MOLDING-MACHINE.

Application filed July 25, 1913.

To all whom it may concern Be it known that I, JOHN E. REIeNnR, a citizen of the United'States, residing in Pottstown, county of Montgomery, State.

of Pennsylvania, have invented certain Improvements in Molding-Machines, of which the following is a specification.

One object of my invention is to construct a molding machine so that both parts of the mold can be made at the same time and by the same operation.

A further object of. the invention is to construct the machine in a simple yet substantial manner so'that one man can readily operate it and can handle both sections of the flasks.

In the accompanying drawings: Figure 1 is a front view of my improved molding machine; Fig. 2 is a side view showing the parts in the same positionas in Fig. 1; Fig. 3 is a sectional plan view on the line aa, Fig. 2; Figs. 41 and 5 are views in side elevation showing the parts in different positions; Figs. 6 to 9, inclusive, are front views showing the parts in different positions; Fig. 10 is a View illustrating a modification of the invention; and Fig. 11, is a perspective view illustrating the supplemental carrier.

Referring to the drawings, 1 is the base on which is a standard 2 having a bearing 3 at its upper end for the trunnion 4 of the frame 5. This frame has an arm 6 and another arm 7 and is so arranged that it can be turned in the bearing 3.

8 is a treadle pivoted at 9 and connected by a rod 10 to a latch 11 which is pivoted at 12 on the standard. This latch is adapted to enter notches in the trunnion 4: so that on depressing the treadle 8 the latch 11 is withdrawn from a notch of the trunnion and the frame can be turned, as desired. On the end of the arm 6 is a bearing 13 in which is mounted a spindle 14 having a head 15 forming a table having a flange 16 at each side. Mounted on the table is the pattern board 17 on which the sections of the flask are mounted. There is one pattern board at each side of the center of the machine and each pattern board has a cross bar 18.

19, 19 are hooked bolts which engage the cross bars 18 of the pattern boards. Each bolt has a hooked sleeve 20 which engages a notched rib 21 on the table 15. By ad- Specification of Letters TPatent.

justing the thumb nut on the bolts 19 the pattern board will be securely held to the table.

In order to move the head vertically in the bearing 13, I provide a hand lever 22 pivoted at 23 to the frame 5 in the trunnion STATES PATENT OFFICE.

and connect this lever by a link 2 1 to a two-armed lever 25 pivoted at 26 to the frame 5. This lever is connected in turn by a link 27 to another two-armed lever 28 which is in turn connected by a lever 29 to the table 15 so that by raising the lever 22 in the direction of thearrow, Fig. 2, the table 15, and the pattern board 17, will be raised to any extent desired. A spring 30 is attached to one arm of the lever 25 and at the pivot point 23 to the frame 5 so asto counterbalance the sand in the mold. This mechanism is duplicated on each side of the frame 5, as illustrated in Fig. 1, thehand lever 22 being forked, as shown in said figure, to span the frame 5. The leversare'so arranged that when the hand lever 22 is raised to the position shown in Fig. 4., for

instance, the lever 25 and link 27 are in line and lock the head in the raised position.

31 isa latch pivoted to the arm 6 and arranged to enter a notch 32in the spindle 1 1 when the frame is inverted so as to hold the spindle and its table from dropping. This latch only operates when theframe is inverted and the table 15 is in the upper position. I o

33 is the cope and 34 is the drag of the mold. 'On the cope are, sockets 35 for the reception of the steady pins 36' secured to the drag. On one pattern board 17 is a pin 3 37 which enters the socket in the cope 35, and on the other pattern board is a socket 38 to receive the pin 36 of the drag.

When the sandis placed in the sections of the mold, thehand lever 22 is grasped and shaken so as to agitate the sand in the I flasks in order that it may properly pack in the mold and when sufficient sand has been introduced the bottom boards 39 are placed on the two flasks, as illustrated in Figs. 1 and 2, and the table is raised by lifting the hand lever which is locked in. the.

