The device comprises a group of four longitudinal rails, the respective members of .which are connected to the members ofa group of four transverse rails. As shown in Figs. 1 and 2, the left hand longitudinal rails comprise an upper rail or angle iron 10 and a lower rail 10 The right hand longitudinal rails cqmprise a bottom member 25 and atop' member 25. The transverse rails comprise two front rails 11 and two rear rails 10. i q

The left hand longitudinal rails 10 and 10 are directly connected to the rear transverse rails 10 by means of suitable detachable fastening members F. 'The right hand longitudinal rails 25 and 25' are connected to the front transverse rails 11 by means of intermediate coupling members, each of which consists of two angle irons. For example, and as shown in Fig. 1, the top rail 25 is connected to a lower rail 24 by means of clamp bolts 23 which pass through slots 26 and27 in the lower rail member 24. As clearly shown in Figs. 1 and 3, the top rail member 11 is connected to a rail member 20 located directly beneath it, by means of similar bolts 23 which pass through slots 21 and 22 of the rail member. 20. Similar intermediate connections are provided between the rails 25 and the lower rail 11. The rails 20 and 24 are connected to each other by detachable fastenings F and the rails project beyond F and abut the faces of an upright angle iron 13 which forms the" inner corner member of the form. It is not necessary to provide any fastening means between the member 13 and the upper and lower pair of rails 24 and 20' because the configuration of the parts provides the necessary firm frictional fit. 'lhe inner corner member 13 is associated with an outer corner member 12 also made of angle iron and the rolled end flanges of the member 12 abut the adjacent B which extend through notches in the ad- I jacent rails which are held in clamped position by means of nuts N. By shifting the I rails 24 and 20 with respect to their adjacent and connected rails, it is obvious that the position of the inner corner member 13 can be varied when the spacing between the rails is varied, so that the device can be used for forming walls of varying thickness. The horizontal rails before mentioned are connected to upright channel irons 16 by means of fastening devices shown clearly in Figs. 4 and 5. The parallel webs of the upright channel irons 16 are provided with inner U- shaped bars 17 having sleeves 18 provided with pivot members 18 by means of which bars 17 are pivotally connected to said uprights 16. The sleeves 18' are provided with bolts 18 which project through slots in the horizontal rails so that the uprights 16 can be clamped to the rails by means of wingnuts 18. The uprights can be clamped-to their rails by means of ordinary nuts N instead of wing-nuts 18 shown in Figs. 4 and 5. p

The uprights 16 are held in spaced position. by means of intermediate sleeves 34 and end sleeves 35 which are externally tapered. Bolts 36 extend through the members 34 and 35 as shown in Fig. 14 and nuts N are provided forv firmly clamping the uprights 16 together.

The spaces between the uprights 16 are filled by means of upper panels 28 and lower panels 29. These panels 28 and 29 are provided with external strengthening corrugations 14 which are secured thereto by means of rivets 30. As shown in Fig. 1 the ends of the panels fit between the internal flanges of the uprights.

The parallel'webs of the uprights 16 are provided with perforations 32 in which pins 32 are fitted. Forked members 31 are provided with bases 31 which can fit slidably upon the webs of the upright channel irons 16. The forked ends of each said fastening member are adapted to engage one of the said pins" 32 as shown in Fig. 3; for example, and these forked ends are wedge shaped so that upon forcing each member 31 into position it firmly'holds one ofthe panels in position. The wedging members 31 are held in the position shown in Fig. 3, by friction. In order to securely lock the panels into position,. it is preferable that the members 31 should be inclined when they are in the locking position and hence the bases 31 of the members 31 are provided with screws 33. These screws have wing-shaped ends so that they can be adjusted with respect to the bases 31 and the adjustment of these screws regulates the inclined position of the respective members 31. y

In order to more securely hold each panel in'position, the device shown in Figs. 12 and 13 can be provided. This consists of a mem- I ber 47 having chain members 45 which can be'caused to engage the o enings 32 in adjacent uprights, 16. A bo t member 46 can be adjusted with respect to the member 47 so that each panel is forced against the adjacent'uprights 16 with great force.

Platform members 42-can be caused to engage horizontal pins 43 passing through Figs. 6 and 7 adjacent superposed uprights 16 and 16 are provided with an intermediate U-shaped connecting member 37 which fits snugly between the flanges of said uprights 16 and 16 A bent and re silient member 39 fits between the flanges of the inner connecting member 37, and pins 41 which pass through openings 32 in channels 16 and 16 and through slots 38 in members 37, limit the outward movement of members 39. Member 39 is provided with threaded members 40 which tend to force member 39 outwardly when said threaded members 40 are turned, so as to clamp the members in the position shown in Fig. 7.

In the embodiment shown in Fig. 16 one of the corner channel members such as the member 12,. is formed of two separate lates 12 and 12 connected together by linge members 15. This construction enables walls having obtuse or other angles to be formed, in addition to the construction shown in Fig. 1. which enables walls having right angles to be formed.

The use of both of the inner rails and the outer rails is not necessary in all cases. For example, if an excavation has been made for a foundation, the wall of the excavation can replace the outer rails so that only a s ngle set of mner rails need be employed in such clrcumstances. When v.the form has been set up, concrete or other plastic material is poured in between the panels and after the wall has set everything can be removed exce t the sleeves inter mediate the upright channels, as shown in Fig. 15.

We have shown a preferred embodiment of our invention, but it is clear that numerous changes and omissions could be made without departing from its spirit.
