HJ'ALMER NELSON, 015 DETROIT, MINNESOTA.
POTATO-SORTING MACHINE.
Application filed January 2, 1923. Serial No. 610,138.
To all cuhom it may concern:
Be it known that I, HJALMER A. TIELSON, a citizen of the United States, residing at Detroit, in the countyof Becker and State of Minnesota, have invented certain new and useful Improvements in Potato-Sorting Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a sorting device, and particularly to such a device adapted to sort fruits, vegetables and similar articles, the device being particularly designed for the sorting of potatoes. It is desirable to sort fruit and vegetables, such as potatoes, to separate the vegetables below a certain size, from the remainder before such vegetables are marketed. comprises a machine of the type in which the articles to be sorted are carried on a traveling belt or apron which is provided with apertures and which is given an agitatmg or undulat ng movement.
It is an ob ect of this invention to provide such a machine comprising a traveling retic- I ulate and articulated belt or apron having positively driven means at its ends for projecting and moving the same.
It is a further object of the invention to provide such an apron also having positively driven means intermediate its ends to give likereference characters refer to the same parts throughout the difierent views, and in which v Fig. 1 is a view in side elevation of the device; Fig. 2 is a top plan view of the device;
Fig. 3 is a vertical section taken on the line 33 of Fig. 2, as indicated by the arrows; 1 i i Fig. 4 isa plan view showinga part of the a'pronor belt on an enlarged scale;
The present device F ig. 5 is a vertical section on the line 55 ing devices; and
Fig. 7 is a vertical section on the line 77 of Fig. 6.
Referring to the drawings, the machine comprises a frame having four uprights 1, one at each corner thereof suitably braced and held together by cross members 2 adjacent its bottom and supporting at their upper ends longitudinal side members or boards 3. A trough-like hopper 4 is provided at one end of the frame above the side members 3 and has a sloping bottom discharging downwardly between said side members. Extending between and journaled in the side members 3 is a plurality of shafts 5, the ends of which project some distance outside of one of the side members 3 and these shafts have secured thereto on said projecting ends sprocket wheels 6. An endless chain 7 extends about the sprocket wheels on the end shafts 5 and the top run of this chain engages with the sprocket wheels on the other shafts 5 intermediate the end shafts. Boilers 8 are journaled on stub shafts secured in the side member 3 and these rollers bear upon the top of the top run of the chain 7 and hold the same in engagement with the sprocket 6. Another roller '9 is journaled on a short shaft secured in a bearing 10 bolted to the bottom side of the side member 3 and this roller 9 bears upon the top of the lower run of the chain 7 and maintains said chain in properly tensioned condition. The end shaft 5 remote from the hopper 4 is provided on the end opposite that carrying the sprocket, with a crank 11 which is turned to drive said chain and thus positively turn all of said sprockets. The
Supported upon the wheels 12 and disposed between the side members 3 is a belt or apron member 13, which member is of reticulate and articulated formation. Said belt is, as clearly shown in Fig. 3, supported on the wheels 12 and will be driven by the rotation. of these wheels by the shafts 7 and apertures in the adjacent strip so as to be pivotally connected to said strip and said tongues are connected substantially in aline- 20' ment with the central axis of the openings or recesses 16. The rear edges of the apertures through which said tongues are connected are bent or folded rearwardly, as shown at 19 in Fig. 5 so as to form arounded surface for the connection of the bent end of the tongues 18. When the members 14 and 15 are thus connected it will readily be seen that the recesses 16 in one strip aline with the recesses 17 in the adjacent strip to form one opening through the belt or apron. It will also be seenthat there are a greater number of recesses 16 in the strips 14 than in the strips 15 and the strips 15 thus .l-ia-vea comparatively wide imperforate portion at their ends so that the end edges of all of the strips are substantially in .alinement and the apron thus has: substantially straight parallel sides. It will also be noted that the recesses 1'6 and 17 as illustrated, are made substantially-on the arcof a circle, the recesses 16 having their sides prolonged in parallel relation.
In operatiomthe articles or potatoes to be sorted are placed in the hopper 4 and pass downwardly onto the apron 13 which will be given motion by means of the crank 11. The apron willbe-positively pulled along by both the wheels 12 at its'ends andto more or less extentby the wheels 12 intermediate its ends.
At the same time, the belt will be given an agitated or undulating motion due to the spaced'arms of the wheels 12. It should be particularlynoted that all of the wheels 12 and shafts 5 are positively driven so that a i adhered tothe potatoes. This dirt will be removed as the potatoes roll about on the apron. Owing to the fact that the potatoes are moving on'substantially a fiat surface, the same will-not bebruised or marred. The
potatoes passing through the apron or belt 18 will be collected and directed to the desired point by any suitable means.
From the above description it is seen that applicant has provided a simple and improved form of grader. By positively driving each of the wheels 12, a great strain is not placed upon such wheels at one end of the belt which has been a serious objection to graders of the prior art. Furthermore, a positive agitation and movement of the belt is insured as there is no chance for some of the wheels to stick and the belt to be pulled thereover. The apron 13 is preferably made of sheet material and the corners of the recesses will be suitably formed so that no injury can occur to the potatoes. The belt 13 and the entire machine is easily constructed, strong and durable and when once assembled will operate continuously with practically no attention necessary for maintenance or repairs.
It will, of course be understood that various changes may be made in the form, details and arrangement of the parts without departing from the scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.
