Figures 1 to 3 illustrate an embodiment of the invention for mounting a rotary brush 10, which is located in a housing 12, on a fork lifter or a muzzle loader. The brush is driven by one or more hydraulic motors (not shown) which are connected to one or more attached to both ends of a shaft 14 on which the brush is mounted.

L 89/1 809815/0680

The housing 12 has one or more drawbar rollers 16 and is attached to an upright sleeve 20 by means of a housing extension 22 affiliated. The sleeve 20 is rotatable on an upright shaft 24, which at the top and bottom mounted in assemblies indicated generally at 26 and 28, respectively. The latter are in Fig. 1 because of the partially cut away District visible.

The assembly 26 has two parallel jaws 30 and 32, between which has a bearing 34 at one end of a double-acting hydraulic piston 36. The other end of the piston is attached to a V-shaped frame, which is formed by two diverging arms 38 and 40, of each of which ends in a parallel section 42 and 44, respectively, which are hingedly adjacent to the upper end of one of the two parallel L-shaped side members 46 and 48. The L-shaped members include forwardly extending portions 50 and 52, between which two pairs of vertically spaced transverse struts 54 and 58 or 56 and 59 extend.

The cross braces on each pair are spaced from one another to allow the prongs of a fork lifter to interfere and in the upper strut 56 locking screws 60 and 6 2 are provided for fixing down on the prongs, to keep them in place.

The assembly 28 at the lower end of the shaft 24 has a pair of divergent arms 64 and 66, only 64 of which are shown in FIG. 1 can be seen because of the cut away part. Both diverging arms end in parallel sections 68 and 70, respectively, and these boundaries hinged to the forward ends of the two parallel lower link arms 72 and 74. These extend outwardly of the two L-shaped members 46 and 48 and are at 76 and 78, respectively, at the lower ends of the upstanding sections 46 and 48 of the L-shaped elements are hingedly applied. In turn

is in Fig. 1 because of the cut away part only the lower strut 72 on the far side of the L-shaped element 50 to see. Both struts 72 and 74 can be seen from the top view of FIG.

As shown, the abutments are between the parallel links and the front and rear portions of the assembly are simple bearings, but ball-and-socket connections can be used instead can be applied.

To enable the assembly to be attached to a muzzle loader, a back plate 84 is upright on the back of the two Sections 46 and 48 of the L-shaped members attached. Along the top rear edge of plate 84 is an inverted one Lip 86 is provided which can be bent over the top member of a snap coupling and on the bottom edges of the panel 84 two bearing journals 88 and 90 are provided, within each of which a pin 92 or 94 is located, which is laterally withdrawn can be to allow the journals 88 and 90, with the receiving openings of a breakaway coupling (not shown) to be aligned, which is then disengaged to engage the openings. Pins 92 and 94 are best seen in FIG.

The bearing pins 88 and 90 can, however, also have openings which are simply aligned and into which pins can be inserted. A typical muzzle loader that has a quick release system for attaching to equipment such as her is described here, such is the F.E. Weatherill Limited of Welwyn Garden City, Hertfordshire, England, which is sold under the type designation S3.

The equipment housing 12 can be turned to one side or the other from the straight ahead position as shown in the drawings is to be angularly displaced about the axis of the upright shaft 24.

_{L 89/1} 809815/0680

A plate 96 is attached to the lower end of the shaft 24 between the rearwardly diverging arms 64 and 66 and on the periphery of the plate 96 three or more holes are formed, which have the reference number 98. As best seen in Fig. 1, For example, a second plate 100 is welded to the housing 12 immediately below the plate 96. The plate 100 is also provided with one or more holes which can be aligned with holes 98 so that a (not shown) Pen can be used there to maintain a selected orientation.

As shown in FIG. 2, a double acting hydraulic piston 104 can be fitted between mounting points 106 and 108 will. Retraction of the piston causes the housing 12 to be angled to the right and expand of the piston 104 causes the housing 12 to be angled to the left when the direction of travel which is shown in FIG. 2 by arrow 105.

Stops 110 and 112 extend laterally from the side jaws 50 and 52 and prevent the lower parallel links 72 and 74 from falling below a given position with respect to the Jaws 50 and 52 falling off. This prevents unnecessary downward movement of the equipment housing 12 with respect to the fixed section of the mounting arrangement, which is adjacent to the fork jack or the muzzle loader when the latter is raised is and the brush 10 and the drawbar roller 16 have a clearance to the ground.

