Description

DESCRIPTION OF THE CONSTRUCTION MATERIALS USED FOR THE SCISSOR SAW AND ORGAN FUNCTION.

The description is made with reference to the figure so? as reported in the project.

CYLINDER F. 1- 2-3- 4 anodized aluminum structure, has two functions: one load-bearing and one control:

1) load-bearing function, movable double-arm holder with claws, skates scissors and belt loop.

2) command function, controls the movable forearm. It has 3 slit grooves: 2 in front and one behind more? the perpei carvings * the skates housing.

PLUNGER F. 7-8-9-10? the working part has an anodized aluminum structure, it acts inside the cylinder with an alternating movement from bottom to top and vice versa. It carries 5 roller skates and? integral with the helical crank, the saw and the chain of the scissors.

ROLLER SHOES; they act in the cylinder-piston interspace and cancel the friction during the operation of the invention, create the space for the nut shaved heads and to expel that part of sawdust that infiltrates between the cylinder and the piston during the cutting phase.

HELICAL CRANK F. 27: It has a steel tube structure with 4 attachment pins and through the slots in the cylinder it attaches to the piston in front and behind at a different height. allows:

1) the ascent and descent of the plunger in line;

2) change the hand and working position of the pruner.

MOBILE BIBRACCIO F. 25: It has an oval steel tube structure, exchangeable claw holder and foot bush, it gets stuck in the cylinder and plays with it with an upside-down pendulum movement and receives stability. and command, these have the following functions:

1) .Stable hold of the branch to be cut

2) constant approach of the saw to the branch

3) increase, decrease, or cancel the cutting pressure.

SCISSOR F32: has a steel structure,? self-opening,? flow rate from the cylinder to which? connected to the handle extension, it is closed by a chain that connects the other handle to the plunger.

SAW WITH FRAME F. 26: Does it have an oval steel tube frame? integral with the piston and attaches to it through the cylinder slot thanks to 4 supports and four manhole covers F.12 and 14.

It has the characteristic of having the saw blade parallel to the frame which allows a very light cut.

COUPLING PLATE F. 20 and 21: It is made of 2 min. Pressed steel sheet, it screws the foot of the double-arm to the cylinder and prevents it from falling backwards.

PAD HOLDER F 18: They are made of aluminum and have the task of locking the pads on the cylinder and making the rollers adhere to the piston body through the notches on the cylinder.

PLATES F 29: They are made of 2 mm pressed steel sheet; one? integral with the scissor arm, have the task of making the scissor integral with the cylinder.

SAW FRAME SUPPORTS F 12: They are made of aluminum, hold the saw frame lying down and are blocked with nuts on the pins that come out of the plunger.

MANHOLE BLOCKING SAW FRAME F 14: They are made of aluminum and are used to block the saw frame on the frame supports.

SINGLE ARM CLAWS: F 22 - 23 - 24: They have an oval steel tube structure, they carry 2 attachment holes to the double sided arm, they are used to keep the ram? to be cut and have a different shape in order to allow the different types of cut since the branches in their growth with respect to the bearing branch take different directions and angles

Claims (1)

