Specification of Letters Patent.

Patented April 14, 19Q8.

, Application filed February 25, 1907. Serial No. 359,063.

To all whom it may concern:

Be it known that we, IRA I'IAZLETT.

FREESE, JOHN W. Roman, and HARRY A. CAROTHERS, citizens of the United States of America, and residents of Clarksburg, county of Harrison, and State of West Virginia, have invented certain new and useful Improvements in Apparatus for Fire Finishing and Polishing Glassware, of which the following is a specification.

Th1s invention-relates to new and useful improvements in glass-finishing furnaces, and more particularly to an apparatus for fire-finishing and polishing glassware; and it consists in the particular construction, arrangement and combination of parts which will hereinafter be fully described.

The chief object of the invention is to provide a simple, efficient and convenient form of apparatus for fire-polishing articles'ofglassware as they are ta en from the press or mold and for rendering said articles sufficiently plastic to admit of their assuming or being shaped into finished form, correcting irregularities therein, smoothing the edges, etc. A further object of the invention is to provide a convenient form of machine of the character mentioned whereby the reheating and polishing of articles of glassware is greatly facilitated and having a greatly increased capacity for performing perfect work over most machines hitherto employed for the urpose.

A still further object is to provide a reheating furnace comprising a plurality of combustion chambers in front of which the articles of ware are passed, each of-said chambers being heated independently of the others, said furnace therefore being adapted for regulation to an extent which admits of a gradual reheating and a like cooling of said articles. And a still further object of the invention is to provide in connection with the machine, as hereinbefore referred to, a mouth-sha ing device whereby the articles of ware, whiih in a semi-plastic state after such reheating, may

be subjected to a shaping operation for cor-' recting irregularitiesin the open ends or mouths thereof.

Further objects of the invention are to construct a portable fire-finishing and polishing machine of which the furnace forms a component part; to provide a machine wherein relation to the ware-carrying portion thereof; and to provide novel and convenientlyarranged means for carrying the ware.

In describing the invention in detail, referonce is herein had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the invention complete, except for the omission of the conveyor-chain; Fig. 2 is a front end elevation of the same; Fig. 3 is a cross sectionon the line 33, Fig. 1; Fig. 4 is a top plan View of the invention except that one end of the furnace is shown in horizontal section; Fig. 5 is an enlarged detail view, partially in section, showing the mouth-shaping device; Fig.

'6 is an enlarged detail view, showing the ware-carrier in elevation; and Fig. 7 is a view similar to Fig. 1, illustrating a modified formation.

Referring to said drawings, in which like reference -numerals designate like parts throu hout the several views1 indicates a bed-p ate or base of any preferred form which is preferably'mounted upon wheels or rollers 2 and has, mounted thereon a frame 3 which supports a horizontal table or track 4 of oblon or elliptic form. Also sustained by said be -plate at suitable points is a plurality of hollow pillars 5 into which extend the lower ends of standards 6 which have horizontal metal support 7 for sustaining the base or bottom 8 of a longitudinal furnace 9,

said base or bottom 8 being surmounted by an arched crown IQ of suitable form.

The lower end of each standard 6 is threaded and is mounted in the interiorly-threaded hub 11 of a gear-wheel. 12 which surmounts the pillar 5, being suitably held in place by an appropriately formed plate 13. Cooperating with the gear-wheels 12 are worm-gears 14 which are fixed upon a longitudinal hori-v zonta'l shaft 15 which is suitably journaled, as in bearings 16 sustained by the frame 3, said shaft bearing upon one end in a convenient position at the front end of said frame a hand-wheel 17 by means of which said shaft is rotated. As is obvious, by rotating said shaft motion is communicated to the gearwheel 12, which latter being interiorly threaded and having the standards 6 mounted thereinjimparts'an elevating or lowering movement to said standards, according to the direction of rotation of the shaft, for raising and lowering the furnace with respect to the table or track 4.

Journaled in bearings 18 and 19, the former mounted upon the bed-plate at its front end and the latter sustained by the frame 3, is a vertical shaft 20 which is driven in any suitable or appropriate manner, as by a motor 21 whose drive-shaft 22 bears a wormgear 23 in intermeshing engagement with a gear-wheel 24 carried by said shaft 20. Fixed upon said shaft to rotate therewith is a large sprocket-wheel 25, and journaled in a suitable bearing .26 beyond the rear end of the furnace and on a horizontal plane with said sprocket-wheel 25 is a second sprocketwheel 27, said sprocket-wheels being connected by an endless sprocket-chain 28 of peculiar and novel construction.

