Title: Improved winding device
IPC: B66D1/36
Filed: 1949-05-06
Abstract: 670,037. Uniform winding apparatus. KARLSSON, P. T. May 6, 1949. No. 12137/49. Class 78 (v). An apparatus for effecting an even distribution of a rope on a winch drum, is characterised in that said apparatus comprises a hollow externally threaded shaft, a runner member carrying guides for the rope and engaging with and carried by said threaded shaft so as to move there-along to guide the rope to the drum when.said threaded shaft rotates, a second and axially-displaceable shaft positioned parallel to said threaded shaft and having flanges fixed thereon which effect the axial displacement of said second shaft when said flanges are engaged by said runner member, a gear fixed on said threaded shaft, a driving shaft, a clutch member slidably but not rotatably mounted on said driving shaft, two pinions in alternate engagement with said gear and rotatably arranged on said driving shaft and adapted to be engageable with said clutch member so as to be driven by said driving shaft, an inner shaft rotatably journalled in said hollow threaded shaft and driven by said second shaft, an eccentric or the like on one end of said inner shaft to move said clutch member axially along said driving shaft into engagement with one or the other of said pinions and means to engage said second shaft with said driving shaft to effect a connection between said second shaft and said driving shaft in each of the two end positions of said second shaft so as to drivingly connect said clutch member respectively with said pinions. Figs. 1, 2. Runner 2 carrying guide rollers 3, 4, 5 is traversed by threaded shaft 1 and guided by smooth shaft 7. Its reversal is caused by stops 8 and 9 fixed on shaft 7. When the runner 2 strikes the left stop 8, shaft 7 is displaced axially to the left. Threaded shaft 1 is driven from driving shaft 11 through sleeve 12 (which is axially displaceable thereon and rotatably fixed thereto), through right sleeve 13 which is coupled to sleeve 12 by claws 24, 25, and through gear 10 fixed on the threaded shaft. The threaded shaft in turn drives the runner 2. Thus, the latter strikes stop 8 and displaces the stop and therefore the shaft 7 to the left. This causes temporary engagement between divided tooth ring 20 and threaded wheel 18 fixed on driving shaft 11 so that shaft 7 is rotated and the drive is then passed through gear 28, belt 27, gear 26 and shaft 15 mounted internally of shaft 1 to pin 16 eccentrically mounted on said shaft 1. Pin 16 is therefore displaced and, engaging in a slot slotted in sleeve 30, displaces said sleeve 30 so that it contacts a flange 31 and disengages sleeve 12 from right hand sleeve 13 and engages with left hand sleeve 14. The drive now passes from driving shaft 11 through left hand gear 14 and runner 7 therefore reverses and moves to the right.

Title: Improvements in and relating to vaporizing systems for internal combustion engines
IPC: F02M31/12
Filed: 1931-04-24
Abstract: 385,959. Treating liquid fuel supplied to direct injection engines. SCHIMANEK, E., 1, Horthy Miklosstrasse, Budapest. April 24, 1931, No. 12161. Convention date, April 25, 1930. [Class 7 (iii).] Liquid fuel before its admission to the engine cylinder is heated under pressure, the degree of heat being automatically regulated so that the temperature of the fuel closely approaches but does not exceed its boiling temperature. In the construction shown in Fig. 2, a pump 1 delivers fuel through a valve 3 into a pipe 4 which is heated by an electric coil 8, the current passing through the coil being controlled by a rheostat the contact arm of which is connected to a centrifugal governor. The fuel is withdrawn from the pipe 4 by an injection pump 13 which feeds the working cylinder 6. According to a modified construction the pump 13 also draws air from the atmosphere or from the engine cylinder to form a fuel-air mixture. In the construction shown in Fig. 4, the coil 8 heats a liquid in a chamber 171 which surrounds the fuel admission pipe 4. When an excess of heat is supplied the liquid is vaporized in the chamber 17<1> at a pressure determined by a spring 18a and displaces a piston 18 which is connected through a lever 19 to a regulating device 21. The pump plunger 1 is actuated during its forcing stroke by a spring 1a which is adjusted in relation to the spring 18a so that the boiling point of the liquid fuel is the same or higher than the boiling point of the liquid in the chamber 17<1>. According to a further modification, Fig. 5, the heating coil 8 is dimensioned to correspond to the maximum load and the springs 1a, 18a are relatively adjusted to maintain a higher pressure in the pipe 4 than in the chamber 17<1> so as to avoid the generation of vapour in the fuel pipe. The excess heat supplied to the liquid in the chamber 17<1> is dissipated by passing the vapour through a pipe 17a into a vessel 23 having a cooled surface 23a on which the vapour is condensed. According to another construction, shown in Fig. 6, the fuel acts as the heating liquid and a higher pressure is maintained in the pipe 4 than in the chamber 17<1> ; acting on one side of the piston 18 is the pressure in the pipe 4 and on the other side the pressure in the chamber 17<1> and the spring 18a. The excess heat supplied to the chamber 171 is dissipated by condensation of vapour on the cooled surface 23a of a vessel 23. In the construction shown in Fig. 7, the pump delivers fuel into a reservoir 24 from which branch the pipes 4, 17b and 23 ; the same pressure is established in the pipe 4 and in the chamber 17<1>, and the vapour generated in the chamber 17<1> is condensed in the pipes 17a, 23.

