Opinion

JACKSON, Associate Judge.

This is an appeal from a decision of the Board of Appeals of. the United States Patent Office, affirming in all but two claims the decision of the Examiner which rejected claims 1 to 20, 22, 28 to 33, and 36. Claims 17 and 19 were allowed by the Board. Ten apparatus claims including 17 and 19, have been allowed.

During the oral argument here, appellant moved to dismiss the appeal with respect to claims 1 to 5, inclusive, 11, 13, 14, IS, 29, 30, 31, and 33, which motion will be granted.

Of the claims remaining for consideration, claims 7, 16, and 36 are illustrative, and read as follows:

“7. The method of forming a succession of hollow glass articles in a forming unit comprising a blank mold and a final blow mold cooperating solely with each other, which comprises successively and sequentially supplying a series of charges of plastic glass to the blank mold at the ends of uniform time intervals, successively and sequentially forming all the charges in the blank mold into parisons in uniform periods of time, supporting all the parisons so formed out of contact and out of registry with either the blank mold or the blow mold for reheating, successively and sequentially blowing all the reheated parisons to final form in the blow mold in uniform periods of .time, and so timing the various operations of the forming unit in the forming of a series of articles that at one time during each cycle of operation of the blank mold at least three charges of glass will be in the process of formation into glass articles, one having been supplied to the blank mold and being enclosed thereby, a second, which was previously formed into a parison in said blank mold reheating as aforesaid, and a third which was still earlier formed into *994 a parison in said blank mold being enclosed within said final blow mold.”

“16. Apparatus for forming hollow glass articles, comprising a blank mold adapted to be supplied with charges of plastic glass, a blow mold, means for forming a charge of glass supplied to said blank mold into a parison therein, means for removing a parison so formed from the blank mold and for suspending it for reheating out of contact and out of registry with any body mold surface and thereafter for moving the reheated parison to a position to be enclosed by the blow mold, means for blowing a reheated parison to final form in the blow mold, and means for timing the operations of all the aforesaid means in such manner that there is a time during each cycle of machine operation in which at least three charges of glass, all of which were supplied to said blank mold, are in the process of formation.”

“36. The method of forming a succession of hollow glass articles, which comprises supplying a series of charges of plastic glass to a blank mold which is in neck-down position, successively forming the charges in the blank mold into parisons, inverting the parisons so formed by the application of forces thereto to invert the parison while maintaining the center of inversion always between two planes both perpendicular to the longitudinal axis of the parison and passing respectively through the opposite ends thereof and thus bringing the parison to a neck-up position, supporting the parisons so formed out of contact and out of registry with any body mold surface for reheating, transferring the parisons to a final blow mold, blowing the reheated parisons to final form therein, and so timing the various operations on a series of charges of glass that at one time at least three charges of glass will be in the process of formation into glass articles: one having been supplied to the blank mold and being enclosed thereby, a second, which was previously formed into a parison in said blank mold, reheating as aforesaid, and a third, which was still earlier formed into a parison in said blank mold, being enclosed within a final blow mold.”

The claimed invention relates to a method and apparatus for forming glassware. It is described in the Examiner’s statement, omitting the numerals, as follows :

“The claimed invention relates to a method and apparatus for forming glassware. The apparatus comprises a base up- , on which is mounted a casting. The casting supports a blank mold and a blow mold. Each of these molds is made in two sections and means including pneumatic motors are provided for opening and closing these molds. Located centrally between these molds is a means for supporting two neck molds. These neck molds are supported and operated in the same manner, and each one at times cooperates with the blank mold to aid in the formation of the parison after which this neck mold is moved to a dwell position wherein the parison formed in the blank mold is permitted to reheat and air is blown into the parison, after which this neck mold is again moved in the same direction and transfers the parison to the blow mold where it is blown to final form. This neck mold is then returned for cooperation with the blank mold. The parison is formed in the blank mold in inverted or neck down position and during the movement of the parison from the blank mold to the dwell position, it is reverted to the neck up position. Both neck molds operate in the same manner and the operations of the machine are so timed that when one neck mold cooperates with the blank mold the other neck mold is at the dwell position with the parison previously formed in the blank mold while the blow mold holds the parison formed previous to the two mentioned above. This appellant designates as the ‘triple overlapping cycle.’ That is, three parisons are in the various stages of formation into a finished bottle on the machine at the same time, one being formed in the parison mold, another being at the dwell position where it is reheating and is being expanded and a third being in the blow mold where it is being shaped to final shape.

“In order to accomplish the transfer of the parisons from the blank mold to the blow mold in the manner stated without interference, the two neck molds move along different paths and they are for this purpose mounted upon an oscillating support. The support is oscillated by means of air motor connected thereto by means of arm and a shaft depending from the support. The> machine is also provided with the usual elements which cooperate with the molds in the formation of a bottle. These, for example, are the neck pin, settle blow head cooperating with the blank mold, blow head cooperating with the blow mold and the means for moving the neck molds to their various positions comprising motor operated rack bars. Means are also provided for opening and closing the neck molds at the *995 proper time. A blowing means is provided at each of the separate dwell positions of the two neck molds to expand the parison while reheating. The various elements are caused to operate at the proper time by the timing means.”
