RINGLE MOVEMENT REGULATING MECHANISM Filed March 1928 2 Sheets-Sheet till Patented Dec. 10, 1929 ROBERT F. RINGLE, OF ZELIENOPLE, PENNSYLVANIA MOVEMENT-REGULATTNG MECHANISM Application filed. March 7,
tly invention is an improvement in means for controlling the number of movements of a tluid-actuated mechanism, dependent on the regulation or" the actuating fluid. It is particularly designed in connection with a bumping machine or the like, for molding flasks, where it is desirable to impart a c elinite number oi": movements for each complete operation or in any machine to which the invention may be applied.
in the drawings showing one application of the invention:
big. 1 is a sectional view showing the application of the invention to a bumping ma chine, with the plunger and valve mechanism in primary position;
Fig. 2 is a detail View on the line Ill-Il of llio. 1;
1. 7. 3 is a plan view of Fig. 1;
F g. 4 is a sectional view ol the plunger and valve mechanism in its secondary position;
5 is a similar view in its final valve closing position; i
6 is a face view of the cam-controlling dial.
la the drawings, a bumping machine A. is provided with a supporting base Qon which is mounted a reciprocablebumping table 3 for flask agitation, of well known construction. in such mechanism it is desirable to impart to the table for each bumping operation a definite number of vibrations. y
The bumping machine is operated by a fluid-actuated motor M as an air motor to which air is supplied by a pipe 4 from a pressure supply pipe 5 through a controlling valve 6. Said valve opens and closes a valveseated port 7 for circulation through a casing 8 with which pipes {l and 5 are connected at each side of the port 7. The valve is normally pressed towards the valve seat for closin g by a spring 9 seated in a suitable socket or casing;' 10 and has a projecting stem 11 eX- ten ding; tl'irough the top of easing 8.
A trigger arm 12 is secured to pivoting pin 13 mounted in bracket l t and provided with a re-setting handle 15. The trigger arm 12 is provided at its other end with a shoulder 16 for engagement by the upper end of a trigger l7 pivoted at 18 on bracket 14 and havin a 1928.. Serial No. 259,894.
Plunger 21 is gradually advanced in cylinder casing 23 against retracting spring 2% by impulse of fluid in regulated amounts through ports 25, 26, as flow is admitted by the opening and closing of valve 27. Plaid valve is normally seated by spning 28 and opened by impulses of fluid as oil. lirom a reservoir 29 through valve-controlled port 30 conn'nunicating with port and by port 1 with the plunger cavity 32 of plunger casing 38.
Post is opened and closed by a springseated valve 34, closing the port upon up ward movement of plunger and opening; it upon downward suction movement of the plunger. The plunger 35 is connected by stem 36 with the armature 37 ot a solenoid magnet 38 the windingli old of which is energized by current from a generator 89 by conductors 40, a1.
The circuit is closed on each upward. movement ot' the table 3 by contacts 42, 4?. one oi which is on a pivoted arm at, normally opened by sprinp; ire-action and closed by a cam connected with the table, as shown in l in; l, or by other suitable means.
For the purpose oi regulating the pumping; stroke of the plunger 37 an adjustable cam 46 supports the armature at varying); heights, dc-
pendent on the cam adjustment by rotation of its supporting rod 47. Paaid rod. is carried in bearings 48 depending; from casing 33 and is provided at one end with a turning and indicating dial 49 adapted to rotate in the range oi a locking device as a set screw 50 of bracket 51. The latter is provided with an aperture 52 and indicating point for observation and indication of range indicating numerals on the dial, as shown in 6. By such means the location of the cam controls the length of stroke of plunger 35, which is retracted after opening of the circuit at each drop of the table by spring 53.
For the purpose of returning the oil to tank eration.
29 after each advance movement of plunger 21 I provide a valve 54 controlling circulation through port and the valve-seated port leadingto return conduit 56, discharging into the reservoir, as shown in Fig. 1. Valve 54 is normally seated by a spring 57 and is provided with an extended stem 58 mounted in an outer bearing 59 of the casing 33, with the end of the stem in range of trigger arm 17.
When plunger 21 advances and stem 20 disengages the trigger so as to allow valve 6 to seat and cut off the circulation, the stem 58 will be depressed backwardly by arm 17 under pressure of cam at the end of the plunger stroke, Fig. 4, releasing the oil behind the plunger and allowing spring 24 to force it back to the original position.
The construction and operation of the apparatus will be readily understood from the foregoing description. Dependent upon the position of cam 46, the stroke of plunger 35 will be longer or shorter each time the circuit is closed to the magnet 38 by movement of the table 3. The cam being set to the desired position,'to regulate the stroke of the armature and plunger 35, the amount of liquid pumped through valve 27 into the casing 23, and withdrawn from tank 29 through port 30, at each plunger operation, definitely determines the number of strokes necessary to force plunger 21 outwardly suflieiently far to disengage the trigger 12.
After the stem 20 has forced arm 19 sufiiciently far to release the trigger as in Fig. 4, the valve 6'Wlll be almost closed by its spring 9, still admitting alimited air supply through ipe 4 to the motor, slowing down-the op- Thereafter additional oil will be pumped into casing 23, the plunger then moving to its outward limit and opening valve 54 for release as in Fig. 5. At such time trigger 12 is thrown upwardly sufficiently far to bring its cam extension 60 fullyagainst the arm 17 and thrusting rod 58 inwardly to fully unseat valve 54, as in Fig. 5.
Partial or complete action of cam abutment 60 will eflfect such unseating, whereby to empty thecas'ing '23 upon reverse movement of plunger'21.
By movement of hand lever 15 the same operation maybe effected or completed, and by varying .theshape of the lever 12 or the length of the valve pin 11, the thrusting ,movement of the cam may be Varied or adjusted to the desired opening movement of j the valve.
The hand lever may also beutilized independently ofthe plunger movement by manual operation of thetrigger, to empty thecasing and effect resumption of the parts to normalposition. i The construction, design, arrangement and v proportions of the mechanism may be variously changed or modified as to location ofthe valve, circulatingports, or in other details by the skilled mechanic, but all such changes are to be understood as within the scope of the following claims.
