UNITED STATES rArnNT OFFICE..
ALBERT H. DE VCE, OF VESTEIELD, NEW JERSEY, ASVSGNOR TO THE SINGER MANU# FACTURING- COMPANY, A CORPORATION OF NEW JERSEY.
Specification of Letters lPatent.
Patented Feb. 15, 1921.
Original application filed January 27, 1917, Serial No. 144,847. Divided and this application filed .Tune
To all fw lio/m, t may concer/i Be it known that l', Aiinnnfr E. Dn Von, citizen of the United States, residing at Viestiield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in rihreadfiension Supports, oi' which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates broadly to a means for supporting the thread-tensioningl devices of a sewing machine and more particularly to the means for supporting` the tensioning devices tor a teed-oti'p-the-arm inachine, such as that disclosed in my copending` application Serial No. 144,847, filed January 27, 1917, and ci? which this case is a division.
The object oi' the invention is to provide a support for the thread-tensioning` means so located that the tensions are entirely out of theway and do notfinteritere in any way with the operators view of the work-arm, the support also acting to brace the bracketarm of the machine and secure greater rigidity.
in the embodiment shown the machine is carried by a dependingangularly disposed support, at the lower end oi' which is a body portion from which project a bracket-arm and an l-sliaped work-arm, which arms carry stitch-forming mechanism, all as disclosed in my copending application above mentioned. A triangular plate is disposed in the angle between the depending support and the bracket-arm and at one side of the bracketarm and support, said plate carrying a vertical row ot' tensions on its inner face. This arrangement places the tensions out of the way and aliows an unobstructed view of the work-arm during the operation of the machine. The threads are led from the tensions through suitable guides and controlling devices to the stitch-forming mechanism.
In the accompanying drawings, Figure 1 is a side elevation of the machine showing,` the angular plate secured between the depending support and the bracketerm and the tensions carried thereby. Fig. 2 is a horizontal section on the line 2-2 of Fig. l.
Referring to the drawings7 l is' an angularly disposed flattened hollow depending arm the upper end ot which is secured to a Serial No. 241,369.
suitable support and whose lower end e X- tends toward the operator. At its lower end the arm 1 is enlarged laterally to form a body portion 2, irom which extend the upper bracketarm 3 and lower work-arm a. A pulley 5 is mounted on a. shaft 6in the body portion, said pulley being connected by a belt to a drive pulley in the 4upper end oi? the hollow arm l. The `shaft 6 actuates the stitch-torining devices carried by the arms 3 and et, all as ilt'ullyfdisclosed in my eopendingapplication above mentioned. Cast integral with the arm l' and disposed in the angle between said arm and bracketarm 3 is a thin plate or web 7. This plate-is located at one edge et arm 3 and near the edge of the angular arm 4Il. A vertically arranged series o1E tensioning devices 8 is mounted on the inner tace oft plate 7, and due to the offset position of said plate the tension devices are located almost wholly within the recess formed between arms 1 and 3. It will be noted from Fig. 2 that the bracket-arm 3 is itself oit-set with respect to the work-arm 4. and by the above described arrangement ot' the tensions they do not in any way interfere with the operators view of the work. ln addition the danger of the threads becoming;` entangled in the working parts is reduced to a minimum. The threads are led 'from the tensions to the stitch-forming Vmechanism in any desired manner, in the ample shown the upper two threads beingled through a guide 9 and then within the body and to the looper, the next tour threads being,- led through a guide 10 to a take-up mechanism and to the needles, and the bottom thread being led through guides il on the face-plate 12 of the machine to a suitable covering thread mechanism. lt is obvious that the number of tension devices and means' for guiding the thread may be varied to suit conditions.
The plate 7 forms a rigid connection be tween the arms 1 and 3 and thus aids in reducing vibration. n
It is apparent that the thread tensions may be supported in other ways than in the specic manner shown and l thereforev do not wish to be limited other than by the scope of the appended claims.
Having thus set forth the nature of th invention, what I claim herein is 1. In a sewing machine, in combination,
CII
a lframe comprising a iattened depending` support, a bracket-arm carried thereby and.
disposed in angular relation therewith, a work-arm carried by said support, stitchforming mechanism incorporated in saidv frame, a plate supported within the angle formed by said depending support and bracket-arm and a series of tension devices carried by said plate.
Zin a sewing machine7 in combination, a traine comprising a flattened depending "support, a bracket-arm carried thereby and disposed in angular relation therewith, a Workarin carriedby said support, stitchforining Ymechanism incorporated in said frame, a plate disposed in the angle formed by said support and bracket-arm and substantially flush Vwith one side 'face of said flattened support, and 'a series of tension devices-carried by said plate and disposed mainly Vbetween the planes defined bythe opposite side faces of said flattened support.
3. In a sewing machine,-an angularly disposed support, a work-arm extending from said support, a" bracket-arm also extending from said support and spaced troni and lat- -erally ofset VWitli'iespect to said work-arm7 aV web extending between said angular support and bracket-arm` and offset with respect thereto7 andthread-tensioning means mounted on said web,v whereby an vunobstructedrview of the work-arm is obtained. el. ln a sewing machine, a supporting arm,
1,3esi24e said bracket-arm and disposed at Van angle,V
thereto7 thread-tensioning; devices disposed substantially wholly in tliereeess between said support and bracket-arm,V and, means for supporting said tensioning devices.
6. A sewing machine comprising spaced Worlrand bracket-arms, a supporting arin angularly connected Vto said bracket-arm, and means for supporting thieadtensioning devices in the recess between said last-named ai'ins acting as abrace betweenl said arms.
7. A sewing machine comprising spaced VVwork` and bracket-arms, `the latter being oflset, a supporting arni angulaily connected to'saidV bracket-arm, and offset means for supperting thread-tensioning devices in the vrecess between said'last-'nanied arms.
In testimony Vwhereof l liavesigned iny naine to this specification.
