Patented Oct. 9, i951 UNITED STATES Iss1 rFics 1 Claim. 1 This invention relates to improvements in shock resistant fireplaces. An object of the invention is to provide an improved construction of shock resistant fireplace which will successfully resist earthquake and road shocks and vibrations and shocks or jars of other types,

Another object of the invention is to provide an improved prefabricated reinforced concrete block shock resistant fireplace which will be readily assembled and bonded together by ring joints between the several blocks which are filled with mortar and rammed until the joints are free of trapped air and are solidly filled with mortar.

A further object of the invention is to provide an improved form and construction of shock resistant fireplace which will be assembled and tied together by ring joints of mortar between the several blocks and by means of metal reinforcing bolts whose inner ends are curved and are embedded in the blocks.

A still further object of the invention is to provide an improved premolded shock resistant fireplace which will be highly efficient in use and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application:

Figure l is a front elevation of the improved shock resistant fireplace.

' Fig. 2 is a sectional view taken on the line 2- 2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved form and construction of shock resistant fireplace generally designated by the reference numeral l and a chimney therefor generally designated by the reference numeral 2.

It will be understood that the improved shock resistant fireplace I and chimneys 2 are built up block by block from precast concrete blocks which may or may not be reinforced as desired.

A foundation or main supporting base 3 is first set in place, and a bed block 4 is disposed thereon, said bed block 4 having an ash dump 5 formed at the forward end,

By referring to Figs. 1, 2 and 3, it W111 be seen that the fireplace block 5 of U-shape form in cross section, is then positioned upon the bed block 4. A metal liner 1 is then positioned within the fireplace block 6, being spaced from the sides and rear wall of said block to provide a surrounding airpassage 8. A transversely extending air passage 9 is formed above the firepla ce opening and is in communication with the air passage 8. This air passage 9 is closed by louvers it] while the oppositely disposed vertical openings to the air passage 8 are closed by the metal grills II and I2 held in position by means of the inverted U-shape front plate is, which in turn is secured by the bolts 14.

The precast head stone I5 is then set upon the top of the fireplace l, and supports a metal damper throat l6 having a flange ll which rests upon the flange [8 on the metal fireplace liner 1. 'Bolts I9 secure the flange member It! to the liner 1, as clearly shown in Fig. 3 of the drawings. A damper plate 20 is pivotally mounted in the throat l5 and is provided with the depending actuating handle 2|. shown embedded in the headstone l5, the same being used to support the front plate l3. The center opening 22 in the headstone I5 is restricted at its lower end to provide for the damper plate 20.

A vertical filling hole 23 is formed through the headstone I5 for receivin mortar 24 which will be rammed by a suitable pestle ram rod (not shown) to fill in and pack the ring joint 25 in the upper edge of the fire lace block 6.

A mantle shelf 26 will be secured to the front top edge of the headstone I5, by means of the hook end bo ts 2! embedded in the headstone I5, said bolts being shown in Fig. 4 of the drawmes.

The chimney 2 will be built up by superimposed chimney blocks 28, which will be provided with op ositely disposed vertical filling holes 29 for filling mortar 24 into the ring joints 3!] in the lower ends of said blocks 28. Sections of fiue lining 3! will be disposed within the central openings through the chimney blocks 28, and annular spacing members 32 may be disposed between adjacent blocks 28. Also the upper ends of the blocks 28 may be dished as at 33 to provide a mortar seal for the joint between adjacent flue linings 3| and blocks 28.

From the foregoing description it will be apparent that the several types of precast blocks will be laid in place and secured by the mortar A hooked end bolt I4 is rin joints to provide an efiicient form of shock resisting fireplace.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

In a shock resistant fireplace construction having a chimney, a bed block, a substantially U-shaped fireplace block having a rear wall and a groove in the upper edge thereof mounted. on

the bed block with the open side of the U-shaped fireplace block disposed forwardly providing the opening for the fireplace, a hollow head stone.

block and head stone.

4 block, superimposed chimney blocks secured together providing a continuation of the chimney, a metal U-shaped fireplace liner disposed within the open side of the U-shaped fireplace block, supported in spaced relation with the rear wall thereof providing a rear hot air passage, and forming with the side walls of the U-shaped fireplace block and said head stone, a transverse hot air passage at the front of the fireplace communicating with the rear passage, and said metal liner extending into the damper throat further bracing the connection between the fireplace CHARLES J.
