ANVIL FORRIVETING GUARD LEDGER PLATES Filed June 4, 1941 2 Sheets-Sheet 2 Inventor A ttomc y Patented June 29, 1943 UNITED STATES PATENT OFFICE ANVIL FOR RIVETING GUARD LEDGER PLATES 2 Claims.

My invention relates to improvements in hand anvils especially adapted for removing and replacing ledger plates of guard fingers of the cut ting apparatus of harvesters and the like, and wherein the replacing is characterized by several riveting operations, and the primary object of my invention is to provide a superior anvil of this character which facilitates the work mentioned and provides additional facilities for the conduct of the operations involved.

Other important objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the appended drawings, wherein for purposes of illustrating I have shown a preferred embodiment of my invention.

In the drawings Figure l is a general side elevational view of the anvil showing the anvil with its flat tapered terminal applied between the ledger plate and the lip of a guard finger so as to back up a rivet used in fastening the ledger plates in place.

Figure 2 is a side elevational view of the anvil showing the lateral boss applied to the ledger plate to back up a rivet, with the said boss reaching under the lip of the guard and with the holding ring of the anvil circumposed on the guard to hold the same in position during the riveting operation.

Figure 3 is a reverse side elevational view of the anvil applied laterally to the guard.

Figure 4 is a bottom plan view of the anvil.

Figure 5 is an enlarged right hand end elevational view of the anvil.

Figure 6 is a top plan view of the anvil.

Referring in detail to the drawings, the numeral 5 generally designates the anvil in accordance with the present invention, the same comprising an elongated tapering body 6 which is substantially although not necessarily round in cross section but provided with rounded sides to facili- .tate gripping and operation of the anvil by one hand. The right hand end of the anvil is larger in cross section due to the tapering mentioned and. is further enlarged on its upper side by the beveled portion 1 by reason of which the right hand end of the anvil has the largest cross section of any part of the device and is squared and flat as indicated by the numeral 8. The bevel 1 extends laterally from the axis of the handle 6 to a sufficient distance to be useful to project as indicated in Figure 3 of the drawings.

The opposite end of the handle 6 is gently curved downwardly at 9 and slightly flattened in cross section below the bend where its sides are squared as indicated by the numeral Ill and its top flattened and downwardly deflected as indicated by the numeral I l and its bottom flattened as indicated by the numeral I2, with the axially outward terminal l3 squared in the manner of a screw-driver point. The plain flat surface. [2

is substantially parallel with the axis of the handle 6.

Projecting from the bottom of the handle 6 is the boss 14 which is round in cross section and upwardly tapered so that the lower fiat circular end l5 thereof comprises the largest cross section of the boss. The boss is tapered on a bias so as to project toward the large end of the handle 6 as indicated in Figure 1 and provides a curved reaching surface l6 which can reach under overhanging portions such as the lip H on the guard I8 so as toapply the surface 15 to the ledger plate I9 to back up the rivet 20.

Swingable on a transverse axis is the ring 2! which comprises axially aligned arms 22 and 23, shown in Figure 5 of the drawings, turning in the bore formed in the handle 6 adjacent the wide end 8 thereof, the portions 22 and 23 being connected to the terminals of a U-shape 24 which normally swingably depends in the position shown in the drawings to engage around the edge of the guard l8 as indicated in Figure 2 whereby to hold the guard l8 during the riveting operation, one hand of the operator being applied to the handle 6 and the other to a suitable hammer to strike the exposed end of the rivet 29.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of my invention thereto except as required by the scope of the subjoined claims.

Having described the invention, what is claimed as new is:

1. An anvil of the character described, said anvil comprising an elongated handle body formed at one end with a heel, a flattened laterally offset toe on the opposite end of said handle body, a laterally projecting boss on one side of said handle body, said boss having a reaching portion projecting toward said heel, and a holding ring swingably mounted on said handle body between said boss and said heel for holding a portion of an element extending along said handle body to which said boss is applied.

2. An anvil of the character described comprising an elongated handle consisting of a rounded bar tapering from one end toward the opposite end, a boss projecting from the side of said bar adjacent the larger end of said bar, said larger end constituting a heel, said boss being substantially frustro-conical in form with its larger end remote from the side of the bar, said boss being angulated toward said heel to define a reaching portion on said boss between the boss and the heel, and an article retaining ring pivoted on said bar between said boss and said heel and through which an article is to be inserted so as to be held against said boss.
