THOMAS F. BURGESS, 'OF LOWELL, MASSACHUSETTS.

Letters Patent No. 71,849, elated December 10, 1367.

IMPROVEMENT IN JOURNAL-BOXES- TO ALL WHOM IT MAY CONCERN:

Be it known that I, THOMAS F. BURGESS, of Lowell, in the county of Middlesex, and State of Massachusetts, have invented new and useful Improvements in Journal-Boxes; and-I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

a. The nature of my invention consists in so constructing the outside of thebox, that when placed in its receptacle or hanger, its bearing surface'will be around its centre, so that it will adapt itself to thejourual ,ot' the shaft freely when in motion. It also relates to the device for receiving and discharging the excess and waste lubricating-fluids that are not required by the journal.

v To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 1 represents avertical section of the cap to the box.

Figure 2 represents a vertical section of the box.

Figure 3 represents a plan of the box.

Figure 4 represents an end elevation of the box.

Similar letters in the difl'erent figures indicate corresponding parts.

In the jcurnal boxes now used no provision has been made to receive and carry off the cxcessor waste lubricating-fluids which are always attendant in the lubricating of bearings. The excess of oils in lubricating oozes out at the extreme end of the boxes, a part running down on the ends of the box, a part is caught up by the revolving shaft and collar, if any, and by the velocity of the shaft is thrown ofi', oftentimes to the great discomfort of the operatives} and damage to the work which may be located near. The part which runs down on the box usually spreads and runs over the entire surface of the under, part of the box, thence on to the hanger or box-receptacle until it finds its lowest point; it then drops into an oil-cup, thus rendering the box and hanger filthy and unclean. "And further, the under surface of boxes which areustraight, and bear their entire length, arearbitrary and unyielding to the demand ofthe' journal, shouldthesame revolve or run untrue; this causes oftentimes the shaft and bolts to break, and loss of power. I

i In my improved device these serious dii'liculties are obviated and remedied as'follows: The box a being made and lined in the usual way, a semicircular recess is formed in each end of the box at, indicated by the letters b 6, outside of the bearings c 0. Through these recesses b b, suitableconducting-holcs d d are made, which connectwith the drips e e. Contiguous and adjoining the recesses 6 b are the rims ff, whose diameters are finished larger than the bearings c c. The cap g is lined, and nrovided with recesses lab and rims ff to correspond with the box a. v I

The box a being placed in position, the journal of the shaft in the bearings ec,the cap g secured to the box a, and shaft in motion, the operator applies the oil to the shaft through the oil-holes h h in the cap g, the excess of fluid oozes out of the bearings at each end on to the shaft, where it is caught in the recesses b b, and prevented from extending and running further by the rims This waste fluid then descends and runs through the holes old on to the drips e e, where it is conveyed into the required oil-cups, thus preventing the shaft, hangers, and boxes from becoming filthy and unclean, and the work and surroundings from becoming damaged, also retaining and securing all the waste oil from loss. At the same time, by the convex form of the under surface of the box a, as seen in figs. 2 and 3, at s, the box a is enabled to adapt and adjust itselfnaturally and easily to the irregularities and untrueness of the shaft.

I disclaim a pivoted box, as they are already in common use; but

What-I-do claim as my invention, and desire to secure by Letters Patent, is-

The drips e e and conducting-holes d d, in combination with the recesses 12 b, when arranged to operate substantially as describedand for the purposes fully set forth.

THOMAS F. BURGESS.
