Abstract: 419,127. Drilling-machines. SCHOENING, H., 23, Franziskanerweg, Frohnau, Berlin. -(Assignee of Raboma Maschinenfabrik H. Schoening; 51, Spandauerstrasse, Borsigwalde, Berlin.) May 8, 1934, Nos. 13916 and 13917. Convention dates, May 10, 1933 and Dec. 27, 1933. [Class 83 (iii).] In a radial drilling-machine the rotatable carrier for the drill-head arm is clamped by the axial movement of a ring or ring segments, brought into frictional engagement with a corresponding ring or ring members. One method of clamping the sleeve b, carrying the radial arm, to the column a, is by moving the ring-shaped wedge k in an axial direction consequent upon the rotation of a toothed ring g which engages pinions on the ends of spindles e screwing into the wedge. A number of segments simultaneously operated by means similar to the above may be used in lieu of a single ring k and the form of the clamping members may be varied, in one modification a ring member is forced downwards on to a shoulder to effect the clamping. Another method of moving a wedge member k, Fig. 7, is by means of a series of levers r, Fig. 6, having cam grooves engaged by rollers t carried by a rack and pinion-operated sleeve g ; the levers have a toggle action on links e connected to the ring member.

Title: Improvements in or relating to variable speed transmissions
IPC: F16H3/66
Filed: 1944-07-25
Abstract: 594,950. Change-speed epicyclic gear; friction clutches. BORG-WARNER CORPORATION. July 25, 1944, No. 14204. Convention date, July 8, 1943. [Class 80(ii)] Two reduced forward speeds, directdrive and one reverse, are obtained from two three-element epicyclic trains 13, 14, driven from a driving shaft 10 through a nested double main-clutch 15, 16, by means of which the drive can be applied selectively to either the sun wheel 23 of the first train through a one-way roller clutch 35, or to the integral planet carrier 22 of the first train and ring-gear 24 of the second. The integral first ring gear 20 and second carrier 27 are fixed to the driven shaft 11. For the lowest speed, in which both trains take part, the friction-clutch 15 is engaged to drive the sun 23 of the first train, and a brake 33 is applied to the sun 26 of the second train. For second speed, the brake 33 and friction-clutch 15 remain engaged, but the friction-clutch 16 is also engaged to drive the ring-gear 24 of the second train, which latter acts alone in this speed, the one-way clutch 35 between the clutch 15 and first sun 23 overrunning. Directdrive is by engaging a cone-clutch 18 between the first carrier 22 and sun 23 to lock the gearing solid. A one-way clutch 31 between the second sun 26 and its brake 33 overruns in this speed, and the one-way clutch 35 also overruns, the brake 33 and both clutches 15, 16 remaining on. Reverse is by engaging the clutch 15 and a brake 34 on the carrier 22 of the first-train which latter is effective alone. The main-clutches 15, 16 are engaged against spring-pressure by hydraulic pressure applied selectively to annular pistons 38, 45 respectively, which press the driven friction discs 51, 52 against a common central plate 50 through plates 39, 46 urged apart by common springs 49. Pressure is supplied through ports 56, 60. The direct-drive cone-clutch 18 is engaged by spring-pressure 19 and disengaged by hydraulic pressure, applied to a piston 77 through the hollow shaft and a supplyport 81. On a vehicle, to facilitate starting the engine by towing the vehicle, a reversely-acting one-way clutch 91 is arranged between the driving-shaft 10 and an aligned intermediate shaft 12, which carries the first sun 23 and the direct-drive clutch-cone 18. With the engine running, the ratchet-sleeve 91 of the one-way clutch is held out of action by oil-pressure acting on a piston 97, but with the engine stopped, absence of oil-pressure permits a spring 94 to advance the ratchet-sleeve 91 into engagement with teeth 92 on the driving shaft 10 and also permits engagement of the direct-drive cone-clutch 18 by its spring 19, so as to establish a direct-drive from the driven shaft 11 to the driving shaft 10 in the forward direction for engine-starting. Cushion springs 65 are provided in the drive to the nested clutches 15, 16.

Abstract: 444,232. Coin-freed apparatus. BOON'S PATENTS, Ltd., and BOON, S. J. L., 57, Palmerston Road, Boscombe, Hampshire. May 15, 1935, No. 14275. [Class 27] Coin action, mechanical - connection and multiple-coin.-In coin-freed apparatus having a rotary operating-member or shaft 10, a disc 13 fixed to the shaft 10 is normally locked by a detent 14 engaging a shoulder 15 on the disc after this is given a limited rotation. To free the disc, two coins are inserted, the first 43 passing through a slot 36 in a fixed plate 35 and resting on the edge 41 of a slot 39 in a slider or coin-interceptor 38. The second coin 44 rests on top of the first coin and is located in the lower portion of the coin guide 25 between two pivoted plates 26, 27. The plate 26 has a cam 33 engaged by a roller 34 on the disc 13 to rock the plate against the action of a spring 30, thereby causing the coin 44 to rock plate 27. The detent 14 is pivoted to the plate 27 and is thus withdrawn out of the path of the notch 15. A spring 32 normally holds the detent in contact with the periphery of the disc 13. A second notch 23 limits the rotary movement of the disc 13 and a spring-pressed pawl 17 coacts with teeth 16 on the disc to ensure a full-stroke. The mechanism may be arranged to take a single coin, or more than two. Coin-discharging mechanism.-A tail piece 45 on the detent 14 engages a recess 46 in the slider 38 and moves the slider to allow the coins to drop, when the detent is released. Clearing-apparatus, autonaatic.-An arcuate projection 47 on the disc 13 actuates a lever 48 which is operatively connected by a flexible link with a coin detector mechanism to reject defective coins at the commencement of rotation of the main shaft 10.
