SPECIFICATION forming part 0f' Letters Patent No. 648,212, dated April 24, 1900.

Application filed October 6 1899.

T0 all whom, t may concern:

Be it known that I, HENRY T. MASON, a citi# zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oiling Mechanism, of which the following is a specication, reference be# ing hadtherein to the accompanying drawing.

The invention has relation to an improvedv type of oiling mechanism particularly designed for use in oiling verticalshafting; and the invention consists in the novel construction of the mechanism referred to, as Will be more fully hereinafter shown and described.

The drawing is a vertical central section through a shaft, illustrating my improved oiling mechanism therefor.

The reference-letter A designates a vertical shaft, in which is formed a central bore B and counterbores O and D, and Within the shaft at the junctions of the bores are arranged a series of plugs 'E of a size corresponding to their respective bores, as shown. These plugs divide the interior of the shaft into a series of reservoirs adapted to be filled with oil and provided with means for distributing the oil to the shaft at different parts of its length for the Apurpose of oiling pulleys, gear-wheels, dac., that may be arranged upon the shaft for rotary movement.

The letters F and G designate two bandwheels sleeved upon the shaft and held in their respective positions by means of collars H. These wheels are lubricated by the following means: Each reservoir is provided with an oil-inlet passage I and an oil-discharge passage J, these passages being preferably arranged, respectively, one above the other and leading -from the reservoir to 'the periphery of the shaft.

K designates bores of considerably-smaller diameter than the oil-passages, which are formed in the shaft extending from substan-y tially the middle of each lower oil-passage in a diagonal direction to the shaft-periphery,

in the periphery of the shaft, with which the small bore communicates.

M designates oil-cups secured within the upper passages of the reservoirs, and O represents threaded plugs within the lower discharge-passages adapted to control the flow .a single bore were formed.

serai No; 732,778. (No modem agonal bore.

From the description of the mechanism thus set forth it will be observed that by forming counterbores in the center 0f the shaft in the manner set forth I am enabled to partition off the interior of the shaft by means of the plugs in a more ready manner than if This follows from the fact that the plugs constituting the partitions only have a driving fit with the bores that they are intended to engage with, thus dispensing with the necessity of forcing the plugs the entire length of the shaft; also, by forming these oil-reservoirs Within the shaft I am enabled to keep a large supply of oil on hand, which by means of the plugs O may be distributed to a nicety to the rotating gears or hand-wheels upon the shaft.

The mechanism as thus far described is shown to be applied to a stationary shaft. It will be obvious, however, that the same mechanism may be applied to a vertical shaft that is mounted for rotary movement, as in case of mill-spindles. I have therefore shown the shaf t as constructed for rotary movement with my improved oiling mechanism applied thereto.

P designates a base or step in which a socket Q is arranged, and within the socket the' end of the shaft extends. The diagonal bore K in this case leads from the lower passage of the reservoir to a point within the socket, whereby the contacting surfaces of the socket and shaft are thoroughly lubricated. I have also provided small diagonal apertures R, leading from the lower reservoir in the shaft to the base of the latter, whereby the shaft end may be lubricated. Also I preferably interpose between the said shaft end and the socket a tempered plate S, constituting a bearing for the shaft.

What I claim as my invention is- 1. The combination of a shaft having a central bore formed therein'constituting an oilreservoir, a transverse oil-passage leading from the periphery to the central bore, and a diagonal bore extending from the transverse passage Vto the shaft-periphery;v a plug, ar-

ranged within andoccupying a portionvonly of the transverse passage, said plug having its inner end located at substantially the j uncof the oil from the reservoir through the di@ IOO g v 648,212V

tion of said passage and the diagonal bore and adapted to control the iow of the lubricant through said diagonal bore, and an oil- 'cup communicating with the interior of the shaft, substantially as described.

2. The combination of the shaft having a central bore formed therein constituting an oil-reservoir, an upper and a lower transverse passage leading from the periphery of the shaft to the interior of the latter, and a diagonal bore extending from substantially the central portion of the lower transverse passage to the shaftperiphery; an adjustable plug arranged within and occupying a portion only of the lower transverse passage, said plug having its inner end located at substantially the junction of said transverse passage and the diagonal bore, and adapted to control the flow of the lubricant through said diagonal bore, and an oil-cup communicating with the upper transverse passage.

3. The combination of a shaft having a cen tral bore and a multiple of counterbores formed therein, plugs within the shaft at the junction of the bores dividing the interior of the shaft into a seriesvof central oil-reservoirs, each provided with an upper and a lower oilpassage, leading from said reservoir to the shaft-periphery, and the shaft having formed therein amultiple of diagonalbores of smaller diameter, one for each reservoir and leading from the lower passage of the reservoir to the shaft-periphery at a' point below the reservoir, an oil-cup communicating with the upper oil-passage of each reservoir, and a screwplug Within each lower passage controlling the ioW of the oil through the diagonal bore.

In testimony whereof I aix my signature in presence of two witnesses.

HENRY T. MASON.
