l SPECIFICATION forming part of Letters Patent No. 763,571, dated June 28, 1904.

Application iiled May 1l, 1903. Serial No. 156,684. (No model.)

To all whom it may concern.

Be it known thatwe, CHARLES H. SMITH and FRANK D. GIDDINGS, citizens of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented a new and useful Beet Lifter and Topper, of which the following is a specification.

This invention relates to beet lifters and toppers; and it has for its object to provide a machine of this class which shall possess su-jperior advantages in point of simplicity, durability, ease/and eonvenienceof operation, and general efficiency. Y

Our invention may be generally described as consisting of a wheel-supported frame having connected therewith a pair 'of beams supporting a single plow, the latter being in the nature of an zinclined plane which is adapted to raise or lift the beets. Endless chains are provided which seize the topsof the beets andcarry the same in a rearward direction within the range of inuence ofa rotary knife or cutter, whereby the beets severed from the tops are deposited upon the ground conveniently for gathering, While the tops are` dis- Means'are provided for guiding the carrying-chains, for adjusting and regulating the gathering mechanism, and for lowering or raising the beams.

carrying the plow as may be desired or necessary. i

In addition to these general features the invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, and par- I ticularly'pointedout in the claims.

`In the accompanying drawings, Figure l is a perspective' view of our improved beet lifter and topper. Fig. 2 is a top plan view of the same,-the front end, including the draft attachment and the front supporting-wheels,

' porting device and the tongue-supporting bolt.

Fig. 7 is a perspective detail view showing one of the chain-tightening devices for the.

endless carrier with the parts separated. Fig. 8 is a perspective detail view of one link of one of the endless carriers. Fig. 9 is a side elevation illustrating a modification.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The main framel of the device is composed of parallel side pieces 2 2, connected at their vand forward ends of which `are curved inwardly inthe direction of each other, as shown at 9, and are atten'ed., so as to form suitable lsupports for the vplow l0, which is boltedl The plow, as already stated, prac.

thereon. tically forms an inclinedA plane adapted to dig into the ground under the beet-.roots and to lift the latter gradually to the desired elevation, lifting at the same time such dirt as may adhere to the roots. In the preferred form of the invention the plow-blade 10 is provided with a plurality of rearwardly-extendingrngers 11, bolted orotherwise suitably secured to the under side of its rear end, said lingers serving to support the beets as they pass from the plow and to permit the adhering dirt to be separatedtherefrom.

The plow-beams are connected pivotally with the front ends of the converging side pieces 4 of the frame by means of bolts 12, the front ends of the plow-beams being extended for some distance-say about twentyfour inches-in front of said' pivotal connection. The extreme front ends of the plow-beams are connected and spaced by means of a brace 13, having upturned ends 14, which are pivotally connected with the front ends of the plowfront supporting-wheels 24 are journaled.

beams by means of single bolts 15, upon which the connecting and spacing piece or brace 13 is thus permitted to swing. rlhe front ends of the plow-beams are,furthermore, connected by means of a horizontally -disposed brace 16, having lugs or ears 17, whereby it is connected by means of bolts 18 with the outer sides of the plow-beams. The brace 16, which is provided with a plurality o f perforations 19, is for the attachment of the draft, a clevis 2O being provided for this purpose.

The pivoted brace 13is centrally perforated for the passage of a shank or shaft 21, the lower end of which carries an axle 22. The outer ends of the latter are bentor tilted downwardly and form spindles 23, upon which the It will be seen that these front supporting-wheels are downwardly inclined in the direction of each other and that they travel on opposite sides ofthe row of beets that is to be operated upon. Thus by the downward pressure exerted by said wheels the tendency will beto loosen the beets in the ground,therebylightening the work of the plow or lifter and correspondingly lightening the draft upon the machine. By this construction, which will admit of the wheels swinging under the front part of the frame, a short turn may also be made whenever desired. The upper end of the shaft or shank 21 supports the tongue 25, which is preferably provided at its rear end with a clip 26, terminating in a collar 27, engaging the shank 21 and provided with a set-screw 28 or other suitable means whereby a solid attachment may be effected.

