3 Claims.
The present invention relates broadly to motive devices and more particularly to a combination constituting an improved motive system of the lluid pressure type adapted to be elective under predetermined conditions to deliver fluid pressure in such amount as to produce actuation of the motive device.
In combination with the motive device (motor) there is provided means for producing operating pressure for the motor. This means consists of a combustible solid fuel, preferably containing sufcient oxygen to support its own combustion, the combustible solid fuel being responsible for the generation of gases under the heat derived from the combustion of said fuel.
Gases of the general character generated by such fuel are known to have light density, and in order to maintain their expansion and pressure efficiency it is desirable to subject them to direct contact with the llames issuing from the burning fuel. In this manner such gases may be said to be superheated, and such superheated gases are desirable in the operation of a system of this character, for gases generated at a point remote to the part to be moved and transferred without superheating to a point adjacent the part to be moved, if they produced pressure sufficient to move the said part, would further cool under the expansion permitted by the moving part, and thereby cause the pressure to fall olT appreciably.
As a result of such pressure drop, it occasionally happens that a part of the solid fuel' is not fully consumed, and the unconsumed residual may remain as a gritty deposit (chiefly carbon), upon the part to be moved, or sections of its housing and associated apparatus Objects of this invention include the provision of a method and means of dislodging such carbon deposits, so that they may be blown out of the device during the gas exhaust stage of the operation, or-if not actually dislodged-at leastsoftened to a degree that willV prevent interference with the proper functioning of the movable -parts of the motive system,
Another object is to provid a method and means of introducing, into said housing and associated apparatus, a measured quantity of a grit dislodging substance, and of propelling said sub- (-Cl. (S0-M) breech mechanism to condition it for introduction of said grit dislodging substance.
In practicing the invention I employ as the grit dislodging substance, an oily liquid vhaving not only the capacity of softening such gritty de- 5 posits, but also of holding the carbon content thereof in solution or suspension, so that it may more readily be carried oi with the exhaust gases, while at the same time providing a sufficient amount of lubrication of the parts with which it comes in contact.
Other features and objects of the invention will become apparent from inspection of the specification and drawing. It is to be expressly understood, however, that the drawing is for the purpose of illustration only, and is not 'designed as a definition of the limits of the invention, reference being had to the appended claims for this purpose.
In theA drawing,
Fig.'1 is a view, partly in section and partly in elevation, of a motive system including a part to be moved, a breech mechanism, and a connecting conduit, all constructed in accordance with the present invention;
Fig. 2 is a perspective view of one form of screen, or grid, constituting a part of thebreech assembly; and
Fig. 3 is a sectional view along line 3-3 .of Fig. 2. 30
In carrying out the present invention, there may be provided a housing l, of substantially cylindrical shape, having at one end thereof a ange 2 adapted to support the motor in position. Where used as a starting motor for internal combustion engines, this ange will be of such construction as to permit the motor to be bolted or otherwise secured in the desired relationship. to such internal combustion engine by means of bolts 3 extending through suitable openings in the flange 2 and projecting into the crank case It which surrounds and houses the internal combustion engine member` (crankshaft or crankshaft extension) shown at 5.
Formed on the head of the cylinder l is an externally threaded boss 6 adapted to receive one end 'll of the charge burning unit 8, which is preferably threaded thereon, and within the cylinder is a piston 9 adapted to actuate the engine engaging clutch element Il through the instrumentality of motion translating elements such as those indicated in patent of Romeo Nardone, No. 1,951,032.
In the burning unit 8 there is provided a tubular grating or grid l2 adapted to permit' the 55 passage of the generated gases and the ames of combustion into the lower part l of the unit, and thence forward to the piston 9, While preventing the passage into the cylinder of large particles of unburned solid fuel. Upon the accumulation of sufficient pressure Within the housing I, this pressure Will be effective upon the piston 9 for imparting a longitudinal motion thereto.
The` means illustrated in Figure 1 for obtaining the desired operating pressure comprises a firing chamber I3 illustrated as containing a cartridge i4 within which is the usual priming charge and a combustible charge. The ring chamber is also provided with a coverplate I6 effective to maintain the firing pin I 'I in position. Upon actuation of the ring pin, the priming charge will be ignited, thereby serving to propel the combustible charge through the ring chamber I3 and intol dome i8 from which point the burning fuel and resulting gases enter conduit 2|, by way of the ported cage or grid 22, provided in lieu of, or a supplement to the grid l2 above described, and having a similar function, as well as the additional function hereinafter pointed out.
I have illustrated the ring chamber I3 as equipped with a safety 'device in the form of a rupturable diaphragm 23 adapted to be broken in case the pressure conditions Within the system exceed the maximum pressure for which it is designed. fThis rupturable diaphragm 23 may be detachably held in position by a suitable nut 2li, removable and replaceable therewith as may be required.
In addition to serving as a` protection against' excess pressure development, cap assembly 23, 24 permits ready access to the chamber i3 and conduit 2i for insertion of a capsule 26 containing the grit dislodging oil above referred to. VAs shown, this assembly 23, 24 also permits, when removed, manual rotation of the annular cage 22 through an arc of ninety degrees, more orrless, to bring the larger, diametrically opposed, openings 22 and 29 into alignment with the conduit 2i, to permit passage of the capsule 26 therethrough, the normal position of said cage 22 being that in which said openings 28 `and 29 are offset from the conduit opening, so that the conduit opening Will normally receive only such particles of the solid fuel as can find their way through the smaller ports` 3l constituting the grid or screen part of the cage. Such manual rotation of the cage 22 is ofcourse facilitated by reason of the many apertures in the said cage, which apertures readily lend themselves to the use of any suitable tool by which the cage may be turned with respect to the surfaces of the elements I3 and I8 in which it is received-there being no necessity for removal of the member I8 from the member I3 in order to permit this turning of the cage 22 whenever desired.
As shown, cap 24 threads onto a boss 33 which is identical with a second bossV 34 opposite thereto, so that either boss may receive the tube fitting 36 and tube 2 I, while the other remains available for the cap, thus rendering the breech device, as a whole, capable of installation in two different angular relationships with respect to its supporting means 31. Moreover, while it is preferred to insert capsule 26 in the manner recited, so that it will be propelled intact as far as the grid I 2, or nearly thereto, as indicated in dash lines at 4I, prior to consumption of its covering, said capsule, or any equivalent thereof, may also be inserted along with the cartridge II-that is, through the vnormal cartridge openingin which event its inflammable covering (of Celluloid or the like) will be consumed in chamber I3 or I8, and only the oil contained therein will pass through cage 22 into the tube 2|, unit 8 and cylinder I.
What is claimed is:
l. In a closed system for development of fluid pressure by generation of nitrogenous gases from a nitrogenous solid charge, to actuate a part to be moved, means for dislodging carbon deposits therein comprising an inflammable capsule containing a carbon softening oil, and means for inserting said capsule into the space lying between the nitrogenous charge and said part to be moved.
2. In a system for development of pressure by the ignition of an explosive material containing carbon, which material, as it burns, produces pressure to actuate a part to be moved, means for preventing the accumulation of deposits of carbon remaining unburned, said means comprising an inflammable capsule containing4 a carbon softening oil releasable therefrom as ,the enclosing capsule is subjected to the fire of the burning carbon and consumed thereby.
3. In a closed system for development of fluid pressure by generation of nitrogenous gases from a nitrogenous solid charge, to actuate a part to be moved, means for dislodging carbon deposits therein comprising an inammable capsule containing a carbon softening oil, and means for exploding said solid charge and thereby developing iiuid pressure to act upon said capsule to propel it toward said part to be moved.