Another mounting arrangement for a different rotary brush is shown in FIGS. This other arrangement is specially adapted to be attached to a muzzle loader which has a pair of lower main lift arms 111 and a similar pair of smaller supplementary lifting arms 113 and 114 has. When viewed in plan, the lower arms 111 are through the

27U619 from

upper arms 113 and 114 are partially covered and are not included in FIG. 5 for clarity. However, the closer arm of the two main lifting arms 111 is shown in FIG.

As before, the mounting arrangement has two L-shaped plates 116 and 118. Only the closer plate 116 is visible in FIG. 4.

The two L-shaped plates are at the apex of the L-profile connected by a box section strut 120, and although not shown, an additional reinforcement strut extends transversely between the two downwardly extending ones Arms of the L-profile elements 116 and 118, but this is in the Top view of Fig. 5 covered by the upper box profile strut 120 in front of a view.

At the other end, the rotary brush 122 is located within a housing 124 with a housing extension 126 to which a Sleeve 128 is welded or otherwise attached which is a rotating fitment on a shaft 130 with circular Is section shown in detail in phantom in Figs. The shaft 130 is at its upper end a triangular housing 132 which, although not shown, has a transverse reinforcement rib along the rear straight Edge 134, and a similar reinforcing rib along the inside of edges 136 and 138. The housing 132 is hinged connected to two elongated arms 140 and 142 which are hingedly connected at their rear ends to articulation attachments are indicated generally at 144 and 146, respectively. The pivot mounts extend from the L-shaped members 116 and 118 and are rigidly connected to it.

A reinforcement strut 148 extends between the front ends of the two L-shaped elements 116 and 118 and further beyond, and form laterally extending lugs 150 and 152 which are cut to the elongated

Arms 140 and 142, respectively.

The lower end of the shaft 130 is received in an end bearing, which is only shown in FIG. 4 and bears the reference number 154. This bearing is mounted within the two parallel side jaws 156 and 158 of a channel which has a base 160, which extends on one side of the channel section and forms a triangular plate 162 (see Fig. 5). The base plate 160 rests on and slides over the top surface of a semicircular plate 164, the semicircular Plate extends rearwardly from the central region of the lower rear edge of housing 124.

The channel, which is attached to the bearing 154, is attached to the two diverging rigid struts 168 by means of a pin 166 and 170, which together form a generally triangular frame, hingedly connected. The rear ends of the both struts 168 and 170 are turned inward and extend parallel to and between the two L-shaped ones Elements 116 and 118 and are connected at this point by means of a rigid cross brace 172 and are hingedly connected by means of articulation connections to the lower ends of the two L-shaped elements 116 and 118. One of the articulation connections can be seen from FIG. 4 and bears the reference number 174.

The effect of lugs 150 and 152 is that the struts 140 and 142 are prevented from falling below the position shown in Fig. 4, so that when the muzzle loader arms are raised 111, 113 in the direction of arrow 176, the entire arrangement essentially remains as shown in FIG. 4, however is simply lifted in an upward vertical direction and vice versa. However, if the brush 122 hits the ground, so the housing section 126 acts on the underside of the housing element 132 and prevents the latter from continuing to move into Move downward direction. Any continued further downward movement of the muzzle loader arms 111, 113 causes one

Rotation of the parallelogram connection formed by the struts 140, 142 and the triangular gesture struts 168, 170 becomes, with respect to the L-shaped elements 116 and 118, and the Struts 140 and 14 2 stand out from the approaches 150 and 152. In this state, the brush can be said to be completely floating and follows rough terrain without any tension conveyed by the connection to the muzzle loader arms 111 and 113.

As shown in Fig. 5, the triangular plate 162 has an opening 178 through which a pin (not shown) can be countersunk and the plate 164 is provided with a number of similar openings, one of which is shown at 180 and which can be aligned with the hole 178 depending on the orientation of the housing 124 with respect to the normal direction of travel, which is indicated by arrow 182.

Force actuation of the orientation of the housing 124 is achieved by means of a double-acting hydraulic piston 184, which at 186 to the strut 168, and at 188 to the rear of the housing 124 is hingedly connected.

The housing 124 is reinforced by means of rearward extending Housing sections such as 190.
