Application led August 5, 1920. Serial No. 401,353.

, have invented certain new and useful Improvements in Cases or Holders for Spark Plugs, of which the following is a speciiication.

This invention has for its object to provide an improved case or holder for carrying spare spark plugs such as are commonly used for ignition purposes in connection with internal combustion engines.

According to this invention I provide a case or holder in which the spare plug or plugs are not only protected from dust and damage by Contact with other articles but are also held so that the points are continually washed by a cleaning fluid such as petrol.

In order that the invention may be clearly understood and more readily carried into effect it is hereinafter described, in suitable applications, with reference to the accompanying drawings, in which Figure l is a sectional side elevation of a case for accommodating four spark plugs;

Figure 2 is an end elevation showing the case closed;

Figure 3 is a sectional plan View of said case;

Figure 4 is a sectional elevation of a case for holding a single plug;

Figure 5 is a plan view of same with the cover or lid removed;

Figure 6 is a plan view of the lower portion of a circular form of plug case, and

Figure 7 is a sectional plan view of said lower portion of the aforesaid case.

As shown and in carrying the invention into effect as applied to a case or holder for containing a plurality of spare plugs the device comprises a base-portion or well a which is provided with a hinged or otherwise removable lid or cover portion b and with an intermediate plate c provided with screw threaded holes d into which the lower' or threaded portions of the plugs e are screwed. The plate c may be brazed, soldered or otherwise fitted into the lower portion or well a of the case or holder so as to form la fluid-tight chamber, or chambers f forl containing the cleaning fluid g which may conveniently be petrol, In Figures 6 and 7 the plate c is shown screwed or otherwise fixed into or on the upper portion of the well a. The base or well a may form oine common chamber or it may, as in Figures 1 and 7, be subdivided by means of suitably formed partitions h to provide a separate well for each plug. The lid of the case is of such a height as to conveniently accommodate any ordinary or standard size of sparking plug and it may be secured thereto in any preferred manner. For instance for small numbers of plugs it may be found to be desirable to screw the lid b on to the container a as in Figures 4 to 7, or otherwise it may be held on by means of spring clips or in the case of four or more plugs arran ed in a line as shown in Figures l to 3. t may be convenient to hinge one end as at 'i -and to secure the other one by means of a clip j or otherwise. The lid need not necessarily make a liquid tight joint but it must be a suliiciently good fit to render the upper portion of the case dust proof.

In use the plugs c are screwed into the lower portion or well a of the case so that the cleaning fluid g in transit will be shaken into the lower portion of the plugs, which, if foul, will be cleaned thereby and kept ready for immediate use. Suitable washers or other means (not shown) may be provided to assist in making a Hind-tight joint between the plugs e and the plate c into which they are screwed.

Should fewer plugs than the number for which the case is designed be carried the plug holes d of the compartments not used may be sealed up by means of loose stoppers or in the case of subdivided compartments the latter may be emptied of their fluid contents. The cases may accommodate any number of plugs and may be shaped accordingly, and they may be cast or otherwise made in metal or any other suitable material.

What I claim is 1. A spark plug holder, comprising a container centrally divided, one part forming a bottom portion 4and having a plurality of transverse partition walls terminating below the upper edge of the outer wall, a removable plate formed with a plurality of spark plug receiving openings having fluid tight connection with the bottom portion, said partition walls forming an abutment to limit the insertion of the platein the bottom portion, and the other part being removably secured to the plate, whereby the last mentioned part may be removed to permit spark plugs to be inserted in the openingsin said plate for subjection tothe action of a cleansing Huid in the other part of said container.

2. A spark plug holder7 comprising a container having a lbottom part formed With aI plurality of transverse partition Walls ter-- minating below the upper edge of the outer Wall thereof, a lremovable plate formed With a plurality of spark plug receiving openings, having screw threadedlconnection with the inner Wall of the bottom part, the partition Walls forming a stop to the insertion of the plate in the bottom part, so that a portion of the plate Willl project abo-Ve the edge 'of said part, said platealso forming a fluidl tight connection with said bottom part, and a cover for removable connection With the projecting portion of said plate.

In testimony whereof I have hereunto signed my name.
