all whom it may concern: Be it known that I, BENJAMIN D. CHAM- merica, and a resident of the city of Corno infe State of New York, have invented certainneW and useful Improvements in Glass- W'Orking Machines, of which the following a specification. V r This invention has for its object to prolqf'yide mechanism to automatically marver a "mass ofglass which has in any approved manner. been gathered, collected, or placed ,ufpon a glass working spindle. I The apparatus shown in this divisional application (which is a division of my preyinus application filed March 23, 1910, Serial No; 551,198 )has for a characteristic feature the use of a rotating, -1113lV:11,1tl1 mar-yen in}: surface of which is so shaped that in the rotation of the marverer successivipoints ,thereotar'e brought into contact with the glass. and that such successive contactpoints are each slightly closer top-the axis of the n'lassworking spindle by which the glass is 1 carried. In the specific embodiment shown herein for this purpose, the marverer a has the transverse cross section of a spiral, and the long-itudinalsection of the frustrum of,,a cone, themarvering surface vbeing; the interior surface of a spiral wall, which wall isfcarriedby a hubsuitably mounted to peryinit its rotation to bring the successive points thereof in contact the diameter of the latter. I Avsuitable marve rer of the general character before stated is associated with mechanism by which it may ,be rotated and by which: the spindle is held :in proper fixed cooperative position therewith, In the spe- 4 cific, form of mechanism here shown, the operating mechanism for the marverer comprises means for intermittently and reversely rotating it; and the mechanism for sup-- porting the spindle embodies means whereby the spindle is lifted to a position slightly above the horizontal, to bring and hold the glass thereon into proper cooperative relation with the marverer. and furthermore embodies means for rotating the spindle around its longitudinal axis whereby in the or conmnev new yonrzfessiouon av nun, afcitizen of the United States of I struction which it is desired to avoid.

"ii an mounted thereon 'l'or rotain, 2 carrying; thereon the carrying head 5, the sleeve 3 being rotated by any suitable mediauisrn (not shtmn). The head is formed by a resting having a top plate 5, having two concentric annular walls 5 and 5 projecting downwardly from its under surface. The outer wall 5 is near the outer edge or theplate, but such. edge of the plate intcrru p l by a series of arms radially projecting from the plate 5 at regular intervals therearound. These arms each comprise top at l bottom flanges 7 and 7 connected by radial vertical webs 7 the informed. by the parts 7, 7' and- 7, the bars having on their opposite ends the bearings 9 and 9 to receive radial. shafts to be hereinafter described.

l The head carries an air-pumping mechalnism comprising a plurality of cylinders 10,

lpiston-actuating shaft 11 which extends upzwz rdly within the tubular. standard 2, and is su tably driven. The upper end of the shaft lyl projecting); wrist pin 13 on the end thereof ad ti: a pumps, which deliver air through the pipes ll into a re voir formed in the head between the annular walls 5 and 5. j

ln: ,much as the head 5 carries a number of complete mechanisms, which are rlup1icares of each other, one of such units being as )tlfllQLl with each peripheral arm formed the parts "5", '5, and 7". The following description will be drawn to one such unit, it being understood. that such units may be multiplied as desired. 7

he ends oi the top and bottom flanges 7 and l of the arm are extended outwardly h y-mid the web T thereof, and are formed in the we between which is mounted a hull yinp; Frame. This frame coma substantially triangular part which, has cars it? formed thereon. lohe ears '7 of the arms, the t of cars beings; articulated together cove l? to which the upper ear 1G H i and which projects through a hearingin the 7", while the lower ears are articulated together levy a pin 18. The sleeve 1? extends upw 'dl' above the ears 7 and. has fast on its upper end {1 Q0111 17" which meshes with a rack i carried upon the outer end of a, bar mounted for radial movement on the to lots 5", the inner end her ends of which join the exterior of thewall 5?, and the top flanges '1 of which form Betweeniarranged around the upper end of their 16. beveled pinion 23 which meshes with, and is of said bar having, a stud roller 17 thereon engaging a cam-way inthe lower face of a plate 20 carried upon, and held. against movement by the top of the standard 2 and located about the top plate 5".

It will be seen that the bar 17 will par take of the movement of the head around the standard, and that it will in consequence thereotibe given a radial movement dependout upon the shaping of the cam with which it engages, and that in such radial move- .ment it will, through the pinion 17 and sleeve 17 turn the carrying frame 16 upon the vertical axis formed by such sleeve and by the pin 18. The cam is so shaped'that in the rotation of the head, the frame 16 will, in the rotation of the head, he turned to different angular positions around its pivotal mounting on the head. Among the various functions resulting from these angular movements of the frame may be the projection into and withdrawal of the spindle from the furnace, and the positioning of the horizontal pivot of the spmdle (to be hereinafter described) to permit the spindle to be brought into proper co-operative relation with the marverer and with the blowing and molding mechanism.

