Patented Mar'. li, l'il To all whom 'it may concern.'

lle it known that l, .lonx S. Ln'ron, a citizen ot' the UnitedL States, and a resident of Anderson, in the county of Madison and tate of Indiana, have invented a new and improved Raising Device for Molds, of which the following'is a full., clear, and e2;- :ict description.

My invention relates to a raising device for molds employed for making concrete walls or the like having reinforcing 'oars therein, and has for its object to provide device tor building a reinforced wail concrete or the like, the 4mold thereof being adapten to be raised from ausl over the concrete wall after the same has sntiiciently set, and constituting the torni for a second section of the saine wall, and so on upwardly until the said wall is completed to the tlcsirecl height.

An embodiment or my invention comprises a tranne secured to a niolcl for concrete Walls or the like having reinforcing bars therein, :L workingplattform secured to the said trame, and means for raising the said mold to a desired height over a finished Woll, previously formed by the said molti, preparetory to molding another portion ot' the said wall over the same and forming a part thereof, with tno seid mold, which is raised after erich succeeding Wall portion has snnlciently set, until the desired height of the said wall formed by the combined mold portions molded one wall7 is reached.

lviy invention still further embodies certain novel features of construction, as will be hereinafter more fully described and par ticularly set orth in the appended claim. Reference is to be had to the accompanying drawings, forming a part of this specitication', in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 'l shows a plan view oi' my invention as applied; Fig. Q is a sectional side elevation or' the saine; Fig is an enlarged detail sectional view, parte being broken awa showing the mea-ns for raising the mol 5 Fig. 4 is a sectional plan View taken on the line i-l in Fig. 3; Fig. 5 is a plan View of the jack head; F ig. 6 1s a plan view of the clutch showing the removable cover thereof; Fig. 7 is a View of the same with Athe cover removed; and F ig. 8 is a sectional View taken on the line 8--8 in F ig. 3, showing the concave clutch ,members with afreiniorcing bar therebetween.

A inolcl l0 isprovided, comprising sides ll, and secured thereto by means ot braces l2 and. fastening members 13, is e iranie- 'vvork 14. The framework le comprises ver tical members l5 and suitable tliagorml` braces 16, and secured to the saicl 1 C worlr l-l is e working platform 17, heli. horizontal position on the framework ltby a brace 1S. A cross plate 19 is rcvirlei, l

secured to the framework fl, an" seen to 'the said framework by suitable bolts, l a jack heeel 20. A hollow raising screw 2' is slipped over a reinforcing bar 22 need 'for strengthening the wall, and secured to the screw 2l 'is a ratchet 23 engaged. by n reversible pavvl 24, the' whole constituting a lifting jack 25, having a handle thereon for operating the saine. A. locking clutch 27 is (provided, tnrnably helcl on the screw,

Q1 an having therein oilset concave toothed wheels 28, adapted to engage the reinforcing bar 22 'and securely grip the same to prevent the mold and framework from slipping downward thereon. Springs 29 are secured to the sioles of the clutch 27 end. help-thc wheels 28 'to grip the reinforcing bar. 22, and a removable cover 30 comprising similar pertsl is bolted to the clutch 27. The wheels 28 are preferably concave to enable the saine to more easily grip the reinforcing bar The raising.,` jack 25 is equipped with a spring 32 engaging the pawl 24 fior holding the saine Ain engagement with the ratchet 23, as Will be easily seen by referring to Fig. 3.

The operation ot` my device is as iollows: The reinforcing bar 22 is placed in the mold 1l, and the raising jack 25 and parts thereot are arranged as shown in Fig. 2. Concrete is then ooured into the mold anti allowed to harden. l/Vlien the concrete `has suificiently set, the jack 25 is operated and forces the mold to move upwardly, the head 20 `yeing secured to the framework 15 of the mold 1l and being screw-threaded therein for engagement with the ,raising screw 21. When the, mold has been raised to such a height that the lower part of the mold still covers the 'ripper part or" the linished Wall, the precise o eration as heretotore described is repeater ,and in this way an entire well can. be easily formed with one mold, the said Wall when finished having the appeamnce of. one complete wall. The locking clutch 27 pi'evens any down.- wad 'movement and the Wheels Q8 seeiu'ely grip 'die i'einfeieing bei" `Wlien the Well is completed the reinfo'feiiig bei is eut eli? at the top, the mold and raising device be ing ready te be used te eenetmei; :mother Well.

It will be undelsood that any number of raising jacks can be used en one mold, depending only on the length of the Wall. It will be Still further understood het the misinijaek 25 is reversible and should the jack lieud 20 and the lockin clutch 27 come within close proximity et each other, the Said jack 25 can be operated te separate them by ineens of the reversible Spring-actu ated pawl 24 en 'the jack 25.

Having thus described my invention, I claim as new and desire to secure by Letters latent:
