Application August 17, 1944, Serial No. 549,895

1 Claim. (Cl. 33-174) This invention relates to a surface or checking plate structure.

The chief object of the present invention is to provide such a structure which is adapted for substantially universal use, eliminates excessive wear and make available substantially the entire surface area of the plate proper for work reception.

One chief feature of the invention resides in providing an undercut anchoring channel or groove in the plate in juxtaposition and parallel to a side face exactly transverse to the work supporting face of said plate.

Another chief feature of the invention resides in providing a side face on said plate exactly transverse to the work supporting face thereof and arranging said side face for riser plate and like mounting thereon and at any desired inclination.

Still another feature of this invention resides in the tail and head stock centering units to be supported by said plate in coaxial alignment.

A further feature of this invention resides in the adjustable center bar.

Still a further feature of this invention resides in the angle plate and its mounting.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim.

In the drawings:

Fig. l is a perspective view of the plate proper and aligned centering bearings applied thereto.

Fig. 2 is a transverse sectional View taken on line 2-2 of Fig. l and in the direction of the arrows.

Fig. 3 is a perspective view of the plate proper, a riser plate applied thereto, and an angle plate adjustably mounted upon the riser plate and inclined to the plate proper.

Fig. 4 is a transverse sectional view taken on line i-ll of Fig. 3 in the direction of the arrows.

Fig. 5 is a perspective view of the plate proper, a center bar adjustably mounted thereon and inclined to the plate proper, and the aligned hearings mounted upon said center bar.

Fig. 6 is a rear elevational view of the center bar and plate proper connection.

Fig. 6A is a similar view of a semi-circular type of center bar.

Fig. 7 is a perspective view of another embodiment of the bed or base plate with riser plate and aligned bearing structures applied thereto.

Fig. 8 is a similar view of the same base plate from the opposite direction and with an angle plate and angle bar applied thereto.

In each of the figures of the drawings ill indicates the base of a checking plate having the substantially perfect plane surface II on top l2. One edge 13 defines the upper end of side face M exactly at right angles to surface ll.

Parallel to face l4 and herein fairly close to edge l3 there is formed in the top H a channel or groove l5 which has one side undercut as at Hi. This may take many forms, and if desired, said opposite side may be undercut, so the channel is keystone sectioned or T-shaped as desired.

A head stock bearing l1 and tail stock bearing it may be associated with the aforesaid as illustrated in Fig. 1 and more particularly in Fig. 2 wherein 19 indicates the plate face of base 2!] having at right angles thereto side flange 2! with face 22 transverse to face I9. This stock is seated on plate portion top H with faces 22 and i4 abutting and faces l9 and H abutting.

For stock retention a clamping hook 23, having angular end 24 seated in the undercut groove, extends through angular bore 25 and the threaded outer end of said hook mounts nut 26. Tightening down on the nut draws the stock so the four surfaces abut as described and such hook and nut rigidly clamps the stock to the plate.

Obviously the simplest form is to have such undercut groove coextensive with the surface H and thus the two stocks can be mounted from opposite ends of the groove. The axial distance therebetweenis adjusted as desired or required and the clamp nuts turned down. Since flange it prevents turning but one clamp is required for retaining each stock bearing. The work in Fig. 1 is indicated by letter W. One of the clamps (98) may be of fixed center type and the other (ll) may be quick axial adjustable type, see part 21.

From Fig. 1 it is obvious that substantially all the area of surface II is available for use and only the back edge portion is utilized for stock mounting purposes.

In Fig. 3 the plate proper has projecting upwardly from surface I l a riser plate 30 with surface 3i exactly transverse to surface H. The base Ill includes mounting face 29 transverse to surface H and the face includes diagonally opposite threaded holes 28a and 28?) therein (see also Fig. 4').

Riser plate 30 includes matching openings 32a and 32b therethrough. Bolts 33a and 33b extend through the respective riser plate openings and thread into the respective base openings to 3 secure the riser plate to the base and with the two surfaces exactly transverse to each other. Work may be clamped to the riser plate and checked with reference to the surface ll.

Herein, however, for purposes of illustration, the riser plate is centrally apertured at 35, see Fig. l, and same, on surface 3!, is countersunk or bored as at to form a seat to receive boss 3'! on angle plate 38 having two transverse faces 39 and i0 and a pair of reenforcing webs or flanges 4 l.

Coaxial with the boss 3'! is the aperture 42 and same registers with aperture when the boss is bore seated. The boss and seat are circularly shaped so that the angle plate may be positioned with face 39 at any desired inclination to surface E i. Means 63 extending through both apertures clamp the riser plate and angle plate together in adjusted relation. To the angle plate the work W again can be clamped.

Reference will now be had to Figs. 5 and 6 where, for purposes of illustration only, the coaxial bearing application is repeated. However, herein these bearing units are similarly secured to an adjusting bar having formed thereon two angular (90) faces 5| and 52 with groove 53 therein undercut as at 53a. Face 5! abuts face 29 on base l0. Bar 50 may be used alone With the bearings when desired by merely resting same on plate surface I i.

