To l-221.com may concern:
lie it known that I JOHN F. Deer, a. citizen of the United States, residing at Boston, in county of Suffolk and State of Massachusetts, hsve invented new and useful Improvements in Rotary Explosive-Engines, of which the following is a. specification.
This invention has relation particularly internal combustion engines, the four stroke cycle type including s rotor leaving a group of cylinders, arranged with their axes substantially parallel the rotor and provided with pistons which are operated to drive a shaft at on angle to the axis or the rotor.
The principal objects of the invention are to attain, simplicity of construction and elliciency of action of engines of this class, and especially to sttsin freedom from noise and vihretion such as is ordinarily caused by reciprocating pistons and connecting-rods.
More specifically, it is snoliject of the inven.-
tion to provide :1. multiple cylinder engine capable of transmitting rotary motion to e driven shalt Without the employment of cronies or Cit-i118. A further object is to simplify end irnyrovc the valve construction of rotary engines.
To this end, on engine embodying my im. proved engine comprises t-rotor connected to drive end in unison with e. driven shaft, but on on which is at an angle to the sl'iecft, and is provided with cylinders,'the pistons of which are driven shaft in such manner that the explosion in the cylinders will transmit rotary motion to the driven shaft Without reciprocation of the pistons relatively to the said shaft end it rotor-supporting shaft coaxial with the rotor. Said supporting shaft is geared to tlierotor to rotate in timed relato the letter, and is vide it supply conduit for the explosive mi ture, an exhaust conduit for the products of combustion, a supply or intake port through which the explosive mixture is permitted to pass to the cylinders, and an er:- hcust port through which the products of combustion are permitted to pass from the cylinders to the exhaust conduit. The said shaft, therefore, valves and is hereinafter valve shaft.
The invention. further consists in such novel features of construction and cornhinations of ports as will hereinafter be more fully described and pointed out in the claims.

Fig. ft'is a section on the line 2-42 of Fig. 1.

Figs. 5, 6, 7', and 8 are transverse sections 3 is c section on the line 33 of through the rotary valve showing the inlet and exhaust ports at the beginningof reach of the four piston strokes of e three-cylrnder engine.
Figs. 9,10, 11 and 1?: are similar views, showing a modified arrangement oi the ports.
As illustrate in the drawings, the engine has chase 10 and uprights 11 and 12, which are provided respectively with hearings 18 and 14, one inclined relatively to the other. J'ournaled in the bearing 13 is the driven shefi carrying a driving head 16 which is preferably a disk. A. rotor 1? is mounted. to rotate uponcne end portion of c rotary shaft l8,wliich,l call the valve shaft for the reason hereinbefore stated, the other end of said valve shaft being ourneled in the hem ing 14 and held therein between an annular flange 19 and a collar 20 and nut 21.
A nuiversal joint 22 lIlCllldlIlg a member 2% attached to and coaxial With the rotor ii, and a member 22 coaxial with the shaft 15; connects the rotor with the shaft, so that the Weight of the rotor is distributed between the bearings 13 and i4, and so that said rotor and said driven shaftnre caused to rotetem unison. The rotor 17' is provided with cyl inders 23, each cylinder havinge. piston 52% connected through wrist-@1125, connecting rod 2 6. and .a universal joint including mean hers 27 and 28,3vith the marginal posdaion of the head 16, points spaced from the axis of the driven she-ft. 4
The valve shaft 18 is providedwith an inlet channel or conduit 30 which surrounds a central exhaust channel or conduit 31 and is provided with an inlet port 32, which rcceives the explosive mixture from an annular. chamber 35 connected with the supply pipe 34, and with a supply port 32 which delivers the explosive mixture successively in radial passages 36 in the rotor communion-tins jvvitit The engine may be designed with the cylinders 23. The exhaust conduit 31 is provided with an exhaust port 33, which also communicatw successively with the passages 36. The explosive'mixture thus admitted is compressed. in the cylinders and ignited in the usual manner, and the products of combustion are then exhausted through thepawages 36, the exhaust port 83, and exhaust conduit 31. i
On the rotor 17 is a hub 40, surrounding the central valve shaft 18. A gear ll fixed to said huh, drives a gear 42 which'is fixed to the valve shaft 18 through the interniediatepinions 43 and 4a, which are mounted upon the stud 45, said gearing being in the ratio of three to two, so that the valve shaft 18 will make three revolutions to every two revolutions of the rotor. This will cause the intake and exhaust to occur at the proper intervals, as illustrated by Figs. 5, 6, 7, and 8, Which show the relative positions of the intake and exhaust ports of the shaft 18 and the radial passages 36 leading to the cylinders, for each of the four strokes of the pistons. The cylinders are conventionally indicated by the Roman numerals I, II and III. A
double intake and exhaust ports, instead of the single ports already described, in which case the central shaft 18 and the rotor will be geared together in the ratio of one and one half to two, said shaft making one and one-half rotations to every two rotations of the rotor. Figs. 9, l0, l1 and 1? illustrate this embodiment of the invention and show the relative positions of the supply and exhaust ports of the central shaft and the passages leading to the cylinders in the rotor.
Obviously the invention is adapted to be embodied in engines having various multiples of cylinders, for example, by gearing the central shaft to the rotor so that the former will make two and one-half rota tions to every two of the latter, the engine may be constructed with live cylinders.
The spark plugs 46 may be ignited by any desired means. I prefer, however. to employ the jumospark system and have shown a 'primary circuit, one terminal of which is suitably grounded on the framework of the engine, the other terminal. being a stationary contact 47, (Figs. 1 and 4-). A retating contact maker 48 on the shaft 18 intermittently closes this circuit. The secondary circuit of this system also has one terminal grounded on thefraine worl of the engine, While the otheris led by a contact finger 41%; to a conducting ring 50 which encircles the hub 40 of the rotor. The ring includes an annular body 50 of insulating material and three contact blocks 51. insulated from each other and from the rotor by said body and connected. in any suitable manneiya-s by the contact fingers 52 with the spark-plug 46.. The stationary contact 4? of the primary circuit is fixed to a ring 53, loosely mounted uponen anuuiar flange 37 integral with the hearing it, and
is maintained in fixed radial relation Wit said contact maker 48 by means of a spring;
'5 which is carried on the engine frame and tact, thereby advancing or retarding the spark in the cylinders.
The reciprocation of the pistons in the cylinders causes the pistons to act on the head to rotate the latter and the driven shait 15 in a Well known manner.
It Will be seen that an engine designed to embody the essential features of this inven tion, as hereinbefore set forth, will possess many advantages, among; which may be mentioned noiselessness in operation and freedom from vibration. This is due to the fact that While there is relative movement between the pistons and the cylinders, there is no reciprocation. of the pistons with re spect to the driven shaft 15. The engine may he adapted to'he cooled by any suitable cool- 'ing system.
' Various changes in the form, proportions, and minor details of the invention he resorted to without departing from the spirit and scope thereof, and I consider nig self entitled to all such variations as may be within the terms of my claims.