40 for the spindle 41 carrying'a supplemen-v tal frame 42 which can beraised and lowered for the purpose of compressmg the sand in the flasks. This supplemental frame also forms the support-for the flasks prior to their removal from the machine when the frame is inverted. Arranged to slide in the supplemental frame v42 is a carrier 44 Fig.v

Mounted onthe. linkis anrr adjustable stop block. 62. which can be a-djaiistedaon ithe: linki and held in the adjustedpositioni by the bolt 63'-which can be locate'deinf anyone of the series of holes in the link. This mechanism is duplicated on each side of the bearing40, in the present instance,'aand the hand hold '56 connects the two levers: 54 so that upon moving the lever from the position ill-ustratedim Fig. 4 to that illustrated in Fig. 5, the supplemental frame can be brought down: upon the bottom: board of the flask and the: sand therein compressed to' any degree desired, according to the positionvof the block- 62 on the links-60;.

In'order to allow the carrier to move freely, I provide'roll ers 64 Fig. 2' on the supplemental frame to support the carrier when the parts are inverted', as illustrated in Figs; 8'andn9! Referring now tothe diagrams Figs. 4to 9, inclusive, 4-is' aside view showing the r lever 22 raised with the flasks in position forthe sand tobecompressed. Fig. 5is

asimilarrview showing the compression lever 54 turned 'wi'th the supplemental frame 'presseddown upon the bottom board and compressing the sand-within the flask. Fig. 6:1is a' front' view showing the machine inverted afterthe compression has taken place and "the pattern 'boa'rdsare on top. Fig. 7 isa front View showing the compression lever 54 returned part way; to allow the supplemental frame to draw the flasks away from the pattern boards which are suspended from the inverted table. Fig. 8 is a view showing the lever 22 raised, elevating the table and the pattern boards clear of the fiasks. Fig. 9 is a view showing the carriers drawn out and the beds turning on their pivots sothat both flasks are in position clear of the table and ready to be removed from the machine.-

The operation is as follows: 'When the mechanism is in the position illustratedin Fig. 2, the particular pattern boards for the two parts of the mold are placed on the table and are secured thereto. Two flasks of the size desired are-then placed on the pattern boards, the patterns projecting into the flasks. Sand is then placed 'in the molds and rammed in the ordinary manner and the flasks can be jarred by vibrating the handle and allowing the spindle 14 to strike an abutment on the base 1. After the desired quantity of sand is introduced into thefiasks, then thebottom boards 39 are placed in position and the supplemental frame 42 is lowered on to the bottom boards by turning the handle 54 on its pivot and by forcing the handle down to its limit according to the adjustment of the blocks 62 on the links. The frame is then inverted with the supplemental frameacting as a support for the two flasks, but the inverted pattern boards are held to the table independently of the supplemental frame. Then the lever 54 is lowered carefully, as in Fig. 7 so as to draw the flasks, with the mold therein, cle'ar of thepattern boards.

In order to allow plenty ofclearance for the lateral removal of the flasks, the table 15 is elevated by the use of'the handle 22, until the latch 31 engages the spindle 14 holding the table in'the raised position. The table is held by this latch until the frame'is again turned on its pivot. Thecarriersare then'drawn out and the beds turned on their pivotsso as to bring the flasks to the front of'the machine clearof the mechanism after which they can be readily removed. The carriers are then forced in, turning the-beds on their pivots and the treadle 8 is depressed withdrawing the latch from the notch in the trunnion when the frame'5 can be turned on its pivot bringing the table 15 to the first position. The latch 31 will drop out ofengagement with the supplemental frame and the above operation can be repeated. It will be noticed'thatthe spindles 14 and 41 are splined to theirbearings'13 and 40 -respec tively= so that while they are free to slide in their bearings, they cannot turn therein.

In Fig. 10, I have illustrated a modification in which thepatternboard 65 is locked in acentralpositionand issecured'to the frame 5. Spindles 66, having pressure plates The cope and drag sections of'the mold are secured, one on each side of the pattern board, and when a flask is filled with'sand and the pressure plate is actuated so as to compress the sand in the flask, then the frame 5 is turned and the same operation is repeated with regard to the other flask, after which first one flask and then the other is detached from the pattern board andwithdrawn by actuating the pressure plate which becomes the support for the flasks.
