Patent number: 8317635Abstract: A set of iron-type golf clubs includes long, mid- and short irons with channel back configurations and a mass control insert. The mass of the insert is systematically varied through the set such that the mass distribution properties of the set may be systematically varied while retaining a continuous look and feel through the set. The mass of the insert is varied by altering the volume or the density of the insert through the set. Additional design parameters for the set may also be systematically varied through the set, such as groove type and depth, loft angle, cavity volume, hitting face roughness, and sole width. In one embodiment, the mass control insert comprises a dense insert and a lightweight cover. The density of the dense insert can be easily varied to change the mass distribution properties of the club head. One application of the mass control insert is to provide customization of the club head at the point of sale or distribution.Type: GrantFiled: March 22, 2011Date of Patent: November 27, 2012Assignee: Acushnet CompanyInventors: Peter J. Gilbert, Bruce R. Pettibone, Michael Scott Burnett, Christopher R. Kays, Tomas Diaz

Patent number: 7955189Abstract: The present invention is directed to a method of forming a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances. The grooves have sharp edges, radiused ends, and a draft angle between about 2° and 12°. The striking face is machined such that it has a uniform texture with a roughness of more than 40 Ra.Type: GrantFiled: February 1, 2010Date of Patent: June 7, 2011Assignee: Acushnet CompanyInventors: Robert W Vokey, Peter J Gilbert, M Scott Burnett, Christopher R Kays

Publication number: 20100144460Abstract: A set of iron-type golf clubs includes long irons with channel back configurations and short irons with cavity back configurations. The rear face configurations transition from channel backs through to pure cavity backs for increased performance continuum for the set. Additional design parameters for the set may also be systematically varied through the set, such as groove type and depth, loft angle, cavity volume, hitting face roughness, and sole width. At least one of the clubs of the set includes a sandwich-type construction for the hitting face having a dampening element disposed between a hitting face insert and a lightweight reinforcing core. In one embodiment, at least one club head is oversized.Type: ApplicationFiled: February 11, 2010Publication date: June 10, 2010Inventors: Peter J. Gilbert, Bruce R. Pettibone, Michael Scott Burnett, Christopher R. Kays, Tomas Diaz

Patent number: 7281991Abstract: A hollow golf club having a hosel sleeve weight made from tungsten material in the upper hosel area and a tungsten toe plug in the lower toe portion of the club head. This combination creates an increase in the moment of inertia of the club head about the x, y and z axes of the club head. A composite core is bladder molded into a cavity in the club head to provide support for a relatively thin front face and the composite core is visible on the rear surface of the club head. The core material is less dense and has greater flexibility than the front face.Type: GrantFiled: July 13, 2005Date of Patent: October 16, 2007Assignee: Acushnet CompanyInventors: Peter J.
