BABBITTING MACHINE.

Appication led March 5, 1920. Serial No. 363,447.

T o all whom t may concern.'

Be it known that I, CHARLES W. EGGEN- 'WniLnrn 'a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Babbitting Machines, of which the following is a specification, reference being had therein to the accompan ing drawings.

The invention relates to abbitting machines adapted for use particularly in babbittin hollw backs of bearings. One ob,- ject o the invention is to provide means for revolving the hollow bearing back while the molten babbitt is being fed thereinto. Another object is to provide means for forcibly feeding the molten babbitt into the hollow bearing back. A further object is the prey vision of means for suddenly cooling the babbitt after the samevhas been fed into the bearing back to prevent separation of the elements comprising the babbitt whereby the density thereof remains uniform throughout and furthermore the rate of production is greatly increased. l

The invention has among other objects: The provision of a carrier having a plurality of holders for the bearing backs ;-fthe provision of means for rotating this carrier by a step-by-step motion; they provision of means for permitting of the ready removal and replacement of the bearing backs; and also the provis'ouof means for permitting of babbitting bearing backs of diferent lengths and diameters. Still other objects of the invention reside in the novel arrange ments and combinations of parts as more fully hereinafter forth.

in the drawings:

ligure 1 is perspective view of a ma' chine embodying my invention;

Figure 2 is a top plan view thereof;

Figure ZS is a vertical central section, partly in elevation;

'Figure 4 is a secticual elevation, showing the guards;

igure is a cross section on the line 5-5 of i igure 3;

i igure 6 is a cross section on the line 6-6 of Figure 3; Figure Y is a side elevation of the retort and pump with part of the retort broken away.

1 is the base, and 2 and 3 are upright supports thereon, having the bosses 4 and 5 respectively. 6 is a shaft rotatably mounted in the bosses 4 and 5, and 7 and 8 are carriers non-rotatably mounted upon this shaft.

The carrier 7 has the hollow hub portion 7 and the end fianges 9 and 10 which terminate in the cylindrical flanges 11 and 12, respectively, engaging the shaft. The eylindrical flange 11 extends through the boss 5 and is threadedly engaged at its outer end by the nut 13. 14 and 15 are arms in continuation of the end flanges 9 and 10, respectively, the arms 14 having bosses 16 at their outer ends, and the arms 15 having bosses 18 and cup-shaped enlargements 19 at their outer ends. 20 are shafts rotatably engaging in the bosses 16 and 18 and carrying holders 21 for the hollow 'bearing backs 22. For the purpose of lubricating the shafts 2() passages 23 and 24 are providedextending from the hollow hub 7 to the bearings for the shafts through the reinforcing webs for the arms 14 and 15, respectively.

The bearing back holders. 21 each comprises the head 25 having the annular outwardly extending shoulder 26 for engaging the end of the bear'ng back. This head is removably secured to the rotary fan 27 by means of the screws 28. The rotary fan is in turn secured to the cylinder 29 by the bolts 30 and concentrically located thereon by means of the shoulders 31 engaging in the annular groove 82 in the fan. 33 is a hey rockable longitudinally within the cylinder 29 but non-rotatable, relative thereto. rlfhis key is pinned to the shaft 20. 34 is a suitable anti-friction bearing between the inner side of the key and the flange 35 which is upon the member 36 and limits the outward movement of the cylinder relative to the shaft. The cylinder 29 is longitudinally, movable within the, cup-si'iaped inember 19. For yieldably holding the head 25 in its outward pos'tion the coil spring 38 is provided abutting against the ciip-i-ilmped member 19 und against the flange 535 the member 36. rllhe arrangement is such that the head 25 can be rocked to engage he'end of the bearing hack 22 throughout its entire extent, thereby sealing the saine.

