' Like characters of reference designate like parts in the several views.

Referring now to the drawings, the frame of the machine includes a pair of side members 20 which are held in spaced relation by a plurality of

transverse brace rods

21, 21, 21 and 21. Vertically extending channel members 22, placed so that their channels extend inwardly, are secured to the inner sides of the respective side members 20. Diagonally extending brace bars 23 are con nected at their lower ends to the respective side members 20 and at their upper ends to plates 24 attached to the upper ends of the respective channel members 22. The side members 20 are provided with feet 25, see Fig. 3. each of which is formed with a plurality of apertures 26 adapted to receive the respective ends of the brace rods whereby the height of the side members may be varied.

The bottom platen 27 is pivotally connected 'at its inner end to the outer ends of a pair of L-shaped links 28, see Fig. 9, the other ends of said links being pivoted on a transversely extending rod 29, see also Fig. 8. The extremities of the rod 29 carry rollers 30 which operate in the vertically extending uideways provided in the respective channel members 22. The outer end of the bottom platen 27 rests upon the upper ends of a pair of arms 31 which are fixed at their lower ends to a tubular rock shaft 32 mounted on the transverse tie-rod 21. A metal pot- 33 normally rests on the top of an upstanding support 34 carried by the fram The metal pot is provided with a pair of arms 35, the extremities of which are pivoted to the respective plates 24 and brace bars 23. The top platen 36 is con-, nected at its inner end to the outer ends of a pair of plates 37 see Fig. 9, the inner ends of said plates being pivoted on the rod 29. The connection of the two platens with the rod 29 is such that the top platen may be swung from a horizontal position on top of the bottom platen 27 through an arc of substantially 180 onto the metal pot 33, the metal pot serving to support the top platen when it is in the position shown in Fig. 1.

A pair of double-acting springs 38,.se Fig. 8, are preferably coiled about the rod 29. One end of each springis anchored in the adjacent link 28 and the other end thereof is anchored in the platen 36. WVhen said springs are free of the links and platen aforesaid, the extending end portions of each spring stand preferably in the same plane as showrrin Fig. 11. The springs normally hold the platen 36 in a substantially vertical position, assuming it is not secured in some other position. When the platen 36 is moved from its said vertical position down onto the bottom platen or onto the metal pot, it is against the action of the springs and the springs, there-fore, check rapid descent of the platen and also assist in returning it to its said vertical position.

The platens are maintained in spaced relationship and the molten metal may be confined in the casting chamber formed therebet-ween by gauges of any suitable construction. In the embodiment illustrated the gauges comprise longitudinally extending

bars

39 and 40, see Fig. 8, and a transversely extending bar 41 which are placed on the bottom platen over the matrix (not shown). The bottom platen adjacent one side edge is provided with a longitudinally extending groove in which a bar 42 is placed. A plurality of

links

43 and 44 are pivotally connected in parallelogrammatic relation. said links being placed on the bottom platen between the

bars

40 and 42. By tightening the thumb nuts 45 the

links

43 and 44 may be held in the desired rigid relationship and, when the bar 40 is placed against the inner ends of the links 44. it will be exactly at a right angle to the bar 41. Stop members 46 are mounted on the other side of the bottom platen. A plurality of

links

47 and 48 are pivotally connected in parallelogrammatic. relationship and are placed on the platen between the stop members 46 and the gauge bar 39. When the thumb nuts 49 are tightened. the

links

47 and 48 may be held in the desired rigid relationship and, when the bar 39 is placed be flush with the top surface of the platen platen is pivoted to the rod 29 in when said members are turned properly. The purpose of this arrangement will presently appear.

The gauge bars shown in the drawings are type-high. The respective L-shapedlinks 28 are provided with adjusting screws 50, see Fig. 9, which are adapted to bear against the under side of the bottom platen. The screws 50 are adjusted in the links so that the tops of the gauge bars will be on a line with the axis of the rod 29. The top manner to bring 1ts up or surface also on a line with the axis 0 the rod. The top laten, therefore, may be swung over ontot e top of the gauge bars without shiftmg the gauge bars on the bottom platen. When castings less than type-high are to be made, thinner gauge bars, of course, are used and, in that'case,"the. screws 50 areadjusted to raise the bottom platen. The means for connecting the bottom platen to the rod 29 and its adjustment to accommodate gauge bars of various heights isfully described and claimed in theco-pending application of Milan H. Fisher Serial No. 597,386, filed October 27th, 1922.

