To all whom it may concern: 1

Be it known that we, ORVILLE Dooennnrr,

' JAMES W. ARMSTRONG, and ADAM E. ABM- srnonc, citizens of the United States, residing at the 'city of Three Rivers, county of St. Joseph, and State of Michigan, have invented certain new and useful Improvements in Molds for Artificial-Stone orConcrete Posts, of which the following is a specification. 1,; a

This invention relates to improvementsin molds for artificial stone or concrete'posts.

The main objects of this invention are:

first: to provide an improved moldfor ar-.-

tificial stone or concrete posts b the aid of which posts may be very 'read' y manufactured; second: to provide an improved mold for artificial stone or concrete posts which may be readily removed from the post after the post has been allowed to set or harden, or to artially set or harden: and third to provi e an improved device for inserting metal cores or binding-strips into a detail si jug-device, a binding-strip being indicatedin position therein by means of dotted lines;

the post during the molding operation.

Further objects, and objects relating .to structural details, will definitel appear from the detailed descri tion to 0 ow.

Y We accomplish the o jects of our invention by the devices and; means described in.

the following specification.

The invention is clearly defined and pointed out in the claims.

A. structure embodying the features of our invention is clearly illustrated in the accon i panying drawing forming a part of this I specification, in which:

Figure 1 is a detail side elevation ofour improved mold; F ig. 2 is a detail plan thereof, one end only bein shown Fig. 3 is an enlarged detail longitu inal section taken on a line corresponding to line 3-3. of Fig.

'2;;-Fig. 4 is a transverse section taken on a line corresponding to line 4'4' of F i 3; Fi 5 is an inside perspective of one of the end-plates; Fig. 6 is a detail plan of the supporting trough for the binding strips ,or.

cores for molding them in proper position to be engaged by t respondin to line 7-7 of Fig. 6; Fi 8 is deelevation of our improvedplaee placing-device; Fig. 7 is an enlarged cross-section taken on a line cor- I and Fig. 9 is a cross-section of the placingdevice, taken on a line .corresponding to line 9-9 of' Fig. 8.

Referring to the drawing, the, body 1 of our improved mold is formed of sheet metal 1 and is preferably U-shaped in cross-section,- having arounded bottom and sides flaringslightly outward; The side walls of the trough are provided with outwardly -pro-' jecting flanges 2. The molds are preferably posts. The end-plates 3 are provided with mturned flanges 4 at the bottom and the side flanges 5 being preferably formed of a sin-- gle piece of sheet metal. The bottom flanges 4 are providedwith holes 6 adapted to receive the downwardly-projecting lugs 6' 6n the body of the trough. These lugs are preferably formed by slitting the body and punching down the metal, as clearly appears in Figs. 3 and 4. I

The side flanges 5' .ofthe end-plates are provided with upwardly-projecting lugs 7 adapted to be inserted through holes 8 provided'therefor in the flanges of the body when the end-plates are in positiorrthereon. The end-plates are preferably secured in position by the buttons 10 which are pivoted to the body at 11 and, adapted to swing under the end-plates after they are placed 1n position. The end-plates are preferably rectangular so that they provide a suitable tapered to secure a suitable taper to the as p brace for holding the molds in an upright In practice, the moldsare filled and the.

material allowed to set atleast sufliciently to keep its form,- and the molds are inverted over a level surface, preferably of loose earth, as they harden more perfectly when so supported. The end-plates are then removed, when the mold maybe readily lifted from the post. This may be done without any danger of breaking or disturbing the ostmaterial,' as the walls of the body yield -,sufliciently to release the post at all points,

and, at the same time the walls are effectively'su 'iportedby the end-plates so that the posts molded therein are uniform in size.

As a convenient means for inserting the binding-strips 'or'cores into the posts, we provide an inserting device, preferably comprising a bar 17 which is substantially the same length as the core or the binding-strip to be inserted, and this bar is provided with a plurality of fingers 18, the lingers having forks 19 thereon, adapted to receive the core-strips 21. These lingers are preferably formed from flat bars, slitted at their lower ends, and the slit portions bent in opposite directions to form forks, as ClBQ1'ly'QPPGZlIS in Fig, 9. With the binding-strips thus supported throughout their length, they may be pushed into the material in the mold after it has been filled. This avoids the necessity of supporting the binding-cores during the filling of the mold, and, as the material readily'fills in around the core,

after the placing'device has been withdrawn the binding-strips are entirely inclosed.

i vVe preferably provide the tingers 18 with a gage-pins 20 so that the'positio'n of the binding-core and the concrete material may determined by the user.

To aid in readily picking up the binding strips by the placing-device, we provide a I V-shaped trough 12, the same preferably consisting of side walls and rectangular end-plates, whereby it is supported in an uprwht position.

On the inner wallsof the side-plates are rests 14 adapted to receive the binding-strips and support them throughout the length placed overthe same (see Fig. 7).

thereof; The binding-strips are held upfrom the side-walls 12 by means of the blocks readily 15 so that the placing device may be By this means, even though the binding-strips may be of flexible material, they may be quickly picked up and placed in the plastic material and held as described.

Having thus described our invention; what we claim asn'ew and desire to secure by Letters Patent, is:

1. Ina mold, the combination of a troughlike sheet metal body U-shaped in cross-section, having outwardly projecting flanges at the top; end-plates for said body, having inturned flanges at their sides and bottoms, adapted to embrace said body, the bottom flanges of said end-plates having holes there inand the side flanges having upwardly projecting lugs thereon, the flanges of said body having holes therein adapted to receive said lugs, said body having lugs on the bottom thereof adapted to engage said holes in the bottom flanges of said end-plates.

2. In a mold, the combination of a troughlike sheet metal body having outwardlyprojecting perforated portions at the top; an end plate for said body having inturned flanges at the sides thereof to embracethe sidesof the body, said flanges having outwardly projecting lugs thereon adapted to engage the perforations in said projecting members on said trough, and a button on said body adapted to engage said end plate for securing it in position on said body.

In Witness whereof, we have herenn'o set our hands and seals in the presence of two witnesses.
