.1.0- present invention has-in View are: To provide a double oscillating piston arranged to produce a continuous reciprocating ofa pitiuanand a rocking shaft cmmccted therewith; to provide a' plurality oit explosion chaml'bers each operable from both ends-thereof;

to provide a multiple reciprocating motor of the explosive type radially disposed about a. rotary driving shaft having a` [ly wheel and designed to conform to the size of said 20.ly wheel; to provide a plurality ot' hollow sector-shaped explosion chambers radially disposed about a driving shaft providedrl with a ily wheel, said sectors being separated to provide holding spaces tor the valve '25 monntings and operating mechanism therefor; and to provide a multiple unit explosion motor radially disposed about the driving shaft of the engine and having oscillated pistons' rotatably mounted upon said driving` shaft and a translating mechanism for converting the reciprocated motion ot' the pistons to a rotary motion of t-he shaft.

One embodiment of the present invention is disclosed in the structure illustrated in y the accompanyino` drawings, in which like characters of reterence denote corresponding parts in all the views, and in which- -Figure 1 is a plan View partly in section,

ofen exigirle constructed Iand arranged in 4e accordance with the present invention, the

section being taken on the line 1--1 in Fig. `2y Fig. 2 is aside elevation, partly in section, of the same, the section being taken 'on the ,line 2-2 in liig. 1; Fig. 3 is a vertical secil tion of the oscillating pistons employed in the present construction, the section being taken on the line 3--3 in Fig. 4; Fig. 4 is a detail View in side elevation, showing the oscillating piston and the hub thereof; and

"l5/01mg. 5 is a sectional view taken on the line Fig.` 2, showing the face plate and i' in port passages of 'the valve chests. Y. In the=gconstruct1on of every engine eertain 'features are necessary to the ellicency and operation ot the saine. One of these features may beistatcd as beingthe fiy wheel with which the engine is provided. To confine the cubic space occupied by the engine, the shape and size of the fly wheel should be taken into account.

ln the present invention l have constructed and disposed the engine parts as nearly as possible within the area oi' the fly wheel ot the engine. ln doing this .l have attained the most compact 'forni for the engine without limiting the piston area. To do this li have 'formed olipositely extended sectors t'. 'The sectors G, (3 are provided vwith hollow chambers 7. T openingr toward the center to surround the hub of oscillating piston heads S, 8. The sectors (l. (l are constructed in two sections, the upper and lower, beingl parted on a horizontal central line t), the lower section forming and being cast with the hed 10. Disposed about the periphery and side walls of thc sectors 6, G to surround the chambers 7, 7 are water circulatingl spaces 11, 11. The upper and lower sectors are bolted together by bolts 12,' l2 in the usual manner. The chambers 7, 7 are radiated from the center of the hub 123 of the piston heads, S; 8. the said hub being held in separated and bearing relation' by curved walls 14, '14 of the meeting` portions ot' the said sectors.v The piston heads 8, 8 are :formed as shown in Figs. 3 and'lt o'f the drawings, having heads 15, 15 formed to the circumferential shape of the chambers 7 7. Between the heads 15, 15 and thc hub 3 are extended Vsolid walls 1G, 16 constituting thel pistons in the present invention. The walls 16.y 16 are provided with lateral edge flanges 17, 17 radially disposed, as shownin Fig. 3 of the drawings, whereby the edges ol" thel said flanges may rest against the ends ol the chambers 7, 7 to form a pocket between the walls 16, the said Ilanges and the ends ot' the said chambers, as shown in Fig. 2 of the drawings.

