Messrs Modelings, Onnnlugton, Dale, and Kirk, upon yon to defend your report, H. C. FISEB As CO. Chrlstoharoh International Exhibition, Jnne 15th, 1882. REPORT OP COMMITTEE OF EXPERTS. To BT. C. Fiskk & Co. DEAR SIB,—In acsordanoe with yonr request, we have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In oar comparison we have take a into consideration—

1. 'I he mechanical principle Involved 2. The quality of the material iwed 3. The degree of workmanship exhibited 4. The facility for doing a good and varied o 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 actuating the needle bar, viz., a crank with roller working in a cam. This cam In the Davis Machine is oat out of a solid piece of steel and hardened, while in the Singer it is not only very much lighter, i but is made of common oast iron.

The feed apparatus of the two machines are very dissimilar. That of the Singer la the usual slip feed. The Davis bat the vertical feed peculiar to itself. In this arrangement the pressor foot holds the material firmly down till the needle has' readied 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 atitoh. Motion la givf n to the Bhuttle In the Davis . machine as follows. An eooentrio at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits I it through a ball joint of Ingenious oonstrno tlon to the only moving, part nnder 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 movei a sliding shuttle oarrler. It will be seen that in ibe Davis there are between the main spindle and the shuttle four points of friction, the pivot carrying the vertioal 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 most liable to wear are made of hardened steel. To oompass the same work the Singer employs as points of friotlon the teeth of the mitre wheels, the two journals of vertioal spindle, the two ends of the connecting rod, and the sliding shuttle oarrler. 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 la a thin bar of iron, with a hole in each end. The 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 noticed that the shuttle of the Singer Machine is carried in a slide, to whioh a lateral strain is given by the driving rod, causing a certain amount of frlotion, 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, that car,not be out with an ordinary pookefc 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 quality of the material employed the the piece 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 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 effect of the pressure on a f >re 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 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 LBS SOOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PABCOK, Manager of the Kaiapol Clothing Faotory. GHO.
