1 BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 739,605, dated September 22, 1903.

. Application filed OotoherQ, 1902. :Serial No. 12?,3 73. (No model.)

For the purpose of securing the shoe proper to the head several difierent forms of fastening devices have been adopted, that most generally used consisting of a hook or'l-ug cast integral with the shoe and at one end thereof, under which fits the corresponding end of the head, the opposite end of the head being secured to the shoe by means of a bolt or post passing through openings formed in said shoe and head, said bolt or post being enlarged at one end to prevent its passage entirely through the opening in the shoe properand its opposite end being provided with a slot or opening for the passage of a key. These fastening devices, however,'have met with several objections'namely, that the iron lug or hook is frequently broken in handling and during transportation, thus rendering the shoe absolutely worthless. Further, in order to allow the insertion ofone,

end of the head under the cast-iron hook or lug in assembling the parts the bolt or post must be removed, thereby necessitating the formation of this part as a distinct and separate piece from the shoe andhead. To partially overcome these objections, it has been attempted to form the hook or lug of a separate piece, usually of steel or other comparatively hard and tough metahand anchor or secure the same in the metal of the shoe during the casting operation. Such construction, however, has been found impractical, owing to the fact that the metal around the base of the hook or lug becomes too rapidly chilled or cooled, and as there is but a small quantity of metal between said base and the extreme end of the shoe the strength of the latter is thereby greatly impaired, and, further, the belt or post for securing the opposite end of the shoe must, as in the first instance, be made separate and removable from the other parts or portions of the head and shoe.

The object of my present invention is to overcome the objections raised against the above and other forms of fastenings; and it consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and specifically pointed out in the claims.

In the accompanyingdrawings, Figure 1 is a plan view of a brake-shoe constructed in ac cordance with my invention. Fig. 2 is a side view thereof with the head attached, the head being shown partly in section. Fig. 3 is a similar view showing the position of the head during the operation of assembling the two parts. Fig. 4 is a detached view in perspective of the fastening-hook.

' Referring to the drawings, 4 represents the head, and 5 the shoe, the former consisting of two side plates or flanges 6 and the base-.

plate '7. V

In one end of the shoe 5 is secured the hook 8, preferably formed from a wrought or malleable iron bar or rod and bent into the form as illustrated in Fig. l-that is, with the two horizontal arms 9 and the loop 10 forming the hook proper, the loop being inclined, as illustrated in Fig. 3, in order to allow of the insertion of one end of the plate 7 under the same, while at the same time the opposite end of the plate is raised in order to clear the top'of the bolt or post 11, hereinafter referred to, in assembling the parts. To moresecurely anchor the hook in the cast metal of which the shoe 5 is formed, the ends of the arms 9 are somewhat flattened, as shown at 12, the book being inserted in the mold duringthe operation of casting.

In the opposite end of the shoe is secured the post or bolt 11, its lower end-13 being the hook 8, being inserted in the mold during the casting operation, and thereby securely held in themetal of the cast-iron shoe.

, In assembling the parts one end of the plate 7 of the head is inserted under the inclined hook or loop 10, the opposite end of the plate 7 being raised, as illustrated in Fig. 8. The post 11 is then passed through the opening 16, formed in the plate 7, as illustrated in Fig. 2,whereupon the key 15 is passed through the opening 14 in the post 11, looking those respective ends of the head and shoe together. By a slight blow upon the hook or loop the latter is then bent downwardly until it bears upon the upper surface of the plate 7, as illustrated in Fig. 2, thus completing the locking together of the head and shoe.

In order to subsequently detach the head 4 from the shoe 5, it is simply necessary to remove the key 15 from the post 11, whereupon that end of the head may be raised until it clears the top of said .post, the tilting of the head slightly bending the hook 10 and allowing of the withdrawal of the plate 7 from engagement therewith.

From the foregoing it will be understood that the objection to the loose postis entirely overcome, and, further, that by forming the hook from a malleable or wrought iron bar or rod it will have a far less chilling effect upon the iron during the casting of the latter than when formed in the manner as first suggested, is far cheaper, and more safely and securely anchored in the shoe.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

1. A brake'shoe having, as a means for attaching to a brake-head, a malleable wire skeleton hook.

2. A brake-shoe having as 'a means for attaching to a brake-head, a malleable wire hltlqok embedded by casting in the metal of the s 00.

'wardly upon the head when the parts are assembled, and provided at its opp site end with a malleable embedded stationary post, substantially as described.

5. A brake-shoe consisting of a body portion provided at one end with a hook, said hookbeing formed from a wrought-metal bar or rod, the opposite end of the body of the shoe being provided with a post, substantially as described.

6. A brake-shoe consisting of a body portion provided at one end with a hook, said hook being formed with two horizontal arms and a loop or hook proper, and means provided at the opposite end of said body portion for seeuringit to the head, substantially as described.

7. A brake-shoe consisting of a body portion provided at one end with a hook, said book being formed from a wrought-metal bar or rod and with two flattened horizontal arms and a loop or hook proper, said horizontal arms being anchored in the metal of which the body is formed, and means located at the opposite end of the shoe for fastening the same to the head, substantially as described.
