Filed Aug. 6, 1934 INVENTOR ATTORNEY WITNESS Mw Patented July 9, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a spark plug cleaner and more especially to a sand blast cleaning appliance for spark plugs.

The primary object of the invention is the provision of an appliance of this character, wherein the same in its construction is usable at automobile service stations for the purpose of cleaning spark plugs, in that a blast of air, the volume of which is controllable, acts upon loose sand contained within a receptacle and such sand, under the air blast, is directed to the spark plugs as tted in this receptacle, so that all foreign matter, carbon and other adhering particles can be readily and easily removed under the action Another object of the invention is the provision of an appliance of this character, wherein the receptacle for containing the loose sand is of novel form so as to permit the fitting of a rspark plug therewith, so that the same when attacked by a blast of air will operate to thoroughly clean the spark plugs for the proper conditioning thereof for use in anvinternal combustion engine. v

A further object of the invention is the provision of an appliance of this character, wherein a spark plug can be cleaned thoroughly and with dispatch without the necessity of the manual handling of the plug and without possibility of damage thereto during the cleaning period.

A still further object of the invention is the provision of an appliance of this character which is simple in construction, thoroughly reliable and effective in its operation, convenient for easy handling, automatic in action, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation partly in section of an appliance constructed in accordance with the inventionl Figure 2 is a sectional view on the line 2 2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a top plan View.

Figure 4 is a fragmentary sectional View on the line 4-4 of Figure 1 looking in the direction of the arrows.

Figure 5 is a plan View of the air blast nozzle.

Figure 6 is an enlarged fragmentary vertical sectiona1 View thereof.

Figure 7 is a fragmentary vertical sectional View through the control valve for the air feed plpe.

Similar reference characters indicate correspending parts throughout the several views in the drawing.

Referring to the drawing in detail, the appliance comprises a horizontally disposed cylindrical receptacle I0 supported upon a stand II, it being made fast to a oor or foundation in any suitable manner, the receptacle IU at one end having a removable head I2, so that access may be had to the interior thereof, and this head is detachably threaded on the receptacle.

Rising from the top of the receptacle I0 is a hood I3 which is open, at I4, at opposite sides thereof and constitutes a roof for a spark plug I5 which is detachably threaded in a receiving hole I6 provided in the top of the receptacle I0 so that the base of the plugY I5 with the sparking point I'I will project into said receptacle for the purpose of the cleaning of the plug in a manner presently described.

Arranged at the bottom of the receptacle Il] and vertically aligned with the hole I6 for accommodating the plug I5 is a perforated air blast nozzle I8, it being connected with an air feed pipe I9 which, through the union 20, has connection with an air supply pipe 2| leading from any suitable source of air supply under pressure. Fitted in the pipe I9 on that side of the union 20 having the run to the nozzle I8 is a valve casing 22 having therein a cut-off valve 23 provided with a push plunger 24 which terminates exteriorly of the casing 22 in a head 25 and this valve 23 is normally held seated or in closing position through the medium of a spring 26 as confined within the casing 22, so as to shut off the air supply under pressure through the pipe I9 to the nozzle I8. The casing has tted therewith a spring tensioned latch 21 which is engageable selectively in keeper grooves 28 in the stem 24 of the valve 23, so that the said valve 23 can be latched in several opened positions for varying the flow of air under pressure through the pipe I9 to the nozzle I8 for increasing or decreasing the blast within the receptacle I0. This receptacle I0 is adapted to contain a quantity of loose sand 29 and the same in quantity covers the nozzle I8. Upon the flow of air under pressure through the pipe I9 to the nozzle I8 the latter effects a blast of the sand 29, whereby it will act upon the spark plug I5 mounted in the hole I6 for the thorough cleaning of such plug. Arranged above and in vertical alignment with the hole I6 and the nozzle I8 are superposed or spaced substantially conical-shaped bales 30 and 3|, respectively, these directing the sand blast toward the plug I5 to assure a direct blast action thereon. The baille 30 is hung from the top of the receptacle II), while the baille 3| is supported upon brackets 32 suitably arranged within the receptacle I0.

The top of the receptacle I outside of the hood I3, preferably beyond opposite ends thereof, has air escape ports 33 having wire mesh coverings 34 so that the sand 29 when under blast cannot escape from the receptacle I0, but the air liberated within the receptacle I0 can have escapement therefrom.

Underlying the ports 33 are shields 35, these relieving blasts of sand against the coverings 34 to avoid choking at the ports 33.

The latch 2'I is manually controlled and is operable to lock the Valve 23 in selected open position.

The union 20 has joined therewith a valved air outlet nipple 36, the valve 3I being manually controlled and adapted for iitting with this nipple 36 is a spark plug so that a direct air blast thereagainst can be had through the nipple 36 for the cleaning of such plug.

It should be seen that the plug I5 when fitting the hole I6, when the appliance is in operation, with the nipple 36 closed, will be subjected to a sand blast for the cleaning of such plug.

The plug I5 is readily insertable in the hole I6 in the receptacle I0 by introduction through either open side of the hood I3 and is threaded into the hole I6, as will be apparent from Figure 1 of the drawing.

The receptacle ID can be properly filled or supplied With sand 29 on removing the head I2 from said receptacle, the removability of the head being for this purpose.

Spark plugs can be thoroughly cleaned to remove carbon and other deposits at the sparking points of such plugs with dispatch and automatically in the use of the appliance embodying the present invention.

What is claimed is:

An appliance of the character described comprising a horizontally arranged cylindrical receptacle adapted to contain loose sand and having a spark plug opening centrally located at the uppermost portion thereof, a removable head at one end ofvthe receptacle, a hood rising from the uppermast'portion of the receptacle to form a roof for a spark plug when engaged in the spark plug hole and having openings at opposite sides thereof for the free introduction of the spark plugs to the said spark plug hole, a perforated blast nozzle located in vertical alignment with the spark plug hole and within the receptacle close to the lowermost portion thereof, means for supplying air under pressure to the said nozzle for directing the loose sand in a stream toward the spark plug hole, concentrically arranged substantially conical-shaped bailles within the receptacle and disposed in vertically spaced relation to each other in alignment with the nozzle and said spark plug hole, the uppermost baille being joined with the uppermost portion of the receptacle to depend therefrom elevated with respect to the other bale, brackets arranged in the receptacle and supporting the lowermost baille in a lowermost position with relation to the other baille, the said receptacle at its uppermost portion being provided with air escape ports close to opposite ends thereof, shields depending from the uppermost portion of the receptacle and downwardly diverging beneath the air escape ports, and wire mesh coverings for the said air escape ports.
