The present invention relates to a pile head protector, and has for its objectto pro- I vide a cheap, convenient, and durable means for protecting the heads of wooden piles I from moisture and unequal bearing and other factors which tend to cause decay, at, near or through the head.
With the above and numerous other objects in view as will appear as the descripii for supporting the cap. C. The letters D denote the drift pins. My improved pile head protectors are designated generally by the letters A. Referring particularly to one of the protectors, it will be seen that the numeral 5 designates the top plate of a nonelastic shield having a frusto-conical marginal flange 6 depending therefrom- The numeral 7 denotes the inner cushion of elastic material which is caused to adhere to the bottom surface of the shield or outer casing by a coating of bituminous material 8. The outer casing or shield is made of pressed metal, especially galvanized iron, although it may be made of anymetal or combina- 40 tions of metals desired. I This outer casing is shaped roughly like an inverted pie plate. The smaller inside diameter is equal or greater than that of the pile it protects. A number of various sizes is used so thatIany size pile maybe capped Without protruding excessively. The purpose of the outer casing or shield is to pre: vent moisture from reaching the cushion 7 and the pile head properly, because moisture which gets into the cracks and pores in the headaccelerates decay. o

painted or not, as may be a ment of parts may be resorted to without de- Iclaim as new-is:
similar material- This cushion is stuck to 66 the inside of the outer casing by pitch, asphaltic cement, or other suitable cementing material. The cushion being stuck to the. casing as a unit, allows the protector to I also tendsto preserve the cushion. The purpose of the inner cushion is to distribute the load over minor irregularities in the pile head proper, and also to assist in rendering the pile head proper moisture-proof.
The manner of using the pile head pro-- tector is as follows After'the pile is driven in place and sawed ofl' ready to, be capped, it is covered with the pile protector. The cap C is then put in place. A hole for the drift pins D is then bored through the cap, but not through the rotector as that might injure the bit or rill. The drift pin is then, driven through the hole in the cap, through the protector, and into the pile as usual. Before placing the protector on a treated pile, the head should be treated with the the pile. For instance, a creosoted pile should'be' treated with an application of hot creosote followed by tar or pitch before This treatment will make a better joint, and is desirable but not necessary, in order tomake profitable use of the protector.
The present embodiment of the invention has been disclosed in detail since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention'and the above description.
It will be apparent, however, that changes inthe details of construction, in the materials, and in the combination and arrangeparting from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what A pile head protector including an outer casing of metal comprising a circular body having a marginal depending frusto-conical flange, and an elastic cushion] within the casing and cemented thereto.
