VILLIAM A.v DOUGLAS, OF BR'ONSON, MICHIGAN.

WH EEL-CULTIVATOR APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 606,835, dated July 5, 1898.

Application filed March 30, 18 9 7 sentiero. 630,014.. (No man.)

To @ZZ whom; it may concern:

a citizen of the United. States, residing at Bronson, in the county of Branch'a'nd State of Michigan, have invented a new and useful Appliance for Combining a Garden-Wheelbarrow and GardenfCultivator', of which the following is a speciication.

My invention relates to improvements in a convertible wheelbarrow and cultivator, in which I have combined and arranged the several elements in afmfanner to enable the implement to be used either as a Wheelbarrow or as a cultivator with a few changes in the construction of the implement.

A further object of the invention is to provide for the secure holding of the walls and bottom of the structure when adjusted for service as a wheelbarrow.

A further objectfof the invention is to enable the structure when used as a cultivator to be adjusted to regulate the height of the handles or the depth of penetration of the:

cultivator tooth or teeth.

To the accomplishment of these ends my invention consists in the novel combination of devices and in the construction and arrangement of parts, which will be herein ai' te fully described and claimed. v To enable others to understand my invention, I have illustrated the preferred embodiment thereof in the accompanying drawings,

forminga part of this specification, and in Which-f Figure 1 is a perspective View of thestructure adjustedfor service as a wheelbar'row."

Fig. 2 is apersp'ec'tive'view showing themachine adjusted -as a' cultivator. Fig. 3 is a Fig. 1.1] Fig. tis 'a detail perspective view of the cultivator-standard, its rock-shaft, and

the clamp for'attaching the standard ory stock to said' rock-shaft. Fig. 5 is a detail View, partly in section, to show the clamp for attaching'the cultiv'atorl standard or stock to the rock-shaft or cross-bar.

Like numerals of reference denote corresponding parts in all the figures of the drawings.

I construct-my improved vma'zhinewith a frame which is arranged for service in connec- 'board 1l. j VWith cleats 9, which are extended-below the p tion with the elements that constitute, in con- Be it known that I, WILLIAM A. DOUGLAS,

nection'with said frame, the wheelbarrow or the cultivator. This frame comprises the'side rails 2 2, the cross-bars 3 3, the legs 4 4, and the aide 5, which sustains the carrying-wheel 6. The side rails 2 are arranged in slightly-di- ,.vergent positions with relation to each other,

andthe rear ends thereof :are formed into the handles, by which the operator is enabled to easily and firmly grasp the implement to direct and control the same. The side rails, the cross-bars, and the legs are all joined together in a lsubstantial manner to present a frigid structure possessing great strength and comparatively light in weight.` .The crossbars are arranged slightly below the level of the top faces of the side rails to properly aclcommodate the end board andthe bottom of the Wheelbarrow. The legs 4 are fastened to the frame at thev juncture of the side rails and the rear cross-bar, and,A said 'legs' are braced bythestays 4', suitablyattached tothe legs and to the rear cross-bar. The adjacent front ends of the side railsare provided with suitable boXes or journal-bearings,in which are iitted the ends of the axle 5. The axle and the carrying-wheel 6 may be of any suitable construction.

To enable the` frame to be used in connection with the boards forming the body of a wheelbarrow, I provide the side rails with the loops 7 near the rear cross-bar and with the yeyes lor loops 8 8, which are attached to the vside rails near theirl front ends and on opposite sides of the ground-wheel 6.

The body of the barrow consists of the side boards` 9 9, the ,end board l0, andthe bottom The side boards 9 are lprovided lower edges of said boards, tof'fit into the loops or keepers 7 on the side rails.v The side boards are adapted ,to'rest uponthe side rails '2,and th'e'front ends of said side boards abut IOO 11 of the barrow-body rests upon the crossbars 3 3 of the carrying-frame, between the side rails 2 thereof, and at its front end the bottom board is provided with the lugs 13, which are arranged to fit beneath the front cross-bar 3 of the frame, the rear end of the bottom board being held in place by a turnbutten 14. or other suitable catch.

From the foregoing` description it will be seen that the body of the barrow has its several parts connected detaehably to the carrying-frame in a manner to permit of the ready application of the parts to the frame or their removal therefrom when it is desired to use the carrying-frame in connection with cultivator appliances.

The eultivator attachment consists of a cross-bar or shaft 15, a standard or stock 1G, a clamp lforceupling the stock te the crossbar, braces to stay the lower end of the stock, and one or more cultivater-teeth to be connected to the lower extremity of the stocker standard. The cross-bar er shaft 15 is adapted to be connected to the side rails 2 of the carrying-frame in any suitable way to permit of its ready adjustment. rlhis cross rail or bar 15 maybe loosely and pivotally connected to the side rails 2, between the front and rear cross-bars thereof, se as to allow the crossbar to remain attached to the carrying-frame when the machine is adapted for service as a wheelbarrow. A central hole or orifice 1S is provided in this pivotal rockingcross-rail 15, and through this hole is passed the threaded shank 1S' of the clamp 17, a nut being screwed on the threaded shank to hold the clamp and the standard or stock 1G in place. This clamp 17 has an eye or loop through which lthe steek or standard 16 is passed, and the clamp serves to hold the stock in place on the cross-rail' The stock when adjusted for service is braced by means of the stay-rods 20, which are fastened at theirlower ends to an eye or collar 20 on the stock or standard 1G and which have their upper ends bent to enable said stay-rods to be applied against the inner faces ofthe side rails 2. These upper bent ends of the stayrods are fastened detachably to the side rails of the carrying-frame by means of bolts or other suitableappliances. rl`he construction of the cross-rail 15 and the clamp 17 enables the steek er standard to be adjusted to regulate the height ofthe handles andthe depth of penetration of the tooth or teeth carried by the stock. In the drawings I have shown the stock 1li provided with a single tooth or point 21; butit is obvious that a gang ofcultivatorteeth may be applied to the stock. By loosening the nut that holds the clamp and turning the stock er standard axiallyin the clamp a plow is produced to throw the dirt either to or from the rows, as desired.

To adapt the machine for use as a cultivator, it is only necessary to remove the boards forming the body of the barrow, adjust the standard in the clamp, tighten the clamp, and attach the stay-rods. lVhen it is desired to use the machine as a wheelbarrow, the standard and its stays are detached and the several boards to forni the barrow-body are applied or adjusted in the manner described.

lt will be readily seen that the structure can be converted easily and quickly from a wheelbarrow to a wheeled cultivater, or vice versa, and that the carrying-frame serves in connection with either set of devices.

\"arious changes in the forni and proportion of parts and in the details of construction may be made without departing from the spirit or sacrificing the advantages of my invention.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. A convertible cultivator and wheelbarrow comprising the frame having the tie-bars, 3, and the wheeled axle, the transverse rod, 15, loosely journaled in the frame in substantially the horizontal plane of the tie-bars and provided with a central clamp, the sectional barrow-body with its front and sides fastened relnovably to the frame and with its bottom resting on the side and transverse rails of the frame and provided with a keeper which lits beneath one of said rails, and a cnltivatorstandard adapted for use on the frame interchangeably with the barrow-body and fitted in the clamp and provided with the braces dctachably fastened to the frame, substantially as described.

2. A convertible cultivater and wheelbarrow comprising a frame having its side rails joined by the transverse rails and provided with a wheeled axle, a rocking bar, 15, journaled in the side rails in the plane of the transverse rails and having an obliquely-ar ranged clamp, a barrf'iw-bed y having its front and side walls seated on rails of the frame to which they are detachably secured, and its bottom resting on the rails and rocking bar and provided with a keeper which engages with the frame, and a cultivater-standard clamped in the rocking bar and adapted for attachment to the frame interchangeably with the barrow-body, substantially as described.
