'The rotation of the spindle is 'thereby produced "ill'ie caro. 80 furthermore, and as already explained, actnates the pawl 82 to move the spindle axially forward and backward The cow/5er.
The carrierf110 comprises an .1 -shaped Wedge block or cam 90 which is rotatively mounted in the horizontal arm of the support, a clutch mechanism for gripping the interior Walls of' a tumbler, and a guide 113, y
` Afiixed to the vertical shaft 112' and below the bearing, provided by the support, is a ratchet wheel 11st, (see Fig. 7)' which is adapted to be engaged by a spring-pressed pavvl 115. A pawl carrier 116 is rotatively mounted on the shaft 112 adjacent to the ratchet Wheel and has an odset projection 117 in which the pa-Wl is supported. The carrier 116 has a laterally projecting-arm 118 which is advanced between a pair of limiting stops 119 during each rotative movement of the support about the spindle as an axis, the head stock being provided Witli a stationary projection 120 having a cam surface 121.
Directly above the bearing of the vertical shaft 112 is a notched disk or Wheel 122 which is engaged by a paw/l 128 to determine each of the cutting positions of the glass. The pawl is pressed into engagement with the notched periphery of the. disk by a spring and is released from the disk in opposition to tbe torce of the spring by the cam surface 125 of a projection 126. The pawl is also tripped once for each rotation of the support about the spindle as an axis.A Above the disk 122ivhich is removable and may be replaced by disks liaving different arrangements of notches, is the clamping mechanism which is capable of being eX- panded to firmly grip tlie interior-Walls of sections together. The section 127a has a hollow boss 130 through which a resilient key 131 extends so as to engage one of a series of recesses or depressions 132 in .tlie vertical shaft 112. By this meansthe seo tion 12Ta is removably secured' to tbe shaftA and the liub section 127 thereon;
The shaft 112 is hollow and a. rod 133 extends tliroagli it. The rod near its upper end is provided with a .transverse pin 1314 sliaft and is aiited to tbe 'hub 127, The slot is of suliicient length topermit a limited isa-mounted to slide' axial movement of the hub on thejshanft;A
Secured to tbe sliai't 112 near its upper en'd is 'a circnlar clamping plate 136 which is preferably provided with al gasket or Washer 137 of rubber' or other yieldi'ne material,l il. helical spring 138 surroundsl thev upper end; ofthe shaft 112, being'interposed 'which extends through a slot 135 inthe between the clamping plate 136 and the body ot the. hub 127. 1t therefore tends to press the hub sections 12T-12Ta together. The hub section 127a .is provided Vwith a flange 139 to which are loosely attached a plurality of sectors 140 which have conically curved inner surfaces to cooperate with the truste-conical outer surface of the body of the hub 127. IThe arrangement of parts is such that the sectors 140 are pressed outwardly by the action of the springs 129 and the spring 138. Their outer surfaces are curved to conform to the interior surface of a tumbler or other article to be cut.
he springs 129 are relatively light and consequently it is only necessary to press upwardly on the rod 133 in order to separate the hub sections 12?*1271 sectors or wedge blocks 140.
In order to still further insure that a tumbler cannot accidentally be removed from the carrier, a bloclr let-1 which is pivotally secured to the guide arm 113 is pressed against the bottom of the tumbler by means ot a spring M2, the arm being pivotally mounted at 1li-3 near the upper end oi the L-shaped support 111.
Before describing` the moditied structure shown in Fig. 8 or discussing the designs illustrated forth the opeiation of the machine. Assuming that the carrier occupils the position substantially as shown in Fig. #l otl the drawings,cxcept that no tumbler or glass article is in place, a rod 111- which may be comic-gtn ed with av loot press orothersnitable device, is for ed upwardly to engave the lower crd of the rod 13B. As already explained` when this rod is forced upwardly relative vto the shaft 112, the clamping` mechanisn'i is released hy the separation ot the hub sections lift-1278; lt, now, the guide arm 113 is swung out of the way on its pi vot 1&3, the tumbler m L e forced downwardly onto the carrier until the disk 136 is pressed closely into it. The rod 133 will then be released and thereupon the springs 138 and 129, draw the hub sections together and force the sectors 140 in position to clamp the interior surface of the tumbler. The guide arm 113 is then placed in position as shown in Fig. so that the spring 2 draws they pressure block 1411 against the bottom ot' the tumbler.
The grinding process may now .be commenced by starting; the rotation ot the driving shaft (il. This rotative movement is transmitted through the fears tSIi and (il to the cam 58 and the cam 'lhe rotation of the cani so acts upon the roller Sl ol the pawl S2 as to permit aspx-ing' l-lB to force lthe spindle l5. together with the carrier and tumbler toward the grinding nina-l 25, whichot' course is rotating at Ya high rate of speed. The glass' is l'orled against. the wheel.l a single cut, such as one oli those and release the in Figs. 9, 10 and 11, l will setk shown in Fig. 9, being produced in the glass'. 'lhe progress of thev spindle is haltet when the eut reaches a predetermined depth by the engagement of the glass with the lingers ot the bell crank lever 24C and the consequent rocking o the bell crank lever. A slight movement of the fingers produces a material upward movement of the rod 95. llhis upward movement, as already eX- plained, moves the wedge block 99 out wardly in the guideways 100 and into the path of the projections 49 of the. disk 47. Thewedge block cooperating with these projections tol-ees the spindle backwardly in opposition to the spring 115. The spindle free to more in this direction and to carry the pawl Si) with it since only the spring 115 is depended upon for moving the spindle forward and the roller 81 is not I )ositivcly held in engagement with the surface of the cam S0. The tension ot' the spring 115 is such as to give the proper cutting speed.
