ments in Molds; and I do hereby declare that 'the following is a full, clear, and exact description of the invention, such as 'will enable others skilled in the art to which it appertains to make and use the same.
. My invention relates to improvements in molds employed in the construction ofconcrete walls and structures, and it consists in the constructions, combinations and arrangements herein-described and claimed.
An object of my invention is to provide a simple and durable form of mold comprising .a plurality of mold plates adapted to be conveniently assembled to provide continuous molding faces of any required sizes or dimensions for meeting all conditions arising in practice.
A further object of my invention is to provide an inexpensivemold, which can be employed with a minimum amount of labor for constructing the different types of concrete structures A further object of my invention is to provide an improved mold comprising universal platesadapted to be rigidly locked together for providing continuous mold faces of any required dimensions; the universal mold lates being so constructed that a common ocking means can be employed for locking any one of said lates to any other thereof. Referring to tiie drawings forming a part of this application and in which similar reference symbols indicate corresponding parts in the several views :Figure 1 s a fragmentary perspective view, illustrating one embodiment of my invention as employed in progressively building up monolithic crib work,
or other structures; Fig. 2 is a detail sectional elevation on the line 2'2 of Fig. 1 Fig. 3 is a detail sectional view through a hollow concrete wall, illustratin my mold applied to theprogressively bui ding up of said wall;
' Fig. 4 1s a perspective view of several mold law secured together by a slightly modied'form of locldng means; and Fig. 5 isa plan view of the locking means shown in Fig. 4.. 1 and 2 illustrate oneuse of my inventl for progressively building up a mono-' lithic stnucture, such as a crib work. In this operation, a suitable foundation, such as a bed of concrete, is prepared.
A- plurality of suitable mold plates 1 are placed on the found ation and secured together to provides continuous molding face for the outer surface of the desired structure. mold lates 1 have braces3 secured along their rear aces; said braces terminating a slight The distance from the ends of the mold plates and l being provided with recesses for shdingly receiving thelock lates 2.
--Where the mo d plates 1 are arranged at an angle to provide a. corner to the superstructure, I employ a lock plate 2 formed at an angle corresponding to that of the desired corner in the structure, as shown in Fig. 1. It will be noted that each of the lock plates 2 extends across the joint between the abutting mold platesand is maintained in close engagement with the rear faces of said plates; thereby constituting a rigid backing extending across the joints between the abutting plates and insuring 'regularity in the continuous molding face formed by the several mold plates.
Suitable mold plates 4-and 5 are set on the foundation and secured together to provide the required molding faces for the desired inner surfaces of the structure. The plates 4 are provided with braces 6 corresponding to the braces 3 of the plates 1. The mold plates 5 are provided with resilient curved ends arranged to engage lock plates 7 inserted in the recesses of the braces 6. Braces 8 are shown on the rear faces of the plates 5, but such braces extend only to the curved portions of theplates and are not provided with recesses. The various sections of mold plates thus assembled on the foundation are spaced apart in the desired manner by sleeves 9 of the required length, which extend between and engage the mold faces of adjacent sections. The mold sections and sleeves are securely clamped to gether by bolts 10 extending through said sleeves and arranged with the bolt head and nut engaging the rear faces of corresponding mold sections; This provides a very advantageous construction, since by the use of sleeves 9 of various lengths, the mold sections can be convenientlyclampcd rigidly together with any desired spacing. The
sleeves'9 can advantageously be formed of paper, or tar paper, but they can be formedand handling of the mold plates.
'tortion thereof. then withdrawn, and the lock plates dein lany manner, preferably of porous materia.
The mold plates are shown formed of metal face plates provided with openings 11 for the insertion of the clamping bolts, and having braces riveted, or otherwise secured, on their rear faces. The braces insure proper rigidity to the face plates and provide means for engaging the locking plates.
The mold plate indicated by numeral 5 is a tached for permitting convenient removal The spacing sleeves 9 remain in the walls of the structure and permit ready withdrawal of the clamping bolts 10; said spacing sleeves can be suitably filled up or plugged, as by a- .filling of concrete or other suitable material.
