LUBRICATING fiEVICE.
Specification of Letters Patent.
Patented May id, 191%.
Application filed January 31, 1918. Serial No. 214,572.
To all whom it mag concern:
Be it known that we, NELSON T. Guns and ROBERT M. LONG, citizens of the United States of America, residing in Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating of which the following is a specification.
This invention relates to lubricating devices, particularly designed for the compression cylinders of air compressors, but it is to be understood that the device can he used for any purpose wherein it is found'applicahis, and the invention has for its object to provide, in a manner as hereinafter set forth, a lubricator that will satisfactorily supply a lubricant to the compression cylinder of an air compressor, more particularly, a cylinder of the cross-compound type of air compressor.
It is well known that railroad companies have experienced great difficulty in maintaining the high eiliciency in the air brake equipment, which is due primarily to the fact that the pistons in the compression chambers were not being properly lubricated, due to the fact that the compression chambers were either being flooded with the lubricant or not receiving the necessary quantity of lubricant at the proper time. Under such conditions the air-discharge of the compressor would become clogged up with carbon preventing the free discharge of air to the main reservoir, thus causing the compressor to heat and become defective, the I lubricating device forming the subject matter of this invention is not only designed to overcome the objections cited, but further provides a lubricating device, which is simple in its construction, inexpensive to manufacture, readily applied at minimum expense, conveniently set-up with respect to the compressor Without the employment of extra skill to apply or operate it, is adapted hereinafter set forth, which is economical in its use, overcoming Waste of oil and prolonging the life oi the compressor, thereby provide a lubricating device, in a manner as hereinafter set forth, whereby the feed of the lubricant can be controlled so that when the desired amount is supplied and furthermore to provide the device with means whereby the feed of the lubricant to the compressor is had only when the compressor is in operation, thereby eliminating all possibility of the compressor being flooded with oil,
A further object of the invention is to provide a lubricating device in a manner as hereinafter set forth, whereby the lubricant is atomized and distributed uniformly over the walls of the cylinder of the compressor chamber, thereby insuring a satisfactory lubrication of all parts at all times.
With the foregoing and other objects in view this invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can he resorted to which come within the scope of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views:
Figure l is an elevation of a cross-compound air compressor showing the adaptation therewith of a lubricating device in accordance with this invention.
Fig. 2 is a sectional detail illustrating the lubricating feed pipe for the high pressure cylinder.
Fig. 3 is a cross sectional view of the high and low pressure cylinders of the air compressor illustrating the lubricant feed pipes opening into the inlet passages of Said cylinders.
' Fig. 4:, is a vertical sectional View of the lubricant storage receiver.
Fig. 5 is a vertical sectional view of the valvular element for controlling the feed of the lubricant.
Fig. 6 is a section on line V- Fig. 5.
Fig. 7 is an elevation of the feed pipe coupling.