The carrier 8 has the hollow huh 39 limi which has the end flanges 40 and 41 terminating in the cylindrical flanges 42 and 43, respectively. The cylindrical flange 42 is liXedly secured to the shaft 6 as by a set screw, this shaft being in turn prevented from longitudinal movement relative to the support 2 as by the shoulder 44 and nut 44 engaging opposite ends of the hub 4. 45 is an outwardly extending annular flange in continuation of the end flange 41, this flange being provided with the apertures 4G in axial alignment with the shafts 20. 47 are holders for the bearing backs 2&2 cooperating with the holders each comprises the head 48 located concentrically with respect to the axis of the aperture and having the annular shoulders 497.*for engaging the end of the bearing back, and also comprises the member 50 carrying the head 49 and having the hub portion 5l extending through the aperture. 'llhis hub has an inwardly extending flange 50 which is surrounded by the head 48. rlhis hub also has the conical surface 52 which is engaged by a suitable anti-friction bearing 53 mounted in the flange 45 whereby ythe member 50 may be rocked through an angle, so that its head 48 will engage the end of the bearing back 22 throughout iis entire extent and seal the same. 54 is a bushing threadedly engaging the outer end of the hub 5l and having the flange 55 for engaging the outer face ot the flange thereby securing the holder 47 to the flange llior the purpose ot' rotating the heads the motor 56 is provided mounted upon the lateral extension 57 of the support 3, this motor having the driving pulleyr 58 mounted upon its shaft, which pulley engaged by the belt 59 passing over the pulleys (3() nonrotatably secured to the shafts E30, the pulleys all being normally in alignment. When the bearing backs 22 are in position between the cooperating heads 25 and 48 sutticient 'triction is produeed to rotate the heads ln order to rotate all of this series ot heads 48, regardless ot their position relatire to the support 2, the belt (il is provided extending around the annular channel men'ibers G2 secured upon the holders 47. lt will be noted that the belt 59 does not engage the pulley 6G nearest to the motor.

Il is a nozzle adapted te conduct molten babbitt into the bearing backs and (S4 is a suitable pump Jfor Ytorcing the molten babbitt from the retort 35 through the nozzle (S-l. This nozzle is located in substantial axial alignment with the shaft 20 when the latter is located between the shaft (i and the motor 56 and has its axis in the same horizontal. plane as the axis et' the shatt (i. llillien the shat 20 is in this position its pulley 5l) is out ot driving engagen'ient with the belt The linb 5l or" each of the inein-v bers titl earrying the 4@ has an inward asians@ ly tapering aperture 66 axially the-rethrough, for permitting of the passage ot the molten babbitt into the bearing back.

ln order to direct the molten babbitt against. the inner Wall of the bearing back the nozzle 63 has its end closed and has an aperture 67 in its lower surface for the discharge of the molten babbitt. Furthermore, the nozzle is longitudinally movable through the aperture 66 of the head 47 and into the bearing back, this being accomplished in the present instance by having the pump 64 and the nozzle 66 slidably mounted as a unit upon the guides 68 across the top of the retort. (lo. The handle 69 for the pump is employed to slide the pump and nozzle.

F or the purpose of rotating the carriers 7 and 8, the hand lever 70 is provided pivotally mounted upon the' support 3 and connected by the link 7l tothe radial arm 72 upon the hub member 78, which latter is rotatably mounted upon the cylindrical flange l1 of the carrier 7 and between the support 2l and the end flange 9 ot' the carrier. 74 is a lug upon the hub member 73 and carrying a suitable spring pressed detent member 75, which detent is engageable with teeth 7G upon the carrier 7 to rotate the latter in one direction. ln the present instance there are tour teeth so thatl toi each complete operation ot the hand lever 7() the carrier will be rotated one-fourth revolution. This carrier having a non-rotatable engagement with the sliai't 6, as shown in Figure 6 particularly, the shatt and con sequently the other carrier 8 will be correspondingly rotated, the arrangement being Such that thecooperating heads tor one of the bearing backs Will always be axially aligned with the nozzle t'or conducting the molten babbitt.

'llo permit of readily removing and replacing a bearing back, the rock arm 77 is provided having a roller 78 engageable with the inner face of the pulley which is in horizontal relation to the lshaft 6 and between the shaft and motor. rlhis rock arm is connected to the link 79 having a universal engagement with the radial lugs 80 upon the hub member 73, tie arrangement being such that at. the end of the quarter rotation ot the carriers, the pulley GO with its shaft 2() and head 25 will. be moved longitudinally away from the cooperating head 48. lWhen this occurs the babbitted bearing back can be removed and an unbalabitted bearing back inserted a't'te'r which by releasing the downward pull upon the hand lever the head 25 and other parts will resume their normal position and the heads will adjust themselves to the opposite ends et the bearing back and close the joints therebetween. Due to the fact that the head rinfolving the bearinglback and lieffl will also be rotated in this position vali the molten babbitt is forcibly fed into the bearing back.

