Magazine-equipped slug-driving tool

Claim 2

In a slug-driving tool a. a support having a forward end, b. a bucking comb carried by said support for receiving work having a capacity into which a slug is to be driven, c. an elongated magazine on said support containing a plurality of slugs in alignment, d. a nosepiece mounted on the forward end of said support and including an open ended slug chamber in alignment with said magazine, said chamber presenting a forward wall, e. means included as a part of said magazine to bias the slugs therein towards said nosepiece whereby the foremost slug is held against said forward wall, f. a plunger carrier mounted on said support and movable towards and away therefrom, g. a plunger mounted in said carrier and, h. means to align the work supported by said bucking comb with said plunger.

Claim 3

A slug-driving tool as defined in claim 1 wherein said work-aligning means comprises at least one forward projection on the forward end of the magazine.

Claim 4

A slug-driving tool as defined in claim 1 wherein an operating handle is pivoted to said support and a second operating handle is provided in pivot relationship to said plunger carrier, and a pivot is provided between said handles.

Claim 5

A slug-driving tool as defined in claim 1 wherein said plunger carrier has a rectilinear movement toward and away from the work support and is power operated.

Claim 6

A slug-driving tool as defined in claim 3 wherein said magazine extends generally lengthwise of the handles and therebetween and has its forward end mounted on said support in fixed relationship thereto with the rear end of the magazine free.

Claim 7

A slug-driving tool as defined in claim 3 wherein said magazine extends generally lengthwise of the handles and therebetween and has its forward end mounted on said support in fixed relationship thereto with the rear end of the magazine free, the magazine comprising a C-shaped channel member receiVing slugs therein and further comprising a compression spring on the channel member for support thereby, the spring at its forward end reacting against a spring yoke in embracing relation to the spring and pivoted to a spring follower within the channel member, said spring yoke having latching means to latch over the rear end of the magazine upon compression of the spring to hold the follower in the retracted position thereof when loading the magazine through its forward end, said nosepiece being movably mounted for loading of the magazine through the forward end thereof.

Claim 8

A slug-driving tool as defined in claim 3 wherein the nosepiece comprises a slidable generally tubular part spring biased to the aforementioned position thereof in which it forms a part of said slug chamber and being movable to a retracted position against said bias in which it may be rotated to be latched in an out-of-the-way position for loading of the magazine through the front end thereof.

Claim 9

A slug-driving tool as defined in claim 3 wherein a motion-compelling mechanism is provided for said operating handles comprising a channel member fixed to one handle having a pawl located intermediate of the walls of the channel and pivoted therein, said motion-compelling mechanism also comprising a toothed bladelike ratchet member extending into the channel member for cooperation with the pawl, the ratchet member being pivoted intermediate of its ends by said pivot between the handles and pivoted at its other end by means of an adjustable eccentric to a locking arm, said locking arm being mounted on the other of said operating handles, whereby adjustment of the eccentric functions to vary the extent of travel of the slug-driving plunger.

Claim 10

A slug-driving tool as defined in claim 3 wherein said magazine extends generally lengthwise of the handles and therebetween has its forward end mounted on said support in fixed relationship thereto with the rear end of the magazine free, the nosepiece being a slidable generally tubular part spring biased to the aforementioned position thereof in which it forms a part of said slug chamber and being movable to a retracted position against said bias in which it may be rotated to be latched in an out-of-the-way position for loading of the magazine through the front end thereof.

Claim 11

A slug-driving tool as defined in claim 3 wherein said magazine extends generally lengthwise of the handles and therebetween and has its forward end mounted on said support in fixed relationship thereto with the rear end of the magazine free, and wherein a motion-compelling mechanism is provided for said operating handles comprising a channel member fixed to one handle having a pawl located intermediate of the walls of the channel and pivoted therein, said motion-compelling mechanism also comprising a toothed bladelike ratchet member extending into the channel member for cooperation with the pawl, the ratchet member being pivoted intermediate of its ends by said pivot between the handles and pivoted at its other end by means of an adjustable eccentric to a locking arm, said locking arm being mounted on the other of said operating handles, whereby adjustment of the eccentric functions to vary the extent of travel of the slug-driving plunger.

Claim 12

A slug-driving tool as defined in claim 3 wherein said nosepiece comprises a slidable generally tubular part spring biased to the aforementioned position thereof in which it forms a part of said slug chamber and being movable to a retracted position against said bias in which it may be rotated to be latched in an out-of-the-way position for loading of the magazine through the front end thereof.

Claim 13

A slug-driving tool as defined in claim 4, wherein the plunger carrier has mounted thereto a plurality of slug-driving plungers, each operating through a nose section of the magazine to cooperate with one slug therein, to drive the cooperating slugs simultaneously.

Claim 14

A slug-driving tool as defined in claim 12, wherein the plunger carrier is Operated by a valved fluid cylinder forming a tool handle and provided with a piston rod secured to the carrier for effecting reciprocating movements of the latter.

Claim 15

A slug-driving tool as defined in claim 13 wherein the plunger carrier is of yoke-shape, embracing the magazine, the magazine being detachable and separable from the tool.

Claim 16

A slug-driving tool as defined in claim 13 wherein the feed mechanism for the slugs includes a pusher part within the magazine rearwardly of the slugs and an opening in a wall of the magazine through which a spring follower extends engaging said pusher part and urging it forwardly.

Claim 17

A slug-driving tool as defined in claim 13 wherein the plunger carrier is of yoke-shape, embracing the magazine, the magazine being detachable and separable from the tool and wherein the feed mechanism for the slugs includes a pusher part within the magazine rearwardly of the slugs and an opening in a wall of the magazine through which a spring follower extends engaging said pusher part and urging it forwardly.
