NOT QUITE SO DECISIVE AS IT WAS tUf A LITTLE MORE OVERWHELMING. 'E CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of faots. Messrs Meddings, Connlugton, Dale, and Kirk, we call upon yon to defend yonr report. H. C. PISKE & CO. Chrlatchurch International Exhibition, June 15th, 1882, REPORT OP COMMITTEE OP EXPERTS. To H. C. Fiske & Co. DEAR SIR, —In accordance with yonr request, we have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have taken into consideration— 1. '.the mechanical principle involved 2. The quality of the material u-ed 3. The decree of workmanship exhibited o ass of work. .After taking both machines asunder, carefully examining every piece, and fully testing thijir 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 tee ss.me method is adopted for tctuating the needle bar, viz,, a crsnk with roller working in a cam. Thiß cam In th« Davis Machine is out out of a solid piece of steel aud hardened, while in the Singer it is not only very much lighter, 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 vertioal feed peculiar to itself. In this arrangement tha 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. Fsed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion io givtn to the shuttle In the Davis machine an follows. An 6ccentric at tha wheel end of the main spindle gives motion to a vertical lever. This in turn 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 mitro wheels drive a vertical spindle, havi: g 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, tha ball joint, and the pivot of horizontal lever The two principal movements, the eccentric 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 friction the teeth of the mitro wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle carrier None of these places are cast iron, having a certain amount of backlash, and consequent tendency to rattle and and break. The connecting rod la a thin bar of iron, with a hole in each end. The end which runs on the crank pin is one of the prinoipal joints in the machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while, aB before remarked, there are no means of compensating for any wear. It will be noticed that the shuttle of the Singer Machine is carried in a tlide, to which a lateral strain is given by the driving rod, causing a certain amount of friction, while in the Davis it is carried 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 Machine, not even excepting the shuttle, th*t ca.not be cnt with an ordinary pooket knife, and there are no means of adjusting any wearing part. In the Davis not only are most of the pieces made of steel, and tempered, but at every essential 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 tho piece was broken and the fracture carefully examined. Having examined the mechanloal 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 muelin to even' through a motal spoon, the Davis has no parallel for grasp, or for avoiding that puckerirjg 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, which we are satisfied cannot be done by the Singer. In summariiiog 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 psrforming 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 PABCOE, Manager of the Kaiapol Clothing Factory. GEO.
