Specification of Letters Patent.

Application filed May 16, 1912. Serial No. 697,592.

and State of Michigan, have invented certain new and useful Improvements in EX- plosive-Engines, of'which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an nternal combustlon engine and to a certalnarran 'ement of the parts thereof whereby great etiiciency is obtained, there being means provided for varying the mixture ofthefuelto'suit'different requirements of serviceand other details of construction being includedwhich increase-the effectiveness of the motor. E

the shaft 12 and a sim1lar.- pair-2l' connected The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in side elevation of a preferred form of motorthat embodies features of the invention; Fig. 2, is a view in horizontal. longitudinal section taken on or aboutline Ha ll of 1; Fig.3 is avieW in cross sectiontsken on or about line TIL-11]: of'Fig. 2; 4 isa view in section taken on or about line IV-IV ofFig. 3; and Fig. 5 is a view pan tially in section and partially in elevation taken on the opposite side of the motor from the point ofview of Fig. 1.

In general terms, the motor consists of two sets of oppositely revoluble blades trav-. ersing segmental chambers in which explosionand expansion of the fuel takes place, such se mental chambers being arranged in pairs and interconnected by abase chamber and the blades of each set being mounted on a common .shaft. The two shafts of the sets are interconnected to turn in unison and operate an air compressor and fuel feeding device through suitable con necting mechanism, the fuel feed mechanism including means for varying the amount of the feed.

Referring to the dravvingsa substantially rectangular casing 1 has internal upright partitions or cross WZLllSQ. depending from the top of the casing to a guide-w'ayfi' on the side Walls in which base plates a1 reciprocal-ted longitudinally of the pasing a; by intermeshing. rack bars 5 and segmental gears-6. The latter which are secured on suitable shafts 7,-are severally operated by intermeshing segment pinions indicated at 8, one of which is carried by an oscillatory arm 9 to which motionisimparted by the cam track 10 of a cam 11. These cams are mounted on a shaft 12 journaled longitudinally of the casing to Which one set of blades 13 are secured on the end of arms 1 14 to "traverse segmental chambers 15 formed of Patentecl'Jan. '7,

appropriate design and material on the ex terior of the. casing. A similar, set of cha1nhere 16 disposed symmetrically with the chambers 15- are likewise traversed by. asec ond set of blades 17 connected byjarmsliij,

to a companion. shaft 19 parallel to the shaft :12. A pair of chambers of each set open.

into the compartment of the casing formed betWeen' the adjacent cross Wallsthereo'f.

A pair of beveled ears 2Q connected to of the main casing. TheportsZ-ll are con- :trolled by suitably disposedreciprocating slide valves 38 or the like which are operated from the shaft- 12 and-cams 11 by rock arms {island roclsshafts 35 that carry segmental gears 36 each in mesh ,Withe rack 37 on'the valves 33.

Fuel supply from" a suitable source through a pipe'38 is injected-into the air.

supply for each of tmfchambers by pumps having barrels 39 preferably disposed in :pairs with pistons 40 interconnected Withstems 41. Each stem is reciprocated by a rock arm 42 Whose free end is provided with a cam roll 43 travelin in the path of a cam 44: driven by the she 't 19. The other end portion of the'arm is longitudinally slotted and engages a stud 4:5 on a lever 46 that terminates in arack bar 47 fulcrumed against a pinion 48 with which it meshes by means of a hand yoke 49. An intermedi- :'ate slotted portion 50 of the arm engages a transverse pin 51 on the piston stem 41 to oscillate the latten and the'stroke may be lengthened or shortened by moving the stud into or from the end] ofthe rack arm 42, as

loo

by means of a hand wheel 53 for turning the gear 18. To insure uniformity of action of the pumps the various rock arms are interconnected for adjustment as by chain and sprocket connections shown at 52.

The parts are so disposed and arranged in timed relationthat when the base wall 4: closes a compartment in the main casing 1, the companion blades 13 and 17 are substantially in the position shown in Fig. 3 with the air and fuel lin compression between them ready for explosion. As a result of the explosion the blades are forced apart.

around the segmental chambers and a clear passage is afforded for them by the throwing of the base 4 over the companion compertinent as the blades approach the lower portion of the casing chamber. The several sets of blades are so timed and disposed in relation to each other that one base-slide operates for two adjacent chambers, while the fuel and air pumps are likewise arranged to furnish the proper fuel and compression at the times needed.

One feature of' the construction is the mechanism which allows the variationof the fuel supply to meet different requirements ofservice without changing the air compression which is uniform. under all conditions. By a proper disposition of the parts a substantially uniform torque is conveyed to the shafts and a motor thereby obtained which is substantiallythe equivalent of an eight-cylinder motor of the conventional type but which is more compact. and of less weight per horsepower unit. As indicated the walls of the explosion chamber may be internally jacketed with fire proof material and other provision may be'made for preventing deterioration of the parts from excessive heat. It is "to be understood that the usual provision is made for lubrication and other details of mechanical construction, not shown herein, are carried out in conformity with good shop practice. w p 4 Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself, to any particulan form or arrangementjof parts.
