GEORGE E. BAILIE, 01? DENVER, COLORADO.
SAFETY-POCKET CYLINDER-HEAD.
Specification of Letters Patent.
Patented May 9, 1916.
Application filed April 12, 1915. Serial No. 20,783.
To all whomc't may concern Be it known that I, GEORGE E. BAILIE, a citizen of the United States, residing in the city and county of Denverand State of Colorado, have invented certain new and useful Improvements in Safety-Pocket Cylinder-Heads; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
My invention relates to cylinder heads for engines, being more especially adapted for use in connection with the cylinder heads of locomotives in which the cylinders occupy a horizontal or inclined position;
The object of the invention is to avoid injury to the cylinders or pistons, or both, by reason of some hard object as a nut or bolt head getting in between the piston and the cylinder head, whereby in the efli'ort to complete the pistons stroke, injury is done either to the cylinder or piston. This difficulty may result in breaking the cylinder head or in bending the piston stem.
It very frequently happens that one of the nuts employed in securing the members of the piston together, gets loose and drops down between the forward extremity of the piston and the head of the cylinder. As these pistons approach very closely to the head, normally there is not space or clearance enough to make room for an object of this size, consequently, some part of the construction must be injured. Hence, the object of my improvement is to overcome this difliculty and to this end, I form a pocket in the cylinder head of such size as to make room for a nut or other object, in case the same should drop down between the forward extremity of the piston and the head, as heretofore explained. This pocket is formed in the lowermost part of the cylinder head, the latter being reinforced sufficiently to make room for a pocket of the necessary size. By virtue of this construction and arrangement, if a nut or other ob .ject becomes loose and drops between the piston and the cylinder head, it will be shoved into the said pocket and no injury will result to any part of the construction.
Having briefly outlined my improveber.
ment, I will proceed to describe thesaine in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.
In this drawing,-Figure 1 is a fragmentary sectional view of a cylinder equipped with my improvement, the piston being shown in elevation. tion taken on the line 2-2, Fig. 1, looking toward the right.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate the cylinder considered in its entirety; 6 the piston head, and 7 the stem of the piston. The head 8 of the cylinder is provided with a pocket 9 formed in the lowest portion of the head and communicating with the piston cham- The rear extremity'of this pocket is preferably larger than its forward extremity, whereby the upper wall 10 of thepocket is downwardly inclined from its inner extremity, the wall on opposite sides being correspondingly inclined. This special construction facilitates the entrance of the object, as a nut 12, into the pocket as the piston moves forwardly toward the head. This pocket 9 necessitates the reinforcing of the cylinder head as shown at 13, in order to make it practicable to form a pocket of the necessary size for the purpose. Again, in order that the strength of the cylinder head may not be diminished by the forma tion of the relatively large cavity or pocket 9 therein, the portion 1 1 of the cylinder head below the pocket is of the same length as the longitudinal depth of the pocket, plus the thickness of its forward wall. Hence, the bolts 14 which are employed to secure the cylinder head in place, must be long enough to pass through the greater thick ness of the head where the pocket is located. In all other respects, the cylinder remains. unchanged. It will therefore be noted that my improvement is exceedingly simple and will involve practically no extra expense in the construction of cylinder Fig. 2 is a cross secheads after the proper pattern has been in alinement with the pocket and will naturally travel thereinto, under the influence of the movement of the piston head, in the regular performance of the latters funclVhile only one head of the cylinder, namely, the forward head, has been illustrated in the drawing, it must be understood that the rear head should also be equipped with a pocket 9, since it may be necessary to utilize such a pocket in the event that an article, as a nut or bolt, may be accidently left in the cylinder at the time the latter is constructed. In this event, a similar pocket in the rear head would prevent accident, since the article would be moved, during the rearward stroke of the piston, into the said pocket.
Having thus described my invention, what I claim is,-

3. A cylinder, one of whose heads is pro vided with a pocket in its lowermost portion only and extending entirely beyond the body of the cylinder and communicating with the chamber of the latter, the said pocket being largest at its inner extremity.
