the essential parts needed and in this instance 2 are the mountains and 4 is the lifting on an off handle and 3 are the swivel bolt holes for connecting with the handle lever which is 5 and 8 and these carrier plates can also be incorporated as a double rail Referring to Fig B is the handle lever which is indicated 5 and 8 is fixed to the carrier plate 1 on mountain 2 whereby the carrier plate 1 of its crossbar 9 will carry the legs 14 to actuate there and the lifting locations 7 which can be round or elongate are used for machine lifting while the handle 8 can be used for single or double hand manual lifting and handling and laying for example on a curbstone bed Referring to Fig C the crossbars 9 will be fixed center or relatively centre and square to the ends of the carrier plate 1 which will allow the legs 14 to fix there at swivel holes through 10 Referring to Fig D the round tube 11 will be fixed to the leg linkage 12 at its upper end from swivel hole 13 and the swivel tube lla will be placed on the swivel bolt 20 middle in order to allow the handle lever at 5 to move and roll along it to actuate while lifting at 8 Referring to Fig E this leg linkage 12 is fitted with round tube 11 at its upper end to link up with roller unit 25 and legs 14 through swivel holes 13 and 15 with swivel bolt 20 to actuate via lever handle 5 at 8 when lifted will roll via swivel tube 1 la on handle lever at 5 against roller tube 1 la on bolt 20 Referring to Fig F is the leg 14 which will fix to the crossbar 9 and the leg linkages 12 through swivel holes 13 and 15 to actuate accordingly for the whole product to essentially function for the legs to automatically open by weight ratio in readiness for placing the tool or lifting off via the lifting on an off handle 4 Referring to Fig G the soft adjustable aluminum leg grabs 17 when fixed to legs 14 will accordingly actuate inwardly via the lever handle 5 and 8 through the linkages 12 through swivel hole 13 on swivel bolts to make contact with say a curbstone 21 to securely hold it for lifting placing and bedding of which aluminum can be extruded in angle or T section or tube and so on to form these aluminum leg grabs Referring to Fig H the tool when lifted at handle lever 5 at 8 on mountain 2 through mountain swivel hole 3 or lifted via the machine lifting and handling locations 7 will actuate to move the legs 14 upwardly against lever handle 5 via 8 against the roller tube 1 la on the roller swivel bolt 20 in order to actuate the legs on plate 9 through swivel holes 10 and 15 for the legs 14 to move inwardly at their distal ends for the aluminum leg grabs 17 to make contact with say a curbstone 21 to hold it there while lifting placing or bedding Referring to Fig J the lever handle at 5 will swivel on mountain 2 from below the carrier plate 1 base line to move upwardly which will lever against the roller tube 1 la on swivel bolt 20 to move the legs 14 upwardly to swivel on the cross plate 9 to move the distal ends of the legs inwardly for the aluminum leg grabs 17 to make contact with say a curbstone 21 to hold it there while lifting placing or bedding which will also work transversely on a configuration of two location contact points and or 4 and of which is a self adjusting and is a moveable under lever configuration and system of which the near correct ratio and parameters are essential for this system to work at any near low sizes and on any near exact scaled up sizes of which will allow for any of my essentially designed legs to fit most sizes and shapes of block pipes slabs lintel copings sills heads steel aluminum wood and concrete sections and similar and so on Referring to Fig K the spacer roller bar 22 is either welded of bolted onto the lever handle 5 to keep the central space under the roller unit to actuate there when the handle lever 5 is lifted at 8 Referring to Fig Ka a the spacer roller bar or plate 22a is either welded of bolted on to the lever handle 5 to keep the central space under the roller unit to actuate there when the handle lever 5 is lifted up against roller tube 1 la via 8 Referring to Fig L the lever handle 5 are fitted with forked tangs 23 welded or bolted there to fit over mountain 2 to swivel and actuate there and I note here that all lock nuts should be just off tight in order for all parts to swivel Referring to Fig M the lever handle 5 is fitted with forked tangs 23 welded or bolted there that will fit over the carrier plate mountain 2 to allow the lever handle 5 to be lifted at 8 to actuate against and with the whole roller unit which must have enough space and to also move on the roller bolt to and with roller tube 1 la and linkages 12 with roller tube 11 attached Referring to Fig N the forked handle lever is indicated 23 and welded onto 5 and the roller unit is indicated 11 a is surrounding it with linkages whereby the forked handle lever 5 when lifted at 8 will move the tangs 23 fitted to lever handle 1 against the roller tube 11 a to actuate the equipment for the system