CONCRETE-WALL MOLD.

T0 all whom t may concern Be it known that I, JESSE W. ALEXANDER,

a citizen of the United States, residing atV are z-(a) The production of form .molds of simple. and inexpensive construction; (la) the provision of means whereby the plates of which the moldsl are chiefly formed may be brought into operative positions quickly, accurately and with the minimum exertion of manual effort; (c) a strong and durable construction both in the matter of lthe individual members and in the manner of their assemblage into the complete apparatus.

Having the foregoing special objects,

`- and others of general utility and novelty in view, I have invented the apparatus of which a preferred adaptation is illustrated in the accompanying drawing, in which z` Figure 1 is an elevational view of a set of frames and complementary parts,which constitute a single unit-of my invention, vthe same being shown in connection with a section ofv hollow or spaced concrete walls;V

Fig, 2 is a sectional and plan detail on the line 2-2 of Fig. 1; Fig. 3 is a detail plan view of the plate operating lever. and adjacent parts, and-Fig. 4 isy a view partly in section and partly in plan, onl the line 44 ofmFig. 1.

'In carrying out my invention, I prefer` ably employ a plurality of vertical stand-- ards, which may be I-beams, channel or L- bars, or other suitable forms, and these are spaced apart siX or eight feet and supported or secured at their ends in any approved manner. I have shown in the accompanying drawings, a special form of I-beam, designated by the reference numeral 3, as peculiarly adapted to the members which make up complete apparatus. These beams are erected on opposite sides of the wall under construction, at the proper distance from the structure to accommodate the moldplates and their complementary members.

Application 1ec1Apri12'7, 1914. Serial No. 834,560.

4-4 represent flat metal bars which are arranged in pairs and spaced apart to receive between them the beams 3, with which they stand parallel. Each bar 4 has mounted near its ends, grooved wheels 5, 5, which are adapted to ride on the adjacent flanges of the I-beams. Nearv their upper ends, the four bars 4 which make up a frame unit are rigidly connected by a horizontal bar 6. Eachpair of bars 4, has bolted thereto horizontally arranged angle-bars 7 8, which hold the bars in true parallel relation.

9 represents one ofthe mold platesemployed in my apparatus. This is made of sheet metal in any size desired, at its upper edge is flanged over as at 9a, and along its lower edge is provided with an angle-plate 9b, which serves tostiffen lthe plate, and properly connect it with the members by which itis supported.

10, 10a, represent respectively the horizontal and vertical portions of an angular frame preferably formed of channel-iron. T-bars 10b are bolted at the upper corners of the frame 10, and are engaged by the flange 9a to support thefplate 9, in vertical position, the angleeplate 9b, resting against the lower corner of the frame' 10.

11 represents a hinge-rod, portions of which are squared, as at 11a, 11b. The ends of this rod are journaled in socket-plates 12 which are bolted to one of the bars 4. On the squared portion 11b is mounted a handle 13 by which the rod is turned in its sockets. On the squared portions 11a, are mounted horizontally4 extending arms 14, with which are pivotally connected one end of links 15, the other ends of which are pivotally connected with brackets 16 on the frame .member 10a, thus forming a double hinge connection between the rod 11 and --lVhile I have shown the various parts that make the complete structure, at the left hand side of the drawing only, it will be understood that the parts designated 7 to 16, respectively are duplicated, and taken together provide the forms for the outer face of the walls under construction.

17, 18, represent respectively, the coreplates of my improved apparatus, the same lcorresponding in size and material withA the plates 9. Thecore-plates are cut and bent over at their upper edges to'provide hangers which embrace bolts 19, 20, which-are slidably arranged in slots 6*?, in the bar 6,

and in a brace 6", which is bolted to the bar 6 (Fig. 3).

Angle- bars 21, 22, 27 and'28, are bolted to the opposed sides of the plates 17, 18.. A rod. 23 is journaled in the bars'21, 22, and has la lever 24 on its upper end. Portions of the rod 28, are squared and arranged on such portions, are links 25, 26, thev free ends of' which are slidably and pivotally connected with 'slots 27, (Fig: 4) in the barss27, 28. In Fig. 4, I have shown the' positions off the@rv link 25 whenv the core-plates arefinl theirexfy panded position, and inFi'g. 3, Iaha've showni the lever 24 in the positionitA assumes" when the plates are'retracted, but the latter.k areshown in their expanded relation.

29 represents gravity levers or dogs A:whicha are pivoted on the bars 4, in. positionfso thatthe pointed end of'thedog will eI-igai-ge; the web of bar 3, and. thus support the.` apparatus in whatever: position it may havey been raised to," As many of these dogs will be provided as may be necessary yfor the sup'- port of each unit. I

In the use of my improved-apparatus, suitable beams 3`will be erected in a. man'- Vner appropriate to prov-ide vertical standards of vsuiicient rigidity andi height. to

' scribed, will be arranged' at the base of the beams 3, and the outerfface inoldlplates 9',

will. be Vmoved'to the desired relative posit-ion by .operating the leversl. rllhe core-plates 17-1'8, will thenbe expanded to the extent required to make concrete. walls. of the def sired thickness',l and. Ythe concreteV will. be poured between the mold.` Walls composed of plates 9 on the outer tace andplat'es 117-18* respectively onk the inner face.. :When the: concrete has set suflioiently to permit the re"-V moval of the plates, the apparatus-will be raised by any suitable means, andV will be' held in such position bythe' ddgs 29 as above set forth. f'

It is obvious that I mayy duplicate the-ar-A rangement and connections ofI the operating. rods 11, 23, so that: they willsupp'ort. .the

plates 9', 17, 18, at as many points as the character of the work may require.

It' is also obvious that the construction disclosedprovidesfor the proper alinement of the plates and their maintenance, to effect a wall of true dimensionswithout the. use of"ties,vwhil'e facilitating the'quick and easy adjustment.- of th-"eplates in planes at right angles to the face of the walls under construction.
