earerrr BABBiETTING MACHINE.

To all whom 2'15 mag concern Be it known that 1, AUGUST Er c PEARSON, a citizen of the United States of America, and a resident of the city oi Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and use ful Improvements inv Babbitting Machines, of which the following is the specification.

My invention. relates to improvements in babbitting machines, and the object of the invent on is to devise a simple device for babbitting such articles as bearing caps and such as may be readily adaptable for po n ing the metal under varying conditions, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. l is a. front elevation of my babbitting machine.

Fig.2 is a plan view of my machine Fig. 3 is a side elevation of my machine.

Fig. l is a front elevation of the base casting, andswinging support carried by-the base casting.

Fig. 5 is a plan sectional view, .the left hand side showing the cap to be babbitted in position, and the right hand sideot the view showing the parts with the cap removed.

Fig. 6 is across sectional view through Fig. 1, taken on line 66 and looking in the direction of arrow.

Fig. 7 is an enlarged sectional detail through the bearing cap, mandril and end blocks showing the babbitt poured into the cap.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates the base casting which com-v prises a. base piece 2 from which extend

vertical standards

3 and 4. At the top of these standards is located an orifice 5. 6 is Y an arm extendlng rearwardly from each standard 3 and 4c, such arm being provided with a slot 7 the arm and slot being curved comprises a base plate 9 inwhich is located.

the recesslO forming the bed for the mandril as, hereinafter described, and. with side. guides 11 for a purpose which will here-- inafter appear. y

The mandril supporting member also comprises lugs 12 which extend upward from each. side of the base plate 9 at theinside of Application filed November 26, 1921. Serial No. 517,938.

each. standard 3 and l. The lugs 12 are also provided with orifices 13 through which and each orifice 5 extends a bolt 14 thereby pivotally supporting themandril base upon the standards 3 and l. 15 are a'ms which extend from the base plate 9 at each side thereofclosely adjacent to the arms 6 and sinilar in form to such arms.

i6 are wing nuts which are screwed into orifices formed in the arms 15 and extend through the slot 7 so as to clamp ea h pair 0]?

arms

15 and 6. together. i

The base plate 9 is also provided with a pair of. horizontally d sposed lugs 17 and. 1:8, a pair of

lugs

17 and 18 being disposed at each side of the base plate 9. .ilach portion or the mandril support forming the guide ways ll is cut away intermediately of its length as indicated at 19, see Fig. i, so as to leave an opening 20 located between the base plate .9 and each standard and 4.

21 are arms which are swun between the extending through the bat-l: of the manoril support 9. 24; is-the m-andril proper which is. n the form or a semi-cyiindrical body socured to, or formed integral with the base 22. 25 is a groove formed in the outer face of the inandril 24 at its upper end, the upper portion being flared outward as indicated at 26 so as to receive the molten babbitt which is poured into the groove.

28 is a bearing cap of usual construction provided with the bosses 29 having bolt orifices 30. 31 are orifices formed in the mandrilbase 22 in aline with the orifices 30. 95

The bearing cap 28 fits around the mandril 24 so as to leave a space to receive the babbitt.

32 and 33 are blocks which are similar in form to the bearing cap 28 but considerably

10o

36 and 37 are semi-circular recesses formed 105 in the

blocks

32 and 33 into which the babbitt enters when poured so as to form What is known as the fillet.

36 and 37 are semi-circular grooves formed concentric to the aforesaid recesses 110 36 and 37 The inner edge of each groove is substantially flush with the outer diameter of the bearing cap 28.

These grooves are filled with a fibrous substance such as asbestos wool, this wool overhanging the division between the cap 28 and the.

blocks

32 and 33 so as to prevent theleakage of babbitt. V

38 and 39 are rods each of which are provided at one end with a handle 40 and at its opposite or inner end with an inturned por: tion 41 which passes through the orifices 3O and'31. The inturned portion 41 is provided with an enlargement 42 which bears against the top of the boss 29 of the cap 28.

43 and 44 are levers which are pivotally carried upon the ends of the turned portions of the arms 21.. The inner or operative ends of the levers bear against the enlargements 42 and are located between the standards 4 and 5 and therods38 and 39. i

45 are levers pivoted between the lugs 46 carried by the mandril support 8. The handle of each of these levers is spring held outward by a spiral spring 47. The opposite ends'of the levers 45 extend in the operative position over the

rods

38 and 39 to lock the inturned ends of the rods in the orifices 30 and 31.

