Lathe Chuck WrenchesOne of the most common acci-

dents on lathes or other machines involves a chuck wrench or key which is thrown from the chuck. This happens when someone forgets to remove the wrench from the chuck before the machine is turned on.

A spring-loaded or self-eject-ing chuck wrench can be used on lathes or other machines equipped with manually adjusted chucks. The spring-loaded sleeve ejects the wrench from the chuck after each use. This wrench is

engineered and designed to pro-vide proper loads for self-removal of the wrench weight.

Sliding Lathe ShieldsThese sliding lathe shields are

furnished in four different sizes. They are constructed of high qual-ity 12-gauge steel, with a polycar-bonate window. These shields are available for operator protection on large standard lathes, CNC machines, and OD grinders.

The shields are designed to fit lathes with chucks up to 48 in. in diameter. Four adjustable flanged mounting posts are provided for easy mounting. These posts are used to securely mount the shields ball-bearing carriage to the top of the headstock, as illustrated. This means the posts can be attached without interfer-ing with any part of the equipment housed within the headstock.

These sliding shields slide out-of-the-way over the headstock, allowing the operator access to the point of operation for loading and unloading workpieces, chang-ing tooling, changing chucks, removing swarf, etc. They are painted yellow and are furnished with handles.

When ordering these sliding shields, check lathe dimensions and reference drawings. Special sizes are available on request.

Crosslide-Travel Lathe ShieldsThese lathe shields mount on

and travel with the crosslide for protection when machining long workpieces. The steel structure provides protection from flying chips and coolant. The window permits visibility into the point of operation. The front portion of the shield hinges up for access. These shields are ideal for lathes with long beds. Special sizes are available on request.

Small Steel Lathe Chuck ShieldsThese steel chuck shields are

fabricated of 18-gauge steel and can be used on smaller lathes that have up to 18 1/2 in. diameter chucks.

Each shield is furnished with a 1 in. x 13 in. mounting rod which can be cut to length if required. This mounting rod is fastened to the headstock of the lathe. The mounting rod is also used to hinge the entire shield. The shield can be lifted and swung up for quick and easy access to the chuck and the part being machined. These shields are painted yellow. This shield includes a polycarbonate window which permits visibility into the point of operation.

Various types of mounting brackets are available.

Large Steel Lathe Chuck ShieldsThese fabricated 18-gauge steel

chuck shields can be used on large lathes that have chucks up to 47 in. in diameter. They are double hinged for access to the chuck, workpiece, and tool. The front hinged portion can be swung up for workpiece changes, and the entire shield can be hinged back for changing chucks.

Each shield is furnished with a mounting rod, plate and support bar for mounting the shield to the face of the headstock. The rear mounting bracket hinges the en-tire shield, and the side mounting bracket supports the shield in its normal operating position. These shields are painted yellow and are furnished with a handle.

Transparent Lathe Chuck ShieldsAn efficient lathe shield has to

give maximum operator protection with good visibility and fast, easy access to the workpiece. These shields fulfill these requirements.

These lathe chuck shields have a semicircular shape made from impact-resistant, transpar-ent polycarbonate. The shields themselves are attached to a 1 in. zinc-plated extension tube. This tube is inserted into one of the mounting brackets described on the next page. The shield assem-bly does not include the mounting bracket.

The semicircular shield covers half the circumference of the lathe chuck because it is mounted an equal distance from the chuck center.

Access to the chuck and workpiece is quick and easy. The shield is lifted up and out of the way for the operator.

The shield size depends on the center height of the lathe and the diameter of the chuck. On lathes with a center height up to 7 in., there is a small variation in diameter between the 3- and 4-jaw chucks; therefore, one size shield will do the job.

On lathes with a center height in excess of 7 in., there is a greater variation in diameter between the chucks; therefore, it is advisable to use two different size shields to provide adequate protection.

Mounting Brackets for Small Steel and Transparent Lathe Chuck ShieldsThe zinc-plated extension

tube, to which the polycarbonate and steel shields are fastened, is mounted to the headstock of the lathe by a mounting bracket.

Bracket StylesThere are two principal types of

mounting brackets available. Type A is used for mounting to the top or the side of the headstock.

Type B is used for mounting to the inside face of the headstock.

For difficult mounting condi-tions, bracket Type A1 may be used. This bracket incorporates a

telescopic height adjustment (up to 2 in.) and can be swiveled up to an angle of 90 as required.

Bracket Type B2 is a two-socket mounting. It can be fastened to the face of the headstock where shields with different diameters may be used. It accommodates 3-jaw and 4-jaw chucks. The inner socket is used for the 3-jaw chuck shield. When changing over to a 4-jaw chuck, the shield is removed from the inner socket and replaced by a larger diameter shield inserted into the outer socket. This accom-modates the 4-jaw chuck.

Bracket Usage The small steel and transpar-

ent lathe chuck shields can be interlocked to the motor starter. When the chuck shield is lifted up, the contact on the switch is opened. This causes the machine to stop. The switch is attached to a heavy-duty mounting bracket.

This interlocking bracket as-sembly includes mounting bracket 231003.

Bracket type A1 For extended mounting to the top or side of the headstock.
