DISTRIBUTOR-TESTING DEVICE.

Application filed May 2,

This invention relates to testing devices for determining if an automobile distributor is functioning properly to produce a spark in each cylinder of an automobile.

In shooting trouble about an automobile, it is often necessary to investigate and test the distributor to determine whether it is functioning properly. However, heretofore, the methods used for such a purpose have poven inconvenient and laborious and unsatlsfactory to unskilled persons.

It is an object of this invention to provide a device by which it may be readily determined whether a distributor is functioning properly to produce a spark in each cylinder.

It is a further object to provide a testing device of the character indicated which may I be conveniently mounted on the dashboard of an automobile and which may be readil manipulated by unskilled persons.

These and other objects are attained by the novel construction, combination and arrangement of parts, hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure, and in which Figure 1 is a front view of the device.

Figure 2 is a cross-sectional side view.

Figure 3 is a rear View of the device.

Figure 4 is a cross-sectional view taken along line 4-4 of Figure 2;

Figure 5 is a cross-sectional view showing the manner inwhich leads from a distributor are connected to the device.

Referring to the drawings, the device is shown to comprise a block 6 of insulating material to which are connected the conducting bars 7 by means of contact screws 8, there being a conducting bar 7 for each cylinder of the automobile. To each bar 7 is connected, by means of a screw 9, a lead wire 10, which is also connected to the distributor cap at the same place, corresponding wires are connected which lead to the various cylinders of an automobile.

A shaft 11 is rotatably mounted in the block 6 and is provided with a knob 12 at one end, the other end of the shaft having connected thereto a spring contact finger 13, the latter being held to the shaft by means of the nut 14. At the outer end of the contact finger 13 is a contact button 15 which is adapted to engage the contact screws 8. Resting upon the shaft 11, in a recess in the 1928. Serial N0. 274,419.

block 6, is a metal block 16 engaged by a spring 17, the upper end of the spring pressing against a metal cup 18 which supports a vacuum tube 19, the latter being visible through an aperture 23 in the face of block 6.

The upper end of the vacuum tube 19 rests in a second metal cup 20, the latter being engaged by a recessed metal nut 21, threaded in the upper portion of block 6. The metal nut 21 is grounded by means of a wire 22 connected thereto.

In operation, the finger 13 is moved so that contact will be made with each of the contact screws 8, and if the distributor is functioning properly a spark will be produced in the vacuum tube and will be visible through the aperture 23. If no spark is produced when the finger is in contact with a specified contact screw, then the operator knows at once the exact location of the trouble and need not spend time searching elsewhere.

From the above description, it will be seen that I have produced a simple testing device which may be conveniently located and easily manipulated to determine the functioning of a distributor.

The foregoing disclosure is to be regarded as descriptive and illustrative only and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed, including many modifications,

without departing from the general scope herein indicated and denoted in the appended claim. 1

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

A testing device for distributors comprising a block of insulating material having a. recess therein, a vacuum tube positioned in the recess, metal cups at each end of the vacuum tube, a shaft rotatably mounted in the block, a spring contact finger connected to the shaft, a plurality of contact screws mounted on the block, each screw being connected to a distributor, a metal plug engaging one of the metal cups, said plug being grounded, means for connecting the other metal cup with the shaft, and means for rotating the shaft to move the finger in contact with the contact screws.

In witness whereof I have affixed my signature.

CARL KUPPERS.