Title: Readily removable shaft cam construction
IPC: H01H19/62
Filed: 1956-04-23
Abstract: 809,162. Securing cams to shafts. DANLY MACHINE SPECIALTIES Inc. April 23, 1956 [April 21, 1955], No. 12282/56. Class 80 (2). [Also in Group XXXVII] An arrangement of cams 50, 52 on a shaft 46 is such that the cams can be adjusted circumferentially on the shaft, or can be readily removed therefrom and replaced by cams of different shapes. The shaft 46 is formed with an axial keyway 66 which receives radial keys 64 rotational connecting spacers 68 to the shaft. The spacers 68 are in frictional engagement with the flat faces of spacers 48, the opposite faces of which are formed with ridges 60 and projections 58. Each ridge 60 engages in a corresponding recess 62 in a cam such as 50, Fig. 4, and each projection 58 engages between the ends of a forked slot 54 in the end of the cam. The spacers, cams, &c. can be frictionally held together by tightening a recessed nut 78 threaded on the shaft 46 to compress a spring 82. The outsides of the spacers 48 are provided with graduated scales 106 co-operating with index marks 108 on the spacers 68. To adjust a cam 50 or 52 relative to the shaft 46, the nut 78 is slackened off to release the pressure of the spring 82. The cam is then turned relative to the shaft, the positive connection 58 &c. between the cam and the spacer 48 causing the latter to turn relatively to the spacer 68, itself positively connected to the shaft by its key 64; movement of the index mark 108 relative to the scale 106 thus allows the angle through which the cam is turned with respect to the shaft to be determined. To replace a cam 50 &c., the nut 78 is slackened off, as before, the desired cam slipped off the shaft, and another slipped on in its place. The arrangement is described as applied to a rotary switch, suitable for use with a power press to control automatically the points in the press cycle at which various operations take place. Arms 72 surround the spacers 68, which are allowed to rotate freely relatively to the arms. The arms 72 support switches 100 actuated through roller and link mechanisms , 90, 94 by the rotating cams 50, 52. The arms 72 and switches 100 can be. adjusted rotationally a limited amount relative to the shaft 46 in a stationary housing 10, and are locked in position by clamping means 104.

Title: Shaft positioning clutch device
IPC: F16D71/04
Filed: 1957-04-18
Abstract: 810,075. Stopping shafts in predetermined positions. COLLINS RADIO CO. April 18, 1957 [Sept. 25, 1956], No. 12763/57. Class 80 (2). A coupling device between a driving member and an output shaft comprises a jamming roller-type ratchet clutch surrounding a torquelimiting clutch on the output shaft, the cage for the jamming rollers being formed with a raw-toothed shoulder and the output shaft having locking means controlled by a first pawl which co-operates with a second pawl engageable with the sawteeth, friction means having substantially less torque capacity than the clutch being provided between the driving member and the roller clutch cage. Drive from a cylindrical driving member 41 is transmitted to an output shaft 11, required to be positioned in predetermined positions, through a roller ratchet clutch comprising the bore of the driving member 41, rollers 51 in a cage 36 and a collar member 21 having flats 22 on its periphery. The bore 23 of the collar 21 is splined to engage plates 28 of a torque limiting coupling whose intermediate plates 27 are splined to the output shaft 11, the coupling being axially loaded by a spring washer 29 and circlip 31 in a groove 32 of the shaft 11. The cage 36 for the clutch rollers is formed with a saw-toothed shoulder 38 and a light frictional drag between the member 41 and the shoulder 38 is provided by a felt washer 47. The shaft 11 extends through a support plate 10 and has a notched stop-wheel 17 fixed to the end 16, the notches 64 of the wheel 17 being engageable by a pawl 63 pivoted on a spindle 62 and actuated by a relay 66. A second pawl 71 pivoted by a slot 72 on the spindle 62 is engageable with the saw-tooth 38, the pawl being loaded laterally by a spring 76. During normal running the drive from a gear 46, integral with the member 41 is transmitted to the shaft 11 through the roller clutch and the torque limiting coupling, the two pawls 63, 71 being held disengaged by the relay 66. When the shaft 11 has been rotated to a desired position the relay 66 is de-energized and pawl 63 drops into a notch 64 to lock the shaft 11, this produces slip in the coupling 27, 28 for a small part of a revolution until the pawl 71 drops behind one saw-tooth of the flange 38. Pawl 71 then moves the length of the slot 72 until it abuts the pivot 62, whereupon the pawl produces disengagement of the roller clutch and stops the torque loading on the coupling 27, 28. As the roller clutch releases, the spring 76 acting through the pawl 71 moves the roller clutch cage into a mid-position of non- engagement such that the member 41 rotates freely with only light friction between it and the shoulder 38. This light frictional drive is used to engage the roller clutch on re-engagement of the drive by energizing the relay 66. In a second embodiment two saw-tooth shoulders are provided of opposite hand to provide drive in either direction. Specification 660,939, [Group XXXVIII], is referred to.
