To alli/whom it may concern:

Be it known that l, FRANK P. KEMON, a

citizen'of the United States, residing at Atp for use in the erecting of'straight or b atmantling may tered walls, retaining walls, reservoirs, building foundations and walls, arch bridges, abutments, piers, houses, barns, garages, sewers, tunnels, viaducts, culverts, tanks, silos, lgrain elevators,etc.

The principal objects of my invention are, first, to provide concrete forms adaptable to all purposes of concrete construction; sec-l ond, to provide forms embodying elements which so coperate that erection andv disthird, to provide forms avoiding the use of detachable keys, pins or wedges as means for holding the parts in operative relatiorn'but utilizing such devices as bolts andv nuts of either the standard rtype or thumb-nuts, which may be maintained in screw-threaded engagement vith the bolts during and after dismantling, thereby rendering the forms inexpensive to provide and maintain them in workable conditions at all times; fourth, to provide forms of such construction that the concrete may be conveyed to the space adjacent or kbetween the form or forms and deposited without drop from a great height; fifth, to provide forms of suchconstruction embodying panels which may be removed at any point in the wall to permit of inspection,

or the placing of spouting, etc., therein; sixth, to provide forms of such construction that the panels may be progressively raised with respect to the uprights as the concreting progresses and becomes self-sustaining upon its base, eliminating the necessity of a large number of panels at any particular job; seventh, to provide forms with which standard rolled steel sections may be utiliZed, thereby enabling the bulk of material to be readily obtained in localities where manufacturing and construction work is in progress; and, eighth, to provide forms utilizing pressed steel sections which are light and durable, and which may be strengthened by wood llers, or upriglits when desired, such as where standard rolled sections are Specification of Letters Patent.

In the drawings, where similar characters refer to similar parts throughout the several views, A designates generally a suitable base, such as a channel section disposed'with its web uppermost; B, main supports or uprights formed of single rolled steel sections, or a plurality of sections; C, a cap for the main support; D, panels in abutting relation with and supported by said main supports or uprights; E, retainers, such as angle bars or members of angle sections, for holding the panels C in place; F, securing devices for the retainers by which they are permanently connected with the main supports' and held in adjusted position; and, G ties, longitudinally of the forms.-

It has already been purposed to utilize rolled steel sections in concrete forms, as well as pressed steel sections, and such has been brought into practical use, utilizing keys, pins or wedges for holding one part into operative relation to the other.

One of the principal objects of my invention is to avoid the use of such detachable devices, it having been found in practice that where such devices must be removed from engagement with essential parts of the forms, they become lost and a considerable outlay is necessary to replace such special detachable devices whenthe forms are again set up for practical use.

In the drawings, I have illustrated several modifications of main supports or uprights, to which the invention is applicable, and it is to be appreciated that changes in details may be made without departing from the spirit of my invention, as-hereinafter set forth.

The base A may be of any suitable section, preferably a channel, disposed with its webs 22 uppermost, the outer edges of the flanges 23 resting upon the ground. The Web of each base is provided with a plurality of perforations 24, one of which is shown in Fig. 3 to facilitate the attachment of uprights B to the base, as hereinafter described.

Referring lirst to the main supports or uprights, and more particularly to the forms shown iny Figs. 1, 2, 3, 4, 5 and 6, they com,- prise standard rolled I-sections, each including a web 25, longitudinal flanges 26 disposed nearest the hollow of the form, and outer flanges 27. Each upright is also provided with a plurality of ways 28, the opposite walls 29 of each way inclining toward the llanges 26. For a purpose to be subsequently set forth, I prefer to form the rest against flanges 26,

ways 28 of L-shape, the longer leg 30 of which is that bounded by walls 29, while the shorter leg 31 extends toward the flanges 27, and is preferably uppermost. In other Words, I prefer to dispose the Ways 28 1n the web 25 of each upright B in s uch a manner that one leg of each way inclines to-l Ward and with its closed end nearest flanges 26.

While I have shown the uprights B, 1n Fig. 1, as disposed in alined spaced-apart relation, and held rigid at their upper portion by means of cap C,it is to be understood that such cap may be dispensed with under certain conditions. The uprights may be secured to the base A as by angles 32, disposed at either or both sides of the web 25 of each upright, and with one leg 33, of each angle member 32, resting upon the web 22 of the base A. The other leg 34 of each angle 32 abuts against the web 25 of the upright, and both legs are provided with

perforations

35 and 36, respectively, the perforation 35 alining with a perforation 24 in the web of the base, While the perforation 36 alines with a perforation 37 in the web.25 of upright B. Through the

alined perforations

24 and 35, a bolt 38is passed, receiving nut 39, whereby the angle 32 is made rigid with the base. Through the alined perforations 36 and 37, a bolt 40 is passed, receiving thumb nut 41, holding the upright rigid with the base. The cap C may also be secured to the uprights in a similar manner, such as by angles 42, clearly shown in Fig. l.