For angular adjustment bar 50 includes aperture 54 and quadrant portion 55 recessed at 56 for lightening the bar. This quadrant has arcuate slot 57 therein coaxial with aperture 54. Means 58 and 59, extending through aperture 54 and slot 5?, are threaded into apertures 28a and 201), respectively, and clamp the bar in the inclined position desired, the bar pivoting on anchorage 58.

Naturally if the bar is to have tilting movement to left, opposite to that shown in Figs. 5 and 6, the quadrant will extend oppositely. If it is desired that the bar be capable of adjustment either to the right or left, the quarter circle portion, instead of being approximately 90 will be replaced by a semi-circular portion of approximately 180", and the coaxial arcuate slot will be correspondingly elongated and naturally extend through or across bar 50 at the mounting end thereof and as shown in Fig. 6A.

In all of the foregoing embodiments, it will be observed that when the stocks, slotted bar, riser plate and an le plate are base plate mounted saving of set up time will result. Also, note that such assemblies leave the major portion of the base plate area available for working space. Also, note that because certain of the assemblies are of side mounting type, the Wear on surface H of heavy parts is eliminated or materially reduced. The present invention also is substantially universally adaptable in character.

In Figs. 7 and 8 of the drawings the base plate H0 has the top portion H2 with top face or surface Ill. The back includes central mounting pad l20 and two end coplanar pads I60. This plate has the rear surface H 'i, surfaces H4 and HI having edge H3 therebetween. Parallel thereto is the undercut groove l i5.

At each rear corner and exactly transverse to pads I00 and surface lil are the transverse or side pads I and Ill. The latter is coextensive with the side of the base plate.

Herein pads I00, central pad I20 and side pads H0 and ill have coplanar grooves or horizontal key ways l6l, E2093, I12 and H3, respectively,

for utilization in squaring a riser plate or similar adaptation to bring any duplicating application back to original position. The several pads may be drilled and tapped suitable for the application of bolts, bushings, pins or the like for application mounting. Same, however, except for the center pad holes are omitted herefrom for clearness.

When two riser plates, see Figs. 3 and 4, are corner mounted, the result is a true angle therebetween which can be used in such cases where the work requires triple transverse plane reference.

In Fig. 8 there is illustrated an angle plate having base 200 resting upon surface III. This plate has riser portion 20!, slotted as at 202 to receive a base 203 vertically slidable in said slot and rigidly secured at the adjusted elevation. This base rotatably mounts the circular portion 200 having a pair of arcuate and coaxial slots 205 therein. Screws 206 carried by base 203 clampingly lock base portion 204 in the angularly adjusted position upon base 203.

The latter has indicator 201 (a line) to cooperate with the angle scale 208 on the beveled face of base 204. Rigid with said base is the elongated bar 209 similar to bar 50 except herein the quadrant or semi-circular adjustable anchorage is omitted. Mounted in groove 210 are the longitudinally aligned bearings 2H and 2| 2 identical, if desired, to bearings l8 and I! re spectively, see Figs. 1 and 5.

Herein the lower face of said bar 209 has a pair of spaced notches 213 therein which have two transverse faces 2|4 and 2l5 and the sloping throat face 2l0. In each notch is secured a bearin cylinder 2| 7 by means of a filister head or Allen cap screw 2| 8 which extends through the cylinder into the bar and has its head countersunk in said cylinder. The longitudinal axis of this screw is at 45 to the faces 2I5 and 214 and intersects the vortex of the 90 angle formed thereby.

The depth of the notch 2| 3 is approximately 7 that of the radius of cylindrical bearing member 2H. This positioning does not interfere with the utilization of said bearing member over a wide range of angle adjustment.

The two cylinders are equidistant from the central pivotal axis of bar 209, and spacing block or gauge 220 is equivalent to the sine of the desired angle when the lower cylinder rests upon surface Ill and the lower end of gauge block 220 also rests thereon and the upper cylinder Y rests upon the opposite end of said gauge block.

The foregoing constitutes a universal sine bar center which has angular adjustment of 45 in either direction with reference to the surface III. This structure is particularly accurate and capable of rapid adjustment for concentricity and angular dimensioning and eliminates the necessity of using female auges.

The key way can be so dimensioned that the universal sine bar center may be mounted therein instead of the angle plate 200-20! illustrated, provided the mounting pad keyway be slotted as the angle plate is slotted at 202. The groove H5 in the top H2 also may be slotted for the same purpose.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in 76 character.

The invention claimed is:

A checking plate having a pair of transversely positioned faces, means abutting one face and projecting upwardly from the other face, and a plurality of clamping structures securing said means to that one face, said means at the end abutting said one face having a laterally projecting portion with an arcuate slot coaxial with one clamping structure and operatively associated with the other clamping structure, the said means further including a pair of transversely positioned faces and a groove in at least one of said last mentioned faces and parallel to the other of said last mentioned faces, the groove being undercut, means having two transverse surfaces arranged in reentrant formation for abutting engagement of the two last mentioned transverse faces, and a clamping structure having a portion seated in the undercut groove for clampingly securing the last mentioned means to the first mentioned means.
