Y rEEssING-rLUNGEE MEcHAnIsr/I FOR GLASS-MACHINES.
. of the United States, No. 1,326,365, granted to me on December 30th", 1919. More particularly my present invention comprises. new and improved means for.
mounting the pressing plunger in the ma c'hine whereby the plunger may be properly centered and alined in relation to the mold or molds into which the plunger is to enter.
Further my invention consists in a new and improved mounting of the spring ring which closes the mouth of the mold.
Many other'novel features of construction and arrangement of parts willappear from the followingdescription. I
In the accompanying drawings, which are merely intended to illustrate a practical embodiment of the principles of my invention without limiting the scope of the same to the construction shown, Figurel is a broken elevationof the pressing mechanism of a machine embodying my invention; Fig. 2 is an enlarged vertical section of the same, the.
pressing plunger being shown in dotted lines and Fig. 3 is a horizontal section taken. along the line IIIIII in'Fig. 2.
The following is a'detailed description of the drawings. p
A and B represent a pair of standards which form part of the general machine, not shown, or other suitable vertical supports.
C represents a member, such as a cross head, slidably mounted on said standards,
To indicate in a general way the application of power to move the cross head C up and down on the standards A and B, I show toggle links 1, but it will be understood that any suitable application of power may be used. I 1
The cross head 0 is provided with a transverse, horizontal opening 2, and 3 is a central circular hole extending through the top Specification of Letters Patent.

of the cross head into shaft extending resting on the bottom of the opening 2. The shaft 4 is threaded, and 5 is a nutscrewed the-opening 2. 4 is a down through the hole 3 and. o
on said shaft up against the top of the openof the bolts 9 are threaded and screwed into threaded holes 12 in the mold closing ring D. I
The holes 12 are tangentially intersected by small horizontal holes 13, in which are screwed the screw bolts 14 thereby locking the bolts 9 from unscrewing from the ring D. 15 represents helical springs coiled about the upper ends of the bolts 9 and bearing against the bar 6 while their greater portions are contained in relatively deep coun- Y 'tersinks inthe sleeves 10.
It is evident that the springs 15 tend to de- 16 is a horizontal yoke having a central hole whichloosely fits the shaft 4: and its position on said shaft withinthe opening 2 is determined by the nut 17 screwed on' the shaft below the yoke. The upper face of the nut 17 is rounded so that the yoke may rock in" a vertical plane. i
18 represents a pair of gripping fingers whose upper ends are pivotally secured to the slotted or bifurcated ends of the yoke 16 and whose lower ends depend through slots 19 in the cross head C. and are provided below said cross head ,with inturned hooks or grasps, which are adapted to engage the beveled top flange20 of the pressing plunger E. 21 are leaf springs mounted on the yoke 16 and pressing outwardly on the fingers to. spread the same.
F is a ring provided with a pair of internalrecesses 22 with cam walls. Said ring surrounds the fingers 18 and is held against the lower face of the cross head by hooks 23 I depending from the cross head, the ring being slidable laterally inits mounting. -When the ring is rotated so that the recesses 22 register with the finger 18, the springs 21 spread said fingers apart'so that a pressing plunger maybe inserted in place or removed. When a plunger is inserted in place,
' the ring F is then rotated so that its cam surfaces force the fingers 18 together to properly grip the head of the plunger. The nut 17 is then screwed up on the shaft 4: to elevate the yoke'16, thus drawing up the fingers 18 .and securing the plunger rigidly to the cross head. Before screwing up the nut '17, the ring F and with it the fingers 18 and the plunger E may be adjusted laterally to properly center-and aline the plunger 7 with the mold or molds into which it is to shaft 4 assists in the lateral adjustment of the plunger, as the swinging of the fingers in connection with the tilting of the yoke does not loosen the grasp on the plunger.
