adapted for use in connection with molds employed or used in the manufacture of glassware. One of the objects of the present invention is to provide a device of this character which will venable the operator at predetermined intervals during the blowing operation to open and close.

the mold sec tions with facility.

A still further important object of the invention is to provide a structure of this character which enables the operator to have free use of his hands for the blowing operation and to control the opening and closing ofthe mold sections by means of the feet.

A still further important object of the invention will be found to reside in the novel frame supporting structure andthe arrangement of the mold and operating levers therefor permitting of the efficient operation of the workman therewith.

The present invention contemplates the provision of a suitable platformen which the work- ,man may stand and on which there isarranged in a novel manner the mold especially constructed for the molding of thin glassware in one piece. On the platform are arranged suitable actuating levers for opening and Vclosing the sectional mold sections of the stem mold, vand for opening and closing the blow-heads of the body mold, said operating levers being arranged on the platform. at a convenient position with respect tothe operator for elicientworkmanship.

v and embodiment of the invention, the reference numeral 6 generally designates the supporting table which includesatop 8 having secured on the underneath side thereof adjacent the rear and front edges transversely disposed angle irons I0. f From the underneath side of the the angle ir served these top 8 and secured to ons I0 are legs I2. Aswill be oblegs I2 are constructed of angle iron 1937, serial No. r133,243

and have secured in spaced relation from the lower ends thereof transversely extending angle iron supports I6. Upon the supports I6 are arranged the angle iron members I8. As will be observed, these members project outwardly from the front portion and have secured transversely thereof to the free end a cross member of angle iron construction 22. At the intersections of the legs and the members I8 there is further secured another angle iron cross member 26 forming a support for the mold platform 28. Upon this mold platform therey is secured a mold support and mold structure of the type fully disclosed and described in my pending application. Briefly, this includes as illustrated a pair of spaced

pedestals

30 and 32 which are secured to the platform 28 and rise therefrom on the upper end of which by means of bolts 34 there is secured a plate 36 which has a central opening therein. A shell 38 of cylindrical shape rises around concentrically of the opening in the plate in which there is rotatably mounted the body mold. Above the shell 38 the rotatably mounted body mold 31 has on opposite diametrically disposed sides pivotally mounted thereto the sections 48 and 42 forming the head. As clearly illustrated the sections are provided with laterally extending arms 46 for a purpose to be more fully hereinafter described.

'Ihe stem mold-is formed of semi-cylindrical half-

sections

48 and 49 each section having an apertured ear 50 respectively turning on a common pivot 52 which is secured to the support 28.y

Extending transversely of the member I8 and secured thereto is a rod 68 having secured cenutrally thereon spaced

collars

64 and 66. These collars as clearly illustrated are secured in position on the rod `by means of the set screws 66 and have arranged in the upper portion thereof transversely extending slots in which there are secured upstanding leaf spring members 68 which are secured within the slots by means of the screw bolts T0. The members 68 are provided in their upper free ends with spaced eyes I2 separated by means of a longitudinally extending slot 14. The

spring members

64 and 66 are connected to `the

lugs

54 and 56 of the sectional stem mold sections by means of the links 14. As will be observed the links are downturned at one end and are received in the apertures in the lugs and at the other end are provided with eyes which are received in the slot 14 and secured therein by means of a bolt extending through the eyes I2 and the eyes in the links. To the rod 60 adjacent one end thereof there is secured another collar by means of a set screw 82 and having in the slotted end thereof a horizontally extending spring leaf member of similar construction 84. It will be observed that this spring member 84 extends horizontally and forwardly and has pivotally mounted at the free end thereof the free end of an operating rod 86. 'I'his rod extends upwardly through an aperture in the table and isprovided on its upper end thereof with a head 88. The sectional mold sections are normally maintained in their open position by means of the spring 90 which has one end secured to an extended portion of one of the levers 14 and the other endto the rear transversely extending angleriron member |6. It will thus be seen, that in the open position of the mold sectons the operating lever or rod 86 is in its upwardly extendedv position the bowl section being adapted to be closed upon a depressing ofthe head 88. llt is to be noted further that the

leaf springs

64, 66 and 84 permit of an abrupt and positive closing of the bowl sections and a snap action opening of the same upon the release of foot pressure from the operating head 88.

It will be observed that the head sections 40 and 42 are normally maintained in their` closed position by their respective weights. The head sections are adapted to be opened and permitted to close by meansvof gravity throughthe operating mechanism which includes a semi-circular shaped cross head 96 having secured thereto by means of screw bolts depending pins 98 which pins are adapted to engage the laterally extending arms 46 of the head sections. Adjacent the free ends of thecross member 96 there are secured upwardly extending arms and |02. These arms extend upwardly throughA apertures in the platform or top 8 and on the arm |02 there is secured a head |04. Between the head |04 and the top of the table 8 there is provided a spring |06 encircling the arm |02 normally maintaining the member 96 in an uppermost position and holding thepins 98 out of engagement with the arms 46 of the head sections permitting the head sections to assume their normally closed position by means of gravity. Upon a depressing of the head |04 the pins 98 contact the arms 46 opening the head sections. In thecentral portion of the front end of the table 8 there is provided an inwardlydirected V-shaped slot ||0. This slot as will be observed', is. directly above the U-shaped cross head member and permits of access from the front end and top of the table to the head of the mold.

In operation, the head sections are normally maintained in their closed postion by gravity, the operator standing on top of the table 8 closing the sections of the'sectional stem mold by depressing the head 88. The operator after obtaining a suliicient quantity of molten glass'on the free end of his blow pipe inserts the same through the mold head into the mold and after completing the molding operation raises one foot from the head 88 effecting an Vautomatic opening of the mold sections forming the stem of the ware, and upon a depressing of the head |04 by the other foot opens the mold head permitting, of the completed blown ware tobe removed from the mold. rIt will be observed, that the workman or operators hands are entirely free for the blowing operation, the control of the mold during the molding operation being effected by the feet of the operator.
