TIMING MECHANISM.

Application filed May 29, 1924. Serial No. 716,885.

My invention consists in certain new and useful improvements in devices for timingthe operation of a group of two or more operatively associated mechanisms or. a group of associated mechanical oper'ations.

While it may be applied advantageously to the timing of grouped mechanisms and mechanical operations in many different arts, my invention has been especially designed for use in the glass fabricating art.

For instance, inrthe modern practice of the latter art, the automatic and semi-automatic fabricating machines are supplied by automatic feeders with mold charges, or gobs of molten glass, and the proper and accurate timing of the various mechanical operations involved is of the highest importance. Moreover it is important that this timing be adjustable, and 'that all or certain of such adjustments may be made while the mechanisms are in full operation.

Again, the moving parts of mechanisms operated at high speed require adequate lubrication, and suchlubrication must 'be properly timed with the'speed of the mov ing parts, and as such speed is increased or decreased the application of the lubrication must be adjusted to obtain the necessary lead, so that the lubricant and the travelling part to be lubricated will form the proper conjunction. t

For these general purposes I have invented a new and improved timing mechanism which makes possible the practical and accurate timing of the operations of a group of associated mechanisms, and which also rovides for the adjustment of the timing of lndividual mechanisms, or of two or more of the same, relative to the remainder of the group, without halting or interfering with the normal and continuous operations of the mechanisms. I also provide adjustable timing means for the intermittent lubrication of the moving parts of one or more of the mechanisms.

Again, in the case of a group of mechanisms associated in timed relation, it is frequently important to advance or retard the operation-0f one or more members ofsthe group, or of one or more of a group of mechanical operations, relative to the. operations of another 'or others of the group.

Thus, where an automatic or semi-automatic glass fabricating machine is fed-by an automatic feeder, as the speed of the machine is increased, the instant of dropplug the gobs into the molds must be advanced relative to the position of the molds relative to the feeder orifice as they are in turn brought into feeding relation with said orifice so that the gob and the mold cavity Will arrive at the proper point simultaneously. Likewise the instants of intermittently supplying lubricant to moving parts of the machine should'be advanced. Vice versa a slowing down of the speed of the made while the machine is in continuous operation.

In glass fabricating machines a funnel or other guide is frequently employed to direct the gobor mold charge from the orifice of the feeder to the mold. In cases where the gobs are delivered to moving molds the mannerof delivery must be varied in ac cordance with the speed of the molds travel. Thus'a funnel or guide having its axis of delivery vertically disposed, while proper for feeding gobs to a stationary or slow moving mold, would be unsatisfactory in the case of a rapidly moving mold, since the descending 'gob would strike the wall of the mold and thus be irregularly chilled and distorted. As the speed of mold travel is increased, the axis of delivery of the funnel or guide must tilted, its lower end moving in the direction of the molds travel, so that the gob will fall true into the mold without striking the walls thereof. I therefore provide a new and improved funnelguide device which maybe adjusted to meet the requirements of various mold speeds.

Other novel features of construction and also of. arrangement of parts will appear from the following description.

A. The casing F has a For the purpose of clearly disclosing the principles of my present invention I have shown the same embodied in a timin device of the rotary type, but itwill be un erstood that many of the characteristic features of my invention may likewise be applied to timing devices operated by other than rotar movement.

n the accompanying drawings, Fig. 1 is a diagrammatic view a timer, embodying the rinciples of my present invention, ap, plied to a rotary glass fabricating machine receiving its mold charges from an automatic feeder of the plunger type, the opera tion of the feeder and of the lubricating device being timed fromthe operation of the fabricating machine; Fig. 2 is an enlarged vertical section of the timing device proper; Fig. 3 is a reduced plan view of the same; Fig. 4 is an enlarged detail in section showing one of the cam rings, its supporting disk and the mechanism for adjusting the cam ring on the disk; Fig. 5 is a broken plan view showing one of the disks on which the cam rings are supported; Fig. 6 is a re,- duced diametric section of one of the cam rings, also showing a modified form of roller mountin Fig. 6 is a detail also showing such modified mounting; Fig. 7 ,is a broken view in detail showing the means for adjusting the ad'ustable valve stand; Fig. 8 1s a sectional view showing one of the timed lubricating valves; Fig. 9 is a similar view of one of the lubricant discharge nozzles; Fig. 10 is an illustrative view showing the manner of using the latter, and Fi 11 is a detail of the mounting of the ad]ustable funnel guide.

The following is a detailed description of the drawings.

