Attorney Patented Jan. 20, 1931 UNITED STATES J'OSEPE C.'KELLY, QF SAND SPRINGS, OKLAHOMA SNAP-REVOLVING MACHINE Application filed. February 1, 1930. Serial N'o. 425,159.

My invention relates broadly to the manufacture of glass articlesand more'particularly to a warming in machine for all kinds of glass ware which may need refinishing or reshaping. It is adaptable for lamp chimneys, lantern globes, tumblers, bottles, jars, etc. i

. Previous to my invention diiiiculty has been experienced in obtaining a correct and evenly distributed heat for the several articles. this art the several glass articles are held by snaps or'punties. These snaps are revolubly supported between aligned parallel discs and adjusted so'as to maintain the articles in front of the respective finishing holes. The finishing. holes are usually formed in a curved wall and hence it is very difficult to align all of the glass articles so that proper heating occurs.

I overcome the above dificulty by placing several banks of supporting devices along radii of the usual circular furnace or glory hole. These banks, two of which are shown in the accompanying drawing, are mounted on a single frame and driven by a single prime mover. They form a device which is adapted to cooperate with my arrangement of finishing holes in-the curved wall. Thus,

it will be seen, that the flames and hot gases rush out through the finishing holes exactly in alignment with the articles to be heated. Thus uniform heating prevails.

Furthermore, if desired, one of the wheels or discs of the pair which support the snap,

may be rendered slightly eccentric by making it revolve about a sixty-fourth of an inch oflf center. This causes the snap to move about twice this distance in an upwardly and sidewisedirection. Hence, the glass article not only revolves in its bath of heat but also 7 travels in a small orbit which insures equal heating of all of its portions.

Another advantage lies in the fact that the V-construction of my frame allows the operator ready access to any of the snaps.

Other objects of this invention will be set forth in the following description and drawings which illustrate a preferred embodiment of this invention, it being understood As is well known to those skilled in cipal difference being thatone' is that the above general statement is extended merely to generally explain the same and not to limit it in any'manner.

In the drawing Flgure 1 1s a plan vlew of my invention;

Figure 2 is a view in cross section taken along the line IIII of Figure 1.

Figure 3 a view of one ofthe banks of snap holdersjlooking in the direction of the arrow A of Figure 1. V

Figure 4 is a side view oftthe frame which supports the banks or supports for the snaps.

banks or sections are supported or consist of,

in part, a frame 'F which is recessed out to form an .open' space J which allows the operator access to the several'parts. The frameworkof. each bankis similar, the prinleft hand and the other right hand. 7 a A furnace or glory hole Gr has finishing holes 21', -31, 41, and -51.- Shafts 22 and 23 form a revolving unit which is exactly in line with the parallel holes 21. and 31. Shaft 23'- has adiscs r62'fastened thereto as shown. Shaft 22 has discs or wheels 62 p and 163 rigid therewith and aligned with or opposed to discs on shaft 23.

As shown in Figure 5the disc -63 has.

a geometrical center -K, and an actual center of revolution L-. The distancebetween these centers is M and hence the i camming action is equal to twice M. Thus the snap S is lifted a vertical distance V and shifted horizontally a dis- Shafts -32 and 33' areparallelto shafts 22 and 23' and have discs 62- rigid therewith as clearly shown in Figure 1. -All four of these shafts are revolubly mounted in brackets 64. Snaps are laid between the discs of each of these unit-s and the drive shafts 23 and 33 rotate them. Rotation is transmitted from shaft -33 to 23 by means of pinion or sprocket wheels" 66 and 67 and chain 68.

A shaft 70, mounted in brackets 7 1, has a bevel gear 72, which meshes with the bevel gear 73 to drive the shaft -33. The shaft .70 is rotated by means of a gear 74, thereon, meshing with a bevel gear 75 on the shaft -f2-.

Shafts 42 and 43-, with discs 62 juxtaposed, rotatably mounted in brackets 64 (not shown), form another unit for revolving a snap. The snap S is shown in dotted lines. Note that the snap S- is directly in line with the finishing hole A1.

A gear -76 is connected to any suitable prime mover, not shown, to motivate the several units, and sprockets -77 and -78, interconnected by chain 79, drive shafts 4:2 and 52 in synchronism.

Shaft 53 cooperates with shaft 52 to form the last unit. Shaft 53 has an off center disc 6'3, similar-to shaft 22, which causes the article T to travel in an orbit.

Figure 2 shows the chain connection between shafts --42 and Also, chain 80 leads to any suitable prime mover. Figure 8 shows small arrows X which indicate the direction of rotation of the discs.

The operation is readily understood. The articles to be heated are simply placed in the snaps and then laid between the proper discs. The snap rolls between the discs and consequently does not sag or flow downwardly. Moreover, it is heated evenly. In the case of the outer snaps slight orbits are 7 caused bythe eccentric discs. This makes for even better heating.

Vhat I claim is 1. A snap revolving machine for an arcuate glass furnace consisting of two banks of units; means for supporting each bank radially with respect to the furnace; each bank consisting of two parallel units; each unit consisting of two parallel shafts, one a driven shaft; opposed discs on the last mentioned two parallel shafts; brackets to revolubly support all of the shafts; and means to rotate the driven shafts.

2. A snap revolving machine consisting of a set of two shafts, means for revolubly mounting the shafts in parallelism, means for driving one of the shafts, discs near either end of either shaft fixed thereto; another identical set of shafts and appurtenances; and means for maintaining saidv last mentioned set of shafts at an angle to the first mentioned set.

also having the several discs at either end of either set of shafts in alignment.

4. A machine as set forth in claim 2 but further characterized by the fact that the means for driving the last mentioned set of shafts is motivated by the first mentioned revolving shaft.

5. A device of the-character described having several sets of snap revolving mechanisms not in alignment; each set comprising two shafts, means for revolubly mounting the shafts in parallel relationship; opposed discs on the two shafts, and means for revolving one of the shafts.

6. A snap revolving unit comprising two parallel shafts, brackets for revolubly holding same in parallel relationship, two discs on one of the shafts, two discs on the other shaft in the same plane as the first mentioned discs, one of said discs being slightly eccentric.

7 In a snap revolving machine having two parallel shafts with discs thereon the combination of means to rotate one of the discs about a pivot slightly distant from its geometrical center.

8. An apparatus of the character described consisting of a structural V-shaped frame having two brackets along either side of the V, shafts mounted in the brackets, discs on the shafts and means to rotate the shafts in JOSEPH C. KELLY.
