SEWING-MACHINE ATTACHMENT.
Specification of Letters Patent.
Patented Mar. 25, 1.919.
Application led August 27` 1917. Serial No. 138,514.
This `invention relates to lubricatingandcooling attachments for sewing machines, such as described in my co-fpending application Serial No. 180,091, filed July 12, 1917,
- and it has for its object to provide certain improvementswhch are embodied in the attachment shown on the accompanying drawing, described in the following specification and pointed out in the appended claims.
On the drawings,-
Figure 1 illustrates, conventionally, a. sew. ing machine provided with my improved lubricating attachment. Fig. 2 illustrates the attachment in elevation looking from the right as shown in Fig. 1, the valve casing being. shown partially in section, and the needle bar being raised.
Fig. 3 represents a front elevation of the same. Y
Fig. 4 represents a plan view thereof.
Fig. 5 represents the attachment with the needle bar in its lowest position.
My improved attachment is illustrated as mounted upon a Singer machine,the latter having the needle bar 10,' the needle 11, the presser bar 12, and the rotatable flanged presser-foot disk 13, the latter coperating with the feed 14. ln this machine the needle bar operates through a'relatively long vertical path,.whereas the presser bar has a short vertical movement, as ordinarily.
My attachment comprises a lubricant or wick holder 15 disposed in the path of the needle and having a through aperture for the passage thereof, and motion-reducing mechanism operated by the imparting a relatively short vertical movement to the holder so as intermittently to lift it from the work to permit the latter to be fed. The holder comprises a tube having one end closed and attened, as shown in Fig. 5, with a needle receiving' aperture 16 through the top and bottom walls thereof. The body of the tube is inclined from the horizontal, but its end is slightly bent so as needle bar for to lie substantially parallel with the bed plate 17 when it is in its lowest position. Within the holder there is an absorbent wick 18 (for the lubricant) preferably consisting of a body of sponge' incased incheesecloth, linen, cotton, or other textile material. Be# tween its ends the holder has an opening 19 into which the lubricant is dropped from a reservoir. Near its outer end the holder is pivotally mounted upon a screw pin 20 which proJects laterally from an ear v21 depending from a supporting plate 22. Said plate is secured by a bolt 23 to a lug 24 which forms a part of the bracket 25 on which the arm 26 for the presser disk 13 is mounted. The bradket is secured to the presser bar 12` so that the plate 22 rises and falls therewith, and consequently the wick holderis moved bodily up and down as the presser bar is reciprocated. ln addition to said bodily movement, however, the wick holder is oscillated about the pivot 20, and, to` secure this movement, I employ a lever 27 pivoted to said plate 22. 'Said lever is pivoted near one end and has a short arm pivotally connected by a link 28 with the outer or rear end of the wick holder, and a long arm pivoted to the lower end of the needle bar. As
'a result of thisA construction and arrange- The lubricant is contained in a reservoir 29 which is cylindrical in shape with' a removable cover 30. Said reservoir issupported bythe plate- 22, and has a communicating valve casing 32,y in which plays a plunger valve 33. The' lower end of the valve casing is directly over the hole 19 to drop the lubricant thereinto when the valve is opened. The valve is reciprocated by a bar 34 pivoted at 35 to the long arm of lever 27, and having an end 36 apertured to receive the end of the valve plunger. A nut 37 on the upper threaded end of said plunger is engaged by the bar, when it reaches a point near its upper limit of movement, and lifted to raise the valve and permit a drop O f lubricant to fall into the wick holder.
The details of the -construction which I have herein described may be varied con# arranged in the path of the needle, and
means for connecting the said holder to the needle bar for moving said holder-in lines longitudinal of the path of the needle.
2. Anl attachment for sewin machmes,
comprising a lubricant holder a apted tov be arranged in the path 'of the needle, and having a through aperature for the needle,
means for pivotally supporting said holder,
and means for connecting said holder with the needle bar whereby lated by the needle bar.
3. An attachment for sewing machines, comprising a lubricant holder adapted to -be arranged inthe path of the needle and having a through aperture for the-needle, means for pivotally supporting said holder upon said holder isoscilthe presser bar, and means for connecting said holder with'the needle bar.
4. Asewing machine comprising a needle, a-needle bar, and a presser bar, in combina'- tion with a lubricant holder having-an end located below'- the needle bar ,and arranged to supply lubricant to the needle, means for movably supporting said holder, and motionplate, a needle and aneedle reducmg means connected to the holder and to the needle bar, -by Awhich the holder is moved with the needle toward and l-from the work but through a shorter path of movement.
5. sewing machine comprising a needle, a needle bar, anda presser bar, in'combination with a lubricant holder having an end located below the needle bar and arranged to supply lubricant to the needle, a support connected to the machine, a pivot for pivotally connecting'said'holder to the support, and anoperative connection between the holder and the needle bar by which said end of the'holder is caused to move in approxi- V mate parallelism with the needle.
. 6. A sewing machine comprising a needle,
a needle bar, and a presser bar, in combinal tion with a lubricant holder having an end located below the needle bar and arranged to supply lubricant to the needle, a support connected to the presser bar, a pivot member connecting the holder to the support, and an plate, Va needle and a needle v and the needle bar,
operating lever to the` needle bar and holder to cause the said 'end of the holder to reciprocate in approm'mate parallelism with the needle.'
7. A sewing machine comprisingv a'needle, a needle bar, and a presser bar, m-combmav .tion with a lubricant holder having an end located below the needle bar and arranged to supply lubricant to the needle, a support connected to the presser bar, a plvot mem" berV connecting the holder to the support, an operating lever pivoted to said support, a
pivot connecting the lever to the needle bar,
and a linkl connecting the lever and the holder. Y
8. A sewing machine comprising the com'- 'l bination with thestitch-forming mechanismand the presser-foot mechanism, of a lubricant holder pivotally supported by. the i presser-foot mechanism and ated by the stitch-forming mechanism, said lubricant holder having a portion 'which supplies lubricant to the needle and `which is movable in a path: approximately parallel .to-
