10 Claims.

My present invention relates totype casting machines, and more particularly to the embodiment of a spouting system therein for collecting and conveying to a receptacle waste metal such as molten metal, that escapes during casting operations or that is spilled from the melting pot, shavings cut from type bars by trimming knives. dust and waste material cut from type bars by a sawing device on the machine, discarded type bars` and the like. v

This invention is in the nature of a modification or renement of the spouting system for type casting machines disclosed and broadly claimed in my United States Letters Patent No. 1,875,565, issued September 6, 1932.

An object of this invention is to increase the efficiency of the spouting system by a novel arrangement of the several ccf-operating parts thereof.

A further object of the invention is to mount the several parts thereof in convenient and accessible places relativeto the machine, whereby they may be quickly and easily installed as at- I tachments.

Another object of the invention is to provide a spouting system that can be manufactured at bodied therein, some parts being` removed and otherv parts being sectioned; Fig.- 2 is a fragmentary view'in left-hand elevation;

Fig. 3 is a fragmentary view partly in elevation and partly in 'section taken substantially on the line 3-3 of Fig. l;

Fig. 4 is a fragmentary view partly in plan and partly in section, taken substantially on the line 4-4 of Fig. l, with some parts removed and other parts shown by means of broken lines;

Fig. 5 is a fragmentary View partly in elevation and partly in section taken substantially 'on the lyineS--S of Fig. 1;

a front handle 2l and a transverse handle28 lFig. 2. This hanger 29 further includes a pair the bracket and v cipally in section taken on the line H--H of V Fig. 10.

Oi the parts of the type casting machine illustrated for the purpose of showing the `invention applied thereto in working position, it is important to note the main frame l2, ring gearequipped mold disc i3 journaled to the slide Ill on said main frame, driven pinion l5 meshing with said ringgear, mold pockets i6 in the mold disc I3, molds Il in certainl of said pockets, rear trimming knives i8 mounted on the slide I4 for trimming the bottoms of type bars, not shown, in the molds Il under rotation of the mold disc I3, justification levers IS'on the main frame l2, whichv extend transversely of the mold disc I3 and are spaced therebelow, melting pot having a pair of depending legs 2l pivoted on a horizontal shaft 22 journaled on the main frame i2 below the mold disc I3 and extending parallel to the plane thereof, vise'frarne 23 pivoted on the shaft 22 between the legs 2l for outward swinging movement, front trimmingknives 24 mounted on said vise frame, and wiper blade 25 for the front trimming knives 2li. It will be noted by reference to Fig. 3, thaty the mold disc I3 has on its perimeter a rearwardly projecting annular ange. Y

Referring now in detail to the invention, to wit: the spouting system, the numeral 26 indicates a scoop-like receptacle having an open top,

secured to and between the sides of said receptacle. The receptacle 26 is held suspended abo-ve the floor line :l: by a hanger 2S which extends transversely under a 10W member l2', forming a part of the left hand side of the frame l2. Forming a part of the hanger 29 is an upstanding transverse ange 36 which extends parallel tothe outer face of the frame member l2' and is detachably secured thereto by a screw 3l, see

of wide side members 32, the lower edges of which are turned horizontally inward to afford a pair of guide rails 33 on which the receptacle 26 is slidably mounted and has a working t between said side members.

It will be noted that the receptacle 26 extends transversely of the machine so that the same may be removed from the hanger 29 at the lefthand side of the machine and emptied to remove waste metal therein, without disturbing an operatorof the machine sitting in front thereof. It will also be noted that the receptacle 25 extends longitudinally under the mold disc I3 and its driving pinion I5, with its longitudinal center substantially directly under the frame member I2'. Ihe top of the hanger 29, outward of the frame member` I2', affords a cover for the underlying portion of the receptacle 26, leaving the rear portion of said receptacle open for the precipitation of waste metal therein.

