Abstract: 527,255. Vehicle opening-tops. BRIGGS MANUFACTURING CO. April 5, 1939, No. 10629. Convention date, April 16, 1938. [Class 108 (i)] An aperture 16 in the front or rear part of a vehicle roof 15 is adapted to be opened and closed by a slidable panel 23 the edges of which, when closing the aperture, are in substantially the same plane as the edges of the roof defining the aperture and are separated therefrom by resilient means 27 adapted to be compressed in a horizontal direction between the edges. As shown, a channel-shaped gutter member 20, Fig. 8 is secured to flanges 17 formed by bending down the edges of the roof at the sides and rear of the aperture, the edge of the roof at the front of the aperture having a raised bead 18, Fig. 2, bent to form an inclined flange 19. At the front of the aperture the gutter merges into a sub-panel 21, Fig. 5, which with the portion 22 of the roof forms a pocket for receiving the panel 23. The panel consists of an upper metal sheet 25, Fig. 8, having a bent strip 26 secured thereto to hold a rubber sealing strip 27 firmly against the flanges 17, the panel being guided in tracks in the gutter members by rollers 31 mounted in inverted V-shaped retainers 32 fixed to angle brackets 32a secured along the sides of the panel. The rollers are maintained on the tracks by resilient flanges 35 formed on channel strips 33 secured to flanges 34 on the gutter members. In order to guide the front edge of the panel into the aperture-closing position and into the pocket 50, rollers 38 are mounted in stepped formation in the tracks for engagement by the front rollers 31, and rollers. 40, Fig. 2, are mounted in the middle of the rear edge of the sub-panel 21 for engagement by a shoe 41. The forward edge of the panel is formed with a channel 42a containing a rubber strip 42 which presses against the edge of the flange 19 on the bead 18 when the front end of the panel is raised by the rollers 40 and shoe 41. Movement of the panel is effected by a handle 43 which also operates means for locking the panel in any position, the means comprising a crank disc 44, Figs. 11, 12 to which are pivoted the inner ends of bars 45, the outer ends carrying friction wedges 46 adapted to be pushed into clearance spaces between strips 47 on the panel and the top surfaces of the strips 33. The wedges when in locking position also bind the rollers 31 against movement between the flanges 35 and the bases of the gutter members 20.

Title: Improvements in hydraulic brakes for engine testing apparatus
IPC: G01L3/20
Filed: 1953-04-21
Abstract: 724,846. Fluid friction brakes. HOFFSTROM B. N. April 21, 1953 [April 22, 1952], No. 10898/53. Class 103 (1). A hydraulic brake or dynamometer for testing aircraft engines and the like comprises a brake housing, a brake disc mounted to rotate in said housing, an annular chamber surrounding said brake disc and adapted to contain a brake fluid through which a portion of the brake disc is adapted to rotate, which includes a fluid exhaust chamber arranged adjacent the outer portion of the annular chamber but substantially separated therefrom and a narrow passageway connecting the outer portion of the annular chamber with the fluid exhaust chamber substantially throughout the circumferential length of said chambers. The hydraulic brake 10 is supported upon and by a mounting frame 11. A brake disc 12 is mounted to rotate with a supporting shaft 13 which is in turn driven by the engine through shaft 21 and a step-up gearing transmission 20. Carried on the shaft 13 is a blower fan 18 for cooling the engine. Inner housing members 25 and 26 form a brake fluid chamber 29 in which a portion of the brake disc 12 is adapted to rotate and the brake fluid, preferably oil of high viscosity, is also contained in reservoirs 34, 35 within the outer housing members 16, 17 and supplied with brake fluid through conduits 36, 37. The braking capacity of the brake can readily be increased or decreased by increasing or decreasing the amount of brake fluid within the chamber 29. An annular fluid exhaust chamber 40 surrounds the inner fluid chamber 29 opposite the peripheral edge of the brake disc 12 and connecting the fluid exhaust chamber 40 with the inner brake fluid chamber 29 is an annular passageway 45 made up of two annular adjoining concentric passageways 46 and 47. The narrower passageway 46 reduces the velocity of the brake fluid removed from the brake prior to said brake fluid coming into contact with any obstruction that would form an abutment that might be abraded or worn by the high velocity fluid. By the time the brake fluid reaches the wider section 47 of the composite passageway 45, its rotational velocity will have decreased substantially to a zero value, whence it enters the annular fluid exhaust chamber 40 and is passed through an exhaust conduit 43 for reconditioning by cooling. Two alternative constructions of the passageway 45 are described to achieve the same'object.

