REY IE1. CALLAGHAN, OF DENVER, COLORADO, ASSIGNOR- OF ONE-FOURTH TO CLEMENS SITTERLE. OE DENVER, COLORADO.
FORM FOR CONCRETE.
Application filed. August 17, 1923.
To all whom it may concern:
Be it known that I, R X E. GALLAGHAN, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Forms for Concrete, of which the following is a specification.
This invention relates to devices for molding concrete and is more particularly applicable to the construction of dams, retaining walls and other structures requiring a long vertical wall.
It has for its principal object the provision of a device of this character which can be readily assembled to suit varying conditions and the use of which is continuous, that is, the sections in which the concrete has become set can be removed and carried ahead to position for fresh concrete, thereby reducing the number of sections necessary to complete the job.
Another object of the invention is to provide a concrete form which will be elastic in its application as to height, width and length.
A still further object is to provide sectional walls for a concrete form which may be forced into the earth and as the excavation progresses can be added to until the form is completed.
Other objects and advantages reside in the detailed construction of the invention, which result in simplicity, economy and efliciency, and which will become more apparent from the following description.
In the following detailed description of the invention reference is had to the accompanying drawings which form a part hereof. Like numerals refer to like parts in all views of the drawings and throughout the description.
In the drawing Figure 1 is a perspective view, showing the sections of the form in the erected position.
Figure 2 is a detailed perspective view of the connections used between several parts of the form. I

termed the connecting link which is used to secure the various series of sections together.
Figure 7 is a side elevation of the same.
Figure 8 is a plan view of the two sections of the gate used to separate the various sections of the form and also used as an end gate at the terminal of the structure being built.
Figure 9 is a side elevation of the same.
Figure 10 is a fragmentary detail view of a joint between form sections showing the manner in which the joint is protected from the concrete when the form is poured.
Figure 11 is a detail sectional view through the lower edge of the lowermost form, showing the shoe used when the forms are driven into the ground.
Figure 12 is a detail view of the spacing bar for holding the form sides in spaced relation.
The invention comprises a series of form sections, designated by the numeral 12, comprising end members 13 connected by means of side plates 14 and separated throughout their length by Z bars 15. The width of the form sections diminishes toward the bottom; the outer wall thereof being vertical; the inner wall slanting, so as to form a tapered mold for the concrete.
The end members 13 of the form sections 12 are provided with vertical grooves 16, T-shaped in cross section, and adapted to re ceive a connecting link 17, shown in detail in Figures 6 and 7, the edges of the connecting link being T-shaped in cross section to fit snugly in groove 16.
On the inner face of the form sections 12 are secured pockets 18 for the reception of hooked shaped extremities formed on turnbuckle rods 19.
Formed in the connecting link 17 is a vertical T-shaped groove 20 adapted to slidably receive the extremities of a sheet metal gate 21, shown in detail in Figures 8 and 9,'and comprising two sections,o ne edge of each of which is T shape in cross section formed by riveting angle irons 22 along both sides of said edge. These angle irons 22 engage in the groove 20 in link 17 when use; The two sections of the gate 21 are connected when in place by means of latch bars 23, as
shown in Figure 9. The purpose of forming the gate in two sections is to facilitate its insertion in the groove 20.
In use two of the form sections 12 are placed parallel to each other, separated a distance equal to the desired thickness of the finished concrete wall, and are held in spaced relation by means of beams 24: placed therebetween, directly above the sockets 18. The turn-buckle rods are drawn up to securely clamp the beams 24 in place.
Connecting links 17 are now placed in the groove 16 in the end members 13 of the form sections 12 and additional sections secured to the connecting links. This process being continued until the desired length of term is reached. The gates 21 are now placed in position in grooves 20 of the links 17, as shown in Figure 1.
Should it be desired to excavate for the proposed wall the excavation is now commenced between the parallel form sections, and as it progresses the form sections are driven down and additional sections placed on top thereof.
It will be noted that the end members 13 are each provided at their one extremity with a tongue 25, which engages in a socket 26, formed in their other extremities, as each of the form sections are added, the
.tongue 25 being held in place in the socket 26 by means of a bolt 27, which passes therethrough. As additional form sections are added, additional connecting links 17 must also be added between the additional form sections and connected to the preceding links by means of bolts which engage openings 31 formed in the links and in straps 28 secured thereto, as shown in Figure 7.
To facilitate the forcing of the form into the excavation steel shoes 32 may be used in the lower-most form section, as shown in Figure 11. When the form has reached the height of the desired wall and the excavation has been completed the gates 21 are rc moved and T irons 29 of special construc tion are placed in the grooves 20 of the oint opening between the various sections and prevent concrete from entering the grooves, as shown in Figure 10. The beams 24 and turn-buckle rods 19 are also removed wher ever possible. Should the exterior pressure on the form be so great that interior bracing is necessary metal beams or pipes could be used in place of the beams 2 and left in place when the concrete is poured.
After the form has been poured and the concrete has set, the links 17 are withdrawn, thereby disconnecting the various form sections from each other and allowing them to be readily withdrawn. The sockets 18 being turned downward will pull away from the hooked shaped extremities 01 the cross rods 19, should they be left in place, and allow the forms to be removed.
Should it be desired to make a right angle turn with the forms the connecting links 17 could be formed on a longitudinal rectangle, so as to allow the connecting form sections at this point to project at right angles. The upper edges of the upper forms are held in spaced relation by means of cross bars 30, the extremities of which project downward at right angles and engage the co-acting sections.
While a specific form of the improvement has been described and illustrated herein it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent is 1. A sectional form for concrete comprising side sections; vertical grooves in the ex tremities of said sections; detachable vertical links engaging in said grooves and connecting said side sections; gates connecting said links at the opposite sides of said form and means for holding the sections at opposite sides of the mold in spaced relation.
2. A sectional form for concrete comprising side sections; vertical grooves in the extremities of said sections; detachable vertical links engaging in said grooves and connecting said sections; vertical grooves formed in said links; lateral gates detachably engaged in said grooves in the links at the opposite sides of said form and means Inc for holding the sections at opposite sides of the mold in spaced relation.
3. A sectional form for concrete comprising side sections; vertical grooves in the extremities of said sections; detachable vertical links engaging in said grooves and connecting said side sections; gates connecting said links at the opposite sides of said form and means for holding the sections at opposite sides of the mold in spaced relation, said means comprising beams held in place by turn-buckle rods engaging sockets on said sections.
4:. A sectional form tor concrete comprising a series of sections having vertical T- shaped grooves formed in their extremities: connecting links formed with T-shaped edges for engaging in said T-shaped grooves and connecting the adjacent sections, said links containing vertical T- shaped grooves and a member arranged to engage in the groove in said links and cover the joint between said adjacent sec tions.
5. A sectional form for concrete comprising a series of side sections having vertical T-shaped grooves formed in their extremities; connecting links formed with T- shaped edges for engaging in said T-shape grooves and connecting the adjacent sections, said links containing vertical T- shaped grooves and lateral gates for traversing said form, said gates having T- shaped edges for engaging in the groove in said links.
6. A sectional form for concrete com-prising side sections provided at their top and bottom edges with tongues and grooves so as to interlock with each other and having 10 openings in said tongues and grooves for the passage of bolts to lock said sections together and means for holding the sections at the opposite sides of said form in spaced relation.
In testimony whereof, I affix my signature;
REX E. CALLAGHAN.
