sum n W 4 ma'm MOTOR-DRIVEN SINGLE AXLE AGRICULTURAL MACHINE The invention relates to a motor-driven single axle machine, especially for use in agriculture, horticulture, forestry and has as its object to provide an improvement therein.
In known machines of this type which are guided by rearwardly projecting handles and are used to pull and/or drive implements connected to the frame of the machine, the latter sometimes comprises or is formed by a worm gear housing, the worm gear of which is driven directly or through a drive transmitting means by the motor. The output shaft of such a worm gear is used to drive a work appliance and/or propel the machine.
It is the main object of the invention to construct machines of this type in such manner that their frame can be varied in shape, appearance and gear equipment in simple manner and in substantially higher degree than hitherto for adaptation of the shape and construction of the machine and of the gear transmission between the motor and gear output shaft in such manner that for all different types of work to be effected by the machine and its different tool components an easy guiding and directional steering of the machine and a favorable position of its center of gravity can be obtained while restricting the gear-switching elements to those which are needed by the individual tool components of the machine.
For the realization of this main object, the main feature of the invention provides as a machine frame or part of the latter a worm gear housing of special type which is provided at both ends with entirely identical gear coupling and housing connection means whereby either end of the worm gear housing can be connected either directly or indirectly by an additional intermediate gear housing to the motor.
Preferably said worm gear housing of said special type has coordinated thereto a known right angle gear casing which can be connected by each of its ends to each of the ends of the worm gear casing and preferably also to the motor. Beyond this right angle gear casing further additional partial gear casings with fitting coupling and connection ends are coordinated to said special worm gear casing, at least one further or second right angle gear casing by means which the worm gear casing can be arranged between two right angle gear casings which, moreover, may be provided with different gear transmissions and with a known reverse gear.
According to a further feature of the invention the special worm gear casing is to be provided at its end remote from its worm wheel with a vertical circular attachment projection provided with a lateral toothed rim fitting to an identical laterally toothed coupling rim of the machine guide handle bar allowing an easy adjustment and adaptation of the height of the handles over ground to the different heights of the worm gear casing in the machine frame.
In order that the invention may be fully understood and readily carried into effect reference is made to the accompanying drawings, in which:
FIG. 1 shows a kit of parts from which different types of agricultural of like machines can be composed,

Referring to FIG. 1 of the accompanying drawings, the kit of parts comprises a motor 1 having a gear attachment flange 2, a handle bar 3 having two laterally spaced handgrips 4 of which only one is visible, and a laterally toothed, vertical connecting ring 5, a mounting shackle 6 having a similar toothed connecting ring 7, and a series of interengageable powertransmitting gear boxes and shafts. The series of gearboxes and shafts comprises a right-angle gear casing 8 containing a bevel gear assembly having a ratio of lzl, a second right angle gear casing containing a bevel gear assembly 9 having a ratio of l:3,7, which may be constructed as a reversing gear, a worm gear casing 10 comprising a worm gear with a ratio of 1:23 having the worm gear provided with a transverse output shaft II at one end and a toothed connecting ring 12 at the other, a straight gear casing 13 comprising coaxial input and output shafts, and a further straight gear casing 14 having a laterally provided toothed connecting ring 15. The motor and all the gearboxes are provided with identical fitting connection ends and their shafts with interengageable connections in the form of plugs and sockets which prevent rotary movement relative to one another at any connection.
FIG. 2 shows a self-propelling motorized rotary tiller the frame of which is composed by the motor 1 and the vertically arranged worm gear casing 10, said worm gear casing having its output shaft working as the tool driving shaft 16 at its lower end and with the casing hump projecting towards the rear of the machine. A rotary tiller tool 17 is secured on the output shaft 16. The lower end of the worm gear is covered by a cap 21. The toothed connecting ring 12 of the worm gear casing secures the rcarwardly projecting handle bar 3 on the one side and the mounting shackle 6 on the other side to the machine. A carrier arm 20, which holds a spur 19 at its lower end, is connected to the shackle by its upper end. A guard 18 protects the operator against soil and stones thrown up by the rotating tool 17 when the machine is being used. When used, the tool 17 rotates with its lower part in the earth and produces forward movement. The machine is guided by the operator who holds the handlebar 3 and allows the spur 19 to drag along in the earth.