Referring to Fig 0 as an alternative carrier plate 1 is fitted with mountains 2a welded each side or bolted there to carry any handle lever 5 to swivel between them Referring to Fig P the carrier plate shows the four end mountains 2a fitted to carrier plate I Referring to Fig Q the double mountains 2a on carrier plate 1 allows for a handle lever 5 to slot between the mountains 2a and bolted through to swivel there which allows the lever handle 5 to be lifted and to actuate to swivel within the roller unit against roller tube 11 a to actuate the equipment for the system Referring to Fig P is a plan view of the double mountains 2a on carrier plate 1 Referring to Fig Q is a through view of the double mountains 2a on carrier plate 1 under the roller unit Referring to Fig R is a through end view of the forked handle levers 23 on handle lever 5 in its start position when lifted at carrier middle handle 4 is in readiness to place over say a curbstone 21 whereas the weight of the roller unit up to 11 a with inside legs at the swivel upper end by a correct essential calculated weight that will force the short ends of the upper legs down to open the legs 14 at their lower ends as shown at the legs aluminum grabs 17 to open out in readiness to place it and I would also like to note here that the longer the lever handle there will be more gripping power at the roller unit and hence the aluminum leg grabs and this can also be achieved in a scissor configuration for this equipment and system which can also be used for any scaled up versions to cope with heavier products and will also work from the inner side of the carrier plate including for using chains or heavy duty straps and so on as will be described herein and in combination of my essential parts Referring to Fig S is a through end view of the forked handle levers 23 on handle lever 5 will close to a position when placed onto say a curbstone 21 via the carrier plate 1 middle handle 4 for the weight of the carrier plate to cause the legs 14 to swivel inwardly while the short ends of the upper legs will move upwardly to close the legs 14 at there lower ends for aluminum grabs 17 to locate the curbstone in readiness to lift the handle at 5 at 8 that will swivel and actuate against the roller unit at roller 11 a to grip and hold the curbstone at aluminum grabs 17 while lifting placing or bedding of which I call a diverse over grab system of equipment which will work transversely on a configuration of one or two location contact points and or a 4 location contact of which is a self adjusting and moveable under lever configuration and system of which the near correct ratio and parameters are essential for this system to work at any low sizes and on any near exact scaled up sizes of which will allow for my various designs of legs to fit most sizes and shapes of blocks pipes slabs lintels copings sills heads steel and aluminum and concrete sections and so on Referring to Fig T is a plan view of another of my many alternative adjustable aluminum leg grabs 17 that can be fixed to the leg 14 whereby the thicker end section will face and contact the object lifted to hold it while being lifted and the front thicker face of 17 can be serrated or similar and so on to allow more grip while lifting and or machine or manual handling Referring to Fig U the carrier plate 1 is plasma or laser cut fabricated and so on with a notch 3a which will allow the cross plate 10 to joint in to be fixed or welded there with further chamfers as depicted 3b for the other weld to be inserted below the material surface for stronger fixing Referring to Fig V an alternative handle lever with forks 23 as described earlier Referring to Fig's Was 5a and 5b are side views of some of my single or double hand handle grips that I can chose to manufacture to fix over or onto the distal end of handle at 8 such as handle lever 5 at 8 at Fig V and other of which is designed in soft grip materials or metal which can be bolted or glued or friction fitted or welded fixed and so on Referring to Fig's X is a side view of the lifting tool with swivel gears and legs situated on the inner side of the cross plate 9 which cross plate is fixed to carrier plate 1 at its notched location whereas you can see alternative handle levers 5 are fixed to mountains 2 which has hook or strap of chain and so on lifting holes 7a for machine lifting and maneuvering whereat the handle levers are machine or mechanically lifted at 7a will actuated under the roller unit as previously described herein Referring to Fig's Y and Z are side views of other laser or plasma cut leg designs for lifting other products such as a pipe or paving or coping and so on as described herein Referring to Fig AX is a side view of the lifting tool using only one double end which usually two of these units can also be used on each end of a long section for lifting such as wooden sleepers or lintels and so on using the same principles described herein for this lever 26 to be lifted at its distal ends