A mushroom trimming machine embodying my in vention includes a suitable support or bed plate 10 which fixedly supports a sleeve 12 which is preferably lined with a .bushing 14. A hub 16 is rigidly secured to sleeve 12 and has rigidly secured thereto a lower supporting plate 18 which will'hereinafter be further referred to. The upper edge of hub '16 co-acts with the upper edge of sleeve '12 to support a bearing plate 20 which rotatably supports hub 22. Hub 22 rigidly carries a relatively heavy upper plate 24 which in turn, also rigidly supports and makes unduly frequent cleaning necessary. 1
come'in contact with the mushrooms are lined, or coated,
with a n'on-wettable material, such as Teflon or with one of a number of available silicone preparations, so as to minimize the adherence of moisture anddirt to said A further object is to produce an improved machine of the type set forth which is adapted for processing mushrooms of different sizes "without the necessity of making any adjustment to any part of the machine.
A; still further object is to produce an improved ma chine in which the manual feeding of the mushroom is expedited and facilitated.
'A still further object is to produce an improved machine of the type set forth which can be used for trimming on the roots ofthe mushrooms only, or for both trimming'the roots and for severingthe stems from'the caps'of the mushrooms. i

These and other objects are attained by my invention as; set forth in the following specification and as illustrated in the accompanying drawings in which:
Fig. 1 is a top plan view of a machine embodying the invention, certain parts being broken away to show details of construction.
Fig. 2 is an enlarged section on line 2-2 on Fig. '1.

a top cover plate 26. Hub 22 is keyed as at 28 to a shaft 30, the lower end of which is secured at 32 to a hub 34 which is secured to, or forms part of, a gear 36. Gear 36 is rotated at the desired speed by a pinion 38 which forms part of a gear reduction train 40 which is actuated by a motor M. To the periphery of cover plate 26 is secured a circular'pendent apron 27, which will be hereinafter referred to. By this arrangement, when motor M is energized, plates 24 and 26 and apron 27 will be rotated as a unit, and at the desired speed, in the direction of the arrow, as viewed in Fig. 1.
As best shown in Fig. 1, the machine includes a number of units 41 to 50 inclusive, each of which is adapted to receive a mushroom and is operable to trim only the root of the mushroom or to trim the root and to sever the stem from the cap of the mushroom. As best shown in Figs. 2 and 5, each unit includes a yoke which is rigidly secured to the underside of cover plate 26 and to which are rigidly secured an inner plate 52 and an outer plate 54, which serve as hangers for the remaining parts, as best shown in the left hand portion of Fig. 2. Hanger plates 52 and 54 have horizontally registering holes therein through which rods 56 are freely movable. The
inner end of each rod 56 is connected, by any suitable 60 are so arranged as constantly to bias their respective rods 56 radially outwardly as viewed in Fig. 1. To the outer end of each rod'56 is rim'dly secured a curved shoe 66 which serves as a pusher as hereinafter set forth. Also passing through other horizontally registering holes in each pair of plates 52 and 54 is a rod 68, the outer end of which carries a V-shaped receptacle which is made of two walls secured together to form an acute angle, as clearly shown in Figs. 7 and 8. The upper, open ends of the receptacles 70 of units 41 to 50 register with corresponding access openings 71 which are formed in the periphery of upper cover plate 26 and through which a mushroom may be conveniently laid horizontally in the like, to stub shaft 76 which carries a roller 78.
