JOEE? N. HELTEEL AND FRANCIS 0. HEL'IZEL, OF WARREN, OHIO.

CONCRETE-FORM.

To all whom it may concern Be it known that we, JoH rN. HnL'rznL and FRANCIS O.'HELTZEL, citizens of the United States, residing at Warren, in the county of Trumbull, State of Ohio, have invented a new and useful Concrete-Form, of which the following is a speclficatlon.

This invention relates to improvements in provide a --connecting member which will permit the removal and replacing of the side rail without disturbing the connectlng members.

A further object of the invention is to provide a pedestal of the class set forth, having a stake adapted to be driven into the ground and which stake is located at some distance from the side rail, whereby the stake may be removed without danger of in'uring the side rail.

ith the foregoing and other ob ects in view, which will appear as the description proceeds, the invention consists in the novel features of construction and combination of partswhich will be more fully described hereinafter and particularly pointed out in the claims.

In the drawings accompanying and forming part of this specification,

Figure 1 is a perspective v1ew of a side rail of'a concrete form, showing three of our improved pedestals in position for holdin the same;

Tig. 2 is a side view, on an enlarged scale, showing the pedestal in rail-engaging position, therail eing broken away at its ends;

Fig. 3 is a cross section taken on the line 3-3 of Fig. 2, looking in the direction of the arrows; and

Fig. t is a cross section of the pedestal, taken on the line 4-4 of Fig.3.

The same characters of reference designate the same parts in the different figures of the drawings.

Side rails adapted to be used in concrete construction for supporting the bulk of the concrete, as heretofore constructed, are provided with sleeves or other means at their ends for the purpose of connecting two rails Specification of Letters Patent.

together. Such sleeves are usually riveted or welded on the ends of the rails, and it has been found that they frequently get knocked off in the handling of the side rails. and, as hereinbefore stated, the primary ob ect of the present invention is to do away with the use of such sleeves.

Referring to the drawings, 2 designates.

a side rail, which is bent into approximately C-shape form in cross section, as best shown in F 1g. 3, one side of the rail being wider than the other, the wider side forming the upper side when the rail is in use and on which the strike off or finishing machine is operated.

For supporting the side rails in upright position without the necessity of riveting sleeves to said side rails in order to connect them together, we have provided a pedestal or base member comprising in the present instance a base plate 3 having at one end thereof a downwardly extending flange 4 that is preferably pointed .at the center of its lower edge thereby to facilitgte its being driven into the ground. The ase plate is provided with an opening immediately back of the flange 4'. through which passes a steel stake The stake is preferably rectangular in cross section so as to effectively resist twisting strains thereon. The stake is provided with a bent over head 6 at its upper end which serves to prevent removal of the stake from the plate in one direction and also aifords a convenient means for withdrawing the stake from the ground when it isdesired to remove the forms. The stake is pointed at its lowerend to facilitate its being driven into the ground, and after insertion into the opening of the base plate the stake is spread or flattened at its side edges at this end, as shown at 7 thereby to prevent its complete withdrawal in the opposite direction from the base plate.

Mounted on the base plate 3 is an up right member 8 having an L-shaped lower portion which is secured, preferably by rivets 9, to the base plate, the upper end of the member 8 being bent outwardly and downwardly, as shown at 10. to snugly fit within the upper end of the side rail 2. For stiffening the upright or sleeve member 8, the metal at the angle between the horizontal and vertical portions of the member is struck up approximately at the middle:

of the width of the member to form a rib or her 8 is riveted to the base plate approximately at the center of the length of the base plate, whereby a portion of the plate extends under the side rail and for a short distance under the concrete wall or road. The object of this extension is to afford additional stability to the pedestal, the concrete lying on the edge of the plate assisting in keeping the base plate from tilting over when excessive side pressure is put on the side rail.