As will be hereinafter set forth, the pis- . tons 8, 8 are oscillated about the drivin r shaft of the engine, while the driving shat 1s continuously `rotated 1n a constantv direction. The hub 13 of the pistons 1s enlarged lto provide water circulating spaces 19, 19,

ing spaces 11, 11, protecting a hollow sleeve 20 and the bearing 21 therefor. The bearing -21 is fitted snugly over the shaft 18 to run truly thereon. At the outer extremity of the elongated end of the sleeve 20 the said sleeve is provided with a key 22 to hold in fixed relation a crank arm 23, as shown in Figs. 1 and 2 of the drawings. The crank arm 23 is pivotally secured by means of a pin 24 to a crank rod 25. The crank rod 25 is pivotally secured by means of a pin 26 to a crank arm 27, ixedly mounted upon a shaft 28. The shaft 28 .is suitably mounted in bearing boxes 29, 29 formed at the head of standards 30, 30, which are properly secured in fixed relation upon the bed 10.

' The shaft 28 is provided at the extremity opposite Vthat whereon is mounted the crank arm 27 with a crank arm 31. The crank arm 31 is connected by means of a pin 32,

a pitman 33 and a pin 34 to-a disk 35. The

radial dispositions of the pins 32 and 34 are so'proportio'ned that the arc of the movement of the pin 32 on the crank arm 31 equals in length the path of halt of the outer circular path of the pin 34, or, stated in other words, the rock of the crank arm A31 in each direction producesa complete half revolution of the disk The disk 35 is ixedly secured by means of a key 36 upon the shaft 18.` By means of a key 37, a fly wheel 38 is iixedly attached to the said shaft 18 at the end thereof opposite that carrying the disk 35. it will now be seen thatas the pistons 8, 8 are rocked about the shaft 18, the said shaft 18 and fly wheel 38 connected therewith, are vdriven in a con; tinuous and contant rotary direction by reason oit' the translating mechanism con-l sisting of the crank arm 23, crank rod 25, crank arm 27, shaft 98, crank arm 3 1, pit- I man 33 and disk35 interposed between and connecting the said pistons and said shaft.

The pistons 8, 8 are oscillated by explof sions of an explosive mixture admitted and conned under proper conditions within the chambers 7, 7 and upon opposite sides of the' walls 16, 161 of the said pistons. The explosive mixture is the usual mixture ot' gas and air, and is admitted to intake chambers 39, 39 of each of the valve casings 40, 40. A'The casings 40, 40 are each provided with an` intake chamber 39 and an exhaust chamber 41. The said chambers are divided by a wall 42, andare each connected through ports formed in a wall 43 with a passage 44 formed in open communication with the interior of the chambers 7. Each, of the ports in the wall 43 is closed b a Vvalve 45, having a valve stem 46 extende Vthrough the outer wall of the casing 40 and provided with a washer 47 adjustably mounted thereon by a set nut 48. The stems 46 are cach provided with a head 49, whereby the various valves may be depressed to remove the said Valves from the seat against the expansion of a vspring 50 surrounding each of the said stems 46.

The casings 40, 40 are each similar, and are mounted upon the sectors 6,16 by being bolted to the ends thereof by means of bolts 51, 5l. By means of this arrangement the casings are disposed on opposite sides of the pistons 8, 8, thereby being adapted to cause an explosion on each side of the said pistons within the chambers 7, 7, and to scavenge on each side or the said pistons. Admission o'f the explosive mixture and the exhaust ofthe products of combustion are controlled by the valves 45,l controlling the passage into and out of the chambers 39, 39

' and 41, 41 respectively. It will be vunderstood that the valves 45 will be constructed to dimensions suitable for the employment in their respective operations.

It will be noticedthat the disposition' of the casings 40, 40 is such that they are not extended beyond the circumferentialr line of the cylindrical shape of the sectors 6,6. The operating mechanism for the valves is likewise disposed within the space between the sectors and within the projected circumferential line thereof. The engines of which the pistons 8 and chambers 7 constitute the principal elements are of the four cycle type,

therefore gear wheels 52, 52 are suitabl proportioned. to a gear wheel 53 in suci 1 manner as to' operate the Valves constantly with the known action lof engines of this type, and with regard to the alternate action and opposite vdisposition of the valves with relation to the chambers 7.

A Vshaft 54 is provided wi' 56. 'The cams 55, as shown in Fig. 1 of the drawings, are disposed in the pathot rollers- 57 mounted on the ends of lifting Apins 58.

th cams 55 and.

