POWER OPERATED MEANS AND CONTROL MECHANISM THEREFOR Filed Sept. 18, 1942 4 Sheets-Sheet 4 W0 Q 594 V INVENTOR Q VVAIJER FER'E'IS Patented May 25, 1948 I POWER-OPERATED MEANS AND CONTROL MECHANISM THEREFOR Walter.Ferris, Milwaukee, Wis., assignor to The Oilgear Company, Milwaukee, Wis., a corporation of Wisconsin Application SeptemherlS, 1942, SerialNo. 458,889 I This invention relates to control mechanisms of the'type in which a single device is employed to control a plurality of mechanisms.
For the purpose of illustration, the invention will be explained as employed to control the turret traverse mechanism and the firing mechanisms of an army tank but the invention is not limited to such use as it may readily be employed for controlling other mechanisms.
In a tank to which the invention is applied, the turret is rotated by a traverse mechanism to aim the guns carried by the turret, the guns are fired by electro-magnetic mechanisms and the traverse and firing mechanisms are controlled by a single control device.
The invention has among its objects the provision in a control device of the above character movable elements for efiecting operation of at least one mechanism, stationary switch means for eifecting operation of at least one electromagnetic mechanism, and instrumentalities movable with the movable elements for operating the stationary switch means so that the use oi. flexible cables or sliding electrical contacts is avoided. Other and more specific objects and advantages of the invention will appear from the description hereinafter given of the control mechanisms shown in part schematically in the accompanying drawings in which the views are as follows:

Fig. 8 is a schematic plan view showing the invention applied to the turret of a tank.
Fig. 9 is an elevation partly in section showing a modification of the device shown in Fig. 1.
Fig. 10 is a top plan view of the device shown in Fig. 9.
Fig. 11 is a view taken on the line II--II of Fig. 9.
For the purpose of illustration, the invention has been shown applied to a tank turret in Fig, 8 from which all devices not associated with the invention, such as the oil reservoir, gun stabilizer and stabilizer pump have been omitted to avoid complicating the view. The turret I has a plurality of guns such as a cannon 2 and a machine gun 3 suitably mounted therein and adapted to be aimed at a target by rotating turret I by means of a pinion I driven by hydraulic motor 5 through a reduction gear 6. Motor 5 is energized .by liquid supplied thereto through two pipes I and 8 from a reversible variable delivery pump 9 mhich is continuously driven by an electric motor Pump 9 may be similar to the pump shown in Patent No. 2,406,138 to which reference may be had as to the construction and operating characteristics thereof. It is deemed sumcient to state herein that pump 9 will deliver liquid in a direction and at a rate dependent upon the direction and distance its control. lever II is moved from its neutral position and that, when lever II is in its neutral position, pump 9 will be at zero stroke and no liquid will be delivered thereby.
' Figs. 1-7
As shown in Fig. 6, lever I I has a hub I2 formed thereon with its face in engagement with the face of a hub I3 formed upon a flange I4 which is fixed in a stationary position as by bein fastened to the casing of pump 9. Hub I2 is fixed upon the outer end of a shaft I 5 which extends through hub I3 into pump 9 to operate the stroke changing mechanism thereof as fully shown and described in Patent No. 2,406,138.
Hubs I2 and I3 are encircled by a torsion spring I6 the opposite ends of which are arranged upon opposite sides of two pins I1 and I8 fixed, respectively,'in lever II and in flange I 4 so that spring I6 tends to hold pins I1 and I8 in radial alinement with shaft 1 5 in which position of pins I1 and I8 the pump control mechanism is in neutral and no liquid will be delivered by pump 9. When lever II is rotated in one direction or the other from its neutral position. shaft I5 will operate the pump control mechanism and cause pump 8 to deliver liquid in. one direction or the shaft 26 as shown in Fig. 1. Shaft 25 is journaled near its lower end in the lower end of a tube 21 fixed to or formed integral with a bracket 28 which is attached to a wall of turret l as indicated in Fig. 8. Shaft 28 is Journaled near its upper end in an annular projection 28 formed upon the lower end of a housing 30 and fitted within bracket 28 which is bifurcated along one side.
thereof and provided with a bolt ii for clamping housing 80 in an adjusted position. The upper end of shaft 26 has a bevel gear 82 fixed thereon and arranged within housing 30 in mesh with a bevel gear 33 fixed upon a horizontal control shaft 34 which has one end journaled in a bearing 35 and its other end iournaled in and extending through a bearing 88 formed upon a wall of housing 30.