A represents a stationary part of a glass fabricating machine, such as the central gedestal or support on which the mold table is rotatably mounted. C represents one of an annular series of molds mounted on said table concentrically therewith and brought in turn by the rotation of the table in feeding relation to the discharge orifice 1 of the automatic feeder D, which latter is shown as of the reciprocating lunger type.

E represents a variable speed electric motor carried on the support A and havin its shaft provided with a "pinion 2 mes in with a gear 3 on the outer end of a sha 4 which is journaled in bearings in the side 'wall of the circular casing F. The casing F is fixedly supported in place as b means of the bracket 5 extending from t e support permanent bottom 6 and a removable lid 7.

G is a verticall disposed shaft which is journaled in the s eeve bearing 8 of the bottom 6 of the casing F and the bearing 8 in the lower end of a sleeve 9 which depends axially from the casing F. 10 is a beveled gear fixed on the shaft G within the casing and having its hub 10 supported by the anti-friction thrust bearing 11 which also serves to support the shaft G at proper elevation. The inner end of the shaft 4 carries a pinion 12 which is in mesh with the gear 10.

In the fabricating machine illustrated, the mold table is of constantly rotating t pe, and is shown driven directly from the s aft G by means of a inion 13 on the lower end of said shaft mes ed with an annular gear 14 which forms part of and is concentric of the mold table. Thus the molds are presented in turn to the feeder by the rotation of the table. By speeding up or slowin down the motor the speed of operation 0 the glass fabricating machine may be adjusted to suit the purposes in view.

H represents a sleeve fixed on the upper end of the shaft G and which has its lower end journaled in a bearing 15 in the lid 7 of the casing F. The gear 10 and the sleeve H may be keyed to the shaft G, as by means of the longitudinal fin 10* of the shaft en aging notches in the ear and sleeve. A s ort distance above the id 7 the sleeve H is provided with a shoulder 16 upon which rests an annular bottom plate I which is sli ped down on the sleeve H.

being generally indicated by the letter J,

the bottom disk J being supported by its hub on the bottom plate I, while the remaining disks J, J, J, JflJ, J and J are supported in su erimposed relation by their hubs. Each 0 the disks supports a cam ring, said rings being indicated at K K K, K, K", K, K and K Said rings are of differenial bore, their lower and larger gears 19. The letter M represents pinions,

each of said pinions being in mesh with the internal gears 19 of a cam ring K. Each of said pinions is fixed on the lower end of a shaft N, which shafts extend down through sets of alined holes 20 in the cover plate L in the disks J positioned above the cam ring with which its associate pinion is meshed. Said shafts are spaced apart in annular series concentric with the sleeve H. Each disk J is provided with a sunken seat 21 axially alined with the associated shaft N, and in said seats are seated and fixed, as

A stack of dis (s is slipped down over the sleeve H, said disks lon bores fitting down over the corresponding llU by the pins 22, the internal gear or look- .ing gears 23 with which the lower ortions of the pinions M may be mes ed by lowering the corresponding shafts N until the pinion seats within the locking gear. It is evident that when a pinion M is meshed with the corresponding looking gear 23 and also with the internal gear 19 of the corresponding cam ring K, said cam ring is locked ag inst rotary movement relative to its dis It is also evident that by raising the shaft, its pinion may be drawn up out of mesh with the lock ing gear 23 while remaining in mesh with the internal gear 19 of the cam ring, thus unlocking the cam ring and permitting its adjustment relative to its disk, which adjustment 'isaccomplished by rotating the associated shaft, and. thus turning the ring on its disk. When the proper adjustment has been made, the inion M is again dropped down into mes with the fixed locking gear 23, thus once more locking the associated cam ring fixedly to its disk. The upper ends of the shafts'N are provided wlth knobs 24, which may be grasped to raise a shaft to unlock its associated cam ring, to rotate the shaft for adjusting the cam ring on its disk, and to drop the shaft to relock the adjusted cam ring to its disk. I

For convenience in determining the proper ad'ustment, said knobs-are provided with num ers or other distinguishing symbols on their tops, while similar numbers or 1 symbols are placed on the outer perimeters of the corresponding cam rings. L Thus in Fig. 1 the cam rings are numbered upwardly from I to VIII in Roman numerals, and in Fig. 3 the corresponding knobs 24 are similarly numbered so that an operator will know that by manipulatin one of said knobs he may unlock, adjust an relock the cam ring which is similarly-minibered. If preferred the perimeters .of the. cam rings may be painted 'in contrasting colors, and the corresponding knobs, valves, connecting pipes, etc. similarly colored, so that the operator may tell at a glance what knob to operate for the adjustment of the actuation of any particular control member.

