BisKK & Co. DEAR ’SIB, —In accordance with yonr request, we have examined the New Davis and the Now Singer Sewing Machines, for tho purpose of comparing them. In our comparison we have taken Into consideration— 1, Ihe mechanical principle involved 2, The quality of the material used 3. The degree of workmanship exhibited 4. The facility for doing a good and varied a ass of work. After taking both machines ooandor, carefully examining every pleoe, and fnlly 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 crank with roller working in a cam. This oam In the Davis Machine la out ont of a solid piece of steel and hardened, while In the Singer it Is not only very much lighter, bat 1b 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 peculiar to itself. In this arrangement the presser foot holds the material firmly down till the needle has reached Its lowest point. The pressure la then relieved and transmitted to the feed bar. Food 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 machine as follows. An eooentrio at the wheel end of the main spindle gives motion to a vertical lever. This In torn transmits It through a ball joint of ingenious construe tlon to the only moving part under the machine, a pivotted 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 crank. 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 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 eooentrio and the ball joint, are adjustable, and the parts moat liable to wear are made of hardened steel. To compass the same work the Singer employs as points of frlotlon 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 amonnt of backlash, and oonseqnent tendency to rattle and and break. The connecting rod Is a thin bar of Iron, with a hole In each end. The end wbloh runs on the crank pin la 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, aa before remarked, there are no means of compensating for any wear. It will be noticed that the shuttle of the Singer Machine la carried In a slide, to whloh a lateral strain la given by the driving rod, causing a certain amonnt of friction, while In the Davis It la carried by the lever quite free from friction. With the exception of the small roller working the needle bar, there la not a single piece in the Singer Machine, not even excepting the shuttle, that oar.net be cat with an ordinary pooket knife, and there are no means of adjusting any wearing part. In the Davta not only are most of the pieces made of steel, and tempered, bat at every essentia] point meana are provided for taking up any wear. On this point we may say that where we had any donbt about the quality of the material employed the the pleoe was broken and the fracture carefully examined. Having examined the mechanical 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 moolln 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 onr astonishment at the range and variety of work accomplished by the Davis, which 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. Wa found the Davis to work with equal ease from tho lightest to tho heaviest fabric, JOHN LEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLUT AS PAHOOE, Manager of the 'Kaiapol Clothing Factory.
