MOLD FOR CONCRETE WALLS.

Specification of Letters :Patent Patented Mar.. 29., initd.

Application filed February 26, 1908. Serial No. 417,941..

To all whom 'it may concern:

'Be it known that I, HARRY J. KIMMEL, a citizen of the United States', residing at lVenatchce, in the county of Chelan and State of Washington, have invented new and useful Improvements i'n Molds for Concrete I'Valls, of which the following is a specification. 4

This invention relates to molds for concrete walls, the object of the vinvention being to provide, simple apparatus in the nature of a sectional mold adapted to be added to from time to time as occasionv demands for the purpose ot' extending the molded wall and turning corners or forming otfsets therein, the inold being Inade u p of a series of sections constructed to have an overlapping and interlocking engagement with one another, the said sections being adjustably latter combined with gaging members which serve to hold the mold sections at the proper distance apart to admit of the torination of a wall between them; also permitting the relative adjustment of the mold sections and their angular' disposition with relathe particular shape ot the wall being formed.

vWith the above and other objects in view, the invention consists in the novel lconstruction, combination and arrangement of partsclaimed.

In the accompanying drawings :'ligurc l is an end view ot opposite mold sections, the supjmrting bars thereotl and the means for gaging the distance between the mold' sections; also the means tor adjusting the angularity of said sections. Fig. 2 is an outside or rear elevation of one oi the mold sections7 showing the connection of the supporting bars therewith. Fig. 3 an enlarged detail vertical cross section through the same7 .showing the. connection between the same and one of the bolts which secure the section to the adjacent supporting bar, Fig. 4 is a detaithorizontal section illustrating the overlapping joints between the sections and one ot the clamps. Fig. 5 is a. 'detail horizontal section showing a corner joint between the sections -and the clamping means therefor. Fioj. is a similar view showing the joint at the. inner angle l between contiguous sections.

The manner in which a wall is .formed by the mold of this invention is illustrated in Fig. l in which l designates a partially constructed wall and 2 oppositely located mold sections which it will be` observed are ar- .anged ata distance apart equal to-the thickness of the wall 1, the wall being termed by introducing concrete in a plastic condition between the opposite mold sections il.

The mold sections. as shown in 1 l, are connected to and supported by oppositely arranged mold sujporti bars f3 'which are connected adjusialny to the mold sections by means vherei natter descrihed7 the said bars 3 extending upward a ein able distan .e above the mold sections where t are connected to and braced by ineens et upper and lower gage bars l ando, rcspectively. The upper gage bar is provided with a plurality of rows ot holes i adaptetto receive pins 7 which pass also through holes in the bars 3 and thereby prevent rela tive movement between the upper ends ot' the supporting

bars

3,4 two or more rows of holes heilig provided in order tornialte, allowance for a tine adjustment otl the distance between said slipporting bars. The lower bar is provided for a portion of its length with holes'S correspoinling in arrangen'ient with the holes (S above described and adapted to receive a pin 9 which passes through the adjacent supporting bar 3. The opposite end portion of the bar 5 is provided with a series ot slots or notches 10 which open ont at their upper ends and incline outwardly toward their lower closed ends as seen in Fig. l, the said ,slots being adapted to receive the trunnions or pivot ll ot a cam lever 12 which is arranged just outside of the adjacent supporting bar 3 as shown in Fig. l, and acts as a cam lock between said supportinfc` ba" and the lower gage bar i?. rlhe cam lever l2 is used to ltorce the opposite mold` sections 2 towardv each other and into closed engagement with the portion of the wall which has been coinpleted as illustrated in Fig. l. It will also be observed in Fig. l, that one or both of the bars 3 ,may be swung outward to an angle as indicated by dotted lines to correspondingly position the mold section carried thereby in order to give a 'liare to one or both sides oi. the wall l as also indicated by dotted lines in said figure. It may here be noted that the inner molding faces of the. sections 2 may be either plain or iigured or given any desired ornanientation in order nected a cam lever 1'? adapted to bear to impart a corresponding ornamentation to the adjacent surfaces of the wall under construction.