The knobs 24 are provided-with flared. annular skirts 25 which are rovidedwith a circumferential series 0 graduations which may be numbered with Roman numerals or otherwise distinguished so that the operator may quickly and accurately adjust a cam ring to a predetermined relation, as, for instance, that shown on a chart. To further assist in this adjustment, the cover plate L is provided witha beveled edge. 26 which opposite each ofthe shaft positions is marked with an arrow head or other indicator 27 in relation to which the graduations on the knob may be, adjusted, as required to obtain the desiredadjustment of the corresponding cam ring. Each of said arrow heads or other markers is associated with the same number or symbol marked on the surface 26 as that'on the knob of the corresponding shaft. This assists in the rapid assembla e of the timer, and also the adjustment 0% parts.

When the timer is to be adjusted for use for timing a given group of mechanisms to obtain certain predetermined results the operator is provided with a. chart indicating how the cam rings are to be adjusted, and the operator by consulting his chart can tell into what position each particular cam ring is to be turned.

The top of the timer is free from all obstacles or projections, except the knobs 24, and it is practical for an operator to. grasp the knob, raise it and turn it in either direction to adjust the corresponding cam ring, while the timer is in motion. This is a very important feature, as it makes practical the adjustment of the individual cam rings while the mechanisms are in operation, and therefore makes possible and convenient a degree of nicety and accuracy in adjustment which would be impossible were it necessary to stop the operation of the timer.

The cam rings are provided with per-.

imetral striking or contact means which, as the. rings revolve, intermittently actuate valves or other control elements mounted in their paths.

' In the case of all of the cam rings K, except the two upper rin s K and K the actuation is momentary. n the case of the two upper rings the actuation is more prolonged.

Thus the cam rings are provided with radially projecting brackets 28 provided at their outer ends with upwardly extending pins 29 upon which are rotatably mounted the contact rollers 30.

In the case of the upper rings K and K, the rollers 30 are omitted, and arcuate cam plates 31 and 32 are substituted. Such plates have their inner perimetral edges curved to fit snugly against the perimeter of the cam ring while their outer and concentric perimetral edges form the contact surfaces which actuate the associated valves or other elements.- The plates are held in place by the pins 2Q which extends up through holes in the arcuate plates. By providing two plates for each bracket and providing each plate with a plurality of pin holes, the effective actuating length of the cam may be adjusted by shifting tlfe plates relative to each other'on the pin.

In Figs. 6 and 6 I show amodified form of mounting the rollers 30 on the cam rings K. Thus instead of the integral or fixed its actuating Ill bracket 28 shown in Fig. 1,theroller 'brack- 3 entially of the caln ring to adjust the position of the roller relative thereto. At one point the slot is fully open, as shown at 28 in Fig. 6, so that the bracket may be detached from the cam ring by moving it to the open portion of the slot. The bracket may be fixed in any adjusted position by means ot'the set screws 28 which engage threaded holes in the bracket base and may be screwed in against the cam ring, thus jamming the bracket base against the frontwalls of the slot.

lVhere momentary actuation is required, as in the case of a rotary valve controlling the admission of fluid pressure to a doubleacting cylinder, I prefer to use the roller 30. but where a relatively prolonged actuation is desired, as in the case of springclosed, plunger valves controlling the application of lubricant to moving parts, I may use a cam plate; and where the period of actuation is to he adjustable, I use a pair of cam plates so that the effective length of the actuating edge may be varied.

The modified form 28 of bracket shown in Figs. 6 and 6 may be used in connection with the cam plate or plates, thus making them adjustable relative to the cam rings.

In the embodiment shown in the drawings, I have shown the actuated elements,

which control the operations of the associated mechanisms or mechanical operations as valves, some being of the rotary type and others of the spring-closed, plunger types. It is of course apparent to those skilled in the art that various types of valves or other control devices may be used.

The valves or other control devices may be fixed in relation to the cam rings; or may be adjustable in relation thereto, preferably while the timer is in normal operation.

Thus O is a vertically disposed valve stand secured at one side of the timer on a base 33 which may be integral with the lid 7 of the casing F, the stand 0 being fixed in position relative to the timer.