As to the panels -D, they may be of any suitable material, such as pine planking 43, which may or may not be provided with tongues and

grooves

44 and 45,' respectively, and in heavyv Work, metal plates 46, secured to the wood backing, in any suitable manner, such as by screws 47. In practice, the panels are provided with reduced edge portions 48, which bringing the faces of the panels flush with the faces of said flanges, forming walls of the hollow when assembled.

In order to hold the panels in intimate contact with flanges 26, the retainers E are provided. They are preferably of angle section, and in a practical application of my invention, may consist in standard rolled steel angle sections, one leg 48, of each retainer, torest against the panel D while the other leg 49 rests against the web 25 of the upright. Each retainer is provided with a plurality ofperforations 50 so spaced that they may bel alined with the ways 28 of the uprights. The securing devices F, which have the dual function of permanently securing the retainers to the uprights, and also hold them in an adjusted position with re-A may be provided with spect to 'the panels, may comprisekeach, a 130 bolt 51 passing through alined perforations 50, and a nut 52, either of the standard type, or a thumb nut, as shown in Fig. 3. desired, a cottery pin 53 may be passed through 1and secured in an opening 54 adjacent the end portion of the bolt, so that the nut cannot be removed without first removing the vcotter pin, thus preventing accidental separation of the nut and bolt due to vibration.

t is to be observed that, with the shank of the bolt engaging the walls of ways 28, and more particularly the inclined walls 29 of said ways, by tapping upon the bolt heads or the upper portions of retainers E, they may be forced into intimate contact with the panels D which action, in turn, forces said panels in tight engagement with the flanges 26. When the nuts 52 are tightened, the panels are held securely in place. This adapts the uprights for use in connection with thick, medium sized, or thin panels, according to the character of the work, said inclined walls 28 enabling the operator to positively move the. retainers E either toward or from the 'flanges 26, while the legs 31- of the ways 28, enable the retainers E to be retracted sufficiently to remove any panel D. Likewise, by -releasingrthe nut 52, retracting the retainersany panel may be easily raised, enabling the panel to serve as a confining means for the concrete to be placed upon concrete which is already selfsustaining, that is, set, or the bulk' of which is supported laterally by the uprights B This enables the operators to progressively raise the panels D, so that very few are required in proportion to the magnitude of the undertaking.

Referring now in Fig. 7, the upright B is in the form of a rolled T-section, and is particularly adapted for lighter work. lt comprises the web 25, flanges 26 against which the panels D rest, ways 28 in web 25 retainers E and securing devices F. The only dierence between this modification and that designated B is the omission of flanges 27 and this modification is well adapted for use where great tensile strength is not essential..

n Fig. 8 the main support or upright B2 yis formed of two channels 55, the webs 25 of which are in abutting relation. Each channel is provided with the longitudinally eX- tending flange 26, against which the panels D rest, and/flanges 27 so that, in cross section, this modification resembles a ll' section. rl`he webs 25 are provided with ways 28, in this modification, formed to receive Vthe countersunk heads 56 of bolts 51, the usual retainers E being provided. This modified form of main support is well adapted for use in tunnel works where it is necessary to draw one section of the form into operative relation to the other, and for which purpose, the bolt 57 having a'nut 58 is provided, this comprise to the modification shown bolt passing transversely through the webs of the channels.

Pursuant to one of the principal objects of my invention, that is, to utilize standard rolled steel sections, where expansion occurs, or for the end of a form, as shown to the right of Fig. 2, the upright B3 may comprise a channel 59 provided with

flanges

26 and 27, andagainst the former of which panel D rests; the usual retainer E and securing device F, which latter also holds a. Z-bar 60, one flange of which abuts with the web of channel 59, while the other flange is in engagement with the outer face of the end panel D, this panel also resting against the web of the channel, as clearly shown in the drawings. lf desired, the turn buckle bolts 61 may be substituted for the usual bolt 51, and by the aid of a turnbuckle 62, joining bolt 61, the forms may be held rigid and drawn tightly into alinement. Likewise, the exterior corner upright B4 may comprisean angle 63, the interior face of which forms angular walls of the hollow, and suitable Z-bars 64, held in place by suitable securing devices F, in such a manner that one leg of each Z-bar abuts with one flange of the angle 63, while the other flange of the Z-bar engages the exterior face of panel D, this panel also engaging a portion of the angle section 63, as clearly shown to the left of Fig. 2. The interior corner main support or upright B may the same elements as upright B4 but disposed differently. angle sections 65 the exterior faces of which form wall portions of the hollow while the panels D are held in place by Z-bars 66 and securing devices E in a manner similar to that described in connection with form B4. The Z-bars are held in place with one flange in abutting relation to the interior face of the angle sections 65, with the other flange of the B section resting against the face of the panel.

