Application filed May 16,

To. all whom it may concern ,1

Be it known that I, EARL Lannm DAILY, a citizen of the: United States, residing at Mount lVashington, in the county of Jackson and, State of Missouri, have invented certain new and useful Improvements in Babbitting Jigs, of which the following-is a specification.

This invention relates to improvements in babbitting jigs and while it may be employed tov advantage in babbitting varis ousarticles, in the. drawings I haveshown it applied to a hearing such as constitutes a part of the cylinderbloclr of an engine.

Inits preferred form the invention embodies, among other features, a baseplate adapted to. fit directly upon the open flat side ofthebearing to be babl'aitted and having openings through which, the fluid babe. bitt may flow into the bearings, a die for placement within the bearing to mold'the fluid babbitt. to fit, or approximately fit, the shaft to be journaled in said bearing, means to grip and close the ends of thebearing, and prevent the fluid babbitt from fiowing from said ends, and a rotary hopper which performs the triple function oi? directing-themolten babbitt tothe gates of the base plate, shearing-ed the surplus metal, and releasing the gripping means from the ends of the hearing.

In order that the invention may be -fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is aplan View of the babbitting:

Fig. 21s. a side elevation partly n: section of the jig.

Fig. 3 is an irregularsection on line T11 of Fig; 1, and in addition showing the jig on a bearing to be babbitted,

Fig. a is a detail perspective view of a base plate constituting a portion of the Fig; 5: is an inverted plan viewof thejig.

Fig. 6 is a plan view of the jig in pfosi tion upon an inverted cylinder block.

Fig. 7 is a vertical section of thejig,

Tn carrying out the invention, I employ a hopper-2 havinga central vertical partition l dividing said hopper into two compartments 6, which taper downwardly to parallel gates 8 spaced apart and extending through the bottom of said hopper E2.

The hopper 2 is provided. with a pair of 1921. Serial No. 469,795.

oppositely-disposed bosses, 10, equippediwith handles 12 whereby the hoppermay be r04 tated upon a central axis consisting: in the; present instance of a stud 13 extending; through the. partition 4:, the; base plate la and a die 16 into which said stud. 13- is. threaded. Suitable means such flSrlOCk' nuts 18 are threaded uponthe upper end of the stud 13. to retain thehopper 2, the base plate 14 and the: die 16 is. assembled posh tion. 1

The base plate 14 which lSml-IllZQI'PQSGd; between the bottom of the hopper 2, and? the. upper portion of the die 16, has a pair 0t parallel gates 20 which are spacedapartto register with the gates 8 in the. hopper when the latter is rotated to the position disclosed by Figs. 1 and 2. Two. dowels,

22 project from the underside of the base plate 14 to enter the bolt holesA in the bearing B, for the purpose-of properly posi-v tioning the jig upon said.- bearing.

The die 16 is thesame, or approximately the same, diameter as: theshaft to be: journaled in the bearing 13, after the latter has beenbabbitted, but, its upper halfis: cut away to receive thebase plate 14: and

the lower portion of the; hopper 2, so that when said base, plate let rests upon. the bean ing 13 only the lower half; of the die 16 will project into said bearing. When the die 16' is in position in the bearing-e13, aq space 0 is left between the outer curved surface of said. die and the inner surface of the bearingto receive the fluid bahbitt which is to form the lining of the; hearing The fluid babbitt is prevented from es-i caping at the ends, of the bearing B by a pair of sleeves 24:, which engage and close the ends of said bearing as disclosed by Fig. 3. The sleeves 2 1- are yieldab j'y held in engagement with the ends of thew-bearing B by coil springs 26 interposed: betweencollars 28 and the adjacent ends of the sleeves 2 1. The collars 28 are secured to the ends of the die 16 by; suitable means such as screws 30, so that they may be placed in position after the springs; 26 have been placed upon the die16.

The sleeves 24: are provided at their upper portionswith antifriction rollers 32, which are forced in opposite directions to disengage the sleeves 2% from the ends of the bearing B by diametrically opposed cams 34 formed integral with or otherwise fixed tothe hopper 2. The cams 341; have concentric surfaces 36 struck from the axis of the stud l3 and provided with recesses 38 to receive andhold the rollers 32 stationary, so that they in turn will hold the sleeves 24 in their outermost positions against the action of the springs 26 and allow the jig to be either placed in position or removed from the bearing B.

In practice the sleeves 2e are forced apart to readily passover the ends of the bearing B by grasping the handles 12 and rotating the hopper 2 on the stud 13 until the recesses 38 receive'the rollers 32. The jig is then placed in position uponthe bearing B where it is properly located by the dowel pins 22 entering the holes A. The hopper 2 is then rotated in a reverse direction to bring its gates 8 into register with the gates 20 in the base plate 14:, Figs. 1, 2 and 3, and to allow the Springs 26 to force the sleeves 2 L firmly into engagement withthe ends of the hearing B. When the gates 8 register with the gates 20 further-rotation of the hopper 2 is checked by a shoulder 4:0 on said hopper contacting a stop 42 projecting upwardly from one corner of the base plate 14. The

fluid babbitt is then poured into the two compartments 6 of the hopper 2,preferably, with a two-spout ladle and flows into the space C, filling the same. The hopper is then rotated to the initial position to perform the dual function of shearing off the surplus material above the gates 20 and spreading the sleeves 24E apart to disengage them from the ends of the bearing B, so that the jig can be easily lifted from said hearing. The entire operation is performed in a very short time and good linings are insured as the fluid babbitt has no time to congeal before filling the space C.

While I have shown and described the preferred form of my babbitting jig, I reserve the right to make such changes in the construction, combination and arrangement of parts, as properly fall within the spirit and scope of the'appended claims.

Having thus described my invention, what I claim and desire, to secure by Letters Patent, is:

In a bearing babbitting device, a base plate adapted to rest upon a bearing and having two gates spaced apart, a die se cured to the underside of said base plate at a point between the gates and adapted to extend into the bearing to be babbitted, and rotatable means associated with the base plate to direct the fluid babbitt through the gates and shearofi the surplus babbitt.

2. In a bearing babbitting device, a member adapted to rest against a bearing and having an opening for the passage of fluid babbitt into said bearing, a die associated iwith said member and arranged to extend having an opening for the passage of fluid babbitt into said bearing, a die-associated with said member and arranged to extend into the bearing to mold the fluid babbitt, elements adjustably mounted on said die to engage and close the ends of the bearing,

springs to yieldably hold said elements in engagement with the ends of the bearing, and rotatable means associated with the member to direct the fluid babbitt through the gate and shear ofl the surplus babbitt.
