WAXTH READ SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 256,156, dated April 11, 1882.
Application filed November 21, 1881. (No model.)
To all whom it may concern Beit known that I, HORACE F. Nason, of Natick, in 'the county of Middlesex andState of Massachusetts, have invented certain new and useful Improvements inWax-Thread Sewing-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to certain irnfrovements in the construct-ion and arrangement of the working parts of wax-thread sewing-machines,vwhereb`y such machines are rendered capable of doing irstclass general work at a much higher rate of-speed than has been possible with the machines as heretofore constructed,andisanimprovementin somerespects upon and in others an adaptation of the machine designed by me for special work, and shown and described in Letter'sPatent N o. 227,288, granted to me May 4, 1880, to doing general work, which improvements will be best understood by reference to the description of the drawings andto the claims to be hereinafter given.
Figure 1 is a side elevation of a machine embodying my invention. of the opposite side. Fig. 3 is an elevation of the front end. y Fig. et is a vertical section on line fr w on Fig. 1. Fig. 5 is a vertical section on line y y on Fig. 2, looking toward the front end of the machine. Fig. 6 is a vertical section through thewaX-tank on line z z on Figs. 3 and 4. Figs. 7, 8, 9, 10, 11,12, and 13 are details to be hereinal ter referred to.
A is the frame oi' the machine, upon which are mounted all the workin g parts, said frame vbeing provided with the upwardly-projecting post A', to the upper end of which is secured the worksupporting plate A2, having'formed A in or near its center a suitable opening for the passage of the awl and needle, all in a wellknown manner.
B is the driving-shaft, mounted in bearings in the -frame A, near its base and below the work-supporting plate, and having secured upon its rear end the hand-wheel C and conepulley D, and` upon its front end the crankdisk a, in the front face of which is set the crank-pin c, as shown in Fig. l0. The crankdisk a revolves within 'a recess, b, formed in the frontface of the feed-bar E', near its lower end, as shown in Fig. 3. The recess b has a Fig. 2 is anelevationvertical width just equal to the diameter of the disk a, and a horizontal length equal to the diameter of said disk plus the throw of the eccentric c, which is secured upon the shaft B just in the rear of the feed-bar, and revolves between two anti-friction rolls, c' and c2, which are mounted upon studs set in the rear face of the feed-bar E, as shown in Fig. 9. The feedbar E is pivoted to the front face of the post Al by the pin or stud d, which is adjustably secured in a slot, d', cut through said post, and carries at its front end the T-shaped block c, which fits into a correspondingly-shaped slot, c', formed in the rear side of the feedbar,'as shown in Figs. 2 and 9. The upper and lower walls ot' the recess b are formed by the hardened steel plates f j', secured iu posit-ion, as shown.
rI hc shaft B has also secured thereon the eccentric F, carrying the eccentric-rod F', the upper end of which is jointed to the short arm of the lever G, the opposite end of which is forked to receive the block g, mounted on the h of which works the roll h', mounted upon a y stud set in the back side of the lever G, as a means of imparting to said bar and its looper i the necessary intermittent vibratory motion about the axis of said bar,`said cylinder-cam and its connection'with the lever G being best shown in Figs. ll and 13. y
J is' the presser-foot, slotted to permit the passage of the needle and awl and firmly secured to the lower end of the bar J', which has its bearings in the upper front portion of the frame A, and has secured thereto, between its bearings, the collar J2, from the front side of which projects the arm j, which enters the slot j formed in the cap A on the npperi'ront poras a bearing for the front or movable end of the IOO spring K, the tension of which serves to press the foot J hard upon the work to be sewed.
The presser-foot J is lifted,when desired, by means of the rocker-shaft L, carrying at its front end the lifter-toe L', the movable end ot' which engages with the under side ofthe collar J2, and at its rear end the arm L2, which, when the machine is in working condition, is connected to a treadle, (not sho\vn,) by means of which said shaft L may be partially rotated about its axis in an obvious manner.
M is the needle-bar, mounted in a bearing formed in the feed-bar E, and having secured in its upper end the barbed needle 7c, as shown. Areciprocating motion is imparted to the needle-bar M by means ofthe crank-pin a' and the connecting-rod N, the lower end ofwhich embraces said crank-pin, and the upper end in like manner embraces the pin l, set in the front side of the needle-bar and adapted to move up and down in the slot l' formed in the feed-bar E, as shown in Fig. 3.-
is the cast-oft' bar, having its bearing in the feed-bar E in close proximity to and parupper end the cast-off m, secured thereto, as
, described in my previous patent before cited.
The bar O has secured thereto the pin a, which projects at right angles lthereto through the slot a' formed in the feed-bar E and some little distance beyond the frontface of said feedbar and withinthe sloto formed in a sidewise extension of the connecting-rod N, as shown ward or from cach other, to increase or diminish the length ofthe slot and regulate the time of opcratiugthe cast-off by means of the screws 4o pp, constructed as shown in Fig. 12, and secured in the rod N, so as to revolve freely without endwise movement therein, by pins which pass through said-rod in a position toengage with the circumferential grooves p'p' formed in said screws, as shown.
The looper z is materially improved in form, as compared with the loopers heretofore generally in use, for the purpose of raising the larger portion of it higher above the plane in which the thread is carried around the needle than heretofore,so thatthe operator may more readily see the operation of the sewing as it progresses and detect any imperfection therein. Prior to my invention such loopers have been made with the main body of the looper horizontal, or nearly so, and in the same horizontal plane as the end containing the eye for the thread, which I have found to be very objectionable in doing some kinds of work, and to obviate this objection I make my looper of the form shown in Figs. 7 and 8, with the bendto one side from the vertical shank which en ters the looper-bar, as shown at g, at a point some distance above the level of the plane in which the threadis carried around the needle, and extending it obliquely downward in a straight, or nearly straight, line, as viewed in elevation, to a point within about an eighth ot' an inch (more or less) of its end, as at g', and then giving it a sudden bend downward, as shown in Fig. 8, the eye for the thread passing through said downwardly-bent or lower vertical portion.
Pisthewax-tank,havingacylindricalinterior chamber, a filling-orifice closed by the screwplug P', the nose P2, and mounted upon the stud r set in the frame A. The nose l?2 is chambered or counterbored out to receive the rubber tube s and the screw-tube s', and by the revolution of thelatter the formeris compressed or allowed to expand lengthwise to regulate the friction upon the thread, which passes through said rubber and screw-tubes after being waxed in a wellknown manner. The thread enters the waxtank through the orifice t, the entrance to which is in the upper end of the annular lip surrounding the lling-orilce, and between the end of said lip and the flange of the screw-plug P', so that the thread may have a slight pressure applied to it by screwing down the plug I" upon the rubber packing-ring t' to a greater or less extent, according to the friction desired. The plug P' also serves the purpose of excluding dust and dirt from the wax tank, thus keeping the wax in better-condition than when the tank is open yto the atmosphere, as heretofore practiced.
The presser-foot bar J' has secured thereon the block R, having formed upon one side thereof a series of ratchet-teeth, as shown in Fig. 4.
The awl-bar H has pivoted thereto the pawl u', with its movable end upward, and in position to engage with the teeth on the block R dnrin g the latter part of the upward movement of said awl-bar, and thus lift the presserfoot from the work to permit the Work to be fed by the vibration of the feed-bar and the needle-bar carried thereby. The time of engagement of thepawl u' with the teeth on the block It is determined and regulated by the shield-plate fw, adjustably secured tothe rear side of the cap A3, and projecting therefrom toward the rear of the machine, between the awl-bar and presser-bar, as shown in Figs. 2 and 4.
The cast-off bar O is held stationary at each extreme of its movement till power is applied thereto to move it by the spring-actuated friction-pins w' wf', substantially as described i my prior patent before cited.
What I claim as new, and desire to secure by Letters Patent of the United States, is-
1. The combination, in a wax-thread sewingmachine, ofthe liXed postA', carryingthe worksupporting plate A2, the driving-shaft B, carrying the disk a and eccentric c, and the feedbar E, provided with the recess b and rolls c' and c2, and adjustably piyoted at or near the middle of its length to said post A', and carrying the needle-bar M and cast-off bar O, all arranged and adapted to operate substantially as described.
