Specification of Letters Patent.

Patented ean, 1913.

Application filed February 17, 1911, Serial No 609,170 Renewed February 24, 1913. Serial No. 750,415.

To all whom, it may concern:

Be it known that I, ROBERT M. Jones, a citizen of the. United States, residing at 1142 Humboldt street, having oflices at 805 Ideal Building, Denver, county of Denver, State of Colorado, have invented a new and useful Process of Forming and Making Concrete Poles, Piles, and Columns, of which the'following is a specification.

This invention relates to the process of forming concrete -into cylindrical form, either solid concrete from its center to its surface, or formed around an internal core to its surface, including ample provision for embedding reinforcing steel longitudinally in and through the cylindrically formed article, all to be accomplished without the aid of an exterior form or mold.

This process of forming reinforced poles, piles and columns without the use of exterior forms, I accomplish by enveloping concrete in a heavy flexible belt material, the belt to be somewhat longer than the article to be formed, and in width equal to twice the circumference of the article to be formed in its largest part. The forming of the concrete into a round cylindrical form is accomplished by revolving themass of concrete one or more revolutions slowly up and down an inclined plane, ohcausing the belt,

and mass to be formed, to revolve one or more revolutions alternately in one direction thence in the opposite direction upon and encircled in a series of rollers having approximately the same size and shape of the article to be formed. In either or anyv event, the belt and the surfaceof the article being formed of concrete shall travel throughout the length of the article being formed, at proportionate velocity, thereby preventing a twisting or torsional movement'of the mass of concrete while it is in the process of being formed. For forming tapered articles such as poles, the proportionatequantity of concrete will be distributed to cause one end to be larger than the other. In such instances the enlarged diameter of the work must be driven at proportionately greater velocity, by. such procedure articles fnay be formed having forced concrete poles, piles and; columns upon which I have submitted to the United States Patent Oflice this day an application for patent.

Together with this, my application for patent upon Process for forming reinforced concrete poles, piles and columns, I submit drawings (one sheet) illustrating two applications of the process.

In the drawings, Figure 1, represents a perspective view of an apparatus preferably employed in the practice of my, process, with the mass of plastic material in the po sition it occupies while being molded, and, Fig. 2, a view in perspective of unmodified construction of the apparatus, likewise showing the plastic article in the position it occupies in the practice of my process.

Fig. 1 is described first, wherein, A represents the article being formed, which revolves or turns in the belt B as the belt is raised or lowered. B represents the flexible belt material which envelops the' article inclined plane upon whichthe flexible belt B and article being formed will travel in a revolving manner. v Fig. 2 is described second, wherein, D

represents the article being formed, it revolves upon and in the flexible belt E in unison with the travel of the belt E and rollers F. E represents the flexible belt material which envelops the article bein formed,-'it rests upon and revolves simu taneously with rollers F, the belt E terminates at either side with a weighing down strip. F represents a series of rollers built practically of the same diameter and taper which the article formed shall rep resent when completed. These rollers partially encircle the article being formed and are to be operated by gears of even ratio causing all rollers represented to revolve at the same velocity and in the directions represented by indicating arrows.

I claim class described, consisting in imparting to a body of plastic material, a revolving motion by reciprocatory movement of a surface upon which it is loosely supported.

2. The process of molding-articles of the class described, consisting in imparting to a direction transverse to said axis.

r and Whose opposite end is 4. The process of molding articles of the class described, consisting in imparting to a body of plastic material a revolving motion about a longitudinal axis by a reciprocating movement in a direction transverse to said axis, ofthe free end of a sagging, flexible surface upon which it is loosely supported,

fixed.

5. The process of molding articles of the class described, consisting in embedding a core in a body of plastic material, imparting to the latter a revolving motion in a direction transverse to the axis of said core, by movement of a surface upon which it is loosely supported, and removing the core after the material has become hardened.

6. The process of molding articles of the class described, consisting in embedding re inforcing devices in a body of plastic material and imparting to said body, a revolving motion by movement of a surface upon which it is loosely supported.

7. The process of molding articles of the class described, consisting in imparting to a body of plastic material of longitudinally decreasing cross-sectional area, a revolving motion about its longitudinal axis by move ment of a surface upon which it isloosely supported, transverse to said axis at rates of speedvarying at different points of the said surface in ratio to the circumferences of said body at the said points.