Again, the other side of the timer is a second vertically disposed valve stand P which is adjustable in its position relative to the timer. so as to advance or retard the actuation of its valves relative to the actuation of the valves on stand 0. Thus, as shown in Figs. 1 and 7, the base of said stand is an inwardly extending horizontal leg 34 ending in an annulus or hub 35 which fits over a circular boss 36 on the lid 7 concentric with the bearing 15. 36 is a holder ring bolted down on said base above and overlapping said annulus 35 to hold it slidably in place. It is thus seen that the stand valves Q and Q. The valve Q is connected by the pipes 37 and 38 to the upper and lower ends of the cylinder 39 of the feeder plunger R, while the valve Q is connected by the pipes 40 and 41 to the front and rear ends of the cylinder 42 which operates the shear blades of the feeder D. The valves are shown with rotary operative stems 43 provided with pairs of opposed cam wings 44 and 45 which are in the paths of the rollers 30 of the adjacent cam rings of the timer. Thus, the valve Q is operated in one direction by the cam rollers 30 of the cam ring V and is operated in the opposite direction by the rollers 30 of the cam ring VI. Likewise, the valve Q is operated in one direction by the roller 30 of the cam ring I and in the otherdirection by the roller 30 of the cam ring II. It is thus evident that with the valve stand P fixed against movement in the position desired. the cam rings V, VI. I and II may be adjusted so that. their rollers 30 will actuate the valves Q and Q in such manner that the plunger R will be reciprocated and the shears S will be opened and closed in the proper timed relation with the rotation of the mold table B to properly deliver the gobs of the proper character to the molds C as they are in turn brought into feeding relation with the orific'e 1 by the rotation of the table.

The position of the valve stand P relative to the timer may be adjusted by means of a horizontally disposed worm 46 journaled in the stand 47 mounted on the lid 7 and meshing with a small rack 48 fixed to the valve stand P. 49 is a crank handle by means of which the worm 46 may be turned to swing the valve stand P either clockwise or counterclockwise relative to the timer. When idle, the worm 46' acts as a lock to hold the stand P stationary.

When the mold table is rotating at a relatively slow speed, it is necessary, to insure the dropping of the gobs at the proper instant into the molds, to retard the action of the-feeder relative to the approach of the molds to feeding relation. and therefore in such case the valve stand P is shifted into such position relative to the timer that the actuation of the plunger and shear control valves is retarded. As the speed of the machine is increased it is necessary to advance the operation of the feeder so that the gobs may be properly deposited in conjunction with the -rapidly moving molds In such case the valve stand P is moved for the proper distance in the opposite direction to advance the operation of the feeder.

I show mounted on the valve stand 0 a rotary valve Q? which may be connected to valve casing. When the cam the fiuid pressure cylinder which operates relation to the speed of the mold table, while the operation of the plunger for the gob delivery function may be adjusted in relation to the speed of mold travel.

represents a compressed air supply line connected to each of the valves Q and Q, and Q, and said valves are also provided with the usual relief ports to atmosphere, so that when the valve is turned in one direction'fluid pressure is admitted to one end of its associate cylinder and relieved from the other end thereof, and when the valve is thrown to the other position the fluid pressure is admitted to the second named end of the cylinder andrelieved from the first named end thereof. I

U and U represent a pair of lubricant control valves which are mounted on the stand 0 and are actuated by the cam plates 31 and 32 of the cam rings K and K. The construction of the form of valve preferredis shown in Fig. 8. Thus, the rear end of the valve is provided with a port 51 which is connected by the branched pipe 52 with a reservoir W in which is maintained a supply of lubricating oil under delivery pressure. At the other end of the valve chamber a lateral port 53 is connected to the branched pipe 54 for the delivery of the oil to the moving parts which are'to be lubricated. Intermediate got the ports 51 and 53 is a valve seat 55 normally closed by the. spring seated valve 56. The stem of the valve 56 protrudes through the front of the valve casing against which bears the adjustable contact knob 57 carried on the end of the swinging arm 58 pivoted to the plates of the camrings K and K come in turn into contact with the knobs 57 the valves are opened and held 0 en until the plates are moved pastthe kno s, whereupon the valves automatically close. It is evident that the opening of the valves U and U in turn, results in oil under pressure being ejected along the pipe 54. The pipe 54 isbranched and leads to various portions of the mechanisms which require intermittent lubrication. In Fig. 9 'I show a nozzle X for ejecting t e oil at the pipe ends, the discharge passage being cone shape and adjustab e by means of thescrew mounted cap 59, so that the nozzle may be adjusted to either squirt or spray the oil. Thus one of the branches of the pipe 54 ends adjacent to the shear blades S in their closed position and is provided with a nozzle X? which is adjuste Ipreferred form for ejecting a thin.

spray of oil upon the blades as they close. Another end of said pipe 54 depends above the path of the hinge pins 59 of the molds C as they in turn pass the feed position and is provided with a nozzle X for thedischarge ofoil upon the mold hinges as they pass. In such case the cap of the nozzle X is adjusted to provide for a more copious discharge than in the. case of the nozzle lubricating the shear blades.

