GEORGE II. IIIESSEIING, OF ST. LOUIS, MISSOURI.

ROTARY CUTTER.

SPECIFICATION forming part of Letters Patent No. 394,803, dated December 18, 1888.

Application filed December 2l, 1887. Serial No. 258,616. (No model.)

To all whom it may concern:

Be it known that I, GEORGE 1I. WEssELINc, ofthe city ot" St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Rotary Cutters, et' which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this speciiication, and in which-d Figure I is a back view of the machine with parts broken away to show the action of the slicer-disk with its geared periphery and the pinion that actuates the bevel-gear on the egg-beater shaft. It also shows the latchhook that holds the nest of bean-hoppers in their place. Fig. II is an end view with parts broken away to show the action of the feeder, slicer, and internal gear. Fig. III is a vertical section taken online III III, Fig. I, showing the Slicer-disk, its set-screw attachment to its operating-shaft, and its geared connections with the rotary egg-beater shaft. Fig. IV is a detail view, part in section, of the feedway to the slicer and grater with the pivoted feed-shutter, the latter shown also in elevated operative position in dottedlines. Fig. V is a view in elevation of the egg-beater with part broken away to show the sleeve attachment to its rotary shaft. Fig. YI is a perspective view ot the hoppers for attachment to the feedway when green beans or other small vegetables are to be sliced. Fig. VII is a vertical section of the grater-disk with the set-screw that secures it toits operati11g-shaft. Fig. VIII is an enlarged detail section of the grater-disk, showingone ot' t-heburrs in crossseetion and Fig. IX is an enlarged detail perspective of said grater, showing the open mouth of the burr.

The invention relates to a domestic. machine which, besides for household use, is also especially adapted for use in hotels, restaurants, bakeries, confectioneries, &c., for slicing vegetables, grating, and egg-beatillg purposes; and the invention consists in features of noveltyhereinafter fully described, and pointed out in the claims.

Referring to the drawings, in which similar igures of reference indicate like parts in all the views, l represents the back, 2 2 the ends, and 3 the front and 4; the bottom bar, of the trame, in and attached to which the various combined devices pertaining to this machine are secured.

5 is the clamp and (l the set-screw, which are used to secure the frame to the table or bench 7 on which it stands. As shown, along clamp is used, so that it will reach from the edge of the table to hold the bottom cross-bar whichever way the frame is set, either as in Fig. II or as in Fig. III. I have shown one clamp; but, especially in large machines, a second clamp may be used and vfound serviceable.

S represents an inclined slide, preferably of tin, galvanized iron, or other sheet metal. The said slide is provided with a handle, 9, beneath it, for convenience in handling, and it runs in channel-grooves l0 in the end pieces that are formed on anincline from the back downward. This slide receives the slicings and gratings as they drop from the knives and grater and deposits them from its chute end ll into any suitable vessels set to receive them.

l2 is the main axle-shaft that carries the rotary slicer-disk 1S or rotary grater-disk 14. The said axle has its bearings, relatively, l5 and 1G, in the front and back of the frame. The slieer has gates or openings 17 through it for the passage of the sliced vegetables in the vicinity of the slicerknives 1S, which knives are secured to the disk by screws 19. The rake or thickness of the cut ot the knives is regulated by set or thumb screws 20, that are seated in screw-threaded perforations in the l disk, and vas they are turned project against the knives and force them outward, and are thus made to regulate their rake and the consequent thickness of their cut.

The Slicer-disk, which is preferably of cast or sheet iron, is secured to a hub, 2l, at its eenter by any suitable means, and said hub has a project-ion back of the disk and a tubular bore, 22,within it for seating the main axle. A thumb-screw, 23, which has its screw-seat in the back projection of the hub, is made to screw down onto or into the axle to rigidity the connection of the disk to said axle and secure its rotation therewith when the machine is operated.

A pinion-wheel, 24:, is keyed onto or near IOO the rear end of the main shaft, and its cogs 25 mesh into cogs 2o of the gear-wheel 2T, which is keyed onto the operatingt-shaft 2S, which has its bearings 2.() and 30, relatively, in the journal-box carrier-bar ill, which is secured in the rear of the't ame and to the end pieces of the same by the screws 32, and in a journal-ln'acket, 233, which is secured to one of the end pieces of the :frame by screws or bolts Si. The j ournal-box carrier-bar 31,besides carrying the bearing 2f) of the operating-axle, also carries the main axle-bearing ltj aforesaid. A capholder, 35, provided with a wooden or other suitable upper bearingcushion, 3o', lits down over the main shaft at its near end to hold it in its bearings, and is secured at its rear end by the pivot-pin 37, on which it is raised to its open position shown in dotted lines, (see Fig. L) when it is desired to unship the shaft. A thumb screw, 233, holds said cap home on the shaft when the machine is in operation.

