ing is a speci '10 :To all witom it mag concern:

Be it known that I, ABRAHAM HOYT LEVY, a citizen of the United States, of America; residing at the borough of Bronx, in the 1 cityof New York, county-of Bronx, and:

' State of New York, have invented certain paratus using a flux, although not. restricted tion, comparatively cheap in manufacture,

the melting pot, and shows the/cleaning apparatus fastened in operative posltion; Flg.

to such apparatus; and an object of this invention isto provide a metal-cleaning apparatus which will be simple in construcand efficient and, labor-saving in operation and use. l I

In the drawings illustrating the principle of this invention andtthe best mode now .known to me of applying that principle,

Figure 1 is a front elevation of the furnace with the metal-cleaning apparatus in'place; Fig. 2 is a fragmentary central vertical sectionon the line 22-of Fig. 1 and through 3 is a plan of the cleaning apparatus ole-- tached from the. furnace Fig. 4 is a. detail showing the shell in vertical central section;

paratus sho .modified form of cleaning apparatus in place Fig. 5 is a perspective view illustrating a in the melting pot of' a furnace, parts being broken away to permit of clearness of illus trationgFig. 6 is a plan of thecleaningl ap- Wn in Fig. 5; and Fig. is" an elevation of asecond modified form of 'the cleaning apparatus. The furnace a is provided-with" afire pot door 6 and'with a pair of doors 0 which 'close the opening d to the 'melting-pot e. In the latter, the metal 1 (such as type metal) to be cleanedis sub ected .to. heat,

until the metal is ina molten condition.

1 The cleaning apparatus consists of a hanc'rosspiece hfthat serves as die-bar 9 formed, at its outer end, with a a handhold and,

Serial 1%. 201,222. g r

at its inner end, with a tubular guide-mem- Mber z, in which there is slidably fitted avertically-disposed rod 7' the lower end of which is fastened to the hinged cover k of a shell'm formed with perforations o. The cover is is hinged at p to the shellm,. which is formed with an ear 9, with which is engaged the ha'sp' 1!, whereby the cover-k is held locked down in place on the shell m. A gas-liberating flux '8 is held in a container 1t made of perishable material (such as pasteboard orthe like) and shaped like, acartridge and having its lower end t pointed (or conical) in shape and its top t" formed with an annular flange t". The conical end t of the container t fits snugly into thejconical lower ,end m of the shell m,"

f and the flange t" of the container 15 serves to hold the cylindrical wall t* spaced from the cylindrical wall m of the shell m.

. Bymeans of a set screw it, the. rod 9' is held in its adjusted position. Upon the bottom edged of the opening d, there is mounted a'clamp 1:, the outer end of the body 0 of which is formed-with an ear '0", through a threaded opening in which there is passed. a clamp-sorew 'w having at its outer end. a handwheel 'wf. The inner end of the body '0 of the clamp '21. is bifurcated and each branch or fork 'v" is formed with a lip 12*, between which and theinner end of the clamp-screw w, there passes the bottom edge portion (1" of the opening (1. By means ofa set screw w, thehandle-bar g is held in its adjusted position in the clamp 21. v

The operation ofthe cleaning apparatus 'hereinbefore described is as followsz A gas- -liberatingllux is-placed in the pasteboard,

cartridge-shapedsbpx t, which ls'then' inserted in the'shell m, whereupon the coverla 0f the latter is closed and, by means of the 1 atented'M94225", 1919} I hasp 1", is locked down upon the shell m.

The position of this shell m may be adjusted vertically by loosening the set screw u and slipping the rod j up or down in the guide 71, as may be deslred; and, after the vertical adjustment has been made, the set screw to is tightened. The clamp 'v is fastened to the edge portion d ofthe wall of the melting-pot e by tightening the -screw' w; and the handle-bang is inserted in the clamp 41 and, after having been adjusted horizontally to its properv position, the set screw as is tightened. lfhe molten typemet'al enters the foraminatedv shell 'm through the perforationsfo .formed therein and the pasteboard box tis thus destroyed,

A ma be used depending on the nature of the whereupon the flux s flows out through the I holes and mixes withthe molten typemo ten metal and the size of the melting used, pots for 'linotype metal being small and those for stereotype metal being larger.

