Title: Improvements in and relating to fluid-pressure engines
IPC: F01L7/02
Filed: 1934-04-09
Abstract: 436,165. Fluid pressure engines. BROWN, F. H., Broadmead, Sweetcroft Lane, Hillingdon, Middlesex. April 9, 1934, No. 10603. [Classes 122 (ii) and 122 (iii)] The cylinders C<1>, C<2> of the uniflow type are surrounded by a high-pressure chest H supported in a low-pressure chest L and a rotary valve V controls flow of fluid from the chest H to the cylinders whence it is exhausted to a chamber W communicating with the low-pressure chest. The valve is axially slidable for reversing purposes, is chain driven from the crank-shafts J and is supported in a tube T having ports P connected by ducts D to the ends of the cylinders. Pressure fluid passes from the highpressure chest through inlets I in the valve to the interior of a sleeve A fixed in the valve, whence it passes through ports M<1> and P to the cylinder C<1>. The port M<1> is of triangular shape and its hypotenuse coacts with an inclined side of the port P which is in the form of a parallelogram to determine the cut-off. Adjustment of the cut-off is effected by axial movement of the valve. The port 14<1> co-operates alternately with ports P in opposite sides of the tube T for supplying opposite ends of the cylinder. Release is effected through a port Q which communicates with the space between the valve and sleeve A connected to the low pressure chest. Reversing inlet and release ports N<1> and Q<1> are brought into operation by axial movement of the valve. Ports M<2>, N<2> at the opposite end of the valve control fluid flow to the cylinder C<2>. Additional relief ports may be provided in the valve to enable the pistons to be moved freely by rotation of a shaft. The tube T may be made in two parts in which case the inlet ports I may be arranged between them. Two valves may be used and placed one adjacent each end of the cylinders.

Title: Improvements relating to roller and ball bearings
IPC: F16C33/30
Filed: 1943-07-01
Abstract: 564,342. Assembling ball and roller bearings. FISCHER BEARINGS CO., Ltd., and ELLIS, L. M. July 1, 1943, No. 10665. [Classes 83 (ii) and 83 (iv)] Rollers or balls, a cage, and one race ring are assembled to make an inseparable unit by contracting or expanding the cage without distortion after the parts have been placed in position. An annular cage 4 flanged at 5, Fig. 1, has pockets 6 that will only permit rollers 3 inserted from within to pass through to an extent sufficient to enable the flange 2 of the race 1 to pass. The cage is then supported in a groove 19 of die segments 14 having means 20 to receive the rollers and located by screws and washers 16 in slots of a plate 11 supported by a spring 13 and a rod 12, sliding in an outer die member 8. A spring ring 15 tends to separate the sections 14 which engage the member 8 by bevelled surfaces 9. A press applied to the dies effects the contraction of the cage so that the parts cannot then be separated. The size of the pockets may be such as to permit the rollers to be inserted from the outside, but the contraction of the cage reduces the size sufficiently to prevent the rollers from passing back. When the unit is to include the outer race, the cage 4 has then to be expanded instead of contracted and this is effected by die segments 14, Fig. 10, grooved to support the cage and expanded by a cone 23. The flanges of the cage may extend in either direction or may be dispensed with. Application to a ball bearing, in which the outer race is formed for subsequent lateral assembly, is described.
Patent GB-106684-A (GB)
IPC: D03C1/04
Abstract: 106,684. Boyd, W., Small, W., and Foster, J. June 3, 1916. Dobbies.-A sliding bar for each heald carries two separately pivoted catches, of which one is adapted to move the heald from its lowest to its highest position, where the other catch may retain it, while the second catch is adapted to move the same heald from its highest to its lowest position, where the first catch may retain it, the dobby thus acting to produce open-shedding; by suitable adjustment of the parts, the dobby may be arranged to effect close centre-shedding. Each jack-lever 2, Fig. 3, is connected by a rod 3 to a bar 4 slotted to slide on cross-bars 5, 5<a> and having two pivoted catches 6, 6<a> with weighted ends x, x<1> adapted to rest on projections 13<a>, 13<b> on feeler levers 13 pivoted at 13<c>. A peg 14<a> on the pattern chain 15 of the barrel 14 causes the catch 6 to be engaged by one draw-bar 7 of a pair of drawbars 7, 7<a>, which are guided by slots 8, 8<a> with inclined portions h, h<1> and are operated by cranks to move towards and from one another. When the bar 7 draws the catch 6 and the bar 4 in the direction of the arrow w, the corresponding heald is raised to its highest position, and the catch 6<a> is engaged by a stop-bar 16<a> to retain it until the absence of a peg under the lever 13 causes the outer end of the catch 6<a> to be lowered. The pattern surface indicates when the bars 7, 7<a> are nearest to one another, at which time bars 17, 17<a>, pivotally connected to the bars 7, 7<a>, are in the inclined parts h, h<1> of the slots 8, 8<a>, so that they act on projections 4<b>, 4<c> on the bar 4 to free the retained catch 6 or 6<a> from the pressure of the corresponding stop-bar 16 or 16<a>. The ends of the bars 7, 7<a> are connected by rods to duplex cranks 10, 11, Fig. 6, on a shaft 12, which is driven through bevel-gearing from a vertical shaft geared to one of the loom shafts, and clutch mechanism is provided to disengage the coupling, when desired, in order that the shaft 12 may be rotated by a hand-wheel and gearing. A pin-wheel driven from the shaft 12 may co-operate with a starwheel to drive the pattern barrel; or this may be rotated continuously. To adjust the dobby to produce centre-shedding, the bars 17, 17<a> are raised so as always to be in position to engage the projections 4<b>, 4<c> to close the shed, and the drawbars are moved only half their full distance in the horizontal parts of the slots 8, 8<a> by adjusting the duplex cranks 10, 11 to half-throw. For this purpose, an arm v of the crank 10 fits in a dovetailed groove in a projection k of a gear-wheel 22 on the shaft 12, and is secured in full or half throw position by bolts &c. m, and the crank-pin 11 is adjustable in a slot in an arm p.
