Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed June 22, 1914. Serial No. 846,668.

T all whom it may concern:

Be it known that 1, CHARLES 0.1. Nnisson, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented cer- Another and more snecific object is to provide a beet harvester which comprises a" wheel supported frame carrying means to dig and'elevate the beet to a point where the tops aresevered therefrom; also means for topping the beets.

Another object of my invention is to provide elevating means that are adjustable in as to be suited for operation in connection with beets of different sizes.

Another object is to provide novel gearing means for operating the elevating means that are adjustable so as not to be interfered with when the elevating means are adjusted and the proper elevating of the beets at the proper time is insured.

Another object of importance is to provide a beet harvester of the character described that is of exceedingly simple construction and is light, strong and. durable, may be cheaply manufactured and is inexpensive to maintain in working condition.

The above and additional objects are accomplished by such .means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out as claimed.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to, practice, and throughout the several views of which similar reference numerals, designate corresponding parts:

-Figure 1 is a longitudinal sectional view partly in elevation of my improved. beet harvester, showing the same in assembled and operative position. Fig. 2 is a top plan detail sectional view of the gearing to operate the elevating means. Fig. 4c is a fragmentary detail sectional view of the adjusting. gearing at the upper ends of the elevator bars. Fig. 5 is a transverse sectional view taken on' the plane of line 5-5 of Fig. 1, illustrating the means for operating the topping knife and showing parts of theelevatingmechanism. Fig. 6 is a transverse sectional view taken at the forward end of the harvester, showing the means for loosening the soil about the beets so that they may be readily pulled from the rows by the tops. Referring to the drawings by characters entirety the vehicle'body or frame having mounted ad acent its ends, front and rear axles 2 and 3 respectively that. have wheels 4: on their ends. Suitable draft gear desig- I nated 5 as an entirety is operatively connected with the platform or frame 1. A drivers seat 5 of the usual type is mounted on the frame 1. p

The frame 1 consists of two parts, a rear part A and forward part B. The part B carries all of the mechanism except the receptacle to contain the topped beets so that the device may be turned at the end of a row as will be later more fully described. A'n angular bearing C is secured adjacent the forward edge of the rear part A and pivoted by means of a bolt D to the rear part of the frame .B as clearly shown in Fig. 1 in v the drawings. A block E spaces the bearing C from the frame part B so that free turning of the part B relative to the frame part A is provided.

Mounted on the frame 1 and .extending upwardly and rearwardly therefrom are spaced and parallel elevator bars 6 and 7 that are supported intermediate and apdles 10 fixed on their outer ends. The lower ends of the rods 8 are grooved circumferentially, as at 11, and positioned within angularly disposed sockets 12, that are slidably supported on the frame 1 by means of angle guides 12 that are secured by suitable fastening means to the frame and engage the upper faces of the flanges 12 that act as bases for the sockets. A holding screw or bolt 13 is inserted through the intermediate portion of each socket and at its inner end engages within the groove 11 in the rods 8. It will be readily seen that the bars 6' and 7 of reference the numeral 1 designates as an may be adjusted in an approximately ver-I tical plane so that the lower ends thereof are spaced in inoperative relation to the ground.

. The bars .6 and 7 are also supported at points adjacent to the rods 8 but slightly spaced and arranged rearwardly therefromon a horizontal adjusting rod 14} This rod .14 is adjustable in a pivoted link bracket 15 that is pivotally secured to an upstand ing support 15v carried by the frame 1. A

receptacle 16 is .mounted on the body to catch the beets that are'topped. A handle 17 is fixed on one end of the adjusting rod "curved upwardly and outwardly, as at 18,

. gripped .at the topjand pulled' from the- 14: topermitadjustment of thebars 6 and7 laterally onto and, from each other. It will be readily seen'that' the rod 14 acts as a pivot and that in operatinglth'e adjusting rods 8 the forward endsof-the bars 6 and 7 will be lifted upwardly.

The forward ends of the. bars and 7 are so a' sjto slide over the surface of the ground; Slightly" curved and elongated fingers '19 are arranged at the extreme forward end of the bars 6 an'd.7 and extend outwardly in a slightly convergent plane and aredesigned .tofsli'de over the ground on opposite sides of a rowof beets so as to clear the beets; that are to be gathered and elevated to theltoppingfknives, of "trash 'and other foreign matter. As almeans for loosening the beets in the rowsso that they may be readily ground I provide digging fingers 20'that are. curved inwardly toward one another at I theirlower ends, as at 21, and secured upon the inner faces of'the bars6 and. 7 adjacent tothe lower ends of .said bars. Fingers 20 are slidable in suitableibrackets 22secured upon the inner faces of the bars 6 and 7 and areadjustable so as to dig into the ground tend the chains 29 in close proximity to one elevating mechanism comprises 51 plurality of sprockets 27 that are j'ournaled for rotation in transverse recesses 28 formed ,in .the bars 6 and 7. The sprockets that are arranged at the ends and centralfportio'ns of the bars 6 and ,7 have mounted thereon elevating chains 29 and are so disposed at their inner sides as to gripori clamp the tops of the beets therebetween sufHcientIy to hold the beets and elevate them to the topping mechanism, to be later described. The sprockets27 are of such. sizeas to exanother on certain sides of the chain \Z 5'. feet the action described.

