Definitions

  • the switch blades are molded into wafers which can be stacked to provide an assembly having grouped terminals for a suitable connector cable. Selected blades can be interconnected by a variety of bussing methods.
  • the active blade end engages a guided follower which rides on the cam and is not sensitive to direction of rotation of the cam.
  • the passive blades abut stops in the follower guide to eliminate need for adjustment.
  • Axial movement of the cam arbor actuates a line switch in one of the switch assemblies.
  • a drive cam can actuate another switch which can also be actuated by the main cam.
  • the cam arbor is mounted between end plates spaced by the motor mounting plate and the motor bearing is free of radial loading.
  • This invention relates to timers of the type used in programming washing machines and the like.
  • the accepted form of such a timer utilizes a rotary cam which actuates switches, each having the active blade formed to ride on the cam.
  • the switches generally required adjusting after completion of the assembly of the timer and this adjusting could affect the actual point of contact with the cam and, hence, slightly change the timing sequence. This becomes of some importance when it is realized that when the cam is stepped it is often desired to axially sequence operation of the switches within the time it takes to step the cam one step.
  • the prior art arrangement also resulted in terminals being arranged over a large area and usually on more than one side of the timer making simple wiring connections virtually impossible and, hence, the time required for installation in the washing machine was longer than desirable. Separate hand wiring was required for interconnecting various blades. The designs have been limited to having the manual knob shaft extend in only one direction and frequently loaded the motor bearings.
  • This invention is directed to the simplification of manufacture, assembly, and installation of timers while at the same time reducing the size and increasing the reliability of the product. This has been accomplished in various ways.
  • the cam arbor is journaled between end plates in such a way that the arbor provides its own bearing while being isolated from lateral loading which could result in misalignment.
  • the drive is mounted to eliminate loading of the motor bearings.
  • Each switch assembly includes three wafers and each wafer includes the blades assigned to that wafer molded into a plastic block.
  • the portion of the blades within the block is provided with a configuration providing, where desired, suitable tabs which align with cooperating holes in the wafers.
  • the switch assembly is designed to have the active blade in the middle wafer and the end of this blade projects into a guided follower which rides on the periphery of the selected cam.
  • the follower itself is guided for movement normal with respect to the cam and, hence, is precisely positioned and is not limited to a single direction of cam movement with respect to it so all terminals can now face one direction even though assemblies are positioned on opposite sides of the cam.
  • the passive blades in each switch assembly rest on stops on the follower guide and these stops serve to accurately position the passive blade ends. With this assembly there is no need whatsoever for adjustment and yet a higher degree of accuracy is obtained.
  • the invention is shown in connection with a drum-type cam but is readily adapted to a disc-type cam.
  • FIG. 1 is a partial exploded perspective view giving the general orientation of the parts
  • FIG. 2 is a simplified showing of the drive mechanism together with the subinterval switch arrangement
  • FIG. 3 is similar to FIG. 2 but shows the subinterval switch mechanism in its inactive position and the switch under control of the main cam;
  • FIG. 4 is a simplified exploded View of a switch assembly
  • FIG. 5 is an enlarged detail view of a typical bussing arrangement for the single throw blade wafer, that is the upper wafer of the assembly;
  • FIG. 6 shows the active or middle wafer typical arrangement
  • FIG. 7 is the lower or double throw wafer typical bussing arrangement
  • FIG. 8 is a representative plan view of an assembly showing various bussing arrangements
  • FIG. 9 is a section taken on the meandering section line 99 of FIG. 8 to show the various bussing arrangements
  • FIG. 10 is a perspective view of the inter-row bussing clip
  • FIG. 11 shows the way in which a terminal can be connected to one of the wafers
  • FIG. 12 shows the intra-wafer bussing
  • FIG. 13 is a fragmentary enlarged perspective View of the follower guide block
  • FIG. 14 is a simple showing of the manner in which the follower is guided in the guide block which supports the ends of the passive blades;
  • FIG. 15 is comparable to FIG. 14 but shows the active blade in the middle position not contacting either the double or single throw blade;
  • FIG. 16 shows the single throw action
  • FIG. 17 shows the manner in which the axial motion of the timer shaft is transferred to the line switch
  • the main timing cam is mounted between front plate 12 and rear plate 14.
  • the cam 10 is an integral molding with a central shaft 16 having a reduced end which is piloted in bushing 18 mounted in the front plate.
  • the other end of the cam has a projecting shaft portlon WllJCh projects through the cooperating hole in the rear plate with the end of the cam shaft being suitably slotted to receive the webs 20 of the line switch operating disc 22 carried by plastic hub 24 which has two peripheral grooves in either of which the detent spring 26 may rest.
