ROBERT BROWN, OF BELFAST, IRELAND.
SEWING-MACHINE FOR FANCY STITCH AND EMBROIDERY WORK.
Specicaton of Letters Patent.
Application filed August 24, 1909.
Patented Mar. *7, 1911.
sei-iai No. 514,433.
To all whom it may concern:
Be it known that I, Bonner Brown, a British subject, residing at Belfast, county of Antrim, Ireland, have invented certain new and useful Improvements in Sewing-Machines for Fancy Stitch and Embroidery IVork, of which the following is a specification.
This invention refers to machines of the type in which embroidery work is done by an oscillating needle bar operated by a cam and lever and is an improvement upon a similar device for which Letters Patent was granted to me July 7, 1908, Number 892,643.
It comprises a re-arrangemcnt and adjustment of `the parts by which the oscillating movement is imparted to the needle bar and the simultaneous reciprocating movement to the shuttle race carrier.
In the construction shown in the patent above mentioned the oscillating mechanism was arranged vertically projecting above the head or frame, and the oscillating lever was connected with the needle bar only through the shuttle carrier mechanism. In my present invention I arrange the oscillating mechanism in a horizontal plane and connect the same to the upper portion ot the needle bar, and not through the shuttle carrier shaft.
The invention will be fully described with reference to the accompanying drawings forming part otl the specification.
Figure l, side elevation partly in longitudinal section of sewing machine constructed in accordance with my invention. Fig. 2, plan of same. Fig. 3, sectional plan showing the cam D and the tension cam N. Fig. 4, transverse section on line .fr- Fig. 1. Fig. 5, transverse section on line g/-y Fig. 1. Fig. 6, perspective diagram showing the relative positions of the parts that constitute the invention.
The main parts of the sewing machine such as the head or frame 1, the base plate 2, the driving shaft 3, the needle bar 4, the needle bar crank 5, the oscillating or swinging needle frame 6 are all of ordinary construction and the shuttle race carrier is mounted on a divided shaft with a coupling thereon to permit of the shuttle race carrier moving to and fro in unison with the needle bar.
The swinging or oscillating frame 6 of the needle bar is operated by a horizontal quadrant lever A pivoted on a pin or stud a secured to a lateral boss or projection on the head or frame l. One member of the quadrant lever A is provided with a bowl or ruuner a which engages with the throw cam D by which the lever is rocked and the other member is formed with a slot a2 in which a pin or stud a3 capable of moving to and fro therein is fitted. rIhe horizontal quadrant lever is connected to the swinging needle frame 6 by a connecting bar or rod B and a second rod or bar C, which are pivoted together by a pin or stud The connecting rod B is mounted to lie horizontally on the top ot' the i'rame and extend the length of the machine and the rod or bar C is forked at one end where it is pivoted to the pin as and at the other is pivoted on the pin b to the connecting rod B.
The throw cam D which actuates the quadrant lever A is mounted on a horizontal stud d in a recess in the back of the frame ot' the machine and is rotated by bevel gear wheels cl cl2 one of which is on the main driving shaft.
To traverse the pin a3 in the slot of the quadrant lever A for the purpose of altering the throw of the needle the bar C is connected by a link e to a horizontal lever E pivoted on a vertical stud e to which lever the desired movement is given by the lever F attached to the end of a vertical spindle Gr, the two levers E and F being connected by a link y. The spindle G is rotated in one direction by the nger or arm g against the pressure of the sprino g which rotates it in the reverse direction back to zero. The arm or finger g may be pressed to one side by a knee lever such as K with an arm or member 7c resting against it. Or itmay be connected to a treadle or the vertical spindle G may be otherwise rotated by the operative as the stitch is required to be altered.
The movable shuttle race carrier H on which is mounted the shuttle race is moved to and Jfro synchronously with the needle bar frame by a rocking lever M formed with a vertical spindle or pivot, an upper member m approximately at right angles thereto and a lower member m. The upper member m of the lever M is connected to the rear end of forked quadrant bar C by the pin so that the motion of the quadrant lever A is imparted simultaneously to the needle connecting rod B and the rocking lever M.
The lower member m of the lever M is connected by a link or connecting rod /zto the shaft or spindle 71, of the shuttle race carrier I-I. The movements given to both the needle bar 4C and to the shuttle race carrier I-I are direct from the quadrant lever A and synchronize with one another.
On the main driving shaft 3 between the quadrant lever A and the needle bar 4 a tension release cam N is mounted with a lever n which projects through the side of the frame and bears against the cam to apply and relieve the tension on the thread at the desired time.
The frame l is constructed of a shape to carry these parts or movements and the other parts of the machine are constructed and operated in the ordinary way.
The spindle or shaft lt is constructed substantially as shown in my previous patent and terminates in an angled portion O rocked by loosely engaging a forked arm O carried by a rock shaft Q which is provided with an oppositely extending arm O2 pivoted to a crank arm P, operated from the drive shaft, thereby imparting a suitable rotatory movement to the shaft 7L.
What I claim as my invention and desire to protect by Letters Patent is In a sewing machine of the kind described, the combination with a head and a needle bar having a swinging frame, of a pivoted horizontally arranged quadrant lever, one member of said lever being slotted, a rod arranged in a horizontal plane above the head and pivotally connected at one end to the upper portion of the needle bar, a bar pivotally connected to the opposite end of the rod, a pin carried by the bar for engagement with the lever slot, means for rocking said lever, means for regulating movement of the pin in the lever slot, a shuttle carrier shaft, a vertically arranged rock shaft having upper and lower laterally extending arms and a. rod pivotally connecting the lower arm to the shuttel carrier shaft, the upper arm being pivoted to the bar above mentioned.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN QUINN, G. DUNCAN.
