Application' mea July 12,1913. seriai mj'z'raesa a connections between the valves and thevalvel .driving shaft. Where tappet rods are used. in combination with a cam shaft it involvesv considerable trouble as it is diiiicult to rerelatlon.
adjust the tappet rods and cams' in properf 205- This invention relates to explosive engines wherein the valve driving mechanism is mounted to form a unit with the cylinders -that is bodily removable from the base without altering the. adjustment of the valve `26 mechanism or inany way disturbing any portions of it except the connection betweeni the mai-n or crank shaft and the cam shaft.
The. invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims. v
In the drawings, Figure 1 is a view, -partially in elevation and partially broken awaylv and in'section, of a motor that embodies fea-- .tures of the invention; and Fig. 2 is a View, apartially in side elevation and partially in section, of an end portion Ao the motor showing one form of connection between the crankA and .cam shafts.
Asherein indicated a base 1 and crank 40,-case 2 house a crank shaft indicated at 3 that is operatively connected in the usual manner tov pistons (not shown) plying. in cylinders 4. The latter are cast en bZOc, or are secured or mounted together so as to constitute a unit. structure that can be taken 4away from the base without difficulty. Each cylinder is provided with a puppet valve closure 5 that is disposed in theusu'al manf ner to seal an annular valve seat 6 formed in a passage way indicated at .7 whlch ex' tends through the' cylinder wall and water `jacketwithiarybutlet through a face 8 mechanism may be housed by a removable against which an intake or exhaust manifold may be clamped. The designand arrangel A ment of the valve closure and seat with the passage which it controls may be as desired as the valve structure itself does not form a part of this invention.' As herein shown' the valve is easily accessible'for inspection or withdrawal through an opening. that is 60 closed by a cap 9. Y
. An elongated bushing 10 or guide sleeve is mounted in the casing of the cylinder in axial alinement with the valve seat 6 `and closure 5. A dependin tubularstem 11 on 65 the `closure is reciproca le longitudinally in the sleeve. A shoe 12 is secured in the lower end portion of the stem 11 in such manner as to be adjustable longitudinally relative to the stem.` This may be conveniently accomplished by the use of a screwthreaded stud y 13 on the' foot engaging similar interior Vthreads in the sleeve. An annularV stop` 14 formed on the foot holds a spring member in compression between it and the wall of the cylinder 'through which the bushing'l() extends, the latter acting as a keeper for the spring. The sto is cut away to form apertures through w ich cotter pins 16 may be inserted to hold the stem and stud 13 in ad- 80 `justed position.l
A valve gear casing 17 that isformed integrally on the cylinders-4 or'is. securedthereto, houses a cam shaft 18 thatis journaled ytherein in suitable relation to the shaft 3.' Cams 19 on theshaft bear against the shoes 12 of the cylinder valves to cscillate the latter and thereby operate the valves in the usualmannen The casing isclosed by a cover plate 20 which is removably se cured as by studs 21 and nuts 22 or the like over the valve stems and their connections to completely house the latter. The opening that is normally sealed by the cover 20, is so disposed that the loner portion of the casing 17 forms an oil well of such depth that the cam shaft'and shoes may be madeto run in oil or other lubricant, at all l times. .The cam shaft is driven in timed' relation to the main shaft 3 by suitable means as for example, gear trains indicated at 24;, sprocket chain connections, or other suitable means. This connecting casing 25, as indicated in Fig. 2, which permits inspection and disconnection of the parts.
When it is necessary to inspect the interiors of the cylinders of the motor, this vis readily accomplished by'simply removing the'vcylin'ders with the cam shaft and valve ating mechanism.
valve mechanism is not disturbed and the connections housed in the casing that forms a partof the cylinders, bodily from the engine base. Thus the cylinders may be cleaned or adj-usted and returned to place without any disturbance of theV valve oper- The. alinement of the y shaftin theV base, cylinders on the base,
