V. ANGHEL OIL GAUGE I Filgd July 25, 192

Patented July 27, 1926.

UNITED STATES VASILE ANGHEL, OF NEW YORK, N. Y.

OIL GAUGE.

Application filed July 25, 1925.

My invention in its preferred form is adapted for use with motors of that type in which the crank case has a closure plate on the side thereof which may be removed to permit the inspection, repair or replacement of the piston rod,'bearings and associated parts. Certain models of the motor used on the White truck are of this type and have the closure plate disposed at an angle of about 45 to the vertical on the under part of one side. In this construction no satisfactory way has heretofore been adopted for determining the oil level in the crank case.

The main object of my invention is to provide as a new article of manufacture, an oil gauge adapted to be applied to the type of motor above referred to. In carrying out my invention I provide a closure plate which may be substituted for that on the motor, and having a float and level indicating means.

In the accompanying drawings I have illustrated one embodiment of my invention. In these drawings:

Fig. 1 is a face view of the plate looking in a horizontal direction.

Fig. 2 is a vertical section on the line 22 of Fig. 1, and

Fig. 3 is a section on the line 3-3 of Fig. 1, and in a plane atright angles to the plane of the plate.

In the specific construction illustrated, I provide a closure plate 10 adapted to be substituted in place of the closure plate on the side of the crank case, and having a marginal clamping portion 11. which is provided with suitable apertures for the clamping bolts or screws. The main body portion of the plate may be slightly convex to conform to the general curvature of the crank case.

This plate is provided with a chamber projecting outwardly therefrom, and opening upon the inner side directly into the crank case. This chamber is shown as being provided with an outer vertical wall 12, a bottom wall 13, a top wall 14:, and side walls 15. The side walls preferably converge and the outer wall is brought as close as convenient to the upper marginal edge of the plate, leaving room for the parts hereinafter referred to. The outer wall 12 preferably extends substantially vertically so that the bottom wall 13 is materially wider than the top wall 14. Thus the chamber so formed has the, minimum capacity for the intended pur- Serial No. 45,972..

pose, and to give proper strength and rigidity to the parts.

Within the chamber there is mounted a float 16 which may be of any suitable character, and secured to the float is a vertically disposed indicator rod or wire 17. The wire is mounted in and guided by a tube 18 which is detachably secured in a socket in the top wall 14: of the chamber. The tube at a pluralityof points is provided with restrictions which act as guides for the indicator wire .17. F or instance, the lower end of thetube 18 may be contracted to leave a passage but slightly greater than the wire, and adjacent to the upper end there may be provided an inturned head 19 leaving a similar internal passage. Thus the float wire does not frictionally engage with the guide tube except at these restricted portions.

The device is so constructed that the position of the upper end of the wire 17 may be seen when between the points corresponding to the high level and low level positions of the float. For instance, the side of the tube 18 may be cut away at the upper end, and may be provided with a pair of marks or other indicating means. As shown, it has an upper hole 20 and a lower hole 21 so positioned that when the crank case is filled to the desired extent with oil, the upper end of the wire will be opposite the upper hole 7 20, and when the crank case is nearly empty, the upper end of the wire will be adjacent to the lower hole 21.

The chamber is provided with an oil filling inlet adjacent to the indicator, so that the latter may be observed during the filling of the crank case. As shown, the top wall 14: at one side of the tube 18, has an inlet tube 22 normally closed by a cap 23. To permit the insertion of the float and tube at the time of assembly, or to permit the removal of these parts for replacement or repair, the bottom wall 13 is provided with a screw plug closure 24 coaxial with the tube 18, and slightly larger than the float 16. To prevent the float from being unduly affected by the splashing of oil in the crank case, the chamber has a guard plate or inner wall 25 which may be secured to the top and bottom walls of the chamber, but spaced from the side walls to permit the maintenance of the same level of oil in the chamber as in the crank case.

Although my improved device may be manufactured and sold with the engine as a part of the equipment of the latter, it is particularly adapted for use as a separate article of manufacture which may be made in various proportions and sizes to properly fit engines already on the market and equipped with other forms of closure plates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An article of manufacture comprising a closure plate adapted to be secured to a motor crank case in a plane below the maximum diameter of the latter and in an inclined plane, said plate having a float chamber projecting outwardly with its opposite side walls converging, said chamber having a substantially horizontal bottom wall, a top wall and converging side walls, a float within said chamber, an indicator rod se cured to said float, a substantially vertical guide tube extending upwardly from said chamber, and encircling said rod and a guard plate within the chamber between the float and the open inner side of the chamber.

2. An article of manufacture comprising a closure plate for the inspection and repair opening on the side of a crank case, said plate having a float chamber extending outwardly therefrom, a float within said chamber, a plate at the inner side of said chamber and spaced from the side walls of the latter to permit free access of oil from the crank case to the chamber, an indicator secured to said float, the bottom wall of said chamber having an opening coaxial with said float and of larger size and a closure for said opening.

Signed at New York in the county of New York and State of New York this 23rd day of July A. D. 1925.
