umreo srArEs WILLIAM W. WOERPEL, 0F DODGEVILLE, WISCONSIN;

WRENCH.-

Applieation filed March 3, 1921. Serial No. 449,384.

T 0 all whom it may concern Be it known that I, \VILLIAM TV. WVOERPEL, a citizen of the United States, residing at Dodgeville, in the county of Iowa and State of Visconsin, have invented certain new and useful Improvements in Wrenches, of which the following is a specification. a

This invention relates to new and useful improvements in wrenches and more particularly to what is known as a spark plug wrench.

The primary object of the invention is to provide a wrench of this character which may be permanently carried on a cylinder head under the hood of an automobile and ready for use at all times.

A further object of the invention resides in providing a wrench struck from a single sheet of metal and adapted to be carried on a cylinder head so that it may be removed for use or retained, and a spark plug applied thereto after the separation of the parts, as may be desired.

A. still further object resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

With these and other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim.

In the accompanying drawing forming a part of this application,-

Figure 1 is a front view, wrench applied to a motor, and

Fig. 2 is a perspective view of the wrench.

In describing the invention I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views, and in which 1 designates the cylinder head of an automobile motor having thebolts 2 therein. My invention contemplates the provision of a wrench which is adapted to be carried on the cylinder head at all times so that it may be ready for use either by removing the same from this cylinder head or by apply ing the spark plugs thereto after the separation of the parts thereof, and which will in no way interfere with other parts of the motor. a

My wrench consists of an elongated sheet showing the ofmetal 3 stamped from a blank and preferably tapering smaller toward its one end, the latter end being bent angularly as shown at 4 to form a lateral or angular lug or the like. This angularly bent portion 42 is provided with anopening 5 through which one of thecylinder head bolts 2 may be disposed, so that the body proper 0f the wrench will be positioned vertically with respect to said cylinder head. I have shown my wrench in connection with the cylinder head bolt, but it will be understood that the same may be secured to any other bolt in connection with the cylinder, if desired.

The body of the wrench is provided with a g"hexagonal opening 6 and a one inch hexagonal opening The advantages of such a wrench as I have herein described and shown in the drawing are many and may be greatly appreciated by automobile mechanics and others who have had occasion in the use of automobiles to remove spark plugs while on the road. Usually mechanics and drivers utilize a pair of pliers, which are close at hand, when it is desired to remove a spark plug. When it becomes necessary to disassemble the plug in order to clean the parts thereof, it then becomes necessary to have a wrench in addition to the pliers, and two such tools are not always handy. With the use of such a wrench as I have provided, it will be seen that it is only necessary to remove the plug from the cylinder and in' sert the body of the plug in the one inch hexagonal opening while the pack nut is loosened with the pliers or wrench which is at hand. If the plugv is removed with a wrench that fits the body of the plug, then it is only necessary to place the pack nut into the hexagonal opening of my improved wrench and loosen the parts. Thus, it will be seen that the one inch opening fits the body of the standard sized spark plugs and the opening fits the pack nut of standard sized spark plugs.

Of course, it is to be understood that this wrench may be removed from its permanent fastening in the cylinder head and applied to use, but it is particularly desirable for use when positioned on the cylinder head, as I have shown the same in the drawing. I preferably provide openings of it" and 1" respectively, and where spark plugs are at a variance with the standard sizeit will be found that one of the two openings in my improved Wrench Will be applicable regardless.

In making my improved Wrench I prefer that the same be stamped from gauge steel and in View of its simple construction the same may be stamped With a single operation, and the angular portion bent with a second operation. The construction of the Wrench being so simple enables the same to be manufactured at an extremely low cost and sold at a minimum cost, so that the same may be applied to use on all cars noW in use.

From the foregoing it Will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention, and While I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to Without departing from the spirit of sacrificing any of the principles of the invention.

l/Vhat I claim is As an article of manufacture, a spark plug Wrench stamped from a single blank of flat metal tapering narrower in Width toward one end thereof, the last mentioned end being bent at right angles to form a base support therefor and provided with an opening, whereby the same may be secured to an engine casing, the remaining body portion of said blank being extended therefrom and having varied sized vertically aligned openings therein designed to specifically fit predetermined portions of a spark plug and form a Wrench therefor, in close proximity to the spark plug openings of the engine cylinder.

In testimony whereof I affix my signature.

WILLIAM W. "WOERPEIJ.
