Syd/w H Cle ee BY +7204! a "t t 0871675 United States Patent 3,096,589 GAGE HANDLE Sydney H. Chaffee, Greenfield, Mass, assignor to United- Greenfield Corporation, Chicago, 111., a corporation of Delaware Filed July 10, 1961, Ser. No. 122,806 2 Claims. (Cl. 33-178) This invention relates to handles for gages and more particularly to gage handles for plug type gages.

Handles used for plug gages are generally in the form of rods. Rod shaped gage handles may be double-ended,

such as taper lock or American gage design, to enable gages to be fitted in both ends. A go gage may be fitted to extend from one end of the handle and a not go gage fitted to extend in the opposite direct-ion from the other end of the handle. In order to use both gages, the handle must be completely reversed, rotated 180, to shift from gaging with one gage to the other. Such extensive manipulation is not only undesirable from the standpoint of operational efficiency, but also increases the probability of accidental gage damage caused by dropping and the like.

It is the principal object of this invention to provide gage handles which facilitate shifting irom one gage to the other in go and not go gaging, thereby minimizing the amount of gage manipulation required by the user.

An inherent drawback of the rod type gage handle is that its cross sectional configuration provides a relatively small surface area engageable with a supporting surface. As a result gages carried by rod-shaped handles are relatively prone to damage by being dislodged or knocked from supporting platforms, such as Work tables or benches.

It is another object of this invention to provide a gage handle construction which is not only easy to use but which also provides maximum security against accidental gage damage.

The above and other objects and advantages of this invention will be more readily apparent from the following description and with reference to the accompanying drawing in which:

FIG. 1 is a plan view of a gage handle embodying this invention;

FIG. 2 is a sectional view taken along line 22 of FIG. 1;

FIG. 3 is a plan view of a modified form of gage handle embodying the invention; and

FIG. 4 is a sectional view taken along line *L-4 of FIG. 3.

Referring in detail to the drawing, a gage handle embodying this invention is shown generally at 6 in FIGS. 1 and 2. The handle is in the form of a disk having generally planar and parallel upper and lower surfaces. The height or thickness a of the disk is substantially less than its diameter. As shown, the height a is not less than the maximum diameter of the gages to be carried thereby. This relationship provides a handle having a high degree of stability. Moreover, the gages held thereby are supported clear of an underlying surface so as to avoid any possible damage to the precision surfaces of the gages. The upper and lower surfaces of the disk may be ribbed as shown at 9 for improved gripping. The disk is provided with radially extending bores )10 and 12 which extend normal to the axis of the disk and diametrically therethrough.

The bores 10 and '12 are disposed relative to one another at an acute angle b so that go and not go gages 1-4 and 16 respectively extend radially from the periphcry of the handle at an *acute angle to each other which facilitates manipulation of the handle in changing from the use of one gage to the other gage.

As shown, the gages 1-4 and 16 are reversible plug type gages and are disposed in the bores 10 and 12. The not go gage 16 is inserted more deeply into the bore 10 so that the user can tell at a glance which is the go and which is the not go gage by the relative lengths of the gages extending from the handle. The acute angle b is sufficient to enable the full length of the go gage to be inserted in the member to be gaged without inter-ference from the not go member.

The disk which forms the gage handle 6 is provided with a segmental slot 18 forming spaced opposed wall portions 20 and 22 in which the bores 10 and 12 provide opposed channels 24 and 26 of cylindrical configuration. A clamping screw 28 is disposed adjacent the periphery of the disk and provides means for clamping and releasing the reversible plug gages. The handle may be made of any suitable resiliently flexible material so that when the screw 28 is turned down the channels 24 and 26 firmly clamp and hold the gages in place in the handle. When the screw is backed off, the gages may be easily removed from the handle.

When the work-ing ends of the gages become worn, the screw may be released and the gages removed from the bores 10 and 12 and reversed in end-to-end relation and reinserted in the bores. The clamping screw 28 may again be tightened to firmly lock the gages in place in the handle. The bores 10 and 12 extend completely through the disk so that the gages can be easily removed from the handle by insertion of a suitable tool in the open ends of the bores.

The gage handle shown in FIGS. 3 and 4 is provided for taper lock type gages. The handle 30 is in the form of a disk similar to the one described above. Radially extending bores 32 and 34 are provided through the disk normal to its axis. The bores are tapered to snugly receive the tapered shank of the"go and not go gage members, such as shown at 36 and 38. The bores are disposed at an acute angle to each other and extend entirely through the disk so that the gages can be pushed out of the bores when their removal is desired for any reason. Thus, a worn gage may be readily replaced and the handle reused. The acute angle between the bores 32 and 34 is selected to enable the go gage to be substantially fully inserted, or engaged with, the bore of the part to be gaged.

The relatively large generally parallel planar upper and lower surfaces of handles embodying this invention minimize the danger of the handles slipping or rolling from a supporting table. Opposite surfaces of the disks may be provided with ribs or grooves such as shown at 40, the ribs providing gripping surfaces for the gage handle. While the gage handles shown herein are of circul-ar shape, it will, of course, be appreciated that their periphery could be of any other suitable configuration, such as oval or polygonal.

Handles for receiving taper lock type gages may not be greater in height than the maximum diameter of the gages and may, in some instances, be smaller than the gage diameter. Of course, the handle must be of sufiicient size to accommodate the tapered bores.

Gage handles constructed in accordance with this invention have a high degree of stability for securely holding plug type gages. Moreover, handles embodying the invention provide for maximum gaging efliciency with minimum gage manipulation.
