CUTTER PIN TOOL Filed Dec. 27. 1922 WITNESS;
ATTORNEY iii Patented Nov. 27, 1923.
JOHN A. BAY, OF NEW PHILADELPHIA, OHIO.
COTTER-PIN TOOL.
Application filed December 27, 1922. Serial No. 609,248.
7'0 aZZ whom it may concern:
Be it known that I, JOHN A. HAY, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented new and useful Improvements in Cotter-Pin Tools, ot' which the following is a specification.
This invention relates to tools and has for its object the provision of a novel tool for the purpose of spreading and properly"' bending the cotter pins for holding them in position.
An important and more specific object is the provision of a tool 0t this character which is formed in one piece and which is operated by one hand, the device including a chiseldilre wedge member initially insertable between the prongs of a cotter pin for ell'ecting spreading, and the tool further including side lugs or wings by means of which the prongs of the cotter pins may subsequently be-bent to the desired angle.
An additional object is the provision of a tool of this character which will be simple and inexpensive in manufacture, highly eihcient in use, durable in service and a general improvement in the art With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:
lligurc 1 is a tool,
Figure 2 is an elevation thereof showing the first use thereof to spread a cotter pin and Figure 3 is a similar view showing the tool used tor subsequently bending the prongs of the cotter pin.
Referring more particularly to the drawl have shown the tool as comprising an elongated shank 10 formed of suitably tempered steel. While it is not necessary have shown and prefer to provide one end of this shank with a hammer head 11 having the usual claw 12 so that the tool will be adaptable for use for more than one purpose. The other end of the shank is cut away at both sides as shown at 13 to define an elongated wedge let and formed perspective view of the power.
integrally upon one edge of the wedge shaped portion near the end thereof are laterally extending curved lugs or books 15 which are of course spaced away from the sides of the wedge shaped end.
In the use of the device, the cotter pin .A- is placed through the hole B in the piece to be secured and the operator then inserts the end of the wedge 14: between the prongs of the cotter pin and priesthe prongs apart, After this is done, the operator removes the tool from the initial position describet and then engages the wedge 14 and one lug 15 against the outside and in deot a prong respectively and pries again to bend the prong to the proper angle to insure proper holding action of the pin. Both prongs of the cotter pin are of course treated in the same manner and it will be apparent that after the bending is effected there will be no question as to the holding The hammer end of the tool is used for further bending or straightening up cotter pins to be removed and in this way it is apparent that the tool will be a great time and labor saver and consequently a boon to automobile repair men and other mechanics.
While l have shown and described the proi'i'ored embodiment of the invention it is ct course to be understood that I reserve the right to make such changes in the form, constructi and arrangement of parts will not depart from the spirit of the in rention or the scope oi the subjoined claims.
I claim:
1. A tool of the character described cont prising an elongated shank having one end tapered into a wedge shape and provided at opposite sides of the wedge with lugs overlying the and spaced therefrom- 2. A tool ot'tho cl'iaracter dc 10d comprising an elongated shank ban one end a "l I tu'ovided pposit sidesv of the wedge with lugs overlying ne same and spaced therefrom, the lugs beingformed integrally with the shank and extending substantiallyentirely across the wedge.
In testimony whereof I aflix my signature.
Jenn A. HAY.