The pins 58 are guidably mounted in '.braclr- (it-s55), 59, and the upper ends extend under the tail 60 of a rockingdlever 61, the spatula end 62 whereof rests upon the hea'd49` of the valve stem 46. The connecting mecha nism for operating thevalves is duplicated for the cams 56, which as shown in Fig-2 of the drawings, rotates in the path of' wheels 63 mounted on the ends of`pins 64,

for controlling the operation of the intake valves for the chambers 7. The cams 455 and 56 are disposed in proper timed relation. The said cams are oppositely disposed on the shaft 54' mounted on oppositel sides' of the engine, whereby the valves are mutually synchronized W1th reference to each iris other and with reference tothe double acl tion of the pistons 8, 8 in the'chambers 7,

Mounted upon the shafts 54 are suitable iesvr rotary electric igniters 65, 65. -The station` ary outer casing is provided with suitable terminals 66, 66 properly disposed with reference tothe coil and spark plugs 67, 67. The casings are connected by a rod 68, by

p moving which the spar-kers may he adbeen voided from the lower chamber vaneed or receded with reference to the coinpression oi the pistons 8, S. The chambers 3S), 39 are provided with inlet and exhaust pipes ('39 und 70, as shown in Figs. 1 and Assuming that the pistons 8, 8 are disf posed as shown in Fig. 2 of the drawings7 and that the explosive .mixture is compressed to lthe right ot' the up )er extension of the piston 8 in the upper cliamher 7, the operation is as follows: The spark being produced in the plug 67 at the right of the upper chamber 7, explosion occurs in the said chamber to the right ot' the said upper extension-of the piston S, driving the said upper extension ot' the piston to the lett. By

the same movement which previously disposed the upper extension ot the pistou 8 at. the right ot the uppei` chamber 7, the lower extension ot' the piston 8 has been moved to the le't't ot the" lower chamber 7. in the action 'of the lower extension ot the piston 8 there has heen drawn into the lower chamber 7 a fresh charge ot' the explosive mixture, to the right of the lower cxtensicu ol the piston 8. Simultaneously there has 7 thc dead charge of a previous explosion. lii'hen now the explosion just above described occurs in the upper chamber 7. the dead charge of a previous explosion in the said upper chamber 7 is voided through the exhaust port. to to the leli oi the said upper 7 .siiniultaiieousl)7 with this movechaniber i. nient, the piston 8 in the lower chamber 7 carried to the right, compressing the charge ol? t'resh explosive mixture at the right ot' the said lower chamber 7. When the said lower extension oli Athe pistou 8 has been thus moved to thev right. a fresh charge of explosive mixture has been drawn into the said lower chamber 7 to the left ot' lthe piston 8 therein. At this instant, the .eligine is in the position where a compressed charge of explosive mixture is held to thc "right of the lower extension ot-tlie piston 8 inthe lower ehaniber 7 a loose fresh charge ot' explosive mixture held to the left oi" the lower extension ot the piston t in the saine lower chamber 7; and in the upper chamber 7 to the right ot the upper extension of the pistou is a dead or rouihusted charge of explosive i'nixture. 'llie ports iti the lower eliainner 7 on both sides o'l' the saidy lower chamber are closed. .l`he iii'inlce port to the lett of the upper extension ol the piston S in the upper chamber 7 has inst heen, or is ou the point` ol". oiiciiingr. 'l'he exhaust porti on the right olT the upper chamber 7 luis opened, or is ou the point ot' opening. The secondv explosion ol the .si-ries being desrrilafd noivfot-miracaused b v a spark in the plug; (i7 at the rip-ht oi the lower chamber 7.' This scf'oni'l explosion moves the lower extension ot the piston. S to the left of the lower chamber 7, compressing the explosive mixture therein and to the lei't of the said piston 8. In the upper chamber 7 the upper extension of the piston i. is' moved to the right, forcingr through the intake valve to the left of the upper chamber 7 a fresh charge ot explosive mixture. -\t this instant the engine is in position where, in the loiver chainlurr. to the right oithe pistonti, the said chamber is lilled with a dcadcharge; to the left in the said chamber is a compre-sed charge ready ior explosion; in the upper chainher. to the lett of the piston H. is a loose 'fresh chai-gre ot' ex- ,plosivi` mixture; while to the right the old charge has been completel)r voided. At this moment a spark is caused in the lower chamber 7 to the lett of the piston S, moving?y the same to the right of the chamber,