The rear part of the frame is supported by means of traction-wheels 29, thehubs of which are to be provided with automatically-operating clutch means 30 to facilitate the backing and the turning of the machine. The wheels 29 are mounted upon the ends of an axle 31, which is journaled in boxes 32, the latter being suitably secured upon the under sides of the parallel side pieces of the main frame. The latter is provided at opposite sides with uprights 33, affording bearings for a rockshaft 34, which is provided at one end with a hand-lever 35, carrying a spring-actuated dog or pawl 36, which engages a segmental rack 37, which is suitably attached to one of the side pieces of the main frame and which, as shown in the drawings,'may be associated with one of the uprights 33. The rock-shaft 34 is provided with radially-extending arms 38, which are connected, by means of links 39, with the plow-beams 7. rlhe latter and the parts related thereto may thus be vertically adjusted by means of the hand-lever 35 which, as will be seen, is within convenient reach of the driver, whose seat 40 is supported upon the standard 6.

The bolts 12, which -form the pivotal con-` serve for the attachment of a pair of heavy iron straps 41, each of which is provided with a plurality of perforations 42 in order that Vertical adjustment of said straps may be readily effected. Projecting rearwardly from the straps 41 are a pair of supporting-arms 43, which latter may be formed integrally with or suitably connected with said straps 41. The supporting-straps 43 are extended rearwardly between the plow-standards, and their rear ends are connected, by means of bolts 44, with an ox-bow frame 45, the sides of which have perforations 46 to admit of the proper adjustment of the rear ends of the supporting-arms 43. Suitably attached to the latter near their front ends are a pair of rearwardlyextending downwardly curved fingers 47, which as the machine progresses serve to engage and elevate the beet-tops and to convey them into the path of engaging elements to be hereinafter described.

48 designates a bolt the head of which is in engagement with a clip 49, suitably secured to the top of the ox-bow frame 45,-from which said bolt thus vextends in an upward direction. A pair of arms 50, which are firmly secured, by means of clips 51, to the inner sides of the plow-beams, are extended upwardly and rearwardly from the latter, converging to form a tubular sleeve 52, through which the upper end of the bolt 48 extends. Upon said bolt, between the sleeve 52 and the clip 49, is coiled a spring 53, a washer 54 being interposed between the upper end of said spring and the sleeve 52. Above the said sleeve the bolt 48 is provided with a tightening-nut 55,Whereby the tension of the spring may be regulated. It will be readily understood that the rear ends of the supporting-arms 43 are supported, by means of the frame 45 and bolt 48, from the arms 50, which are firmly clipped to the plow-beams.

Suitably bolted, clipped, or otherwise secured to the supporting-arms 43 at a suitable distance in front of the ox-bow frame 45 is a frame composed, essentially, of side pieces 56, connected at their upper ends by a cross-piece 57, supporting a bearing-frame 58. The latter frame affords bearings for a counter-shaft 59, carrying a sprocket-wheel 60, which is connected, by means of a chain 61, with a sprocket-wheel 62 upon the axle 31 of the machine. The sprocket-wheel 62 is normally loose upon the axle, and it has an annularlygrooved hub or collar 63 engaging a forked lever 64, which may be fulcrumed to an upright or standard 65, suitably supported by the main frame and capable of throwing the said sprocket-wheel into or out of engagement with a clutch 65, which is mounted securely upon the axle. A segmental ratchet, as 66, or any other suitable means may be provided for the purpose of retaining the lever 64 in such position as to retain the sprocket-wheel either in or out of engage- IOO IIO

'ment with the clutch. It is obvious that when the sprocket-wheel 62 is in engagement with 'the clutch rotary motion will be transmitted 'from the axle of the machine and said sprocket-wheel to the parts operated by thev latter,l as will be presently more fully set, forth. A j

The ends of the top pieces 57 are extendedY beyond the uprights 56, so as to afford bearings for vertically-disposed shafts 67, for the lower ends of which suitable bearings are provided. Thefupperends of the shaft 67 are provided with bevel-pinions 68, meshing with,

'bevel-gears 69 and 70 upon the counter-shaft 59. One oi' the bevel-gears, 70, in addition` to the cogs upon vits outer side, which mesh v with the corresponding pinion 68, is provided" the purpose of severing the tops of the beets.

on its inner side with cogs 71, meshing with a pinion 7 2 upon the front end of a rearwardlyextending shaft 7 3, suitable bearings for which' are provided inthe frame of the machine, the rear bearings being formed upon the inside of one of vtheside pieces of the o'x-bow frame 45,..the shaft 7 3 being extended a short dis. tance in rear of the latter frame and beingv there provided with a bevel-gear 74. Addi`,

tional bearings are provided for a verticallydisposed shaft 75, carrying at its lower end'af horizontally-disposed cutter 76, provided with a plurality of curved radiating blades 77, for

78 78 designate a` pair oi' shields, preferably constructed of heavy sheet metal and secured, bymeans of bolts, rivets, or othersuitable means, with the vlower ends of the frame-barsA 56 and the sides of the oxY bow frame 45, the sides of the latter being converged inthe direction ot' eachother, as will be understood.

