NOT QUITE SO DECISIVE A 3 IT WAS BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE the representative of the Singer Bewing'Mtohine Company, or any of the'jnrora on Sewing Machines at the Exhibition,’ who voted lor the report coming from that body to controvert the following ' statement of facts. Messrs Meddings, Cnnnlngton, Dale, and Kirk, we "call npon you to defend your report* H. C. FIBKB & CO. Christchurch International Exhibition, June 15th, 1882, REPORT OF COMMITTEE OF EXPERTS.
To H. C. Fiskb & Co, BEAR SIB, —In accordance with your request, we have examined the New Davie and the New Singer Sewing Machines, for the purpose of comparing them. In our comparison wo have taker into consideration— 1. The mechanical principle Involved 2. The quality of the material used 3, The degree of workmanship exhibited i 4, The facility for doing a good aod 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 tho 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 ont out of a solid piece of steel and hardened, while In the Singer it is not only very much lighter, but is made of oommon oast iron. Tho feed apparatus of tho two machines are very dissimilar. That of the Singer Is the nsual slip feed. Tho Davis has the
vertical feed peculiar to Itself. In thia arrangement the preaser foot holds the material firmly down till the needle haa reached its lowest point. The pressure la 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 stitch. Motion Is given to the shuttle In the Davis machine as follows. An eccentric at tho 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 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 be seen that in the Davis there are between the main spindl e iud 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 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 frlotlon 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 back.
lash, and consequent tendency to rattle and and break. The connecting rod is 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, 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 which a lateral strain la 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, that cannot be ont with an ordinary pocket knife, and there are no moans 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 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 peonliar feed of the Davis. In this respect wo 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 fore motion feed. We mnst 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 summarifing oar 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 eqcal ease from the lightest to the heaviest fabric. JOHN LEI 3 SOOTT (Scott Bros.), Mechanical Engineer. T.
