Abstract
A combination square is provided with a square head that includes a pair of bores extending through a blade receiving slot, a pair of pins, each pin having an eccentric outermost surface and being engaged in a corresponding one of the bores, and a ruled blade that is releasably engaged in the slot such that the relative angle between the head and the blade can be adjusted by rotating one or both of the pins about the axis of the corresponding bore.
Claims21
A combination square comprising:
- a head having a planar head surface to abut a workpiece, a blade receiving slot having an end opening in the planar head surface, and a pair of spaced bores, with each bore centered on a corresponding bore axis and a portion of each bore extending through the blade receiving slot;
- a pair of spiral roll pins, each of the pins engaged in a corresponding one of the bores with a portion of the pin extending through the blade receiving slot and portions of the pin engaged in portions of the corresponding one of the bores on opposite sides of the blade receiving slot, each pin having a rotational position about the corresponding bore axis;
- and
- a ruled blade releasably received in the blade receiving slot and having a planar blade surface that extends from the end opening in the first planar head surface;
- and
- wherein a relative angle between the planar head surface and the planar blade surface is determined by the rotational position of each of the pins.
A combination square comprising:
- a head having a planar head surface to abut a workpiece, a blade receiving slot having an end opening in the planar head surface, and a bore centered on a bore axis with a portion of the bore extending through the blade receiving slot;
- a spiral roll pin engaged in the bore with a portion of the pin extending through the blade receiving slot and portions of the pin engaged in portions of the bore on opposite sides of the blade receiving slot;
- and
- a ruled blade releasably received in the blade receiving slot and having a planar blade surface that extends from the end opening in the first planar head surface;
- and
- wherein a relative angle between the planar head surface and the planar blade surface can be adjusted by rotating the pin about the bore axis.
A method of squaring a combination square comprising a ruled blade and a head, the head having a blade receiving slot and a bore centered on a bore axis with a portion of the bore extending through the blade receiving slot, the method comprising the steps of:
- inserting the blade into a releasably retained position in the blade receiving slot of the head;
- and
- adjusting a relative angle between the head and the blade by rotating a spiral roll pin retained in the bore about the bore axis with a portion of the pin extending through the slot until the blade is squared with the head.
A combination square comprising:
- a head having a planar head surface to abut a workpiece, a blade receiving slot having an end opening in the planar head surface, and a bore centered on a bore axis with a portion of the bore extending through the blade receiving slot;
- a pin engaged in the bore with a portion of the pin extending through the blade receiving slot and portions of the pin engaged in portions of the bore on opposite sides of the blade receiving slot, the pin having an eccentric outermost surface;
- and
- a ruled blade releasably received in the blade receiving slot and having a planar blade surface that extends from the end opening in the first planar head surface;
- and wherein a relative angle between the planar head surface and the planar blade surface can be adjusted by rotating the eccentric outermost surface of the pin about the bore axis.