the exhaust port to the right of the said chalutier being open to permit the scavenging otlthe dead charge of combustcd material. l`heuppcr extension of the piston 8 has been ii'iovcd to the lei't, compressing in the lelt ot tle upper chamber 7 the explosive mixture, while to the right ot' the said upper chamber and extension'of the piston 8 therein has been drawn a fresh charge oi explosive mixture. At this moment.7 after the three explosions, the'engine is in the condition where.; in the lower Chamber on the right of the pstonS, the-dead charge has been voided to the left of 'the piston 8, and filling the major portion of the said lower chamber 7, is the coinbiisted or dead charue of the Ilormer explosion; in the upper Chaniber 7 is held under compression a fresh chin-tre 7: while at the right of the piston 8 in' the said upper chamber 7 is drawn a loose fresh charge ot' explosive mixture. At thisl inoiiient the fourth explosion is produced by causing a spark in the plug 6T to the'left of the upper chamber 7. With this explosion the c vclc is completed and the parts are returned to the position above set. forth at the commeneeiueut oi this description. It will 'fue observed that' the explosions have been surcos-ive. and pri'igi'essively arranged, and in the direction opposite to that: followed by the ivhccl 25S and sha lt connected therewith. liv means ol' this arrangei'nent, the cams and .1(3 are rotativcly actuated over an are ot' 270', the proper disposition for the cams 'for operatingr the intake and exhaust valves in engines of the four-cycle type.- As a result ot' the action above described it will he utiliz-ed that at each quarter oi the rot'ation ol the shaft 18 a forward impulse is imparted b v one ot the four explosions trauspiringr in the tivo chambers 7.

lt will he, observed that within a confined space there has been produced an engine, the piston area ivliereot' is exceedingly large and the power production exceedingly great.

at the left of the said upper chamber 3'0 and said radially extended arm; means for It will also be observed that the power impulse imparted vto the shaft is even and oonstant, thereby equalizing and nullifying the vibration du tothe direct reeiproeation of 5.a double impulse engine,

Having thus described my invention, what I claim as new and desire to secure by Let-. ters Patentisz-- An explosive engine, comprising a driv ing shaft provided with a .crank arm; two hollow sector-shaped vexplosion chambers disposed radially about said driving shaft and extended =in opposite directions therefrom having straight radially disposed ends; walls separated to form recesses for valves and mechanism for controlling said valves; two oppositely extended piston blades integrally Connected to form a central hub bearing rotatively mounted on said 0 shaft, said piston blades being operatively extended in said explosion chambers and said blades having extended bearing ends disposed in guided relation with the cylindrical walls :vf said chambers; a radially extended arm lixedly connected with said pistons beyond the confines of said chambers; a crank arm lixedly mounted on said driving shaft; plurality of pivotally /united pitmen connecting said crank' arm guiding the united ends' of said pitmen in a straight path a plurality of valve meehanisms disposed on each of the said end walls of said chambers and having passages through said walls to within said chambers; a plurality of -eam shafts mounted in bear ings supported on said radial walls, said shafts being extended in parallel relation to the driving shaft; a plurality of cams mounted on said shaft-s and arranged in quadratedrelation, said cams adapted to operate the similar valves in the adjacent valve operating mechanism at intervals of a quarter turn of said shafts; anignition system embodying four igniters, two of which are mounted in each of said explosion chambers and one of which is disposed adjacent to each of the radial sides'in said chambers; and a timing mechanism for operating the said igniters in rotative succession and in a rotary direction the reverse of that imparted to the driving shaft. I

In testimony whereof I have signed this specification in the presence of two sul seribing witnesses.
