PATENT OFFICFQ VEHICLE-POLE.
SPECIFICATION forming part of Letters Patent No. 788,655, dated May 2, 1905.
I Application filed October 18, 1904. Serial No. 228.984.
To all whom it concern.-
Be it known that I, GEORGE A. LAMBERT, a citizen of the United States of America, and a resident of Anderson, county of Madison, State of Indiana, have invented certain new and useful Improvements in Vehicle-Poles, of which the following is a full and clear specification, reference bein had to the accompanying drawings, in w ich-- Figure 1 is a sectional perspective view of the parts of the pole partly formed and separated, and Fig. 2 a transverse section of the completed pole. I
This invention has relation to that class of sheet-metal poles and shafts covered by my application serially numbered 196,665, filed March 5, 1904; and its object is to produce a structure having the same general formationnamely, approximately cylindricaland provided with a center longitudinal bracing-web and which at the same time will be easier to manufacture in the tapered form usually given to poles and shafts, as more fully hereinafter set forth. This form of pole may or may not be used with the bent-wood heel-piece shown in my former application serially numbered 220,490, filed August 12, 1904.
The form I prefer employing of this invention consists, as shown, of two strips of sheet metal. The main part is primarily folded into a substantially T shape in cross-section, the top bar being composed of two thicknesses of closely-contacting metal, the central or stem part being also composed of two closely-contacting thicknesses and the foot flanges being composed of single thicknesses. After the sheet is bent into this form the top flanges are curled downward to form the rounded side walls a of the pole, the lower edges of these flanges terminating ust above the foot flanges b and being clamped thereto by the supplemental part or look strip 0, which is bent around the foot flanges and seamed to the lower edges of the side walls a. The strip 0 need have but a single thickness.
It will be observed that in a pole constructed as above the Web will be of double thickness and will run centrally and longitudi nally of the pole and that the side walls will packed into the spaces.
be also of double thickness, the outer thickness extending continuously across the upper side of the pole and covering and breaking the oint d between the thicknesses composin the web. The foot flanges b, the strip 0, an the seams between the lateral and the side walls will increase the stiffness of the pole, It will be observed also that a feature of importance lies in the fact that the pole may be readily tapered or curved, or both, by curving and tapering the lines of fold. The central web may be riveted together at intervals, if desired, and in order to su )port and brace the comparatively thin shell ike walls of the pole the two spaces on opposite sides of the Web may be filled with a suitable plastic material which will harden after it is I prefer employing for this purpose a suitable light substance which will become very hard when dry or baked and which will yet be sufficiently elastic to allow of a very limited vi-.
bration or flexure. I may, for example, employ a mixture of glue and sawdust, or glue and ground ooke, or cement and ground coke; but I do not wish to be limited in this respect, as any materials and mixtures might be employed for the purpose. It will be observed that a filling of this sort will not only prevent indentations and buckling, but will also prevent internal rust, whereby the pole will be very durable, as well as light and strong.
Having thus described my invention,what I claim, and desire to secure by Letters Patent, is
1. A vehicle-pole constructed of sheet metal folded 011 longitudinal lines to form a central web and rounded side walls, these side walls extending from and formed inte gral with one edge of the web and being curved around to the other edge of the web, means for permanently fastening these latter edges to the ed e of the web, and fillings bracing the side walls against the web.
2. A hollow sheet-metal vehicle pole or shaft having a longitudinal bracing-web extending through it and the spaces on each side of said web filled with a hardened plastic material.
8. A vehicle pole or shaft constructed of sheet metal folded on longitudinal lines to form a multiple-ply central web and sheetmetal side walls, and a filling of hardened plastic material bracing the shell-like walls against the central web and assisting in holding the thicknesses of material together.
4. A sheet-metal Vehicle pole or shaft folded on longitudinal lines to form a twoply central web and two-ply side walls extending from the top edge of the web and curving down to the lower edge thereof, and means for fastening the lower edges of these side walls to the lower edge of the central web.
5. A Vehicle-pole constructed of sheet metal folded on longitudinal lines to form a central Vertical web and rounded side walls, these side walls extending from and formed integral with the upper ed e of the web and being curved down to the ower edge of the GEORGE A. LAMBERT.
