CONCRETE-POST MOLTDQ Patented May 30,1922.

Application filed June 24, 1920. Serial No. 391,393.

Molds, of which the following is a specification.

This invention relates to new and useful improvements in molds for cement posts; the primary object of the invention being to provide a device of this nature which may be easily and readily removed from the post shortly after the same has been poured sov that the mold may be immediately used for the formation of other posts; thereby obviating the loss of time which results from the use of ordinary molds wherein it is necessary to permit the mold to remain around the post until the same has been set and hardened.

Another object of the invention is to provide the device oftheabovenaturewhich embodies a construction rendering it possible to remove the mold from the postas set forth above and without the necessity of lifting or moving the post from the position in which it was poured.

Another object of the invention is to provide the edges of the mold with reinforcing strap or irons which besides performing their well known functions also provide relatively broad top and bottom edges for the mold whereby a trowel or shovel may be engaged therewith and may be moved therealong to finish the post, the reinforcing straps also serving to properly support the mold and to provlde a novel mounting for a latch.

A still further object of the invention is part of the application and wherein like numerals are employed to designate like parts throughout the several v1ews Figure 1 is a top plan of the invention.

taken on the line 44 of Figure 3.

Figure 5* is a transverse section through the mold and cement post therein.

F1gure6 is anenlarged fragmentary longltudinal section of one end of the mold taken on the line 66' of Figure 2, and;

Figure 7 are views of wire fence hole forming elements. o

Referring to the drawings wherein for the purpose of lllustration is shown the pre ferred embodiment of my invention, the;

numeral 8; designates my improved mold in it entirety, and by viewing Figures 1 and 5 it will be apparent that the mold is pro vided with an open top and bottom so that the mold may be removed from the newly formed post shortly after it has been poured, tamped and finished, without it being necessary for the operator to lift or convey the post from the time it is poured until the time it is set and completed.

The mold consists of a pair of side walls 9 and 10' and a pair of end walls 11 and 12. These walls may be constructed from anykind of desired materiaLbut the body portions thereof, I preferably constructfrom wood to insure the mold of lightness so that it may be readily and easily conveyed from one place to another; Each longitudinal edge of the side walls has secured thereto a Tangle iron or strap l3 which ex tends longitudinally of the side to reinforce the same as well as to properly support thernol'd and to form connections between the Zontal arm of the T-arm is securedto the longitudinaledge of its respective side wall in a manner to dispose the vertical arm ll of the T-arm' inengagement with the outer face of its respective side so that it may be.

secured thereto by fastening elements 15. As will: be se'en,- the side walls gradually converge toward one end so" as to provide a mold which will form an upwardly tapering post.

The top and bottom edges of tl ie' endwalls 11 each have secured thereto, a rein forcing strap 16-, the ends of' each extended beyond the ends of the end wall as clearly seen in Fig. 6; The relative inner" edges of these straps 16 as well as the inner 95 Y walls of the same". One half of the horiends 17 of the horizontal arm of the T-irons 13 are flush with the inner surfaces of the mold walls, while the outer edges of these straps and T-irons extend well beyond the outer surfaces of the walls to facilitate connecting the walls to one another. A pair of bars or straps 18 are fastened to the inner faces of the outwardly extending portions of the T-irons and are connected to corresponding extending ends of the straps 16 by means of bolts. 20. The. ends '19 of the straps 16 are provided with a plurality of apertures 21 so that when it is desired to make the vbase of the concrete post wider, the bolts 20 may be removed and associated with the outermost openings 21 in the straps 16.

Referring to Figures 1 and 6, it will be seen that the opposite corresponding ends of the straps 16 are cut away as shown by the numeral 22 so that the arcuated extended ends 23 of the T-irons 13 of the side wall 10 may be pivotally connected by bolts 24 to straps 25 secured to the extended portions of the straps 16, thereby facilitating the inner end surface of the wall being disposed flush with the outer end of the wall 11 when the mold is in position to retain the concrete.

