CONCRETE FORM SUPPORT Filed Sept. 8, 1950 2 Sheets-Sheet 2 ATTORNEY Patented Feb. 9, 1932- UNHTE TE'ES 1,844,7tiil' enonen r-rAYNns, or "INnrANaPonIs, iNDIANA CONCRETE 3303M SUPIfORT Application filed September 8, 1930. Serial N0. 480,57O.

his invention relates to a support for concrete forms, the general object of the invention being to provide an adjustable support for holding a beam in vertical position so that the beam will support a part of the form, the supporting means consisting of a pair of uprights for receiving the beam between them and an adjustable seat carried by the uprights for the lower end of the beam, with clutch means for holding the seat in adjusted position.

This invention also consists in certain other features of construction and int-he combination and arrangement or" the several parts,

to be hereinafter fully described, illustrated in the accompanyingdrawings and specn'i cally pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sew erul views, and in which 2- Figure 1 is an elevation of the invention,

showing the same in use.

Figure 2 is anedge view thereof.

Figure 3 is a section on line 3-3 of Figure 1. 1

Figure a is a section on line 4 l of Figure 1.

Figure 5 is an enlarged sectional view showing the clutch means for holding the 1 ed together by a member a w seat member in adjusted position.

Figure 6 is a section on line 66 of Figure 5.

Figure 7 is a view of one of the clutch members.

Figure 8 view showing how the device can be extended. when necessary.

lin these drawings the numeral 1 indicates a pair of pipes having their lower ends screwed in the sockets :2 of a base piece 3. The upper ends oi the uprights are connectch has holes 5 therein for receiving the pipes and the member is fastened to the pipes by the set screws 6. This member has an opening 7 therein through which a beam 8 is adapted to pass.

A casting 9 isformed with the holes 10 through which the pipes pass and with a cenbe held in adjusted tml Opening. 11 its upper Part in which the lower end of the beam fits. The casting is also formed with the longitudinal passage 12 which extends through the ends of the casting and intersects theholes 10 and ther-" opening. The upper walls of this passage slope upwardly at the ends of the passage, 1 as shown at 12, so that the ends of the passage are enlarged. A plate 13 is'arranged in g each enlargement of the passage, each platetfio having a depending flange 14: at its outer end i which extends beyond the end of the casting.

A. pair of springs 15 tends tohold each plate againstthesloping top wall 12 and each plate has a hole 16 therein through which a? pipel passes. Thus the springs 15 act to hold the plates 13 in tilted position so that the walls of the holes 16 will grip the pipes and hold the casting in adjusted position onthe pipes. By lowering the outer ends of theE- plates 13, the walls of the holes 16 will be moved out of gripping relation with the pipes so that the casting can be adjusted on the pipes. Thus these plates and their springs form clutch means for fastening the casting to the pipes so that the casting will position and will support the beam. l i i v i plunger 17 passes through a hole in the bottom oft-he casting and extends into the passage and is held in position by a pin 18. The beam 8 contacts the upperend' of the plunger so that bypushing upwardly this plunger the beam will be raised to relieve the plates 13 from itsweight, so that the plates can be lowered to permit adjustment of the casting.

When desired, the device can be lengthsued by placing the pipes 21 on the upper ends of the pipes 1 and passing the rods 22 through said pipes 21 into the pipes 1 and when this is done, the member 4.- should be raised to theupper ends of the pipes 21. Thus it will be seen that the beam 8 can be adjusted in the supporting means so that its upper end. will properly support a part of the form,

as shown in Figures 1 and 2. This device may receive any length of beam and the seat for the beam has a double grip on the standards or pipes. One of the great advantages of the device is the ease with which the length of shore can be increased either by changing the lengths of the pipes or adding to the length by using the extension pipes. An-

5 other important feature of this shore is its durability, as there is nothing breakable about it and :should the pipe standards bend, theymaybe easily straightened or replaced on the ob. The parts are of light weight so that they can be shipped and handled very easily and the device can be easily repaired on the job.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may 'be'madein theconstruction-and in the combination and arrangement (of the'several parts, provided that ESllCll changes fall within the scope of the appended claims.

What claim is 1. A device ofthe class described comprising alpair ofuprights, a castinghaving'holes therein through which the uprights pass, said Roasting having openings ,in its end vportions, aplate arranged in each opening and having a hole therein ='through which the upright passes, means for holding the plates in tilted position whereby portions ofithe walls of the 30 openings therein willengage-the uprights and :thus look the casting in adjusted position -.on the uprights :anda beam having its lower :end supported by the-casting.

:2. A device of the class :described com- 16 prising a ;pair-;o.f uprights, acasting having holes therein through which the uprights pass, said casting having openings inits end portions, a plate arranged in each opening :and having-a @hole therein through which the '40 upright passes, means for holding the plates in tilted position whereby portions of the walls'oi the openings'therein will engage the uprights and thus lock the casting inzadiusted position-on the auprights, :a beam having its lower end supported by the castingand restsing on the inner ends of the plates and a plunger carried by :the 'lower part of the eastingfor raising the'beam when the plungeris-pushed upwardly'for relieving the plates -:o.f=the weightofthebeam.
