9 Application .filed April 28,
To all whom it may concern:
Be it known that I, PAUL J. Hown, a citizen of the United States, and resident of Ridgewood, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Apparatus for of which the following is This invention relates to improvements in apparatus for piercing timber, and has for its general object the provision of means for rap1dly and economically piercing, or. formmg holes or incisions in, the surface of wooden timbers, such as railway ties, pilin structural timbers, fence posts, telegrap and telephone poles, and cross-arms for tele graph and telephone poles, preparatory to a liquid pre- Other objects of the invention are to provide a' piercing apparatus having a multiplicity of piercing teeth so constructed that it may be easily and rapidly shifted over the surface of a timber; to provide a piercing implement having a toothed rolling element and power-operated impact means so constructed and arranged that the impact means may be utilized to simultaneously rotate or advance the toothed element along the timber and force the teeth thereon into the timber; and to provide a oweroperated .multi-toothed piercing e ement which may be readily manipulated 011 either sawed, hewn, or round timbers to form holes or incisions over the entire surface area thereof or any desired portion of the surface of the timber.
A further ob'ect of the invention is to provide a simp e'and eflicient power-actuated piercing device which may be readily 1 adapted to economically practise the method of treating timber described in the patent to Goss, No. 1,252,428, Qated Jan. 8, 1918. In the accompanying drawings- Figure 1 is a side elevation, partly in vertical section, of one form of apparatus-embodying the invention; v

Referring to the drawings by numerals, 1 deslgnates the casing or cylinder of an ordlnary fluid-pressure operated hammer in whlch is mounted a reciprocating piston or hammer head 2. Th with the usual hand and the usual bushin tool socket, or chuck 4; at its lower end. The usual valve 5 and operating trigger 6 therefor are provided for governing the supply of .fluid under pressure to the piston cylinder.
A tool shank 7 is threadedor otherwise rigidly held in the socket or chuck 4. The upper or anvil end 8 of the tool shank 7 is adapted to be struck by the hammer head 2, as the head rapidly vibrates in the cylinder 1, to transmit the blow or impact of the hammer to an axle or shaft 9 supported in a yoke or fork 10 formed on the lower end of the shank. The blow of the hammer head is transmitted to the axle 9 transversely of the axle.
Various forms and sizes of rolling elements, having any desired form of teetharranged in irregular or, any desired relatlon, may be mounted on the axle 9. In Flgs. 1
and 2 a solid cylindrical roller 11 is shown,
I 14 may be arranged regularly or irregularly may be of any desired form. As shown, these teeth are of diamond shape in crossand section and relatively wide 'at the base circumferentially of the roller and narrow longitudinally of the roller, as more clearly 6. This form of tooth, when the machine is moved length wise of the timber, forms holes or incislons primarily by a spreading or wedge action which opens up the surface fibers with little or no severing of the individual fibers. I have shown the teeth 14 arrangedin spirally or diagonally. extending rows with t e teeth of each row spaced short distances apart longitudinally intermittently advance and arrest the piercof the rollers and the rows of teeth spaced inghead.
