These cranks are each associated with a link B' C' D', said links being mounted at their upper end upon the shaft E.

CONTROLLING DEVICE FOR MOTORS.
SPECIFICATION forming part of Letters Patent No. 674,643, dated May 21, 1901.
Application iiled December 28, 1896. Serial No. 617,161. (No model.)
To all whom it may concern,.-
Be it known that 1 1, HARVEY S. BRISTOL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Controlling Devices for Motors, of which the following is a specification.
My invention relates to controlling devices for motors, and has for its object to provide a new and improved controlling device, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure l is a plan view of a controlling device embodying my invention. Fig. 2 is a section on line 2 2, Fig. l. Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4is a section on line 4 4, Fig. 2, with parts omitted.V Fig. 5 is a detail view of the power-transmitting shaft.
Like letters refer to like parts throughout the several figures.
My controlling device may be used in connection with any kind of a motor and in connection with any mechanism which such motor may be used to operate.
The power-transmitting shaft A is operatively connected With the motor in any desired manner and is provided with cranks B, C, and D. I have shown this shaft with three cranks; but l may use any number of cranks desired. When the three cranks are used, I prefer to place these cranks one hundred and twenty degrees apart. These cranks are each associated with a link B' C' D', said links being mounted at their upper end upon the shaft E. These links are provided with the slots A', and the crank-pins A2 pass through said slots. Said links are also provided with the slots A2, in which work the sliding blocks A4, to which are pivotally connected the arms B2. A series of downwardlyprojecting arms B3 are also pivotally connected with said blocks, said latter arms being connected with the arms B4, which are preferably rigidly connected to the rock-shaft E'. A lever E2 is connected to said shaft and is provided with a rack E3 and a locking device E4, so that its position can be varied. The movement of this lever E2 varies the position of the sliding blocks A4. The rods B2 are pivotally connected in any desired manner to the gripping-plates F, associated with the wheels or disks F', rigidly connected to the shaft F2. 'Ihese gripping-plates F are preferably constructed as shown, and consist of a body portion having the gripping ends F2 F4, which engage the flanges or rims of the wheels F'. These anges or rims are preferably beveled at F5, as shown in Fig. 3, the gripping ends of the plate F being beveled in a similar manner. The lower end of the plate is provided with two projecting ends F6 F7, which project downwardly, one on each side of the shaft F2. The distance between these ends is greater than the diameter of the shaft, so that the plate can be moved relative to said shaft. A key F8 passes through each of said gripping-plates and engages the shaft F2, being preferably held in place by the screw F2. This key allows the mechanisni to be adjusted for wear. Connected to each one of the locking-plates is a rod G, which passes through a sleeve G', connected to a projecting arm on the shaft G2. I prefer to construct this arm as shown in Fig. 4 and provide it with the two branches G2, the sleeve G' being located between said branches and being held in place by the screws G4. Located on each side of the sleeve G' are the springs G5 G6, one end of each spring engaging the sleeve, the other end of said springs engaging suitable stops. The shaft G2is provided with the controlling-lever H, by which its position maybe varied, said controllinglever being provided with some suitable locking device by which it may be held in any desired position. I prefer to form the wheels F' as shown in Fig. 3, so that they have a projecting hub F10, so that they can be connected to the shaft F2 by means of a set-screw. I have shown only three wheels and accompanying parts; but it is of course evident that any greater number may be used, ifrdesired; but I do not think it necessary to show more than three. Instead of using the cranks B, C, and D, I may of course use the ordinary eccentrics; but I prefer to use the cranks, because they occupy less space. The several shafts are of course mounted in suitable bearings, and the device to be driven by the m0- tor is connected with the shaft F2. I have described these several parts in detail; but it is evident that they may be varied in form, construction, and varrangement without de- IOO parting from the spirit of my invention, and I therefore do not wish to be limited to the construction shown and described.
The use and operation of my invention are as follows: When it is desired to transmit power from a motor to a driven device, the motor is connected with the shaft A and the driven device with the shaft F2. When this is done, the driven device may be stopped and started and driven at any desired speed without in any manner controlling the motor, said motor running at full speed all the time. It is very desirable to produce this effect in many mechanisms-as, for example, in the use of gas-engines when used to drive horseless vehicles or when used for any other purpose, as such engines are not efficient at the start and are only able to do good work when run continuously. When it is desired to operate the driven device, the sliding blocks A are moved toward the lower end of their slots by means of the lever E2, shaft E', and arms B3 B4, dac. As the driven shaft A rotates the cranks rock the links B', Ol, and D', thereby reciprocating the arms or rods B2. The movements of these rods cause the grippingplates to move and one of the gripping ends F3 or F4 to engage the periphery or rim of said wheels and rotate same. If, for example, the parts are in the position shown in Fig. 2, the gripping end F3 will come in contact with the rim of the wheel as the arm B2 is moved outwardly and rotate said wheel in the direction of the arrow. As the cranks of the shaft A rotate the rod B2 will be moved backwardly and the gripping end F3 disengaged from the wheel, thereby allowing the gripping-plate to be moved back to its operative position. Since the cranks are situated one hundred and twenty degrees apart, the other grippingplate,or at least one of them, is being movedin an opposite direction, while the plate connected with the rod B2 is being moved toward its operative position, thereby producing a continuous movement of the shaft F2. It will be seen that the throw or distance of movement of the arms B2, dac., is controlled by the position of the sliding blocks A4, and hence the speed of the driven shaft or driven device is .easily controlled by moving these sliding blocks through the agency of the controlling-lever E2. If said blocks are moved to the upper ends of the slots A3, there will be no reciproeating movement of the arms B2, for example, and hence the driven shaft or driven device will remain stationary. The motion of the driven shaft can be reversed by moving the lever H. If said lever is moved in the direction of the arrow, (see Fig. 3,) the several gripping-plates through vthe agency of the rods Gr and associated parts will be moved so that the shaft F2 will be nearest the projecting arm F7. When in this position the gripping end F3 will be free, While the gripping end F4 will be in operative connection with the wheel, and hence the motion of said wheel will be reversed.
It will therefore be seen that I have here a controlling device for motors by which the driven device may be stopped or started or operated at any desired speed while the motor is running continuously and at a uniform speed, therefore controlling the driven mechanism independent of the motor.
