Iil() Patented sepelz, 1933 UNITED 1,926,419 CONTROLLER vincent c. Appla- Dayton, ohio, assignor to Bendix Brake Company, South Bend, Ind., a
corporation of Illinois Application January 16, 1930. t Serial No. 421,328 5 Claims. (Cl. 201-51) My invention relates to a controller element for an electric circuit and has particular reference to a device whereby varying resistances may be inserted in the circuit of an electric brake hook-up.
An object of my invention is to provide a controller which will permit the utilization of a large resistance range, and-be capable of handling comparatively large amperages. The use of various types of electric brakes is quite prevalent, and I particularly contemplate a controller 'element which may be governed entirely by thepressure exerted by an automotive vehicle operator uponthe conventional brake pedal.
Various means of changing the amount of resistance in any circuit have been utilized hitherto, but in `my controller, device I have incorporateda plurality of independent resistance elements and in addition to varying the resistance in each of these I have devised means for varying the manner in which they are placed in circuit and thereby varying the total resistance.
Various other objects and meritorious features 'of my invention will be apparent from the following description taken in conjunction with the` tric connections.
I have illustrated my controller -as embodying a casing 10 which is, provided with two tubular compartments 12 and 14, each of which is insulated from the casing by a lining 16.. `Each of these tubular compartments is divided into sections W, X,'Y and Z by a terminal plate 18 which is provided with terminal facilities 17 and 19, and each of the sections contains a pile of carbon discs. While I have disclosed the use of carbon disc piles as constituting my resistance elements, it is to be underst od that other resistance elements may be ut" d with equal success. Y Through the center of my casing member 10 thereis an axial bore 20Y through which the cam rod 22 is designed to slide. Slidable along the end of this cam rod is a plate 24; This plate is insulated from the rod by means of the plates 26 and thebushing member 28 supports the plugs 30 which bear on the carbon piles in the tubular compartments. These plugs 30 are secured to the plate assembly. as specified by means of the nuts 32 and 32 and function to compress the piles of carbon discs as tension in ca'rn rod 22 is 60 increased. Nut 32 also provides a terminal facility.
A second plate'34, insulated by means of plates 36 and secured to cam rod 22 by means of the nut 38 provides a seat for the spring member 40, 65 the other end of which bears against the plate assembly comprised of plates 26 and 24. This plate 34 also carries the terminals 42.
At the opposite end of my controller member are seated the conducting plates 44 which are 70 insulated `from thehousing 10 by means of the washers 46. These plates contact the bolts 48 and 48 which, in turn, are insulated from the housing 10 by washers 50, and support the terminals 52 and 52.
It is to be noted that the terminal plate 18, which functions to partition each of the tubular compartments to provide four independent resistance units is vso arranged in slots 54 in the outer periphery of the casing member 10 as to be slidable to some extent with relation thereto. Y
Secured to the base of my controller element is an insulation plate 56 which is held in place by means of the screws 58. Aplurality of contacts 60A to 60G, each of which is threaded through the insulation plate 56 and carries at its outer extremity means 62 for securing a terminal, extend throughout the length of the controller unit and are located in alignment ,with the axial bore 20.
One wall -64 of the axial bore 20 is provided with a plurality of apertures 66 which are in alignment with the contact members above speciied. A series of studs 'wwhich carry the contact bridge plates .68A to 68F is inserted in each of these bores and normally held in the position illustrated in Fig. 1 by means of the spring '72 which surrounds the stem of the stud '10 and is seated against the inner side of the casing wall.
A contact bridge plate, arranged as'just described, is located between each of the contacts and normally retained in a position `to maintain anV open circuit through the contact members' 60.
Seated inv the apertures 66 and upon the stud members 70 is a ball '73.- This ball bears against the external periphery of the camming rod 22 and transmits the camming action of the said rod as it moves axially in its bore to the stud 70 and thus bridges the contacts 60.' u
The end of the camming rod opposite the plates 11 24 and 36 is provided with means which may be linked up with some mechanical linkage connected with the customary brake operating pedal.
