BRAKE-SHOE.

Specication of Iletters Yatent.

Patented Dec. 7, 1909.

To all whom it may concern:

resident of Suiif'erm'in the county of Rockland and State of New York, havemade and invented certainnew yand usefullmprovements in Brake-Shoes, of which the followy invention relates to'an improvementin brake shoes, and more particularly to that kind or type thereof usually known .and re v ferred to as steel back 7 shoes, that is, to a shoe wherein is employed a strengtheninV plate located at or adjacent tothe back o the cast metal body-for the purposel of hold ing to ether the fragments or sectionsof the shoe s ould the same become cracked or injured, the object .ot my invention being to provide a shoe wherein the strengthening plate may be readily and easily'` attached to the cast metal body, and. so locked thereto as to avoid any and all danger of its becoming detached therefrom.

A further object of the inventionV is tolse' vsecure the strengthening plate in position,

as will permit ot' its rea detachment from the cast metal body, after the latter hasbeen worn away in service, and thereby" permit of its further and continued use in connection with new shoes.

1V-ith these and other ends in View, the invention consistsin certain novel features of construction and combinations of parts, as will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved shoe. Fig. 2 is a view thereof in side elevation. Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is a cross sectional View taken on the line '4 4 of Fig. 1, prior to the holding pins being bent downwardly on the strengthening plate. Fig. 5 is a sectional view taken on the line 4--4 of Fig. 1, after the pins have been bent down to secure the strengthening plate in its proper position with relation to the cast metal body.

Referring to the drawings, 6 represents the castmetal body of the shoe, the upper side or surface being formed with a depression, and with the two side flanges 8, the

of the shoe, fits the strengthening plate 7, provided with the key-lug 10, and at 1ts ends with Ithe4 guide. lugs 11, this strengthening plate bein formed of sheet steel, wrought, Orother esired metal, and when' coupled with the cast metal body, lies Hush with the upper sides or surfaces of the flanges 8, as clearly illustrated in the sectional views Figs. 4; and 5 of the drawings. l

In the -body of the shoe are the pins or lugs 12, their lower ends being headed, as illustrated at 13 and anchored in the cast metal of the shoe, said ins' or lugs extending upwardly throught e flanges 8. After the strengthening vplate 7 has been placed in V'position within,the recess or depression in the backfof the shoe, these pins or lugs A12 arethen bent over onto the upper side'or surface of the plate, as illustrated in Figs. 1 and 5, thereby securely holding or lookin said plate in osition and forming an e icient connection between the two parts of the completeshoe. After the body 6 of theshoe has been worn away in service, these pins or lugs 12 may be bent'atpwrdly, as illustrated in Fig. 4, permitting the back to be removed or detached from the Worn shoe and again employed in connection with eov a new shoe, thereby effecting a great saving over the old or common types of shoes wherein the strengthening plate is scrapped with the worn body.

The-invention is exceedingly simple .in construction and cheap to manufacture, the

lugs or pins `l2 being properlyv laced in the moldprior to the pouring of t e cast metal -v therein, the heads 13 of the pins securely anchoring them in place in the bodyy of the shoe.` Furthermore, it will be understood that the back is easily andv readily attached to and detached from the body of the shoe,

thereby effecting a material saving in time and labor over those types ot; shoeswherein it is necessary to cut orotherwise remove the heads from bolts or rivets employed for the purpose of holding the plate in its proper position on the shoe.

Having fully described my invention,

what I claim as new and desire to secure.

by ILetters Patent, is

1. A brake shoe consisting of a cast metal body and a "strengthening plate located at or end Vof each of which is anchored in said body and the opposite end bent. over and upon saidplate, substantially as described.

2. A brake shoe comprising a cast metal body and a strengthening plate, and pins, one end of each of which is .headed and anchored in said body, and theoppositeend bent over and upon said plate,`substantially as' described.

3. A'brake shoe comprising a cast metal A' body provided at its back with a recess, a

strengthening plate located `within said recess, and pins, one end of each of which is anchored 1n they cast metal body,

and the opposite end' bent over and upon said plate,

whereby to removably lock the .latter to said body, substantially as described.

4. A brake shoe comprising' a cast metal body provided at its back With a recess, a plate formed with key and guide lugs and ocated in said recess, pins, one end of each of which is headed and anchored .in said body, the opposite end being bent over and Ianchored in said body,

upon said plate, whereby to removably hold the latter in position on said body, substan tially vas described. I l

'5. A brake shoe coinprisin a body provided With side flanges on its guck, and with end stops, a strengthening plate located on the back of vsaid body and bet-Ween said flanges, and lugs, pins, one end of each of which is jecting up through said anges, and bent over and upon said plate, wherebyfto. removably lock the latter in body, substantially as descri ed. Signed at New York, borough of Manhattan, in the county of New York, and State of New York, this 16th day of August, A. D. 1909.
