NOT QUITE SO DECISIVE AS IT WAS BUr A LITTLE MORE OVBBWHELMING. WE 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 facts, vesars Meddings, Connington, Dale, and Kirk, we call upon you to defend your report. H. C. FIBKB & CO. Chrlstohnroh International Exhibition, June 15th, 1882. REPORT OP COMMITTEE OF EXPERTS.

To H. C. Fiskk & Co. SIB, —In accordance with your request, we have examined the New Davis and the New Binger 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 4 The facility for doing a good and varied o ass of work. After taking both machines asunder, carefully examining every piece, and fully testing their capabilities, we have no hesitation in saying that we consider the Davis far the superior maohiee of the two. Our reasons are aa 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 ont oat 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 machines are very dissimilar. That of tho Singer is the usual slip feed. The Davis has the vertical feed peculiar to it-ielf. In this arrangement the pressor foot holds the material firmly down till the needle has' reached its lowest paint. 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 etitoh. Motion is givf n to the shuttle in the Davis machine as follows An eccentric at tha wheel end of the main spindle gives motion to a vertical lever. This in tarn transmits it through a ball joint of ingenious oonstruo tlon to the only moving part under the 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 roi from this crank moves a eliding 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 eooentrlo and the ball joint, are adjustable, and the parts most liable to wear are made of hardened steel. To oompaßs the same work the Singer employs as points of friction 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 cast iron, having a certain amount of backlash, and consequent tendency to rattle and and break. The connecting rod id a thin bar of iron, with a hole in each end. The end which runs on the crank pin is one of the prlnoipal joints in the machine, having a considerable amount of work to da. with small bearing Barf ace, 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 Machine is oarried in a slide, to whioh a lateral strain 1b given by the driving rod, causing a certain amount of friction, while in the Davis it is curried by the lever quite free from Motion. 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, that oatinot be cat with an ordinary pooket knife, and there are no means of adjusting any wearing part. In the Davis not only are moat 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 the 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, sewin from the thinnest mnslln to even throu h a metal spoon, the Davia has no paralle grasp, or for avoiding that puckering of Jen the effect of the presaure 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 mechanioal principles involved, and also in performing a greater range of work. We found the Davis to work with eqaal ease from the lightest to the heaviest fabric. JOHN LEE SOOTT (Scott Bros.), Mechanioal Engineer. T. GLUYAB PASCOE, Manager of the Kaiapol Clothing Factory. GEO.
