TO ALL WHOM IT MAY OONCERN:
y VHei-it known that I, ARCHIBALD C. URARY, of Uticn,v0neida county, New ork,'hnve invented e ncrv' and useful Improvement lin the Mode of Operating Sewing-Machines, y' I The nature of myfinvention consists in attaching tolsewingrnachines a spring or springs for drivingthe same, which spring or springs may be`.woun dup by the weight ofitheoperator pressing upon the 'sent g, and I do hereby declare that the following i-s'n full, clear, and exact `description ofthe construction and operation of the same, reference being had to the accompanying drawings, making a. part of this specication3 in whichf- Figure 1 represents an end view ci" the seat and machinery.
Figure 2; a side view.
- Figure 3, a. view of the 4spring and barrel; and
Figure 4, a. view of the endless screw. f y i The seatioi`- the operator, to which the works are attached, is composed of a bese', A, and the seat propel', A1, and a platform, A2, about half way between them. The seat is raised hyl four spiral springs A3 A3 A:s A3, in which springs are rods Af, extendinginto the tubes'jA5, which tubes rundown to the base, A. When the seat A is pressed down it'restson the tubes, 'On the under side of the seatAl aretwo racks, B B, which extend downwards through th'eplatforiu Aiywhich racks turn two'anged pinions Bl B, attneh'ed to the shaft B2. v On the back sideof the racks, and opposite 4,the piuions BYB, are two friction-rollers B3, also anged to keep the racks steady and up to the pinions. The shaft Bz extends out. beyond the side of theseat, und is supported hy the frame of the machinery. On the ehd of the shaft is the loose wheel C. On each side of C is a. ratchet, C1 and.
C2, and pawlsC3 and The ratchet rand pawl C2 and C* serve to turn the wheel to the right, when the racks are pressed down, land the ratchet and pawl CI and C3 hold the' wheel C while the racks are raised. Gearing into the upper ,side ofthe wheel C is a. pinion, D, on the shaft Dl, and on the other end of D1 is the barrel D2, containing the coiled springD3, forgiving motion to the sewing-machine. Thebarr'el is loose and revolves freely on the shaft,'the spring only being attached to the sha-ft and to the barrel in the usual manner in such cases.
The edge of thebarrel D2 is toothed, :1nd geared initoit is a pinion, E, on the shaft El, at the side of which pinion is the wheel EZ, on said shaft.- Suid wheel `E2 drives a. pinion, F, on the shaft Fl; on which shaft is a wheel, F2; or, instead of a simple wheel, as described, it may combine e. wheel and barrel, containing a. spring similar to D3, in which case the barrel and wheel should-he loose on theshztft, as in the'case of D3. The wheel F2 drives a pinion, G, on the shaft G1, 'on which shaft is the wheel G2, and said wheel Gr2 drives a pinion, H, on the shaft H1, on which shaft H1 is a .wheeh'Hh On the outer end of- IIFisa fan or ily, H3. On the inner end of Hi they he a crank,-'H,.as seen'in figs. -and 2, or other proper means of connecting the machinery'with the sewing-machine. The racks should hev of such length that when pressed down to the tubes they will turn the pinions B1 Bl once around, and-consequently cause the wheel C, by means of the ratchet and pawl C2 and 0*, to revolve once around, while the pinion D should be of such size as to cause the shaft Dl to revolve six times around. When the racks rise, they of course cause the-shaft B1 to revolve backwards, but the wheel C is prevented from `turning with it by means of the ratchet a-nd pawl Cl and C". To prevent the wheel C operating too often, in consequence of the movements of the operator, when once pressed down, the seat may be held down by means of .steps A". Oi' course the number of times the spring may be turned at each pressure upon the seat,
may be varied by changing the proportions of the rocks, pinions, or wheels.v
The operation is apparent from the description already given. On sitting down on thc seat, the weight of the operator presses down the racks B B, which cause the pinions B1 B1 Yto revolve, and they the shaft B2, which .in turn causes the loose wheel C to turn .once around, bymenns of the ratchet and pawl C2 and C4, which wheel C, in turning, causes the pinion D and shaft D1 to turn around six times, and thus wind up the coiled .spring inthe barrel on said shaft. This spring being-wound up, sets the pinion E in motion, and consequently the remainder of the machinery up tothe crank H4' on the last shaft, which being connected withthe sewingmnchine by a Connecting-rod or other proper connection, sets the sewing-machine in motion. The second spring will serve to accommodate the machinery to any shocks but it is not necessary to the perfectionof the machine. The fan or Hy H3 gives steadiness to the motion of themachine. When the operator has pressed the seat down, it may he fastened there with thecatchAs, until it is necessary to wind up the springs-again, when the seat maybe allowed to rise and then againbe pressed down, as described,
In addition to this mode of winding up the springs, or in place of it, the ends of each spring-shaft may bc tted for a key, and be wound up like a watch o1' clock. And in place of either mode, or in addition to it. there may be a, shaft with an endless screw thereon, so arranged as to move on the leaves of ,.-i pinion on the shaft B2, or on the shaft D, which shaft and endless screw may be turned by a. key, as before mentioned, (sr-e iig. 4.) In this way great power may be applied to wind up the spring.
Having thus described my invention, what I claim therein as new, and desire to secure by Letters Patent, is
The herein-describedmode of winding up the spring, by the pressure of the operator on the sent.