The mold plates are then again assembled and positioned to bring the lower series of bolt openings in the mold lates into registry with the upper serieso s acing sleeves previously molded into the wal s of the struc ture. Spacing bolts 10 are then inserted through such registering bolt openings and sleeves, and the bolt nuts screwed down to securely clamp the mold sections to the previously formed ortions of the walls. In this position of t e parts, the mold sections will extend above the walls to provide molding faces for the further progressive building of said walls, asshown in Fi 1. Clamping bolts 10 are inserted throng the upper series of bolt holes in the mold plates and through suitable spacing sleeves 9 inter-.
posed therebetween, for rigidly clamping the several mold sections together. The space between the several mold sections is t en filled in with concrete, and the above steps repeated until the walls of the structure have been progressively built to the re uired dimensions. a
t will be obvious that a plurality of mold plates can be locked together for providing a molding face having any desired length and breadth. Thus, by employing loclcing plates of necessary length, one or more series of mold plates could be assembled to rovide a continuousmolding face with the p ates 1,
and the several series of mold plates rigidly locked together by the common locking plates 2.
Fig. 4 shows a locking plate having a length equal to twice thewidth oi a mold especially in Fig. 2.
sveaoo plate, and constituting a common locking means for the abutting edges of four mold lates. Core blocks 12 are rovided for forming any desired openings or recesses in the. walls of the structure. The core blocks can be constructed in any suitable manner, and are provided with bolt open' 14 to ermit insertion of the bolts tlthroug 1 for rigidly clamping the core blocks in position with the mold sections, shown core blocks are shown in position for receivingconorete above their upper portions, and the previously formed openings 13 in the Walls of the structure are shown with the core blocks removed therefrom.
In Fig. 1, two of the Fig; 3 illustrates one embodiment of my invention for progressively building up hollow walls. In this construction, a core block 15 is suitably s aced from the mold sections 16 by spacing s eeves 17. The sleeves 17 are similar to the previously described spacing sleeves, and remain in the concrete walls upon removal of the clamping bolts, cores and mold sections. The openings'formed in the walls by the spacing sleeves 17 can be closed with concrete, and tie bolts can be inserted in any desired part of said openin The two portions of the hollow wall can oe rigidly bound together with solid concrete at any desired portions by omitting the core block 15 and suitably spacing the mold section 16 by spacing sleeves 17 eiitending therebetween a shield of sheet metal, or other material, being placed on top of the wall portions to bridge the space thercbetween and prevent entrance of the concrete.
Figs. 4 and 5. illustrate a slight modification,-in which the braces 18 on the rear faces of the mold plates 19 are provided with inclined recesses 20 the locking plate 21 being formed with oppositely tapered portions 22 for engaging the corresponding recesses in the braces of abutting mold plates. This construction strongly forces together the abutting edges of the mold plates and insures the maintenance of regularity and smoothness in the continuous molding face provided by the several mold plates.
I have illustrated and described preferred and satisfactory constructions, but, obv1 ously, changes could be made within the spirit and scope of my invention.
Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is:
1. A snap mold for concrete, comprising inde endent mold plates adapted to be as- 'sern led to constitute mold sections fol-providing continuous molding faces of any required dimensions, braces carried on the backs of said mold plates and provided with end recesses, locking plates -fitting such recesses for looking together the abutting mold plates of said sections, and adjustable clamping means for clamping together said mold sections with any desired space between their molding feces, substantially as described.
2. A snap mold for concrete, comprising inde enden't mold plates adopted to be as sem led to constitute mold sections for providing continuous molding faces otsny required dimensions, braces carried on the backs of seid mold plates and provided with end recesses, locking pistes fitting; such recesses for locking together the abutting mold plates of said sections, said locking plates constituting rigid beckings extending across the joints between said-til: ntting mold plates, and adjustable clamping means for ehn'nping ogether said sections with any desired s was ietween their molding feces, substantially as described.
3. A snap mold for concrete, comprising I i I 1 g i i l l I independent mold plates adapted to be its sembled to constitute mold s :ti0ns for pro; viding continuous llmldillg feces of any required dimensions, braces carried on ;the backs of said mold plates and provided with inclined recesses, looking, plates Formed with oppositely tapered portions for engaging such inclined recesses to lock together the abutting mold plates of said sections and.
strongly forcing together the abutting edges of said plates, and adjustable clamping means for clznnping together said sections with any desired space between their moldin feces, substantially described.
