G. DIETRIGHS. APPARATUS FOR GON'STRUOTING WALLS OF CONCRETE.
APPLICATION TILED NOV. 17. 1906.
my/i/m qvilucmwa UNITED STATES PATENT O FICE CHARLES DIETRICHS, oF' LITTLE FERRY, NEW JERSEY.
APPARATUS FOR CONSTRUCTING WALLS OF CONCRETE.
To all. whom it may concern:
Be it known that I, CHARLES DIETRICHS, a citizen of the United States, residing in Little Ferry, Bergen county, New Jersey,-
object the provision of a paratus by which the" construction of wa s of concrete or other plastic material may be earriedfon.
use of apparatus hereinafter described and illustrate in the accompanying drawings, in which corresponding parts are designated by similar characters of reference in the several views.
In the drawings: Figure 1 is a fragmentary perspective view of a portion of a wall in process of construction with the' improved apparatus forming the resent invention, a part of the wall being broken away to show the arrangement of the devices within the wall for securing the mold members- Fig. 2 is a fragmentary sectional view through a portion of the wall and the mold members and securing devices. Fig. 3 is a detail view showing a modified form gf connecting link for opposite moldmemers. Y Inthe construction of walls of concrete or other similar lastic materials, a mold or casing must aways be prepared to retain the concrete in form during the process of setting, and in the construction of this mold or casing planks or boards of suitable thickness are ordinarily employed. Theboards or planks may be nailed to uprights bi'aced from the outside, or. securing devices of similar character may be braced between the sides of the mold or casing to hold the boards or planks in place. The connecting devices employed in this way are of various kinds, and they may either be withdrawn from the wall after the removal of the moval, it is desirable to make use of con-- nectmg devices consisting in the main of an Specification of Letters Patent.
Application filed November 17. 1906. Serial No. 343.806.
fatented Nov. 19, 1907.
nexpensive connecting link which may be left 1n the wall when the boards or planks forming the sides of the casing or'mold are removed. It is also desirable that the devices associated with the link to be left in the wall. shall be of such construction that they may be quickly brought into engagement with the link or disengaged therefrom. The devices cooperatin with the link should also be so designed t at their disengagement from the link will not niar the wall inany way and so that after the removal of the mold members the marks left in thewall by the devices for'securing the mold members may be easily obliterated.
The objects above mentioned are attained in the apparatus constituting the present invention.
Referring to the drawings by the reference characters, 11 are boards or lanks used in forming the sides of the mol into which the concrete is introduced. These boards extend horizontally, as usual, and each one is provided nearits upper margin with fixed cleats 2 in suitable number. Near thelower margin each of the boards or planks l is provided ,with a number of cleats 3 whichmay be turned laterally about the single rivet or blolt which forms the fastening device for the 0 eat.
Near the upper margin of each board I provide a suitable number of hooks 4 of special design, each of which is mounted in a horizontal curve 5 and turns about a vertical pivot 6. These hooks 4 are designed for en agement with eyes formed in the ends of links 7 which extend transversely of the wall and are of a length slightly less than the thickness of the wall. The engaging portion 8.0f each hook is slightly tapered, as shown in Fig. 2, and itsouter edge is formed on a circular curve having the pivot 6 as a center. The eyes in the ends of the links 7 areof such dimensions that the engaging portions of theportion 9 by which the hook may be readily turned in order to effect the engagement or disengagement of the hook and link.
In making use of the apparatus described, boards to form the lust course of the mold on the lowermost board in Fi 1.
are set up at the proper distance apart and secured at their lower edges in any suitable manner, and at the upper margin they are of the second course of boards the pivoted.
lugs 3 are turned into position to engage the boards of the first course By proceeding this manner. as many courses of boards may be set in place as may be desired. Or-
dinarily, however, the boards will be set'in place by single courses, and after the placing of each course an additional quantity of concrete may be introduced. When the concrete in the mold nears the top of the mold members already in place, as shown in Fig.
1, another course of boards will be set in.
place. After the boards at the base of the wall'liave been in position long enough to permit the concrete to set firmly, those boards may be removed and used again in extending the'mo'ld upward. To disengage the course of boards the hooks are turned 1nto the position shown at the top of Fig. 1, thus disengaging the hooks 4 from the links 7. The pivoted lugs 3 engaging the upper margins of the boards to be removed are swung into horizontal position, as shown The boards to be removed are then qulte free and can be removed laterally away from the wall without difliculty. After the removal of a course of boards the 'wall is left perfectly smooth and-unmarked except for the small openings left by the withdrawal .of the engaging portions of the hooks. These small openings may easily be filled by the applicat1on of a little cement and when thoroughly dry will show no trace of the openin s.
As shown in Figs. 1 and 2 the Iin s 7 are formed of sheet metal with the eyes punched therein. satisfactory, is only a typical form. A link 10 of'wire is shown in Fig. 3 which will serve the same function as the sheet metal links 7.
From the foregoing description and the accompanying drawings it will be. seen that the devices employed for securing the mold members are of a character to permit .the securing and removal of the mold members with the utmost facility, and the condition of the wall as left when the mold members are removed is of most satisfactory character. requiring This form of link, While eminently only the application of a very little cement inv the small holes left by the hooks .4 to complete the finish of the wall. These holes need not even be filled, as the strain on the mold members during the construction of the wall is not very great and the hooks may be made of such dimensions that the holes left when they aredisengaged will be unnoticeable except on close inspection. Owing to the formation of the enga ing portions of the hooks on circular curves a out the axes of the hooks as centers, the outward movement of the hooks is not opposed bythe concrete or the wall and. no injury to the wall results from the movement of the hooks. As the hooks and cleats are the only members required in addition to the. links to secure the mold members in place, there is no danger-of delay in securing the mold members on account of the loss or misplacement of any of the securing devices, the cleats and hooks all being firmlysecured to the boards forming the sides of the mold or casing for the wall.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. The combination, in apparatus of the character specified, of oppositely-arranged mold members, hooks pivoted on said mold members. and adapted to swing in a plane perpendicular to said mold members, and a nk adapted to be engaged by said hooksto hold the mold members in position.
'2. In apparatus, of the character specified, the combination with oppositely-arranged mold members of hooks pivotally inounted on said mold members'to swing in a plane perpendicular to said mold members, said ooks each having the engaging portion of the hook extending inwardly between the mold members and having the handle por tion extending outwardly beyond the mold Inembers,.and a-linkadapted to be engaged by said hooks and held between said mold members.
3. In apparatus of the character'specified, the combination with o 'ositely-ar-ranged mold'members of pivote ooks carried by said mold members and arranged to swing in a plane perpendicular to said mold members said hooks having their'engaging portions formed on circular arcs with the hook pivots as centers, and a link adapted to be engaged by said hooks. p
' In testimony whereof, I have signed my name in the presence of two witnesses.
