219,073	Jul. 14, 1924	Improvements in Steam Boilers	Thomas L. Aveling	, England	Abstract: To facilitate assembly, the firebox end-plates a and the shell plates e are first jig drilled and machine finished, and the plate c forming the firebox crown and sides is riveted to the bent-over edges of the end-plates, the firebox and shell plates are then riveted to the bottom frame f, holes are bored in both set of plates, and stays g are screwed into the holes and riveted. The roof plate h has machined edges and is riveted to the front and side plates of the shell and to the barrel. Stay bars q of T-section are secured to the roof and front' plates.
240,932	Oct. 12, 1925	Improvements in Oil Burners	Thomas L. Aveling	, England	Abstract: A spray burner comprises three concentric passages, the inner and outer passages 1, 2 being supplied with steam or other gas through ports 3, 4 and the intermediate passage 5 being supplied with fuel through a port 6. An outer casing 14 provided with air-admission ports 15 surrounds the burner nozzle. The steam issuing from the passage 1 is regulated by means of a needle valve 7 formed on the grooved end of a rotatable central rod 8 which screws into a cone 9 at the end of the passage. The outlet end of the passage 2 preferably consists of a number of slots 13 arranged at such an angle as to cause the steam to issue in convergent whirling jets. The fuel passage 5 is preferably annular and converges at its discharge end.
250,327	Apr. 09, 1926	Improvements in Apparatus for Use in the Treatment of Roads	Frederick W. Smart	, England	Abstract: e of keying the surfacing material consists of a spiked cylinder 1 adapted to rotate freely on a shaft 2 carried in a frame 4 slidably adjustable with respect to a second frame 6 attached to the rear of the road roller. In the form shown, the frame 4 is raised and lowered by a handwheel 8 driving a worm gear which rotates a pinion 13 engaging a rack 14 on the frame 4. The spikes 16 are screwed to permit of adjustment in the roller 1.
321,814	Nov. 21, 1929	Improvements in Actuating and Variable Timing Means for the Fuel Pumps of Oil Engines	Louis P. Croset	, England	Abstract: Actuating by toothed gearing; timing-devices.- The fuel pump for an internal-combustion engineis driven through spiral gearing. A gear wheel c firmly mounted on the engine camshaft or other shaft b gears with a wheel d mounted on a splined portion of a shaft a which drives the fuel pumps. The boss of the wheel d is grooved at k to receive a fork j, so that the wheel d may be moved relatively to the wheel c thus angularly displacing shaft a relatively to shaft b, and varying the timing of the fuel pumps. An idle spiral gear wheel may be employed.
325,505	Feb. 19, 1930	Improvements in or Relating to Devices for Starting Internal Combustion Engines	Louis P. Croset	, England	Abstract: A friction driving- member b is rotatable in a housing e pivoted at its ends in a part f of the casing of the engine fly-wheel a and is rotated by means of an annular gear q coaxial with the member b and a pinion r coaxial with the pivot of the housing, so that the pivotal movement of the housing, to bring the driving member b into frictional engagement with the fly-wheel, will not interfere with the rotary movement of the driving member. The housing is turned about its pivots by means of an arm K and the shaft s of the pinion r is driven by an electric, petrol, or air-driven starting-motor, or by a fly-wheel 'set in rotation by manual or electric means.
328,687	May. 05, 1930	Improvements in or Relating to Apparatus for Delivering Measured Quantities of Liquid	Clifford M. Wilcock	, England	Abstract: In an apparatus for delivering measured quantities of liquid, particularly suitable for use in conjunction with concrete mixers, a pivotallv mounted measuring vessel 3 is dipped into a constant level reservoir 1, and the liquid passes into the measuring vessel through a flap valve 9. The quantity of liquid to be withdrawn from the reservoir is determined by limiting the downward travel of the measuring vessel by an arm which bears against an adjustable stop. To discharge the liquid the vessel 3 is turned about its pivotal axis to an inverted position and empties into a trunnion 5 which may communicate directly with a suitable discharging nozzle. The level in the reservoir is maintained constant by a float-controlled valve.