  • the plastic hub 24 is rigidly fixed on shaft 28 which projects through the cam and out the front plate 12 for mounting of a suitable actuating knob. Shaft 28 could project from the other end, which may be des red in some cases.
  • the circular portion of the detent spring 26 seats against the inside face of the rear plate 14 and the shaft can be moved from the position shown in FIG. 17 to a more rearward position in which the spring 26 seats in the other peripheral groove on the hub 24.
  • the shaft is, drivingly connected to the cam through the webs 20.
  • This moves the operat ng disc 22 rearwardly and as a result the slider 38 having cam face 32 engaging the disc 22 can move inwardly under influence of the inherent spring force in the active blade 34 acting through its follower 148.
  • the active blade has been moved into contact with the cooperating single throw blade 36.
  • the circuit through blades 34, 36 is broken and when the knob is pulled out, the circuit is made.
  • This switching function accommodates the so-called line switch function and at this point the detail mounting of the blades per se will be put off.
  • Both lpawls are biased into engagament with the ratchet teeth on the cam drum periphery be means of spring 58
  • Indexing cam 46 and its associated gear 48 are mounted between plate 12 and the facing surface of motor mounting bracket 60 which has a plate portion 62 which acts to space the front and rear plates 12, 14.
  • the cam and gear member also includes a peripheral skirt-like cam portion 64 having various cut-out portions into which follower 66 of link 68 pivoted at 70 may drop.
  • the other end of the link carries an insulated portion 72 which underlies a laterally projecting finger on guided follower 146 to act on the finger to lift the follower and, hence, the active blade 76 when follower 66 rides on skirt 64.
  • the follower 146 can also be actuated by the cam 80 of the main cam on which it rides. This can happen only when the follower 66 can drop into a cut-out in the skirt 64.
  • the interconnecting web W may be left in place or may be sheared out by punching through the aligned hole after the molding is completed as shown in FIG. 12 where the webbing has been punched out at hole 102 but the webbing has been left intact at the next adjacent hole 104. This, then, is a simple method of interconnecting the two blades. This is one of the versatile features of this design.
  • the blades above the active blades A are the single throw blades B in FIG. 4. These blades have a typical root or proximal portion as shown in FIG. 5.
  • the double throw blade assembly C has a typical root configuration as shown in FIG. 7. It will be understood that in each wafer there is a web portion W which may or may not be trimmed out after the molding of the wafer is completed.
  • FIGS. 5, 6 and 7 are shown in general parallel alignment to better visualize the manner in which the wafers are stacked. It will be noted that in the portion of the blades molded into the wafer there are three distinct zones in each instance. These zones, for convenience, will be referred to as X, Y, and Z.
  • zone X On the single throw blades (which will be the uper wafer) in zone X there are punched out holes 106 into which the tabs 108 project.
  • zone X On the single throw blades (which will be the uper wafer) in zone X there are punched out holes 106 into which the tabs 108 project.
  • zone X On the single throw blades (which will be the uper wafer) in zone X there are punched out holes 106 into which the tabs 108 project.
  • zone X on the double throw blade while on the active blade the space which will align with the holes in the single and double throw blades and which is designated 110 on FIG. 6 is merely a void. Therefore, when these blades are stacked and the cooperating holes are molded into the wafers the single throw and double throw blades can be interconnected by driving a buss member through the cooperating holes to engage the tabs 108 in the top and bottom wafers of the assembly.
  • each active blade is provided with a hole 112 into which the tab 114 projects while the double throw blade is provided with a cooperating hole 116 into which the tab 118 projects.
  • the single throw blade in this zone Y has a void 120 which will align with the holes 112, 116 in the other blades. This, therefore, makes possible interconnecting the active and double throw blades by driving a buss through the aligned holes.
  • each blade is provided with an aperture 122 and tab 124 permitting bussing through all of these in the Z zone.
  • FIG. 8 This concept can be carried forward in an assembly shown in plan view in FIG. 8 and in cross section in FIG. 9. This gives some idea of the versatility of the present design by way of freedom of interconnection of various blades.
  • the section line on FIG. 8 is a meandering line which passes through the different zones. Going from the terminal end of the blades, the first row of horizontal holes affords access to the webbing W interconnecting the various blades and it is through these holes that the webbing is trimmed when it is desired to separate adjacent blades as would be most normal. The next row back is the Z zone followed by the Y zone and then the X zone.
  • FIG. 9 refer first to the buss 126 which is driven through the vertically aligned holes in the X zone.
