' SAMUEL MOWER, OF SPRINGHILL, KANSAS.

LISTER AND GRADER.

SPECIFICATION forming part of Letters Patent No. 772,366, dated October 18, 1904.

Original application filed October 20, 1902, Serial No. 128,043. Divided and this application filed April '7, 1903. Serial No. 151,478- (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL MOWER, a citi- Zen of the United States, residing at Springhill, in the county of Johnson and State of Kansas, have invented new and useful 1mprovements in Listers and Graders, of which the following is a specification.

My invention relates to a propelled disk machine adapted for grading roads or land or for listing. l

The advantages of my herein described grading-machine over the usual plowsharegraders are that the soil may be cut to any desired depth and the grading can be accomplished much more rapidly than with the usual plowshare-graders.

My original application for United States patent upon this grading-machine was filed October 20, 1902, Serial .No. 128,043. Said application was divided, and this application is a part of the same.

I will now describe my invention with reference to the accompanying drawings, in which- Figure 1 is a rear elevation of a gradingmachine or lister embodying my invention, the caster-wheels and the scoop being omitted. Fig. 2 is a side elevation of the machine, showing also the rear portion of a tractionengine employed for drawing the machine and revolving its disks. Fig. 3 is a sectional elevation of the opposite side of the grader detached from the engine, the disk-shaft being cut on a line corresponding to line a b of.

Fig. 1. Fig.4 represents one of the casterwheel forks with its bearing-sleeve in section. Fig. 5 is an enlarged detail view of a portion of the elevator or conveyer. Fig. 6 is a further enlarged edge view of one of the elevator-plates. Fig. 7 is an enlarged detail view, in rear elevation, of the means for supporting the slidable shaft-hanger. Fig. 8 represents an attachment to be used alternatively to the elevator or conveyor. Fig. 9 is an enlarged face view of one of the disk-carrying wheels. Figs. 10 and 11 are a plan View and a side elevation of a modified arrangement of disks and disk-bearingwheels. Fig. 12 is an enlarged detail plan of the upper end portion of the elevator-frame, the braces 41 being in section.

22 is a transverseshaft which is supported by a rigid hanger 23 and a slidable hanger 24. Said hangers depend from opposite sides of a box or tender 21. Hanger 24 is mounted slidably in a bar 26, having a T-groove therein, (see Fig. 7,) said bar being secured to the tender. The shaft 22 passes through a block mounted to slide vertically in its hanger 24, and said block is supported adjustably by a right-and-left screw 27. Thus the angle of shaft 22 may be changed either vertically or laterally by adjusting the hanger 24 and the screw 27.

The disks 30 are secured on alternate sides of the disk wheels 28, and their concave faces all face in the direction in which the soil-is to be conveyed. Hence the hubs of half the disks are attached to their concave faces, and the hubs of the remaining disks are attached to their convex faces. The planes of these disks are preferably parallel to the planes of the wheels which carry them.

A sprocket-wheel29 is secured on shaft 22, near the stationary hanger 23, to receive a driving-chain, by which said shaft may be rotated by an engine and the disks 30 thereby revolved.

The caster-wheels are placed at or near the back of the tender, as shown, to provide space for an elevator, which may be constructed as follows: At the side of the tender from which a pair of hangers 3131. At the opposite side of the tender a pair of hangers 32 32 are secured to a shoe 33, which depends from the slotted bar 26 aforesaid. Connecting the lower ends of hangers 31 to the lower ends of hangers 32 are angle-beams 34 34, which form parts of the elevator-frame. These anglebeams extend laterally behind and below the disks, as shown, and their outer ends are connected by braces 36 to the hangers 32. On said braces are bearingsfor a shaft carrying sprocket-wheels 3 7 37 over which passes the elevator, described hereinafter. Secured to the opposite ends. of the angle-beams 34 are a pair of obliquely-rising angle-beams 4O the stationary hanger 23 depends are secured 40, which form extensions of the horizontal beams 34. The upper ends of the inclined beams 40 are braced by braces 41 41, secured to the side of the tender. Bearings for a shaft carrying sprocket-wheels 39 are secured to beams 40 and braces 41. Secured to hangers 31 are bearings for a shaft carrying driving-sprockets 38 38, which drive the elevator by engaging the cross-rods thereof. On said shaft is a bevel-pinion 42, which is driven by a bevel-pinion 43 on a short shaft on which is fixed a sprocket-wheel44. On the disk-shaft 22, in alinement with sprocket 44,is a sprocketwheel 46, and said sprockets are connected by a chain 47 Depression-rollers 48 48 are employed to hold down the upper run of the elevator, so that the upper run will be substan-' tially parallel to the lower run. The elevator itself passes over the elevated sprockets 39 and is composed of a pair of chains 49 49, connected by cross-rods 50, and sheet-iron plates 61, hinged, respectively, on said rods. (See Figs. 9 and 10.) The plates 51 are cut away at their sides, as shown, so that they will not ride over the sprockets at the ends of the elevator. The sprockets work just inside the links 49 that is, between the links and the plates 51. Secured to one face of each plate 51 is a flight 52, the action of said flights being to engage the soil which is thrown upon the plates by the disks 30. Said flights are of course on the upper sides of said plates in the lower run. In the upper run the plates hang from the rods 50, as shown in Fig. 1.

Secured in any suitable manner to the forward horizontal beam 34 of the elevator-frame is a scoop 53. (Shown in Fig. 2.) The rear edge of this scoop is raised above its front edge, and the scoop is arranged to catch the soil,which would otherwise drop to the ground in front of the elevator when the disks are in action. The soil so caught will work back upon the elevator-plates by the kicking action of the disks.

The purpose of the upwardly-inclined extension of the elevator is to raise the soil high enough to dump it into wagons, if desired. The upper ends of the inclined beams 40 are cut away, as shown in Fig. 12, to permit the elevator-plates to drop before the chains commence to round the sprockets. In the entire lower run of the elevator the plates 51 are supported by the lower flanges of the

anglebeams

34 and 40. The inclined extension of the elevator may be detached, if not required, and the elevator shortened to pass around sprockets 38. Moreover, the entire elevator and scoop may be detached from the tender. In that case I would employ behind the disks an arcuate curved plate 54, Fig. 8, supported by rods, as 59,. depending from the crossbeam secured to the bottom of the tender and braced by rods, as 57, the upper ends of be employed for listing also.

which are attached to the disk-shaft 22. The purpose of the plate 54 is to prevent the soil from being thrown back by the revolution of the disks.

Referring to Figs. 10 and 11, these views represent a modification of my system of disks as attached .to wheels, the modification consisting of running a plurality of eccentric shafts 58 through the wheels parallel to the central shaft 59. The disks are mounted upon these eccentric shafts. This construction might be somewhat stronger than that shown in Fig. 1 with respect to the connections between the disks and their carrying-wheels.

The herein-described grading-machine may Hence in the appended claims I would term it a lister or grader.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