CLAIM Is the writer's observation that cylinder and piston must have a stainless steel structure, in order to guarantee greater resistance and lightness such as to make the possibility right? to use an extension to the helix saw with scissors to ensure a cutting of branches at a height close to 6 m. ASSEMBLING THE BLOWER WITH SCISSOR For a correct exposition, reference is made to the figures of the project drawings and to the colored bearers. In 6 shoe holders F.18 12 shoes with 2 rollers are incorporated and are fixed with pins of mm. 8x3 with head outside and open washer nut inside, do these fit into the F.5 shoe housing notches marked in red? of the cylinder? and are screwed with flat head pins coming out of the cylinder whose section? of was 1,5x3mm. Then we move on to the assembly of the pads in the piston. On the pad holder notches we apply the supports that have a height of 8 mm. on which shims can be mounted to raise the pad in such a way as to avoid play in the piston and two pads for support F7-8-9-10 marked in red and with pe: ni with a section of mm. 8x3 with shaved head inserted from the outside, they screw inside the flaps. In the end; you enter the plunger inside the cylinder, slide and check the play of the plunger which must be imperceptible while the plunger sliding must be perfectly free? within his alternate work journey,? it is evident that the plain heads of the nuts find space in the piston cylinder interspace. At the end of the assessment, the 4 holes of the cylinder are matched with the 4 holes of the piston F.7 and 8 F.l and 2, from the back insert 4 pins with an open washer with a section of 14 x 4 mm; these come out inside the yellow FI saw game slot, 4 supports for saw frame F 12 are inserted and screwed tightly making the nut lodge inside the support, in this way even removing the saw everything remains stationary, at this point in? row the frame saw F. 26 and lock it with manhole covers F. 14 and wing nuts. At the end of the work the helical crank F. 27 is mounted, these carry 4 fixed pins through the slits of the cylinder FI and F2 colored in pink, they are made to enter the piston F.7 and F8 and with nuts and washers open they lock inside it . At this point we move on to the assembly of the double-arm, take the plates F.20 and F21 and n. 6 pins, four of 4.5 x 5 cm section and two of 4.5 x 6 mm cm, two pins of 4 x 5, are inserted into the plates at b and are pinned? With wing nuts, then the plates are crossed from the back to the cylinder under the slot saw play and mount the other two pins in a, with another pin of 6 hinges the foot of the double-arm in c and with the other one hinges a bush of 3 cm. with 6 mm through hole. in d, tighten everything with wing nuts and check the inverted peddle movement function of the double-sided arm which must touch the cylinder on the right and left sides without excessive friction. At this point the found? ready to use saw cut. When is the work of cutting with scissors necessary, does the need arise? to have the elisegatrice-scissors pi? light and less cumbersome, for this purpose the double-sided arm and the saw are removed - a very easy operation since it all comes down to unscrewing 6 wing nuts by hand? made this operation you take the bi? plate F.29 one of which? integral with the scissor arm and n. 4 pins with section cm. 5.5 x Min. 5 two pins are inserted into the? the plates in a, are pointed and the plates overlap the cylinder at the end? top, put the other two pins in b and tighten everything, at this point you insert the self-opening scissor which has 2 holes in the half sleeve and a chain in the other handle the half sleeve with two pins locks inside the plate F. 30 while chain B? locks inside the fo with a pin of section cm. 5x6 F. 10, in the lower part of the cylinder, with a pin with a section of 4 cm; 5 x ram. 6 the loop F. 33 is jammed and a belt is made to slide which the operator must bring to collapse. In fact during the cutting work with the scissors? necessary a right stability? of the found, 1) why? facilitates the inforbicamento of the branch; 2) why? does the weight of the helix saw gravitate onto the operator's shoulders in order to allow the user to use it? ro pi? lasting. INSTALLATION OF THE HAND SAW WITH SCISSOR With the right hand you grab the cylinder of the helix saw with scissors above the helical crank F 27 and with the left below it. Identified the ram? to be cut thanks to the double arm (F25), the found is hung. Below the same branch, before loosening the riser, the crank F 27 is raised with the right hand which, being integral with the plunger F 7, raises the saw F 26 to the cutting position, the riser is loosened automatically the double arm F 25 which with its claws F 22 brings the saw blade into contact with the branch to be cut at an optimal cutting pressure. The aforementioned cutting pressure can? be increased by pulling the object slightly downwards, decreased by raising it towards the top? to, completely canceled by lifting upwards until the forearm detaches from the branch. Do you start the cutting operation by alternating the movement of the crank F 27 low up, low up with your left hand or right, until you have cut half? branch; at this point the branch is freed and the heliosaw is brought back with the cutting saw F 26 above the branch in correspondence with the underlying cut and with the same syncontinuous cutting practice until the branch falls. By acting in this way two advantages are obtained: 1) the skinning of the plant is avoided in correspondence with the cut; 2) the fall of the cut branch is identified and no damage is caused. Generally, normal F 22 claws are used for pruning; for very flexible branches, claws F 23, since? these have * two teeth which prevent the branch from coming out; and claws F 24 when cutting branches at very narrow bifurcations. At the end of the cutting of the branches, the tangled twigs are cut or outside the circumference of the crown The double-sided arm is removed to lighten the found, the saw is disassembled to further lighten and not to bother, and the scissor is mounted so? as better specified before, you mount the loop F 33, you pass there? operator's belt and proceed to the second cutting phase The belt is used when cutting with scissors since? during this practice the weight of the helix saw always gravitates to the operator, while during the cutting phase with the saw, the weight of the invention gravitates almost entirely to the plant. In practice, the assembly details can change but what about the invention? domain of patent and invention
