SPADING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 332.703. dated December 22, 1885. Application tiled August 3,1885. Serial No. 173.457. (No model.)

.To all whom, it may concern:

Be it known that I, WILLIAM E. DEPP, a citizen of the United States, residing at Brookville, in the county of Jefferson and State of Pennsylvania, have invented a new and useful Improvement in Spading -Machines of which the following is aspecilication, reference being had to the accompan ying drawings.

Myinvention has relation to improvements 1o in spading-machines; and the novelty consists in the construction, combination, arrangement, and adaptation of the various parts for service,substantially as hereinafter fully set forth, and particularly point-ed out in the claims.

The object of my invention is to provide a spading-machine which shall excavate the earth at predetermined distances for planting potatoes, or to prepare the ground for seedsowing without the use of a barrow; to regu- 2o late the depth ofthe excavation or cut; to automatically clean the digging or spading implements from the earth or dirt, and thus prevent them from clogging up and becoming inoperative, and to combine simplicity, strength,

and durability of construction with efliciency of operation and cheapness of manufacture.

In the drawings hereto annexed, and which form a part ofthis specification, Figure l is a perspective view of a spading-machine con- Structed in accordance with my invention.

Fig. 2is a longitudinal section on the line xm of Fig 1. Fig. 3 is a detail View of the means for adjusting the supporting frame bearing-wheels. Fig. 4 is a detailed detached view of one ofthe eccentric or cam wheels for operating the digging implement or spade. Fig. 5 is a detail view of one of the spading or digging implements. Figs. 6 and 7 are detail views.

Like letters of reference indicate like or corresponding parts in all the figures of the drawings, referring to which A designates the supporting-frame, comprising parallel side and cross bars, a ct', re-

spectively, suitably connected at their ends in any preferable manner and adapted to form "'aframe, which is preferably rectangular in l form.

A designates the draft-pole, suitably con- 'nected to the frame A at its front end.

BB designate the supporting-frame A bearing-wheels, mounted upon short axles b b, which arejournaled at one side ot' the frame in a bracket or standard, D, depending from the frame A near the middle ot' the side bars 55I thereof, said axles b b being connected to or forming a part ofthe bent axle C. which comprises two parallel side bars, OO, arranged under and in alignment with the side bars of the supporting-frame A, and a` horizontal 6o cross-bar, O", connecting the front ends of the bars O together, and serving to support the bent axle O by being journaled in boxes c c, suitably secured to the front cross-bar of the lower face of the frame A, the rear ends ot' 65 the parallel arms or bars OO being connected to the short axles b b. The axle C may be made from a single rod, bent to form the parallel bars C C, the cross-bar O2, andthe stubaxles bb, and'pivored at its front crossbar, C2, 7o in the frame A, and at its rear end in the bracket D, for simultaneously raising and lowering the bearingwvheels B B. The bracket or bar D is provided with a series of teeth at one edge of its upper end, with which meshes a toothed segment, E, pivoted at e to the side bar of the supporting-frame, and having an operating -handle, E', extending upwardly therefrom above the frame A and Within easy reach of the driver, seated in the seat F, sup- 8o ported upon a standard, F, bent as shown, and connected at its lower front end to one of the side bars of the main frame, said seat being arranged at one side of the main frame out of alignment therewith and over the bearingwheel, in juxtaposition to the opelatinghandle E. The handle E is held in any desired position or adjustment by means of a bolt, G, sliding between perforated lugs g g of the handle,andkept normallyin engagement with 9o one of a series of notches, h, formed in a bow or segment, H, by means of a spring, G', arranged between the lugs g g, and coiled over the bolt and bearing at its lower end against a pin passing therethrough. The bolt is retracted from engagement with the notches h of the segment or rack by means of a fingen lever, G2, preferably right-angled in form and pivoted upon the upperend of the handle-bar E, and connected to the bolt G at the upper roc end thereof by means of a link, Gaf The lower arms of the segment H are fitted in mortises formed in one of the side bars of the frame,

and are held therein by screws or bolts.

I designates the axle for supporting the bearing-wheels J J, arranged on yeach side of the impleinent-carrying wheel K, said. axle beingjournaled at its ends in the side bars of the main frame or in suitable boxes or bearings provided therefor, and rigidly held in position therein to enable the bearing and spading wheel to rotate freely thereon. The axle is screw-threaded, as at t', leaving. the ends free and plane, on which the hubs j of the bearing-Wheels fit, and are held in place by means of nuts j', tting against the faceof said wheels and working on the screw-threaded portion, the bearing and implement wheels being connected together at their outer edges by screw-threadedbolts I,arranged at the periphery of the said wheels and passing through the same, said bolts or rods l being held in position by means of nuts i i?, arranged in pairs and adapted to bear on opposite faces of the several wheels, t-he nuts i2 having a washer, i3, arranged between them and the outer face of the implement-carrying wheel K. The wheels J are preferably made skeleton in form for lightness and strength, are arranged at each end of the axle, and when the machine is in operation they bear upon the surface of the ground and prevent lateral strain upon the axle and iniplement-carrying wheel K, only one of which is shown in the accompanying drawings for thevsake of clearness; but it will be understood that two or more of such implement-wheels K may be employed, as circumstances may require. The Wheel K is of the same diameter as the bearing-wheels, and held in position between the bearing-wheels J J by means of the crossbolts I and nuts i2. At the periphery of the wheel Kit is provided with two lateral iianges,