of which can also be adjusted or angled to suit any person including at adjusting means 26a and also a tube could be fixed on the handle or through the handle lever at 26b to create a crossbar handle Referring to Fig BX and CX and DX are side views of other essential components by using only one singe end with another leg section configured to it for such as lifting bricks or a block or a slab and so on which will also assist for laying block and slabs and so on is better explained at Fig EX following Referring to Fig EX is a side view of this alternative configuration of lifting tool in quarter form of which when the handle lever 5 is lifted at its distal end it will swivel on bolt at 15a to actuate the end at 16 to move inwardly to grab the product such as bricks indicated 27 with soft aluminum grab pads 28 which are described in other forms herein but not drawn here and the adjusting holes 9b when fitted with bolts through leg 14a at 9c will allow the leg 14a to be adjusted to be extended or shortened to fit most products in its range and the holes in the lever as at 15a through 15b will allow half adjustments to allow finer incremental adjusting for the tool to fit any product in a good near fit before lifting Referring to Fig FX of the leg 14a is fitted with an alternative soft aluminum grab pad 28 of which can also be fitted to the handle lever 5 at 15a through 15b and also other configurations of aluminum or similar material grab 28 can be fitted likewise Referring to Fig's GX 17as is a side elevation of the self adjusting swivel grab that will swivel on bolt at 18 through the tube shims shown at 17ass and on plan view at 17ap through shims 17ass which is shown at leg 14 at its distal end whereat the self adjusting swivel grab 17as will swivel at 18 whereby the face of the grabs inner side will abut the object lifted face on of which grab face will include serration of indentations and so on to its inner face side to give more friction and grabbing power contact with any clean and dry products that are lifted Referring to Fig IIX is a side view of the equipment in action whereby the handle lever has been lifted to actuate the legs inwardly whereat the self adjusting swivel grabs 17as have self adjusted on their swivel bolt at 18 for their inner faces to meet with both sides in this instance of lifting an edging curb 21a to contact its front and back face in order to lift it and to allow for its maneuvering and bedding in line on its mortar or concrete bed Referring to Fig JX is a side view of a forked handle lever essential parts whereas 6a is plasma or other cut shape with a rounded distal end which section is a narrower end width than the main handle lever 5 is to allow the welds of the lever to be below the top of section 5 that will not interfere with its function against the roller tube when the unit is in action for lifting and placing as described herein and I also note here that this appliance can be the same for any lever or other essential part in this essential design of product.
Referring to Fig ICX is a plan view of a forked handle lever essential parts whereas 23a is placed against and with handle lever 5 whereby welds at 26a and 27 are all in corner welds to shroud the whole end and below or in a position that will not interfere with the products actions as described herein Referring to Fig LX is a side view of a forked handle lever which is in corner welded complete whereby you can see there is no weld protruding above or below the widths of handle lever 5 and the end weld as seen is also an in comer weld which is neatly positioned and such welds will also give at least 50 percent more strength than that of any of other types of welds and in a position that will not interfere with the products actions as described herein and I also note here that these essential parts can be attached by other means such as nut and bolt and so on and also the lever handle end as at 8 can have configurations to match and for the fitment of dip molded type soft handles and the like made from polypropylene and the likes or simple tube designs and so on "Special Notices: Technically, it is understandable that any person's confidential developments sometimes takes many weeks and months and sometimes years to achieve a definitive design and while working with the new cutting plasma and laser technology and so on of the industry as it progresses and this takes an enormous amount of designing and trial and error which is evident in the progression and the manufacture of this new design because the variables and functions of each essential part is significant and novel and so it is essential that any person could confidentially register any essential designs at their early stages at the IPO in order to gain a priority of its first invention or art at that date and at any stage of development afterwards so that nobody could say after that date they had thought of and drafted or found prior art to challenge this invention or design after that date
