J? MAH-hER- INTERNAL COMBUSTION ENGINE" Dec. 24, 1935.
Filed Jan 16 1933 Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE COIWIBUSTION ENGINE Johann Mahler, Augsburg, Germany, assignor to Maschinenfabrik Augsburg-Numberg A.-G.,
' Augsburg, Germany, a corporation of Germany Application January 16, 1933, Serial No. 651,881 In Germany January 26, 1932 4 Claims.
This invention relates to internal combustion engines.
One object of the invention is the provision of an engine cylinder construction-so arranged as 5 to afford quick and ready disassembly and lateral removal of an engine cylinder after disconnecting'it from the cylinder head.
Another object of the invention is the provision 01' an engine having cylinders that can be readily so that the cylinder can be readily disconnected from both the cylinder head and the engine crank case without disturbing the relative positions of the latter.
Other objects and advantages of the invention will be apparent from the following description, the appended claims and the accompany drawing, in which- Fig. 1 is a view of an engine embodying the present invention shown partly in central vertical section;
Fig. 2 is a side elevation of the engine; I
.Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.
Fig. 4 is a section on the line 4-4 of Fig. 1 with the piston and its connecting rod omitted.
Referring more particularly to the drawing by reference letters, a designates the base or crank case frame of a single acting engine, herein shown as of the multiple cylinder stationary type. Vertical columns or rods rigidly interconnect the base a with the cylinder head structure d. The various cylinder heads of the engine may either be cast all in one piece, or welded or otherwise secured rigidly together. The cylinder heads contain the various valves p. An oil pan b is detachably secured to the lower side of the base a. The various cylinders e, at their upper ends, 50 v are'individu'ally detachably secured to the lower side of the cylinder head structure d. The upper ends or the cylinders are preferably flanged outwardly, and these flanges are bolted to the cylinder head structure from below by bolts 3. The
lower endof each cylinder is held in its proper.
position with respect to the crank case by an enclosing means shown in the form of rings secured by bolts q on the upper crank case wall 11.. Each encircling ring and the cylinder are relatively movable in an axial direction, so that the -5 ring can be moved up on the cylinden'the ring being preferably sectioned or split into two parts i and f, as shown, so that these parts can be readily withdrawn'laterally. The two parts" of the ring are seated in an opening a in the crank case which is somewhat larger in size than the outside diameter of the lower cylinder end, as shown in Fig. 1. When the bolts 1 are removed, it will be apparent that the ring portions and F may be moved upwardly a sufficient distance to permit their subsequent lateral withdrawal from both the cylinder and the crank case, leaving a space between the cylinder and the crank case. After disconnecting the bolts which securethe upper cylinder flanges to the cylinder head structure d, a cylinder maybe moved down partly into the opening g in the crank case, and then tilted laterally to the position shown in the dot and dash lines in Fig. l. The cylinder may then readily be withdrawn entirely, this disassembly taking place without disturbing the normal position of the cylinder head structure d, or its normal relationship with respect to the crank case.
The upp r portion of each cylinder is.provided with a chamberi for cooling liquid, having suitable fluid connection with a cooling chamber provided in the cylinder head structure. Cooling liquid is supplied to the chamber i by means of a sectional pipe, the various T-shaped pipe sections a being connected by means of flanges kbetween 85 which are preferably packing rings of rubber or the like. The connected pipes form 'a common conduit for the supply of cooling liquid to the various chambers i, but when it is desired to remove any cylinder it will be apparent that the flanges k of the pipe. of that particular cylinder may be readily unbolted from the adjacent pipes to permit the lateral withdrawal of the cylinder.
Each part I I" of a cylinder enclosing ring is 5 provided with a section of an oil baflle plate,'the oil baflle section 11. being welded, bolted or integrally formed with the section I while the plate portion n is similarly provided on the section f An opening 0 is provided in the two baille plates 50 1t 12. through which the connecting rod m extends, the baffle plate serving to a large extent to prevent the passage of oil from the crank case up onto the cylinder walls and time into the combustion chamber. The lates n n are at course removed with 66 loosening the connection between the 2 aosaass thering sections'fl fi'duringthe disassemhlycia cylinder.
Ai'ter a cylinder .has been removed from the engine-ii desired, the piston can be disassembled from the conneotingrod, and the connecting rod itself canbe readily separated by removing the screws which-- attach the split together, the spacey provided in the crankcase being sufliciently large to permit the withdrawal of the connecting .rod through it even where the cranki'pin diameterislarge asinahighspeed engine. The parts canbe readily reassembled by carrying-out the sameoperations as i above described-but in a reverse order.
In with this invention it will-be apparent that. the 1y or any cylinder; or of any cylinder, piston and piston rod may-be accomplished very quickly without disturbing the normal relationship 01' the cylinder head with respect tothe base-orcrankcase. Buehan arrangement is particularlydesirable where there is very little space between the top of the engine and the ceiling as such limited room conditions are not objectionable wherethe cylinder is removed in a lateral direction. The cylinder arrangement,v
however,: is -applicable-t'o any condition in which the removalorlyoi'thepartsin avery short time is For example the-construction quick removal of the cylinder in a very manner to facilitate the replacementforgrindingv of the valves without head anditheengine crank case; l
While theiorm oi' apparatus herein. described constitutes a preferred embodiment of the invention, it is to be that the invention is'n'o't limited to this precise term of a'pmi'atus.-
and that changes'may-be made therein without departing from the scope of the invention which is defined in the appended claims.