The means for clamping the'outer ends of the two platens together includes a hook member 51 mounted on each side of the top platen which is operated'by a handle member 52, the hook member 51 being adapted to engage a reversible catch 53 mounted on the side of the bottom platen. The clamping means mentioned is described and claimed in my co-pending application Serial No. 676,561 filed November 23, 1923.

When the top platen is swung over onto the bottom platen and clamped thereto. the two platens may be moved into the casting position shown in Fig. 2 by permitting the rod 29 and its rollers 30 to descend'in the vertically extending guideways formed in the channel members 22. I preferably provide means to pre'vent the platens from moving into the casting position too rapidly and also to aid the operator in moving them from their casting position to their cooperative. horizontal position. In the embodi-- ment herein shown, arms 54 are fixed at one end on the rock shaft 32, the arms 54 in conjunction with the respective arms 31 constituting a pair of bell-cranks. The free ends of. U-shaped stra members 55, see Fig. 5, are pivoted to t e free ends of the respective arms 54, a stop member 56. ex-

tending through each of the members 55. medial portions of Urshaped' strap the sides blocks 58.

members 57 rest on top of" there ective members 56. The arms of the mem are 57 extend downwardl against the sides-of the medial portions 0 the respective members 55 and against the sides of the transverse t1e-rod-21, being connected, res actively, to

ompression- I of blocks 58. springs 59 are coiled about the res ective co-operating

members

55 and 57, bem terposed between the members 56 an the With this arrangement, when the two platens are moved from their co-operative horizontal position into their casting position, the springs 59 are compressed and rapid descent of the two platens is effectively checked. The springs also aid materially in moving the two platens from the casting position int-o theirco-operative horizontal position.

x The means for locking the bottom platen in its horizontal position preferably includes stop members 60. see Fig. 6, operating in suitable registering slots provided in the respective channel members 22 and plates 24, said stop members, respectively, being mounted on springarms 61 fixed at their lower ends to the outer sides of the respective channel members. the-stop members are inclined or beveled at 60" and the spring arms 61 are so formed that the stop members 60 are normally positioned directly in the path of the respective rollers 30. Vhen the platens are being moved from their casting position to their co-operative horizontal position, the rollers 30 readily move by the respective stop mem here 60 and the spring arms 61 instantly act to force the stop members inwardly under the respective rollers, thus locking the rod 29 against downward movement in the guideways and consequently locking the bottom platen in its horizontal position. The stop The under sides of members may be readily withdrawn from:

the paths of the respective rollers 30 by pulling outwardly on the upper ends of the spring arms 61.

A burner 62 is positioned under the metal pct 33. A burner 63 is preferably attached to the-back side of the bottom platen 27. Since the burner 63 swings with said platen, it is provided with a flexible tube 63 for supplying fuel thereto.

When itis desired to make a casting, the platens are moved into the positions shown in Fig. 1.- The metal in the pot 33 is heated by the burner 62 and, since the platen 36 rests on top of the metal pot, it is also heated while the metal is being heated. The matrix is placed on the platen 27 and the gauge bars properly arranged thereover. If

desired. the bottom platen 27 may be preover onto the platen 27 and clamped thereto.

The spring arms 61 are pulled out to with- Wardly on the rail 66 by a-handle 77, the

' draw the stop members 60 from underneath upper end of which is secured to the rear the respective rollers 30 and the hingedly end .of the member 68 and the lower end connected ends of the two platens descend, of which is secured to a plate 78 attached to the platens swinging into the vertical or the member 68, the plate 78'serving to precasting position. As shown in Fig. 8, the vent the hand of the operator from coming platens are provided with a plurality of into contact with the saw. The driving longitudinally and transversely extending means for the saw preferably includes a ribs to stiffen them and prevent them from shaft 79, see Figspl and 2, journaled in warping. By. reference to Fig. 7, it will be suitable bearings provided on the frame of observed that the free ends of the arms 31 the machine and carrying a beveled gear 80. bear against the under side of the back of The lower end of the shaft 81 is journaled the bottom platen and the under side of one in a head 82 which is rockable on the shaft of the transverse ribs. The arms 31 are 79, said shaft 81 having a beveled gear 83 notched at 64 for the reception of pins 65 in mesh'with the gear 80. The upper end of fixed in the platen, whereby the upper ends the shaft 81 extends into the lower end of of the two platens may be swung away from a tubular shaft 84, the upper end of the or toward the metal pot to bring the casting latter being journaled in a head 85 formed chamber directly under the mouth of the integrally with the hub member 70, the shaft metal pot when tilted. The molten metal, 84 being provided with a gear 86 in mesh therefore, may flow directly from the metal with the gear 7 5. The

shafts

81 and 84 have pot into the casting chamber. After the a splined connection, one having a longitucasting has been made, the platens are swung dinally extending slot while the other has a from the vertical or casting position back rib or a pin ada ted to fit into the slot. to their co-operative horizontal position.

