Abstract
ABSTRACT
A Selector device for regular round barbell plates.
A metal fork shaped apparatus when inserted between the barbell plates support plates above so that the plates above will move, but the additional plates will remain stationary at floor level. This selector device can be distinguished from other inventions because this fork selector can be used with barbell plates more effieciently then any other invention previously known.

Description
SPECIFICATION
This invention relates to a manually operable weight-lifting exercise machine(s).
It is common in other exercise machines to use ~ectangular iron plates. These exercise machines cannot use the more conventional barbell plates.
The inventive idea which a selector device embodies, and the way which resort to it overcomes the difficulties and inconveniences of previous exercise machines.
I have found that the disadvantage may be over-come by using a selector device to separate barbell plates, which also allows for an almost friction free movement of the plates.
A full description of the best way of using or putting into operation the selector device. A drawing accom-pany's this description.
Example: A pulley and wire rope method.
The tool illustrated comprises (4), metal fork shaped appar-atus enters between (C) and (D), large plate discs. (3), centre prong on fork enters hole on (2), round metal tube of machine. When fork is secure prongs (6), (7), (8), and (3), support large plate discs above. (5), safety pin enters hole on (3), of fork. To select a different poundage of weight the pin is taken out of the fork. The fork is pulled out of machine and is moved up or down to the next selection of large plate discs. For example between discs (C) and (B),or (B) and (A),etc., the same procedure is used as with (D) and (C). (X), are lesser diameter barbell plates used to separate (D,) and (C), (C~ and (B), (B) and (A), etc.. (2), is attached to a wire rope which goes around a pulley. When the rope is pulled and released, the discs, with fork secured, sliae up and down (1), Round metal tube support guides, postioning larger bar bell plate discs, and smaller barbell plate discs, but allow-ing vertical movement on machine.
~, ~o~/2 '' : ,, ~1'7~
Other ways in which the inventive idea may be used or put into operation.
The selector device with regular round barbell plates in con~uction with machine specifically 1 and 2. A
leverage method is used. And also a nearly friction free vertical movement can be performed. As illustrated by the drawing with the rope and pulley method. Best results are with 5, 10,and 20 pound cement plastic type barbell discs with 2 pound cement plastic barbell discs to separate. And with 5, 10, and 20 pound iron barbell plates with 2~ or 5 pound iron barbell plates to separate. Larger or smaller weights are not adviseable because selection would be too great. Example: If the machine was stacked with 50 pound weights selection would be roughly every 100 pounds. The same disadvanta~e could be said for anything less than 5 pounds weights.

Claims (5)
1) A manually operable tool for separating various weights of regular barbell plates on a weight lifting exercise machine, comprising a selector fork, 2 support guides which position large and small barbell plates, and a tube which acts as a lifting mechanism, which when joined and attached with selector fork by insertion in any one of the holes in the tube and secured with safety pin selection is made, and ready to be lifted by an exercise of leverage or rope and pulley method.
2) A tool as defined in Claim 1 in which the selector fork is a bar or tube with 5 prongs rigidly secured thereto.
3) A tool as defined in Claim 1 or 2 in which the centre prong is used to join as defined in Claim 1 the selector fork to the lifting of machine.
4) A tool as defined in Claim 1 or 2 in which the other 4 prongs are used to support as defined in Claim 1 the larger barbell plates.
5) A tool as defined in Claim 1 a pin which enters a hole in centre prong of selector fork as defined in Claim 1 which when secure acts as a safety device disallowing the selector fork to retrack out of machine.
