REMOVABLE PILE FOR FORMING CONCRETE PlLlNC-I..
SPECIFICATION forming part of Letters Patent No. 756,805, dated April 5, 1904.
Original application led January 13, 1903, Serial No. 138,921. Divided and this application filed February 3, 1904. Serial To @ZZ whom t may concern.-
Beit known that I, FRANK SHUMAN, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Removable Piles for Forming Concrete Piling, (the same being a division of my applicationQSerial No. 188,921, filed January 13, 1903,) of which the following is a specification.
My invention relates to that method of forming piles of concrete or cement which consists in first driving a preparatory pile into the ground, then withdrawing said preparatory pile and filling the opening formed thereby either during or after such withdrawal with plastic concrete or cement, which when it becomes set will form the permanent pile.
The object of my present invention is to provide a preparatory pile of this character with a point which can be removed independently of the pile and can be collapsed or decreased in diameter, so as to be removable without forcible contact of its sections with the walls of the opening formed by the pile.
My invention is especially applicable to piles having enlarged points, such as shown in my Letters Patent No. 733,286, dated July 7, 1903, although not specifically limited to such enlarged points. i
ln the accompanying drawings, Figure 1 is la vertical sectional view illustrating my improved pile as the same appears while it is being driven. Fig. 2 is a similar view showing withdrawal of the pile; and Fig. 3 is a transverse section on the line a a, Fig. 1.
The pile shown and described in my former patent consisted of a metal tube 1 or a solid pile of wood or metal' provided at the top with a suitable driving-head 2 and at the bottorn with a point which was of so much greater diameter than the pile 1 that the latter would not come into contact to any material extent with the walls of the opening formed bydriv-l ing the pile, the point being of greater diameter than the pile itself, so that the frictional hold of the earth in driving the pile is restricted to the limited area presented by the expanded point, with the result that the pile could be driven to any desired depth without (No model.)
unduly increasing the frictional hold of the earth upon the pile and could also be withdrawn with the exercise of a relatively limited amount of power.
My present invention consists in providing the pile with a point composed of sections movable one in respect to another, whereby said point can be collapsed, and therefore withdrawn from the opening without bearing forcibly upon the walls of said opening, or can even be withdrawn through the hollow pile itself before the w ithdrawal of the latter, if desired. As shown in tliedrawings,the point consists of three sections 3, 4, and 5,each of' these sections being in the present instance in the form of a segment of a circle, as the point is of circular cross-section, although, 'of course, the shape of each segment will vary as the section of the point varies. Each of the sections of the point is connected by a chain 6 to' a crossbar 7 in the hollowpile 1, the chains being of different lengths, so that as the pile is withdrawn from the opening, as shown in Fig. 2, the sections will be successively detached one from another and lifted one by one with the pile from the opening. By increasing the number of sections in the point each of the latter may be so small as to be capable of withdrawal through the hollou7 pile 1 .after the latter has first been withdrawn suiiiciently to permit of the separation of the sections one from another, the chains 6 in this case extending to the upper end of the pile, so as to be within easy reach. My invention is, asl will be evident, applicable to pile-points which are not of greater diameter than the pile itself, although especially intended for use in connection with points of the latter character.
Having thus described my invention, Iclaim and desire to secure by Letters Patent-- 1. A removable pile having a detachable point with sections movable one in respect to another, whereby said point can be collapsed or contracted.
Q. A removable pile having a detachable point with sections movable vertically one in respect to another or others, whereby the point can be collapsed or contracted.
3.v A removable pile having a detachable lIo point with independent sections, and connections leading; to the. interior et' the pile, Whereby these seetions een be movofl, one in respect to another, to collapse or.' Contract the point.
4. A removable pile having' a deteeheble point composed of independent and separable sections, and connections between each of these sectionsc end. the pile, seidv connections being' of different lengths, whereby, es the pile is Withdrawn, it will withdrew the seetions of the point in Succession.
5.- A. iemovelile pile lie-ving an enlarged and detachable point with sections movable one in respect tok another, wlleieby said. point een be collapsed or connected.
6. A removable pile having en enlarged and detachable point with sections, movable vertieelly one in respect to another, or others, whereby the point een be collapsed or contreated.
v(lenteolieble point composed of mlependent and separeble seet1ons,'zmcl connections l'letween each of these sections and the pile, seid eonneetions being of Llierent lengths, whei'eby, as the pile is withdrawn, it vill withdraw the sections of the point in succession.
ln testimony whereof l have signed my neme to this specification in the presence of two sub seriloing witnesses.
FRANK SHUMAN. Witnesses:
