FORM FOR POURING AND METHOD FOR FACING.

Application filed February 21, 1927. Serial No. 169,766.

My invention relates to a new and useful improvement in a form for pouring and a method for facing concrete structures, and is adapted particularly for use in the fabrication of portable fire places. These portable fire places which are now becoming uite well-known commercially are generally ormed from concrete with a facing having a special desi 11 formed therein generally to simulate lai brick and the like. In constructing these fire places the front face is generally provided with an artistic finish, either in color or in inlaid material, such as crushed granite, and the like. The side faces, however, which are also exposed to view when the fire place is mounted in a room are not finished because of the impracticability of placing a finished surface on the side faces.

The present invention provides a method for facing-not onl the front face of the structure but the side faces as well, so that all sides of the structure which are exposed view present a finished appearance.

It is another object. of the invention to provide a form whereby this'finishing of the nde faces, as well as the front face, may be affected.

Another object of the invention is the provision of a form whereby the side faces nay be poured in section, and these sections lmalgamated with the front face to provide t unitary structure having all of the fac s inished.

Another object of the invention is the prorision of a form consisting of the essentials If the detail of structure shown.

1 Other objects will appear hereinafter.

The present invention consists in the com- )ination and arrangement of parts hereinlfter described and claimed.

The invention will be best understood by drawings L reference to the accompanyirkg cation, and

vhich form a part of this speci n which Fig. 1 is a perspective view of the finished tructure.

Fi 4fis a sectional view taken on subtantlally line 4-4 of Fig. 3.

Fig. 6 is an enlarged new of thcend sec,- ion in Fig.2.

ing 21 an 6 is a fragmentary top plan view As shown in the drawings I provide a frame ll'supported by legs 12, and positioned across the frame 11 are supports 13 upon which a table bed 14 is positioned. T is table bed has a plurality of rails 15 projecting upwardly therefrom, these rails elng so arranged as to form on the concrete which is poured thereagainst the design of the fire place, as shown in Fig. 1. When pouring the structure, alayer of sand 16 is first poured on the bed 14, this layer of sand 16 being covered with a layer 17 of crushed stone, colored mortar, or the like, depending -upon the nature of the facin which it is desired to give to the finishe structure. As shown in Fig. 1, the fire place, when completed, comprises a front wall 18, and side. walls 19 and 20, the front Well being (provided with the hearth openhaving the arch 22 formed therein. i To form the arch I have provided end rails 23 and 24 which connect to the truss or arch support 25. Placed over the end rails 24 and 25, and spanning the arch, is a spacing rail 26, projecting downwardly from the inner surface of which is a rail 27 engaging the inner edges of the vend rails 23 and 24. A wing nut 41 is threaded on a bolt 42 which projects upwardly from the bed 14 so as to clam the rail 26 in engagement with the mem ers 23 and 24. A similar spacing member' 28 is clamped in the rails 23 and 24 ad.- jacent their endsby means of the wing nut 43 which is threaded on the bolt 43 which projects upwardly from the bed 14. Secured to the bed 14 is a base forming board 29, the member 33 forming a continuance thereof, so as to rovide with the end members 35 and the rails 37 and 38a frame for determining the size of the front wall 18. An abutment block 35 is mounted on the member 33 and an abutment blockv 36 is mounted on the member 37 The member 38 is held in posi tion by means of a clamping block 38' through which extends the bolt 39 provided with a wing nut 40, the". arrangement being i such that this clamping block 38 may be tightened to hold the rails 38 in position. Mounted fixedly upon the bed 14 and projecting u wardly t erefrom at the four corners of t e bed are end boards 30, and pro- .the end board 30. Mounted on the inner face of each of these end boards 30 is a supporting block 44 upon which rests the ends of an angle iron 46 which is secured to spacing blocks 45 mounted upon the inner end gate 47 The inner end gate is adapted to engage between spacing blocks 48 which are carried by the members 33 and 37. (See Fig. 2 and Fig. 3.) An outer end gate 49 is provided which carries a transversely extending angle iron 50, a plurality of vertically extending angle irons 51 being also mounted on the outer side of the outer end gate. Mounted on the lower edge of the outer end 'ate'49 is an L-shaped stri of metal 53 which extends the full lengt of the frame, this stripbeing secured to the end gate by means of,

a screw or in any other suitable manner. (See Fig. 5.) This outer end gate is adapted for engaging between blocks 54 and 55 which are mounted on the inner surface of the members 33 and 37. Hooks 57 are mounted on the extensions 31 and serve to engage inopenings formed in the angle iron 50 so as to. securely lock the .corner plates 30 in engagement with the edges of the end gate 49. This outer end gate 49 is provided with the upwardly extending ribs 15 which serve tfo outline the pattern on the finished end ace.

