Abstract
Abstract By providing in a carcass saw an easily accessible switch and associated blade-reversing means, serious jamming of the saw-blade and related jumping of the blade out of its guides in the saw are avoided and a return to normal saw operation in minimal time and with minimal damage is assured.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
An improved carcass saw, including: a frame; first and second rims spaced from each other and each rotatably supported from said frame; a common saw blade carried by both of said rims; adjusting means for adjusting the spring between said rims for tensioning said common saw blade; motor means coupled to one of said rims for causing such rim to rotate in a first direction, whereby said saw blade is caused to move in a first direction; and, reversing means coupled to said motor means for reversing the direction of rotation of said motor means, whereby said saw blade is caused to move in the opposite direction.
Claim 2
Dependent Claim
107 words
An improved carcass saw, including: a frame; first and second rims spaced from each other and each rotatably supported from said frame; a common saw blade carried by both of said rims; adjusting means for adjusting the spring between said rims for tensioning said common saw blade; motor means coupled to one of said rims for causing such rim to rotate in a first direction, whereby said saw blade is caused to move in a first direction; and, reversing means coupled to said motor means for reversing the direction of rotation of said motor means, whereby said saw blade is caused to move in the opposite direction.
Claim 3
Dependent Claim
14 words
Apparatus according to claim 1 in which said motor means is an electrical motor.
Claim 4
Dependent Claim
68 words
Apparatus according to claim 1 including, in addition, a pair of guide blocks supported from said frame adjacent respective ones of said rims for orienting said blade; first cover means supported from said frame and covering said first rim, second cover means supported from said frame and covering said second rim; and, first and second troughs rotatably supported from said frame beneath said first and second rims, respectively.
Claim 5
Dependent Claim

Claim 8
Dependent Claim
17 words
Apparatus according to claim 4 in which said slurry exhaust means comprises, in each case, a hose.
Claim 9
Dependent Claim
36 words
Apparatus according to claim 3 which includes, in addition, spraying means positioned proximate to said blade and operative to cause spraying liquid to impinge upon said blade whereby said blade is cleaned and slurry is formed.
Claim 10
Dependent Claim
24 words
Apparatus according to claim 3 in which each of said troughs has a slot therein for the passage and guidance of said saw blade.
Claim 11
