To all whom it my'conce'm:
Be it known that we, EnNss'r N. Onion and SWAN Swanson citizens of the United Sta-tes, residing at Muskegon, in the county of Muskegon and State of Michifran, have invented certain new and useful rimprovements in lllolding-lilachines, of which the lfollowing is a specification.
This invention involves improvements in a known type of molding machines wherein are used for urposes of general coperation a rotary tab e adapted to be intermittently operated to bring successive mold boxes or molds into operating positions beneath a vertically movable core presser, there being revisions for actuating said core presser to oroe a core into the mold. The operation of the presser is of course in timed relation to the operation of the rotary table, taking place at a period when the table is stationl'lilith the foregoing in view the present invention resides in improved operating means for the core presser, special actuating means whereb the molds are elevated as they are movedrrom operatin f position to a posltion for lifting out from t e rotary table for the removal of the molded article, tother with other novel details of construction.
In the present instance the molding machine is desi ed primarily for the making of molded rubber batteryA jars and similar articles of manufacture.
In the accompanying drawings` Figure 1 is 'a vertical sectional view of the molding table embodying the essential features of the invention;
Fig. 2 is a top plan view of the same;
Fig. 3 is a vertical sectional view showing more particularly the mechanism for intermittently o erating the rotary table and controlling t e valves by which the passage of the pressure medium to the pressure cylinder is controlled:
Fig. 4 is a. view on the line 4-4 of Fig. more clearly showing the clutch devices and two of the valve operating members;
Fi 5 isa perspective view of the spring whic eoperates with the clutch pin, and its ofstanding operating projection;
Fig. 6 is a combined view showing in perspective the elements of the mold or mold Fig. 7 is a sectional view showing the bottom portion of the pit and illustrating in an exaggerated manner the inclined surface which elevates the molds as they pass from operating position to a position for removal from the rotary table;
Fig. 8 is a sectional view of the clutch means showing more clearly the relation of the actuating projection on the bcd with respect to the spring coperating with the clutch lipin, the view being about on the line 8 8 o Fig. 1.
Fi 9 is a detail perspective view of n. detac able auxiliary frame plate for the openings in the rotary table.
Describing the invention specifically, the machine forming the preferred embodiment thereof comprises a stand A, the bed B of which sup orts at one side the rotary table C, and at t e other side carries the operating.r mechanism generally shown at D by which the table is actuated intermittently` and the valve mechanism similarly operated to control the depression of thc cores as hereinafter set forth. The table (l operates about the axis l consistin of a central trunnion. and suitable antiriction bearings 2 arc preferably used intemnediate the bed B and the table C. The table C is equipped with a suitable number of mold or mold box receiving openings 3 seen best in Fig. 2. to which the mold boxes 4 may be supplied by hand or otherwise, and similarly removed. The mold boxes 4 are seen best in Fig. 6. as comprising a removable side 5 formed with lugs 6 at its lower edge to enter openings 7 in the bottom of the mold box proper :1nd establish un interlocking connection at this point. Likewise catches 8 at oppositr` ends of the mold box are adapted to engage projections 9 at opposite ends of the removablrl side 5, in an evident manner. The mold box 4 has the Vsides and ends thereof formed with removable uppermost section la of increased thickness, thereby establishing shoulders 4" for the pur ose of controllingr the height of the ja rs. i ections of different widths may be employed to obtatin jars of different depths. Adjacent to shoulders 4" the sides and ends of the box 4 have slots 4 Athe pipe 17 andthe pipe 18, 4cuttingy therein. On. the bottom of the mold box 4 are one or more com projections 10 which taper lfromA one end` to the other. On the bottom of the mold box are mold ribs 4 which coact in the molding operation to pro duce spaced supporting ribs on the bottom oit' the molded article.
