Abstract
Abstract This application discloses a blast machine which includes a turret movable in a vertical plane and rotatable in a horizontal plane. Mounted inside the turret are throwing wheels which are supplied from a source of surface-treating material. The turret is mounted in a wall of a blast chamber so that when a workpiece to be treated is inside the chamber the turret may be moved vertically and rotated horizontally to insure treatment of the entire surface of the workpiece. The workpiece may be mounted on a carriage and moved to different positions within the chamber. The application also discloses an automatic control system so that the motions of the turret and the carriage may be controlled by a program stored on a data storage medium.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
Surface-treating apparatus comprising: a treating chamber; means for transporting a workpiece having a surface to be treated into and within said chamber; means for moving said workpiecetransporting means; at least one wall of said chamber having an opening therein; a turret mounted in said opening and having a dimension less than the dimension of said opening and having a central axis movable vertically within said opening to the limits of said opening dimension; at least one throwing wheel mounted in said turret for propelling surface treatment material against the surface of a workpiece; means for supplying surface treatment material to said throwing wheel; means for moving said turret to the limits of said opening dimension; and means for rotating said turret about said central axis within said opening.
Claim 2
Dependent Claim
128 words
Surface-treating apparatus comprising: a treating chamber; means for transporting a workpiece having a surface to be treated into and within said chamber; means for moving said workpiecetransporting means; at least one wall of said chamber having an opening therein; a turret mounted in said opening and having a dimension less than the dimension of said opening and having a central axis movable vertically within said opening to the limits of said opening dimension; at least one throwing wheel mounted in said turret for propelling surface treatment material against the surface of a workpiece; means for supplying surface treatment material to said throwing wheel; means for moving said turret to the limits of said opening dimension; and means for rotating said turret about said central axis within said opening.
Claim 3
Dependent Claim
34 words
The surface-treating apparatus of claim 1 wherein said turret has an opening into the interior of said chamber to provide access for material propelled by said throwing wheel to the surfaces of the workpiece.
Claim 4
Dependent Claim
59 words
The surface-treating apparatus of claim 1 including extensible and contractable sealing means connected to opposite ends of said turret so that upon movement of said turret within said opening said sealing means will extend and contract to maintain the portions of said opening not occupied bY said turret covered to prevent surface-treating material from coming out of said chamber.
Claim 5
Dependent Claim
51 words
The surface-treating apparatus of claim 3 wherein said sealing means comprises a pair of flexible curtains, each curtain having one end on a roller and the other end movable from said roller as to wind and unwind and cover and uncover exposed portions of said opening as said turret moves therein.
Claim 6
Dependent Claim
38 words
The surface-treating apparatus of claim 1 wherein said turret has rounded sides and an opening into the interior of said chamber and engaged opposite edges of said turret so that the turret opening faces entirely within said chamber.
Claim 7
Dependent Claim
83 words
The surface-treating apparatus of claim 1 wherein said turret has rounded sides and an opening into the interior of said chamber, extensible and contractual sealing means connected to opposite ends of said turret so that upon movement of said turret within said opening said sealing means will extend and contract to the positions of said opening not occupied by said turret covered to prevent surface-treating material from coming out of said chamber and to prevent the entry of undesired material into said chamber.
Claim 8
Dependent Claim
51 words
The surface-treating apparatus of claim 6 wherein said sealing means comprises a pair of flexible curtains, each curtain having one end on a roller and the other end movable from said roller as to wind and unwind and cover and uncover exposed portions of said opening as said turret moves therein.
Claim 9
Dependent Claim
128 words
The surface-treating apparatus of claim 1 in combination with means for controlling the movement and rotation of said turret within said opening and the movement of said workpiece-transporting means comprising: means for supplying input command signals representing the position desired for each motion of said turret and for said workpiece-transporting means deriving a signal representative of the actual positions of said turret and said workpiece-transporting means; means for comparing said input command signals and said actual position signals and producing difference signals; and means for producing motion command signals in response to said difference signals and supplying said signals to said turret-moving means, said means for rotating said turret and said means for moving said workpiece-transporting means to move said turret and said workpiece toward said desired positions.
Claim 10
Dependent Claim
103 words
The surface-treating apparatus of claim 1 including means for supplying surface-treating material to said throwing wheel; and expansible and contractual means interconnecting said supply means and said throwing wheel to provide a continuous supply of treating material to said throwing wheel as said turret moves and rotates in said opening. 10 The surface-treating apparatus of claim 1 wherein said means for moving said turret in said opening comprises a reversible motor mounted at the upper end, said opening and flexible means interconnecting said motor and said turret and said means for rotating said turret comprises a reversible motor connected to one end thereof.
Claim 11
Dependent Claim
14 words
The surface-treating apparatus of claim 10 including vertically movable counterweights connected to said turret.
Claim 12
Dependent Claim
130 words
The surface-treating apparatus of claim 10 in combination with means for controlling the movement and rotation of said turret within said opening and the movement of said workpiece-transporting means comprising: means for supplying input command signals representing the position desired for each motion of said turret and for said workpiece-transporting means deriving a signal representative of the actual positions of said turret and said workpiece-transporting means; means for comparing said input command signals and said actual position signals and producing difference signals; and means for producing motion command signals in response to said difference signals and supplying said signals to said housing turret means, said means for rotating said turret and said means for moving said workpiece-transporting means to move said turret and said workpiece-transporting means Toward said desired positions.
