Specification of Letters Patent.

Application filed February 6, 1914. Seria1 No. 817,070.

he present invention appertains to a valve oil or lubricant atomizer for use in connection with automatic lubricating appliances, applicable to steam lines orsupply pipes for steam engines, and aims prlmarlly to provide in combination with an ordmary or prevailing type of lubricator, a-novel and improved device for atomizing the lubricant fed with the steam into the cylinder or cylinders, whereby the valves, piston andother wearing parts may be effectively lubrlcated with a minimum expenditure of lubricant.

It is also the object of the present invention to provide an atomizer device of the nature indicated, embodying a unique assemblage of parts to bestcarry out the results desired, whereby the device will be practical andefficient in its use, and will be of simple and inexpensive construction.

With the foregoing general objects outlined, and with other objects in view, whlch will be apparent as the nature of the lnvention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated inits preferred embodiment in the accompanying drawing, wherein Figure 1 is a side elevation of a common lubricating apparatus applied to a steam line or supply pipe, and embodying the present invention. Fig. 2 is a longitudinal section of the atomizer, parts being shown in full. Figs. 3, 4 and 5, are cross sectional views taken on the lines 3-3, H, and 55 of Fig. 2, respectively.

The lubricating apparatus, which is of a 1 common or prevailing type, embodies the lubricator 2, containing the lubricant, such asvalve oil or the like, and connected by means of a pipe 3, to the steam line or supply pipe 1, at the point 4. As illustrated, the steam line, or supply pipe 1 leads downwardly to the steam chest (not shown) so that it will be understood that the steam flows downwardly in the apparatus, as illustrated. l

Ordinarily, the lubricator outlet is connected directly to the steam line or pipe 1, so that the lubricant is discharged directly into the steam line.. This, however, has been found of disadvantage, inasmuch as the oil or lubricant will be carried into the steam chest, and thence through the valve or valves and into the cylinders, the oil .or lubricant not being properly atomized, which would result in an excessive expenditure of lubricant, and in an inefiicient lubrication of the valves and piston.

In carrying out the present invention, an oil and steam chamber or compartment 5 is disposed between the lubricator 2 and. the steam pipe 1, the said chamber being preferably in-the form of a vertical cylindrical casing, and having its upper and lower end portions, connected to the lubricator 2 and the steam pipe 1, respectively, by means of the pipe sections 6 and 7, in order-that the lubricant passing from the lubricator 2 to the steam pipe, will be constrained to pass in drops,

the chamber 5 is' also connected by means of a pipe section 9, to the steam pipe 1, at

the point 10 intermediate the point 4 at PatentedFeb.16,15915.

which the pipe section 3 is attached, and the I point 8 at which the pipe section 7 leading from the chamber 5 is attached.

From the foregoing general outline of the apparatus, it will be apparent that as the steam is admitted into the cylinder, the pressure at the point 8 will be lowered, and as a result of the higher pressure at the point 10, steam will be admitted through the pipe section 9 to the chamber 5 and the usual supply of lubricant will pass into the chamber 5 from the lubricator whereby the lubricant and steam are brought together in a peculiar manner, within the chamber 5, so as to atomize the lubricant which passes from the chamber'5 into the steam pipe and finally into the steam chest and cylinder.

The construction of the atomizer per se is as follows: The atomizer chamber or casing 5 is provided with a lateral nipple or coupling member 11 adjoining its upper end, through which the pipe section 6 leading from the lubricator 2 is attached, and is further provided with a lateral nipple or coupling member 12 adjoiningitslower end,

to which the pipe section 7 leading to the steam pipe, is attached. The upper end of the casing or chamber 5 is open, and has a closure or cap 13 threaded or otherwise engaged therein, a nozzle tube 1% depending from the closure or plug 13 and coupling means 15 being provided on the plug, to which the pipe section 9 is attached. The nozzle tube 14: preferably has its lower end closed, and-terminating adjoining the lower end or bottom of the casing 5, the nozzle tube also being disposed axially within the casing. l

Mounted upon the nozzle tube 14 is a series of lubricant bafiies, which are intended to catch or arrest the lubricant admitted from the lubricator 2, through the pipe section 6 engaged through the inlet nipple or port 11, whereby the steam discharged from the nozzle tube 14, will atomize the lubricant, as will hereinafter more fully appear. To this end, a series of concaved or dished

baffle disks

16, 16 and 16 are mounted upon the nozzle tube 14 at spaced points the up permost baffle disk v16 being disposed immediately below the inner end of the pipe section 6, while the lowermost baffle disk 16 is disposed adjoining the outlet 12. Immediately above the intermediate and

lowermost bafiie disk

16 and 16" respectively, are disposed conveXed or cambered baffle disk 17' and 17 which are slightly smaller in diameter than and arranged in pairs with the

respective disks

16 and 16".

