SPACER-BLOCK FOR REFRACTORY ARGHES,
To all whom it may concern:
Be it known that I, ALFRED H. WILLETT, a citizen of the United States, residing at West New ,York, in the county of Hudson and State of New Jersey, have invented certain new and useful I'mprovements in Spacer-Blocks for Refractory Arches, of which the following is a specification.
This invention has reference to the ,provision of an improved form of spacer block .or brick for use in connection with refractory arches such as are commonly employed in fire boxes of boilers or locomotives, and the first of the objects thereof is the provision of a spacer block of the type indicated which will be adaptable not only to various boiler and fire box constructlons, but also to differences in the width of the openings required between the refractory arch and the flue sheet to suit difl'erent grades of fuel. Another object of the present invention is the provision of a block of the character specified which will be of such characteristics that it will permit of the use of the same block in either single, double or multiple relations to' meet different conditions of service and eliminate the need of carrying in stock a large number of blocks of different dimensions and shapes.
The above as well as such other objects as may hereinafter appear, I attain by means of a construction which I have illustrated in preferred form in the accompanying drawings wherein: a
igure 1 is a longitudinal sectional view of a fire box with my improvement ap lied thereto; Fig. 2 is a transverse sectlonal view showing the arch in elevation; Fig. 3 is a partial sectional view showing an arrangement wherein the special spacer blocks are em loyed so as to secure an elevation of the orward edge of the refracto arch and a substantial opening between said forward edge of the arch and the flue sheet; Fig. 4 shows two refractory bricks supported in osition upon one of the special blocks; supporting block shown in Fig. 4; Fi 6 is a sectional view showing the forwar ed e of a refractory arch spaced away from t e flue sheet by the use of a single spacing block such as in normal service would give, approximately a three inch opening between the front edge of the refractory arch tively show the use of ig. 5 is a plan view of the special Specification of Letters Patent. Patented 11 15, 1920, Application filed April 24, 1919. Serial No. 292,379.
and the flue sheet; Figs. 7, 8 and 9 respectwo, three and four spacer blocks to secure other variations of openings; and Fig. 10 is a fragmentary plan view of the forward portion of the fire box illustrating the spaced relation of the arch with respect to the flue sheet.
Referring now more particularly to Figs. 4 and 5 it will be seen that in carrying out my invention I provide a block having a curved recess 1 on its under face and a correspondingly curved upper surface 2, a projecting rib 3 on one side, and a corresponding recess 4 on the other side opposite said ri 3.
The rib 3 is of such dimension that it will fit between the ends of the bricks of the refractory arch shown at 5 and 6 in Fig. 4.
It will be understood that in carrying out my invention the particular arran ement or disposition of the arch s'uppor'tm tubes 7 is not material as my improved pm of spacer block is obviously applicable in any place where a refractory arch is to be supported. y
. In Fig. 10 I have shownthe arch'spaced away from the flue sheet 11 by means of two spacer blocks on each tube.
I claim: H
1. In brick arch constructions for locomotive fire boxes provided'with arch tubes and a flue sheet, blocks adapted to space the arch away from the flue sheet, each of said blocks having a curved underor tube engaging surface and a similarly curved upper surface, the tube engaging surface being a flue sheet, blocks adapted to space the arch away from the flue sheet, each of said blocks ha'vin c substantially parallel forward and back faces adapted to engage faces of other blocks where two or more are arrange together to secure varying spaces between the arch and the flue sheet, and said forward and back faces provided with complementary interlocking means. i
8. In brick arch constructions for locomotive fire boxes provided with arch tubes and a flue sheet, blocks adapted to space the arch away from the flue sheet, each of said blocks having a tube engaging surface on one face and a supporting surface on its opposite face constructed to correspond with said tube engaging surface whereby to permit the mounting of one of said blocks upon another or of a brick of the arch upon a block.
4:. In brick arch constructions for locomotive fire boxes provided with arch tubes and a flue sheet, blocks adapted to space the arch away from the flue sheet, each of said blocks having a tube engaging surface, substantially parallel inter-engaging forward and back faces provided respectively with a groove and with a projecting rib, said rib adapted to fit between bricks of the arch.
5. In brick arch constructions for locomotive fire boxes provided with arch tubes and a flue sheet, a block adapted to space the arch away from the flue sheet, said block having a tube engaging surface, an arch engaging surface, and a projection on the arch engaging surface adapted to fit between bricks of the arch.
6. In brick arch constructions for locomotive fire boxes provided with arch tubes and a flue sheet, a means for securing a varying spaced relation between the flue sheet and the arch comprising tube supported spacing blocks adapted to be arranged singly or in a series upon each tube between the arch and the flue sheet, substantially parallel inter-engaging forward and back faces on each block, and complementary interlocking recesses and projections on the substantially parallel faces of the blocks, the projections on the blocks adjacent the arch being adapted to extend between bricks of the arch.
7. In brick arch constructions for locomotive fire boxes provided with arch supporting members and a flue sheet, blocks adapted to space the arch away from the flue sheet, each of said blocks having a support engagin surface on one face and a corresponding supporting'surface on the opposite face, the support engaging surface being adapted to engage either an arch supporting member or the supporting surface of another block, and the supporting surface being adapted to act as a seat for bricks of the arch.
In testimony whereof, I have hereunto signed my name.
ALFRED H. WILLETT.