Each mold section, as shown in Figs. 2

and 3, comprises a face plate 13, and margi-VVV nal frame pieces 14 ot angle iron which' extend along the four edges of the face plate 13 and are riveted or otherwise fastened thereto as shown. Along one end of the plate 13, the angle iron trame piece is set slightly inside of the extreme edge of said plate as shown in Fig. 4, while at the opposite end the angle iron frame piece is made to project a corresponding distance beyond the face plate 13 as also shown inthe same Fig. 4 thus making provision for an overlapping joint between the contiguous ends of two adjoining sections, which are then fastened firmly together by means of a clamp comprising a U-shaped. body 15 to one end of which is connected a. pivoted jaw 16 adapted tobear tiatwise against one ofthe angle irons, while to the opposite end of the clamp body there is pivotally conagainst the opposite angle iron as shown in Fig. 4 to bind the two angle irons closely together and hold the mold sections in rigid relation to each other.

In forming the outer corner of a wall, the. sections are combined as shown in F igf' in which the two sections are shown as meeting at a right angle to each other, one of the angle irons overlapping the extreme edge of the face plate of the adjoining section, while the two sections are held'together by means of a clamp the same as that illustrated in Fig. 4 but having in addition thereto a corner clip 18 embodying a hook 19 which fits around the outer edge of one of the angle irons and a lip 2() at its opposite end which is engaged by the :head of the cani lever 17. .In this way the Outer corner oi the mold is formed and the abiitting mold sections held firmly in engagement with each other. lhe inner .corner of the wall is formed by abutting sections shown disposed at a right angle to each other `as seen in Fig. 6. .ln this case, however, an ade ditional double angle plate 21 is employech the same having 'a rabbcted offset 22 to receive the projecting edge ot' the faceplate of one section, and an inturned iange 23 adapted to engage over the corner ot' the angle iron-of the adjoining section, the double angle plate 21 thus having an overiapping and interlocking engagement with the mold sections.

ln order to provide for the adjustment of j the mold sections upon the mold' supporting g bars 3, each section is provided with arallel slotted or shouldered bars 24 an 25 l extending along the back and lengthwisei thereof as .shown in Figs. 2 and 3, each of said bars being provided with a longitudinal channel 26 sufficiently wide to receive the heads 27 of the bolts 28 which secure th sectiontorthe adjacent mold supper ing/bar 3( IThe outer 'wall of the journal portion of each bar is providedzwith/a longitudinal slot 29 along Which/the body or shank of the bolt 28 is movable for the purpose ,of adjusting the mold supporting bars lengthwise of thesection which they support, as clearly indicated in Fig. 2.

30 designates a bridge plate or washer adapted to straddle a pair of bolts as shown in Fig. 2 which bolts lie at opposite sides of the supporting bar 3 whereby a iirm connection is obtained between each section and the supporting bars thereof, While at the 'same time providing for the relative adjustment of said members.

The adjustment between the mold sections and the supports therefor enables the sections to be set in proper relation to each other and also permits the sections to be set up or down to bring themy to the required elevation.

Having thus described the invent-ion, what is claimed as new, is

- l. ln a molding apparatus, the combina- -tion of oppositely arranged mold sections,

mold supporting barsV connected therewith,

VsetsV of parallel frage bars located at (liderent elevations an having an adjustable connection with such supporting bars above the mold sections, one set of gage bars being provided with transversely Valined notches at one end, and a clamping device consist-ing of a detachable cam leverhavinfrtrunnions projecting from opposite sides Jthereof and adapted to tit Ainto any opposite pair of notches in the notched gage ars and operating against one of the mold supporting bars to crowd the mold sections toward each other.

s 2.V In a molding apparatus, the combination of adjoining angularly disposed corner forming mold sections, angle iron frame pieces extending vertically of the abutting edges ot" the mold sections, a corner clip provided with a hook shaped flange embracing one of the flanges of one of the said trame pieces, and a clamp adapted to engage said corner clip and the adjacent frame piece and hold the adjoining mold sections together, said clamp embodying a U-shaped body and a cam lever.

ln testimony whereof I affix my si gnature in presence of two witnesses.
