Title: Hydraulic device having a hydraulically balanced commutator valve
IPC: F04C2/10
Filed: 1969-09-09
Abstract: 1281374 Power steering TRW Inc 9 Sept 1969 [10 April 1969] 44463/69 Heading B7H [Also in Division F1] An hydraulic device that may be a part of a steering system has a gear member 19 arranged to revolve about its own axis, which is fixed, and mesh with a planetary gear-member 20 controlled by gear teeth 26, 27. The flow of working fluid to and from pockets between the gear members is controlled by a rotary valve 21 and plate 22 connected to the member 19 by a shaft 24. Passages 50<SP>1</SP>, 5011 and corresponding passages 31, 34 in a housing 11 for a further valve 18 are interconnected by passages 49<SP>1</SP>, 49<SP>11</SP>, radial recesses 51<SP>1</SP>, 51<SP>11</SP> and annular grooves 47, 48. The hydraulic forces acting axially on the walls of the grooves and those of the recesses in the valve 21 are balanced. The valve 18 is coupled to the shaft 24 by splines 54 so as to be slidable axially and has a pin 28 engaging with an oblique slot in a rotary shaft 24a, which is linked with the shaft 24 by a torsion rod 62. When a steering wheel (not shown) joined to the shaft 24a by splines 127 is turned clockwise the valve 18 shifts to the left from the neutral position shown, the torque transmitted by the rod 62 being insufficient to turn the shaft 24. Connection is thus made between the expanding pockets and the pressure side of an external pump (not shown) by way of annular grooves P<SP>1</SP>, 56, M 1  and between the contracting pockets and one end of an hydraulic cylinder, for operating the steering linkage, by way of annular grooves M, 57, C 1 <SP>1</SP>. The other end of the cylinder is connected to the suction side of the pump by way of annular grooves C<SP>1</SP>, 58, a passage 59, the interior of the shaft 24a and an annular groove R<SP>1</SP>. Fluid pressure in the expanding pockets rotates the gear member 19 in the same direction as the steering wheel, rotation continuing until the valve 18 has been returned to its neutral position. The rod 62 ensures complete return to said position. Counter-clockwise motion of the steering wheel effects actuation of the system in the opposite sense. If the pump fails, overlapping ends of the shafts 24, 24a interconnect the steering wheel and the gear member 19.

Patent GB-453348-A (GB)
Abstract: 453,348. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. Feb. 9, 1935, No. 4218. Convention date, Feb. 9, 1934. [Class 106 (i)] Printing totals and sub-totals.-In a cash register or similar accounting-machine having direct total-printing mechanism controlled by one or more locks for sub-total and total taking operations, the actuating member for effecting the total-printing may perform only a single operating stroke after a sub-total lock has been opened, and after the opening of a total lock or locks the actuating member is prevented from making more than one printing stroke until the totalizer has been reset. The invention is described as applied to a machine of the kind forming the subject-matter of Specification 439,118, wherein sub-total-taking is controlled by a lock 11, and total-taking by a lock 12, while printing is effected by a counterclockwise rocking of a lever 29. The opening of the sub-total lock 11 now releases the printing lever 29 for a single printing movement, return movement of the lever being prevented until the lock has been reclosed. Moreover, the opening of the total lock 12 followed by the insertion of the reset key into an opening 13 releases the printing lever for a single printing movement prior to the resetting movement of the key. The printing lever 29 is normally locked by a spring-urged lever 25, a lug 26 on which engages above a shoulder 27 on the lever. However, upon the opening of the subtotal lock 11 the locking lever 25 is rocked counterclockwise to ineffective position by a lever 22 connected to the bolt of the lock through a link 19, lever 17 and stud 14. The printing lever, thus freed, is rocked operatively counterclockwise under the control of a fullstroke device and is held in rocked position by a spring-pressed latch 31, the left-hand edge 51 of which takes behind a stud 33 on the lever. The latch remains operative to lock the printing lever until the lock 11 is reclosed when it is disabled by the clockwise restoring movement of the locking lever 25, and permits the printing lever to return under the action of its spring 52. The opening of the total lock uncovers, in known manner, the opening 13 into which the reset key is inserted. A lever 68 is rocked upwardly by a bevelled portion of the inserted reset key and through a stud on a link 70 rocks the lever 22 to release the printing lever. Rotation of the reset key is prevented until printing has been effected, a shoulder 72 on the latch 31 being normally in locking position relative to a projection on the key. Main-shaft control.-The main shaft 43 is locked by the counter-clockwise rocking of a lever 39 when a machine lock 45 is closed, when either of the sub-total and total locks 11, 12 is opened and when the total-printing lever 29 is out of normal position.
