vision of a unitary fireplace having novel;

anchoring means for securing the same to a building wall.

A still further object of the invention is to rovide a device which will be relatively 'ght in weight by reason of a shell-like wall formation which provides a chamber, at

either side of the fire compartment, open at the 'top and rear and adapted to contain anchoring elements for securing the. fireplace to the building wall.

The invention further contemplates a unitary fireplace, as set forth, which is neat in appearance, inexpensive of manufacture, and satisfactory in use.

Other objects and advantages will be apparent during the course of the following description. v

In the accompanying drawings, forming a part of this specification, and in which like reference characters are employed to designate like parts in all views,

Figure 1 is place constructed in accordance with this invention;

Figure 2 is a fragmentary horizontal sec tional view taken on the line 2-2 of Figure 1 and showing one of the anchoring means for the fireplace and the containing chamber therefor;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4: is an elevation of a reinforcing unit incorporated in the structure; and v Figure 5 is a detailed perspective view showing a fireplace wall portion and a novel staple-like element embedded therein for em gagement by cures the fireplace to the building wall.

Asshown, the unitary fireplace com uses a relatively light shell-like body of p astic walls 5 and a front material inclu ing end medial arched openwall 6, provided with a a perspective view of a fire of the archway.

the anchoring device which sesuitable tiled or other hearth 8 is provided as illustrated. A part of the top 8 of the fire compartment is shown in Flgure' 2.

In producing the structure a mold (not shown is employed and it is preferably forme to give the exterior surface of the walls a brick-like appearance as depictedin Figure 1.

Figure 1 shows that the exterior surface of the front wall is pebbled'or otherwise ornamented with particles, as at b, a layer of such being first introduced into the mold. Referring to Figure 2 it is seen that the walls 5, 6 comprise an outer primary layer a of a sand and cement mixture, in the inner surface of which is embedded a section of metal lath 9. Upon the metal lath 9 is disposed the inner layer d of cinder concrete which completes the wall structure. The metal lath section 9 is shaped in front eleva tion (Figure 3) to conform to the outline of the front wall 6 and is U-shaped as viewed in plan, as suggested in Figure 2, having rearwardly extending legs 9 at each side. Thus, the one metal lath section serves for a fireplace unit. The object of the metal lath is to reinforce the structure of-the device and also to provide for an intimate connection between the layers 0 and-d.

As an additional reinforcing means channel bars 10, 11 arev employed and may be carried by the inner surface of the lath section 9 as per Figu defines a U and skirts just inside the marginal side and top edges of the front wall of the lath section 9 as illustrated. Channel bars 11 two in number, are disposed in horizontally spaced relationship above the archway to reinforce the structure of the fireplace unit at this point it being noted that their ends extend well i) eyond the sides If not carried by the lath unit 9, channel bars 10, 11 are layed in place thereon preparatory to pouring the cinder concrete into the mold.

7 While the layers 0 and d of plastic material are. still soft, staple-like elements .12 are inserted through the inner front wall layer d, one at either side of the arch, so that one of their laterally bent inner ends 12 seats in one of the channel bars 11 against its rear re 3. Channel bar 10.

' wall 17 whereby to hold the fireplace unit firmly in position. i

The open top of the fireplace 1S close'dby a removable mantel piece 18. Whenthis is taken oil? the turnbuckles 14 can be conveniently manipulated without necessitating taking out the fire brick 8 at the side of the fire compartment 8 or cutting through the side wall of the fire compartment in the event that same is also molded. Each anchoring means 12, 13, 14, 15 is therefore housed in a compartment, readily accessible from above by removing the mantel 18,- and also as shown. The same are considerabl removed from the fire compartment wa Is 8.

A fireplace constructed in accordance with my invention is relatively light, strong and durable and can be shipped from place to place as a unit. By the use of this molded construction a wide variety of decorative effects can be produced which would be impossible in a brick fireplace. Furthermore, a fireplace of this kind will notsettle with the chimney. Also in the event that the building has settled the turnbuckles 14 can be adjusted to secure a snug fit again with the adjacent wall.

The cinder concrete d bein very hard and strong, forming a veritablediack bone of the unit and is united with the lighter and more brittle pebble studded layer 0 by the lath section 9. The hardness of the cinder cement assures against chipping with consequent loosening and possible loss of staples 12.

Having thus described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A portable fireplace unit of plastic material comprising spaced opposed walls and a front wall connected thereto, a reinforcing element embedded in said front wall, an adjustable anchoring device sustained by said reinforcing element and protruding from the inner face of the front wall at a point spaced from the inner and outer wall, and said anchoring device being adapted for connection to a building Wall for anchoring the unit thereto.

I 2. A portable fireplace unit of plastic material comprising front and end walls, a reinforcing element embedded in said front wall, an adjustable anchoring device sustained by said reinforcing element and protrading from the inner face of the front wall, andsaid anchoring device being ada ted for connection to a building wall or anchoring the unit thereto.

3. A portable fireplace unit of plastic material comprising front and side walls, the front wall having an opening, a truss bar en'ibcdded in said front wall above said opening and having its ends extending beyond the sides of said opening, looped attaching devices embedded in the inner face of said front wall and laterally bent ends engaged behind said truss bar whereby to sustain said looped attaching devices, and adjustable means secured to said looped attaching devices and adapted for engagement with a building wall for anchoring the fireplace unit thereto. 1

4..A portable fireplace unit comprisinga body portion of plastic material havin front and side walls, the front wall having an opening therein, a reinforcing unit of metal lath coextensive in area with and embedded in said front wall and having laterally turned end portions embedded in said side walls, a U-shaped reinforcing element embedded in said front wall adjacent said metal lath and having its legs adjacent the plane of said end walls and its horizontal intermediate portion adjacent the upper edge of said front wall, a horizontally disposed ed for engagement with an adjacent building wall for anchoring the unit in place.

5. A portable fireplace unit comprising front and side walls, the front wall having an opening; said front. and side walls, comprising an outer layer of ornamentable plastic material and an inner layer of relatively harder and stronger layer of plastic material forming a backbone or reinforcement for said unit; a metal lath section for uniting said layers, a truss bar embedded in said relatively harder layer and disposed above and extending beyond the sides of said front wall opening adjacent said metal lath sectionyand support engaging devices extenfling into said second mentioned layer and haying laterally bent ends sustainingly engaed by said truss member whereby to preve t said support engaging devices from pulling out.

In testimony whereof I aflix m signature.
