UNITED STATES -ATENT Yb all whom it may concern: I A

Be it known that I, WILLIAM F. FREIDAG, citizen of the United States, residing at F reeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements 1nInternal-Combustion Englnes, of which the following is her in which lie both cinnmunicates therewith by a specification, reference being had therein to the accompanying drawing.

The generalobject of this invention is to provide an improved internal combustion engine "adapted to use heavy hydrocarbon 'uel, the special devices employed preferably being such that they mayreplace anal0 gous parts o f the-ordinar engine of similar type using gasolene or the, like light hydrocarbon.

The novel features are found-in inder head and head being the cylattachments thereof, the providedwith an exhaust chama heavy oil passage and an air and f el channel leading to the interior of the cylinder. v

In the accompanying drawings, Figure 1' is a plan view of the cylinder head and certain attachments, other accessories not involved in the invention not being shbwn. Fig. 2 is a side elevation of the same devices. a certain small reservoir adjacent to the head being shown in vertical section. Fig. 3 is a section on the line 3-3, Figf2, a second small reservoir being shown in plan view. Fig. 4 is a section on the line 4-4, Fi 3.

In these views, A represents a hollow cylinder head provided with bolt holes "B, B by which i t may be securedtothe ordinary cvlinder.

D leads from the margin of the head. Without the head is a small open reservoir E into which heavy oil from any suitable source is introduced by a pipe E and from which a small channel E in the body of the head leads inward ard again outward, its end opposite the reservoir being closed by a screw 'plug E or the'like, which permits opening the passage for cleaning. This channel passes below the passage D and means of a passage F, controlled by a valve F a hand wheel F or the like. the liquid in the reservoir may be discharged uniformly into the passage D, whether or not the supply to the reservo'r is invariable,

In order that Specification of Letters Patent. Application filed Tilly s, '1910.

also provided with an exhaust valve Gwhich I admits the exhaust gases from. the cylinder into a largechamber G whence they pass out through an opening G This chamber extends around both the passage D and the so that, these receive the heat of the gases and transmit it to the material on its way to the admission valve. I also I novelty, for gasolene or light hydrocarbon liquid. This reservoir is provided on one side with a large nipple or tubular projec provide a sccond reservoir I, without tion which is screwed'into the outer open end of the passage or mixing chamber D,

which as appears from F igs. 2 and 4 is chamber G: (F 4) and still farther above that portion of the passage E which'is closed by the plug E As Indicatedin' Figs. 1, 2, 3, air enters the chamber D through the structure I and its nipple, and a valve .1 admits or cuts off gasolene so that the entering air is otherwise. Such carbureting devices being very common and well known are not here shown in detail, the only thing Here im portant being-that air enters the chamber D freely and that it may at will be supplied any ordinary device for such purpose. Owing to the fact that the liquid in the constant-level open reservoir E of the exhaust and even if the liquid should be while in the passage, since the reservoir is tank. a

It is obvious that since the exhaust gases at every impulse sweep over the conduit E and around the chamber D, and since the conduit lies between the exhaust chamber and the cylinder space from which the gases come, the chamber D and the conduit are always highly heated when the engine is running. If the engine be started as a gasolene engine the valve F being closed and the valve I being open, the oil in the conduit E is quickly heated, and if the valve I be then closed and the valve F be opened, the heavy oil is instantly substituted for the vaporized no harm could result a sort of expansion carbureted or i 'IS always a little above the outle'tbf the I passage. E that passage is normally full;

. valvei controlling the delivery head of place of the gasolene, as the motor fuel; and obviously the reverse substitution may thereafter be made at any time. I

Ordinarily the head is a single piece cored out to form the working passages and to avoidunnecessary weight, and it is a matter of. practical mo cut that it can replace the other constructions, when it is desired to change from light to without great expense. In such case it onlynecessary to bolt 1; The combination with a cylinder head. provided with an internal exhaust chamber,
