BAFFLE FOR `WATERT`UBE 'BOILER Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed March 11, 1908. Serial No. 420,342.

Be it known that I, LEO WOERNER, a citizen ofthe United States, residing at St. Lotus, in the State of Missouri, have invented a certain new and useful Batlle for Watertubes.

One object of my invention `is to so construct the members of .which the battle is formed that the balile will be lighter in weight than those heretofore'in general use,

so as to obviate 'the liability of springing the tubes, and also to so construct the members that any individual member can be readily placed in position or removed without removing the adjacent members. Another object of my invention is to so construct the members that the bafHe may be made to extend throughout the entire length of the tier of tubes and at the same time to properly direct the flow of gases among the tubes.

In the accompanyin drawings which illustrate one form of ba e made in accordance with my invention, together with a portion of water tubeboiler to which the same is applied, Figure 1 is a vertical longitudinal section through the boiler and furnace; Fig. 2 is an enlarged cross section of a portion of the tubes and Fi 3 is a top plan View.

Like marks o reference refer to similar parts in the several viewsin the drawings.

5 represents the front wall, 6 the rear wall and 7 the fire wall vof the furnace.

8 is the fuel chamber and 9 the combustion chamber, the former being situated between the walls 5 and 7 and the latter between the walls 6 and 7.

Resting upon the front and rear walls 5 and 6 are the front and rear water legs 10 and 11respectively, of the boiler. ing between the water legs 10 and 11 are the usual water tubes 12. Applied to the upper and lower tiers of the tubes l2 are the batlles Extendu 1 3. These baffles 13 are each composed of two forms 'of tile members 14 and 15. The tile members 14 are substantially semi-cylindrical in form so as to fit around the tubes 12 in pairs, as best shown in Fig. 2. The lower edges 16 of each pair are in contact, as best shown in this figure, while the u per edges -17 are separated so as to allow of the partial rotation of `one of the membersaround the tube without disturbing the position of the other member. members 14 is provided with a laterally extending rib 18 which is arranged somewhat above the center of the member and extends throughout the entire length of the member. rlhese ribs 1'8 are so proportioned that each 'bears against the corresponding rib of the adjacent member and so locks the parts :Of Vthe bale inposition around the tubes 12. The members `l5 diHer from the members 14 only'in being provided with a rib 19 which instead 'of-extending along the entire length of the member only extends through a very short portion of the length. The ribs 19 lock the members 15 in position in the same' manner as the ribs 18 lock the members 14. Each of the members 14 and 15 is provided, preferably just below the rib or projection 18 or 19, with an opening 2O for the insertion of a suitable tool for the rotation of they member. y

The baffle 13 upon the lower tier of tubes has its forward end extending over the grate chamber 8 composed ofy the members 14, while a portion of the rear .end over the combustion chamber 9 is composed of the members 15. The entire length of the tubes is thus protected and the products of combustion are revented from passing up through the orward end of the tubes but are allowed to pass up between the tubes at .the rear .end. In the upper batllel the position of the members 151s reversed, bein placed at the forward end of the tier o tubes in place of at the rear end. When it is desired to remove one of the members it is rotated partially about the tube, as shown at the central portion of Fig.4 2, and the adjacent pair of members are thus freed so that they may be rotated around the tubes and removed.

It will be seen that with my form of battle the members are comparatively'light in weight and not liable to bend the tubes,

and that the entire length of the tubes isI Each of the protected and at the same' time the products of combustion are properly guidedbetween the various tubes.

vHaving fully described myA invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. The combination with water tubes for boilers, of a bathe for said tubes composed of members the bodies of which are substantially semi-cylindrical, each member being provided with an integral laterally eX- tending rib, each rib having a convex surface and being adapted to engage with the rib of an adjacent member to lock said members in position around the tubes, said members being movable around the tubes to disengage said ribs.

2. The combination with water tubes for boilers, lof abaffle for said tubes composed of members the bodies of which are substantiallysemi-cylindrical, each member being rovided with an integral laterally eX- tendlng rib forming with the body an offset or shoulder, each rib having a convex surface and being adapted to engage with the rib of. an adjacent member to lock said mem-v` bers in position around the tubes, said members bein movable around the tubes to disengage said ribs.

3. The combination with water tubes for boilers, of a balie for said tubes composed of members the bodies of which are substancuasi tially semi-cylindrical, the bodies of each of said members being of substantially uniform thickness throughout, each member being provided with an integral laterally extending rib, each rib having a convex surface and being adapted to engage with the rib of an adjacent member to lock said members in position around the tubes, said members being movable around the tubes to disengage said ribs.

4, The combination with Water tubes for boilers, of a battle for said tubes composed of members the bodies of which are subl stantially semi-cylindrical, the bodies of each of said members being of substantially uniform thickness throughout, each member being provided at a point intermediate its edges with an integral laterally extending rib, each rib having a convex surface and being adapted to engage With the rib of an adjacent member to lock said members in positionlaround the tubes', said members being movable around the tubes to disengage sald ribs.

In testimony whereof I have hereunto set my hand and affixed my seal in the presence of the two subscribing Witnesses.

LEO WOERN ER.
