MACHINE FOR REBAIBBITTING CONNECTING RODS.

Application filed April 24, 1924; Serial No. 708,784.

T 0 (ZZZ whom it may concern:

Be it known that I, CLIFFORD T'." SoNDLEY, a citizen of the United States, residing at Newberry, in the county of Newberry and State of South Carolina, have invented certain new and useful Improvements in Machines for Rebabbitting Connecting Rods, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to machines for casting, and particularly to mechanism for castinggBabbitt metal within the bearings of connecting rods.

One of the objects of the invention is to provide a machine of this character, which is very simple, which may be read.- ily operated, and which-is expeditious and effective inits work.

A further object is to provide a construc tion of this character wherein means are provided for clamping a connecting rod in place against movement, there being a core which fits within the eye of the conuecting rod, and providing a Babbitt metal pot normally containing melted Babbitt metal, the die, as it may be termed, with the connecting rod and the pot being relatively movable so as -to'bring'the parts toward each other and into proper engagement, means being provided then operating to force the Babbitt metal into the die and between the core and the wall of the connecting rod.

A. still further object is to provide a detailed construction whereby the die may be readily removed so that a new die may be put in place for casting the bearing of a larger or smaller connecting rod and whereby a proper adjustment may be secured between the die and the connecting rod and between the spout or nose of the Babbitt metal pot and the die.

Another object is to provide means for properly centering the connecting rod including pins adapted to pass through the bolthole openings for the bearing at this-- end of the connecting rod.

-Oth.er objects will appear of the following description. I

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional view through a mechanism constructed in accordance with my invention;

Figure 11 is aside elevation of the die plate core;

Referring to the drawings, the mechanism is'mounted within a frame consisting of the longitudinally extending members 10 and the transverse members 11. Th s frame may be mounted upon columns or otherwise supported at a convenient height above the floor. I and extending longitudinally thereof are four parallel rods 12 which pass through the end members 11 of the frame and are held in place by nuts 13. Also supported upon the frame at one endthereof by the transverse supports 14 is the melting pot, which is designated generally 15, and which is adapted to containBabbitt metal. The construction of this melting pot will be later stated.

Sliding upon the rods 12 is a supporting plate forming one part of a carriage, the plate being designated 16, and carrying the sleeves or collars17 which slidingly embrace the rods 12. Mounted upon this plate 16 by the bolts 18 is a yoke 19 which supports a transverse shaft 20 having a handle 21 at one end. Mounted upon the forward face of the yoke 19 is one section 22 Supported on-this frame of the die. -This section 22 is recessed, as at 23, and counter-recessed, as at-2et. This is held in place upon the face of the yoke 19' by means of a longitudinally movable rod 25, the forward end of which is reduced in diameter where it passes through the section 22 and is then formed with a up tightly against the face of the yoke 19 or moved outward from the face of the yoke 19. At the same time the die section 22 will move with the late 16, which in turn is movable upon t e rods 12, as before stated.

Coacting with the fixed die section 22 is a movable die section comprising a centrally disposed plate 33 and an outer plate 34:, the outer place being recessed or rabbeted at 'its margin and the central plate 33 being complementarily rabbeted so that the two plates, when placed together, are flush with each other. The plate 33 is held in engagement with the outer frame or plate 34 by means of the screws 35.

Attached to the outer plate 34 are longitudinally extending rods 36 which extend rearward from this plate 34, pass through the yoke 19 and through the plate 16. Two of these rods, which I have designated 37, have rack teeth upon their under faces and are engaged by the gear wheels 38, which in turn are mounted upon the shaft 20. By turning this shaft 20 in one direction or the other, the die plate 33 may be drawn into coactive engagement with the die member 22, as shown in Figure 3, or shifted out into the position shown in Figures 1 and 2. This die plate 33 is formed with a centrally projecting hub 39, the base of which is surrounded by an annular groove 40, and it is to be noted at this point that this groove 40 has a diameter equal to the diameter of the counterb-ore 24, while the hub 39 has a diameter equal to the internal diameter of the recess 23 so that when the parts are drawn over to the position shown in Figure 3', this member 39 will. enter the socket 23 and fit closely therein. The hub 39 under these circumstances forms the inner wall of an annular recess formed by the .counterbore 24 and the inner wall, of course, of the annular recess 40. The rods 36 are reduced at their forward ends to pass through the bores in the annular plate 34 and are screw-threaded for the reception of nuts. This permits the member 34: to be readily removed in case it is desired from these rods.

