To all whom it may concern:
Be it known that we, ALEXANDER GIBB, THOMAS GRAHAM MENZIES, and ROBERT CHALMERs, civil engineers, subjects of the provide apparatus for withdrawing quickly and economically piles, posts, poles, and the like fromthe position into which they have been driven.
According to existing methods piles have to be pulled or prized from their position necessitating a resistance or fulcrum against which to apply the re-action from the force used. In some cases so great a force is necessary that owing to the absenceof a suitable resistance or fulcrum against which to work, such force is incapable of practical application.
According to this invention an attachment is provided. for fixing to the pile which is to be withdrawn, WhlCh attachment is adapted to receive the blows of a pneumatically or otherwise'operated hammer. The hammer is by preference separately supported, but it may be carried on the pile itself, either directly or by means of an attachment for that purpose, or-it may be carried on the same attachment which is adapted to receive the blows of the hammer or it may be supported by a combination of these means. Thus the only. resistance or fulcrum required is that necessary to support the hammer and overcome the re-actlon from the blows, and the resistance necessary for this purpose is onlya fraction of what is required according to existing methods as described above. It is for this reason that the hammer, sup orted directly or otherwise on the pile Itself, and
' without any external support, will draw, or
partly draw the pile. The blows of the hammer will preferably be delivered in quick succession, and a plurality of hammers operating simultaneously may if desired be employed.-
The accompanying drawings illustrate this apparatus in several of the methods in which 'it may be employed.
In Figure 1 the hammer is shown working entirely supported-by the separate support. In Fig. 2 the hammer is supported rom the pile itself by means of an auxil iary cylinder and piston. In Fig. 3 the hammer is shown supported by a combination of the external support and the auxiliary cylinder and piston resting on the pile.
In Fig. 4 the hammer is shown supported partly by the external supportand partly by a sprmg. This spring may be eit er in a position in which it supports the hammer from the piles itself, or in a position in which case it supports the hammer from the attachment adapted to receive its blows. With either position or both positions of the spring, the hammer may be used either with or without the externalpull. Fig. 5
represents the hammer carried directly 'on the pile. .This method may also be combined with the external support which may be applied to the casing of the hammer, or to the attachment or. to the pile itself.
Fig. 6 a plurality-of hammers,.in this case so four is shown. Fig. 7 is a sectional plan view indicating the positions of the hammers.
hammer on the anvil o. The hammer on hammers'd (2 may be operated by the .action of steam or compressed air on a piston e in a cylinder f. Distance pieces g. are
shown keepingthe cylinder at such adis-' tance from the anvil c as will insure the hammer operating through its normal stroke. The separate support for the hammen is represented by the chain and rods k h on which a crane may be employed to a represents the pile and b the attachment thereto adapted to receive theblows of the'i 85 In Fig.
I 6 the hammers are supported on s rings k k which in turn rest upon the attac ment Z Z, to the pile a.
The hammer conjunction with the withdrawing means usually employed will be found to greatly assist such means in withdrawing the pile.
What we claim and desire to secure by Letters Patent of the United States is 1. In apparatus for withdrawing piles and the like, an anvil, means for attaching the same to the pile, a hammer and means for operating the same to strike the anvil in the proper direction substantially as described.
'2. In apparatus for withdrawing piles and the like the combination with the ordinary withdrawing means, of an anvil ator hammers when used in' tached to the pile and a vibrating hammeractuated to strike the anvil in the proper direction substantially as described.
