Filed July 31. 1951 INVENTOR ATTORNEY Patented Oct. 11, 1932 STANLEY WEBER, F LONG ISLAND CITY, NEW YOIB:

SZPANNER wnnnon Application filed July 31,

This invention relates to wrenches and particularly to spanner wrenches by means of which various kinds of nut devices and other equipment of a similar character used on or 6 in connection with machinery are tightened and loosened.

In view of the high speed which [modern machinery attains, manufacturers are turning more and more to the use of round nuts for purposes of safety and balance. The tool of the present invention has been devised especially for use in connection with this'class of nut devices, although it will be recognized that its use is not limited or confined thereto.

As is well understood, nut devices carried by machinery operating at high speed tend to tighten themselves, rendering removal difficult; and it is a common practice in endeavoringtoloosen or remove nuts which have been excessively tightened, to strike the free end of the wrench with light yet relatively sharp blows. The wrenches at present in use for such purpose, being composed of either pivoted or hinge connected parts, yield with a spring-like effect under the impact of the blow so that much of the force of the blow is lost. In taking many mechanical structures apart, say for example, ball bearing motors which are to be taken apart for purposes of cleaning, rewinding or replacement of the ball bearings, an object to be attained is to remove the nuts without injury thereto and without damaging the threads or other parts. In order to remove the nut devices from such special machinery, it 'is often necessary to make use of a punch or the like and in so doing to bringabout damage beyond repair.

The object and purpose of the present invention are to provide a simple and practical tool by means of which successfully to cope with the difficulties referred to and others; to avoid damage and delay, and often the cost incident to a shut-down of an important piece of machinery.

One of the objects of the invention is to provide a wrench the lever handle and spanning arms of which are without pivot or hinge connections so that the fullforce of a sharp blow, which is delivered at the free end of the 1931. Serial No. 554,249.

lever handle, will be transmitted to the nut device.

A further object is the provision of jaw or bar parts which are firmly seated and held in the arms a ainst yieldin under turning.

impulse, but w ich are capab e of ad'ustment radially with respect to the axis 0 the nut to be operated upon.

A still'further object is the provision of a tool of the character described which is furnished with instrumentalities for en aging tool-receiving openings of various kin s.

With the foregoing objects in view and others not specifically enumerated above but which will appear to one skilled in the art, Y

the invention consists of the novel construc tion, combination and arrangement of parts hereinafter more specifically described, and illustrated in the accompanying drawing, wherein is shown a single example of the invention as reduced to practice.

In the drawing, wherein like reference characters denote corresponding parts throughout the several views Figure 1 represents a top plan view of a spanner wrench made in accordance with the present invention, this view also showing in dash-dot lines the outline of a nut with which the wrench is in engagement;

Fig. 2 is an edge view and Figs. 3 to 8 are details of various types of nuts with which the wrench may be employed Figs. 3 and 4 being, respectively, plan and sectional views of one type of nut, with the sectional yiew of Fig. f taken on the line H of Fig. 3; Figs 5 and 6 being plan and edge views, respectively, of another type of nut; and Figs. 7 and 8 being plan and edge vietyvs, respectively, of still another type of nu The preferred form of construction, as illustrated in the accompanying drawing, comprises a solid elongated bar-like turning lever 10 which is shaped to be grasped by the hand and to serve as a handle. The end portion 11 of the lever is free and unobstructed. At

its opposite end the lever is formed with a pair of integral spanner arms 12 which extend n opposite directlons, spanning an intervening receiving space 13. These two inpartial section;

. tegralspanner arms may be given any shape or form desired or necessary for carrying out the invention, but by preference they curve on a semi-circle as shown in order best to accommodate the wrench tool for use in connection with round nut devices.

Each of the spanner arms 12 terminates in a head 14 which may be widened in an outward direction, that is to say, in a direction opposite to the intervening receiving space 13. Cut, formed, or otherwise produced transversely in each of the heads 14 at one side thereof is a channel or recess 15, the side walls of which constitute shoulder abutments 16 in spaced opposition. A jaw or cross bar 17 is dis osed in each of the channels 15, its fit therein eing snug so that the shoulder abutments 16. during turning movement of the lever about an axis, will prevent any shifting or yielding movement of the jaws relatively to the arms.

