Abstract
Abstract This invention is a locator pin. It has a mounting end portion and an integral head end portion, wherein the head end portion of the locator pin is a cylindrical form with oblong cross section the ends of the cross section being arcuate. The sides can be straight or curved. A machine for forming the head end portion of the pin has a base rigidly mountable. A housing is transversely movably mounted on the base. A pin mounting is on the housing. The machine in use rotates the pin mount simultaneously with moving the housing transversely on the base, so the head end portion of the pin can be ground to have a cylindrical form oblong in cross section with the ends of the cross section being arcuate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A locator pin, comprising: a. a mounting end portion having means to rigidly mount said pin in a socket of a supporting structure; b. a head end portion integral with said mounting portion, and c. said head end portion being of a cylindrical form oblong in cross section with the ends of the cross section being arcuate, said head end portion extending from said supporting structure when said pin is mounted and having means To removably receive and temporarily mount an aperture of a workpiece, said locator pin in use is constructed and adapted to have said mounting end portion rigidly mounted in a tooling jig or the like with said head end portion extending from said tooling jig to removably receive and temporarily mount a workpiece, or the like.
Claim 2
Dependent Claim
130 words
A locator pin, comprising: a. a mounting end portion having means to rigidly mount said pin in a socket of a supporting structure; b. a head end portion integral with said mounting portion, and c. said head end portion being of a cylindrical form oblong in cross section with the ends of the cross section being arcuate, said head end portion extending from said supporting structure when said pin is mounted and having means To removably receive and temporarily mount an aperture of a workpiece, said locator pin in use is constructed and adapted to have said mounting end portion rigidly mounted in a tooling jig or the like with said head end portion extending from said tooling jig to removably receive and temporarily mount a workpiece, or the like.
Claim 3
Dependent Claim
18 words
The locator pin of claim 1, wherein said head end portion has an essentially elliptical transverse cross section.
Claim 4
Dependent Claim
32 words
The locator pin of claim 2, wherein: a. said head end portion and said mounting end portion are generally aligned, and b. said head end portion has a champhered free end portion.
Claim 5
Dependent Claim
60 words
The locator pin of claim 3, wherein; a. a flange portion extends from said locator pin at the juncture of said head end portion and said mounting end portion, and b. said head end portion has a circular portion adjacent to said flange portion, having a diameter approximately equal to the minor axis diameter of said elliptical transverse cross section.
Claim 6
Dependent Claim
34 words
The locator pin of claim 4, wherein: a. said locator pin is elongated, b. said mounting end portion has an essentially circular cross section, and c. said champhered end portion is champhered generally circularly.
Claim 7
Dependent Claim
148 words
In a tooling jig or the like for mounting a workpiece or the like, and having a rigidly mounted principal locator pin and at least one other rigidly mounted locator pin both mounted in a pin support, that improvement of the latter pin thereof, having: a. a mounting end portion mounting same in said pin support, and b. a head end portion integral with said mounting end portion, said head end portion being of a cylindrical form oblong in cross section with the ends of the cross section being arcuate, said head end portion extending from said pin support and having means to receive and temporarily mount a workpiece through an aperture therein, said pins and said pin support constructed and adapted to receive and temporarily mount a workpiece or the like through apertures therein or to receive and mount a part of a machine or the like.
Claim 8
Dependent Claim
148 words
In a tooling jig or the like for mounting a workpiece or the like, and having a rigidly mounted principal locator pin and at least one other rigidly mounted locator pin both mounted in a pin support, that improvement of the latter pin thereof, having: a. a mounting end portion mounting same in said pin support, and b. a head end portion integral with said mounting end portion, said head end portion being of a cylindrical form oblong in cross section with the ends of the cross section being arcuate, said head end portion extending from said pin support and having means to receive and temporarily mount a workpiece through an aperture therein, said pins and said pin support constructed and adapted to receive and temporarily mount a workpiece or the like through apertures therein or to receive and mount a part of a machine or the like.
Claim 9
Dependent Claim
89 words
The combination of claim 6, wherein: a. said principal locator pin is constructed and adapted to restrain said workpiece in both transverse and longitudinal directions; b. said second-named locator pin is constructed and adapted to restrain said workpiece in the transverse direction, c. said head end portion is essentially elliptical in transverse cross section, and d. said second-named locator pin is mounted with said tooling jig or the like in a position having the major axis portion of said generally elliptical cross section generally aligned with the transverse direction.
Claim 10
Dependent Claim
54 words
The combination of claim 7, wherein: a. a flange portion extends from said second-named locator pin at the juncture of said head end portion and said mounting end portion, b. said head end portion and said mounting end portion are generally aligned, and c. said head end portion has a champhered free end portion.
