FASTENING WATER-COOLED VALVE-BOXES TO THE CYLINDERS F COMBUSTION-ENGlNES.
Specification of Letters Patent.
Patented July 2, 1907.
\ Application filed uary 1,1907- Nov 355,340.
- 1 0 ing water-cooled valve-boxes to the water-cooled cylinders of combustion engines.
It is iound that with water-cooled valve-boxes which are screwed to the working cylinder oi a combustion engine difiiculties often arise in' arranging a suificient number of bolts or screws for fastening the same. The
screws necessitate-the water-jacket being cut away too much, or a very large flange must be arranged outside,
for which there is no room in most cases.
In accordance with the present invention these difii- 2 0 culties are avoided by the valve-box being secured to the cylinder with the aid of hollow screws, screw-bolts, or
the like, which extend at both sides to the water-jacket and permit the cold water to flow through their borings from the one to the other jacket.
In order that the invention may be more clearly understood, reference is made to the accompanying drawing in which one embodiment is shown by way of example, and in which:
Figure l is a vertical section through a valv box and part of a cylinder, and Fig. 2 is a vertical end elevation of part of the same.
Similar letters of reference refer to similar parts in both views.
The drawing represents a valve-box which is fastened laterally to the cylinder of an engine and 0 denotes the cylinder, 1) its water-jacket, c the passage from the cylinder to the valve-box d, e the water-jacket of the valvebox. The valve-box is connected with the cylinder by means of the hollow screw-bolts f, the nutsg of which are situated in the water-jacket of the valve-box and can be screwed upfrom without through lateral holes in the wateracket which can be closed. The cold water is introduced into the water-jacket of the valve-box and overflows through the borings of the.
screws f or the like into the water-jacket oi the cylinder (1. In this manner the water is well distributed, and
the passage 0, the sides of which are contacted most by the hot gases, is thoroughly and uniformly cooled. Further, this construction has the advantage over that in which solid screws are inserted into the water-jacket, that a considerable weakening of the sides of the waterjacket by special openings for the passage of the cold water, which are arranged besides the holes for the screws, is avoided.
While the construction of parts preferred has been described in the foregoing specification, it is to be understood that numerous changes of construction maybe made without departing from the spirit and scope of the invention, and it is therefore not to be understood as limited by the positive terms employed in connection with the description, excepting such as the state of the art may require.
What I claim, and desire to secure by Letters Patent of the United States, is:-'
1. In a combustion engine, the-combination with 3. cylinder provided with a water-cooled jacket, of a valve-box provided with a water-cooled jacket, and hollow means fastening said valve-box to said cylinder and forming a passage from the one jacket to the other, essentially as described.
2. In a combustion engine, the combination with a cylinder provided with a water-cooled jacket, of a valvebox provided with a watcr-cooled jacket, and screws or screw bolts having holes boredlongitudinally through the same fastening said valve-box to said cylinder and forming a passage from the one jacket to the other, essentially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
