Claims

Claim 1st An elevating wheel of a ditching machine having a segmental rim composed of plates separated from each other but all rigidly bound together by two metal rings about the same diameter as the periphery of the wheel and forming a flange on either side of the segmental rim to constitute the rigid connection specified. 2nd. In an elevating wheel of a ditching machine having a segmental rim composed of plates separated from each other but bound rigidly together by two metal rings secured to and on either side of the said plates, the combination of body pieces hinged to and between the metal rings so as to form with the plates a series of discharging earth buckets, substantially as and for the purpose specified. 3rd. In a ditching machine in which the body piece of each earth elevating bucket is hinged between rings forming sides to the tyre or rim of the wheel, a series of plates forming the bottom of the buckets and also the segmental ring of the wheel, each plate being flanged behind the pivot point of the buckets while that portion of it which forms the bottom of the bucket is inflanged and is of such a width that the body piece can work freely between it and the rings to which the plates are rivetted. 4th. In a ditching machine in which the earth is elevated by a series of buckets arranged round the periphery of a wheel, each bucket being composed of a stationary bottom and a hinged body piece as described, the combination of a series of rollers located at the discharging spout of the elevating wheel so that the body of the buckets will come in contact with them so as to be pushed back clear of the outer rim, substantially as and for the purpose specified. 5th. In a ditching machine in which the body piece of each elevating bucket is hinged as described and is provided with a friction roller as specified, the combination of a spring cam bar so shaped and arranged that the body piece of each bucket as it approaches the ground is forced out beyond the periphery of the wheel in order to constitute a grip to prevent the wheel slipping, substantially as and for the purpose specified. 6th. In ditching machine in which the body pieces of the elevating buckets a are thrown in and out as required by a cam bar, a joint formed in the said cam bar near the point where the buckets commence to raise the material, in combination with a spring arranged act on the said cam bar near the said joint so that, while forcing the body piece out to form elevating buckets, they will give should they come in contact with an obstruction. 7th. In a ditching machine in which the earth is elevated by a series of buckets formed on the periphery of a wheel, a spade or plow carried in bearings so arranged that when the spade is raised or lowered it will follow the circle of the said wheel. 8th. In a ditching machine in which the, earth is elevated by a series of buckets formed on the periphery of a wheel, a curved plate held in position by a spring so as to form a back to the buckets while elevating the earth, in combination with sides detachably fixed to the plates so that they can be readily removed when the machine is to be worked in sticky ground. 9th. In a ditching machine in which the weight of the machine is carried by the earth elevating wheel journalled in a frame adjustably connected to a steadying frame supported by two wheels, one on each side of the machine, the combination of a stay rod fastened to the axle of each wheel and extending obliquely to the tongue of the machine in such a manner that their connecting point or points move longitudinally on the said tongue to permit the free vertical movement of either, the steadying frame or the tongue, substantially as and for the purpose specified. 10th. In a ditching machine, the combination of land sides F1 made slightly wider than the elevating wheel and located, substantially as and for the purpose specified. 11th. In a ditching machine, in which the elevating wheel is operated by the forward movement of the machine, the combination of the castor wheel A arranged to support the frame of the machine and adjusted by steering gear operated from the drivers' seat.