-The sprocket-chain 28 consists of a plurality of alternate pivotally-connected sprocket-links 29 and ware-carriers 30, and said ware-carriers each consists in part of an upright, body-portion 31 having a bifurcated lower end in which is mounted a supportingwheel or roller 32 and having upon its upper end and preferably inte al therewith a yoke 33. A revoluble spindl d 34 having a wareholder of appropriate form upon its upper .end has its bearings in suitable bosses 36 and 37 carried by the members of said yoke, and fixed upon said spindle intermediate said members is apinion38 adaptedfor constantly standing in operative relation to a toothed rack 39 which wholly encircles. the furnace 9 and is sustained at a suitable height above the table or track 4 by supports 40 whose lower ends rest upon said table or track, as shown in Figs. 1, 2 and 3.

A pair of lateral lugs 41 are provided on each of the opposite sides of the body-portion 31, to which the ends of the links 29 are pivotally attached.

As is ap arent, motion communicated to the vertica shaft 20 is communicated to the chain 28 and said ware-carriers 30 are consequently carried forward, traveling upon said table or track 4. v a

For a purpose which has already been referred to and which will hereinafter be more fully explained, the longitudinal furnace 9 is divided by partition-walls 42 into a plurality of combustion chambers 43. A gassupply pipe 44 leads into each of said chambers, preferably through the metal support 7 and furnace-bottom 8, each separate supply-pipe being provided with a valve 45 by means of which the fuel-supply to the various' combustion chambers may be regulated.

The bottom or floor 8 of the furnace extends laterally at one side near to the path of travel of the ware-carriers, and the crown 10 has a lateral substantially-horizontal projecting-ledge 46 which overlies,or partially overlies, said path of travel, and a suitable restricted discharge-openin or passage 47 is provided between said oor 8 and said ledge 46 through which the products of combustion emanating from said chambers issue upon the glass articles 48 passing adjacent thereto. Extending along the under side of the ledge is an integral longitudinal bead or rib 49 which constitutes a deflector for directing the heat and gases of combustion issuing from the combustion chambers of the furnace into the mouths, as well as upon the tops or upper edges, of said glass articles 48, as is clearly shown in Fi 3, for quickly melting the edges of, and aso for fire-polishing, said articles.

The provision of the division-walls dr partitions 42 forms, as hereinbefore stated, a plurality of combustion chambers 43 which are, in effect, separate furnaces, each having its own fuel or gas sup 1y controlled by a valve whereby the heat t ereof may be regulated as desired. As a result of this arrangement or construction of the furnace, it will be noted that the degree of heat emitted by the various chambers may be varied as desired'or as may be found w produce the best results: as, for instance, the end-chambers of the furnace may be adjusted to emit only a moderate degree of heat, and the central chamber or chambers adjusted to emit an intense, or high degree of, heat, provision thus bein made whereb the glass articles against w ich the heat lasts are directed are gradually heated and again gradually cooled during their passage in front of the restricted discharge-openings or passages 47.

Mounted upon the vertical shaft 20 at a suitable point is a fixed collar 50 which supports a loose collar 51 having hin ed or pivoted thereto the end 52 of a han -lever 53, which latter is adapted to be employed for lowering a rotary mandrel r mouthshaping plunger 54 which is carried thereby into contact with the glass article. Said mandrel is preferably hemispheroidal in form and has an integral stem 55, on the upper end \of which is a sheave 56 which is connected by an endless belt 57 to a sheave 58 mounted on mandrel is constantly rotated.

