Specification of Letters Patent.

Patent ed Feb. 24, 1914.

Application filed may 3, 1913. Serial No. 765,212.

To all whom it may concern Be it known that we, lfinaxluan A. RJ-IEUE, a citizen of the United States, residing at Manchester, county 01 Essex, St te of Massachusetts, and Jonn Kinwioz, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Sewing-Machines, of which the following description, in connection with the accompanying drawing, is a specification, lik'echaraeters on the drawing representing like parts.

'This invention relates to sewing machines and has for-one of its objects to ,provide a novel and simple mechanism for operating the shuttle whereby the number of parts is reduced r ad a construction is provided which enables the machine to run at a high speed without vibration.

\Vhile our invention is applicable to various types of sewing machines, it is part-icularly applicable to machines of thatv type in which the needle is sustained by a needle bar that operates in a horizontal plane beneath the bed frame of the machine, as is usually done in a socalled finisher machine, and, therefore, we have illustrated the invention as it would be applied to a machine of this type.

In order to give a specific illustrationof the invention, we have chosen to show it as it would be applied to a finisher machine of thetype shown in patent to Kiewicz, N 0. 1,047,537, dated December 17, 1912. We wish to state, however, that the invention is not limited to use in this particular type of machine.

' Referring now to the drawings, Figure 1 is a side view of a finishing machine such as shown in said Kiewicz Patent No. 1,047,537, with a portion broken out to illustrate thein'vention; Fig. 2 is an endview of the bed plate with a part broken out to illustrate the invention; Fig. 3 is a section on the line a'--m, Fig. 2; Fig. 4 is an under side view of the machine.

"QWehave shown at 1 the bed plate of the machine beneath which is journaled the usual driving shaft 2 by which the parts are driven, said shaft being operated from a loose pulley 3 thereon by suitable clutch mechanism designated generally by 4 which ilt will not be necessary to describe at all in etai l The needle 5 is secured to a needle bar 6 which reciprocatesin a swinging frame 7 that is given its lateral movement by means of the connection 8 operated from the switch cam 12 on the main shaft 2, as'usual in mament for the operation of the stitches by the switch cam 12.

Finishing machines of the above-described type have as a part thereof benders for forming bends in the work, thus enabling blind. stitches to be formed. The bender is shown at 13 andis mounted on a swinging arm 14 which is illustrated as pivoted to the frame at 15 and is given its vibrating movement by means of a cam on the main shaft 2, all as illustrated in said Patent No. 1,047,537.

300 is a resser-foot carried bya vibratin arm 31 also pivoted to the frame at'15, sai

arm having an extension 32 which cooperates with the clutch mechanism. in such a way that when the clutch is released the presser-foot is elevated. This feature is also illustrated and described in the aforesaid I patent.

Cooperating with the needle in the operation of forming the stitch is a shuttle, as usual in sewing machines of this type, said shuttle not being shown herein as it forms no part of our invention. This shuttle is sustained by an oscillatory shuttle carrier which is mounted to turn in a block 18 secured beneath the bed plate and which is provided with a depending shaft or pin 19 carrying at its lower end an arm 48 provided with a stud 47 playing in a slot 46 of an oscillatory member -14 which is pivoted at 45.

The parts thus far described are or may be substantially as shown in the aforesaid patent, and as the operation will be readily understood, no further description thereof is deemed to be necessary 1 In our present invention we provide a simple and novel mechanism for operating the shuttle which consists of means for connecting the oscillatory member 44 directly to the needle bar, so that the'reciprocations of the needle bar are transmitted directly to the shuttle carrier and thus to the shuttle. We accomplish this end herein by providing the pin 11 to which the actuating link is secured with an extension QOand which'is received in an aperture in the end: 21 of a link or connecting member 22, the other end of which is pivotally connected'to the oscillatory member d4, as shown at 23. The pin or projection 11 is provided with a guiding flange 24, the upper edge of which is received in a groove 25 formed in the I under side of a guiding member 26 secured to: the bed plate, guiding flange 24 7 serving to maintain the pin 11, and conse- Lquently the end of the connecting member 10, in a right line. It will be remembered thatthe needle bar has a lateral movement,

and this lateral movement is permitted by a sliding connection between the block 130 and the pin IL The projection 20 is shown as provided with a head 30 which is receivcd bchindguiding lips-33 secured to the end will-13s of the bed frame, said guiding lips acting in conjunction with the guiding fiange ,2-1- and groove 25 1n holding the parts in a correct right line during their re cip rocatingg movement. With this construction it will be noted that there is a direct and single connection between the pin ll by which the needlebar is actuated and the oscillatory member 44, this single connection comprising simply the link 22. i The, shuttle is, therefore, directly operated from,

the needle-har-actuating mechanism and no separatedevlce or set of devices for actuat: ing the shuttle irom the main shaft 2 s required, as is illustrated in the before-mon tioned patent. This construction reduces the number of parts in the machine materially and provides a construction which can be operated at high speed without any inconvenience;

While, we have illustrated herein one embodiment of our invention, We do not wish tobe limited to the constructional features shown.

Having fully described our invention,

what we claim as new and desire to secure by Letters Patent 1s:

1. In a sew1ngmach1ne, the combination with a bed plate frame, of a horizontallyreoiprocating needle-bar beneathzsaid bed plate, a pin extending laterally from th needle bar, means on the frame fr *ming a ,guidejfor; the end of the pin,'actuatii mechanism connected to said pin for aetutitmg the needle bar, a shuttle carrier, and

means connected to said pin for actuating the, shuttle carrier. ,1

2. In a sewing machine, the combination with a bed plate frame, of a horizontally- -reciprocating needle-bar ben ath said bed plate, a pin extending latera ly from said needle-bar, guid ng means on the frame for recelvmg and gu dingthe end of the pin, a

driving shaft, a connecting rod connecting Sflld shaft and pm, a shuttle carrier, an oscillatory member connectedthereto, a link connecting said oscillatory me1 nber to said pin, the latter havmga, gtudmg flange thereon betweenf said link and connecting rod, andthe bed frame having a guldlng groove to receive said flange.