The lurther rotation ot' the cam 80 brings the projection 10Sl into contact with one arm of the. bell crank lever and produces the rocking movement ot this lever in opposition to the spring 109. By this means the pawl 10G advances the ratchet wheel 101 through one notch, the 4gear wheel 10-5 and the gear wheel 102 being turned a corresponding amount. ln consequence ot' this movement. of the `gear wheel 102 the spindle and the carrier 110 are rotated through u predetermined arc, swingA `ing thel tumbler into a position such as that shown in Fig. 0. tor example. @t course the inclination of the tumbler at each. position may be varied and determined by the number of teeth on the ratchet theel 101. The continuing' rotation of th" 50 produces alternately a cut'and a` re'. tionarv movement ot the tumbler about the center el the spindle 45 as an axis. 'When one revolution of. the tumbler and carrier is thus completed7 a series of cuts will have been lormed radiating from a single center as. tor example. the four cuts 146 shown in Fig. 11. Just at the end of a. complete revoA lution of the spindle the pawl 123 released by reason of its engagement with the cani surface 125 and immediately thereafter the pawl carrier 11G is advanced by the engagement of its projection 118 with the cani surface 121. This advancement of the carrier iroduces a rotative move nient ot' the shatt 112 and of the tumbler about the shaft as an axis. rthis moves the tumbler to the next position and depends upon the notches ot the dish 122.
For each complete revolution of the support 1117 in addition to the foregoing. the ratchet 7? is toi-ccd outwardly producing a movement of the carrier 74 and advance ment et' the ratchet wheel 7;. By this means Leanne Therefore the pin ep f op or the several movements of the carrier die l5 as an axis until finally, 'oler completely rotated on g heen revolved at eaeli step,
the pini es the arm 6T into position The completed tumbler may new be re- 'i iii-,owed and replaced by another and the maenine started and operated as before.
face of 'the grii'iding wheel must o oe main* ined in proper form and Jn and for this purpose have proie facing tool 50. riliis tool may be d to face the tool by turning the nandle and the shaft 17. When this snaltt i: 'turned the. tool 3G as a Whole, is edif'aneed reason oi the'fact that the joost Si has downwardly extending pro- ;Eeetion 2312* which is tapped vto receive one of the screw-threaded portions of the shaft. The turning; the shaft also serves to advance, b equal amount in an opposite i rcetion, both the head stoel: and the only the head stock being provided. i a projection 4G and the block being in'ovided with a projection 231 which proj JLions are tapped and engage the oppo- Silely screw-threaded portion of the shaft as clearly shown in Fig.
As already pointed out, the parts 30, and 40 are mounted in guideways and the oase plate .l5 is provided with suitable slots through which 'the projections 31E, 23 and #10 extend.
The pitch o the, 'threads in each of the sferen/threaded sections of the shaft l? correspond, although one has right hand and the other left hand threads. it is therei'ore evident that when the surfacing tool is advanced to some extent to reduce the size 2' the grinding wheel, bvi'aeina' its surface,
. stop ad aneed by a like amount toward the center oi? the Wheel,-in other Words, the relative positi n of the wheelsuri'ace and of the e `nell crank 2li and the head stock,- ogether stili the tumbler and carrier, are
dilierent cuts made at each or the rotativo positions of `he tumbler, a revolutionary movement of the tumbler being effected for each group. This is not essential to my invention and 'the number of cuts radiating from a single. center may oe varied as de-y sired, as already pointed out.
A group of four sets cuts is shown in Fig. l0 while in liig. 9 there are two diff ferent superposed groups of sets, each group Jcorresgending to those of Figs. l0 and il except that adjacent sets in the same group are spaced so that they lo `not overlap.
ln ease it is found desirable to operate the machine at its yhighest speed, this may be accomplished by providing a slightly modi fied cam 150 as shown in Fig. fi, in order that the cuttingr stroke of the machine may be maintained at the same speed while the driving speed may be increased. The eut-` ting speed is, of course, limited hy tlieolnaractor of llie grinding Wheel and the safe operation of the device.
Attention is-particularly directed lo the fact that the depth of the out is autoniati cally determined by, and furthermore is regulated relative to, the surface of the glass adjacent to the eut.. rlhie several cuts may therefore have e. very uniform appearance and also compensation is made for the variations and irregularities in the thickness and contour of the glass.
ltis evident that various structural modi fic-ations' maj.y he eiected Within the spirit and scope ot' my invention, and l intend that only such limitations be imposed as ureiw dieated in the appended claims.