lin the operation of the structure described may be lined up to line and grade and the side rails afterward hung in position, or the side rails maybe connected together by placing a pedestal at each joint, with the end cit one rail resting on halt of the upright member 8 and the end of the adjacent rail on the other halt of the upright member,

and afterward the side rails may be brought to line and grade with the pedestals in place and staked into a fixed position. if it is found thatthe sub-grade is too low, a suhicient' amount of earth or blocking is placed under the bottom or base plate and the pedestal elevated to the proper grade. lit a sandy or soft soil is encountered, base plates will be provided having sufficient area to carry the weight that might be placed on the side rails to prevent the side rails from Sinhing below the grade level. @n the other hand, it a rocky surface is encountered anywhere along the side rail, the supporting pedestal midway between the two ends of the rails may be moved along the side rail to any convenient point that is more suitable. Again, a condition may exist where it is necessary to place extra pedestals under the side rails after the latter have been placed in position, and even after the concrete has been put in place, and of course this can readidy be done with our improved pedestal. In the use of these structures it frequently happens that when the side rails are set in position it becomes necessary to remove some of the rails to permit teams or other vehicles to pass through. By the use of the pedestals herein described the side rails can be lifted out of position without removing the pedestals or supporting members, and the side rails replaced in their original position without resetting or re-lining the pedestals.

With the systems heretofore in use the stakes were placed adjacent to the side rails, and it was an impossibility to remove the stakes without injury to the concrete struc ture because of the necessity of striking the stakes to disengage them from the rails. In

the present improvement, however, the stake is located at a sufficient distance from the rail so that if it should be necessary to strike the stake there would be no danger of damaging the concrete. Inmost cases it will be unnecssary to strike the stake to disengage it, since it may readily be disengaged by inserting the'end of a pick under the the wheels of the, road machine pass over said joints.

While we have described in detail the structure herein illustrated, it is to be understood that we do not thereby limit our invention to the precise features of construe tion shown, as we are aware that many mechanical changes may be made therein without departing from the spirit and scope or.

the invention as set torth in the appended claims.

Having thus described our invention, what we claim is:

1. A structure of the class described, including a supporting pedestal having a base plate adapted to rest on the ground and provided with a projecting-stake adapted to be driven into the ground to hold said base plate in a fixed position, and a vertical miember projecting upwardly from said base ate.

p 2. A structure of the class described, ineluding a side rail, a supporting pedestal having a base plate adapted to rest on the ground, and a vertically projecting member and on which said side rail is adapted to be suspended.

3. A structure of the class described, in

' eluding a supporting pedestal having a base plate, and a stake passing through said base plate and provided with means for preventing complete withdrawal of the stake from cluding a supportin pedestal having a base plate, and a Stake a apted to slidably engage said base plate, and provided with means for preventing complete disengagement therewith.

6. A structure of the class described, including a supporting pedestal having a base plate, and a stake passing through said plate and adapted to be driven into the ground, said stake having a head at one end and an enlarged portion at the opposite end whereby the disengagement of said stake from the plate is prevented.

7 A structure of the class described, in-

cluding a side rail, a supporting pedestal hav- 1 ing a base plate, a portion of said base plate being adapted to project beneath the side rail, and means carried by the base plate for supporting the side rail in upright position.

8. A structure of the class described, including a supporting pedestal having a base plate and an upright member secured to said base plate, said member being provided with a laterally projecting rib.

9. A structure of the class described, including a side rail having a flange at the upper side thereof, a supporting pedestal having a base plate, and an upright member carried by said base plate and having its upper end adapted to form a seat for the flange of the side rail.

10. A structure of the class described, in-

cluding a side rail having a flanged upper side, a supporting pedestal having a base plate, and an upright member secured to said base plate and havin its upper end shaped to conform to the s ape of the side rail and to be inserted within the flange of said rail thereby to form a connecting means between two side rails.

In testimony that we claim the foregoing as our own, We have hereto aflixed our signatures in the presence of two witnesses.