` It is obvious that the rear ends of the shields 78 approach each other much more closely than at'their front ends. Said shields are pros` i videdat their lower' edges with outwardly extending ianges 79, and to their inner sides,

near the lower edges, are bolted flange-bars 80, which are for the purpose of supporting. the conveyer-chains. The. front ends of the latter, which are designated 81, are mounted upon sprockets 82 near the lower ends of the shafts 67, .and the rear ends oi' the said chains are mounted upon sprocket-wheels 83, one of which is journaled upon a stub 84, projecting be preferred.

` sprocket-wheels have been shown," ,Inis evident that by moving the extensions 88 out Awardly upon the yflange-supported'arms 87 V may be adjusted to impart to said chains any"y desired degree of tension. 1. i

Alternate links of the conveyer-.chains 8 1 are provided with outwardly-.extending lin' gers 91, the ngers ofthe two-.chains inter-f i meshing, so that they will-seize upon yand firmly hold the topsof thebeets' asthe latter` are being brought within the path-orrange of g operation of said chains. The latter willsservfe to carrythe beets rearwardly inthe path ef the rotary cutter, whereby the tops are severed,,

the beets permitted to drop upon the' ground;-

and the tops as they emerge from between the J inner or coacting leads of the chain .are -en-V gaged by a curved rodv 92, whereby they are thrown to one side of. the'row of beets,1-so that` the latter may be subsequently convenientlyr For the ypurpose of keeping the main drivf` ing-chain taut during the operation ofthe. machine we providea chain-tightening device consisting of a ianged pulleyorguide-wheel 106, the kaxle of which, 107, is mounted in ra 95` slot 108 in a bracket 109, one. end of'whichis` hooked over the vrear frame -beam-.3withi which it is -tirnnly .connected-by means :of ja bolt 110, while the other end otsaid bracket is bent to form a hook 111, whichengagesthe f rock-shaft 34, upon which said .hook-rests andy is iirmly supported. .lt will beseen that by moving the pulley up against the lower lead of the driving-chain the latter may .be tightened to any extent that maybe required kto insure the smooth and perfect., operation thereof. fj. f -.f

lt willfbe observed that the v`.construction and arrangement of the partsof themachine aresuch that the inner coacting-leads of Athe conveyer chains are spaced.. apart -at their front ends and converge rearwardly. It fol-- lows that when the machine isin operation and the beets are elevated out of the ground by the operation of the inclined plane of the plow the tops of the beets will, as will., be readily understood, be seized upon by thesaid inner leads of the chains, and the beetsY will first be carried over the rearwardly-extendinglingers 11 at the rear end of the plow,.where.they'.,120

will be subjected to a shaking action wherebythe adhering dirt is separated therefrom. As the machine progresses the conveyerchains coperate to grasp the tops of. the .beets more tightly, and as thelatter progress rearwardlyy the rear part ot-l the supportingfframe.- namely,'the ox-bow frame 45. and itsrelated parts-will yield upwardly againstthe tension of the spring 48, thereby causing the machineto adjust itself. automatically to roots of various sizes.

ter pass within the range of iniiuence of the knife or cutter the tops will be severed from the beets without injuring the latter. At the point where severance of the tops takes place the grip of the conveyer-chains upon the said tops is tightest; but almost instantly after the severance of the tops, the beets having been dropped point downward upon the surface of the ground, the tops emerge from between the conveyer-chains and by the action of the curved rod 92 are thrown to one side, as will be readily understood.

Our improved beet lifter and topper as hereinbefore shown and described will be found to be extremely simple, durable, and effective in operation. While the form of embodiment of our invention which has been herein described is the preferred one, we do not wish to be regarded as restricting ourselves to the structural details herein set forth. Thus we have in Fig. 9 of the drawings shown a substitute for the rearwardly-extending fingers l, which consists in a polygonal roller 95, journaled in suitable bearings between the plow-standards and provided at one end with a sprocket-wheel 96, connected by a chain 97 with some rotary element of the machine. This device may at times be preferred for the purpose of guiding the beets into engagement with the conveyer s elements of the machine.

It is obvious that ordinary gearing may, if preferred, be substituted for the sprocket wheels and chains herein shown and described for transmitting motion between the parts of the machine.
