latented Sept. 27, 1932 UNITED STATES PATENT OFFICE GONZALO C. IUNOZ, O1 PHILADELPHIA, PENNSYLVANIA, ASSIGNOB TO THE AMERI- CAN PULLEY COHPLNY, OI PHILADELPHIA, PENNSYLVANIA, A. CORPORATION 01 rnnnsnvam 4 mm snon Application med m 10', mo. Serial No. 451,239.

- This inventionrelates to piles useful in the formation of foundations for buildings, piers, wharves and similar structures, and it has more 5 timber variety adapted to be driven into the earth.

The primary object of this invention is to provide a shoe for timber piles more especially, such shoe being fabricated in a manner conducive of easy attachment while affording effective protection for the penetrating and of the pi e against splitting orspread- 1n 1 another object of this invention is the provision of a shoe for timber piles embodying halves which when united afford a pyramidal point with attaching means capable of easy flexure in accommodating said shoe to piles of differing diameter.

Other objects not specified at this time will later on appear, or be referred to; while the nature, characteristic features and scope of this invention will be clearly understood from the following description when con- 2 sidered in connection with the accompanying drawings forming a part hereof, and thereafter finally claimed.

In the drawings: Fig. I is a perspective view of the lower portion of a pilehaving my improved shoe attached thereto.

Fig. II is a relatively enlarged plan view of the shoe.

Fig. III is an elevation of the same, with a portion of the point broken away to better disclose otherwise hidden features.

Fig. IV is a development of one half component ofthe pile' shoe.

Fig. V is a perspective view showing how 40 the shoe attaching portions may be flexed to accommodate a pile end of lesser diameter Fig. VIII is a development of the shoe' shown in the preceding illustration.

articular reference to the heavy Fig. IX. is a plan view of a further slightly modified form of the invention.

. ig. X is an elevation of the same, with a portion of the point in section to better illustrate a different type of ti or point.

Fig. XI is a develo ment 0 one half component of, the shoe illustrated in Figs. IX and X; and,

Fig. XII is a perspective of the modified tip or point.

Referring more in detail to the'drawings, the reference numeral .1 designates a portion of a timber pile, the lower end whereof is conveniently although not essentially, shaped to a 0rd a pyramidal point 2, Figs. I and V; or, said lower end maybe appropriatel made conical, asindicated at 3 in producing pile shoes for application to pyramidal points 2, I 'firstl sever blanks B, of the form illustrated in l igs. IV and XI, fromsheet metal .such as steel, for example, of suitable width and thickness. Each such blank B, Fig. IV, it will be remarked, is of duplex formation; or more specificall said blank embodies doubg rhomboids 4, t e major dimensional edg 5, 6 whereof conveniently meet at anglesof ninety degrees, while the minor dimensional edges 7 are parallel.

It is also to be noted that the edges 7 align 8o with the longitudinal ed es of the sheet metal from which the blanks are severed, so that a succession of such blanks may be produced with a minimum of wastage. These blanks B are also, subsequently or simultaneously, provided with comparatively large and relatively small apertures and holes 8, 9, respectively, for purposes later on explained.

In the slightly modified contour of blank- B, shown in Fi XI, corresponding refer- 9 ences are applie in order to avoid repetitive description. The only differing feature has reference to the formation in said blank of an obtuse-angular point p, intervening the upper major dimensional edges 5, and a corresponding angular recession p at the lower end intermediate the "major dimensional edges 6, for pur oses later on explained.

Each'blank 1; is suitably bent medially,

or along a line passing through the angular points of the meeting edges 5, 6; or the angular points of the parts p, p; to conform with the angular relation of adjoining faces of the pyramidal Ipile point 2, as best understood from Fig. Now it will be readily understood that, when two such bentblanks B are opposedly placed and united, as by welding 10, along the abutting edges 6, there is produced a shoe S having the general appearance illustrated in Figs. II and III, or IX and X. The shoe S is of hollow rectangular cross-section insofar as the lower half or point is concerned, and also embodies-upwardly directed triangular attaching-sections or ears 11, respectively co-planar with the faces of said point portion. Attention is also directed to the fact that the apertures 8 are located substantially central of the sections 11, while the holes 9 are proximate the apices thereof. The apex of the point or pyramidal section of the shoes is preferably reinforced by an insert 12, and the tip welded at 13 to solidified formation, to counteract any tendency to disruption when penetrating the ground and encountering hard substances.

In the modified form of Figs. IX and X, instead of fitting an insert 12, as above described, I make use of a solid tip or point 12 of somewhat plumb-bob formation. More specifically, the point 12' comprises an inverted conical tip t, with a grooved extension e, about which the hereinbefore referred to angular recessions p are adapted to lap, when the blank B of Fig. XI is medially bent as aforesaid, and be united integrally in position by welding 13. Incidentally, the parts 79, p, are provided to accommodate the bending medially to semi-pyramidal or conical oontour, in an obvious manner, without drawing or contraction of the metal at said parts. In the modified form of my invention shown in Figs. VII and VIII, it will be remarked, the blank B substantially embraces the. blank B of Fig. IV in duplex, with the exception of a cut-out C, whereby there is provided four attaching sections or ears )1;

said blank B when united along the edges 6',

as by welding in the manner hereinbefore set forth, being conformable to the conical point 3 of the pile 1 shown in-Fig. VII, and thus constituting a shoe S as above explained.

The cut-out C serves to accommodate a tip or point 12' of the type described in connection with Figs. IXXII, inclusive.

Shoes S or S are attached to the complementarily configured pile points 2, 3, respectively, bydriving appropriate fastening means 14 throughthe holes 9, in an obvious manner. Furthermore, when shoes S or S are to be attached to piles 1 of less diameter than those indicated in Figs. I and VII, itwill be understood from Fig. V that the attaching sections or ears 11,11 can be readily flexed inward to conform to the circumferential surface of a pile 1, incident to pronave-1.14

vision in said sections of the apertures 8, 8. In other words, the apertures 8, 8' are provided in the attaching sections or cars 11, 11 so as to render said sections or ears more or less flexible whereby they can be readily bent I claim 1 1. A pile shoe embodying a hollow geometrically-configured penetrating portion with integrally formed attaching points co-extensive therewith, said points being apertured for the purpose of flexing.

2. A pile shoe embodying a hollow portion with geometrically-configured walls mergent into a penetrating point, said walls embodying co-extensive ears apertured for purposes of flexure and attachment, and a reinforcing insert secured in the apex of the penetrating point.

3. A pile shoe comprising integrally united opposing blanks, each said blank embodying duplex rhomboidal sections with the free angled portions apertured for purposes of attachment and flexure, and a pyramidal reinforce secured in the apex of said shoe.

4. The combination with a pyramidally pointed wooden pile of a correspondinglyshaped hollow shoe embodying opposed complemental laterally-bent sections having coextensive attaching ears, said ears being centrally apertured for purposes'of flexure and holed for the reception of-means whereby said shoe is secured to the faces of the pile oint.

V 5. The combination with a pyramidallypointed wooden pile of a correspondinglyshaped hollow shoe having co-extensive attaching ears, said ears being apertured for flexure into engagement with the body of the pile ad'oining its point for the purpose specified.

6. The combination with a pointed wooden pile of a complementally shaped hollow shoe having co-extensive attaching ears, said ears being apertured and pierced respectively to accommodate flexure and attachment to the body of the pile.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 1st day of May, 1930.