364,034	Dec. 28, 1931	Improvements in the Road Wheels of Road Rollers	Francis A. Perkins	, England	Abstract: A wheel for road rollers is built up from steel plates secured to a hub and forming a hollow structure for the reception of concrete or like ballast. The wheel shown comprises side plates 2, 3 welded to the rim 1 and lapped plates 4, 5, the hollow wheel body being fitted with concrete &c. 6. Plates 7 may be fitted across the rim and one of the side plates to prevent shifting of the filling material.
364,168	Jan. 04, 1932	A Variable Speed Drive for Road Rollers, Tractors and the Like	Francis A. Perkins	, England	Abstract: Comprises the combination of a frame 1a, a. slow or medium speed internal-combustion engine 1 mounted thereon, a gear-box 4 also mounted on the frame and driving the road wheels, and an endless flexible member such as 5 transmitting the drive from the engine shaft 2 to the primary shaft 3 of the gear-box, the said primary shaft being driven at or above the speed of the engine. In the construction shown the shaft 3 is driven by the chain 5 at engine speed, but the sprockets 6, 7 can be readily changed so that the shaft 3 may be driven at a higher speed. The chain passes over a jockey pinion 8<1>, and it may be enclosed. The last shaft 8 of a change-speed gear in the gear-box drives a shaft 13 through reducing gear 12 and the shaft 13 drives the road wheels through a single reducing train 14, 15.
365,180	Jan. 18, 1932	Improvements in Road Rollers	Francis A. Perkins	, England	Abstract: A saddle bracket or steerage head for road rollers is built up from mild steel or other metal plates and is provided with a tube forming a bearing for the vertical shaft or post. A bracket of box section may be formed by welding together two channel-shaped members 1, 2, a vertical tube 6 being welded in apertures. The upper end may be closed by bending and welding the members 1, 2, and the lower end by welding on a plate 9. The chamber thus formed may be used as an engine silencer or as a container for fuel or water, inlet and outlet openings 11, 12 being provided with welded seating rings or washers 13, 14. The plate 9 may be provided with an inspection opening 15 normally closed by a cover-plate secured by screws fitting into apertures 16. The bracket is secured on the frame by nuts or bolts passing through holes 17. In a modification four plates are welded together to form a box-section bracket.
369,280	Mar. 18, 1932	Improvements in or Relating to Safety Devices for Internal Combustion Engines Having Forced Feed Lubrication	Francis A. Perkins	, England	Abstract: In apparatus wherein the fuel supply is cut off by a valve upon failure of the pressure of the lubricant supply, a dashpot is provided to delay the operation and manual or foot operated means are provided for opening the valve. A plunger 12 is subjected to the lubrisating-oil pressure passing through passages 13, 14 and is provided with a recessed part 25 which permits the flow of fuel through the passages 15, 16 in the position shown. The plunger has a head 19 which slides in a cylinder closed at the bottom by a plug 22 and open at the top to the fuel passage 15 through a restricted passage 21, or through a non- return valve 29 with restricted passages 30 in its body or in the valve seat. The head 19 is recessed to receive a spring under compression. When starting, a lever 28 engages a rod 17 secured to the plunger and depresses it. The plunger rises slowly owing to the dashpot until the pressure of the lubricant arrests it. Should the pressure fail, or build up too slowly, the fuel supply will be cut off.
394,403	Jun. 29, 1933	Improvements in or Relating to Internal Combustion Engines	Charles W. Chapman	, England	Abstract: A spherical or cylindrical combustion c'hamber 7, formed in either the cylinder head or the piston, is connected to the cylinder by a short tangential passage 11, along the axis of which the liquid fuel is injected. The passage 11, the diameter of which is less than a quarter, and preferably slightly less than a sixth, of the cylinder bore, may be formed in a screwed-in plug 9, the upper wall 12 of which is as thin as possible compatible with strength; a shallow depression 13 overlaps the mouth of the passage 11. If the combustion chamber is cylindrical its axis is either horizontal or vertical, and in the latter case the passage 11 is eccentric and inclined as shown in Fig. 11, where the combustion chamber is in the cylinder head and the passage mouth overlaps the edge of the cylinder bore.