For the purpose of moving the carriage 16 toward or from the Babbitt pot 15, I niount upon each bracket 41 the transverse shaft 42 having thereon the projecting handle 43. Extending downward from the shaft 42 adjacent its extremities are the arms 44. These arms are connected to links 45, which in turn extend upward and are pivotally connected to bifurcated cleats d6 having screw-threaded shanks which pass through the plate 16 and are held in place thereon by nuts, as shown in Figure 2. a It will be obvious now that by pulling down upon the lever or handle 43, the carriage composed of the plates 16, the yoke 19, the die section 22 and the die section will move forward toward the Babbitt pot, and upon a movement of the handle or lever 13 back to the position shown in Figure 1, all of these parts will be retracted.

For the purpose of holding a connecting rod such as shown in Figure 4c in position where the eye of the connecting rod which engages with the usual crank shaft may be babbitted, I mount upon the plate 16 and above the section 22 a guide 47. Thisguide is arcuate in transverse section and projects outward beyond the extremity of the member 22 and, as illustrated in Figure 4, is provided with the two, vertical openings or bores 48. Oscillatably mounted upon the plate 16 above this guide 47 is 'a cam 49 which is pivoted eccentrically upon a bolt or other pivot member 50, this cam being formed with the cam track 51 and having.

projecting-therefrom the handle 52 whereby the cam may be oscillated in one direction or the other (see Figure 5)..

Operating within this cam track is a pin 53 which pro ects from an angular member 54, this angular member, as shown in Figure 4:, being provided with the downwardly projecting pins 56. These pins are adapted to extend through the bores or openings for the bolts normally used to connect the two sections a and Z) of the connecting rodbearing. This connecting rod, which is designated A, will be formed all in one piece, that is the section a; will not be separated from the section I), or in other words will not be cut through as yet and thus the pins 56 will hold what may be termed the head end'of the connecting rod firmly in place when the pins 56 are passed through these openings which are cast in the head of'the connecting rod for the passage of the usual bolts. By operating the lever 52, as shown in Figure 3,

the pins 56 may be drawn upward out of these openings, and by turning the lever in the other direction the cam will force these pins down into the head of the connecting rod.- As will be seen, the cam track 51 is so eccentric that a considerable range of the adjacent Wall movement can be secured for. this member 54 which carries the pin 56 and thus connecting rods smaller sizes may be readily engaged. The melting pot 15, as shown in Figure 2, has a central web 57 extending inward from of the melting pot, this web terminating in an enlargement 58 wherein is formed the vertically extending chamber 59. This chamber has an opening 60 in one wall thereof which opens into the melting pot, while the opposite wall of the chamber below the opening 60 is formed with a relatively small discharge passage 61 which, as shown in Figure 3, extends upward and then outward through a nozzle 64 formed in the wall of the melting pot.- This nozzle 64 is tapered at its extremity so that this shaft 69 being itfits into the mouth of a 'sprue-opening 65 which extends into the annular recess 40, as

shown in Figure 3. 4

Operating within the cylindrical chamber 59 is a plunger (36 by which the molten metal is forced out through the passage 61 into and through. the sprue opening, this plun ger 66 at its upper end being toothed, as at 67, and being engaged by a pinion 68 mounted upon a shaft 69 carried by a bracket 70, provided with a handle 71-. The bracket is apertured for the passage of the rack bar '72, this rack bar being separate from the plunger 66 and being engaged therewith by means of a union or collar 7 The lowerend of the chamber 59 is formed with an opening closed by a plug 74, and below this chamber there is provided means 75, designated in I dotted lines in Figure 3, whereby the Babbitt pot mav beheated.

