SEWING-MACHINE.
Specification of Letters Patent.
Patented Mar. 18,1913.
1/ c all whom it may concern 3e it known that I, JOHN C. HINGE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sewinglvlachines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invent-ion relates to improvements in multiple needle sewing machines, and has for its objectto provide improved meansfor.
transmitting power from the main shaft to the loop-takers, and togfacilitate the adjustment of the needles and loop-takers when changing the distance between the seams.
, In the earlier constructions of multiple needle sewing machines, power is transmitted to the complemental loop-takers through a single connection leading from the main shaft and, accordingly, the efiective action of the loop-takers with respect to' their coacting needles is, to a substantial degree, dependent upon this one connection.
In the present construction, each looptaker is provided with an independent train of connections leading from the main shaft, making it convenient to adjust any element of either of said trains without in any way interfering with the relative action of the other elements comprising said trains.
In a two-needle sewing machine the adjustments most important to accuracy and convenience are those for changing the gage of the stitch-forming mechanism, which consist in first changing the gage of the needles by substituting a needle-holder of the required gage, followed by adjusting the looptakers to correspond to the gage of the needies, and as'the efficiency of the sewing machine depends upon maintaining the given relationship of the loop-takers and the r .coacting needles when changin from one to another gage, the means for e decting the adjustment of the loop-takers becomes an portant factor in the practical application of the machine. In the present construction, when it is desired to efiect a change'in'the gage of th loop-takers, the o orator loosens the hook-saddles from the be plate and the heir res ective shafts, and moves the'latter endwise t rough said belt-driven pulleys a-distance suflicient t effect the desired adjustment of the looptakers,.then the operator secures said hooksaddles and driven pulleys in their proper positions, such adjustments being effected without in any way endangering a change in the driving relationship of the elements comprising the separate trains of connections. Further, the strain upon the looperactuating elements, instead of falling upon a single train of connections, as heretofore, is equally distributed between said complemental trains; and that this last mentioned advantage is extremely important will be readily understood by those versed in the art of sewing machine constructions whose experiences have made them acquainted with the many different constructions calculated to overcome the strain incident to the transmission of power between elements subject to a sudden starting and stopping, as in the operation of sewing machines driven by power. l
In describing the present improvements, only such limited reference will be made to the usual well-known parts of the sewing machine as is deemed necessary for a proper understanding of the invention.
In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a view in front side elevation of a sewing machine equipped with the present invention, the bracket arm and bed-plate be: ing broken out to better illustrate the'detail's in construction. Fig. 2 is an underside view of the bed-plate shown in Fig. 1. Fig. 3 is a vertical cross section through the arm bracket standard and bed-plate, looking toward the front end of the machine.
" Referring to the figures, 1 represents the bed-plate of the sewing machine upon which is mounted the bracket arm comprising the arm bracket 2 and standard 3, 4 the main or -needle-bar-driving shaft carrying at one end the hand or band wheel 5 and at its opposite end operatively connected with the needle-carryin bar 6 through the commonly employed sha flange and link connection (not shown), 7 and 8 needle-thread tensions, 9 the needle-thread take-up and 9 the needle-holding bracket secured upon the lower end of said needle-bar.
,10 represents the feed roc shaft connected at its forward end throu h-the commonly employed arm and inte screws (not shown) with the feedtag-carrying bar 11,
tilt
t be moved endwise, each oi; till elements comof which embraces the usual feed-eccentric l (not shown) carried by the main shaft l.
13 represents the feed-lift rocleshaft which, at its forward end, is connected by collar 1 t, arm 15 and slide block 16 With said feed-dog'carrying bar and at its opposite end, by a connection 17, with the feedlift eccentric connection 18 Whose upper end. embraces the commonly employed feed-lift eccentric not shown) also carried by said main shaft.
l9 and 20 represent vertically mounted left and right hand loop-taker shafts, res ively, each of which carries at its upper end its respective loop-taker 19 and. 21"", said shafts being mounted to rotate in suitable bearings formed in the respectire'hooksaddles E21 and adjustably secured by screws, as to the underside of ihe'bedplate 1, spiral gears Qet and 25 carried by the espective loop taker shafts acting to connect the latter with their respective driving shafts, referred to hereinafter.
All of the fore ing parts are usually found in sewing '1 ines of the present class, and are herein shown as best repre senting one from of construction to which the present invention is applicable.
represents a loop-taker-driving shaft mounted in suitable hearings formed at the underside of the be l-plate, connected at its forward end by a spiral gear 2'? With the spiral gear 25 carried by the loop-taker shaft 20, andjt rovided at its opposite end Wit-l1 a belt-pulley 28 secured by screws, as 28, and held against rotation independent of said shaft by key 28 and lceyvvay, as 20 and driven by a belt 29 actuated from a belt-pulley 30 carried by the main shaft. 31 represents a second loop-talrer-driving shaft mounted in the manner of shaft 26, connected at its forward end by a spiral gear with a spiral gear 241 carried by the loop-taker shaft 19 and provided at its 0pposite end With a belhpulley 33 (compleiental to the pulley 28) secured by screws, as and held against rotation independ ent of said shaft by key 33 and keyWays, as 1.9 and driven by a belt 34: (complemental to the belt 99) actuated,=from a belt pulley 35 carried by said main'shaft. Each of the loop-taker shafts 19 and 20 is operati'vely connected with the main shaft by an inde ndent train of connections. The shat are provided With the're snecti e d 87 secured as 38, to hold sai by screws, shafts against endwise mo emei'i s in the bearings 39 and d0 When said shafts are free to be moved endWise through their respective pulleys 28 and 33. From the foregoing it is to be understood that when the heel; saddles are free to be adjusted and the vloop-talrer shafts free to prising the separate trains of loop-taker connections are held against stitch-forming movements independent of the remaining elements, and this is accomplished by the employment of a suitable key and coacting keyivays for operatively connertine said lOOp-l'tlliGl' shafts with either a driving or driven element carried thereby, the pre-.
ferred form of construction being to place said sliding connection between said shafts and their respective belt-driven pulleys, as in the machine of the application,
