APPARATUS FOR LININ G BEARINGS.

Application filed March 12, 1928. Serial N0.'261,117.

The present invention relates to improvements in the art of rehnmg ]ournal bearings with babbitt and has for its principal object to provide an apparatus for efficiently carrying out this process. r

One of the important objects of the present invention is to provide an apparatus of the above mentioned character that employs compressed air, thereby saving considerable time and labor in relining journal bearings withbabbitt. I

A further object is to provide an apparatus of the above mentioned character, that will properly support the bearing in spaced relation with respect to the form, so that "the inner face of the bearing may be lined with the babbitt, there being no possibility'of the bearing shifting to either side, during the process of lining of the bearing.

Another important object of the invention is to provide an apparatus of the above mentioncd character, which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects of the invention will become apparent as the nature of the invention procceds and when taken in connection with the accompanying drawings. 7

Figure l is a rear elevation.

Figure 5 is a longitudinal sectional view through a swinging cylinder, and the plunger carrying piston rod associated therewith.

Figure 6 is a detail perspective view of one pair of sliding blocks or vanes, forming a salient part of the present invention.

Figure 7 is a detail perspective view of one of the slotted plates, on which the pair of opposed blocks or vanes are arranged for slidable movement, and

Figure 8 is a detail perspective view showing one-0f the slotted plates, with a vertical shaft j ournaled thereon.

In the drawings, wherein for the purpose of illustration is shown'the preferred embodiment of my invention, the numeral 1 designates a table of substantially rectangular shape, the supporting legs therefor being illustrated at 2. Secured on the tables are a pair of units designated generally by the numerals 3 and 4 respectively, and as each unit is of identical construction, the description of one is thought to sufiice for. the description of both.

Each unit includes a base plate 5, that is secured on the table by any appropriate fastening means shown at 6. Stationary form or mold 7 extends upwardly from the central portion of the base plate 5, and the front face of this mold or form is clearly illustrated in the drawing. The stationary form or mold is of such size as to be smaller than the bore 8 of a journal bearing 9, that is to be lined with babbitt, in the manner to be hereinafter more fully described.

Each unit further includes the provision of a pair of brackets 10 and 11 respectively, that are arranged vertically and rearwardly of the stationary form or mold 71 These brackets extend upwardly from a flat strip 12, that is secured to the table directly adjacent the rear edge of the base plate fastening means such as is shown at 13. Forwardly extending arms 14 are formed on the upper ends of these brackets 10 and 11 and the free ends of these arms are disposed downwardly as shown more clearly in Figure 2 for attachment to the rear face of the upper edge portion of the rectangular plate 15.

The lower portion of the plate is attached to the adjacent portion of the bracket by the cross pieces shown at 15, in Figure 2.

The plate 15 is spaced with respect to the rear flat face of a stationary form or mold 7, and a forwardly extending flange 17 is formed 5, by any appropriate on the lower edge of this plate to provide a support for the sliding block or vanes ass0- ciated with each unit and the construction and function ofthese sliding members will be hereinafter more fully described.

It will, be observed upon referring toFigure 7 of the drawings, that each plat-e 15 is formed with upper and lower longitudinally extending slots 18 and 19 respectively, and a central slot 20 is slightly out of alignment with respect to the upper and lower slots.

The complementary blocks or vanes that are associated with each unit are designated by the numerals 21 and 22, and the outer forward edges of these blocks are rounded, to conform to the contour of the inner curved face 8 of the bearing 9. These complementary blocks or vanes are interposed between the rear face of the stationary form or mold 7 and the stationary plate 15, and the lower edges of the blocks or vanes rest on the forwardly extending lateral flange 17, as is clearly shown in Figure 2 of the drawings.

Upper and lower apertured ears 23 and 24 respectively extend laterally from the inner side edge of each of these blocks as clearly I shown in Figure 6, the upper ears being arranged in alignment with the upper slot 18, while the lower apertured ears are 1n alignment with the lower slot 19 formed in the plate of each unit.

Vertical shaft is associated with the stationary plate 15 of each unit and the upper end of this shaft is journaled in a suitable bearing 26 formed on the front face of the plate 15, at the upper edge thereof. The

- lower end of this shaft is journaled in a suitable recess 27 formed in the flange 17. Upper and lower crank arms 28 and 29 respectively are arranged on the shaft 25, the forward ends of these crank arms protruding through the upper and lower slots 18 and 19 respectively. The upper crank arm 28 is operatively connected to the upper apertured cars 23 of the complementary blocks or vanes 21 and 22 respectively, through the medium of the links 30, one of the links being connected at its inner end to the forward end of the crank arm 28, while the inner end of the other link is connected to the opposite end of the crank arm, and this construction is more clearly disclosed in Figure 3 of the drawings.

The lower crank arm 29is operatively connected to the lower pair of apertured cars 24 in a similar manner, the lower links being designated by the numeral 31.

The cranks 28 and 29 cooperate with the links 30 and 31 and the apertured ears 23 and 24 of the pair of complementary vanes or blocks 21 and 22 respectively, to effect the sliding movement of said vanes in opposite directions as will be presently described.

A horizontal cylinder 32 is supported on the upper end of a vertical standard 33 that extends upwardly from the rear portion of the table 1, at a point intermediate the units 3 and 4, and extending longitudinally through this cylinder is the elongated piston rod 34, a piston 35 being carried by the intermediate portion of this rod for reciproeatory movement within the cylinder 32. A main air supply pipe 36 extends vertically at the central portion of the front of the cable and has communication at the lower end with any suitable source of-compressed air supply (not shown). A horizontally disposed air delivery pipe 37 extends transversely beneath the table 1 and communicates at its forward end with the supply pipe 36, by any appro priate fitting.

Branch pipes 38 and 39 have communication at their lower ends with the air delivery pipe 37, the upper ends of these branch pipes having communication with the respective ends of the stationary cylinder 32, as clearly shownin Figure 4. This construction provides a means whereby the piston 35 will be reciprocated in the cylinder. The outer ends of the piston rod 34 extend rearwardly of the stationary plates 15 of the respective units 3 and 4.

A pair of spaced fingers 40 extend laterally from the intermediate portion of each vertical shaft 25 and the outer ends of the elongated piston rod 34 are pivotally connected between the outer ends of these respective pairs of fingers, to provide a means whereby said shaft may be actuated simultaneously with the sliding movement of the piston rod to either retract or expand the sliding vanes or blocks. The fingers 40 extend rearwardlythrough the central slot 20 of each plate 15.

A vertical post 41 is mounted for vertical swinging movement at the front side of the table, one between the units 3 and 4, and extending between the lower end portion of this post is a compressed air delivery pipe section 42, that has communication with the supply pipe 36. This pipe section 42 afiords a means for supplying compressed air to the outer end of a cylinder 43, that is supported, in the upper end of the post 41, and the connecting pipe that extends between the out or end of the cylinder 43 and the pipe section 42 is shown at 44. It is of course to be understood that the pipe section 44 is connected to the pipe section 42, in such a manner as to permit the swinging movement of the pipe section 44, simultaneously with the swinging movement of the pivoted post 41 and this post is actuated by a handle 45, that extends upwardly from a bracket 46, the latter projecting from the intermediate portion of the post A multi-way valve 47 is arranged in the supply pipe 36, and as this valve may be of any well known construction, a detailed description thereof is not believed necessary.

A similar valve may be associated with the pipe 37 for controlling the flow of the compressed air to the branch pipes 38 and 39.

In Figure 5 of the drawings, there is shown the specific construction of the cylinder 43, that is supported in the upper end of the swinging post 41, and it will be observed that the ends of the cylinder are closed by the closures 48. An elongated piston rod 49 extends centrally through the closures and the cylinder and carried by the inner end of this piston rod is the plunger head 50 that is adapted to engage the outer front side of the bearing 9. A piston 51 is secured on the piston rod 49 for reciprocatory movement within the cylinder 43, by the action of the compressed air entering the outer end of the cylinder. A. knob 52 is carried by the outer or forward end of the piston rod for retracting the same manually. I

For the purpose ofgoverning the inward movement of the piston rod 49 and the plung er head 50, thereis provided an angular arm 53, that is operatively eonnected'to the outer end portion of the piston rod and the longer portion of this arm extends across the top of the cylinder 43, or rather across the top of the upper end of the swinging post 41, in a suitable channel provided therefor, a set screw 54 adjusting this arm.

Extending laterally from the brackets 10 and 11 of each unit are the arms 55, two of such arms being associated with each bracket and extending in an outward direction.

A headed pin 56 extends through a suitable opening provided therefor in each of these extensions 55. An expansible coil spring 57 encircles each headed pin 56, and this spring is disposed between the head 38 and the respective apertured extension 55, for normally urging the pins forwardly, and the purpose of these pins is to provide a means for bearing against the projecting ends of the bearing 9 to assure the application of a uniform pressure against the bearing, as the latter is being pressed into place or position with respect to the stationary form or mold 7, as will be now more fully described.

In operation, the bearing 9 is placed in an upright position on one of the units, in front of the stationary form or mold 7, The post 41 is then swung laterally or in proper position with respect to the unit that is to be used, and when in its proper position, air is admitted to the cylinder 43 and the same will force the piston 51 rearwardly in the cylinder 43, so that the piston rod 49 will move inwardly and as the head 50,is in engagement with the outer face of the front side of the bearing 9, said bearing will be forced rearwardly on the base plate 5 toward the stationary mold or form 7 Simultaneously, air will'be admitted to the cylinder 32, through the branch pipe 39 when the unit 3 is in use, so that the piston 35 will move toward the left, and this will result in the adjacent end of the piston rod 34 also moving in a left hand direction. By reason of the connection of the outer end of the piston rod 34 with the shaft 35, associated with unit 3, the shaft will actuate cranks 28 and 29.

This will effect an outward sliding movement of the complementary blocks or vanes 21 and 22, so that the curved faces of these vanes will engage with the curved inner face 8 of the bearing 9, thereby causing the bearing to be properly spaced with respect to the curved front face of the stationary form or mold 7 and leaving the correct space to receive the babbitt. The headed ends 58 of the spring pressed pins 56 will engage with the outer ends of the bearings 9, in the manner as shown in Figure 3, so that a uniform pres sure against the bearing is afforded.

When the parts are arranged as shown in Figure 3, the inner peripheral face of the bearing 9 may be properly lined with babbitt and the vanes or blocks 21 and 22 will prevent the babbitt from escaping beyond the respective side edges of the inner central face of the bearing.

By swinging the post 41 to the right hand side of the table, the unit 4 may be used in a like manner and the sliding vanes associated with the unit 4, are Controlled by admitting air to the cylinder 32 through the branch pipes 38, so that the piston 35 will travel in a right hand direction, whereby the vanes 21 and 22 will be caused to slide outwardly beyond the'sides of the stationary plates 15. When the operation has been completed, the

post 41 is returned to the position shown in Figure 1, and the bearing that is lined with the babbitt can be readily and easily removed from the table.

It will. thus be seen from the foregoing description that I have provided an apparatus for lining journal bearings with babbitt, which will at all times be positive and efficient in its operation, and by employing compressed air, considerable time and labor will be saved in carrying out that process of lining bearings with babbitt.

An apparatus of the above mentioned character can be readily and easily set up in position for use, and can also be disassembled whenever necessary.