k Ic, arranged concentric with and a short distance from each other, being separated by an intervening concentric space or groove, k, the iianges being arranged on oiie of the side faces of the wheel and one below the other. This wheel is without a hub, and lying within the same is a cam or eccentric wheel, L, having a screw-threaded hub, l, fitted on the axle I and lield thereon. The eccentric wheel L is made skeleton inform and flat or disk-shaped, except at diametricallyopposite points at its periphery, where it is cut away, as at Z Z', and provided with an outwardly-bent and forwardly-projecting cani-tongue, Z2, the inner edge of which, where itjoins the body of the cam-wheel, being beveled, as at Z3, to enable the cross-heads of the spading or digging implements to slide or move freely thereon with a minimum of friction.

M designates the spading or digging implements arranged around the circumference of the carrying-wheel K and exteriorly thereto at one side thereof, said implements comprising a blade, m, rigidly secured upon a shank,

m', having a washer, m2, arranged between the d lower end ofthe blade and the exterior face or periphery'of the wheel K, to take up the friction and wear thereon. The shanks m of the spading-implements pass through the flanges k le of the wheel K, and are free to rotate therein, said shanks being provided at their lower ends, beneath the inner concentric groove of the carrying-wheeLwith two cross-heads, N O,

the latter of which is arranged below and at right angles to the former. rlhe cross-head N normally lies transversely across the' lower inner face ofthe lower flange or rim of the wheel, While the other cross-head, O, being arranged at right angles tothe cross-head N,

normally lies within and parallel with the said flange or rib k, the two cross-heads being connected by an intervening stud, O', and formed integral or cast in one piece with each other. The upper cross-head, N, fits between the under or inner face ofthe lower flange, lr, and the periphery of the cam-wheel L, and when one of the arms of said cross-head comes in Contact with the forwardly and upwardly projecting cam-ledge Z2 of said wheel itl turns or revolves the spading-implement shank and lower cross-head, so that the implement-blade will be parallel with the face of the wheel K and the lower cross-head transversely -across the same, bringing one of the arms of said lower cross-head, O, in contact with the bev- A.

eled ledge or portion Z:s of said cam'- wheel,

and upon further-rotation of the carrying- IDO wheel the arm in engagement Withfthe bev-.-

eled ledge Z3 will complete the rotation of the implement-blade, so as to cause the same to lie transversely across the face or peripheryl of the carrying-wheel in their normal position, and rotate or turn the Lipper cross-head,

so as to cause its arms to lie transversely' across the inner surface of the flange k, and

bring the lower arms of the lower cross-head to lie against and parallel with one of the faces of said cam-wheel until the device or imple-- ment comes to the next cam ledge or projection, when the operation above described-is repeated.

There may be any number of spading im rio plements arranged around the wheel, and the cam-wheel may have two or more cam tongues or projections.

The blades of the implements may be square and arranged'in an inclined position,as shown,

or they may be rounded at their cutting-edges,

or fork shaped. The cross heads may also have beveled faces where they come in contact with the cam-tongue. f

It will be observed that the implement-carrying Wheel is supported by and rotated with the bearingwheels J and independently of the axle, and when the cross-heads of the implei'nent come in contact with the cam-wheel tongues they are given a complete turn or rotation, which eifectively clears them from dirt or earth.

rIhe bearing-wheels of the main frame can be adjusted up or down, to allow the spades Iso of the carrying-wheel to go deeper into the earth, by merely withdrawing the bolt G and adjusting the handle-lever forward, the lower serrated segment working in the toothed bracket D, to adjust the wheels and axle to the required degree. The bracket is held in place by means of a guide, D', which bears against the face of said bar D, and is secured to the frame A.

The device can be readily converted into a seed-dropper by mounting a hopper on the frame and connecting the slides of said hopper with means-as, for instance, the crossheads-for being automatically operated by the cam-wheel.

The operation of my invention will be readily understood from the foregoing description, taken in connection with the drawings.

Modifications in details of construction and form and proportion of parts can be made without departing from the principle or sacriicing the advantages of my invention.
