ASSIGNOR TO THE CLEVELAND HARD- FERRULE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed December 7, 1916. Serial No. 135,549.

T 0 all whom it may concern:

Be it known that I, Masons E. KANTER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ferrules, of which the following is a full, clear, and exact description.

This invention relates to ferrules for swingletrees, neck yokes and the like. The principal object of the invention is to provide a sheet metal ferrule which will not spread when the swingletree or the like is driven into the ferrule, and which is otherwise strong and durable, and which can be pro duced at a cost not in excess of the cost of the ordinary malleable iron ferrules which have been generally used heretofore.

The invention resides particularly in the manner of forming the joint between the edges of the metal sheet from which the ferrule is made, or in the means for locking the joint or the edges of the sheet against spreading or opening. The invention resides also in the manner in which the eye is formed on the ferrule at the joints, and in its more specific aspect the invention resides in the combined joint holding and wear plate or tongue which extends across the joint through the eye, and which in one form of the invention consists of an integral tab or tongue, and in other forms consists of a separate piece with shoulders or the like for positively locking the joint against spreading.

In the accompanying sheet of drawings wherein I have shown several forms of my invention, Figure 1 is a perspective view of a single or double tree ferrule, and one way in which it may be used; Fig. 2 is a section substantially along the line 22 of Fig. 3, looking in the direction indicated by the ar rows; F 3 is a section through the ferrule substantially along the line 3--3 of Fig. 2, looking in the direction indicated by the arrows; Figs. 4, 5, 6, 7, and 8 are views similar to Fig. 2, showing different modifications or forms of the invention; and Fig. 9 is a perspective view showing the partially completed ferrule before the sleeve is closed and the joint locked, and this view showing the type of ferrule illustrated in Fig. 8.

The ferrule in all of its modified forms is formed from sheet or rolled metal and includes a tapered sleeve 10, in which is adapting. In addition,

ed to be driven the swingletree, neck yoke, or other wooden member also provided with an eye or loop 12, through which is adapted to be passed the hook, ring, clevis, or other member 13, for example, as illustrated in Fig. 1.

In all forms of the invention the edge portions of the piece, from which the sleeve 10 1s formed, are brought together and positively locked in one manner or another, and in all modifications the eye 12 is formed in two parts,.or from loops which are struck up from the edge portions of the piece.

In a device of this character it is essential that the joint where the edges of the sheet or sleeve meet, be fastened together so securely that there will be no liability of spreading under the severe stresses which are imposed on the ferrule when the wooden part 11 is driven into the same. Heretofore the ferrules have usually been formed from malleable iron, the entire ferrule being. cast in one piece, and while many attempts have i been made to produce sheet metal ferrules,

none have been produced which were entirely satisfactory, due to the difficulty of forming a proper joint which is proof against spreading, and in forming the eye. Other disadvantages of the sheet metal ferrules heretofore proposed or produced, are the difiiculty of manufacturing them, and the high cost of manufacture as compared with cast metal ferrules. The ferrules constructed in accordance with my invention overcome the disadvantages of the sheet metal ferrules heretofore used or proposed for use, and not only have proven to answer all requirements, but to have certain advantages over the cast metal ferrules, as will be explained.

In Figs. 1, 2 and 3, the joint is formed by a combined locking and wear plate 14: which extends across the joint through the eye, and is spot welded at two or more points on both sides of the joint as indicated at 14, and in addition is provided with shoulders 14* which engage on opposite sides of the eye and positively lock the joint against spreadthe two loops forming the eye 12, are spot welded together at a plurality of points as indicated at 12. In

the modification now being considered, the plate or piece 14 is substantially Z-shaped, inasmuch as it has two locking shoulders 14!, at diagonally opposite corners.

11. The ferrule is i tiallyH-shaped, this plate being provided with four shoulders or locking lugs 15, which engage the base of the eye at the four points, and so lock the parts against spreading. 7 This plate is also spot welded as indicated.-

order that 1t may be inserted'through the eye. To avoid the bending of the plate, the

latter may be formed in two' parts, .as 1nd-icated at 16 in Fig. 5. The division between the two pieces forming the plate is at the line 16, which is centrally of the eye. When the plate is spot welded to the sleeve, part of the spot welds may be made on the line 16 as well as at the other points so as to weld-the twoparts together as well as to the sleeve. I 7

In. Fig. 6 the ferrule is provided with a locking plate 17, here shown in the form illustrated'in Fig. 2, and in addition is provided at the ends of the ferrule,.j ust outside "or beyond the eye, with tabs or tongues 18 which are integral with one edge of the sheet or piece forming the sleeve, and extend across the jointand are spot welded as indicatedat 18 to the opposite edge portion of the piece or sheet.

In the construction shown in Fig. 7 the ferrule is all in one piece, the edges of the sleeve 10 being locked together by integral tabs or tongues which extend across the joint from "one edge portion of the sleeve,

and are spot welded to the opposite portion.

These tabs include a central tab 19 which extends through the eye and is struck from the loop forming one-half of the eye 12, and two tabs 20, whichyare at the ends of the sleeve, justoutside of the eye, and extend across the joint in a similar manner.

' In all the constructions so far described, the looking or fastening pieces which extend through the. eye, whether in the form of separate plates or pieces or of integral tongues or. olnt aga nst spreadlng, but as reinforcing wear plates or pieces which are engaged by I the ring or hook 13, as clearly illustrated in Fig. 1.

In-Fig. '8 the edge portions of the sleeve are positively locked together and held against spreading by a wedge-shaped tongue :21 on one edge of the piece forming the sleeve, and engaging in'a similarly shaped slotlor notch 21 in the opposite edge, the

parts being thns locked together at a centr lal o the wedge-shaped tongue 21 pulling or moving slightly out of the wedge-shaped notch the wedge shaped tongue and'the portionof the piece immediately surrounding it may be'welded together as indicated at 21".. In

tabs serve not only to hold the.

eye.

Fig. 9 is shown a perspective view. just before the ferrule is completed by bringing the parts together to form the joint and welding them together; i

It will, be understood that with all the constructions here illustrated, the two loops forming the eye will be Welded together as illustrated in Figs. 1 and 3, or otherwise if The plate 15 of Fig. 4 must be bent in I necessary. 1 7

While I have illustrated several forms of my invention, I'do not wish to be confined to any ofthein as far as my invention in its broad aspects is concerned, for other ways of constructing the ferrule-and embodymg the broadfeatures of my invention may occur to those skilled in the art.