The centrally arranged sprockets 27 on the bars 6 and 7 are splined on substantially upright shafts 30 that are mounted in the bars 6 and 7. These shafts 30 extend downwardly below, the under faces of the bars 6 and 7 and are slidable with relation there? to, the upper end of each shaft being arranged so as to prevent its pulling out of the. bars. Keyed onjthe lower end of the shaft 30 is a bevel gear 3lthat meshes with the bevel gear; 32 which is spline'd on a' horizontal shaft 33. The horizontal" shaft 33 is arranged in supe'fposed parallel relation to the forward axle2 of the device and is provided at its outer end with a pinion 34 keyed thereon and which meshes'with a largerge'ar 35 mounted ontheaxle 2. The

shaft 33 is journaled; in suitable bearing or platfornf 1, and is also supported by means of an angular arm 37 that on its lower end is operatively connected with a cylindrical extension'38 which is formed in-' tegral with the gear 32'; The projection 38 is provided with a key groove to receive the keys on-the shafts so that the gear 32 is brackets 36. that are'secured to the frame splined and is slidable horizontallyv on'the shaft. The upper end of'the arm'37 is provided with a pin and slot connection designatedjig asan entirety with the outer side faces of the bars 6' and 7. v The pin. and slot connection 39 permits the vertical 'or approximately vertical adjustment ofathe bars 6"and 7, The lateral adjustment of the bars 6 and 7 will not interferewith the operating mechanism for the elevator chains :29 inasmutt as the gear 321s slidable upon its shaft and is connectedby the 37 with the bars 6 and 7. Thus the gear 32 is caused to-slide in accordance with-themovement of the gear 31 and held in meshingrelation at all times. Brackets 121 described in con- .nection with the sockets 12 for the adjusting rods 8 slidably secure the socket and adjusting rod. It willthus be seen that the adjusting rods 8 are permitted "lateral adjust:

is thus notinterfered with. I, clutch collar {l0 is sp'lined 'onl 'the front axle 2 and arranged to cooperate with a clutch collar 41 that is mounted on; the shaft 2'fan'd' secured tdth' large gear 35. ;It will be readily. seen that when the'gears and clutch members 40'and41are not engaged the mechanism for elevating the beets will be in inoperative position. To cause. the clutch members 40 and 41 to coiiperate I proment and the lateral adjustment of the bars vide the operating levers 42 for the clutch memberslO that are provided with forked lower ends fitting withingrooves insuch clutch members. The. operating levers 42 may be suitably connected with the frame and approximatelyarranged adjacent to .the drivers seat so. that the driver by grasping one of the levers 42 may cause the clutch ping knife 43 that has a number of angu-- larly disposed blades extending radially from the center of the knife and is fixed upon the lower end portion of the vertical shaft 44. The shaft 44 is 'rotatably journaled at its outer end to a slidebar 45 that is arranged transversely of and slidably secured to the bars 6 and 7 at its end. The end portions of the bar 45 are slotted, as at 46, and receive loosely, fastening means to permit sliding of the bar 45. A gear 47 is keyed upon the lower end cf the shaft 44 and meshes with the gear 48 that is keyed upon the lower end of the shaft 49 on which a certain sprocket 27 is mounted. In this connection it will be noted that the shaft sprocket is arranged between the center sprocket and upper sprocket and adjacent to the topping knife 43.. The rotation of the knife 43 is brought about through the me dium of the shaft 49 and gears 48 and 47 The operation of my device. may be briefly described as follows: Assuming that the device is ready to be drawn along a row of beets, the operator upon manipulation of the rod 42, causes the clutch members 40 and had. The digging fingers 20 are arranged I provide at the upper end of each bar a slidable member 50 that is slidable within a recess in which the upper sprocket is mount ed. The member 50 is connected with the sprocket andan adjusting screw 51 that is turned in the outer end of the bar and swiveled at its inner end to the member 50. By operating the adjusting screw the slack of the chain may be regulated. It willbe noted that when it is desired to lift the digging fingers 20 and cooperating parts in spaced relation to the ground the handles 10 are grasped and the adjusting rod 8 rotated. Upon the rotation of the adjusting rod 8 the bars 6 and 7 will be moved on the bar 14 upwardly so that the lower ends thereof are spaced from the ground and the device may be readily drawn across the field when not operating. p

3 In practice, I have found that the form of my. invention, illustrated in the drawings and referred to-in the above description, as

the preferred embodiment, is the most efii cient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to at the desired position and loosen the earth along opposite sides of the beets as the bar-1 vester is drawn along the row. The'extend v ed fingers 19 serve to clear the space about the beets of trash and other foreign matter between the lower ends of the bars 6 and 7 and will be engaged and clamped by the chains 29. .The chains 29 and lowermost sprocket 27 are so arranged that the beets or. tops thereof will be readily grasped at points above where the tops are'joined to the beets. The spacing-of the chains 29 relative to each other is regulated by the adjustment permitted the bars 6 and 7. It will be readily seen that this chain is adjustable drops into a receptacle 16 mounted on the platform 1 that is disposed immediately beneath the topping knife. The top is carried up toward the end of the bars and drops rearwardly of the device upon the emphasize the fact that various minor changes in details of 'construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as. set forth.

Having thus described the invention what is. claimed as new, is: I
