MECHANICALLADLE-SKIMMER'AND HEAT-PROTECTOR.

To all whom it may concern:

Be it known that I, JosErH EDWARD FAZAKERLEY, a citizen of the United States, residing at 913 Tyler street, Pittsfield, Massachusetts, in the county of Berkshire, Massachusetts, have invented a new and useful Mechanical Ladle-Skimmer and Heat-Trotector, of which the following is a spec fication. j

This invention relates to molders pots or ladles and more particularly to improved skimming attachments therefor.

An object of the invention is toprovide an.

improved skimming device, applicable to-the usual molders ladle, whereby the molder may skim, hold back and prevent from flowing into the mold, all dross and flux.

, Another object is to provide a device of the class'described in Which the skimming blade is normally held away from the mouth 7 1 of the ladle but maybe conveniently depressed into skimming position by the molders" hand.

7 Another object is to provide in connection backin some manner to prevent its entrance into the mold. Commonly, an assistant takes a bar or other. implement and holds back the dross while the molder pours. While this methodis effective and satisfactory it requires additional labor. I seekto I provide an attachment to a molders ladle,

operated by the handof the molder. vAheat deflecting shield is mounted, adjacently to the skimming blade to protect the molders hands from the excessive heat of the moltenmetal. The skimming blade, isnormally held away from the mouth'of the ladle but can instantly be operated by the molder with one hand, when desired. When the blade is in depressed position it .lies insidethe ladle and closely adjacent the lip thereof, so that it holdsbaek the dross,'flux and cinder and prevents the entrance ofthesame into the;

mold. V j,

A preferred form of my invention is illustrated in. the accompanying drawings; in

which:

Figure 1 is a plan view of my plied to a moldersfhand-ladle; Fig.2 is an, I

elevational yi th and Fig 3 s ade; tail view of the skimming blade.

Referring to the drawings l represents I the usual molders ladle which'is provided] with the usual outlet lip-4. 2 is the usual;

ladle ring which receives and supports the conical pot 1, asclearly shown in Fig, 2. The ring 2is provided with a long handle] 3 which is formed integral therewith. 18, is

a semi-cylindrical member, 'hereinafter called the clamp member which is adapted 18 is, furthermore, 'provided with pairsof depending lugs 18 on each side thereof which extend below thehandle 3. Screws 19 i ..,9.5 .curely clampthe member 18 to the handle 3. L e

pass throughv each pair of lugs 18 and se The clamp 18 forms a' frame upon which all the parts of my device are mounted. i

Pivoted to the member 18 at 10 is a lever 6.; The portion of the lever 6, extending above the pivot 10, is adapted to receive the skimming blade and the heat deflector. The por:

pivot 10, is connected atll to a link 12. The latter is pivotally connected at'13to an upwardly extending member 15 which 'is tion of the lever 6, which extendsbelowfthex f V formed integral withaihandle 16. The ham 4 I dle 16 is. substantially semi-circular in cross section and is formedto fibth 1 1 ;.r v handle 16 together with the integral extension 15 is pivoted to the clamp member 18 at 14:- A coiled spring17, suitably mounted and interposed between the clamp member 18 and and handle 16, restrains the link and levers in the position shown in Fig. 1.

Secured to-the upper portion of the lever ed to lie within the pair of lugs 9, as clearly shown in Fig. 1. A thumb screw 7 passes through the lugs 9, lever 6 and the portion 5 and firmly holds these parts together. The screw 7 is adapted to rest in one of the recesses 21 and-by loosening the screw 7, the blade 5 may be moved relatively to the screw by'reason of the slot 20. Thus, the blade 5 may be secured in various positions of adjustment.

Fig. 2 shows the normal position of the parts of my device and it is to be noted that the skimming blade 5 is removed from the ladle 1.

In practice the ladle is carried by the molder with both hands. The upper portion of the handle is grasped by one hand and V the other hand lies on the handle 3 closely adjacent the handle 16. Consequently, when the molder desires to pour the contents of I the ladle 1 into a mold, he simply shifts his grip on the lower part of the handle 3 to cover the handle 16. When the latter is depressed the blade 5 is forced downwardly by the levers and link described, until it lies within the ladle 1 and beneath the surface of the molten metal therein. The blade 5 lies closely adjacent the lip 1 of the ladle as shown in Fig. 1. Consequently, when the molten metal is poured from the ladle the spoon shaped blade 5 withholds all flux,

dirt and dross from passing with the metal into the mold. As soon as the pouring operation is completed, and the molders hand is released from the handle 16, the blade is returned to the normal position shown in Fig. 2 by the spring 17. The portion of the blade 5 which lies in the molten metal becomes burned after extended use and the adjustable securing means shown in Fig. 3

7 permits the blade to be moved outwardly.

Thus, a fresh unburnt portion may be presented to check the flow of the dross. After the blade 5 has been completely used up, the screw 7 is loosened, the old blade extracted, a new blade inserted and the screw 7 is tightened. The operation of changing blades requires but a few minutes.

It is recognized that many changes may be made in the structure herein disclosed without departing from the scope of my invention which is defined in the appended claims.

What I claim is: r

1. The combination with a molders ladle and handle therefor, a member removably attached to said handle, a blade pivotally attached to said member and adapted normally to be held away from said ladle, means on said handle to move said blade to a position within said ladle and partially below the surface of themolten metal therein, whereby when the metal is poured from said ladle, all dirt and dress is held back and prevented from flowing into the mold.

2. The combination with a molders ladle and a handle therefor, of a frame removably attached to said handle, a lever pivoted to saidframe, a spoon shaped blade attached to said lever, said blade adapted normally to be held away from said ladle, and means to force said blade within said ladle adjacent the mouth thereof and partially below the surface of the molten metal therein, whereby when the metal is poured from said ladle, said blade skims and holds back the dross and prevents the same from flowing from the ladle with the metal.

3. The combination with a molders ladle and a handle therefor, said ladle being formed with a lip thereon, of a frame adapted to be clamped to said handle, a lever pivoted on said'frame, an operating handle pivoted on said frame, a link connecting said handle and said lever, a spoon shaped blade on said'lever, adapted, normally, to be held away from said ladle and adapted, when said handle is operated, to be lowered into said ladle to a position partly below the surface of the molten metal therein, and closely adjacent to the lip of said ladle, whereby said blade withholds the dross on the surface of the molten'metal from passing with the metal when the latter is poured from the ladle.

i. The combination with a molders ladle and a handle therefor, said ladle being formed with a lip thereon, of a frame adapted to be clamped to said handle, a lever pivoted thereon, an operating handle pivoted on said frame, a link connection between said lever and said operating handle, a skimming blade removably' attached to said lever, a spring interposed between said frame and said operating handle, said spring adapted to hold said blade normally away from said ladle, a deflector also attached to said lever and adapted to protect the molders hand from heat, when using said operating handle, said operating handle adapted, when depressed, to lower said blade within said ladle to a position partially beneath the upper level of the molten metal therein and closely adjacent the lip of said ladle, whereby said blade withholds all flux,

V dirt, and dross from leaving said ladle with the metal when the latter is poured into a mold. V

5. The combination with a molders ladle and handle therefor, a member removablyt attached to said handle, a blade 'pivotally attached to said member and adapted normallyto be held away from said ladle, means on said handle to move said blade to a-posi 7 tion within said ladle and partly below the surface of the molten metal therein, whereby when the metal is poured from said ladle, all

from flowing into the mold, and a heat'd'e-' flector located on said blade and adapted to 1.5

shield the vmolders hands from v the heat of: the metal within said ladle.
