Abstract

Abstract A dressing tool includes a rotatable cutting means with an elongated probe member coaxially disposed therein. The probe member extends outwardly beyond the cutting means. The alimentary canal is cleaned by drawing a vacuum through the elongated probe which is to be inserted into the anus of the poultry. The anus is then drawn away from the body of the poultry by drawing a vacuum in the space between the probe and the cutting means. Another feature of this invention is directed to the use of a control mechanism to provide the necessary sequence of operations so that the dressing tool will operate automatically under assembly line conditions.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 82 words
A dressing tool for poultry and the like comprising: a. a rotatable cutting means, b. an elongated, hollow probe means coaxially disposed within said rotatable cutting means and extending outwardly beyond the cutting means, c. first means for drawing a vacuum through the elongated probe means, d. second means for drawing a vacuum in the space between the probe means and the rotatable cutting means, and e. means for rotating said cutting means while said second vacuum drawing means is being operated.
Claim 2
Dependent Claim 82 words
A dressing tool for poultry and the like comprising: a. a rotatable cutting means, b. an elongated, hollow probe means coaxially disposed within said rotatable cutting means and extending outwardly beyond the cutting means, c. first means for drawing a vacuum through the elongated probe means, d. second means for drawing a vacuum in the space between the probe means and the rotatable cutting means, and e. means for rotating said cutting means while said second vacuum drawing means is being operated.
Claim 3
Dependent Claim 27 words
A dressing tool as defined in claim 1 wherein said rotatable cutting means includes a cylindrically shaped cutting knife adapted to be rotated by said rotating means.
Claim 4
Dependent Claim 41 words
A dressing tool as defined in claim 1 wherein said rotatable cutting means includes a cylindrically shaped cutting member, and said elongated, hollow probe means is fixedly mounted within said said cutting member so that the cutting member will rotate therearound.
Claim 5
Dependent Claim 39 words
A dressing tool as defined in claim 1 wherein control means are operatively connected to said rotatable cutting means and said first and second vacuum drawing means to provide automatic sequential operation thereof upon actuation of said dressing tool.
Claim 6
Dependent Claim 69 words
A dressing tool as defined in claim 4 wherein said first vacuum drawing means includes a line extending from a vacuum source to the hollow probe means, said control means includes a valve means located in said vacuum line and a AND logic circuit and a timing logic circuit, said timing logic circuit being connected to the output of the AND circuit and the input of the valve means.
Claim 7
Dependent Claim 43 words
A dressing tool as defined in claim 4 wherein said control means includes means for sequentially activating the first vacuum drawing means, said second vacuum drawing means and said rotating means in their sequential order to effectuate the evisceration of a poultry carcass.
Claim 8
Independent Claim 91 words
A system for dressing poultry and the like comprising: a. at least one dressing tool having a rotatable cutting means and an elongated probe means coaxially disposed within said rotatable cutting means, b. a cutting vacuum chamber being defined by the space between the probe means and the rotatable cutting means, c. means for connecting said dressing tool to a compressed air source and a vacuum source, and d. control means for drawing a vacuum on the cutting vacuum chamber at the same time that the cutting means is being rotated.
Claim 9
Independent Claim 91 words
A system for dressing poultry and the like comprising: a. at least one dressing tool having a rotatable cutting means and an elongated probe means coaxially disposed within said rotatable cutting means, b. a cutting vacuum chamber being defined by the space between the probe means and the rotatable cutting means, c. means for connecting said dressing tool to a compressed air source and a vacuum source, and d. control means for drawing a vacuum on the cutting vacuum chamber at the same time that the cutting means is being rotated.
Claim 10
Dependent Claim 47 words
A system as defined in claim 7 wherein said control means includes a vacuum valve for connecting the cutting vacuum chamber to the vacuum source, a NOT logic circuit to control said vacuum valve and an actuating means for energizing said NOT circuit at a desired time.
Claim 11
Dependent Claim 128 words
A system as defined in claim 7 wherein said rotating means includes an air driven motor operatively connected to said rotatable cutting means, said control means includes a normally closed air vAlve disposed between a compressed air source and the air driven motor, and means for opening said closed air valve to operate said cutting means, said valve opening means including an AND logic circuit, timing circuit means connected to the output of said AND logic circuit, and an air valve actuatable by drawing a vacuum thereon being connected to the input of said AND logic circuit, said AND logic circuit being additionally connected to a supply air line whereby an output signal is generated to said timing circuit when a vacuum is drawn on said air valve.