The heads 25 and 48 may be readily removed and replaced to take care of bearing backs of diierent diameters. The series of heads 25 may also be moved toward or away from the series of heads 48 as a unit to take care of bearing backs of different lengths. As shown 8l is a threaded rod mounted on the base l and engaging the support 3, which latter is longitudinally slidably mounted thereon. 82 is a crank for rotating the rod 81 and adjusting the support upon the base. The shaft 6 is of Sufficient length to permit' of this adjustment.

For the purpose of protecting the operator of the machine, the carrier 8 has the arms or guards 83 extending radially outward from the hub 39 and between the heads 25 and 48 and the bearing backs, the arrangement being such that they are partially embraced by the arms or guards. A pan 84 is also provided removably resting upon the base l and having a stop 85 for limiting its inward movement, this pan being concave to embrace approximately the lower half of the carrier 8 with the heads 25 and 48 and the bearing backs.

ln order to suddenly cool the babbitt after it has been fed into the bearing backs the conduit 86-is provided below the shaft 6 and 'adapted to register with the apertures in the holders 47 when rotated in the direction indicated by the arrow in Figure 4 to this position. With this arrangement onequarter of a complete revolution of thc carriers takes place in moving each holder 4T from the position where it registers with the nozzle (i3 to the position where'it registersv with the conduit 86. This conduit conveys wat-er. the flow of which can be suitably controlled as by a valve (not shown). l/Vhen the water comes in Contact with the molten babbitt vapor or steam isformed which is withdrawn by means of the rotary fans 2? which communicate with the interior of the bearingvbacks through the axial apertures 87 and 88 respectively in the fans'and heads 25.

The purpose of conducting the water into the bearing back containing the molten metal is to solidify the latter before the elements comprising the same separate and those of greater specific gravity become arranged near the. outer surface of the bahbitt due to the centrifugal force caused by the rotation of the bearing back. This rotation uniformly distributes the molten babbitt about the bearing back. Another important consideration is that the rate of production s greatly increased due to the fact that the molten babbitt is solidified so uiclcly rel ative to the usual practice hereto ore.

The general operation of the machine is as "follows: the operator raises the hand lever to move the head 25 away from its cooperating head 48 the heads being at the front of the machine or between the shaft 6 and motor 56 and their axes in the horie zontal plane of the axis of the shaft. An unbabbitted bearingv back is inserted between the heads and the hand lever released, when the bearing back will revolve, the other heads clamping bearing backs. The nozzle' 63 is inserted into the bearing back and then a predetermined amount of molten babbitt is pumped through the nozzle against the interior wall of the bearing back. The carriers are rotated a quarter revolution when the bearing back containing the molten babbitt registers with the water conn duit and the molten babbitt is subjected to water. The fan 27 withdraws the vapor or steam created in the bearing back. Meanwhile another unbabbitted bearing back is being operated upon in the first position and in the same manner. These operations are continued for each partial revolution of the carriers.

For the purpose of controlling the amount of molten babbitt to be forced into the bearing back the stop 89 is provided for limiting the downward movement of the pump handle 69 and consequently the plunger actuated by the handle. This stop is adjustable to vary the amount of babbitt dependent upon the size of the bearing back being handled by the machine. Another important consideration is the arrangement of inlet openings into the pump cylinder, whereby the impurities and slag in the molten metalin the retort will not enter the cylinder and thus be forced into a bearing back. Specifically 90 are inlet openings in the periphery of the pump cylinder and in termediate its ends, these openings being a substantial distance below the surface of the molten metal', so that when the pump plunger is raised, pure molten metal will enter the cylinder.

While I have used the term babbitt in the specification it is to be understood that bearing-metal allo s other than Babbitt metal itself are inc uded.