The lubricant arrested or caught by the several baflie disks, is caused to travel along the disks in a peculiar manner to subject the same to the action of steam discharged from the nozzle 14, as will hereinafter appear, and to this end, each of the

disks

16, 16' and 16 is provided with an annular series of openings or notches 18 surrounding the nozzle tube 14:, and with the upstanding flanges or lips 19 at and coextensive with the outer edges of the openings 18. The

baiiie disks

17 and 17 are each provided with a series of upstanding peripheral flanges or lips 20, which have the passage 21 between their ends.

Each pair of disks 16-17 and 16--17, are connected by an annular series of upright or vertical stays or bars 22, which have their lower ends attached to the respective concaved disks, and which have their upper ends attached to the periphery of the respective convexed disks, adjoining or directly below the passages 21.

The nozzle tube let is provided with a plurality of radial outlet apertures 23 between the

disks

16 and 17, and the

disks

16 and 17 The apertures 23 permit the steam to be discharged from the nozzle tube 14 to pass outwardly from between the respective baffle disks.

The operation of the apparatus, including the atomizer as above described in detail, is as follows. As intimated hereinbefore, when the pressure of the steam is lowered at the point 8, due to the admission of the steam into the cylinder, the steam at the point 10 will be at a higher pressure, than at the point 8, and a supply of steam will be admitted into the nozzle tube 14 from the pipe section 9. It will be evident that the lubricant passing through the inlet 11 from the lubricator, and the steam entering the cas ing 5 through the nozzle 1d, will be brought together to carry out the functions desired, by the atomization of the lubricant in order that the lubricant may be carried off in the form of a vapor with the steam in leaving the atomizer to enter the steam chest with the greater portion of the steam passing directly along the steam line or pipe 1.

The drops of lubricant carried into the casing or chamber 5 from the lubricator 2, will be arrested or caught by the

baffle disks

16, 16 and 16", particularly the first mentioned one, which is arranged directly below the pipe section 6. The lubricant or oil will flow toward the center of the disk 16, or toward the nozzle tube 14, due to the concavity of the disk 16, and as a result the lubricant will fiow around the flanges or lips 19 and through the openings 18, down the nozzle tube 14 to the convened or cambered baffle disk 17. The conveXed disk 17' will shed the lubricant to the flanges or lips 20 and through the passages 21, from whence the lubricant will fiow or run down the stays or spacing bars 22 to the peripheral portions of the succeeding baffle disk 16. From the disk 16, the lubricant will flow through the respective openings 18, down the nozzle tube, to the next succeeding baffle disk 17, the lubricant passing around the disks, 17 and 16 inprecisely the same manner as with the

disks

17 and 16.

It will be noted that the supply of steam admitted into the nozzle tube 14 will be discharged through the apertures 23 between the respective disks 1617 and 16-17, in order to so attach the lubricant flowing around the disks, as to atomize or vaporize the same, the current of steam limiting or ainalgamating with the lubricant vapor, so that the mixture will pass through the pipe section 7 into the steam line or pipe 1 to commingle with the column of steam passing therethrough to the cylinder.

With the improved atomizer applied to the lubricating apparatus, the lubricant will not only be atomized and vaporized, but will be heated, to the same temperature as the steam, so that the lubricant will be con- 125 veyed in an atomized form into the steam chest, through the valve or valves and into the cylinder, whereby the valve or valves piston cylinder walls, and other wearing parts will be lubricated, to reduce friction to 330 a minimum, and with a minimum expenditure of lubricant or valve oil.

It will thus be obvious that the improved apparatus, as herein described," will be thoroughly eflicient for the purposes indicated; whereby those disadvantages incident to the use of an ordinary lubricator, will be eliminated.

Having thus described the invention what is claimed as new is 1. A vaporizer of the character described, comprising a casing having a lubricant inlet at one end and having an outlet at its other end, a series of lubricant baflies between the inlet and outlet, and steam admitting means extending longitudinally of the chamber and having discharge means coacting with the baffles.

2. In a lubricating apparatus, a vaporizing chamber attachable to a steam line and having inner barlies, means for supplying lubricant to the chamber, and steam admitting means extending axially within the chamber, and having discharge means in cooperative relation with the baffles.

3.
