1 Claim.

The present invention relates to the construction of a gun designed to detectsludge or other foreign matter which has accumulated in the oil of automobile crankcases and is designed for use particularly by filling stations, garages or other like automobile serving places.

A further important object of the invention resides in the provision of a gun of this nature which is simple in construction, easy to operate, handy, efficient and reliable in use, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:- V

Figure 1 is a side elevation of a gun embodying the features of my invention.

Figure 2 is a top plan view thereof.

Figure 3 is a detail section taken substantially on the line 3-3 of Figure 2 taken vertically.

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 3.

Figure 5 is a fragmentarily vertical sectional view throughthe upper portion of the jar.

Figure 6 is a plan View of the strainer disk showing the arcuate slot therein.

Referring to the drawings in detail it will be seen that the numeral 5 denotes a block of a substantially triangular formation provided with right angularly disposed necks 6 and I.

An elongated cylindrical casing 8 has one end threaded in the neck 6 and a cap 9 is threaded on the other end thereof through which is slidable a shank ID one end of which is attached or fixed to a plunger H and the other end or outer end is formed into the configuration of a handle l2.

A jar M has its open end threadedly engaged in the neck 1. V

The head or block 5 is providedwith a passage l5 leading from the center of the neck 6 to the approximate center of the neck I. Numeral l'l denotes a flexible hose or conduit engaged or fixed with a coupling l8 threaded in the head 5 and the head 5 is provided with a passage 19 leading to the jar M.

A hollow stem 20 is connected with the hose or flexible conduit l9 so that it may be readily engaged in the oil of a crankcase or the like.

A strainer disk 2i is interposed between the block 5 and the cylinder 8 as shown to advantage in Figure 3. V

The stem is inserted in the oil and the plunger is withdrawn, that is, moved toward the cap 9 and 5 a certain amount of the oil is withdrawn from the crankcase of the automobile and a certain amount is deposited in the jar M.

In actual operation the customer drives into a service station or garage and the attendant asks the customer if he wishes the oil tested. With proper permission being given, the attendant inserts the tube into the crankcase and in this way is able to come to a conclusion as to whether sufficient oil is contained therein. By utilizing 15 the plunger the attendant withdraws a very small portion of the oil and deposits the same in the jar thereby being able to tell the customer whether the oil is in good condition or not.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

What is claimed is:-

A device of the class described comprising a block having threaded necks disposed in right angular plane with a passage connecting the central portions of the necks, a cylinder threaded in one of the necks, a plunger movable in the cylinder, means for operating the plunger, a jar having an opening, the open end of the jar being threaded in the other neck, the end of the passage in the 'block adjacent the jar lying in a plane disposed above the open end of the jar, a tube, means operatively engaging the tube with the block and a passage extending from the said means to the jar.