A channel-like trough or chute 34 extends circumferentially under the mold disc I3 above the justification levers I9 and in the paths. of movement thereof. This chute 34, at its righthand end, is detachably secured to a bracket 35 by a separable hinge 36 comprising a horizontal transverse pin 31 on the chute 34 and a segmental socket 38 in the bracket 35. Said pin 31 is free for endwise removal from the socket 38 by an outward lateral movement of the chute 34. A stop lug 39 on the hinge pin 31 normally engages a shoulder 40 on the bracket 35 and holds the chute 34 in a forward and downward inclined position with its free end positioned over the receptacle 28. The outer side of the chute 34 extends above the under side of the mold disc I3, and the inner side thereof is upward and outward inclined and of such height as to freely pass under said mold disc during the removal of the chute 34 from the bracket 35. Said chute 34, at the free end portion of its bottom member, is bent abruptly downward to afford a lip 4I, which directs waste metal from the chute 34 downward into the receptacle 26 at substantially the center thereof.

The purpose of removably mounting the chute 34 is to permit the mold disc I3 to be moved forward by its slide I4 and out of mesh with the pinion I5, and expose the back of said disc or parts normally covered thereby.

Formed with the bracket 35 is an upward and rearward inclined apron 42 which forms a rear extension of the bottom member of the chute 34, and its outer end is substantially at the right-hand extremity of the mold disc I3.

Detachably secured to the vise frame 23, directly below the front trimming knives 24, is a defiector 43 having on its right edge a perpendicular flange 44. When the vise frame 23 is closed, the lower end of the deflector 43 overlies the adjacent portion of the chute 34 and its flange 44, which isI downwardly inclined to the left, and directs waste meta-1 onto the apron 42 and chute 34.

A wide apron 45 is detachably secured by screws to the legs 2l and is curved downward from the under side of the melting pot 26 to a. point in which it overlies the chute 34, at the back of the mold disc I3 and the rear end portion of the receptacle 26. Said apron 45, between the legs, is made transversely convex to draw waste metal precipitated thereon to a central point and discharge the same into the chute 34. This apron 45 also extends between the left-hand leg 2| and adjacent side of the frame I2 and overlies the receptacle 26.

The improved spouting system further includes an upright channel-shaped spout 45 arranged to discharge into the receptacle 26. This spout 46 is substantially transversely and centrally aligned relative to the plane of the mold disc I3, its sides are turned toward said disc and its back is substantially directly below the intermeshing teeth of the ring gear on the mold l0 disc I3 and the pinion I5. Said spout 46, at the lower end portion of its back, bears against the inner face of the frame member I2. To facilitate the mounting of the spout 46 on the machine, the same is made in two longitudinal 15 sections 41 and 48, the back members of which overlap. The spout section 41 is detachably secured at its upper end to the frame I2 by an angle bracket 49, one flange of which is permanently secured to said section and the other flange of which is detachably secured to the frame I2 by a screw 50 which extends through a notch in said section. To remove the spout section 41 from the frame I2, it is only necessary to loosen the screw 50 and move said sec- 25 tion downward to withdraw the bracket 49 therefrom. The lower end portion of the spout section 41 loosely extends between the bearing on the fra-me member I2 for the shaft 22 and an arm I9 on the left-hand justification lever I9, 3 and is thereby held against transverse pivotal movement on the screw 50.

The spout section 48 at its lower end, rests on the adjacent bearing for the shaft 22 and around which it is fitted. Said spout section35 48, at its upper end, is extended upward and outward to afford a deflecting flange 5I which underlies the pinion I5. The spout member 48 1s carried by a hopper 52 removably mounted on the hanger 29. Said hopper 52 has a vertical back member with which the side member of the spout section 48 has flat engagement and 1s rigidly secured thereto by rivets 53. The bottom of the hopper 52 is upward and outward,

inclined from the lower end of its back and the "15 sides of said hopper are parallel.

