Beit known that I, DANIEL M. EDDY, a

citizen of the United States, residing at in Fig.

' throu h the mol Topeka, in the county of Shawnee and State of Kansas, Building-Mold, of which thefollowing is a specification.

This invention relates to molding machines of that type particularly designed for use in the construction of concrete walls.

The object of the invention is to provide a machine desi ed to be set up to travel along. the line 0 the wall or walls-to be constructed, said machine carrying a mold oi novel form which can be qulckly set up and shifted from place to place.

A further object is to provide a moldin machine capable of producing walls of di ferent heights, said walls being provided withcontinuous openings extending vertically therein. I

Another object is to provide a molding machine capable of being easil manipu' lated and which, after being) p aced at a predetermined elevation, can e u orming a plurality of tiers or layers of molded wall.

With these and other objects in view, the

I invention consists of certain novel details of construction and combination of parts hereinafter more fully described and pointed out in. the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :--Figure 1 is a perspective view of the machine, the same being shown in use; Fig. 2 is a vertical longitudinal section through the mold and through the molded block therein, the cores being shown in. elevation and withdrawn from the mold. Fig. 3 is a central vertical transverse section through the parts shown 2, the-front panel of-the mold being shown loosened and out of contact with the molded block. Fi 4 is a horizontal section and the adjoining portion 0- the tower, the parts being in the positions shown in Fig. 3'. a

Referring to the figures. by characters of reference, A designates a portable tower preferably consisting of corner posts 1 conneeted attheir upper and lower ends and at intermediate points by horizontal beams 2 constituting platform supports. This tower is mounted at its lower end u on wheels 3 designed to travel upon a trac B have invented a new and useful.

tilized for referably made up of sections which can e conveniently placed together in any desired relation, so as to permit the tower to travel along lines parallel with the walls being built. The mold C used in connection with the tower consists of a back panel 4 referably formed of sheet metal and havmg flanges 5 extending at right angles from the ends thereof and in the direction of the tower. Secured to this back panel and near the flanges 5 are reinforcing strips 6 preferabl formed of angle iron, and to which are rigidly connected the fixed end "plates7 of the mold. These end plates extend at ri ht angles to the back'panel 4 and roject orwardly therefrom, said end p ates being located entirely above the back. panel, as clearly indicated in the drawings. suitable means, such as hooks 8, are secured to the end plates 7 for engagement with hoisting cables 9. These cables extend up- 'wardly over sheaves 10 carried by the.t op

ortion of the tower, there being arms or rackets 11 upon the outer side of the top portion of the tower on which these sheaves are journaled, so as to be in substantial vertical alinement with the hooks 8. Additional sheaves 12 are mounted upon the top of the tower adjacent the inner side thereof and the cables 9 extend thereover and down-- wardly to a shaft 13 journaled on the lower portion of the tower and designed to be rotated 'in any suitable manner, so as to wind the cables simultaneously thereon, and thus elevate the plates 7 and the parts connected to them;

Any.

' Hangers 14, preferably formed of angle iron, are pivotally connected at their upper ends to the u per portions of the end plates 7 adjacent t e front edges of said plates, as indicated at 15. The hangers 14 are of the same length as the reinforcing strips 6 and secured to the lower portions of these hangers is a front panel 16 of the mold, said panel being of the same proportions and size as the rear panel 4 and provided at its ends with outwardly extending flanges 17. Reinforcing strips 18 are preferably arranged along the top and'bottom edgesof the panel and also along the center thereof, and, if preferred, a similar arrangement of reinforcing devices may be provided on the back panel 4. Locking levers 19 are 'pivotally connected to the lower portions of the end plates 7 and are provided with camcxtensions'20 designed to swing downwardly into engagement with the upper reinforcing strips 18 of the top panel, andthus hold said panel as Well as the hangers 14 against swinging movement relative to the end plates 7 and the back panel 4.

