Application filed February 24, 1909. Serial No. 479,753.

To all whom t may concern:

Be it known that I, JOHN A. Granny, a citizen of the United States, residing at Mound City, in the county of Holt and State of Missouri, have invented a. new and useful Mold for Bases for Telephone and other Poles, of which the following is a specification.

The invention relates to a mold for a base for telephone and other poles.

The object of the present invention is to improve the construction of molds, and to provide a simple and comparatively inexpensive mold, designed for molding a base for telephone and other poles, and adapted to produce a durable base of concrete, artificial stone, or other plastic material, capable of affording a maximum support with a minimum amount of material and of being easily handled in transferring it from the place where it is molded to the curing shed, and also of being readily handled in moving it from the curing shed to the place of use.

A further object of the invention is to provide a mold of this character, adapted to mold a base, which will be capable of supporting a pole some distance above the ground and out of contact with the same, so as to enable a shorter pole to be used than heretofore, and at the same time to enable all kinds of poles either wood or metal to be utilized.

Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to with out departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Figure 1 is a side elevation, partly in sect-ion, of a mold, constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

The mold comprises in its construction an outer cylindrical shell 1, constructed of sheet met-al, or other suitable material and expansible to enable it to be readily removed from around the plastic material of the base 2. The Cylindrical outer shell is secured in its closed position by al plurality of pivoted latches 3, mounted upon the outer shell adjacent to one of the vertical edges thereof and engaging keepers l, secured to the outer shell at the other vertical edge of the said shell. Each latch is pivoted at one end and is provided at its other end with a depending engaging` portion 5, and the keepers l consist of horizontal loops, arranged to receive the depending` engaging portions 5, as clearly illustrated in F ig. 3 of the drawing.

The cylindrical shell 1 is removably seated upon a horizontal bottom provided at its periphery with a cylindrical upwardly eX- tending wall 7 and having a cylindrical support S at its lower face. The wall 7 and the support S may be constructed of wood, or any other suitable material, the wall 7 forming a cylindrical socket or recess for the lower end of the shell 1. The bottom G is provided with a central opening 9 to enable it to tit over a centrally upwardly extending stationary core 10, and the support 8 spaces the bottom G from the floor 11, or other supporting surface to provide a space for an outwardly extending bottom attaching flange 12 of the core 10. The attaching flange is bolted, or otherwise secured to the floor, whereby the core ismaintained in a lixcd position.

The core 10, which is tapered upwardly to enable'the outer shell, the bottom and the plastic base sup])orted by the latter to be readily stamped from it, may be constructed of any suitable material, and it supports a detachable upper core member 13, tapered downwardly and adapted t0 form a downwardly tapered central opening at the top of the plastic base for the reception of the lower end of the telephone, or other pole to be supported by the base. The core member 13, which is fitted on the upper end of the upwardly tapered core 1.0, is provided with a central depending screw la, which engages a threaded opening 15 of the core. The upper core member is also equipped with a handle 16, consisting of a loop projecting from the upper face of the core member 13, and adapted to enable the latter to be readily unscrewed and removed from the core previous to striking the plastic base from the same.

The bottom section of the mold is equipped with eyes 17, adapted to receive `material is set.

hoisting and carrying chains 18 for enabling the bottom section with the outer shell and the plastic base to be readily raised for striking the plastic base off the core and for transferring the former to the curing` shed. As soon as the plastic base is transferred to the curing shed, the outer shell is unfastened and is removed from the molded base, which is allowed to stand on the bottom section of the mold until the The resiliency and the eX- pansibility of the outer shell facilitates its removal from the plastic material without injury to the latter. rlhe eyes are provided wit-h angularly related shanks 19, secured to the upper and outer faces of the wall Z of the bottom section of 1the mold.

The bottom section of the mold is provided at its Lipper face with a pluralit-y of upwardly projecting pins 20, arranged to receive the lower ends of the vertical tubes 2l, which are supported at their upper ends by hinged braces 22, provided with depending studs 23, arranged to extend into and interlock the bracing members 22 with couplings 24 applied to the upper ends of the vertical tubes 2l. The braces 22, which are in the form of latches, are connected at their outer ends by pivots 25 with arms 26, extending upwardly .and outwardly from the outer shell 2. IThe outer shell is preferably reinforced at its upper end by an exterior metallic band 27, or other suitable means, and thearms 26, which have lower attaching portions, are provided at their upper ends with spaced eyes through which the pivots 25 pass. he hi'nged braces are provided at their outer ends with projections 28, beveled at their upper or outer faces, and shouldered at their lower or inner faces and detachably engaged by springs 29, which retain the braces in engagement with the vertical tubes. rlie springs are 'secured to the attaching portions of the arms and extend upward and outward therefrom at an inclination and are provided a-t their upper ends with bends 30, forming inner notches to engage with the projections 2S. rlhe vertical tubes are provided at their lower ends with shoulders, formed by nuts 31, or other suitable means and adapted to prevent the vertical tubes from pulling out of the plastic material. The lower ends of the vertical tubes and the shoulders are arranged at the bottom of the plastic base and are adapted to contact with the ground to form electrical conductors, as the pole will in practice be equipped with a wire, extending upward from the metal work to its upper end to form a lightning rod. rlhe couplings 24;, which are interiorly threaded to screw on the upper threaded ends of the vertical tubes 2l, are designed to receive threaded shanks 32 of eyes 33 for enabling lifting and carrying chains 34 to be connected with the plastic base for transferring the latter from the curing shed to the place of use or other point. ln practice the means for carrying the plastic base from the core to the curing shed may consist of the said means for removing the completed base from the curing shed. rlhe eyes 33 are detachable and in practice will be removed to enable braces for the post to be connected with the vertical tubes of the base. By constructing such braces in sections, the base may be molded and handled with greater facility. The central opening through the plast-ic base renders a large base comparatively light, and while lessening the amount of material required to produce the base, also exposes the material both interiorly and exteriorly of the base and enables the material to dry and set more rapidly and with less cracking than with a solid base. The base 2 is also adapted to be stamped or branded with the pole number, while the material is in a plastic con* dition.

The base will enable old poles, which have rotted off at the ground, to be used again as it does not require as long a pole as is used when the pole is set in the ground.

Having thus fully described my invention, what l claim as new and desire to Secure by Letters Patent, is :e-

t mold for making articles with reinforcing tubes or rods, including a core, a bottom, an outer shell provided at the top with a bracing member hinged at its outer end and provided at its inner end with means for holding a rod or tub-e, said bracing member being` also provided at its hinged end with a projection, and a spring having a bend forming a recess for engaging the said projection.

ln testimony, that l claim the foregoing as my own, l have hereto affixed my signature in the presence of two witnesses.
