G. L.. CURLE WASTE METAL GATCHER FOR TYPE CASTING MACHINES Filed May 12, 1941 2 Sheets-Sheet 2 d( um@ Patented Jan. 13, 1942 WASTE METAL CATCHER FOR TYPE CASTING MACHINES- l2 Ciaims.

My present invention relates to improvements in Waste metal catchers for use in connection with type casting machines. While this invention is intended for general use, it is especially Well adapted for use in connection with Waste metal spouting systems of the type disclosed and broadly claimed in my two United States Letters Patents No. 1,875,565 issued September 6, 1932, and No. 2,186,801 issued January 9, 1940.

The object of these' spouting systems is to receive and 'collect waste metal cut from type slugs or bars by the back knife, waste metal spill from the mold wheel, shavings removed from type slugs bythe knife wiper and waste metal and dust from a type slug sawing attachment, provided the type casting machine is equipped with the same.

These catchers are provided and arranged to receive Waste metal discharged from spouting systems at the terminals thereof and to receive rejected type slugs thrown by .hand by the operator of the machine.

More specifically stated, this invention is in the nature of an improvement or a refinement on the waste metal catchers shown in the above identified patents wherein the waste metal catchers are removably moimted on under-slung brackets detachably secured to the machines. These brackets are objectionable for the reason that they materially interfere with the care of the machine and the floor thereunder, as Well as certain adjustments of the machine that have to be made from time to time, and said brackets often have to be removed from the machine in order to make the required adjustments.

One of the objects of this invention is to removably suspend the receptacle of the waste metal catcherfrom an overhead support or cover, whereby when said receptacle is removed therefrom, the space below said support or cover is unobstructed.

Another object -of this invention is to provide means whereby the receptacle of a Waste metal catcher will freely slide from an overhead support or cover when removing said receptacle therefrom to empty the load of waste metal therein.

kA further object of the invention is to provide an overhead support or cover for the receptacle of a waste met-al catcher that will directJ` Waste metal from a spouting system or thrown by hand without 'spill or over-shot.

Still another'object of this invention is to provide an overhead support or cover for the receptacle of a waste metal catcher having a novel apron for directing Waste metal from a slug sawing attachment into the receptacle.

These and other objects of the invention will be apparent from the following description and accompanying drawings.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illus; trate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 9 is a fragmentary detail View partly in plan and partly in horizontal section taken on the line -Sl Yof Fig. 3.

Oi" the parts of the type casting machinefragmentarily illustrated for the purpose of showing the invention in working position, it is important to .note the central supporting pedestal l0, the

.horizontal left-.hand member or angle bar H of the main frame having on its front end a bearing t2, the upright standard I3 on the member I l that forms a part of the main frame, the transverse shaft lll journaled at one end in the bearing l2, the left-hand leg l5 -of the melting pot, not shown, pivoted on the shaft I4, the left-hand leg l of the vise frame, not shown, pivoted on the shaft ifi, the lefthand justification lever I'I and its rod. i8 and operatingv spring lil and certain ,parts of the quading and centering mechanism indicated as an entirety by the numeral 2D.

Mounted on the type casting machine and fraginentarily illustrated is a spouting system, and of the parts thereof shown it is important to note the discharge end portion of a spout 2l that collects andccnveys waste metal taken from slugs by the back knife, and the delivery end portion of a spout 22 that collects and conveys waste metal spill from the mold wheel and shavings removed by the knife wiper. rI'he spout 2l is provided with an auxiliary extension 23 having a depending lip 24. The numeral 25 indicates the discharge spout, fragmentarily illustrated, of a slug. sawing attachment, not shown. The discharge spout 25 extends transversely in front of the leg l and is secured thereto.

Referring now in detail to the improved metal catcher, the numeral 26 indicates a scoop-like receptacle having an open top. In the front member of the receptacle 2G is a hand hole 21 and an intermediate transverse handle 23 is secured at its ends to the sides of said receptacle at the top thereof. The upper edge portions of the side members of the receptacle 26 are turned outwardly into horizontal positions to aord at each side of the receptacle 26 a longitudinal flange or rail 29.