' and requiring two or more weights 2 to be metal f. The mixing of the gas-liberating flux o with the latter causes an agitation of the molten metal by the liberation of gases,

' as .well as. serves to clean the same. .This

agitation serves to obviate the necessity of stirring the-metal 1, while it is being melted.

.Moreover, this cleaning apparatus ,does

away, with the necessity of .a workmans holding down the shell m; and, since the apparatus may be adjusted both horizontally and vertically, the shell mmay be quickly put in the melting-pot ein any position desired withouthaving to exercise great care with regard thereto; and the apparatus may be readily fitted to melting pots of different used.

Another means of. overcoming the buoyant elfort'ofthe molten metal mechanically consists in utilizing for this purpose thejweight of a standard-similar to that used by the I sizes and capacities. 'The buoyant effort of the molten metal f is considerable and taxed greatly the strength of the workman who was, in the methods heretofore employed,

. the

charged with the duty of holding the fiuxcontainer in the liquid metal- By-means of the structure hereinbefore described; the

buo ant effort is resisted mechanically.

ases arise in which the bottom edge portion of the opening it is not well adapted for use with the clamp c; and, for such cases, I have. 'rovided the form of apparatus illuspolice of large cities for the purpose-of regulatin street trafiic. This device is illustrate in Fig. 7, wherein the outer end of the horizontally-disposed, shell-supporting bar gf is bent vertlcally downward to form a leg 9* which enters slidingly the socket in the standard orpost 6 that rises, pedestallike, fromthe base 7. By means of a setscrew 8, the leg g is secured in adjusted position'; and the'buoyant effort of the molten metalis effectually resisted 0st 6 and its base 7. I T is application is filed as a continuation of my 89742, filed April 8, 1916. i

I claim:

1. Ametal-cl'eaning ap-paratusincluding a receptacle; 2. rod to WlllCh said receptacleis attached; a handle-bar in which said rod is thereto; and means for maintaining said by the weight or handle-bar against the thrust due to the trate in Figs. 5 and 6. .In this form, the a clamp eis' entirely omitted and the handle g is simply laid upon the bottomedge cl" of the opening 01. To the inner end of the handle there is fastened anj L-shaped bracket 3 the vertical art 3 of which suprts the outer ends 0 a pair of bars a, the;

inner ends of which are formed with guides 2', through which are slipped the rods j that carry, at their lower ends, the shells m and that are fastened in-itheir adjusted position by means of the set screws u. On each .of

the bars 2, between the vertica l part 3 of guide 2', there is -slidthe bracket-y and the ably-mounted a block of metal 2 the weight of which resists the upward thrust due to the buoyant effort of the moltenmetal 7. By shifting the sition of the metal blocks 2, thls buoyant e ort may be. nicely balanced.

.By turning the vertical party of the bracket .31 upward, the weights 2 are held abovethe level of the metal f, in case the melting-pote becomes. well-filled. The cleaning appa ratus maybe compactly arranged for storage, when not in use, as is illustrated inFig. 6 in dotted lines. The set screws u] are loosened, the rods 7' are withdrawn from the mounted buoyant eflort of the molten metal in which said receptacle is held.

2. A metal-cleaning apparatus including a receptacle; 9. rod to which said receptacle is attached; a handle-bar in which said rod is mounted and which is angularly disposed thereto; and a weight for counter-balancing the thrust due to the-buoyant efl'ort of the molten metal in which said receptacle. is

its counterbalancing e ect.

receptacle; a rod to which said receptacle is attached a handle-bar in which said rod is thereto; and a weight for counter-balancing the thrust due to .the bou ant effort of the molten metal in which sai receptacle is held; said handle-bar being formed with a raised portion by means of which the",v

and. which is angularly disposed.

weight is kept at all. times-above the level of the molten metal.

4. A metal-cleaning apparatus including a receptacle; a-rod to which-said receptacle is mounted and" which is angularly disposed thereto; and a weight for counterbalancing attached; ahandle-bar in which said rod'is 1'10 held, said weight bein adjustable to vary 1,298,229 a a a the thrust due to the buoyant effort of the New York, this IllIlth day of November, molten metal in which said receptacle is I 1917, in the presence of the two undersigned held, said weight being formed with an witnesses.