Each rod 56 also carries a stub shaft 84 which carries a freely rotating roller 86 which is constantly biased by the corresponding spring 60 radially outwardly or into contact with a cam 90, which is rigidly carried by plate 18. The shape of cam 90 is best shown in Fig. 1 and it will be further referred to. i r
Bed plate also rigidly carries an'arm 94 which ries an arcuate bar 96 which is disposed above a portion of the path of rotation of cover plate 26 and apron 27 and carries a pendent knife 98 for trimming the root 99' of the mushroom and knife 100 for severing the stem 101 of the mushroom from the cap 102 thereof. The working surface of cam 90 includes a first portion which ex tends from point A to point B, a second portion which extends from point B to point C and a third portion which extends from point D to point A. The cam is interrupted to form a gap between points C and D. The working surface of cam portion A-B is circular, and is nearer to the axis of rotation shaft 30 than the portions B--C and D--A. The working surface of the second cam portion is non-circular and, having reference to' the direction of rotation, it slants progressively radially outwardly from point B to point C. The working surface of the third portion of the cam is also noncircular and, having reference to the direction of rotation, it slants progressive ly radial-1y inwardly from point D to point A. By this arrangement, when rollers 86 travel over portion A- B of the cam, they are in their maximum inward position and so are their corresponding pushers 66,. as shownby units 41, 42, 43- and 44 in Fig. 1. As rollers 86 move over cam portion B-C, they move progressively radially outwardly, and their corresponding. pushers 66 pr'ogres-* sively push the mushroom outwardly to cause the stems of the mushrooms to project through openings 106 and 108, as shown by unit 45 in Fig. 1. moves into gap C--D, it will be wholly free of the re straining action of cam 90 and it is moved radially out wardly to the position shown in Figs. 2 and 4 in which As each roller 86* it and the apron.
pressure of knife 100. In order to avoid this, I provide cutting supports 104, one for each of units 41 to 50, each of said supports having an opening 106 therein which registers with opening 108 in apron 27. As will be seen from Figs. 2, 4 and 10, each support 104 is spaced enough from the corresponding portion of apron 27 enough to permit free movement of knife 100 between By this arrangement, the mushroom stem is supported by the edge of opening 106 and by the edge of opening 108 and will not break while it is being severed by knife 100.
At least the parts of the apparatus which come in contact with the mushrooms are made of, or ar'liiie'd, of are coated, with a non-wettabl'e, or non-adhering, material, such as Teflon or with one or another of the available silicone preparations so as to discourage the deposit of dirt thereon and so as to be more easily cleaned.
In order to adapt the machine to cutting only the roots 99 of the mushrooms, I provide holes 110 which extend through supporting plate 24 and cover plate 26 and I when the rods are in their innermost position,- register with holes 110. When it is desired to prevent pushers-.66
the stern 101 of the mushroom projects outwardly through openings 1'06 and- 108 and the head 102 of the mush room abuts the edges of V-shaped opening 108 in apron 27, as best shown by unit 46 in Fig. 1. Continuedgrotation causes stem 101 of the mushroom to be severed by knife 100 as shown in Fig. 10. After passing knife 100; the roller 86 of each unit rides on portion D-A of cam 90 progressively to retract its corresponding pusher 66 as indicated by units 46, 48, 49 and 50 in Fig. 1.
It will be noted that, throughout the operation heretofore described, roller 78' was riding on: track 80. How ever, when a unit has passed the position of unit 46; in Fig. 1, its corresponding roller 78 falls off track 80' anddrops through opening 82, or from the broken, to the solid, line position of Fig. 8. This causesreceptacle 70 to tilt and drop the head 102 of the mushroom as bestillustrated in Fig. 8. Immediately after this takes place, roller 78 against travels on track 80 and restores recep-- tacle 70 to its mushroom receiving position. By the time this takes place, roller 86 will have reached pointA on the cam and its corresponding pusher will have been retracted to its extreme inward position. make sure that receptacle 70 is in its proper mushroom receiving position, mushrooms are not deposited in the receptacles until each unit has reached the' position of unit 41*. Since the positions of. units 42 and 43' are the In order to from acting on mushrooms in receptacles 70, pins"11.4 are inserted through holes and 112, thus locking'ro'ds 56 and pushers 66 in their innermost retracted positions the edges of openings 106 and 108 and, therefore, itwil not break while the root 99 is being severed.
