INTERNAL GOMBUSTION LIQUID PUMP.
AIPLIGATION FILED MAY 16, 1911.

EDWARD BYNES BADCOCK, OF LONDON, ENGLAND.
INTERNAL-COMBUSTION LIQUID-PUMP.
Application filed May 16, 1911. Serial No. 627,544.
'and Ireland, residing at 7 Pembridge Crescent, London, England, have invented new and useful Improvements in or Connected -with Internal-Combustion Liquid-Pumps,
of which the following is a specification.
This invention relates to the production of an improved type of internal combustion liquid pump operating on a propulsive and a reactionary stroke cycle.
According .to this invention the propulsive stroke, which isI produced by the ignition of a charge of combustible mixture acting on the liquid (hereinafter referred to as water) which is impelled and caused to acquire momentum, comprises an initial pressure portion and a completing induc` tive portion, in the inductive portion of which an intlow of' water is induced througha suction way, and the entry of a freshcharge et' mixture is induced through an admission port, and in the reactionary stroke following the propulsive stroke the waste products of combustion are caused to. be discharged and the fresh charge, if required, to be compressed prior to its igni-- tion for a continuance oit the cycle of action. One method otcarrying this cycle of action into practice, is to make provision whereby, in the inductive portion of the propulsive stroke, a fresh charge of mixture is caused to be vinduced and admitted into an area of the pump disposed above an exhaust below which the products of the ignited charge are swept, the exhaust. being furnished with closure means adapted to maintain it in a closed condition against the entry of air vhile the`pressnre in the pump during the propulsive stroke is above or below the external or atmospheric pressure, and in the reactionary stroke to permit the tree escape otl the waste products through the exhaust until the closure means are acted upon by the impact o't' the returning water, the exhaust being maintained closed during the completion ofthe reactionary stroke, which, it required, may be utilized to compress the charge contained within the area disposed above the exhaust.
v.\n'exainple ot construction according to this invention will now be described with reI-erenee to the accompanying drawing which shows a pump in vertical section.
ln the torni ot construction illustrated a pump cylinder A is provided having an Specification 'of Letters Patent.
Patented June 11, 1912.
open base formed with a toot extension B and having a covering head formed with an admission port C. At a position at a d'istance from the head of the cylinder and from 'the base thereof an exhaust is provided, consisting of a series of, say, four exhaust ports D, two ot which are only seen in the section. The admission port C is furnished with a vvalve E tending to close against internal pressure and free to open under the influence of suction of any required degree. Each exhaust port D is titted with an upper valve I)1 and a lower valve D2 adapted to assume seated positions, one which excludes escape when the internal pressure rises materially above the external or atmospheric pressure, and the other which excludes entry under external pressure while permitting escape under internal pressure above but approximating to the external or atmospheric.
The foot extension B consists of a tubular member carried' upward to present a. column of water, and a water suction way Fis arranged as a branch to the toot extension B, disposed beyond t-lie region ,to which the base of the column of water is projected at the end of the propulsive stroke, and this branch, constituting the sui-tion way F, may be set so as to approximate in direction to the direction ot the Jfoot extension B. To cheek any return low the water suction way F may he furnished with .appropriate means, for example, as' shown by being titted with a non-retiirn valve G5; lgnition ot the charges may be ettected by means controlled by the variations ot pressure generated in the puinp, a niqtthod which has previously been proposed ,ttor tcontri'illii'ig ignition in internal combutstion pumps, for example, as indicated in the drawing, a curved, or other suitably t'ormod, tube ll is provided at the head ot' the cylinder, and adapted to be temporarily deformed,P by the internal pressure produced on the i'iaictionaiy stroke so as to cause a movement to be imparted to its 't'reef end and move a contact arm H1 adapted to establish an electrical circuit comprising an ignition plug l( fitted in commnnication with the head o't the cylinder.
inthe act-ion ot' a pump ot' the toregoing` construction, the initial portion ot' the propiilsive stroke is made under the intluence of the pressure generated by the ignited` charge, and in the inductive portion thereof, which is produced by the momentum whicn the water acquires in conjunction with the reduction of pressure due to the contraction of the products of combustion on cooling, a new charge of mixture is induced to enter the head of the cylinder A and an iniiow of water is drawn in through the water suction way F, and as the propulsive stroke changes from its pressure to its inductive condition, when the internal pressure approximates to atmospheric, the lower valves D2 of the exhaust ports D automatically drop while the upper valves D1 are seated to prevent the entry of air. In the initial portion of the reactionary stroke, the upper valves D1 of the exhaust ports l) offer little resistance to the expulsion of the waste products of combustion, and this condition is maintained 'until the returning water reaches the haust when it closes the ports by impact with the lower valves D2, after which the further ret-- rn of the water past the exhaust ports D acts to compress t-he fresh charge entrapped in the head of the cylinder preliminary to ignition, which is automatically etlected by the rise of pressure produced.
