POLE BUTT Leonard Hartley, Mount Shasta, Calif.

Application August 17, 1945, Serial No. 610,892

2 Claims.

This invention relates to improvements in polebutts, and has particular reference to a butt to be attached to bases of poles such as telephone and electric light poles.

The principal object of this invention is to provide means for attaching the base of the pole to a reinforced concrete butt, Which butt is that portion which normally is imbedded in earth in order to support the pole in a vertical position.

A further object is to produce a device of this character which will accommodate poles of different diameters.

A further object is to produce a device which is economical to manufacture, readily installed and one which may be easily and quickly applied to the mold form so as to become an integral part of the pole-butt.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same.

Fig. 1 is a cross sectional view of a pole-butt, with my invention applied thereto, and showing the mold sections.

Fig. 2 is a side elevation, partly in cross-section, of a completed pole-butt, and pole secured thereto.

Fig. 3 is an enlarged top plan view of my invention, and

Fig. 4 is an enlarged detailed cross-sectional view taken on the line 44 of Fig. 1.

Ordinary poles such as telephone and electric light poles usually have their lower ends imbedded in earth, the result being that due to moisture, the portion of the poles so imbedded will be destroyed by rot, or be eaten by the various wood-attacking insects, and it is customary to remove such poles and replace them with new poles, or install a short end of a pole adjacent the original pole and secure it thereto; such short poles being known as pole-butts,

I have, therefore, devise a pole-butt which is cast in reinforced concrete and has attached to the upper end thereof a securing means whereby the end of the original pole, or any pole, may be readily attached thereto, thus eliminating the necessity of replacing the same with an entirely new pole, and at the same time my device eliminates the contacting of the pole with earth.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a reinforced concrete pole-butt which is cast in a mold of any desired construction. Here, the mold is shown as a divided mold, and consists of portions 6 and I.

My invention consists of a metal ring 8 which fits within the mold sections 6 and l, which ring is provided with an outwardly extending flange 9. This flange is, in turn, connected to an upstanding ring ll of larger diameter than the ring 8, thus forming a funnel-like structure, having an internal ledge, the purpose of which will be later seen.

Spaced about the inner circumference of the ring II are U-shaped partitions l2, which partitions extend from the ledge to the top of the ring II, thus forming bolt-receiving spaces l3; the bolt holes being shown at M.

The result of this construction is that when my funnel-like structure is placed in the top of the mold and the mold is filled with reinforcing rods and concrete, the concrete will overly the ledge, or upper surface, of the ring 9, and thus tie the device firmly to the reinforced concrete butt.

After the concrete has hardened and the mold sections are removed, the butt may be placed in the earth and the bottom of the pole positioned thereon and secured thereto, through the medium of straps l6, which have outwardly turned ends H, which engage bolts [8 extending through the bolt-receiving spaces and through the bolt holes M.

It will thus be seen that solid connections can be quickly and easily made between butts and poles.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention vor the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A reinforced concrete pole-butt having a pair of coaxially arranged rings positioned on above the other and at the upper end thereof, said rings being connected by a flange forming a ledge underlying a portion of said concrete, and means for securing the lower end of a pole to said rings, said means including bolts secured to said pole and positioned adjacent the upper of said rings and engaging the lower surface of said flange.

2. A reinforced concrete pole-butt having a pair of coaxially arranged rings positioned one above the other and at the upper end thereof, said rings being connected by a flange forming a ledge underlying a portion of said concrete, means for securing the lower end of a pole to said rings, said means including bolts secured to said pole and positioned adjacent the upper of said rings and engaging the lower surface of-said'flange, and a plurality of partitions secured to the upper of said rings and extending to and engaging with said flange to form bolt-receiving spaces.

LEONARD HARTLEY.
