Title: Improvements relating to the attachment of the blades to a turbine or compressor wheel
IPC: F01D5/30
Filed: 1957-04-18
Abstract: 807,186. Mounting turbine and compressor blades. GENERAL MOTORS CORPORATION. April 18, 1957 [July 19, 1956], No. 12712/57. Class 110 (3). [Also in Group XXV] In a turbine or compressor wheel in which blades are mounted by their roots in undercut slots extending axially across the rotor rim, means are provided to prevent endwise movement of the blades in the slots. Each blademounting slot 17 has in its base a socket 23 and each blade root 14 is formed with a transverse socket 24, also with a cut-away portion 28. Locking pins 21 are provided having a plate portion 26 secured thereto, the plate portion having a deformable tab 31 at the free end. The pin 21 is first inserted into the socket 23 at the base of the blade-mounting slot, the plate portion 26 lying on the bottom of the slot. The blade root is then inserted into the slot from the right, Fig. 2, the cut-away portion 28 passing over the projecting end of the pin 21 and the plate portion 26. The pin 21 is then moved radially outwardly by means of the plate portion 26 so that the outer end of the pin engages in the transverse slot 24 in the blade root, the plate portion 26 lying against the cut-away portion 28 of the blade root. The locking pin is held in this radially outward position by means of a rectangular support plate 32 disposed between the plate portion 26 and the bottom of the blade-mounting slot, the tab 31 of the plate portion being finally peened over so as to secure the support plate in position. Alternatively, the clearance necessary to permit assembly may be provided in the socket 24 in the blade root so that the pin would have to be moved radially inwardly into the socket at the base of the blade-mounting slot after assembly, the support plate in this case being disposed between the plate portion 26 and the blade root.

Title: Improvements in or relating to shaft-positioning mechanisms for setting a shaft in one of a number of predetermined positions
IPC: F16D71/04
Filed: 1957-04-23
Abstract: 833,043. Shaft - positioning mechanism. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 23, 1957 [April 25, 1956], No. 12927/57. Class 80 (2). In mechanism for positioning a shaft in a number of predetermined positions, the shaft 1 carries a number of locking rings 2 and concentric co-operating pawls 4 selected by a single selector wheel 7, the mechanism including a motor 13 having two directions of rotation A, B selected by a reversing switch 24, the motor driving through a self-locking gear two freewheel clutches 16, 17 such that in one direction of rotation (B) the selector wheel 7 is positioned and a pawl 4 selected, and in the other direction (A) the shaft 1 is rotated until the selected pawl co-operates with the locking ring, provision being made of a final switch 22 operated by the deformation of a resilient member 19, between the shaft 1 and the free-wheel clutch 17 driving the shaft, to control the final switching of the motor. Although the invention relates to rotary shaft positioning, the Figure shows translatory motion to facilitate the description. To set the shaft 1 to a predetermined position, a selector switch 26 is rotated to set the required position, this energizes the motor 13, through reversing switch 24 and seeking switch 9, to rotate in direction B so that shaft 15 is moved to the left. When the shaft 15 has moved a distance C, allowed by a stud 34, the free-wheel clutch 16 is driven to move the selector wheel 7 to the left, while the shaft 18 remains stationary and the spring 19 is enabled to expand and carry with it the switches 21 and 23, the switch 21 is, however, carried by the stationary shaft 20 and is therefore closed. When the seeking switch 9 reaches the corresponding point the switch 24 is de-energized and returns to the reverse position by the action of spring 24a. The motor then rotates in direction A driving the shaft 18 directly through free-wheel clutch 17 until the new pawl drops into the appropriate locking ring 2 and prevents further rotation of the shaft 1. The spring 19 is compressed and the final switch 22 is opened to stop the motor. Since the motor drive is locked the spring 19 maintains a loading in the drive direction on the shaft 1 to eliminate backlash. This loading is released on the next operation due to the clearance angle C on the clutch 16. In a modification the rod 20 may be connected to a coarse-pitch screw and nut mechanism to operate the switch. The spring 19 may be a fluid buffer or a rubber or synthetic resin resilient device. Specification 653,419 is referred to.

Title: Improvements in and relating to arrangements for balancing the disturbing forces in balancing machines
IPC: G01M1/04
Filed: 1937-05-06
Abstract: 474,519. Balancing forces in machines. SCHENCK EISENGIESSEREI UND MASCHINENFABRIK, DARMSTADT GES., C., and OHLY, C. May 6, 1937, No. 12994. [Class 80 (iv)] [Also in Group XIX] Relates to machines in which counter forces produced by masses on an auxiliary shaft at a constant distance from the shaft, can be adjusted while in motion to effect balance and consists in providing that the supporting means for the auxiliary shaft can be turned so that the effective component of the constant centrifugal force of the masses is changed in accordance with the amount of turning motion. The disc 1, Fig. 1, is provided with an unbalanced mass 2 and rotates about an axis 6 which is held in position by a link 3 and bar 4. The end of the link 3 can be adjusted along a track 5 and fixed at any point, while the bar 4 leads to the oscillating part of a balancing machine. Movement of the disc under the centrifugal forces of the mass 2 can only occur in the direction AB and as this motion can only to taken up by the bar 4, the latter moves under the component of the force in the direction of the bar 4. This varies from " zero " when the link 3 is in line with the bar to the full amount when the link 3 is at right-angles to the bar 2 and this may, by varying the position of the end along the track 5, be used to equalize the disturbing forces of the balancing machine. In a modification, instead of the end of the link 3 being adjustable in a slot, it is pivotally carried in a fork supported by a linkage which may be adjusted angularly. In the form shown in Figs. 3, 4, the disc 9 with eccentric masses 10 is rotatably mounted in a frame 15 and driven by a bevel gear 11, 12 through a flexible shaft. The frame 15 is pivoted in a stirrup 16 pivoted about an axis 17 and connected to the part 19 of a balancing machine. In the form shown in Fig. 5, each standard 21 of a balancing machine has pivoted thereto a transverse member 23 supported by a spring 24. The rotor 25 to be balanced is carried as shown and the disc 28 with eccentric masses is mounted to rotate in a frame 27 pivoted to the other end of the member 23. Here, the centrifugal force is a maximum when the plane of the disc is vertical. The direction of the rod-work transmitting the counter force to the machine may be displaced to effect balance in a similar way..