The mandril support 8 is provided with a foot plate 48 from which extend hollow bosses 49 and 50 in which are held spiral springs 51. The springs 51 bear against the lower end of the block 33 forming a support for the same.

52Yis a pull rod which extends through an orifice formed in the foot plate 48 and is secured at its upper end in the block 33. The pull rod 52 is operated either manually or by any other suitable form of'foot mechanism.

Having described the principal parts involved in my invention, I will briefly describe the operation of the same.

When it is desired to babbitt a cap, the block 32 is lifted upward so that the flanges 34 slide out of the guide ways 11, thereby removing the block.

After this has been done, the wing nuts 16 are loosened and the mandril support swung to a horizontal position, the wing nuts being then again tightened so'as to hold the mandril 24 and its support in a horizontal position ready to receive a bearing cap. As the mandrilsupport is swung to a horizontal position the arms 21 are freed so that they swing outward upon their pivot carrying the

levers

43 and 44 outward and downward clear of the mandril and its support.

In order to place the cap 28 in position, the

rods

38 and 39 are inserted in the orifices 30 of the cap, and the cap lifted by means of the

rods

38 and 39 into position upon the upper endof theblock 33 so as to fit around the mandril 24 and against the outer face of the the levers 45. It will be noted that each of the levers 45 is provided with a curved outer end 45*. As the

rods

38 and 39 are swung beneath the levers 45 they engage the curved portions 45 so as'to force the levers 45 outward against the pressure of the springs 47 as the

rods

38 and 39 enter beneath the levers.

The block 32 is then replaced and the grooves 36 and 37 X filled with asbestos fibre so as to pack the joints between the

blocks

32 and 33 and the cap 28. If the cap 28is provided with oil holes or like orifices, the babbitt may be poured through these when the cap is in the horizontal position above described. If however it is necessary to pour the babbitt into the cap "endw'ise, the wing nuts'16 are again released and the mandril support swung either to a vertical position orv an angular'position, the angle being decided upon according to the conditions and by actual test.

When the cap has been placed in position as before described, the molten babbitt is then poured into the groove 25 flowing from thence into space between the cap andthe mandril and into the

recesses

36 and 37.

In order to remove the cap after it has been babbitted, the block 32 is first removed then the

rods

38 and 39, the block 33 forced downward and the

levers

43 and 44 brought.

as it is then necessary to withdraw the block 33 so as to carry the lower fillet out of the recess 37 before the cap can be lifted.

From this description it will be seen that I have devised a very simple form of babbitting machine which is adaptable for use under all circumstances and conditions found in babbitting of caps and like articles.

What I claim as my invention is:

. 1. In a babbitting machine, a mandril sup ported upon a suitable structure, guideways located in each side of the mandril, a resiliently supported lower block engaging the lower end of the mandril and slidable within the guideways, an upper block also freely slidable within the guideways and restin upon the upper end of the bearing cap, an a lever support for the cap adapted to eject the cap and upper block from the guideways when the lower block is withdrawn against The rods the pressure of the resilient supporting means.

2. A babbitting machine comprising a base forming a mandril support, a se1nicylindrical mandril carried by the base, guide Ways located at each side of the man dril, a block slidably held in the guide ways and adapted to bear against each end of the cap when in position surrounding the mandril, a pair of rods each having an inturned end adapted to fit into a bolt orifice of the cap, a pivoted spring pressed lever, having an outturned end pivotally carried upon the mandril support and adapted to extend over the rods when in their operative position.

3. A babbitting machine comprising a base provided. with side standards having bearing orifices at their upper ends and arms extending from the standards and having slots therein concentric with the centres of each orifice, a mandril support provided with lugs, pivot bolts extending through the orifices of the standards and the lugs, arms car- &

ried by the mandril support, a locking bolt extending through each of the aforesaid slots into the arms of the mandril support, a semi-cylindrical mandril carried by the support having a babbitt pouring groove at its upper end, guide Ways located at each side of the mandril support, blocks slidably carried in the guide ways and adapted to bear against each end of the cap when in position around the mandril, swinging arms carried by the man dril support at each side, ejecting levers carried by the arms, rods having inturned ends entering the bolt orifices of the cap and each having an enlargement bearing against the corresponding boss of the cap, and against which the operative ends of the levers are adapted to bear, a spring pressed locking lever carried by the mandril support and extending over each rod, and a yieldable support over the lowermost block.