The structures above referred to are fully disclosed in my original application afore-J said, and need no further description herein as the same db" not in themselves form the .s'ub ect-matter of clalms 1n this application. .l'l. carries a. crank arm 13 havlng an upward-v At the apex of the car'rjvin frame 16 is 'formed a bearing for the spin e-support 21, pted to actuate the piston rods 14 of such support having a trunnion 21 which is horizontally mounted in the apex of the carrier, *so that the glass-carrying spindle a vertical plane. For the purpose of moving tho glass-carrying spindle in a vertical plane around its trunnion mounting, a beveled gear 23 is keyed to the free end of the trunnion, and is driven through a pinion 23 fast on the upper end of a horizontal shaft 23" contained in hearings in the frame The shaft 23 has on'its-inner end a driven by a corresponding pinion23 mounted on the pin 18 and fast to the gear 2 3'. A vertical shaft 24 is-mounted in the arm 7 near the bearing"? and has fast on its lower end apinion 241 meshing with a gear'23 and has on its upper end a gear 24. which meshes with the outer end of :1 rack bar 24", mounted 'l'dr radial movement above the top plate 5, the inner end of such bar having: a stud roller 24 on the lower taco thereoftaking" into a cam-way on the upper face of the fixed plate 20. It will. be seen that the bar 24 over-lies the bar 17 which swings the frame 16, and that like the bar 17 the bar 24 will partake of the movement oi the head around the standard, and that will in consequence thereof be given a radial s with heveledTge'er 21 manent' connection, or

The lower end of the lever carries a roller 83" taking;- into a cam track upon the upper face of the cam plate 20. this eain track being so shaped as to. at different times, hold the clutch block lllltl'- mediate of the gears 80 and 80 or in engagement; with one or the other of them; The beveled pinion T8 upon the. horizontal shaft 78 is mutilated, that is to say has the. teeth upon a portion or its peripher cut away, whereby when such multilated portion of the pinion comes into the line of centers the driving effect ol the shaft Th upon the niarverer carrying-frame Tl' will be lost, but at other times the rotation of the shaft 78 will cause a movement o l' the marveling frame around its horizontal not. A second Wheel St is formed upon the horizontal shaft 78 and either meshes or frictionally drives a corresponding: wheel hl formed upon the inner end of the marvcrer shaft. I

The operation of a machine such as that heretofore described is as follows The rotation of the head 5 around the central standard causes movementsof the various parts driven thereby. and at some interval of such rotation (preferably immediately after a gathering. has been effected by the blowpipe or immediatcl; after a glass-Working spindle having an mitormed gather of glass thereon is inserted in the machine). the marvering shaft 75 will he erect, and the glass-working spindle will be projected from the head at some angle to the radius on which the vertical pivot by which. it is mounted is located. and at some angle in respect to the horizontal. \Vith the parts of the unit under eensideration in this position. the mutilated portion of the pinion 78 of such unit is at the line of centers and the clutch block 82 is intermediate of the two gears RO'and 80. being held in this position by itsiactuating cam rim. The contini. 4d rotation of the head will now cause the lever 83? to enter such art of the cam run as will throw the clutch block to lock the gear 80 to the horizontal shaft 78. This results in a rotation of the horizontal shaft in such direction as will cause the toothed portion of the beveled pinion 78 to engage the beveled gearing: 76 upon the marverer frame to cause the m'arverer frame to descend to the position shown in full lines in Figure. 2. After the descent ,of the inarverer. the mutilated portion of the pinion 78 will again come into the line of centers, and the continued rotation of the horizontal, shaft will no longer all'ect the position of the marvering frame. Simultaneously with these movements of the marverer frame, 'the glass-carrying spindle has been. swung upon its horizontal pivot: to place it in the plane of the marverer. and the end thereof having the glass thereon has been raised (if it was not. al -ady in this position) so that the gather is in position to enter the mouth H of the spiral of the maiverer, when the latter has been lowered to its limit (see Fig. 3), it maintaining a fixed. position during the marveriug. v.

The lowering of the marverer brings the wheels 84 and 8.4? into engagement with ear-h other. and results in a rotation of the marvercr shaft and of the marverer, which,

combined with the rotation of the glassearrving spindle upon its longitudinal axis results in the formation of the gatherer. The direction of rotation of the spindle is such that the gatherrolls, instead of slides. along the interior of the spiral wall It o! the marverer the latter is rotated, and .(lnc to the shape of such Wall. which at each point is inclined to the direction of rotarv movement of that point of the wall. theportions thereof which are hr uc'ht successively in contact with the gather. are successively closer to the axial line of the glass-carrying spindle, (which is held stationary, except-for its rotation at. this time) the solid mass of glass forming the gather will have all portions of its circuit.lerenl'ial walls broughtinto contact. with the inner face'oflhe spiral wall 7%. whereby it will be rendered homogeneous, be given a surface chill. and will be reduccdfto a definite and predetermined size and shape. Aftcr the ma'rverer has been rotated through a predetermined a e around the axis formed by its shaft T4. the con tinued movement of the head 5 around the standard 3 will cause the lever 83 to en rage a portion of its actuating cam run whereh the. engagement of the clutch block will he shi l'ted from the gear 80 to the gear 80. resulting in a revm'sal of the direction of driving ofthe horizontal shaft. and a corresponding reversal in the direction of rolation of the i'narverer. carrying: the lat ter hack to the position illustrated in Figure 2). In this reversal of the rotation of the marverer. the spiral wall thereof will move away from the marvercd gather. so that the latter will not e.rul;ihed during the time and during this period the muti-- lated portion of the ,pinion 78* is in the line. of centers, but at the termination thereof the teeth upon the mutilated pinion again engage the beveled near 76 11 on the mar vererframe and swing. the latter upon its hor zontal pivot to restore the marverer to its initial position, after which the lever 83 "ages :1 portion of the com run 83 anti 1 .igsgcs the clutch block 82 from the gear centers it between it and the gear arresting: the rotation 01" the horiioft iii The glass carrying spindle 'ivcu, by its actuating mechanism, mews net-c i'y to swing the marvel-ed they anal to y osition the spindle between hlowin and molding mechanisms. 7 .iu the show: described complete and. highly,orgnnizcd embodiment of my invention. but will, be seen, thut my invention, in so for as it relates purely to marveling mcclnn'iisn'n cm'ooiilios in its broader aspects,
