STEEL WALER AND CLAMPING MEANS Filed Sept. 8, 1950 2 SHEETSSHEET 2 Patented Mar. 17, 1953 UNITED STATES ATENT OFFICE STEEL WALER AND CLAMPING MEANS Chester I. Williams, Grand Rapids, Mich. Application September 8, 1950, Serial-No. 183,736

13 Claims.

' My invention relates to clamping and locking devices for concrete construction forms, and has among its objects the production of a simple and durable construction which willhave a long life, and is adaptable for repeated uses.

The same has particularly as an object a form clamping device of great strength. and rigidity, compact and usable with or without the studding generally used in form constructions.

The same has among its further objects a clamping device which may be readily and conveniently applied or removed.

A further object is a form. clamping device of the kind described in which steel or like channel walers are used, preferably in pairs, as shown.

Another object is the productionv of a construction in which the walers may be conveniently and readily locked together on the form, and maintained in engagement, with tie or form rods and form walls without the use of; nuts, or like fastening members. 1

A further object. is the production: of a form clamping device in which the tie, rods may be secured directly to the walers, maintaining the walers in secure assembly with; the. form sheathing and with. one or more: studdingmembers, or without the studding.

Many otherobiects. and-.advantagesnof the constructions herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention. consists in the novel construction, arrangement; and combination of parts herein shown and described, and more particularly pointed outin the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a sectionalview through. one side of a form takenv substantially on. line l'..l of Fig. 2, and illustrating the use of a single studding;

Fig. 2 is, a. sectionalview; taken. substantially on line. -2 f; Fi 1.;

F g. 3 s. a sectionalviewv similar to Fig. 1,.illustrating the omission;v of studding, taken substan-. ally on inlet- 3. of F I;

Fig. 4 is a sectionallviewz taken substantially on line 4-4 oi Fig.3

Fig. 5 is a view similarto Fig. i illustrating a modified form of means for securing the walers together, the same being taken substantially on the line 5-..5 of Fig. 6.;

Fig. 6 is a sectional view taken substantially on line 66 of Fig. 5; and

Fig. 7 is a view in elevation of a locking device shown in Figs. 5 and fi.

Referring to the drawings, and first to Figs. 1 and 2, in which only one sideof the form is shown, it being understood, however, thatwhile the opposite side isordinarily the same as shown in Figs. 1 and 2, it may be modified without departing from the spirit. of; the invention, I represents sheathing, ordinarily of plywood boards, sheet metal, or their equivalents. A stud 2 is shown bearingagainst the sheathing, it also being understood that the studs may' be in pairs. The walers are each preferably-in two parts or pairs, such as steel channel'shaving side flanges 4 arranged with the free edges of the flanges extending toward eachother, but with a space between. There is also shown a form tie rod 5 engaged by a tie rod extension 6, as for example, a screw threaded engagement. type of tie rod or extension and connecting means maybe employed. The rod 6 extends through the sheathing I at each side and at the exterior of the form, and in between the walers 3. In the construction illustrated; the rod 6 is notched at each side, as indicated at I, the flanges 4 of the two walers engaging inthe notches, the waler, as shown in Fig. 2' bearing against the studding 2. To look the walers, 3 together, as well as to lock the. form sheathing, tie rods andstudding to the walers, alocking member 8 is provided adapted to. engage the faces of the channeled walers. The particular locking member 8 shown, is flanged at: 9 and. aperturedto permit the rod 6 to pass therethrough. The member 8 is shown locked on the tie rod 6 by means of a nail It, or any equivalent for. the purpose. The tie rods thus rigidly tie the two sides of the form together, and maintain the walers in engagement with the studdingZ.

The construction in Figs; 3 and 4 is similar except that, as. shown, the'walers 3 bear directly againstthe sheathing I, the'studding being omitted. Insome construction jobs it may be desirable to employ the studdi-ng, but in other jobs, the studding may be omitted and the walers maintained against'the-out'er face of the sheathing. Obviously, studding' may be employed at both sides of the form, as shown in Fig. 1, or without studding, as shown in Figs; 3 and 4, or with one side of the form arranged as shown in Fig. l withstudding, and the other side of the g rmgmaintained without studding, as shown in In the construction shown in Figs. 5, 6 and 7, the locking member G, shown in Figs. 1 to 4,, is not employed, butin this case the walers, 3 are maintained inassembled-relation by bolts II, or

their equivalents, connecting the channels 3. The bolts I I are rigidly secured to one of the members 3 by nuts I2, it being obvious the same may be secured in any equivalent manner. Referring to the figures, a cam lever I3 is provided with a bifurcated end hi embracing the end II of the bolt II, the lever I3 and bolt II being secured together by means or rivets I 5, or their equivalents. As shown in Fig. 7, the lever I3 is so designed that the cam I4 maintains the waler members or channels 3 firmly together, with the flanges 4 engaging in the notches "I of the rod 6, securely locking the tie rods and form parts together. To release the same, the levers I 3 are swung to move the cams away from the adjacent member 3, whereby the waler members 3 may be separated sufiiciently to release the'rods 6, permitting the removal of the rods 6 from the form and permitting the walers to be employed again on a form.

As in the constructions previously described, the studs may be employed or omitted, as desired, at one or both sides of the form. The construction shown in Figs. 5, 6 and '7 has an advantage over that shown in Figs. 1 to 4 in which figures the locking member 8 is employed, in that the walers and clamping means provide a unitary structure, it being unnecessary to remove the bolts and levers I3 when applying or removing the walers from the form.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
