' STANDING CONCRETE-POST roam.-

T0 all whom, it may concern: H I r 7 Be it known that 1, JOHN L. 'MoGEE, .a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Standing Concrete- Post Forms; and I "do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to Which it appertains to make anduse the same. v I

My invention relates to improvements in concrete post forms, and has particular reference to that type that are adapted to be secured tothe ground over the post holes in an upright position prior to the pouring of concrete therein for the purpose of molding the posts.

An important object of my invention is to provide a device of the'above mentioned character which consists of a pair. of coacting semi-cylindrical sections constituting the form of my improved construction, and means for anchoring the form inoperative position carried by each of said sections.

A further importantiobject of my invention is to provide a device of the above mentioned character which is constructed of few parts, simple and reliable in its operation, and cheap to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in {the claims which are appended hereto and form a part of this application. f -v With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figurel is a sideielevation illustrating the form in assembled posltion. Fig. 2 is a vertical sectional view illustrating the form in operative position over the post hole and showing the concrete therein partly in section to illustrate ;the' reinforcing elements embedded in the concrete. Fig. 3 is a transverse sectional view taken on line 3-'-3 of Fig.1 and illustrating the hingedcon- Specification of Letters Patent. I

Patented Dec. 1,1914. Application filed July 23, 1913. Serial Njo. 780,840.

Referring now to the drawings forming.

a part of this specification and in which like numerals are employed to designate like parts throughout the same, the numerals 1 and 2 designatethe semi cylindrical sections which are slightly tapered toward their lip-.

per ends and are hingedly secured at certain of their longitudinal edges by means of a plurality of. cars 3 formed in alinement upon the-longitudinal edgesof each ofthe sections, and a pin L extending longitudi-.

nally through each ofthe ears 3.

.Eachof the sections 1 and Qare'provided upon their longitudinal freejedges with a plurality of outwardly extending tongues 5 which are disposed in spaced relationship to each other fto provide a plurality of laterally extending. recesses. 6. The recesses of each oftlie sections are adapted to receive the tongues-5 which are spaced from the provide a plurality of apertures .7 in which a wire, tie 8 1s adapted to be inserted. The

vwire ties 8 are' inserted within the apertures 7 in such a manner as to allowvthe illustrated inFig. 2, or a plurality of hooks,

designated 11 and shown in Fig. 1.,

In order to prov de for the anchoring of the forifi operative position over thepost hole, ,the sections 1 and 2 are each provided with a plurality of spaced radially [extendupper and lower edges of the recesses to ing plates lQeach of which are provided with an opening 13 at their/outer terminals to. facilitate for the insertion of a spike 14 which is adapted ,to be drivenfintoi; the ground 'aboutthe post hole. When it is desired to reinforce the 'concretepos taplue rality i of vertically disposed reinforcing rods 15 are mounted within the form in spaced relationship tov the sides thereof prior to the pouring of the concrete into the form. ,Jlhe ,upper terminals of each of, the ysections 1 and 2 are bent to provide the rounded portions 16 in order to facilitate for the formation of a rounded, concrete post, and are recessed to provide an opening 17- when the. sections are in operative, posi;

7 each of the rods, as this invention providestion to provide for pouring of the concrete therein.

When reinforcing rods of greater length than the sections and post hole are used, provision is made for the proper spacing of a plurality of notches or recesses 18 arranged in spaced relationship about the opening 17 at the upper terminals of each of the sections that are adaptedto receive "the rods whereby the desired effect may be Thad, and when the concrete is poured into the form the rods are driven through the soft concrete and into the post hole and flush with the top of the concrete within the form.

The manner of operating the form in "connection with forming the fence posts 'i'nay' be briefly described as follows: The

forms are arranged in a line over the fields in which-a plurality of post holes have previously been dug, in vertical position over 'the post holes, and when it is desired the sections areswung open to allow for the insertion of the reinforcing bars after the manner described, and the sections are locked after the manner described, whereupon the next step is to anchor the sections in operative position over the post hole,

and this is done by driving the spikesl l. I through the openings 13 formed in the plates 12. The concrete is then poured into fjhetop through the opening 17 into the wire tires 8 are inserted within the apertures step is to drive the rods through the soft {concrete into the post hole and ground therefbeneath until the upper ends of the reinforcing bars are flush with the-top of the concrete within the form. The forms are left standing upon the field until the con- ]crete has hardened sufficiently, and are then removed. p willthus be seen that a form for concrete posts is provided which will accomplish all the functions hereinbefore cited in a reliable and expeditious manner.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above descriptiomas the preferred'einbodiment, is

the most efficient and practical; yet, realizingthat the conditions concurrent with the ,fadoption ofmy device will necessarily vary,

tudinal edge of one of said sections, the otherof said sections being provided with a plurality of laterally extending recesses at its free longitudinal edge, said tongues inserted within said recesses and being smaller than said recesses and adapted to hold a wire tie between said tongues, said sections having their upper extremities rounded and provided at the edges thereof with. spaced inwardly extending recesses.

2. A form for concrete fence posts com prising a pair of semi-cylindrical sections, said sections being hinged adjacent certain of their longitudinal edges, a plurality of spaced tongues formed upon the free longitudinal edge of one of said sections, the

other of said sections being provided with a plurality of laterally extending recesses at its free longitudinal edge, said tongues inserted within said recesses and being smaller than said recesses and adapted to hold in wire tie between said tongues, said sections having their upper extremities rounded and provided at the edges thereofwith spaced inwardly extending recesses, and means for locking the sections in assembled position.

3.'A form for concrete fence posts com prising a pair of semi-cylindrical sections,

spaced tongues formed-on. one longitudinal edge of one of said sections, spaced recesses formed on one longitudinal edge of 1 the other of said sections, a plurality of integrally formed laterally extending spaced securing flanges formed onthe lower portions of each of said sections, said sections being rounded at their upper extremities,

the edge of said rounded portions being provided with recesses and means for locking the sections in assembled position.

In testimony whereof I ailix my signature in presence of two witnesses.