For an alternative type of rotary tiller, as shown in FIG. 3, the machine frame is composed by the motor I, right-angle gear casing 8 and horizontally positioned worm gear casing 10. The front end of the worm gear casing is closed by the cap 21 and the tool-driving shaft 16 extends beneath and towards the front of the worm gear casing and has the rotary tool 17 mounted thereon. The toothed connecting ring 12 of casing 10 secures the rcarwardly projecting handle bar 3 and also a rear support wheel 22 and the braking spur 19 to the machine. A guard 18 shields the rotary tool 17 rearwards. In use the tool 17 rotates in the earth and produces forward movement of the machine. The user in this case holds the handlebar 3 to guide the machine and is aided in supporting the machine by the support wheel 22.
FIG. 4 shows a motorized plough in which the machine frame is composed by the same elements, namely motor 1, right angle gear casing 9 and worm gear 10. However, the driving shaft 16 of the horizontally positioned worm gear casing is here on the topside of the worm gear and at the rear of the machine and has driving wheels 23 which, of course, are mounted thereon on both sides of the worm gear. The rearwardly projecting handle bar 3 and a similarly projecting spacer member 24 are secured to the machine by the toothed connecting ring 12. The shackle 6, attached to the rear end of the spacer member 24 secures a drawbar 25 to the machine, said drawbar having a plough blade 26 attached thereto. In use, the operator guides the machine by means of the handle bar 3 and as the drive wheels 23 cause the machine to move forward, the plough blade gouges into the earth.
FIG. 5 shows a mowing machine the frame of which comprises also the motor 1, the right angle gear casing 9 and the worm gear casing 10. The latter, however, is reversed in its horizontal position with regard to FIG. 4, having the output shaft 16 on the topside of the rear end of the worm gear casing and carrying again the drive wheels 23. A cutter beam 27 is coupled with the front end of worm gear casing 10. The rearwardly projecting handlebar 3 is secured to the machine by the toothed connecting ring 12. In use the machine being guided by the operator, moves forward self-propelling with the cutter 27 against the surface to be mowed.
FIG. 6 shows a manually propelledrotary mowing machine the frame of which is composed by the motor 1 and the vertically arranged straight gear casing 14 of H6. 1 positioned on top of a horizontal cutter box 29 provided with support rollers 28 and housing a horizontally rotating cutter blade. The handle bar 3, projecting rearwardly from the machine, is secured by the toothed connecting ring 15 of the straight gear casing 14. To operate this machine, the operator simply pushes and guides it in front of him.
In an alternative type of rotary mowing machine, as shown in FIG. 7, the machine frame is formed by the motor 1, right angle gear casing 9, horizontally positioned worm gear casing and the further gear casings l3, 8 and 14 of FIG. 1. The output shaft 16 extends here on the underside of the worm gear casing 10 and has the drive wheels 23 mounted thereon. The shaft of straight gear casing 14 is coupled to the vertical drive shaft of the horizontal cutter box 29. in use the operator simply guides the machine by the handle bar 3 since it propels itself forward.
FIG. 8 shows a sweeping machine the main part of the frame of which comprises the motor 1, right angle gear casing 9, horizontally positioned worm gear casing 10, and second right angle gear casing 8. The worm gear casing 10 has its output shaft 16 on the topside and at its forward end and has the drive wheels 23 mounted thereon. The rearwardly projecting handle bar 3 is secured to the machine by the toothed connecting ring 12. The second right-angle gear casing 8 connected to the forward end of the worm gear casing 10 transmits drive to the drive stub 30 of an. auxiliary frame 31. This auxiliary frame carries a brush 34, shielded by a guard 33 and driven by a horizontal chain drive 32 from the drive stub 30. With this particular composition of the machine frame the weight of the motor 1 and sweeping brush 34 with their coordinated elements balance each other and the operator needs only to guide the machine by means of the handlebar 3.
Various other machines besides those described herein are able to be composed from the kit of gear casings without going beyond the scope of the invention.
