Specification of Letters Patent. Patented J an. 11, 1921.

Application filed August 8, 1919. Serial No. 816,102. l

To all whom it may concern.' l

Be it known that I, ALBERT B. KNIGHT, a citizen of the United States residing at Fairmont, in the county of 7Marion and State of West Virginia,have invented c'ertain new and-useful Imrovements in Machines for Burning or lazing the Edges and Sides of Glassware, of which'the follow- :ing is a specification.

This invention relates to. new and useful improvements in machines for burning or glazing the edges and sides of glassware.

An important object ofthe invention is to provide means for simultaneously glazing necessarily be of some length as the machine must be used for glazing very short tumblers as well as the long stemmed type to be of any practical value. A

In my construction, instead of raising or lowering the spindles themselves, I have provided a carrier for the spindles which may be raised or lowered, thereby removing the thrust from the lower end of the spindle. 'Other objects and advantages lof my invention will be apparent durlng the course of the following description. l

In the accompanying drawingsV forming` a part of this specification and in which like numerals are employed to designate like parts throughout' the same,

Figure 1 is a'side elevation of my machine, i

Fig. 2 is a section taken on line 2-2 of Fi 1 ig., 3 is a section taken on li-ne 3-3 of Fig. 2, p

Fig. 4 is a section taken on line 4 4 of Fig. 1,

Fig. 5 is a section taken on line 5-5 of Fig. 1,

Fig. 6 is a section taken on line 6-6 of Fig. 1,

Fig. 7 is a section taken on line 7-7 of Fig. 1,

Fig. 8 is a plan view of the drive for the machine,

ig. 9 is a front elevation of the burner, an d Fig; 10 is a section taken on line 10-10 of F 4.

Re erring now more particularly to the drawings, the numeral 10 indicates a suitable base upon which is mounted a socket ange 11, having a socket 12 formed therein.

Seated in the socket 12 is a vertical shaft 13, -which is held against rotation by a set screw 14.- or `the like. Seated upon the 'upvper end of the Vsocket flange 11 is' athrust bearing 15, upon which is'mounted a sleeve 16, 'surrounding the shaft. The sleeve 16 is provided upon its lower end with an outstanding flange 17, to which is secured, by means of bolts or the like, a sprocket gear 18. Secured to the base 10 is a support 19, to the outer end of which is secured a vertical member 20 having upper and

lower brackets

21 and 22 secured thereto. Rota-4 tably mounted in journals formed in these brackets is a vertical shaft 23, provided upon its upper end with an operating handle 24. Adjacent its lower end, vthe shaft 23 is provided wxidthba sprocket gear 25, alinedwith the...spr.ocket gear 18 and connected thereto with a chain 26. It will be readily seen that when the handle 24 is rotated, the sleeve 16 is rotated simultaneously therewith.

The sleeve 16 is provided upon its upper end with external screw-threads 28. Mounted upon the up er end-of the sleeve 16 is an internally t readed sleeve 27, the internal threads of which engage with the external threads 28 of the sleeve 16. The upper end of the sleeve 27 has an inturned flange 29, having a central aperture adapted to receive the vertical shaft 13. Mountedl upon the flange 29 is a .thrust bearing 30, or its equivalent, upon which is in turn mounted a hub 31, having radial arms 32, which distend a gear 33.

Secured, upon the base 10 is a standard 34 embodying

journals

35 and 36. Mounted in these journals is a vertical tubular member 37 to which is secured a gear 38. This gear, in the present instance, is shown as comprising a worm gear which meshes with a worm 39 formed upon the shaft of a motor 40. 7The tubular member 37 is r0- vided with a vertical slot 41, and provides at its upper end a bushing 42, forming a journal to receive a shaft 43. The lower end of. the shaft 43 has an enlarged portion 44, having a'sliding fit with the interior of the tubular member 37 and is provided upon this enlargement with a pin 4 5 engaging in the vertical slot 41. Adjacent its upper end, the shaft 43 is provided with spaced lianges 46 and 47. Secured to the sleeve-27 is a bracket 48, provided with an extension 49, adapted to receive the shaft 43 between the ilanges 46 and 47. The shaft 43 is provided uponits upper end with a pinion 50, meshing with the gear 33.

