Abstract
Abstract Positioning of a scoop is synchronized with operation of an automatic machine to catch parts while a minimum amount of chips are falling. The scoop is pivotally attached to the end of a chute that comprises telescoping troughs. A pneumatic actuator is attached to the troughs, and control means synchronized with the machine operates the actuator for extending the troughs. The scoop has an arm for engaging a stationary stop as the troughs are nearly retracted for throwing the part along the troughs to a tote tray.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A machine attachment for catching parts comprising: an extensible chute adapted to be attached to an automatic machine with a cutoff tool, one end of said chute being a catching portion with an open top for catching falling parts, said chute normally being retracted outside the path to be taken by falling parts and chips, an extensible actuator connected between the opposite ends of said extensible chute, control means connected to said actuator and adapted to be mounted on said automatic machine, a control operator adapted to be connected to said automatic machine to move in synchronism with the operation of said cutoff tool and to engage said control means, said control means operating in response to engagement by said control operator to extend said extensible actuator and said chute for positioning said catching portion beneath said cutoff tool for an instant at the end of each of the cutoff operations of said machine for catching a part to be conveyed Along said chute, and said control means reoperating at the end of each of said cutoff operations to retract said extensible chute.
Claim 2
Dependent Claim
183 words
A machine attachment for catching parts comprising: an extensible chute adapted to be attached to an automatic machine with a cutoff tool, one end of said chute being a catching portion with an open top for catching falling parts, said chute normally being retracted outside the path to be taken by falling parts and chips, an extensible actuator connected between the opposite ends of said extensible chute, control means connected to said actuator and adapted to be mounted on said automatic machine, a control operator adapted to be connected to said automatic machine to move in synchronism with the operation of said cutoff tool and to engage said control means, said control means operating in response to engagement by said control operator to extend said extensible actuator and said chute for positioning said catching portion beneath said cutoff tool for an instant at the end of each of the cutoff operations of said machine for catching a part to be conveyed Along said chute, and said control means reoperating at the end of each of said cutoff operations to retract said extensible chute.
Claim 3
Dependent Claim
140 words
A machine attachment for catching parts as claimed in claim 1 wherein said one end of said chute having a catching portion is a scoop fastened to the remainder of said chute by a pivot on a transverse axis permitting said chute to be rotated upwardly about the upper portion of the remainder of the chute to which it is attached, a projecting member for tilting said scoop about said pivot, said projecting member extending outwardly from a point below said pivot, a stop positioned in line with the path of travel of said projecting member to be engaged thereby as said extensible chute approaches its normal retracted position, and said scoop in response to engagement of its projecting member by said stop being rotated upwardly about said pivot to discharge any part therein to said remainder of said chute.
Claim 4
Dependent Claim
43 words
A machine attachment as claimed in claim 2 wherein said remainder of said chute comprises first and second troughs, said second trough being a longitudinal sliding fit within said first trough, said scoop being pivoted to the extensible end of said second trough.
Claim 5
Dependent Claim
39 words
A machine attachment as claimed in claim 3 wherein said extensible actuator is a double-acting fluid cylinder having its cylinder fixed with respect to said first trough and its piston connected to said extensible end of said second trough.
Claim 6
Dependent Claim
42 words
A machine attachment for catching parts as claimed in claim 4 wherein said first trough has a longitudinal slot along the bottom thereof as a keyway, and a key member extending downwardly from the bottom of said second trough through said keyway.
