ATTACHMENT FOB SIGHT-FEED VALVES.

, Application filed June '7', 1915. Serial No. 32,795

of Iowa, have invented a certain new and useful Attachment for Sight-Feed Valves,

of which the following is a specification.

The object of my invention is to provide an attachment for sight teed valves adapted to be substituted in place of the glass cylinder employed in an ordinary type of sight feed oiling device, which can readily and easily be installed or removed, and with which the exahust or other heated gases or hot water may be readily and easily connected for heating the oil to be supplied to the machine.

A further object is to provide in this connection a device having parts adapted to show the level of the 011 in the device.

My invention consists in the construction arrangement and combination of the various parts 01 the device whereby the objects contemplated are attained as hereinafter more fully set forth. pointed out in my claim and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a portion of an engine equipped with an ordinary sight oil feed having an attachment installed thereon embodying my invention. Fig. 2 shows a vertical sectional view through the oil feed with my attachment thereon.

In the accompanyingdrawings, I have employed the reference numeral 10 to indicate generally the upright tube forming a part of the ordinary sight feed oiler. The lower end of the tube 10 communicates with an oil discharge tube 11. On the lower end of the tube 10, near the lower end thereof is an upwardly opening cap 12, adapted to receive the ordinary glass cylinder. Below the cap 12 is a sight glass 13 of the ordinary type. On the upper portion of the tube 10 is a downwardly opening cap having an internally screw threaded annular flange 15. The parts described being of the ordinary construction.

In the ordinary type mentioned, a

sight feed oiler of the glass cylinder is placed between the caps 14 and 12. There my device is used I mount between the caps 14 member 16, having an Specification of Letters Patent.

inwardly spaced cylindrical wall 17 suitably connected at its upper and lower edges ith the cylinder 16 by members 18, whereby there is formed an inner oil chamber 19 and an annular chamber 20 surrounding the cylindrical member 17. In the wall of the lower part of the tube 10 within the chamber 19 is a hole 10 whereby communication between the tube 10 and chamber 19 is established.

The cap 1% is provided with an opening 21, above which is an ordinary movable cover plate 22, pivoted on the tube 10. The upper end of the tube 10 is screw-threaded and receives a nut 23, by which the caps are firmly held on the cylinder 16. The member 16 is provided with two laterally extending passages 2% and 25 one of which is adapted to be connected with a tube 26 for supplying heated gases, for instance from the exhaust of the engine, and the other of which is adapted to be connected with a discharge tube 27. Extending through the wall 16 and through the chamber 20 is a tube 28 which communicates at its inner end with a chamber 19 as illustrated by the dotted lines 29 in Fig. 2.

Mounted on the outer end of the tube 28 is an ordinary oil sight glass 30 having a small air opening 30 in its top cap shown by dotted lines in Fig. 1. It will be seen that my improved attachment may be mounted on the tube 10 and between the caps 12 and 14, and in place of the ordinary glass cylinders, and may be so connected with a suitable source of heated gas or the like as to permit proper heating of the oil within the chamber 19.

The tube 28 communicating with the chamber 19 and also with the sight glass 30, enables the oil to stand in the glass 30 at the same height as in the chamber 19, so that the user of my device can at all times easily determine the position of the oil in the chamber 19.

In the practical use of my device, my attachment is mounted on the tube 10 in the place of the ordinary glass cylinder, and the tubes 27 and 26 are properly connected. The supply of gas may be shut off, by means of a valve 31 in the tube 26 whenever desired.

My improved attachment may be made in a variety of forms and it is my intention to 7 ing through the walls of said chambers and 10 which may be included within the scope of communicating with the oil chamber, and

an oil sight glass mounted on said tube.