The Babbittmetal pot is rigidly bolted to the frame bars of the machine but the can riage is movable along the rails 12, and in order to support the forward end, of the yoke 19 and prevent any possible chance of his yoke sagging downwardly, Iprovide a brace 76 projecting from the yoke at one or both ends, this brace carrying upon ita roller 77 which rolls along the adjacent rail 12. v

In order to hold the lower end of the connecting rod A, 1 form in the plate 16 the slot 78, and passing through this slot is a pin 79, the rear end of which is reduced in thickness and screw-threaded, as at 80, for the reception of a nut 81. A washer 82 bears against the wall of the slot and the nut bears against this washer. This pin 79 is adapted to pass through the eye 0 at the lower end of the connecting rod, as shown in Figure 3,,and the pin is supported in its adjusted position against any downward movement b r formin the in 7 9 with a rectan ular i z: e:

enlargement or shank- 83, as it may. becalled, which is engaged by a screw 84 having swiveled engagement with this enlargement having heads of larger or" 83 and passing through a screw-threaded fixed nut 85 mounted upon the plate 16 by means of the screw-threaded shank and nut 86. The slot 78 permits this pin 79'to be adjusted toward or from the center of the die section 22 and the square end of the shank portion 83 holds the bearing or eye. '0 at the lower end of the connecting rod in the proper vertical plane. The pin 79 is adjusted vertically within the slot by screwing upor down upon the adjusting screw 84, audit is obvious that by taking off the nut 81 other pinsmay be substituted for any one pin, thus adapting the device to be used with connecting rods having bearings of dilferent sizes. The same is true with regard to the die sections 22 and 33, which may be changed andvaried so as to suit connecting rods having ings.

In the operation of this mechanism, the babbitt is, of course, supposed to be in a molten condition, and before the connecting rod is put in place the piston 66 is raised, as illustrated in Figure 1, so that the charm different sized bear of the pot and metal will flow from the pot into this chamber 59. The passage 61, it will be seen, is at a height somewhat above that of the opening 60 and this passage is so constructed that the metal will not flow-out through the passage until this plunger 66 is depressed, when the metal will be forced out through this passage 61 and spurt'ed into the hearing. If it be desired to properly babbitt a connecting rod of the form shown in Figure 4, which connecting rod be it under: stood has-not yet had its bearing divided into two sections, the connecting rod is dis posed with its lower bearing upon the pin 79 and is then disposed with its upper bearing against the end of the die section 22.

The cam 49 is'then turned to cause the depression of the pins 48 through the apertures in the member 47-and into the apertures for the passage of the bolts through the upper bearing of theconnecting rod, as shown in Figure This looks the connecting rod in the position shown in Figure 3 so that one end of the upper bearing forms the wall for the recess 24. The handle or lever 43 is then turned from the position shown in Figure 1 to that shown in Figure 3, which shifts the carriage longitudinally along the rails 12 and forces the bearing into the position shown in Figure 3 against the die plate 33 and the hub of this die plate through the bearing. At this'time a stop 87 which is adjustably engaged with a support 88 (see Figure 3) limits the downward movement of the lever 43 and the parts are, therefore, projected to the full extend of the the nozzle 64,- but if it does not do this and there is need ofa further adjustment, which is, of course, requisite to accommodate the various thicknesses of connect-ingrods, this adjustment can be secured by turning the mits the machine to compensate or variations in the size of the connecting rod.

