. Specification of Letters Patent.- Applicaflonfiled' September'29, m. sum-minaret.

-. Pa-tesaana ei, 1911i Be -'t known that ZI,'EnwAim Morton, a

4 citizen of the'Dominionofi Canada, residing at 'Victoria, in the Provinceof British Co-' lumbla, Canada, have invented a new and useful Metal-Reinforced Concrete Pile, of

which the following is a specification.

This invention relates to a metal reinforced concrete pile in Whichthe'metal used is of such form andis so distributed "as to afford. a maximum of strength to properly reinforce the material of the concrete with a minimum of Wei ht. In'carryingiout thisidea 1 make-use 0% standard sections of angle iron or steel for the longitudinal reinorcing members, as such are notonly easier to obtain butcan be better joined together by cover angles where a greater length of the pile is required than the length of iron ob-' I tainable. In cross section of the pile the metal .is also better distributed than where rods of iron or steel are used. Outside of these longitudinal members. I. .place open mesh expanded metal through which the concrete of the outer side is effectually bonded-with that within the metal reinforcement. It must be distinctly understood that'this pile is not one wherein the strength of the 8 metal is itself sufiicien-t to bear the load ,to

be imposed upon it, and the concrete or cement is applied merely to protect the metal from corrosion; but is distinctly a concrete pile reinforced with metal to impart a greater strength under fiexure such as a pile structure maybe-ex sed 'to.

The invention is particular y described inthe following specification, reference being made to the drawings with which it is acaccompanied, in which:

Figure 1 shows a vertical section of the upper end of the pile, Fig.2, a portion of the mid-length of the pile showing the rein-.

forcing frame in elevation, and F 3, a

The drawings show the applicationof my having a jet pipe throu h. which water under pressure may be of the reinforcing'frame may be used in .a bearingpilefor driving, or in a sheet pile or other structure where similar requirements exist. 1

In these drawings 2 represents the jet-pipe extending lengthwise-of the pile, which jet pipeis connected outward at '3 toth'e side of the pile for connection to an hydraulic' pres sure service, and at 4 sred'u'ced to a nozzleand secured in the b0 t om shoe of the pile. To the up er end of'the pile is secured a bolt 5 by w liich a timber superstructuremay be attached to the Y pile, which bolt is furnished with an anchoring flange 6to afford it a secure-hold-ao-f the'concrete. Freely fit ted ongthis jetpipe 2 at intervals of approxielivered to *the lower end to sink the pile but the structure- I system of construction to a pileo'f that class mately eight feet apart are a series o f liglitY cast iron cross frames 10 which frames conform td'thecross sectionfofthe pile-but are smaller in diameter to afford the necesszu'y thickness ofconcrete outside. of the metal structure to preclude the possibility of it breaking =from*- that "structure in use. The diifiensions of the metal reinforcing frame in relation 'tothepile need not lee-according to the scale shown in the as. the

structure of the frame'i'sfsuch'asfto -bond the concrete outside of the frame eifectually with that inside the frame, gothat the-crosssection of-th'e frame may'ben uehgreaterin; proportion to the cross section-dimension of the pil'e'than is here shown. 4

The cross frames 10, the form of which'is' clearly shown in Fig. 5, have provision for the reception of angle irons 11 which extend continuously from the shoe 5' to within a short distance of the 'top, and where the length of the pile requiredis in excess of the length of .angle iron orsteel availablethe continuity is preserved by.- abutt joint and cover angles at each joint of the angle iron or ini any other a proved mann These angle irons 11 fit reely in the recesses prov1 ed' for them inthe cross frames 10 and' may be secured tightly in these recesses by wedges 12 of soft etal such as horse shoe nails by which the-angle irons are driven closely int'd the outer corners of the recesses. The cross frameszlO are-desi ed tomaintain'b'both the 'jet pipe 2 and t e longitudinal angle irons 11in osition in relation to one another. while e concrete isfeing- Around the longitudinal angle 'irons'between each pair 0f cross frames 10, open mesh expanded metal-13 is placed and is securely tied by wire at 14 to the angle irons, and at 15 to the cross frames 10 and tothe adjacent lengths of the expanded metal.

' These ties bind the expanded metal sheets to each other and to the angle irons and hold them in their respective positions while the concrete is being filled and packed. Theties 15 are of equivalent cross sectional area to that 'of the expanded metal so that the continuity of the.expanded metal is efi'ectually preserved throughout the length .of the pile.

The bottom shoe 8 is made of sheet metal in the form of a'truneated pyramid and the bottom cross frame 10 rests uponportions l6 split and inwardly bent from the sides. The cross frame is centered on its supports 16 within the shoe by metal hooks 17 screwed into holes drilled in the supports. The an gle irons 11 pass through the bottom frame 10 for a short distance and are anchored against the under side of the frame 10 by cross rods 18 through each adjacent p'air.

iVhen the reinforcing frame is complete the concrete 9 is molded thereon preferably while the frame is in a horizontal position as by that means it can more quickly and eti'ectually be packed to thoroughly fill in between the various parts of the metal structure.

The principal advantages of this method of construction, wherein angle irons and expanded metal are used to reinforce a concrete pile, are that the metal is of a form 'that is readily obtainable, audits cross sectional area is suchthatitcan be arranged that that-area is distributed toward the outside of the pile and while its surface: a'e

sufiiciently ample to afford a good surface to the concrete those surfaces are not so uniformly plane that the concrete will readily break from it, .as the'expanded metal enablesth concrete outside of the frame'to be strongly bonded with that-in the inside of the frame. I I

Having now particularly described my in yention and explained'the reason therefor,- I hereby declare that what I claim as new and desire to be protected in by'Letters Patent, is; 1. In a concrete pile, a plurality of angle irons running throughout the length of the pile, a series of spacing frames having apertures to permit passage of said angle lrons and form seats therefor, expanded metal members wound around said angle irons between said spacing frames, means fortying saidmetal members to said angle irons and to said spacing frames, :1 sheet metal shoe laterally extended to the outside diameters. of-the pile and having cut portions inwardly bent, and means for securing oneof said spacing frames to said inwardly bent'port ons. v

' 2. In a concrete pile, a plurality of angle irons running throughout the length of the pile, a series of spacing frames having apertures to permit'passage of said angle irons and form seats therefor, expanded metal members wound around said angle irons between said spacing frames, each of said spacing frames comprising an outer rectangular portion and diametrically disposed. cross portions merging with a central apertured portion and a pipe within the pile projeeted through said apertured portions of said spacing frames.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
