Claim 4

In a machine for forming film articles comprising: a frame; a carriage; a form; means for rotationally mounting said form upon said carriage; a tank for holding a dipping solution; means attached to said carriage and said frame for lowering said carriage and said mounted form so said form is immersed in said dipping solution to coat said form; means attached to said frame and said carriage for raising said carriage so said coated form is removed from said dipping solution and; means attached to said frame for moving said form along said frame toward and away from said tank; the improvement comprising a means for rapidly securely engaging said form upon said machine and easily and rapidly removing said form from said machine, said means including a structure for connecting said form to said machine comprising a rod which fits into an opening formed in said carriage, said rod being secured in said carriage opening solely by an easily removable pin passing through a hole in said carriage, said hole being slightly larger than the size of the cross section of said pin, said pin further extending into a second hole in the side of said rod so that when said pin is removed, said rod can be easily pulled from said opening thus removing said form from said carriage.

Claim 5

The improvement in claim 2 wherein said structure further comprises at least one projection extending from said rod, said projection slipping easily into a slot formed in said carriage when said rod is inserted into said carriage opening.

Claim 6

In a machine for forming film articles comprising: a frame; a carriage; a form; means for rotationally mounting said form upon said carriage; a tank for holding a dipping solution; means attached to said frame and said carriage for lowering said carriage and said mounted form so said form is immersed in said dipping solution to coat said form; means attached to said frame and said carriage for raising said carriage so said coated form is removed from said dipping solution and; means attached to said frame for moving said form along said frame toward and away from said tank; the improvement comprising at least two racks mounted on said frame; at least two pinions each of said pinions having peripherally located teeth; and means for connecting said pinions to said form; at least one of said pinions having a toothless peripheral portion, the toothless portion on one of said pinions being proximate teeth on the other of said pinions; one of said pinions engaging one of said racks and the other of said pinions engaging the other of said racks, so that movement of said form along said frame causes said pinions and said form to rotate, and so that a gap in one of said racks will permit a pinion having a toothless peripheral portion engaged in the other of said racks to stop rotating at a predetermined position when the pinion engaged in said other rack rotates so that its toothless portion faces said other rack, and in that said machine is provided with a means for rapidly and securely engaging said form upon and easily and rapidly removing said form from said machine, said means having a structure for connecting said form to said machine said structure comprising a rod which fits into an opening formed in said carriage, said rod being held in said carriage opening by an easily removable pin passing through a hole in said carriage slightly larger than the cross section of said pin into a similar hole in the side of said rod.

Claim 7

In a machine for forming film articles comprising: a frame; a carriage; a form; means for rotationally mounting said form upon said carriage; a tank for holding a dipping solution; means attached to said frame and said carriage for lowering said carriage and said mounted form so said form is immersed in said dipping solution to coat said form; means attached to said frame and said carriage for raising said carriage so said coated form is removed from said dipping solution and; means attached to said frame for moving said form along said frame toward and away from said tank; the improvement comprising at least two racks mounted on said frame; at least two pinions each of said pinions having peripherally located teeth; and means for connecting said pinions to said form; at least one of said pinions having a toothless peripheral portion, the toothless portion on one of said pinions being proximate teeth on the other of said pinions; one of said pinions engaging one of said racks and the other of said pinions engaging the other of said racks, so that movement of said form along said frame causes said pinions and said form to rotate, and so that a gap in one of said racks will permit a pinion having a toothless peripheral portion engaged in the other of said racks to stop rotating at a predetermined position when the pinion engaged in said other rack rotates so that its toothless portion faces said other rack, and in that said machine is provided with a means for rapidly and securely engaging said form upon and easily and rapidly removing said form from said machine, said means having a structure for connecting said form to said machine said structure comprising a rod which fits into an opening formed in said carriage, said rod being held in said carriage opening by an easily removable pin passing through a hole in said carriage slightly larger than the cross section of said pin into a similar hole in the side of said rod.

Claim 8

In a machine for forming film articles comprising: a frame; a carriage; a plurality of forms; means for mounting said forms upon said carriage; a tank for holding a dipping solution; means attached to said frame and said carriage for lowering said carriage and said mounted forms so said forms are immersed in said dipping solution to coat said forms; means attached to said frame and said carriage for raising said carriage so said coated forms are removed from said dipping solution and; means attached to said forms for moving said forms along said frame toward and away from said tank; the improvement comprising means for individually rotating each of said forms upon said carriage, said means comprising a support attached to and extending from said carriage, a block attached to said support, a plurality of axles, one end of each of said axles being attached to one of said forms, each of said axles projecting through one of a plurality of holes in said block so each of said forms is able to rotate in relation to said block, at least one rotating device attached to the other end of each of said axles, a track and means for mounting said track to said frame, said mounting means being located between said frame and said forms, said rotating device being able to roll along said track causing said rod and said form to rotate.