A bracket' 48 is secured to the sleeve 27 and this bracket is provided with a plate 49, having an opening therein for the'reception of the sleeve 43, the plate 49 being adapted to be arranged` between the flanges 46 and 47. j

It will be readily seen that the bracket 48 and its extension 49, engaging the shaft 43, perform a two-fold purpose, the shaft 43, being incapable of transverse movement,` prevents rotation of the sleeve 27 and the sleeve 27, and its'bracketwhen raised or lowered by the rotation of the sleeve 16, will move the shaft 43 correspondingly. As the hub'ofthe gear 33 rests upon the upper end of the sleeve 27, it will be readily seen that the pinion 50 is kept in permanent engagement with the gear 33 and rotation of the sleeve 37 transmitted to the gear 33 by means of pin 45, shaft 43 and pinion 50.

Secured to the upper face of the gear 33 by meansof bolts y51 or the like, are a plurality of radial arms 52. These arms are provided u on their outer ends with substantially -shaped frames 53, `providing s aced journals 55, affording a support for t e bottom of the spindle. Secured upon the spindle 56 intermediate the journals 54 and is a pinion57, the purpose of which will hereina ter appear.

Mounted upon the upper end ofthe hub 31 of gear 33 1s a hub 58, rotation ofthe hub 58 beinsnr prevented by means of screws 59,

' or the h e engaging in key-ways 60, formed in am sima 13. The hub 5s is pmvideawith radial arms 61, distending a gear 62, meshing with the pinions 57 secured to the spinj dles 56.

iAt spaced intervals, as for example, at Aintervals of ninety degrees, I prefer to provide rollers 63, secured to the spindle journals 54. These rollers rest upon the upper face of the gear 62, and have a tendency to relieve the torque upon the gear 33, placing a ori tion of the Weight upon the gear 62. he spindles 56 are provided upon their upper ends with the usual sockets 64, adapted to receive the base of the tumbler to be glazed.

Secured to the upper end of the shaft 13 by means of a flanged bracket is a support 66. Secured to the support 66 inany and that the openings 70 are arranged u on a curved line. The casing 68 is connecte bymeans of conduits 71 with a suitable source of combustible fuel supply 72. Secured upon the upper peripheral edge of the casing 68 is a receptacle 73 having a filler 74 composed of refractory material, such as fire clay. It will be seen by'examining Fig. 2, that the openings 69 direct a jet of flame against the lire clay and the heat of the flame is reflected downwardly upon the edge of the tumbler. The fire clay is formed tapered outwardly so that the hottest rtion of the flame is spacedv as far as feaslble from the upper edges of the tumbler andthe outer edge of the flame is brought as close as feasible to the tumbler. The purpose of this tapered construction is to apply to the upper ed e of the glassware a uniform heat.

'he operation of m device is as follows:

The tumblers are p aced in the sockets 64 of the spindles 56 and raised or lowered by rotating the handle 24 until the tumblers are in .the pro er spaced relation with the fire clay 74. he burner 67 is then ignited and the motor started. The arms 52 being fixed upon the gear `33 are rotated therewith and as the gear 62 is fixed against rotation,

the spindles 56 are rotated through the mea dium of the pinion 57 meshing with the gear 62. It will be seen that the tumblers are simultaneously advanced and rotated. As the tumblers pass beneath the fire clay 74, the up r edges thereof are glazed by the flamev rected from the openings 69. The sidesv of the tuinblers are simultaneously glazed by the staggered openings 70 and by reason of the peculiar construction of this row of openings, flame is directed to all parts of the outside of the'tumbler.V Y

It is` to be understood that the form of my invention herewithv shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may beresorted to without departingfrom the spirit of my invention or the scope of the subjolned claims.
