NOT QUITE 80 DECISIVE AS IT WA' 1 , ' BUT A LITTLE MOKE OVERWHELMING. 1 WE CHALLENGE tho representative of tho Singer Sewing Machine Company, or any of the jurors on Sowing | Machines at the Exhibition who voted for , the report coming from that body to controvert the following statement of facts Messrs Weddings, Ounnlngton, Dale, and Kirk, wo call npon you to defend your I report. 1 H. O. FIBRE & CO. Christchurch International Exhibition, Juno 16th, 1882 REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskk Ac Co. DEAR SIB, —In accordance with your request, we ha\o examined tho Now Davis and tho New Singer Sowing Machines, for the purpose of comparing them. In our comparison wo have taken Into consideration— 1, The mechanical principle Involved 2. The quality of the material u*ed 3 The degree of workmanship exhibited 4. The facility for doing a good and varied c css 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 tho Davis far the superior machi-.o 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 ent 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 sppsratua of the two machines are very dissimilar. That of the Singer is the usual slip feed. Tho Davis has the vertical feed peculiar to itself. In this arrangement the presser foot holds the material firmly down till tho needle has reached its lowest point. The pressure is theu 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 stitch. Motion is giv. n to tho shuttle In the Davis machine as follows An eccentric at the wheel end of the main spindle gives motion to a vertical lever. This in turn transmits it through a ball joint of ingenious construction to the only moving part under the machine, a pivotted lever having at its end ■ an adjustable ehnttle carrier. In the Singer I Machine a pair of mitre 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 bo seen that in the Davis there are between the main spindle and tho shuttle four points of I friction, tho pivot carrying tho vertical lever, the eccentric, the ball joint, and the pivot of horizontal lever. Tho 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 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. Tho small wheels are common cast Iron, having a certain amount of backlash, and oonseqm nl tendency to rattle and and break. The connecting rod lo a thin bar of iron, with a hole in each end. The end which 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, aa 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 which a lateral strata is given by the driving rod, causing a certain amount of friction, while in the Davis it is curried 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 ca not be cut with an ordinary pocket 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 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 tho conclusion that for all purposes, sewing from the thinnest muslin to even through a metal spoon, tho 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 our astonishment at the range and variety of work accomplished by the Davis, which wa are satisfied cannot be done by the Singer. In summarising onr report we repeat that wo have no hesitation in saying that we regard the Davis as very superior to the Singer in workmanship, materia), and the mechanical principles involved, and also in performing a greater range cf work. We found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LEE SOOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PABCOE, Manager of the Eaiapoi Clothing Factory.
