Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, DAVID MARSHALL, manufacturer, of the city of Hamilton, in the county of Wentworth, in the Province of Ontarlo, Canada, have invented certain new and useful Improvements in Tomato-Peeling Maghines, of which the following is a specificaion.

My invention relates to improvements in tomato-peeling machines, and the object of the invention is to provide a simple and cheap device which will peel the skin and remove the core from the tomato; and it consists, essentially, of a shaft mounted on suitable standards, a wheel secured to the shaft, a series of plates secured'to the wheel and forming a drum and having openings therein provided with radial prongs and a diametric bridge having a central coring-ring, a pair of pulleys secured to a suitablestandard, a belt in the pulley designed to press against the periphery of the drum over the annular openings, a central pressure-roller designed to press the belt against the drum, and a strippingknife suitably supported and held against the inner periphery of the drum, the arts being arranged and constructed in deta' as hereinafter more particularly explained. Figure 1 is a perspective view of my machine. Fig. 2 is a detail view of one of the stripping and coring plates attached to a portion of the supporting-wheel. Fig. 3 is a detail cross-sectional view of one of the plates with the bridge and core-separator. Fig. 4 is a plan view of the arts shown in Fig. 3.

In the drawings lil e letters of reference indicate corresponding parts in each figure.

A is the supporting-frame.

1 Bbis the driving-shaft, provided with a pul- 0 is a wheel secured on the shaft B, and C represents plates secured to the ring or wheel by bolts 0.

C is an openin formed in each plate, provided with radia y-arranged portions 0 extending in proximity to the center of the opening.

D is a diametrically-arranged bridge having a central annular ring (1. The ring and the bridge are provided with sharpened outer edges, as shown, Fig. 2.

E is a standard secured to the main frame A, having arms e e.

E and E are idler-pulleys supported on studs 6 in proximity to the periphery of the drum formed by the plates C F is an endless belt extending around the pulleys E and. E and designed to press against the periphery of the drum in alinement with the openings C.

F is a roller located intermediate of the length of the belt and desi ned to press the belt against the drum and help to force the tomato through the openings in the plates. This roller is supported on an arm of the standard E.

G is a knife for severing the body of the tomato from the skin after the major portion of the skin has been taken from the tomato.

Having described the principal parts involved in my invention, I shall briefly describe the operation of the same. A rotary movement is given to the wheel C through the driving-pulley b and shaft B. The tomatoes are fed onto the revolving plates C by a suitable feeding device and brought centrally onto the prongs c in the opening C and are carried under the belt F, which presses the tomato through the openings. The skin of the tomato is thereby torn off by the prongs and the-parts of the tomato separated at the center by the core-ring d. The knife G completes the separation of the tomato from the skin. The skin is carried outside the wheel to a suitable receptacle and the tomatoes also drop into a separate suitable receptacle.

From this description it will be seen that I have provided a very simple machine by which the tomatoes are thoroughly peeled and the core is cut out for canning purposes. The drum, it will be noticed, has its spokes arranged to one side, so that the drum provides an overhanging rim which is free and unobstructed so far as the space within it is concerned, and into this space the cutter G projects, the said cutter being supported on one side of the drum upon the standard E.

What I claim as my invention is 1. In combination, in a tomato-peeling machine, a rotary drum having its periphery provided with openings through which the tomatoes are to be pressed, the said periphery overhanging the drum at one side and leaving an unobstructed space within it, means for pressing the tomato upon the periphery of the drum and cutting means extendin into the unobstructed space, substantia y as described.

2. In combination in a tomato-peeling machine, a frame a rotary drum having its supporting-spokes arranged near one edge there of whereby its periphery overhangs an unob structed space, said periphery having openings therein, a support extending up from the frame to one side of the drum, a band arranged over the drum for pressing the tomato through the openings, pulleys about which the band passes, said pulleys being carried by the support and a knife also carried by the support, said knife extending into the unobstructed space within the periphery of the drum, substantially as described.

3. A tomato-peeling machine comprising a rotatable Wheel suitably supported and driven, a series of plates secured to the Wheel and having annular openings therein provided with radially and inwardly extending V-shaped prongs with a central opening between the free ends of the prongs and with means for cutting the cores from the tomatoes and means for forcing the tomatoes through the openings as and for the purpose specified.

4. In a device of the class described, a plate having an annular opening provided with radially-arranged and inwardly-extending prongs, and a diametrically located bridge having a central annular opening having upper sharpened edges, said prongs being of such a length as to leave a space between their inner ends and the said edges, as and for the purpose specified.

5. In a device of the class described, the combination of a drum provided with a series of arc-shaped plates secured thereto in proximity to each other and each having an opening therein provided with radially-arranged and inwardly-extending prongs, and a bridge and central ring sharpened on its upper edge, said ring being located within the opening formed by the inner ends of the prongs at a distance from said ends, and means for forcing the tomato through the opening as and for the purpose specified.

6. In a device of the class described, the combination of a drum provided with a series of arc-shaped plates secured thereto in proximity to each other and each having an opening therein provided with radially-arranged and inwardly-extending prongs, and a bridge and central ring sharpened on its upper ed e means for forcing the tomato through the opening, and a knife suitably supported and projecting under the plates as and for the purpose specified.

DAVID MARSHALL.
