SIDE ARCH BRICK.
Original No. 1,487,146, dated March 18, 1924, Serial No. 626,902, filed March-22, 1923. Application for freissue filed August 20,
. My invention aims to provide an improved side arch and brick therefor particularly adapted for use in locomotive fire boxes.
In the drawings, wherein. I have shown an illustrative embodiment of my invention:
Fig. 1 is a view partly in section showing a port-ion of a locomotive fire box equipped with an arch embodying my improved side Fig. 2 is a fragmentary cross sectional view of the arch taken on the line2-2 of Fig. 1; v
Fig. 3 is a. fragmentary cross sectional View taken on the line 33 of Fig. 1, drawn to a larger scale;
Fig.4 is a fragmentary top plan View, partly in cross section, of a portion of the arch shown in Fig. 1; I
, Fig. 5is a detailedl view partly in cross section, showing a supporting lug and washer designed for supporting the outer edge of the side archbric-ks; I
. Figs. 6 and 7 are perspective views taken from different angles of the form of arch bricks illustrated in Figs'l to 4; I
Fig. 8 is a perspective view ofone form of center arch brick suitable for use with my side arch bricks; and,
Fig. 9 is a perspective'vlew taken from one end of one of my side arch bricks.
Referring more in detail to the'drawings, Ihave the-re shown aconventional locomotive fire box presenting side sheets 1, and a plurality of arch tubes 2 for supporting my improved arch bricks which rest at one sideon the side arch tubes and at the other side in contact with or closely adjacent to the side sheets so that the bricks bridge the i 3 space between the side sheets and the side arch tubes.
Herein I have shown a plurality of lugs 3 (see Fig. 5), one for each brick, and these lugs are preferably welded to the side sheets in a plane containing the axes of the tubes. Before they are applied. they are preferably pointed or cone-shaped? as at 4 and buttwclded to the side sheets by means of what is commonly known as a fillet electrical weld.
Herein I have shown means to protect the supporting lugs against the action of the radiant heat in the fire box and also to provide adequate supporting-surfaces for my bricks. To these ends I have shown oblong 1925. Serial NO. 51,531.
perforation 6 to receive the lug, and these washers are conveniently made of athickness equal to the length of the lugs.
As illustrated, herein my improved side bricks are generally rectangular in form and have arcuate body portions 7 of approxiinately uniform thickness which are curved substantially throughout their width on the upper and lower surfaces. whereby to present flame channels'between the side sheets and the side arch tubes (Figf 2). This shape the side sheet edges are relatively wide and fiat being approximately at right angles to the body portions of the bricks and arranged to hug closely against the side sheets throughout their areas. These thick side edges have provision for supporting them on the lugs 3, while the opposite sides are undercut forming channels or grooves 9 to fit against the side arch tubes and normally wedge them toward the side sheets.
At the thickened sides of each of the bricks I provide a recess 10, preferably midway of its length, adapted to receive the washer 5. This recess has a shoulder at its upper side to support the weight of the brick on theflupper surface of the washer. This provides for distributing the weight of the brick over amuch larger surface than the lugs present and prevents breakage incident to shocks and jars of thelocomotive. As illustrated, the recess 10 is arranged between the upper and lower edges of the brick more adequately to protect the lugs and washers from the action of the radiant heat in the fire box.
Referring to Figs. 6 and 9 I have there shown the tube engaging sides of my bricks as being arcuate throughout; that is, the tube engaging channels 9 are not only curvedin cross section to correspond with the curvature of the tubes but are also curved through out their lengths and the edges of the bricks above the undercut channels are correspond- V proper position on the side. sheets an ingly curved so as to permit the bricks to adapt themselves to bent tubes and be supported thereon atone ioint. Moreover, th1s shape permits one side rick to be used either as a leftlor as a right'in that portion of the locomotive. fire box wherein the side arch tubes are not in parallelism with the side sheets.
shaped bricks, one for a right and the other for a left.
I have here shown center arch bricks 11 which are similar, in some respects, to those shown in my prior patent dated August 13, 1918, No. 1,275,386; but my improved side arch bricks are adapted for use with'many other forms of center arch bricks, and Vice versa. a
The installation of my improved side bricks in an ordinary locomotive fire box simply calls for the welding of the ln 1in t 1e rovision of suitable washers to support the bricks in the same horizontal plane as are the center arch bricks sothat there will be no tendency for them to wedge against the tubes out oftheir proper position. They are placed with their end edges in contactso that one helps to sup ort the other against rocking movement a ter the adapt themselves to the tubes with t eir thickened straight side edges either contacting with the side sheets 1 or lying closely adjacent thereto. Thus it is apparent that an arch embodying my invention may quickly and readily be installed and replacements orre pairs may easily be made. is
Obviously, my invention is susceptible of various changes to adapt it to difierent types of fire boxes.
Having thus described my invention, what I claim and desire to secure by Letters Pat? ent is:
,1. A side brick for locomotive arches,
curved throughout its upper surface and Thus, corresponding right and left side bricks'may be made identical to avoid the necessity for making two specially side of the brick being undercut to form a supportin ledge.
' 2. A si e brick for locomotivearches, one side. of the brick being provided with a downwardly extendin flan e which flan e is substantially at rig twang es to the b0 y of the brick, thereby forming a flat side, the
depth of which is greater thanthe' mean 3. A side brick" for locomotive arches,
curved throughout its uppersurfa'ce and provided with a downwar on its one side, the depth of the flange being greater than the mean thickness of the body portion of the brick, and the lower surface of the brick being arcuate and merging into said flange, the said flange being provided on its outer surface with a depression for the reception of the supporting means, and the said flange being'arran'ged perpendicularly with the body of the brick, the oppositeside of the brick having an undercut portion extending throughout its length to form a supporting ledge. J
4. In combination with a locomotive side sheet having lugs welded thereon, washers fitting over said lugs, a plurality of arch tubes, arcuate side bricks, said bricks having a perpendicularly arranged flange at their one side, the depth of which is greater than side sheet, and presenting an under-cut tube engaging channel atgthe other side to conform tot-he curvatureof thetube, said channelled side being curved from one end edge ly depending flange of the brick to the other whereby said brick may be used interchangeably at the right or or left hand side of the arch and be supported in a substantially horizontal position.
In testimony whereof, I have signed my name to this specification.
EDWARD M. CARROLL.
