merits-in Boat-Pusher Heads, of which the following is a specification.

My invention relates to means for poling or pushing boats over flats or shallows such as are used by gunners andunderlike circumstances, and'particularly itrelates to a head to be attached to the pushing pole, the object of the invention being to provide a pushing pole head'having such a shape and contour as-shall especiallyfit it for the work to be done, which shall provide an extended surface for bearing against the mud of the riverbottom, of such contour that it will have a more or less extended contact with the ground or mud, in all positions of the pole and which will permit the pushing head to be readily detached from engagement with the mud in case itis forced into the mud too far.-

The invention consistsbroadly in a pusher having at its end. a globular head which is so attached toithe pole that it is readily removable therefrom, or replaceable upon another pole.

In the drawings Figure 1, is a side ele-* vation of a pusher head and part of a pole constructed n accordance with my' invention. Fig. 2, is a longitudinal section there-- of showing the preferred attachment ofthe head to the pole. I v

In the drawings- A designates a' boat pushing pole ofany 'd'esired form or length, B designates a cylindrical ferrule capable-of receiving the lower end of the ole, the extremity of -saidferrule being ormed" with a hemisphericalsocket' C." Fastened within the socket O is a solidball D of sufficient weight to keep the end of the pole downward and prevent any tendency .on the part of the-pgle. to float upward. While the head C shou be'heavy enough, at :the same time it should not be so heavy as-to add to the.

work of olin'g.

Preferably the ferrule is formed of sheet metal bent into a cylinder, with the hemispherical socket C thereon. The socket G is brazed or soldered on the upper end of the ferrule. formed of any suitable material, butjpreferably of .wood,'andfits within the hemiand not be softened by the water.

rule in any suitable manner.

Thespherical head D may be spherical socket, and is fastened therein by means of cement, white lead, plaster, or any other suitable material of [such character that it will hold the head solidly in place,

While I have described the socket C as formed separately from the ferrule B, I do not wish to be limited thereto as the socket might be attached to or formed with the fer- Openings are made in the ferrule into which screws 1) may be inserted whereby the head may be attached to the pushing pole.

It will be seen that no matter at what angle the pushing pole is held the globular .head will always have a good bearing surface; and that at the same time it is so en-' largedthat the pole can be pushed into the mud or ground, and hence there will be no pull required in order to release the pole. With ordinary poles shod with a device which penetrates the ground there is almost always a jerk required in order to free the pole from the mud. This jerk is very liable to occur at an inoppo'rtune moment as when the gunner in the bow of the boat is about to fire. This of course, destroys his aim and causes him to miss. I

With my device there is no jerk, the pole may be easily detached from engagement with the'surface of the mud, it'may easily slip along the surface of the mud, and has a good contact with the surface no matter at what angle the pole is held, or what the contour, of the bottom of the stream. If the pole is broken the device can be readily attached to another pol'eyorit may be removed from the pole, when the necessity for its use'has expired.

Another point of advantage is that the globular contour of the head permits it to be easily withdrawn in case by any chance 'itshould be submerged in the mud. The

globular contour prevents it sticking and also presents in all positions of the pole a pole, a socket and ahead secured within said socket.

3. A head for pushing poles of boats comprising a cylindrical ferrule and hemispherical socket formed at the end thereof and a solid spherical head held within said socket.

A pushing pole for boats comprising a cylindrical ferrule adapted to receive a pole having at the end thereof a hemispherical socket, a solid ball within said socket and cement material between the ball and the socket.

5. A head for the pushing poles of boats comprising a ferrule having a hemispherical socket at one end, said socket having a head 5 formed onit's edge, and a wooden ball inserted within said hemispherical socket and cemented thereto.