laid in horizontal position, and a layer of sand 16 poured thereon, this layer of sand 16 being a thin one, as shown in Fig. 5, so

that the pattern forming ribs 15 will project thereabove. The layer of sand is then covered by a layer 17 of facing material, such as crushed rock or the like, and this is in turn followed by a layer 58 of concrete. There is then placed over the concrete a binding plate 59. This plate, together with the outer end gate 49 serves to clamp the plastic material contained between them in position so that when the end gate, together with the plate 59, are raised to vertical position, a flowing of the plastic material would be prevented. In order to effect this clamping of the endgate and the plate 59, I have provided a clamp comprising a leg 60.

through which is projected a bolt 61. A cooperating leg 62 is provided through which the bolt 61 projects, a wing nut 63 being threaded on the bolt 61. A spacing block 64 In operation theend gate 49 would bethe angle iron 50, the block 67 will also gage the upper face of the outer end gate When these clamping members which n be used in any desired numbers dependi upon the size of the structure to be pom are placed in position, as shown in Fig. the wing nut 63 is threaded to effect a clan ing of the parts between the legs and On account of the shape of the block 6 secure clamping of the legs throughout tb length is etl'ected. After the clamping 1 been completed, the outer end gate 49 raised into vertical osition, and moan between the corner p ates, as shown in F 3. The inner end gate 47 is then placed position, and it will be noted that the in:

end gate 47 is supported by the angle iron in such a manner as to terminate above bed 14, leaving the space 56 formed then The layer of sand 16 is then poured over bed 14, followed by the layer of facing r terial 17. A layer of concrete 68 is tl poured over the facing layer 17, after wh a wire screen 69'is positioned on the 1a of concrete 68, this layer of concrete be reinforced or not, as desired. The space lying between the lower endof the inner t gate 47 and the screen 69 is then filled w a strip 70 of concrete possessing a high 11 centage of cement so that it will quickly gin to set, and serve as a filler to prevent plastic material poured into the space tween the inner surface of the inner gate 47 and the plate 59 from passin o wardly below the lower edge of the end g 47. Afterthe cement layer 58 has set t certain degree the space between the in surface of the inner end gate 47 and plate 59 is filled with concrete, L-shaped inforcing rods 71 being first placed alc the ends 19 and 20, as shown in Fi". 5, number of these reinforcing rods being s stantially the same as the number of clamping members 60, and lying in enga ment therewith, so that the legs 60 serve support the members 71 in upright siti When this concrete has set sufficient y to tain the layer 58 in its position, the clampi legs 60 and 62 areremoved, as is likew the plate 59 and the L-shaped member so that the layer 58 will amalgamate w the rest of the concrete forming the s members. A layer 72. of concrete is tl poured over the wire mesh 69 and this la] 72 will amalgamate with the filler 70, 1 pouring being sufiieiently close together permit the amalgamation of the vari: pour ngs, so that a unitary structure will provided. An abutment block 73 is mou ed on the bed 55 to engage a wedge 74 wh? is driven into engagement with the on end gates to retain them in position. (5 Fig. 3 and Fig. 2.) After the concrete 1 set so as to retain the form indicated 1 end gates are removed, after which the or crete fire place may be removed from the form.

It is believed evident that a finishing of the end faces as well as the front face becomes possible in this manner without in any Having thus described my invention what I claim as new and desire to secure byLetters Patent is:

1. The method of pouring a. fireplace formed from plastic material with facing on a plurality of sides thereof consisting in pouring the sides separately with the facing thereon and mounting the sides in co-operative relation and causing the plastic material of the abutting edges of the sides to amalgamate.

'2. The method of forming a structure of" plastic material having a p rality of sides provided with a facing consisting in forming the sides separately and abutting the sides together while the plastic material is in a plastic state and permitting the material to harden while said edges are in abutment, the edges to amalgamate together to form a unitar structure.

3. T e method of forming a structure fro plastic material having a plurality of sides provided with a facing consisting in pouring a portion of said sides with the facin thereon while in a horizontal plane and a utting the sides to ether in co-opera tive relation while the said portion is in a plastic state, and then pouring the remainder of said sides and permitting the amalgamation of the plastic material of the abutting edges of said s1 es.

4. The method of forming a structure from plastic material having a plurality of sides provided with a facing consisting in pouring a portion of said sides with the facing thereon abutting the joining edges of sald sides together and finishing the pouring ofthe same permitting the lastic material of adjacent edges to ama gamate and retaining the facing in position until said plastic material sets.

5. The method of forming a structure from plastic material adapted to set and harden, the side faces of said structure having a facing thereon consisting in: pouring .a portion of said sides with the facing thereon, clamping said pourin in a form to retain said facing 1n position; a utting the edges of the forms together, pouring the remainder of said sides and removing said clamping means and permitting said abutting edges to amalgamate and set as a unitary structure.

6. -A form for providing a facing on a plastic structure comprising a side wall; an intermediate clampin wall; means for clamping said interme iate wall in position; a second'end wall; means for clamping said second end wall in position; and means for releasing said intermediate wall andpermitting its removal therefrom without disturbing plastic material poured between said end walls.