Another end ofthe pipe 54 is shown adja cent to one of the cam ring rollers 30 so that its nozzle X will discharge oil on the roller as it asses.

It is evi ent that these pipe ends may be positioned wherever needed and the control valves timed to discharge the oil as the moving part, which is to be lubricated, passes the nozzle. The pipe 54 may be extended to furnish a supply of oil to parts in continuous moving contact. Thus at 60 I show a branch of said pipe connected to a port 61 in the stationary valve cap member Y with which the ported portion Y of the mold table is in sliding contact.

Again, for the purpose of illustrating other methods of controlled lubrication, the branched pipe 52 is shown connected to a sprlng closed, plunger valve U mounted on a bracket 62 extending from thesleeve 9, said plunger valve being opened at intervals by the rollers 63 carried by the hinge lug of the molds C, so as each mold passes the valve U a quantityv of oil is squirted m through the outlet pipe 64 on some moving part requiring lubrication. The pipe 64 is preferably flexible, such as a copper tube, so that it may be bent to correctly deposit or direct the discharge of lubricant.

A branch 64 of the pipev64 may be properly directed to discharge oil on the mold hinges, the pipes 64 and 64 being provided with valves to shut off the discharge from either or both, and the pipe 64 -being provided with a nozzle X. At 64 I show a discharge tube connected to the pipe 52 for the constant discharge of oil to a bearing or other mechanism requiring a continuous supply of oil.

I have shown the lubricant control valves U and U mounted on the fixed mold stand 0, so that their operation will be timed with However,

position of the moving .part to ,be lubricated. I may therefor mount certain of the lubri cant control valves on the adjustable ptand P, so thatsuch lubrication may be advanced or retarded, as in the case of the operative movement of the feeder lunger and shears, to compensate for di erent mold table speeds.

The oil i s 52 and 54 and their branches are proviciiz with shut-off cocks at suitable points so that the lubricant may be shut ofl from individual nozzles X as'found necessary.

In Fig. 10 I have indicated an enclosed moving part into which the oil nozzle X is shown squirting lubricant at the proper moment of con'unction.

Where two a jacent cam rings are used to actuate a double actin valve, such as the rotary valves Q, Q, an Q, in opposite directions, unlesssome means were provided to prevent a careless adjustment of the rings bringing their actuating members into such close proximity as to actuate the valve simultaneously or almost. simultaneously in opposite directions, the proper operation of t e valve would be interfered with and breakage might ensue.

To prevent such careless adjustment, I provide suitable means to limit the proxim- 1t of the actuating rollers of adjacent rings. T us the bracket 28 of the lower of the air of rings is provided with an upstan ing pin 66 which extends into the path of the racket 28 of the cam ring next above and therefore limits the adjustment of the upper cam ring so that the two rollers 30 can not be brought into such proximity as to improperly actuate the valve.

At Z in Fig. l I show the funnel-guide which directs the gob of glass or mold charge 67 into the mold G which is traveling through the feedin position. Where the mold table is trave lng at a relatively low speed, the axis of the throat of the funnel Z may be vertically dis osed, as shown, but

as the speed of the mo (1 table is increased,

it is necessary to drop the ob more quickly and in such a manner that it will not hit .on the side of the mold cavity but dro truly thereinto. Thus, I mount the funne Z under the orifice l in such a manner that its axis may be tilted from the vertical into a position. with its lower end advanced in the direction of the movement of the mold. The higher the s eed of the molds travel, to greater must e such inclination. The mounting of the funnel is shown in detail in Fig. 11.

Thus, 68 is a bracket bolted or otherwise attached to the under side of the feeder frame and having its free end underlying the orifice 1 and the shears S. The free end of the bracket is provided with a semicircular yoke 69 facing in the direction of the travel of the molds. 70 is an annular funnel holder mounted in the yoke 69 by means of its diametrically opposed trunnions 71 which are alined 1n a plane radial of the axis of the rotation of the mold table. The funnel Z fits down in the holder 70 and is supported therein by its circumferential shoulder 72. The holder is provided below its axis of rotation with a projection 73 parallel with and in front 0 the bracket 68, and 74 is a set screw screwed through a threaded hole in said projection and impinglilng against the front of the bracket 68.

f t e set screw be retracted, the influence of gravity will cause the funnel to assume a vertical position, but by screwing in the set screw against the" bracket any desired inclination of the axis ofvthe funnels throat may be obtained to enable the gobs to be delivered properly to the molds traveling at any practical speed. To permit the funnel to be raised or lowered to accommodate molds of different heights, I may interpose one-or more shims or spacers 68 between the bracket 68- and-the feeder frame, as shown in Fig. 1.
