MOLD FOR Posrrs.

Specification of Letters Patent. 'P'dtg'h'te d 1 910.

Application filed September 4, 1909. Serial No. 516,236.

T 0 all whom it may concern:

Be it known that I, VILLIAM T. lllCKS, a

citizen of the United 5tates,-'residing at:

Bloomington, in the county of Monroe and State of Indiana, have invented certain new and useful Improvements in Molds for Posts, of which the following is a specification.-

My invention relates to an improvement in molds or formers for molding or forming a post or column from concrete, Portland cement, shale, or clay of the form shown in an application filed by me of even date here with, Serial Number 516,235 and it has for its object the production of a machine of this character in which such posts or columns may be expeditiously and economically constructed, and the material from i which the post is built up is molded or; formed by mechanical means requiringxthe i tion of metal to the depth of the out, the

minimum of manual handling.

'ith these ends in view my invention con sists in certa n constructions and arrangements of parts hereinafter fully described and pointed out in the appended claims.

In the accompanying drawing illustrating my invention and. in which like numerals designate the same parts wherever they occur, Figure 1 is a central longitudinal section. Fig. 2' is a section taken on line 2, .5 of Fig. .l and Fig. Z'l-is a fragmentary perspective view of the lower end of the rotating packer. l designates a supporting table which, as shown, is provided with an opening i"), and

(3 is a pair of journal boxes mounted on op posite sides of the opening in the table, and

T are a pair of trunnions extending outwardly from opposite sides of the tube 8 which forms the mold. These ti'unnions 7 are mounted in the journal boxes 6, so that the mold tube=can be swung in a vertical or horizontal position.

The tube 8 is slightly tapered from its upper to its lower end, and at its upper end the tube is flared, as shown at 9, to facilitate the filling of the mold. The lower end is closed by a cap 10 which, preferably and as shown, is screw threaded on the end of the tube. .\t the lower end of the tube I provide a. concaved dish 11. which operates to give the proper shape to the upper end of the completed post, said disk having a shaft 12 projecting from the rear face thereof, which shaft extends through a central opening .in the head it), and on its other end, which is exterior thelt ube; is "proruled with a head 13, "By forcing thehead 13 inward thepost, after the same has been molded, can be loosened fro nthe'tiibe, "so

that it may be readily removed,

l t is a vertical bearing which in'jline with the axis of thc'inold tube'w ithe tube is vertical, as shown in Fig. '1. lntlli s hearing is journaled a shaft 15, said shaft having a drive pulley l6 splined tot-lie shaft, whereby the shaft can ,nioi'fe vertically through the bearing and the drive pulley. The shaft at its lower portion is provided with a helical web or screw l7,'s a1d screw being'tapered to correspond to'the t'apr of the mold tube and is of a size to fit loose in the tube. lit the termination of the s an l I secure a disk 18 having openings 19 fprmed therein by making in the periphery of the disk and turnitfg np'tlie p'o'rturncd up portion 20 being preferably turned 'up at an angle, and the slits being so made in the disk that the turned up por tions 20 will operate to force the material through the slits in the plate and then ride over the materialto pack the same down.

Preferably and as shown the tube 8 is not circula r but is provided with a flattened side it which extends from thesmaller. end of the mold anyil'esired distance, in order that the post molded by the machine will have a Hat face for the purposes fully set forth-in my companion application above referred to. I

From the foregoing description of the construction of my apparatus it will be seen that when the tube is placed in vertical position with its larger end upward the shaft 15 can he slid down into the tribe until thedislt 11S reaches the ejector disk 11. Thein'ol te'fial from which the post is to be m'adis now "fodintoth'e mold and thesliaft 143 rotateddna direction to cause the screw tov force the material downwardly and out.- wardly. The material will be radually forced through the slots 19 in the c islilsby theturned up wings its the operation is continued the screw will be gradually forced out of the tube until finally the'tilbe has been completely filled with the material from which the post is made, By using the construction described all parts of the post will be'even'ly and expeditiously packed, so that when the tube has been completely filled the shaft is moved up to be I now be turned on its trunnions either upside out of the way, and the tube can down or into a horizontal position, and by means of the'ejector 11 the molded post can vhe forced from the tube.

-What Iclaim as'new and desire to secure by Letters Patent is opening, and extending 1 at disk, one of said cated'on opposite sides of the op and the-like, the combination with a tablehavingan opening therein, journal boxes 10- ening, a mold tube provided with trunnions, said trunnions being mounted. in the journal boxes, a shaft, a helical web on the shaft, said shaft being' movable. into said tube, a disk mountedon'the end of the shaft at the end f the helical web, said disk being provided with openings, wings extending up from the Wings being located at one edgeof each opening, and extending at an "angle-to the disk, and means for rotating the .shaft.'

3. In a machine for molding fence posts and the like, the combination with the mold tube, of a shaft having a; helical web on one end thereof, said shaft being movable longitudinallyin the said tube, a disk mounted on the end ofthe shaft-at the end of the helical web, said disk being provided with openings, wings extendin up from the disk, one of said wings being%ocated at one edge of each opening, and extending at an angle to the disk, means for rotating the shaft a concaved ejector disk mounted in the an of the tube and having a stem pro ecting outside of the tube.

at. In a machine for molding fence posts and the like, the combination with the mold tube, of a shaft having a helical web on one end thereof, said shaft being movable longitudinally in the said tube, a disk mounted on the end of the shaft at the end of the helical Web, said disk being provided with openings, wings extending up from the disk, one of said Wing's being located at one edge of each 'dpening, and extending at an angle to the disk, and means for rotating the shaft, a portion of one side of said tube being flattened.

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