Application filed April 14, 1915. Serial No. 21,365.
To all whom it may concern: I
Be it known that I, J OSEPH JAMns BRIGGS, a subject of the King of Great. Britain and Ireland, residing at Belfast, Ireland, have invented certain new and useful Improvements in and Relating to Embroidery Attachments for Sewing-Machines, of which the following is a specification.
This invention relates to so called duplicating attachments for use in connection with embroidery and like sewing machines and of the class by means of which a worker can simultaneously reproduce a number of repeats from a single pattern, and it has for its object to provide improved devices of this class which permit of a practically universal movement of the work holder and whereby the movements of the work holder controlled by the operator are simultaneously and accurately repeated by the other work holders, thus producing the repeats as required.
Under my invention I employ parallel link motions or equivalent to produce the required automatic repeating of right and left, and back and forward movements of the work holder controlled by the operator, which movements are, by said parallel link motions, communicated to the other work holders. Turning movements of the work holder controlled by the operator are, or may be, simultaneously repeated at. the other work holders by connecting each work holder with a turnable wheel at the end of a supporting bar or equivalent, the other end of said bars or equivalent being pivotally connected to the parallel link motions which give right and left hand movements, while intermediate the two ends of each bar I provide another wheel or equivalent, and connect said last mentioned wheels by a parallel link motion or equivalent, so that the turning of one wheel will simultaneously and similarly turn the other wheels of the series, while each of said wheels is pivotally connected at its center with the parallel link motion which produces back and forward movements, the movements of the first mentioned wheels connected with the work holders are communicated to the last mentioned wheels by adjustable belts, or bands, or
chains, and for this purpose I find that in practice, bands of steel or of covered whalebone are very suitable and free from any backlash or stretching. The parallel link motions or any of them may be arranged above or below the work bench as desired, or as may be found most convenient For the purpose of illustrating my invention I have shown on the annexed drawings certain embodiments thereof, but it is to be understood that my invention is not limited to the exact arrangement and organization of parts as herein set forth. 7
Figure 1 is a front elevation of a duplicat ing apparatus in accordance with my inveni tlon.
Fig. 2 is a plan view thereof.
Fig. 3 is an enlarged front elevation of one unit of the apparatus.
Fig. 4c is a plan view of Fig. 3.
Fig. 5 is a side elevation looking in the direction of the arrow on, Fig. 3.
Fig. 6 is a side elevation and Fig. 7 is a plan view of a slightly modified form of the apparatus.
On the drawings the same reference letters wherever repeated indicate the same or similar parts.
Referring to the drawings and the example of my invention shown at Figs. 1 to 5 inclusive, the hoops or thelike a are each removably secured to a semicircular supporting bracket or holder 6 which is, or may be, hinged'or otherwise secured at 6 (see Figs. 3 to 5) 011 pins carried by a rotatable spindle 0 which is supported in the forked end (Z of a lever (Z, the spindle 0 having secured thereto a wheel 0 and the lever d which supports the spindle 0 and wheel 0 is pivotally supported on a spindle 6 carried by the forked end 7 of a lever f which is pivotally supported at its end P on a spindle g supported in a bearing which maybe fixed to the work bench or which may as in the example shown, he carried by a slidable bar 71.. The bar 72. would preferably, as shown in Fig. 5 be adapted to slide on rollers 71, suitably supported.
The lever 03' which is pivotally supported on the spindle 6 extends rearwardly, and at its end Z it pivotallyi supports a link or its is obtained.
thereto has also a' wheel 0 secured wit and a band or belt 1) connects the wheel 0 with the wheel 6 so that any turning movement of the wheel 0 will produce a corresponding movement of the wheel 6 and by means of the cranks Z and link m all the wheels 6 and 0 will be correspondingly and. simultaneously turned so that the turning of one hoop a will correspondingly and simultaneously turn all the other hoops a. A; transverse movement of one of the hoops a will cause the lever d connected therewith to move the lever f and its spindle g and correspondingly move the crank 0 secured thereto and v by means of the link a a corresponding and si-' multaneous movement of the other hoops c4 7 Longitudinal movements of one of the hoops a will move its corresponding lever (8 about its spindle a so that its end 03 will correspondingly move the link 70 and so simultaneously give a corresponding longitudinal movement to the other hoops a of the apparatus. The cranks [and link m and the cranks 0 and linkn could be re-- placed by pulleys and suitable driving. means such as shown in Figs. 6 and 7 and it may be found that such substitution would make for increased smoothness in the operating of the apparatus. 7 Thehoops a: are shown in Fig. 3 as held in place in the semicircular bracket or holder 5 by means of suitable clips 6?. Suitablebear ings are provided for the spindles and other moving parts. .The sliding. bar H may be operated in any suitable manner.
holder Z The hinging of the bracket or intended to permit of its being turned up from. the work table when desired. The band drive p" is preferably provided with tension adjuster pfl-and holes 79 are preterably provided in the band 79 to engagecorresponding projections on the wheel 0 r so as to insure a positive drive;
In the slightly modified form of the apparatus illustrated at Figs. 6 and 7, the sprocket wheel 0' is turned when the work holder or hoop is turned, the hoop being attached to the sprocket wheel 0 and i-tsturnmovement is conveyed by the band A to pulley A and from pulley A1 by band A to pulley A and at the same time turning pulley (the pulleys A? and A being fast on a'common spindle A and from the'pulley A by bands and A? a corresponding turning movement of the other hoops is obtained.
The arm (Z and pulley B are in one piece and any turningmovement of the arm d turns the pulley B and by the band B the loose pulley B is turned causing the'bands B" to transmit the movement of the one arm (Z to the other arms (Z.
The arm C and pulley C are in one piece and the turning of the arm C correspondingly turns the pulley C with the result that the bands C transmit the movements of the one arm C to all the other arms C.
Having now fully described my invention, what I claim and desire to secure by Letters'Patent is I v i 1. duplicating attachment for use in connection with sewing machines, compris ing,-in combination, a plurality of pivotally' supported levers, a plurality of work holders pivotally carried by said levers, driving bands connecting saidwork holders to allow oi rotary movements or one being repeated simultaneously by the others, and link mechanism connecting said levers to produce similar longitudinal and transverse movementsofsaid holders.
