QCIamS..vr (Cl. 268-125) mobiles have been hydraulically actuated, it being merely-necessary to press aV button torender the mechanism operative. Although these mechanisms are to an extent satisfactory and accom- 'plish the purposeintended, nevertheless, they are somewhat delicate and unless manufactured, assembied and -installedwithv careycause trouble. Furthermore,` 4there is a distinct desideratum to producing a simple and efcient ymechanismv of this character which is -free-fromthe manufacturing, assembling and installing problems inherent in similar existingV devices and also one which is Arelatively inexpensive.

An object is to produce a regulator mechanism which operates-in-response to pressure fluid which is simple in construction, 4inexpensive t0 A manufacture on large scaleproduction, canbe produced largely from stampings and castings, and which has a minimumY of moving parts.

Another object is-to produce ahydrau'lioregulator for vehicle windows and thelike, in lwhich use is madein oppositedirectionsof the-effective hydraulic pressure.

A further objectv is kto produce aregulator-for vehicle WindoWs-orthelikeof the cross army-type inV which Vthe motor-is arranged substantially in the region of the arm intersection.

' A still further object is tol produce a newand improvedr hydraulic regulator' assembly which' vcan be mounted as annit in-the doorwell for example, and which-,embodies a hydraulic motor in which efficient use ismade of the-pressure lexerted in both directions.

and

equipped with vertically adjustable glass window Y panels l5, and disposed rearwardly of the doors I4 are so-called rear quarter glass window panelsy I6 which are also mounted vfor up and down movement. In each instance, the vertically adjustable windows have the usual laterally spaced guide channels or strips in which the vertical` side edges of the panels slidably engage, such, for example, as indicated by the reference numerals l1 and I8.

As will hereinafter more fully appear, each of thewindow panels l2, I and IB may be hydraulically actuated in one direction or the other bythe simple manipulation of a control instrument such as a lever L conveniently arranged on Vthe inside of the body. The construction and arrangement is such that one Window of the system may be moved, for example, downwardly, "and simultaneously another Window moved upwardly or in the opposite direction, While other Windows may remain stationary or in the position of adjustment. Hydraulic pressure for effecting such Window movement is supplied by a motor and pump unit P which, as shown, includes Aan electric motor E electrically connected to av storage battery S through a suitable relay switch. .Any suitable pump, such as a gear or Gerotor pump F is connected to be driven by the motor E Yand associated with the pump F is a reservoir G. Since` the details of -construction and operation of the unit P form no part of the present invention, further description and illustra- `tion V,is not considered necessary.

` Sufiice it to say that the pump F through a conduit A forces liquid under pressure to the regulator mechanisms associated with the windows to be controlled, and liquid from such regulator mechanisms returns to the pump through a conduit B.

As will hereinafter appear, the conduits A and A,Bmay be said to be connected in series with the ,individual regulator mechanisms. with the several regulator mechanisms, and conlnected in the, return line B are control valve and V`switch units Cirespectively operated by the lever Associated L, the arrangement being such that upon manipulation of the leverL in one direction or the other, the electric motor E is energized and a Ivalve directs the flow of liquid under pressure to eiect upward or downward movement of the respective window panel. It will be observed that -leading from the relay switch on the electric mo- =tor E is a line D which extends to the several 'control units C, either directly or through branch `lines, the electrical connection being established by the manipulation of the lever L above mentioned.

As above mentioned, there is associated with each of the vertically movable window panels a regulator mechanism, and this is generally indi- Ylonger and the adjacentv ends of the grooves being separated by an imperforate wall 23. The outer ends lof the grooves are open to the interior of the housing substantially as indicated on i Figure 4.

As noted in cross section, the grooves 2l and 22 are formed with an enlarged shouldered cavity 24, a metal ring 25 seating on the shoulder and a rubber ring or gasket 26 bearing against the top of the metal ring. The shouldered cavity o1' groove 24 continues as groove 24 in the flat portion of the housing, the gasket 2li being shaped to fit in both grooves 24 and 24. A cover plate 21 which may be a stamping is bolted to the housing IS and slightly compresses the rubber gasket 2'6 to effect a liquid-tight seal.

