Messrs Meddings, Cunning ton, Dale, and Kirk, we Jcali upon you to defend your report. H. C. FISKE & CO. Christohnrch International Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskb & Co. I YEAR SIR, —In accordance with your 3J request, we have examined the New Davis and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison we have takej into consideration— 1. The mechanical principle Involved 2. The quality of the material used 3. The depree 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 eaylng that we consider the Davis far the superior machine of the two. Our reasons are as follows : In both machines the e.»mo method is adopted for actuating the needle bar, viz., a ordtik with roller working in a cam. This cam in the Davis Machine is cut out of a solid piece of steel and 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 vertical feed peculiar to itoe.f. In this arrangement the presser foot holds the material firmly down till the needle hat reaohed Its lowest point. The pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material ar< then, by a very simple contrivance, movec forward simultaneously the required lengtt of stitch. Motion is givin to the shuttle in the Davir machine as follows An eccentric at thi wheel end of the main spindle gives motioi to a vertical lever. This in turn transmit:, fit through a ball joint of ingenious construe tion to the only moving part under the maohine, a pivotted lever having at Its en< an adjustable shuttle carrier. In the Singe: Machine a pair of mitre wheels drive a vertical spindle, having at its lower end a crank A connecting rod from this crank moves i sliding ehuttle oarrler. It will be seen tha in the Davis there are between the mail spindle s.nd the shuttle four points o friction, the pivot carrying the vertical level the eccentric, the ball joint, and the pivot o: horizontal lever. The two principal move mentß, the eccentric and the ball joint, ari adjustable, and the parts most liable to wea: are made of hardened steel. To oompas the same work the Singer employs as point; of Motion the teeth of the mitre wheels , the two journals of vertical spindle, the tw ends of the connecting rod, and the slidlD shuttle carrier. None of these places ar adjustable. The small wheels are commo: cast Iron, having a certain amount of back lash, and consequent tendenoy to rattle an and break. The connecting rod id a thin ba of Iron, with a hole in each end. The em which runs on the crank pin is one of th considerable amount of work to do wit small bearing surface, making it very llabl to wear, while, as before remarked, there ar no means of compensating for any wear, j ; It will be noticed that the shuttle of th Singer Maohine is carried in a slide, t which a lateral strain is given by the drivin rod, oausing a certain amount of friction while In the Davis it is carried by the leve quite free from friotion. With the exception of the small rolle working the needle bar, there is not a sing] piece in the Singer Maohine, not even ex ceptlng the shuttle, that car.not be cut wit an ordinary pooket knife, and there are n means of adjusting any wearing part. I; the Davis not only are most of the piece made of steel, and tempered, but at ever; essential point means are provided for takin, up any wear. On this point we may sa; that where we had any doubt about th . quality of the material employed th the piece was broken and the fracture care fully examined. Having examined the meohanioal arrange ments of the two machines, we tested thel adaptability for work, and we notloed th very peculiar feed of the Davis. In thi respeot wo have been forced to the concln sion that for all purposes, sewing from th thinnest muslin to even through a meta spoon, the Davis has no parallel for grasp, o for avoiding that puckering often the effec of the pressure on a fare motion feed. W' must In common honesty express ou astonishment at the range and variety o work accomplished by the Davis, whiol we are satisfied cannot be done by th< Singer. In summarising our report we repeat tha we have no hesitation in saying that wi regard the Davis as very superior to thi Singer in workmanship, material, and thi mechanical principles involved, and also ii performing a greater range of work.
