Hand-held setting tool and method for setting deformable head fasteners

Claim 2

A hand-held tool adaptable for setting a plurality of types of headed fasteners each of which is set by pulling the fastener to deform the head comprising (a) a housing including an anvil; (b) a cavity in the housing; (c) first and second reciprocatable non-rotatable puller means for selective mounting in the cavity; each puller means capable of pulling at least one type of fastener; (d) a first handle fixed to the housing; (e) a second handle slidably engageable with each puller means and pivotably mounted on the housing to move each puller means reciprocally in the housing over a fixed range by manipulation of the handles toward and away from one another; (f) the first puller means having an internal bore throughout the length of the puller means and a mandrel holder threadedly engageable in the bore of such puller means so that the mandrel holder is movable axially further in and axially further out of the puller means; such mandrel holder having a lower threaded stem portion extending from the cavity of the housing for threaded engagement with the fastener; and (g) the second puller means adapted to be substituted in the housing cavity for the first puller means; said second puller means having jaw means to releasably grip an unthreaded fastener stem.

Claim 3

A hand-held tool adapted for setting a plurality of fasteners each set by pulling a fastener stem to deform the head comprising (a) a housing including an anvil; (b) a cavity in the housing; (c) a plurality reciprocatable non-rotatable puller means for mounting in the cavity each puller means capable of pulling at least one type of fastener; (d) a first handle fixed to the housing; (e) a second handle slidably engageable with the puller means and pivotably mounted on the housing to move the puller means reciprocally in the housing over a fixed range by manipulation of the handles toward and away from one another; (f) a first puller means having an internal bore throughout the length of the puller means; and (g) a mandrel holder threadedly engageable in the bore of such puller means so that the mandrel holder is movable axially further in and axially further out of the puller means; such mandrel holder having a lower threaded stem portion extending from the cavity of the housing for threaded engagement with the stem of a fastener; whereby the distance between the anvil and the rivet nut may be varied by (1) inserting and securing in the tool mandrels of selected length and (2) adjusting the mandrel holder axially in the puller means to in turn vary the position of the rivet nut carrying mandrel with respect to the anvil.

Claim 4

A hand-held tool adapted for setting a plurality of fasteners each set by pulling a fastener stem to deform the head comprising (a) a housing including an anvil; (b) a cavity in the housing; (c) a plurality reciprocatable non-rotatable puller means for mounting in the cavity each puller means capable of pulling at least one type of fastener; (d) a first handle fixed to the housing; (e) a second handle slidably engageable with the puller means and pivotably mounted on the housing to move the puller means reciprocally in the housing over a fixed range by manipulation of the handles toward and away from one another; (f) a first puller means having an internal bore throughout the length of the puller means; and (g) a mandrel holder threadedly engageable in the bore of such puller means so that the mandrel holder is movable axially further in and axially further out of the puller means; such mandrel holder having a lower threaded stem portion extending from the cavity of the housing for threaded engagement with the stem of a fastener; whereby the distance between the anvil and the rivet nut may be varied by (1) inserting and securing in the tool mandrels of selected length and (2) adjusting the mandrel holder axially in the puller means to in turn vary the position of the rivet nut carrying mandrel with respect to the anvil.

Claim 5

The tool of claim 2 in which the puller means and the mandrel holder are engaged through left hand threads such that counterclockwise rotation of the mandrel holder causes it to move axially further into the puller means and in which the upper stem portion of the mandrel and the mandrel holder are engaged with right hand threads.

Claim 6

The tool of claim 2 in which the puller means and the mandrel holder are engaged through right hand threads such that clockwise rotation of the mandrel holder causes it to move axially further into the puller means and in which the upper stem portion of the mandrel and the mandrel holder are engaged with right hand threads.

Claim 7

The tool of claim 2 in which the mandrel holder is threadedly adjustable toward the housing to bring the handles closer together so that during the setting stroke the reciprocating movement of the puller means is less than its full range.

Claim 8

The tool of claim 2 in which the anvil is integrally formed in the housing.

Claim 9

The tool of claim 2 in which the anvil is detachable from the housing.

Claim 10

The tool of claim 2 in which the anvil is a ring means slidably mounted on the mandrel in a position so that the ring means is urged against the housing during setting of the rivet nut.

Claim 11

The tool of claim 2 in which the lower threaded stem portion of the mandrel including thread means for receiving and holding the stem of a rivet bolt.

Claim 12

The tool of claim 2 in which a plurality of mandrels are used having different lengths and differing lower stem diameters to accommodate differing sizes and types of head-deformable fasteners.