Associated with the inner end of the grooves 2| and 22 are hollow bosses 28 and 29 respectively, to which hose lines 30 and 3| respectively are connected, thereby to admit liquid under pressure to one or the other of these grooves, and to enable'liquid to flow from the housing through the other of these grooves. The location of the hoses or tubes 3i! and 3! is not critical but the `position as shown is preferable due to the swinging movement of the housing, as will be hereinafter explained.

Pivoted concentrically of the arc of the housing i9 is an arm or vane 32 which consists of a stamped metal core 33 and a yieldable molded rubber enclosure 34. The core 33 has a hub 35 formed with a polygonal aperture 36 and the peripheral surface of the hub likewise is encased in a molded rubber sheath 3l. It is understood that the term rubber includ-es synthetic rubber and other similar materials having the desired characteristics of resiliency and flexibility .to achieve a fluid-tight seal with adjacent surfaces. Y

Attention is directed to Figure 9 showing the formation of the molded rubber enclosure or Sheath 3s. It will be noted that the sheath is provided at opposite sides with elongate flanges 38 extending from the hub of the vane to the Youter end thereof which slidably contact or engage the bottom wall of the housing I9 and the cover 27. Intermediate the anges 38, the sheath is slightly spaced from the adjacent surfaces.

Manifestly when the anges are subjected to liquid pressure, they impinge against the adjacent surfaces to form a liquid-tight seal, but such impingement being in the nature of a line contact is not sufficient to militate against the swinging or rocking movement of the vane. Similarly, the hub sheath 31 is formed with flange projections 39 to effect similar sealing engagement With the flat bottom Wall of the housing I9 and the cover 21 respectively.

Also projecting from the periphery of the hub .sheath 3l are flanges 40 having V-shaped grooves,

three of such flanges being shown, and these serve to effect a liquid-tight seal With the notched portion I9a (Figur-e 4) of the relatively straight Wall portion of` the housing I9. It will be recognized that the principle involved in connection with these rubber sealing sheaths is the same as that employed with flexible gaskets used to employ a liquid-tight seal between two rela- .is rockable upon a` pin .well .to a 'convenient horizontallyrom the' Ion'icketV 4,3 ilto'an adjacent door or `body panel, fasthe case ,may

one lead to the switch unit 83 is grounded and the -other lead D connects to the lead or wire DV (Figure 1) ,thereby to energize the electric motor E at any time that the acuating pin 82 is depressed. The arrangement is such that in the intermediate or oi position of the arm I6, the switch is 01T so that the electrical circuit is broken. Upon movement of the arm 76 in one direction or the other from its intermediate or oi position, the cam surface 853 causes the actuating element 82 to be depressed, therebytorrender the switch effective for energizing the electric motor E.

The outer end of the actuating arm 76 is connected by a rod or link 8f3 to the free end portion of a control arm 85 which is xed to a shaft 86 on the opposite end portion of which is fixed the actuating lever L which is, as above mentioned,

arranged on the inside of the door accessible for manipulation` It has hereinbeiore been pointed out that among the advantages of this window regulator system is the feature by which simultaneously one or another windowv may be actuated in an upward direction, one or more other windows actuated vin a downward direction, and still another window or windows retained inthe position of adjustment. Thus it will be observed that this system resembles the ordinary hand crank regulators by which several occupants of an automobile may simultaneously open and close their adjacent windows. So far as I am aware, this is a distinctly novel feature in interconnected power operated window regulator mechanisms. The diagrammatic view on Figure 16 illustrates this feature. Y

In that gure, three regulator mechanisms are schematically shown, referred to generally as R1,

R2 and R3. As indicated by the position of the vanes and the respective arrows, the vane in regulator R3 is moving in a counterclockwise direction to move the window to which it is connected in a downward direction. The vane of regulator R2 is swinging to the right or in a direction to move the window upwardly toward its closed polsition. However, the regulator R1 shows its vane in an intermediate position, indicating that the window is in its midway position and no movement is being imparted to it. It is to be understood that the window movement with respect to regulators R2 and R3` is taking place simultaneously.

