Abstract
Abstract The blade guide invention relates to devices employed in bread slicing machines to guide band blades. Mounting to increase cutting accuracy and providing for increased life and reduced tendency to seize the band blades is achieved by a blade guide (11) with body, guide and attachment portions (16, 17, 18) formed in a unitary construction. The guide portion includes spaced apart prongs (19, 21, 22) with improved wear surfaces (24, 31a, 31b) forming a channel (36a) for the band blade.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
A blade guide for use in bread slicing machines employing band blades, said guide comprising: body means for attachment to a slicing machine; and means for guiding band blades, including first and second guide structures extending from said body means and forming a guide channel therebetween, said first guide structure including at least one first guide prong, said second guide structure including at least two second guide prongs, said first and second guide prongs having wear surfaces which face each other across said guide channel, said second guide prongs being spaced apart to form a slot communicating with said guide channel, said first guide prong being disposed such that said slot is across said guide channel from said first guide prong's wear surface, the band blade being received in said guide channel.
Claim 2
Dependent Claim
132 words
A blade guide for use in bread slicing machines employing band blades, said guide comprising: body means for attachment to a slicing machine; and means for guiding band blades, including first and second guide structures extending from said body means and forming a guide channel therebetween, said first guide structure including at least one first guide prong, said second guide structure including at least two second guide prongs, said first and second guide prongs having wear surfaces which face each other across said guide channel, said second guide prongs being spaced apart to form a slot communicating with said guide channel, said first guide prong being disposed such that said slot is across said guide channel from said first guide prong's wear surface, the band blade being received in said guide channel.
Claim 3
Dependent Claim
141 words
A blade guide for use in bread slicing machines employing band blades, said guide comprising: body means for attachment to a slicing machine; and means for guiding band blades, including first and second guide structures extending from said body means and forming a guide channel therebetween, said first guide structure including at least one first guide prong, said second guide structure including at least two second guide prongs, said first and second guide prongs having wear surfaces which face each other across said guide channel, said first guide prong has longitudinal surface defining spaces disposed to each side of said first guide prong, said spaces communicating with said guide channel, said second guide prongs being disposed such that said spaces are across said guide channel from said second guide prong's wear surfaces, the band blade being received in said guide channel.
Claim 4
Dependent Claim
141 words
A blade guide for use in bread slicing machines employing band blades, said guide comprising: body means for attachment to a slicing machine; and means for guiding band blades, including first and second guide structures extending from said body means and forming a guide channel therebetween, said first guide structure including at least one first guide prong, said second guide structure including at least two second guide prongs, said first and second guide prongs having wear surfaces which face each other across said guide channel, said first guide prong has longitudinal surface defining spaces disposed to each side of said first guide prong, said spaces communicating with said guide channel, said second guide prongs being disposed such that said spaces are across said guide channel from said second guide prong's wear surfaces, the band blade being received in said guide channel.
Claim 5
Dependent Claim
20 words
The blade guide of claim 1 or 2 and further wherein said wear surfaces are formed of a metal carbide.
Claim 6
Dependent Claim
20 words
The blade guide of claim 1 or 2 and further wherein said wear surfaces are formed of a metal boride.
Claim 7
Dependent Claim
34 words
The blade guide of claim 1 or 2 and further wherein said first and second guide prongs have surfaces directed away from said guide channel, said surfaces having a plurality of fins joined thereto.
Claim 8
Dependent Claim
24 words
The blade guide of claim 1 or 2 and further wherein said body means and means for guiding band blades form a unitary construction.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
75 words
A blade guide for use in bread slicing machines employing band blades, said guide comprising: unitary means having body means for attachment to a slicing machine and means for guiding band blades contiguous with said body means; said means for guiding having a plurality of prongs and a guide channel disposed between said prongs, no prong being directly facing another prong across said guide channel, wear surfaces of hardened material being formed on said prongs.
Claim 11
Dependent Claim
13 words
