' of a mold designed for the constructionwgf concrete. Wells on he like, the mold be ng susceptible of adjustmente wells ious thicknesses, and also adjustable to provide for a quick release from said walls as the occasion requires.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure l is a side elevation of the mold structure.

The mold forming the subject matter of the present invention includes a plurality of mold sections which are arranged in spaced parallel relation, there being four of said sections used in a double wall construction. Each section is preferably constructed of metal, and may vary in size and configuration without departing from the spirit of the invention. The sections are used in pairs, and the respective sections of each pair are indicated at 10 and 11.. It will be noted upon inspection of Figures 2 and 3 that each section is also mounted on suitable supporting bars 12 which may be of any suitable design but preferabl of U-shape formation in cross section as wri in Figure 6. All of thcsebars depend from means designed to effect an adjustment between the sections otthe respective pairs of sections, both twee-angina; he secti ns e tive y, r Wall at d f erent th knes s s w as to provide fo i-a quiclg release of the moi structure irom the walls when desired.

h s adj i s ee waist o an ut-er pipeiliixth ends-of which are threaded to. a eeeimeile e als as how nF se-r s sa ad '17, while slidably arrangedwithin he pipe 13 is an inner pipe 15, the ends of which are also threaded to accommodate caps 16. Each of the caps 16 is provided with a threaded opening 17 which receive the threaded rod 18, the latter passing longitudinally through the inner pipe and journaled in the caps 14 closing the ends of the outer pipe 13. The rod 18 projects an appreciable distance beyond one end of the pipe 13 and is equipped with a hand wheel 19, through the instrumentality of which the rod 18 is rotated in either direction to effect an adjustment of the mold sections toward or away from each other as the occasion may require. In other words when the rod 18 is rotated in one direction, the inner pipe 15 is moved in one direction longitudinally of the outer pipe 1 for the purpose of moving the corresponding mold sections 11 away from the corresponding mold sections 10, and when the rod 18 is rotated in the other direction, the inner pipe 15 is shifted to move the corresponding sections 11 of the mold toward the fixed section 10. It will be noted that the bars 12 which support the sections 10 terminate to provide sleeves 20 which surround the outer pipe 1? and are held fixed relatively to said pipe by fastening elements 21, while the corresponding upper extremities of the bars 12 which support the sections 11 are offset and fastened to the inner pipe 15 by bolts or the like 22. These ofl'set extremities 23 pass through slots 24 formed in the outer pipe 13, so that they can be secured to the inner pipe 15 and moved therewith in the manner above described. Any number of these adjustable structures may be employed depending of course upon the length of the mold sections, two of said structures being illustrated in Figure 2. It is manifest that the sections 11 can be adjusted with relation to the sections 10 for walls of different thicknesses and moved in a direction away from the sections 10 to allow the mold structure to be quick y separated from the "walls .when suelr separation is'desiredflVhile it is believed that from the---fore------ going description, the nature andadvan tages of the invention will be readily apparent, I desire to have it understood thati'I' do not limit myself to what is herein shown and described, and that such changes "ma be resorted to when desired as fall within the'sco e of what is claimed.

' \Vhat'I claim is:

lfiA mold of the character described com prising a plurality of'stationary and movable'inold sections alternately disposed in p ai'allel relation, spaced inner and outer pipes supporting the mold sections, means connecting the stationary mold sections with the outer pipe, means connecting the movable section with the inner pipe, and means for adjusting said inner pipe longitudinally the outer pipe and adjustable longitudinally thereon to vary the space between said sections, means for holding said sections fixed relatively 'to the outer pipe, said"outer pipe having longitudinal slots, inovable' mold sections connected With'jthe inner "pipethrough said slots and alternately disposed with respect to the first mentioned sections, and movable toward and ai'vay; from the latter incident to the adjustment of said inner bipe.

In testimony whereof'l aflix my signature."