Considering rst the regulator R3, its valve is so positioned that thearcuate groove 1| connects the ports 65 and 66. The port 65 isconnected by a tube or hose'l3 to the regulator housing channel 22 and the port 66 is connected by a tube 87 to the port 63 of the valve associated with the regulator R2. Liquid under pressure delivered by the pump F through the tube A enters the valve through the port 68 and since the valve groove I2 connects the port 68 with the port t9, liquid thenpasses from the port 69 to a tube S which communicates with the groove or channel 2| in the regulator R3, thus to cause the vane to swing in a clockwise direction.l Liquid is Vforced by the vane in regulator R3 from the regulator R3 then Vfrom the channel 22, tube 3|3, port 65, disc groove R2 through the tube 3|2 and through the channel 22 to actuate the vane of the regulator R2 in a counterclockwise direction so that upward movement of the window panel associated therewith is effected. The liquid on the right side of the vane of regulator R2 passes therefrom through the channel 2| and the tube 3l2 and enters theA respective valve through the port 69 which is in communication through the groove 1|' with the port 6E. The port 65 communicates through a tube 88 with the port SS of the valve associated with the regulator R1. However, this valve unit is in its onf position in which the valve groove 12"l communicates with the groove 67a which enables liquid under pressure from the tube 38 to pass through the groove 61a to the valve groove 1| which communicates through the return tube B to the pump F. Thus when the valve is in the oi position, no liquid under pressure passes to the associated regulator unit since the ports 65 communicating with the regulator unit through the tube 3| and the port 69 communicating with the regulator unit through the tube 3@ are not uncovered by the valve disc.

lnon armature shaft 9| which carries a sleeve 92 having a pin which rides in a longitudinally elongate slot S3. By energizing the electromagnet 89, the arm l5 is swung upwardly and by energizing the electromagnet the arm is rocked downwardly through the armature QI and connections described. The electromagnets 89 and '90 are suitably operated by a switch generally indicated at dfi, as will. be readily understood.

A unitary assembly is shown on Figures 18 to 20, in which a regulator unit as above described may be mounted in its entirety in the window well or other suitable location for window panel movement. rEhe regulator unit R is similar to that above described, so that detail description thereof is not considered necessary. In this form, a metal strip S5 has a pair of spaced outward embossures, and the end portions are secured by rivets to the adjacent door or body structure. In this instance, the stud on the'arm tia rides in a horizontally elongate slot el in one of the embossed portions, and instead of the housing being mounted on a Xed pivot, it likewise is provided with a stud 98 carried by an arm ed rigid with the regulator housing, and which rides in a horizontally elongate slot lll@ in the other embossure of the strip 95. The arms 51a and ila, as above described, have studs riding in horizontal slots or guides in retainers depending from the window edge embracing channel 54a.

A metalstrip 'lill is disposed in vertical posiammo tion to lie betweenfthe-outwardly-'extending embossures, dowirwardly.v extending; flangesA H32Vv in that region abutting against' the 5, strip' 95:3 and being securedtheretoby rivets. The. ends of the strip are formed with ilanges l'which are secured to-the adjacent supportby rivets. Az vertically elongate guide -slotl04is-formed inthe strip l el guidingly -to receive af buttonorstud H35 =which isnxed tothe regulator R, andin this instance .consti-tutes an integral extension o'f the operating shaft-onwhich-the vane is mounted. It will be manifest-thatduring vertical movement of the window, the-slottedstripel-Ell operates as a guide to cause the window to move in a vertically dened path. It will be apparent that an advantage of this structure is that at the factory, the regulator and its mounting parts can be assembled so that as delivered to the automobile or body company, it is only necessary for the assembly to be located in the desired position and riveted in place. This obviates difliculties caused by improperly locating the regulator mounting plates hereinbefore described. The vertical guide strip militates against binding of the vertical side edges of the window panel in their guides.

Although the regulator mechanism has been described particularly in connection with the actuation of vehicle window panels, it is to be understood that it can advantageously be used for the actuation of other parts which have to and fro movement between two limits of adjustment, such, for example, as automobile seats, tops for convertible automobiles, hoods and rear deck lids. Itis further to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as dened in the appended claims.
