BALBBITTING APPARATUS.

Patented Feb. 24, 1920.

Application filed July. 11, 1919. Serial No. 310,110.

will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanyand to numerals of'reference ing drawings 7 forming a part of this marked thereon, specification.

My invention relates to machines for east ing small articles of various kinds and classes of metal, as for instance, for applying Babbitt metal'to engine connecting rods; and the object thereof is to provide an improved machine of this class which is simple in construction and eflicient in operation,

and which may be conveniently manipu- 'lated.

The primary objectof my invention is to taketlie usual connecting rod having a wrist pin bearing at one end thereof and a crank pin bearing box at the other end, said crank pin bearing box usually comprising two halves the former of which is integral with the rod, and the latter of which is separate and may be attached to the former by bolts extending through both and retained in place by nuts, and to cast a Babbitt bearing in the crank pin bearing box which will not be spongy or porous, but possessed of the requisite density.

WVitli these and other objects inview the invention consists in novel details of construction and combination of parts more any hereinafter disclosed and particularly pointed, out in the claims,it being underthe precise embodiment of the invention herein disclosed can without departing from the spirit of invention.

The invention has'been illustrated in its preferred embodiment in the accompanying drawings; wherein: p V 1 Figure 1 represents, a longitudinal section of the upperand lower divided dies with the core in position and showing in dotted lines a connecting rod clamped in operatlve position between the said upperand lower divided'di'es.

arranged passages die 2 and from Fig. 2 represents, a view'of the upper die looking at it in the direction indicated by the arrow shown at the left in Fig. 1

Fig. 3 represents, a view of the lower die looking at it in the direction indicated by'the arrow shown at the right in Fig. 1

Fig. 4 represents, a transverse section taken on linens-4v in Fig. 2.

, Fig. .5 represents, a' transverse section taken on line 00-02 of Fig. 3.

Figs. 6 and 7 represent, respectively, end and side elevations ,of the completedbabbitte'd bearing removed -.-r1-0m the connecting rod.

Fig. 8 represents, a side elevation of the .babbittedbearin'g as it leaves the divided dies, and shown removed from the connect- 7 ing rod. V

1g. 9 represents, an end view of said bearing looking in the direction indicated by the arrow in Fig 8. p Fig. 10 represents, a transverse section taken on line mm of Fig. 8, and looking in the dlrection of the arrow; and

Figs. llqand 12 represent, respectively,

side elevation and an end view ofthe core used in connection with the divided dies.

Similar characters of reference are shown in all of the above described views, to indicate corresponding parts. i r

In the drawings 1' represents the upper divided die;.2 represents the lower divided die and 3 represents the core which is movablysecured to the platen 4 to which thegupper die 1 is secured, and which engageswith both the upper and lower dies as. clearly illustrated in- Figpl of the drawings.

The dies 1 and 2 are connected in the usual 'manneras is common in die pasting machines so that the two dies and'core can be brought to ether in the positionillustrated 1 he drawings with the recessed portion 6, in the undersideof the platen 5,

fitting over the outlet of the cylinder containing the molten metal, not shown.

The molten metal, as is-comnion, passes "from the outletof the cylinder containing the same into the diametrically, oppositely 7 and 8 whieh are, arranged one in each section 18of the divided there is forced upward througlrsaid die around the core 3 into the crank pin bearing box of the connecting rod 9 illustrated indotted lines in Fig. l of the drawings, and'tlience upwardly into the die produced possessing the highest degree of density and one that will not be spongy or porous. V

The upper divided die 1 consists of the two sections l0 fitted into suitable gibs 11-11 secured to the under side of the platen 4, and is provided with the cylindrical aperture 12 and a series of stepped portions 13l313 designed to receive the .cylindrical portion 14 and the stepped portions 1515l5 of the core 3.

The apertured portion 12 of the die 1 is further provided with preferably four pads 16 which'contact with the part 14 of the core 3 and which form the vents 17 of'the babbitted bearing illustrated in Fig. 8 -of the drawings.

. The lower divided die 2 consists of two sections18-18 fitted into'suitable gibs 20 secured to the upper side of the platen '5,

the central portions of the sections 1818 are recessed to receive the core 19, which is secured to the platen 5 in any desired or convenient manner. 7

In each section 18 of the lower die 2 passage ways 7 and 8 are formed to permit the molten metal to be forced, from the cylinder containing the same, into the said passage ways and up around the cylindrical portion 21'0f the core 3. V

The end of the core 3' adjacent to the cylindrical portion 21 is provided with a projection 22 designed to be received into the aperture 23 of'the core 19, in order to properly position the core 3 with relation to the dies 1 and 2.

It will thus be seen that if the compression lever of the machine (which is not here shown) is given the usual quick hard pull the molten metal from the cylinder containing the metal will be forced into the lower die through the passages 7 and8, then into the crank pin bearing of the connecting rod 9 around the portion 21 of the core 3 and up into the upper'die around the cylindrical portion 14 of the core 3 where the metal is restricted and deflected in its path by coming into contact with the stepped portions 1501 the core and'the stepped portions 13 of the die 1.

Before] the metal reaches the largest stepped portion of the core and die it usually becomes chilled and forms a seal.

The section 10-10 adjacent the upperis always found in the cylindrical wall 26 Figs. 6 and 7 of'the drawings.

most stepped portion 13 are cutaway as illustrated at 24 to provide a passage way for the escape of the air which is in the space surrounding the core 3. y

From an inspection of F igs.16 and 7 of the drawings, which shows the completed babbitted bearing removed from the connecting. rod bearing, and an inspection of Fi 8 of the drawings which illustrates the babbitted hearing as it leaves the upper and lower dies, the same is shown provided in Fig. 8 at one end with runners 25, and at its upper end with the cylindricalwall'26,

' cylindrical stepped for the molten metal. I V V The porous or spongy part of the metal and the stepped portions 27 which, of course, is to be understood are to beremoved as well as the runners 25, in order to form the completed bearing as illustrated in i It will thus be seen that bythe employment of the two dies and the core,"the upper die being provided with a plurality of stepped portions corresponding with a similar pluralityof stepped portions formed on the core, I am enabled to provide a stepped passage way for the metalwhich as it enters the passage ways in the lower die is forced around the core,therebyexpelling the air from around the core and filling up the air stepped portion onto the other, until it 110.

reaches the uppermost stepped portion where it is chilled and forms a tight seal.

7 Experience has demonstrated that the organization abovegdescribed is a highly efficient one, and while I have shown the preferred embodiment of my present invention,

I do not wish to be limited to the exact details of construction shown and described,

as obvious modifications thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such departures from what is herein set forth, I consider within the scope and terms of my claims.
