His 31- lhc iiiiiei' nice thereof. in

outer xm-iiun in form an air space "50 thni when 1hr latter is l" lugs Ff sh ps .i min carried alon in an upward direction. In order to hold the inner boards D, D spaced apart while filling concrete material between the corresponding boards B, D and O, I), use is ma e of s acing plates K provided with heads'K' a apted to rest on the top edges of the boards D, D, and reaching with their terminals to the inner faces of thel plates E, E and which plates practically clamp the heads K in transverse osition. The ower edges of the inner boarc s D, D are provided with notches D to allow the insertion of binding keys L of any approved material, to unite the wall sections A and A with each other at suitable intervals, as indicated in Fig. 1.

The boards or plates B and C are liable to warp, and in order to bring the same into proper alinement use is made of angle irons or rails N, extendin along the lower ends of the boards B an C and secured to the lower ends of the reinforcing bars F (see Fig. 4). Thumb screws N screw in the angle irons or rails N against the outer faces boards C and D. After the'material hast of the boards B and C, to enable the operator to bring the boards B and G into a straight line position, thus insuring the formation of straight walls The boards B and C as well as the plates E and E are connected at the corners of the wall sections A and A by suitable fastening devices, such as apertured lugs O and removable keys 0, as p ainly indicated in Fi s. 3, 8 and 9.

In case the inner boar not join properly atthe corners of the wall sections and A, then use is made of angle plates P (see Figs. 2 and 11) having lugs P at their u per ends for supporting the angle lates P rom the top edges of the boards D,

Joint plates Q are used on the adjacent ends of the boards B and C, as indicated to the left in Fig. '2, but other suitable means may be employed for the purpose.

in order to provide a. facing A of a finer cementitious material than that,- used for building the main portions of the wall, use is made of plates R (see Figs. 1 and 7), arranged spaced from the inner faceof the facin board B, the lates R overlapping one t e other in the direction of the length of the mold, as indicated in Fig. 7. Each of the plates R is rovided at its top with an outwardly-extending flange B extending over the to of the board B, and each flange is provide with an aperture R for the insertion of a pin or a rod S extending downward between the opposite faces of the correspondin plate R and the board B, so that the plate K is spaced from the board B corresponding to the diameter of the pin S. Now in forming the outer wall section A the concrete or other eementitious material is; filled in between the board D and the plates R, and a like material is filled in between the s 1), n, n, n do,

loosen the plates Lt.

somewhat set the plates 11, and the pins S are removed and then the space between the outer face of the wall section A and-the inner face of the facing board B is filled in with fine cementitious material, 'which readily adheres to and forms the facing A for the wall sectiou A, as plainly indicated in the lower portion of Fig. 1.

fter the outer and inner wall sections A and A have been lillcd to about the height of the boards B. C, l) and D, then the mold is raised by the use of the screw rods 1 and the foot boards J resting on top of the wall sections just finished. By having two screw rods I on each cross bar l1 and turning the same sinuiltaneously, it is evident that the mold is properly raised without danger of moving any of the boards in a transverse direction, that is, the boards are raised vertically until the lower endstof the boards 13, C, D, 1) contact with the upper portions of he wall sections A, A already built, as will be readily understood by reference to Fig. 1. The keys L are set in position immediately previous to starting the next course for the wall sections A and A, so that the keys are partly embedded at their ends in the two succeeding courses.

From the foregoing, it will be seen that by the arrangement described, the wall can be readily built in sections spaced apart to form an air space, the enter section can be provided with a facin of finer material than that forming the body of the wall, and the wall can be readily built u in courses to any desired height by perio ically raising the mold on the operator turning the screw rods 1, as above explained.

If desired, the inner face of the facing board B may be made in step form, as indicated in Fig. 12, so as to give the outer face of the wall section A a clapboard appearance, otherwise the construction of this is the same as before described, except the the plates R and the pins S are omitted.

By providing the boards B and C with the rail N and adjusting screws N, all leakage of the concrete material and facing material is prevented, and by arranging the plates R and the ins S in the manner described,-the plates are firmly held in place while filling in the concrete material for the wall section A, and when this has been finished the pins S can be readily pulled up, to and thereby allow their convenient withdrawal for the subsequent filling of the facing material. It will also be noticed that by haviiw the rigid frame 1) locked to the upper cues of the reinforcing bars 15, the mold boards B and C are firmly held in position, to insure the formation of perpendicular wall sections without requiring adjustment of the parts of the mold.

The reinforcing bars F are prfgrably t t g t t t t l 10. A wall mold; comprising a facing board, a rear wall board, intermediate boards, spacing devices for the said intermediate hoards, vertical bars on the said facirig board and the said rear wall board and projecting beyond the top thereof, the upper ends of the said vertical bars being provided with inwardly extending hooks for the boards to swing outward, a top frame having plates connected with each other by cross bars. the top frame plates resting on the said facing board and the said rear wall board, the cross bars having apertured lugs for engagement with the said vertical bars, and keys for fastening the said lugs to the said vertical iriltS.

12. A wait mold having a facing board, a rear board, vertical oars secured to the outer faces of said boards and extending beyond the tops thereof, rails secured to the lower ends of the said bars and extending along the lower ends of the boards, screws screwing in the said rails and abutting against the outer faces of said boards, a top frame resting on the said boards, and means for removably securing said frame to the extensions of said rertical bars.

13. A wail mold comprising 21 facing board, removable plates held spaced from the inner face of the facing board, a rear board, vertical reinforcing bars on the facing board and the rear board and projecting beyond the tops thereof, a top frame having plates resting on the facing board and the rear board, cross bars connecting the plates and having apertured lugs for engagement with the said reinforcing ban, and means for removabiy securing the lugs to said reinforcing bars.
