SELF-LUBRICATING DUSTPROOF SEWING-MAGHIN Speccation of Letters Patent.
Application led May 25, 1920. Serial No. 384,027.
'to provide means whereby the bearings of such machines, which are usually high-speed v power driven machines, are automatieal Vor self-lubricating fora long period, for
instance for several days or weeks depending upon the amount of lubricant stored in the machine.
Another object of the machine is the provisiony of means for automatically oilin especially quick moving parts, which coul not be oiled by direct application of the lubricant without the danger of splashing the oil, by means of oil-soaked cotton or waste- Ltape so called fuses saturated with the lubricant.`
A further object of the invention consists in providin a machine of the character specified which can. be oiled by anyone or rather which is self-oilin and needs only the attendance of unskille labor to eilect its lubrication, thus saving expenses for skilled labor.
Other features of my improved machine will become apparent as the description thereof proceeds and will be more fully set forth hereinafter.
With these and other objects in. view my invention consists in the combination and arrangement of parts shown in the accompanying drawings, and particularly pointed out inthe appended claims, it being understood thatchan es in the form, proportion, and minor detalls may be made within the scope of the claims without departing from the spirit or scope of my invention. 6r sacri- .ficing any of the advantages of the invention.

Corresponding parts in the several figures of the drawings are designated by like characters of reference.
The machine frame 10 is provided at one of its sides with the customary operatin wheel 11 secured to operating ,shaft 12 and integrally made with a belt inner' face. cup 14 is provi ed on the side of the frame adapted to. be lfilled with oil or a lubricant in which the customary eccentric 15 and the lower end of excenter bar 16 are moving with the rotating shaft, and the cup is entirely closed against the intrusion of dust and the splashing of oil, a washer 17 being provided on the shaft Vin order to prevent any leaking of the lubricant toward theoutside atl theV placeV where the shaft 12 enters the cup or chamber-14.
The bar 16 and its connections are incased in a dust proof casing 18 which is removably 100 secured to the chamber 14. The casing 18 is pulle 13 on its .i
closed at the top by a plate 19 carrying the v tensioning device 20 and thread guide 21. Within the4 casing 18 the upper end of thebar 16 is secured by the customary Well 10.6
kown split bearing 22 to'theinner end of a wick 24, the other end of which. is un 110 l twisted as at 25and depends into an oil on one side into an oil gage 31, From the shaft 28 an.l oil supplying wick 32 engaging with one end said shaft, vis guided with its other untwisted and branched end 33 into the oil reservoir -26 and is held intermediate its ends to the arm 23 by means of a screw 34.
The arm 23 is provided at its upper edge, intermediate its ends with a thread guiding eye 35 -and the front end of thearm 23 is secured in the ordinary well known manner as at 36, to an operating block 37 secured at 38 tothe movable needle bar 39 intermediate the ends thereof. The needle bar is provided at its upper end ywith an eye 40 for the passage of the threadwhich is ided from the eye 35 to a guide 35 and 1s then guided through a slot' 41 of a bracket 42 secured to the side of an oil cup-or reservoin 43. The thread inal-ly passes through a guide 44 on the end of frame .10 to the needle 45 secured in the ,lower end of the needle bar in the customary well knownmanner. 0
A'thread tenslonmg device 46 basan 1nner projection 47 pressing `the free end oiA a spring 48 againstythe thread guided throu h the slot 41 of the bracket 42, while the ot er end of said spring is secured in the device 46.
A thread tension release arm 49 vis secured to the rear of the arm 23 and is made in two pieces which are adjustably connected at their meeting ends by means of a sleeve 50 integrally made with one of the pieces of arm 49 and provided with a central hole through which the other pieceof the arm is passed as at 51, while a fastening screw 52 is passed through the end of the sleeve into engagement with arm 49 as best seen in Fig. 2. y
The free outer end of'arm 49 is passed through the oil' reservoir 43 in engagement -With spring 48.
Asshown in Fig. 10 the oil cup 43 has an inner oil receptacle 53 and a block 54 provided with passages for the needle bar and the presser bar, and provided with chambers 55 communicating with the passages for the needle and presser bars for the reception of wicks 56, 57 supplying said needle and presser bars with oil.
The presser bar is designated at 58 and stands as customary under the tension of a 5`spring not shown, within the frame 10, the
. bar, the lower end of which carries a -nut 63,
holding the foot with its curved part to the presser bar.
The front -part to provide a passage for the needle 45,while lated b 'ineens of the `foot 62 is cut-awayv a regulating screw 64 adapted to regulate -.the pla-it guard can be locked in its adjusted position by. means of Va lever 65.
',The throat plate 66 is provided with an n opening foi' the passage of theneedle and underneath of lthis opening a lower .stitch forming device 67 (Fig. 5) having anop' ning 681s provided which alsoforms a bear- 69 for the free en-dlof the shaft 12j. p
in an opening in the throat plate 66 underneath Vand below the presser foot 62y a feeding device 70 is arrangedv which can be raised and lowered against the throat lateby Imeans of an adjusting Screw 71 i'gs.-
8 and 9) adapted to raise and lower a carrrierplate 72 to which the feeding device 70 is secured by a screw 73. A screw 74 land plate 75 secure the entire device described before when the parts are'assembled to the outer end of an `arm 76, having a U-shaped member 7 7 adapted to straddle the side wall Y 78 of a` casin or box 79 adapted to be filled closed on top by a cover 80.
with oil an secured upon the side and end walls by means of screws 81. Within this casing the arm 77 4is made integral with a crank body 82 on shaft 12 and its free arm forms part of a rocking frame 83 within'the casing 79. A'stitch regulator of well known construction generally indicated at 84 is. pro videdV at the front part of the machine and comprises a sliding index plate 85 provided with a longitudinal, slot 86 through which the stem of an index finger 87 is extending and secured to the casing or front wall 88 of the oil box 79 is a screw, holding the index plate in frictional engagement with' the wall 88 and having a guide arm 89 for la material guiding plate 90)` while the lower part of the plate 85 is provided with teeth 91 adapted to be engaged by' the teeth of a. gear 93 on the shaft of an operating knob .92 adaptedi to displace theplate in order to regulate the distance of the rows of stitches on each plait. Y
The front plate 88 of the oil reservoir 79'is provided with an cil gage 94 to indicate the level of the oil within box 79. As shown in Figs. 12, 13 and 14 wick holders 95 are provided at the bottom of the box 79 in which Wicks 96 are held by vsprings 97 with their upper ends in engagement with the shaft 12 in order to permanently supply oil tg the same if the level of the oiil con, taifd Within the boxfS has sunk below 'thev level of said shaft.
Intermediate Vtheir ends the pressezV 'oar 58 and the needle bar 39 are guided 'tl-.rough an oil receptacle 98 (Fig/1:) provided with front and rear cu s 99.
" A As shown' in Figs. 5 and 6.the oil receptacle 79 contains thea-ecker frame 83, the lower part of which is rocking on shaft 100. The frame 83 vforms a bearing for a shaft 101 to which isrsecured a sleeve 102 at the end of an arm 103the front part of which is secured to a sleeve 104 on shaft 12. The arm 103 is 4provided with upper openings to receive oi 4 Y Having thus described my invent-ionv what I claim and desire to secure by Letters Patent of the United States is l 1. ,In a` sewing machine ofthe character described, having dust proof, chambered casing including an excenter bary an oil Teceptacle or chamber, a split-bearing forl the excenter bar of the machine having an open-l ing, and a wick adapted to enter the opening in said bar and to extend with itsfree untwisted or branched` ends into said oil chamber, and means for guiding said wick intermediate its ends.
