l I(s claims. (cl. 1464-139 y f Ihis invention relates to improvements in machines for slicing ,stationarily-positioned ybakery products. n 1

One of the objects of `this invention is to produce a horizontal slicing machine in which the product to be sliced is maintainedin stationary position and-cutting knives are mechanicallyreciprocated while being moved in an arcuate path through said product.

Still another object of my invention is to f provide a mechanism having one or vmore mechanically-reciprocated, slicing knives mounted in a radially-extending operating frame Amovable in an arcuate path, combined with means for retaining the product to be sliced in a Xed position in the arcuate path of the reciprocating knives in said radially-extending and arcuately-movable operating frame, whereby conveying devices for the productmay be 'eliminated andthe slicingmachine construction may be greatly; simplied.

Still'another object of my-invention is'to produce a horizontal slicing machine ofthe type specified having a stationary product-supporting table, combined with a radially-projecting operating frame pivoted at one edge. on said supporting table and free at its opposite edge to enable manual arcuate movement over saidy supporting table of said'frame about its pivot, said operating frame having one or more horizontally-disposed slicing knives mounted therein for .mechanical reciprocation, power means is employed for r'eciprocating said knife or knives, and means is provided on Vsaid supporting table for maintaining the product in a stationary position within said path of arcuate movement of said reciprocating cutting knives.

Still another object of my invention is in a horizontal slicing machine of the 1 character specified to provide a pivoted radially-disposed operating frame having mounted therein one or more mechanically-actuated reciprocating knives, a stationary.product-mounting table on which said radially-disposed operating frame is pivotally movable in an arcuate path during mechanical reciprocating movement of said knife orknives, means on said table is provided for retaining the product in stationary position relatively to the said arcuately-movable operating frame and means is also provided on said table for supporting said operating frame during its said arcuate movement.

Still another object of my invention is in a machine ofthe character specified to provide in combination with a pivotally-movable operating frame, a motor mounted on and movable with said pivoted operating frame for' operatingvlan eccentric to reciprocate the knife or knives and thusv to cause continuous andunimpeded movement of said eccentricduring arcuate operating movement of said operating frame.

Still another object of my invention is to provide a pivoted arcuately-movable carrier member or bracket including a casing for mounting eccentric mechanism adapted vto reciprocate one or more knives in a radially-projecting operating frame and to carry in said movement a motor for actuating said eccentric mechanism, whereby said radially-projecting operating frame isunitarily connected with said motor and both may be moved by hand-manipulation to produce an unimpeded slicing engagement of said knife or knives with a stationary bakery product. Y

Still another object of my invention is in a machine of the character speciiied, to utilize for the reciprocation of thevslicing vknife vor knives mechanism that will be strong and durable and nwill eliminatestrains and stresses that have here- `bifurcated connecting rod adapted to engage and embraceV intermediate itsends the articulating joint or -connection with the eccentric rod or strap, and to enable such joint orconnection to be varticulated within a rod-bearing member having a'diameter'adapted to receive and cooperate with. said heavy bifurcated -or two-part rod 'so as to permit both articulation of the joint and reciprocation within said bearing, andl thus to avoid much of the strains and stresses heretoforev imposed upon such rods andto eiectually resist such strains as'may be imposed thereon.

. With these and other objects in view, the invention comprises the combination of members and. arrangement of parts so combined as to co-act and cooperate with each other in the lper- -formance of the functions and the accomplishment of the results herein contemplated, and comprises in one'of its adaptations thek species or preferred form illustrated in the accompanying drawings, in which: f

Fig. 1 is ajview in plan of a machine embodying my invention;

Fig. 2isa view in side elevation of themachine shown in Fig. 1 viewed from the section line 2 2 ofFig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 2,

Fig. 5 is a section on the line 5-5 of Figs. 2, 3 or 4, looking in the direction of the arrows.

Referring now to these drawings, which illustrate a preferred embodiment of my invention, a support, preferably comprising a table I composed of a wooden body 2 having a metal surfacing pl-ate3 is provided at one side thereof with a pivot-pin 4 for the pivotal mounting of my slicing mechanism which will thus move in an arcuate path over the table I. As shown, the pivot has a screw-threaded connectionwith a fiat semi-circular and heavy metallicbearingplate which is suitably mounted on the table, and,..as shown, is fastened with its diametri'c' edge' 'registering with the edge of the table 'and its arcuate edge extending inwardly so that the fiat surf-ace of the plate will function as a flat, hard and smooth bearing for the pivoted slicing mechanism 'during' vits v-arcuate movement ".Said pivot, as shown, extends vupwardly Afrom said plateatfa rightangle thereto, and-said-table isalso l`preferably provided-between -itsfrOntfand rear edges with position-maintaining- -or holding members vforfholdingthe product to be'sliced in-st-ationary position vvduring movementof vthe reciprocating 'knife -or "knives therethrough. rIn vthe `form shown; the lproduct-'holding' member 1 vcomprises al pair' vof angle- Ibars' positioned in angular` 'relation -to1 each -otherand having upright 4flanges fla -so thatabakery-productor cake 8 positioned substantiallyfatthe' center of the supporting table,las shown-in dotted lines in Figs. l and 3,-w-ill'be maintained in 'stationary posi-tion and held from shifting during subsequent 1horizontal slicing thereof by the'- slicing mechanism.

In accordance with thev preferredv form 'of .my

AIn the emlbodiment shown, the'frame I2 'has four hori- -zontal partitions or iingers'to divide the 'same into three'knife compartments I4 and Yis providedzat 'its inner edge 1with asingle knife-holder pin I 2e which extends through said three knife-mounting-compartments. In the preferred embodiment of my invention shown, the frame' 9 isj provided at opposite edges of the opening I I with posts I6 and I1, each containing a series of spaced knifealigning notches, and the portion ofthe frame 9 comprising the top 'ofthe'opening II is'pr'ovided Vwith a' guard -member 'I 8" extending' to 'opposite sides of the opening I I over the knives I3;

I preferably utilize a 'single knife-mounting frame I2 and provide' a single eccentric 22 yfor re- 'invention shown, the operating frame 9 is mounted 'on acarrier unit 2| which carries the motor, operating frame and eccentric casing, and comprises the pivotally mounted eccentric casing f2 Ia forsaid single eccentric 22 and an upwardlyextending bracket 2|b for connection of the operating frame 9.

, As illustrated, the eccentric 22 is suitably mounted '1in lhorizontal bearings;` 23 and is providedwith-an adjusting'rod 2'4 having an; articulating joint 25 which is connected with a connect ingrod` 26 `(which, inthe form of my invention shownpis integrallyiconnected'with the knifemounti-ng 4frame I2. .The 'eccentric v22 is, 'ras shown; :mountedupon a shaft 2'lrotated by a'movtor 28 'which is 'preferably mounted in the lcarrier unit 2I and positioned above 4the casingI 2|@ with its shaft'Z-I ,disposed vertically andenterin'gs'aid casing" 21B' to'rotate the eccentric k22.

As illustrated,the'integral vertically-extending bracket 2lb is connected 'with .the conventional supporting. feet of the 'motor 28' .and secured lto said bracket. bylbolts 29' and ythe same bolts' are preferably l:employed to connect to the 'said bracket 'the operating frame .9k which' is formed separately from the uniti 2|..

By' 'carrying' the motor 28., :as illustrated, the reciprocating movement 1 of the :knives will ,be completely unimpeded' y:during 'the arcuate move- .mentiof` the operating frame.
