WRENCH STRUCTURE.

Specification of Letters Patent. Patented May 24., 1910.

Application filed flctober lfi, 1909. Serial No.- 522,923.

invention being to provide a structure of this kind which will be extremely strong in construction, comparatively cheap to manufacture, and one which is designed as a labor saving device.

WVith these and other objects in view the invention consists in certain novel features of construction and combinations and arrangement-s of parts as will be more fully hereinafter described. and pointed out in the claim.

In the accompanying drawings, Figure l,

is a perspective view illustrating my improvements. Fig.2, is a view in side elevation of the side opposite to that shown in Fig. 1.. Fig. 3, is an end view. Fig. 4, is a view in longitudinal section, through the tool and handle, and Fig. 5, is a view in cross section through the tool and handle and taken at right angles to Fig. l.

1 represents the body of the hammer, which is provided with the ordinary opening 2 to receive a handle 3, of any desired length. The body portion 1 21317 one end is connected by a restricted neck with a hammer head 5, the latter being of general-truncated conical or tapering form, with its side wall of a len th or depth, equal to the normal depth of a wheel flange, so that when placed beside the flange the latter can be measured and if not'up tofithe standard the wheel must be discarded. This head 5 is provided with a transverse notch 6 and the function of. this notched portion is to provide a hook, which when the head is insorted within a steam pipe coupling, will engage the gasket and permit the latter tobe drawn out. On the oposite end of the body portion 1, a hook 7 is provided, which latter is made with a flattened restricted end 8, adapted for a great many uses. For example, this hook end may be utilized for raising journal box lids; for removing air hole gaskets and the like; for cleaning air hole gasket posts; for opening steam hole locks; for opening cotter pins, and removing them; and for various other uses, This hooked end is of such a length that the distance between the end of the hook and the end of the head is such that the tool affords a measuring device to determine whether or not car couplings should be discarded. In oth'ergvords if the device can be inserted into a car coupler between the knuckle and the jaw, then the coupler is worn to such a degree that it must be discarded. This hook portion 7 is provided with a triangular opening 9, and is notched as shown at 10, forming shoulders 11 and this opening, notch and shoulders are designed for removing the steam hole gaskets. The end face of the body portion 1 is provided with a tapering circular enlargement 12, which is adapted to maul or mill air hole gaskets into place. I On one side of the body portion a flat we or flange 13 is provided and this flange'is of just the proper length for measuring flat spots on car wheels; In other words if a flat spot on a car wheel is of length equal to or greater than the length of the flange or web 13, the car wheel must be discarded. On the opposite side of the body portion 1, hook shaped lugs 14 are provided, which are at opposite sides of a longitudinal groove 15, and these lugs and groove constitute a clutch to engage the angle cock handle and when taken in connection with the handle 3, the tool constitutes a lever'of a length equal to the length of the'handle, so as to force the cock open or closed as the case may be, and this is a pointof great advantage, as these cocks become tight in use.

All of the measurements of the tool are made in conformity to Master Car Builders requirements, and are therefore standard. It will therefore be noted, that a car inspector, with my improved combination tool may put the car and its attachnientsgto all of the ordinary tests required, and with the use of this single tool he is enabled to dispense with a large number of tools which heretofore he should have uscd, and which in a great many instances he has neglected to use and has merely guessed or otherwise neglected his duty. \Vith this tool the inspector can quickly put the car to all of its ordinary tests and the device is therefore one of great utility and yet ofextreme simplicity. I

Various slight changes might be made in the general form and arrangement ofparts described without departing from my invention, and hence I do not restrict myself to the precise details set' forth, but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

Having'thus described my invention, what I claim as new and desire Letters Patent is:

device of the character described, consisting of a single integral casting having an openingtherein, a handle in said opening, said casting having a groove transversely of the casting at one side, and longitudinally withlthe handle, and integral inwardly curvin lugs on said casting at opposite sides 0 the groove, substantially as described] v In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
