Abstract
Abstract A machine for portioning out nails, screws or like articles of magnetically attractable material from a supply of such articles to an outlet where the articles are packaged, has conveyors and a weighing machine cooperating with them for rapid portioning out of definite article portions minus a small number of articles which at the end of the rapid portioning operation are portioned out individually by the weighing machine for supplementing said definite portion, a magnet chute for orienting articles falling through the chute from the weighing machine or from a conveyor cooperating with said weighing machine, and a packaging unit for packaging the article portions in cartons or boxes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
A machine for portioning out definite portions of nails, screws and like articles from a supply of such articles to an outlet of said machine, comprising supply means, weighing means, receiving means including a magnetizable chute, for receiving, orienting and bringing together the articles in a portion to a compact set suitable for packaging and for advancing said set to the outlet of the machine for subsequent packaging, and feed means for feeding saId articles from said supply means to said weighing and from said weighing means to said receiving means, wherein said feed means includes a high-speed feeder means for rapid feed of articles and a fine feeder means for individual feed of the articles at the point of feed of said articles and said weighing means includes an electronic weighing machine connected to said high-speed feeder means and said fine feeder means and adapted to stop the high-speed feeder means immediately before the feed of the definite portion weight adjusted so as to permit said fine feeder means to feed further articles individually until the exactly adjusted portion weight has been reached and thereby stop said fine feeder means.
Claim 2
Dependent Claim
191 words
A machine for portioning out definite portions of nails, screws and like articles from a supply of such articles to an outlet of said machine, comprising supply means, weighing means, receiving means including a magnetizable chute, for receiving, orienting and bringing together the articles in a portion to a compact set suitable for packaging and for advancing said set to the outlet of the machine for subsequent packaging, and feed means for feeding saId articles from said supply means to said weighing and from said weighing means to said receiving means, wherein said feed means includes a high-speed feeder means for rapid feed of articles and a fine feeder means for individual feed of the articles at the point of feed of said articles and said weighing means includes an electronic weighing machine connected to said high-speed feeder means and said fine feeder means and adapted to stop the high-speed feeder means immediately before the feed of the definite portion weight adjusted so as to permit said fine feeder means to feed further articles individually until the exactly adjusted portion weight has been reached and thereby stop said fine feeder means.
Claim 3
Dependent Claim
41 words
A machine as claimed in claim 1, wherein said fine feeder means includes two relatively rotatable elements adapted during the rotary movement to advance articles in a space between them and to stop said advance when said rotary movement is stopped.
Claim 4
Dependent Claim
53 words
A machine as claimed in claim 2, wherein said relatively rotatable elements are two rods which are carried at an adjustable distance from one another and are adapted to support a row of articles in hanging position between said rods for advance and discharge of one nail at a time during the rotation.
Claim 5
Dependent Claim
114 words
A machine as claimed in claim 1, wherein said receiving means includes a swing arm cooperating said magnetizable chute for pressing the articles down against the bottom of said chute, and a motor-driven push member carried at one end portion of said chute for pushing together the articles in each article portion supplied to the chute from the weighing means when said arm is swung down into said chute for pressing down the articles, and for advancing the articles in said space to the other end of the chute, which other end constitutes said outlet, for delivery of each article portion in the form of a substantially compacted bunch for the subsequent packaging operation.
Claim 6
Dependent Claim
28 words
A machine as claimed in claim 4, including a motor for said swing arm operable by means of an operating mechanism located at the outlet of said machine.
Claim 7
Dependent Claim
59 words
A machine as claimed in claim 5, wherein said swing arm is adapted, when swung down into the chute, to actuate a means connected to said motor of said push member to cause said motor to advance said push member in said chute, and, when swung up from the chute, to actuate said motor to return said push member.
Claim 8
Dependent Claim
27 words
A machine as claimed in claim 4, wherein said swing arm is adapted to deliver an activating or deactivating impulse to a magnetizing apparatus for said chute.
Claim 9
Dependent Claim
36 words
A machine as claimed in claim 1, including control means for impulse transmission to a conveyor assembly and said weighing means in step with the packaging of article portions delivered at the outlet of said machine.
Claim 10
Dependent Claim
13 words
The machine as claimed in claim 1, wherein said weighing means is adjustable.
