Claims. 1

This invention relates to an improved machine for cleaning beaches andlan'd, and one of its.

objects is to provide a machine which will raise surface portions of the sand of a beach, or of land, and cause such raised portions to pass through a separating screen, so that undesired debris or waste, like paper, broken glass, coins, paper money, jewelry, stones, and other objects, may be separated fromthe useful portions of the beach or land covering.

Another object of the invention is to provide a machine of this character which maybe hauled by a motor or animal drawn vehicle; and which will maintain, while being moved over the-beach or land, a rotary drum in'motion, and which will operate to scoopup surface portions of the beach or land, and project them over an inclinedscreen, so that the finer particles will pass through the screen and the larger andundesi-red objects will drop through openings in the screen and be collected by a pan-located under the screen.

Another object of theinven-tion is theprovi'si'on' of a machine for this general-- purpose, with meansfor raising the excavating drum so that it will not engage the ground.

A still further object of the'invention" is the provision of a land and beach cleaning machine; with means for engagingand disengaging the excavating drum from driving gears or sprocketsmounted onthe rear axle, which is supported so that it will turn with the rear wheels.

With the aboveand other obj'ectsin view the invention consists in certain new andi'useful constructions, combinations and arrangements" of. parts, clearly described in the followingspecification, and fully illustrated in the accompanying drawings, in which:

Fig.. 1 is a top plan view of. the iinproved machine.

clutches and driv- Referring to the accompanying drawings which illustrate the practical construction of myinvention 5 designates a main frame, on the rear end of which the rear axle B is supported by the bearings l and 8. This rear axle is equipped with ground wheels 9 and I0, each of which is formed or provided with ground engaging cleats or teeth I I.

The forward end of the frame is supported by the front ground wheels I2 and I3; which are mounted by the pivot members I 2a and i312 on the front axle I4, which is supported bythe frame bracket lugs or members l5 and I6;

Forwardly of the rear axle an excavating drum I1 is-arra'nged; which is provided with stub'shafts' l8 and l 9 on the ends thereof. These stub shafts project into the bearings 20, which slide between the arcuate guides 21' and 22; of the bearing plate 23. The bearings 20- are mounted on the for-- ward ends of the levers 24, the rear ends of which are mounted directly on the rear axle, through the bearing 25, so as to permit the axle to turn withoutcausing the levers to'swing'.

The: excavating drum I1 is provided with abuckets or members 26, which are designedto scoop beachrsand or: surface: land covering and project it forwardly over the screen 21, which is inclined downwardly and forwardly-from a point near the forward peripherai surface-of the excavating drum.

The rear axle is equipped withs'procket wheels 28" and 29, which: are not keyed thereto for rotation. with the axle, and sprocket chains 30 and-:31 transfer'motion. from the drive sprockets 28' and 29"to the driven sprockets 32 and tit-on theen'd shafts t8 and: I9 of the excavating drum IT. The driven: sprockets are considerably smaller than th'ed rive sprockets, so that the excavating drum will rotate at a faster speed than the rear ground. wheels turn.

The drive sprocketsare: provided with: clutchelements in the form of spaced apart sockets 28a and 29a, which are adapted to receive the teeth 34a of the clutch element 34, and the teeth 35a of the clutch element 35, both mounted on the rear axle. These clutch elements are in the form of collars and are positively keyed to the rear axle so as to turn always with the rear axle. The clutch element 34 is provided with a ring 3412 which is formed with a shifter groove 34c,

which is engaged by the stud pins 36 of the spanner shifter 31, which is pivoted to the cross bar 38. The clutch element or ring 35 is provided with a ring 35b, which is formed with a spanner groove 35c, and this groove is engaged by the stud pins 39 of the spanner 40, which is also pivoted to the cross bar 38.

A vertical lever 41 is pivoted to the cross bar 38, and is pivotally connected by the link 42 to the spanner 31, and is further pivotally'connected by the link 43 with the spanner 49. By swinging this lever to the left, when in the position shown in Fig. 3, both clutches will be engaged, and motion will be transmitted from the rear wheels, through its axle, through the drive sprockets and chains to the driven sprockets of the excavating drum.

The excavating drum is raised by means of a yoke 44, which is pivoted at its ends to the levers 24, and this yoke'is provided with an upstanding arm 45, which is pivotally connected to the lower end of the jack screw 46.

The jack screw 46 is mounted to turn on the standard or frame 47, which is mounted on the top plate 511, and this screw is threaded to the head 48 of this frame 41. By turning the wheel 49 of the jack screw the yoke will be raised, as the lower end of the jack screw is swivelled to the arm 45 of the yoke, and the ends of this yoke are pivotally connected to the levers 24, which carry the drum bearings 29.

The tension of the sprocket chains may be regulated by means of the screws and 52, which are threaded through the bar 50, which is fixed to the frame 5. The ends of the screws 5| and 52 engage the bar 53 of the sliding bearing plate 23, and by tightening or loosening the screws the bearing plate 23 may be shifted on the frame 5, which is in the form of a channel bar.

The screen 21 is provided with grooves 210 and 21d, which end with the discharge openings 21c and 21f, and auxiliary side screens 21a and a vertical front baffle screen 21b are provided for confining the movement of projected sand or earth over the separating screen 21. A pan P is arranged under the openings Zle and 21 and these openings may be arranged on the side and buckets or receptacles provided for receiving the discharge thereof.

The excavating drum may be provided with frame, ground wheels on the ends of the axle, a rear axle mounted to turn on the frame, ground wheels mounted on the ends of the axle to turn therewith, sprocket gears mounted to turn on the rear axle, clutches for coupling the sprocket gears to the rear axle, means for simultaneously operating both clutches, an excavating drum mounted to turn on the main frame, said excavating drum having curved land digging blades, sprocket gears on said drum, chains engaging the gears of the rear axle and the drum gears for transmitting motion from the rear axle to the drum gears, a separating screen mounted on the curved prongs or tines 56, as shown in Fig. 8,

on the drum 54, which is provided with the usual gear sprocket 55, shown conventionally.

The machine may be coupled to a vehicle by means of the draft tongue 51, and may be provided with a seat 58 at the rear end thereof. An engine or power plant may be also added for driving the rear axle by a sprocket transmission.

Various changes in the details of construction and arrangement of parts may be resorted to, without departing from the scope of the invention, as defined in the claims hereof.

Having described my invention I claim as new:

1. A land cleaning machine, consisting of a main frame, a forward axle supported on the main frame and inclined from a point near the drum to the forward end of the machine, said screen having an opening located at the lowest end thereof, and a receptacle located below said opening.