A rail 66, see Figs. 12 and 13, is fastened In the construction shown in Figs. 14 and to one side of the platen 27 by bolts 67. The 15, the beating brush 94 is mounted on the frame of the saw includes a member 68 lower end of a rod 95 reciprocably mounted which is slidably mounted on the rail 66 in a casing 96. The upper end of the rod by a plurality of L-shaped retaining mem- 95 extends into a casing 97 which is made bers 69. The member 68 carries a hub memin the form of a handle.

The saw a gear 101 in mesh with a pinion 102 mount frame may be moved backwardly and fored on the armature shaft of a motor 103,

. ing the beating brush.

-A cam member 104 is fixed to one side of the gear 101 and bears against a rollerv 105 mounted on the side of the rod 95. The motor drives the gear 101 so that it rotates in the direction indicated by the arrow, Fig. 15. When the part 104 of the cam passes from underneath the roller 105, the rod 95 descends and the bristles of the brush 94 impart a quick blow to the flong placed on top of the ty e. The jointed arms 91and 92 permit the heating brush to be moved to any desired position over. the flong. The arrangement is such that the lower ends of the bristles of the beating brush, when the brush descends, do not quite touch the bottoms of the various recesses in the type; conseuently, the bristles of the brush while effectively beating the flong into the type, do not break or weaken the flon in doing so. In the construction shown in Fig. 16, the 'cam member 104 is connected directly on the end of a shaft 106, the latter being connected to a flexible shaft 107 which is attached to any suitable power means,'for example, the motor 90. With this arrangement one motor may be made to serve as a power means for driving the saw and also for driv I In the construction shown in Fig. 1 7, the beating brush is operated by pneumatic means. The brush is mounted on the lower end of a stem carried by a piston 108 which operates in a cylinder 109. Air under pressure is admitted to the cylinder through a pipe 110 and an opening 111 in the cylinder wall. The piston 108 is provided with an external circumferential groove 112 and a 'sageway 113, radial vertical passageway 113. radial passageways 114 lead from the groove 112to the passageway 113. The piston is provided with an annular shoulder 115 and the cylinder is provided with a similar shoulder 116. A compression spring 117 is coiled about the piston 108, being interposed between the

shoulders

115 and 116. The cylinder walls are provided with outlet openings 118. The spring 117 normally maintains the piston 108 in its uppermost osition. When air is admitted to the cylin er through the opening 111, it passes into the groove 112, through the radial passageways 114, and the vertical passageway 1 13 and a pressure 18 built-up on top of the piston which forces the piston downwardly into itsjdotted line position, thus causing the brushto descend and beat the flong into the? p 'I When the piston is in its' dotted.,line. o'sition, the air escapes from the cylinder 't rough the passageways 114, groove 112, and the outl' upon, the spring 1 ,eturns the piston to It will be obvious from the foregoing description that a -machine embodying the principles of my invention may be used for type in between, thereby drying t A plurality of penings 118, wheresecond, for baking or drying the flongs, inv

which case the burner 63 may be utilized to heat the bottom platen and the to platen may be heated by the burner under t e metal pot, the two heated latens being then clamped together with t e wet flong on the I e flong from both sides simultaneously; third, for making castings from the matrices; andfourth, for sawing the castings after the have been made. The construction is suc thatthe saw ma readily be removed from the rail 66 whi e matrices or castings are being made, and the beating brush may be swung to one side out of the way when cast- 1ngs are being made or sawed. When the matrices are to be made or a casting is to be sawed, the bottom platen serves as a convenient work table upon which to perform the work while the top platen may be used as an extension of the table u on which the gauge bars, etc. may bev place By adjusting the feet 25 relative to the frame the table may be positioned at the height most conven- 1ent, to the operator. The platens, when in the position shown in Fig. 1, may be used as a convenient work table for many purposes. Furthermore, the constructionv of the machine is such that it may be sold as a casting machine without the saw and beatin brush arrangements, thus lessening the initial investment of the purchaser. The

purchaser may subsequently add either the sawor beating brush arrangements, or both,

whenever .desired.