The opposite end 12 of the mold has secured to its top and bottom edges a pair of straps .26 which are extended beyond the ends of the body portion of the end 12. The straps 26 are cut away at one end in a manner identical with the straps of the opposite end and are pivotally connected to the T-irons 13 of the side wall 9 by bolts 27. The opposite ends of these straps 26 are provided with a plurality of apertures 28 for cooperation with a latch which will be presently described. As clearly shown in Figures 1 and 4, ornamental elements 29, in the present instance being a pair of arcuated plates are secured adjacent the upper ends of the two side walls and their free edges abut with the bottom of the end 12 so that the top of the post formed by the mold will have a pair of its upper edges rounded.

Referring more particularly to Figures 3 and 4, it will be noted that one end of the side wall 10 is extended beyond the T-irons 13 to abut with the free end of the end wall 12. The vertical arm 14 of the T-iron 13 associated with the opposite edges of the side wall 10 are extended with the side wall and rolled back upon themselves toform bearings 30 which receive the free oppositely directed ends of a resilient'latch loop 31. The inneredges 32 of these rolled portions or bearings converge outwardly of the side wall to form the rolled portions into cam bearings so that when the resilient glatch loop isswung outwardly of the side wall, the arms of. the loop will engage the cam surfaces and cause the free ends of the loop to move inwardly so that they will be out of engagement with the apertures 28 in the end wall 12. It will be seen that the side walls 10 may swing outwardly of .the mold proximity with the side of its associated wall which permits the free ends of the loop to move outwardly of each other and through aligned apertures 28 in the straps 26. This 7 of course locks the walls of the mold together so that there is absolutely no possibility of the concrete forcing the walls apart.

'In order that fence wire openings may be provided in the posts formed by the mold, each side wall is provided with a plurality of aligned apertures through which are passed a plurality of hole forming devices 34 as shown in Figure 7 These elements are passed through the aligning openings 33 in the two side walls before the concrete is poured into the mold and after the same has been completely filled, and.

finished the elements 34 may be removed. leaving a transverseopeningthrough the concrete mold. I lVhen it is desired to finishthe concrete post openings with linings, the mold is filled up to the lower edges of the openings 33-with concrete. After this has been done a plurality of sleeves are interposed between the sides of the mold so that their openings align with those disposed in the sides of themold. Pins 36 or othersuitable means are then passed through the openings in the sides of the mold which align and also through the sleeves 35 whereby they are maintained in correct position in the center of the post being formed. More concrete is then poured into the mold after which it is tamped to pack the same around the sleeve and after the mold has been completely finished the pins 36 are removed and the sleeves 35 are left imbedded in the concrete post. Therefor, it will be apparent that besides forming linings for the. openings, the sleeves also reinforce the concrete post to a certain extent.

The foregoing description and the accompanying drawings have reference to the preferred. or approved embodiment of my invention. It is to be understood however that such changes may be made in construction and arrangement of parts,'materials, dimen sions, etc., as may prove expedient andfall. within the scope of the appended claims.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. A post mold including side and end walls, one end wall having its opposite sides extended and provided with apertures, a resilient latch carried by one side wall for cooperation with said apertures, and cam means cooperating with the latch for causing the same to move to disengage and engage said apertures.

2. A post mold including side and end walls, one end wall having apertures therein, reinforcing straps extending along the edges of one side wall, the corresponding ends of the strap being formed into cam bearings, and a resilient latch having its free ends received in said bearings for cooperation with the apertures in the end wall.

3. In a post mold including a plurality of walls, one end wall being pivotally connected to one side wall, and ornamental elements secured to the side walls and adapted for engagement with the end wall when the walls are in cooperative relation.

4. A post mold including sides and ends, pivotal connections between the sides-and ends at a pair of diagonally arranged corners of the mold, and adjustable connections ment of the latch;

6. A mold comprising a pair of spaced side sleeve adapted to be positioned between the side walls with its opening alining with the alined apertures in the side walls, and its means extending through the apertures in the side walls and the opening in the sleeve for retaining the latter in position with respect to the mold.

in said bearings for cooperawill be operated by the cam bearings upon move-.

In testimony whereofI affix my signature in presence of two witnesses.
