Beit known that LWILLIAMF. KoEPPEN-,of

Marion, county of Grant, and State of Indiclear, and eXact description thereof,reference being had to the accompanying drawings, in

which like numerals referto like parts.

This invention relates tofmeans for open; ing and closing 1nolds,and is especiallyadapt-v ed for use with bottle or other kinds of' glass molds.

` The object ofthe invention is to provide means for so separating the mold-sections in opening the mold as not to rinjure the glass article blown or otherwise-formed therein.

It has been the common practice to hinge or pivot the two sections of a glass-mold toa common means and to open the mold or separate the sections thereof hy turning the moldsections back on their pivots. Such movement of the mold-sections causes them to move from the glass article in a curve and often toinjure the portion of the glass bottle -or jar therein that-'may be in relief-as, for

example, the panels or the rectangular corners often seen in bottles. The means I have provided overcome this difficulty, as the moldsections are moved directly on a straightlateral line away from the thing molded and away from each other. In order also to insure the opening of the'molds without in any v wise injuring the bottle or article therein, the

, and from the article therein.

means I have herein provided are such as to move one mold-section at a time. "First one section is removed while theV article is still held by the other section, and then the seoond section is removed. This prevents in# jury to the glass article that so frequently ocV curs when the two sections of fthennold, are separated simultaneously from each other The general nature of theinvention willbe understood from the accompanying drawings and the following description and claims.

Figure 1 isa plan of' the device, one sec-'- tion of the mold being open.` Fig. 2 is a side elevation of the same. Fig. 3 is a cen-v tral vertical section of thesame. Fig. 4 is a bottom View when the' mold-.sections are closed. Fig. 5 is the same when one moldin Figsrl, 2, and 3.- -Fig. 6 is the sameshow# section has been opened tothe positionshown p 1'" f In thenaccompanyingdrawings. vthere kis showna table or stand 10whose top isy cir- Y ,cularand which is supported by segmental legs 11.-Y Upon said'stand or table a pair of parallel A-sh'ap'ed ribs 12 are Aprovided that extendY diametrically across theV table'avnd equidistant from thecenter thereof. lAt the center of the table or stand I secure a mold-f' i bottom' and centering-block 13, `heldin placefv by the screw 14, that extends through a` suit-V able hole in the table or stand.10.v i l The mold is formed of the half-,sections l5.l and 16, secured, respectively, to the slidingv` plates 17 and AIS-by the screws 19,. On the under side Asaid sliding blocks areprovided with A-shaped grooves (not here shown) thatr correspond and fit over the ribs 12, and by this means the sections ofy the mold are guided in their movementtoward and awayV from` .y These slots are placed-0n opposite sides of the center of the disk 20, and the inner portion of slot 23 and outer portion of the slot j 22 are concentric with said disk, and'one is near'said center and thev other vfar fromit.

The inner end of the slot 22 is curved slightlyA eecentricwith thel center of the ,disk and ap` preaches the said center as closely as the in- `i ner end of thefother slot; while the outer portionof the` other slot 23 isv simil-arly curved and is `formed and far removed from the cen'- `9'@ ter of the disk so thatouter ends of the slots,

as shown, areequidistant fromthe center of i through the slots 22 and 23 and have on the, llower ends headstoprevent their escape, as

The function of t appears in the drawings.

Pins 24, secured'in the sliding plate 20,' with the slots 22 and 23, is to move the sections of they molds away and toward each other bythe connecting-pins 24".A Such movement and mode of movement will beunderstood vfrom the following explanation: When the mold has receivedits charge of IOC glass and is closed, the sections being against each other on the under side of the disk 20, the bolts 2i are at their inner limit of movement in the slots 22 and 23.' The pins are then equidistant from the center, andthe parts are in the position shown in Fig. 4. After the article has been blown and it is desired/lo open the mold the handle 2l and disk 2O are moved from the position shown in Fig. l to that shown in Fig. 5. During such movementofthe disk the bolt 24 is moved only through the portion of the slot 23 Which is concentric with the disk 20, and since said bolt has not been moved farther away from said center the moldl5,`to which said pin is secured, has remained stationary, as shown in Figs. 1 and 2; but such oscillation oi' the disk 20 has caused the other bolt 24, extending down from the mold-section 1G, to be moved from the position shown in Fig. et to that shown in Fig. 5, and such movement has withdrawn said mold-section 16 on a direct line laterally from the other moldsection and The article molded to outer limit of movement. Then the disk 2O `is further oscillated from the position shown in Fig. 5 to that shown in Fig. 6, during which the bolt 24; from the mold section 15 travels through the slot 23 to its outer end, and consequently moves the mold-section 15 away from the molded article to its outer limit of movement. During such movement of the mold-section 15 the other mold-section has not moved, as its bolt 24: has merely passed through the concentric portion of the slot 22. The article molded may then be removed and the mold-sections brought into position for another charge by reversing the movement ot the lever 2l from the position shown in Fig. G to that shown in Fig. l, and during such reversal the mold-section 15 will first be brought to the closed position, ready for a charge of glass, and then the mold-seclion 16 be moved to the closed position.

IVhat I claim as my invention, and desire to secure by Letters Patent, is

l. In a mold opening and closing device a pair of mold-sections, a guide for the lateral movement thereof in opposite directions, pins extending from said molds, and an oscillatory plate with slots therein into which said pins loosely extend, said slots being so arranged that when the plate is oscillated it will cause one of said mold-sections to be moved in advance of the other.

2. In a mold opening and closing device, a pair of mold-sections, a stationary plate beneath the moldsections with slots therein in line with each other and with the center of the mold, pins connected with the mold-sec tions and extending down through the slots in the stationary plate, and an oscillatory plate below the stationary plate with slots therein for receivingthe lower ends of said pins, said slots being so arranged that when the plate is oscillated itwill cause one of said mold-sections to be moved from the center in advance of the other.

3. In a mold opening and closing device, a pair of mold-sections, a guide for the 'movement` thereof, a plate mounted concentric with the mold-sections when closed having a concentric slot on one side of its center and an eccentric slot opposite thereto, the inner end of the eccentric slot being diametrically opposite the inner end of the concentric slot and equidistant from the centerof said plate, and means extending loosely through said slots and rigidly connected with said moldsection for moving the latter when said plate` is moved.

4. In a mold opening and closing device, a

pair of mold-sections, a guide for the moldseetions, a plate mounted concentric With the mold when closed having on one side ot the center a slot that is concentric at its `inner end and eccentric at its outer end, and an eccentric slot on the other side of the center of said plate with its inner end diam etrically opposite the inner end and at the same distance from the center ot the plate as the concentric portion of the first-mentioned slot, means for giving said plate rotary movement, and means extending loosely through said slots and rigidly connected with said mold-sections.

5. In a mold opening and closing device, a stand having openings in it, a straight guideway, plates slidable on the stand and controlled by said guidevvay, mold-sections secured to said sliding plates, a plate rotatably mounted under the stand and concentric with the mold when closed, means for oscillating said plate, a pair of slots in said plate on opposite sides of the center, one slot having its inner portion concentric and its outer portion eccentric with the center of the disk, and the other slot having its inner portion correspondingly eccentric and at its outer portion concentric with the center of said disk, and bolts extending down from .the sliding plate through the openings in the stand and through said slots.

In Witness whereof I have hereunto aixed my signature in the presence of the witnesses herein named.

IVM. F. KOEIPEN.
