SLICING-MACHIN E.

Specification of Letters Patent.

Application filed October 1, 1917. Serial No. 194,112.

To all 'whom it may concern.'

Be it known that we, WILLIAM H. GAR- LooK and WiLLIAM J. STUBBE, 'citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful I mprovements in Slicing-Machines, of which the following is a specification. This invention relates to slicing machines; the object of the invention is to provide an inexpensively operated and efficient machine whereby the slicing of bread, fish or other articles may be performed with despatch and uniformity.

In some respects the present invention is in the nature of an improvement upon the machine disclosed in U. S. Patent No. 1,212,045, issued to us January 9, 1917, and to which reference may be had.

As compared with the prior machine, the principal features of the present invention consist in the novel loaf-feeding means; devices for holding the work down upon the table to accommodate any inequalities in the thicknesses or shapes of the loaves; improved manner of assembling and regulating the' cutting knives; and guiding means forvdirecting the slices of bread from the knives. The invention further consists inthe novel arrangement and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal section of a machine embodying the present invention. Fig. 2 is a plan view of the same, shown partly in sec- 'tion through 2-2 of Fig. 1. Fig. 3 is a fragmentary view partly in section and partly in perspective, said section being taken through 3-3 of '.Fig. 2. Fig. 4t is a transverse vertical section, taken substantially through 4.-4 of Figs. 1 and 2. Fig. 5 is a fragmentary plan view of the complementary knife frames. Fig. 6 is a front elevational view of a portion of one of said knife frames. Fig. .7 1s aA sectional' view through 7-7 of Fig. 6. Fig. 8 is a perspective view of a part of one of the workfeeding attachments. Fig. 9 isa detail longitudinal elevational view of one of the frame members. Fig. 10 is a sectional view through d10- 10 of Fig. 9.

Supported upon a suitable framework 1 of the machine is a table comprising parts y2 and 21 which are longitudinally spaced to accommodate a plate 3 therebetween. At 'each side of the frame is a slotted post l;

- movement thereof.

which serve as guides for vertically movable frames or sashes carrying gangs of serrated cutter knives 5. Each of sald sashes is formed with side rails 6 and horizontal top and -bottom rails 7 and 8, respectively. Said top and bottom rails are provided with transversely arranged slots 71 and 81 to accommodate shanks 9 and 91 of knife attachments having bifurcated heads 10 and 101 into which extend the ends of the' respective knives which are secured thereto by pins 11. The shanks 9 and 91 are screw-threaded for nuts 12 and 121 whereby the heads 10 and 101 are-secured in adjusted positions` laterally of the respective sashes.

Extending downwardly through the slots 72 of the upper rail 7 of each sash (see Figs. 5 and 6 )are adjustment screws 13 engaging in screw-threaded holes provided in the shanks 9 whereby the elevation of the upper heads is adjusted to regulate the tension of the knives.

The cutting edges 51 of the various knives of both sashes arearranged Vin a vertical plane indicated by :z2- 1n Figs. 1 and 5.

Said knife-carrying frames or sashes are reciprocated to move simultaneously in opposlte directions, as by means of eccentrics 14.-141 on a power-driven shaft 15, said ecthe aforesaid supporting framework 1, said chain being driven by means of sprocket wheels 22 secured to a transverse. shaft 23. The latter has mounted thereon a pulley 231 about which passes a belt 25 from a pulley 151 on the shaft 15.

Extending through the journal bearings provided in links 181 of said chain, are transverse rods 26 to which are secured radially disposed pins orspurs 27 adapted to extend through slots 28 provided in the table part 2 to penetrate the bread or other article being sliced, and e'ect the feeding The action of said spurs is regulated by means of controllers provided on the ends of the rods 26, each having two studs 29 \girder members 21.

and of unequal lengths, the long er and heavier ones 29 being preferably d1sposed to have their axes in a plane with the axesby being carrieddownwardly with the chain `about sheaves 191 and during which the prongs are caused to slope rearwardly 4by means of curved guide plates 34, one on each work as it traverses the same.

side, being engaged therespective studs As illustrated in Figs. 4 and 10, the ways 31 are of insufficient depths to allow the studs 29 to enter therein. -The plate 3, as best shown in Fig. 3, is seated at its forward and rear ends upon flange elements 35 and 36 provided on the table parts, the forward end of said plate being sloped, as at 37, to engage a ainsta correspondingly sloped edge of ta lepart 2 while belng held down by screws 38 at the side and rear of the ate. v

p At the frontedge, said plate is formed with comb-like teeth 39 and afford therebetween slots 391 through which operate said slicin knives, while at the rear thereof and in axlal alinement with the respective slots are slots 40 through which protrude disks 41` carried by an arbor 42 j ournaled in bearings, not shown, provided on the underside of the plate 3.

Included in the invention are presser devices for holding down upon the plate 3 the Such pressure devices, as best shown in Figs. 1 and 4, comprise a number of rings 43 mounted upon transverse bars 44 and 441v of less diameter than the openings within said rings and supported from their ends in boxes 45 and 451 movable vertically in guides provided in branches 46 and l461 lof the e posts 4.

47 represent springs acting to yieldingly hold the boxes 45 and 451 and the associated bars 44 and 441 in their lowermost positions.

The operation of the invention may be explained as follows j The operator standing in front of the machine places the articles to be sliced, such as a loaf of bread indicated by L in Fig. 4, upon the front end of the table, whereupon the conveyer prongs 27 engage in the loaves and feed the same toward and through the sashes carrying the knives 5 to be sliced thereby, the slices thus produced being pushed ahead onto the table part 21. Durwhich, at the higher portions of the loaves,

lng such action the conveyer prongs are successively brought into operative engagement with the loaves at the front end of the table and are thence progressively movedthereby by the traveling prongs until the latter are withdrawn, as before" explained.

While passing through the knife sashes,

the loaves are firmly held down on the -tablc part 2 and plate 3 by means of rings43 75 are resiliently held thereagainst by .means 1 of rods 45 which are urged downwardly by .v the springs 47.

' By reason of the rings being loosely mounted upon said bars 44.-.-441, they will accommodate themselves tol any irregularities or low 'places in the loaves, as will be understood lfrom an inspection-of Fig. 4.

When being sliced, the disks 41 extending into the interstices between the slices, will serve to direct them fairly upon the delivery part 21 of the table. When it is desired to change the thicknesses of slices, the plate 3 is removed and the knives 5 are shifted laterally'into desired positions after loosening nuts 12-121 and screws 13. Being thus adjusted, another plate such as 3, in which the slots 39 and the disk 41 are properly spaced, is inserted in lieu of the one removed.

In the present embodiment of our invention, the cutting edges of the knives of both sashes are arranged to be substantially in the same transverse vertical plane and in consequence the opposite movements of the tWo gangs of knives will have no effect either to raise or lower the articles being sliced, the pressure rings 43 serving to steady the articles as they travel through the sash. 1015 The operation and advantages of the invention will, it is thought, be understood from the foregoing.

What we claim, is-.

1. In a slicing machine, cutter knives, a frame for said knives comprising side bars and top and bottom rails, said rails being provided With horizontal slots, knife-attaching heads having screw-threaded shanks extending through the respective fra'ne 115 rails, meansvfor adjusting the vertical psitions of the heads with respect to the upper frame rail, and nuts engageable with said shanks to secure the heads in both vertical and horizontal adjustments.
