JOHN N. HELTZEL, v.orwAEEErroi=rro,'liss1e1von To THE HELTzEL sTEELEoEivi a IRON oo., or WARREN, oHIo. Y f i l CONCRETE-MOLD-FOEM s'rAY.

To aZZ whom it maylconcern;

Be itknown that I, JOHN N. HELTZEL, a citizen of the UnitedStates, residing at Warren, in the county e of Trumbull and State of Ohio, have invented a new and useful Concrete-Mold-Form Stay, of which the following is a specification.

This invention relates to molding apparatus and more particularly to portable and adjustable concrete form stays. l

Theprimary object of the invention ,is to providea means for adjustably and removably supporting the side walls of the concrete form/toA permit thesame to be used in connection with concrete structures requiring various heights.` p

A further object of the invention is to provide means carried by the stay forl restricting the movement thereof when the same is being driven into the ground `surface on which the mold is being set up.

Vith the foregoing and other objects in view which appear as the description proceeds, the invention resides in, the vcombination and arrangement of parts vand: in the details of construction` hereinafter ydescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without de )arting from the'spirit of the invention.

eferring to the drawings Figure'l illustrates a side elevational view of the stays and concrete form supported thereby, one end of the form being broken away.

Fig. 2 illustrates a sectional view taken on line 2--2 of Fig. 1, and

' Fig. 3 is a top plan view ofV astay with the adjustable bracket positioned thereon.

Referring to the drawings in detail, reference character 5 designates a stay including right angle flange members 6 and 7, the lower ends of said flange members 6 and 7 being tapered to form the pointed end 8, to facilitate the driving of the stay into the ground surface on which the mold is to be assembled.

Disposed directly above the pointed end 8 of the stay is a brake, in form of a right Vangled-plate, including Vflanges 9 and 10,

the flange 9 thereof being secured to the VVflange 6 by means of rivets 11 passing through suitable openings 'provided in the flanges 6 and 9. l

Specification of Letters Patent. Patented J une 29, 1920. A Application ined octo'ter 4, 1919. serian No. 323,469.

As shown, the flange 10 extends at lright angles with relation to the flange 9, and is relatively'wide to engage the ground Vsurface when the stay is driven into the ground, to prevent orl restrict the movement of the stay into the ground, to vprevent the stay from being driven' too far, and to insure a relative height ofthe various stays used inthe mold construction.

. The flange 6, which when positioned forms the rear flange of the stay, has its rear ledge provided with notches as shown at 12,`the distance between the notches varying to provide various heights and adjustments for the bracket 13 to be more fully described.

4 Employed with each of the stays, is a rekmovable bracket-member 13 which is curved downwardly as at 14, ythe lower extremity thereof terminating in an 'upwardly extending hook member 15, to receive the downwardly extending flange 16 of theconcrete form 17. Y

VAs vs'hownby, Fig. 3 of the drawing, the bracket member 13 is provided with a'substantially L-shaped notch or slot 18, the por-` tion 19 thereof being widerthan the width of the flange 7 over which the same operates, to permit the bracket, when positioned on the stay,to fall down into a position to vclosely engage the flange 7 of the stay, and

at the same time permit the bracket to be moved upwardly in order that the bracket may be moved from the notch in which the same is engaging, to another position of ad- 4 justment.

The concrete form 17, forming a part of the invention includes a body port1on-18,which when in position lies at right angles with relation to the flange 7 of the stay, the upper end 19 thereof extending at right angles to the body portion 18', the extreme edge of said right angle portion 19 extending at right angles thereto and lies in a position to engage within the hook member 15 of the bracket 13.

The lower extremity ofl the body 18 also extends at right angles as at 20, and has its extreme edge extending upwardly as at 21 to closely engage the flange 7 of the stay in order that the same will be held in its horizontal position, against displacement.

In operation, the stays 5 are positioned in the ground surface until the brakes, secured thereto engage the ground surface to 2 F u u 1,345,179.

prevent the stays from being positioned too far into .theground surface, and to insure uniformity in the heights of thestays;

The bracket members 13 arenow positioned in the proper notchesof 'the stays,"

crete mold, but it is of course obvious that two of such structures are positioned in spaced relation with each other to `form the opposite sides of the mold, to permit the plastic concrete to be positioned therebetween. u

Having thus described my invention,what I claim is Y y 1.v In a portable"mold, stays including angle irons, one of the walls of each of said stays having notches, a bracket member positioned on each of the stays, said bracket member having a substantially L-shaped slot formed therein, and Vadapted to embrace the stay, one of thel walls of said L-shapedslot coperati'ngfwththe notchedV walls of the stay for holding the bracket in various positions of adjustment, and means on one end of said bracket for securing a concrete form thereto.- Y Y u 2. `In 'a portable mold, stays, each of said vrestrictin'gf .'novement thereof u ground surface on which the mold is supstays being provided with a notched portion,

bracket, and means carried by the stay for into lthe ported. Y Y

3. In a portable mold, stays, each of said 'stays vhaving a plurality of notches formed along one of the edges thereof, a bracket having a slot embracing the stay, one of thev a bracket supported on each oft'hese stays, a ,concrete form removably supported by the walls of said slot cooperating' with Vthe notches and eans carried bythe stay for restricting -movement thereof y,into the groundsurface,` on which thelmold is supported. 'f f 4. In a portable mj'old, stays, each off said stays being provided withja notched portion, a vbracket supportedy by* each 'ofthe stays, eachv of said "stays having a slotted portion embracing the bracket, -one of the walls of said slotted Vportion l'coperatingwith the' notches lfor supporting the bracket in various Vpositions of adjustment, Vand said bracket being curved downwardly to setup i a binding actionl between theV bracket vand stay, and amovab'le form 'supported by the bracket. i 1

Y In testimony 'that Icl'aini the foregoing as my own, I have hereto aixed mysignature in the vpresence 'of two witnesses.V A
