Patented March 9, 1909.

v Application filed October 21, 1908. Eerial No. 458,830.

T o @Il whom 'it may concern:

Be it known that I, lilnnnnnion Vf. SAL- MON, of Burlington, in the county of Des Moines' and State of Iowa, have invented cert-ain new and useful Improvements in Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains l of oil to find its way between the Babbitt to make and use the saine.v

'This invention relates to improvements in beai'ings and more articularly to cooling meansytherefor, the o ject of the invention being to locate and secure a cooling coil within a bearing in such manner as to render it impossible l'or a heating insulating iihn oi oil to get between the Babbitt metal in the begring md the water cooled surface 'of the co1 Y With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure i is a view illustrating the application of m invention, and Fig. 2 yis an enlarged detail view showing the location of the coolinr coil within the bearin f, the Babbitt meta `being broken away to s ow the coil. i represents a base from which a standard 2 rises, andthe latter is recessed forvthe relception oi' bearing boxes 3, 4. These boxes cooperate to form/ a shaft bearing and the upper box 4 is enlarged and forms a cap' 5 which is secured to the top of the standard 2. My improved cooling means are located in the lower box or -halfbearing 3 andin constructing the same, I proceed as follows: The interior oi the box 3 is rovided with a recess in which is iitted a coi 6, preferably of thin copper tubing having its exterior tinned. The recess inbox 3 is of greater depth than the diameter ol' the tubing so that when the coil is placed within said recess, there will be sufficient space over the same to receive the Babbitt metal lining 10 of the box. After the coil has been placed into position, the Babbitt metal will be poured into the boxand will become soldered to the tinned copper tubing. By causing such an intimate relation between the Babbitt metal and the tubing which forms the coil, it will be impossible for any heat-insulating film metal lining of the box and the water cooled rsurface afforded by the coil.

The respective ends of the coil G project through the bearing box 3 and also through suitable openings 7 in the standard 2 and are connected with pipes i8, 9, for establishing circulation of water through the coil from an convenient source of supply.y

blight changes might be made in the form and construction of the details shown in the drawings without departing from the spirit of my invention or limiting its scope, and hence I do not wish to restrict myself to such details.

Having fully described my invention what -I claim as new and desireto secure by Letters Patent, is,-

1. The combination with a bearing box member having a recess therein,lof a cooling '-coil located within said recess and Babbitt `metal covering said coil and united thereto.

2. The combination with a bearing box member havin(r arecess therein, of a cooling coil within sair. recess, said cooling coil consisting Ioi' co per tubing having its exterior tinned, and abbitt metal covering said coil and soldered thereto.

In testimony whereof, I have signed this specification in 'the presence of two subscribing witnesses. l
