1823,] Mr. Weekes's Description 



viz. Ihe box or receptacle of what is 

 inore properly to be considered as the 

 musical iastrumeiit, is best construct- 

 ed of well-seasoned fir, of about a 

 quarter of an inch in thickness, which, 

 as it is to be exposed occasionally 1o 

 tlie external atmosphere, it woald be 

 ndvisable to paint agreeably to fancy, 

 and to lay over the palutiug a good 

 coating of durable Tarnish. The fol- 

 lowinst tecipe answers exceedingly 

 well for all works of this description, 

 required for out-doors purposes: — 

 Take of rectified spirits of wine twelve 

 ounces, gum-sandarach four ounces, 

 seed-lac one ounce, pure resin two 

 ounces : dissolve in a warm situation 

 in a wide-mouth bottle, and subse- 

 quently add three ounces of good Ve- 

 nice-turpentine. 



The pillar or column by which the 

 whole apparatus is supported siiould 

 be neatly turned of some hard species 

 of wood, tlie claws or feet made to 

 extend sufticicntiy wide, in order that 

 the machine may stand firm, and not be 

 rendered liable to overturn by gusts of 

 wind. The pillar may also receive a 

 coating of varnish, as above directed. 

 'I'he instrument, when neatly made, 

 makes a pleasing and elegant appear- 

 ance.

 profile or end-view of the exlernal box 

 or case of Ihe instruuicnt, will convey 

 an acciiratf^ idea of tin; necessarily 

 irregular shape, open :ind covered 

 parts of the wbolf niacliiru', il' the ob- 

 server bears in mind. tli;it every part 

 <if the outline of this eiid-view is to be 

 (overed by a thin board of fir, stretch- 

 ing longitudinally, <\( t-pt the line-;

Fig. 2,— A, IJ, C. 1>, .sliil.ils an 

 (dilifjne front view dI' the iiiHchnic for 

 containing the musical (blinder, here- 

 after to be deseribrd. !)irerily in the 

 middle of the front ol this purlion of 



the machine is seen projecting to the 

 distance of several inches, and extend- 

 ing longitudinally throughout its 

 whole length, a triangular prism- 

 shaped part d e, connected with the 

 box, and formed by covering the an- 

 gular projecting head-boards, (one of 

 which is represented by c, in Fig. 1.) 

 with thin deal, similar to the rest of the 

 external parts of the machine. The 

 longitudinal covers or sides of this 

 projecting portion, which is denomi- 

 nated the compresser, from the office to 

 which it is destined, rest on the two 

 angular head-boards f and ff, but do 

 not approximate as they approach the 

 sides of the box A, B, C, D, being pur- 

 posely so contrived as to leave a nar- 

 row slit or aperture extending from/ 

 to ff, of about half an inch in width, 

 through which a current of air may 

 find free access to the cylinder, having 

 a rotary motion upon an axis within 

 the machine.

Fig. ;{. represents a rather oblique 

 view of the back part of the instrument 

 in a complete state, and adapted to 

 use. Within the box of the machine 

 here delineated, the back part of 

 which is best left open when in use, 

 I)Ut may be made to shut up by a drop 

 folding door, with hinges, at pleasure.
