Abstract
A blast head for a vacuum-blasting machine has a deflecting surface oriented at an angle to the direction in which particles under pressure are sent through the blast head. The blast head has an inner, blast jacket, an outer, vacuum jacket, and a blast head body connected to the vacuum jacket by a flexible bellows. The blast head body is secured to the blast jacket to permit axial movement of the blast jacket relative to the vacuum jacket.
Claims17
A blast head for a vacuum-blasting machine cleaning sides of elements projecting from larger surfaces, comprising:
- a vacuum jacket for engaging a surface from which an element projects, said vacuum jacket being connected to a vacuum source to conduct particles away from the surface;
- a blast jacket positioned within said vacuum jacket, said blast jacket having an open end for receiving the projecting elements;
- means for sending particles under pressure in predetermined directions through said blast jacket and into engagement with the projecting elements;
- and
- means for directing particles under pressure against sides of the projecting elements lying at angles relative to a plane transverse to the direction in which particles are sent through the blast jacket.
A blast head for a vacuum-blasting machine for cleaning sides of elements projecting from larger surfaces, comprising:
- a vacuum jacket for engaging a surface from which an element projects, said vacuum jacket being connected to a vacuum source to conduct particles away from the surface;
- a blast jacket positioned within said vacuum jacket, said blast jacket having an open end for receiving the projecting elements;
- means for sending particles under pressure in predetermined directions through said blast jacket and into engagement with the projecting elements;
- and
- means for directing particles under pressure against sides of the projecting elements lying at angles relative to a plane transverse to the direction in which particles are sent through the blast jacket,
- wherein said vacuum jacket defines a longitudinal axis, the blast head further comprising means for connecting said blast jacket to said vacuum jacket for movement relative to said vacuum jacket in a direction parallel to the longitudinal axis of said vacuum jacket.
In combination, an element projecting from a larger surface, said element having sides to be cleaned;
- and
- a blast head for a vacuum-blasting machine for cleaning said sides of the element, the blast-head comprising
- a vacuum jacket for engaging the surface from which said element projects, said vacuum jacket being connected to a vacuum source to conduct particles away from the surface;
- a blast jacket positioned within said vacuum jacket, said blast jacket having an open end for receiving the projecting elements;
- means for sending particles under pressure in a predetermined general direction through said blast jacket and into engagement with the projecting elements;
- and
- means for directing particles under pressure against said sides of said projecting element, said sides lying generally parallel to the predetermined general direction in which particles are sent through the blast jacket.
