UNITED STATES PATENT FFICE.
CHARLES F. LONG- AND ALDEN B. HERSMAN, OF LOS ANGELES, CALIFORNIA.
CONCRETE-FORM CONSTRUCTION.
Specification of Letters Patent.
Patented Mar. 30, 1915.
Application filed January 2, 1913. Serial No. 789,612.
To all whom it may concern Be it known that we, CHARLES F. Lone and ALDEN B. HERSMAN, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and usefvl Improvements in Concrete-Form Constructions, of which the following is a specification.
This invention relates to concrete form constructions, and more especially to knock-- down constructions for building pillars, and the principal object is to provide a simple and eflicient binder or clamp for securing and holding the longitudinal walls of the form in assembled position.
It is a further object to provide such abinder or clamp in sections which are joined together by a flanged union and held se curely by easily removable pins.
In the drawings accompanying this specification and forming therewith the application for Letters Patent: Figure 1 is an elevation of a portion of a form showing a plurality of clamps in position thereon. Fig. 2 is a transverse section through the form illustrated in Fig. 1, on a larger scale. Fig. 3 is an elevation of the clamp alone in assembled position. Fig. 1 is a cross-section of an octagonal form showing the application of the invention to this construction. Fig. 5 shows a clamp applied to a form of circular cross-section. Fig. 6 is a detail perspective view of a square corner brace or connector.
In the drawings numerals are used to designate the component parts, 7 designating the planks used to form the walls of a rectangular or square pillar, which are placed in a vertical position with a por tion overlapping at the corners 8, these corners preferably overlapping in succession, as clearly shown in Fig. 2. To secure the latter in a proper relation a suitable block or spreader, not shown, is placed on the ground, of a size corresponding to the crosssection of the pillar it is desired to build within the form. The planks 7 are now placed in position surrounding this block, and one of the improved clamps formed of the cross bars 9 transversely disposed, are placed in position resting on the floor or table on which the planks 7 rest, in a square structure, four of these bars being used, their ends being suitably mitered at the point 10 to form the square frame surrounding the boards 7. The cross arms 9 are provided with suitable bores 11 adjacent their mitered ends, which register with similar bores 12 in the top plate 14: of the angled connector 15. This connector is preferably formed of the two mitered walls 16, which are joined together and secured, by means of the top plate 1a to exactly fit the mitered ends of the bars 9 forming a corner over which the connector fits and is supported by means of the plate 14. The lower portion of the connector has no connecting plate, being preferably open so that it can rest on the floor 17, the same as the bars 9, used in this lower position.
The pins 18 are provided to pass through. the openings 12, which, as before stated, register with the bores 11 in the bar 9, the pins being preferably slightly tapered so that they do not fall through the bores but have sufficient frictional engagement with the top plate to hold them in their proper position.
In the form shown in Fig.4: the bars 19 forming the connecting members of the clamp are of a length similar to the bars 9 or corresponding to the width of the eX- tended face or side of the concrete pillar formed in the mold, the ends being mitered to form a complete inclosure, and the connectors 20 are built similar to the connectors 15, the angle varying to suit the angles of the face of the form.
In Fig. 5, a circular form is shown, built in the same manner, the walls 21 being necessarily curved in their cross sections and the bars 22 being preferably built as quadrants to surround the planks 21, the connectors 23 being provided with openings registering with openings in the quadrants 22 and secured by suitable pins 24, as described, in the rectangular type.
The ends of the bars 9, 19 or 22 abut against the ends of their companion bars and the abutting faces are formed in radial relation to the center of the inclosure formed by the mold panels; the bars thus being of corresponding dimensions and pattern for each form of mold thereby being interchangeable. The connectors are also formed of corresponding pattern according to the form of mold and by reason of being adapted to be demountably attached to the bars at the abutting ends of the latter by a line in radial relation to the center of the area inclosed by the Walls, said bars being provided with bores adjacent their abutting ends, separable connectors having plate portions adapted to extend over the abutting ends of the bars and having Walls adapted to extend alongside the outer faces of the adjacent bars, said connectors being provided with bores registering With the bores in the bars, and tapered pins insertible in said registering bores, whereby the abutting ends of the bars are detachably connected together.
In Witness that We claim the foregoing We have hereunto subscribed our names this 17th day of December, 1912.
