Fig. 3 is a vertical section of the same, taken in the plane of the line 3-—3 of Fig. '1. regulating the length of the stroke of the lead pump for pumping the exact quantity of lead to the‘ lead cup necessary to form a complete grid. 20 The shaft 5| has a rocker arm 54 securedto' one end thereof and said rocker arm has cables 55 connected to the respective slides 29 for rocking the shaft 5| on the forward movement of the respective slides 29 for operating the pumps. 25 The shaft 20 is suitably driven by a chain at received over sprocket wheel SI On the shaft 20 Fig. 4 is a detail section, taken in the plane of the line 4—4'of Fig. 2, showing the molds in open ‘position, and Fig. 5 is a detailed section of ‘the lead pumps, ‘ and about a sprocketwheel 52, extending from a taken in the plane of the line 5-5 of Fig. 1. My improved machine comprises a frame It speed change mechanism 53 which is driven by an constructed of suitable channels and angleirons ' electric motor. . , - ‘I . 30' Suitableconveyors 65 are supported below the arranged to support a central lead pot l2, which has suitable /means in conjunction therewith for ' molds on each side of the machine and are driven maintaining the lead or casting material in a by sprocket chains 66 from the speed change Slides 6‘! are arranged below the molten state. On each side of the lead pot are mechanism. 35 a pair of channel irons II and 14, having suitable molds for guiding cast grids to the conveyor. Suitable knock-out pins ‘10 are provided in the openings l5 and i6 therein. A cross shaft 20 extends across the machine and is suitably sup- - stationary mold, being connected to cross-bars ‘I l, ported in bearings 2| and has segment gears 22 > which bar's aresupported on studs 12 having springs 13 interposed between the bar and the mounted thereon and arranged to mesh with- pin ion gears ‘23, mounted on shafts 24.

It will be noted that the segment gears 22 are as the molds close, the lead cups 40 are tipped positioned at right angles to each other to permit for pouring the lead into the molds and the molds alternate movement to the respective bars 29 on remain ,in this position until the complemental each side of the machine. A suitable plurality gear segment causes rotation of the pinion gear 28 which rotation causes eccentric 25 to rotate, of lead molds 32 are arrange d between the sup thus opening the molds.

As this operation takes place on one side of the machine, a similar operation through like parts is alternately enacted on the other side of the machine. Thus it will be seen that while grids are being ‘cast on one side of the machine, they are being/ejected on the other side of the machine. I I ' While I have described the elements composing .one set of molds and their actuating parts, it will be apparent that all of the molds are similar in construction on both sides of the machine and are actuated in like manner. . Having thus fully described my invention, what I claim as new and desire to secure by Letters 15 Patent, is: '1. In a casting machine, the combination of a lead pot, a plurality of pairs of complemental ‘molds on each side of said lead pot, one part of each mold being stationary, the lotherpart of each V20 mold being mounted one; slide, a cross-shaft be low said slides, a pair of segment gears alter nately spaced on said shaft, shafts above said ?rst-named shaft, pinion gears on said shafts’ arranged to be rotated by the respective seg 25 ments, and crank arms on said second-named shafts having connection with said slides for opening'and closing said molds. 2. In a casting machine, the combination of a lead pot, a plurality ofpairs of complemental 30 molds on each side of said lead pot, one part of each mold being stationary, the other part of'each ' mold being mounted on a slide, a cross-shaft be low said slides, a pair of segment gearsalternate ly spac on said shaft, shafts above said first named s aft, pinion gears on said shafts ar ranged to be rotated by the respective setments. crank arms on said second-named shafts having , connection with said slides for opening and 0108-, ing said molds, and a lead cup pivoted above each of ‘said molds and means for tipping said cups 10 upon closing of said molds. ‘ 3. In a casting machine, the combination of a lead pot, a plurality of pairs of complemental molds on each side of said‘lead pot, one part of each mold being stationary, the other part of 15 each mold being mounted on a slide, a cross shaft below said slides, a pair of segment gears alternately spaced on said shaft, shafts above said first-named shaft, pinion gears on said shafts arranged to be rotated by the respective segments,'crank arms on said second-named shafts having connection with said slides for opening and closing said molds on the respective sides of ‘ said lead pot alternately,- a lead cup pivoted-above each of said molds, means for tipping said cups upon closing of said molds, means for releasing the castings upon opening of said, molds, and con veyors for .carrying said released castings out of said machine.
