STOPPING MECHANISM FOR SEWING-MACHINES.
SPECIFICATION forming att r Letters Patent No. 680,665, dated August 13, 1901. Original application filed April 4, 1900, Serial No. 11,495. Divided and this application filed August 16, 1900. Serial No.
27,111. (No model.)
To ctZZruhom it may aorwern:
Be it known that I, DONALD NOBLE, a subject'of the Queen of Great Britain, residing at Finsbury, London, England, have invented a certain new and useful Improvementin Stopping Mechanisms for Sewing-Machines, of which the following is a full, clear, and
exact description.
This invention relates especially to stop IO ping mechanism, or, asitis familiarlytermed,
a stop-motion for sewing-machines; andv the subject of this case is divided out of my application for patent for eyelet-sewing machines, filed April 4, 1900, Serial No. 11,495,"
in accordance with the requirement of the Patent Office.
The inventioncomprises a stop-motion in be stopped. In connection with such a stopmotion Iemployan emergency stop by which the machine may be brought toa'stop irrespective of the state of 'completion'of the 2 5 cycle of movements, so that in case of break age of the thread or such other difficulties, the operator may stop the stitching instantly, all as I will proceed now more particularly to set forth and finally claim.
In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, lligure 1 is a front elevation, partly in section, of parts of the well-known Wheeler &Wilson sewing- 3 5 machine equipped with my improvements.
Fig. 2 is a section taken in the plane of the line a ct of Fig. 1. Fig. 3 is a side' elevation of the right-hand end of the sewing-machine. Fig. 4 is a detail elevation of the brake-lever or emergency stop'used in connection with the stop-motion and counting mechanism,
wherebythe movements of-the machine may be arrested, the'needle-vibrating mechanism being omitted.
The stop-motion device and the counting mechanism, herein in. part shown and which may be employed in this machine, form the subjects of Patents Nos. 656,852 and 656,853,
dated August 28, 1900, and therefore only such limited reference will be made to these parts as is deemed necessary to a proper understanding of my present invention. Also the stitch-forming mechanism employed may be and so far as shown is of the usual construction found in the well-known Wheeler '& Wilson machine, having a horizontally-vibrating needle-bar, with the exception of the mechanism for imparting the horizontal vibration to the needle-bar.
. The bed-plate a, overhanging arm I), main 6o shaft 6, loop-taker d, needle-operating shaft 6, and the pitmen connecting the said two shafts may be of the usual Wheeler 8: Wilson construction. The needle-bar is arranged in vertical bearings in a vibrating gate, and has a vertically-reciprocatin g motion imparted to it, all in any usual Way. The vibrating mechanism may be of any approved construction, but is here shown as of the particular construction set forth in application Serial No. 11,495, hereinbefore'referred to.
The clutch mechanism herein shown is the same as that shown in my Patent No. 656,853, before referred to, and comprises the combined fly-wheel and hand-wheel f, having a friction-ring g, of leather, metal, or other suitable material, applied thereto. his a movable clutch-disk arranged within a recess within the fly-wheel and having headed bolts or rods t' applied'thereto, and these bolts or rods extend through the friction-ring and through the clutch-disk j, also arranged within the. recess in the fly-wheel and having a sleeve is, which encircles the shaft 9 and upon which sleeve the fly-wheel turns freely, said sleeve being rigidly secured to the shaft 6. Springs Z are interposed between the heads of the bolts or rods and the clutch-disk j and normally tend to draw the clutch-disk it into contact withthefriction-ringg. Mountedloosely upon abearing m, projecting from the arm of the machine, is abrake-disk at, having a series of inclines on its left-hand face, which cooperate with similar inclines on the right-hand face of the disk 0, which is likewise loosely mounted upon the bearing m, and this lasti the end of the horizontal shaft 9.
mentioned disk 0 has an arm 19, which is adjustably secured by the screw q to the arm of the machine. Interposed between the brake disk n and the clutch-diskj is a brake-ring a, seated in a recess in the clutch-diskj. In Fig. 1 this clutch mechanism is shown in the released position, which position is effected by a movement of the brake-disk it against the heads of the bolts or rods 2', which moves them toward the right, and thus releases the clutch-disk h from engagement with the friction-ring g, and subsequently the brake-disk '22 comes into contact with the brake-ring r, and thus accomplishes the stopping of the needle-bar shaft. Any other clutch mechanism having this capacity of motion may be substituted for the clutch mechanism described.
