Abstract: 1501951 Bearings ALLIS-CHALMERS CORP 23 Sept 1975 [25 Sept 1974] 38958/75 Heading F2A A journal bearing comprises at least three pivoted bearing pads arranged arcuately to support a journal 12 thereon and disposed symmetrically about a vertical plane passing through the bearing axis, each pad being mounted for pivotal movement on a supporting surface disposed radially outwardly of the respective bearing pad, some of the pads 20B, 20C each having a supporting surface which is radially fixed, and the remaining pads 20A, 20D each having a supporting surface which is radially adjustable and which is provided with an adjusting mechanism 27A, 27D for effecting individual radial adjustment of the supporting surface whereby the radial loads carried by all the pads can be equalized. Where the total number of pads is even, the fixed pads are disposed in the centre of the group and the adjustable pads are disposed towards the sides. Where the total number of pads is odd, an adjustable pad is located in the centre with a fixed pad on each side, any remaining pads being adjustable ones. Each pad is provided with a passage for the introduction of high pressure hydraulic fluid to the bearing surface, the source of fluid for each pad being separate and hydraulically isolated from the sources for the other pads. The method of setting up the bearing comprises the steps of adjusting the adjustable pads so that the fixed pads 20B, 20C accept most or all of the radial load, supplying hydraulic fluid to the pads, and adjusting the adjustable pads to accept some of the radial load and until the fluid pressure of each supply system to the pads is the same. Once the journal is running, low pressure fluid is supplied through grooves 34, 36 in the bearing surface of each pad. Each of the adjusting mechanisms comprises a wedge underlying a corresponding supporting surface, a bolt being provided to move the wedge longitudinally. To facilitate the sliding movement of the wedge, lubricant distribution grooves are provided in the surfaces of the wedge.

A retainer member 12 is disposed adjacent each wheel 6, 7 and each member is of arcuate form having a larger radius than that of the wheels to form a nip at the work station. Each wheel has a radially extending projection which engages a groove 3 on its associated retaining member. The drive means consists of a disc 15 which has a surface of friction material, such as sponge rubber faced with hard rubber, and is rotatable on the shaft 8 between the carrier wheels by an electric motor or the like. The tool consists of a paint roller and dip tray or, as shown, a shaped drum 25 which has an abrasive covering and is mounted on a shaft 26 carried by bearings on slide blocks mounted in the retaining members 12. The float blanks are fed by a hopper to the carrier wheels and are guided laterally by rails 80, 80a, as they are carried to the nip between the wheels and drum, the blanks being rotated on the carrier wheels by the disc 15. In another embodiment, the friction disc 15 is replaced by a belt (60, Fig. 3, not shown) driven over rollers (61...64) and having a surface of friction material.

In a baking oven for bakery products, or for reheating food or like purposes, hot air is circulated by means provided with openings which move in an endless path, there being at least one moving opening at each side of the product space, the arrangement being such that moving hot air currents are formed which issue from the openings at opposite sides of the space and travel over the products being heated. In the arrangement shown, two rotors 48, 48A are provided at the lower ends of vertical ducts 45, 46 which are supplied at their uper ends with hot air by a fan 37 which withdraws air from the product space 20, and forces it through a heat exchanger, comprising tubes 29 heated by a burner 34, to a chamber 41 with which the upper ends of ducts 45, 46 communicate the hot gases are collected from the upper ends of the tubes 29 in a flue including an inverted funnel portion and a chimney 32. Each rotor comprises a pair of diametrically opposed hollow arms 49, 50 secured to a hollow hub 47 which is journalled on a flange surrounding an opening in the wall of the respective vertical duct, the hub carrying a ring with sprocket teeth 52 by which it is driven from a motor 57 via an intermediate shaft 54, belt 55 and a respective sprocket chain 53. Adjustable openings 61, each provided by a fixed flange 62 and an adjustable flange 63, to control the air flow, are provided in each of the arms, the flanges extending at an angle to the axial direction, as shown, and further similar openings 65 are provided in the hub 47, excepting that the fixed and adjustable flanges 66, 67 forming the latter openings are directed axially. Slots are provided in the arms and hub to communicate the hot air from the opening in the wall of the vertical duct to the openings 61, 65. The two rotors 48, 48A are arranged so that the arms of one rotor are at right angles to those of the other, so that the products are impinged upon alternately by hot air currents from opposite sides of the space 20. Air is withdrawn from the space 20 via openings 73, 74 and two others (75, 76, Fig. 7, not shown), and also via a lower receiving duct 70, into a chamber 42 communicating with the inlet of fan 37. The products to be baked or heated are supported on a conventional wheeled rack 21 two of which are pushed into the space 20 in sequence, the movement of the racks being guided by tracks 23, 24 in the oven floor along which the wheels of the racks run.

[Also in Division E2] In an umbrella in which the supporting pole A, B can be arranged centrally or outside of the perimeter of the cover, the cover supporting frame C consists of stretcher ribs 8 pivoted at 9 to a notch 10 and bracing ribs 11 pivoted at 12 to a collar 13, and at 14, to the stretcher ribs, the frame being slidable on the pole part A which is formed of members 1, 2, 3 connected together by hinge joints 4, 5. The pole part A is securable by either end to pole part B which consists of a tubular member 6 having a screw connection 33, and a telescopic part 7 locked in groundentering position by a locking ring 21 as disclosed in Specification 915,923. As shown in Fig. 1, the frame is slid on to pole member 1, the collar 13 and bush 18, with locking screw 19, abutting end stop 15 and the hinge joint 4, when broken, retaining the notch 10 with the frame erected. The joint 5 is of the kind having rigidly locked positions as disclosed in Specification 944,829. A loose sleeve 17 prevents turning inside out of the cover resulting from too close approximation of the notch and runner. To convert to a centrally supported umbrella, as shown in Fig. 4, the pole part A is reversed, the joint 4 being locked in axially aligned position by the bush 18, the notch 10 abutting end stop 16 and the collar 13 being secured in a position to maintain the cover open by a stick spring 20 in the pole part 3. The umbrella may be secured by guy ropes and without the pole part B the umbrella can be carried in the hand. As shown in Fig. 5 the member 1, at one end, has a spring-urged ball 20 in a bore 25 and fork ends 26 carrying a pivot pin 29 for a tongue 28 on the member 2, the ball engaging a recess 27 to retain the members 1, 2 in aligned position during erection collapsing or conversion, and, at the opposite end, has a plug 30 bored at 31 and with a threaded portion 32 to receive the screws 33 and tip 34 on the pole member 6. As shown in Fig. 8 the spring catch 20 extends from a plug 35 through a slit 36 in the pole member 3 and is retracted by the tip 34 of the pole member 6 which pushes a rod 38 and deflector 37 to allow free running of the frame on the pole for conversion. The notch 10 carries a sealing ring 23 to prevent the passage of rainwater between the notch and the pole.
