WILLIAM H. BARTEN, or GORDON, nnnnas aa.

arrana'rosron MAKING ooncianrn enooiis.

To all'wiiom itmay concern L" Be it known that I, VVILLIAMII. BARTEN, a citizen of the United States, and a, resident of Gordon in the county of Sheridan and State of Nebraska, have invented certain new and useful Improvements in Apparatus for Making ConcreteBlocks, of which the following is a specification, referencebeing hadto the accompanying drawings.

This invention relates to improvements in the'process and apparatus of making concreteblocks.

Qne object of the invention is to provide an apparatus of this character in which the blocks may be formed from a very wet, slushy mixture, thus insuring the perfect slacking of the cement and forming when set,'a dense, waterproof,, a1':tificial stone for architectural or other purposes." 7

Another object isto'provide an improved construction of mold having a plurality of removable partitions, whereby blocks of different sizes and shapes may be formed, and

- having means whereby the finished blocks may be readily removed therefrom.

A further object is to provide means whereby the finished blocks may be em ployed for forming a large number of other blocks at one operation. v

With these and other objects in view, the invention'consists OfQQItEllIl novel features ofconstruction, combination and arrange- .ment of parts as will be more fully described and claimed, it being further under stood that changes in the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification andin which like numerals of reference indicate similar parts in the several views, Figure 1, is a perspective view of my improved mold in position for being filled. Fig. 2, is a central vertical longitudinal sectional view. of the same.

Fig. 3, is a vertical cross-sectional view taken on the line 3, 3 of Fig.2. Fig. i, is a detail perspective view of one, of the partitions of the mold shown in Fig.1. "Fig.5, is a plan view of one of the block facing plates which form the bottom of the mold. Fig. 6, isa longitudinal section of the same. Fig. 7, is a detail perspective View of one of the frames for connecting the facing plates with the ejectorbar. Fig. 8, is acentral vertical" longitudinal section of the mold in an in- Specification of Letters Patent.

Fig. 9, is a detail perspective view blocks in the mold. Fig. 10,-is a similar view of a hollow block formed by the mold. Fig. 11, is 'a similar View of a half-tile block formed by a mold.

In the embodiment of the invention, 1

verted position showing the manner in which the finished blocks are ejected therefrom.

'of one ofthe core blocks forming hollow i provide a mold 1, comprising a frameof any the lower edges of the endsare formed inwardly projecting guide lugs 8, the purpose of which will be hereinafter described.

Adapted to be arranged in the mold are a series of removable partitions, whereby the mold may be divided into a plurality of compartments, so that more than one block may be formed. Thepartitions may be consti'ucted and secured in the mold in a number of different ways. In the principal figures of the drawing. theymold is shown as constructed of sheet metal and when so constructed partitions 9, are. provided. These partitions have on the upper ends of their side edges laterally projecting lugs 10, which are engaged with notches 11, formed in the upper edges of the sides of the mold. On the lower ends of their side edges the partitions are provided with right angular apertured lugs 12, with which and with holes 13,

in the" adjacent parts of the sides of the mold areengaged fastening bolts 14, whereby the partitions arereinovably secured in position in the mold.

The bottom ofthe mold is in the form of i a series of facing plates 37 which form the faces or, outer surfaces of the blocks and which are preferably reversible, having one with either a depressed or embossed design, which will form-either a depressed or embossed design on the face of the block when the plates are arranged with the design facesthereof uppermost in the mold. When side smooth and the otherside provided f smooth'faced blocks are desired the smooth 7 sides of the-plates are arrangediuppermost in the mold.' The plates 37 have on their edges around the smooth si'des thereof anar row rim or flange 38, which when this side i of thefplates are. up will form rounded or beveled corners on the smooth faces of the blocks, V e V e @The. bottom plates 37 are spaced a siiiiicientdistance apartto receii e the partitions.

end frames are bolted to the facing plates .37, and'the ejecting bar39, by separate bolts through as shown; said bolts having their Q42, said endflframes being secured in this:

manner to prevent the b'oltsfrom interfering with the operators hands-when engaged with the ends of the ejecting-bar forthe purposeof, ejecting the finished blocksfrom the mold aswill behereinafter more fully I 7 described.

Fig. 11, are placed together a hollow drain tile is formed. It will thus be seen that a number of different sizes, shapes and designs ofbleclrs may be readily produced with my i .iproved mold.

Informing blocks with my improved mold the same is placed across the trough A; in which the concrete is mixed with the feet 3, of the mold, engaging the upper edges ,of the sides of the mixing trough as shown inl ig; l, of the drawings. When the mold is i"thusarrangcd, the facing plates 37, will rest 1 on the supporting bars 7, which are secured to the lugs 6, as hereinbefore described, said thus forniing the bottom of the hen the mold is in this position the wet concrete mixture s shoveled from .the

trough into the spaces between the partitions of the'niold'. When the mold has been filled in thiscnianner the concrete is packed down in the same, and scraped oil? smooth with the shovel. After being thus filled and scraped oil, the mold is inverted on asuitable surface the hands. This pressure on the bar forces the facingplates downwardly and inwardly and thus pushes tlieblocks out of the mold. When the ejecting barhas been brought down so close to thebails 5, as to preclude further pressure thereon, the bails are released and the handle bars l, are grasped by the fingers, thus permitting the thumbs and palms of th'ejhands to exert more pressure onthe ejecting bar to force the blocks entirely outof the mold. hen thebails 5,

are released they are prevented from falling inwardly by stop lugs 46, arranged on the inner sides of the feet 3, as shown. The upper faces of the blocks when thus formed Till be smooth or will have thereon a design according to whichever side of the facing plates 37 ,wasuppermost 1n the bottom of the mold. a

, From the foregoing description taken in 1 connection with accompanying drawings, the

constructionand operation of the invention will be readily iuiderstoodwithout requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to. without departing from'the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my said invention, whatI claim as new and desire to secure by .United States Letters Patent is:
