DEAR SIR, —In accordance with your request, we have examined the New Davis and the New Singer Sewing Maohines, for the purpose of oomparlng them. In our comparison we have taken Into consideration— 1. The meohanioal principle involved 2. The quality of the material used 3. The depree of workmanship exhlbltsd 4. The facility for doing a good and varied el ass of work. After taking both maohines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines the same method is adopted for sotnatlng the needle bar, viz., a crank with roller working In a cam. This oam In the Davis Machine is out out of a , solid piece of steel and hardened, while in the Singer it is not only very much lighter, bnt Is made of common oast iron. The feed apparatus of the two maohines are very dissimilar. That of the Singer Is the usual slip feed. The Davis has the { vertical feed peculiar to ltielf. In this arrangement the pressor foot holds the material firmly down till the needle has reached Its lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion Is given to the shuttle In the Davis maohine as follows. An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This In turn transmits it through a ball joint of ingenious oonstruo tlon to the only moving part under the maohine, a pivotted lever having at Its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertical spindle, havirg at its lower end a orank. A connecting rod from this crank moves a sliding shuttle carrier. It will be seen that in the Davis there are between the main spindle aad the shuttle four points of friction, the pivot oarrying the vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. The two principal movements, the eooentrlo and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To oomp&ss the same work the Singer employs as points of friotion the teeth of the mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle carrier. None of these places are adjustable. The small wheels are common oast iron, having a certain amount of backlash, and consequent tendency to rattle and and break. The connecting rod is a thin bar of Iron, with a hole in each end. Tne end whioh runs on the crank pin is one of the principal joints in the machine, having a considerable amount of work to do with small bearing surface, making It very liable to wear, while, as before remarked, there are no means of compensating for any wear. It will be notloed that the shuttle of the Singer Maohine is oarried in a slide, to whioh a lateral strain is given by the driving rod, causing a certain amount of friction, while in the Davis It is oarried by the lever quite free from friotion. With the exception of the small roller working the needle bar, there Is not a single piece in the Singer Maohine, not even excepting the shuttle, that cat;not be out with an ordinary pocket knife, and there are no means of adjusting any wearing part. In the Davis not only are most of the pleoes made of steel, and tempered, but at every essentia] point means are provided for taking up any wear. On this point we may say that where we had any doubt about the quality of the material employed the the piece was broken and the fracture carefully examined. Having examined the meohanioal arrangements of the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect wo have been forced to the conclusion that for all purposes, sewing from the thinnest muslin to even through a metal spoon, the Davis has no parallel for grasp, or for avoiding that puckering often the effect of the pressure on a fore motion feed. We must In common honesty express our astonishment at the range and variety of work accomplished by the Davis, whioh we are satisfied cannot be done by the Singer. In summarising our report we repeat that we have no hesitation in saying that we regard the Davis as very superior to the Singer In workmanship, material, and the mechanical principles Involved, and also in found the Davis to work with equal < from the lightest to the heaviest fabric JOHN LHE SOOTT (Scott Bros.), Meohanioal Engineer.
