pose so long as they will stand the work. Your committee agree, 

 that the value of this arrangement lies in the following points : 



First. The facility with which the most ordinary workman can 

 construct such a machine, in any place where he can get the wood 

 and tools; as the whole may be keyed and pinioned together with 

 wood, and made with wood gudgeons, where iron cannot be had, and 

 from the way in which the shafts are held, in vibratory levers, if the 

 horse wheel, from haste, shrinkage, warping, or hard work, " gets 

 out of truth^'' the shafts and levers will so accommodate themselves 

 to any undulatory motion in the wheel, that the work required can 

 still be progressed with. 



Second. A well made wheel and pinions will last many years with- 

 out repairs, and if the wheel grooves get worn wider, a packing 

 placed between the annular ring and cover plate of the pinions, will 

 spread the pinion, to fill out the worn space, and make the parts ef- 

 fective again. 



Third. The advantage your committee considers the most impor- 

 tant, is a greater security from injury by accident or design than they 

 have seen in any machine of equal power ; for, if the levers and 

 weights are properly adjusted, any strain exceeding the strength of 

 the parts, which would break a wheel fitted in the ordinary manner, 

 and cause loss, and probably personal injury to some one, will be here 

 evaded by the pinions and grooves slipping over each other. If a 

 stone or other substance gets in a groove, the pinions will, in a great 

 majority of cases, overleap it by the vibratory lever allowing the pi- 

 nion to rise without injury, and the most violent efforts of a restive 

 or unmanageable horse can hardly derange the connection of the 

 parts. 



Your committee concur in the belief that Mr. Scripture is entitled 

 to great credit for having brought forward a cheap, safe, effective and 

 permanent horse power, which appears to them deserving of encou- 

 ragement from any one requiring such a machine. 



Respectfully submitted.