Formed in the top of the hanger 29, forward of the front end of the frame member I2', is an aperture into which the V-shaped lower end portion of the hopper 52 is sued. The upper end portion of the front hanger side members 32 is turned outward to afford a supporting flange 54 on which the hopper 52 rests and is detachably secured thereto by a thumb-nut-V equipped screw 55, which extends through aligned '55 By reference to Fig. 2, it will be noted 'that 65 the right-hand side member of the hopper 52 is extended below the bottom of said yhopper to afford a retaining member 58, for a purpose which will presently appear. member of the chute 34 is notched just above its lip 4I, see Fig. 1, and the overlying portion of said member is outwardly offset to receive the adjacent edge portion of the baffle 51 and thereby hold said chute 34 "against outward lat- "-75 The outer side '70 "lio vend to the sides of the spout iii?.l

vface of the gate 'fill is a ringer t5 that is overeral movement' that lwould tend to separate its metal out from type bars by a saw attachment applied to thetype casting machine. For the purposeI of this case, it is not thought necessary to illustrate a type bar sawing attachment, and hence only its discharge spout 59, into which dus't'and waste metal cut from type bars are precipitated, is shown. This spout 59 is narrow, deep and mounted on the vise frame 23 outward thereof, and is downward inclined toward the hopper 52. Said spouting is detachably secured at its upper end, by a screw E9, to the vise frame' 23, and at its secured lower end by a .hook and loop 6l, see Figs. 2 and 10.

The front end of the spout 59 is parallel to the adjacent sides of the hopper E and spaced therefrom to permit the required opening and closing movements of the vise frame 23 in which it swings on the shaft n Pivoted to the lowery end of the spout 59 is av short auxiliary spout 62 which extends into the hopper 52 through a notch (i3 in Ithel right-hand side member of said hopper.` During the initial opening movement of the vise frame 23, in which the samel swings downward, the auxiliary spout 62 enga-ges the lower edge of the notch t3 and further downward movement of the vise frame 23 will fold said auxiliary spout, as shown in Fig. ll, so that thesame will slide on the respective side member of the hopper 52 and its retaining member 58.

The lower end of the spout 59 is normally closed by a gravity-closed gate 64 hinged at its upper On the outer lapped by the auxiliary spout 52 when in an inoperative position, and holds the gate 64 closed during the opening and closing of the vise frame 23, so that in case there is any waste metal in the spout 59, it will be held there by the gate til until said vise frame is returned to its closed position,y and at which time the auxiliary spout 62 will drop by gravity into its operative position and release the gate 64. This locking of the gate E4, while the vise frame 23 is open, prevents waste metal in the spout 59 from being spilled on the iioor.

From the above description, it is evident that a squirt of molten metal back of the mold disc 34, during a casting operation, or a splash of molten metal from the melting pot 26, together with shavings cut from a type bar by the rear trimming knife it, will be precipitated onto the aprons ft2-i5 into the chute 34 and conveyed thereby into the receptacle 25, or precipitated directly into said receptacle. Any iiying pieces of metal, at the left-hand side of the mold disc I3, from the rear trimming knife i8 or other parts of the machine, will be intercepted by the trough it or the baille 5l and precipitated into the receptacle 25.

A squirt of molten metal, at the front of the mold disc i3, during a casting operation, or shavings cut from a type bar by the front trimming knives 24 which drop therefrom or that are removed therefrom by the knife wiper 25, will be directed by the deector lil and its flange M onto the apron i2 and into the chute 34 where the same is conveyed to the recep-tacle 25.

During the upward movements of the justification levers T9, the right-hand lever I9 engages the chute 34 first, and thereafter said chute is engaged by the left-.hand lever which carries the same out of the paths of movement of both of said levers. `The engagement of the chute 34 by the justication levers l shake said chute and thereby accelerate the ow of waste metal therefrom.

Dust and waste metal from the sawing attachment dropped into the spout 5t will be deliveredujo thereby over the auxiliary spout 82, into the .hopper 52 where the same willbe precipitated l disclosed andv claimed.
