Application led November 22, 1926. Serial No. 150,095.'

VThis invention relates to tools and has special reference to a' tool for driving out hub bushings and bearing cups. l

lThe principal object of the inventionis to provide, as a new article of manufacture, a novel toolfor driving out the bushings used in automobile wheel hubs, the tool being constructed of a single length of rod metal, preferably steel, and round in cross-V `,section as well as being resilient in character; the length of rod being bent and forged to produce the particular tool.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and: l Y

In the formation of this tool a suitable length of round steel rod is taken and bent centrally of its length` as at 10 so that there is provided a pair of handle portions 11 which are circular in cross-section and which contact throughout their length. At the bend these handle portions are forged as by hammering, pressing or other suitable shaping operation of like character, so that the combined cross-sections of the two por#v tions appear substantially rectangular. `At

the same time the end at the bent portion is attened as at 12 to form a .striking surface for a hammer or other percussive implement. From the lhandle portions 11 thev rod is continued forwardly and divergingly, the diverging 'portion adjacent the handle being forged to form a pair of flat spring portions 13 whichareflatly rectangularin cross section with their widerl surfacesopposed so that they can readily spring towardand from each other. Forward of the spring portions 13 the rod is continued'in its.

regular circular cross section and is then terminated at each end in anjoutwardly inclined terminal portion 111.The end faces of these terminal portions are beveled at an angle to the axes of the portions, the bevcling being such that the end faces lie inthe same plane. Furthermore, the outer sides of these terminal portions lare flattened so that when-the handle' 11 is inserted through a hub and its bushing these flattened vportions contact with the outer endof the bushing andy formcam surfaces yforcing the terminal portions 14 togethen These flat outer faces are indicated at 15 and the fiat beveled forward facesl at 16. .'It vwill thus be seen that. the tool thus constructed is an article of manufacture formed from a single llength of rod forged and shapedy Jtoprovide a highly efficient bushingremoving tool.` i

so; 'Y

In the form shown in Figs. 7 and 8 the tool is made by bending and forming a rod as inthe form previously described but one of the springY portions 13 Vis formed, 'either by splitting or by welding a piece of the rod thereon, to' provide a ,thirdv spring portion 19 terminating in a portion 2O of the normal rodY cross section and having an-angularly disposed end 21. (bviously', the Athree "'H spring portions and their ends will be evenly spaced to lie 120 degrees apart as shown in Fig. 8. f o

In'the form shown in Figs. 9 and 10 the tool is made in two parts, one part being termed the inner part and being identical in form' and construction with the type shown .I

in the first siX figures ofthe drawing. The other or outer part is likewise formed from la single length of rod preferably of the same cross section as 4that from which the inner Vpart is formedl This second length of rod l is bent and forgedto provide an limpact receiving head portion 22 and a pair of handle portions 23 which lie in the grooves between the portions 11. Opposite the spring portions l13) the second rod is Hatten-ed to provi'de spring portions-24 which terminate forwardly in'portions 25 of the normal rod cross section andhaving angled ends 26 like the ends 15. In this case the outer'portion has its legs disposed in a plane ,at` right angles to the legs of the inner portion.

In Aeach ease it will be seen that Athelbasic construction is that shown in the first form.

In operation, as indicated above, the tool is passed through the hub handle. end first until the surfaces 15 engage the outer end of the bushing. Then the handle is grasped and the tool pulled further through the hub. The usual notches inthe collars 16 of the hub 17 assist in guiding the tool and when the terminalportions 14 have pass-ed ,inwardly behind the bushing 18 which it is desired to reinove, they will spring out and the bevel faces 16 williengage the inner face of this annular bushing. vr1`hen by striking on the ,face-12 of the tool end vith a hammer or the lilfre the bushing 18 is quickly driven ont.

Vtially rectangular in cross-section, the rod being provided with portions. 4extending n diveigingly from the handle forming'portions and flattened to produce spring sections i -irlatly rectangular in cross-section with their wide sides opposed, the rod being continued beyond the spring sections in short lengths of the original cross-section, the rod further havingloutwardly bent extremities having end surfaces normally in the same plane and angularly disposed with reference to the respective axes of said terminal portions. V- 2. A. bushing driving tool consisting of a single length of resilient rod metal bent cen trally of its length in an abrupt bend to form a. handle portion consisting of two parts of the rod arranged in contact throughout their length, the parts adjacent the bend` being formed intoan end for receiving blows from al percu'ssive implement and being substantilflly rectangular in cross-section, the rod bei-,ng provided with portions extending dvergngly from the handle .forming p0rtions and flattenedto produce springV sections yflatly rectangular in cross-section with their wide sides opposed, the rod being continued beyond the spring sectionsin short lengths of the original cross-section, the rod further having outwardly bent extremities having eiid surfaces normally in the same plane and uangularly disposedwith reference to Uthe respective axes of said terminal portions, the cuter faces of the terminal portions .being formed to provide flat surfaces acting as cams upon the insertion of the tool through a'hub. y