In some sections of the country it may be desirable to utilize rather light rolled or pressed steel sections in conjunction with wood fillers or posts, and referringnow to the application of my invention to such a combination, uprights B6, to be interposed between corner uprights, may comprise a wood core 69, creosoted to preserve and waterproof the same, and to which are secured angle sections 70, one flange of each section, that designated 71, resting against the face of core 69, while the other flange 72 receives the side portions of panel D. Each flange 71 is provided with the usual ways 2S, which receive the bolts of securing devices F, coperating with retainer E for holding the panel in engagement with flange 72. The filler 69 is routed out, as indicated at 73, and more specifically shown in Fig. 21, to the rear of way 28 to make room for the head of bolt 130 j are provided with the usual desired. In the modification shown in Fig.

14, the main support or upright B7 is similar to that shown in Fig. 13, with the eX- ception that it is relatively narrower, and the Way 28 is continuous transversely of the main body portion of the structure, a single bolt 51 servmg to retain tWo of the E in place. In both forms B6 and B7, the angle sections may be secured to the core by means of bolts passing transversely through the structure, and having nuts 76 turned tightly against the flanges 71.

With forms using the Wood core, the corners may be constructed by providing an upright core 77 to the adjacent faces of which are secured angle `sections 7 8, so disposed that the margins of both exterior faces of said sections are in abutting relation, as clearly shown in Fig. 9. One flange 79 of each section 78 is secured to thecore 77 as by bolts 80 and nuts-81, and said flanges Way 28 for receiving the securing devices F, coperating with retainers E, and in conjunction with the other flange 82 of sections 78, for holding the panels D in place. The cores are also routed, as indicated at 83 for the heads of bolts used andl forming a part of the securing devices F.

If desired, as shown in Fig. 12, the bolts 51 may be provided with countersunk heads 84:, and under which conditions the routing 83 as shown in Fig. 9 is not necessary.

Interior corners utilizing Wood cores may be formed as shown in Figs. 16 and 17, Where the Wood core is indicated by character 85. Angle sections 86 are secured to 4adjacent faces of the core but with the face of one flange 87 in alinement With, or in close proximity' to the opposite face 'from that to Which the other section 86 is s ecured. The other flange 88 of each section 86 is provided with the usual Way 28 to accommodate the securing device F also cooperating With retainer E, for holding the panels D in place. The core is routed out as indicated at 89 to receive the bolt heads of bolts 51. The sections 86 may be secured to the core 85 as by bolts 90 and nuts 91, as clearly shown in Fig. 19, and under which conditions the core 85 may beprovided with a recess 92 for the heads of bolts 90, these recesses being closed by means of an angular plate 93, secured to the core 85 in any suitable manner.

It may be desirable to further modify this combination of Wood and metal in the provision of main supports such as is shown in Fig.f19, B11 being a form of supports to be interposed between corner supports, and comprising a core 94 of Wood, with flanges 95 adjacent the faces thereof, flanges96 exelements tending longitudinally of the core 91, and against which the panels D abut, bemg of one continuous sheet of metal which also the modification of the corner posts for the exterior of the form it compr1ses the core 99 of Wood With a shell or casing of sheet metal 100 about the core and having its end portions doubled upon itself, at right angles, forming flanges 101 against which the panels D abut. The core, as Well as the shell is provided with the usu'al Way 28, and the securing devices are here shown comprising bolts 51 extending entirely through the core v and shell portions, and receiving the nuts 52 adjacent retainer E which is formed as described in connection with the sup ort B11. The internal corner support or'uprlght may comprise a Wood core 102, With a casing of sheet metal 103, doubled upon itself adjacent the center. portions, providing flange 104, and having one end portion doubled upon itself providing flange 105, the ends of the sheet metal joining as indicated at 106. The core 103 is recessed as at 107, to the rear of theyvvays 28 for the securing devices F, which coperate with the securing devices E.

It is to be understood that, in connection With any of the main supports-or uprights, utilizing Wood as a core, or to give tensile strength to the members, the metallic portions can be formed and assembled into operative relation to the Wood cores obtained at the locality in which the metallic portions are shipped. In this Way the members of the forms can be adapted to the particular Work, and to withstand the load.

The invention is susceptible of manyl changes and modifications which may be spirit or scope of my invention; but,
