Y.Application filed February 12, i826.
Be it known that l, Eno-An C. ltirsoN, a citizen ot the United States, residing at Handley, in the county ot liana-Wha and State of lVest Virginia, iave invented certain nevvv and useful improvements in Sewing-laohines; and l do declare the following' to be a full, clear, and exact description of the invention, suoli as Will enable others skilled in the art to which it appeitains to niale and use the saine.
rllhis invention relates to improvements in inultiple needle sei-,ving-inachines, and has inore particular reference to a` machine of this class wherein novel ineans is employed and associated with the needle-bars in such a inannei that they inay be operated siinuitaneously or independently, that is, both ot the needle-bars niay be operated the sanie tinie to torni double row et stitching, or one oi theinniay be made inoperative and only a. single needle-bar perniit ed to operate when it is desired forni only a single rouv oi' stitching.
= lie object ot this invention is to iniprove upon the construction for cx'ii'cyinp3v out 'the above mentioned principles ot operation, by the provision ot a sini-ely constructed device which is extremely inexpensive to inanufaotui'e, yet equally :is etlicient in use as incre intricate and expensive devices tor bringing' about the saine result.
Uther objects and advantages oi invention will be apparent during the course ot the 'following description.
ln the accompanying' di'. a part ot this speciiic J on anu in v numerals are employed pai-ts through the saine:
Figure i is a sectional raginenta v view ot a portion of a conventional type oi niachine-head, equipped With iny improved inechanisni, the needle-bars being` shown connected together tor simultaneous operation. i
Fig. 2 is a View like Fig. l, disclosing the rela-tive position of the needle-bars when one of them is inoperative.
Fig. 3 is a section on the line 33 ot Fig. l.
ln carrying out my invention l employ a drive-shaft which is associated With the needle-bars and is adapted to reciprocate the latter in the usual manner, said shaft including a. crank-portion, which is coinforming iiclililie to designate lilie plane ot the Specification of Letters atent.

posed et .disconnectible sections, each of which carries and actuates one of the needlebars.
Y ,J c e nead which inay be oit any suitable construction, being preferably formed in a manner siniilante that shouf'n. The numerals 2 and 3 indicate apair or needle-bars, which are reciprocated through the action of a driveshait el which coacts with them; This drives'haift includes a crank-portion 5, Which Consists of separable parts provided with crankpins 6 and 7, the lattei1 being carried by a rotatable nieniher which is journaled in the head i, While the former is supported in any suitable inanner and rotated by suii'gable ineans. rllhese crank-pins 6 and 7 are readily disconnectible, 'so that the cra-nlpin h which carries the needle-bar 3 niav be operated independent ot the crank-pinU 7 which carries needle-bar 2, when it is desired to forni a single line oft stitching. These cranlipins are connected together for simultaneous operation by nieans or" a ineinber preferably in the :torni ot a screwT 8 which entends through the crank-pin 7 and L1 A l has threaded engagement with a socket 9 formed in the crank-pin 6. The entrance to the threaded socket 9 is enlarged as indicated 10 to permit the separable parts 6 and 7 to be more readily rconnected together. ln other Words, the socket 9 is enlarged at this point to perinit the screw 8 toghe inore easily and readily engaged with said socket. Emphasis is to be laid on the tact that the scr-euT S is et length to permit it to extend into au openingll in the head when the needle-bar 2 is inoperative.
't shown and described an openh the head oit the screw 8 is c when the needle-bar 2 is out ot y desire it to be understood that any other means may be employed for this purpose, such for instance, a shoulder may be provided with which the head of the screw e engaged. ien it is desired to torni a double ioW et' stitching, the needle-bars will be connected together 'for operation in the manner discloced ,in Fig. i. It it is desired non7 to torni single row oi" stitching only, the needle-bai' 2 may be quickly and easily put out ot use. To accomplish this, the hand- Wheel, by means of Which the drive-shaft l is rotated, will be turned until the lower ends ot both of the needle-bars are substantially even, or assume a position approximately like that shown in Fig. 1. lVhen in this position, a screw-driver may be inserted through the opening 11, and engaged with the kerl'l in the head of the screw 8. New, by rotating this screw in the usualnianner, the crank-pin' 6 ot the shaft carrying the needle-bar 3 will be disconnected from the crank-pin 7, and the head of the screw will have moved in a position to project into the opening il, which position will retain the needle-bar 2 in inoperative position, as disclosed in Fig. 2.
To connect the parts oi the sha'lft'together again for simultaneous operation 'of the needle-bars, the hand-wheel may he rotated until the lower ends ot the needle-bars are substantially even again, whereupon the socket 9 will be in a position to receive the screw 8, and the'parts may be then easily vand quickly connected.
i lVhere the machine is used for simultaneously producing a double line ot stitch-` ing each of the needle-bars 2 and 3 will be provided with a needle and suitable thread tensioning devices, `and a pair oit' shuttles will, of course be arranged in the base of the machine to coact with the needles.
By the Jforegoing construct-ion and arrangement ot parts, it will be, seen that either one or Aboth of the needle-bars may be operated. That is, when it is desired to form single line ot stitching only, a single bar may be operated, while. it it is desired to form a double row of stitching both otl the needle-bars may be placed into use.
In Fig. 3 I have shown one ot the needlebars, and.A the manner in which the driveshaft coacts therewith to actuate it. rlhis arrangement consists in tormingthe needlebar with an enlarged port-ion l2 which is provided with a transverse curved slot 13, through which the crank-portion 5 of the drive-shaft extends. Th is or any other suitable construction would equally well serve the purpose. u
Y From the foregoing description taken in connection with the accompanying draw,- ings, it is believed that the operation of my device is entirely obvious, and for this reason, further description is deemed unnecessary. V
I claim: l. ln a multiple needle sewing machine, a support, a rotary shatrjournaled therein and provided at one end ,with a crank-pin,
a member rotatable in said support, its axis of rotation being in almement with that et' the shaft and vit being provided with an crank-pin adapted to aline with the first named crank pin, needle bars carried by said crank pins, and means also carried by one of the crank-pinsV for coupling itwith the other crank-pin to cause both needle bars to operate in unison or one ot them alone.
2, In a multiple needle sewing machine, a support, a rotary shaft journaled therein, being provided at one end with a crank-pin having a socket, a rotaryl member also carried 'by the support, being disposed in alinement .-with said shatt and being provided with a bored crank-pin adapted to `aline with the first Vcrank-pin, a needle bar carried by each of the latter,.and a connecting pin passing through the bore in one ot the crankpins, being receivable in the socket in the Lremaining crank-pin, whereby the needle carried' by one section and engageable with Ythe other section, a portion ot the member being engageable with said shoulder when the sections are disconnected.
5. A multiple needle sewing-machine comprising a casing ha fing an opening' therein, a two-part crank-shattin said easing, one part being journaled therein adjacent said opening, a needle-barcarried by each et the respective parts of thel crank-shalt,v one et' said parts being provided with a horizontal screw-threaded hole extending therethrough, the other part having screwthreaded socket to register with said hole` and a screw extei'iding through said hole and into said socket to imite the parts to cause simultaneous actuation of the needle-bars. Y
said screw being operated through the opening in the casing and being of a length to extend into said opening when the parts et the crank-shaft. are disconnected.
In testimony whereof l have hereunto set my hand and seal. [n s] EDGAR C. MATSON.
