DAVID MAXVELL, OF ST. MARYS, CANADA, ASSIGNOR TO DAVID MAXWELL t SONS, OF SAME PLACE.

ROOT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 483,743, dated October 4, 1892. Application filed May 5, 1892. Serial No. 431,909. (No model.)

To aZZ whom it may concern: 1

Be it known that I, DAVID MAXWELL, manufacturer, residing at the town of St. Marys,in the eountyof Perth, in the Province of Ontario, Canada, have invented certain new and useful Improvements in RoocCutters, of which the following is the specification.

My invention relates to improv-ements in machines for slicing and pulping roots; and the object of the invention is to design amachine of this class which will by merely changing the direction of rotation either pulp or slice roots quickly and perfectly.

The invention consists in the construction hereinafter described, and particularly pointed out in the claims, and illustrated in the accompanying drawings, in which`A Figure l is a perspective View with the side of the machine removed, showing the knives arranged in the periphery of a drum. Fig. 2 is a view of amodiied form, showing my combined slicing and pulping knives arranged on the face of the wheel.

In the drawings like letters of reference iudicate corresponding parts in both figures.

A is the cylinder or the wheel upon which the knives are secured. The cylinder or wheel A is mounted on the shaft A in lthe frame of the machine and has central webs or arms A2, the hubs of which are secured to the shaft A. Said arms extend to and form a support for the cylinder.

L shows three knives B, with the intermediate spaces C.

D are elongated openings formed in the periphery of the drum or face of the disk, the intermediate spaces being connected together by the bridges E, to which the ends ot' the knives are secured. It will be noticed that the knives B are broad and V-shaped in crosssection and are provided with slicing-edges ZJ and pulping-edges h', which are composed of series of sharp teeth, as shown. The knives B are provided with strengthening or stiftening backs F and are secured to the end bridges E by the bolts f, which pass through the backs F and bridges E, as shown.

G is the hopper into which the roots are placed. It will be noticed in Fig. l that the inclined sides g g of the hopper G have pivoted midway between their ends the guidingbridge H, which is pivoted at the bottom and is cut away, as shown at 7L. The guidingplate Il is designed to be swung from one to theA other of the sides g and g as desiredaand when so swung rests on ledges 11 and t7,1espectively, made to the top of the perpendicular sides I and .I ofthe hopper. It will be noticed that the sides I and J and the inclined side gare in the form of gratings, as shown, so that the dirt may escape through the gratebars when the roots are being put into the hopper and during the period that the roots are being sliced or pulped against the sides I and J, respectively.

On reference to Fig. l it will be seen that when the cylinder is caused to revolve in the direction indicated by the arrow the swinging bridge H rests upon the ledge t', so as to form a guide for depositing the roots upon the cylinder, in order that the pulping-edges of the knives in coming around may act upon the roots in proximity to the side J, so as to pulp them, the pulp being forced through between the pulping-edges b int-o and through the opening D, from which it escapes from either side of the' central web into the receptacle provided to receive it. When the cylinder is caused to revolve in the opposite direction to that indicated by arrow, the guiding-bridge H is swung on its pivot so as to bring the free end against the ledge j on the top of the side J, the slicing-edges h of the knives being then designed to operate against the edge t', so as to slice the root-s. When the roots are sliced, they are forced beneath the edge and into and through the opening beneath the knives into the center ot the cylinder, from which the roots sliced are discharged from the end ot the cylinder into the receptacle.

In Fig. 2 it will be seen that the knives are arranged on the face of a disk or wheel and are supported on bridges before the openings in asimilar manner to that shownin Fig. 1. The roots fed into the hopper G are operated upon by the edges h to slice them when the wheel is revolved in the direction indicated by arrow and by the edge Z1 when the wheel is revolved in the opposite direction to that indicated by arrow in order to pulp the roots, which in sys IOO

both instances pass through the wheel and are delivered into a receptacle provided for the purpose.

I am aware that it is old toprovide a sliclng-knife to operate upon the roots when the wheel is revolved in one direction and a pulping-knife to operate upon the roots when the wheel is revolved in the opposite direction; but heretofore the slicing-knife and pulpingknife have been made separate and placed alternately in position on the wheel. In this method of construction the roots when vplaced in the hopper rest upon the knife, thereby holding the roots away from the surface of the Wheel and out of the circuit of the knife, so that the knives, being so close together, are prevented from ettectually operating upon the roots to slice or pulp them. By, however, providing the space between the knives and forming them as hereinbefore described the roots when deposited in the hopper are brought down to the surface of the wheel.

I nd in practice, on yaccount of the distance between the knives and the roots being brought directly against the surface of the wheel, that the knives act with much better results than in any machine for a similar purpose of which I am aware.

What I claim as my invention isl. In a combined root pulper and slicer, a wheel provided with a series of knives, each of which is provided with a slicing and a pulping edge, the knives being supported over elongated openings made in the working surface of the wheel and the slicing and pulping edges beingcontiguous and slightly above the side edges of the openings, as and for the purpose specified.

2. The Wheel A, having a series of knives B, V-shaped in cross-section, each of which is provided with a slicing-edge b and a toothed pulping-edge b and is supported over openings D by the end bridges E, to which the knife is secured by the bolts f, as and for the purpose specified. p

3. The wheel A, having a series of knives B, V-shaped in cross-section, each of which is provided with a slicing-edge?) and a toothed pulping-edge b', supported over opening D by the end bridges E, to which the knife is secured by the bolts f, and is provided with a stittening-back F, as and for the purpose specified.

4. The combination,with the wheel A, having a series of knives V-shaped in cross-section, each of which is provided with aslici'ng and a pulping edge b and b', supported on bridges E over the openings D, of the hopper G and grated sides I and J, as and for the purpose specitied.

5. The combinatiomwitli the wheel A, having a series ot knives V-shaped in cross-section, each of which is provided with a slicing and a pulping edge t) and b', supported on bridges E over an opening D, of the hopper Gr, grated sides I and J, and the guidingplate H, arranged as and for the purpose specied.

6. The combination, with a wheel A, having a series of knives V-shaped in cross-section, each of which is provided with a slicing and a pulping edge b and h', supported on bridges E over an opening D, of the hopper G, grated sides I and J, and the guiding-plate H, cut away ath, as and for the purpose specied.

7. The combination, with the wheel A, having a series of knives V-shaped in cross-section, with slicing and pulping edges b and b', supported on bridges E over the openings D, of the central web or arms A, secured to the shaft A and having an outer end of the arms extending behind the portion C of the wheel, as Vand for the purpose specified.
