LUBBIGATING SYSTEM.-

Original application filed November 19,

To all whom it may concern:

Be it known that I, WILLIAM H. LIEBER, a

Waukee, in the county of Milwaukee and State of Wisconsin, have lnvented certain new and useful Improvements in Lubr1cating Systems, of which the following is a specification.

This invention relates to improvements in' lubricating systems and is particularly adapted to be used in connection with motor driven machinery in which the motor is mounted above the driven member.

The object of the invention. is to provide an eflicient and automatic lubricating system which will keep a constant circulation of lubricant to the various bearings of-a machine without the aid of special circulating P P This application is a division of an application for patent for motor compressor, Serial No. 463,401, filed Nov. 19, 1908.

A clear conception of the inventioncan be obtained by referring to the accompanying drawings in which like reference characters designate the same parts in different views.

F 1gure 1 is a central vertical'section of a motor driven compressor having the motor mounted above the compressor, and having the invention applied thereto. Fig. 2 is a plan of the device shown in Fig. 1. Fig. 3 is an end View of same.

The crank case 1, gear case, 2, and the cylinders 3, 4, are cast in one piece and: inclose the working parts of the compressor. The crank shaft 6. is supported in the crank case 1 by the bearing 7 at its front end, and the bearing 8 near its gear end, and lies .at

right angles to the cylinders 3, 4. The large.

openings 9, 10, under the bearings 8,7, respectively form a continuous basin for the oil 5 throughout the entire length of the crank case 1 and gear ease 2. The openings 21, 22, respectively,'above and below the continuous oil basin, form an admission and discharging means for the oil 5 therein. The crank case 1 and gear case 2 are castwith round bottoms, see Fig. 3, to give strength.

to the casting-and also to allowthe connecting rods, not shown to be more effective in throwing the oil 5 while sweeping there- Specification of Letters Patent.

The crank shaft 6, sup ings 7, 8, is held in place y suitablecaps 14, 15, which are provided'w-ith oil basins at their. tops; These oil basins have holes 17 passing from their lower portions to the bearings 7,'8 of"the crank shaft 6.' The cranks 18, 19, of the crank shaft 6 are 10- fcated directly in front of and in line with the openings of the cylinders 3, 4. Suitable.

connecting rods extend from the'cranks 18,

the cylinders 3,4. -The connecting rods,

wrist pins and pistons are not shown he cause their construction is wellknown 1n the art. See Christensen 635,280, Oct 17,1899. A suitable cylinder head 64, seeFigs. 2,-3, incloses thecylinders 3, 4, at their outerendf The end of'the crank shaftfi which is'nearest the bearing 8', carries -agear 11 which extends above the top of the gear case 2- and also down into the oil basin containing the oil 5.

The pump base 1 is provided with acover 23 which extends upto the gear case 2 and has an opening 24 passing therethrough.

This opening 24 serves as avent-for the-mterior of the crank case 1 and opens directly into the atmosphere. The shields 25 maybe provided to prevent any oil 5- from 'splash=;

g out due to the revolution of the 1 crank shaft 6. I

The. motor base 27 supporting the armature shaft 13, is mounted uponthe cover 23,

an air space-28 separating thetwo'. The ar; mature shaft '13 is supported upon the'motor base 27 by two bearings 29,30, which are'located directly above the oil pockets 31, 32,

respectively. 'The oil rings 33, 34, which.

are suspendedfrom the shaft 13, eartend j down into the pockets 31, 32, respect1vely,-'

the lower portions of these rings 33, 34, being immersed in the oil 5 withinthe pockets 31, 32. The pocket 32 has an opening 35 leading theretonear'the upper. portion of i the gear 11. -The rpocket 3l has an over flow 37 leading therefronnjwhich overflow 37 is directly in line with the basin on the top of the bearing cap 14. The two pockets '31, 32, are connected by a pipe 36 which ex 12 meshes with the gear 11, thus forming a driving connection between the armature shaft 13 and crank shaft 6. The bearing 30 at the gear end of the armature shaft 13 is provided with a cap 41, which cap also 7 parts of the motor.

' a portlon thereof will flow out of t forms a cover for the upper part of the gear 11 and the pinion 12.

The motor 1s inolosed by the motor base 27, the field frame 47, and the cover 55, the

latter being removable to allow for easy access to the brushes and other working The front oil thrower 63 prevents an oil from passing from the bearing 29 to t e commutator 54 and armature 26, while the rear oil thrower 62 serves a like purpose at the other end of the armature 26.

During the operation of the motor compressor, the gear 11 revolving in the gear case 2, acts as a pump and carries'considerable oil 5 to the inion 12. This oil 5 is deflected endwise rom the gear 11 upon commg in contact with the inion 12, part of the oil passing through t e opening 35 and into the rear pocket 32. The rest of the oil' 5 which does not pass through the opening 35 flows back to the oil basin in the lower portion of the gear case 2. During its passage backto the oil basin,'a portion of the 011 5 flows into the basin at the top of the bearing cap 15, passing from thence through the holes 17 to the bearing 8. The oil 5 in the ocket 32 is carried up to the bearing 30 by t e oil ring 34. As the oil 5 rises in the pocket 32, a portion of it will flow out of said pocket 32through the pi e '36, and from this plpe into the front poc (et 31. Here the o l is carried up to the bearing 29 by the .011 ring 33. As the oil 5 rises in the pocket 31, e pocket 31 through the over flow 37, and will -be recipitated into the basin at the top of the ront cap 14. From this basin the oil will passdown through the openings 17 to the caring 7, and from thence back to the oil basin at the bottom of the crank case 1. It might be desirous to have an overflow similar to that in the front bearing pocket 31, in the rear pocket 32, the discharge therefrom the machine is accomplished and the ma-' chine needs no manual oiling when once assembled.

7 It should be understood that it is not desired to be limited to the exact details of construction shown and described, for .obvious modifications will occur to a person skilled in the art. v