39 represents the crank-handle that turns the machine. It is keyed or otherwise secured ou the operating-shaft. l have shown the machine as turned by hand with a crank, as in all except very extensive establishments it would preferably be so worked; but it is evident that a drive-pulley could easily be keyed on the end of the operati iig-shaft in the place of the crank-ha'ndle, and a pulley-band connect it with any suitable power.

'lhe rotary grater-(lisk 1st, made of tin, gal vahizcd iron, orv other suitable sheet metal, has a hub, t0, secured to the center of the disk, and by radial arms -ll with the peripheral rim or tire l2, which hub is similar to that on the rotary slicerdisk, except that it is made slightly larger, so as to project; farther back from the disk and bring the grater-disk nearer to the front of the machine than the position in which the slicer works. The hub has an axle-bore, i3, in which, when the grat er is used, the main axle is seated, and in which it is rigidly secured by the thumb-screw 4:4, that screws onto or into it.

The gratter-disk is provided with burrs or teeth 45, which may be stamped in the stubpointed form shown in Fig. IX, or in the pointed form shown on the disk view in Fig. VI. The hurrs are projected in the direction that would best brace themselves in withstanding the force of contact with the material being grated. For this purpose they are made to rake or point forward in the line of the rotary movement ot' the disk. It will be seen that this disposition of the inclined angle of the burr, besides bracing it to the best advantage, also makes of the burr a guide-slide to direct and force the gratings through the aperture, from which they fall onto the inclined slide 8, which delivers them in the vessel placed at: its discharge-chute to receive them. This i'orm of burr is unich better adapted than is the common straight projecting-prong burr for withstanding the wear and tear of the work it has to perform, as it is individually a single strong burr, instead of, as is the common punched burr, a cluster of indefinite-shaped prongs that proj ect out from the body of the grater at about a right angle, and so at both a reverse angle to withstand the strain and have an inferior cutting and penetrating presentation to effect the grating; also, as it will be seen, thcsc burrs, which are machinestamped of the same regular shape and inclination, angle back toward their base, so as, besides in their Ainclined presentation, they thus also ln'ace themselves for the work they have to perform.

4U represents the gate or opening' in the front of the machine for the reception ott' the vegetables to he sliced or the material to be grated.

+l-7 is the chute at said opening, and 4H side pieces to the same.

til is an extensionplatform to the chute, which is pivotally secured thereto by metal hinge'-ln'ackets 50, that are secured to the ex tension-platl'orm by screws 5l or otherwise, and. have proj ecting lu or pivot-pins 52, that engage within the elongated slots 53 in the ends of the supply-chute and opening. An inclined pendent brace-ln'acket, 54, is secured by rivets or screws 55 to an gli-rbraclwts 5G, that are :fastened to the, under side of the extension-platform. A butt-ilange, 57, on the lower end of the brace-bracket rests against the front piece of the frame beneath the chute when the bracket acts as a brace. lVhen the vegetables to be sliced. or the material to be grated have been placed in the suppl y-chute, if the operator desires to use the extensionplatform as a follower to advance the material in the supply-chute to the rotary slieer or gratter, as the case `may be, and to lirmlyhold it while being' operated on, he places his thumb within the circlet 5S and grasps the bracket with his lingers, then raises the cone bined platform and follower, turning it on its pivotal connection 52 within the elong'atcd slot 553, and, as it forces forward the material, sliding along' said pivot-pin in the elongated slot until the slicing or grating is con'ipletcly effected, by which time the stopprojection 5) on the the outer end of the fol` lower comes in contact with the Vfront piece ofthe frame, wh ich prevents the Yfol lower from coming in contact with the slicer'or grater, as the case may be.

(5t) represents the bean-lmppcrs, preferably made of east or galvanized iron, which, as l; show it, is formed of a row of three sectional hoppers, til; but l do lnot confine myself to that number, for it may be varied to accord with the size ot' the maclline, &c. 'A bifurcated tongue, 52, is secured to the backcrosspiece of the hopper, and when the. hopper is placed in position at the sujjiply-opening wit-hinv the chute a pivoted latch-hook (ifi, that passes through the slot (ift between the prongs (35 ot' said bifurcated fork, and whose pivotal end is seated in the front of the frame above the supply-chute, is turned down,

IOO

and thus holds the upper end of the hopper in position. A cross-strap, (3G, secured to which are bows (57, is made, through its bows, to grasp the fron t of the sectional hopperand its vflanged ends G8, which are passed through the perforations G9 in the side pieces of the chute and hold the hopper below to its seat.

