Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
75 words
A shot peening apparatus comprising support means for holding the object to be peened, a bank of a multiple of centrifugal shot throwing wheels supported on a common mounting member above said support means for projecting the peening shot against the object to be peened, a free moving centrifugal shot throwing wheel disposed above said support means, and feed means for supplying peening shot to said bank of wheels and to said free moving wheel.
Claim 2
Dependent Claim
75 words
A shot peening apparatus comprising support means for holding the object to be peened, a bank of a multiple of centrifugal shot throwing wheels supported on a common mounting member above said support means for projecting the peening shot against the object to be peened, a free moving centrifugal shot throwing wheel disposed above said support means, and feed means for supplying peening shot to said bank of wheels and to said free moving wheel.
Claim 3
Dependent Claim
23 words
An apparatus as set forth in claim 1 wherein said free moving wheel is universally mounted and is mounted for back-and-forth oscillatory movement.
Claim 4
Dependent Claim
36 words
An apparatus as set forth in claim 2 wherein said bank of wheels includes a set of wheels on one side of said mounting member and another set on the other side of said mounting member.
Claim 5
Dependent Claim
19 words
An apparatus as set forth in claim 3 wherein said bank of wheels are staggered in a zig-zag manner.
Claim 6
Dependent Claim
20 words
An apparatus as set forth in claim 4 including means for rotating said bank of wheels at least about 90*.
Claim 7
Dependent Claim
59 words
An apparatus as set forth in claim 5 wherein said mounting member is compartmentalized into a plurality of compartments corresponding to the number of wheels in said bank and each of said compartments is arcuate over an arc extending at least 90*, and said compartments communicating with said feed means throughout the rotational movement of said bank of wheels.
Claim 8
Dependent Claim
23 words
An apparatus as set forth in claim 5 wherein said bank of wheels is mounted for vertical movement and for back-and-forth oscillatory movement.
Claim 9
Dependent Claim
31 words
An apparatus as set forth in claim 7 wherein said support means comprises a movable work car which moves longitudinally transverse to the back-and-forth oscillatory movement of said bank of wheels.
Claim 10
Dependent Claim
32 words
AN apparatus as set forth in claim 8 wherein synchronizing means are connected to said work car and to said bank of wheels for synchronizing said longitudinal movement with said osciallatory movement.
Claim 11
Dependent Claim
20 words
An apparatus as set forth in claim 8 including a pair of masking means disposed with a dihedral break therebetween.
Claim 12
Dependent Claim
18 words
An apparatus as set forth in claim 5 including digital control means connected to said bank of wheels.
Claim 13
Dependent Claim
42 words
An apparatus as set forth in claim 11 wherein said digital control means controls the vertical movement of said bank of wheels and controls the rotational speed of the wheels in said bank and controls the flow of shot to individual wheels.
Claim 14
Dependent Claim
36 words
An apparatus as set forth in claim 8 including electronic fail-safe means for stopping the flow of shot to the wheels when one of said work car and of said oscillating bank inadvertently stops its movement.
