ADJUSTABLE GAUGING DEVICE Filed Nov. 5, 1964 INVENTOR. Walter J ZajkowsJcz' United States Patent 3,296,704 ADJUSTABLE GAUGING DEVICE Walter John Zajkowski, E. Park Road,
Hyde Park, NY. 12538 Filed Nov. 3, 1964, Ser. No. 403,485 1 Claim. (Cl. 33-458) This invention relates to gauging devices, and particularly to an improved adjustable mounting means for detachable blades therefor having gauging surfaces thereon adapted to contact a work piece being gauged.
An object of the invention is to provide a gauging blade mounting means whereby the blade may be quickly and easily adjusted to any desired position and, thereafter, held securely at the adjusted position.
Another object of the invention is to provide a blade mounting means whereby the blade is arranged exteriorly of the gauge frame proper.
Other objects and features of the invention will be evident when the following description is considered in connection with the appended drawing wherein the invention is shown embodied in a typical form of a go, no go snap or limit gauge having two parallel adjustable anvils arranged on the lower arm thereof. However, it will be understood that the invention can be embodied in other forms of adjustable gauges well known to persons familiar with the gauging art. Accordingly, the illustrated embodiment is not to be construed as defining or limiting the scope or application of the invention, the claim appended to this specification being relied upon for that purpose.
In the drawing:
FIGURE 1 is an isometric view of a side elevation looking from the bottom of a limit gauge to which the gauging blade mounting means according to this invention has been applied;
FIGURE 2 is an isometric view looking from the top and rear of a gauging blade per se; and
FIGURE 3 is an isometric view looking from the top and front of the same blade.
Referring to FIG. 1, the frame of the illustrated gauging device is comprised of upper and lower arms 11 and 12, respectively, arranged substantially parallel and adjustably secured at their rearmost portion to risers 13 and 14 whereby the distance between the arms may be varied to accommodate the entry therebetween of various sizes of workpieces.
The gauging blades 15, 16 and 17 are arranged at the foremost portion of the arms exteriorly of the frame proper and the specific mounting means there-for, which is the subject of this invention, will be described in detail below.
The outer end face 18 of arm 11 and the outer end face 19 of arm 12 are finished as true fiat surfaces (by grinding or any other usual machine shop practice for making true flat surfaces) in a common plane normal to the longitudinal axes of the arms. Two or more pins 20 are set in the face 18 and a tapped bore is formed therein to accommodate holding screw 21, the pins and bore being normal to the fiat surface 18. These pins and the holding screw serve to afiix the upper gauging blade 15, which has a flat surface 22 ground thereon, to the outermost end of arm 11. Thus, the upper blade 15 carrying edge 23 is held secure and the edge 23 serves as a fixed gauging surface adapted to contact a work piece to be gauged.
The end face 19 of the lower arm 12 is bored and tapped normal thereto to accommodate holding screws 24 and 25 which form one part of the securement means for the lower adjustable gauging blades 16 and 17, respectively. The outermost sections of the sides 12a and 12b of the foremost portion of the arm 12 are ground fiat Patented Jan. 10, 1967 "ice in parallel planes normal to the end face 19 of the arm. Each of these ground flats on the sides of arm 12 are bored and tapped normal thereto to accommodate a holding screw 26 (only the one entering into the face 12a being shown in the drawing) which forms a second part of the securement means for the lower adjustable gauging blades 16 and 17, respectively.
Each of the lower gauging blades 16 and 17 are L- shaped in sectional outline an identical as to the mounting means arrangement, and the rear and front configuration thereof is clearly shown in FIGS. 2 and 3, respectively. The inner faces (17a and 17b for example) of each lower blade are ground fiat in planes normal to each other. The sides of the L- shaped blades 16 and 17 are provided with slots 27 and 28 as shown to accommodate the passage of holding screws 26, and 25 or 24, respectively. One side of each of the L- shaped blades 16 and 17 is extended in the axial direction of the slots and the edges (30 and 29, respectively,) formed thereon serves as the other or adjustable gangingsurface adapted to contact a work piece to be gauged. In the embodiment shown, the L- shaped blades 16 and 17 are preferably adjusted and secured to the arm 12 so that their gauging surfaces 30 and 29 are at a different overall dimension from the fixed gauging surface 23 in order to provide a gauge of the go, no go type.
The under surface of the foremost portion of the lower frame arm 12 is bored and tapped near its outermost end to accommodate holding screws 31, the heads of which overlap the bottoms of the sides of the L- shaped blades 16 and 17 as shown and form a third part of the securement means for the lower adjustable gauging blades.
In the assembly of the lower or L-shaped gauging blades (blade 17 for example) to the gauge frame, the ground flats 17 b and 17a on the inside of the blade to be mounted on the gauge frame are placed adjacent the ground fiat 19 on the outer end face of arm 12 and the ground flat on the outermost section 12a of the arm 12, respectively, and holding screw 26 is screwed down through its coacting slot 27 to the extent that there is a tight sliding fit between surface 17a of the blade and surface 12a of the arm. Next, holding screw 24 is screwed down through its coacting slot 28 to the extent that there is an equivalent tight sliding fit between surfaces 17 b and 19. At this time, the lineal distance to be gauged is set between the gauging surfaces 23 and 29 with a master gauge, a final vernier adjustment to the set dimension be ing obtained by turning down holding screw 31, the head of which overlaps in the manner described above the bottom of the sides of the L-shaped blade. When the exact setting has been accomplished, the holding screws 24 and 26 may be turned down tightly and the blade is thus secured.
Gauging blade 16 is mounted with a similar procedure and the lineal distance between its gauging surface 30 and the fixed surface 23 similarly set by means of a master gauge.
From the above, it may be seen that the gauging blades are quickly and easily adjusted, quickly and easily mounted, secured in three planes at any desired dimension, and that the blades are arranged exteriorly of the gauge frame proper thereby increasing the utility of the gauge.
It is pointed out as a specific feature of the invention that all of the machining necessary to provide the true fiat surfaces comprised in the blade mounting means according to this invention is performed on an open surface either on the outside faces of the gauge frame arms or on the inside faces of the L-shaped blade pieces, and that no grooves, indentations or other specifically shaped guide surfacesvare required. Hencethe .cost ofproduction is substantially reduced.
I claim:

(a) a true fiat surface defined on the outer end face of each of the arms,
