The present invention relates to a standard bit machined ratchet wrench, a tool and a tool bit using its extension.

Virtually all auto mechanics, mechanics, repairers, farmers and others who want to repair a machine are in their possession a standard mechanical socket, usually consisting of a ratchet socket wrench and a head of bolts and nuts and at least one or two sockets. It is equipped with sockets of various assortments to fit the ranch extension.

A more complete set of sockets would also include both standard driver sockets and Phillips screwdriver sockets, sometimes including universal joints as well.

Standard sizes for socket sets include 1/4 ', 3/8 ", 1/2" and 3/4 ". 1-inch socket sets are readily available for specialized use, such as large leveling equipment and agricultural machinery. It is done.

The dimension description of the socket set, of course, describes the size of the rectangular drive bag inserted into the socket to allow the drive tool to transfer torque from the drive tool or ratchet wrench to the socket.

In practice, standard machine socket sets are one of the most common hand tools commonly used today.

Those who need to use tools to repair mechanical objects are as good at using standard sets of sockets as carpenters are at using hammers.

Tabs and diesets for threading and repairing nuts and bolts commonly used and sorted, hand drills for drilling non-metallic objects, such as fence posts and plastic products, and cut bolts embedded in the screws of the last female threaded holes Other tools are also generally classified, such as hand tools that include reversing threaded tips that are inserted into the drilled holes of the tool.

Reversing threaded taps are sometimes called easy.

It is twisted into a hole drilled in the cut bolt in the direction of rotation opposite the direction of the cut bolt.

Inside, the twisted reversing threaded tab releases a new screw in the opposite direction and the resulting bolt transfers the torque from the female threaded hole in which it is inserted to the bolt cut in the direction of its rotation.

Each of these hand tools, hand drills, taps and die sets, and reversing threaded tips have their own distinct and independent origins and development history. As a result, the driving tools for each of these devices are different. Both the tab holder and the die ring holder are different from the standard socket ratchet wrench.

They are also different from the standard manual drills used by carpenters to drill holes in or through wood. Reversing threaded taps are usually found in various other forms of devices for cutting and bolting them.

No drive tool is interchangeable with another and each wants the user to learn a new set of skills to use the tool effectively.

Using a standard socket ratchet wrench to tighten the bolts of an auto engine requires a fairly different set of skills from those who require skillful handling, drilling a hole through a fence pole and one frame member of the farm equipment. You want to use the hand drill effectively to rescrew the screw.

For agricultural machinery it is particularly useful to make a set of tools adapted for use with such standard machine socket sets described above for use in retrofitting.

When many parts of the farm machinery are destroyed, many parts of the farm equipment cannot be moved from the remote location to the orderly retrofit. In such a case the debate improvement in order to approach the cut bolt requires substantial time consumption and dismantling of the machine.

By using the unique shape of the socket tool, integrated coupling and socket wrench extension bars, if the conventional drive tools for drills, taps, dies and reversing threaded taps are used, the repairman can The broken part can be reached without disassembling the machine

The use of such a tool set in automotive repairs may or may not require the removal of ancillary equipment even with the removal of the engine block from the vehicle to obtain the space of access required for the use of conventional drive tools. It is easy to redraw the drain plug hole or bolt hole of the engine block if possible.

Other applications include drill frame members, radiator covers and sheet metal.

Incidentally, since none of those tools can be exchanged, a complete set of tools requires more lists of various drivers, as do miscellaneous bits and sockets.

Standard machine socket sets make excellent ability to apply torque or torque to items to be utilized in their unique design form. An important mechanical benefit is obtained through the use of standard socket ratchet wrenches. Additionally, socket extensions and sacks which may be installed to extend the ratchet wrench's sacks away from or difficult to reach in order to effectively axially rotate the socket ratchet wrench from one direction to another without the use of a powertrain. It is even more easily accessed through the use of integrated couplings which can also be installed on or in extensions thereof.

Nothing of this type can be found in hand drills, taps and die sets and drive tools for reversing threaded towers.

Miller Patent No. 3,508,455 discloses a combination tool made for the use of specialized socket wrenches to improve the ability to apply torque to screwdrivers or socket wrenches.

ACEVEDO Patent No. 4,235,133 is a reverse winding that surrounds a tool sack and sleeve so that when the other end of the coupling rotates in one direction it drives the tool and it does not drive the tool when it rotates in the other direction. Announces a coupling for the tool receptacle at one end to receive a pair of springs selectively

Canadian Patent No. 522,892 discloses a design for a screwdriver in which a socket is made at the end of the handle to grant the power sacks of a mechanical socket ratchet wrench so that additional lock force can be applied to the screwdriver.

French Patent No. 1,116,742 discloses an adapter for the use of screwdriver handles with interchangeable screwdriver bits, and Swedish Patent No. 136,361 announces the use of sockets with standard power reel chucks.

None of the prior art discloses a tool bit that uses a reversing threaded tap to apply a hand drill, thread and cut, or to remove a cut bolt whose drive tool is a standard machine socket first wrench.

In addition, no prior art discloses tool bits that are adapted for use in remote or non-adjacent positions through the use of inherent design shapes of socket wrench extension bars and general couplings.

The tool bit of the present invention is for use with standard mechanical socket ratchets and extensions thereof.

It is attached to one end and has a tool axis for axial rotation with the socket accommodated in size and shape to accept a standard size bag of socket ratchet wrench.

At the other end of the shaft, either a drill, a tab for threading a hole, a reversible threaded tab for removing a cut bolt, or a cylindrical socket ring for holding a die of standard size for cutting a screw in the bolt Is located.

In the case of a round socket ring extension to limit the volume of space for receiving the threaded bolt portion of the bolt passing through the die, a brace is provided to maintain the cylindrical socket ring in the common axis and in relation to the tool bit axis. Is located.

Tool bits formed as drill bits in connection with certain reference numerals in the figures are generally indicated by reference numeral 10 shown in FIG. The shaft 9 attaches to one end socket a cover 14 defining a socket 15 for receiving a bag of standard socket ratchet wrenches.

The detent 16 is made to receive a detent ball of a packet wrench bag. The hand drill 17 is attached to the other end in a straight line in the direction.
