C. Fiskk & Co. DEAR SIR, —In accordance with your request, we have examined the New Davis and the New Singer Sewing Maohu.es, for the purpose of comparing them. In our comparison we have taken into consideration — • 1. Ihe mechanical principle Involved 2. The quality of the material used 4. The facility for doing a good and varied o'ass of work. After taking both machines asnnder, care- ) fully 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 actuating the needle bar, viz,, a ) orank with roller working in a cam. This cam 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, t but is made of common oast iron. The feed apparatus of the two machines ■ are very dissimilar. That of the Singer is the usual slip feed. The Davis has the , vertical feed peouliar to It-self. In this arrangement the presser foot holds the reaohed 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 oontrivanoe, moved forward simultaneously the required length of stitch. Motion la given to the shuttle In the Davis machine 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 maohlne, a plvotted lever having at Its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a vertical spindle, having at its lower end a orank. A connecting rod from this crank moves a sliding shuttle oarrier. It will be seen that in the Davis there are between the main spindle and the shuttle four points of friction, the pivot carrying the vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever, The two principal movements, the eccentrlo and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To compass the same work the Singer employs as points of Motion the teeth of the mitre wheels, 1 the two journals of vertloal spindle, the two ends of the oonneoting rod, and the sliding shuttle oarrier. None of these places are adjustable. The small wheels are oommon 1 cast iron, having a certain amount of backlash, and consequent tendenoy to rattle and and break. The connecting rod id a thin bar of Iron, with a hole in each end. The end whloh runs on the crank pin is one of the prlnoipal 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 noticed that the shuttle of the Singer Maohlne la carried In a slide, to whloh a lateral strain 1b given by the driving rod, causing a oertaln amount of friction, while In the Davis It Is curled by the lever , quite free from friction. With the exception of the small roller working the needle bar, there is not a single piece in the Singer Maohlne, not even excepting the shuttle, that car. 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 places made of steel, and tempered, but at every essential point means are provided for taking np any wear. On this point we may say that where we had any doubt about the quality of the material employed the the pleoe 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 respeot wa 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 effeot 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 performing a greater range of work. We found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.), Mechanical Engineer, T. GLUYAS PA3COE, Manager of the Kaiapol Clothing Factory. GEO.