The operation of my controller unit when utilized in conjunction'with a brake pedal will be apparent from the above description and a brief 4study of the circuit diagrams disclosed in Figs. 5, 6, and 7. In Figs. 4 I have illustrated, somewhat diagrammatically, the controller unit hooked up with a conventional storage battery 74 and an electric motor 76 which latter may be of the type used to provide power for vehicle brakes.
As illustrated, there are four stages of operation of my controller device, thus providing four different resistances. which are ordinarily incorporated in the electric circuit during the application of the brakes. The first stage vis iillustrated by the diagram shown in Fig. 5 wherein each of the carbon pile resistance units is connected up in series withlthe motor. It will be apparent from inspection of Fig. 5 that the current from battery 74 enters the controller through terminal 48 and ows through the carbon piles Y, Z, X, and W consecutively, thence to contact 60-B and lacross the bridge plate 68-,A to contact 60-A, and ilnally back through `terminal` plate 34 and through motor 76 to ground. Upon further move- `Fig. 6 with little diiiiculty. From the battery 74 the current flows tothe terminal 48, at which point it splits. One of the divisions flows through carbon piles Y and Z to terminal 32', thence to contact 68D, across switch blade 68D to contact 60E, and thence out through terminal plate 34 and through the battery. The other division in the circuit carries the current from terminal 48 to contact 60C, across switch plate 68B to contact 60B and thence through carbon piles W and X to joinvthe other division in the circuit at terminal 32', fromv which point it iiows to the motor as already indicated with respect to' the rst division in the circuit.
Upon further movement of the cam rod in the direction of the arrow a circuit such as the one illustrated in Fig. 7 will result. Under these conditions each of the four resistance units is connected up in parallel and the a secondary split. One of these directs the current across plate 68B to contact 60B, thence through carbon pile W to terminal 17, on to contact 60G, across plate 68F to contact 60F where "it again finds the main line to cross plate 68E and thence to the terminal plate 34 and on to the motor. The other portion of the secondary e split which occurs at contact 60C directs the current across plate 68C to contact 60D, thence to terminal 32 at which point the circuit divides to go through the carbon piles X and Z respectivelyto terminals 17 and 19, from which point they are directed back to the contact 60F,
across plate 60E etc., on to terminal plate 34, the motor, and ground.
Upon 'still further movement of thecam rod the contact members 78 will bear upon the contact members 32 and thus all of the carbon pile resistance will be short-circuited, or shunted out of circuit, and the entire flow of current or maximum amperage which may be derived from any given voltage will be permitted to flow to the electric motor 76.
It will thus be seen that I have provided four distinct power values which may be utilized to apply the brakes through an electric motor, or any electro-magnet device, and it is obvious that any number of predetermined resistances may be inserted inthe circuit by the means illustrated. Asillustrated, it will likewise be noted that` during the period in which the respective carbon piles are brought into circuit in various relations of series and parallel each of the carbon piles is being compressed to decrease the resistance in each respectiveA pile. By' virtueof this two phase variation, one of which involves consecutive shifts from one circuit to the other and the other of which involves a constant decrease of resistance in each individual unit, a very wide range of electric power transmission is secured. It will be clearly seen that as the tension rod 22 is pulled axially through the controller the spring 40 will be urged against the insulation plate 26 to gradually increase the pressure exerted through plungers 30 upon the carbon piles. Furthermore, the insertion of theseresistances is in direct ratio to the pressure exerted upon the foot pedal of the vehicle by reason of the cam rod being directly actuated by some mechanical connection with the brake pedal itself against increasing tension in spring 40. `By making spring 40 as powerful or as light as desired, a corresponding powerful or lightl eiort exerted on the brake pedal will produce the same ratio of applied force to the brakes. f It will be readily understood that the -camming action produced by the axial sliding movement of rod 22, and consequent making and breaking of the various switches, may be utilized to establish anyA desired circuits, reverse circuits, etc., as well as to vary the manner in which resistance units are included in the circuit.
Having illustrated a preferred embodiment oimy invention various other modifications will become apparent to those skilled in the art and for that reason I intend to limit myself only within the scope of the appended claims.
