CONTROLLING DEVICE FOR MECHANICAL MOVEMENTS.

troller for. switches whereby the movements of the switch blade or bar will be limited to the functional area and directed with certainty therein; to provide a controlling' means whereby. the: switclubladeL- or bar can be operated by successive movements in the same general direction and be caused to assume a new functional :position for each sue cessive movement; to provide a switch-controlling device *by means of which the switch-blade or bar can be caused to assume different functional positions by successive pulls thereon in the same general direction; to provide a switch-mechanism comprised of certain simple units which are capable of indefinite increase for multiple structures and are susceptible of control, irrespective of number, by a single operating device; and to provide a controlling mechanism by means of which the several functional positions of a switch can be produced in succession without any change in the direction of application of power.

With theiabove objects in view, and others which Will-be detailed during the course of this description, my. invention consists in the parts, elements .and combinations of 'elements and devices hereinafter described andclaimed.

In the drawings forming part of this description: Figure 1 is a plan View of a simple device which ,I have chosen'to illustrate the principle of my invention; and Fig. 2 is a section on the line .2-2, Fig. 1.

Primarily, it should be understood that the structure shown in the drawings is but one form whichl have chosen to illustrate thegeneral principle of my invention and is not to be construed as a limitation, and in the description Wherever reference is made Specification of Letters Patent.

Application filed April 28, 1905. Serial, No. 257,882.-

Patented June 21,1910.

to a specific application of the invention to any given system or art, it is to 'be understood as explanatory of the general princi nles and not as a limitation.

Referring to the drawings, the nun'lcral 1 indicates a resilient, reciprocatory, switch bar or blade, in this instance of my invention. pivoted or hinged at 0!, upon a base of suitable material so as to swing or oscillate inthe arc of a circle under control in every movement. The base may be of electrical insulating material, and the bar 1 may or may not carry current according to its use. A reciprocatory bar 0 is likewise. pivoted or hinged at 7' adjacent the bar 1 and connected tothe latter by the link 5), pivoted to each ofsaid-bars so that the latter may move together, said link being of insulating material, if in an electrical system, to prevent short-circuiting. The bars are swung upon their pivots, in one direction, by means of the single pull-string '2, or other equiva lent device. guided and directed, if desired, by the guide-eye 0, fixed to the base or other adjacent support, said string being suitably connected at m,'to said link 9. lleturn movement is given to said bars, when released, by the spring 3, connected at one end to said link 9 and at its'other to said base or adjacent support. The movement of said bars is lilnited'in one direction by means of the stop-pin 8, projecting from the base, and in the opposite direction by the stop-pin 8, also projecting from the base. These two stops prescribe the extremes of movement of the two switch-bars and constitute the boundary of the functional area of operation of said bars. "ithin this functional area is located a combined guide and catch 4, and. if in an electric systen'i, said catch will also be a current contact or tern'iinal. and an additional terminal contact '7 may be located in this functional area for two pole-switch circuits.

'cam, or guiding device. and its lower guide arm or prong 4 is bent so as to depress its end substantially into engagement with the base so as to form another cam or guiding open end, is the shunt-guide,

' with the arm 4*.

I suitable manner, it being understood that,

Cooperating with said catch 4, at its having its guiding device or arm 5 bent so as to be elevated from the base, to be sli htly convexed so as to be substantially in contact with the end of arm 45 .of the catch, and to have its outer end substantially in contact The guide or arm 5 is secured by its shank 5 to the base in any suitable manner, and the'catch-contact or catch 4 and terminal'7 are secured to the base in any in an electric system, the catch-contact 4:, device 7 and switch-bars are current terminals, as presently described.

Each of the bars 1 and 6 is made resilient,-

minal contact 7 and shunt-guide 5, may be catch-contact is made sunning it is desired to switch in the current, the cord, or equivalent device will be pulled to the left, Viewing Fig. 1, which will cause allow saidarm to pass and assume the position indicated by 1, Figs. 1 and 2, this being the extreme of movement to the left which brings said bar '1 into engagement with the s'top8 The cord now being released, the s ring 3 will assume control and retract said ar 1, so as to draw itinto the dotted-line position indicated at 1', said bar be seen that-the location of shunt-guide 5 is such-that switch-barl' cannot slide under said shunt-guide, but must-ride over the top thereof and under the'arm 1 of the catch. Another ull in the same direction,to the, left,w' draw the'switch-bar 1 into the dotted-line'position indicated at 1, the move-g ment of said'bar bein or to the limit of the left, whereupom-when the said 'stringfis'ree" le'ased, the's ringwill again controLand the resiliencyJo thefbar 1 will enable it-to flex" and ride over the top of the guide arm 14*" ofthe catch, and engage the stop 8,which isagain to the stop '8? 1 operation of the: switchbar, said stop8 holding-said. bar in the full-lifted position indition. Another the art to understand mechanism to control or duplicate its functions, without changing cated in Fig. 1. Assuming, now, a doubicpole switch system, another unit may be coupled with the one just described, without changin the mode of operation or control ofthe rst unit in any respect; that is to say, within the same functional area the bar 6 and contact 7 are located, the bar 6 being coupled to bar l by the insulated link 9. A pull to the left on the cord carries the bar 6 over to position l in unison with bar 1 to position 1 and release of said cord allows the spring to carry bar 6 into engagement with terminal 7, in unison with movement of bar 1 into the loop of the catch, the latterthus also holding bar 6 in operative posipull to the left' on the cord causes the bar 6 to move to position 1 again in unison with movement of bar 1 to position 1, the release of the cord causing spring 3 to drawthe bar'6 against stop 8, the bar 6 thus being the means for holding bar 1 in an inoperative position. This simple illustration of the form disclosingthe principle of my invention will enable anyoneskilled in how the units of'the mechanism may be multiplied at liberty;. that is to say, with a single-pole switch in the circuit the switch-bar 1,,catch-contact 4 and shunt-guide 5, with stops 8 and 8 on opposite sides, would constitute the unit of my switch, while in a double-pole circuit, to such unit would be added the switch-bar 6,

contact 7 and link 9 connecting,the'two bars 1 and 6. In either a sing-lerpole switch cir-.

cuit consisting of the elements forming the unit just described, or in a double pole switch circuit containing the elements just. described as forming the double unit, the recombined, or the elements thereof can be multiplied to any extent found necessary for any given number or character of circuits without changing either the construction, mode of operation, or the uni-directional character of the pull to operate the same within the functional area prescribed by the stops 8 and 8*.

From the above description and mode of spective units, singly or operation, it will be seen that the following,

in addition to .those already incidentally noted, are among the advantages of my invention: A switch-mechanism is provided which is controlled by a device adapted -to be pulled in a single direction, and for each I pull in the same direction, a difand every ferent result or function is secured; a switchmechanism is produced having a few simple elements which may be increased indefinitely, one or more of them, in order to adapt sald aplurality of clrcuits,

its mode of operation or structure in any material or essential particular "a switch-mechanism is produced which can be appliedso as to control a plurality of direct "circuits either simultaneously or in succession; a conteract-ion, functional result, or mechanical.
