MOLD FOR CONCRETE STRUCTURES.
SPECIFICATION forming part of Letters Patent No. 699,625, dated May 6, 1902. Application filed November 14, 1901. Serial No. 82,279- (No model.)
To (tZZ whom it 77mg concern:
Be it known that I, CHARLES F. LANCAS- TER, a citizen of the United States, residing at Petoskey, in the county of Emmet and State of Michigan, have invented certain new and useful Improvements in Molds for Concrete Structures; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.
Theinvention relates to molds for concrete 7 structures.
In building walls and other structures of concrete the material is confined and kept in form by the mold until set.
The object of my invention is to provide a mold for this purpose which shall be simple of construction,durable in use, comparatively inexpensive of production, and capable of being removed at intervals as the structure advances and being again employed for continuing the work.
l/Vith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims.
In the accompanying drawings, Figure 1 is a perspective view illustrating the application of my invention. Fig. 2 is a top plan View showing the corner and end sections of the mold in position. Fig. 3 is an end view of the side pieces of the mold, showing the manner of operating the same. Fig. at is an end view of the corner-sections of the mold, illustrating the manner of operating the same; and Fig. 5 is an end view of one of the end pieces of the mold.
Referring to the drawings, 1 represents a wall of a building in the course of construction, said wall being provided with an intervening air-space. The mold for forming a wallol this construction consistsof the outer side pieces 2 and 3 and the inner side pieces 1 and5 of proper length and height. To the side pieces 2 and 3 are fixed posts or standards 6 and 7 respectively, and to the side pieces 4 and 5 are fixed posts or standards 8 and 9, respectively. The upper ends of the posts or standards 8 and 9 are fixed to a crossbar 10, and the upper ends of the posts 6 and 7 are pivoted to said cross-bar. As shown in Fig. 1, these posts are illustrated in duplicate or are in two sets, each set being similarly connected to its cross-bar. 11 denoteslevers pivoted at their lower ends to said cross-bar, and 12 denotes a handle connecting theupper ends of said levers.
13 denotes links pivoted to the posts 7 and to the levers 11, and M denotes similar links pivoted to the posts 6 and to the levers 11.
This completes the description of the parts forming'that part of the model to be used for building the side walls of a concrete structure, and the operation is as follows: In the position illustrated in full lines in Fig. 3 the sides of the mold are shown in position to receive the plastic mass to form the structure. This mass is filled in between the sides 2 and A and and 5, and after it has remained a suitable period and becomes sufficiently set the levers 11 are rocked to the position shown in dotted lines in Fig. 3, which frees the side pieces from the two sections constituting the wall and permits of the mold-sections being moved longitudinally to form a continuation of the wall in that direction or moved vertically, as the case may be, and in either be clamped to the set sections of the wall in position to receive a fresh charge of plastic composition.
15 denotes the end piece of the mold, which in height corresponds to the height of the side pieces and in length suflicient to reach across from the ends of the side pieces 2 and 5 and is provided with lugs 16, in which is loosely journaled a shaft 17, to the endof which are loosely secured hooks 18, which are adapted to engage lugs 19, projecting from the ends of the side pieces 2 and 5.' A bailshaped lever 20 is journaled upon the rod 17 and is provided with beads 21, .which are adapted to engage the end piece of the mold and when pressed downward force said end piece firmly against the ends of the mold- sections 2, 3, 4, and 5 and lock said end piece in proper position, the bearings 16 permitting of a sliding movement of the shaft 17 therein.
In molding a corner the side pieces 3 and 4 of the mold are shortened, the side pieces 4 being slightly shorter than the side piece 3, as shown in Fig. 2. The corner-mold consists of mold- boards 22 and 23, secured to angular posts or standards 2i and 25, which are pivoted to a cross-bar 26 and have their inner horizontal projecting ends extending close toward each other, as shown more clearly in Fig. 4. The adjacent ends of these horizontal extensions are provided with recesses 27 for a purpose hereinafter to appear.
28 denotes a lever pivoted to the cross-bar 26 and provided with acrank- pin 29, and 30 denotes a bar having a laterally-extending head 31, which projects downwardly and between the horizontal ends of the standards and into the recesses 27. By rocking this lever 28 it is evident that the boards or side pieces 22 and 23 of the mold will be moved from the position shown in full lines to the position shown in dotted lines, whereby it may be freed from the wall of the structure when said wall is set. The cross-piece 26 is provided at one end with a hook or other fastening means 32, which is adapted to hook over the cross-piece 10 of the mold, as shown in Fig. 2, in placing the corner-mold in position to receive its charge of material.
From the foregoing description, taken in connection with the accompanying drawings,
the construction, mode of operation, and advantages of my invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from the spirit orsacrificing any of the advantages thereof. For instance, instead of using four sides to form two spaced-apart Wall-sections I may employ but two sides, in which event but one wall section will be formed.
Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-
nation with the side pieces, a cross-bar and posts or standards secured to the side pieces, one fixedly connected at its upper end to the cross-bar and the other pivotally connected to said cross-bar, of means for moving one side piece toward and away from the other, said meansv comprising a lever pivoted to the cross-bar and a link connected to the movable side piece, substantially as set forth.
2. In a mold for concrete Work, the combination with an inner set of side pieces and an outer set of side pieces, posts or standards secured to said sets of side pieces, cross-bars to which the upper ends of the posts of one set of side pieces are fixed and the upper ends of the posts of the other set of side pieces are pivoted, of levers pivoted to said cross-bars and links pivoted to said levers and to the movable sets of side pieces, substantially as set forth.
3. In a mold for concrete work, the combination with an inner set of side pieces and an outer set of side pieces, posts or standards secured to said sets of side pieces, cross-bars to which the upper ends of the posts of one set of side pieces are fixed and the upper ends of the posts of the otherset of side pieces .are pivoted, of levers pivoted to said crossbars, links pivoted to said levers and to the movable sets of side pieces, and a handle connecting said levers, substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
