Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A lock mechanism for supporting and locking equipment on a vibratory mill, comprising two non-circular pins rigidly fixed to the equipment having mutually coincident axes; receiving means for receiving said non-circular pins, said receiving means including two rigid brackets having U-shaped channels cut therethrough and resilient receiving elements lining said channels into which said non-circular pins can be positioned; and said non circular pins each having a minor cross-sectional dimension which fits within each resilient receiving element and a major cross-sectional dimension which is wider than said U-shaped channel with said resilient receiving element in position, said non-circular pins and said resilient receiving elements being capable of interlocking engagement by placement of said non-circular pins in said U-shaped channels and by rotation of the equipment relative to said vibratory mill about an axis coincident with the axes of the non-circular pins, said non-circular pins being forced along the major cross-sectional dimension thereof into interlocking engagement with said resilient receiving elements.
Claim 2
Dependent Claim
160 words
A lock mechanism for supporting and locking equipment on a vibratory mill, comprising two non-circular pins rigidly fixed to the equipment having mutually coincident axes; receiving means for receiving said non-circular pins, said receiving means including two rigid brackets having U-shaped channels cut therethrough and resilient receiving elements lining said channels into which said non-circular pins can be positioned; and said non circular pins each having a minor cross-sectional dimension which fits within each resilient receiving element and a major cross-sectional dimension which is wider than said U-shaped channel with said resilient receiving element in position, said non-circular pins and said resilient receiving elements being capable of interlocking engagement by placement of said non-circular pins in said U-shaped channels and by rotation of the equipment relative to said vibratory mill about an axis coincident with the axes of the non-circular pins, said non-circular pins being forced along the major cross-sectional dimension thereof into interlocking engagement with said resilient receiving elements.
Claim 3
Dependent Claim
12 words
The device of claim 1 wherein said pins are of oval cross-section.
Claim 4
Dependent Claim
12 words
The device of claim 1 wherein said non-circular pins have coincident axes.
Claim 5
Dependent Claim
18 words
The device of claim 1 wherein said receiving means includes two rigid brackets having U-shaped channels cut therethrough.
Claim 6
Dependent Claim
18 words
The device of claim 4 wherein said resilient receiving elements line the U-shaped channels of said rigid brackets.
Claim 7
Dependent Claim
22 words
The device of claim 1 wherein said non-circular pins just fit within said receiving means along a minor diameter of said pins.
Claim 8
Dependent Claim
46 words
The device of claim 1 wherein said non-circular pins are angled with respect to the final position of the equipment so that said pins may be positioned without interference in said receiving means with the equipment oriented at around a 15* angle from its in-place orientation.
Claim 9
Dependent Claim
15 words
The device of claim 1 wherein said resiliently lined channel includes lining material of polyurethane.
Claim 10
Dependent Claim
25 words
The device of claim 1 wherein said pins physically interlock with said resiliently lined channels when the equipment is finally positioned on the vibratory mill.
