Abstract
Abstract A fluid power driven roof nailing machine which receives a roofing nail and a sealing disc and, keeping them axially aligned, drives the nail through the disc into a surface to be nailed. The machine includes an arm swingably driven by a fluid motor, a sealing disc holder fixedly carried by the free end of the arm, and a nail driver positioned at the free end of the arm and mounted for sliding movement relative to the disc holder. A method of attaching roofing using such a machine is also disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
A nailing machine comprising: a wheeled carriage adapted for movement on a surface to be nailed, a frame mounted on said carriage, force transmitting means including a stroking member, means mounting said force transmitting means on said frame for movement of said stroking member through a nailing stroke, a nail driver, and means interconnecting said stroking member and said nail driver and including lost motion means operative to allow inertial movement of said nail driver from a rest position adjacent said stroking member to a working position remote from said stroking member in response to movement of said stroking member through its nailing stroke.
Claim 2
Dependent Claim
104 words
A nailing machine comprising: a wheeled carriage adapted for movement on a surface to be nailed, a frame mounted on said carriage, force transmitting means including a stroking member, means mounting said force transmitting means on said frame for movement of said stroking member through a nailing stroke, a nail driver, and means interconnecting said stroking member and said nail driver and including lost motion means operative to allow inertial movement of said nail driver from a rest position adjacent said stroking member to a working position remote from said stroking member in response to movement of said stroking member through its nailing stroke.
Claim 3
Dependent Claim
83 words
A nail driving machine as defined in claim 1 and further including: means on said to releasably retain a nail on the leading surface of the driver, and means for releasably retaining a sealing disc in a position forward of the positioned nail and in the path of inertial movement of said driver so that the nailing stroke operates to deposit the sealing disc on the nailing surface and, instantaneously thereafter, drive the nail through the sealing disc and into the nailing surface.
Claim 4
Dependent Claim
27 words
A nail driving machine as defined in claim 1 and further including means on said to releasably retain a nail on the leading surface of the driver.
Claim 5
Dependent Claim
102 words
The nailing machine is defined in claim 1 wherein said stroking member comprises: an arm pivotally mounted adjacent one end on said frame for movement between a rest position in which the free end of said arm is remote from said nailing surface, and a working position in which said free end is adjacent to said nailing surface, and said force transmitting means includes: a source of motive power mounted on said frame, including means converting said power to rotary mechanical power, and operatively connected to pivot said arm, and said nail driver is carried adjacent the free end of said arm.
Claim 6
Dependent Claim
39 words
The nailing machine as defined in claim 4 wherein said source of motive power comprises: a source of pressurized fluid; a reversible fluid motor in fluid communication with said source of pressurized fluid and operatively connected to said arm.
Claim 7
Dependent Claim
47 words
A nailing machine as defined in claim 5 and further comprising: means for stopping the movement of said arm at said rest position; and means for preventing movement of said arm away from said rest position until a predetermined differential pressure across said motor has been reached.
Claim 8
Dependent Claim
79 words
The nailing machine as defined in claim 4 wherein said lost motion means comprises: a plurality of rods extending perpendicularly from the longitudinal side of said arm confronting said nailing surface when said arm is in the working position; bores formed through said nail driver and registering with said rods to allow sliding movement of said nail driver on said rods; and means disposed on said rods for stopping movement of said nail driver at its remote working position.
Claim 9
Dependent Claim
47 words
A nail driving machine as defined in claim 7 wherein said stopping means comprises: a sealing disc holding member fixedly connected to the free ends of said rods and having formed therethrough a centrally located aperture spaced radially inwardly from said through bores in said nail driver.
Claim 10
Dependent Claim
30 words
A nailing machine as defined in claim 8 wherein said disc holding member is generally ring shaped and includes a magnetic surface at the face thereof remote from said arm.
Claim 11
Dependent Claim
27 words
A nailing machine as defined in claim 9, wherein said driver comprises a hammer member including a magnetic surface at the end thereof remote from said arm.
Claim 12
Dependent Claim
31 words
A nailing machine as defined in claim 8 wherein said disc holding member is generally ring shaped and includes a replaceable adhesive surface at the face thereof remote from said arm.
Claim 13
Dependent Claim
28 words
A nailing machine as defined in claim 8 wherein said nail driver comprises a hammer member including a magnetic surface at the end thereof remote from said arm.
Claim 14
Dependent Claim
28 words
A nailing machine as defined in claim 8 wherein said driver comprises a hammer member including a replaceable adhesive surface at the end thereof remote from said arm.
Claim 15
Dependent Claim
48 words
A nailing machine comprising: a wheeled carriage adapted for movement over a surface to be nailed, a frame mounted on said carriage, a reciprocally rotatively actuated arm pivotally mounted on said frame, and nail driving means carried on the free end of said arm and reciprocally rotatable therewith.
Claim 16
Dependent Claim
48 words
A nailing machine comprising: a wheeled carriage adapted for movement over a surface to be nailed, a frame mounted on said carriage, a reciprocally rotatively actuated arm pivotally mounted on said frame, and nail driving means carried on the free end of said arm and reciprocally rotatable therewith.