70 represents cogs around the periphery of the rotary disk of the slicer, which cogs engage with cogs 7l around the pinion-wheel 72, which is rigidly secured on a short thumbscrew shaft, 7 il, the screw-threaded end of which engages within the screw-threaded annular shaft 7l, that has its inner bearing, 75, near the top of the vfront casing of this frame. A knob, 7 U, at the opposite end of the screwshaft 7 23 serves to turn it into engagement with the annular shaft when the egg-beaterannex is set up. A liange-collar, 77, around the annular shaft holds the shaft to its right position longitiulinally and backs up the bevel pinion-wheel 7S, that is rigidly secured to it, so that it cannot slip its engagement with the bevel pinion-wheel 7), which is rigidly secured on the upper end of the vertical rotary shaft SO, that carries and works the egg-beater Sl. A bracket journal-box carrier, S2, secured to the front casing of the frame, incases and carries the double journal-box 823, which has a horizontal bearing, 8l, for the outer solid spindle end of the annular sha ft 74, where it projects beyond the bevel-pinion 7 S, that it carries, and also provides the vertical socket 85 for the upper end of the rotary shaft that carries the egg-beater. A second bracket, 80, secured lower down, also to the front of the frame-easing, provides the bearing 87 `for the egg-beater shaft.

The bracket 82, besides carrying the aforesaid double journal-box, also incases and carries a short conical-headed stud, SS, on which is pivoted a short strap, 89, that is furnished with a cap, 90, at its free end, which when turned round, so as to surmount the rotary egg-beater rod with its bevel-pinion 7 9, keeps it from working up out of engagement with the bevel-pinion 7 S. \Vhen it is desired to remove said rod after the detachment of the egg-beater, the strap Sil can be turned round, and the rotary sha-ft is then easily lifted out of its seat.

The egg-beater Sl may be of the common pear-shaped form of rotary egg-beaters, with steel bow-beaters 0l secured to a central stem, 92, at both ends of the bow, with a ronnd'footbutton, 93, at the bottom of the stem, so that if it should rest on the bottom of the bowl or other vessel that contains the and in which it works the but-ton will prevent the bows from friction against the bottom of the bowl; but the beater will work without the button touchingl the bowl, 'for the rot-ary shaft has bearings sufficiently apart from each other to insure the steady movement of the beater.

l do not confine myself to this especial form of beater. lt may be of any suitable construction that will effect its work in combination with my machine.

rlhere is asoeket, 94, formed in the enlarged upper end of the central stem of thebeater, of a size and 'form to tit as a sleeve around the lower end of the rotary shaft 80, and a collar, 05, surroumls the upper end of said socket. A milled-disk thumb-screw, 9G, turning in its screw-seat U7, contacts with the rotary shaft and rigidly fastens the egg-beater thereto.

US represents a (preferably sheet metal) partition casing ot' tin, galvanized iron, or other suitable material. The upper end of said casing is turned at a right angle, and when in position forms a horizontal cover, 99, that surmounts the slicing and grating devices. The vertical part of said partiti(n1-casing (when being placed in position) is rundown the vertical channel-grooves l0() in the inner sides of the end pieces until its lower end reaches the inclined slide 8. An elongated slot, lOl, is formed in the lower portion of the casingI to enable it to pass the main axle, which it does back of the shoulder 102 thereon. The said shoulder provides a rigid backin for the hubs that relatively carry the slicer and grater disks.

The partition-casingI consummates the iso lation of the slicing and `grating` chamber of the machine, so as to keep dust and dirt fromentering the chamber and contaminating` the material being operated on. It also prevents particles of the slieings and gratings from Hy ing back among the `gearin It will be seen, as shown and described, that the several parts of this machine are readily set up and taken apart, according to the varied work that it has to perform; and not only is it conformable to its change of work, but also the slicer-knives are easily adjusted to the thickness of the slices they are required tocut by varying the rake of their projected edges by the action of the thumb or set screws; also, thc pivoted extension-platform when it is elevated and slid forward, so as to become a follower, forces the material home to the aetion of the rotary slicer or `grate, as the case may be, and besides being more effectual than the operatons hands in effecting that purpose it also avoids alldanger of injury to his hands from their coming` in contact with the knives of the slicer of the `grater.

The egg-beater, being detachable at its sleeve-connection with the rotary shaft, as stated, (to which it is secured by a set-screw,) is a valuable feature, as it requires cleaning each time it is used.
