' To all whom it may concern:
Be it known that I, Vmron Ransom, a citizen-of the, German Empire, residing at Kiel, Germany, have invented certain new and useful Improvements in Piston-Cooling Devices for Internal-Combustion Engines,
of which the following is a specification.
The water supply to the pistons in internalcombustion engines is generally transmitted by theassistance of the cross head; and the water transmission has heretofore been carried out in this manner, that the cooling water'has been let into the piston through one of the two crosshead trunnions and a channel in the piston rod and then transmitted into the second cross head trunnion through a second channel mostly concentric with the first channel in the piston rod, and frdm there into the outlet pipe.
This kind of piston cooling device possesses "the disadvantage that the two trunnions on the cross head inclosed by the bearings of the connecting rod will have quite a diifer- The object of the present invention is now to remove this disadvantage and to enable a good cooling of the piston as well as of the two trunnions of the cross head. One embodiment of the invention is illustrated in the accompanying drawing showin the piston cooling device in cross section. he'cross head A 1s secured to the hollow piston rod B by means of a shoulder b and a nut C. The trunnions a} a of the cross head are hollow and carry studs E and F for the admittance and dischar e of the cooling water. A pipe D of smaller diameter is incloucd in the borin of the piston rod B, and by means of a sho der (1 fits tightly therein. This pipe effects in the usual manner the admittance of water to the piston, while the annular chamber formed between the pipe and the inner walls of the piston rod serves as return duct for the cooling water. In the boring of the cross head which receives the piston rod are provided Specification of Letters Iatent.

three grooves which-form annular channels Gr, H and J in conjunction with-the piston rod. Of these channels the roneG'is'jcom nected-with the hollow chambers oithe wo trunnions a and a on thecross h'ea by means of the borings K and L; the annularchannel'H on the other hand is connected with a discharge passage'in'thestudT bymeans of the boring -M, and by means of borings dit is connected with the hollow 6 chamber of the piston rod. Lastly the annular channel J is brought into connection with thejright hand trunnion aonth'e cross head by means of the boring N and by means of the borings'el with'theinside of the, pipe D. Flexible pipes, not shown on drawing, are attached to the-studs E and F, which pipes'provide the'admittance and dis-' charge of the coolin .water.
. The direction of t e coolin wa'terinpass-- mg through the cross head ls indicated by arrows lnthe drawing and will beeaisily unders'tood. The water entering throu h the stud E into the hollow chamber of e left hand trunnion a of.the cross hea' flows through the boring K, the "annular e and G and the boring into the hollow chamber of the right hand trunnion a"a;nd.from there throu h the boring N, the annular channel J, t e borings d and the pi e D to the piston (not represented in the diawmg). The heated cooling water flows back from the piston through 'the annular passage formed between the i e D and the inner wall ofthe piston the borings d, the annular channel Hh-the boring M and the outlet stud F. As t e cooling waterbofore its entering the piston, travels, instill cold condition, first through the hollow 9 head, the use .of the described cooling device forthe piston will effect in a very simple manner a good cooling of the two trunnions of the cross head. a