The receptacle 23 is removably suspended from the type casting machine by means of an overhead support or cover 30. This cover 39 is located on the left-hand side of the type casting machine and extends from the front toward the rear thereof. The major portion of the cover 3B is outwardly of and below the frame member l l. The left-hand side member of the cover 30, at its rear end portion and top thereof, is inset at 3E to receive the front end portion of the frame l l and its bearing I2, see Fig. 6. The cover 30 is detachably secured to the frame member ll by bolts 32, and its top member is downwardly and outwardly inclined from the upper face of said member and ailords clearance for the left-hand justication lever l1 which works thereabove.

The receptacle 26 is removably supported from the cover 30 by means of rollers 33 on which the tracks 29 rest. These rollers 33 are journaled on the side members of the cover 30 at the inner faces thereof in longitudinally spaced arrangement. The rollers 33' are located at the lower edge portions of the side members of the cover 30 and the front member of said cover, at its lower edge portion, is cut away at 34 to permit the receptacle to enter the cover 30 by sliding its rails 29 on the rollers 33, see Fig. 6.

On the front member of the cover 3i] are outwardly extended iianges 35 arranged to engage the front ends of the side members of the cover 3) as stops to limit the movement of the receptacle 26 under said cover and position its front member in the plane of the front member of the cover 30.

On the right-hand side of the cover 30 at the front thereof is a hopper 36. The auxiliary spout 23 and its lip 24 are arranged to discharge waste metal received from the spout 2| into the hopper 36 `at the rear end thereof and the spout 22 is also arranged to discharge waste metal into the hopper 36 at the rear end thereof.

It is well known that the legs o the vise frame, which are pivoted on the shaft I4, swing forwardly when said frame is opened and hence the discharge spout 25 of the slug-sawing attachment which is secured to the vise frame leg IB moves therewith. In View of this movement of the spout 25 relative to the hopper 35, said spout cannot be arranged to extend over said hopper and discharge waste metal directly there- To carry waste metal from the spout 25 and discharge the same into the hopper 35, I provide a novel apron 31. This apron 31 is connected at its lower end by a hinge 38 to the upper edge of the right-hand side of the hopper 35. Said apron 31 is upwardly and outwardly inclined away from the waste metal catcher and bears its upper end against the leg l5 and holds said apron under the spout 25. In the upper end portion of the apron 31 is an intermediate cam surface 39 that normally extends in front of the legs I6. Vvhen the vise frame is opened, its leg I6 engages the cam surface 39 and moves the apron out of the path of movement of said leg. Gravity holds the apron 31 against the leg I6 and returns said apron to operative position when the vise frame is closed. On the front edge of the apron 31 is a perpendicular flange 40 that extends into the hopper 35 and overlaps the front, member thereof.

Waste metal discharged into the hopper 36 from the spouts 2| and 23, 22 and 25 is precipitated through said hopper and the cover 30 and into the receptacle 26.

The left-side member of the hopper 36 is extended above the front member of said hopper to aiToi'd a deilecting ilange 4I for intercepting discarded slugs thrown by the operator over the hopper and directing the same therein.

By reference to Fig. 1 it will be noted that the quading and centering mechanism 20 is substantially entirely rearwardly of the receptacle 26 and the cover 30 and the major portion thereof is below said cover.

When the receptacle 23 is removed from the cover 30, free access may be had to the quading and centering mechanism 2U and other parts of the machine normally covered 01 obstructed by said receptacle. The entire space between the cover 30 and the iloor at, when the receptacle 25 is removed, is unobstructed.

As the improved waste metal catcher is substantially entirely to the left of the type casting machine, it is not in the way of the operator of the machine or does not interfere with access to the machine from the front thereof.

From what has been said, it will be understood that the waste metal catcher described is capable of modifications as to details of construction and arrangement within the scope of the invention herein disclosed and claimed.
