SEWING-MACHINE.
Specification of Letters Patent.
Patented Nov. 1o, 1914.
Application filed February 8, 1913. Serial No. 747,035.
T0 all whom it may concern:
Be it known that I, JOHN C. RINGE, a citizen of the United States, residing at Stratford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to improvements in sewing machines, and has for its objectto automatically'disengage a driven shaft from the control of its driving mechanism when, from any-cause, the actuation of the driven shaft is accidentally interrupted.
When operating sewing machines employing a loop-taker which rotates or oscillates in a guideway, or a loop-taker provided with an internal groove in which is journaled the flange forming the periphery of a bobbincase held against axial movement, as is common to the construction of many varieties of sewing machines, it frequently occurs that a short length of sewing thread or small cuttingof the fabric being acted upon is carried into the guideway or groove, with the result that the machine is suddenly brought to rest, and when employing belt or gear connections for connecting the main and looptaker-actuating shafts, as distinguished from crank connections, the sudden stopping of the machine frequently causes one or more of the teeth of the gear members to be broken oli", or the belt is subjected to undue strain and often broken or otherwise damaged. i
Referring to the drawings, Figure 1 is a view in front side elevation of one variety of commercial sewing machine, a portion of the bracket arm and bed-plate being broken out to better illustrate the application of' the invention, Fig. 2 a vertical central section of the shaft-disengaging mechanism and lower belt-pulley, together with a portion of the loop-taker-actuating shaft, and Fig, 3 a detail, in perspective, of the shaft-disengaging mechanism.
As the invention has to do only with the transmission of power from the supply to the stitch-forming mechanism, only such reference will be made to the well-known parts of the sewing machine as is deemed necessary for a proper understanding of the invention.
Referring to the figures, 1 represents the bed-'plate o f the sewin g machine upon which 1s mounted a bracket arm comprising the arm standard 2 and arm bracket 3, 4 the main or needle-bar-driving shaft provided with a belt-pulley 5, 6 the needle-bar, 7 the cloth-presser, 8 the cloth-presser bar, 9 the take-up and 10 the feed-dog. As the means herein employed for giving feed movements tothe feed-dog are common to sewing machines of the present variety, further reference thereto is deemed unnecessary.
11 represents the loop -takeractuating shaft, l2 a belt-pulley carried by the main shaft, 13 a like pulley mounted upon the shaft 11 to rotate with or independently of said shaft, and 14 a belt connection for operatively connecting said main shaft with said loop-taker-actuating shaft, and as said pulleys are of the ratio of two to one, the shaft 11 is given two rotations to one rotation of said main shaft.
15 represents a clutch disk provided with a hub 16 and secured on the shaft 11 by suitable screws, as 17,.and to the faceof said disk are secured by screws, as 18, pawl members 19 and 20 which coact with a stud 21 provided with a roller 22, for a pur ose later to be explained, said pawls being eld in effective relationship with said stud and roller by suitable springs, as 23, secured by screws, as 24, to the clutch disk 15.
25 represents a loop-taker provided with a bobbin-case 26 and a downwardly extended loop-taker shaft 27 provided with a spiral gear 28 (teeth not shown) corresponding to the gear 29 carried by the shaft 11. As the present loop-taker and bobbin-case are common to many varieties of commercial sewing machines (the present variety being substantially such as that represented by United States patent to Dial & Dimond, No. 578,136, dated March 2, 1897), it has not been thought necessary to further describe the relative action of these parts.
In the operation of the machine, the pawls 19 and l20 coact with the stud, 21k carrying the roller 22 to transmit power from the main shaft to the loop-taker 25, but should the effective action of the shaft 11 or parts driven by it be accidentally resisted, the pawls will yield and allow the pulley 13 to be rotated independently of said shaft, thus protecting the connection (in the present instance, the belt 14) from injury through any accidental resistance offered the elements driven by said pulley.
lVhile it is preferable to locate the shaftdisengaging mechanism at a point of comparatively slight resistance, it is to be understood that such mechanism might be combined with the shaft 4 and pulley 12, or interposed between the band wheel 5 and main shaft 4, but as the difliculties most commonly experienced in connection with the operation of sewing machines are due to accidental interference with the effective action of the loop-taker, it is desirable to locate the shaft-disengaging mechanism as close to the loop-taker as is practicable.
l. In a sewing machine, the combination with stitch-forming mechanism including a needle, a needle-carrying bar and a looptaker, of means for actuating said needle and loop-taker to form stitches including automatically controlled means for interrupting the action ofsaid loop-taker independently of the movements of the needle-carrying bar, when, from any cause, the stitch-forming movements of the loop-taker are accidentally opposed.
2. In a sewing machine, the combination with stitch-forming mechanism including a needle, a needle-carrying bar, a needlebar-actuating shaft, a loop-taker and a looptaker actuating shaft, of connections for operatively connecting said shafts including means controlled to interrupt the transmission of power between said needle-bar-actuating shaft and said loop-taker independently of the movements of said needle-carrying bar when, from any cause, the stitchforming movements of the loop-taker are accidentally opposed.
3. In a sewing machine,'the combination with stitch-forming mechanism including a needlez a needle-carrying bar, a needle-baractuatmg shaft, a loop-taker and a looptaker-actuating shaft, of connections for operatively connecting said shafts including means mounted on said loop-taker-actuating shaft and controlled to interrupt the transmission of power between said needle-bar actuatin and loop taker actuating shafts indepen ently of the movements of said needle-bar actuating shaft when, from any cause, the stitch-forming movements of said loop-taker are accidentally opposed.
4. In a sewing machine, the combination with stitch-forming mechanism including a needle, a needle-carrying bar, a needle-baractuating shaft, a loop-taker and a looptaker-actuating shaft, of connections for operatively connecting said shafts including a power-transmitting member mounted on said loop-taker-actuating shaft and provided with a stud for coacting with suitable pawls carried by said loop-taker-actuating shaft, said pawls being controlled to interrupt the transmission of power between said needle-bar-actuating and loop-taker-actuating shafts independently of the movements of said needle-bar actuating shaft when, from any cause, the stitch-forming movements of said-loop-taker are accidentally opposed.
In testimony whereof, I have-signed my name to this specification, in the presence of two subscribing witnesses.
JOHN C. RINGE.