. The mold is designed to be closed at. its ends by meansof removable end anels 21, v

- each of which is provided at its ack edge with an inturned ange 22 designed to hook into enga ement with oneof the flanges 5 of the 'bac panel 4. The front edges of the end anels are designed to rest against the end anges' 17 of the front anel16 and suitable means may be provi ed for fastening these front edge ortions of the end panels to the flanges 1 In. the drawings, the

levers 23 have been shown pivot-ally mounted upon the end panels 21 and'each having a hook or clip 24 designed, when the lever is swung in one direction, to embrace the meeting edges ofv the panel and flange .for the purpose of bindin the two together, and thus preventing acci ental displacement.

- The end plates 7 are connected adjacent their lower ends by means of'a guide plate 25 arranged perpendicular to the said end plates and to the strips 6, said guide late having a series of alinlng openings 26; t erein for the reception of the cores 27 of the Openings mold. These cores are preferably tubular.

and slightly tapered toward their lower ends I and they are designed. to I slide within the openings 26. The upper portions of the cores are mounted within openin 28 formed within a head 29 which norma ly rests at its ends on brackets 30 extending inwardly from the end plates 7. Supporting pins 31 extend transversely through the 'co'resan'd rest on-the-head, thus prevent-ing downward movement of the cores relative tothe head,

but permitting them to rotate therein. 32 are formed within the cores close to the guide 25 and these 0 enings are.

designed to receive pins 33 where ythe cores can be conveniently rotated forfthe purpose:

of lodsening them prior to the withdrawal thereof from the mold. Cables 34 are con nected to the end portions of the head 29 and extend upwardly over sheaves 35 carried by the brackets 11. These cables also extend rearwardly over additional sheaves 36 upon? the tower and thence downwardly to the shaft 37 designed to be rotated in any-pre-' ferred manner, as by means of a crank 38,." so as to simultaneously wind the cables, and" thus withdraw the cores from the mold.

As indicated in the drawings, the panels" 4 and 16 extend some distance beyond one.

of the end plates 7,510 that they will lap the molded portion of the wall while an additional section is being formed.

If desired, means may be employed for I preventing the mold from shifting laterally with relation to the tower, said means in the present instance being shown as formed of a hooked arm 39 pivotally connected tolone of the hangers 14 and designed to swing into engagement with one of the corner posts 1.

In using the machine herein described, the track B is first arranged alon lines parallel with the lines of the walls to e constructed, said track being located at a predetermined distance from, the 'walllines, so that when the mold is properly connected to thetower A, it will be incorrect position above the foundation of. the wall. The cables 9 are paid out, so as to lower-the panel 4"on to placement of the mold during the filling o eration. After the concrete has proper y set, the cores 27 are separately rotated'by placing the .pins 33 in o enings 32. The cores are thus loosened rom the concrete and by winding thetcables 34, the head 29' can be elevated and thus withdraw the cores from the mold. The end panels 21 are then disengaged from the front and rear panels and removed, after which the front panel is swung outwardly from contact with the moldedblock. While the parts are in this position, the tower Acan be drawn along track: B and the advancing outer post 1 thereofwill push against the adjoining strip 6 and cause the panel 4 and the restof the mold to travel with the tower, and said mold willthus be withdrawn from the block previously formed. thereby. The mold ismoved into. position with the extended ends ofpanels' 4 and16 lapping the block previously molded, and the panel '16is then swunginto closed position "and secured 'in place by means of the levers 19. Only oneend panel 21'is. utilized after thefirst block in a tier or layer'has. been formed, this panel being placed at thatend of the mold' farthest remove"d from the block previously formed. After-the mold has again been, set up in this manner, the cores are inserted thereinto, and

the foregoing o eration will then be repeated. After b ocks have been molded in this way throughout the-length'of all the walls, the mold can be bodily elevated, so as to permit a second tier or layer of blocks to be molded in the same manner, asfheretofore described. It is of course to be understood that any desired number of layers or tiers of blocks can be formed without necessitating .the elevation of the tracks and tower, this. number only being limited to the'heightof the tower. the upper tiers are being molded it is designed to six- 1S-.-

tend the lower ends of the cores short tances into the openings formed in the next adjoining tier thereunder, so that after the wall has been completed, continuous air ing a concrete wall is greatly reduced, and,

the cost of construction correspondingly diminished.

It is of course to be understood that various changes may be made in the construc-.

tion and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.
