TREADLE-MOTION- SPECIFICATION forming part of Letters Patent No. 291,200, dated January 1, 1884.
Application filed August 18, 1883. (X0 model.) Patented in Germany February 13, 1853, No 13,339, anrlJuly 27, 1883.
To all whomat may concern.-
Be it known that I, JOHN KAYSER, a subiect of the King of Bavaria, residing at Kaiserslautern, Bavaria, Germany, have invented certain new and useful Improvements in Treadle-Motions; and .I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable oth ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying'drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
In sewing and other small machines operated from a treadle, the oscillations of which are converted into rotary motion communicated to a driving-shaft through the medium of a crank or eccentric and connecting-rod, when the power ceases to be applied to the treadle the weight of the crank and connect ing-rod is usually such as to bring the former at rest on its dead-pointsthat is to say, the
driving mechanism will come to rest with the vertical axes of the rod and crank in the same plane. In order to start the machine, it is necessary to impart by hand a partial rotation to the fiy-wheel before the operator can apply power to the treadle.
' ment of driving mechanism has the further disadvantage of requiring undue exertion on the part of the operator relatively to the power required to drive the mechanism.
The object of this invention is to remedy these disadvantages, as will be fully described hereinafter, and as illustrated in the accompanying drawings, in which- Figure 1 is a sectional elevation, illustrating my improved treadle-motion as applied to a sewing-machine. Figs. 2, 3, and 4 illustrate slight modifications in the construction of said motion.
Like letters of reference'indicate like parts wherever such may occur in the above figures of drawings.
. A indicates the sewing-machine stand, S the treadle-shaft, F the fly-wheel, s the fly-wheel shaft, 0 the crank, and T the treadle, all of which may be of any usual or preferred constructi on.
The described arrange- I with the treadle or with an arm secured to and projecting from the treadle-shaft, I connect the rod R with the treadle T through the medium of an intermediate lever, L, and in such manner that when the rod It and crank O are at their dead-points their axes will lie in a horizontal plane. In other words, instead of employing a vertical connecting-rod, I employ a horizontal connecting-rod, as shown. It is evident that with such a construction of treadlemotion, when power ceases to be applied to rod R will automatically carry the crank G beyond its dead-points, and in this position the parts will come to rest. The machine may therefore be started at any time by applying power to the treadle without first imparting motion by hand to a rotating element thereof-as, for instance, the flywheel F of a seWing-machineto overcomethe dead-points.
the operatingmechanism is properly balanced and the machine in proper running order to reduce the power required to convert the oscillating motion of the treadle into rotary moparts of the machine, I operate the lever indirectly from the treadle or the treadle-shaftthat is to say, instead of connecting the lever L directly with the treadle or its shaft, I emwith the treadle or treadleshaft to transmit the oscillations of the latter to said leverL. This may be effected positively or by friction in various ways. For instance, as shown in Fig. 1, the arm Z of lever L is connected with the rod R, and the arm Z terminates in a toothed segment, L, that meshes with a like segment, D, on lever D, whereby the vibra tions of the latter are transmitted to the former without great fatigue on the part of the operator. The vibrations of the lever D may also be transmitted to lever L by frictional contact between the two segments, their faces being slightly roughened or covered with some such substance as leather or rubber, whereby the necessary frictional contact is obtained.
the segments L D, as described, draft-bands or straps may be employed, as shown in Figs. 2 and 3. In this case I preferably employ three bands or straps, B B B, one end of the the treadle T, the weight of the connecting It being understood that the lever system of tion, and transmit the same to the rotatingv ploy an intermediate lever, D, connected either Instead of lining the contacting surfaces of straps B B being attached to one extremity of the segment 1), as shown at d d, and the other end to opposite extremity of segment L, as shown ati! Z, the intermediate strap, 13 having its ends secured to the opposite extremities, d I, respectively, of the segments D L, as shown in Fig. 3, in which, for the sake ot'elearncss, the segments are shown in dotted lines, and the straps in full lines. It is obvious that when the lever is vibrated by the vibration of the treadle T or its shaft S in the direction of the arrow, Fig. 3, for instance, the ends Z Z of the straps B B will pull on the segment L, causing the same to move in a reverse direction, while the endd" of the strap B will pull on segment I), assisting its motion in the direction of said arrow, whereby an easy reciprocating motion is communicated to the lever L, requiring comparatively little power.
Fig. i shows a further modification in the appliances for transmitting the trcadle-motion to the rock lever L, which latter, in this case, has the end ofits arm I forked, the lev r D can rying a pin, or a pin upon which is mounted a roller, 0', that reciprocatcs in the fork ofthe levcr L to rock the latter.
lnstead of the pin or pin and roller, a slidebloek of proper construction may be employed, and either the pin or roller, or the slideblock may be connected to the lever L, and the end of lever D may be slotted or forked. The arrangement of rook-lever L also provides a means whereby the throw of the treadle or the extent of the oscillations of the treadle-shat't may be varied without changing the length of the crank by simply changing the position of the fulcrum of the rock-lever; or, in other words, by changing the relative length of the leverarmsl and Z, as will be readily understood; and, further, in reversing the motion of the nu chanism, the inertia of the lever L tends to counteract or avoid the usual shocks and back throw due to the reversal of the motion of the treadle, whereby the devices operated will run much smoother than is the case when the motion of the treadle is communicated directly to the crank by means of a connecting rod.
Having thus described my invention, what I claim, and desire to secure by Letters latent of the United States, is-
1. In a trcadle-motion for sewing-machines, the combination, with the driven crank, a treadleslnift, and a treadle carried by and oscillating on or with said shaft, of a connectingrod, R, and intermediate mechanism to transmit the oscillations of the treadle or its shaft to the crank through the medium of the connecting-rod, as described.
2. In a treadle-motion for sewing-machines, the combination, with the driven crank and a treadle carried by and oscillating on or with said shaft, of a connecting-rod, It, a two-armed rock-lever, and intermediate appliances to transmit the vibrations of the treadle to the lever, and through the latter to the connect ing-rod and crank, as described.
3. In a treadle-motion for sewing-machines, the combination of the driven crank, a connecting-rod, and an intermediate two-armed lever connected to said rod, with a treadleshaft, a treadle, and a lever carried by and vibrating on or with said shaft, through which lever the vibrations of the treadle or its shaft are transmitted to the rock-lever and connecting-rod to rotate the crank, as described.
4. The combination, with the crank 0, connecting-rod R, and lover L. of the lever D and treadle T, and means, substantially such as shown and described, to transmit the move ments of the lever D to the lever L, as de scribed, for the purposes specified.
5. The combination, with the crank 0, connecting-rod It, and lover L, terminating in a segment, the face of which is provided with teeth or their specilied equivalent, of the lever D, terminating in a segment, the face of which is also provided with teeth or their specified equivalent, and the treadle T, all arranged for operation substantially as and for the purposes specified.
In testimony whereofI allix my signature in presence of two witnesses.
JOHX KAYSER.