The mold boxes` are designed to be placed in the openins of the rotary table C as said table rota progressively and intermittently, the said boxes being thereby carried into position beneath a vertically movable plunger or presser 11 disposed above the table C' and the bed B to coact with a plug or core 11' in the molding operation. In ,the bed B belowthe presser 11 is formed a pit 121into which the mold box passes as the table C rotates, so as .to assume its operative position beneath the presser. When each mold box reaches its .operating position beneath-the premer the core which is reviously dropped into the mold box upon o lastie materiel is caused m move' downwar yinio the same by the operation of the piston 12'L in the c lincler 13 which is supported by a standar 14 extendin upwardly from the bed of the stand A. gl'hc piston 12 is con` nected by a piston rod 15 with the core presser 11 and fluid pressure-pipes 16 and 17 lead to the portions of the cylinder 13 above and below r ectively, the piston 129. The pipes 16 and 1 are in communicationwith a supply pipe ldleading to a reservoir containing any `suitable pressure medium such -as water, oil, air, or the like. At the union 19 which connects the pipes 16, 17 and 18 is a control valve .of any suitable type operable by a valve lever 20 which in one position causes communication between the pipe 18 and the pipel, and in another position establishes communication between oli' the Acommunication between the pipes 1 and 18 and vice versa.
The means to operate the velvedevice including the lever 20 comprises a pair of pendant kicker bars or actuating members 21 and Q, arranged in 4proper relation to op eratn cams which comprise notched portions provided in grooves 24 of a. main vulve operating member 25. The operating member 25 consists 4of a constantly Adriven approximately circular element mounted on e drive shaft 26 operated in any suitable manner by a fixui pulley -27 :adjacent to the loose pulley 28. The shaft 261s driven constantly during the use of the machine and the notches 23 are located approximately 120 degrees apart in relation to the periphery of the grooves 24 so that during each revolution of the member 25, the valve 29 previously referred to is opened once and `closed once. This action of the valve results in u downward stroke of the presser 11 and an upward stroke, lowering and raising the 'same' into and out of egem.- ent ectively with the mold cori?.1g ms'p The means to operate tbe table C is. also o posite points and designated at BSB-(see 41g. Qn ge clutch xnlhuberclgchis a curve s w1 a u 1n 34 o eralnmln aA didine. opening rough lthe th clul'c mem er 32, said pm be nominally pressed by the ring 33 to entert e notches 2 of the' pluto member B1 whenever the pin 34 anrlves 'opposite saidnotche's. -The spring 33 has a sustaining lifting arm 35- odapted during the rotation of the parte -26 and 30 to engage a -pr 'ection 36 on a suit-y able bracket 8'( carried 'y the bed B, whereby the spring 33 is lifted at its free end away from the-member 30 thereby pul out on the pin. 34 to dieengege the letter rom the abrupt wall of the notch 82 with which vit may be engaged, rmittino the clutch member 30 to rotate gime-half' revolution without turning the clutch member 31, until the next succeeding notch 32 is engagedby seid clutch pin 34. l
Bearlng in mind-the -above .construction of clutch devices, and that-the Vclutch member 31 is provided with a-sleeve 31? on which is keyed or otherwise secured the gear 38, ,and
that the gear 38 is in mesh with a gear' 39 on the outside of the tbleC, it will be evidentthat the operating member 25, driven by the shaft 26 is adapted to actuate -the table C intermittently through the corresponding operation of the internal clutch member 81 and its` associated r 88,.
Fig. 0 shows an auxiliary etachable liet vplate 40 adapted to fit -in an'opening 3 of the table C fovprovide inconvenient means for :iseistingin supporting the mold' box when such box is of a size smaller than Ve one; suitable to fit into the opening-f3 itself. 'There will be times whenthe battery jars to be Vmolded by this machinewill "be of smaller Vsize than those Vsuitable to be molded by the boxes 4 which fit the openings 3, the
openings 3 to be of a size suitable for the maximum sized battery jars orarticle to be molded. The flat plates 40 may be of diierent sizes for reduced sized mold boxes.
