THE DACVIS VERTICAL-FEED-SEWING MACHINE.

Since Elia^-.How, ; in,hia.garret in Cam- - ' bridge, Massachusetts, first invented a sewing j machine in, 1846, many improvements have' been .made on that article of:- domestic use, t but mone has approached. nearer perfection than the new. Davis. Sewing Machine. This ; I machine- has taken the -first , prizes at the • Melbourne,Sydney and Adelaide Exhibitions,., and wIH doubtleaget another at the. forth-- - coming -Christchurch exhibition. Besides its , utility as a sewing machine it is * .very handy piece of furniture in which, are.- several,! drawers, and would be,, an ornament in any ■ room,. It has been patented by the Davis : Sewing Machine.- Company,Hew York, and* the local agent for it is.. Mr T* -Gk Rowley,, of TimarUj. to whose advertisement in another - column we desire to., draw attention. The ■ improvements in the, maqliine are described as follows: —A new shuttle made from a . solid steel-block and hardened, which is more * easily threaded than. others,.has less parts, , and none that can be broken or disturbed by use. . The.-milled shank, needle, .by which.-, device all sizes of.needles occupy precisely - same.position in relation . to the, cannot be set wrong fpr uge. An adjusWgle - needle plate, for sewings with large or small. needles, . The new patent thread, controller, which practically combines, the positive form , of some with the yielding form, of 'all other • machines, avoiding the defects of'either and ■ embracing the advantages of both. It over-. comes dropping stitches, breaking .and splitting cotton, silk and linen thread and requires -. no change of, adjustment to use - any size or - quality of them in any variety of work. It-, also handles- larger thread in a given size needle, than any other machine.- There also , added simple appliances- by which all 3 “ lost.motion” from wear by long use, can be taken,upland by.which apy one in a few minutes’ time can adjust any part of a worn.. ‘ machine •to its original position. An auto--matic bobbin binder is furnished with each . machine, by. which .bobbins are wound perfectly, uniform without the operator guidingthe thread.. The feed is, perhaps, the most important, if not the vital point connected j with any sewing machine, as upon its ac--curacy of-movement depends the regularity,. strength, evenness and perfection of stitching. , The feeds commonly in use m other sewing - , machines are known as> the ■ Wheelfeed, and / the Ratchet or I our Motion feed. The former consists-of. a revolving wheel which is . automatically moved forward at each stitch — - j the teeth of which project * sufficiently above - the bed of the machine to take hold of and, cai ry forward the fabric. The latter usually • consists of ,a horizontal under feed bar, whicl/i has a four motioned movement, produced by - complicated under gear. This feed bar is j. / also furnished with, teeth, which rise high j enough above the bed of the machine to . also take hold and carry forward the work, A.presserfoot in both cases comes down on f, the goods and holds them firmly to the sur. face of the feed. It must be obvious, then, that as the feed moves it must carry the - under ply faster than the upper, for the - simple reason that the presserfoot is retarding OS-holding back the upper ply while the feed is moving forward ; hence it is impossible ,to have both ends of the goods coma - out even —the underply must necessarily be t fulled or gathered on to the upper to some extent j so, that when, the strain is put upon the seam the stitches must break wherever it is gathered any, or wherever the goods are more, elastic than the thread. It has ; therefore become a. common practice among large clothing houses to cut the under ply • linger than the upper one, to allow for the. falling, so that both ends shall come out even,, This defect has brought a wejlmerited reproach upon sewing machines, SlEjdforms the mn.in reason why first-class tailors discard their use in seams requiring strength. This . great defect has existed since the first introduction of sewing machines, and until the in- ; rention of the “ Vertical Feed” principle which .is uplike any other feed and presents . t one ofj the distinguishing features of the W Davis Machine, which is destined to take precedence and bo placed at the the long list of first-class sewing machines at an early day. ."We recommenjd ladies paying a visit to. Tima.rn to go and see for themselves the., H work done by this machine which will be v . B shown to them by Mr T. GK Rowley, I
