Abstract
Abstract One of a pair of laterally spaced ball projecting wheels is adjustable laterally with respect to the other for accommodating the projecting of balls of different diameters, and a ball feed chute associated with the wheels is formed in lateral segments one of which is movable laterally with the laterally adjustable wheel for varying the width of the feed chute to correspond with the spacing between the wheels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
A ball projecting device, comprising: (a) a base member, (b) a pair of ball projecting members having confronting ball-engaging surfaces spaced apart laterally for gripping a ball between them, at least one of said members being driven for moving its ball-engaging surface in a ball projecting direction, (c) mounting means interengaging the base member and ball projecting members for lateral adjustment of at least one of said members relative to the other for varying the spacing between said confronting surfaces, (d) a ball feed chute including a pair of laterally disposed separate segments, and (e) coupling means connecting said lateral segments each with a different one of said ball projecting members for varying the width of the feed chute simultaneously with varying the spacing between said confronting surfaces.
Claim 2
Dependent Claim
128 words
A ball projecting device, comprising: (a) a base member, (b) a pair of ball projecting members having confronting ball-engaging surfaces spaced apart laterally for gripping a ball between them, at least one of said members being driven for moving its ball-engaging surface in a ball projecting direction, (c) mounting means interengaging the base member and ball projecting members for lateral adjustment of at least one of said members relative to the other for varying the spacing between said confronting surfaces, (d) a ball feed chute including a pair of laterally disposed separate segments, and (e) coupling means connecting said lateral segments each with a different one of said ball projecting members for varying the width of the feed chute simultaneously with varying the spacing between said confronting surfaces.
Claim 3
Dependent Claim
43 words
The ball projecting device of claim 1 wherein the coupling means connecting one of the lateral segments of the feed chute with its associated ball projecting member includes adjustment means for moving the lateral segment laterally relative to its associated ball projecting member.
Claim 4
Dependent Claim
64 words
The ball projecting device of claim 1 wherein the mounting means comprises attaching means for securing one of said ball projecting members on the base member against lateral displacement, and adjusting means for securing the other of said ball projecting members on the base member for lateral adjustment relative to the said one ball projecting member for varying the spacing between said confronting surfaces.
Claim 5
Dependent Claim
50 words
The ball projecting device of claim 3 wherein the coupling means comprises securing means for securing one of the lateral segments on the base member against lateral displacement, and connector means interconnecting the other of said lateral segments and the said other ball projecting member for simultaneous lateral adjustment thereof.
Claim 6
Dependent Claim
29 words
The ball projecting device of claim 4 wherein the connector means includes adjustment means for moving the said other lateral segment laterally relative to its associated ball projecting member.
