Abstract
Abstract For feeding billets into a forging press in either an upstanding or recumbent attitude, a selective loading mechanism is mounted between the exit end of a chute and an infeed mechanism thereunder. The selective loading mechanism comprises a vertical loader assembly including a tubular guide for permitting the passage therethrough of each billet onto the infeed mechanism, and a horizontal loader assembly including a pair of pivotable gripping jaws for loading each billet on the infeed mechanism after turning the billet through an angle of 90 degrees. The vertical and the horizontal loader assemblies are mounted on a carriage for selective movement to and away from their working position. The infeed mechanism comprises a vertical billet carrier for receiving and carrying the successive billets vertically, and a horizontal billet carrier for receiving and carrying the billets horizontally. The vertical and the horizontal billet carriers are to be interchangeably attached to a cylinder-driven, wheeled carriage, thereby to be transported into the forging press.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
Apparatus for feeding articles to a desired destination in either of two different attitudes, comprising: (a) chute means for conveying successive articles therethrough, the chute means having an exit end; (b) infeed means for transporting the articles from a loading position to the desired destination; and (c) selective loading means comprising: (1) first loading means for loading each article coming out of the exit end of the chute means onto the infeed means in a first upstanding attitude; (2) second loading means for loading each article coming out of the exit end of the chute means onto the infeed means in a second recumbent attitude by changing its orientation; and (3) changeover means for selectively moving the first and second loading means to and from a working position between the chute means and the infeed means.
Claim 2
Dependent Claim
136 words
Apparatus for feeding articles to a desired destination in either of two different attitudes, comprising: (a) chute means for conveying successive articles therethrough, the chute means having an exit end; (b) infeed means for transporting the articles from a loading position to the desired destination; and (c) selective loading means comprising: (1) first loading means for loading each article coming out of the exit end of the chute means onto the infeed means in a first upstanding attitude; (2) second loading means for loading each article coming out of the exit end of the chute means onto the infeed means in a second recumbent attitude by changing its orientation; and (3) changeover means for selectively moving the first and second loading means to and from a working position between the chute means and the infeed means.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1, wherein the first loading means comprises a hollow guide for permitting each article to pass therethrough from the chute means to the infeed means.
Claim 4
Dependent Claim
115 words
The apparatus of claim 1, wherein the second loading means comprises: (a) a stop for arresting the motion of each article that has come out of the exit end of the chute means; (b) means for releasably holding the article on the stop; (c) means for angularly displacing the releasably holding means between a first position, where the article that has come out of the exit end of the chute means is stopped by the stop, and a second position where the article is loaded on the infeed means; and (d) control means for causing the releasably holding means to hold the article only during the angular displacement from the first to the second position.
Claim 5
Dependent Claim
29 words
The apparatus of claim 3, wherein the releasably holding means comprises a pair of gripping jaws movable toward and away from each other to engage and disengage the article.
Claim 6
Dependent Claim
77 words
The apparatus of claim 4, wherein the control means comprises: (a) resilient means biasing the pair of gripping jaws toward each other; (b) first abutment means for causing the gripping jaws to be held apart from each other against the bias of the resilient means in the first position; and (c) second abutment means for causing the gripping jaws to be held apart from each other against the bias of the resilient means in the second position.
Claim 7
Dependent Claim
63 words
The apparatus of claim 3, wherein the working receiving position of the second loading means is displaced a predetermined distance from the working receiving position of the first loading means, and wherein the apparatus further comprises means for moving at least the exit end of the chute means between the two working receiving positions so that the chute means feeds the appropriate position.
Claim 8
Dependent Claim
38 words
The apparatus of claim 1, wherein the infeed means comprises: (a) a carriage; (b) carrier means on the carriage for carrying the successive articles in the first or the second attitude; and (c) means for moving the carriage.
Claim 9
Dependent Claim
52 words
The apparatus of claim 7, wherein the carrier means comprises: (a) first carrier means for carrying the articles in the first attitude; and (b) second carrier means for carrying the articles in the second attitude; (c) the first and the second carrier means being adapted to be interchangeably attached to the carriage.
