SHUTTLE EMBROIDERY MACHINE Application filed September 28, 1923. ,Serial No. 665,379.
To yf/ZZ 10i-1.0m it may concern:
Be it known that I, MAX BnETsoHNnIDER, a citizen oi the German Republic, and a resident of Plauen, Saxony, Germany, have invented a new and useful Shuttle Em broidery Machine, of which the following is a specication.
rlhis invention relates to shuttle-embroidery machines; more especially, it relates to shuttle embroidery machines operating with several needles and with a bead-carrying In order to be in the position to work such a thread on a multiple-needle embroidery machine, the thread must be passed through the needle ear trom above to below so that the beads can follow the thread in the right mannerA and without ln view ot this the `shuttle must be reciprocated on the bottom side of a horizontal shuttle path located above it, the shuttle being, therefore, as it were, suspended. This has already been proposed but there arises the diiiicnlty that, on one side, the shuttle must be pressed. against the shuttle path in order to pass securely through the thread-loop, and that, on the other side. its guiding and carrying parts must not impede the thread when it glides away over the back of the shuttle. Besides, attention must be paid to the feature that an accurate adjustment of the shuttle by means of the drivers remains possible.
All these various requirements are responded to by my invention, the gist of which consists in the shuttle being placed between the drivers into a basket and being slightly pressed upwards against the shuttlepath by a soit spring provided therein, the foremost part of the spring being curved upwards in such a. manner as to represent a kind of trough so that it contacts with the shuttle only at one point and the embroidery thread can pass easily between the spring and the shuttle when this latter passes through the thread loop.
My invention is illustrated by way of example in the accompanying drawing, in which Figure 1 is a cross-section of those parts of the embroidery machine which are necessary to carry the invention into practice. Figure 2 is a rear view of the parts shown in Figure 1. Figures 3 and 4 are a front-view and a side-view of a driver and Figures 5 and 6 are a front-view and a sideview of the shuttle-basket while Fig. y7 is a cross-sectional view of a detail part, shown invFig. 5, but `drawn'on larger scale, as is all fully described hereinafter.A
The shuttle l is pressed `from below against the shuttle path 2 which liesabove it and is provided in known manner with a needle channel in which the needle 4 reciprocates after it has pierced the fabric. The shuttle path 2 is carried by the stitch-plate 5 which is attached to` the trough-shaped longitudinal carrier 6.
Attached to theinner side ot the carrier 6 are guide brackets 7 in which the sofcalled stones 8 are 4shiftable in known manner. The stones 8 are a'liixed tothe lower side of a. driver rail 9 and afford this latter a secure hold, as well `as a. reliable lguidance when being reciprocated in the longitudinal direction of the machine in order to move the shuttles through the thread loops at every embroidering action. l
On the upperside of the driver rail 9 are for each shuttle twol drivers 10 `and 11 a'flixed by a clamp 12 and a screw 13,-the activel end of the clamp bearing on a flattened `part of the drivers 10 and 11 which are round and are prevented in this way from assuming a wrong position. As the drivers are `lJ-shaped Fig. 4)-, their upper part can be bent easily around'the vertical central part in order to adjust the'shuttle.l
The two drivers'are of different height, that driver which (zo-operates with the point of the needle being about 2 mm. lower than the other which abuts therear part of the shuttle in order to prevent the front driver from distorting the thread loop and disturbingV thereby the proper passage of the shuttle therethrough.
Between the drivers is arranged the shuttle carrier 14 which is a U-shaped part made of band-iron and being sho-ved into a corre-` sponding guide-groove of the driver rail 9.`
Over the lower leg of the shuttle carrier 14 extends from both sides a flat spring 15 by which the carrier is pressed against the driver rail so that the driver is prevented from` sliding back spontaneously, without, impeding, however, the operator .from grasping it easily and quickly with his iingers in order to exchange the shuttle.
The lower leg of the carrier 14 isvprovided with an oblong slot 16 through which extends a screw 17 which serves as stop for the shuttle carrier and prevents it from being drawn forward too much when the shuttle is exchanged. The length of the springs 15 is such that each can be secured in place by two neighbouring screws 13 belonging to two clamps 12, as shown in Fig. 2. Each of these springs has between its active ends an upwardly extending part 18 made integral with it and being so long and so high that the gap between the driver rail 9 and the shuttle path 2 is so much covered that the shuttle cannot tall into this gap when the shuttles are exchanged.
At the rear end of the carrier 14- a small tongue 19 which is stamped, and bent, out of the plane of the shuttle carrier 14 and serves to allow oi' withdrawing this carrier easily along its guide on the driver rail 9. 'Lo the front end of the upper leg o the shuttle carrier is rigidly aiiixed the shuttle basket proper, the front part of which is shaped similarly to a trough, in such a manner that it can take around the back of the shuttle. A. recess 21 is engaged by a narrow and very soft flat spring 22 which is ailixed to the inner side of the shuttle carrier and can be adjusted by the screw in such a manner that it presses the shuttle 1 just with a soft pressure against the shuttle path 2. The foremost part ot the spring 22 is provided with a downwardly open groove 24 extending in the longitudinal direction of said spring, that is to say, transversely to the back of the shuttle 1. rlhe spring contacts with the shut-tle by the back of that upwardly curved part, the shuttle being, thus, carried merely at one point so that the thread can pass through at this point with but very little friction. The vaulted part of the spring prevents the edges of this latter from. acting like cutting edges on the thread, as well as from destroy ing the thread by a clamping action othei-` wise arising between the parts mentioned.
@n the rear edge of 'the longitudinal carrier 6 is fastened a protective shield 25 extending forward to near the driver rail 9 so that the shuttles which have been taken out cannot fall into the interior of the trough-shaped main carrier 6 where it would be diliicult to take hold ot them.
I claim:
1. A shuttle embroidery inarhine, com
prising, in Combination, a plurality otneedles, a member forming a shuttle path, a shuttle located below this path, a basket containing the shuttle, and a spring arranged in the basket below the shuttle and pressing this lat-ter against the shuttle path, the front end of said spring being vaulted transversely to the shuttle back, as set forth.
2. A shuttle embroidery machinen comprising, in combination, a plurality ot needles7 a member forming a shuttle path, a shuttle located below this path, a basket containing the shuttle, a spring arranged in. the basket below the shuttle and pressing this latter against the shuttle path, the front end of said spring being vaulted transversely to the shuttle back; drivers for the shut tle, and a driver rail, the basket being shi 'table on said rail: transversely to the diret'- tion of movement oit the shuttle independently of said drivers, the latter being at fixed to the' said rail at the two sides oi the basket, as set forth.
l'n testimony whereof I alix my signature in presence of two witnesses.
MAX BRETSCHNElDER.
