Title: Improvements in axle boxes with needle bearings
IPC: B61F15/12
Filed: 1934-02-17
Abstract: 433,623. Axle-boxes; lubricating. PITNER, A., and SOC. ANON. DES ROULEMENTS A AIGUILLES, 34, Boulevard de l'Yser, Paris. Feb. 17, 1934, No. 5288. Convention date, Feb. 21, 1933. [Classes 12 (i) and 12 (iii)] A railway-vehicle axle-box 2 with needle roller bearings 4 has a lubricating disc or ring 6, which functions as an axial thrust member, secured to the journal, this disc or ring being in sliding contact with co-operating plates or rings 13, 14 rigid with the axle box, arranged on opposite sides of the disc 6. The two sets of needle roller bearings 4 may have a common race 5, or separate interlocked races. The lubricating disc 6 is non-rotatably mounted on the journal 1 by means of keys, dogs, flats, eccentric parts or the like and secured thereon by a nut or equivalent device 7. A projection on a rib 9 of the disc 6 mates with the end surface of the race 5 so that the latter is also non- rotatable on the journal. Similar locking means may be employed between the race sections when the race is sub-divided, and between the race 5 and a ring 11 or a shoulder 12. The thrust plates 13, 14 may be fixed to the box or its cover 3 or may be integral with either. Oil picked up by the disc 6 from a reservoir 15 is scraped from it by a scraper 16 and passes to the needle bearings through passages 17, 18, returning to the reservoir by way of the chamber 19 and channel 20. The inner races may alternatively be forcibly and permanently driven on to the journal.

Filed: 1925-02-26
Abstract: 245,307. Armstrong, J. J. V., (Union Special Machine Co.). Feb. 26, 1925. Sack-sewing machines. - The sewing-head is mounted to be traversed on a bracket arm extending from a standard and means are provided for automatically reversing its motion after sewing up a sack so as to bring it back to the starting point. The motor is mounted independently of the sewing head and is stationary. A sleeve 3 slidable on a column 1 carries a bracket 12 from which project tracks 39, 40. The sleeve and bracket are counter-balanced by a weight 5 the connecting cord 6 making several turns round a pulley 7 which may be rotated by a hand-wheel 11 to raise and lower the sleeve. A screw-threaded shaft 18 is mcunted between the tracks 39, 40 and is driven in alternative directions by a motor 13 mounted in the bracket 12 and having a pulley 14 over which pass direct and crossed belts 15, 16. These belts run over pulleys 17, 19, freely rotatable on the shaft 18 and arranged to be alternatively clutched to discs 22, 23 fast on the shaft, the requisite movement of the pulleys being effected by a yoke 24 operated by an arm 25 stressed by a spring 30 to move the pulley 19 normally into engagement with the disc 23. A flexible connection 31 is attached to the arm 25 and is operated by a treadle 34 to move the pulley 18 into engagement with the disc 22. A rod 28 carrying stops is connected to the arm 25. The sewing-head, which is of known construction, is mounted on a truck having four wheels 48 and a depending lug 59 with a threaded orifice 60 which engages the thread of the shaft 18. A pulley 65 for driving the sewing mechanism is mounted in a recess 61 in the lug 59 and is driven in one direction only, through a roll clutch 71 operated by a sleeve 62 splined to the shaft 18. The sleeve is held in position by a nut 64 which abuts against a hub portion 66 of the sleeve. A belt 73 passes over the pulley 65 and over a driving pulley on the sewing head. The sewing-head is moved outwards from the column to stitch a sack unti a stop 78 on the carriage engages a stop on the rod 28 to move the rod in a direction to shift the clutch mechanism and reverse the rotation of the shaft 18 so that the sewing-head is returned to starting position.

Title: Intermittent drive mechanism
IPC: F16H29/02
Filed: 1963-02-09
Abstract: 1,062,643. Ratchet gearing; slip couplings. DAWSON BROS. Ltd., G. DAWSON, and D. DAWSON. Feb. 6, 1964 [Feb. 9, 1963], No. 5378/63. Headings F2Q and F2U. In an intermittent drive mechanism, e.g. for imparting stepped motion to a conveyer carrying bottles past washing jets, a pawl 4 and a claw 10, fixed together and pivoted to a regularly oscillating arm 6, respectively engage a ratchetwheel 3 and a mask wheel 11 which has alternate shallow teeth 12 and deep teeth 13 whose combined pitch equals the pitch of the ratchet teeth 5, so that as the pawl and claw oscillate through a distance slightly greater than the ratchet tooth pitch, on alternate working strokes a shallow tooth 12 acts on the claw 10 to lift the pawl 4 clear of the ratchet teeth 5, the ratchet wheel 3 thus being advanced by one tooth pitch only on alternate working strokes. The ratchetwheel 3 is bolted to a collar (2) keyed to an output shaft 1, while the mask wheel 11 is rotatably supported on the collar (2) adjacent the ratchet-wheel. A slip coupling (Fig. 4, not shown) comprising adjustably spring loaded pads (14) in the ratchet-wheel (3), and backing pads (16) on the collar (2) acts on the mask wheel (11) so that it rotates on the collar (2) only when driven by the claw (10).

Title: Improvements in infinite step controlling device for compressors
IPC: F04B49/02
Filed: 1961-02-14
Abstract: 926,214. Regulating compressors; reciprocating pumps. INGERSOLL-RAND CO. Feb. 14, 1961 [March 3, 1960], No. 5507/61. Classes 8(1) and 102(1). The inlet valve 18, Fig. 1, of a reciprocating compressor driven by a constant speed motor or engine 20 is held open during an infinitely variable portion of the compression stroke by a spring-returned hydraulically actuated unloader plunger 228, 236, Fig. 3, to which pressure oil is supplied by a rotatably mounted reciprocating plunger pump 24 driven by the engine and from which unloader plunger oil supply is interrupted thereby allowing seating of the inlet valve 18 which occurs when the degree of rotation of said plunger 128 is such that a helical groove 161, Fig. 8, therein registers with a spill port 170; said rotation being effected through a rack and pinion gear 42 driven by a diaphram motor, when the latter is subjected to a compressed air reservoir pressure below a predetermined level and transmitted through a pressure regulating valve 46 and ducts 51, 96. The beginning of the delivery stroke of the pump plunger 128 is timed to coincide with that of the compressor piston 16 but at said diminished reservoir pressure oil is discharged through the spill port 170 and is thus denied access to the unloader plunger which is thus held by its spring 246 in its retracted position to allow the inlet valve 18 to close at or some time after the beginning of the compressor delivery stroke according to the degree to which the reservoir pressure has fallen. The pump plunger is driven forwardly by a cam 32 secured to the engine shaft 30 and abutting a ball bearing 150 and is returned by a spring 172. Rotation of the plunger is effected by engagement of a key lever 142 thereof with longitudinal slots 140 cut in a casing 124 having external teeth 132 meshing with teeth 134 of the rack 136. Assuming the spill port to be covered pressurized oil is forced past the seat 198 of an adjustable check valve 184 into the casing of an adjustable relief valve 36 from which oil surplus to the capacity of the chamber 218 of the unloader plunger passes through a duct 266 to the oil supply reservoir 34. A reverse check valve 202 prevents air bubbles from entering the hydraulic plunger chamber 218. In a modification the pressure regulating valve 46 is connected to the intake manifold of the engine 20 instead of to the reservoir 44 whereby the pressure output from said regulator will vary and operate the diaphram motor 40 accordingly which in turn controls the rack and pinion gear 42.
