JAMES PHILLIPS. F HAZLETON, PENNSYLVANIA.

COMBINATION CLEANER AND ELALlEIPER.

Application filed July 28,

To all whom it may concern:

Be it known that I, JAMES PHILLIPS, a citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Combination Cleaners and Tampers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combination cleaner and tamper for use in mines particularly when mining anthracite coal.

In the mining of anthracite coal, the coal is first drilled then cleaned and thereafter filled with dynamite in stick form.

After the hole is drilled, the miner uses 0 a cleaning tool to remove the loose coal from the hole and thereafter tamps one or more sticks of the dynamite into the hole. For the purpose of tamping the dynamite into the hole, some miners use a round stick of wood which is considered safe and is in accordance with the mining laws. Many miners however use their cleaning tool, which is of metal, for the purpose of tamping the dynamite sticks into the hole, which is directly opposed to the mining law and the cause of many accidents and explosions within mines. In addition, when the wooden stick is used, it must be carried additionally or as a separate tool to the cleaning tool and furthermore it is difficult to obtain readily.

In accordance with the present invention it is aimed to combine the cleaning tool and stick into a single tool to the end that the inconvenience of procuring and carrying two tools is overcome and to the further end that the miners must follow a safe method in the tamping of the dynamite or explosive into the hole.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment. A

In said drawings Figure 1 is a view in side elevation illustrating the improved tool;

Figure 2 is a View of the tool taken at a right angle to Figure 1;

Figure 3 is a longitudinal substantially central sectional view through the tool taken on the line 3-3 of Figure 2, and

1923. Serial No. 654,474.

Figure 4 is a perspective view of a second form of tamping stick or plug.

Like reference characters designate like or similar parts in the different views.

In reducing the invention to practice, a cleaner is provided as at which is substantially wedge shape as at 11 adjacent one end and which merges into an elongated blade 12 having a scoop or flange 13 at its distal end. This cleaner 12 is preferably relatively wide and made from metal. EX- tending upwardly and integrally with the cleaner is an attaching shank 14, exteriorly screw threaded as shown.

A metallic socket 15 is provided, being inwardly thickened at one end as at 16 and having a bore provided with screw threads 17 adapted to engage the screw threads of the shank 14 whereby the cleaner may be detachably connected through the socket. The socket is hollow at 18.

A. clamping rod or plug 19, preferably round in cross section and of wood, at a reduced end 20 is disposed within the hollow 18 of the socket 15 and fastened against accidental detachment as by suitable fastenings 21 passing through the socket and into the portion 20. The fastenings 21 may be screws, nails, or the like. 8

As a result of the present invention, the cleaner 10 may be operated with the tamping rod 19 serving as a handle in order that the flange 13 will engage and remove loose material from a hole in a coal mine after the same has been drilled. After the hole is cleaned, the dynamite sticks are placed therein and the tool, with the cleaner uppermost serving as a handle is used so that the rod 19 will tamp the stick into the hole. As a result of this construction, a wooden or other rod 19 which may be safely used to tamp the dynamite, as distinguished from the metal rod, forms part of the cleaner and it must be used for tamping purposes since a metallic rod does not form part of the cleaner. This conduces greatly to safety since it overcomes the carelessness of many miners using a metallic rod as usually con nected with a cleaner instead of a wooden or other rod with which a dynamite or eX- plosive charge may be tamped safetly.

It will be understood of course that the sizes and dimensions of the parts will vary according to the sizes of the holes and the depth to which they are drilled.

Figure 4 illustrates a second form of ooden rods. This rod is designated 22 and is used instead of the 1:06. 19 when the drilled hole is of greater diameter than that which connects rod 19 thereto. Such rod 22 however may be used in the same sized socket 15 since it has a reduced attaching portion similaiin size to the portion 20. From the portion 2?). 1-0:} tapers as at into a larger poition 25. ltortion is the temping portion and preferably round like the rod 19.
