APPARATUS FOR TRANSMITTING POWER.
SPECIFICATION forming part of Letters Patent No.
298,672, dated May 13', 1884.
Application filed July 30, 1883. (N0 model.)
To aZZ whom it may concern.-
Be it known that I, Pnosrnn AOHILLE Do- I-IIs, of Paris, in the Republic of France, have invented certain Improvements in the Means or Apparatus for Transmitting Motion (Driving) to Machinery; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification-that is to say:
This invention relates to certain improvements in the means or apparatus for transmitting motion to machinery, the object being to supersede and remedy the defects of the devices for operating machinery by hand or foot hitherto employed. This is effected by placing between the machine and the source of power a barrel or cylinder containing an accumulator-spring, so as to store the force. This improved system will be of great service in the working of saws, lathes, mills, sewingmachines, and, in general, all machines, tools, or apparatus which have been operated by manual labor, at the same time that it gives a positive movement.
I will, by way of example, illustrate this invention as applied to a sewing-machine, and as shown in Fig. 1, which is a perspective view, and Figs. 2, 3, and 4c represent sectional views. The operative is shown seated at the table with the feet'placed on the two treadles A 13, whereby the action is brought upon the spring R by a simple direct action of the treadles, which operate the segment frictionclutch pieces or talons T T, which act in grooves of the wheels r1, alternately. WVhen once the spring is coiled up in the cylinder, said cylinder acts simply as an accumulator in which the reserve of force will be keptup by the action of the treadles, operated either together or one after the other, or by one alone. The
operation of working these treadles presents the advantage over the ordinary ones of a more powerful and longer thrust, and may be effected without the ordinary necessary and tiresome regularity, and with less rapidity, thus caus-,
ing less fatigue to the operator. The extension of the spring produces the revolution of the driving-wheel E of the spring-barrel, and gives motion through the multiplying train of wheels P P and pinions p p, of variable number, according to the requirements, to the last wheel D, the axis of which carries the grooved wheel V, which vby a belt transmits the movement to the pulley o of the sewing-machine.
It should be observed that the winding up of the spring by the feet, whereby the hands are left completely free on the table H, constitutes a remarkable novelty, which is an integral part of my invention, together with the operation of the talon T, which actuates by friction the groovedwheel r for effecting the rolling up of the spring R, as shown by the direction of the arrow f, without catch or ratchet, in order to do away with the very disagreeabe and intermittent noise so common to these machines. Similarly, another frictionclutch or talon, T, actuates the grooved wheel 1", which acts as a stopipiece to stop the direct unwinding of the spring, as shown by the direction of the arrow f. By this arrangement the operative will be able to obtain without fatigue a speed which it is absolutely impossible to obtain with the pedals, and whatever may be the rapidity of the movement of the needle the legs of the operative do not move faster. The speed of the machine is, however, regulated by means of a flexible plate or brake, F, fixed under the table at I, and which is worked by the right knee of the operator, and acts by friction on the wheel V and slackens it. The complete stoppage of the machine is obtained by means of a handle, m, Fig. l, which acts immediately to stop the pulley o.
All the transmission parts are inclosed in a cylindrical box, M, fixed under the table H by the screw N.
The employment of an accumulator-spring inclosed in a cylinder and a fly-wheel regulator of the power in machines or apparatus which have hitherto been actuated by living motors is of great mechanical advantage, because this spring, being placed between the power and the resistance, has for effect to produce regular application of the power in contradistinction to the irregularity of action inherent in living motors.
Having now described the nature and particulars of my said invention, I claim-- The improvement in the means or appara tus for transmitting motion to machinery, the treadles A B, spring R, segment friction-clutch T T, acting alternately on wheels R R to wind the spring R, which spring acts to revolve the 5 driving-wheel E, acting to give motion,through the train of wheels P P and pinions p p, to the wheel D, upon which the transmission-wheel V is carried, with or Without brake F, and handle m, constructed and operating as and for the purpose herein set forth, and shown in the I drawings as applied to a sewing-machine.
In testimony whereof I, the said PROSPER ACHILLE DoHIs, have hereunto set my hand this 18th day of January, A. D. 1883.
PROSPER AGHILLE DOHIS.