  • this buss 126 can only engage the single throw blade and the double throw blade but cannot connect to the active blade.
  • the top blade is connected to the bottom blade very simply.
  • buss 128 This buss has been pressed into the assembly in the Z zone and if pressed far enough would obviously engage all three blades but this would rule out any possible utility so the buss is made short enough to reach only into the middle wafer and thus connect the top or single throw blade with the active blade.
  • buss 130 which appears best in FIG. 10.
  • This buss member in plan view is in the nature of a U-shaped clipbut has depending legs 132, 134.
  • leg 132 is pressed into the Y zone and, in accordance with the principles above, we know that there is a void in the Y zone in the upper single throw wafer. Therefore, no connection is made here.
  • the leg is made only long enough to pass through the second or middle wafer where it can make connection to the active blade.
  • the other leg 134 projects into the Z zone where all the blades have aligned holes with cooperating tabs but since the leg 134 is only long enough to project into the upper wafer it connects only to the upper blade.
  • the U- shaped buss 130 we have now connected the upper blade (with leg 134) in one row to the active blade in another row (through leg 132).
  • buss members are slightly thicker than the normal clearance between the hole and the tab projecting into the hole in the blade. Therefore, the tab is bent down as the buss enters the hole and acts as a locking device preventing withdrawal while insuring good electrical connection.
  • FIG. 11 shows a male terminal 136 having in this fragmentary view a buss portion 138 passing through the upper wafer and engaging in the active wafer with the ramp 140 formed on the end of the buss locking under the tab to prevent withdrawal of the terminal.
  • a female terminal is mounted on the male and later disconnected it will not pull the terminal from the assembly.
  • the active blade has a narrow projecting tip which is designated 142. Also note that the active blade is longer than the single or double throw blades. This allows the tip portion of the blade to project into the aperture 144 in guided follower 146.
  • the protruding end 148 of the follower rides on the cam contour.
  • the edges of the follower 146 are received in and guided by vertical grooves 150 in the guide block 152 fixed between the end plates with the portion 154 projecting from the ends of the guide block mounted in suitable apertures in each of the end plates to positively position the guide block so that it is positively oriented with respect to the main cam and, hence, the followers 158 are positively oriented with respect to the cams upon which they will ride.
  • All the active blades are formed to be self-biased downwardly so that the followers 148 are biased by the active blades to ride on the cam.
  • Each single throw blade 156 projects toward the guide block to overlie and rest the upwardly facing stops 158. Since the single throw blades are also initially bent downwardly they are self-biased firmly against these stops. The double throw blades are of sufficient length to underlie the lower stop surfaces 160, also formed on the guide block assembly. These blades are bent upwardly so that they also are self-biased to their stops.
  • the active blades pass between the positively located upper and lower (or single and double throw) blades to' engage and bias downwardly the vertically slidable followers which ride on the cam.
  • the normal or open position is shown in FIG. 15 where the active blade is positioned by the cam surface between the single and double throw blades and, therefore, no circuit is made.
  • the follower has moved (under the blade bias) onto the lower cam surface and the active blade has moved into contact with the double throw blade 164.
  • the double throw blade will be moved downwardly olf its stop surface 160. If the converse is true of the bias of the blades the active blade would stop movement upon contacting the lower blade. It will be appreciated that abundant self-bias can be employed in these blades and this will result in excellent contact pressures. There is also a distinct wiping action between the contacts which helps break any welds that may occur.
  • followers 148 are guided by the guide block to substantially radial action with respect to the main cam drum. For this reason the direction of approach of the cam relative to the follower has no effect and now the upper and lower blade assemblies can be positioned to position all terminals at one side of the timer. This means wiring clearance need be provided in the appliance on only one side of the timer with a significant space saving.
  • main cam is rotatably mounted in the rather rugged stub shaft 18 there can be no transferal of radial loads from the drive mechanism to the main cam or to the motor bearing.
  • a timer including a rotary timing cam
  • each switch including an active blade and a passive blade
  • each active blade slidably engaging a follower to be actuated thereby with the blades being biased in a direction forcing the followers into contact with the cam, stop surfaces on the guide block,
  • each passive blade engagmg a stop surface and being biased thereagainst.

  • a switch mounted adjacent the cam and including a passive blade and an active blade having a follower engageable with the timing cam for actuatlon thereb K162131718 actuated by the rotating element and engageable with said follower to actuate the switch independently of the cam.
  • a timer including a rotary timing cam, an assembly of parallel switches mounted adjacent the cam with each switch including an active blade and a passive blade,
