MOLD FOR. CEMENT 0R CONCRETE FENCE-POSTS.

Specification of Letters Patent.

Patented Apr. 12, 1910.

Application tiled October 22, 1908.. Serial No. 459,078.

To all' whom it mag/concern:

Beit known that I, HENRY W. UNDER- Woon, a citizen of the United States, residin at Aurora, county of Kane, and State of Ilmois, have invented certain nev.7 and useful Improvements inl Molds for Cement or Concrete Fence-Posts, of which the followin is a-specificatiolr y invention relates to improvements 1n for-ms for cement or concrete fence posts; and the object of my invention is to provide a mold for readily, easily and quickly formin cement fence osts.

lther objectswlll appear hereinafter.

M invention will be more readily understoo by reference to the accompanymg drawings formin a part of this specification and in whic Figure 1 is a perspective view of a fence post mold embodying my invention in .its a wire strengthening frame for the post 1n position thereln, Fig. 2 is a similar view thereof showing the mold in opened position and the Wire strengthening frame beingA removed, Fig. 3 is a, cross section of the mold as illustrated in Fig. 1, Fig.` 4 is a similar view of the nioldas illustrated in Fig. 2, and Fig. 5 is a cross sectional view similar to that illustrated in Fi 3 and showing a' modified form of mold. Y j

Referring now tothe drawin s B indicates the mold which is of a sing e piece of. 'galvanized sheet metal 5, the latter being of a resilient character for reasons whichfwill be hereinafter described`. Said mold vis formed' octa onal in cross section and taper ing longitu inally, the same being open at both ends. The eight sides of the mold are formed integrally, the contiguous longitudinally extending edges 6 and 6 of the same being Vadapted to be overlapped. The edge portion 6 1s providedupon its outer surface, close -to the edge thereof with a longitudinally extendin angular met-al 'strip 7 preferably secur'e by rivets 8 thereto. Between the off-set 4'edge portionv 9 of said istrip 7 andj'the outensurface of the edge portion 6, theedge .portion 6 of the mold is adapted vto rest when the device is in use, that is, is in closed shown in Fig. 3. In or er to facilitate holding said form in Vclosed position when inuse as stated, I provide -the edge orton V8 thereoflwith "ailurality 'of late thereto and horizontally the ob osition, fas clearly rods 10 projecting therefrom. Said latch rods are each provided with a number, preferably two, of notches 1l vin its lower edge, said notches being adapted toengage a pi-n 11 projecting from and formed integrally with a backing 12, the latter being secured as by rivets 13-to-the edf portion 6'of the mold. The outer face o the backing 12 is in a plane Witlr'the face of the portion 6 when the mold is closed, and the portion 9 is notched as at 9 to ermit the latches to pass therethrough, see ig. 2. By this construction the mold B which, because of itsresilient character is normally held in an opened position, as shown in Fig. 2 may 'readily be held 1n closed position, as shown in Fi 3. When in the last named position', the e ge portion 6 of the mold rests against thereof, as clearly shown in Fig. 3, said edge being beveled to insure a snug t. When iquely disposed adjacent surface 14.-4

about to fill the mold with the plastic cef ment or concrete, the .contiguous edges of the same are forced together, that 1s, are overlapped as before described and as shown in Fig. 5, the same being latched in position. The lastic cement or concrete which is filled 1n from the top having set, in order to remove the same, that is the fence post, the latches are disengaged, whereupon the'mem- .ber 5' because of its before mentioned resili en cy will open of itself, thereby freeing the vpost contained within.

In order to provide the fence post with transversely extending wire receiving per- 'forations, I provide opposite sides of the' member 5 with aseries of perforationsl? -preferably arranged in pairs therein, as

shown, and for a purpose `hereir'iailter described. Through said perforations areinserted rod members 18, whicl1, after the cement has set are withdrawn thereby ob'- viously forming said transversely extending perforations through the ost. Said mem ers a loop 19 at one extremity thereof to facili- -tate'readily withdrawing the same from the device. In Fig. 5f is. shown a, modifica-tion of this.- feature, the rod members 18 in which case are obliquely dis osed in' themold the same restin in per orations 20 provided vin walls o the mold disposed at right angles to each other, Vthere y forming obliquely extending perforations in the fpost, 11,0 upon the withdrawing, of the same.

Having described my invention what I 18 are preferably each ormed with- .thereof being a Ywhen in position. or molding, an angular. secured adjacent to oneedge thereofan ada notched claim as new 4and desire to secure by Letters Patent is:

' o -sheetv material and oned along one side,

.tedio said member beingl res ent and ada normally stand ogen, the lon 'tudina edges a ted to overlapped pted to receive the opposite edge tch bars pivot lly secured to said other' edge, fa members secured to 'the gller face of mold afgcent anar strip, ins projecting m sai acn members adapted to be engaged by sai latch bars, and said angular .strip being notchedor recessed to receive said latch bars, substantiall as described.

2. A mol of the class described 'compris- `in close octagonal tubular member formed o sh eet material and o ened along one side, said member being rsi ient and 'ada ted to normally-stand o of said member lapped when in position or' molding and the inner ed e being beveled to form a snug joint with te adjacent oblique side, an angular strip' secured ad'acent to the inner edge ofthe mold and a apted to-receive Ithe outer edige, and means :Eer locking said mold position, substantially as described. 'Intestlmony whereof I have signed my name to this specification in the presence vof two subscribing witnesses.
