MULTIPLE-@YLINDER EXPLOSIVE-ENGIN E.
Specification of Letters Patent.
Patented July as, rare.
Application filed April 9.1, 1911. Serial No. 622,525.
To all who???) it may concern:
lie it known that I, Evnnn'rr S. CAMERON,
a citizen of the United States, residing at continuous valve structure to control the in-- let and exhaust of a plurality of cylinders and another similarly-arranged valve structune-to control the exhaust. of a like number of cylinders, and a special gearing arrangement to drive both valve structures in one direction.
The objects in view are to provide an engine of this class withsimple and inexpensive means for governing and regulating the admission of carbureted air into two, four, or more cylinders, and the exhaust thereof, and having the advantage of being formed to facilitate machining, assembling, and interchangeability of the parts. I attain these objects by the construction illustrated in the accompanying drawings, in which Figure 1 is a side view of an explosive engine partly in section and partly in elevation,.showing the manner of mounting my improved intake valve structure, and the gearing arrangement therefor. Figs. 2 and 3 are side views of my improved valve structure; Fig. 2 belng the valve member de-- signed to be actuated b the gearing arrangementto control the intake and exhaust of one cylinder, and Fig. 3 the valve member for connection with the aforesaid memher to control the intake and exhaust of the next adjacent cylinder. Fig. 4 is a cross-section-taken on line of Figs. 1 and 5, showing. the means for respectively locking each pair of valves. 5 is ahorizontal sectional view taken on line y.-y. of Fig. 1,
showing my improved exhaust valve structure. v
Like reference characters indicate like parts. Y a
My invent-ion is essentially designed for use on the multiple cylinder type of eXplo-- sive engines, and in the drawings I illustrate two such cyllnders a, a, vertically-arranged upon the usual crank-case b, and each cylinder is provided at its upper part with a central horizontallyarranged integral tubular chamber a which communicates with the usual inlet and exhaust parts (not shown) at its upper portion, and a port a at its lower portion, the bore of each chamber a forming a bearing surface for my improved rotary valve structure, presently described. On one side of each cylinder a, about midway its height, is also arranged a horizontal integral tubudar chamber a whose bore forms a bearing surface for my improved rotary exhaust valve structure, and said chamber a communicates with discharge openings c, a, in the manner shown drical body portion 0 of ,a length nearly equal to that of the valve chamber a and this body portion'is provided with a central transverse opening therethrough to form a port a. Said member 0 is provided. with a concentrically reduced portion at each end, one forming a screwthrea ded stem c and the other a connecting portion 0 which is slotted as shown at 0 The member 0 is constructed the same as the member 0 above described, exceptin instead of having a stem 0 at one end both ends are similarly formed with slotted reduced portions -o.
Referring to Fig. 1, wherein is shown the manner of mounting the valve members '0 v and 0 the stem or of the former member passes through a support cl which is secured upon the faceofthe valve-chamber a, and
on thethre'aded portion of said stem is a nut d which impinges again'stthe side of a spiral gear d to hold the latter fast upon said stem. The body portions of each valve member 0 and c fit within the valve chambers a and the end portions abut each other and are connected together by a fiat plate or key 6, which is inserted through the slotted openings 0 c and thereby lockssaid valve members together. The inner connecting portions 0 of the valve members 'c. and 0 are inclosed by a bushing f whose ice ends are secured upon the adjacent faces of;
the valve chambered and the outer disconnected portion a? of the'va'lve member '0 is inclosed by a cap 9 which is secured upon the face of the valve chamber.- The bushing f is designed to prevent displacement of the key or plate c from the valve portions c Said bushings f also fit the reduced end haust from both of said'cylinders, through V the chambers a a and'this construction 'and arrangement of parts are' exactly the same as the valve structure above described, except that the diametrical size-of these exhaust valve members and-their bearings are proportioned relatively smaller, to suit the working condition of the engine.
. valvesareeachprovided with suitable packing-rings, as it, h in Figs. 1 and 5, and said valves rotate at one'quarter the speed of the crank-shaft z, and each valve is so positioned that its port 0 stands at an angle of one eighth around from the position of the portof the next following .valve.
By having a series of interchangeable valves to control the inlet and exhaust of ,two, four, six, or eight cylinders, with means for. connecting their ends together, as described, aifo-rdsa flexible joint to allow of expansion and contraction of said valves at points-between each cylinder-casting.
The gearing arrangement to revolve each series of valves consists of an upright shaft j which. is mounted in bearings of the supportsd, d'and'on said shaft is made fast spiral gears-d which mesh with spiral gears d, to drive each series of valves and with a gear (i secured on' the end of the-crankshafti to'drive said shaft- 7'. By use 'of The spiral gears, as described, a silent drive obtainechfor thevalvesl The usual mag neto (not, shown) is also actuated from the shaft j, by means of a gear on said shaft (not shown), which meshes with the gear Z on the magneto shaft m. Said shaft j also operates the oil pump n, which is fitted on the lower end portion of said shaft and contained in the forward part of the oil tank 6 in order that any leak or overflow from said pump may be returned directly to said tank. The supports for the upright shaft I i have each a cover to inclo-se each engaging" pair of spiral gears, as at 0 and p in Fig. l. I a
Having now described my improvements, what I claim and desire to secure by Letters-Patent, is y In an explosive engine having separate chambers, cylindrical valves to govern the intake and exhaust through saidchambers,
said valves having slotted reduced end por tions extending from each of the valve chambers, a key to fitwithin the. slots of each adjacent valve, a'bushing fitting and surrounding the slotted redt w end portions andsover the keys and secured to the' adjacentfaces of said valve chambers, whereby said valves are positioned-centrally in said chambers and end thrusts prevented upon adjacent valves, and meansto rotate said valves.
