MOLD STRUCTURE. APPLlcAfxoN FILED 1uLY6,192o.

MOLD STRUCTURE.
Application led July 6, 1928.
To all w 720m t may concern:
Be it known that I, HAnoLD J. Bieler, a citizen of the United States of America, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful improvements in Mold Structures, of' which the following is a speciiication, reference being had therein to the accompanying drawings.
This invention relates to molds for forming blocks, tiles, bricks, slabs, and other articles from concrete or plastic material, and more particularly material which in its plastic state may be poured or run into the mold.
My invention aims to provide sectional or knock down molds which are maintained in superposed tiltable relation, the superposed or stacked formation of the molds permitting of a large number of molds being stored or used in comparatively small floor space and thus increase the capacity of ,a small factory for making various kinds of concrete structures. rlihe tiltable relation of the molds permits of easy access being had to the same so that the molds may be poured or filled and thus eliminate individual manipulation of the molds and thereby save considerable time.
My invention further aims to provide strong, durable and inexpensive molds that may be used on a factory floor and especially on cars, the latter permitting of the molds being moved from a pouring station to a kiln or seasoning station, each equipped with means for manipulating the molds, as will hereinafter appear.
Reference will now be had to the drawing, wherein- Figure 1 is a longitudinal sectional view of the molds in superposed relation and showing a portion of one of the molds in elevation and tilted;
Fig. 2 is a plan of the same;
Fig. 3 is a cross sectional view oi the mold structure;
Fig. e is a perspective view of a mold bottom plate;
Fig. 5' is a perspective view of a mold side plate; and
Fig. 6 is a perspective view of a mold pivot post.
Molds in accordance with my invention are arranged in superposed units and each unit comprises two parallel channel bars 1 having the ends thereof provided with pivot posts 2 and rest posts 3, said posts being Specification of Letters Patent.
Patented Apr. 26, 1921.
Serial No. 394,078.
secured to the outer walls of the channel bars 1. rlhe pivot posts 2 have inwardly projecting vertical fianges i with the lower ends of said anges bearing on the channel bars 1 and the upper ends of said lianges constituting supports for the adjacent superposed mold unit which has its channel bars 1 loosely pivoted, as at 5 to the upper ends ot the posts 2 so that the channel bars 1 may rest on the upper ends of the flanges l. The opposite end of the superposed unit normally rests on the upper ends of the posts 3, so that the units are normally in panallelism.
The mold structure comprises a plurality of bottom plates 6 having depending flanges 7 notched, as at 8 so that the flanges 7 may be seated on the channel bars 1 and held against lateral displacement in one direction. rlChe bottom plates 6 have upstanding end flanges 9 and said bottom plates are placed in spaced relation so that side plates or partitions 10 may be mounted on the channel bars 1 between the flanges 7 of the bottom plates, said partitions having notches 11 corresponding to the notches 8 and for the same purpose.
At the ends of the bottom plates 6 and the partitions 10 are longitudinal side walls 12 and these walls are held against the ends of the partitions 10 by the upstanding end flanges 9 of the bottom plates 6. Engaging the ends of the side walls 12 are `end walls 13 having end iianges 14: engaging the outer sides ot the walls 12 and said end walls are notched, similar to the flanges 7 and the partitions 10, so as to fit on the channel bars 1. One of the end walls 13 abuts the pivot posts 2 and the other end wall 13 is in spaced relation to the rest posts 3 to accom moda-te a wedging member 15. The inner edges of the rest posts 3 are beveled or inclined, as at 16 so that the wedge member 15, which may be conveniently in the form of a pipe or tube, may be forced downwardly between said posts and the end of the mold structure, thereby causing all of the plates, partitions and walls to frictionally engage each other and be firmly held so that the molds of each unit can be lled with concrete or other plastic material.
The end flanges 9 and the. end walls 13 have been shown as means for conveniently preventing accidental displacement of the mold walls and partitions during the use of the mold unit, but it is obvious that tie rods, clamping devices and the mechanical equivalents thereot may be utilized tor maintaining the mold parts assembled.
By reference to Figs. l and 3 it will be noted that the lined ends ot the pivot posts 2 are cut away to provide clearance tor the pivot ends of said posts, and with the unta superposed, as shown in Fig. l, it is possible to raise the free ends oi said units so that easy access may be had to the individual molds of other units. Assuming that the molds are empty and are to be lilled all or the superposed units are raised at an anale so that a pouring spout may be inserted over the lowermost horizontal unit and the mol-ls thereof filled. After this pcuring` opere. on the adjacent s'uperposed unit is lowered on to the filled unit and it is filled. rlhis if; continued until all ot the molds are loaded. As stated in the beginning, this may be conveniently accomplished by in@` the-mold units at one station and *ien moving` 'gl mold units away to a iiiln or seasoning sea.- tion so that other units may be also lo However, it is possible to maintain the mold units at one place and provide a movable pouring spout, and in either instance a. derrick or other means is employed for ing and loweringv the free ends ot the mold units.
It is thought that the utility oit my mold structure will be apparent without further description, and while in the drawingY there is illustrated a preferred embodiment ot my invention it is to be understood that the structural elements are susceptible to such `variations and modieations as tall within the scope o the appended claims.
What I claim is z- 1. A mold structure comprising superposed mold units normally in parallelism and having pivoted ends and tree ends so that the iree ends may be raised and lowered to permit ot access being had to cach mold unit.
2. A mold structure as characterized in claim l, wherein pivot pests and rest posts support the superposed mold units.
A mold structure comprising parallel superposed bars, posts carried by said bars and supporting adjacent superposed bars so that said bars may have ends thereof raised, and molds on said bars.
4L. mold structure charactr-zrized in claim 8, wherein said molds are Aformed by bottom plates, partitions, end and side walls.
5. i mold structure comprising` saperposed tiltable mold units connected and supported by posts, a plurality oli' lnioelt4 down molds for each unit, and means beM tween soin-e olf said posts and said molds maintaining said molds assembled.
G. il. mold structure comorisng supelposed ti table bars, posts coni A supporting1 said bars, bottom plates :fitted on said bars, aartitions fitted on said bars between said bottoni plates, side and end walls inelosing` said bottoni plates and said partitions, and means maintaining said plates, partitions and walls assembled relative to said bars to form molds.
7. A mold structure as characterized in claim G, wherein an end wall of said molds abuts some ot said posts, and wedge members are interposed between the other end wail ot said molds and the other posts to hold the molds relative to said bars.
