Application filed Iuly 2, 1902. Serial No. 114,061. (No model.)

To all whom, it may concern:

Be it known that I, MERRITT WESLEY PALMER, a citizen of the United States, and a resident of Hamilton, in the county of A1- legan and State of Michigan, have made certain new and useful Improvements in Beet- Toppers, of which the following is a specitication.

My invention is an improvement in beettoppers; and it consists in certain novel constructions Iand combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a top plan view. Fig. 2 is a vertical cross-section on about line 2 2 of Fig. l. Fig. 3 is a sectional side elevation on line 3 3 of Fig. 2. Fig. 4C is a vertical longitudinal section on about line 4 4 of Fig. 2 of a machine embodying myinvention. Fig. 5 is a detail perspective view of the main Vframe of the machine. Fig. 6 is a detail perspectiveV View of the verticallysliding frame which carries the topping and gage devices. Fig. 7 is a detail perspective view of one ofthe rocking frames for the cutter-shafts. Fig. Sis a detail perspective view of one of the guide-plates for the verticallysliding frame, and Fig. 9 is a detail perspective view of one of the lugged plates for application to the sliding carrier-frame and of some of the parts connected with said plate. Fig. l0 shows in perspective the lever for op erating the lever from which the sliding carrier-frame is suspended,also the keeper-plate for said lever. Fig. l1 is a detail perspective view of the rear logged plate. Fig. l2 is a detail cross-section on about line l2 l2 of Fig. 2. Fig. 13 is a detail perspective view of one of the cross-plates of the sliding carrierframe.

In carrying out my invention I employ a main frame A, (shown in detail in Fig. 5,) including the end bars A', the front cross-bar A2, the rear cross-bar A3, a top flange A4, extending outwardly from the end and cross bars A', A2, and A3 and having the forwardlyprojecting socket A5 for the tongue B,and 'the base-flanges A and A7, projecting, respectively, from the lower edges of the cross-bars A2 and A3. This main frame A is provided at its opposite ends with the guide-frames C, secured to the inner sides of the end bars A and having the vertical central slots C', open at their upper ends, and the lateral ears C2, through which they are bolted to the main frame, the bolts D for such purpose being also extended through the axle-frames E', which carry the stud-axles E, which latter project outwardly from their plates E' and are provided at e with squared portions, on which fit the upwardly and rearwardly inclined arms F, which carry the counter-shaft presently described. The main frame Ais also provided with an arc-shape bar G, arranged centrally between its ends A and extending from front to rear over the main frame and provided at its rear end with a keeper portion G', in which operates the main lever H, and supports near its rear end the keeper fi, in which is pivoted at I the lever I, which may be rocked on its pivot I `to cause its lateral Varm I2 to operate beneath the lever H when it is desired to operate the lever H by means of a chain I3, leading to the operator, who is walking behind the machine. It should be understood that the lever H carries the sliding frame shown in Fig. 6 and the parts carried thereby, such sliding frame being suspended by a hanger H or by other suitable means from the lever H, so the rocking of said lever H on its pivot H2 may raise and lower'the vertically-sliding carrier-frame. It will be noticed the lever H is provided with a handle H3, so it can be operated directly whenever' desired.

The sliding carrier-frame (shown in Fig. 6) operates within the main frame Aand will be more fully described hereinafter. The drivewheels J are mounted on the stud-axles E and are clutched atJ to sprocket-wheels J2, which are connected by sprocketmhains .i3 with sprocket-wheels J4 on the counter-shaft. K, which latter is mounted in the upper rear ends of the arms F and is provided at K with a sprocket-wheel, by which motion is imparted to the main shaft K2 of the carrier-frame by means of a sprocket-chain K3, as will be nnderstood from Figs. l and 4.

The sliding carrier-frame L is formed with the end plates M, having upright ribs M on their outer sides to slide in the slots C' on the guide-frames C, the front and rear plates N and N provided at their ends with the lugs IOS n and n', which are lapped along the inner sides of and secured to the end plates M. To the front and rear plates N and N' are secured the front and rear lugged plates O and P, which are riveted to the inner sides of the plates N and N', respectively, and are provided near their ends at their opposite edges with the inwardly-projecting lugs O' and P', to which are secured the plates Q, having boxes Q' for the shaft K2. The plate O is also provided at its middle with the upper and lower inwardly-projecting lugs O2 and O3, the upperlug O2 furnishing convenient. means for engagement by the hooked link H' and the lower lug O3 being arranged in position to support the depending bar R, which is provided at its upper end with the ear R', secured to the lug O3 and supportingr at its lower end the laterally-extending threaded rods R2, whose outer ends are threaded to receive the stopnuts R3 and extend beyond the said nuts R3 through openings S' in the rocking frames S. (Shown in detail in Fig. 7.) These rocking frames S are pivoted at their upper ends at S2 to the front and rear bars of the carrierframe L, are provided with the vertical bearings S3 for the shafts of the cutters, and are provided between their upper and lower ends with the bar S4, which is deflected at S5 to permit the passage of the cutter-shaft T, and this cross-bar S4 is provided with the opening S', through which the stop-rods R2 project and affords a connection at S6 for the end of the springS7, which connects the opposite rocking frames S and draws the same toward each other and permits them to yield apart in order to pass unyielding obstructions. The shafts T are provided at their upper ends with bevel-pinions T', which are meshed with the bevel-gears T2 on the shaft K2, so the turning of the shaft K2 by the connections previously described will cause the shafts T to rotate and the cutters T2 to operate upon the tops of the beets, as will be understood from Figs. 2, 3, and 4. A gage device comprising a ribbed roller U, mounted in a base-frame U', having front and rear hanger-bars U2 and U3, supporting it from the front and rear bars of the carrier-frame L, operates to limit the descent of the cutters T3. 'lhis gage-roller U operates in the central line of the machine slightly in advance of the points where the cutters T3 come yin contact, and a drag connection U4 connects the front end of the base-frame U' with the tongue B, extending upwardly and forwardly from the base-frame U' to its connection with the tongue, as showin in Fig. 3.

At the rear of my machine and preferably on the rear bar, at the point midway between `the ends thereof, I provide a bracket V, to

which may be connected the beet-pulling devices-such, for instance, as that shown in my Patent No. 699,561, issued May 8, 1902- in order to top the beets and harvest them by the one operation of the machine.

. As best shown in Fig. 1, swinging links W connect the counter-shaft with the main shaft, being provided at their ends with openings receiving the said shafts, as will be understood from Fig. l. p

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv l.