After theconnecting rod has been brought into proper position, the handle 52 is operated to cause the pins 48 to be forced downward into the head of the connecting rod, "as shown in Figure 4, and thus holdthe connecting rod from any turning movement. The plunger 66 is then depressed by means of the handle 71 and the molten liquid forced out into the space between the hub 29 and the yoke of the connecting rod, as shown in Figure l. \Vhen this plunger 66 is retracted, it will be noticed from F igure 1 that the plunger moves up above the opening 60. and permits passage of molten liquid through this opening into the cham ber 59, but when the plunger moves downward it cuts off this flow of liquid. The collar 7 3, it will be seen, acts as a stop preventing the too great depression of the plunger, and this collar v7 3 is so disposed relative to the length of the plunger, or the plunger 66 is of such length, that when the collar 63 is depressed so as to strike the upper end of the melting pot, just enough Babbitt metal will have been discharged to form the ordinary bearing.

In Figures 8 to 11, I show another form of my invention which is particularly adapted for casting a half bearing and in which the adjustment of the dies toward and from each other and toward and from the pot of Babbitt metal is secured by other means than that described. This mechanism is also 'mounted in a rectangular frame, as previously described, and as the construction of the Babbitt pot is exactly the same as in the apparatus shown in Figure 3, the same reference numerals have been used for this part of the mechanism. A carriage is pmvided as 'of practically the same construction as heretofore descrlbed, th1s carriage consisting of a back plate 16 sliding upon guide bars 12. A'voke 19 is mounted upon each side of the carriage are the guide and operating rods 95 which are toothed, as at 96, for engagement by the pinion 97 mounted upon'a shaft 98.

These parts are practically the same as the parts previously described for drawing the front die toward the rear die and illustrated in Figure 2' The die 23 is slightly I differently constructedf as shown in Figures 9 and 10, from the die 33. The. hub 39 of this die carries laterally projecting wings 99 which are apertured for the passage of bolts 100, which bolts are adapted to pass through the half bearing a formed upon the connecting rod a (see Figure 9). These wings 99, of course, form dams and extend into slots in the hub 39*. WVhen the molten metal is forced through the nozzle and through the aperture in the plate .3, it fills all the space between the core,vwings and the inner face of the bearing 12', as shown in Figure 9. The lower portion of the bearing may be made ata different time with this apparatus, this lower section of the bearing, which would correspond to the section a in Figure 4, being disposed in place of the section b, as shown in Figures 8 and 9.

The operationof the mechanism is precisely the same as it was before. The two sections of the die are separated by operating the shaft 98 and then the connecting ,rod is inserted in place and the sections drawn up together to the position shown in Figure 8. When this has been done the wheel 93 is operated to cause the carriage to travel forward until the nozzle 64* enters the opening. in the plate 33 and the piston ()6 is depressed by the mechanism'heretofore. described and the molten metal driven into the bearing. The carriage is then retracted, the two mold sections separated, and the yoke removed.

It will be seen that when the yoke is disjposed upon the wings 99, bolts 100 are passed through these wings and through the bearing, as shown in Figure 9, to thus hold the bearing rigidly in place. I have illus trated the plate 33 and the plate 33 1as being "'formed with only one sprue opening through which metal is disposed into the interior of the yoke, but obviously two or more sprue openings might be used for this purpose.

The reason for using the construction shown in Figures 8 and 9 for the purpose of casting the Babbitt metal for half bearings is that these bearings are usually large and it is impossible to cast the whole bearing at one time, as there is liability of the metal chilling before the interior of the connecting rod hearing has been filled with Babbitt metal. The casting of a bearing in two sections .at dilferent times, as disclosed in FiguresS and 9, is of particular advantage where there is a vcry'large connecting rod which takes a bearing requiring several times the quantity of Babbitt metal that some of the smaller rods take, thus creating a danger of the babbitt becoming chilled before it is thoroughly distributed over the rod. ,Of course, it would be possible to heat the connecting rod so as to prevent any chilling of the metal, but this is not expedient and would require additional op erating expense.

While I have illustrated a form of my invention which I have found to be very successful in actual operation, I do not wish to be limited thereto as it is obvious that the device might be embodied in other forms than that shown and that the mechanism is, therefore, susceptible to considerable variation over what I have illustrated.
