A. R. EIGHLER. CUSHION HEAD PoR CONCRETE PILES.
APPLIUATION FILED DEO. 7, 1911.

ALBERT R. EICHLER, 0F SACRAMENTO, CALIFORNIA.
CUSHION-HEAD FOR' CONCRETE PILES.
To all whom t may concern Be it known that-I, ALBERT R. EIGHLER, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented new and useful Impr( vements inCushon-Heads for Concrete Pil-es, of which the following is a specification.
This invention relates to a cushion head for concrete piles.
It is the object of this invention to provide a cushion head for conciete piles and the like, for protecting the pile while driving.
A further object is to provide a cushion head, which is simple in construction, eilicient and durable, and which can be readily applied.
The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure l is a view in vertical section of the invention. Fig.2 is a horizontal section on the line X-X, of Fig. l.
In the drawings, A represents a concrete pile of any suitable description, and indicates the vertical guides of a pile driver, in which the hammer 2 operates upon a shoe 3 in a base Ll, in the usual manner.
My present invention resides in a detachable head which is mounted on the guides B and rests upon the pile A beneath the shoe 3. This head consists of a hard-wood block 5, conforming in cross-section tothe upper end of the pile A, of any suitable length, which is capped on its upper end with a hard rubber plate 6 and is covered on its lower end with a number of layers of soft wood 7, the grain of which is arranged transverse to the grain of the hard-wood block 5 and to the top of the pile A. The block 5 is surrounded by a metal jacket 8 which extends some distance beyond the ends of the block, in order to Surround the rubber plate 6 and the sott wood layer 7, and project a short distance therebeyond. The upper end of the Vjacket 8 receives the lower end of the shoe 3 which normally rests on the rubber plate G; and the lower end of the jacket extends over the upper .end of the pile fr, so that the end of the pile will be in contact with the lower soft wood block 7. The jacket 8 is slotted on diametrically opposite sides, with longitudinally extending Specification of Letters Patent.

slots' 9, which slots extend from the'lower end of the jacket 8 to a point adjacent the lower end of the hard-wood block 5, and are providedas a means for allowin the lower end of the jacket to expand w en placedV over the pile.
The. jacket 8 is secured to the block 5 in any suitable manner, this case showing a tapered key 10 which. extends through the.
jacket 8 and block 5, as shown in Fig. 1, and 1s retained therein by means of a nut 11 threaded on a stud formed on the end of the key.
In the application of theinvention, the pile A is set in position between the guides B, and the cushion head, which is mounted on the guides, is lowered so that the lowermost block 7 will rest on the top of the pile, the u per end of which is centered on entering t e lower end of the jacket 8 The hainmer 2, on being operatedinthe usualmannei'. delivers its bleu to the shoe 3 in the base 4, which blow is transmitted to the ile A through the hard rubber plate 6, har -Wood block 5 and soft-wood blocks 7'. 'The plate G cushions the blow of the hammer; the hard-wood block transmits the force of the blow to the blocks 7, which blocks being of softer material than the block 5 and the pile A, act as a cushion vat this point, thereby protecting the ile. The soft-wood blocks 7 become crushec after being subjected to a large number of impacts and are then re-' moved and replaced by new blocks.
Practice has shown that concrete piles, driven with the above described cushion head placed thereon, are practicall uninjured or damaged by the blows of t e hammer.
It is manifest that the pile A may be of any desired shape, other than that here shown, and that the cushion head may be of any shape conforming thereto.
From the foregoing it will be seen that I have provided a simple cushion head for piles which can be readily placed in position on the pile and removed therefrom and repeatedly used; the ortion subject to greatest wear, consisting ci) the blocks 7 being removed when necessary.
Having thus described my invention, what I claim and desire to secure by Letters Patent is- 4 1. A cushion head for piles comprising a jacket, a block inclosed in. the jacket and la metallic jacket, a hard-wood block nclosed in the jacket and se'cured thereto, said jacket extending beyond the ends of vthe block, a resilient plate on the upper end of the block surrounded by the jacket, and a layer of soft wood on the lower end of the block surrounded by the jacket, Y
3. A cushion head for piles, comprising a metallic jacket, a hard-wood block inclosed in the jacket and secured thereto, said jacket extending beyond the ends of theblock, a
resilient plate on the upper end of the block surrounded by the jacket, a layer of soft wood on the lower end of the block surrounded by the jacket, and guide-engagingv membcrsmounted on the" jacket.
4. rlhe combination witha pair of Vertical guides having `a hammer thereon, of a metallic jacket, a hard-wood block inclosed in the jacket and secured thereto, said j ackct extending beyond the ends of the block, a resilient plate on the upper end of the block surrounded by the jacket, a layer of soft wood on the lower end 'of the block surrounded by the jacket, and guide members mounted on the jacket engaging said vertical guides. v
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
ALBERT It. EICHLER.