Title: Improvements in or relating to levers, go-through and other lace machines
IPC: D04C3/24
Filed: 1945-05-02
Abstract: 654,620. Lace machines. SAILLY, R. May 2, 1945, Nos. 11200 and 11201. Convention dates, April 20, 1944, and Nov. 23, 1944. [Class 74 (i)] A Levers Go-through or other lace machine has its thread guide-bars 4 disposed between the channel 3, Fig. 2, and the goosenecks or the usual plates or beams and their longitudinal displacement, relative to the necessary displacement of their respective threads at the carriage level, is increased by adding a supplement determined by the number of gates existing , between the attaching-point in the nails and the gate to be occupied at the carriages multiplied by the ratio of the distance between the carriages and bars and the distance between the attaching-point and the level of the carriages. Bars disposed at the same distance from the carriages as the attaching-point 0, as shown in Fig. 2, or twice or three times the distance, are operated by means of droppers corresponding to an even number of gates whilst for bars located intermediately, halfdroppers and fractional-droppers are introduced. The machines may have several stories of bars and each bar, which may be of arcuate section, may have three lines of holes, Fig. 6 (not shown), to permit correction of local defects. The bars may be connected to the Jacquard at the desired level by means of rigid members 6, Fig. 7, having vertically-arranged rows of holes 7 and provided with a screw for adjustment purposes. In machines having a multiple motion for the nails or points the attaching- point corresponds with the position of the nails when the bars are operated. The machine may be controlled by a Jacquard having a cycle of four motions, the four cylinders working alternately. Specification 6377/14, [Class 74 (i)], is referred to. The Specification as open to inspection under Sect. 91 also contains tables and diagrams relating to various movements of the bars and positions of the threads at the attaching-point and in the channel. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to transmission mechanism
IPC: F16H3/54
Filed: 1932-04-20
Abstract: 388,244. Variable-speed gearing. SIFTON, C., 1212, Canada Permanent Building, Bay Street, Toronto, Canada. April 20, 1932, No. 11346. [Class 80 (ii).] Variable - speed gearing comprises aligned driving and driven shafts 1, 2 and a loose central epicyclic element 5 subjected to two frictional drags, a clutch drag tending to turn it with the shaft 2 and the resistance of a brake disc 17 which is prevented from turning backwards relatively to a fixed casing 19 by a pawl detent 20. Planet pinions 7 on a frame 6 fast on the shaft 2 mesh with an annulus 4 on a drum 1 fast on the shaft 1 and with the sun gear 5, which thus tends to rotate freely backwards. On both , sides of the brake disc 17 are discs 9, 10 splined on a boss 8 of the gear 5, and outside the discs 9, 10 are a friction ring 13 fast on the annulus 4 and a pressure disc 11 splined on the shaft 2. The disc 11 is normally held by a spring 23 pressed to the left so as to clutch the parts together, effecting solid driving. As the thrust of the spring 23 is counteracted by increasing manual thrust exerted rightwardly through a shifter 29 and another spring, slipping of the clutch and brake discs takes place reducing the speed of the shaft 2 eventually to zero. During this process, the gear 5 is at one time kept from turning backwards by the brake and detent, and so forms a fulcrum by which the torque on the shaft 2 is increased.

Title: A slewing and luffing jib crane
IPC: B66C23/10
Filed: 1957-04-08
Abstract: 814,504. Tower cranes. LIEBHERR, H. April 8, 1957 [April 6, 1956], No. 11389/57. Class 78 (4). A slewing and luffing jib crane in which the jib is mounted on a mast, and substantially level luffing is achieved by inserting a tackle in the load-hoisting line between the mast-head and the jib-head, has means to prevent the jib being accidentally over-luffed by the tension in the load-hoisting line. As shown the jib 12, Fig. 1, is luffed by a cable 13, and the load cable 25 has three runs between the jib head and the head of a tower 10 on the mast 7. A cable 30 is attached to the jib head and to a truss 31 pivoted at 11, and passes over pulleys 32, 33 before being attached to a pivoted counter-jib 34 carrying ballast 35 and supported by cables 36. The cable 30 is slack until the jib approaches a dangerous inclination, after which the ballast 35 counterbalances the jib as shown in dotted outline in Fig. 1. Alternatively the same effect may be achieved by spring means between the jib and the tower 10. Speed of movement of load.-The horizontal speed of the load is made substantially constant during luffing by using a conical or conical differential luffing drum. In the latter case the luffing cable 58, Fig. 6, passes from the drum 57 to the jib head via the top of the tower 10, then back to the drum by the same route, and is wound in the opposite direction round the other end of the conical drum, as at 59, Fig. 6. A constant linear speed of the load during slewing is obtained by an infinitely variable gear 63, controlled from the luffing shaft 65 through a belt or chain 64, in the drive to the slewing pinion 81. Since the variable gear is of a type which must be continuously rotated while varying, a magnetic clutch 80 is included in the slewing drive so that the slewing motor can be rotated, without necessarily slewing the crane, whenever the luffing motor is operated. Instead of the conical differential luffing drum 57 a cylindrical drum may be used, driven through an infinitely variable gear such as that shown at 63. Erection of the crane.-Erection about a pivot 68, Fig. 7, is achieved by a cable 74 which passes from the hoisting drum 73 and several times between pulley blocks 71 on a pivoted truss 70 and 72 anchored to the ground. Cables 77 connect the truss 70 to an anchorage 75 on the mast. The crane may be made mobile by mounting the mast sections 1, 2, 3, Fig. 1, above the rotating part 7, the whole being supported on a trolley.
