ROGER SANDIFORD, OF JOLIET, ILLINOIS.

Letters Patent No.' 90,961, dated .Tune S, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

Beit known that I, ROGER SANDIFQRD, of Joliet, in Will county, and State of Illinois, have invented an Improved Land-Roller, Land-Marker, and Harrow combined; andI do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, in which- Figure l is a plan, or top view of the roller and marker;

Figure 2, a front elevation of the same;

Figure 3, a plan, or top view of the frame, with the barrow attached;

Figure 4, a front elevation of the same;

Figure 5, a sectional view of the rocking couplingbox, on the shaft; f

Figure 6, a diagram, showing that each roller may be on a different plane and parallel with each other at the same time; and

Figure 7, a View of thebottom 'of the barrow-plate,

or disk, showing the flanges thereon.

The object of my invention consists in the arrangement and'combination offa'land-roller, land-marker, and barrow, and the devices by means of which the same is effected. A

The rollers a are so arranged that the same may be parallel with each other, and on a different plane at the same time, as shown in fig. 7.

This is accomplished by means of a'rocking couprling-box, c, on the round-shaft b, in combination with the frame-joint boxes e, which are attached to the main wooden frame' d by means of a bolt, forming a hinge, as shown.

Fig. 5 more explicitly shows this coupling-box c. The part l 1 rocks on the shaft 3, and has hinged thereto the hubs 2 2, which receive the roller-shafts 4 1 11 as shown, (the numerals relating only to iig. 5.)

The annular adjustable V-shaped projections f, on the rollers, are for the purpose of converting the mai chineinto a marker. These vprojections are adjustable by means of bolts, or. screws, as shown, so asto make the marks at any desired distance apart.

'For the purpose of converting the machine into a barrow, l insert, in place of the rollers a, into the fra-me d, the circular hai-rows h, which consist of a metal, or wooden disk, with radial projections on the under side, as shown in fig. 7. These projections are for the purpose of giving support to the teeth, and to pulvem'ze the lumps.

These harrows-revolve on a pivot Aat the centre, in the centre arm, or bar i, and are pulled by the chain m attached to the main frame d, as shown.

The depth of the harrowin the ground is regulated by the travelling wheels n, n, and o.V

The wheels n vn are adjustable up or down, on the end of the main frame, as shown, and the wheel o is operated by means of the crooked shaft ll'. These I wheels also take the weight either wholly or partially on" the harrows, as desired, and may be so adjusted as to cause the harrows to revolve in either direction.

The machine is furnished with a seat, s, for the driver, and rests on an adjustable frame, z, hinged to the main frame,sothat he may sway himself from one side to the other, to bring the seat to a level, or place the weight at any given point.

t is a box used for tols, or, if necessary', weights.

u is a metal seat for the tongue, and is either loose or permanently fixed on the round shaft '6, which is stationary, so that the oscillations of the machine will not affect the tongue.y j I would further say, in relation to the flanges, or projections on the under sideof the harrow-disks, or plates, they are also for the purpose of assisting thev teeth, in causing the harrows to rotate, as it is found that the teeth alone are insufficient' to cause perfect rotation.

` The brace-box x is attached and iirmly fixed to the e inner end of the round' shaft b, and serves to hold th braces to the main frame d, as shown.

The centre bar, or arm i, which holds the barrow at its' centre, takes the place of the roller-shafts when the machine is converted into a harrow, the ends of which iit into the boxes on the main frame d, and rocking coupling-box c, in precisely the same manner as said roller-shafts. This centre arm, or bar, is constructed of metal, depressed or bent down in the centre, as shown, to meet the harrow and receive the spindle upon which they revolve.

Figure 8 shows, more particularly, the construction and arrangement of the crooked bar fr, which is fixed to the main frame d by means of the boxes y y, in which it operates. v

This crooked bar has attached to the lower end the Wheel o, by means of which` the centre of the machine may be elevated or depressed at the will of the driver having. hold of the upper end.

Figure 9 shows the means by which the outer wheels n may be adjusted up or down.

' The axle of the wheel is attached to the standard` x', and may be moved up or down in the slot, as shown, by simply loosening the nut on the end of lthe axle bolt. This standard x is fastened to the main frame ll by bolts, as shown in fig. 9.

The rollers are placed in the frame d by means of a shaft, 4, in fig. 5. This shaft, at the outer end, enters in a box in the main frame d, and is attached, as shown in fig. 5, tothe rocking coupling-box c, andthe rollers turn with said shaft, to which they are keyed.

The crooked -shaft e" may also be attached to the centre of the machine by a box sleeved on the main round shaft b, as shown in the drawings, figs. 4 and 8, as well as by boxes y, attached to the main frame d.

The standardsof the outer wheels may be attached or secured to the main frame d by either vertical or horizontal bolts, which I do not claim as material.

4. The crooked centre arm i, in combination with the main frame and chains, as set forth. K

5. The lever and crooked bar fr, with roller 0, for the purpose described.

6. The outer wheels n n, in combination with the centre Wheel o and barrow-frame d, when arranged, operating, and constructed as set forth.

' ROGER SANDIFORD.