For the purpose of illustration, shaft 25 has been shown in a vertical position in order to simplify the views but in practice shaft 28, projection 29, bracket 28 and tube 21 extend downward and laterally at an angle from the axis of horizontal shaft 34 in order that the control mechanism and the turret traverse drive may be suitably arranged within the limited space available within turret l.
Three normally open electric switches 40, 4| and 42 are supported, as by means of a bracket 43, within housing 30 and connected into an electric circuit by conductors (not shown) extendin through a thimble 44 arranged in the cover 45 of housing 30, the three switches having one terminal of each connected together by a bus bar 45. As shown in Fig. '7, switches 40 and 4i control two solenoids 41 and 48 respectively, and switch 42 functions to out switches 40 and 4| into and out of the electric circuit. Energizing one or the other of solenoids 41 and 48 effects operation of the firing mechanism of one or the other of guns 2 and 3.
The upper ends of actuators 49, 50 and 5| are urged, respectively, by springs 53, 54 and 55 against a stop bar 56 carried by bracket 43. The lower ends of actuators 49, 50 and 5| engage, respectively, three push rods 51, 58' and 58 which are slidable in horizontal shaft 34. Push rods 51- and 58 extend through suitable longitudinal slots formed in the peripheral surface of shaft 34 diametrically opposite each other and push rod 59 extends through a suitable bore :formed upon the axis of shaft 34 as shown in Fig. 5.
Operation Handle 65 (Figs. 1 and 2) is normally held in its central or neutral position by the action of spring I 6 (Fig. 6). When handle is swung in one direction or the other through a certain angular distance in a vertical plane, it will rotate shaft 34, gears 32 and 33 will rotate shaft 25, and lever 25 on shaft 26 will cause rod 23 to swing pump control lever H in a direction and through a distance corresponding to the direction and distance handle 55 is moved from its neutral position. Moving lever II will cause pump 9 (Fig. 8) to discharge liquid in a direction and at a rate determined by the direction and distance lever II is moved from its neutral position. The liquid discharged by pump 9 will flow to motor 5 and cause it to rotate turret I through reduction gear 8 and pinion 4. Turret l is thus rotated in a direction and at a rate determined by the direction and distance handle 65 is moved from its neutral position.
As the turret approaches the positionin which the guns are directed toward the target, the operator gradually returns handle 65 toward its neutral position, thereby reducing the speed of the turret until the guns are aimed directly at the target at which time the speed of the turret can be regulated to the speed of the target and/or the speed of the tank, or the turret can be stopped if the target is stationary or is moving directly toward or from the tank or if the tank is moving directly toward or from the target.
The operator, by squeezing the grip portion of handle 55, may swing lever 16 upon pivot 11 and cause it to swing lever I2 upon pin 13 and move rod 59 axially of shaft 34-. Rod 59 will swing actuator 5i upon shaft 52 and cause it to close switch 42 to thereby connect switches 40 and 4! into the electric circuit.
Then when the guns are aimed at the target, the operator may place his thumb upon and depress either or both of pads 14 and 15 to swing either or both of levers ill and ll upon pin 13 and move either or both of rods 51 and 58 axially of shaft 34 so that either or both of actuators 48 and 50 are swung upon shaft 52am! close either or both of switches 40 and 4| to energize either or both of solenoids 41 and 48 and thereby cause target.
' Figs. 9 to 11 The device shown in these figures differs from the device shown in Figs. 1 to 5 only in the means for transmitting motion from the control handle to the pump control lever. Consequently like parts have been indicated by like reference numerals and further description thereof is deemed unnecessary while corresponding parts have been indicated by corresponding reference numerals with the exponent 12" added to the numerals applied to such corresponding parts in Figs. 9 to 11.
The firing and safety switches are arranged within a housing 3i! which differs from housing 30 in that it is connected at its bottom to a bracket 28 by means of which it may be attached to the turret. Housing 30 has Journaled therein a shaft 34 which differs from shaft 34 in that gear 33 is omitted therefrom and whichhas the control handle 65 fixed to its outer end.
The control operates in exactly the same manner as the control shown in Figs. 1 to 5 except for the manner in which motion is transmitted from the control handle to the pump'control lever.