As shown in Fi 5, the stem 55 of the mandrel is rotata le within a verticallyslidable sleeve 59 which is mounted in the lever 53 at a suitable point. Screwed up within a threaded socket provided in the under side of said lever 53 is the sleeve 60 of a bushing 61 which loosely encircles the upper annular edge of the mandrel when the latter is raised to the limit of its upward movement. Said bushin 61 is provided seatsand has a bell-mouth 63 adapted for lthe reception of the upper edges of glass said shaft 20 and by means of which said with a cup-socket 62 in w ich said mandrel articles of varying sizes when said lever is lowered over said articles. A second lever 64 for raising and lowering the mandrel with respect to the lever 53 is pivotally mounted upon an upright lug 65 as a fulcrum, said lug being provided upon the lever 53 at a suitable point between its free end and the stem 55. The front end of said lever is pivotally connected to the sleeve 59 in a suitable manner, a yoke being preferably formed inte ral with said front end, the members 66 of w ich are pivotally mounted upon lateral pintles 67 carried by said sleeve 59. As a means of normally sustainin the sleeve 59 and, therefore, the mandre in depressed position with relation to the lever 53, a suitable spring 68 is mounted in appropriate position between the lever 53 and the lever 64, as shown. For rendering the length of the downward thrust of the mandrel adjustable, a vertically movable stem 69 is ivotally attached at its upper end to the ever 64, said stem being projected through the lever 53 and having upon its lower threaded end an adjustin -nut 70 by means of which the movement 0 said lever 64 may be limited.

The operation is as follows: The articles of glassware are placed upon the holders 35 carried by the ware-carriers as the latter pass from the front end to therear end of the machine, traveling on the table on the rear side of the furnace. As the ware-carriers rogress, the ware is borne around in front 0 the furnace with its upper edge directly in front of the discharge-openingsand is sub'ected to the heat blasts and flame issuing rom the various combustion chambers, the deflector 49 serving to direct said heat and flame u on the passing articles and to cause it to p ay within as well as without the ware. The glass articles are rotated by the rack and pinion mechanism, exposing their parts to the heat and causing t em to be evenly heated and an even polish to be imparted thereto. The softening of the glass produced by such reheating results in the edges sinking down and assuming aperfectly smooth and even form. Having been subjected to the heat blasts of the furnace, the ware asses around .to the semi-circular front end of the machine. For the purpose of correcting any irregulari ties in the mouth of the ware which may result from the reheating, such, for instance, as a slight flaring or cupping of the glass, the

operator, as the glass article rounds said front end of the machine, lowers the lever 53 over said article, bringing the mandrel 54 directly into the mouth thereof. Said mandrel, being rotated rapidly, quickly reshapes' the article. The collar 51 to which the lever 53 is pivotally attached being loose upon the shaft 20, said lever is permitted to 'move freely around said'front end of the machine with the moving ware. Said lever is again upraised before a point outside the peripheral rotation of the sprocket-wheel 25 carrying the chain 28 is reached.

It will be noted that the furnace is made adjust-able with respect to the track or table 4, which latter is preferably stationary, in order to provide for the adjustment of the discharge-opening or passage with respect to the ware borne by the ware-carriers. This is rendered advisable since glass articles of varying sizes and shapes may be made the subjects of such reheating and polishing. In order to admit of the vertical adjustment of the furnace without disarranging the gassupply pipes 44, which latter are preferably stationary, a guide-way is preferably provided, as shown in Fig. 7, for the reception of the upper, or free, end of each of said pipes, said guide-way consisting of a metal cup-shaped bracket'71, having an orifice .72 in its bottom, attached to the under side of said metal support 7, and having a fire-clay lining 73. The pipe 44 being stationary and having its upper end loosely held in the passage 74 of said guide-way, a considerable range of vertical movement of the furnace is admitted. Air-blast pipes 75 are also referably provided in connection with saic gas ipes 44, as shown in Fig. 7, for producing a orced blast, the purpose of which is well understood.

The metal support 7 may be plain and flat, as shown in Fig. 1, but is preferably tapered, as shown in Fi 7, to cause its upper face to stand inclined for holding the furnace 9 in an inclined position withrespect to the table or track 4. The object or pur ose of the lastmentioned arrangement of tie furnace is to cause the discharge open-ing 47 to stand inclined whereby the heat blasts emanating therefrom are first directed against the bottom ends of the glass articles and gradually move upward along said articles as the are carried forward until at the front end 0 the furnace said blasts are directed against the tops of the articles. The result of this arrangement is that all parts of the glass articles are subjected to the polishing action of the heat and flame, and that the ware is gradually heated from bottom to top, the latter being in a semi-plastic condition when the mouthsha ing position is reached. 1
