Abstract

The disclosure relates to a contour transfer device which may be used to transfer contours such as those found on the bodies of automobiles so that a proper contour from one side may be transferred to an opposite side of the vehicle which has been damaged.

The disclosure relating specifically to a pair of bars clamped together and with a row of finger receiving openings in which feeler and contour transfer fingers are slideably mounted laterally relative to the bars and wherein the bars are provided with frusto-conical openings in their adjacent sides in which O-rings are nested and frictionally engaged around the fingers and wherein clamp bolts clamp the bars together to compressively force the O-rings into frictional engagement with the feeler and contour transfer fingers so that the fingers may be held in a desired adjusted position.

Claims

1. A contour transfer device comprising first and second elongated main bars;

said bars disposed in adjacent parallel relation to each other;

each of said bars having a facing side and an outer side;

said facing side being adjacent to each other;

each of said main bars having a plurality of finger receiving holes extending laterally through each of said bars and said holes in each bar disposed in a substantially straight row;

the finger receiving holes of said first bar being axially aligned with said holes in said second bar;

elongated feeler and contour transfer fingers extending through said aligned finger receiving holes of both of said bars;

each bar, in its facing side, having a frusto-conical recess surrounding each of said finger receiving holes therein;

said frusto-conical recess diverging toward said facing side;

resilient O-rings disposed in said frusto-conical recesses;

each of said rings closely surrounding one of said feeler and contour transfer fingers;

the cross sectional diameter of each O-ring being sufficient to engage and nest in said frusto-conical recesses and to compressively hold said main bars in slightly spaced apart relation to each other at facing sides;

each of said fingers having a peripheral portion; and

clamp bolts disposed adjustably to force said main bars together to thereby reduce the spacing between said facing sides of said bars and to thereby compress said resilient O-rings in said Frusto-conical recesses and to thereby cause compressive frictional engagement of each O-ring about the said peripheral portions of a respective one of said feeler and contour transfer fingers whereby said fingers, when longitudinally adjusted in a direction laterally of said bars, will hold an adjusted position with substantial resistence to change.

2. The invention as defined in claim 1, wherein:

each of said bars has a generally rectangular cross sectional shape and is provided with opposite edge portions disposed at substantially right angles to said facing sides and said outer sides of said bars.

3. The invention as defined in claim 2, wherein:

said edge portions being substantially spaced from said finger receiving holes.

4. The invention as defined in claim 3, wherein:

said bars are provided with bolt receiving openings therein;

said bolt receiving openings being disposed substantially parallel to said finger receiving openings.

5. The invention as defined in claim 4, wherein:

said bolt receiving openings being located between said finger receiving openings and one of said edge portions.

6. The invention as defined in claim 5, wherein:

said bolt receiving openings in one of said bars being bolt clearance holes;

said bolt receiving openings in the other of said bars being internally screw threaded and adapted to screwthreadably receive said clamp bolts.
