GEORGE A. LAMBERT, OF ANDERSON, INDIANA.

VEHICLE-POLE.

SPECIFICATION forming part of Letters Patent N o. 788,654, dated May 2, 1905.

Application filed August 12, 1904. Serial No. 220,490.

To @ZZ whom, t nto/ zj 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 being had to the accompanying drawings, in which- Figure 1 is a perspective view of a pole construcied according' to the preferred form; Fig. 2, a detail perspective view of the heel portion detached; Fig. 3, a horizontal sectional view through a part of the fold adjacent to the doubletree bearing; Figs. 4, 5, and 6, cross-sections of the pole, showing various forms of sheet-metal structures.

`All-wood vehicle-poles are becoming more and more expensive to manufacture each season, as suitable hickorywood is becoming scarcer and scarcer.

It is the object of this invention to permit the utilization of smaller, and consequently cheaper, pieces of the wood to be employed. thus reducing the expense of manufacture to a considerable extent.

In my improved pole I make the bent heelpiece a of wood in the usual manner; but instead of making it integral with the main or straight part of the pole I make it separately therefrom from a comparatively short piece of wood and attach it to a sheet-metal pole its forward end being inserted in the rear hollow end of the pole and fastened therein. The metal pole is constructed of folded sheet metal. I prefer constructing the main part of the pole of a single sheet of metal folded on longitudinal converging lines to forma central web portion c of two or more thicknesses of metal, as shown in Fig. 4, and oppositely-extending flanges of two or more thicknesses at the upper and lower edges of the web portion. These thicknesses of metal are fastened Atogether in any suitable manner, preferably by rivets passed through the thicknesses composing the web portion. 'Ihe sides of the channel-iron or I-beam thus formed are bridged over the full length of the fold by shells f, semicircular in cross-section, giving the pole the` desired shape in cross-section.

The longitudinal edges of these shells are seamed to the longitudinal edges of the flanges d, thus forming' a very rigid and light pole having a pleasing and substantial appearance. This metal part of the pole can be formed Very inexpensively with the proper dies, inasmuch as it is a simple tapering structure without curves.

Instead of constructing the pole in the manner shown in Fig. 4 and above described I may construct it in a variety of ways. Two of these modifications are shown in Figs. 5 and 6. In Fig. 5 the web and flanges are formed of three sheets of metal properly folded and riveted together, the iianges d being of Asingle thicknesses in the web o or three thicknesses. In Fig. 6 the same structure is shown, except that the shells f are expanded at the seam, so that their outer surfaces become iiush with the outer faces of the flanges Z/ and form a substantially continuous surface, giving to the pole a more regular oval shape in cross-section. i

The wood heel has its forward end g made straight and slightly reduced in diameter, so as to lit tightly in the hollow pole. Its end portion g is slotted vertically for the reception of the central web c, and it is fastened in its socket by any suitable means, preferably by the same bolts /t which fasten the bracerods to the sides of the pole. If additional fastening devices are necessary, the bolts 1.', which fasten the doubletree bearing-plate j to the pole. may also be utilized for this purpose. In some constructions the hammerstrap bolts may also be made to perform the additional function of securing the two parts of the pole together. As shown, the thicknessess composing' the central web aie slightly spread apart for the passage of the bolt c', whereby the bulges thus formed on the exterior of the central web will be forced into the wood of the stem g. The doubletree-bolt /c may also be used in a like manner if found desirable.

It will be observed that in the manner set forth in the foregoing a strong and durable pole having as pleasing an appearance as the all-wood poles may be constructed ata greatlyreduced expense in comparison with the all- IOO wood poles, as the comparatively short wood pieces required for the heels can be obtained in large quantities at little expense.

It will be understood that I am not confined in my claims to the exact construction of heel-piece and metal part shown and described, and I therefore reserve the right to vary the construction without departing from my invention. For instance, it might be desirable to construct the straight part of the pole partly of wood instead of entirely of metal, this being within the spirit of the invention, as is obvious, and also that the rear end of the metal part of the pole may terminate short of the king-bolt of the doubletree, so that the lateral bulges shown in Fig. 3 (which would interfere with the insertion of the tongue portion g) shall be done away with.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is#

l. In a vehicle-pole, the combination of a straight metallic forward portion and a bent wooden heel portion attached to the rear end thereof.

Q. In a vehicle-pole, the combination of a bent wood heel portion and a straight metal pole proper hollow at its rear end, the for.- ward end of the heel portion being straight and inclosed in said hollow part.

3. In a vehicle-pole, the combination of a hollow sheet-metal pole part proper and a bent heel portion having its forward end straight and inclosed in the rear end of said pole part proper.

4. In a vehicle-pole, the combination of a straight pole part proper formed of sheet metal folded and made hollow, said hollow part being braced by an internal longitudinal web, a heel portion having its forward end inserted in said hollow pole member, and means for fastening the parts together.

In combination with a curved wooden heel portion having a straight forward eXtension slotted longitudinally` of a metal pole part proper made hollow and provided with a central web, the straight part of the heel l portion being inserted in the rear hollow end of the pole proper and fastenedtherein.

6. In a vehicle-pole, the combination of a curved heel member and a straight front portion, said front portion being constructed of a central web having top and bottom anges and shells seamed to the respective top and bottom fianges, whereby the straight portion of the pole is made hollow, the forward end of the heel portion being inserted in the hol- Alow portion and fastened therein.

7 A vehicle-pole having its main forward part constructed of longitud inaliy-folded sheet metal and its rear or heel portion of wood, substantially as set forth.

8. A vehicle-pole constructed of sheet metal folded on longitudinal lines, the folds being brought together to form a multiple-ply central web and also top and bottom flanges, and separate sheet-metal side walls connecting the flanges on each side.

9. A metallic vehicle pole or shaft consisting of a central longitudinal web provided with lateral iianges, and metal side walls attached at their Lipper and lower edges to said flanges.

10. A metallic vehicle-pole consisting of a folded sheet-metal central web and separate lower edges to the respective upper and lower edges of the web.

ll. A sheet-metal vehicle pole or shaft consisting of a multiple-ply central web and top and bottom lateral iianges, and single-pl y side walls attached to said anges.

12. A sheet-metal pole consisting of a central web part provided with top and bottom iianges, and side walls or shelves seamed to said flanges along their longitudinal edges.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 9th day of August, 1904.
