Be it known that 1, 1101' N. NEIL, a citiI- en ol' the boiled States, and a resident; of tozad, in the county of Dawson and State. of Xehraslca, have invented a new and improved (oncrcie-Mold, of which the l'olloaing is a full, clear, and exact description.
My invention relates to concrete molds. and it has for its object to provide one with side members which are connected by spools supported by rods disposed therein, the spools having hollow heads in which the rods are screwed, there being also additional screw threads in receswes in the. extremities of the heads in which nuts having orilices therein are adapted to mesh, there being means in the heads respectively to prevent the rotation of the heads on bolts which are disposed in the orifices in the nuts respcctively. I also provide hollow cores to be disposed between the side members and the spools, the hollow cores and the spools being permitted to remain in the concrete alter the bolts are withdrawn and the side members are removed, but if desired the spools maybe Withdrawn it this is done at the proper time, the heads being first unscrewed.
Still other objects of the invention will appear in the following complete description.
In this specification I will describe the pre ferred form of my invention, but it will be understood that I do not limit myselt' thereto as I consider myself entitled to all'l'orms and embodiments of the invention which may pended claims.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, in which Figure 1 is a perspective View showing my mold erected ready for concrete to be distransverse sectional view of my invention; Fig. 3 is a plan View of my invention; Fig. 4 is a similar plan View but with hollow cores of a different shape disposed in the concrete; Fig. 5 is anenlarged fragmentary View show ing a spool, its head and the bolt by means of I which 1t is hold to aside member; Fig. 6 is a similar view but showing caps by which the spool heads are separated from the side memher, and Fig. 7 is a similar view showing the spool with its head embedded in the con- Specification of Letters Patent.

moved and a bolt and nut disposed in an oiilicc in the head ol' the spool, the out being screwed into the spool head and the head of the bolt being disposed in an angular recess i the head.
By referring to the drawings, it will be seen that side members] are provided, which may be constructed olJmctal or other nmterial. though in the drawings the side members are shown as constructed of metal with angle steel portions 2. at their edges, the'angle steel portions being bolted to the side members to still'en them. Between the side members 1, which are. spaced apart, are disposed spools 3, having heads 4, bolts 5 being disposed through the spools and heads, the bolts passing through ori'lices 6 in the side members 1 and through orilices 7 in angle. steels 8, which are bolted to the side members 1. 'lhc bolts 5 are held in position by means ol nuts 9, which mesh with screw threads on the bolts and press :Wainst the angle steels S. The spools 3 are scrmved into theirheads 4, the heads raving threaded recesses l0 and angular recesses 11 disposed inwardly from the threaded recesses 10. This construction isprovided, so that when the nuts 9 are removed and the bolts 5 are with drawn from the spools 3, a nut 11.? having an oriiice 13, may be screwed into the recess 10 in the heads 4, and a bolt 1 1-. disposed in the oriiice 13, the head 15 of the bolt 14 being disposed in the angular recess 11, to prevent the bolt 14 from rotating. By this construction, it is possible to secure the concrete mold to other members, or to supports which will hold the concrete mold in a predetermined position. It is also possible to unscrew the heads 4 and remove the spools It;
provided this is done before theconcrctc has become too hard. When it is desired to have a smooth surface of the concrete block, unbroken by the spool heads 4, caps is may be, disposed between the spool heads 1- and the side member 1, so that when the nuts l) are removed and the bolts 5 arc witlnlrawn, the caps 16 may also be removed and the spool heads 4 may be covered by concrete mortar. Between the side members 1 are disposed hollow core members 17, which may be annnlar in shape in cross section, as shown in Fig. 3, or elliptical in shape, in cross section, as shown in Fig. t. when elliptical hollow cores 18 are used,1 prel'cr tolap them as shown in Fig. 4, to all'ord additional strength, and additional resistance to the passage of heat and moisture, the cores 18 being spaced apart at intervals to permit the spools 8 to be disposed therebetween. The angle steels 2 have orifices 19 therein, in which may be disposed studs, the studs projecting into similar orifices 19 in an adjoining side member which is disposed in alinement or at an angle with the first named side member, and which it is desired to retain in this position. Guides 20 project from the side members 1 near their top and bottom, the object of these guides 20 being to enable the side members to be read justed after a mold has been formed, so that the lower guides 20 may be disposed in the recesses formed by the upper guides 20, and in this manner a concrete wall may be formed by degrees with the side members disposed in the same plane, after they have been advanced to the new position. Angle steels 21 are bolted to the inner faces of the side members 1, the angle steels 21 being pro vided to support a smoothing member 22. which is provided for smoothing the top of the concerete block or wall at any predetermined height, the angle steels 21 being ad- 'ustable on the sidemembers 1, as they are bolted to the side members 1 and to the angle steels 8, the bolts passing through orifices In using my invention, the side members 1 are erected with the s ools 3 disposed therebetween and with the olts 5 disposed in the spools. The nuts 9 screw on the bolts to secure them firmly to the side members 1 and to the angle steels 8. The angle steels 21 are then adjusted at the )roper height, and are then bolted to the side members and to the angle steels 8. Hollow cores of the desired shape are then disposed between the side members 1, when the space between the side members 1, with the exception 01' the openings in the cores, is filled with concrete tothe level of the angle steels 21, when the smoothing member 22 isdisposed on the angle steels and the upper surfaces of the mold is leveled. After the mold is sulliciently hard the nuts 9 are unscrewed and the side members 1 are removed, and the bolts 5 are withdrawn, leaving the spools 3 with their heads and the cores in the mold but if desired the heads be unscrewed and the spools may be withdrawn. The bolt 14 is then disposed in the orifice 13 in the nut 12, the head 15 of the bolt bein inserted in the angular recess 11 in the spool head 4 and the nut 12 being screwed in the threaded recess 10, the concrete block being adapted to be supported by the bolts 14. When there is no necessity of using the bolts 14 to support the *oncrete bloc r, the caps 16 are provided to separate the head 15 from the side member 1, and after the side member 1, the cap 16 and the bolt 5 have been removed, the spool'head 4 is covered with concrete mortar to make an even surface on the side of the concrete block. As has been stated, when a wall of any ,height is to be constructed, after the side members have been removed from the concrete wall already formed, they are disposed so that their lower guides will rest in the recesses previously occupied by the upper 1 guides 20 on the side members, so that the same side members which are used to construct the lower portion of the wall may be used to complete its upper construction.
