against the front edges of the plates, as shown in Fig. 2, in lieu of in a separate slot of its own. The ordinary and well-known cutting device used very generally in mincing-machines may be substituted, if desired, consisting of stationary knives fixed inside the casing, and revolving arms or claws mounted spirally on the corresponding portion of the barrel, or vice versa. The crude or un'cut substance, as it is fed in, is propelled forward by the action of the screw f to the cutters g, which effect a preliminary cutting of the substance before it is finally broug'ht under the combined cutting action of the stationary perforated plate at and the knives or star-like cutter t, Fig. 4. The cutter 6 is mounted on the end of the spindle c of the barrel, so as to revolve in close contact with the inner surface of the perforated plate d. k is the supplementary propeller, also fixed on the end of the spindle c. It revolves outside the perforated plate, and is inclosed within the conical mouth Z of the filling tube or nozzle Z. This nozzle is removably fitted, for the purposes of cleaning, into the annular groove or recess inside the delivery endof the casing which receives the perforated plate, as shown in Fig. 1, or it is passed over the end of the I casing and secured by a pinchingscrew, m, as

of the supplementary propeller serves also to force the perforated plate d well up to the cutters i, the recess or groove which receives the plate d being sufficiently wide to allow-of its adjustment therein. The supplementary propeller shown in Figs. 1 and 2 has two convolutions of the spiral or thread; but a better action is obtained with only about a half-turn, as shown in the modification, Figs. 5 and 6.

I form in the interior of the casing of my improved compound mincing and filling machine a series of spiral grooves, 0, so shaped as to present an obstacle to any backward movement of the substances under treatment, while allowing of its free advance toward the delivery end of the machine. 19 p are the usual fastenings for securing the upper half of the casing in its closed position when mounted on hinges.

The interior of the filling-nozzle, when used in combination with the supplementary propeller 7c and perforated plate (I, may be circular, as shown in Figs. 1 and 5; but I prefer to make it with eccentric sides q, forming internal longitudinal shoulders or projections r r, as shown in Fig. 7, to assist the forward movement of the minced meat by checking any tendency it may have to rotate with the supplementary propeller inside the mouth lof the filling-nozzle;'or the interior of the mouth I may be formed with spiral angular-shaped grooves s, as shown in Fig. 8, to assist the action of the supplementary propeller.

In the types of existing mincing-machines,

Figs. 9 and 10, the substance operated upon is forced in an uncut condition by a forcingscrew, f, against a stationary perforated plate, d, and is cut by a knife, i, revolving in close contact either with the inner surface of the said plate (see Fig. 9) or withthe outer surchine before referred to the functions of the machine ceased when the substance had passed provision being made for imparting any further impulse to the cut substance which fell inertly from the perforations and had to be fed into a separate and distinct filling-machine when required to be forced'into skins.

Now, by the combination, as shown, with a mincing-machine of the class referred to, of the filling device consisting of the nozzle Z Z and supplementary propeller k, revolving therein on the outer side of the perforated plate, afresh impulse isimparted to the minced substance, by which it is forced into skins direct as fast as it issues through the perforated plate. s

I am aware that prior to my invention mincing-machines have been made wherein the meat was cut by spirally-disposed rotary knives or claws alone, which served also to propel the'cut substance through a filling-nozzle, and therefore I do not claim, broadly, the effecting the two operations of mineing and filling by one and the same machine.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination, in a compound mincing and filling machine, of a filling-nozzle and a supplementary propeller revolving in the mouth thereof, with a perforated cuttingplate, knives revolving in close contact therewith, a casing, and a forcing-screw inside the casing of the machine, as'specified.

2. The combination, in a compound mincing and filling machine, ofa casing, a filling-nozzle, and supplementary propeller revolving in the mouth thereof, with a perforated euttingplate fixed in the end of the casing, knives revolving in close contact with the inner face of said plate, and a rotary spindle carrying a forcingscrew and a series of cutters working against slotted plates fixed on opposite sides of the interior of said casing, substantially as specified.

3. In a compound mincing and filling machine, the supplementary rotating propeller formed with a cutting-edge revolving in close contact with the outer face of a perforated cutting-plate fixed into the delivery end of the easing, as specified, combined with the casing, forcing-screw, and cutting-plate, substantially as described.

4. The combination, in a compound mincing and filling machine,of a conical filling-nozzle, having eccentric sides q and internal longitudinal shoulders or projections r, with a supplementary propeller and a perforated cutting-plate having knives revolving in close contact therewith, as specified.

5. The combination, in a compound mincing and filling machine,of a conical filling-nozzle, having internal angular projections, with a supplementary propeller and aperforated cut ting-plate having knives revolving in close contact therewith, as specified.

In witness whcreofI have signed my name in the presence of two subscribing witnesses.