The feed mechanism herein shown is the same as in my case, Serial No. 11,495, referred to, and forms the subject of a divisional application thereof, filed July 14, 1900, Serial No. 23,639, and so far as shown comprises the rotary circular feed-disk 4, journaled within the plate 5.
7 is a bevel-gear which is secured concentrically to the under side of the feed-disk 4 and meshes with a beveled pinion 8, fast on The shaft 9 is suitably journaled within the bed-plate, and tight on the other end thereof is a pinion 10, which meshes with a gear-wheel 11, secured upon a horizontal counter-shaft 12, journaled within the base of the arm b. Upon the outer extremity of the counter-shaft 12 is secured a pinion 13, which meshes with and is driven by a large gear-Wheel 14, carried by the stopping-disk 15 of the counting mechanism. The stopping-disk 15 receives an intermittent rotation through the clutch H,a segmentlever 59, connected therewith, eccentric 55on end of shaft 0, and connection 56 between said eccentric and segment-lever, as shown and described in my Patent No. 656,852. Thus it will be clear that the circular disk 4 receives its feed movements from the intermittent rotary movement of the stopping-disk 15 through an intermediate train of gearingto wit, gears 7, S, 10, 11, 13, and 14, and shafts 9 and 12.
The feed-disk 4 has a central circular opening 1.6, within which extends the circular throat-plate 17, provided with the usual needle-aperture 18 and a spur 19. The bevelgear 7, secured to the under side of the feeddisk 4, has a central opening 20 to receive the circular throat-plate. D The throat-plate 17 incloses the bevel-gear 7 and is supported in position bymeans ofscrews 21, (only one shown,) tapped in theunder side of the plate 5, Fig. 1.
22 is a cloth-clamp, secured to and supported in position by a circular table or ring 23-, which is journaled around the feed-disk 4 in such manner as to be capable of turning or swinging freely around said disk.
24 is a washer interposed between: plate 5 and table 23 and disk 4. V 7
30 is a post whose upper end passes through a perforation 31 in the clamp 22, and pivoted ,to the upper end of said post is a cam-lever to the usual brake-lever.
Referring to Figs. 2 and 4, is a spring held lever or dog pivoted to the lower end of the usual brake-lever 71 and adapted to cooperate with the stopping-disk 15 at the will of the operator. 72 is a shoulder or stop on the lever 71, whereby the downward movement of the inner end or nose 73 of said lever is limited. The position shown in full lines in Fig. 4 is that which these parts occupy when the machine has been stopped, while the dotted lines in this view illustrate the position'assumed by said parts when the machine is running. The effect of the lever 70 is to permit the brake-lever 71 to be operated manually at any time to stop or start the machine irrespective of the relative position or time of the counting-disk,- and this stopping is effected by throwing the emergency-lever 70 against disk 15, so as to project the upper end 75 of said brake-lever within the field of travel of the cam 74. (Shown in dotted lines in Fig. 2.) The reverse movement of the lever 70 takes the upper end 75 of the brake lever out of the field of travel of said cam 74.
What I claim is- 1. A stopping mechanism for sewing-ma chines, comprising a stopping-disk, a brakelever, and an emergency lever or dog carried by said brake-lever and interposed between said brake-lever and stopping-disk, whereby the machine may be brought to a stop irrespective of the state of completion of its cycle of movements, combined with means for forming stitches and means for controlling the number of stitches to be made, substantially as described.
2. In an automatic stop-motion mechanism, the combination of stitch-counting mechanism, a stop-motion mechanism including a brake-lever, and an emergency lever or dog carried by said brake-leverand interposed between said brake-lever and counting mechanism, whereby the machine may be brought to a stop irrespective of the completion of the full cycle of movements, substantially as set forth.
3. In an automatic stop-motion mechanism, the combination of stitch-counting mechanism, a stopping-disk, a stop-motion mechanism including a brake-lever, and an emer- In testimony whereof I have hereunto set my hand this 15th day of August, A. D. 1900. 10
