POST-MOLD.

Specification of Letters Patent.

Application filed November 25, 1913. Serial No. 803,029.

To all whom it may concern Be it knownthat I, OSCAR G. WEED, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of .Missouri, have invented certain new and useful Improvements in Post-Molds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My inventionrelates to apost mold, and more particularly to an apparatus for molding concrete fence posts, or the like; the principal object of the invention being to provide forms for receiving concrete, or the like, through longitudinal openings, together with means forclosing the forms after the material has been poured thereinto. I

It is also an object of the invention, to provide supporting means whereby the individual form members are mounted, vand whereby the forms may be rocked to settle the concrete before the forms are closed, in order to secure a dense and compact post structure.

In accomplishing these objects, I have provided improved details of structure the preferred forms of which'are illustrated in the accompanying drawing, wherein Figure I is a perspective view of a series of post molds and their supporting and closing mechanism; some of the end plates being removed for better illustration. Fig. II is an enlarged perspective view of a plurality of molds for forming posts of different cross-section, and illustrating the cross-section more in detail; the molds in this section being illustrated in their open position. Fig. III is a similar view, showing the molds closed and sealed. Fig. IV is a detail perspectiveof a portion of one of the mold racks. Fig. V is a detail view ,of the end of the mold showing the end platemounting.

Referring more indetail, to the parts :1 designates standards having longitudinal connecting bars 2, and having pins 3 proj ecting inwardly from near their upper ends and provided with depending chains 3.

5 designates a rack having pins 4: at its ends projected into links of the chains 3, so that the rack is suspended from the upper portions of the standards and adapted for a presently be described.

swinging movement that will facilitate the settling of material in the molds, as will The detailed construction of the rack preferably comprises a single U-shaped metal bar, the body portion of which extends between the end mom bers 1.

Each apparatus comprises pairs of supports 1 and racks 5, in order that the opposite ends of the mold forms may besup ported on the racks as illustrated in Fig. I.

Supported on the body portion of each rack is a seatmember 6, comprising individual seats 7 resting on the body of the rack, and alternate seats 8 supported above the rack by webs 9; the entire seat member being preferably formed from a single piece, with the concaved seats of proper diameter to receive the base and upper ends of post molds 10, when the latter are arranged therein with the base ends of alternate molds arranged at opposite ends of the'apparatus.

Each of theforms 10 comprises a sheet metal body adapted" to form a post of desired cross-section, and having edge lips 11 turned from the body portion ofthe mold,

so that they lie in a horizontal plane when the form is mounted in the apparatus.

Fixed on each of the lips 11 is a bracket ?atentedApr.6,1915.

projection through an aperture 15, in a closing bar 16; thepins' 13 on opposite lips of each of the molds being turned'in opposite directions, so that the pin on one of the lips may project into anaperture in the bar 16 and'the pin on the otherlip into the like aperture 17 of a separate bar 18.

Pivotally mounted on the bar 16 is a handle member 20 having a plurality of apertures 21therein, and pivotally mounted V on the bar 18 is a link22having apertures 23 therein. A pin 24 projects through registering apertures in the handle member and link and pivotallyconnects the parts, so that when the handle member is moved backwardly, the bar 16 is forwarded and the bar 18 retracted to draw the lips of a mold together; and close the feeding port;

permit the sides to flex freely;

bars at each end of the apparatus, in order to obviate strains and insure complete closlng of the apparatus.

In using the device, I usually place a number of the mold forms in the racks, with the ports at the top, and open, as illustrated in Figs. I and II. With the molds so arranged, concrete is poured into the longitudinal ports in the various molds until the latter are filled. The handles 20 are then drawn backwardly to draw the lip portions of the molds together and close the feeding ports. With the ports closed the clamps 29 may be applied to the lips 11 to hold the molds closed while the concrete sets and hardens. In order to settle the material within the molds, the racks may be rocked on their pivotal mountings to shake the material and compact the fluid mass before the molds are closed and sealed.

It is apparent that molds of any suitable cross-section may be provided, in order to form posts of corresponding cross-section, and that while I have illustrated but one form of rack, this form may be varied to meet the requirements of the particular shape of mold which is to be carried therein.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is

1. A post mold having a longitudinal opening and having laterally directed lips at the edges of the opening, bars connected with said lips, and means for operating said bars to close the mold.

2. A post mold comprising a single piece of sheet metal having its free ends spaced to provide a longitudinal opening and having reinforcing lips at the opposite edges of the opening, brackets on said lips, separate bars connected with said brackets, and a single handle member for simultaneously reciprocating said bars in opposite directions, to close the mold opening.

3. A post mold comprising a single piece of flexible sheet metal having its free ends spaced to provide a longitudinal opening and having reinforcing lips at opposite edges of the opening, brackets on said lips having oppositely directed pins, bars having apertures therein for receiving the pins, a handle on one of said bars, and a link connected with the other bar and with said spindle, for the purpose set forth.

A. A post mold comprising a single piece of flexible sheet metal having its free ends spaced to provide a longitudinal opening and having lips at opposite edges of the opening, brackets on said lips having oppositely directed pins, bars having apertures therein for receiving the pins, a handle on one of said bars, and a link on the other bar adjustably connected with said handle, for the purpose set forth.

5. A post mold having a longitudinal opening, means connected with said mold at opposite edges of the opening for closing the same, and a clamp member having right angularly turned ends adapted for lateral application to the mold to retain the same in closed condition.

6. A post mold having a longitudinal opening and having laterally directed lips at the edges of the opening, means for closing said mold, and a clamp member having right angularly turned ends adapted for lateral application to said lips to hold the mold. closed.

7. In a post mold, suitable supports arranged in spaced relation, racks swingingly mounted on said suports, seat members mounted on said racks and having alternate seats of different diameter, and post molds supported on the base of said seats.

8. In a post mold, a plurality of molds, a

suitable support, a rack carried by said support and comprising a U-shaped bar, a seat member mounted on said bar and comprising a single bar having seats shaped to the configuration of the molds and alternating in large and small diameters, with the smaller seats having integral Webs projecting from the shaped seats and engaging the base of the U-shaped bar.

9. In a post mold, the combination with standards, of chain links suspended from said standards, racks having pins projected laterally therefrom into links in said chains, and molds supported by said racks.

10. In a post mold, the combination with spaced standards, arranged in pairs, of link members suspended from the upper portions of said standards, racks having pins projecting laterally from their upper ends and into said links, and mold members carried by the racks.

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

OSCAR G. WEED.
