CONCRETE PILE FOLLOWER A N D METHOD OF MOUNTING SAME.
Application tiled September 30, 1920. Serial No. 413,866.
My invention relates to improvements in concrete pile follower and method of mount; ing the same, and has for 'its object the construction of a strong, reinforced concrete pile member adapted to be mounted upon the top of a wooden pile member in the cheapest and most effective manner.
more general object of my invention is "to unite the multipleor composite sections 0 of a''pile structure by partially telescoping a relatively long connecting metallic sleeve over the unprepared end of a wooden pile member securely to unite a second pile member thereto through the sleeve by a driving and shearing fit of the metallic sleeve.
Hitherto a most important objection obtaining against composite piles has resided in the necessity for more or less accurately fitting and fastening the two or mo-re members together. Moreover, certain types of such composite piles have the inherent disadvantage of presenting sections of'marked difference in diameter wherethe members are joined.
My present improvements seek to avoid these and other disadvantages, while affording an exceptionally strong and serviceable connection between the different Vmembers and. in effect, carrying the attachment of the concrete reinforcement'back to the wooden pile member. Moreover, by adopting substantially the construction herein disclosed and the procedure of mounting the same, which I shall outline, it is entirely unneces- 35' sary to shape the wooden pile member. Thus the driving of piles equipped with my improved follower is much more expeditiously and cheaply accomplished than with any other composite pile known to the art.
I mav firstbriefly explain the concrete pile follower by stating that it comprises essentially a4 relatively long, met-al sleeve and a concrete body of any desiredlength precast therein. In practice,l of course, it is usual 4to provide reinforcement and the reinforcing members or systems preferably` are directly attached interiorly of the metal sleeve by welding thereto. tapering expansion pin is provided within thebase of the concrete 4member and protru es a d ist-ance therefrom within the sleeve. Instead of fitting the follower and wooden pile together. I merely drive the latter approximately to the ground level or water line, .then apply the tubular sleeve to the top of the wooden pile and drive the follower .inforcing rods Optionally, a
to a fit thereon by telescoping the sleeve over the end of the wooden p1le, and finally driving the composite pile thus produced, to its full depth.
My invention and improvements may be more fully and explicitly set forth by maklng reference to the accompanying drawings, wherein;
Figure 1 is a view principally in vertical section, illustratin the pile follower and the upper portion of t e wooden pile; both memers, however, being brokenaway.
ig. 2 is a transverse section through the corcrete pile follower on line 22, Fig. 1, an
Fig. 3 is a somewhat diagrammatic view intended to illustrate the method of mounting the pile follower, showing the members in position for uniting them.
Throughout the several figures of the drawings I have` employedthesame character of reference to indicate similar parts..
Describing first, with more detail, the reinforced, concrete pile follower of my inven-- tion, I may explain that the tubular shell or sleeve a is formed of any.v suitable metal, such as steel, bronze or the like, to adapt it for the particular use intended. 'Ihe reb are interiorly welded within the upper portion of the sleeve and an associated system of reinforcement c and the tapering expansion pin d are all positioned as shown prior to the c'astingof'the concrete body e within and above the sleeve. It will beunderstood thatthe nature and amountl of reinforcement will be designed and adapted for the length and size of concrete follower which is to be constructed and Ildo not wish to be understood as in any waylimiting myself to the details somewhat dlagrammatically shown and herein referred to, except as they are set forth in the claims.
ese concrete followers naturally will be made of different diameters approximating the butts of the -wooden piles'f with which they are intended to be used. Accordingly, when the wooden pile fA has been driven to nearly its full length, one of my improved concrete pile followers, having a sleeve approximating, but preferably of slightly smaller ipterior diameter than the exposed butt, is 'then placed y in position thereon end to end, a pile cap 1s placed upon the head or butt of the concrete follower and the pile driving is `re-4 sumcd. Care should be taken to insure the initial telescoping of the seleeve fora short distance over the end of the wooden pile so that the members will be joined securely by a shearing it in substantial alinement. Thereupon, the composite pile may be driven in the usual manner and to the full depth desired.
If the tapering expansion pin is used, this will serve somewhat to spread the upper portion of the butt within the sleeve, while a thin, irregular shell f usually is shaved from the upper portion of the wooden pile f, exteriorly of the sleeve. By' reason of the direct attachment of the reinforcing system to the long, telescopin sleeve member a, the composite pile thus formed is practically unitary from a mechanical standpoint and the wooden butt is adequately protected by the sleeve which firmly encases the same. Moreover, when the sleeve is driven below the surface of the ground or beneathithe bed of the waterway, the wooden pile member is protected thereby from the more common sources of damage and deterioration.
My improved method, involving the production of precast, reinforced concrete members, permits cheaper and more careful construction than when the concrete is poured in place. Again, the work quite obviously can ,proceed with much greater rapidity and certainty of result than with the older methods. The independent anchorage of the reinforcing' members, effected by welding, riveting or otherwise suitably .securing them to the sleeve, although this frequently may be found unnecessary in practice, adds an important factor to the strength and durability of the composite pile. A factor of still greater importance and novelty, however, resides in the economical and time-saving method of making the pile follower self-fitting, by shearing with its metallic sleeve the exterior extremity of a substantially unshaped wooden pile for accomplishing a rigid telescopic union therewith.
Having now described the preferred mode and means for practicing my invention, I claim as new and desire to secure by Letters Patent, the following:
l.
