Title: Improvements in load-gear equipment for vehicle brakes
IPC: B61H13/32
Filed: 1944-06-26
Abstract: 578,174. Vehicle brakes. SVENSKA AKTIEBOLAGET BROMSREGULATOR. June 26, 1944, No. 12130. Convention date, June 21, 1943. [Class 103 (i)] Variable leverage brake mechanism for vehicles comprising a pair of equalizing levers by which the braking force is distributed to brakes at opposite ends of the vehicle, a third lever through which the force is transmitted from the brake cylinder or other power source to one of the equalizing levers and for which a shiftable fulcrum is provided for varying the leverage is mounted on a beam-like support so as to form a unit adapted to be secured to and beneath the transverse underframe members. Automatic means for shifting the fulcrum in accordance with the loading of the vehicle is described. Equalizing levers 4, 5 connected by pull rods 7, 8 to the brakes at opposite ends of the vehicle and linked together at 6 are connected to the piston rod 9 of the brake cylinder 3 by a lever 2 and link 10. The levers extend through a beam 11, 12 of box form to one side of which the cylinder 3 is secured. The' levers each comprise upper and lower members those of the lever 5 being disposed above and below a plate 20 and being pivoted thereto at 16 to provide a fixed fulcrum for this lever. A guide 22 is provided for the lever 4. A shiftable fulcrum 1 for lever 2 is slidable on.a guide rod 23. Casings 24, 25 and partitions 13, 14 fixed to the beam form a compartment for the lever 2 and its fulcrum 1 to exclude dirt. Means for adjusting the fulcrum 1 automatically in accordance with the vehicle load may also be carried by the beam and as shown is of known kind comprising a semi-elliptic spring 27 attached to slidable rods 31, 32 arranged for connection by pull rods 33, 34 to lever systems 35, 36 which transmit forces derived from the pressure on the bearing springs at the ends of the vehicle. The loading of the bearing springs being in general unequal, the rods 31, 32 are subject to opposite but unequal forces so that one or other of the connecting pins 28<1>, 29<1> at the ends of the spring 27 moves to the closed end of a slot in a member 28, 29, secured to the beam. The spring 27 is thus deflected to an extent dependent upon the pressure on the supporting springs at the least loaded end of the vehicle. This deflection is transmitted to the fulcrum 1 by a lever 37 which is connected thereto at 40, to the spring 27 at 39 and pivoted to the beam at 38. The pivot. 38 may be adjustable laterally. The beam with the parts shown in Fig. 4 thus forms a unit which may be attached to and beneath the transverse sills 46 of the vehicle underframe. The stresses arising in the parts carried by the beam, due to the braking force are taken wholly by the beam so that it is not necessary to brace the underframe for this purpose. U.S.A. Specification 2,204,925 is referred to.

Filed: 1920-05-05
Abstract: 166,003. Fairweather, W. C., (Underwood Typewriter Co.). May 5, 1920. Web and sheet feeding arrangements; linespacing mechanism.-In web-manifolding arrangements comprising means for straightening the loops lying on the platen-roller, a record-sheet receiving line spacing movement with the webs is automatically fed to separate the sets of entries when the webs are straightened. The invention is shown as applied to the arrangement described in Specification 23349/14 and comprising a platenroller 16 mounted in a frame 19 which is pivoted on a rod 20 on the carriage 12 and can be raised to separate the platen-roller from the feed-rollers 17, 18. According to the invention, the platenroller is provided at each end with a revoluble extension 22 which co-operates with a feed-roller 24 to feed a record-sheet of greater width than the webs when the frame 19 is raised. The feedroller 24 is carried by a lever 27, pivoted on the frame 19 and drawn upwards by a spring 26. The hook 31 for holding the frame 19 in the depressed position normally abuts on a finger 28 of the lever 27 and thereby holds the feed-roller 24 out of engagement with the extension. When the hook is pushed rearwards to release the frame 19 the spring 20 draws the feed-roller into engagement with the extension. The extension is provided with a ratchet-wheel 34 co-operating with a pawl 35 on an arm 37 which can rock on the platenshaft and is connected to a link 39 having a slot 40 engaging a pin 38 on the carriage. When the frame 19 is raised, the hook, after moving idly backwards and forwards, is detained by the pin- and the pawl abuts on the ratchet-wheel and causes the extension to rotate and feed the recordsheet. The ratchet-wheel has the same number of teeth as the line-spacing wheel and the feed of the record-sheet may be equal to two or three tooth intervals. The feed may be varied by altering the length of the slot 40 or the position of the pin 38. The spring 26 is connected to the arm 37 and is extended when the frame 19 is raised, the pressure of the feed-roller 24 being thereby increased. A detent 43 engages the ratchet-wheel 34. When the frame 19 is lowered, the spring returns the arm and pawl to the normal position, determined by a stop pin 44 on the journal 45 of the platen-shaft.