The transverse channels 15 may be provided, and preferablyare provided, in alignment, so that the jaws or cross bars 17 disposed therein will be in lengthwise alignment. The jaws 17 are of a length to extend well beyond the opposite edges of the head portions, and each jaw is provided at each projecting end thereof with a projection or pin suitable for entering a tool receiving aperture of a nut device. In the present instance, the projecting means carried for such purpose at the opposlte ends of each of the jaws consists of pins 18 and 19; it being noted that the pins 18 project laterally from the jaws in angular relation to the long axis thereof, while the pins 19 have projection in alignment with the long axis of the jaws.

Means are provided for adjustably securing the jaws or cross bars 17 in their channels. To this end, in the present embodiment, each of the jaws 17 is provided with a lengthwise extendin slot 20. Transversely through each of t ese slots is passed a screw element 21 which is screw-threaded into the head 15. The face of each of the jaws 17 is preferably beveled as at 22 around the slot 20 in order to provide a suitable countersink for the head of the screw. With the described arrangement, the jaws or cross bars can be readily reversed end for end in order that either the pins 18 or the pins 19 may be located within the receiving space 13 for engagement with the nut device 'to be turned. In addition to this, the jaws may be fixed in their channels in that precise position necessary for engag ing the pins with tool receiving openings as 23 of a round nut device 24. Furthermore, by this arrangement, irrespective of the preelse position in which it is necessary to fix them in their channels, the jaws are firmly held against sidewise shifting or yielding movements during the turning of the wrench about the axis of the nut with which the pins are interengaged.

In Fig. 1, the nut 24 which is illustrated in detail in Figs. 3 and 4, is shown in dashdot outline in connection with the wrench tool, and with the jaws fitted and adjusted so that the pins 18 will enter the tool-receiving apertures 23 of the nut device. In Figs. 5 and 6, I illustrate another type of nut device 25 in which the tool-receiving apertures 26 are of the open and angular t pe, the same being provided in the circum erence of the nut device. The pins 18 are adapted to be inserted in the open apertures 26 for manipulating this type of nut. In Figs. 7 and 8, I illustrate still another type of nut 27 in which circular apertures 28 extend into the body of the nut from the circumference thereof. In order to be applied to a nut device as 27 the jaws 17 are reversed end for end so that the pins 19 will occupy a position in the space 13 for engagement with the apertures 28.

When the wrench of my invention has been applied to the nut to be turned, by inserting appropriate pins in the, tool-receiving openings of the nut, a blow or blows, if it be necessary to tighten a loose nut or to loosen a tight nut, may be struck by a hammer or other instrumentality against the longitudinal edge of the lever 10 at or near its free end portion 11, the blows being, of course, delivered in the direction in which it is desired to turn the nut upon its axis. Owing to the manner in which the jaws or cross bars are seated in the rigid arms and held against sidewise movement by the shoulder abutments, a wrench is provided which, for turning purposes, is rigid from the free end of the lever or handle to the aperture engaging pins. By sharply rapping or striking on the lever adjacent its free end, the nut device engaged at two opposite points by the pins, is readily turned on its axis and hence tightened or loosened as the case may be. Since the jaws are reversible and can be adjusted lengthwise with respect to the axial center line of the nut, the wrench can be used for loosening or tightening diflerent kinds of nuts which now require individual spanner wrenches of the proper size to fit the particular unit. The spanner wrench of my invention is exceedingly simple in construction and economical in manufacture, while possessing the advantage of being sturdy and providing for the loosening and tightening of different types of nuts without injuring the nuts or the parts upon which the nuts are threaded.

Although in the present disclosure, in order to illustrate in a general waythe range of practicability of my inventlon, I have shown and enumerated three different spec1fic types of nut devices, it will be recognized that in practice my improved spanner wrench has a much wider range of utility and that 1t may be used in connection with various additional types of nut devices and instrumentalities not specifically illustrated or enumerated herein.

It is to be understood that in the further development of my invention, I reserve the right and privilege of resorting to all such legitimate changes and modifications in the form, construction and relative arrangement of the various parts as may be fairly incorporated in the spirit and scope of the inven- 1 tion as claimed.
