HENRY I. PETREE, OF LITTLE FALLS, NEW YORK.

PILE OR POST DRIVER.

SIPECIFICATION forming part of Letters Patent No. 538,382, dated April 30, 1895.

Application filed January 26, 1895- Serial No. 536,341- (No model.)

To all whom it may concern:

Be it known that I, HENRY I. PETREE, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Post or Pile Drivers; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in post or pile drivers, and has special reference to a device in the form of a mallet or hammer for manually driving a post after the opening has been made by a device which I show and describe in the present application.

The invention consists of a maul or hammer embodying novel features of construction substantially as shown, described and claimed herein.

Figure 1 represents a perspective view of my improved post driver. Fig. 2 represents a sectional view thereof. Fig. 3 represents an enlarged detail view of the mallet head to show the manner of connecting and strengthening the same; and Fig. 4 represents a view of the post hole making device.

In the drawings, A designates the handle of my mallet or hammer of suitable size and B designates the head connected to the handle and composed of two parts, as shown. The head has the cylindrical body 0, having at one end the flat, flared striking face D and at the other endthe broad dished, cupped or concaved portion, or striking face E. The

. purpose of this cupped portion is to enable the maul to strike an even hard blow upon the post and effectively drive the same without injury to the post or splitting as is invari ably the case when the heavy metal mauls are used. The handlepreferably screws into the threaded opening Fof the metal strengthening bar G, which extends longitudinally of the head and has at one end the enlarged portion H, and the other end engages the end D and is arranged centrally of the cupped or concaved portion and the end D.

I use in connection with my maul or hammer the post hole making device shown in Fig. 4, consisting of the cylindrical body J having the pointed terminal K for entering the ground to make the hole and formed with the socket L, in which is placedthe post M, which is struck by the maul to drive the point to make the opening.-

It will be seen that I provide a maul or mallet which being made of wood is light in weight though very strong and durable and will drive the post without tearing the wood as is the case with the usual maul. It is also evident that I provide a device for making the post hole which is entirely efficient.

I claim-- A post or pile driver, consisting of the sectional head, one section having the enlarged cupped portion, the bar connecting and securing the two sections of the head together and the handle secured to the bar.

In testimony whereof I affix my signature in presence of two witnesses.
