The object of our invention is the iinprovemen of traclrenboards of his type Willi a view of permit ingr a more reedgy and thorough cleaning of 'one bleed-holes and other rluct'sor passages thereof.
In *'hc eccompenying drawings: Figure l is lransrc'e secion of e tracker board embodying invention. Fig. il is si, versi cal longiudinel section of a frcgrmens o flic tracker board taken 'ahrough inc bleedholes of he covering* nlae,

chamber arranged lengthwise in the top of the limer .section B and closed at ijs upper end a covering plato or strip L containing" a longitudinal series of small openings or bleed-holes one for nach. tracker-duct d. is carried by the lower Y. on of he tracker board so as to remain in place hereon when the upper section is renier 1d, but the plate is preferably removn said lower section. As Shown in ving, said. plate is arranged Hush ille upper surface of the lower section il, and for 'this purpose is countersunk in a recess herein. "in the construction shown in 'hc drau'ingyeach recker duct d, (Z1 is cm'inecofi will@ 'the chamber g' by lthe horiu zoolol passage e and a vertical channel or passage formed in the upper section A and leading from said passage to the con resoonding bleed-hole.

boeiA is closed` by a solid portion of Jche el. music sheet, the air is Withdrawn from t. ducs passages y'9 c, CZ, (Z1, Jclaus exair from the front 'as Well as the rear s e of the corresponding diaphragm or pneumatic, in the same manner in instrumente in which the Ibleed-holes are located in the Wind chest, thereby equalsing' the pressure on opposite sides of the diaphragm. and allowing it to remain in its nerriai position in which the valves operusted by it'cut oil coinmunicat-ion'bctween the corresponding motor pneumatic and the exhaust chamber of the wind chest, in"a Well lmovvnfinenner. At the saine time any dust, linib7 30., in the tracker ductsy and t ase end j are drawn toward and deposited against the upper side of the bleedhole sirip or cover fi; from which 4theymm be easily removed when required, by an 0rdi` nary brush or L cleaning cloth, after removing; iop section A of `the board but with anc actions operaed by either air-l chamber 9' through. When a noteduct d, Z1 of out necessitating the removal of the strip from the lower section. of the tracker board. The dustfreceiving side otsaid strip is thus fully exposed and easy o'l access, permitting it to be thoroughly cleansed, especially when arranged `flush with the top of the lower sectionVV E, as shown inthe drawing. By dif viding the tracker board into separable face and base sections and removably arranging the strip or plate It at the junction of the two sections, the tnrther advantage is obtained that the plate is readily accessible upon separating the sections, permitting the plate to be easily removed for renewing it or other purposes, y the use ot a knifeblade or other suitable means. The transverse passages c and the upper portions (Z of the tracker ducts can also be cleansed by removing the cover '1 and delivering an airblast into the outer ends of said passages by means ot hand-bellows or other suitable means. v

bleed-dnct arrangedin one section at its 'unction With the other section, and a covering plate extending across said bleed-duct at said junction and having bleed-hole come municating with said note-duct, said covering plate being carried by one of the sections ofthe tracker board.
3. A tracker board comprising separable sections and having a main or note-dugt, a (bleed-duct arranged in one section, a covery sections and having a ing 'plate applied to said bleed-duct and having a bleedh'ole, and a passageleading from said note-duct to said bleed-hole, said covering plate being` carried by one of the sections of the tracker board. i
A tracker board comprising separable sectionsand having a main or note-duct, a bleed-duct arranged'in one section, 4a covering plate applied to said bleed-duct and ar ranged substantially flush with the face of the last named section, said plate being carried by said last named section and containing a bleed-hole, and a section leading from said note-duct to said passage in the other bleed-hole, said plate' being arranged be- I tween the sections.
