E. CHARLES BEAN AND FRAN CIS N.'WELDEN. OF ROCKFORD, ILLINOIS.

. Letters Patent. No. 96,382, dated November 2, 1869.

IMPROVEMENT IN QUL'I'IYATORS.

The Schedule referred n3 those Letters Patent and making part of the lame.

To all whom itma'y concern Be it known that we, E. CHARLES BEAN and FRANCIS N. Wnnnss, both of Rockford, in the county of Winnebago, and State of Illinois, have invented a new and useful Improvement in Cultivators; and we do hereby declare that the following is a-full and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to that class of wheel cultivators in which a main frame, carrying the seat and lifting-devices, is employed, in connection with an auxiliary frame carrying the shovels; and

It consists First, in the employment of bent metal bars, in

connection with the axle, pole, and braces, to form the main frame of the machine.

Second, in the specific construction of the adjustable foot-west, and the standard upon which it moves.-

Third, in the combination of the bearing-blockupon the shovel-standard, with the bearing-plate upon the. shovel-beam.

Fonrth,-in the combination of. the bearingblock,

bearing-plate, and hook-bolt, with the shovel-beam and standard.

Fifth, in the construction of the hand which encircles the lower part of the standard, and unites the latter to the lower end of the brace-rod.

Sixth, in the efnploymentof wings or arms for the purpose of catching and guiding the corn.

Figure 1 is a plan view of my invention.

Figure 2, a side elevation, with wheel removed.

Figures 3, 4, 5, 6, 7, 8, views of parts detached.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and operation,

A represents a bent axle, of wrought-iron or other suitable material, which is supported by the wheels 0. (1-, as shown.

- B B represent metallic bars, bent in semi-oval shape, with parallel projecting ends, which are united in'front by means of the pole C, to which the front endsof the b ns are bolted, and in rear, by means of boltspassing through the parallel ends of the .bars,-as shown. These rear ends'are not closely united, but by means-of a washer or itsequivalent, upon the bolts, are slightly separated, and a slot is thus formed, in which movesthe perpendicular bolt attached to the scat-standard. This standard rests upon these ends, and is adjusted to the front-or rear at will, by simply loosening the nut or the boltwhich holds the standard to the bars. If desired, instead of securing the standards to the bars by means of a. bolt, it may be fastened by placing a clip over its base and about the bars. The bars B are also attached to the axle at their point of union, by means of clips.

These parts, in connection with the pole O and braces D, form the main frame,- upon which are placed the lifting-devices and seat, and from which depends the auxiliary fi'ame;

The braces D extend from the point of union of the bars B with the pole, to some suitable point upon the elbows of the axle, and from thence to the lower end of the rack-bar G.

F represents the pulley-standard, which is constrncted of a bent metal bar, having diverging sides ending in curved bases, as shown. This standard is secured to the axle by means of clips, in order that the latter mayrlot be weakened by boring it.

G represents a curved rack-bar, the rear and lower end of which is attached to the rear end of the brace, and the upper and forward end to the pulley-standard, the bar being secured to the latter by the some bolt that holdsthe pulley in place. 7

H represents a lever, which isv provided with the usual spring-lock devices, whichengage with the rackbar, as shown. Its lower end is attached to one of the sides of-thc pulley-standards, as shown.

71. represents the lilting-chain, one end of which is attachedto the lever, and the other to the ends of the bar J, as shown.

I I represent the shovel-beams.

These are united in rear by means of the adjustable bow-shaped bar J, and in front by means of the iron j bolted thereto, which is hooked into the poleiron j, as shown in fig. 2.

K represents the shovel-standards, which are much of the ordinary construction.

They are held in place by means of the hook-bolt M.

m; represents the bearing-block, which is constructed with the flange m, as shown. I

. nrepresents the bearing-plate, which is provided with the recess n, which corresponds in size with the flange m of the block m. g l 0 represents a band, which encircles the lower part of the standards.

It is provided with the staple-shapcd projection 0, into which is caught the book 0, which latter isv provided with a socket for the reception of the lower end of the brace-rod, the two being united by. means of a wooden pin, in the usual manner.

P represents wings or arms, of any which are preferably attached to the suitable form, under sides of the shovel-beams, and extending outward at nearly right angles thereto, catch the corn, which would, be otherwise guided by the shovel-beams out of the line of the. shovels, and draw it into its proper place in the centre of the machine, between the shovels.

R represents an adjustable foot-rest, which consists sired point.

of a. foot-shaped casting, having an eye, 1', provided with the perpendicular slot '5, and perpendicular recess i which latter extends .only partly through the casting, and a. standard, S, having, at suitable and regular intervals, the projections s, which correspond, in size, with the slot 1'.

The general operation of our machine is similar to others of this class, and need not here be part cularly described.

The advantages of the special construction herein described, and the operation of the specific devices,

may be briefly set forth as follows: i

The construction and arrangement of the .main frame are sucbthat a light structure is produced,which, nevertheless, is suificiently strong to bear. the strain incidental to its work. The centre part of it is left entirely open, a.nd the view, therefore, of the crop .is entirely unobstructed. The parts are nearly all u'nited by clips, and consequently the entire strength of the material is preserved. The pulley-standard is. attached firmly to the axle by means of the clips, without boring the latter.

The arrangement of the rack-bar, the pulley-standard, the axle, and the brace, is such that the parts mutuallystrengthen each other, and form a. rigid fi'ame-work for the operation of the lever.

The foot-rest is easily adjusted upon the standard by moving the slot into line with the projection upon the standard, and dropping it or raising it to the de- It is held'in place,- and prevented from turning, by causing the projection upon which it rests to enter the recess 1?,in which position it is securely held until again disturbed.

The construction of the bearing-block, with a flange fitting into the recess-plate, enables the hook-bolt, to be withdrawn without causing the bearing-block to drop out of place. In the ordinary form in use, whenever the bolt is remover], the block must be removed also, andit is consequently extremely liable to be mislaid andlost. By the construction herein described, as the bearing-place is'secured to the. beams, the block is always in place unless removed by design.

By the peculiar construction of the band which encircles the lower part of the standard, the end of" the brace-rod is given a certain necessary play, as-the standard is moved to adjust the shovels in relation to the crops.

The construction of the seat is such that it mryhe adjusted readily, either forward or backward, to club e riders 0i dilfcrent weights to balance thepole and re be straight or curved, and arranged in any suitable manner, to catch the corn and guide it into the centre.

The joint, by means of which the main frame is connected to the auxiliary frame, is extremely simple, and still very strong.

The beams themselves are closely connected together, instead of being spread apart, as is usual, and the iron serves to bind them still more strongly together.

The entire machine is of little weight, and is graceful in form and e'fiective in action.

Having thus fully described our invention,

. What we claim as new, and-desire to secure by Letters Patent, is-

1. The combination of the bent metal bars, the

axle, the pole, and the braces, to form the main frame of thenrachine, substantially as described. it

2. The combination of adjustable flint-rest R with eye. 1'; having the slot 7" and recess r, with the standard S, having the projection s, as and for the purpose described.

3. The combination of the flanged bearing-block with the recessed bearing-plate, as described, for the purpose set forth.

4,. The combination of the flangedbearing-block, recessed bearing-plate, and hook-bolt, with the shovellfieam and standard, as described, for the purpose set orth;

5. The band 0, provided with the staple-shaped projection o o, as and for the purpose described.

6.- The cmployment. of wings or arms, or their equivalents, substantially as described. for the purpose set forth.

This specification signed and witnessed, this 21st (lay of August, 1869.
