Be it known that I, WALTER M. a. citizen of the United States, residing in Boston, county of Suffolk, and State of Massachusetts, have invented an Improve merit in Internal-Combustion Engines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representingflike parts. v
invention relates to an internal combustion engine or motor. and is herein shown" as embodied in a'motor of the four cycle e invention has for its object to provi'd'e an internal combustion engine or motor which is of increased efficiency, economical in construction andmaintenance, easily accessible and silent in operation. To this end I employ hollow rotary inlet and exhaust valves, which are mounted to rotate in casing's integral with the cylinders of the en- V g e or motor and provided with water) 1 Jackets which form part of the water jackets of said cylinders. Provisonis made for causing the cooler water to circulatethrough the jacket of the exhaust valve before it enters thejacket of the inlet valve for a purpose as will be described. Provision is also made for obtaining an even or uniform supply of fresh gas for each cylinder and pro- VISIOD is also made for preventing leakage of the gas between the cylinders through the valvecasingsas will be described. These and otherf'eatures of this invention willbe pointed out-in the claims at the end of this specification.
Figure 1 is a plan view of a four cylinder four cycle engineembodying this. invention. Fig.2, a front elevation of the engine shown in Fig. 1. Fig. 3, anend elevation showing one method of rotating the hollow valves.

Cusron,
with the usual piston e and rod 7 by which the piston is connected with the crank shaft 9, having bearings in the crank case it. Each cylinder is provided at its upper end with ports 10, 12in its head, with which cooperate hollow. rotary inlet and exhaust valves 13, 14;, which are made in thefform of cylmders or sleeves, mounted to rotate in cylindrical valve casings 15, 16, cast integral with each pair of cylinders.
The . valve casings 15, 16 of one pair of cylinders as a, b, are arranged in line with the valve casings of the other pair of cylinders c, d, 'and are connected therewith gas tight by intermediate casings 19, 20, which are readily detachable from the valve casings attached to the pairs of cylinders for purpose of assembling and for gaining access to the valvesin case of repairs. The intermediate casings 19, 20-are of like construction and therefore only one need be described in detail.
Referring to Fig. 5, the intermediate casing 19, is shown as provided at-its ends with hubs 22, which form bearings for the rotary valve 13 and are externally'threaded to be engaged by nuts or threaded sleeves 23, provided with end dlSkS'Qlc, which are remov- ,ably secured. by screws 25 to said'nuts. The
' diate casing 19 is provided with ,an opening 32, which is preferably covered by Wire gage or other foraminous screen 33 to arrest dirt,
vetc., and if desired a like screen Zitmay be interposed between the gas inlet pipe 35 and the mouth 36 of the casing 19. The valve casings 20 for the exhaust rotary valve are connectedin a similar manner by an inter,-

vided withmeans for rendering them gas tight in their casings at a plurality of points the length of said valves, so thatgas under compression in one cylinder may not leak between the rotary valves and their casings into other cylinders or into the'exhaust, which results may be accomplished as herein shown by providing said valves with a plurality of pairs .of split packing rings 45, which are arranged so that their split ends b'reak joints as shown in Fig. 5. The rotary valves may be mounted at their ends upon ball bearings 46 in a manner well understood, and are closed at their ends and-provided at one end with stud shafts 47, 48,";wh-ich extend throu'gh removable end walls 6r caps 49 for the valve casings, and are operatively connected with the crank shaft to be driven thereby so as to make onerevolution to every two revolutionsv of the crank shaft. In the present instance, the shafts 47, 48, are provided with sprocket wheels 50, 51 which are joinedby' a link chain 52 to a sprocket wheel 53 on the crank shaft, The caps 49 may be screwed upon the valve casings as represented Fig. 6. By tachable from the valve casings, the cylinders can .be cast'in pairs and the valves quickly and easily assembled. Furthermore the valve casings of each pair ofcylinders may be provided with water jackets 55, 56, which are cast in one piece with the water jacket "57 of the cylinders, and the jackets of the valvecasings are connected togetherbetween them by a jacket 58 for the heads of the cylinders.
The water acket for the cylinders is provided with a water catedon the exhaust side of the cylinders,
creas'csthe pressure and the waterjacket for the gas inlet valve 13 is provided with a water' outlet 61, which 35 located on the opposite side of the cylin-' cool water is first admitted into the. jacket 57 of the cylinders and flows through the jacket 56 0t the'exhaust valve and greatly reduces the temperature and pressure ofj-the exhaust gases, and the water thugs-heated flows through the jacket 53 and thezja ket 5'1 of the inlet valve,' and inin pairs,
. of each pair, making the intermediate sections deinlet-60, which is loand temperature of the" explosive mixture or fresh gas. Both of these results are beneficial to the motor and greatly increase the efl iciency of the same and also serve to enable the motor" to be. run economically It will be observed thatthe gas supply pipe 35 is connected to the intermediate section 19 between the two pairs of cylinders, and as a result, the gas is supplied evenly to the cylinders of each pair. The opening in the exhaust valve may and preferably will not be provided with a screen.
